- Abstract
This study aims to reduce the skills redundancy in ecology graduates by developing an employer-tailored work-"simulated" learning curriculum. Furthermore, we evaluate the overall potential of work-simulated learning (WSL) as a key pedagogic component of a work-"integrated" learning (WIL) framework. We employed the DACUM (Developing a Curriculum) approach that encompassed i) surveying ecology-facing employers and job descriptions, ii) creating a programme of WSL, iii) a comprehensive review (student questionnaire and Industrial Steering Group workshop). A two-tiered curriculum was created; 15-credit FHEQ-5 residential field course and a 20-credit work-simulated learning FHEQ-6 module. Simulations included Phase I Habitat mapping, protected species surveys, and Preliminary Ecological Appraisals. Students developed greater knowledge of employment opportunities, enhanced technical skills, and improved their CV and employability. The steering group substantiated and validated the WSL strategy, supporting the high relevance for enhancing graduate employability, while identifying curriculum gaps and areas for refinement. These outcomes highlight the wide-reaching benefits of practice-driven WSL opportunities as a key component of a wider WIL framework. HIE-employer interactions are also critical in ensuring content relevance; however, we recommend the faculty exercise pragmatism by employing suitable pedagogic strategies to ensure they conform to the constraints of HEI while satisfying employer needs.

St. Clair-Thompson, Helen and Devine, Lucy
- Abstract
Previous research has found that mental toughness is a predictor of attainment in higher education, but there is little empirical research investigating the underpinnings of this. Two studies were therefore conducted to explore why mental toughness may be important. In Study 1, 123 undergraduates completed measures of mental toughness, flow, engagement with feedback, and reported their academic attainment. Components of mental toughness, particularly commitment, were related to flow, engagement with feedback, and academic performance. Flow and engagement with feedback were found to be significant mediators of the relationship between the commitment component of mental toughness and academic performance. In Study 2, 79 participants completed a measure of mental toughness and were assigned to high or low mental toughness groups. They then completed two mathematics tasks, and received either positive, negative, or no feedback between the tasks. Those with lower mental toughness were found to perform less well following negative feedback than those with higher mental toughness. The results are discussed in terms of implications for educators who provide feedback and seek to encourage students to engage with that feedback.

- Abstract
Social workers are in an ideal position to address the need for increased access to screening, brief intervention, and referral to treatment (SBIRT) for substance use disorder. This pre-post study explores the effects of SBIRT education and training among social work students from three campus environments (traditional, online, and satellite). Results demonstrated that participation in online training was related to increased levels of confidence, sense of responsibility, and practice of SBIRT and a decrease in perceived barriers. On-campus students showed the greatest post-training gains in confidence to use SBIRT. Results suggest that SBIRT education and training is beneficial for students from various backgrounds and should be included in social work students' core clinical practice curriculum.

Murphy, Gavin and Devine, Dympna
- Abstract
The "Children's School Lives" (CSL) study provides a unique opportunity to learn first-hand from school principals as part of a large national study about their sensemaking as they led in a time of crisis and change in terms of teaching and learning. Major interconnected findings include: (1) the centrality of relationships and communication between school principals, teachers and the wider school community; (2) the systemic and school-related challenges and supports for pedagogical and curriculum leadership; (3) the emotional intensity of leading during crisis and its implications for individual and collective wellbeing in schools; and (4) the value and role of collaborative practices both within the school and between the school and system, including school self-evaluation efforts to establish leadership impact, which in turn inform the principal and leadership team's sensemaking and adaptive leadership. Findings are contextualised through the responses of 11 principals from case study schools. While theoretical observations are drawn regarding sensemaking, practical suggestions are also made. A refocusing on the particular supports and challenges for school leadership learning and development in contexts of crisis and change is also warranted and problems and possibilities are discussed in this regard.

Margherio, Cara, Horner-Devine, M. Claire, Mizumori, Sheri J. Y., and Yen, Joyce W.
- Abstract
This qualitative study analyzes the relationship between two concepts from critical race theory -- counterspaces and community cultural wealth. Counterspaces are supportive, identity-affirming community spaces, while community cultural wealth highlights the importance of the knowledge, skills, and networks used by individuals belonging to marginalized groups to successfully navigate academia. This study investigates the hypothesis that the processes operating within counterspaces serve to strengthen an individual's access to their community cultural wealth. The study site is BRAINS, a U.S.-based professional development program for early-career academic neuroscientists from underrepresented groups. Findings revealed that two types of counterspace processes (narrative identity work and direct relational transactions) and three types of community cultural wealth (aspirational capital, social capital, and navigational capital) are most salient within BRAINS. After examining the complex interactions connecting counterspace processes and community cultural wealth, we offer recommendations for future professional development programs and research designed to broaden participation in academia.

- Abstract
This study examined the development of caregiver mind-mindedness--defined as the propensity to see one's child as an agent with an independent mind--across the first 1,000 days of life. At four timepoints (i.e., third trimester of pregnancy, 4, 14, and 24 months postpartum), 384 first-time mothers (M[subscript age] = 32.55, SD = 3.63 years) and fathers (M[subscript age] = 33.96, SD = 4.40 years) gave 5-minute speech samples about their infant that were coded for mind-mindedness (Meins & Fernyhough, 2015). Reflecting the local population, the 192 heterosexual couples were highly educated (84.6% of mothers, 77.1% of fathers had a degree) and ethnically homogenous (92.7% of mothers, 94.8% of fathers identified as White British). Results showed significant variability in mind mindedness within both expectant mothers and expectant fathers, with no mean group difference. Auto-regressive models demonstrated modest positive associations between prenatal and postnatal mind-mindedness. Latent change score models showed gains in mean mind-mindedness over time that, on average, were stronger for mothers than for fathers. For fathers, gains in mind-mindedness were positively associated with having an infant daughter and infant surgency. For mothers, higher socioeconomic status and more equal childcare were associated with greater gains in mind-mindedness across toddlerhood. Within-couple associations were evident for changes in mind-mindedness, but not for initial (prenatal) scores. We apply the relational account of mind-mindedness to frame our discussion of these findings that, by highlighting both developmental stability and change in mind-mindedness, suggest fruitful avenues for future research.

- Abstract
Schools have a duty of care to children that extends beyond educational performance to include wellbeing and welfare. Yet, research has highlighted the tensions that arise when 'care' and 'learning' are treated as binaries, especially when schools operate within unequal socio-economic conditions. Extended COVID-19 school closures brought these issues into sharp relief, highlighting the central role of schools as a front line service in the lives of poorer children. This paper provides qualitative insights into the classed experiences of extended school closure and the role and response of schools through the eyes of parents, teachers and principals in Ireland. We frame these responses in the context of the provision of a careful education, exploring the role of normative and affective relations in teaching and learning. Questions are posed in relation to schools as care regimes and the 'mission creep' between educational and welfare provision in schools serving poorer children.

- Abstract
In spite of widespread initiatives to improve access to education for girls, substantive concerns remain. While there is a rich and growing body of literature on gendered experiences of school in majority world contexts, absent is a focus on how this intersects with children's out of school lives. Further, research with children in rural communities is limited, including those who are in the earlier years of their schooling. This paper addresses these gaps, focusing on gendered dynamics in the everyday lives of children in five rural communities in Northern Sierra Leone. Drawing on Bourdieu, it explores the dialectical interplay between gendered and generational structures, understood as the gendered habitus, in a wider context of structural poverty, uneven and fragile post-colonial restructuring and development. This sets the groundwork for children's gendered dis/positioning, and ultimately capacity to engage with schooling.

Tamara DeVine Rinehart
- Abstract
This multi-case study explores the lives of six former preK-12 teachers and their health and well-being during and after teaching. Using the framework of self-care, the purpose of this research was to investigate how teachers' health, well-being, resilience, and other internal characteristics intersect with external factors of teaching and schools; accelerating teacher stress, burnout, and attrition. Through four of these former teachers' voices, we learn from lived experiences how already deteriorating schools and teacher working conditions were further exacerbated by the COVID-19 pandemic. The major themes revealed included the ineffectiveness and difficulty in early teaching careers; negative impacts/barriers to effective teaching and self-care; COVID impacts on teaching; school violence impacts on teaching; positive affirming experiences in post-teaching life; and finally issues/suggested policy changes. To address these negative impacts on teachers and the school community, leisure programming is presented as a pathway to personal development, to be paired alongside professional development. Opportunities for leisure, as part of a comprehensive employee health and wellness plan, are offered to fully support and sustain the whole individual, including multiple avenues for self-care.

Soil compaction is a threat to agricultural soil function due to constriction of macro- and meso-pores necessary for air and water movement and crop root elongation. Soils are most vulnerable to compaction when moist. Agricultural soils saturated from winter precipitation or from intentional flooding for groundwater recharge may limit growers’ operational access to fields. The objective of this research was to develop guidance for rain-free “time-to-trafficability” (including shallow workability—when a soil is conducive to both tillage and traffic) after deep wetting, using soil survey data, pedotransfer functions, and a hydroclimatological modeling approach. Trafficability is defined as a threshold of field capacity (θfc) at the soil surface (0–10 cm), ranging from 85% of θfc (clays and silty clays) to 95% of θfc (sands and loamy sands). The θfc threshold is guided by the soil texture plasticity index, an indicator of compaction risk. 2911 soil profiles from soil survey databases were subjected to a wetting simulation, followed by drainage and evaporation using HYDRUS-1D across 11 locations representing mean annual potential evapotranspiration (PET) quantiles from 5% to 95%, four months (January-April), and three different years, assuming no precipitation. Rain-free time-to-trafficability was greatest in fine and loamy soils during cold months (January and February). However, seasonal effects on time-to-trafficability were more pronounced in loamy soils. Non-linear predictive functions were developed for each 0–10 cm textural class to enable mapping the typical time-to-trafficability across PET gradients, revealing clear regional and temporal patterns. Model derived estimates can inform agricultural managed aquifer recharge timing decisions and subsequent risk of soil compaction. Additional research is needed for validation and to better constrain time-to-trafficability estimates for loamy and fine textured soils, which show a greater degree of uncertainty amid greater risk of compaction indicated by plasticity indices.

Graph coloring is often used in parallelizing scientific computations that run in distributed and multi-GPU environments; it identifies sets of independent data that can be updated in parallel. Many algorithms exist for graph coloring on a single GPU or in distributed memory, but to the best of our knowledge, hybrid MPI+GPU algorithms have been unexplored until this work. We present several MPI+GPU coloring approaches based on the distributed coloring algorithms of Gebremedhin et al. and the shared-memory algorithms of Deveci et al. . The on-node parallel coloring uses implementations in KokkosKernels, which provide parallelization for both multicore CPUs and GPUs. We further extend our approaches to compute distance-2 and partial distance-2 colorings, giving the first known distributed, multi-GPU algorithm for these problems. In addition, we propose a novel heuristic to reduce communication for recoloring in distributed graph coloring. Our experiments show that our approaches operate efficiently on inputs too large to fit on a single GPU and scale up to graphs with 76.7 billion edges running on 128 GPUs., Comment: Submitted to Parallel Computing

Computer Science - Computation and Language ,Computer Science - Machine Learning - Abstract
In this paper we implement and compare 7 different data augmentation strategies for the task of automatic scoring of children's ability to understand others' thoughts, feelings, and desires (or "mindreading"). We recruit in-domain experts to re-annotate augmented samples and determine to what extent each strategy preserves the original rating. We also carry out multiple experiments to measure how much each augmentation strategy improves the performance of automatic scoring systems. To determine the capabilities of automatic systems to generalize to unseen data, we create UK-MIND-20 - a new corpus of children's performance on tests of mindreading, consisting of 10,320 question-answer pairs. We obtain a new state-of-the-art performance on the MIND-CA corpus, improving macro-F1-score by 6 points. Results indicate that both the number of training examples and the quality of the augmentation strategies affect the performance of the systems. The task-specific augmentations generally outperform task-agnostic augmentations. Automatic augmentations based on vectors (GloVe, FastText) perform the worst. We find that systems trained on MIND-CA generalize well to UK-MIND-20. We demonstrate that data augmentation strategies also improve the performance on unseen data., Comment: The paper will be presented at ACL-IJCNLP 2021

BackgroundNext-generation sequencing is increasingly used in prenatal diagnosis. Targeted gene panels and exome sequencing are both available, but the comparative diagnostic yields of these approaches are not known.ObjectiveWe compared the diagnostic yield of exome sequencing with the simulated application of commercial targeted gene panels in a large cohort of fetuses with nonimmune hydrops fetalis.Study designThis was a secondary analysis of a cohort study of exome sequencing for nonimmune hydrops fetalis, in which recruitment, exome sequencing, and phenotype-driven variant analysis were completed in 127 pregnancies with features of nonimmune hydrops fetalis. An Internet search was performed to identify commercial laboratories that offer targeted gene panels for the prenatal evaluation of nonimmune hydrops fetalis or for specific disorders associated with nonimmune hydrops fetalis using the terms "non-immune hydrops fetalis," "fetal non-immune hydrops," "hydrops," "cystic hygroma," "lysosomal storage disease," "metabolic disorder," "inborn error of metabolism," "RASopathy," and "Noonan." Our primary outcome was the proportion of all genetic variants identified through exome sequencing that would have been identified if a targeted gene panel had instead been used. The secondary outcomes were the proportion of genetic variants that would have been identified by type of targeted gene panel (general nonimmune hydrops fetalis, RASopathy, or metabolic) and the percent of variants of uncertain significance that would have been identified on the panels, assuming 100% analytical sensitivity and specificity of panels for variants in the included genes.ResultsExome sequencing identified a pathogenic or likely pathogenic variant in 37 of 127 cases (29%) in a total of 29 genes. A variant of uncertain significance, strongly suspected to be associated with the phenotype, was identified in another 12 cases (9%). We identified 7 laboratories that offer 10 relevant targeted gene panels; 6 are described as RASopathy panels, 3 as nonimmune hydrops fetalis panels, and 1 as a metabolic panel. The median number of genes included on each of these panels is 22, ranging from 11 to 148. Had a nonimmune hydrops fetalis targeted gene panel been used instead of exome sequencing, 13 to 15 of the 29 genes (45%-52%) identified in our nonimmune hydrops fetalis cohort would have been sequenced, and 19 to 24 of the pathogenic variants (51%-62%) would have been detected. The yield was predicted to be the lowest with the metabolic panel (11%) and the highest with the largest nonimmune hydrops fetalis panel (62%). The largest nonimmune hydrops fetalis targeted gene panel would have had a diagnostic yield of 18% compared with 29% with exome sequencing. The exome sequencing platform used provided 30× or more coverage for all of the exons on the commercial targeted gene panels, supporting our assumption of 100% analytical sensitivity for exome sequencing.ConclusionThe broader coverage of exome sequencing for genetically heterogeneous disorders, such as nonimmune hydrops fetalis, made it a superior alternative to targeted gene panel testing.

IntroductionTumor mutational burden (TMB) and APOBEC mutational signatures are potential prognostic markers in patients with advanced urothelial carcinoma (aUC). Their utility in predicting outcomes to specific therapies in aUC warrants additional study.MethodsWe retrospectively reviewed consecutive UC cases assessed with UCSF500, an institutional assay that uses hybrid capture enrichment of target DNA to interrogate 479 common cancer genes. Hypermutated tumors (HM), defined as having TMB ≥10 mutations/Mb, were also assessed for APOBEC mutational signatures, while non-HM (NHM) tumors were not assessed due to low TMB. The logrank test was used to determine if there were differences in overall survival (OS) and progression-free survival (PFS) among patient groups of interest.ResultsAmong 75 aUC patients who had UCSF500 testing, 46 patients were evaluable for TMB, of which 19 patients (41%) had HM tumors and the rest had NHM tumors (27 patients). An additional 29 patients had unknown TMB status. Among 19 HM patients, all 16 patients who were evaluable for analysis had APOBEC signatures. HM patients (N=19) were compared with NHM patients (N=27) and had improved OS from diagnosis (125.3 months vs 35.7 months, p=0.06) but inferior OS for patients treated with chemotherapy (7.0 months vs 13.1 months, p=0.04). Patients with APOBEC (N=16) were compared with remaining 56 patients, comprised of 27 NHM patients and 29 patients with unknown TMB, showing APOBEC patients to have improved OS from diagnosis (125.3 months vs 44.5 months, p=0.05) but inferior OS for patients treated with chemotherapy (7.0 months vs 13.1 months, p=0.05). Neither APOBEC nor HM status were associated with response to immunotherapy.ConclusionsIn a large, single-institution aUC cohort assessed with UCSF500, an institutional NGS panel, HM tumors were common and all such tumors that were evaluated for mutational signature analysis had APOBEC signatures. APOBEC signatures and high TMB were prognostic of improved OS from diagnosis and both analyses also predicted inferior outcomes with chemotherapy treatment.

PurposeThere is limited payer coverage for genome sequencing (GS) relative to exome sequencing (ES) in the U.S. Our objective was to assess payers' considerations for coverage of GS versus coverage of ES and requirements payers have for coverage of GS. The study was conducted by the NIH-funded Clinical Sequencing Evidence-Generating Research Consortium (CSER).MethodsWe conducted semi-structured interviews with representatives of private payer organizations (payers, N = 12) on considerations and evidentiary and other needs for coverage of GS and ES. Data were analyzed using thematic analysis.ResultsWe described four categories of findings and solutions: demonstrated merits of GS versus ES, enhanced methods for evidence generation, consistent laboratory processes/sequencing methods, and enhanced implementation/care delivery. Payers see advantages to GS vs. ES and are open to broader GS coverage but need more proof of these advantages to consider them in coverage decision-making. Next steps include establishing evidence of benefits in specific clinical scenarios, developing quality standards, ensuring transparency of laboratory methods, developing clinical centers of excellence, and incorporating the role of genetic professionals.ConclusionBy comparing coverage considerations for GS and ES, we identified a path forward for coverage of GS. Future research should explicitly address payers' conditions for coverage.

A body of work spanning neuroscience, economics, and psychology indicates that decision-making is context-dependent, which means that the value of an option depends not only on the option in question, but also on the other options in the choice set-or the 'context'. While context effects have been observed primarily in small-scale laboratory studies with tightly constrained, artificially constructed choice sets, it remains to be determined whether these context effects take hold in real-world choice problems, where choice sets are large and decisions driven by rich histories of direct experience. Here, we investigate whether valuations are context-dependent in real-world choice by analyzing a massive restaurant rating dataset as well as two independent replication datasets which provide complementary operationalizations of restaurant choice. We find that users make fewer ratings-maximizing choices in choice sets with higher-rated options-a hallmark of context-dependent choice-and that post-choice restaurant ratings also varied systematically with the ratings of unchosen restaurants. Furthermore, in a follow-up laboratory experiment using hypothetical choice sets matched to the real-world data, we find further support for the idea that subjective valuations of restaurants are scaled in accordance with the choice context, providing corroborating evidence for a general mechanistic-level account of these effects. Taken together, our results provide a potent demonstration of context-dependent choice in real-world choice settings, manifesting both in decisions and subjective valuation of options.

In this phase I/II clinical trial, we investigated the safety and efficacy of high doses of mb-IL21 ex vivo expanded donor-derived NK cells to decrease relapse in 25 patients with myeloid malignancies receiving haploidentical stem-cell transplantation (HSCT). Three doses of donor NK cells (1 × 105-1 × 108 cells/kg/dose) were administered on days -2, +7, and +28. Results were compared with an independent contemporaneously treated case-matched cohort of 160 patients from the CIBMTR database.After a median follow-up of 24 months, the 2-year relapse rate was 4% vs. 38% (p = 0.014), and disease-free survival (DFS) was 66% vs. 44% (p = 0.1) in the cases and controls, respectively. Only one relapse occurred in the study group, in a patient with the high level of donor-specific anti-HLA antibodies (DSA) presented before transplantation. The 2-year relapse and DFS in patients without DSA was 0% vs. 40% and 72% vs. 44%, respectively with HR for DFS in controls of 2.64 (p = 0.029). NK cells in recipient blood were increased at day +30 in a dose-dependent manner compared with historical controls, and had a proliferating, mature, highly cytotoxic, NKG2C+/KIR+ phenotype.Administration of donor-derived expanded NK cells after haploidentical transplantation was safe, associated with NK cell-dominant immune reconstitution early post-transplant, preserved T-cell reconstitution, and improved relapse and DFS.

Phase 3 trials Viale-A and Viale-C evaluated health-related quality of life (HRQoL) in patients with AML unfit for intensive chemotherapy who received venetoclax (VEN) + (AZA) (Viale-A) or low-dose cytarabine (LDAC) (Viale-C) or placebo (PBO) + AZA or LDAC. Patient-reported outcomes included: EORTC QLQ-C30 global health status (GHS/QoL) and physical functioning (PF), PROMIS Cancer Fatigue Short Form 7a (Fatigue), and EQ-5D-5L health status visual analog scale (HS-VAS). Time to deterioration (TTD), defined as worsening from baseline in meaningful change thresholds (MCT) of ≥10, 5, or 7 points for GHS/QoL or PF, fatigue, and HS-VAS, respectively, was assessed; differences between groups were analyzed using Kaplan-Meier and unadjusted log-rank analyses. VEN + AZA vs PBO + AZA patients had longer TTD in GHS/QoL (P = 0.066) and fatigue (P = 0.189), and significantly longer TTD in PF (P = 0.028) and HS-VAS (P MCT in GHS/QoL. Overall, VEN may positively impact HRQoL in patients with AML ineligible for intensive chemotherapy, leading to longer preservation of functioning and overall health status.

Complex morphological traits are the product of many genes with transient or lasting developmental effects that interact in anatomical context. Mouse models are a key resource for disentangling such effects, because they offer myriad tools for manipulating the genome in a controlled environment. Unfortunately, phenotypic data are often obtained using laboratory-specific protocols, resulting in self-contained datasets that are difficult to relate to one another for larger scale analyses. To enable meta-analyses of morphological variation, particularly in the craniofacial complex and brain, we created MusMorph, a database of standardized mouse morphology data spanning numerous genotypes and developmental stages, including E10.5, E11.5, E14.5, E15.5, E18.5, and adulthood. To standardize data collection, we implemented an atlas-based phenotyping pipeline that combines techniques from image registration, deep learning, and morphometrics. Alongside stage-specific atlases, we provide aligned micro-computed tomography images, dense anatomical landmarks, and segmentations (if available) for each specimen (N = 10,056). Our workflow is open-source to encourage transparency and reproducible data collection. The MusMorph data and scripts are available on FaceBase ( www.facebase.org , https://doi.org/10.25550/3-HXMC ) and GitHub ( https://github.com/jaydevine/MusMorph ).

soil organic carbon ,soil organic matter - Abstract
The amount of soil organic matter is a critical indicator of soil health. Applying compost or manure, growing cover crops, reducing tillage, and increasing crop diversity may increase soil organic matter. However, soil organic matter can vary dramatically in different environments, regardless of management practices. This calls for a framework to recommend place-based soil health practices and evaluate their outcomes. We used a new framework that groups soil survey data into seven regions in California's Central Valley and Central Coast. These regions either have performance limitations, such as root restrictive horizons, salinity, and shrink-swell behavior, or have relatively homogeneous, coarse-to-loamy soils ideal for agriculture. These inherent conditions affect a soil's response to practices designed to improve soil health. Looking at vineyards as an example, we find significant soil organic matter contrasts between soil health regions but not among contrasting management approaches within a given region. We also show that conservation practices improve or help maintain soil health in several long-term experiments, but inherent soil properties and types of cropping systems affect outcomes.

- Abstract
Enterprising students who understand the work environment are considered more employable. It is accepted that higher-education has a responsibility to produce career-ready-graduates. Practicum experience provides a critical role in this preparation. This study describes the development and implementation of the WIL instrument and WIL experience to assess the perceived skill development of students (n=19). This research utilized three data capture points: (1) employability skills cluster matrix-self-assessment tool (ESCM-SAT); (2) industry feedback from supervisors to develop a deeper understanding of the value of WIL; (3) students used the Gibbs reflective cycle (Gibbs 1988). There were improvements in all skills clusters, main gains were in career management (p<0.01). Supervisor feedback gave direction for improvement for; communication, preparation and organization skills. Student reflection suggests career management skills were strengthened, confidence increased, as did their value of academics. The ESCM-SAT, industry feedback and student reflection were deemed a suitable combination to measure the WIL experiences from a student perspective.

- Abstract
This experimental study tested whether a professor's form of address (FOA) and email signature influenced students' perceptions of the professor's credibility, approachability, and likability. Guided by communication accommodation theory, the study investigated the likelihood that students would reciprocate a professor's FOA in email communication. Participants were randomly assigned to one of seven conditions varying by professor FOA (doctor, professor, first name) and email signature (present or not), with a signature only control condition. Results indicated students were more likely to reciprocate the FOA when an email signature was not present. Open-ended responses suggested students perceive instructors more positively when instructors specify a FOA and feel anxious and uncertain when professors do not specify a FOA.

- Abstract
There are multivariate influences on the development of children's executive function throughout the lifespan and substantial individual differences can be seen as early as when children are 1 and 2 years of age. These individual differences are moderately stable throughout early childhood, but more research is needed to better understand their origins. To some degree, individual differences in executive function are correlated between mother and child, but no research to date has examined these associations prior to when children are preschool age, nor have any studies considered the role of fathers' and mothers' executive function in tandem. Here, we use a sample of 484 families (Mothers 89.2% white; Fathers 92.5% white) in three countries (UK, USA, Netherlands) to investigate the role of each parents' executive function on the development of children's (49.7% female) executive function from 14 (M = 14.42, SD = 0.57) to 24 (M = 24.47, SD = 0.78) months, as well as parenting practices that underlie these associations. Results of structural equation models suggest stability in some--but not all--components of executive function and growing unity between components as children age. We replicate extant findings such that mothers' executive function predicts children's executive function over and above stability and extend these findings to include associations between father and child skills. We find an additive role of fathers' EF, similar in magnitude to the role of mothers' EF. Finally, for both mothers and fathers we find that sensitivity and autonomy supportive practices mediate the relations between parents' and children's executive function.

The coupling into a 2D layer at the angles near normal to the surface is negligible without the help of a metamaterial. We propose a low loss metamaterial, the dielectric structure with the nano/microholes through 2D materials that supports a resonance and enhances quantum efficiency in a wide range of incident angles., Comment: 8 pages, 4 figures

Astrophysics - Astrophysics of Galaxies - Abstract
Yellowballs (YBs) were first discovered during the Milky Way Project citizen-science initiative (MWP; Simpson et al. 2012). MWP users noticed compact, yellow regions in Spitzer Space Telescope mid-infrared (MIR) images of the Milky Way plane and asked professional astronomers to explain these "yellow balls." Follow-up work by Kerton et al. (2015) determined that YBs likely trace compact photo-dissociation regions associated with massive and intermediate-mass star formation. YBs were included as target objects in a version of the Milky Way Project launched in 2016 (Jayasinghe et al. 2016), which produced a listing of over 6000 YB locations. We have measured distances, cross-match associations, physical properties, and MIR colors of ~500 YBs within a pilot region covering the l= 30 - 40 degrees, b= +/- 1 degree region of the Galactic plane. We find 20-30% of YBs in our pilot region contain high-mass star formation capable of becoming expanding H II regions that produce MIR bubbles. A majority of YBs represent intermediate-mass star-forming regions whose placement in evolutionary diagrams suggest they are still actively accreting, and may be precursors to optically-revealed Herbig Ae/Be nebulae. Many of these intermediate-mass YBs were missed by surveys of massive star-formation tracers and thus this catalog provides information for many new sites of star formation. Future work will expand this pilot region analysis to the entire YB catalog., Comment: 24 pages, 10 figures (including two-panel Figure 8), to be published in ApJ

Physics - Optics ,Physics - Applied Physics - Abstract
Silicon photodetectors operating at near-infrared wavelengths with high-speed and high sensitivity are becoming critical for emerging applications, such as Light Detection and Ranging Systems (LIDAR), quantum communications, and medical imaging. However, such photodetectors present a bandwidth-absorption trade-off at those wavelengths that have limited their implementation. Photon trapping structures address this trade-off by enhancing the light-matter interactions, but maximizing their performance remains a challenge due to a multitude of factors influencing their design and fabrication. In this paper, strategies to improve the photon trapping effect while enhancing the speed of operation are investigated. By optimizing the design of photon trapping structures and experimentally integrated them in high-speed photodetectors, a simultaneous broadband absorption efficiency enhancement up to 1000% and a capacitance reduction of more than 50% has been achieved. Such work also allows to present empirical equations to correlate the quantum efficiency of photodetectors with the physical properties of the photon-trapping structures, material characteristics, and limitations of the fabrication technologies. The results obtained, open routes towards designing cost-effective CMOS integrated., Comment: 20 pages, 3 figures

Silicon photodiode based CMOS sensors with backside-illumination for 300 to 1000 nm wavelength range were studied. We showed that a single hole in the photodiode increases the optical efficiency of the pixel. In near-infrared wavelengths, the enhancement allows 70% absorption in a 3 microns thick Si. It is 4x better than for the flat pixel. We compared different shapes and sizes of single holes and holes arrays. We have shown that a certain size and shape in single holes pronounce better optical efficiency enhancement. The crosstalk was successfully reduced with trenches between pixels. We optimized the trenches to achieve minimal pixel separation for 1.12 microns pixel., Comment: 13 pages, 4 figures, and 2 tables

An irradiation campaign was conducted to provide guidance in the selection of materials and components for the radiation hardening of LED lights for use in CERN accelerator tunnels. This work describes the effects of gamma-rays on commercial-grade borosilicate, fused quartz, polymethylmethacrylate, and polycarbonate samples up to doses of 100 kGy, to qualify their use as optical materials in rad-hard LED-based luminaires. In addition, a Si bridge rectifier and a SiC Junction Barrier Schottky diode for use in power supplies of rad-hard LED lighting systems are tested using 24 GeV/c protons. The physical degradation mechanisms are discussed for each element.

Condensed Matter - Superconductivity ,Condensed Matter - Mesoscale and Nanoscale Physics - Abstract
An inhomogeneous magnetic exchange field at a superconductor/ferromagnet interface converts spin-singlet Cooper pairs to a spin-aligned (i.e. spin-polarized) triplet state. Although the decay envelope of such triplet pairs within ferromagnetic materials is well studied, little is known about their decay in non-magnetic metals and superconductors, and in particular in the presence of spin-orbit coupling (SOC). Here we investigate devices in which triplet supercurrents are injected into the s-wave superconductor Nb. In the normal state of Nb, triplet supercurrents decay over a distance of 5 nm, which is an order of magnitude smaller than the decay of spin singlet pairs due to the SOC interacting with the spin associated with triplet pairs. In the superconducting state of Nb, triplet supercurrents are not able to couple with the singlet wavefunction and thus blocked by the absence of available equilibrium states in the singlet gap. The results offer new insight into the dynamics between s-wave singlet and s-wave triplet states., Comment: 19 pages, 5 figures

Combinatorial algorithms in general and graph algorithms in particular play a critical enabling role in numerous scientific applications. However, the irregular memory access nature of these algorithms makes them one of the hardest algorithmic kernels to implement on parallel systems. With tens of billions of hardware threads and deep memory hierarchies, the exascale computing systems in particular pose extreme challenges in scaling graph algorithms. The codesign center on combinatorial algorithms, ExaGraph, was established to design and develop methods and techniques for efficient implementation of key combinatorial (graph) algorithms chosen from a diverse set of exascale applications. Algebraic and combinatorial methods have a complementary role in the advancement of computational science and engineering, including playing an enabling role on each other. In this paper, we survey the algorithmic and software development activities performed under the auspices of ExaGraph from both a combinatorial and an algebraic perspective. In particular, we detail our recent efforts in porting the algorithms to manycore accelerator (GPU) architectures. We also provide a brief survey of the applications that have benefited from the scalable implementations of different combinatorial algorithms to enable scientific discovery at scale. We believe that several applications will benefit from the algorithmic and software tools developed by the ExaGraph team.

- Abstract
Incidental findings in research with human participants may have implications for a person's present health or future health outcomes. Current guidelines focus on methods for handling and reporting incidental findings from biological test data but incidental findings might also arise from non-biological tests. This article presents three examples in which the results from non-biological test data can be predictive of future disease and should be disclosed to research participants. It is intended to increase awareness and facilitate further discussion about the reporting of incidental findings from non-biological data.
