- Abstract
Five different metals were oscillated against each other to assess the extent of fretting damage. They were all lubricated with the same grease and were subjected to the same pressures and vibration rates. The extent of the fretting damage was dependent upon the softness of the metals and also upon the nature of the metals in contact. Metal specimens oscillated against a like metal suffered less damage than when different metals were in contact. (Author)

Summary: Background: Obesity has been recognized as a risk factor for childhood sleep‐disordered breathing (SDB), yet it remains unclear how obesity and weight change predict the course of childhood SDB. Objective: The objective of the study is to investigate the role of body weight, upper airway abnormalities and developmental trajectories on the persistence and remission of childhood SDB in the transition to adolescence. Methods: The Penn State Child Cohort is a representative population sample of 700 children (5–12 years), of whom 421 were followed up as adolescents (12–23 years). Participants underwent a clinical history, physical examination and polysomnography at both time points. Results: Obesity and enlarged tonsils were cross‐sectionally associated with childhood SDB. Longitudinally, baseline obesity predicted the persistence of childhood SDB (OR = 3.75, 95% CI = 2.00–7.05), while weight loss predicted its remission (OR = 1.67, 95% CI = 1.11–2.50). Children with enlarged tonsils who remitted from SDB had not experienced significant weight loss and only 4.4% had undergone adeno/tonsillectomy. Body fat distribution/composition at follow‐up was similar in those who had remitted from childhood SDB as compared with those who had never experienced SDB, while those who persisted with childhood SDB showed significant android distribution and visceral adiposity at follow‐up. Conclusions: Our data support a causal role for obesity and weight loss in the chronicity and remission, respectively, of childhood SDB in the transition to adolescence and suggest that remission of SDB is related to developmental trajectories of the upper airway in a significant proportion of children. Thus, targeting childhood obesity and weight gain should be a priority in the prevention and treatment of SDB during this critical developmental period. [ABSTRACT FROM AUTHOR]

Botany ,QK1-989 - Abstract
Abstract Background Cotton fibers (produced by Gossypium species) are the premier natural fibers for textile production. The two tetraploid species, G. barbadense (Gb) and G. hirsutum (Gh), differ significantly in their fiber properties, the former having much longer, finer and stronger fibers that are highly prized. A better understanding of the genetics and underlying biological causes of these differences will aid further improvement of cotton quality through breeding and biotechnology. We evaluated an inter-specific Gh × Gb recombinant inbred line (RIL) population for fiber characteristics in 11 independent experiments under field and glasshouse conditions. Sites were located on 4 continents and 5 countries and some locations were analyzed over multiple years. Results The RIL population displayed a large variability for all major fiber traits. QTL analyses were performed on a per-site basis by composite interval mapping. Among the 651 putative QTLs (LOD > 2), 167 had a LOD exceeding permutation based thresholds. Coincidence in QTL location across data sets was assessed for the fiber trait categories strength, elongation, length, length uniformity, fineness/maturity, and color. A meta-analysis of more than a thousand putative QTLs was conducted with MetaQTL software to integrate QTL data from the RIL and 3 backcross populations (from the same parents) and to compare them with the literature. Although the global level of congruence across experiments and populations was generally moderate, the QTL clustering was possible for 30 trait x chromosome combinations (5 traits in 19 different chromosomes) where an effective co-localization of unidirectional (similar sign of additivity) QTLs from at least 5 different data sets was observed. Most consistent meta-clusters were identified for fiber color on chromosomes c6, c8 and c25, fineness on c15, and fiber length on c3. Conclusions Meta-analysis provided a reliable means of integrating phenotypic and genetic mapping data across multiple populations and environments for complex fiber traits. The consistent chromosomal regions contributing to fiber quality traits constitute good candidates for the further dissection of the genetic and genomic factors underlying important fiber characteristics, and for marker-assisted selection.

- Abstract
Objectives: This study sought to characterize temporal trends, patient-specific factors, and geographic variation associated with amputation in patients with lower-extremity peripheral artery disease (LE PAD) during the study period.Background: Amputation represents the end-stage failure for those with LE PAD, and little is known about the rates and geographic variation in the use of LE amputation.Methods: By using data from the Centers for Medicare & Medicaid Services (CMS) from January 1, 2000, to December 31, 2008, we examined national patterns of LE amputation among patients age 65 years or more with PAD. Multivariable logistic regression was used to adjust regional results for other patient demographic and clinical factors.Results: Among 2,730,742 older patients with identified PAD, the overall rate of LE amputation decreased from 7,258 per 100,000 patients with PAD to 5,790 per 100,000 (p < 0.001 for trend). Male sex, black race, diabetes mellitus, and renal disease were all independent predictors of LE amputation. The adjusted odds ratio of LE amputation per year between 2000 and 2008 was 0.95 (95% CI: 0.95-0.95, p < 0.001).Conclusions: From 2000 to 2008, LE amputation rates decreased significantly among patients with PAD. However, there remains significant patient and geographic variation in amputation rates across the United States. [ABSTRACT FROM AUTHOR]- Published

This paper presents the results from an investigation of asymmetries in speech articulation on the basis of 1,502 previously published palatograms of a wide variety of speech sounds in a range of languages. For each palatogram, the direction and degree of tongue-palate contact was quantified by means of an index capturing the degree of lateral asymmetry. The results of this investigation show that lingual asymmetry in the articulation of speech sounds is substantial: 83% of the palatograms are asymmetrical. With respect to the direction of the asymmetry it is found that the asymmetry is more often towards the left side of the palate (45%) than to the right side (38%). Further analysis reveals that there are significant differences in both the direction and the degree of the asymmetry as a function of manner and place of articulation.

- Abstract
This paper contributes data towards a phonological description of intonation in Hong Kong English (HKE), an emergent, ‘nativising’ but under-described variety of English spoken primarily as the second language of L1 Cantonese speakers. We demonstrate choice and realisation of nuclear tones for ten HKE-speaking and ten British English (BrE)-speaking university students. All speakers were recorded undertaking a storytelling task in which different nuclear tones are canonically associated with different types of utterance, e.g., yes/no question and sarcastic statement. New BrE data not only provide a point of comparison, but also demonstrate ways in which form and function of contemporary BrE prosody have changed since the textbook descriptions of the last century. Greatest disparity between the groups is found for ‘tag’ phrases such as in checking, and in the paralinguistic use of rise-fall. Production of target contours ranged from 64 to 86% for the BrE cohort, 43-71% for HKE.

- Abstract
This study examines the relative duration of the penultimate syllable vowel (PSVL) in multisyllabic Setswana words in the speech of 20 Batswana (citizens) primary school children aged 6-7 years growing up in Botswana. Setswana phonology requires the lengthening of the vowel in the penultimate syllable of multisyllabic words. The participants are 10 privately educated English medium early sequential Setswana-English bilingual children, taught full-time in English (L2) from the age of 3 years, for whom English has become dominant, and 10 Setswana monolingual children. The aim is to see whether the L2, which does not have the PSVL as a phonological pattern, has had an effect on the L1 of the bilinguals. The results show that the bilinguals do not lengthen the penultimate syllable vowel; rather, they lengthen the vowel of the final syllable. The results support the notion that extensive exposure to L2 can cause changes to the patterns of L1.

Linguistics ,Human medicine ,P1 - Abstract
Research has shown that speech articulation tends to be asymmetrical in the transverse plane of the vocal tract. A recent meta-study of previously published electropalatograms revealed that 83% of these images show asymmetrical tongue-palate contact [1].\ud \ud The present study investigated articulation asymmetry on the basis of a large number of electropalatograms acquired in a sentence-reading task at the Centre for Speech Technology Research, Edinburgh University (Mocha: Multichannel Articulatory Database). The vast majority (97.5%) of these palatograms showed some degree of left-right asymmetry, with greater contact on the left-hand side being the more common finding. Asymmetry was not strongly determined by voice or place of articulation. However, it was highly dependent on manner, with fricatives and the lateral approximant showing the greatest degree of asymmetry.\ud \ud Characterisation of articulation asymmetry could improve our understanding of the speech-production process and its relationship with both neural organisation and the anatomy of the organs of speech.

- Abstract
There is little research on stress and prominence in Bahasa Melayu (BM). Work which has been done on varieties of Malay concluded that pitch or durational differences do not contribute to the production or\ud perception of stress. This study aimed to investigate the role of intensity in the perception of stress in BM among two groups of listeners, 16 native speakers of BM and 30 of BrE, in comparison with spoken British English (BrE) and Malay Speaker English (MSE). Listeners rated 30 low-pass filtered sentences, ten from each language, indicating all syllables they perceived as stressed. Comparisons of listener identification of stress with syllable intensity yielded no statistically significant difference in the BrE and\ud MSE conditions. In the BM condition, BrE listeners rated significantly more syllables as stressed with low to mid intensity than the BM listeners. The results are discussed in terms of the contribution of intensity to perceived prominence in languages.

- Abstract
The Multidisciplinary Observatory for Study of the Arctic Climate (MOSAiC) expedition consisted of a year-long drifting survey of the Central Arctic Ocean. The ecosystems component of MOSAiC included the sampling of molecular data, with metagenomes collected from a diverse range of environments. The generation of metagenome-assembled-genomes (MAGs) from metagenomes are a starting point for genome-resolved analyses. This dataset presents a catalogue of MAGs recovered from a set of 73 samples from MOSAiC, including 2407 prokaryotic and 56 eukaryotic MAGs, as well as annotations of a near complete eukaryotic MAG using the Joint Genome Institute (JGI) annotation pipeline. The metagenomic samples are from the surface ocean, chlorophyll maximum, mesopelagic and bathypelagic, within leads and under-ice ocean, as well as melt ponds, ice ridges, and first- and second-year sea ice. This set of MAGs can be used to benchmark microbial biodiversity in the Central Arctic Ocean, compare individual strains across space and time, and to study changes in Arctic microbial communities from the winter to summer, at a genomic level., Competing Interests: Competing interests: The authors declare no competing interests., (© 2025.

- Abstract
HypothesisFoaming in diesel fuels is not well understood and leads to operational challenges. To combat deleterious effects of foaming, diesel formulations can include additives called antifoams. Existing antifoams, unfortunately, are inherently ash-generating when combusted, with unknown environmental impacts. They are prohibited in certain countries, so identifying effective alternative ash-free antifoam chemistries is needed. ExperimentsWe conduct systematic characterization of foam stabilization and antifoaming mechanisms in diesel for two different antifoams (silicone-containing & ashless chemistries). Employing a custom technique combining single-bubble/single-antifoam-droplet manipulation with white light interferometry, we also obtain mechanistic insights into foam stability and antifoam dynamics. ResultsCoalescence times from both bulk foam and single bubble experiments confirm ashless antifoams are effective at reducing foaming, demonstrating the potential of ashless antifoams. Further, we perform single-antifoam-droplet experiments and obtain direct experimental evidence revealing the elusive antifoaming mechanisms. Interestingly, the silicone-containing and ashless antifoams seemingly function via two different mechanisms: spreading and dewetting respectively. This surprising finding refutes conventional wisdom that spreading is likely the only antifoam mechanism in diesels. These results and the reported experimental framework significantly enhance the scientific understanding of non-aqueous foams and will accelerate the engineering of alternative antifoam chemistries for non-aqueous systems., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

- Abstract
Burgeoning research has shown the pervasiveness of sound symbolism, a type of iconicity, in language. However, little work looks at how individual experiences and beliefs affect sound symbolic associations. We investigate pitch associations under the Frequency Code, which links high vs low pitch to small vs large body size and female vs male gender (via sexual dimorphism), long claimed to underlie "universal" meanings like submissiveness vs dominance. While such associations appear widespread, the Frequency Code assumes ideological links, e.g., between dominance and masculinity, which differ between individuals and cultures. In Implicit Association Task experiments with English-speaking listeners, we show high pitch is implicitly associated with small size and female gender, and low with large and male, following the Frequency Code. Crucially, though, the strength of these associations varies by social factors. Associations are stronger for male voices and listeners, particularly older men, as ideologies related to the Frequency Code (linking large size, strength, and dominance) tend to be stronger for men. The association of pitch with gender is stronger than with body size, reflecting stronger gender-based stereotypes. This work shows that social experience shapes and reinforces iconic associations, with important implications for how iconic meanings develop and are processed., (© 2024 Acoustical Society of America.)

- Abstract
The North Temperate Lakes Long-Term Ecological Research (NTL-LTER) program has been extensively used to improve understanding of how aquatic ecosystems respond to environmental stressors, climate fluctuations, and human activities. Here, we report on the metagenomes of samples collected between 2000 and 2019 from Lake Mendota, a freshwater eutrophic lake within the NTL-LTER site. We utilized the distributed metagenome assembler MetaHipMer to coassemble over 10 terabases (Tbp) of data from 471 individual Illumina-sequenced metagenomes. A total of 95,523,664 contigs were assembled and binned to generate 1,894 non-redundant metagenome-assembled genomes (MAGs) with ≥50% completeness and ≤10% contamination. Phylogenomic analysis revealed that the MAGs were nearly exclusively bacterial, dominated by Pseudomonadota (Proteobacteria, N = 623) and Bacteroidota (N = 321). Nine eukaryotic MAGs were identified by eukCC with six assigned to the phylum Chlorophyta. Additionally, 6,350 high-quality viral sequences were identified by geNomad with the majority classified in the phylum Uroviricota. This expansive coassembled metagenomic dataset provides an unprecedented foundation to advance understanding of microbial communities in freshwater ecosystems and explore temporal ecosystem dynamics., (© 2024.

- Abstract
This study investigates the synchronization of manual gestures with prosody and information structure using Turkish natural speech data. Prosody has long been linked to gesture as a key driver of gesture-speech synchronization. Gesture has a hierarchical phrasal structure similar to prosody. At the lowest level, gesture has been shown to be synchronized with prosody (e.g., apexes and pitch accents). However, less is known about higher levels. Even less is known about timing relationships with information structure, though this is signaled by prosody and linked to gesture. The present study analyzed phrase synchronization in 3 hr of narrations in Turkish annotated for gesture, prosody, and information structure-topics and foci. The analysis of 515 gesture phrases showed that there was no one-to-one synchronization with intermediate phrases, but their onsets and offsets were synchronized. Moreover, information structural units, topics, and foci were closely synchronized with gesture phrase medial stroke + post-hold combinations (i.e., apical areas). In addition, iconic and metaphoric gestures were more likely to be paired with foci, and deictics with topics. Overall, the results confirm synchronization of gesture and prosody at the phrasal level and provide evidence that gesture shows a direct sensitivity to information structure. These show that speech and gesture production are more connected than assumed in existing production models., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Introduction: There is limited research examining factors impacting MOUD retention in rural settings, especially within the context of the COVID-19 pandemic. Using electronic health records data collected as part of a NIDA Clinical Trials Network study (CTN-0102), this study explored how the onset of the COVID-19 pandemic may have impacted MOUD retention in a sample of 563 rural primary care patients., Methods: Cox regression model was applied to examine if COVID-19 was related to treatment retention, controlling for demographics, clinic, insurance type, and other diagnoses. The independent variable was the number of days between the patient's first MOUD prescription date during the pre-COVID observation period (10/1/2019-3/13/2020) and the start of the COVID-19 pandemic. The dependent variable was retention on MOUD, defined as the time from the first MOUD prescription documented during the pre-COVID observation period to the first break in consecutive MOUD prescriptions (right censored at 180 days)., Results: The findings demonstrated that there was a reduced risk of a prescription break for every 10-day increase in the time from the first documented MOUD prescription to the onset of the COVID-19 pandemic (HR = 0.96, 95 % CI = 0.92-0.99; p = 0.011)., Conclusions: While the data did not include complete treatment histories to determine who was new to MOUD treatment, the findings suggest that patients whose first documented MOUD prescription in the dataset was closer to the onset of the pandemic had a greater likelihood of experiencing retention challenges. This underscores the importance for clinics to establish comprehensive contingency plans for future emergencies to ensure uninterrupted MOUD treatment and support, particularly for individuals in the early stabilization phase of their recovery., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Larissa J.

- Abstract
Secondary metabolites produced by primary producers have a wide range of functions as well as indirect effects outside the scope of their direct target. Research suggests that protease inhibitors produced by cyanobacteria influence grazing by herbivores and may also protect against parasites of cyanobacteria. In this study, we asked whether those same protease inhibitors produced by cyanobacteria could also influence the interactions of herbivores with their parasites. We used the Daphnia - Metschnikowia zooplankton host-fungal parasite system to address this question because it is well documented that cyanobacteria protease inhibitors suppress trypsin and chymotrypsin in the gut of Daphnia , and because it is known that Metschnikowia infects via the gut. We tested the hypothesis that Daphnia gut proteases are necessary for Metschnikowia spores to be released from their asci. We then also tested whether diets that decrease trypsin and chymotrypsin activity in the guts of Daphnia lead to lower levels of infection. Our results show that chymotrypsin promotes the release of the fungal spores from their asci. Moreover, a diet that strongly inhibited chymotrypsin activity in Daphnia decreased infection levels, particularly in the most susceptible Daphnia clones. Our results support the growing literature that cyanobacterial diets can be beneficial to zooplankton hosts when challenged by parasites and uncover a mechanism that contributes to the protective effect of cyanobacterial diets. Specifically, we demonstrate that host chymotrypsin enzymes promote the dehiscence of Metschnikowia spores; when cyanobacteria inhibit the activity of chymotrypsin in hosts, this most likely traps the spore inside the ascus, preventing the parasite from puncturing the gut and beginning the infection process. This study illustrates how secondary metabolites of phytoplankton can protect herbivores against their own enemies., Competing Interests: The authors declare no conflict of interest., (© 2024 The Authors.

- Abstract
Introduction: Rural primary care clinics can expand their medication treatment for opioid use disorder (MOUD) capacity by coordinating care with external telemedicine (TM) vendors specializing in addiction medicine. This study used mixed methods to identify factors that influence patient referrals from rural primary care clinics to TM vendors for MOUD., Methods: Between July/August 2020 and January/February 2021, 582 patients with OUD were identified across six primary care sites; that included 68 referred to an external TM vendor to receive MOUD. Mixed effects logistic regression identified individual and site-level factors associated with being referred to the TM vendor. Clinic providers and staff participated in in-depth interviews and focus groups to discuss their considerations for referring patients to the TM vendor., Results: Patient referrals were positively associated with local household broadband coverage (OR = 2.55, p < 0.001) and negatively associated with local population density (OR = 0.01, p = 0.003) and the number of buprenorphine prescribers in the county (OR = 0.85, p < 0.001). Clinic personnel expressed appreciation for psychiatric expertise and the flexibility to access MOUD brought by the TM vendor. Perceived concerns about TM referral included a lack of trust with external providers, uncertainty about TM service quality, workflow delays, and patients' technological and insurance challenges., Conclusion: This study revealed several clinic-level factors that may potentially influence patient referral to TM vendor services for MOUD. To facilitate the referral process and utilization of TM vendors, efforts should be made to foster open communication and trust between clinic providers and TM vendors, streamline workflows, and improve Internet access for patients., Competing Interests: Declaration of conflicting interestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Larissa J.

- Abstract
Introduction: Opioid overdose deaths are increasing rapidly in the United States. Medications for opioid use disorder (MOUD) are effective and can be delivered in primary care, but uptake has been limited in rural communities. Referral to and coordination with an external telemedicine (TM) vendor by rural primary care clinics for MOUD (TM-MOUD) may increase MOUD access for rural patients, but we know little about perspectives on this model among key stakeholders. As part of a TM-MOUD feasibility study, we explored TM-MOUD acceptability and feasibility among personnel and patients from seven rural primary care clinics and a TM-MOUD vendor., Methods: We conducted virtual interviews or focus groups with clinic administrators (n = 7 interviews), clinic primary care and behavioral health providers (8 groups, n = 30), other clinic staff (9 groups, n = 37), patients receiving MOUD (n = 16 interviews), TM-MOUD vendor staff (n = 4 interviews), and vendor-affiliated behavioral health and prescribing providers (n = 17 interviews). We asked about experiences with and acceptability of MOUD (primarily buprenorphine) and telemedicine (TM) and a TM-MOUD referral and coordination model. We conducted content analysis to identify themes and participants quantitatively rated acceptability of TM-MOUD elements on a 4-item scale., Results: Perceived benefits of vendor-based TM-MOUD included reduced logistical barriers, more privacy and less stigma, and access to services not available locally (e.g., counseling, pain management). Barriers included lack of internet or poor connectivity in patients' homes, limited communication and trust between TM-MOUD and clinic providers, and questions about the value to the clinic of TM-MOUD referral to external vendor. Acceptability ratings for TM-MOUD were generally high; they were lowest among frontline staff., Conclusions: Rural primary care clinic personnel, TM-MOUD vendor personnel, and patients generally perceived referral from primary care to a TM-MOUD vendor to hold potential for increasing access to MOUD in rural communities. Increasing TM-MOUD uptake requires buy-in and understanding among staff of the TM-MOUD workflow, TM services offered, requirements for patients, advantages over clinic-based or TM services from clinic providers, and identification of appropriate patients. Poverty, along with patient hesitation to initiate treatment, creates substantial barriers to MOUD treatment generally; insufficient internet availability creates a substantial barrier to TM-MOUD., Competing Interests: Declaration of competing interest None., (Copyright © 2023 RAND Corporation.

- Abstract
The order Sordariales is taxonomically diverse, and harbours many species with different lifestyles and large economic importance. Despite its importance, a robust genome-scale phylogeny, and associated comparative genomic analysis of the order is lacking. In this study, we examined whole-genome data from 99 Sordariales, including 52 newly sequenced genomes, and seven outgroup taxa. We inferred a comprehensive phylogeny that resolved several contentious relationships amongst families in the order, and cleared-up intrafamily relationships within the Podosporaceae. Extensive comparative genomics showed that genomes from the three largest families in the dataset (Chaetomiaceae, Podosporaceae and Sordariaceae) differ greatly in GC content, genome size, gene number, repeat percentage, evolutionary rate, and genome content affected by repeat-induced point mutations (RIP). All genomic traits showed phylogenetic signal, and ancestral state reconstruction revealed that the variation of the properties stems primarily from within-family evolution. Together, the results provide a thorough framework for understanding genome evolution in this important group of fungi., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

- Abstract
Background: Experience of stroke is associated with an increased risk for diabetes and metabolic syndrome, yet few interventions exist that have been tailored to the population's unique needs., Purpose: To examine adherence and efficacy of the Diabetes Prevention Program Group Lifestyle Balance program (DPP-GLB) modified for individuals post stroke (GLB-CVA) using a randomized controlled trial., Methods: Adults (18-85 years of age), >12 months post stroke, and body mass index ≥25 kg/m2 were included in this study. Sixty-five individuals were assigned to either the GLB-CVA intervention or a 6-month wait-list control. Participants completed the 12-month GLB-CVA intervention, with attendance and assessment of weight, anthropometric, biomarker, functional, and patient reported outcome data collected at baseline, 3, 6, and 12 months., Results: High attendance (90%) and dietary and activity tracking (71%) suggest high adherence to the 12-month GLB-CVA. Six-month randomized controlled trial data indicate significant weight loss (p = .005) in the GLB-CVA group (7.4 ± 13.6 lbs, 3.65%) compared with the wait-list control (0.1 ± 10.1 lbs, 0%), and improvements in arm circumference (p = .04), high-density lipoprotein (HDL) cholesterol (p = .028), 8-year diabetes risk (p = .011), and pain interference (p < .001). Combined 12-month data showed participants lost 10.1 ± 16.8 lbs (4.88%) and improved waist circumference (p = .001), HbA1c (3.6%), diastolic blood pressure (p < .001), pain (p = .001), social participation (p = .025), and eating practices (p = .01) and habits (p < .001)., Conclusions: Engagement in the GLB-CVA can result in weight loss and improved health for individuals who are overweight or obese following stroke. Future efforts should examine effectiveness in real-world settings and focus on knowledge translation efforts., (© Society of Behavioral Medicine 2023. All rights reserved.

- Abstract
Macrocystis pyrifera (giant kelp), is a brown macroalga of great ecological importance as a primary producer and structure-forming foundational species that provides habitat for hundreds of species. It has many commercial uses (e.g. source of alginate, fertilizer, cosmetics, feedstock). One of the limitations to exploiting giant kelp's economic potential and assisting in giant kelp conservation efforts is a lack of genomic tools like a high quality, contiguous reference genome with accurate gene annotations. Reference genomes attempt to capture the complete genomic sequence of an individual or species, and importantly provide a universal structure for comparison across a multitude of genetic experiments, both within and between species. We assembled the giant kelp genome of a haploid female gametophyte de novo using PacBio reads, then ordered contigs into chromosome level scaffolds using Hi-C. We found the giant kelp genome to be 537 MB, with a total of 35 scaffolds and 188 contigs. The assembly N50 is 13,669,674 with GC content of 50.37%. We assessed the genome completeness using BUSCO, and found giant kelp contained 94% of the BUSCO genes from the stramenopile clade. Annotation of the giant kelp genome revealed 25,919 genes. Additionally, we present genetic variation data based on 48 diploid giant kelp sporophytes from three different Southern California populations that confirms the population structure found in other studies of these populations. This work resulted in a high-quality giant kelp genome that greatly increases the genetic knowledge of this ecologically and economically vital species., (© 2023.

- Abstract
When a sentence is produced with contrastive prosodic prominence, the word that carries the prominence becomes more salient, and alternatives to that word are usually implied. In processing, this implies that focused words and their alternatives should be more strongly activated. Previous research on focus processing has primarily been confined to Germanic languages. The current paper reports on two experiments investigating the role of prosodic prominence in immediate (Experiment 1) and long-term processing (Experiment 2) of focused words and focus alternatives in Mandarin. Prosodic prominence was effective in activating focused words and their alternatives. In the memory task, this facilitation effect was only found toward the beginning of the experiment. We attribute this difference to task-related adaptive use of prosodic prominence in utterance processing. This research sheds light on whether, when, and how listeners use prosodic prominence to identify important information and to evoke alternatives during sentence comprehension.

- Abstract
Purpose: The use of telemedicine (TM) has accelerated in recent years, yet research on the implementation and effectiveness of TM-delivered medication treatment for opioid use disorder (MOUD) has been limited. This study investigated the feasibility of implementing a care coordination model involving MOUD delivered via an external TM provider for the purpose of expanding access to MOUD for patients in rural settings., Methods: The study tested a care coordination model in 6 rural primary care sites by establishing referral and coordination between the clinic and a TM company for MOUD. The intervention spanned approximately 6 months from July/August 2020 to January 2021, coinciding with the peak of the COVID-19 pandemic. Each clinic tracked patients with OUD in a registry during the intervention period. A pre-/post-intervention design (N = 6) was used to assess the clinic-level outcome as patient-days on MOUD based on patient electronic health records., Findings: All clinics implemented critical components of the intervention, with an overall TM referral rate of 11.7% among patients in the registry. Five of the 6 sites showed an increase in patient-days on MOUD during the intervention period compared to the 6-month period before the intervention (mean increase per 1,000 patients: 132 days, P = .08, Cohen's d = 0.55). The largest increases occurred in clinics that lacked MOUD capacity or had a greater number of patients initiating MOUD during the intervention period., Conclusions: To expand access to MOUD in rural settings, the care coordination model is most effective when implemented in clinics that have negligible or limited MOUD capacity., (© 2023 The Authors.
