High-resolution remote sensing images (HRRSI) have important theoretical and practical value in urban planning. However, current segmentation methods often struggle with issues like blurred edges and loss of detailed information due to the intricate backgrounds and rich semantics in high-resolution remote sensing images. To tackle these challenges, this paper proposes an end-to-end attention-based Convolutional Neural Network (CNN) called Double Hybrid Attention U-Net (DHAU-Net). We designed a new Double Hybrid Attention structure consisting of dual-parallel hybrid attention modules to replace the skip connections in U-Net, which can eliminate redundant information interference and enhances the collection and utilization of important shallow features. Comprehensive experiments on the Massachusetts remote sensing building dataset and the Inria aerial image labeling dataset demonstrate that our proposed method achieves effective pixel-level building segmentation in urban remote sensing images by eliminating redundant information interference and making full use of shallow features, and improves the segmentation performance without significant time costs (approximately 15%). The evaluation metrics reveal significant results, with an accuracy rate of 0.9808, precision reaching 0.9300, an F1 score of 0.9112, a mean intersection over union (mIoU) of 0.9088, and a recall rate of 0.8932.

Automatic extraction of building contours from high-resolution images is of great significance in the fields of urban planning, demographics, and disaster assessment. Network models based on convolutional neural network (CNN) and transformer technology have been widely used for semantic segmentation of buildings from high resolution remote sensing images (HRSI). However, the fixed geometric structure and the local receptive field of the convolutional kernel are not good at global feature extraction, and the transformer technique with self-attention mechanism introduces computational redundancies and extracts local feature details poorly in the process of modeling the global contextual information. In this paper, a dual-branch fused reconstructive transformer network, DFRTNet, is proposed for efficient and accurate building extraction. In the encoder, the traditional transformer is reconfigured by designing the local and global feature extraction module (LGFE); the branch of global feature extraction (GFE) performs dynamic range attention (DRA) based on the idea of top-k attention for extracting global features; furthermore, the branch of local feature extraction (LFE) is used to obtain fine-grained features. The multilayer perceptron (MLP) is employed to efficiently fuse the local and global features. In the decoder, a simple channel attention module (CAM) is used in the up-sampling part to enhance channel dimension features. Our network achieved the best segmentation accuracy on both the WHU and Massachusetts building datasets when compared to other mainstream and state-of-the-art methods. [ABSTRACT FROM AUTHOR]

The aim of the paper is to derive minimization algorithms based on the Nesterov accelerated gradient flow [Y. Nesterov, Gradient methods for minimizing composite objective function. Core discussion paper, (2007). Available at ; Y. Nesterov, A method of solving a convex programming problem with convergence rate $ \mathcal {O}(1/k^2) $ O (1 / k 2). In Doklady Akademii Nauk, Vol. 269, Russian Academy of Sciences, 1983, pp. 543–547; Y. Nesterov, Introductory Lectures on Convex Optimization: A basic course, Kluwer Academic Publishers, Massachusetts, 2004.] to compute the ground state of nonlinear Schrödinger equations, which can potentially include a fractional laplacian term. A comparison is developed with standard gradient flow formulations showing that the Nesterov accelerated gradient flow has some interesting properties but at the same time finds also some limitations due to the nature of the problem. A few simulations are finally reported to understand the behaviour of the algorithms and open the path to further complicate questions that require more advanced studies concerning the application of the Nesterov accelerated gradient flow to nonlinear Schrödinger equations.

To meet 2050 decarbonization goals, Massachusetts will not be able to rely on carbon intensive energy sources (e.g. natural gas and gasoline) and hydrogen has been considered a replacement. To produce hydrogen without carbon emissions, renewable energy sources will be used to power electrolyzer stacks. However, renewable energy sources will also be in high demand for other energy sectors, such as automobiles and electrification. This paper estimates the amount of wind energy needed to replace natural gas with hydrogen and electrify automobiles. Comparisons are also made for a scenario in which heat pumps are used to replace natural gas. These energy sectors represent the bulk of energy consumed within Massachusetts and are of high interest to stakeholders globally. The analysis reveals the daunting amount of wind energy needed for replacement and that it is highly unlikely for hydrogen to replace natural gas in time to meet the state's climate goals.

Roadway area calculation is a novel problem in remote sensing and urban planning. This paper models this problem as a two-step problem, roadway extraction, and area calculation. Roadway extraction from satellite images is a problem that has been tackled many times before. This paper proposes a method using pixel resolution to calculate the area of the roads covered in satellite images. The proposed approach uses novel U-net and Resnet architectures called U-net++ and ResNeXt. The state-of-the-art model is combined with the proposed efficient post-processing approach to improve the overlap with ground truth labels. The performance of the proposed road extraction algorithm is evaluated on the Massachusetts dataset and it is shown that the proposed approach outperforms the existing solutions which use models from the U-net family.

We present field test results for a new spectroscopic instrument to measure atmospheric carbon dioxide (CO2) with high precision (0.02 ppm at 1 Hz) and demonstrate high stability (within 0.1 ppm over more than 8 months), without the need for hourly, daily, or even monthly calibration against high-pressure gas cylinders. The technical novelty of this instrument (ABsolute Carbon dioxide, ABC) is the spectral null method using an internal quartz reference cell with known CO2 column density. Compared to a previously described prototype, the field instrument has better stability and benefits from more precise thermal control of the optics and more accurate pressure measurements in the sample cell (at the mTorr level). The instrument has been deployed at a long-term ecological research site (the Harvard Forest, USA), where it has measured for eight months without on-site calibration and with minimal maintenance, showing drift bounds of less than 0.1 ppm. Field measurements agree well with those of another commercially available cavity ring-down CO2 instrument (Picarro G2301) run with a standard calibration protocol. This field test demonstrates that ABC is capable of performing high-accuracy, unattended, continuous field measurements with minimal use of calibration cylinders. [ABSTRACT FROM AUTHOR]

Ganem also investigated whether extra centrosomes contribute to cells' instability.

The article focuses on metastasis of cancer cells from tumors. The author, Antoine Karnoub, is a postdoctoral fellow in Robert Weinberg's laboratory at the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts. According to Robert Weinberg, owner of the laboratory, for cancer research, one has to understand how a tumor invades other tissues and metastasizes. Weinberg says that in 30% of patients with breast cancer, there are many micrometastases in their bone marrow at the time of diagnosis, but half of them never develop metastatic disease. In his study, Karnoub noticed that mesenchymal stem cells facilitated metastasis of cancer cells from tumors.

Background: Engagement is recognized as an important factor in aphasia treatment response and outcomes, yet gaps remain in our understanding of engagement and practices that promote engagement from the client perspective. Aims: The purpose of this phenomenological study was to explore how clients with aphasia experience engagement during their inpatient aphasia rehabilitation. Methods & Procedures: An interpretative phenomenological analysis approach guided the study design and analysis. Data were collected through in‐depth interviews with nine clients with aphasia, recruited through purposive sampling, during their inpatient rehabilitation admission. Analysis was completed using a variety of analytic techniques including coding, memoing, triangulation between coders and team discussion. Outcomes & Results: The analysis revealed that for clients with aphasia in the acute phrase of recovery, the rehabilitation process resembles travelling on a journey through a foreign land. Successful engagement in the journey was accomplished when one had a therapist who served as a trusted guide and was able to be a friend, invested, adaptable, a co‐creator, encouraging and dependable. Conclusions & Implications: Engagement is a dynamic, multifaceted and person‐centred process involving the client, provider and rehabilitation context. Findings from this work have implications for measuring engagement, training student clinicians to be skilled facilitators in engaging their clients and implementing person‐centred practices that promote engagement within clinical settings. WHAT THIS PAPER ADDS: What is already known on the subject: Engagement is recognized as an important factor in rehabilitation treatment response and outcomes. Prior literature suggests that the therapist plays a critical role in facilitating engagement within the client–provider relationship. Communication impairments associated with aphasia may negatively impact a client's ability to develop interpersonal connections and participate in the rehabilitation process. There is a dearth of research directly exploring the topic of engagement in aphasia rehabilitation, particularly from the perspective of clients with aphasia. Capturing the client perspective can provide novel insights regarding practices to foster and maintain engagement in aphasia rehabilitation. What this paper adds to existing knowledge: This interpretative phenomenological study revealed that for individuals with aphasia in the acute phase of recovery, the rehabilitation process resembles travelling on a sudden and foreign journey. Successful engagement in the journey was accomplished when one had a therapist who served as a 'trusted guide' and was able to be a friend, invested, adaptable, a co‐creator, encouraging and dependable. Through the client experience, engagement is seen as a dynamic, multifaceted and person‐centred process involving the client, provider and rehabilitation context. What are the potential or actual clinical implications of this work?: The current study highlights the complexity and nuance of engagement within the rehabilitation context, which has implications for measuring engagement, training student clinicians to be skilled in engaging their clients and implementing person‐centred practices that promote engagement within clinical settings. It is necessary to recognize that client and provider interactions (and thus engagement) are embedded in and influenced by the broader healthcare system. With this in mind, a patient‐centred approach to engagement in aphasia care delivery cannot be achieved through individual efforts only and may require prioritization and action at the systems level. Future work is needed to explore barriers and facilitators to enacting engagement practices, in order to develop and test strategies to support practice change. [ABSTRACT FROM AUTHOR]

The maintenance of wind farms is one of the major factors affecting their profitability. During preventive maintenance, the shutdown of wind turbines causes downtime energy losses. The selection of when and which turbines to maintain can significantly impact the overall downtime energy loss. This paper leverages a wind farm power generation model to calculate downtime energy losses during preventive maintenance for an offshore wind farm. Wake effects are considered to accurately evaluate power output under specific wind conditions. In addition to wind speed and direction, the influence of wake effects is an important factor in selecting time windows for maintenance. To minimize the overall downtime energy loss of an offshore wind farm caused by preventive maintenance, a mixed‐integer nonlinear optimization problem is formulated and solved by the genetic algorithm, which can select the optimal maintenance time windows of each turbine. Weather conditions are imposed as constraints to ensure the safety of maintenance personnel and transportation. Using the climatic data of Cape Cod, Massachusetts, the schedule of preventive maintenance is optimized for a simulated utility‐scale offshore wind farm. The optimized schedule not only reduces the annual downtime energy loss by selecting the maintenance dates when wind speed is low but also decreases the overall influence of wake effects within the farm. The portion of downtime energy loss reduced due to consideration of wake effects each year is up to approximately 0.2% of the annual wind farm energy generation across the case studies—with other stated opportunities for further profitability improvements.

Road extraction from remote sensing images is significant for urban planning, intelligent transportation, and vehicle navigation. However, it is challenging to automatically extract roads from remote sensing images because the scale difference of roads in remote sensing images varies greatly, and slender roads are difficult to identify. Moreover, the road in the image is often blocked by the shadows of trees and buildings, which results in discontinuous and incomplete extraction results. To solve the above problems, this paper proposes a multiscale feature encoding and long-range context-aware network (MECA-Net) for road extraction. MECA-Net adopts an encoder–decoder structure and contains two core modules. One is the multiscale feature encoding module, which aggregates multiscale road features to improve the recognition ability of slender roads. The other is the long-range context-aware module, which consists of the channel attention module and the strip pooling module, and is used to obtain sufficient long-range context information from the channel dimension and spatial dimension to alleviate road occlusion. Experimental results on the open DeepGlobe road dataset and Massachusetts road dataset indicate that the proposed MECA-Net outperforms the other eight mainstream networks, which verifies the effectiveness of the proposed method.

The Arthur and Elizabeth Schlesinger Library on the History of Women in America in Cambridge, Massachusetts was founded in 1943 when Radcliffe College, Cambridge, accepted the Woman's Rights Collection (WRC) . The WRC documents several woman's suffrage organizations and includes the papers of Maud Wood Park and other women active in the women rights movement. But it does not end with 1920, the year the federal suffrage amendment was ratified, and it includes the library's first labor collection, papers of Frances Perkins, U.S. Secretary of Labor, 1933-45, and the first woman in the Cabinet. Thus despite the emphasis on suffrage and women's political and legal rights, labor issues, from the beginning have been an integral part of the Schlesinger Library. At about the time the WRC arrived at Radcliffe, president Wilbur K. Jordan and Professor Arthur M. Schlesinger, of the Harvard University's history department decided to make it the centerpiece of a growing research library on women, rather than a static memorial to the suffrage movement. Soon after, in December 1945, another major labor collection arrived, the papers of Leonora O'Reilly. O'Reilly's papers make up one major series in the micropublication, "The Papers of the Women's Trade Union League and Its Principal Leaders," a project sponsored by the Schlesinger Library, edited by Edward T. James, and published by Research Publications Inc. in 1981.

Neuropsychological assessment using the Boston Process Approach (BPA) suggests that an analysis of the strategy or the process by which tasks and neuropsychological tests are completed, and the errors made during test completion convey much information regarding underlying brain and cognition and are as important as overall summary scores. Research over the last several decades employing an analysis of process and errors has been able to dissociate between dementia patients diagnosed with Alzheimer's disease, vascular dementia associated with MRI-determined white matter alterations, and Parkinson's disease; and between mild cognitive impairment subtypes. Nonetheless, BPA methods can be labor intensive to deploy. However, the recent availability of digital platforms for neuropsychological test administration and scoring now enables reliable, rapid, and objective data collection. Further, digital technology can quantify highly nuanced data previously unobtainable to define neurocognitive constructs with high accuracy. In this paper, a brief review of the BPA is provided. Studies that demonstrate how digital technology translates BPA into specific neurocognitive constructs using the Clock Drawing Test, Backward Digit Span Test, and a Digital Pointing Span Test are described. Implications for using data driven artificial intelligence-supported analytic approaches enabling the creation of more sensitive and specific detection/diagnostic algorithms for putative neurodegenerative illness are also discussed.

The purpose of this article is to add to the collective body of knowledge on student behavior and attitudes relative to the adoption of digital textbooks. The article summarizes an ongoing research project that examines past, current and evolving behavior in the classroom related to digital textbooks and school. It includes students, faculty and administrative attitudes behaviors and perceptions. This research was undertaken at the Sawyer Business School of Suffolk University in Boston, Massachusetts. Student attitudes and behavior toward their use of digital textbooks (eTextbooks) in higher education was examined in an ongoing longitudinal study over two years at Sawyer Business School, Suffolk University. Students in the class were divided into six teams. Five of the teams were assigned an eTextbook device and the sixth team was given a paper textbook for use through the semester. The digital technologies examined were: Amazon Kindle, Sony eReader Touch, Apple iPad, enTourage eDGe, and CourseSmart. Student attitudes and behaviors were examined pre and post class by survey each semester, and during the semesters through quizzes, journals and classroom discussion. Differential learning was measured between the six teams. Student attitudes and behaviors are becoming more receptive to and accepting of using digital textbooks each year. There was no significant difference in learning between the eTextbook devices teams or between them and the paper textbook team. [ABSTRACT FROM AUTHOR]

Screening of filter paper urine specimens for metabolic and transport disorders has been conducted in Massachusetts for the past few years. Disorders not identifiable by blood screening are detectable by this program. Specimens are obtained routinely by the parents on 3- to 4-week-old infants and mailed to a central laboratory. Testing is performed on discs punched directly from each specimen utilizing several methods of paper chromatography. Cystinuria, histidinemia, Hartnup disease, and iminoglycinuria (Group I) is each approximately as frequent as is phenylketonuria (PKU) in Massachusetts (1:14,219). Other disorders identified, including the hyperglycinemias, argininosuccinic aciduria, hyperlysinemia, hyperornithinemia, and the Fanconi syndrome (Group II) each has a frequency that seems to be no greater than 1:200,000 of the population. Transient abnormalities, such as tyrosinuria-tyrosyluria, generalized hyperaminoaciduria, iminoglycinuria, cystine-lysinuria, and others have been noted. Also diaper creme or fetal contamination of specimens as well as the ingestion of formulas supplemented with DL-methionine, of ampicillin, or of n-acetylcysteine may result in unusual amino acid patterns. A program such as this requires multiple testing procedures, access to proper evaluative and investigative facilities, and cooperation among the various participating groups. The total expense of this program is about $80,000 per year or approximately $1.00 per infant tested.

The HEALing Communities Study (HCS) is a large-scale multisite study testing community engagement using coalition facilitation as an approach to addressing the worsening overdose crisis. Within community engagement, community-based participatory research (CBPR) principles guide researchers on best practices for working in partnership with communities, yet these principles have not been well researched in large, complex, multisite studies. This paper uses ethnographic methods to explore how coalitions operationalized CBPR principles during early coalition formation. Two coders independently analyzed 101 ethnographies from HCS coalition meetings in eight Massachusetts communities held between November 2019 and December 2020. Themes were developed through consensus between the coders, followed by group discussions among the authorship team. We found that mutual trust, shared goals, addressing power dynamics, meeting structure, and attending to the sociopolitical community context are critical elements that can either hinder or advance the use of CBPR principles in practice. These findings provide unique suggestions for future community-engaged multisite studies, and demonstrate the importance of research teams mitigating inherent power imbalances by acknowledging and creating spaces for community ownership. The findings also highlight the value of a community engagement facilitator (CEF) role, as well as strategies like transparency, uniting over shared interests, and bringing in a wide range of stakeholders when operationalizing CBPR principles.
