‘Human Motion Segmentation via Velocity-Sensitive Dual-Side Auto-Encoder’
“Human motion segmentation (HMS) aims to segment a long human action video into a bunch of short and meaningful action clips. Existing supervised learning approaches need a large amount of training data which may be costly in real-world scenario, while most unsupervised clustering methods cannot fully explore the temporal correlations among human motions and hard to achieve promising performances. In our paper, we design a novel unsupervised framework, called Velocity-Sensitive Dual-Side Auto-Encoder (VSDA), for HMS task.” Read the paper and see the full list of authors IEEE Transactions on Image Processing.

‘Microstructural Pattern Formation During Far-From-Equilibrium Alloy Solidification’
“We introduce a new phase-field formulation of rapid alloy solidification that quantitatively incorporates nonequilibrium effects at the solid-liquid interface over a very wide range of interface velocities. Simulations identify a new dynamical instability of dendrite tip growth driven by solute trapping at velocities approaching the absolute stability limit.” Read the paper and see the full list of authors at Physical Review Letters.

Associate professor John Bai, in the D’Amore-McKim School of Business, writing with Anya Mkrtchyan from the University of Massachusetts Amherst, uses “rich microdata” from the United States Census Bureau to examine the “relative performance” of new CEOs within a company, comparing CEOs promoted internally with those who are hired externally. Ultimately, their findings “suggest that inside successors might benefit from adopting an outside perspective, demonstrating a sensitivity to change, and challenging legacies and relationships that might diminish their effectiveness.” Read “What Do Outside CEOs Really Do? Evidence from Plant-Level Data” at the Harvard Law School Forum on Corporate Governance.

Breaking through the COVID-19 virus’ shell
A result of a collaboration between labs in Northeastern University’s departments of physics and chemistry, this paper expands on our understanding of SARS-CoV-2, the virus that causes COVID-19. Using optical tweezers, researchers gained “direct measurements” of the SARS-CoV-2 nucleocapsid protein, the “N” protein. These new observations on the virus’s binding process set the stage for future attempts at disrupting the process entirely, targeting the nucleocapsid protein and striking at the virus’s interior. See the full list of authors and read their research, “Structural domains of SARS-CoV-2 nucleocapsid protein coordinate to compact long nucleic acid substrates,” in Nucleic Acids Research.

Phonological knowledge shared by signers and non-signers
In this article, professor of psychology Iris Berent, with professor Judit Gervain from the University of Padua and Université Paris Cité, argues that the knowledge of sign language and of a non-sign language can mutually inform one another. “Informed by recent findings from adults and infants,” they write, “we argue that the phonological system is partly amodal. We show that hearing infants use a shared brain network to extract phonological rules from speech and sign.” Read this discussion paper, “Speakers aren’t blank slates (with respect to sign-language phonology)!” in Cognition.

“Professor Surendra M. Gupta delivered a keynote speech titled ‘Academic Research in Reverse Supply Chains, Disassembly and Remanufacturing: A Comprehensive Overview’ at the third International Conference on Future Technologies in Manufacturing, Automation, Design & Energy (ICoFT2022) organized by NIT Puducherry, Karaikal, India. Reverse supply chain consists of a series of activities required to collect used products from consumers and reprocess them to either recover their leftover market values or dispose of them. Disassembly and Remanufacturing are important elements of reverse supply chains.”

‘Optimal Recursive Expert-Enabled Inference in Regulatory Networks’
“Accurate inference of biological systems, such as gene regulatory networks and microbial communities, is a key to a deep understanding of their underlying mechanisms. Despite several advances in the inference of regulatory networks in recent years, the existing techniques cannot incorporate expert knowledge into the inference process. … This letter models the regulatory networks using Boolean network with perturbation. We develop an expert-enabled inference method for inferring the unknown parameters of the network model using expert-acquired data.” Read the paper and see the full list of authors IEEE Transactions on Visualization and Computer Graphics.

‘Towards a Unified Drag Coefficient Formula for Quantifying Wave Energy Reduction by Salt Marshes’
“Coastal regions are susceptible to increasing flood risks amid climate change. Coastal wetlands play an important role in mitigating coastal hazards. Vegetation exerts a drag force to the flow and dampens storm surges and wind waves…. As wave height increases, highly flexible vegetation causes reduced wave attenuation, whereas relatively rigid vegetation induces increased wave attenuation. The leaf contribution to wave attenuation is highly dependent on the leaf rigidity. It is recommended that leaf properties, especially its Young’s modulus be collected in future field experiments.” Read the paper and see the full list of authors in Coastal Engineering.

A virtual home for Antarctic samples around the world
Antarctica provides a remarkable source of biodiversity and serve as “a major sink” of human-made carbon emissions. In “The Time is Right for an Antarctic Biorepository Network,” the authors, from numerous institutions around the United States, argue that there is “an extensive, largely untapped wealth of Antarctic specimens” around the world. “The majority of Antarctic biological specimens are invisible and inaccessible.” With a virtual “biorepository network of Antarctic specimens,” scientists could better address “the most critical questions in Antarctic science, [including] improving human welfare, and mitigating the impacts of climate change.” Find the paper and the full list of authors…

‘Leveraging Structure for Improved Classification of Grouped Biased Data’
“We consider semi-supervised binary classification for applications in which data points are naturally grouped (e.g., survey responses grouped by state) and the labeled data is biased (e.g., survey respondents are not representative of the population). The groups overlap in the feature space and consequently the input-output patterns are related across the groups. To model the inherent structure in such data, we assume the partition-projected class-conditional invariance across groups, defined in terms of the group-agnostic feature space.” Find the paper and the full list of authors at ArXiv.

‘Calibration of Computational Tools for Missense Variant Pathogenicity Classification’
“Recommendations from the American College of Medical Genetics and Genomics and the Association for Molecular Pathology for interpreting sequence variants specify the use of computational predictors as ‘supporting’ level of evidence for pathogenicity. … Previously, we described a probabilistic framework that quantified the strengths of evidence … within ACMG/AMP recommendations. We have extended this framework to computational predictors and introduce a new standard that converts a tool’s scores to PP3 and BP4 evidence strengths.” Read “Calibration of computational tools for missense variant pathogenicity classification and ClinGen recommendations for PP3/BP4 criteria” and see the full list of authors in AJHG.
