Stochastic Variational Methods in Generalized Hidden Semi-Markov Models to Characterize Functionality in Random Heteropolymers

Posted by klaurent July 5, 2022July 18, 2022Berkeley

Kavli Affiliate: Ting Xu | First 5 Authors: Yun Zhou, Boying Gong, Tao Jiang, Ting Xu, Haiyan Huang | Summary: Recent years have seen substantial advances in the development of biofunctional materials using synthetic polymers. The growing problem of elusive sequence-functionality relations for most biomaterials has driven researchers to seek more effective tools and analysis […]

An additive framework for kirigami design

Posted by klaurent July 5, 2022Harvard

Kavli Affiliate: L. Mahadevan | First 5 Authors: Levi H. Dudte, Gary P. T. Choi, Kaitlyn P. Becker, L. Mahadevan, | Summary: We present an additive approach for the inverse design of kirigami-based mechanical metamaterials by focusing on the empty (negative) spaces instead of the solid tiles. By considering each negative space as a four-bar […]

Dynamical Evolution of Brightest Cluster Galaxies and Their Host Clusters: Insights from IllustrisTNG

Posted by klaurent July 4, 2022MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Jubee Sohn, Margaret J. Geller, Mark Vogelsberger, Josh Borrow, | Summary: We explore the redshift evolution of the dynamical properties of massive clusters and their brightest cluster galaxies (BCGs) at $z < 2$ based on the IllustrisTNG-300 simulation. We select 270 massive clusters with $M_{200} < 10^{14}~{rm […]

Black Hole and de Sitter Microstructures from a Semiclassical Perspective

Posted by klaurent July 4, 2022Tokyo

Kavli Affiliate: Yasunori Nomura | Summary:We describe two different, but equivalent semiclassical views of black hole physics in which the equivalence principle and unitarity are both accommodated. In one, unitarity is built-in, while the black hole interior emerges only effectively as a collective phenomenon involving horizon (and possibly other) degrees of freedom. In the other, […]

Positive-Negative Equal Contrastive Loss for Semantic Segmentation

Posted by klaurent July 4, 2022Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Lingfei Xuan, Wenxuan Wang, Tianxiang Zhang, Jiangyun Li | Summary: The contextual information is critical for various computer vision tasks, previous works commonly design plug-and-play modules and structural losses to effectively extract and aggregate the global context. These methods utilize fine-label to optimize the model […]

The effect of obstacles near a silo outlet on the discharge of soft spheres

Posted by klaurent July 4, 2022Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Kirsten Harth, Dmitry Puzyrev, Ralf Stannarius, | Summary: Soft smooth particles in silo discharge show peculiar characteristics, including, for example, non-permanent clogging and intermittent flow. This paper describes a study of soft, low-frictional hydro-gel spheres in a quasi-2D silo. We enforce a more competitive behavior […]

Rotating Frame Relaxation for Magic Angle Spinning Solid State NMR, A Promising Tool for Characterizing Biopolymer Motion

Posted by klaurent July 3, 2022July 18, 2022Columbia

Kavli Affiliate: Ann McDermott | Authors: Ann E McDermott and Eric G Keeler | Summary: Magic angle spinning NMR rotating frame relaxation measurements provide a powerful experimental strategy to probe biomolecules dynamics, as is illustrated by numerous recent applications. We discuss experimental strategies for this class of experiments, with a particular focus on systems where […]

Genetic adaptation to pathogens and increased risk of inflammatory disorders in post-Neolithic Europe

Posted by klaurent July 3, 2022July 18, 2022Rockefeller

Kavli Affiliate: Jean Laurent Casanova | Authors: Gaspard Kerner, Anna-Lena Neehus, Laurent Abel, Jean-Laurent Casanova, Etienne Patin, Guillaume Laval and Lluis Quintana-Murci | Summary: Ancient genomics can directly detect human genetic adaptation to environmental cues. However, it remains unclear how pathogens have exerted selective pressures on human genome diversity across different epochs and affected present-day […]
