Two-dimensional layered materials (2DLMs) have received increasing attention for their potential in bioelectronics due to their favorable electrical, optical, and mechanical properties. The transformation of the planar structures of 2DLMs into complex 3D shapes is a key strategic step toward creating conformal biointerfaces with cells and applying them as scaffolds to simultaneously guide their growth to tissues and enable integrated bioelectronic monitoring. Using a strain-engineered self-foldable bilayer, we demonstrate the facile formation of predetermined 3D microstructures of 2DLMs with controllable curvatures, called microrolls.

Non-Hermitian Topology in Hermitian Topological Matter.

Phys Rev Lett

December 2024

University of Tokyo, Institute for Solid State Physics, Kashiwa, Chiba 277-8581, Japan.

Non-Hermiticity gives rise to distinctive topological phenomena absent in Hermitian systems. However, connection between such intrinsic non-Hermitian topology and Hermitian topology has remained largely elusive. Here, considering the bulk and boundary as an environment and system, respectively, we demonstrate that anomalous boundary states in Hermitian topological insulators exhibit non-Hermitian topology.

Integer Topological Defects Reveal Antisymmetric Forces in Active Nematics.

Phys Rev Lett

December 2024

Shanghai Jiao Tong University, School of Physics and Astronomy, Institute of Natural Sciences, Shanghai 200240, China.

Article Synopsis
  • Researchers categorize cell layers as either contractile or extensile active nematics, but recent experiments with neural progenitor cells and +1 topological defects challenge this classification.
  • The study involves a particle-level model and a continuum theory, both of which reveal that cells accumulate at the core of +1 defects, aligning with the main experimental outcome.
  • The cell accumulation is driven by two overlooked antisymmetric active forces, and the findings have implications for understanding other active nematics experiments and existing theories.

Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Management of nausea and vomiting induced by antibody-drug conjugates.

Breast Cancer

January 2025

Advanced Cancer Translational Research Institute, Showa University, 1-5-8 Hatanodai, Shinagawa-ku, Tokyo, 142-8555, Japan.

Antibody-drug conjugates (ADCs) are an emerging class of anticancer therapy that combines the specificity and long circulation half-life of monoclonal antibodies with the cytotoxic potency of the payload connected through a chemical linker. The optimal management of toxicities is crucial for improving quality of life in patients undergoing ADCs and for avoiding improper dose reductions or discontinuations. This article focuses on the characteristics and management of nausea and vomiting (NV) induced by three ADCs: trastuzumab deruxtecan (T-DXd), sacituzumab govitecan (SG), and datopotamab deruxtecan (Dato-DXd).
