The companion equations and the moyal-nahm equations [PDF]
, 2000 The first part of this thesis is concerned with the companion equations. These are equations of motion for the companion Lagrangian which is proposed to be the Lagrangian for a field theory associated with strings and branes, similar to the Klein-Gordon ...

InfoScience, EarlyView.Pseudomagnetic fields make light and sound emulate charged particles in magnetic fields, enabling magnetic‐free signal processing. This Review summarizes their origins, three implementations in two‐dimensional artificial lattices, and applications in energy localization and robust transport, guiding the design of topological integrated devices ...

Hypermultiplets and topological strings
, 2005 The c-map relates classical hypermultiplet moduli spaces in compactifications of type II strings on a Calabi-Yau threefold to vector multiplet moduli spaces via a further compactification on a circle. We give an off-shell description of the c-map in N =

Mechanical memory in aging: From adaptive sensing to pathological entrenchment
Interdisciplinary Medicine, EarlyView.Mechanical memory in aging operates through four temporal tiers, from cytoskeletal remodeling to metabolic reprogramming. Aging disrupts this cascade through three distinct decoupling patterns: sensor degradation, conduction blockade, and execution failure, leading to irreversible pathological entrenchment across multiple organ systems.

Quantum geometry of refined topological strings
, 2019 We consider branes in refined topological strings. We argue that their wavefunctions satisfy a Schrodinger equation depending on multiple times and prow this in the case where the topological string has a dual matrix model description.

Journal of Applied Toxicology, EarlyView.ABSTRACT Carcinogenicity evaluation is a critical component of chemical risk assessment, yet traditional in vivo testing remains time consuming, costly, and ethically challenging. Computational approaches based on machine learning offer promising alternatives, but the relative contributions of different molecular representation strategies for ...

Topological models of non-critical strings
, 1993 I describe the non-critical c = 1 string theory in the continuum, from the point of view of topological symmetry. The c = 1 string is first discussed in the Liouville formulation, then the topological invariance of non-critical strings is demonstrated,

The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT The instability of atherosclerotic plaques, particularly intraplaque hemorrhage (IPH), drives life‐threatening cardiovascular events, a process in which vascular smooth muscle cell (VSMC)‐derived foam cells play a significant role. We aim to identify key biomarkers associated with VSMC‐derived foam cells and IPH by analyzing data from human ...
