Kauffman Knot Invariant from SO(N) or Sp(N) Chern-Simons theory and the Potts Model
, 2010 The expectation value of Wilson loop operators in three-dimensional SO(N) Chern-Simons gauge theory gives a known knot invariant: the Kauffman polynomial. Here this result is derived, at the first order, via a simple variational method.

Advanced Materials Interfaces, Volume 13, Issue 2, 20 January 2026.Self‐organized silver nanoparticle networks coated with poly(1,3,5‐trivinyl‐1,3,5‐trimethyl‐cyclosiloxane) via initiated chemical vapor deposition exhibit a markedly reduced switching threshold (0.5 V vs 3 V). Time‐series analysis reveals that visible‐light illumination modulates the resistive switching activity, with blue light showing pronounced ...

Implications of Pareto Efficiency for Two-Agent (Household) Choice [PDF]
, 2009 We study when two-member household choice behavior is compatible with Pareto optimality. We ask when an external observer of household choices, who does not know the individuals' preferences, can rationalize the choices as being Pareto-optimal.

Advanced Science, Volume 13, Issue 2, 9 January 2026.A revolutionary imaging platform integrating quantitative single‐molecule photobleaching with ratiometric fluorescence probes enables high‐throughput (≈2300 individually resolvable channels) mapping of individual proton channels in a large field (≈3000 µm2), overcoming the spatial and temporal limitations of conventional electrophysiology.

High energy electromagnetic cascades in extragalactic space: physics and features
, 2016 Using the analytic modeling of the electromagnetic cascades compared with more precise numerical simulations we describe the physical properties of electromagnetic cascades developing in the universe on CMB and EBL background radiations.

Clinical Practice Guidelines for Peroral Cholangioscopy
Journal of Hepato-Biliary-Pancreatic Sciences, Volume 33, Issue 1, Page 58-71, January 2026.Nagai and colleagues present evidence‐based clinical practice guidelines developed by the Japan Biliary Association to support the use of peroral cholangioscopy. The guidelines address indications, procedural standards, diagnostic and therapeutic applications, and adverse event management, providing a practical reference for the safe and effective use ...

, 2019 We study two parameters that arise from the dichromatic number and the vertex-arboricity in the same way that the achromatic number comes from the chromatic number.
