Jacobian Nullwerte, Periods and Symmetric Equations for Hyperelliptic Curves [PDF]

, 2006
We propose a solution to the hyperelliptic Schottky problem, based on the use of Jacobian Nullwerte and symmetric models for hyperelliptic curves.

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

Perception‐transduction‐transmission separation bionic H2S sensor

InfoScience, EarlyView.
The modular separation of biological olfactory systems boasts unparalleled efficiency in olfactory recognition. Introducing this perception‐transduction‐transmission separation design into chemiresistive gas sensors (bionic olfactory sensing) based on the heterojunction rectification effect overcomes the inherent limitations of traditional sensor ...

On integration of the Kowalevski gyrostat and the Clebsch problems

, 2004
For the Kowalevski gyrostat change of variables similar to that of the Kowalevski top is done. We establish one to one correspondence between the Kowalevski gyrostat and the Clebsch system and demonstrate that Kowalevski variables for the gyrostat ...

Bandgap Engineering of Nitrogen‐Doped Monolayer WSe2 Superlattice and its Application to Field Effect Transistor

Advanced Electronic Materials, Volume 12, Issue 5, 9 March 2026.
Random nitrogen substitution breaks translational symmetry in WSe2, creating localized impurity states near the band gap. In contrast, periodic nitrogen doping forms a superlattice, a man‐made crystal, that restores translational symmetry, broadening impurity states into dispersive sub‐bands that merge with the valence band. This enables controlled and

Schottky Algorithms: Classical meets Tropical

, 2018
We present a new perspective on the Schottky problem that links numerical computing with tropical geometry. The task is to decide whether a symmetric matrix defines a Jacobian, and, if so, to compute the curve and its canonical embedding.

Binder‐Free Self‐Standing Hard Carbon Electrodes Graphite‐Coated by PE‐CVD to Boost the Efficiency of Na‐Ion Batteries

Batteries &Supercaps, Volume 9, Issue 2, February 2026.
Binder‐free, self‐standing hard carbon electrodes (SSEs) are designed and utilized as anodes in Na‐ion batteries, demonstrating a high reversible capacity of 320 mAh g−1. Coating the SSEs with nanographite via plasma‐enhanced chemical vapor deposition limits the formation of solid electrolyte interphase, thereby improving the iCE to 92.5%.

Modular Invariant Regularization of String Determinants and the Serre GAGA Principle

, 2013
Since any string theory involves a path integration on the world-sheet metric, their partition functions are volume forms on the moduli space of genus g Riemann surfaces M_g, or on its super analog.
