Spatial‐Wavelength Multiplexing Error‐Controlled Photonic Analog Computing System

Advanced Science, EarlyView.
A novel photonic integrated circuit prototype implementing the concept of general‐purpose analog computing and demonstrate its capability in radio frequency applications. The chip features a multichannel architecture and performs fully optical analog computation with frequency‐domain parallel processing. An FPGA‐based error‐correction algorithm aims to

A Perspective on Interactive Theorem Provers in Physics

Advanced Science, EarlyView.
Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Solitary Galois Extensions of Algebraic Number Fields

Journal of Number Theory, 1995
Let \(k\) be an algebraic number field. For any finite Galois extensions \(K/k\) and \(L/k\), \textit{L. Stern} [J. Number Theory 32, 203-219 (1989; Zbl 0687.12006)] has proved that the norm groups \(N_{K/k} K^ \times\) and \(N_{L/k} L^ \times\) are equal iff \(K=L\).

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Why Computational Photochemistry Is Challenging and Will Probably Remain So: A Quantum Chemist's Perspective

Advanced Science, EarlyView.
Computational Photochemistry has made great strides in recent decades, but the investigation of larger molecules remains a challenge due to the inherent dilemma between the increasing computational accuracy required as the molecule size increases and the inevitable explosion in computational effort.

Selective Targeting of Immune Checkpoints HLA‐G and CD47 Using Novel Dual Signaling Protein DSP216 Promotes Innate Anticancer Immunity

Advanced Science, EarlyView.
The inhibitory immune checkpoints HLA‐G and CD47 are expressed on certain tumor types and inhibit immune cells in the tumor microenvironment. DSP216 binds specifically to cancer cells expressing both HLA‐G and CD47, and blocks their inhibitory signaling.

Elementary Abelianp-extensions of algebraic function fields

Manuscripta Mathematica, 1991
Let \(K\) be a field of characteristic \(p >0\), and let \(F/K\) be an algebraic function field. If \(E/F\) is an elementary abelian Galois extension with Galois group of order \(p^ n\) then \(E\) can be generated over \(F\) by an element \(y\) whose minimal polynomial is of the form \(T^{p^ n}-T-y\).
