Mutual Information Estimation via Score-to-Fisher Bridge for Nonlinear Gaussian Noise Channels
We present a numerical method to evaluate mutual information (MI) in nonlinear Gaussian noise channels by using denoising score matching learning for estimating the score function of channel output. Via de Bruijn identity and the I--MMSE relation, Fisher information estimated from the learned score yields accurate estimates of MI through an integral representation of MI for a variety of priors and channel nonlinearities (e.g., elementwise nonlinearity). In this work, we propose a comprehensive …

Unified description of cuprate superconductors by fractionalized electrons emerging from integrated analyses of photoemission spectra and quasiparticle interference
Electronic structure of high-temperature superconducting cuprates is studied by analyzing experimental data independently obtained from two complementary spectroscopies, one, quasiparticle interference (QPI) measured by scanning-tunneling microscopy and the other, angle-resolved photoemission spectroscopy (ARPES) and by combining these two sets of data in a unified theoretical analysis. Through explicit calculations of experimentally measurable quantities, we show that a simple two-component fe…

Facts look different in different contexts...
Nigeria, Libya, Caspian Sea, and other oil patches in impoverished places are effectively without the concept of environmental regulation. They flare whatever wherever they want. In Nigeria the rampant theft of unrefined oil and "fire pit refining" is beyond anything done by regulated refiners in TX.
Not that we want to emulate Nigeria or Azerbaijan or Libya...

Impact of projection-induced optical selection bias on the weak lensing mass calibration of galaxy clusters
Weak gravitational lensing signals of optically identified clusters are impacted by a selection bias -- halo triaxiality and large-scale structure along the line of sight simultaneously boost the lensing signal and richness (the inferred number of galaxies associated with a cluster). As a result, a cluster sample selected by richness has a mean lensing signal higher than expected from its mean mass, and the inferred mass will be biased high. This selection bias is currently limiting the accurac…

Automated HEMT Model Construction from Datasheets via Multi-Modal Intelligence and Prior-Knowledge-Free Optimization
Parameter extraction for industry-standard device models like ASM-HEMT is crucial in circuit design workflows. However, many manufacturers do not provide such models, leaving users to build them using only datasheets. Unfortunately, datasheets lack sufficient information for standard step-by-step extraction. Moreover, manual data extraction from datasheets is highly time-consuming, and the absence of a fully automated method forces engineers to perform tedious manual work. To address this chall…

First-principles response simulation of wide-gap CdTe-DSDs for the FOXSI solar sounding rocket experiment
We have developed a wide-gap CdTe double-sided strip detector (CdTe-DSD) for the fourth and fifth flights of the Focusing Optics X-ray Solar Imager sounding rocket experiment (FOXSI-4/FOXSI-5). This detector features a 30 um strip width and a variable gap width from 30 um to 70 um, enabling position resolution finer than the strip pitch by inducing charge sharing across adjacent strip electrodes and utilizing this shared energy information for position reconstruction. However, this wide-gap con…

Forcing a unique minimum spanning tree and a unique shortest path
A forcing set $S$ in a combinatorial problem is a set of elements such that there is a unique solution that contains all the elements in $S$. An anti-forcing set is the symmetric concept: a set $S$ of elements is called an anti-forcing set if there is a unique solution disjoint from $S$. There are extensive studies on the computational complexity of finding a minimum forcing set in various combinatorial problems, and the known results indicate that many problems would be harder than their class…

Magneto-cubic and magneto-linear dependence observed in an in-plane anomalous Hall magnet
The Hall effect, particularly that arising from in-plane magnetic field, has recently emerged as a sensitive probe of quantum geometric properties in solids. Especially in trigonal systems, in-plane anomalous Hall effect (AHE) can be explicitly induced by nontrivial off-diagonal coupling between the magnetic field and the Hall vector on the principal plane. Here we elucidate multipolar dependence of the off-diagonal coupling in the in-plane AHE, by systematically measuring on the (001) principa…
