Superatom Distortion Induces Triferroicity and Spin Splitting in Two‐Dimensional Antiferromagnets

open access: yesAdvanced Science, EarlyView.
The incorporation of superatoms into a 2D square lattice induces symmetry breaking, thereby enabling concurrent coupling among magnetism, ferroelectricity, and ferroelasticity. This strategy achieves triferroic behavior—characterized by spin‐split antiferromagnetic ground states—and offers a viable pathway toward energy‐efficient spintronic devices ...

Esophageal hiatal hernia: A report of two cases

open access: yesThe Journal of Association of Chest Physicians
Hiatal hernia (HH) is a condition in which an intraabdominal organ herniates through the esophageal hiatus of the diaphragm. It is rare in the pediatric population due to congenital defects in the diaphragm.

Shidlovskii irreducibility

open access: yesIndagationes Mathematicae, 1994
Consider an \(n\times n\)-system of linear differential equations \(dY/dz= AY\) with \(A\in M_n (\mathbb{C} (z))\) and \(Y= (y_1, \dots, y_n)^t\) the vector of unknown locally complex analytic functions. In proving transcendence of the values of solutions at algebraic points Shidlovskij introduced the concept of (Shidlovskij) irreducibility. The system

Observation of Excitonic Instability in a Monolayer Ta2NiSe5 With Strain Disorder

open access: yesAdvanced Science, EarlyView.
Monolayer Ta2${\rm Ta}_2$NiSe5${\rm NiSe}_5$ sustains an excitonic insulating phase up to 190 K, with Raman signatures of gap opening and critical excitonic fluctuations. Thickness‐independent large gap ratios highlight strong exciton‐phonon coupling, while substrate‐induced strain disorder depresses Tc, establishing monolayer Ta2${\rm Ta}_2$NiSe5${\rm

Reaction of Proton Pump Inhibitors With Model Peptides Results in Novel Products

open access: yesJournal of Pharmacological Sciences, 2013
The proposed mechanism for proton pump inhibitors (PPIs) is that PPIs are activated at low pH to the sulfenamide form, which reacts with the sulfhydryl group of cysteine(s) at the active site of the proton pump, to produce reducible disulfide-bonded PPI ...

Single‐Atom Intercalation‐Driven Topological Ferroelectric Metal for High‐Performance Hydrogen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
Single‐atom Cu intercalation enables porous AB3 monolayers to integrate ferroelectricity, metallicity, topology, and hydrogen evolution catalysis in one platform. Switchable FE polarization modulates work function and hydrogen adsorption thermodynamics, providing an electrically controllable route to activate basal‐plane HER activity in topological ...

Giant Bulk Photovoltaic Effect in Two‐Dimensional Topological Ferroelectric Semimetal

open access: yesAdvanced Science, EarlyView.
ABSTRACT Ferroelectric (FE) metals have attracted growing interest because they combine ferroelectricity with metallic behavior and enable polarization‐controlled band topology near the Fermi level. However, the number of known ferroelectric metals is still limited.

A Novel Construction of Perfect Strict Avalanche Criterion S-box using Simple Irreducible Polynomials

open access: yesScientific Journal of Informatics, 2020
An irreducible polynomial is one of the main components in building an S-box with an algebraic technique approach. The selection of the precise irreducible polynomial will determine the quality of the S-box produced. One method for determining good S-box

An exciting Approach to Theoretical Spectroscopy

open access: yesAdvanced Science, EarlyView.
ABSTRACT Theoretical spectroscopy, and more generally, electronic‐structure theory, are powerful concepts for describing the complex many‐body interactions in materials. They cover methods from ground‐state properties to lattice excitations and light‐matter interaction, including time‐resolved variants.
