Data‐Driven Discovery of Unconventional Antiferromagnets

Advanced Science, EarlyView.
A high‐throughput workflow that combines the physics‐informed pre‐screening, high‐throughput exchange calculations, Luttinger‐Tisza analysis and symmetry classification is established for accurate identification of unconventional antiferromagnets from the broad structural database.

The Graviton-Electron Vertex and The f⁰ Meson Decay Width

ACI Avances en Ciencias e Ingenierías, 2015
It takes three form factors to describe the graviton-electron interaction. In the limit of zero momentum transfer these form factors essentially reduce to the mass of the electron. In this article we show that under certain conditions the form factors of

alpha-POSITIVE/alpha-NEGATIVE DEFINITE FUNCTIONS ON GROUPS

, 2018
In this paper, we introduce the notions of an alpha-positive/alpha-negative definite function on a (discrete) group. We first construct the Naimark-GNS type representation associated to an alpha-positive definite function and prove the Schoenberg type ...

Unsuccessful Coupling of Weakly Coordinating Anion–Based Mg Salts and Alkoxyalkylamine Solvents for Rechargeable Mg Battery Application: Trace Water‐Driven Interfacial Failure

Advanced Science, EarlyView.
Combining recently established two ground‐breaking concepts, the adoption of WCAs and the use of alkoxyalkylamine‐based solvents in electrolyte formulations for rechargeable magnesium metal batteries, has led to unexpectedly unsuccessful electrochemical Mg plating/stripping performance. Comprehensive experimental and computational analyses revealed the

Multi‐Technique Integration Identifies O‐GlcNAc Transferase in Fibroblast‐Like Synoviocytes as a Therapeutic Target for Rheumatoid Arthritis

Advanced Science, EarlyView.
AI‑guided single‑cell transcriptomics identifies OGT as a key regulator enriched in rheumatoid arthritis fibroblast‑like synoviocytes (RA‐FLSs). Inflammatory stimuli activate the OGT–SAP130 axis, which modulates the H3K27ac/H3K27me3 balance and epigenetically silences BTG2, promoting aggressive transformation of RA‑FLSs.

Positive semi-definite matrices, exponential convexity for multiplicative majorization and related means of Cauchy's type

Journal of Numerical Analysis and Approximation Theory, 2010
In this paper, we obtain new results concerning the generalizations of additive and multiplicative majorizations by means of exponential convexity. We prove positive semi-definiteness of matrices generated by differences deduced from majorization type ...

On Norm-Dependent Positive Definite Functions

Publications of the Research Institute for Mathematical Sciences, 1990
Summary: Any norm-dependent positive definite function on an infinite dimensional normed space can be written as a superposition of \(\exp(- c\|\cdot\|^ 2)\). Conversely, for a Hilbert space, any superposition of \(\exp(-c\|\cdot\|^ 2)\) is positive definite. A norm-dependent positive definite function exists only if the norm is of cotype 2. If \(\exp(-

Upadacitinib Restrains the Pathogenic Fitness of CD4+ T Cells and Aberrant B Cell Programming in Optic Neuritis

Advanced Science, EarlyView.
Single‐cell profiling and functional perturbation reveal coordinated JAK1‐pSTAT3 downstream programs in optic neuritis, including MCL1‐dependent fitness of pathogenic CD4+ Tem cells and glycolysis‐linked, cholesterol‐sensitive B‐cell responses associated with RORA. Upadacitinib disrupts this reciprocal T‐B‐cell circuit and alleviates neuroinflammation,

Solutions for mixed states in open bosonic string theory

Physics Letters B, 2019
We describe the family of normalizable solutions in linearized open string field theory, defined by QΨ0=0 (Q is BRST charge) understood in the sense =0 for an arbitrary string field Φ.
