Deep Learning Network‐Tailored Microenvironment Matching of 4D Bioprinting Bioactive Scaffolds for Bone Regeneration

open access: yesAdvanced Science, EarlyView.
A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.

Modified MXene Aerogel With Broadband Microwave Absorption Inspired by Melanophila Acuminata Beetle

open access: yesAdvanced Science, EarlyView.
This work introduces a novel biomimetic strategy inspired by the infrared‐sensing sensilla of the Melanophila acuminata beetle. We have designed a multi‐level aerogel, featuring a three‐dimensional carbon framework decorated with synergistic CeO2 nanoparticles and Ti3C2Tx MXene nanosheets.

Conditionally Positive Definite Functions and Their Application to Multivariate Interpolations

open access: yes, 1993
We derive integral representations for conditionally positive definite functions of various types. Using these representations, we show that certain symmetric linear combinations of translates of conditionally positive definite functions are positive ...

Data‐Driven Discovery of Unconventional Antiferromagnets

open access: yesAdvanced 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.

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

open access: yesAdvanced 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

Strictly positive definite functions on spheres

open access: yes, 2018
Neste trabalho, estudamos funções estritamente positivas definidas em esferas no espaço euclidiano m-dimensional. Tais funções podem ser usadas para resolver certos problemas de interpolação em esferas. Uma vez que as funções positivas definidas já foram

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

open access: yesAdvanced 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.

On Norm-Dependent Positive Definite Functions

open access: yesPublications 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

open access: yesAdvanced 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,
