Local Chemical Gradients in a Mammalian Cortex Measured In Vivo With a Silicon Nanodialysis Mass Spectrometry Platform

open access: yesAngewandte Chemie, EarlyView.
Fluorescence image of the coronal slice of mouse brain where multiple neurochemicals have been measured in vivo with a nanodialysis platform coupled to CE‐MS to reveal strong millimeter‐scale spatial chemical gradients. Formation and maintenance of such local chemical compartments in the otherwise diffusion‐homogeneous cortex indicates strong ...

Corporate Governance and Financial Performance Nexus: Any Bidirectional Causality?

open access: yesInternational Journal of Management and Economics, 2016
Most studies on corporate governance recognize endogeneity in the nexus between corporate governance and financial performance. Little attention has, however, been paid to the direction of causality between the two phenomena, and hence the Vector Error ...

On Chiral Mesons in AdS/CFT

open access: yes, 2013
We analyze the spectra of non-chiral and chiral bifundamental mesons arising on intersecting D7-branes in $AdS_{5}\times S^{5}$. In the absence of magnetic flux on the curve of intersection, the spectrum is non-chiral, and the dual gauge theory is ...

Giant Conductivity Modulation and Chemical Neuromodulation via Proton‐Electron Coupling in a Hydrogen‐Bonded Coordination Polymer

open access: yesAdvanced Science, EarlyView.
A “de‐doping” strategy positions mixed protonic–electronic conductors (MPECs) as adaptive neuromorphic platforms with dynamically tunable transport. Co‐BAND achieves giant conductivity modulation (>106) and chemically tunable synaptic plasticity. Analogous to biological neuromodulation, solvent vapors dynamically reprogram the device's learning rules ...

Metabolism‐Based Biomarkers for Rapid Phenotypic Antibiotic Susceptibility Testing

open access: yesAdvanced Science, EarlyView.
Metabolic differences emerging after antibiotic exposure provide rapid phenotypic signals of susceptibility and resistance. This review summarizes metabolic biomarkers for rapid phenotypic AST, associated with nutrient uptake, respiratory activity, metabolic reprogramming, and enzymatic function. ABSTRACT The accelerating global crisis of antimicrobial

High oleic peanuts improve parameters leading to fatty liver development and change the microbiota in mice intestine

open access: yesFood & Nutrition Research, 2020
Background: Oleic-acid consumption can possibly prevent or delay metabolic diseases. In Israel, a Virginia-type peanut cultivar with a high content of oleic acid has been developed.

Flux-induced Soft Supersymmetry Breaking in Chiral Type IIB Orientifolds with D3/D7-Branes

open access: yes, 2004
We discuss supersymmetry breaking via 3-form fluxes in chiral supersymmetric type IIB orientifold vacua with D3- and D7-branes. After a general discussion of possible choices of fluxes allowing for stabilizing of a part of the moduli, we determine the ...

De Sitter from T-branes [PDF]

open access: yes, 2015
Hidden sector D7-branes with non-zero gauge flux are a generic feature of type IIB compactifications. A non-vanishing Fayet-Iliopoulos term induced by non-zero gauge flux leads to a T-brane configuration. Expanding the D7-brane action around this T-brane

Machine Learning‐Assisted Second‐Order Perturbation Theory for Chemical Potential Correction Toward Hubbard U Determination

open access: yesAdvanced Intelligent Discovery, EarlyView.
In this work, the Doubao large language model (LLM) is involved in the formula derivation processes for Hubbard U determination regarding the second‐order perturbations of the chemical potential. The core ML tool is optimized for physical domain knowledge, which is not limited to parameter prediction but rather serves as an interactive physical theory ...
