A Two‐Step Procedure for Generating Domestic and Asymmetric Trade Costs When Data Are Scarce

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT The practice of domestic trade cost measurement faces several challenges related to data quality, methodology and theory; but the major issue is that of data scarcity. Due to these facts, both domestic and asymmetric trade costs have been ignored despite being a feature of modern trade models.

Inefficient Frontiers: Industry‐Specific Anomalies in Frontier Markets

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT In this study we identify low‐risk anomalies affiliated with industry in frontier markets, offering valuable insights for fund managers and investors managing an internationally diversified portfolio. Utilising a two‐beta model—incorporating both market and industry betas—we reveal a distinct low‐beta anomaly with a monthly magnitude of 2.13 ...

System‐Local Axes and Metabolic Reprogramming From Health to Response in House Dust Mite‐Specific Subcutaneous Immunotherapy for Allergic Rhinitis

open access: yesiMetaMed, EarlyView.
This study delineated nasal‐plasma metabolic reprogramming in house dust mite‐allergic rhinitis (HDM‐AR) and subcutaneous immunotherapy (SCIT) response, showing compartment‐specific signatures dominated by nasal lipid‐redox and plasma nucleotide‐NAD+ axes and across the HC–HDM‐AR–SCIT response continuum, dual‑compartment metabolites exhibited ...

Addressing the Abundance Paradox Through Topology‐Guided Graph Learning for Cross‐Cohort Classification of Type 2 Diabetes

open access: yesiMetaMed, EarlyView.
By shifting from highly variable taxonomic abundance to conserved ecological network topologies, our Dual‐Stream Graph Attention Network (DS‐GAT‐CP) resolves the “abundance paradox,” enabling highly accurate and cross‐regionally robust non‐invasive screening for Type 2 Diabetes. ABSTRACT Gut microbiome‐based machine learning models for Type 2 Diabetes (

Quasi‐2D perovskite memristors: From layered structures to advanced computing applications

open access: yesInfoScience, EarlyView.
Quasi‐2D perovskites enable stable memristive switching through dimensional engineering that controls ion migration pathways. The layered structure suppresses leakage, improves environmental stability, and enables analog conductance modulation for neuromorphic computing, artificial vision, and in‐memory architectures, transforming ion migration from a ...
