Expanded Scorpionate and Siderophore‐Inspired Ligands: From Foundational Designs to Modern Applications

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The concept of scorpionate ligands has evolved significantly since the introduction of tris(pyrazolyl)borate. By integrating a biological supramolecular ligand scaffold with the classic scorpionate architecture, researchers have made notable strides in mimicking the active sites of nitrogenase and advancing homogeneous catalysis.

Runge approximation on convex sets implies the Oka property

open access: yes, 2005
We prove that the classical Oka property of a complex manifold Y, concerning the existence and homotopy classification of holomorphic mappings from Stein manifolds to Y, is equivalent to a Runge approximation property for holomorphic maps from compact ...

Abnormal functional connectivity patterns in temporal lobe epilepsy—An international ENIGMA‐epilepsy study

open access: yesEpilepsia Open, EarlyView.
Abstract Objectives Temporal lobe epilepsy (TLE) impacts multiple brain networks. Aberrant functional connectivity has been demonstrated in resting‐state networks (RSNs) that mediate higher brain functions in TLE. This study aimed to identify the reproducible patterns of altered functional connectivity in TLE in a large, international cohort through ...

Quadratic Hedging of American Options Under GARCH Models

open access: yesJournal of Futures Markets, EarlyView.
ABSTRACT American options are widely traded in financial markets, yet there is a scarcity of literature on hedging in incomplete markets. In this paper, we derive optimal hedging ratios and option values using Local Risk Minimization (LRM) and Global Risk Minimization (GRM) hedging strategies through dynamic programming.

Industry Portfolio Volatility Connections and Industry Portfolio Returns

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This paper tracks dynamic connections that form among daily US industry portfolio return volatilities using a Bayesian time‐varying parameter VAR model. Market participants often focus on sectors to filter vast amounts of information, and this focus results in cross‐industry return predictability. We characterise connections that form over the

Two stable gut microbiome guilds predict liver tumor class and treatment responses

open access: yesiMeta, EarlyView.
Gut microbiome alterations are linked to hepatocellular carcinoma (HCC), yet taxon‐based biomarkers often lack reproducibility. Using shotgun metagenomics from 120 resectable HCC (MT) and 76 benign hepatic tumor controls (BT), we reconstructed a stable interaction‐based Two Competing Guilds model (HCC‐TCG) comprising 142 genomes organized into two ...
