A Dynamic Surface Metal‐Organic Framework Electrocatalyst: Potential‐Driven Activation of Atomically Defined Au Sites for the Hydrogen Evolution Reaction

Small, EarlyView.
Operando EC‐STM reveals that an NHC‐based SMOF on Au(111), initially frozen in interconnected 1D chains, dynamically reconfigures under cathodic bias into a fluxional structure bearing undercoordinated Au sites while abstracting Au atoms from the support.

Closed-form Solutions of Third-Order Generalized Leonardo Sequences with Polynomial Input

Journal of Advances in Mathematics and Computer Science
The objective of this study is to derive closed-form solutions to third-order nonhomogeneous linear recurrence relations, referred to as generalized Leonardo-type sequences, where the input function p(n) is a polynomial. The study considers the cases in which 1 appears as a root of the characteristic equation with multiplicity r = 0,1,2,3, and for each

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Narrow band imaging‐guided diode laser ablation in recurrent low‐grade non‐muscle‐invasive bladder cancer

UroPrecision, EarlyView.
Abstract Background Low‐grade non‐muscle‐invasive bladder cancer (NMIBC) is characterized by high recurrence rates, resulting in repeated interventions and intensive surveillance. Office‐based transurethral laser ablation (TULA) performed under local anesthesia is a minimally invasive alternative to transurethral resection, and narrow band imaging (NBI)

Closed-Form Leonardo-Type Sequences in Tribonacci, Third-Order Pell and Padovan Numbers

Advances in Research
In this paper, we derive unified closed-form solutions for third-order nonhomogeneous linear recurrence relations of Leonardo-type sequences, where the input term is a polynomial. By decomposing each recurrence into homogeneous and particular components, we establish explicit formulas that depend jointly on the root multiplicity of the characteristic ...

A Family Affair: War, Agency and Female Epistolary Networks in Renaissance Italy

Gender &History, EarlyView.
ABSTRACT This article draws on the largely unexplored epistolary archive of dozens of women who were born or married into military families in northern Italy around the time of the first phase of the Italian Wars (1494–1530). Building on recent work on early modern agency, patriarchy, networks and emotional communities, the article reconstructs and ...

Sodium Diclofenac‐Loaded Drug Delivery Microspheres: Impact on Calcium Hydroxide Paste Properties and Biological Response

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated whether the incorporation of sodium diclofenac‐loaded microspheres into a calcium hydroxide paste enhances antibiofilm activity while maintaining physicochemical properties and biocompatibility. Calcium hydroxide paste, calcium hydroxide combined with sodium diclofenac, and calcium hydroxide containing sodium diclofenac ...

The economic foundations of powersharing: Evidence from Africa

American Journal of Political Science, EarlyView.
Abstract How—and with whom—do rulers share power? Existing research focuses on the strategic logic of powersharing. In this paper, we analyze its economic foundations. Powersharing is modeled as a subnational fiscal contract, in which rulers allocate political representation based on constituencies’ revenue potential. Empirically, we combine historical

Attention Based Optimization for 3D Shape Registration

Computer Graphics Forum, EarlyView.
Abstract Transformers are sequence‐to‐sequence architectures originally designed to handle structurally rigid and order‐sensitive data, such as text and images. At their core, they exploit the attention mechanism, which is permutation‐equivariant and relies on computing token‐to‐token relationships.

Explicit Formulas for Polynomial-type Particular Solutions of Generalized Leonardo-type Sequences

Asian Journal of Advanced Research and Reports
Recurrence relations provide a powerful framework for understanding numerical sequences, with applications spanning both classical and modern mathematics. In earlier work, explicit iterative formulas for polynomial-type particular solutions of generalized Leonardo-type sequences were derived.
