Applications of a Recurrence for the Bernoulli Numbers

Journal of Number Theory, 1995
The author provides an easy proof of the recurrence \[ B_m= {1\over {n(1- n^m)}} \sum^{m-1}_{k =0} n^k {m \choose k} B_k \sum^{n-1}_{j=1} j^{m-k}, \] where \(\{B_m\}\) are the Bernoulli numbers. The author uses this formula to present proofs of theorems on Bernoulli numbers due to Staudt-Clausen, Carlitz, Frobenius and Ramanujan.

Human pressure, habitat heterogeneity and species traits jointly determine the level of dark diversity in coastal fish communities

Ecography, EarlyView.
Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dark diversity – has received far less attention than observed species, even ...

A Three‐Parameter Continuum Timoshenko Beam Framework for Evaluating Higher‐Mode Effects in High‐Rise Buildings With Rotational and Translational Base Flexibility

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Higher‐mode effects can significantly amplify seismic demands in high‐rise buildings, causing unintended damage over the building height. Engineered mechanisms are introduced at the base of these structures to mitigate higher‐mode effects. Existing continuum formulations for base‐flexible buildings commonly idealize the superstructure as a ...

Probability‐Distribution‐Configurable True Random Number Generators Based on Spin‐Orbit Torque Magnetic Tunnel Junctions

Advanced Science
The incorporation of randomness into stochastic computing can provide ample opportunities for applications such as simulated annealing, non‐polynomial hard problem solving, and Bayesian neuron networks.

Water‐driven dispersible fiber electrode arrays for position‐dependent intracardiac electrophysiological recording

FlexMat, EarlyView.
Abstract Intracardiac electrophysiological recording plays an essential role in identifying abnormal cardiac electrical activity and guiding arrhythmia diagnosis and treatment planning. A key challenge for minimally invasive intracardiac electrodes is to combine reliable transvascular delivery with stable and compliant endocardial contact.

An Extension of the Hilbert's Integral Inequality

Journal of Inequalities and Applications, 2009
It is shown that an extension of the Hilbert's integral inequality can be established by introducing two parameters m   (m∈N) and λ   (λ>0).

MARS‐Diff: Guarded Residual Diffusion for Leakage‐Disciplined Probabilistic Portfolio‐Loss Forecasting

Journal of Forecasting, EarlyView.
ABSTRACT This paper develops Masked Asset–Regime Scenario Diffusion (MARS‐Diff), a leakage‐disciplined framework for probabilistic forecasting of multiday portfolio losses. The framework combines a regularized heterogeneous autoregressive model with exogenous predictors (HAR‐X) as its anchor, a train‐only masked representation of a high‐dimensional ...

Environmental benefits from carbon sequestration, canola production, and zero‐tillage adoption on Saskatchewan farms

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract Greenhouse gas emissions from crop production contribute to anthropogenic climate change, while agricultural soils also sequester atmospheric carbon. Direct measurement of soil organic carbon (SOC) is limited by high sampling costs and the vast spatial extent of farmland.

A Comprehensive Study to Compare Different Compound Representations for Predicting Carcinogenicity In Vivo

Journal of Applied Toxicology, EarlyView.
ABSTRACT Carcinogenicity evaluation is a critical component of chemical risk assessment, yet traditional in vivo testing remains time consuming, costly, and ethically challenging. Computational approaches based on machine learning offer promising alternatives, but the relative contributions of different molecular representation strategies for ...
