C∞‐Structures for Liénard Equations and New Exact Solutions to a Class of Klein–Gordon Equations

Mathematical Methods in the Applied Sciences, Volume 49, Issue 4, Page 2795-2822, 15 March 2026.
ABSTRACT Liénard equations are analyzed using the recent theory of 𝒞∞‐structures. For each Liénard equation, a 𝒞∞‐structure is determined by using a Lie point symmetry and a 𝒞∞‐symmetry. Based on this approach, a novel method for integrating these equations is proposed, which consists in solving sequentially two completely integrable Pfaffian equations.

SiCmiR Atlas: Single‐Cell miRNA Landscape Reveals Hub‐miRNA and Network Signatures in Human Cancers

Advanced Science, Volume 13, Issue 16, 18 March 2026.
SiCmiR predicts mature miRNA activity at single‐cell resolution using only 977 landmark genes, enabling scalable reconstruction of miRNA landscapes across diverse tissues and disease contexts. The SiCmiR Atlas integrates 9.36 million cells with analytical tools for hub‐miRNA discovery, biomarker prioritization, and regulatory network interrogation ...

q-Genocchi Numbers and Polynomials Associated with q-Genocchi-Type l-Functions

Advances in Difference Equations, 2008
The main purpose of this paper is to study on generating functions of the q-Genocchi numbers and polynomials. We prove new relation for the generalized q-Genocchi numbers which is related to the q-Genocchi numbers and q-Bernoulli numbers.

Asymptotic behaviour of Bernoulli, Euler, and generalized Bernoulli polynomials

Journal of Approximation Theory, 1987
The author considers some interesting problems of the asymptotic behaviour of Bernoulli, Euler and generalized (in the Berger-Leopoldt sense) Bernoulli polynomials. In particular, it is shown that the polynomials in question can be approximated by the truncated MacLaurin series for sine and cosine (with explicit error bounds) and that the sequences of ...

Dollars for Drops: Abatement Cost of Water for Irrigation in the Colorado River Basin

Applied Economic Perspectives and Policy, Volume 48, Issue 1, Page 278-293, March 2026.
ABSTRACT The Colorado River is a lifeline for more than 40 million people in the western United States. However, with climate change diminishing snowpacks in the Rocky Mountains and increasing demands from agriculture and urban areas, the river's flow has become insufficient to meet all the competing needs.

Some congruences involving generalized Bernoulli numbers and Bernoulli polynomials

Acta Arithmetica
Let $[x]$ be the integral part of $x$, $n>1$ be a positive integer and $χ_n$ denote the trivial Dirichlet character modulo $n$. In this paper, we use an identity established by Z. H. Sun to get congruences of $T_{m,k}(n)=\sum_{x=1}^{[n/m]}\frac{χ_n(x)}{x^k}\left(\bmod n^{r+1}\right)$ for $r\in \{1,2\}$, any positive integer $m $ with $n \equiv \pm 1

Accelerated 3D MRI for ARIA monitoring in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract INTRODUCTION Amyloid‐targeting therapies for Alzheimer's disease require regular MRI monitoring for amyloid‐related imaging abnormalities (ARIA). 3D scans are more sensitive but time intensive; ultra‐fast implementations could improve access and reduce burden.

On the Symmetric Properties for the Generalized Twisted Bernoulli Polynomials

Journal of Inequalities and Applications, 2009
We study the symmetry for the generalized twisted Bernoulli polynomials and numbers. We give some interesting identities of the power sums and the generalized twisted Bernoulli polynomials using the symmetric properties for the -adic invariant integral.

Spatial capture–recapture reveals resource use and declining skipper numbers in Baltic Sea salmon trolling fisheries

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Many populations of Atlantic salmon (Salmo salar) native to the Baltic Sea are endangered. A significant group targeting salmon in this region is the recreational trolling fishery. Due to frequent changes in fisheries regulations and conditions, both salmon conservation and fishers are affected.

Experimental Design and Predictive Modeling of Hybrid Jute/Kenaf/Glass Fiber Polymer Composites With SiC Nanoparticles for Enhanced Flexural and Hardness Performance

Engineering Reports, Volume 8, Issue 3, March 2026.
Hybrid composites of jute, kenaf, and glass fibers with SiC nanoparticles were optimized using RSM and ANN. Optimal configuration improved flexural strength by 18% and hardness by 32%, demonstrating machine‐learning‐guided design for superior structural performance.
