Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract The increasing frequency of drought, heat stress and extreme precipitation is intensifying risks to agricultural systems in the Southern Slopes of the Himalaya (SSH) under climate change. Understanding crop loss responses across cropping systems is critical for regional food security.

Free Vibration and Stability of Axially Functionally Graded Tapered Euler-Bernoulli Beams
Shock and Vibration, 2011 Structural analysis of axially functionally graded tapered Euler-Bernoulli beams is studied using finite element method. A beam element is proposed which takes advantage of the shape functions of homogeneous uniform beam elements.

Improved Asymptotic Capacity Lower Bound for OFDM System with Compressed Sensing Channel Estimation for Bernoulli Gaussian Channel [PDF]
Radioengineering, 2016 We propose an improved capacity lower bound for OFDM system with compressed sensing channel estimation for Bernoulli-Gaussian channel. We improve the known capacity lower bound which is based on Lasso compressed sensing channel estimation, by replacing ...

Another simpler proof of Euler-Maclaurin summation formula by the asymptotic expansion of numerical integration [PDF]
, 2000 The Euler-Maclaurin summation formula plays an important role when we yield the correction formulas of numerical integrations or when we make the Romberg integration list.

A new trigonometric identity with applications
In this paper we obtain a new curious identity involving trigonometric functions. Namely, for any positive odd integer $n$ we prove that $$\sum_{k=1}^n(-1)^k(\cot kx)\sin k(n-k)x=\frac{1-n}2,$$ which is equivalent to the identity $$\sum_{k=1}^n(-1)^kU_{n-

Explicit Values of Bernoulli Polynomials at Rational Numbers
We give an explicit formula for the value of the Bernoulli polynomial B2k(t) when t is a rational number in the interval (0,1). When t=12,13,23,14,34,16,56 the value of B2k(t) is known explicitly.

Bernoulli matrix and its algebraic properties
, 2006 In this paper, we define the generalized Bernoulli polynomial matrix B(α)(x) and the Bernoulli matrix B. Using some properties of Bernoulli polynomials and numbers, a product formula of B(α)(x) and the inverse of B were given. It is shown that not only B(

Annales Mathematicae SilesianaeWe develop closed form expressions for various finite binomial Fibonacci and Lucas sums depending on the modulo 5 nature of the upper summation limit. Our expressions are inferred from some trigonometric identities.

The Low Energy Effective Lagrangian for Photon Interactions in Any Dimension
, 1996 The subject of low energy photon-photon scattering is considered in arbitrary-dimensional space-time and the interaction is widened to include scattering events involving an arbitrary number of photons.
