Exact and efficient calculation of Lagrange multipliers in constrained biological polymers: Proteins and nucleic acids as example cases [PDF]

, 2011
In order to accelerate molecular dynamics simulations, it is very common to impose holonomic constraints on their hardest degrees of freedom. In this way, the time step used to integrate the equations of motion can be increased, thus allowing, in ...

Optimizing Photovoltaic Soiling Loss Predictions in Louisiana: A Comparative Study of Measured and Modeled Data Using a Novel Approach

Progress in Photovoltaics: Research and Applications, Volume 33, Issue 4, Page 560-579, April 2025.
Traditional soiling models assume complete cleaning of PV panels after rain reaches a threshold, but in‐field testing shows this assumption is flawed. Improved Kimber and HSU models were developed to more accurately represent postrainfall soiling recovery, achieving RMSE reductions of up to 23% and MAPE under 1%.

Energetics of Point Defects in D0a Ag3Sn: First‐Principles Calculations

physica status solidi (b), Volume 262, Issue 3, March 2025.
The formation enthalpies of point defects in the Ag3Sn phase are determined at 0 K using density functional theory calculations. The point‐defect concentrations at 300 K are predicted using the Wagner–Schottky thermodynamic model. The AgSn antisite defect is the dominant point defect in Ag3Sn.

Definition of Complex One‐Parameter Generalized Moore–Penrose Inverses Using Differential Transformations

Computational and Mathematical Methods, Volume 2025, Issue 1, 2025.
This study presents analytical and numerical‐analytical decomposition methods for determining complex one‐parameter generalized inverse Moore–Penrose matrices. The analytical approach is based on the third Moore–Penrose condition, offering three solution options.

Cristal and Azurite: new tools for integration-by-parts reductions

, 2017
Scattering amplitudes computed at a fixed loop order, along with any other object computed in perturbative quantum field theory, can be expressed as a linear combination of a finite basis of loop integrals.

Effects of Alumina–Tantalum Hybrid Nanofragment on Engine Oil Flow Using a New Local Thermal Nonequilibrium Formulation

Complexity, Volume 2025, Issue 1, 2025.
The aim of this work is to study the alumina–tantalum/motor oil hybrid nanoliquid flow in a porous cavity subjected to a uniform magnetic field. We have used the Darcy–Bénard convection model for the momentum equation and a new local thermal nonequilibrium formulation for heat transport.

MCOA: A Multistrategy Collaborative Enhanced Crayfish Optimization Algorithm for Engineering Design and UAV Path Planning

International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.
The crayfish optimization algorithm (COA) is a recent bionic optimization technique that mimics the summer sheltering, foraging, and competitive behaviors of crayfish. Although COA has outperformed some classical metaheuristic (MH) algorithms in preliminary studies, it still manifests the shortcomings of falling into local optimal stagnation, slow ...

A New Generalization of Leonardo Sequences: Biperiodic Leonardo Sequence

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this study, we define a new type of number sequence called biperiodic Leonardo sequence by the recurrence relation Lena,b=aLen−1+Len−2+1 (for even n) and Lena,b=bLen−1+Len−2+1 (for odd n) with the initial conditions Le0a,b=Le1a,b=1. We obtained the characteristic function, generating function, and Binet’s formula for this sequence and propose a ...
