Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Existence of Weak Solutions for a Degenerate Goursat‐Type Linear Problem

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT For a generalization of the Gellerstedt operator with mixed‐type Dirichlet boundary conditions to a suitable Tricomi domain, we prove the existence and uniqueness of weak solutions of the linear problem and for a generalization of this problem.

A Computational Framework for Predicting Vibrations in the Front‐Loading Washing Machine Using Component‐Level Experiments and Mathematical Modeling

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study proposes a computational framework for developing a multibody dynamics (MBD) model to accurately predict the vibration behavior of front‐loading washing machines. The framework integrates component‐level experiments and mathematical modeling to characterize the dynamic behavior of key components, including the free‐stroke damper ...

Launch Uncertainty Analysis Under Barrel Erosion Using Experiments and Random Matrix Theory

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The effects of barrel erosion on artillery firing performance have long been a subject of concern, but its effect on launch uncertainty has yet to be investigated. This article explores the influence of barrel erosion on the interior ballistic mechanical properties and launch disturbances.

Neohypoplasticity for Sand Coupled With the Generalized Intergranular Strain Concept

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This work presents the coupling of the recently revisited advanced hypoplastic constitutive sand model called neohypoplasticity (NHP) with the more recently introduced concept of the generalized intergranular strain (GIS) to account for soil behavior due to small strains. The latter is essential for the simulation of cyclic deformations.

Exploring the Physical Properties of Novel Inorganic Perovskite AMgBr3 (A = Ga, Na, Tl)

open access: yesNano Select, EarlyView.
The band gap values of AMgBr3 (A = Na, Ga, and Tl) perovskites were calculated using various exchange‐correlation functionals such as generalized gradient approximation (GGA)‐Perdew–Burke–Ernzerhof (PBE), GGA‐PBEsol, GGA‐WC, Hybrid HSE06, and Tran–Blaha modified Becke–Johnson (TB‐mBJ) methods.
