Dynamic analysis of FG stepped truncated conical shells surrounded by Pasternak elastic foundations [PDF]

Vietnam Journal of Mechanics, 2020
This research presents a continuous element model for solving vibration problems of FG stepped truncated conical shells having various material properties and surrounded by Pasternak foundations. Based on the First Order Shear Deformation Theory (FSDT) and the equations of the FGM conical shells, the dynamic stiffness matrix is obtained for each ...

Unraveling Suicidal Ideation and Behaviors in a Global Cohort of Individuals at Clinical High‐Risk for Psychosis: Multivariable Correlates and Subthreshold Psychotic Symptoms

Acta Psychiatrica Scandinavica, EarlyView.
ABSTRACT Introduction Suicidal ideation and behaviors (SIB) are common among individuals at clinical high risk for psychosis (CHR‐P), but their relationship with the overall clinical profile remains unclear. This study aimed to identify sociodemographic/clinical factors associated with SIB in CHR‐P individuals and to examine whether subthreshold ...

Living in the Mycelial World

Topics in Cognitive Science, EarlyView.
Abstract This manuscript documents a systematic ethnomycological analysis of ethnographic archives. Focusing on texts describing human–fungi interactions, I conduct a global, cross‐cultural review of mushroom use, covering 193 societies worldwide. The study reveals diverse mushroom‐related cultural practices, emphasizing the significance of fungi ...

Investigating the Thermomechanical Stability and Vibration of Curved Smart Sandwich Nanoplates Integrated With a Hexachiral Auxetic Core and Magneto‐Electro‐Elastic Surface Layers

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 9, September 2026.
ABSTRACT This study investigates the thermal vibration and buckling characteristics of smart sandwich nanoplates featuring a hexachiral auxetic core and piezoelectric/piezomagnetic face sheets. Utilizing the nonlocal strain gradient theory (NSGT) and a higher‐order shear deformation framework, the governing equations are derived to capture size ...

Effects of Dietary Activated Charcoal Supplementation on Performance, Egg Quality, and Bone Calcification in Laying Hens Exposed to High Fluoride

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 624-641, September 2026.
ABSTRACT The aim of the present study was to determine the effects of high dietary fluoride intake on performance, egg quality, serum biochemical parameters, bone tissue, mineral accumulation, and the expression of selected mineralisation‐related genes in laying hens, and to evaluate whether these effects could be alleviated by dietary activated ...

Calculation method for internal force and deformation of the prestressed I-beam on the elastic foundation

Frontiers in Earth Science, 2023
The elastic foundation beam theory has been widely used in civil engineering, including railway, tunnel, and building foundations. With the development of fabricated structures, more elastic foundation beams need to be prestressed.

Brittle Creep as a Mechanism for Postseismic Relaxation in Upper Crustal Dolomite Marble

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract In many locations, earthquakes in the upper crust occur in carbonate rocks, whose deformation affects aftershock sequences and postseismic relaxation. We investigate the stress relaxation process and strain evolution in Jinping dolomite marble (porosity <0.2%) subjected to multi‐stage stress ramp‐relaxation cycles under confining pressures of ...
