Nonlinear Vibration of a Nonlocal Nanobeam Resting on Fractional-Order Viscoelastic Pasternak Foundations

open access: yesFractal and Fractional, 2018
In the present study, the nonlinear vibration of a nanobeam resting on the fractional order viscoelastic Winkler–Pasternak foundation is studied using nonlocal elasticity theory.

The Relational Character of Canadian Nation‐Building Infrastructure in the 21st Century

open access: yesCanadian Public Administration, EarlyView.
Abstract Infrastructure development is central to Canada's nation‐building process. This article argues that the federal government has recalibrated its nation‐building mandate from unilateral state command to relational orchestration. Through thematic analysis of thirty‐eight policy documents related to three federal infrastructure plans (2007–2016 ...

Annual Research Review: Associations of socioeconomic status with cognitive function, language ability, and academic achievement in youth: a systematic review of mechanisms and protective factors

open access: yesJournal of Child Psychology and Psychiatry, Volume 66, Issue 4, Page 417-439, April 2025.
Low socioeconomic status (SES) is negatively associated with children's cognitive and academic performance, leading to long‐term educational and economic disparities. In particular, SES is a powerful predictor of executive function (EF), language ability, and academic achievement.

Response of an Elastic Plate on a Pasternak Foundation to a Moving Load

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1980
This paper considers the response of an elastic plate to a moving load. The plate is resting on a Pasternak foundation and the load moves uniformly with a constant velocity. The deflection of the plate is expressed in the form of integration. Combinations of the velocity and the foundation parameters yield the expression in five types of integration ...

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day

Multiplexed Nanosensors for Real‐Time Monitoring of VOC‐Mediated Signalling Response in Plants

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT To enhance crop performance, intercropping strategies leverage volatile organic compound (VOC)‐driven interactions with companion plants that constitutively emit VOCs. Despite the agricultural importance, the mechanisms and kinetics of VOC‐mediated sensory transduction in receiver plants eavesdropping on neighbouring non‐kin emitters remain ...

A Finite Element Study of the Bending Behavior of Beams Resting on Two-Parameter Elastic Foundation

open access: yesBulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2006
Although the Winkler’s model is a poor representation of the many practical subgrade or subbase materials, it is widely used in soil-structure problems for almost one and a half century.

Iron homeostasis in the annual and perennial stem zones of Arabis alpina

open access: yesPlant Biology, EarlyView.
Iron accumulates in secondary growth tissues in the perennial stem zone and is correlated with particular gene expression patterns in the perennial model plant Arabis alpina. Abstract Plants store nutrients, including the micronutrient iron, in bioavailable forms to support growth in subsequent seasons. The perennial lifestyle is preponderant in nature.

MODES OF VIBRATION OF THE BEAMS UNDER THE INFLUENCE OF DISCONTINUITY IN FOUNDATION

open access: yesFacta Universitatis. Series: Mechanical Engineering, 2014
Vibrations of the Timoshenko beams resting on the Winkler and Pasternak elastic foundation with discontinuity are investigated in this paper. A p-version finite element method that accounts for shear deformation is used.
