High-Throughput in situ Root Image Segmentation Based on the Improved DeepLabv3+ Method

open access: yesFrontiers in Plant Science, 2020
The Rhizotrons method is an important means of detecting dynamic growth and development phenotypes of plant roots. However, the segmentation of root images is a critical obstacle restricting further development of this method.

Predicting Fv/Fm and evaluating cotton drought tolerance using hyperspectral and 1D-CNN

open access: yesFrontiers in Plant Science, 2022
The chlorophyll fluorescence parameter Fv/Fm is significant in abiotic plant stress. Current acquisition methods must deal with the dark adaptation of plants, which cannot achieve rapid, real-time, and high-throughput measurements.

Modulation of sensory neuron mechanotransduction by PKC- and nerve growth factor-dependent pathways [PDF]

open access: yes, 2006
Many sensations of pain are evoked by mechanical stimuli, and in inflammatory conditions, sensitivity to such stimuli is commonly increased. Here we used cultured sensory neurons as a model of the peripheral terminal to investigate the effects of ...

The Hele-Shaw asymptotics for mechanical models of tumor growth [PDF]

open access: yes, 2013
Models of tumor growth, now commonly used, present several levels of complexity, both in terms of the biomedical ingredients and the mathematical description. The simplest ones contain competition for space using purely fluid mechanical concepts. Another

Evolution of Meniscal Biomechanical Properties with Growth: An Experimental and Numerical Study

open access: yesBioengineering, 2021
The menisci of the knee are complex fibro-cartilaginous tissues that play important roles in load bearing, shock absorption, joint lubrication, and stabilization.

A convergent explicit finite difference scheme for a mechanical model for tumor growth [PDF]

open access: yes, 2015
Mechanical models for tumor growth have been used extensively in recent years for the analysis of medical observations and for the prediction of cancer evolution based on imaging analysis.

Incompressible limit of mechanical model of tumor growth with viscosity [PDF]

open access: yes, 2014
Various models of tumor growth are available in the litterature. A first class describes the evolution of the cell number density when considered as a continuous visco-elastic material with growth.

Isolating factors for the prediction of rebound after guided growth with tension band plating for the valgus deformity of the knee

open access: yesJournal of Children's Orthopaedics, 2023
Purpose: The conditions leading to growth rebound after hemiepiphysiodesis are still poorly understood. This article analyzes the radiographical outcomes after guided growth with tension band plating, using plates in idiopathic genu valgum patients and ...

A Geometric Theory of Growth Mechanics [PDF]

open access: yesJournal of Nonlinear Science, 2010
In this paper we formulate a geometric theory of the mechanics of growing solids. Bulk growth is modeled by a material manifold with an evolving metric. Time dependence of metric represents the evolution of the stress-free (natural) configuration of the body in response to changes in mass density and "shape".

A Review on Mechanics and Mechanical Properties of 2D Materials - Graphene and Beyond [PDF]

open access: yes, 2016
Since the first successful synthesis of graphene just over a decade ago, a variety of two-dimensional (2D) materials (e.g., transition metal-dichalcogenides, hexagonal boron-nitride, etc.) have been discovered.
