Modeling multi-cellular systems using sub-cellular elements [PDF]

open access: yes, 2005
We introduce a model for describing the dynamics of large numbers of interacting cells. The fundamental dynamical variables in the model are sub-cellular elements, which interact with each other through phenomenological intra- and inter-cellular ...

Stem neck-shaft angle as a biomechanical prerequisite for aseptic loosening of the acetabular componen (experimental study)

open access: yesГений oртопедии, 2022
Introduction Causes of aseptic loosening of THA components and improvement of the implants remain the subject of scientific discussions. The objective was to perform comparative analysis of the results of biomechanical modeling of cementless total hip ...

A review of contemporary techniques for measuring ergonomic wear comfort of protective and sport clothing [PDF]

open access: yes, 2021
Protective and sport clothing is governed by protection requirements, performance, and comfort of the user. The comfort and impact performance of protective and sport clothing are typically subjectively measured, and this is a multifactorial and dynamic ...

Constraining Morphologies of Soft Tissues in Extinct Vertebrates Using Multibody Dynamic Simulations: A Case Study on Articular Cartilage of the Sauropod Dreadnoughtus

open access: yesFrontiers in Earth Science, 2022
Rarity of soft tissue preservation, including of articular cartilage, in the fossil record hinders creation of biologically-realistic mechanical models. Previous studies of articular cartilage in extant taxa have documented important aspects of cartilage

Form-function relationships in dragonfly mandibles under an evolutionary perspective [PDF]

open access: yes, 2017
© 2017 The Author(s). Functional requirements may constrain phenotypic diversification or foster it. For insect mouthparts, the quantification of the relationship between shape and function in an evolutionary framework remained largely unexplored.

Fatigue evaluation in maintenance and assembly operations by digital human simulation [PDF]

open access: yes, 2010
Virtual human techniques have been used a lot in industrial design in order to consider human factors and ergonomics as early as possible. The physical status (the physical capacity of virtual human) has been mostly treated as invariable in the current ...
