Simulation study on the operating characteristics of FPEG based on variable load control

Advances in Mechanical Engineering
To stabilize the operation of free-piston engine generators (FPEGs), a variable load control strategy is proposed to regulate piston motion. By dynamically adjusting the equivalent load to control the system’s total resistance, the strategy alters the ...

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

Dual‐Component Spidroin‐Based Hydrogels: A Mechanically Tunable Platform for 2D and 3D Cell Culture

Small, EarlyView.
A dual‐component recombinant spider silk hydrogel platform was developed by combining NT2RepCT with a bioactive vitronectin‐functionalized spidroin domain. The hydrogels self‐assemble under physiological conditions, exhibit tunable mechanical properties, and support 2D and 3D cell culture, providing a versatile platform for mechanobiological studies ...

A fast numerical method based on static reduction for the solution of the contact problem of the piston ring

矿业科学学报, 2017
This paper provides a fast method based on static reduction for the solution of the displacements of the piston ring's contact nodes. The nodal displacements and the corresponding nodal forces of the contact nodes are connected by the contact stiffness ...

Biodiesel Production from Hevea brasiliensis Seeds: A Systematic Review

Vietnam Journal of Chemistry, EarlyView.
ABSTRACT The Hevea brasiliensis (HB) species, also called the rubber tree, is currently cultivated worldwide for the extraction of latex, an input for rubber production. In addition, its seeds currently have few productive applications, despite their high oil content.

Fatal pediatric neck entrapment in a lift‐up storage bed: A preventable domestic asphyxial death

Journal of Forensic Sciences, EarlyView.
Abstract Bed‐related deaths are rare in forensic practice and are usually associated with falls, restraint‐related entrapment, or unsafe infant sleeping environments. Fatal mechanical asphyxia involving lift‐up storage beds is an exceptional occurrence, and the few published cases involve adult victims.

Extracellular fluid viscosity influences the mechanics and migration of MDA‐MB‐231 cells in a macromolecule‐dependent manner

The FEBS Journal, EarlyView.
Macromolecule‐dependent increases in extracellular fluid viscosity alter cell phenotype. These distinct macromolecules create different extracellular environments that modulate cell morphology and mechanoprotein expression, migration and invasion capacity, and cellular mechanical properties.

Impaired Windkessel function and proximal aortic stiffness: Linking vascular ageing to cognitive decline

Experimental Physiology, EarlyView.
Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Quantitative MRI changes in neck muscle size and composition following long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight poses several challenges to human health, including muscle loss and fat deposition. To mitigate these effects, exercise countermeasures are prescribed. This study aimed to measure neck muscle size and composition changes with long‐duration spaceflight using quantitative magnetic resonance imaging (MRI) and examine ...
