Physical Biology of Axonal Damage

open access: yesFrontiers in Cellular Neuroscience, 2018
Excessive physical impacts to the head have direct implications on the structural integrity at the axonal level. Increasing evidence suggests that tau, an intrinsically disordered protein that stabilizes axonal microtubules, plays a critical role in the ...

Time-stretch infrared spectroscopy [PDF]

open access: yesCommunications Physics, 2019
Improving the spectral acquisition rate of broadband mid-infrared spectroscopy promises further advancements of molecular science and technology. Unlike pump-probe spectroscopy, which requires repeated measurements with different pump-probe delays ...

Ranolazine-Mediated Attenuation of Mechanoelectric Feedback in Atrial Myocyte Monolayers

open access: yesFrontiers in Physiology, 2020
BackgroundMechanical stretch increases Na+ inflow into myocytes, related to mechanisms including stretch-activated channels or Na+/H+ exchanger activation, involving Ca2+ increase that leads to changes in electrophysiological properties favoring ...

Orientation dependent elastic stress concentration at tips of slender objects translating in viscoelastic fluids [PDF]

open access: yes, 2019
Elastic stress concentration at tips of long slender objects moving in viscoelastic fluids has been observed in numerical simulations, but despite the prevalence of flagellated motion in complex fluids in many biological functions, the physics of stress ...

A dynamic stochastic model of frequency-dependent stress fiber alignment induced by cyclic stretch. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND: Actin stress fibers (SFs) are mechanosensitive structural elements that respond to forces to affect cell morphology, migration, signal transduction and cell function.

Rotation of a single acetylene molecule on Cu(001) by tunneling electrons in STM

open access: yes, 2013
We study the elementary processes behind one of the pioneering works on STM controlled reactions of single molecules [Stipe et al., Phys. Rev. Lett. 81, 1263 (1998)].

Topological optimisation of rod-stirring devices

open access: yes, 2010
There are many industrial situations where rods are used to stir a fluid, or where rods repeatedly stretch a material such as bread dough or taffy. The goal in these applications is to stretch either material lines (in a fluid) or the material itself ...

Finite Element Simulations of stretch-blow moulding with experimental validation over a broad process window [PDF]

open access: yes, 2017
Injection stretch blow moulding is a well-established method of forming thin-walled containers and has been extensively researched for numerous years. This paper is concerned with validating the finite element analysis of the free-stretch-blow process in

Azelnidipine inhibits cultured rat aortic smooth muscle cell death induced by cyclic mechanical stretch. [PDF]

open access: yesPLoS ONE, 2014
Acute aortic dissection is the most common life-threatening vascular disease, with sudden onset of severe pain and a high fatality rate. Clarifying the detailed mechanism for aortic dissection is of great significance for establishing effective ...
