Mechanisms and mechanics of auditory masking

open access: yesThe Journal of Physiology, 2013
It is rare to hear just one sound at a time. More often than not, our experience of listening to someone speak, or hearing a piece of music, is made more challenging, and possibly more annoying, by the presence of interfering sound, be it traffic noise, air-conditioning rumble, or other people talking at the same time. In extreme situations, such as in

Mechanisms of Teratogenesis [PDF]

open access: yesAmerican Journal of Anatomy, 1972
Man’s early pictorial and written records make it clear that he was aware of and curious about the structural defects that from birth afflicted some of his fellow men. His attitudes about these congenital variants have ranged widely in different cultures: from romanticizing them in mythology, to using them as portent of coming events, to accepting them

Toward Nanomechanical Models of Liquid-Phase Exfoliation of Layered 2D Nanomaterials: Analysis of a π − peel Model

open access: yesFrontiers in Materials, 2019
In liquid-phase exfoliation for the production of 2D nanomaterials fluid forces are used to gently overcome adhesive interlayer forces, leading to single- or few-layer 2D nanomaterials.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

A new orthodontic force system for moment control utilizing the flexibility of common wires: Evaluation of the effect of contractile force and hook length

open access: yesJournal of the Formosan Medical Association, 2018
The application of an appropriate force system is indispensable for successful orthodontic treatments. Second-order moment control is especially important in many clinical situations, so we developed a new force system composed of a straight orthodontic ...

Theoretical Analysis of the Impact of Deviations in the Magneto-Rheological Damper Axis from the Runner Axis in the Butt of a Firearm During a Shot [PDF]

open access: yesProblemy Mechatroniki, 2017
This paper presents a method of modelling the impact of a magneto-rheological (MR) butt-mounted damper on both the weapon and the shooter during the use of a firearm. A modification of the model presented in [1] is suggested.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

THE MECHANICS AND MECHANISMS OF TOURISM BROKERING

open access: yesEthnologia Europaea, 2018
Although most forms of tourism are, and have always been, highly mediated activities, surprisingly little scholarly attention has been given to the crucial role of human brokers in tourism.

The mechanism of dishabituation [PDF]

open access: yesFrontiers in Integrative Neuroscience, 2014
The dual-process theory of habituation attributes dishabituation, an increase in responding to a habituated stimulus after an interpolated deviant, to sensitization, a change in arousal. Our previous investigations into elicitation and habituation of the electrodermal orienting reflex (OR) showed that dishabituation is independent of sensitization for ...
