Common Mechanisms for Calorie Restriction and AC5 Knockout Models of Longevity

Adenylyl cyclase type 5 knockout mice (AC5 KO) live longer and are stress resistant, similar to calorie restriction (CR). AC5 KO mice eat more, but actually weigh less and accumulate less fat compared to WT mice. CR applied to AC5 KO result in rapid decrea ...

Neutron diffraction investigations on residual stresses contributing to the fatigue crack growth in ferritic steel tubular bridges

Alain Nussbaumer, Claire Acevedo

Fatigue crack growth observed in tubular K-joint specimens, typical of tubular bridge structures, always initiates at the chord crown toe locations whether the applied stress range is tensile or compressive. Even though other locations around the weld have ...

Trait anxiety and post-learning stress do not affect perceptual learning

Michael Herzog, Maria del Carmen Sandi Perez, Aaron Michael Clarke, Carl Kristoffer Aberg

While it is well established that stress can modulate declarative learning, very few studies have investigated the influence of stress on non-declarative learning. Here, we studied the influence of post-learning stress, which effectively modulates declarat ...

Numerical study of the effect of confining stress on rock fragmentation by TBM cutters

Lijun Yin, Hongsu Ma

This paper investigates the effect of confining stress on rock fragmentation under TBM cutters by numerical simulation. Firstly, based on the characteristics of the force-penetration curve, the confining stress conditions for TBM tunneling are divided into ...

Studies of mode I delamination in monotonic and fatigue loading using FBG wavelength multiplexing and numerical analysis

John Botsis, Joël Cugnoni, Samuel Stutz

Bridging by intact fibers in composite materials is one of the most important toughening mechanisms. However, a direct experimental assessment of its contribution is not easy to achieve. In this work a semi-experimental method is proposed to quantify its c ...

Coupling quantum and continuum scales to predict crack tip dislocation nucleation

William Curtin, Derek Warner

A quantum-continuum multiscale coupling of Kohn-Sham density functional theory to continuum material is presented that can handle mechanics problems in metals when long-range stress fields are present, such as occurs for dislocations and cracks. The method ...

Testing continuum concepts for hydrogen embrittlement in metals using atomistics

William Curtin

Hydrogen embrittlement is a pervasive mode of degradation in many metallic systems that can occur via several mechanisms. Here, the competition between dislocation emission and cleavage at a crack tip is evaluated in the presence of H. At this level, embri ...

Geometry- and load-specific optimization of the collagen network's fibre orientation in the lumbar spine's annulus fibrosus

Andreas Schmocker

In Europe, low back pain (LBP) affects the quality of life of up to 30% of the active population. Although the origin of LBP is not well identified and is probably not unique, epidemiological studies suggest that the severity of the disease is correlated w ...

TENSILE CREEP OF UHPFRC UNDER LOW AND HIGH STRESSES

Eugen Brühwiler, Emmanuel Denarié, Agnieszka Ewa Switek

The purpose of this paper is to investigate experimentally the UHPFRC time-dependent behavior under sustained tensile loading and to determine the effect of the stress level on the creep response. Uniaxial tensile creep tests were performed at various stre ...

Smaller Global and Regional Cortical Volume in Combat-Related Posttraumatic Stress Disorder

Marie Schaer

Context Two sets of findings predict smaller cerebral cortical gray matter volume in adult posttraumatic stress disorder (PTSD). Measures of intracranial tissue volume and cerebral tissue volume have been observed to be smaller in adolescents with maltreat ...
