Deformation and Fracture of Thin Sheets of Nitinol [PDF]
, 2007 Nickel-Titanium (Nitinol) is a Shape Memory Alloy (SMA) that exhibits superelasticity (pseudoelasticity) and shape memory by a solid-solid state diffusion-less phase transformation.

A Computational Mechanism for Seeing Dynamic Deformation [PDF]
eneuro, 2019 Abstract Human observers perceptually discriminate the dynamic deformation of materials in the real world. However, the psychophysical and neural mechanisms responsible for the perception of dynamic deformation have not been fully elucidated. By using a deforming bar as the stimulus, we showed that the spatial frequency of deformation

On the deformation mechanism of re-entrant honeycomb auxetics under inclined static loads
, 2021 The present study focuses on the deformation mechanisms of re-entrant honeycomb auxetic structures under inclined loading. An auxetic finite element prototype is compressed by a rigid plate during a static Riks analysis.

Observing Deformation Mechanisms at Microscale
, 2022 For every project or application, it is important to select a material that exhibits the desired mechanical properties. To be able to do so, the performance of multiple materials needs to be determined via mechanical testing. Here, we present the ability to combine mechanical tests with microstructural observations, which gives new insight into the ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Deformation quantization of geometric quantum mechanics [PDF]
Journal of Physics A: Mathematical and General, 2002 Second quantization of a classical nonrelativistic one-particle system as a deformation quantization of the Schrodinger spinless field is considered. Under the assumption that the phase space of the Schrodinger field is $C^{\infty}$, both, the Weyl-Wigner-Moyal and Berezin deformation quantizations are discussed and compared. Then the geometric quantum

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Stress relaxation behavior of low carbon steel at different temperatures
Materials Research Express, 2023 In this paper, the stress relaxation behavior of Q235 with the initial tensile stress of 70, 85 and 100 MPa were investigated at different temperature. Based on the thermal activation theory, the stress relaxation model of Q235 steel was established, and

Deformed N = 8 Supersymmetric Mechanics [PDF]
Symmetry, 2019 We give a brief review of deformed N = 8 supersymmetric mechanics as a generalization of SU(2|1) mechanics. It is based on the worldline realizations of the supergroups SU(2|2) and SU(4|1) in the appropriate N = 8 , d = 1 superspaces. The corresponding models are deformations of the standard N = 8 mechanics models

FEBS 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 ...
