Rotational surfaces of constant astigmatism in space forms [PDF]

Journal of Mathematical Analysis and Applications, 2020
A surface in a Riemannian space is called surface of constant astigmatism if the difference between the principal radii of curvature at each point is a constant function.

Surface Chirality in Rotational Magnetoelectrodeposition of Copper Films

Magnetochemistry, 2019
Chiral surface formation was investigated in rotational magnetoelectrodeposition (RMED) of copper films, where an electrochemical cell was rotated in magnetic fields.

On the duality between rotational minimal surfaces and maximal surfaces

Journal of Mathematical Analysis and Applications, 2018
We investigate the duality between minimal surfaces in Euclidean space and maximal surfaces in Lorentz-Minkowski space in the family of rotational surfaces. We study if the dual surfaces of two congruent rotational minimal (or maximal) surfaces are congruent. We show that in the duality process by means of a one-parameter group of rotations, it appears

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

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 ...

The effect of rotational velocity on rotational traction across a range of artificial turf surface systems

Scientific Reports, 2023
Mechanical testing by sporting governing bodies ensures artificial turf surfaces conform with performance standards. Rotational traction is measured using two equivalent devices: a rotational traction tester (RTT) and a lightweight rotational traction ...

Biophysical approaches for studying viral entry

FEBS 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

Model and formulation in grinding mechanism having advanced secondary rotational axis

Measurement + Control, 2019
“Grinding Mechanism having Advanced Secondary Rotational Axis” is one of the newer plane surface grinding methods that has an uncommon abrasion mechanism. Unlike conventional methods, in Grinding Mechanism having Advanced Secondary Rotational Axis, there

Electrical discharge turning by assistance of external magnetic field, part II: Study of surface integrity

International Journal of Lightweight Materials and Manufacture, 2020
Surface integrity as one of the main outcomes of hybrid machining process has dominant effect on the life time of engineering material. In this work, surface integrity of the AISI D2 steel grooves produced by electrical discharge turning (EDT) process ...

Flare differentially rotates sunspot on Sun’s surface [PDF]

Nature Communications, 2016
AbstractSunspots are concentrations of magnetic field visible on the solar surface (photosphere). It was considered implausible that solar flares, as resulted from magnetic reconnection in the tenuous corona, would cause a direct perturbation of the dense photosphere involving bulk motion.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
