Characterization of the sphericity of particles by the one plane critical stability

Journal of Pharmacy and Pharmacology, 1988
Abstract A method has been developed to characterize the roundness of particles in terms of the angle necessary to tilt a plane such that the particles would roll, the ‘one plane critical stability’. The method is based on determination of the centre of gravity of the particle from a digitized image of the coordinates of its outline and ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

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 ...

Crossover of critical behavior and magnetocaloric effect in FePd2Te2 with one-dimensional Fe chains [PDF]

APL Materials
Recently, a two-dimensional ferromagnet FePd2Te2 exhibiting easy-plane anisotropy with a quasi-one-dimensional spin system has been discovered. We report the magnetic critical behavior and magnetocaloric effect of FePd2Te2 single crystals with magnetic ...

Crossover and critical exponents for percolation in the semi-infinite plane

Journal of Physics A: Mathematical and General, 1986
The percolation problem in the semi-infinite plane is discussed in terms of the two competing length scales xi (p), the correlation length, and d, the distance from the surface. A crossover hypothesis for the percolation probability P(d, xi (p)) is proposed and two limiting regimes are identified.

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 ...

Diffraction by a half-plane in a moving fluid [PDF]

, 2005
In the following work we solve the problem of the diffraction of a plane sound wave by an impedance half-plane in a moving fluid. Expressions for the total far field are derived for both the leading edge and trailing edge situations. In the trailing edge

On building 4-critical plane and projective plane multiwheels from odd wheels

, 2012
We build unbounded classes of plane and projective plane multiwheels that are 4-critical that are received summing odd wheels as edge sums modulo two. These classes can be considered as ascending from single common graph that can be received as edge sum modulo two of the octahedron graph O and the minimal wheel W3. All graphs of these classes belong to

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

Influence of chirality on buckling of inextensible rings subject to dead loading

Vietnam Journal of Mechanics
A variational approach is studied to understand buckling of inextensible rings made from chiral filaments and subject to dead loading. In opposite to previous literatures in which only in-plane bifurcation is allowed, i.e., the ring deforms only in its ...
