Magnetic Interaction and X-Ray Absorption of the Magnetic Compact Stars [PDF]
Journal of Astronomy and Space Sciences, 1993 Using a simple analytic model based on the MHD stability arguments we obtain the size of the magnetosphere for the magnetic compact stars. We assume the ordered, fieldaligned flow in the magnetosphere and estimate the wellknown Alfven radius.

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

AN INJECTIVITY RADIUS ESTIMATE AND STABILITY OF MINIMAL SUBMANIFOLDS
Kyushu Journal of Mathematics, 1997 Various criteria under which a region \(\Delta \) in a minimal submanifold is stable have been found. Here, the authors choose to call a region \(\Delta \) stable if it is infinitesimally stable, i.e., the second variation operator for the volume functional is positive definite on the space of all variation fields on \(\Delta\).

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

A macroscopic traffic flow model considering driver memory effect on curves
Results in PhysicsIn real-world driving environments, curved roads are a common scenario that drivers must consider. Driver behavior is also a key factor in the study of traffic systems. This study investigates how factors such as curvature radius and friction coefficient
