High-energy electron cooling, presently considered as an essential tool for several applications in high-energy and nuclear physics, requires an accurate description of the friction force which ions experience by passing through an electron beam. Present low-energy electron coolers can be used for a detailed study of the friction force. In addition, parameters of a low-energy cooler can be chos...

Two of recent progress in lattice QCD approach to nuclear force are reported. (i) Tensor force from quenched lattice QCD: By truncating the derivative expansion of inter-nucleon potential to the strictly local terms, we obtain central force VC r and tensor force VT r separately from swave and d-wave components of Bethe-Salpeter wave function for two nucleon state with JP 1 . Numerical calculati...

The photodiode sensitivity in the atomic force microscope is calibrated by relating the voltage noise to the thermal fluctuations of the cantilever angle. The method accounts for the ratio of the thermal fluctuations measured in the fundamental vibration mode to the total, and also for the tilt and extended tip of the cantilever. The method is noncontact and is suitable for soft or deformable s...

AIMS The myofibrillar and nuclear compartments in cardiomyocytes are known to be sensitive to extracellular mechanical stimuli. Recently, we have shown that alterations in the mitochondrial ionic balance in cells in situ are associated with considerably increased mitochondrial volume. Theoretically, this swelling of mitochondria could impose mechanical constraints on the myofibrils and nuclei i...

The main objective of this article is to explore the duality of strong interaction based on a new field equations of strong interaction. The field equations are derived by applying the principle of interaction dynamics (PID) and principle of representation invariance (PRI) to a standard QCD SU(3) gauge action functional. Intuitively, PID amounts to taking the variation of the action functional ...

The nucleus of a cell has long been considered to be subject to mechanical force. Despite the observation that mechanical forces affect nuclear geometry and movement, how forces are applied onto the nucleus is not well understood. The nuclear LINC (linker of nucleoskeleton and cytoskeleton) complex has been hypothesized to be the critical structure that mediates the transfer of mechanical force...

According to studies on the precursive time quantum variable, this publication presents an in-depth analysis of chapter correlation between nuclear mass and electroweak force. This research shows that there is a close energy orbitals which underlies interaction.

SUN (Sad1 and UNC-84) and KASH (Klarsicht, ANC-1, and Syne homology) proteins are constituents of the inner and outer nuclear membranes. They interact in the perinuclear space via C-terminal SUN-KASH domains to form the linker of nucleoskeleton and cytoskeleton (LINC) complex thereby bridging the nuclear envelope. LINC complexes mediate numerous biological processes by connecting chromatin with...

In this paper, the meson theory of nuclear forces is presented in a simplified way, As in Yukawa's first paper, the forces between two nuclear particles are derived directly from the field equations and the Hamiltonian of the meson field ($2,3), without quantization of the field. The charge dependence of the forces is discussed (f4) and it is found that only two assumptions are in agreement wit...
