BV Stellar Photometry of 23 Galactic Globular Clusters [PDF]
Journal of Astronomy and Space Sciences, 1998 We report V-(B - V) CCD Color Magnitude Diagrams (CMDs) for 23 southern Galactic globular clusters. Limiting magnitudes for each cluster are between 18 and 20 magnitudes in V.

Advanced Science, EarlyView.Cryo‐EM reveals a closed 17‐subunit LH ring encircling the RC‐LH1 complex in Dinoroseobacter shibae, featuring a novel helix‐turn‐helix subunit bridging RC and LH. Mg2⁺/Ca2⁺ stabilizes the complex, while periplasmic Cyt c₂ mediates electron transfer via a tri‐heme Cyt to the special pair of bacteriochlorophylls. Insights into energy/electron efficiency

On the critical branching random walk II: Branching capacity and branching recurrence [PDF]
arXiv, 2016 We continue our study of critical branching random walk and branching capacity. In this paper we introduce branching recurrence and branching transience and prove an analogous version of Wiener's Test.

Rotation of Horizontal Branch Stars in Globular Clusters [PDF]
, 1999 The rotation of horizontal branch stars places important constraints on angular momentum evolution in evolved stars and therefore rotational mixing on the giant branch. Prompted by new observations of rotation rates of horizontal branch stars, we calculate simple models for the angular momentum evolution of a globular cluster giant star from the base ...

A Branch Group in a Class of Non-Contracting Weakly Regular Branch Groups [PDF]
arXiv, 2023 We provide a class of non-contracting groups containing an infinite family of fractal and weakly regular branch groups, and study certain properties including abelianization, just infiniteness, and word problem. We present an example of a branch group in this class and show that it is of exponential growth.

Lattice‐Distortion‐Driven Reduced Lattice Thermal Conductivity in High‐Entropy Ceramics
Advanced Science, EarlyView.Long‐believed potential mechanisms of lattice distortion and mass fluctuation for the reduced lattice thermal conductivity are explored by designing two groups of high‐entropy diborides based on machine‐learning‐potential‐based molecular dynamics simulations.

On the critical branching random walk I: Branching capacity and visiting probability [PDF]
arXiv, 2016 We extend the theory of discrete capacity to critical branching random walk. We introduce branching capacity for any finite subset of $\Z^d, d\geq5$. Analogous to the regular discrete capacity, branching capacity is closely related to the asymptotics of the probability of visiting a fixed finite set by a critical branching random walk starting from a ...

Edge of Chaos Theory Unveils the First and Simplest Ever Reported Hodgkin–Huxley Neuristor
Advanced Electronic Materials, EarlyView.This manuscript presents the first and simplest ever‐reported electrical cell, which leverages one memristor on Edge of Chaos to reproduce the three‐bifurcation cascade, marking the entire life cycle from birth to extinction via All‐to‐None effect of an electrical spike, also referred to as Action Potential, across axon membranes under monotonic ...

Designed Biomaterial‐Enhanced Cell Transplantation for Neural Tissue Engineering
Aggregate, EarlyView.Biomaterials offer a promising solution for cell transplantation in the central nervous system by creating a protective environment that enhances cell survival, integration, and functional recovery in preclinical models of neurological disorders. ABSTRACT Cell transplantation therapy in the central nervous system is hindered by limited survival and ...
