Quantum chaos of a mixed, open system of kicked cold atoms

open access: yes, 2010
The quantum and classical dynamics of particles kicked by a gaussian attractive potential are studied. Classically, it is an open mixed system (the motion in some parts of the phase space is chaotic, and in some parts it is regular).

Optimal Network Reconfiguration to Improve Network Reliability and Voltage Profile in Distribution Systems Using Chaotic Linear Decreasing Inertia Weight‐Based Particle Swarm Optimization

open access: yesEngineering Reports, Volume 8, Issue 2, February 2026.
Graphical abstract illustrates the optimization process in MATLAB software for network reconfiguration to improve reliability and voltage profile using PSO‐CLDIW. ABSTRACT The growing energy demand has intensified reliability challenges in power distribution systems.

Local Writhing Dynamics

open access: yes, 1997
We present an alternative local definition of the writhe of a self-avoiding closed loop which differs from the traditional non-local definition by an integer. When studying dynamics this difference is immaterial.

“Crucifixion” of the Logic. Palamite Theology of the Uncreaded Divine Energies as Fundament of an Ontological Epistemology [PDF]

open access: yesInternational Journal of Orthodox Theology, 2015
During the Transfiguration, the apostles on Tabor, “indeed saw the same grace of the Spirit which would later dwell in them”. The light of grace “illuminates from outside (ἔξωθεν) on those who worthily approached it and sent the illumination to the soul ...

The regional evolution of a dryland fluvio‐aeolian and lacustrine succession in response to allocyclic forcing: insights from the Early Permian Cutler Group, Utah, USA

open access: yesSedimentology, Volume 73, Issue 2, Page 297-354, February 2026.
ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.

Cooling flows and quasars: different aspects of the same phenomenon? I. Concepts [PDF]

open access: yes, 1997
We present a new class of solutions for the gas flows in elliptical galaxies containing massive central black holes (BH). Modified King model galaxies are assumed. Two source terms operate: mass loss from evolving stars, and a secularly declining heating

Environmental DNA Reflects Differences in Freshwater Habitat Use Between Two Pacific Salmonids at Fine Temporal Scales

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
A year‐long eDNA survey was conducted in two Canadian rivers to track changes in Chinook and coho salmon freshwater habitat occupancy. eDNA concentrations were aligned with known migratory and spawning patterns, with Chinook signals peaking earlier than coho. These findings highlight eDNA as a temporally sensitive tool for monitoring salmon life stages

Black-Hole X-Ray Transients: The Effect of Irradiation on Time-Dependent Accretion Disk Structure

open access: yes, 1999
Some effects of irradiation on time-dependent accretion-disk models for black hole X-ray novae are presented. Two types of irradiation are considered: direct irradiation from the inner hot disk and indirect irradiation as might be reflected by a corona ...

Gregory Palamas’ Polemic against Nicephorus Gregoras: The Aspects of Syllogisms and of the Authors’ Attitudes Towards Secular Philosophy

open access: yesАнтичная древность и средние века
Gregory Palamas’ treatise Against the False Writings by Gregoras is not only a theological and polemical treatise on the nature of the Taboric light, as well as on the essence-energy relation in God, but also a pamphlet (psogos), shaping a negative image
