Dynamics of atom-atom entanglement in two-atom model with degenerate two-photon raman transitions
Вестник Самарского университета: Естественнонаучная серияThe exact dynamics of a model consisting of two two-level atoms interacting with the electromagnetic field mode of an ideal resonator through degenerate Raman transitions are found for coherent and thermal field states.

Skew information correlations beyond entanglement in dissipative two Su(2)-systems
Results in Physics, 2019 We investigate the dynamics of quantum correlations [including skew information correlations beyond entanglement] of two isolated Su(2)-systems that are initially in a maximum Bell state or in a separable state.

Berichte zur Wissenschaftsgeschichte, EarlyView.I present and discuss two drafts of remarks prepared by the mathematician Hermann Minkowski (1864–1909). They were composed in December 1907 while preparing his paper on the “Basic Equations of Electromagnetic Processes in Moving Bodies” for publication in the Proceedings of the Göttingen Academy of Sciences.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife
Biological Reviews, EarlyView.ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Business Strategy and the Environment, EarlyView.ABSTRACT Industrial clusters are central to the circular economy transition, yet how they develop into eco‐clusters and the paradoxical tensions this transformation fuels remain underexplored. Drawing on 48 in‐depth interviews and secondary data from a Turkish textile‐recycling cluster, we develop an empirically grounded model of eco‐cluster transition

Experimental observation of environment-induced sudden death of entanglement [PDF]
SPIE Proceedings, 2007 We demonstrate the difference between local, single-particle dynamics and global dynamics of entangled quantum systems coupled to independent environments. Using an all-optical experimental setup, we show that, while the environment-induced decay of each system is asymptotic, quantum entanglement may suddenly disappear.

Tonic–clonic seizures captured during ambulatory video‐EEG are frequently unreported
Epilepsia, EarlyView.Abstract Objective Tonic–clonic seizures (TCSs) are widely regarded as clinically obvious, yet seizure counts used for treatment decisions and risk counseling often rely on patient or caregiver diaries. We sought to quantify the frequency of unreported TCSs during prolonged ambulatory video‐EEG (vEEG) monitoring and examined associations with ...

Epilepsia, EarlyView.Abstract Objective Developmental and epileptic encephalopathies (DEEs) are characterized by drug‐resistant seizures and developmental slowing/regression. We examined the efficacy and tolerability of fenfluramine (FFA) in pediatric and adult patients with Lennox–Gastaut syndrome (LGS), Dravet syndrome (DS), and other DEEs.

Entanglement sudden death and sudden birth in two uncoupled spins [PDF]
Physica Scripta, 2009 We investigate the entanglement evolution of two qubits interacting with a common environment trough an Heisenberg XX mechanism. We reveal the possibility of realizing the phenomenon of entanglement sudden death as well as the entanglement sudden birth acting on the environment.
