Tides from the cloud can induce the fast disruption of star clusters and offer an explanation for Gaia strings
Young stars form in clusters within molecular clouds, but older stars are evenly distributed across the galactic disk, necessitating an explanation for cluster dissolution. We analytically study tidal forces from cold molecular clouds as a key mechanism for accelerated cluster disruption. Cloud tides, caused by the gravitational pull of the parent cloud along the radial direction, arise from the spatial gradient of gravitational acceleration and drive cluster disruption. This mechanism activate…

Unlocking the initial neutron density distribution from the two-pion HBT correlation function in heavy-ion collisions
Revealing the neutron density distribution in the nucleus is one of the crucial tasks of nuclear physics. Within the framework of the ultrarelativistic quantum molecular dynamic model followed by a correlation afterburner program, we investigate the effects of the initial neutron density distribution on the charged-pion yield ratio $π^{-}/π^{+}$, the two-pion momentum correlation function, and the emission source dimension. It is found that the $π^{-}/π^{+}$ ratio is sensitive to the initia…

Dzisiejsza demonstracja pod Ministerstwem Aktywów Państwowych ws. embarga na dostawy materiałów wybuchowych do USA.
18 listopada br. organizacja Palestinian Youth Movement opublikowała opracowanie, które opisało rolę naszego kraju - a konkretniej firmy Nitro-Chem z Bydgoszczy - w dostawach trotylu do produkcji broni wykorzystywanej przez Izrael w Gazie. Od ponad dekady firma ta jest czołowym producentem i eksporterem TNT w NATO i UE i odpowiada za 90% eksportu tego materiału do USA. A ten kraj z kolei wykorzystuje go do produkcji bomb i amunicji dostarczanej izraelskiej armii i wykorzystywanej w Gazie.
Cytując opracowanie: “Bez trotylu (TNT) wyprodukowanego w Polsce niemożliwa byłaby bezprecedensowa skala i intensywność bombardowań z powietrza, które pochłonęły życie dziesiątek tysięcy Palestyńczyków i zniszczyły warunki życia w Strefie Gazy”.

A Coalgebraic Model of Quantum Bisimulation
Recent works have shown that defining a behavioural equivalence that matches the observational properties of a quantum-capable, concurrent, non-deterministic system is a surprisingly difficult task. We explore coalgebras over distributions taking weights from a generic effect algebra, which subsumes probabilities and quantum effects, a physical formalism that represents the probabilistic behaviour of an open quantum system. To abide by the properties of quantum theory, we introduce monads grade…

CGSim: A Simulation Framework for Large Scale Distributed Computing Environment
Large-scale distributed computing infrastructures such as the Worldwide LHC Computing Grid (WLCG) require comprehensive simulation tools for evaluating performance, testing new algorithms, and optimizing resource allocation strategies. However, existing simulators suffer from limited scalability, hardwired algorithms, lack of real-time monitoring, and inability to generate datasets suitable for modern machine learning approaches. We present CGSim, a simulation framework for large-scale distribu…

Voltage-sensitive distribution factors for contingency analysis and topology optimization
Topology optimization is a promising approach for mitigating congestion and managing changing grid conditions, but it is computationally challenging and requires approximations. Conventional distribution factors like PTDFs and LODFs, based on DC power flow, fail to capture voltage variations, reactive power, and losses - limiting their use in detailed optimization tasks such as busbar splitting. This paper introduces generalized distribution factors derived from a voltage-sensitive linearizatio…

Fire severity and recovery across Europe: insights from forest diversity and landscape metrics
In recent decades, European forests have faced an increased incidence of fire disturbances. This phenomenon is likely to persist, given the rising frequency of extreme events expected in the future. Estimating canopy recovery time after disturbance serves as a critical assessment for understanding forest resilience, which can ultimately help determine the ability of forests to regain their capacity to provide essential ecosystem services. This study estimated fire severity and post-disturbance …
