We investigate the effects of quantum fluctuations in a parity-time (PT) symmetric two-species Bose-Einstein condensate (BEC).It is found that the PT symmetry, though preserved by the macroscopic condensate, can be spontaneously broken by its Bogoliubov quasiparticles under quantum fluctuations.The associated PT-breaking transitions in the Bogoliub
Transposable elements (TEs) are mobile genomic sequences that are normally repressed to avoid proliferation and genome instability.Gene silencing mechanisms repress TEs by RNA degradation or heterochromatin formation.Heterochromatin maintenance is therefore important to keep TEs silent.Loss of heterochromatic domains has been linked to lamin mutati
Background: The prevalence of HIV is 0.1% in Pakistan, with epidemicity in high-risk groups.The infection is on verge of transmission from key populations to the general population through people who inject drugs and sexual transmission.Prisoners are vulnerable to infectious diseases like HIV.This study was conducted in four prisons in Balochistan,
In ship design, the matching of engine, propeller, and hull is an analytical process to establish the optimal operating mode so that the engine works safely with full power and the lowest fuel consumption, and a ship reaches desired speed.In theory, the operating process of the engine, hull, and propeller is usually expressed by their Pie Dish char
This paper investigates the performance assessment of liner shipping industry and presents a multi-dimensional evaluation framework to ensure both financial and non-financial monitoring.The traditional performance assessment approach is based on the financial indicators such as ratio analysis, but Pie Dish it is limited to the fiscal perspective.Th
