A Theoretical Model for a Fermi–Boson Hybrid Particle in Nuclear and Particle Physics
Abstract: We present a theoretical model for a Fermi–Boson Hybrid Particle (FBHP) that unifies fermionic half-integer spin matter fields with bosonic integer-spin force fields within a single quantum framework. By extending conventional quantum field theory, a hybrid creation operator is formulated that combines fermionic and bosonic operators through a continuous mixing parameter, allowing smooth interpolation between Fermi–Dirac and Bose–Einstein statistical behaviour. A generalized statistical mechanics formalism is developed, leading to quantitative …

Review on Persistent Threat of Monkeypox
Abstract: Monkeypox virus (at this instant notorious as MPXV, the virus that sources the lately rechristened infection monkeypox) was learned at Denmark’s State Serum Organization in 1958, which is closely like smallpox. For the next 50 years, monkeypox was primarily confined to tiny, sporadic epidemics in western and central Africa. These epidemics were primarily caused by spillover episodes, in which the virus sprang through a host animal to a human, followed …
