As a typical case of the optimal planning for the provision of restricted medical resources, widespread vaccination is considered an effective and sustainable way to prevent and control large-scale novel coronavirus disease 2019 (COVID-19) outbreaks.However, an initial supply shortage of vaccines is inevitable because of the narrow production and l
The distribution pattern of periprostatic neurovascular bundles examined with successive celloidin slices
Abstract Background Although several distribution patterns of periprostatic neurovascular bundles have been proposed, variant Pentair E-Z Vac Parts dissection technique based on these patterns still confused surgeons.The aim of this study was to describe the periprostatic neurovascular bundles and their relationship with the fascicles around prosta
Quasi-Jacobi forms, elliptic genera and strings in four dimensions
Abstract We investigate the interplay between the enumerative geometry of Calabi-Yau fourfolds with fluxes and the modularity of elliptic genera in four-dimensional string theories.We argue Welding accessory that certain contributions to the elliptic genus are given by derivatives of modular or quasi-modular forms, which may encode BPS invariants o
