Extinct archosaurs, including many non-avian dinosaurs, exhibit relatively simply shaped condylar regions in their appendicular bones, suggesting potentially large amounts of unpreserved epiphyseal (articular) cartilage.This "lost anatomy" is often underappreciated such that the ends of bones are typically considered to be the joint surfaces, poten
Rock outcrops serve as unique habitats for several specialist species, yet their identification and conservation are challenged due to logistical and computational constraints.This study aimed to improve the accuracy and efficiency of locating sheer rock outcrops (>60 cm in height) using high- and medium-resolution digital elevation models (DEMs
Abstract Boundary conditions for a massless Dirac fermion in 2+1 dimensions where the space is a half-plane are discussed in detail.It is Neurovascular Health argued that linear boundary conditions that leave the Hamiltonian Hermitian generically break C P and T symmetries as well as Lorentz and conformal symmetry.We show that there is essentially
The Kingdom of Lesotho is beset by multiple challenges that hinder a full process of democratic consolidation.Like many other African countries, Lesotho is trapped in a myriad of challenges, including the politicization of independent institutions, such as the judiciary and security institutions, that contribute to perennial political instabilities
