South Africa has the highest tuberculosis (TB) disease incidence rate in the world, and TB is the leading infectious cause of death.Decisions on, and funding for, TB prevention and care policies are decentralised to the provincial governments and therefore, tools to inform policy need to operate at this level.We describe the use of a mathematical m
A robust adaptive beamforming method is proposed in this paper for uniform linear arrays with respect to sensor gain and phase uncertainties.The sensor gain and phase parameters are obtained by solving a series of linear equations that describe the specific structure of the array covariance matrix for a uniform linear array.Partly calibrated parame
Background: This randomized split-mouth study aimed to evaluate the feasibility of ultrawide immediate implants in fresh extraction sockets of nonrestorable molars.The comparison was made with standard-diameter implants placed in healed ridges of missing molars.After 1 year of functional loading, both groups were assessed for crestal bone changes,
ABSTRACT Avian keratin disorder (AKD), characterized by debilitating overgrowth of the avian beak, was first documented in black-capped chickadees (Poecile atricapillus) in Alaska.Subsequently, similar deformities have appeared in numerous species across continents.Despite the widespread distribution of this emerging pathology, the cause of AKD rem
