Probability of disease extinction and outbreak in a stochastic tuberculosis model with fast-slow progression and relapse

A stochastic continuous-time Markov chain tuberculosis model with fast-slow progression and relapse is established to explore the impact of the rainier fabrics demographic variation on TB transmission.At first, the extinction threshold and probability of the disease extinction and outbreak are obtained by applying the multitype Galton-Waston branch

Strong-Scattering Multiparameter Reconstruction Based on Elastic Direct Envelope Inversion and Full-Waveform Inversion with Anisotropic Total Variation Constraint

Strong-scattering medium can usually form a good sealing medium for oil and mg09aca18te gas resources.However, conventional elastic full-waveform inversion (EFWI) methods are difficult to build reliable velocity models under the condition of lacking low-frequency information.The elastic direct envelope inversion (EDEI) method has been proven to be

Are dogs with congenital hearing and/or vision impairments so different from sensory normal dogs? A survey of demographics, morphology, health, behaviour, communication, and activities.

The births of domestic dogs with pigment deletion and associated congenital hearing and/or vision impairments are increasing, as a result of mutations of certain genes expressing popular coat colour patterns (Merle, piebald, Irish spotting).The future of these dogs is often pessimistic (early euthanasia or placement in rescues/fosters, lack of inte
