Multi-human parsing aims to segment every body part of human instance. Nearly all state-of-the-art methods follow the “detection first” or “segmentation pipelines. Different from them, we present an end-to-end and box-free pipeline a new more human-intuitive perspective. In training time, directly do instance segmentation on humans parts. More specifically, introduce notion “indiscriminate obje...

introduction: the diagnosis of foreign bodies in the upper aerodigestive tract is usually straightforward but sometimes it can be delayed or the location of esophageal and upper airway foreign bodies can be mistakenly interchanged.  case report: we present two interesting cases that caused diagnostic challenges which could have led to serious complications if a greater delay in diagnosis had oc...

We perform, in a manifestly $SO(n-1,1)$ [$SO(n)$] covariant fashion, the Hamiltonian analysis of general relativity $n$ dimensions written as constrained $BF$ theory. solve constraint on $B$ field way naturally adapted to foliation spacetime that avoids explicitly introduction vielbein. This leads form action involving presymplectic structure, which is reduced by doing suitable parametrization ...

As an application of Hirota bilinear method, perturbation expansion truncated at different levels is used to obtain exact soliton solutions to (2+1)-dimensional nonlinear evolution equation in much simpler way in comparison to other existing methods. We have derived bilinear form of nonlinear evolution equation and using this bilinear form, bilinear Backlund transformations and construction of ...
