Our paper addresses the problem of enforcing constraints in human body tracking. A projection technique is derived to impose kinematic constraints on independent multi-body motion: we show that for small motions the multi-body articulated motion space can be approximated by a linear manifold estimated directly from the previous body pose. We propose a learning approach to model non-linear const...

The dNab2 polyadenosine RNA binding protein is the D. melanogaster ortholog of the vertebrate ZC3H14 protein, which is lost in a form of inherited intellectual disability (ID). Human ZC3H14 can rescue D. melanogaster dNab2 mutant phenotypes when expressed in all neurons of the developing nervous system, suggesting that dNab2/ZC3H14 performs well-conserved roles in neurons. However, the cellular...

How does the sensory environment shape circuit organization in higher brain centers? Here we have addressed the dependence on activity of a defined circuit within the mushroom body of adult Drosophila. This is a brain region receiving olfactory information and involved in long-term associative memory formation. The main mushroom body input region, named the calyx, undergoes volumetric changes c...

Human pose estimation using deep neural networks aims to map input images with large variations into multiple body keypoints which must satisfy a set of geometric constraints and inter-dependency imposed by the human body model. This is a very challenging nonlinear manifold learning process in a very high dimensional feature space. We believe that the deep neural network, which is inherently an...

We describe a new species of the genus Ninia from the Chocó-Magdalena biogeographic province, which was previously reported as a distinct population of N. maculata or as N. atrata from the western slopes of the Cordillera Occidental of Colombia. The new species is similar to N. atrata, N. celata, N. espinali, N. franciscoi, and N. maculata. It shares the following characteristics with the speci...

The nose is the central part of the face, and constitutes the most prominent projection in facial geometry. This report presents five cases that sustained a chemical burn injury with associated facial mutilation resulting from contact with strong acids. The chemical burn affected the nasal architecture after inflicting a burn injury to the face. Applying bone deriving from a split skull procedu...

We perform a parametric study of the newly developed time-of-flight (TOF) image reconstruction algorithm, proposed for real-time imaging in total-body Jagiellonian PET (J-PET) scanners. The asymmetric 3D filtering kernel is applied at each most likely position electron-positron annihilation, estimated from emissions back-to-back γ-photons. optimisation its parameters studied using Monte Carlo s...
