This paper deals with the automatic classification of customers on the basis of their movements around a sports shop center. We start by collecting coordinates from customers while they visit the store. Consequently, any costumer's path through the shop is formed by a list of coordinates, obtained with a frequency of one measurement per minute. A guess about the trajectory is constructed, and a number of parameters are calculated before performing a Clustering Process. As a result, we can identify several types of customers, and the dynamics of their behavior inside the shop. We can also monitor the state of the shop, identify different situations that appear during limited periods of time, and predict peaks in customer traffic.

The Sharp-van der Heijde score (SvH) is crucial for assessing joint damage in rheumatoid arthritis (RA) through radiographic images. However, manual scoring is time-consuming and subject to variability. This study proposes a multistage deep learning model to predict the Overall Sharp Score (OSS) from hand X-ray images.

Optical metabolic imaging captures the autofluorescent signal of two coenzymes, NADH and FAD, and offers a label-free approach to detect cellular metabolic phenotypes, track mitochondria morphology, and quantify metabolic heterogeneity. In this study, fluorescence lifetime imaging (FLIM) of NAD(P)H and FAD revealed that POLG mutator macrophages exhibit a decreased NAD(P)H lifetime, and optical redox ratio compared to the wild-type macrophages, indicating an increased dependence on glycolysis.

We report a case of GIN and de novo FSGS in kidney transplant recipients leading to allograft failure. A 69-year-old male with a history of end-stage renal disease (ESRD) of unknown etiology, as well as liver failure from hepatitis B and C co-infection, initially had a living unrelated kidney transplant (LURT) in 2007 and subsequently received both liver and kidney transplants (SLKTs) in 2017.

Purpose: Heterozygous mutations in the insulin gene can give rise to a monogenic diabetes syndrome due to toxic misfolding of the variant proinsulin in the endoplasmic reticulum (ER) of pancreatic β-cells. Clinical mutations are widely distributed in the sequence (86 amino acids). Misfolding induces chronic ER stress and interferes in with wildtype biosynthesis and secretion.

We aimed to build a robust classifier for the MGMT methylation status of glioblastoma in multiparametric MRI. We focused on multi-habitat deep image descriptors as our basic focus. A subset of the BRATS 2021 MGMT methylation dataset containing both MGMT class labels and segmentation masks was used.
