... Three-dimensional (3D) brain organoids derived from human pluripotent stem cells (hPSCs), including human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs), have become a powerful system to study early development events and to model human disease . Cerebral organoids are generally produced in static culture or in a culture vessel with active mixing, and the two most widely used systems for mixing are a large spinning flask and a miniaturized multi-well spinning bioreactor (also known as Spin Omega (Spin)). The Spin provides a system that is amenable to drug testing, has increased throughput and reproducibility, and utilizes less culture media. However, technical limitations of this system include poor stability of select components and an elevated risk of contamination due to the overall setup of the device. Here, we report a new design of the miniaturized bioreactor system, which we term Spinꝏ, that overcomes these concerns to permit long-term experiments.

... Aim of this study was the description of finger movements in right-handed subjects during tactile exploration of a cuboid, a prototypical task of precise handling. The data consists of the time series of 29 sensors integrated in a glove for each hand of 22 subjects. Of the sensors, 16 recorded the bending of metacarpo-phalangeal (MCP) and proximal interphalangeal (PIP) joints of the fingers, MCP and (interphalangeal) IP joint of the thumb, palm arch and carpo-metacarpal (CMC) joint of the thumb, and abduction between fingers. Using principle component analysis we were able to segregate a short action into motor patterns related to successive manipulations of the object. The fraction of variance described by the principal components indicated that salient features of the single motor acts could be described for each hand by three components. Striking in the finger patterns are the prominent and varying roles of MCP and PIP joints of the fingers, and CMC joint of the thumb. An important aspect of the three components is their representation of distinct finger configurations within the same motor act. Analysis of the individual finger time series confirms synchrony during the task and graph analysis establishes high global efficiency of the network of interrelated finger joints. The computation of finger trajectories in one subject exemplifies the workspace of the task, which differs in the right and left hand. The study substantiates finger gaiting as principal mechanism underlying this prototypical task, ubiquitous in daily object shape recognition but described until now only in artificial systems.

... Previous research in gait recognition and available dataset focused on single subjects. But in real time environment (such as airport, metro stations etc.) more than one person walk in a group and occlusion factors affects the performance of gait recognition. Therefore, we presented a new dataset which focused dynamic occlusion scenario. We constructed two categories of gait dataset i.e. first, subjects walk in a group (SMVDU-Multi-Gait) and second, subjects walk separately (SMVDU-Single-Gait). The purpose of this dataset to analyze the variations in gait patterns when same subject walk in a group or individually and also to recognize the target subject in Multi-Gait.
