The VideoWriter is an investigation into applying a natural user interface to telewriting. It employs a computer-controlled video camera to capture images of the user's writing space: a desk with various pieces of paper. The images are processed to extract the written marks on the current page from the clutter of objects in the scene, including the user's moving hand and pen. The system compres...

INTRODUCTION Early Clinical Exposure has been conceptualized to orient medical students towards actual clinical scenario and help them correlate their theoretical knowledge with real life situations in early years of MBBS courses. In the present study we explored the outcome of early clinical exposure in the context of basic science topics (Physiology) in fresh MBBS entrants and compared their ...

Renovators of old buildings sometimes discover concealed inscriptions made by past tradesmen. They are a means communicating with fellow workers and posterity passing on the traditional culture building trade. This article investigates collection graffiti created early nineteenth-century plumbers. It explores how why these marks were -in celebration tradesmen's skills - deduces their meanings, ...

The collision speed is important in accident analysis, and needle marks can be helpful as the physical evidence. The deceleration impact system has been built to analyze the mechanics of the needle and the gauge plate. Two isolated groups were designed to record the speed values under the same sample labels from real crashes. The visualization platform was built for the first group to collect n...

In this paper, we propose a secure anti-counterfeiting solution based on the extraction of a unique identifier out of the random profile of laser marks that are engraved on the surface or in the bulk of physical objects. Given today’s technology, the 3D profile of a laser mark can be considered uncloneable. Indeed, reproducing a mark would be so expensive that it thwarts any attempt to build a ...

In this issue of Blood,Gerber et al use aldehyde dehydrogenase (ALDH) activity to further subdivide the CD34(+)CD38(-) compartment in the bone marrow of acute myeloid leukemia (AML) patients. They identify a unique population with intermediate ALDH activity (ALDH(int)) that contains leukemia stem cells (LSCs). Moreover, persistence of this population after therapy is a marker of clinically sign...

During cytokinesis of a eukaryotic cell, following the chromosome movements of anaphase, a contractile ring forms in the cortex midway between the segregating chromosomes and divides the cell into two daughters. Recent studies have provided new insights into the mechanism by which the site of contractile ring assembly is specified.
