In 1940, the Hungarian mathematician Paul Turán was sent to a forced labor camp by the Nazis. Though every part of his life was brutally controlled, he still managed to do serious mathematics under the most extreme conditions. While forced to collect wire from former neighborhoods, he would be thinking about mathematics. When he found scraps of paper, he wrote down his theorems and conjectures....

The certificate is a valuable document, and it is of great importance that every doctor should so regard it.The total amount paid away every year in sickness and disablement benefits is over ?11,000,000. It stands to reason that, as the incapacity from work which entitles the insured person to receive the cash payment must be incapacity resulting from " some specific disease or bodily or mental...

Free [Ca ] inside the sarcoplasmic reticulum ([Ca ]SR) is difficult to measure yet critically important in controlling many cellular systems. In cardiac myocytes, [Ca ]SR regulates cardiac contractility. We directly measure [Ca ]SR in intact cardiac myocytes dynamically and quantitatively during beats, with high spatial resolution. Diastolic [Ca ]SR (1 to 1.5 mmol/L) is only partially depleted ...

This paper concentrates on a study of a novel multi-sensor aided method by using acoustic and visual sensors for detection, recognition and separation of End-of Life vehicles' (ELVs) plastic materials, in order to optimize the recycling rate of automotive shredder residues (ASRs). Sensor-based sorting technologies have been utilized for material recycling for the last two decades. One of the pr...
