A 19-year-old man developed tremor in both hands and fatigue after starting work at a placer gold mine where he was exposed to mercury-gold amalgam. Examination revealed an intention tremor, dysdiadochokinesis and mild rigidity. The 24-h urinary mercury concentration reached a peak of 715 nmol/l (143 ug/l) shortly before the clinical examination, after which he was removed from working in the g...

Typomorphic features of placer gold conglomerates the Ortokinskaya formation Early Permian age (P1or) Sololiy Uplift Olenek High and modern channel alluvium Ortoku Eekit river, which drains these deposits, are studied. It is found that extremely heterogeneous composition complex inner structure typical vast majority conglomerates. There several stages different fineness (from 251‰ to 999‰) with...

Place labeling is the process of giving semantic labels to locations, such as home, work, and school. For a particular person, these labels can be computed automatically based on features of that person’s visits to these locations. A previous system called Placer used the person’s demographic data and the timing of their visits to label places with a learned decision tree. We developed Placer++...

In this paper we study the correlation between wirelength and routability for standard-cell placement problem, under the fixed-die place-androute environment. We present a placement tool with better routability for designs with high row utilization. Compared to a well-known industrial placement tool, our placer produces placements with equal or better routability, 13.2% better half-perimeter wi...
