When I woke up on the morning of Tuesday 27th June 2000, I noticed no change at all. I telephoned a few friends and they confirmed that their lives were not much different that morning. One said he had a slight hangover but he could account for this minor deviation. For years we had been told that once we had the sequence of the human genome, everything would change. So how come after the rough...

We introduce the notion of empty alternation by investigating alternating automata which are restricted to empty their storage except for a logarithmically space-bounded tape before making an alternating transition. In particular, we consider the cases when the depth of alternation is bounded by a constant or a polylogarithmic function. In this way we get new characterizations of the classes AC...

Recent work (Hu and Black (2005, 2007, 2008); Dekel and Wolinsky (2012)) has detailed the twin issues of empty voting and hidden/morphable ownership. The former arises when an actor has control rights over a corporation but no economic interest in that corporation, such as when an investor borrows shares. The latter arises when a shareholder has an economic or voting interest in a corporation b...

Between 1880 and 2000, the percentage of married men 60 and older living only with their wives in empty nest households rose from 19 percent to 78 percent. Data drawn from the US census show that more than half of this transformation occurred in the 30-year period from 1940 to 1970, bookended by moderate increases between 1880 and 1940 and very modest increases after 1970. Two literatures have ...

The COVID-19 epidemic has had a great impact on people’s work and life since 2019. In the football industry, of pandemic never been so obvious. First, there was massive league lockout, then postponement European Championship held every four years. Despite efforts made by everyone from federation to country get back track, loss empty matches remains indelible. From economic level athletic level,...

Previous studies showed that heart period decreases during and recovers after an acute stress. We investigated if individual predispositions and emotional priming influence heart period recovery after a speech stress task. Psychometric scales and resting cardiac vagal tone were used to measure individual traits. The presentation of a sequence of either pleasant or unpleasant pictures, as emotio...

Objective(s) The objective of this study was to prepare, characterize and evaluate the nanoliposomes containing safranal as a natural sunscreen and moisturizer factor. Materials and Methods The experimental formulations included homosalate reference, nanoliposomes containing 0.25, 0.5, 1, 2, 4 and 8% safranal and empty liposomes. The liposomes were prepared using fusion method and homogeniza...

The purpose of this study was to characterize the recovery pattern of sleep following simulated, four successive night shifts in ten healthy men (22.9 + or - 3.2 yr). Poor sleep was defined as sleep efficiency of 80% or lower as determined actigraphically. The results showed that four (rapid, slow, pseudo, and incomplete) patterns of sleep recovery were observed over three recovery sleep period...

In adult animals, the consequences of stress are often severe and long lasting. Repeated subjugation in adult male golden hamsters inhibits aggression and increases submissive and avoidant behaviours. By contrast, subjugation during puberty enhances offensive aggression. The goals of this study were to characterize behavioural and neuroendocrine responses of naïve and repeatedly subjugated juve...
