It seems that we are again in the midst of a new storm of concern about an epidemic of benzodiazepine (BZ) overuse, misuse, and abuse. The first concern, in the 1980s, posited BZs as an epidemic of excessive prescribing and was frequently mentioned in books, movies, and numerous lay magazine articles. There was also concern that BZs were abused or misused, caused addiction with difficult withdr...

We present the proof of the equivalence theorem in quantum field theory which is based on a formulation of this problem in the field-anitfield formalism. As an example, we consider a model in which a different choices of natural finite counterterms is possible, leading to physically non-equivalent quantum theories while the equivalent theorem remains valid.

A recent study shows that prolonged inhibition of bacterial cell division causes a block of DNA replication, which is followed by an irreversible cell cycle arrest. The finding indicates a tight coupling between cell division and DNA replication in bacteria.

The vast majority of published work in the field of associative learning seeks to test the adequacy of various theoretical accounts of the learning process using average data. Of course, averaging hides important information, but individual departures from the average are usually designated "error" and largely ignored. However, from the perspective of an individual differences approach, this er...
