The external environment can have a profound impact on our brains and behavior. Yet, even with such a profound impact, it is often easy to ignore just how much the environment can affect us. This is exacerbated by the fact that humans have been able to manipulate their environment so effectively to ease daily life. Even so, the environment shapes our brains and behaviors tremendously. This arti...

Since its introduction just over two decades ago, evidence-based medicine (EBM) has come to dominate medical practice, teaching, and policy. There are a growing number of textbooks, journals, and websites dedicated to EBM research, teaching, and evidence dissemination. EBM was most recently defined as a method that integrates best research evidence with clinical expertise and patient values and...

The reduction of the six Bulgarian vowels (i, , a, , , u) to a fouror (in some dialects) three-vowel subsystem (i, ( ), , u) in unstressed syllables is generally accepted. But a number of studies disagree on the exact nature of the reduction process. Claims differ as to whether or not /a/ merges phonetically with / /, and / / with /u/, or whether the assumed neutralized oppositions take a phone...

In this paper, we discuss the nature of variability in compute performance in Infrastructure Clouds and how this presents opportunities for Cloud Service Brokers (CSB) in relation to pricing. Performance variation in virtual machines of the same type and price raises specific issues for end users : (i) the time taken to complete a task varies with performance, and therefore costs also vary (ii)...

A relational structure is called reversible iff every bijective endomorphism of that structure is an automorphism. We give several equivalents of that property in the class of disconnected binary structures and some its subclasses. For example, roughly speaking and denoting the set of integers by Z, a structure having reversible components is reversible iff its components can not be “merged” by...

The pattern of spontaneous chiral symmetry breaking (CSB) in confining background fields is analyzed. It is explicitly demonstrated how to get the inverse square root large proper time asymptotic of the operator product expansion which is needed for CSB.

The paper describes the efforts of three national libraries to use the DDC to improve access in German to the national bibliographies of Switzerland, Germany and Austria. The reasons that led to the use of the DDC for the organisation of the bibliographies and the difficulties in adopting a common approach will be explained. The paper will deal with the approach of using the Second Dewey Summar...
