We study micro price dynamics and their macroeconomic implications using daily scanner data from 1988 to 2013. We provide five facts. First, posted prices in Japan are ten times as flexible as those in the U.S. scanner data. Second, regular prices are almost as flexible as those in the U.S. and Euro area. Third, the heterogeneity of frequency and size of price change across products is sizable ...

Clinical neurology has been traditionally considered as an academic speciality in which the specialist regurgitates his/her knowledge of neurology without being able to do much for the patient. This attitude is no longer acceptable. Surge of information and discoveries in neurosciences within the last two decades translated into therapeutic interventions which is literally life saving in some o...

Searches for a permanent electric dipole moment (EDM) of fundamental particle started with the key idea by Ramsey and Purcell exploitation discrete symmetries, such as parity, more than seven decades ago. These searches provide model-independent test theoretical frameworks, in particular, Standard Model physics. Over time, large number experimentally suitable systems, also atoms molecules, prov...

Even though the constructs of climate and organisational culture were developed described for first time decades ago [...]

over seven decades ago, as the result of endeavors of a group of leading literary and scientific figures the farhangestan-e-awwal (first academy of iran) was established in may 1935 and its activity continued until 1953. presented here is a brief historical account of the establishment of the first academy of iran as well as a look at the biographical sketches of physicians at the academy.

The Relativistic Heavy Ion Collider (RHIC) has brought the study of spin effects in hadronic collisions to a new energy regime. In conjunction with other experiments at facilities around the world, much can be learned from the high-energy polarized proton collisions RHIC provides, allowing the collider to serve as a powerful tool to continue to understand the rich subtleties and surprises of sp...

The k-server problem is perhaps the most influential online problem: natural, crisp, with a surprising technical depth that manifests the richness of competitive analysis. The k-server conjecture, which was posed more that two decades ago when the problem was first studied within the competitive analysis framework, is still open and has been a major driving force for the development of the area...

During the recent decades, substantial changes are made in the borders and contents of physiology as a basic course for the students in medicine. Here some strategies are presented to preserve the classical and integrative approaches in teaching physiology, while these approaches extent our knowledge to molecular, sub-cellular and cellular levels.

background : the presence of hormones in milk and dairy foods was discussed decades ago but rather more concerns attended to that with respect to finding hormones as biomarkers in milk for diseases and pregnancy diagnosis. moreo-ver, considerable amount of studies demonstrated that existing of hormones in humans and animals milk are essential for infants growing and immunity. during the last co...
