Beginning roughly two hundred years after the big-bang, a tresino phase transition generated Compton-scale composite particles and converted most of the ordinary plasma baryons into new forms of dark matter. Our model consists of ordinary electrons and protons that have been bound into mostly undetectable forms. This picture provides an explanation of the composition and history of ordinary to ...

Direct interaction with touchscreens has become a primary way of using a device. This work seeks to devise interaction methods for editing textual source code on touch-enabled devices. With the advent of the “Post-PC Era”, touch-centric interaction has received considerable attention in both research and development. However, various limitations have impeded widespread adoption of programming e...

This paper proposes the hypothesis that the low-frequency variability of the North Atlantic Oscillation (NAO) arises as a result of variations in the occurrence of upper-level Rossby wave–breaking events over the North Atlantic. These events lead to synoptic situations similar to midlatitude blocking that are referred to as high-latitude blocking episodes. A positive NAO is envisaged as being a...

We compare the pattern of intergenerational social mobility late in Soviet-era Russia with data collected recently. We find evidence of a strong vertical hierarchy in the Russian occupational structure both during and after the Soviet era. Gender-typing shaped men’s and women’s occupational opportunities in Russia, but origins affected men and women similarly. Social mobility decreased slightly...

OBJECTIVES Increasingly, hospitalists across the United States provide primary inpatient care for almost all subspecialty patients, including hematology and medical oncology. Febrile neutropenia (FN) is a serious condition often seen as a complication of cytotoxic chemotherapy or in patients with underlying bone marrow defects. The purpose of this study was to document the change of inpatient m...
