Global mineralogical mapping of Mars by the Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instrument on the European Space Agency's Mars Express spacecraft provides new information on Mars' geological and climatic history. Phyllosilicates formed by aqueous alteration very early in the planet's history (the "phyllocian" era) are found in the oldest terrains; sulfates ...
This year’s Early Research Achievements track attracted 40 submissions written by authors from 22 countries on 4 continents. After an intense reviewing process in which each paper was reviewed by at least 3 members of the ERA program committee, 15 papers were accepted by the 20 members of the ERA program committee. As expected, the majority of the papers covers traditional CSMR topics such as r...
The possible existence of a primordial magnetic field in the universe has been previously investigated in many articles. Studies involving the influence of a magnetic field in the nucleosyntesis era, studies considering the effects in the formation of structures during the radiation era and the matter era have been considered. We here assume the existence of a primordial magnetic field and stud...
We study the fine-tuning problem on the initial condition of inflation in the minimal supersymmetric standard model (MSSM), associated with the narrowness of the slow-roll region. We consider two cases before the onset of the MSSM inflation, namely, the radiation dominated era and preceding inflationary era. We find thermal dissipation does not induce additional friction to the inflaton, so tha...
serotypes and replacement by S aureus. However,while all staphylococcal pneumonia diagnoses significantly increased from the pre-PCV7 era to the early post-PCV7 era (P1⁄4.049), a nonsignificant decrease was observed in the late post-PCV7 era (P1⁄4.10), which includes the 2009-2010 influenza pandemic that was associated with an increase in secondary bacterial pneumonia. We also examined whether ...
Masculinization of the rodent brain is driven by estrogen signaling during a perinatal critical period. Genetic deletion of estrogen receptor alpha (Esr1/ERa) results in altered hypothalamicpituitary-gonadal (HPG) axis signaling and a dramatic reduction of male sexual and territorial behaviors. However, the requirement of ERa function in masculinizing distinct classes of neurons, and if these p...
Era, a Ras-like GTP-binding protein in Escherichia coli, has been shown to be essential for growth. However, its cellular functions still remain elusive. In this study, a genetic screening of an E. coli genomic library was performed to identify those genes which can restore the growth ability of a cold-sensitive mutant, Era(Cs) (E200K), at a restrictive temperature when expressed in a multicopy...
Over the past two decades, exponential growth of empirical research has fueled markedly increased concern about health disparities. In this paper, we show the progression of research on socioeconomic status (SES) and health through several eras. The first era reflected an implicit threshold model of the association of poverty and health. The second era produced evidence for a graded association...
This article proposes a conceptual framework to examine the development of the teacher education system in contemporary China. Within the framework, three development periods, including the era of shifan, and the era of post-shifan, the era of professional teacher education, are investigated in terms of governance, institutional structures, and resource allocation. With the central government d...
