We introduce here the inaugural issue of the new scientific journal Translation. The overarching aim of this endeavor is to establish a new forum for a broad spectrum of research in the area of protein synthesis in living systems ranging from structural biochemical, evolutionary and regulatory aspects of translation to the fundamental questions related to post-translational control of somatic p...

cconcerning the emer gence of substantial changes in major cities within the past two decades and its relationship to a set of ideas which envisage the emergence of a new urban era, this article will try to examine the different aspects of the new urban policies as a necessary response to a new national and international economy. cconcerning the emer gence of substantial changes in major cities...

New wintering populations of Whooper Swan have been recently reported from west Asia, a lack of information about the population and its origin. The understanding the genetic structure and connectivity are crucial for determining strategies of management for its conservation programs. The samples were collected from two populations in northern Iran, Finland, Sweden, and Iceland, where with larg...

This paper analyzes the high-tech economies of 350-plus metropolitan areas across the U.S. during 2010. Attention is given to 20 different production attributes—including the age and education of the workforce, patent production, business startups, per capita productivity of the workers, and the like. Multivariate analysis is used to reduce these 20 attributes down to 10 orthogonal dimensions; ...

Results from an analysis of the intrinsic UV absorption in the Seyfert 1 galaxy NGC 3783 are presented. We focus on two new results that demonstrate techniques for deriving important constraints on the physical conditions and geometry of the absorbers. First, using variability in the spectrum, the emission-line profile is separated into distinct kinematic components and the effect on the interp...

Despite the availability of many drugs and therapies to treat malaria, many countries' national policies recommend using a single first-line therapy for most clinical malaria cases. To assess whether this is the best strategy for the population as a whole, we designed an evolutionary-epidemiological modeling framework for malaria and compared the benefits of different treatment strategies in th...

Context. This study follows a recent analysis of the galaxy luminosity functions and colour-magnitude red sequences in the Coma cluster (Adami et al. 2007). Aims. We analyze here the distribution of very faint galaxies and globular clusters in an east-west strip of ∼ 42 × 7 arcmin 2 crossing the Coma cluster center (hereafter the CS strip) down to the unprecedented faint absolute magnitude of M...

Detailed observation of the movement of individual animals offers the potential to understand spatial population processes as the ultimate consequence of individual behaviour, physiological constraints and fine-scale environmental influences. However, movement data from individuals are intrinsically stochastic and often subject to severe observation error. Linking such complex data to dynamical...

Gender equity is easily supported in theory but harder to pursue in practice. In this article, the case of Zika travel policies is used to illustrate some glaring gaps related to gender, for both men and women, at both international and national levels. Zika travel policies have not considered new evidence on biological or social determinants of health, putting babies at risk of exposure. The a...

This paper considers stochastic epidemics among a population partitioned into households, with mixing locally within households and globally throughout the population. The two levels of mixing have important implications for the threshold behaviour of the epidemic and consequently for the form and construction of optimal vaccination policies. Optimality is considered in terms of the cost of the...
