Lorentzian condition in holographic cosmology

We derive a sufficient set of conditions on the Euclidean boundary theory in dS/CFT for it to predict classical, Lorentzian bulk evolution at large spatial volumes. Our derivation makes use of a canonical transformation to express the bulk wave function at large volume in terms of the sources of the dual partition function. This enables a sharper formulation of dS/CFT. The ...

Challenges in conducting natural experiments in parks—lessons from the REVAMP study

Experimental evidence on the role of the built environment for promoting physical activity is important for informing how to create cities that promote active living. Parks provide opportunities for physical activity; however, there is little robust evidence on the impact of park refurbishment. Government agencies often modify parks, providing opportunities for natural experiment ...

Effect of Traffic Signal Countdown Timers on Pedestrian Crossings at Signalized Intersection

Installations of signal countdown timers (SCTs) adjacent to the traffic signal heads are on the rise at several intersection locations in India. These SCTs provide information related to the time left for a particular signal phase and thus expected to help the driver take better decision. But no scientific studies were carried out before their installations at intersection ...

Human papillomavirus infection in anal intraepithelial lesions from HIV infected Cuban men

Background An association between HPV infection and progression to anal squamous intraepithelial lesions (ASIL) has been established, specifically in high-risk populations such as HIV-infected men. In this population, anal cancer is one of the most common non-AIDS-defining malignancies. Methods A cross-sectional study to detect anal lesions and HPV infection was performed. Anal ...

Characterization of LhSorP5CS, a gene catalyzing proline synthesis in Oriental hybrid lily Sorbonne: molecular modelling and expression analysis

Background Abiotic stresses negatively affect plant growth and flower production. In plants, P5CS proteins are key enzymes that catalyzed the rate-limiting steps of proline synthesis, and proline is a well-known osmoprotectant that is closely related to abiotic stress tolerance. However, information about the P5CS genes, their effects on proline accumulation, and their role in ...

Development and validation of SEER (Seeking, Engaging with and Evaluating Research): a measure of policymakers’ capacity to engage with and use research

Background Capacity building strategies are widely used to increase the use of research in policy development. However, a lack of well-validated measures for policy contexts has hampered efforts to identify priorities for capacity building and to evaluate the impact of strategies. We aimed to address this gap by developing SEER (Seeking, Engaging with and Evaluating Research), a ...

Groups of module automorphisms and Krull dimension and codimension

Let M be a module over the ring R and G a subgroup of \(\hbox {Aut}_{\mathrm{R}}\hbox {M}\). There has been interest of late in conditions on R, M and G such that one of [M, G] and \(\hbox {M}/\hbox {C}_{\mathrm{M}}(\hbox {G})\) small ensures that the other is also small. Here we consider when the Krull dimension (resp. codimension) of one of these bounds the Krull dimension (resp. ...

Human Biological and Psychological Diversity

Many evolutionary psychologists have asserted that there is a panhuman nature, a species typical psychological structure that is invariant across human populations. Although many social scientists dispute the basic assumptions of evolutionary psychology, they seem widely to agree with this hypothesis. Psychological differences among human populations (demes, ethnic groups, races) ...

Identification of positive selection in genes is greatly improved by using experimentally informed site-specific models

Background Sites of positive selection are identified by comparing observed evolutionary patterns to those expected under a null model for evolution in the absence of such selection. For protein-coding genes, the most common null model is that nonsynonymous and synonymous mutations fix at equal rates; this unrealistic model has limited power to detect many interesting forms of ...
