Prepubertal gonadotropin-releasing hormone analog leads to exaggerated behavioral and emotional sex differences in sheep

In mammals, sex specialization is reflected by differences in brain anatomy and function. Measurable differences are documented in reproductive behavior, cognition, and emotion. We hypothesized that gonadotropin-releasing hormone (GnRH) plays a crucial role in controlling the extent of the brain's sex specificity and that changes in GnRH action during critical periods of brain development, such as puberty, will result in altered sex-specific behavioral and physiological patterns. We blocked puberty in half of the 48 same-sex Scottish mule Texel cross sheep twins with GnRH analog (GnRHa) goserelin acetate every 3 weeks, beginning just before puberty. To determine the effects of GnRHa treatment on sex-specific behavior and emotion regulation in different social contexts, we employed the food acquisition task (FAT) and measurement of heart rate variability (HRV). ANOVA revealed significant sex and sex × treatment interaction effects, suggesting that treated males were more likely to leave their companions to acquire food than untreated, while the opposite effect was observed in females. Concordant results were seen in HRV; treated males displayed higher HRV than untreated, while the reverse pattern was found in females, as shown by significant sex and sex × treatment interaction effects. We conclude that long-term prepubertal GnRHa treatment significantly affected sex-specific brain development, which impacted emotion and behavior regulation in sheep. These results suggest that GnRH is a modulator of cognitive function in the developing brain and that the sexes are differentially affected by GnRH modulation. [less ▲]

Prescribing metrics on the boundary of AdS 3-manifolds

in International Mathematics Research Notices (2016)

We prove that given two metrics g+ and g− with curvature κ<−1 on a closed, oriented surface S of genus τ≥2, there exists an AdS manifold N with smooth, space-like, strictly convex boundary such that the ... [more ▼]

We prove that given two metrics g+ and g− with curvature κ<−1 on a closed, oriented surface S of genus τ≥2, there exists an AdS manifold N with smooth, space-like, strictly convex boundary such that the induced metrics on the two connected components of ∂N are equal to g+ and g−. Using the duality between convex space-like surfaces in AdS3, we obtain an equivalent result about the prescription of the third fundamental form. [less ▲]

PRESEnCE: A Framework for Monitoring, Modelling and Evaluating the Performance of Cloud SaaS Web Services

Cloud Services Providers (CSPs) provide cloud services to the cloud customers in the pay-per-use model and use the Service Level Agreements (SLAs) to define the quality of the provided services. SLAs are just a contract which characterizing the performance and quality of the CSPs’ services. Unfortunately, There is not an automatic and standard mechanism to verify and assure that delivered services satisfy the signed SLA agreement. In this context, this work aimed at developing an automatic framework called PRESENCE, to evaluate the Quality of Service (QoS) for the deployment of the Software-as-a-Service (SaaS) Web Services (WSS) offered across several CSPs. This performance evaluation will be used to verify and check on the SLA contraventions. PRESENCE aims at quantifying in a fair and by stealth way the performance and scalability of the delivered WS. By stealthiness, we refer to the capacity of evaluating a given Cloud service through multiple workload patterns that makes them indistinguishable from a regular user traffic from the provider point of view. PRESENCE introduces a definition for the set of Common performance metrics for measuring the behavior of cloud applications on top of a given CSP. This framework opens a novel perspectives for SLA contraventions assessment, monitoring, modeling the performance metrics for SaaS WSs. [less ▲]
