Weak non-linearities of amorphous polymer under creep in the vicinity of the glass transition.

The creep behavior of an amorphous poly(etherimide) polymer is investigated in the vicinity of its glass transition in a weakly non linear regime where the acceleration of the creep response is driven by local configurational rearrangements. From the time shifts of the creep compliance curves under stresses from 1 to 15 MPa and in the temperature range between and , where is the glass transition temperature, we determine a macroscopic acceleration factor. The macroscopic acceleration is shown to vary as temperature with , where is the macroscopic stress and Y is a decreasing function of compliance.

Isolation-by-distance and isolation-by-oceanography in Maroon Anemonefish ().

Obtaining dispersal estimates for a species is key to understanding local adaptation and population dynamics and to implementing conservation actions. Genetic isolation-by-distance (IBD) patterns can be used for estimating dispersal, and these patterns are especially useful for marine species in which few other methods are available. In this study, we genotyped coral reef fish () at 16 microsatellite loci across eight sites across 210 km in the central Philippines to generate fine-scale estimates of dispersal.

Technology-Based Social Innovation: Smart City Inclusive System for Hearing Impairment and Visual Disability Citizens.

The multilayer technology integration of hardware and software will reduce the social inclusion gap and increase the support in case of an emergency for people with special needs at hearing and visual levels. This research shows a development based on Internet of Things to support people with visual disabilities (PwVD) for indoor and outdoor activities. The decision-making process is made at the operational, tactical, and strategic level, providing a safe place so people with visual and hearing special needs can make decisions, their families can make decisions, and the government authorities can make decisions in case of an emergency or even on a day-by-day basis.

Genomic signatures of spatially divergent selection at clownfish range margins.

Understanding how evolutionary forces interact to drive patterns of selection and distribute genetic variation across a species' range is of great interest in ecology and evolution, especially in an era of global change. While theory predicts how and when populations at range margins are likely to undergo local adaptation, empirical evidence testing these models remains sparse. Here, we address this knowledge gap by investigating the relationship between selection, gene flow and genetic drift in the yellowtail clownfish, from the core to the northern periphery of the species range.
