Understanding the demographic response of free-living animal populations to different drivers is the first step towards reliable prediction of population trends. Penguins have exhibited dramatic declines in population size, and many studies have linked this to bottom-up processes altering the abundance of prey species. The effects of individual traits have(More)
Duchenne muscular Dystrophy (DMD) is an inherited disease caused by mutations in the dystrophin gene that disrupt the open reading frame, while in frame mutations result in Becker muscular dystrophy (BMD). Ullrich congenital muscular dystrophy (UCMD) is due to mutations affecting collagen VI genes. Specific muscle miRNAs (dystromirs) are potential(More)
Software Engineering (SE) design approaches are traditionally based on concepts associated with the procedural and object-oriented SE paradigms, such as stepwise methods and techniques for abstraction, modularity and refinement of software functionality. In contrast, researchers in other engineering domains have developed theories of Intelligent Design (ID)(More)
Cloud computing is maturing, becoming a viable alternative to classic on-premise IT. Cloud facilitates scalability, promising lower fixed and variable costs while supporting enterprise growth. The scalability benefits and cost savings can be achieved through on-demand infrastructure provisioning and reduced on-premise energy consumption. The benefits are(More)
OBJECTIVE Patients with Chronic Low Back Pain (CLBP) show arousal, attentional and cognitive disturbances. The sleep state-dependent P50 midlatency auditory evoked potential was used to determine if patients with CLBP [with and without co-morbid depression (DEP)] show quantitative disturbances in the manifestation of the P50 potential. METHODS P50(More)
A fully automated weighbridge using a new algorithm and mechanics integrated with a Radio Frequency Identification System is described. It is currently in use collecting data on Macaroni penguins (Eudyptes chrysolophus) at Bird Island, South Georgia. The technology allows researchers to collect very large, highly accurate datasets of both penguin weight and(More)
Information about prognosis can be applied to research design and is essential for patient care and counseling. Prognostic study data is only useful if it is valid, transparent, and applicable to your patient. Using a clinical scenario and a relevant study from the urological literature, we outline a method to appraise a prognostic article, understand the(More)
This methodological paper reports an initial attempt to evaluate the feasibility and utility of a nonverbal task for assessing generalized same/different judgments of auditory stimuli in individuals who have intellectual disabilities. Study 1 asked whether participants could readily acquire a baseline of auditory same/different, go-left/go-right performance(More)
