Birds are the most species-rich class of tetrapod vertebrates and have wide relevance across many research fields. We explored bird macroevolution using full genomes from 48 avian species representing all major extant clades. The avian genome is principally characterized by its constrained size, which predominantly arose because of lineage-specific erosion(More)
As top predators, falcons possess unique morphological, physiological and behavioral adaptations that allow them to be successful hunters: for example, the peregrine is renowned as the world's fastest animal. To examine the evolutionary basis of predatory adaptations, we sequenced the genomes of both the peregrine (Falco peregrinus) and saker falcon (Falco(More)
Design aspects and software modelling for ubiquitous real-time camera system are described in this paper. We propose system architecture using a network of inexpensive cameras and perform video processing in-network. In general , ubiquitous systems have to perform spatial and temporal calibration in advance to determine timing and coordination relationship(More)
BACKGROUND & AIMS Barrett's esophagus (BE) increases the risk of esophageal adenocarcinoma (EAC). We found the risk to be BE has been associated with single nucleotide polymorphisms (SNPs) on chromosome 6p21 (within the HLA region) and on 16q23, where the closest protein-coding gene is FOXF1. Subsequently, the Barrett's and Esophageal Adenocarcinoma(More)
Ross’s Gull is one of the most emblematic Arctic birds and least known seabirds in the world; post-breeding movements and the use of sea-ice habitats have been long debated, but described only from scattered observations. We tracked two adults, a male and female, breeding in the Kolyma Delta, Russia, using the lightest (<5 g) satellite transmitters(More)

INTRODUCTION Procedural sedation and analgesia have become standard practice in paediatric emergency departments worldwide. Although generally regarded as safe, serious adverse events such as bradycardia, asystole, pulmonary aspiration, permanent neurological injury and death have been reported, but their incidence is unknown due to the infrequency of their(More)
Artificial nests are a commonly used management technique to increase the breeding population and/or productivity of birds with nest site limited populations. We compared nest survival of saker falcons breeding in artificial nests erected in a flat steppe landscape with those breeding in natural nests on rocks and cliffs in adjacent hills of central(More)
Many different ecological factors affecting the size, use, and spatial configuration of home ranges have been investigated, yet the chronology of the breeding cycle has been relatively under studied. Here, we studied peregrine falcons (Falco peregrinus) to describe variation in home range within and between breeding seasons in the Yamal peninsula, a region(More)

INTRODUCTION Adverse events (AEs), defined as unintended patient harm related to healthcare provided rather than an underlying medical condition, represent a significant threat to patient safety and public health. The emergency department (ED) is a high-risk patient safety setting for many reasons including presentation 'outside of regular hours', high(More)
Thesis under the direction of Professor Janos Sztipanovits Versatile model-based design demands languages and tools which are suitable for the creation , manipulation, transformation, and composition of domain-specific modeling languages and domain models. The Meta Object Facility (MOF) forms the cornerstone of the OMG's Model Driven Architecture (MDA) as(More)
