Establishing different types of conservation zones is becoming commonplace. However, spatial prioritization methods that can accommodate multiple zones are poorly understood in theory and application. It is typically assumed that management regulations across zones have differential levels of effectiveness ("zone effectiveness") for biodiversity protection, but the influence of zone effectivene...

Being a secret, it’s best protected when it never leaves the safe zone. Proving identity involves communicating the secret to another party, which eventually exposes the whole or a part of the secret, in a direct or indirect (hashed) form. In the real world, authentication traffic passes thousands of systems between a prover (you) and a verifier (an entity which eventually decides whether your ...

This article explores the ways in which the court’s recognition of a broad zone of personal liberty in Lawrence v. Texas may serve to strengthen a woman’s constitutionally protected reproductive rights in future Supreme Court decisions. Part of the author’s analysis focuses on using particular Justices’ opinions (and dissents) to predict the direction of future challenges to abortion rights in ...

BACKGROUND: War-related trauma can present substantial reconstructive challenges. The use of local tissue for extremity reconstruction is often impossible secondary to the large zone of injury associated with blast injuries. However, the torso is general protected by modern body armor. The purpose of this study is to investigate our experiences and outcomes of two stage pedicle flap procedures ...

A severe outbreak of infection with type O, aphthovirus occurred in the Ramot Yissakhar nature reserve (Israel) in April 1985, resulting in the death of about half of a population of some 3,300 mountain gazelles (Gazella gazella). A smaller outbreak occurred in the southern Golan nature reserve among about 6,500 gazelles. Both outbreaks were controlled by shooting gazelles in a buffer zone arou...

The problem of herding a flock of birds is posed in a graph theoretic framework. A novel algorithm, called the n-wavefront algorithm, is developed for enabling a single unmanned aerial vehicle to herd a flock of birds to a desired point. The technique is applied to the problem of diverting a flock of birds approaching an airport away from a protected zone around the airport. The n-wavefront alg...

This new species (Phthiria sharafi sp. nov.) represents the first record of the subfamily Phthiriinae (Bombyliidae, Diptera) from Saudi Arabia. The species was collected from Garf Raydah Protected Area, Abha, Asir Province, south-western part of Saudi Arabia, using a Malaise trap erected in a site rich in olive, cactus and Juniper trees. The type locality has an Afrotropical influence, with the...

The exact power distribution of the inter-cell interference is obtained explicitly for cell edge users who are surrounded by circular guard zones. Compared with recent works, the underlying channel model is generalized from Rayleigh fading to a combination of Nakagami fading and Gamma shadowing. In addtion, asymptotic analysis shows that the mean power of intercell interference changes from inf...

In recent decades, necessity to protect environment has been a serious concern for all people and international communities. In appropriate development of human economic activities, subsistence dependence of the growing world population on nature decreases the natural diversity of ecosystems and habitats day by day and provides additional constraints for life and survival of wildlife. As a resu...
