We report X-ray observations of the nearby, powerful radio galaxy Pictor A with the Chandra Observatory and optical and near uv observations of its western radio hot spot with the Hubble Space Telescope. X-ray emission is detected from the nucleus, a 1. ′ 9 (110 kpc) long jet to the west of the nucleus, the western radio hot spot some 4. ′ 2 (240 kpc) from the nucleus, and the eastern radio lob...

Dramatic population declines have affected frogs worldwide (1), and, although new species continue to be described (2), the discovery of large new species radiations is rare. Here, we report the discovery of an endemic radiation of 100 species of Old World tree frogs (Rhacophorinae) from Sri Lanka, an island from which only 18 rhacophorine species were known previously (3). An extensive survey,...

Forest fires are an important problem for many countries. Prevention, surveillance and extinguishing tasks are costly and sometimes risky. This paper focuses on the surveillance of the fire embers once the fire is extinguished. This is a post-fire task which requires an important amount of terrestrial resources, especially if the weather conditions may provoke the re-ignition of the fire. We pr...

Many central metabolic processes require iron (Fe) as a cofactor and take place in specific subcellular compartments such as the mitochondrion or the chloroplast. Proper Fe allocation in the different organelles is thus critical to maintain cell function and integrity. To study the dynamics of Fe distribution in plant cells, we have sought to identify the different intracellular iron pools by c...

Abstract – In this paper we present an algorithm for fast geolocation of hot spots from an infrared image taken from an unmanned aircraft. The input data are the position and attitude of the aerial platform, and the digital elevation model of the t...

Heterozygous missense mutations in the N-terminal motor or coiled-coil domains of the kinesin family member 5A (KIF5A) gene cause monogenic spastic paraplegia (HSP10) and Charcot-Marie-Tooth disease type 2 (CMT2). Moreover, heterozygous de novo frame-shift mutations in the C-terminal domain of KIF5A are associated with neonatal intractable myoclonus, a neurodevelopmental syndrome. These finding...

Spectra for the emission of charged leptons from evaporating hot-spots of preconfining phase in SU(2) Yang-Mills thermodynamics are computed. Specifically, we consider charged single and dileptons with their spectra being functions of energy and invariant mass, respectively. In the former case, our results relate to narrow and correlated electron and positron peaks measured in supercritical hea...

1. Introduction Together with the chemical effects of ultrasound, light is often emitted [1-5]. Such sonoluminescence provides an extremely useful spectroscopic probe of the conditions created during cavitation bubble collapse. Acoustic cavitation is the origin of both sonochemistry and sonoluminescence. The collapse of bubbles caused by cavitation produces intense local heating and high pressu...

With the increasing levels of variability in the behavior of manufactured nano-scale devices and dramatic changes in the power density on a chip, timely identification of hot spots on a chip has become a challenging task. This paper addresses the questions of how and when to identify and issue a hot spot alert. There are important questions since temperature reports by thermal sensors may be er...
