Very high energy gamma-rays probe the long-standing mystery of the origin of cosmic rays. Produced in the interactions of accelerated particles in astrophysical objects, they can be used to image cosmic particle accelerators. A first-sensitive survey of the inner part of the Milky Way with the High Energy Stereoscopic System (HESS) reveals a population of eight previously unknown firmly detected sources of very high energy gamma-rays. At least two have no known radio or x-ray counterpart and may be representative of a new class of "dark" nucleonic cosmic ray sources.

A Particle Consistent with the Higgs Boson Observed with the ATLAS Detector at the Large Hadron Collider Aad, G.; et. al. (American Association for the Advancement of Science (AAAS), 2012-12-21) Nearly 50 years ago, theoretical physicists proposed that a field permeates the universe and gives energy to the vacuum. This field was required to explain why some, but not all, fundamental particles have mass. Numerous precision measurements during recent decades have provided indirect support for the existence of this field, but one crucial prediction of this theory has remained unconfirmed despite 30 years of experimental searches: the existence of a massive particle, the standard model Higgs boson. The...
A New Boson with a Mass of 125 GeV Observed with the CMS Experiment at the Large Hadron Collider Chatrchyan, S.; et. al. (American Association for the Advancement of Science (AAAS), 2012-12-01) The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would verify the existence of a complex scalar field thought to give mass to three of the carriers of the electroweak force-the W+, W-, and Z(0) bosons-as well as to the fundamental quarks and leptons. The CMS Collaboration has observed, with a statistical significance of five standard deviations, a...
Atmospheric iridium at the South Pole as a measure of the meteoritic component Tuncel, Süleyman Gürdal (Springer Science and Business Media LLC, 1987-10) The measurement of iridium (Ir) in atmospheric samples is important because it gives information on the short-term flux of extraterrestrial material without interference from fragmentation products from large bodies. Such information cannot be obtained from sediment samples, because sediment samples integrate over millions of years and include contributions of large bodies impacted in that time period. In addition to flux information, through the analysis of Ir in atmospheric samples we can also evaluate a ...
Blue-phase liquid crystal droplets Martinez-Gonzalez, Jose A.; Zhou, Ye; Rahimi, Mohammad; Büküşoğlu, Emre; Abbott, Nicholas L; de Pablo, Juan Jose (Proceedings of the National Academy of Sciences, 2015-10-27) Blue phases of liquid crystals represent unique ordered states of matter in which arrays of defects are organized into striking patterns. Most studies of blue phases to date have focused on bulk properties. In this work, we present a systematic study of blue phases confined into spherical droplets. It is found that, in addition to the so-called blue phases I and II, several new morphologies arise under confinement, with a complexity that increases with the chirality of the medium and with a nature that can ...
Dataset on the Marine Sustainability in the United Arab Emirates Gülseven, Osman (Elsevier BV, 2020-08-01) This data compiles the relevant indicators on measuring the UAE's attainments towards sustaining marine life and coastal ecosystems. Those indicators are compiled from three databases, namely from the United Nations, BertelsmannStiftung (BS) Foundation, and the Ocean Health Index (OHI). While the UN and BS indicators are widely accepted in measuring sustainability, many of the indicators in these databases are ambiguous and incomplete. The data from OHI is complete and offers a better perspective on measuri...
