The CERES/NA45 experiment measures low mass electron pair production in Pb-Au collisions at 158AGeV at the CERN SPS. In this paper, we present the electron pair enhancement in the mass range 0:2 < mee < 0:7 GeV/c 2 , it increases more than linear with charged multiplicity and is most pronounced at low pair pT < 0:5 GeV/c. Transverse mass and rapidity distributions for charged hadrons h + ? h ? ...

The schematic CERES method [?] is a recently developed method of cut elimination for proof schemata, that is a sequence of proofs with a recursive construction. Proof schemata can be thought of as a way to circumvent adding an induction rule to the LK-calculus. In this work, we formalize a schematic version of the infinitary pigeonhole principle, which we call the Non-injectivity Assertion sche...

The mineralogy and geochemistry of Ceres, as constrained by Dawn’s instruments, are broadly consistent with a carbonaceous chondrite (CM/CI) bulk composition. Differences explainable by Ceres’s more advanced alteration include the formation of Mgrich serpentine and ammoniated clay; a greater proportion of carbonate and lesser organic matter; amounts of magnetite, sulfide, and carbon that could ...

Introduction: The main-belt object Ceres (radius≈475 km, density≈2100 kg m-3 , semi-major axis 2.7 AU), is an exciting place to explore planetary hab-itability. Abundant volatiles could have shaped Ceres in a way analogous to that suspected on icy moons. Hydrothermalism: Ceres' surface seems blanketed by products of the interaction between silicate rock and liquid water, including carbonates [1...

In the major reorganisation that took place at Halmstad University during 1999-2000, the new School of Information Science, Computer and Electrical Engineering (IDE) was formed. The School of IDE is divided into five laboratories; Computing and Communication (CC), Electronics and Physics (EF), Intelligent Systems (IS), Mathematics (MA), and Man and Information technology (MI). The division into...

Accurate multidecadal radiative flux records are vital to understand Arctic amplification and constrain climate model uncertainties. Uncertainty in the NASA Clouds Earth’s Radiant Energy System (CERES)-derived irradiances is larger over sea ice than any other surface type comes from several sources. The year-long Multidisciplinary drifting Observatory for Study of Climate (MOSAiC) expedition ce...

Atmospheric downward longwave radiation (DLR) is a key component of the surface energy budget in Earth system. Satellite retrievals and atmospheric reanalysis estimates are two typical approaches to obtaining spatio-temporally continuous DLR product. In this study, we evaluated product from latest ERA5 well-known Clouds Earth's Radiant Energy System (CERES) satellite retrievals, against high-qu...

Maize (Zea mays) has traditionally been a major cereal staple in southern Ghana. Through breeding and other crop improvement efforts, the zone of cultivation of maize has now extended to the northern regions of Ghana which, hitherto, were the home to sorghum and millet as the major cereals. Maize yield in the northern Ghana is hampered by three major biophysical constraints, namely, poor soil f...

Title of dissertation: LIGHT SCATTERING PROPERTIES OF ASTEROIDS AND COMETARY NUCLEI Jian-Yang Li, Doctor of Philosophy, 2005 Dissertation directed by: Professor Michael F. A’Hearn Associate Research Professor Lucy A. McFadden Department of Astronomy The photometric properties of asteroids and cometary nuclei, bodies important for understanding the origin of the Solar System, are controlled by t...

Fusing MODIS, MISR and CERES Satellite Data for Aerosol Research Sundar A. Christopher, Pawan Gupta and Falguni Patadia The University of Alabama in Huntsville Huntsville, AL 35805 [email protected] Abstract Combining data sets from multiple satellite sensors is a powerful method for studying earth-atmosphere problems. By fusing data, we can utilize the strengths of the individual instrument...
