Cut-elimination is one of the most famous problems in proof theory, and it was defined and solved for first-order sequent calculus by Gentzen in his celebrated Hauptsatz. Ceres is a different cut-elimination algorithm for firstand higher-order classical logic. It is based on the notion of a characteristic set of clauses which is extracted from a proof in sequent calculus and is always unsatisfi...
A study of the time evolution of GERB shortwave calibration by comparison with CERES Edition-3A data
Article history: Received 14 January 2016 Received in revised form 8 August 2016 Accepted 7 September 2016 Available online xxxx This study examines the evolution of the GERB-2 and GERB-1 Edition 1 shortwave radiance calibration between 2004–2007 and 2007–2012 respectively, through comparisonwith CERES instrument FM1Edition 3A SSF instantaneous radiances. Two periods when simultaneous observati...
On 6 March 2015, Dawn arrived at Ceres to find a dark, desiccated surface punctuated by small, bright areas. Parts of Ceres' surface are heavily cratered, but the largest expected craters are absent. Ceres appears gravitationally relaxed at only the longest wavelengths, implying a mechanically strong lithosphere with a weaker deep interior. Ceres' dry exterior displays hydroxylated silicates, i...
We present a global spectrophotometric characterization of the Ceres surface using Dawn Framing Camera (FC) images. We identify the photometric model that yields the best results for photometrically correcting images. Corrected FC images acquired on approach to Ceres were assembled into global maps of albedo and color. Generally, albedo and color variations on Ceres are muted. The albedo map is...
[1] Spectrally resolved outgoing thermal-IR flux, the integrand of the outgoing longwave radiation (OLR), has a unique value in evaluating model simulations. Here we describe an algorithm for deriving such clear-sky outgoing spectral flux through the entire thermal-IR spectrum from the collocated Atmospheric Infrared Sounder (AIRS) and the Clouds and the Earth’s Radiant Energy System (CERES) me...
Aims. We study the physical characteristics (shape, dimensions, spin axis direction, albedo maps, mineralogy) of the dwarf-planet Ceres based on high-angular resolution near-infrared observations. Methods. We analyze adaptive optics J/H/K imaging observations of Ceres performed at Keck II Observatory in September 2002 with an equivalent spatial resolution of ∼50 km. The spectral behavior of the...
Cut-elimination is the most important proof transformation in logic. Equality is a central paradigm in mathematics and plays a key role in automated deduction. Therefore its importance awakes the necessity of integrating equality into existing cut-elimination methods. In this paper we extend the resolution-based method of cut-elimination CERES to CERES-e by adding equality (and paramodulation t...
The surface elemental composition of dwarf planet Ceres constrains its regolith ice content, aqueous alteration processes, and interior evolution. Using nuclear spectroscopy data acquired by NASA's Dawn mission, we determined the concentrations of elemental hydrogen, iron, and potassium on Ceres. The data show that surface materials were processed by the action of water within the interior. The...
Climate change impacts the sustainability of agriculture. Physiological processes are very essential for improving crop modeling. The objective this paper was to assess integrated effects modeling and physiology on response rice climate change. Some models have weakness rectified by better understanding physiological features which is correlated growth development plant. Process-based dynamic a...
The manuscript describes the methodology employed to derive the current angular distribution models (ADMs) for the CERES instruments, i.e. the radiance-to-flux conversion algorithms for CERES thermal and solar measurements. This paper is necessary to document the new CERES product Ed4SSF, which improves the retrieval of cloud parameters and TOA flux with respect to previous versions. The enhanc...
