Two-dimensional (2D) Dirac fermions are a central paradigm of modern condensed matter physics, describing low-energy excitations in graphene, certain classes superconductors, and on surfaces 3D topological insulators. At zero energy E=0, with mass m band insulators, the Chern number jumping by unity at m=0. This observation lead Ludwig et al [Phys. Rev. B 50, 7526 (1994)] to conjecture that tra...
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will detect an unprecedentedly large sample actively accreting supermassive black holes with typical accretion disk (AD) sizes a few light days. This brings us to face challenges in the reverberation mapping (RM) measurement AD active galactic nuclei (AGNs) using interband continuum delays. We examine effect LSST cadence strat...
This study assesses the effect of mix design parameters on fresh and hardened properties, cost, carbon footprint geopolymer mortar made with desert dune fines (DDF) blast furnace slag (BFS). Taguchi method was employed in designing experiments. Four factors were considered, each having three levels, leading to a total nine mixes. The comprised DDF replacement percentage, alkali-activator soluti...
This paper develops a new factor-analysis-based (FAB) approach for choosing the optimal direction in directional distance function (DDF) analysis. It has combined merits of factor analysis and slacks-based measure (SBM) incorporates relative ease with which various input-output could be adjusted. development relieves reliance on price information that is difficult to obtain provision public goo...
A regional probabilistic model for the estimation of medium-high return period flood quantiles is presented. The model is based on the use of theoretically derived probability distributions of annual maximum flood peaks (DDF). The general model is called TCIF (Two-Component IF model) and encompasses two different threshold mechanisms associated with ordinary and extraordinary events, respective...
This paper suggests refinements and extensions of the JDL Data Fusion Model, the standard process model used for a multiplicity of community purposes. However, this Model has not been reviewed in accordance with (a) the dynamics of world events and (b) the changes, discoveries, and new methods in both the data fusion research and development community and related IT technologies. This paper sug...
Laminitis is the second most common cause of death from disease in horses and causes great suffering animal economic emotional losses for people involved. Several therapeutic modalities are used treatment this disease, but their results not consistently described literature. In scenario, deep digital flexor (DDF) tenotomy a modality that can be chronic laminitis, releasing traction force DDF te...
OBJECTIVE Our aim was to evaluate the long-term effects of transplanted islets on diabetic macro-/microangiopathy in type 1 diabetic kidney-transplanted patients. RESEARCH DESIGN AND METHODS A total of 34 type 1 diabetic kidney-transplanted patients underwent islet transplantation and were divided into two groups: successful islet-kidney transplantation (SI-K; 21 patients, fasting C-peptide s...
In this paper, we propose novel cooperative transmission protocols for delay limited coherent fading channels consisting of N (half-duplex and singleantenna) partners and one cell site. In our work, we differentiate between the relay, cooperative broadcast (down-link), and cooperative multiple-access (up-link) channels. The proposed protocols are evaluated using Zheng-Tse diversity-multiplexing...
