in this paper, non parametric data envelopment analysis (dea) was subjected to the energy data of wheat producers in punjab state, india, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. the main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...

— We review the observational status of the Supernova (SN)/GammaRay Burst (GRB) connection. In section 2 we provide a short summary of the observational properties of core-collapse SNe. In sections 3-6 we review the circumstantial evidences and the direct observations that support the existence of a deep connection between the death of massive stars and GRBs. Present data suggest that SNe assoc...

Let Sn be the set of all permutations on [n] := {1, 2, . . . , n}. We denote by κn the smallest cardinality of a subset A of Sn+1 that “covers” Sn, in the sense that each π ∈ Sn may be found as an order-isomorphic subsequence of some π′ in A. What are general upper bounds on κn? If we randomly select νn elements of Sn+1, when does the probability that they cover Sn transition from 0 to 1? Can w...

The iron mass in galaxy clusters is about 6 times larger than could have been produced by core-collapse SNe, assuming the stars in cluster galaxies formed with a standard IMF. Type-Ia SNe have been proposed as the alternative dominant iron source. We use our HST measurements of the cluster SN-Ia rate at high redshift to study the cluster iron enrichment scenario. The measurements can constrain ...

OBJECTIVES To determine the feasibility of sentinal lymph node (SN) radiolocalization and to assess the cost-effectiveness of the SN navigation surgery strategy in patients with stage N0 squamous cell carcinoma (SCC) of the head and neck. Patients Eleven consecutive patients with stage N0 SCC of the head and neck. METHODS Head and neck lymphoscintigraphy was performed 2 hours after the inject...

212 MAX phase borides are new additions to the family with enhanced thermo-mechanical properties. In this article, first-principles calculations have been carried out explore mechanical properties, Vickers hardness, elastic anisotropy, thermal and optical properties of predicted thermodynamically stable compounds Hf2AB2 (A = In, Sn). The structural compared available data assess validity calcul...

Accurate constraints on curvature provide a powerful probe of inflation. However, based specific assumptions dark energy may lead to unreliable conclusions when used test inflation models. To avoid this, it is important obtain that are independent for energy. In this paper, we investigate such from the geometrical constructed galaxy-lensing cross-correlations. We study comprehensively cross-cor...

CONTEXT There is no rapid and cost effective tool that can be implemented as a front-line screening tool for Alzheimer's disease (AD) at the population level. OBJECTIVE To generate and cross-validate a blood-based screener for AD that yields acceptable accuracy across both serum and plasma. DESIGN, SETTING, PARTICIPANTS Analysis of serum biomarker proteins were conducted on 197 Alzheimer's ...

A cooperative cognitive radio scheme exploiting primary signals for energy harvesting is proposed. The relay sensor node denoted as the secondary transmitter (ST) harvests energy from the primary signal transmitted from the primary transmitter, and then uses it to transmit power superposed codes of the secrecy signal of the secondary network (SN) and of the primary signal of the primary network...

Tin and titanium pentenoate have been prepared from tin(IV) butoxide and titanium (IV) isopropoxide in alcohol and 3-pentenoic acid. Reactions of Sn(OBu n )4 and Ti(OPr i )4 with 3-pentenoic acid in 1:1 molar ratio were studied in butanol and propanol solution at room temperature by sol-gel process. The complexations were investigated by 13 C, 1 HNMR and FT-IR spectroscopy. 13 C{ 1 H}, 1 H-NMR ...
