Hybrid Quantum Cloning Machine

Abstract: In this work, we introduce a special kind of quantum cloning machine called Hybrid quantum cloning machine. The introduced Hybrid quantum cloning machine or transformation is nothing but a combination of pre-existing quantum cloning transformations. In this sense it creates its own identity in the field of quantum cloners. Hybrid quantum cloning machine can be of two types: (i) State dependent and (ii) State independent or Universal. We study here the above two types of Hybrid quantum cloning machines. Later we will show that the state dependent hybrid quantum-cloning machine can be applied on only four input states. We will also find in this paper another asymmetric universal quantum cloning machine constructed from the combination of optimal universal B-H quantum cloning machine and universal anti-cloning machine. The fidelities of the two outputs are different and their values lie in the neighborhood of ${5/6} $

Data structures for range-aggregation over categories

Abstract: We solve instances of a general class of problems defined as follows: Preprocess a set S of possibly weighted colored geometric objects (e.g. points/orthogonal segments/rectangles) in IRd, d ≥ 1 such that given a query orthogonal range q (e.g. hyperbox/point), we can report efficiently for each distinct color c of the points in S ∩ q, the tuple where is a function (e.g. weighted sum, bounding box etc.) of the objects of color c in q.

Mg-WC Nanocomposites—Recent Advances and Perspectives

Abstract: Present study summarizes various aspects like fabrication route, microstructural characteristics, mechanical properties, tribological properties of Mg nanocomposites. This study yields that fabrication route plays important role to achieve equiaxed distribution of reinforcement in matrix phase. Mg-MMNCs are developed through different production routes, while main distinction is the matrix state. Among different procedures, liquid metallurgy process is widely accepted due to its simplicity, industrial scalability and cost effectiveness. Effect of incorporation of nanoparticles on microstructure, mechanical properties and tribological properties are revealed by discussing literatures. Special emphasis is given on Mg-WC metal matrix nanocomposites. Effect of WC particles on microhardness, rockwell hardness, ultimate tensile strength and yield strength are also discussed in detail. Finally, wear mechanisms related to different experimental conditions are also mentioned.

Parametric sensitivity of pH and steady state multiplicity in a continuous stirred tank bioreactor (CSTBR) using a lactic acid bacterium (LAB), Pediococcus acidilactici

Abstract: BACKGROUND A continuous stirred tank bioreactor (CSTBR) represents an open dynamic system with high probability to show nonlinear behavior such as parametric sensitivity and multiplicity of steady state. A priori determination of this behavior is needed to decide on the strategy of reactor operation. RESULTS The growth of a lactic acid bacterium, namely, Pediococcus acidilactici in a 2 L CSTBR is used to demonstrate the existence of parametric sensitivity of pH and the multiplicity of steady state in the system. A mathematical model has been developed and a dimensionless multiplicity criterion, ω, has been derived to indicate the set of values of input parameters corresponding to multiple steady states. Experiments have been conducted to study parametric sensitivity of pH with respect to input variables, namely, dilution rates and concentrations of nutrient and alkali stream for pH control in the regions of multiple and unique steady states. The CSTBR exhibited parametric sensitivity of pH over the entire region of operation under study. The experimental trends of parametric sensitivity of pH are also in agreement with those of theoretical parametric sensitivity of pH. CONCLUSION The nonlinear behavior of a CSTBR has been thoroughly portrayed in this article. The present study will add to the knowledge of control and operational strategies of CSTBRs. © 2015 Society of Chemical Industry
