The effect of quantum memory on quantum games

We study quantum games with correlated noise through a generalized quantization scheme. We investigate the effects of memory on quantum games, such as Prisoner's Dilemma, Battle of the Sexes and Chicken, through three prototype quantum-correlated channels. It is shown that the quantum player enjoys an advantage over the classical player for all nine cases considered in this paper for the maximally entangled case. However, the quantum player can also outperform the classical player for subsequent cases that can be noted in the case of the Battle of the Sexes game. It can be seen that the Nash equilibria do not change for all the three games under the effect of memory.Comment: 26 pages, 7 ps figure

Quantum Games with Correlated Noise

We analyze quantum game with correlated noise through generalized quantization scheme. Four different combinations on the basis of entanglement of initial quantum state and the measurement basis are analyzed. It is shown that the advantage that a quantum player can get by exploiting quantum strategies is only valid when both the initial quantum state and the measurement basis are in entangled form. Furthermore, it is shown that for maximum correlation the effects of decoherence diminish and it behaves as a noiseless game.Comment: 12 page

Efficacy of fertilizing method for different potash sources in cotton (Gossypium hirsutum L.) nutrition under arid climatic conditions

Precise choice of potassium (K) source and application method does matter for its cost-effectiveness. This study was aimed to evaluate the best source and method of K fertilizer application to improve cotton productivity and profitability under an arid climate. Three different K sources (KNO3, K2SO4 and KCl) were applied at 100 kg ha-1 by four methods, i.e. a) basal application, b) side dressing, c) fertigation and d) foliar application of 2% K2SO4. The highest productivity and profitability were recorded with K2SO4 applied as foliar application. Total boll weight per plant was similar in foliar applied K2SO4 and basal application of KNO3. Better boll opening in foliar applied K2SO4, perhaps, played decisive role for increased seed-cotton yield. For basal application and side dressing, KNO3 produced the highest seed-cotton yield, but the benefit cost ratio was better for foliar applied K2SO4. In crux, foliar application of K2SO4 might be opted to improve the seed cotton yield, fiber quality and net returns under the arid climate. However, soil K application through K2SO4 and/or KNO3 is essential to balance the K removal from soil

Foliage applied zinc ensures better growth, yield and grain biofortification of mungbean

This study was carried out to optimize the zinc (Zn) foliar application for improving mungbean (Vigna radiata (L.) Wilczek) grain yield and its biofortification. The plants were either sprayed with distilled water, or with Zn solution (0.50, 1.0 and 1.5%) using ZnSO 4 .7H 2 O as source while no spray was also taken as control. Zn foliar application improved the seedling growth, morphological and yield parameters, grain yield and grain Zn concentration in mungbean. Among the various foliar treatments, Zn foliar application at 0.5% was the most effective in improving the root system (longer roots with more roots proliferation), seedling growth, chlorophyll contents, yield related paramet ers, and grain yield; while for grain Zn concentration foliar applied Zn at 1% was effective. Zn application at 0.5 and 1% increased the grain yield and grain Zn concentration by 86 – 38% and 78 – 156%, respectively than no application. Thus, Zn may be foliar applied at 0.5 – 1% for harvesting good grain yield and Zn - enriched grains of mungbean

2-[(2-Chloro­benzyl­idene)amino]-4,5,6,7-tetra­hydro-1-benzothio­phene-3-carbonitrile

In the title compound, C16H13ClN2S, the mean planes fitted through all non-H atoms of the heterocyclic five-membered and the benzene rings are oriented at a dihedral angle of 5.19 (7)°. In the crystal, a weak C—H⋯π inter­action occurs, along with weak π–π inter­actions [cenroid–centroid distance = 3.7698 (11) Å]

4-[(Anthracen-9-yl­methyl­idene)amino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one

In the title compound, C26H21N3O, the phenyl ring of the 4-amino­anti­pyrine group and the heterocyclic five-membered ring along with its substituents, except for the N-bound methyl group (r.m.s. deviation = 0.0027 Å), form a dihedral angle of 54.20 (5)°. Two S(6) ring motifs are formed due to intra­molecular C—H⋯N and C—H⋯O hydrogen bonds. In the crystal, mol­ecules are linked into supra­molecular chains along the a-axis direction via C—H⋯O contacts

Impacts of the integration of Chinese managers in the Western economies the case of Brazil

The Chinese rise to economic and political power at the global level has been at the centre of scholarly and political debates. The purpose of this article will be to analyse the integration of Chinese managers in the Western economy. The methodology will be a bibliography, descriptive, and explanatory, making a comparison between the Brazilian trade and China. The type of literature review is the integrative one, intending to conduct a meta-analysis of the literature and answer specific research questions. The conclusions explore some normative implications of the results of the economy in China and Brazil. On the one hand, China has become a dominant and undeniable shareholder in multiple industries, including the energy sector and R&D with high governmental investments. However, the West appears not to be appropriating its business practices, so the learning process is not fully operationalised.info:eu-repo/semantics/acceptedVersio

A knowledge based decision support system for tool changeover in CNCs

This paper describes an application of an adaptive planning system for automatic tool changers in flexible manufacturing systems. The conventional models of predictive control usually cannot adapt to a real time dynamic environment. The proposed adaptive control model is capable of self adjusting to changing environments. The algorithm is based on a decision logic, which is constructed by breaking up knowledge and converting them into mathematical form in order to cover all possible conditions that can exist during the implementation phase. Expert thoughts and knowledge from decision logic are stored in the decision tree, which consists of circular nodes, arcs and decision nodes. The suggested system is capable of accepting further rules, new nodes and branches to the tree when additional attributes are needed. This whole knowledge is encoded in the form of production rules and each rule represents a small chunk of knowledge relating to the given domain of tool replacement. A number of related rules collectively respond to highly useful conclusions.The system uses VP Expert development shell, contains an inference engine and, a user interface. The originality of the proposed strategy lies in that a knowledge-based expert system is developed to identify and analyze the current conditions and then readjust the output that reflects the real-time environment. Compared with the various classical models, the approach can synthesize and analyze as many variables as possible to adequately and reliably identify the real-time conditions. Simulation results demonstrate the effectiveness and practicality of this tool-change planning and control strategy
