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

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

Green synthesis of silver nanoclusters via Melia azedarach plant and their potential towards catalytic reduction of 4-nitrophenol

Biomolecules present in the plant extracts have potential to reduce metal ions to nanoclusters by a single-step green synthesis approach. In the current study, we have synthesized the silver nanoclusters (AgNCs) from a medicinal plant, Melia azedarach and studied their catalytic activity toward the reduction of 4-nitophenol to 4-aminophenol and organic dyes. Morover, the phytochemical analysis of the plant extract was carried out in order to determine the bioactive compounds present in it. Metallic nature of the synthesized AgNCs was verified by X-ray diffraction study, while their morphology and size of was confirmed by transmission electron microscopy and Zetasizer, respectively. The study revealed that they were 56±2 nm in size and formed clusters. Fourier transformed infrared spectroscopy gives information about the different functional groups present in synthesized these NCs. Furthermore, the important catalytic applications, such as catalytic reduction of 4-nitrophenol in the presence of mild reducing agent NaBH4 and the catalytic degradation of organic dyes was monitored by FTIR. Therefore, these results indicate that the obtained nanomaterials have important applications in industrial areas.                     KEY WORDS: Green synthesis, Silver nanoclusters, Catalytic reduction, Characterization   Bull.

Genomic affinity between Oryza sativa and Oryza brachyantha as revealed by in situ hybridization and chromosome pairing

Genomic affinity between Oryza sativa (2n = 24 AA), and Oryza brachyantha (2n = 24 FF) was assessed by using three strategies: genomic in situ hybridization (GISH), meiotic chromosome pairing, pollen andspikelet sterility. The chromosome pairing was examined in pollen mother cells of O. brachyantha, O.sativa and the hybrid between O. sativa and O. brachyantha. The hybrid was highly sterile with no pollen stain ability. Both parents showed regular meiosis with normal chromosome pairing. The F1hybrid exhibited limited chromosome pairing. On an average, 0-2 bivalents and 20-24 univalents were recorded at metaphase-1 and 0 - 1 univalent at diakinesis. The most frequent configuration was twobivalents and twenty univalent. The meiosis was highly irregular showing unequal distribution of chromosomes at anaphase, formation of multipolar bodies and variation in the cell cycle of both genomes. GISH revealed unequivocal discrimination of O. brachyantha chromosomes as appeared red from O. sativa chromosomes that fluoresced yellow. No cross hybridization was examined between the labeled genomic DNA of O. brachyantha and the chromosomes of O. sativa. Mitotic chromosomes of O. brachyantha and O. sativa, in the hybrid, were discriminated by GISH. High sterility in this hybrid could be due to abnormal meiosis and lack of pairing

Dilemma and Quantum Battle of Sexes

We analysed quantum version of the game battle of sexes using a general initial quantum state. For a particular choice of initial entangled quantum state it is shown that the classical dilemma of the battle of sexes can be resolved and a unique solution of the game can be obtained.Comment: Revised, Latex, 9 pages, no figure, corresponding author's email: [email protected]

Individual knowledge management engagement, knowledge-worker productivity, and innovation performance in knowledge-based organizations: the implications for knowledge processes and knowledge-based systems

The literature on the knowledge management relatively ignores an important concept, the individual knowledge management engagement-the degree to which a knowledge worker is involved with the knowledge management-related activities. This concept is imperative for nurturing the productivity of knowledge workers, knowledge management architecture effectiveness, and innovation. Therefore, this study proposes the mediating role of knowledge-worker productivity between individual knowledge management engagement and innovation. The data were collected from the 330 knowledge workers of IT sector of Pakistan and analyzed using the SmartPLS 3 Version 2.6. The results indicate the partial mediation of knowledge-worker productivity between the individual knowledge management engagement and innovation. The results suggest the pivotal role of individual knowledge management engagement in increasing the innovation and knowledge-worker productivity in the knowledge-based organizations.info:eu-repo/semantics/publishedVersio

Effect of different tillage implements and gypsum for fodder production in salt affected soils using high RSC water

Selection of suitable tillage implement, as well as amendments, is very important for the reclamation of salt affected soils. For this purpose, a field study was performed using the different rates of gypsum and tillage implements for the production of sorghum and berseem fodders in salt affected field using high RSC water. Treatments including were T1: control (cultivator twice), T2: modified chisel plough (twice), T3: chisel plough (twice), T4: modified chisel plough (twice) + gypsum application @ 100% GR of soil, T5: modified chisel plough (twice) + gypsum application @ 50% GR of soil, T6: chisel plough (twice) + gypsum application @ 100% GR of soil, T7: chisel plough (twice) + gypsum application @ 50% GR of soil. A moderately salt affected field {ECe = 5.37 (d Sm-1), pHs = 9.18, SAR = 34.01 (m mol L-1)1/2 and GR 3.10 t acre-1} was selected. Field was leveled, prepared and gypsum was applied according to treatment plan, followed by leaching. Tubewell water {ECiw= 1.34 dS m-1, RSC= 8.50 me L-1 and SAR= 12.72 (mmol L-1)1/2} was used for irrigation. Gypsum was also applied before sowing of each crop on RSC basis of water. The trial was performed in the RCBD design with three replications. Pooled data of three years showed that maximum fodder yield of sorghum (38.44 t ha-1) and berseem (60.21 t ha-1) was recorded with modified chisel plough (twice) + gypsum @ 100% GR of soil. Data regarding the soil qualities revealed that soil pHs, ECe, SAR and BD decreased by 4.24, 30.72 and 31.37, respectively, while HC was increased by 130 % with use of modified chisel plough (twice) + gypsum @ 100% GR of soil, as compared to control
