    Inequivalent Leggett-Garg inequalities

    It remains an open question how realist view of macroscopic world emerges from quantum formalism. For testing the macrorealism in quantum domain, an interesting approach was put forward by Leggett and Garg in 19851985, by formulating a suitable inequality valid for any macrorealistic theory. Recently, by following the Wigner idea of local realist inequality, a probabilistic version of standard Leggett-Garg inequalities have also been proposed. While the Wigner form of local realist inequalities are equivalent to the two-party, two-measurements and two outcomes CHSH inequalities, in this paper we provide a generic proof to demonstrate that the Wigner form of Leggett-Garg inequalities are not only inequivalent to the standard ones but also stronger than the later. This is demonstrated by quantifying the amount of disturbance caused by a prior measurement to the subsequent measurements. In this connection, the relation between LGIs and another formulation of macrorealism known as no-signaling in time is examined.Comment: Close to the published version. arXiv admin note: text overlap with arXiv:1705.0993

    Insulator superconductor transition on solid inert gas substrates

    Full text link
    We present observations of the insulator-superconductor transition in ultrathin films of Bi on solid xenon condensed on quartz and on Ge on quartz. The relative permeability ϵr\epsilon_{r} ranges from 1.5 for Xe to 15 for Ge. Though we find screening effects as expected, the I-S transition is robust, and unmodified by the substrate. The resistance separatrix is found to be close to h/4e2h/4e^2 and the crossover thickness close to 25 A˚\AA for all substrates. I-V studies and Aslamazov-Larkin analyses indicate superconductivity is inhomogeneous. The transition is best described in terms of a percolation model.Comment: Submitted to LT23 Proceeding

    To estimate the level of heat tolerance for different genotypes of bread wheat with respect to morphological characters under studied grains/ spike, grain weight/spike, grain filling duration (duration between the anthesis stage and the physiological maturity), 1000-kernel weight and grain yield/plant for yield. Physiological traits like relative injury (RI %), chlorophyll content, canopy temperature depression (CTD), were used in present investigation to contribute toward capability of plants to tolerate heat stress of the yield contributing traits during heat stress.The findings of present investigation had clearly explained that influences of environments on morpho physiological characters i.e. grain yield per plant (14886.15) and its attributing traits i.e. spike length (459.7), tillers per plant (622.34), spikelets per spike (278.1), 1000 kernel weight (13262.39), grain weight per spike (177.89) and number of grains per spike (2898.44) in wheat were highly significant and positive. Among the parent and their crosses had handsome amount of variations across the environment. The results of interaction for environments with parents, lines, testers and their crosses with respect to morpho physiological characters in wheat was found significant for some characters while variation was absent for other characters studied. Physiological traits like relative injury per cent, chlorophyll content and CTD were vital parameters to quantify the degree of heat stress to develop tolerant genotypes which is urgent and present need under changing climate scenario

    VASANTIKAVAMANA A PREVENTIVE MEASURE FOR KAPHAJA ROGAS

    The aims and objective of Ayurveda is of two fold i.e., Prevention of disease in healthy individual and cure of the disease in a diseased person. To fulfil the first aim, our Acharyas have described Dinacharya, Rutucharya. In Dosha chaya, Prakopaavastha, if the person consumes more Apathyakaraahara, Vihara, Doshas will go in Prasaraadiavast has and leads to Vyadhi. Ayurveda emphasized to practise these therapies to eliminate the vitiated Dosha in accordance to the seasonal variation like Vamana in Vasantharutu, Virechana in Sharadrutu, Basti in Pravrutrutu, as a prevention of disease and promotion of health. Person who follows this regimen in each season never suffers from severe disorderAccording to Induteeka, thus neglected, the vitiated Dosha get accumulated over the time to its maximum, and the channels of rasa are being obstructed by the vitiated Dosha (deposition of debries in the inner layers making the lumen narrowed), nourishment to the tissues is not possible. This causes the diseases like Sthoulya, Agnisada, Kusta, Meha etc, which are not amenable for treatment. 4 Maasa (Rutudvaya) for Sanchaya of Kaphadosha, if it is not early evacuated in Chaitramaasa it end up in Rutujaan rogas. Hence, while maintaining health itself one must undergo purifactory measures to prevent from occurrence of the diseases by seasonal factors. Hence this conceptual study is made to explain the effect of Vasantikavamana a preventive measure for Kaphaja rogas.

    ROLE OF PADA ABHYANGA AS PREVENTIVE ASPECT W.S.R TO EYE DISORDERS: A CONCEPTUAL STUDY

    Ayurveda aimed in prevention and cure of physical and mental health. In Ayurveda, Dinacharya is one of the concept which helps to fulfill this aim of Ayurveda. Vitality enhancing technique which is incorporated in massage of the feet is called Padabhyanga. It is one of the prophylactic principles mentioned in Ayurvedic dinacharya. The hectic computerised life style, faulty food habits, stress and strain, irregular sleeping habits and negligence in following daily and seasonal regimen provoke many eye problems. By doing Padaabhyanga, Kharatwa, Stabdata, Rukshata, Shrama, Suptata of pada relieved and Bala, Sthairya improved, Drustiprasaadakara. It also prevents Grudrasi vaata, Pada sputana, Sirasnaayu sankocha.In the centre of the feet 2 Siras are situated which are directly connected to the eyes, these transmit the effect of the medicines applied over the feet in the form of massage. Hence every person should need make use of Padabhyanga. Major cause of blindness for prevalence are cataract, glaucoma, diabetic retinopathy, Age related macular degeneration, refractive errors. There by Paada Abhyanga through its Vaata-ameliorating action is responsible for better function of Chakshurindriya. According to Sushrutacharya, by practice of Snehana karma, which results in Utpatti of Pratyagradhatu – Navadhatu. such that degenerative changes related to eye are antagonized by the Snehana karma. Padaabhyanga is helpful in preventing above said diseases which causes the blindness. Hence this conceptual study is made to explain the mode of action and effect of Pada Abhyanga to increase and maintain the visual acuity
