    Polaritonic characteristics of insulator and superfluid phases in a coupled-cavity array

    Full text link
    Recent studies of quantum phase transitions in coupled atom-cavity arrays have focused on the similarities between such systems and the Bose-Hubbard model. However, the bipartite nature of the atom-cavity systems that make up the array introduces some differences. In order to examine the unique features of the coupled-cavity system, the behavior of a simple two-site model is studied over a wide range of parameters. Four regions are identified, in which the ground state of the system may be classified as either a polaritonic insulator, a photonic superfluid, an atomic insulator, or a polaritonic superfluid.Comment: 7 pages, 9 figures, 1 table, REVTeX 4; published versio

    Dynamics in a coupled-cavity array

    Full text link
    The dynamics of a system composed of two coupled optical cavities, each containing a single two-level atom, is studied over a wide range of detuning and coupling values. A description of the field in terms of delocalized modes reveals that the detuning between the atoms and these modes is controlled by the coupling between the cavities; this detuning in turn governs the nature of the dynamics. If the atoms are highly detuned from both delocalized field modes, the dynamics becomes dispersive and an excitation may be transferred from the first atom to the second without populating the field. In the case of resonance between the atoms and one of the delocalized modes, state transfer between the atoms requires intermediate excitation of the field. Thus the interaction between the two atoms can be controlled by adjusting the coupling between the cavities.Comment: 11 pages, 3 figure

    Combined immunosuppressive therapy with low dose FK506 and antimetabolites in rat allogeneic heart transplantation

    Following rat heterotopic heart allotransplantation, low to lethal doses of the antimetabolites mizoribine (MIZ), RS-61443 (RS), and AZA were given alone or in combination with subtherapeutic doses of FK506 (0.04 mg/kg/day) for 14 days after transplantation. With the median effect analysis of Chou and Kahan for quantitative drug interactions, substantial therapeutic synergism was demonstrated between FK506 and nontoxic doses of MĪZ (2.5, 5, and 10 mg/kg/day) or AZA (5, 30, and 45 mg/kg/day), which was particularly evident with the lowest dose MIZ (2.5 mg/kg/day). When FK506 was used in combination with MIZ or AZA but not with RS, the maximum effect (peak median graft survival) was enhanced significantly from 15 days (MIZ alone) to 26 days (P<0.05), and from 19 days (AZA alone) to 32 days (P<0.0l). In contrast, RS interacted with FK506 no more than additively. Although RS was the most powerful single antimetabolite, the best overall survival was obtained by combining AZA and FK506. The addition of FK506 did not significantly increase the percent mortality and LD50 of the antimetabolites. © 1994 by Williams and Wilkins

    Can adenine nucleotides predict primary nonfunction of the human liver homograft?

    Sixty-eight primary liver grafts were analyzed to see whether adenine nucleotides (AN: ATP, ADP, and AMP) or purine catabolites (PC: adenosine, inosine, hypoxanthine, and xanthine) of tissue or effluent can predict primary graft nonfunction. AN, PC, and nicotinamide adenine dinucleotide, oxidized form (NAD+) of the tissue before (pretransplant) and after graft reperfusion (post-transplant) and of the effluent were analyzed. The graft outcome was classified into two groups (group A: successful, n = 64; group B: primary nonfunctioning, n = 4). No significant differences were observed in pretransplant measurements between groups A and B, whereas ATP, ADP, total AN, total AN + total PC (T) and NAD+, in post-transplant tissues, were significantly higher in group A. Xanthine in the effluent was significantly higher in group B than in group A. ATP, ADP, total AN, T, and NAD+ in post-transplant tissue were significantly associated with primary graft nonfunction by logistic regression analysis

    Social Responsibility Of Private Higher Educational Sector Towards The Teaching Faculties

    Sensitization of staff is one of the fundamental agenda behindhand of social responsibility when focused from any view. Recent years we could find emerging of many universities and colleges in and around globally. According to the UGC (University Grants Commission) Feb 2020 list, India has 935 universities includes 409 state universities, 349 private universities, 50 central universities and 127 deemed to be universities. In India, colleges and universities play a vital role in societies. Also from the Educational Statistics at A Glance (ESAG) survey published by Ministry of Human Resource Development, Department of School Education & Literacy Statistics Division, the study discovers that the number of private universities increases every year. Due to the decrease in the government financial support and lack of initiating the steps to make our higher education globalization, education has now been commercialized as required to house themselves in this capitalized market. This change has not only impacted the curricular edition but has also decreased the concept of social responsibility. This paper aims to bring out the challenges and discuss how universities can attain charity, sustainability and provide financial support at time of need. The study used both the primary and secondary data survey to find out the percentage of satisfactory level among the employers who are directly involved to the university
