    Lagrangian subcategories and braided tensor equivalences of twisted quantum doubles of finite groups

    Full text link
    We classify Lagrangian subcategories of the representation category of a twisted quantum double of a finite group. In view of results of 0704.0195v2 this gives a complete description of all braided tensor equivalent pairs of twisted quantum doubles of finite groups. We also establish a canonical bijection between Lagrangian subcategories of the representation category of a twisted quantum double of a finite group G and module categories over the category of twisted G-graded vector spaces such that the dual tensor category is pointed. This can be viewed as a quantum version of V. Drinfeld's characterization of homogeneous spaces of a Poisson-Lie group in terms of Lagrangian subalgebras of the double of its Lie bialgebra. As a consequence, we obtain that two group-theoretical fusion categories are weakly Morita equivalent if and only if their centers are equivalent as braided tensor categories.Comment: 26 pages; several comments and references adde

    Small Quadrupole Deformation for the Dipole Bands in 112In

    Full text link
    High spin states in 112^{112}In were investigated using 100^{100}Mo(16^{16}O, p3n) reaction at 80 MeV. The excited level have been observed up to 5.6 MeV excitation energy and spin \sim 20\hbar with the level scheme showing three dipole bands. The polarization and lifetime measurements were carried out for the dipole bands. Tilted axis cranking model calculations were performed for different quasi-particle configurations of this doubly odd nucleus. Comparison of the calculations of the model with the B(M1) transition strengths of the positive and negative parity bands firmly established their configurations.Comment: 10 pages, 11 figures, 2 table

    Doubly Fed Induction Generator for Wind Energy Conversion Systems manages the operation of doubly nourished acceptance generator with an incorporated dynamic channel capacities utilizing network side converter (GSC). The principle commitment of this work lies in the control of GSC for providing sounds notwithstanding its slip control exchange. The rotor-side converter (RSC) is utilized for accomplishing most extreme power extraction and to supply required responsive energy to DFIG. Wind vitality change framework (WECS) functions as a static compensator (STATCOM) for providing music notwithstanding when the wind turbine is in shutdown condition. Control calculations of both GSC and RSC are introduced in detail. Actualized extend DFIG-based WECS is reproduced utilizing MATLAB/Simulink . A model of the proposed DFIG based WECS is produced utilizing a fluffy logic controller. The wind vitality is the favored for all renewable vitality sources. In the underlying days, wind turbines have been utilized as settled speed twist turbines with squirrel confine acceptance generator and capacitor banks. The majority of the wind turbines are settled speed as a result of their straightforwardness and minimal effort

    During field surveys, three peanut green mosaic virus isolates differing in symptomatology on groundnut and a few other hosts were collected. Ultrathin sections of infected groundnut leaflets showed cytoplasmic inclusions with pin wheels and scrolls. In enzyme-linked immunosorbent assay they reacted strongly with antisera to peanut green mosaic and soybean mosaic virus antisera, and moderately with adzuki bean mosaic and peanut stripe virus antisera. All isolates also reacted positively with antisera to peanut eye spot, blackeye cowpea mosaic, pea seed-borne mosaic, potato virus Y and tobacco etch viruses, and did not react with antisera to peanut mottle, bean yellow mosaic, bean common mosaic, clover yellow vein and sugarcane mosaic viruses. SDS-PAGE analysis of purified virus preparations of the three isolates showed a single polypeptide with mol. wt. of 34,500 daltons. Based on these results, the three isolates are identified as biologically distinct strains of peanut green mosaic virus

    A procedure for the purification of TSWV-Tx, a tomato spotted wilt virus isolate infecting groundnuts in Texas, is described. A rabbit antiserum was produced. Several TSWV isolates occurring on groundnuts in the USA reacted to varying extents in ELISA with antisera to TSWV-Tx and to Greek TSWV isolates, but failed to react with antiserum to an isolate of TSWV from India. In reciprocal tests, antigens of the Indian TSWV failed to react with antisera to Tx and to the Greek isolates. Purified TSWV-Tx contained 4 polypeptide species of 78 000, 54 000 and 27 000 Da. In electro-blot immunoassays, all 4 polypeptides reacted with the homologous antiserum and with antisera prepared against a Greek, a Dutch and an Australian isolate. None of the polypeptides reacted with the antiserum to the Indian isolate

    A prospective, multicentre, observational cohort study of analgesia and outcome after pneumonectomy

    Background Meta-analysis and systematic reviews of epidural compared with paravertebral blockade analgesia techniques for thoracotomy conclude that although the analgesia is comparable, paravertebral blockade has a better short-term side-effect profile. However, reduction in major complications including mortality has not been proven. Methods The UK pneumonectomy study was a prospective observational cohort study in which all UK thoracic surgical centres were invited to participate. Data presented here relate to the mode of analgesia and outcome. Data were analysed for 312 patients having pneumonectomy at 24 UK thoracic surgical centres in 2005. The primary endpoint was a major complication. Results The most common type of analgesia used was epidural (61.1%) followed by paravertebral infusion (31%). Epidural catheter use was associated with major complications (odds ratio 2.2, 95% confidence interval 1.1–3.8; P=0.02) by stepwise logistic regression analysis. Conclusions An increased incidence of clinically important major post-pneumonectomy complications was associated with thoracic epidural compared with paravertebral blockade analgesia. However, this study is unable to provide robust evidence to change clinical practice for a better clinical outcome. A large multicentre randomized controlled trial is now needed to compare the efficacy, complications, and cost-effectiveness of epidural and paravertebral blockade analgesia after major lung resection with the primary outcome of clinically important major morbidity

    Morpho-Physiological Parameters Associated with Iron Deficiency Chlorosis Resistance and Their Effect on Yield and Its Related Traits in Groundnut

    Iron deficiency chlorosis (IDC) causes a significant reduction in yield of groundnut grown in calcareous and alkaline soils in India. The main aim of the study was to assess genotypic differences for morpho-physiological parameters associated with IDC resistance across different stages and their effect on yield and its related traits. The factorial pot experiment was comprised of two major factors, i) soil-Fe status [normal-Fe, deficit-Fe], and ii) genotypes [five] with differential IDC response, constituting 10 treatments. They were assessed for five morpho-physiological parameters associated with IDC resistance across five crop growth stages and also yield and its related traits. Associations between these traits were also estimated. Under deficit-Fe conditions, IDC resistant genotypes recorded significantly lower visual chlorosis rating (VCR), higher SPAD values, active Fe, chlorophyll content, peroxidase activity, and high yield compared to susceptible ones. Between normal- to deficit-Fe soils, resistant compared to susceptible genotypes showed no change in VCR scores; a lower reduction in SPAD, chlorophyll, active Fe, peroxidase activity, and pod yield. Under deficit-Fe conditions, high yield among resistant genotypes could be attributed to higher seed weight, number of pods and haulm yield, while contrasting reduction in main stem height and number of primaries. The results indicate that for initial large-scale screening of groundnut genotypes for IDC resistance, SPAD values are most ideal while active Fe could be utilized for confirmation of identified lines
