New Class

In this paper, a new class of continuous distributions with two extra positive parameters is introduced and is called the Type II General Exponential (TIIGE) distribution. Some special models are presented. Asymptotics, explicit expressions for the ordinary and incomplete moments, moment residual life, reversed residual life, quantile and generating functions and stress-strengh reliability function are derived. Characterizations of this family are obtained based on truncated moments, hazard function, conditional expectation of certain functions of the random variable are obtained. The performance of the maximum likelihood estimators in terms of biases, mean squared errors and confidence interval length is examined by means of a simulation study. Two real data sets are used to illustrate the application of the proposed class.

Potential Inhibitors

ABSTRACTA variety of 1β-methylcarbapenem derivatives were screened to identify inhibitors of IMP-1 metallo-β-lactamase, a class B β-lactamase, in an automated microassay system using nitrocefin as a substrate. The structure–inhibitory-activity relationship study revealed that three types of 1β-methylcarbapenems having benzothienylthio, dithiocarbamate, or pyrrolidinylthio moieties at the C-2 position showed good inhibitory activity. Among the compounds screened, J-110,441, having a benzothienylthio moiety at the C-2 position of 1β-methylcarbapenem, was the most potent inhibitor of class B metallo-β-lactamases withKivalues of 0.0037, 0.23, 1.00, and 0.83 μM for IMP-1 encoded by theblaIMPgene, CcrA fromBacteroides fragilis, L1 fromStenotrophomonas maltophilia, and type II fromBacillus cereus, respectively. In a further characterization study, J-110,441 also showed inhibitory activity against TEM-type class A serine β-lactamase and chromosomal class C serine β-lactamase fromEnterobacter cloacaewithKivalues of 2.54 and 0.037 μM, respectively. Combining imipenem or ceftazidime with J-110,441 had a synergistic effect on the antimicrobial activity against β-lactamase-producing bacteria. Against the isolates of IMP-1-producingSerratia marcescens, the MICs of imipenem decreased to levels ranging from 1/64 to 1/4 in the presence of one-fourth of the MIC of J-110,441. AgainstE. cloacaeproducing high levels of class C β-lactamase, the MIC of ceftazidime decreased from 64 to 4 μg/ml in the presence of 4 μg of J-110,441 per ml. This is the first report to describe a new class of inhibitor of class B and class C β-lactamases including transferable IMP-1 metallo-β-lactamases.

In this paper, we introduce a new class of generalized bi-quasi-variational inequalities for quasipseudo- monotone type II operators in non-compact settings of locally convex Hausdorff topological vector spaces and show the existence results of solutions for generalized bi-quasi-variational inequalities. Our results improve, extend and generalized the corresponding results given by some authors

Trapped Magnetic Field

ABSTRACTFor type II superconductors (SC), magnetic field can be trapped, or pinned due to persistent internal current. Upon magnetization, SC samples behave in some ways similar to a metallic permanent magnet. The trapped field is high and quasi-persistent, and we refer to it as a “magnet replica”. So far, nearly 1T @ 65 K, and over 0.4 T @ 77 K have been measured within small (about 1 × 1 × 0.6 cm3) melt-textured Yba2Cu3Ox (MT-Y123) samples. Based on our theoretical studies, extrapolation to larger scale magnets indicates that 2–4 Tesla in liquid Nitrogen (and even larger field at lower temperatures) is achievable with our high temperature superconductor (HTS) material. Using this effect, magnets with dipole, quadrupole, or more complicated configurations can be made of existing MT-Y123 material, thus bypassing the need for HTS wires. Two types of motors have been successfully constructed, using the trapped field in MT-Y123 samples.The spatial distribution of the trapped magnetic field on MT-Y123 materials has been studied. A phenomenological model has been developed to account for the trapped field intensity and profile in HTS samples. General features of magnet replicas by HTS will also be discussed.
