Recovery rates from Middlebrook 7H11-selective 7H11 biplates and Lowenstein-Jensen slants (LJ) used with BACTEC 12B vials were compared for 5,399 specimens. For 578 specimens that were inoculated onto three media, 580 mycobacteria were isolated, including 277 (48%) Mycobacterium avium complex isolates, 230 (40%) Mycobacterium tuberculosis isolates, and 73 (12%) other mycobacteria. For BACTEC 12...

The most important objectives in portfolio management are to have the highest average return at a certain level of risk and eliminate unsystematic through diversification. Measuring performance their portfolios has an place investment decisions for investors who want maximum risk. In order measure performance, there three basic methods; Sharpe Ratio, Treynor Ratio Jensen’s Alpha indices. this s...
Early diagnosis of active tuberculosis remains an elusive challenge. In addition, one third of the world's population is latently infected with Mycobacterium tuberculosis (Mtb) and up to 10% of infected individuals develop tuberculosis (TB) in their lifetime. In this investigation, the incidence of urinary tuberculosis among renal patients was studied. Three hundreds urine samples were processe...
Rats were immunized ( 1 ) with Jensen rat sarcoma tissue; ( 2 ) with emulsions of normal rat spleen; ( 3 ) with normal rat blood. Sera from rats of these three series were tested against ( a ) cultures of Jensen rat sarcoma cells; ( b ) cultures of normal spleen cells; (c) cultures of mouse carcinoma 63; ( d ) cultures of cells of normal mouse spleen. Jensen Rat Sarcoma Tissue as Antigen: Two s...
Quantifying the difference between two distributions is a common problem in many machine learning and data mining tasks. What is also common in many tasks is that we only have empirical data. That is, we do not know the true distributions nor their form, and hence, before we can measure their divergence we first need to assume a distribution or perform estimation. For exploratory purposes this ...
فرض کنیم $s_{n}$ گروه متقارن از درجه $n$، $ n>5$ باشد. به ازای جایگشت های غیر همانی و دلخواه $ alpha ,eta in s_{n}$ ثابت می کنیم که $ alpha^{s_{n}}eta^{s_{n}}$ حاصلضرب کلاسهای تزویج $ alpha$ و $eta$ در $s_{n}$، هرگز یک کلاس تزویج نیست. بعلاوه اگر $ n$ فرد باشد و مضربی از 3 نباشد، آنگاه $ alpha^{s_{n}}eta^{s_{n}}$ به صورت اجتماعی از حداقل 3 کلاس ...
Comparative convexity is a generalization of convexity relying on abstract notions of means. We define the (skew) Jensen divergence and the Jensen diversity from the viewpoint of comparative convexity, and show how to obtain the generalized Bregman divergences as limit cases of skewed Jensen divergences. In particular, we report explicit formula of these generalized Bregman divergences when con...
