In this paper, we propose a new two-parameter biased estimator in gamma regression models when there is collinearity among the regressors. We investigate mean squared error (MSE) properties of newly proposed estimator. Moreover, provide some theorems to compare estimators existing ones. conduct Monte Carlo simulation study under different designs sense MSE. real data application show usefulness...

Peripheral blood cells from 29 patients with active Mycobacterium avium (MAC) or Mycobacterium tuberculosis diseases were tested for mycobacterial antigen-induced interferon (IFN)-gamma and interleukin (IL)-4 production. Among MAC patients, human immunodeficiency virus (HIV) infection was associated with an 80% decrease in those who produced IFN-gamma, resulting in a predominantly type 2 cytoki...

DNA microarray analyses were used to investigate the effect of cell-incorporated 35S-methionine on human colorectal carcinoma cells. This beta-radiation-induced gene expression profile was compared with that induced by external gamma-radiation. The extent of DNA fragmentation was used as a biomarker to determine the external gamma dose that was bioequivalent to that received by cells incubated ...

In the discussion that follows, we assume that gamma rays are the radiation of interest. The principles discussed also apply to monoenergetic x rays; in many cases of concern in x-ray shielding, however, the photons are produced in the bremsstrahlung process that yields a wide and continuous distribution of photon energies. Specialized shielding approaches have been developed to carry out shiel...

Background: Brucellosis is the major bacterial zoonoses of global importance caused by Brucella spps. FCγRIIA receptor plays a central role in phagocytosis of IgG2-opsonized bacteria. FCγRIIA exhibits allelic polymorphisms with different capacities for binding IgG2 and phagocytosis. Cells expressing Fc γ RIIa-H131, bind more efficiently to complexes of IgG2 than those expressi...

We calculate the absorptive part of photon polarization tensor in a hot magnetized relativistic plasma. In derivation, we utilize Landau-level representation for fermion Green's function mixed coordinate-momentum space and obtain closed-form expression one-loop tensor. At leading order coupling, its is determined by particle antiparticle splitting processes ($e^{-} \leftrightarrow e^{-}+\gamma$...
