In assessing the efficacy of a time-varying treatment Marginal Structural Models (MSMs) and Structural Nested Mean Models (SNMMs) are useful in dealing with confounding by variables affected by earlier treatments. MSMs model the joint effect of treatments on the marginal mean of the potential outcome, whereas SNMMs model the joint effect of treatments on the mean of the potential outcome condit...

Among scheduling algorithms used in input queued switches, it is known that the Maximum Size Matching (MSM) algorithm maximizes the instantaneous throughput. Although there have been results on the stability of some specific types of MSMs for scheduling traffic [5], the question of how it performs under uniform traffic remains open. Simulations suggest the stability of MSM algorithms under unif...

Methods Immunodominant regions of 3 Mycobacterium tuberculosis specific cell–wall proteins that are highly immunogenic in HIVTB+ and HIV+TB+ patients have been mapped. Antibodies to these regions are absent in subjects with latent TB, BCG vaccination, other pulmonary diseases. To examine the feasibility of devising a peptide based rapid POC test, selected peptides were conjugated to a carrier p...

background: this study aimed to survey a total five common human and veterinary antibiotics, including ampicillin, oxytetracycline, enrofloxacin, tylosin, and ciprofloxacin based on spe-lc-ms-ms technology in a wastewater treatment plant at central plateau of iran. also two sampling techniques, passive and grab samplings were compared in the detection of selected antibiotics. methods: in februa...

The objective of this study was to evaluate the analytical performance of the Abbott ARCHITECT Tacrolimus immunoassay. Proficiency panels and specimens from a population of organ transplant recipients were analyzed in 6 clinical laboratories in Europe and the United States, and the results were compared with other methods. The ARCHITECT assay requires a whole blood specimen pretreatment step wi...

The COVID-19 pandemic has impacted lifestyles, including sexual behaviors. With the lack of data on men who have sex with other (MSM) and their usage sexually explicit media (SEM), this research focused examining if COVID had a similar impact in area as it did general population. researcher administered survey to small number (N = 45) participants recruited from an MSM-focused Reddit group. res...

Introduction The prostanoids are a family of biologically active lipids derived from the 20-carbon essential fatty acids (LCPUFA) which are involved in all aspects of the immune response including the resolution of inflammation. ω3-fatty acids, EPA DPA and DHA are anti-inflammatory, whilst the ω6fatty acid, Arachidonic acid (AA) and its metabolites: 13 (S)-HETE, TXB2, PGF2a and 6-k-PGF1a are pr...

InGaAs-based Metal Semiconductor Metal (MSM) Photodetectors were fabricated and tested as photodetectors and Opto-electronic mixers. A comparison of various processing schemes for MSM InAlAs/InGaAs photodetectors on InP substrates was conducted to minimize the dark current. InAlAs Schottky Enhanced Layers (SEL) was employed on the InGaAs-based MSMs to enhance the barrier height to reduce the da...
