In the last few lectures, we talked about various kinds of online learning problems. We started with the simplest case in which there is a perfect expert, who is always right. In the last lecture, we generalize this into the case in which we might not have a “perfect expert”, but instead we have a panel or subcommittee of experts, whose combined prediction is always right. We also introduced th...

BACKGROUND A COS represents an agreed minimum set of outcomes that should be measured and reported in all trials of a specific condition. The COMET (Core Outcome Measures in Effectiveness Trials) initiative aims to collate and stimulate the development and application of COS, by including data on relevant studies within a publically available internet-based resource. In recent years, there has ...

We investigate the effect of the Rashba interaction on two dimensional superconductivity. The presence of the Rashba interaction lifts the spin degeneracy and gives rise to the spectrum of two bands. There are intraband and interband pairs scattering which result in the coupled gap equations. We find that there are isotropic and anisotropic components in the gap function. The latter has the for...

Background A systematic review of core outcome sets (COS) identified 198 COS [1]. A range of methods were used to develop COS. Furthermore, 164/178 studies that described the methods used did not provide an explanation regarding their choice of methodology. There is little guidance about how to conduct or report COS studies and it is currently uncertain which of these methods are the most suita...

abstract leafy vegetables such as lettuce are more susceptible to post harvest losses, thus application desirable treatments can be recommendable. generally, type of packaging, such as modified atmosphere packaging (map) and wrapping can considerably suppress post harvest loss of horticultural products. in this study, the effects of polypropylene film (thickness 30 and 40 micron) wrapping and m...

BACKGROUND Catheter-related infections (CRIs) caused by peripheral intravenous catheters (PIVCs) are an increasingly common iatrogenic complication. To prevent this, recommended timelines for routine replacement of PIVCs have increased from 48 h to 72 h and subsequently to 96 h, despite a lack of supporting scientific evidence. AIM To compare closed-system (COS) PIVCs with open-system (MOS) P...

Recently, we have shown that there do not exist warped product semi-slant submanifolds of cosymplectic manifolds [K.A. Khan, V.A. Khan and Siraj Uddin, Balkan J. Geom. Appl. 13 (2008), 55–65]. The nearly cosymplectic structure generalizes the cosymplectic one. Therefore the nearly Kaehler structure generalizes the Kaehler structure in almost Hermitian setting. It is interesting that the warped ...

We investigated the protective effects and mechanisms of chitosan oligosaccharides (COS) on experimental autoimmune anterior uveitis (EAAU) in rats. EAAU was induced in Lewis rats by footpad and intraperitoneal injections of melanin-associated antigen. The rats received intraperitoneal injections of low-dose (5 mg/kg) or high-dose (10 mg/kg) COS or PBS daily after the immunization. The effects ...

PURPOSE After a century, cheiro-oral syndrome (COS) was harangued and emphasized for its localizing value and benign course in recent two decades. However, an expanding body of case series challenged when COS may arise from an involvement of ascending sensory pathways between cortex and pons and terminate into poor outcome occasionally. MATERIALS AND METHODS To analyze the location, underlyin...
