This paper introduces a special setting of weakly supervised structured output learning, where the training data is a set of structured instances and supervision involves candidate labels for some local parts of the structure. We show that the learning problem with this weak supervision setting can be efficiently handled and then propose a large margin formulation. To solve the non-convex optim...

The uncoupler, carbonyl cyanide m-chlorophenyl hydrazone (CCCP) is shown to reduce the hydraulic conductivity of barley, maize, mung bean, and onion roots. In barley and maize, the reduction in exudation from excised roots is partly due to the reduction in the permeability of the root to water (I(p)), but it can be inferred that the rate of salt release to the xylem, is also inhibited. The acti...

The cosmological utility of type Ia Supernovae prompted numerous studies of these events, and they are now well characterized observationally, both as individual objects and as a population. In contrast, all other types of supernovae (i.e. core-collapse events) are not as well observationally characterized. While some individual events have been studied in great detail (e.g. SN 1987A or SN 1998...

Linear discriminant analysis (LDA) is commonly used for dimensionality reduction. In real-world applications where labeled data are scarce, LDA does not work very well. However, unlabeled data are often available in large quantities. We propose a novel semi-supervised discriminant analysis algorithm called SSDACCCP . We utilize unlabeled data to maximize an optimality criterion of LDA and use t...

Background: Appearance of multi-drug resistance (MDR) Acinetobacter baumannii imposes limitation on antibiotic therapy in patients. Detection of MDR A. baumannii can play a crucial role to prevent MDR strains spreading in hospitals. The aim of this study was determination the efflux pumps gene expression in tigecyclin resistance strains in collected isolates from selected training hospitals in ...

Clustering addresses the problem of assigning similar objects to groups. Since size clusters is often constrained in practical clustering applications, various capacitated problems have received increasing attention. We consider here p-median (CPMP) which p are selected as cluster centers (medians) such that total distance from these medians their assigned minimized. Each object associated with...

Amaç: Dirençli bakteriyel enfeksiyonların tedavisi için yeni antimikrobiyal bileşiklerin sentezlenmesi çalışmalarının yanısıra, inhibitör moleküllerin antibiyotiklerle kombine kullanılmasına yönelik araştırmalar da yapılmaktadır. Çalışmamızda, fenilalanin-arjininbeta-naftilamid (PAβN), karbonil-siyanid m-klorofenilhidrazon (CCCP) ve 1-(1naphthylmethyl)-piperazine (NMP)’nin Acinetobacter baumann...

conclusions high-level antibiotic resistance can occur as a result of multidrug efflux pumps combined with other mechanisms of resistance. however, the association between over-expression of these genes and highly resistant clinical isolates cannot be ignored. results our results confirmed 203 and 60 p. aeruginosa isolates from burn and non-burn specimens, respectively. the most antibiotic resi...

Sulfate transport by tobacco cells (Nicotiana tabacum L. var. Xanthi) cultured in liquid medium was investigated.Transport was linear with time, had a sharp pH optimum between 6.5 and 7.5, and obeyed Michaelis-Menten kinetics. The Km varied within the range 2 x 10(-5)m and 4 x 10(-5)m and the maximum velocity was in the range 100 to 400 nanomoles per gram fresh weight.hour.Transport was inhibit...

The hypothesis that the buffering of Ca(2+) by mitochondria could affect the Ca(2+)-dependent inhibition of voltage-activated Ca(2+) channels, (I(Ca)), was tested in voltage-clamped bovine adrenal chromaffin cells. The protonophore carbonyl cyanide m-chlorophenyl-hydrazone (CCCP), the blocker of the Ca(2+) uniporter ruthenium red (RR), and a combination of oligomycin plus rotenone were used to ...
