Recall that one motivation for studying non-uniform computation is the hope that it might be easier to prove lower bounds in that setting. (This is somewhat paradoxical, as non-uniform algorithms are more powerful than uniform algorithms; nevertheless, since circuits are more “combinatorial” in nature than uniform algorithms, there may still be justification for such hope.) The ultimate goal he...

The class P=poly is known to be the class of sets with small descriptions, more speci cally, polynomial size circuits. In this paper, we discuss the problem of obtaining the polynomial size circuits for a given set in P=poly by using the set as an oracle. Recent results on upper and lower bounds of the relative complexity of this problem are presented. We also introduce two related research top...

background: chlorinated pesticides have been used in pest control for several decades in the world. these compounds are still applied in many regions, and their continuous usage has resulted in their bioaccumulation and residue in the food chain. these residues could transfer to food products and accumulate in fat tissues. undoubtedly, the breast milk could be a significant biomarker for estima...

BACKGROUND Persistent organic pollutants (POPs) have been suggested to be linked to obesity. We have previously shown that less-chlorinated PCBs were positively related to fat mass, while highly-chlorinated PCBs were inversely related to obesity. OBJECTIVE The aim of the present evaluation is to investigate the relationship between retrospective assessed life-time change in body weight (20-70...

In this research, the student will explain a candidate construction for indistinguishability obfuscation, based on a recent paper by Garg et al. (FOCS 2013). This is done by first describing the main building blocks, then how these are used to build indistinguishability obfuscation for NC, and expanded to P/poly. Security and alternative constructions are very briefly discussed.

The goal was to evaluate the associations between testicular hormones at adolescence and the exposure to chlorination by-products when attending chlorinated swimming pools. We obtained serum samples from 361 school male adolescents (aged 14-18years) who had visited swimming pools disinfected with chlorine or by copper-silver ionization. We analysed serum concentrations of inhibin B (two differe...

Pseudomonas aeruginosa is a ubiquitous environmental bacterium and an opportunistic pathogen with the ability to rapidly develop multidrug resistance under selective pressure. Previous work demonstrated that upon exposure to the environmental contaminant pentachlorophenol (PCP), P. aeruginosa PAO1 increases expression of multiple multidrug efflux pumps, including the MexAB-OprM pump. The curren...

The discrepancies between polychlorinated dibenzo-p-dioxin to polychlorinated dibenzofuran (PCDD to PCDF) ratios in laboratory and field studies in the exhaust of combustion sources are not fully explained by available formation models. In this paper we present the results of experimental studies of the surface mediated formation of PCDD/F at the conditions mimicking the combustion cool zone fr...
