objective: to compare the awareness of provisions of consumer protection act among dental and medical professionals in udaipur city, rajasthan, india. materials and methods: in a cross sectional study, a total of 448 professionals (253 males, 195 females) belonging to dental (222) and medical (226) categories were surveyed using a self administered structured questionnaire. the questionnaire co...
2-Substituted 3-nitropropanoic acids were designed and synthesized as inhibitors against carboxypeptidase A (CPA). (R)-2-Benzyl- 3-nitropropanoic acid showed a potent inhibition against CPA (K(i)=0.15 microM). X-ray crystallography discloses that the nitro group well mimics the transition state occurred in the hydrolysis catalyzed by CPA, that is, an O,O'-bidentate coordination to the zinc ion ...
We consider the problem of defining and achieving plaintextaware encryption without random oracles in the classical public-key model. We provide definitions for a hierarchy of notions of increasing strength: PA0, PA1 and PA2, chosen so that PA1+IND-CPA → INDCCA1 and PA2+IND-CPA → IND-CCA2. Towards achieving the new notions of plaintext awareness, we show that a scheme due to Damg̊ard [12], denot...
In this paper we present an alignment experiment between patterns of verb use discovered by Corpus Pattern Analysis (CPA; Hanks 2004, 2008, 2013) and verb senses in OntoNotes (ON; Hovy et al. 2006, Weischedel et al. 2011). We present a probabilistic approach for mapping one resource into the other. Firstly we introduce a basic model, based on conditional probabilities, which determines for any ...
Citromicrobium bathyomarinum is a bacteriochlorophyll a-containing aerobic anoxygenic phototrophic bacterium. Here, we report the draft genome sequence of C. bathyomarinum JL354, which was the first C. bathyomarinum strain isolated from a euphotic marine environment. The JL354 genome sequence reveals, for the first time, the coexistence of two different photosynthetic operons in a single strain.
Recently, swarm intelligence algorithms have received much attention because of their flexibility for solving complex problems in the real world. a new algorithm called colony predation (CPA) has been proposed, taking inspiration from predatory habits groups nature. However, CPA suffers poor exploratory ability and cannot always escape solutions known as local optima. Therefore, to improve glob...
We exploit the versatility provided by metal-dielectric composites to demonstrate controllable coherent perfect absorption (CPA) or anti-lasing in a slab of heterogeneous medium. The slab is illuminated by coherent light from both sides, at the same angle of incidence and the conditions required for CPA are investigated as a function of the different system parameters. Our calculations clearly ...
Differentiated HepaRG cells maintain liver-specific functions such as drug-metabolizing enzymes. In this study, the feasibility of HepaRG cells as a human hepatocyte model for in vitro toxicity assessment was examined using selected hepatotoxic compounds. First, basal drug-metabolizing enzyme activities (CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4, uridine 5'-diphospho-glucuronosyltransfera...
The current regimen for treating nerve agent poisoning does not sufficiently suppress the excitotoxic activity that causes severe brain damage, especially in cases where treatment is delayed and nerve agent-induced status epilepticus develops. New therapeutic targets are required to improve survivability and minimize neuropathology after irreversible acetylcholinesterase inactivation. Earlier s...
Whereas encryption schemes withstanding passive chosenplaintext attacks (CPA) can be constructed based on a variety of computational assumptions, only a few assumptions are known to imply the existence of encryption schemes withstanding adaptive chosen-ciphertext attacks (CCA2). Towards addressing this asymmetry, we consider a weakening of the CCA2 model — bounded CCA2-security — wherein securi...
