First-principles calculations were employed to study the mechanical properties for the recently proposed tetragonal B₄CO₄ (t-B₄CO₄). The calculated structural parameters and elastic constants of t-B₄CO₄ are in excellent agreement with the previous results, indicating the reliability of the present calculations. The directional dependences of the Young's modulus and shear modulus for t-B₄CO₄ are...

Recent reports indicate the possible role of bladder CO(2) as a marker of low perfusion states. To test this hypothesis, shock was induced in six beagle dogs with 1 mg/kg of E. coli lipopolysaccharide, gastric CO(2) (CO(2)-G) was measured with a continuous monitor, and a pulmonary catheter was inserted in the bladder to measure CO(2) (CO(2)-B). Levels of CO(2)-B were found to be lower than thos...

Let B be a commutative algebra and A B-algebra (determined by an homomorphism ?:B?A). M. D. Staic introduced Hochschild like cohomology H•((A,B,?);A) called secondary cohomology, to describe the non-trivial deformations of A. J. Laubacher et al later obtained natural construction new chain complex C¯•(A,B,?) in process introducing cyclic (co)homology. In this paper, we establish connection betw...

Bicalutamide is the most widely used non-steroidal antiandrogen for treating early stage prostate cancer, but suffers variable oral absorption due to its limited aqueous solubility. Thus, our objective was to synthesize novel biodegradable copolymers for the systemic micellar delivery of bicalutamide. Flory-Huggins interaction parameter (cFH) was used to assess compatibility between bicalutamid...

In the “mixed hypergraph” model, proper coloring requires that vertex subsets of one type (called C-edges) should contain two vertices of the same color, while the other type (D-edges) should not be monochromatic. Voloshin [Australas. J. Combin. 11 (1995), 25–45] introduced the concept of C-perfectness, which can be viewed as a dual kind of graph perfectness in the classical sense, and proposed...

We present a novel approach to mine word similarity in Textual Case Based Reasoning. We exploit indirect associations of words, in addition to direct ones for estimating their similarity. If word A co-occurs with word B, we say A and B share a first order association between them. If A co-occurs with B in some documents, and B with C in some others, then A and C are said to share a second order...

conclusions the significant number of coinfected hiv-hcv patients only had hbcab positive test without detectable hbv-dna. further studies for detection of hbv-dna in both serum and liver biopsy specimens may help clarify the impact of hbv infection in coinfected hiv/hcv patients. results of 103 hiv-hcv coinfected patients, both hbsag and hbcab were positive in 7 patients (6.8%), negative in 44...

Background: HIV infected persons are also at risk for Infection with other pathogens, like Hepatitis B virus (HBV) and Hepatitis C virus (HCV). One of the main steps in the planning of treatment and prevention is the study of the HIV positive population who have HBV and/or HCV infection. The objective of this study was to determine the prevalence of HIV and Hepatitis B and C dual infection in ...

Given an arbitrary intruder deduction capability, modeled as an inference system S and a protocol, we show how to compute an inference system b S such that the security problem for an unbounded number of sessions is equivalent to the deducibility of some message in b S. Then, assuming that S has some subformula property, we lift such a property to b S, thanks to a proof normalisation theorem. I...
