A Mobile Ad hoc Network (MANET) consists of multiple wireless mobile devices that form a network on the fly to allow communication with each other without any infrastructure. Due to its nature, providing security in these networks is challenging. Threshold Cryptography (TC) provides a promise of securing these networks. In this paper, we discuss our RSA-based Threshold Cryptography (RSA-TC) and...

This study examined longitudinal adoption patterns of tobacco cessation (TC) counseling and TC pharmacotherapy in substance use disorder treatment programs and baseline predictors (program characteristics and program culture) of these patterns 12-months later. Telephone survey data were collected in 2010 from 685 randomly sampled program administrators working in geographically representative t...

(cf. Eqn. (3), (4) of Ref. [1]). Phenomenologically, the coupling term can be motivated in the weak coupling limit by the requirement that it should yield a cos(φ1 − φ2) dependence on the phase difference and not change the free energy if two identical superconductors with the same phase are coupled to each other. For small γ and near Tc, it also reproduces the temperature dependence of the cri...

Sporadic supply interruptions of select radiopharmaceuticals on the global market require consideration of alternative agents to support continuity of essential nuclear medicine examinations. During an acute shortage of Xenon-133 and technetium-99 metastable (Tc-99m) diethylene-triamine-pentaacetate (DTPA), our institution used aerosolized Tc-99m hydroxymethylene diphosphonate (HDP), a radiopha...

I briefly review several key issues in understanding the cuprate superconductors from the point of view of doped-Mott-insulator. Then I present an effective low-energy theory and show that the phase diagram of such a model includes an anti-ferromagnetic (AF) phase, a superconducting state, and a pseudogap phase at low doping and low temperature, consistent with the experimental one. The dual to...

a-Tocopherol (a-TC) and a-TC/cyclodextrin (CD)–inclusion complex (IC) incorporated electrospun poly(lactic acid) (PLA) nanofibers (NF) were developed via electrospinning (PLA/a-TC–NF and PLA/a-TC/g-CD–IC–NF). The release of a-TC into 95% ethanol (fatty food simulant) was much greater from PLA/a-TC/g-CD–IC–NF than from PLA/a-TC–NF because of the solubility increase in a-TC; this was confirmed by...

Background—The myocardial uptake of Tc-sestamibi is attenuated by dobutamine stress, resulting in underestimation of ischemia. N-Ethyl-N-ethoxy-dithiocarbamato-N-Tc (Tc-N-NOET) is a new Tc-labeled perfusion agent that is highly extracted by the myocardium by a mechanism different from that defined for Tc-sestamibi. We therefore hypothesized that Tc-N-NOET uptake would not be attenuated by dobut...

There are two conflicting theories of how plasma vitamin B12 (B12) is transported in man: (a) by two distinct transport proteins, transcobalamins I and II (TC I and II), each having a specific role and time of function; and (b) by three active transport proteins, TC I, II, and III, that take up B12 randomly in proportion to the unsaturated amounts of each. To test these theories a man was given...

Little is known about the association between total cholesterol (TC) and all-cause mortality in the elderly (especially the very elderly). Here we examined the association between TC and all-cause mortality in 207 very elderly (85-year-old) participants. In 2003, we performed a baseline laboratory blood examination, and blood pressure (BP) and body mass index (BMI) measurements, and lifestyle q...

We define and develop a homotopy invariant notion for the topological complexity of map f:X?Y, denoted TC(f), that interacts with TC(X) TC(Y) in same way cat(f) cat(X) cat(Y). Furthermore, TC(f) satisfy inequalities as cat(X). compare it to other invariants defined papers [15], [16], [17], [18], [20]. apply studying group homomorphisms f:H?G.
