This study evaluated the efficacy of a combination tablet formulation of buprenorphine containing 8 mg of buprenorphine and 2 mg of naloxone for every other day treatment and whether increasing the daily maintenance dose was essential for maintaining an efficacious alternate-day treatment. Twenty-six opioid-dependent outpatients completing a 16-day baseline entered a double-blind, placebo-contr...

Using Monte Carlo simulations of a touching-bead model of double-stranded DNA, we show that DNA extension is enhanced in isosceles triangular nanochannels (relative to a circular nanochannel of the same effective size) due to entropic depletion in the channel corners. The extent of the enhanced extension depends non-monotonically on both the accessible area of the nanochannel and the apex angle...

We propose the set of coupled ordinary differential equations dnj/dt = n 2 j−1 − n 2 j as a discrete analog of the classic Burgers equation. We focus on traveling waves and triangular waves, and find that these special solutions of the discrete system capture major features of their continuous counterpart. In particular, the propagation velocity of a traveling wave and the shape of a triangular...

We prove that, for any n, the monoid of all $$n \times n$$ supertropical matrices extending tropical satisfies nontrivial semigroup identities; in particular, such triangular admit exactly same identities satisfied by matrices. These are carried over to labeled-weighted digraphs with double arcs.

This paper describes a new structure of a six-DOF parallel robot. First, a known planar three-DOF double-triangular structure is modified by replacing the stationary triangle with a circle. It increases the work envelope considerably especially when rotational motions are required. The ability for unlimited rotational motion allows extending the structure into six-DOF by using two sets of stati...

Cutaneous fungal infections occurred in four captive brown tree snakes (Boiga irregularis). The ventral scales were most commonly affected, and lesions began as areas of erythema and edema with vesicle formation, followed by development of caseous brown plaques. Lesions usually started where ventral scales overlapped and spread rapidly. All snakes died within 14 days after clinical signs were f...
