The rRNA gene (rDNA) loci of all arthropod lineages contain non-LTR retrotransposable elements that have evolved to specifically insert into the 28S rRNA genes. Extensive in vitro experiments have been conducted to investigate the mechanism of R2 retrotransposition but little is known of the insertion frequency or cellular factors that might regulate R2 activity. In this article, isofemale line...

We prove that if Ω ⊆ R2 is bounded and R2 \Ω satisfies suitable structural assumptions (for example it has a countable number of connected components), then W 1,2(Ω) is dense in W 1,p(Ω) for every 1 ≤ p < 2. The main application of this density result is the study of stability under boundary variations for nonlinear Neumann problems of the form ( −divA(x,∇u) +B(x, u) = 0 in Ω, A(x,∇u) · ν = 0 o...

AIM Trust is an essential element in physician-patient interaction fostering in general adherence and improving patient- and physician-reported outcomes. Regarding severely injured patients, trust-building behaviour is important because of the severity of injuries and therefore potential associated physical and psychological consequences. The objective of this study was to identify significant ...

OBJECTIVES To determine the sensitivity and specificity of a nephelometric beta-trace protein assay for the diagnosis of liquorrhoea. METHODS One hundred and forty clinical samples with suspected liquorrhoea were analysed by a newly developed nephelometric assay. An established electroimmunoassay served as a reference method. The sensitivity and specificity of the beta-trace nephelometric ass...

This study investigates the role of 3.0T R2* imaging for measuring cardiac iron overload. Experiments were conducted on calibrated phantoms and sickle cell disease (SCD) patients. R2* imaging at 3.0T enabled assessment of wide range of iron concentrations. R2* values at 3.0T were about double of those at 1.5T. Myocardial R2* showed weak and strong correlations with hepatic R2* and serum ferriti...

Proposition 1.1. Let f : R1 → R2 be a homomorphism of rings. If J is an ideal of R2, then f (J) is an ideal of R1 containing ker(f) and furthermore f(f(J)) ⊆ J . Now let f : R1 → R2 be an epimorphism of rings. If J is an ideal of R2 then f(f (J)) = J . If I is an ideal of R1 then f(I) is an ideal of R2. Furthermore we have I ⊆ f (f(I)) = I + ker(f) and thus I = f(f(I)) if I contains ker(f). Thu...

R(2) effect-size measures are presented to assess variance accounted for in mediation models. The measures offer a means to evaluate both component paths and the overall mediated effect in mediation models. Statistical simulation results indicate acceptable bias across varying parameter and sample-size combinations. The measures are applied to a real-world example using data from a team-based h...

In this paper we study the last round of the discrete Voronoi game in R, a problem which is also of independent interest in competitive facility location. The game consists of two players P1 and P2, and a finite set U of users in the plane. The players have already placed two disjoint sets of facilities F and S, respectively in the plane. The game begins with P1 placing a new facility followed ...

i=1 H(ri); (5) HΨ(r1, r2, · · · ) = EΨ(r1, r2, · · · ). (6) (Note: For simplicity, unless necessary, we often write r as r.) Since there is no interaction between particles, the Schrodinger equation is separable. Assume Ψ(r1, r2, · · · , rN ) = φ(r1)φ(r2) · · ·φ(rN ), (7) then Hφαi(ri) = εαiφαi(ri), i = 1, 2, · · ·N. (8) Manybody eigenstate is a product of 1-particle states, Ψα1,α2,···(r1, r2, ...
