BACKGROUND/AIMS Reconstruction of large full thickness upper lid defects that cannot be closed directly often rely on utilising the lower lid. An example is the Cutler Beard procedure. A one stage technique for repair of large horizontal upper lid defects utilising local posterior and anterior lamella advancement flaps is described and the results reported. METHOD Eight cases with upper lid d...

Pseudomonas aeruginosa lipase is a 29-kDa protein that, following the determination of its crystal structure, was postulated to have a lid that stretched between residues 125 and 148. In this paper, using molecular dynamics simulations, we propose that there exists, in addition to the above-mentioned lid, a novel second lid in this lipase. We further show that the second lid, covering residues ...

The Green’s function, defined as the response recorded at the acquisition surface for a source located in the interior of the subsurface, is a combination of the downgoing and upgoing wave fields needed to reconstruct an image of the discontinuities inside the earth. Two-sided Green’s function representations require measurement on the full boundary enclosing the domain of interest and allow us...

We demonstrate how to use Lautemann's proof that BPP is in p 2 to exhibit that BPP is in RP PromiseRP. Immediate consequences show that if PromiseRP is easy or if there exist quick hitting set generators then P = BPP. Our proof vastly simpliies the proofs of the later result due to Andreev, Clementi and Rolim and Andreev, Clementi, Rolim and Trevisan. Clementi, Rolim and Trevisan question wheth...

Language Identification (LID) of speech can be split into two processes; phone recognition and language modelling. This two stage approach underlies some of the most successful LID systems. As phone recognizers become more accurate it is useful to simulate a very accurate phone recognizer to determine the effect on the overall LID accuracy. This can be done by using phone transcripts. In this p...

this paper addresses the problem of testing simple hypotheses about the mean of a bivariate normal distribution with identity covariance matrix against restricted alternatives. the lrts and their power functions for such types of hypotheses are derived. furthermore, through some elementary calculus, it is shown that the power function of the lrt satisfies certain monotonicity and symmetry prope...

We are given a bipartite graph G = (A ∪ B,E) where each vertex has a preference list ranking its neighbors: in particular, every a ∈ A ranks its neighbors in a strict order of preference, whereas the preference lists of b ∈ B may contain ties. A matching M is popular if there is no matching M ′ such that the number of vertices that prefer M ′ to M exceeds the number that prefer M to M ′. We sho...
