STUDY DESIGN Retrospective observational study. PURPOSE To examine fractional anisotropy (FA) values and apparent diffusion coefficient (ADC) values of damaged nerves to discriminate between lumbar intraspinal stenosis (IS) and foraminal stenosis (FS) using diffusion tensor imaging (DTI). OVERVIEW OF LITERATURE It is important in the selection of surgical procedure to discriminate between l...

PURPOSE To determine the perioperative factors that are significantly correlated with the final visual acuity following reattachment of a macula-off rhegmatogenous retinal detachment (RRD) by vitrectomy. METHODS Twenty-nine eyes of 29 patients with a successfully reattached RRD by vitrectomy were retrospectively analyzed. Spectral-domain optical coherence tomographic images of the macular reg...

OBJECTIVE Intraosseous access is a rapid and safe alternative when peripheral vascular access is difficult. Our aim was to assess the safety and efficacy of a semi-automatic intraosseous infusion device (EZ-IO) when using a management algorithm for difficult vascular access in an out-of-hospital setting. METHODS This was a one-year prospective, observational study by mobile intensive care uni...

BACKGROUND Usually the training set of online brain-computer interface (BCI) experiment is small. For the small training set, it lacks enough information to deeply train the classifier, resulting in the poor classification performance during online testing. METHODS In this paper, on the basis of Z-LDA, we further calculate the classification probability of Z-LDA and then use it to select the ...

Background: Tannase can be obtained from the various sources for example tannin rich plants; however microbial sources are preferred for industrial production. In microbial sources, the Aspergillus and Penicillium genus and lactic acid bacteria mostly produce tannase. However, it has been identified that this enzyme is produced by many fungi and bacteria, but research...

where (a) because that E and Tr are both linear operators and Tr[E[ZZ ]] is certain positive number which is independent on the optimization variables, then this term can be replaced by another positive constant Tr[EZ[Z ]EZ[Z]]. Based on the equivalence between (13) and (14), we can apply the result shown in [28, Lemma 2]. Since the constraint set is polyhedral in the formulation (3), the linea...

The essential matrix, first introduced by Longuet-Higgins [5], is a 3× 3 matrix encoding the relative pose information between two views. Conventional approaches for relative pose estimation is to solve a system of linear equations. The 5-pt algorithm [6] is the current state-of-the-art algorithm in relative pose estimation. It is a minimal-set direct solver which solves the essential matrix as...
