OBJECTIVE To investigate an appropriate depth of needle insertion during trigger point injection into the rhomboid major muscle. METHODS Sixty-two patients who visited our department with shoulder or upper back pain participated in this study. The distance between the skin and the rhomboid major muscle (SM) and the distance between the skin and rib (SB) were measured using ultrasonography. Th...

PURPOSE To compare two sling designs (single loop or double pentagon) and a variety of suture material that was used in frontalis suspension surgery for correction of upper eyelid ptosis. DESIGN Retrospective, nonrandomized, comparative interventional case series. METHODS Medical record review of 99 patients (164 surgeries) who underwent frontalis suspension surgery for upper eyelid ptosis ...

OBJECTIVE To determine the normal oculopalpebral anthropometric measurements of a Nigerian adult population. SUBJECTS AND METHODS A population-based prospective observational random survey was conducted in Enugu, South-Eastern Nigeria between January and April 2010. The participants were healthy adults comprising 248 males and 252 females aged 18-76 years. One thousand eyes were examined. Dem...

Abstract: Aim Evaluate the structure of aquatic macrophytes assembly Jacarecica II Dam, Areia Branca, Sergipe, and verify if distance from margin is a driver for species richness, composition in this environment. Methods We settled transects where we plotted quadrats subplots. The were perpendicular relation to reservoir margin, first quadrat was placed on with four following ones completely ov...

We propose an online learning algorithm for large margin training of continuous density hidden Markov models. The online algorithm updates the model parameters incrementally after the decoding of each training utterance. For large margin training, the algorithm attempts to separate the log-likelihoods of correct and incorrect transcriptions by an amount proportional to their Hamming distance. W...

In this article we construct a maximal margin classification algorithm for arbitrary metric spaces. At first we show that the Support Vector Machine (SVM) is a maximal margin algorithm for the class of metric spaces where the negative squared distance is conditionally positive definite (CPD). This means that the metric space can be isometrically embedded into a Hilbert space, where one performs...

We consider perceptron-like algorithms with margin in which the standard classification condition is modified to require a specific value of the margin in the augmented space. The new algorithms are shown to converge in a finite number of steps and used to approximately locate the optimal weight vector in the augmented space following a procedure analogous to Bolzano’s bisection method. We demo...

Person re-identification aims to match images of the same person across disjoint camera views, which is a challenging problem in video surveillance. The major challenge of this task lies in how to preserve the similarity of the same person against large variations caused by complex backgrounds, mutual occlusions and different illuminations, while discriminating the different individuals. In thi...

Bifurcation of the carotid artery at a cephalic location greatly increases the risk associated with carotid endarterectomy (CEA). Mandibular subluxation (MS) can improve access to the cephalic location; however, the benefits of MS remain unclear. The present study objectively assessed the efficacy of MS. MS was performed with only wire fixation of healthy teeth in four patients (Group A), with ...
