This paper presents an approach for increasing the reactivity of a humanoid robot’s gait, incorporating Slow Feature Analysis (SFA), an unsupervised learning algorithm issuing from the domain of theoretical biology. The main objective of this work is to find a means to detect disturbances in the gait pattern at an early stage without losing stability. Another goal is to investigate the general ...

Subintimal angioplasty is an effective method for the treatment of long superficial femoral artery (SFA) occlusions. One of the major limiting factors for the success of this procedure is the failure to re-enter the true lumen. The recently introduced luminal re-entry devices provide a high technical success rate, but failures can occur. In such cases, a retrograde popliteal approach can serve ...

The most common anatomical variation of the superficial femoral artery (SFA) is hypoplasia or aplasia associated with a persistent sciatic artery. We report a case exhibiting SFA hypoplasia combined with connection of the deep femoral artery (DFA) to the popliteal artery (in other words, the DFA became the popliteal artery). A 41-year-old man was admitted with a crush injury of the left foot. C...

A 77-year-old man with a history of hemodialysis was referred due to swelling of the right groin. Enhanced computed tomography (CT) showed extravasation of the medium from the superficial femoral artery (SFA) with surrounding large hematoma. Three-dimensional CT angiography revealed rupture of SFA just distal to common femoral artery with pseudoaneurysmal formation. At an emergent surgery, SFA ...

Abstract We introduce methods to apply stochastic frontier analysis (SFA) financial assets as an alternative data envelopment analysis, because SFA allows us fit a with noisy data. In contrast conventional SFA, we wish deal estimation risk, heteroscedasticity in noise and inefficiency terms. investigate measurement error the risk return measures using simulation–extrapolation method develop res...

INTRODUCTION The pharmaceutical industry in the United States spends about $15 billion per year advertising its products to the medical profession [1]. Pharmaceutical detailing, which is using sales representatives to call on physicians to promote products, accounts for about 45 percent of this spending [2]. In order to help sales representatives track sales leads, sales, service requests, and ...

After an episode of myocardial ischemia, opening of the mitochondrial permeability transition pore (mPTP), at the onset of reperfusion, is a critical determinant of myocyte death. We investigated the role of the mPTP as a target for cardioprotection in the human heart. We subjected human atrial tissue, harvested from patients undergoing cardiac surgery, to a period of lethal hypoxia and investi...

automation and the adoption of technological innovations by salespeople: Theory and implications" (1997). Marketing Department Faculty Publications. Paper 28. Introduction This paper is concerned with the adoption of salesforce automation (SFA) systems by organizations and their salesforces. SFA systems consist of centralized database systems that can be accessed through a modem by remote lapto...

We discuss a correlation between star formation activity (SFA) and luminosity of star-forming galaxies at intermediate redshifts of 0.2 ≤ z ≤ 0.6 in both cluster and field environments. Equivalent width (EW) of [Oii] is used for measurement of the SFA, and R-band absolute magnitude, MR, for the luminosity. In lessluminous (MR > ∼ − 20.7) galaxies, we find : (1) the mean EW([Oii]) of cluster gal...

This work addresses the matching of a 3D deformable face model to 2D images through a 2.5D Active Appearance Models (AAM). We propose a 2.5D AAM that combines a 3D metric Point Distribution Model (PDM) and a 2D appearance model whose control points are defined by a full perspective projection of the PDM. The advantage is that, assuming a calibrated camera, 3D metric shapes can be retrieved from...
