Center of mass (CoM) trajectory is important during standing and walking since it can be used as an index for stability and fall prediction. Unfortunately current methods for CoM estimation require the use of specialized equipment (such as motion capture and force platforms) in controlled environments. This paper aims at applying the statically equivalent(More)
— An increasingly aging society creates the need for a reliable evaluation of postural stability, specially for rehabilitation. Estimation of a subject's center of mass (CoM) is important for the assessment of unsupported, stable standing. A portable, in-home estimation of CoM can be used as a rehabilitation tool and could be achieved using a Microsoft's(More)
Brain-machine interfaces (BMI) rely on the accurate classification of event-related potentials (ERPs) and their performance greatly depends on the appropriate selection of classifier parameters and features from dense-array electroencephalography (EEG) signals. Moreover, in order to achieve a portable and more compact BMI for practical applications, it is(More)
BACKGROUND Despite advances in the surgical treatment of patients with severe internal carotid stenosis (ICA), there are selective groups of patients who, due to several reasons, are not good candidates for surgery. Patients with contralateral occlusion are one of these subgroups. Thereby, other therapeutic alternatives, such as angioplasty may be of value.(More)
BACKGROUND AND PURPOSE Bone marrow mononuclear cell (BM-MNC) intra-arterial transplantation improves recovery in experimental models of ischemic stroke. We aimed to assess the safety, feasibility, and biological effects of autologous BM-MNC transplantation in patients with stroke. METHODS A single-blind (outcomes assessor) controlled Phase I/II trial was(More)
Bone marrow mononuclear cell (BM-MNC) intra-arterial transplantation improves recovery in experimental models of ischemic stroke through secretion of cytokines and growth factors (GFs), enhancing neoangiogenesis, and enhancing neuroplasticity. In this study, we tested whether BM-MNC transplantation in stroke patients induces changes in serum levels of(More)
Angioplasty and stenting of the atheromatous internal carotid artery (ICA), besides in patients with a high surgical risk, may be indicated in specific cases such as contralateral occlusion, acute stroke clinical signs, or atherosclerotic pseudo-occlusion (APO). APO of the ICA is an underrecognized condition due to diagnostic difficulties both with(More)
BACKGROUND AND PURPOSE The natural history of the carotid NO is poorly characterized, and the management of patients remains controversial. We report the results and complications associated with CAS and follow-up. MATERIALS AND METHODS Between March 2000 and March 2009, 116 of 836 CAS procedures were performed in patients with carotid NO (13.9%). A total(More)
Despite recent significant advances, pedestrian detection continues to be an extremely challenging problem in real scenarios. In order to develop a detector that successfully operates under these conditions, it becomes critical to leverage upon multiple cues, multiple imaging modalities and a strong multi-view classifier that accounts for different(More)
Cyanobacteria blooms are an increasing problem in temperate freshwater lakes, leading to reduced water quality and in some cases harmful effects from toxic cyanobacteria species. To better understand the role of zooplankton in modulating cyanobacteria blooms, from 2008 to 2010 we measured water quality and plankton abundance, and measured feeding rates and(More)
