27 The aim of this study was to determine how muscle activity and body orientation contribute to 28 the triceps surae spinal transmission modulation, when moving from a sitting to a standing 29 position. Maximal H-reflex (Hmax) and motor potential (Mmax) were evoked in the soleus 30 (SOL), medial and lateral gastrocnemius in 10 male subjects and in three conditions: passive 31 sitting, upright ...

Image classification is one of the most important topics in computer vision. It became crucial for large image datasets. In literature, several approaches are proposed. this context, Bag-of-Visual Words (BoVW) model has been widely used. The BoVW relies on building visual vocabulary and images represented as histograms words. However, recently, attention shifted to use complex architectures whi...

BACKGROUND AND AIMS The interspecific allometry of maximum plant height (Hmax) with respect to maximum basal stem diameter (Dmax) has been studied for leptocaulis dicot and conifer tree species. In contrast, virtually nothing is known about the interspecific allometry of pachycaulis species. Here, the interspecific allometries for palms, cacti and cycads are reported and compared with those of ...

The purpose of the study was to analyze the relationships between sprint swimming performance, dry-land power, and kinematics in master swimmers. Twenty-two male master swimmers were separated in two groups based on their chronological age: (i) 30-39 years and; (ii) 40-49 years. Maximum dry-land power was determined through counter movement jump and 3 kg medicine ball throwing (Hmax and Tmax, r...

In the present work, we use dune modeling in order to investigate the evolution of transverse dunes in the presence of vegetation. The vegetation is allowed to grow up to a maximum height Hmax with a growth rate R that oscillates in time. We find that the presence of the vegetation establishes a maximum height for the transverse dunes. If the transverse dune is larger than this maximum size, th...

Knee joint effusion causes quadriceps inhibition and is accompanied by increased soleus muscle excitability. In order to reverse the neurological alterations that occur to the musculature following effusion, we need to understand the extent of neural involvement. Ten healthy adults were tested on two occasions; during one session, subjects had their knees injected with saline and in the other a...

In this paper we consider an object categorization system using local HMAX features. Two feature matching techniques are compared: the MAX technique, originally proposed in the HMAX framework, and the histogram technique originating from Bag-of-Words literature. We have found that each of these techniques have their own field of operation. The histogram technique clearly outperforms the MAX tec...
