In 1948, Hodgkin distinguished between three classes of excitability on the basis of spiking patterns observed in crustacean axons. This classification scheme is still applied today because it captures fundamental differences in excitability that stem from how action potentials, or spikes, are generated. The nonlinear dynamical mechanism responsible for spike initiation in each cell class has b...

Some classical ordering problems (sorting, finding the maximum, finding the maximum and the minimum, finding the largest and the next largest, merging, and finding the median) are considered from a recursive viewpoint. If X(n) denotes an instance of size n of any one of these problems then X(n) can be solved by finding the solution to a number ~(n, k) of problems X(k) for some fixed k; ~(n, k) ...

Background: Active educational video games (AVGs) appear to have a positive effect on elementary school students’ motivation leading to enhanced learning outcomes. The purpose of this study was to identify the effectiveness of an AVG on elementary school students’ science knowledge learning, physical activity (PA) level, and interest-based motivation. Methods: In this randomized controlled stud...

AIM The aim of the present investigation was to analyse cephalometric skeletal structures and hormonal and enzymatic parameters in young obese subjects in comparison with those of normal weight subjects. MATERIALS AND METHODS The whole sample consisted of 50 Caucasian patients (28 males and 22 females) whose lateral radiographs, laboratory hormonal and enzymatic analyses were already availabl...
