We propose a new biological framework, spatial networks of hybrid input/output automata (SNHIOA), for the efficient modeling and simulation of excitable-cell tissue. Within this framework, we view an excitable tissue as a network of interacting cells disposed according to a 2D spatial lattice, with the electrical behavior of a single cell modeled as a hybrid input/ouput automaton. To capture th...

This work presents information on the patterns of yield determination by yield components as a function of the level of management of the crop. The data used for the analyses were obtained from 8 field experiments located across Poland in 2009 and 2010. 25 winter wheat cultivars were evaluated at two management levels, i.e., at a low input of nitrogen fertilisation and pesticides and at a h...

this paper proposes a low voltage (±0.55v supply voltage) low power (44.65µw) high common mode rejection ratio (cmrr) differential amplifier (d.a.) with rail to rail input common mode range (icmr), constant transconductance (gm) and enhanced frequency performance. its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

this study was designed to find which one of the three different presentations, i.e. input, input-output, and output-input, will be more effective in iranian efl learners' vocabulary acquisitions. to this end, first 54 out of 64 female students, aged from 19 to 23 years, with an average of 21, were selected out of starter-level efl learners at the university of tarbiat moalem in bandar abb...

The present study was undertaken to investigate the effects of varying frequency patterns (FPs) of words on the productive acquisition of a young EFL learner in a home setting. Target words were presented to the learner using games and role plays. They were subsequently traced for their frequencies in input and output. Eighteen immediate tests and delayed tests were administered to measure the ...
