introduction: previous studies indicate that exercise influences cognitive function. nevertheless, considering that exercise in animal study can be voluntary, or forced, effects of exercise (specially forced exercise) on learning and memory abides as a matter of controversy. the present study aimed to investigate the effects of treadmill exercise on ltp in the dentate gyrus of rats. methods: th...

introduction: over the last decade, exposure to non-ionizing electromagnetic waves due to base station antenna has increased. this in vivo study was planned for evaluating the effects of whole-body exposure to 950 mhz field of gsm mobile phone system on rat dentate gyrus long-term potentiation. materials and methods: 24 naive male wistar rats (3 month old, 225|¡|25 g) were randomly divided in t...

sewage effluent is the carrier of huge amounts of n (0.09 to 0.16%), p (0.023 to 0.029 %), and k (0.11 to 0.18%) and as well as it is rich in organic carbon (3.27%). transfer of the toxic trace metal (pb) from the contaminated site can be seized out from the food chain through application of feso4.7h2o and caso4 in a larger area. the efficacy of the toxic metal immobilization through an applica...

We present a mechanized proof of the metatheory of LF, i.e. the decidability of typechecking and the existence and uniqueness of canonical forms. We use a syntactic approach in which we define a translation from LF to its canonical forms presentation (in which only beta-short, eta-long terms are well-formed) and prove soundness and completeness of the translation, establishing that definitional...

The physiological significance of spectral and fractal components of spontaneous heart rate (HR) variability in the fetus remains unclear. To examine the relationship between circadian rhythms in different measures of HR variability, R-R interval time series obtained by fetal ECGs were recorded continuously over 24 h in five pregnant sheep at 116-125 days gestation. Conventional measures of sho...

An approach for enhancing the operating bandwidth of classic dual-band power divider (PD) is proposed by using metamaterial (MTM) units. To overcome limitation EM simulation and improve design efficiency, we propose an artificial neural network (ANN) that enables inverse prediction MTM-PD geometry from its desired physical response. In ANN approach, convolutional long short-term memory are comb...

Lymphatic filariasis (LF) is a mosquito-borne parasitic infection responsible for long-term chronic morbidity in the form of lymphoedema, genital pathology (especially hydroceles), recurrent disabling fevers (lymphangitis) and elephantiasis in over 40 million people around the world (Ottesen et al, 2008). Currently, over one billion people are exposed to infection in 81 endemic countries in Asi...

It is recently recognized that the ionosphere is very sensitive to seismic effects, and the detection of ionospheric perturbations associated with earthquakes, seems to be very promising for short-term earthquake prediction. We have proposed a possible use of VLF/LF (very low frequency (3-30 kHz) /low frequency (30-300 kHz)) radio sounding of the seismo-ionospheric perturbations. A brief histor...

A neurofuzzy system is proposed for short-term electric load forecasting. The fuzzy rule base of ReNFuzz-LF consists rules with dynamic consequent parts that are small-scale recurrent neural networks one hidden layer, whose neurons have local output feedback. particular representation maintains the learning nature typical static model, since can be considered as subsystems operating at subspace...

The low frequency (LF) spectral analysis or ‘rhythm spectrum’ approach to the quantitative and comparison of speech rhythms is extended beyond syllable word ‘rhetorical rhythms’ in read-aloud narratives, a selection exploratory scenarios, with aim developing unified theory rhythms. Current methodologies field are first discussed, then choice data motivated modulation-theoretic rhythm spectrum s...
