A new logistic regression algorithm based on evolutionary product-unit (PU) neural networks is used in this paper to determine the assets that influence the decision of poor households with respect to the cultivation of non-traditional crops (NTC) in the Guatemalan Highlands. In order to evaluate high-order covariate interactions, PUs were considered to be independent variables in product-unit ...

A study was conducted to evaluate biomarkers of biological effect and physiological assessments related to cardiovascular disease (CVD) among adult male cigarette smokers (SMK), moist snuff consumers (MSC) and non-consumers of tobacco (NTC). Additionally, biomarkers of tobacco and tobacco smoke exposure (BoE) were measured in spot urines and are reported here. Except for the BoE to nicotine and...

The spliceosome is a complex machine composed of small nuclear ribonucleoproteins (snRNPs) and accessory proteins that excises introns from pre-mRNAs. After assembly the spliceosome is activated for catalysis by rearrangement of subunits to form an active site. How this rearrangement is coordinated is not well-understood. During activation, U4 must be released to allow U6 conformational change,...

The hypothesis about the expediency of using RBF-networks to improve accuracy constructing calibration characteristics NTC-thermistors in operating temperature range without dividing it into subranges is confirmed. It has been established that error neural network approximation based on at least one and a half times less than permissible third-order polynomial model, which used software modern ...

GENERATED NOISE IN IGNITION SYSTEMS High-frequency electromagnetic interference (EMI), commonly referred to as Radio Frequency Interference (RFI), generated by a gasoline engine ignition system, comes primarily from the high-voltage side of the circuit. Ignition systems produce sparks at the coil where the battery voltage is converted into high voltage pulses, at the distributor where the high ...

D id you ever notice how complicated your life is becoming? Back in the good o ld days, resistors with a 20% tolerance rating were basic in all electronic circuitry. Through the years w e have "progressed" through the 20% to 10% to 5% to 1 % tolerance resistors. Granted there are many circuits where the 20% resistors are still used quite extensively, but as we strive for higher precision, lower...

In this study, we developed an odor sensor system using chemosensitive resistors, which outputted multichannel data. Mixtures of gas chromatography stationary materials (GC materials) and carbon black were used as the resistors. The interaction between resistors species shifted electrical resistance Sixteen different fabricated on chip. addition, a compact measurement instrument was fabricated....

Embedding resistors into the laminate substrate of printed circuit boards (PCB) leads to a packaging miniaturization and a reduction of production costs. Additionally, it reduces the parasitics associated with surface mounted devices (SMD), due to shorter distances between active and passive components. Therefore, an improvement of the performance at higher frequencies can be achieved in terms ...
