A method for pattern classification using genetic algorithms (GAs) has been recently described in Pal, Bandyopadhyay and Murthy (1998), where the class boundaries of a data set are approximated by a fixed number H of hyperplanes. As a consequence of fixing H a priori, the classifier suffered from the limitation of overfitting (or underfitting) the training data with an associated loss of its ge...

Temperate grasslands are considered the most endangered terrestrial ecosystem worldwide; existent areas play a key role in biodiversity conservation. The Aguapey Valuable Grassland Area (VGA), one of well-preserved temperate grassland within Argentina, is currently threatened by anthropogenic expansion exotic tree plantations. Little known about impacts afforestation over landscape structures; ...

Positron annihilation spectroscopy, Fourier transform-infrared absorption and secondary ion mass spectrometry have been used to study the behavior of gallium vacancy-related defects hydrogen in deuterium (D) implanted subsequently annealed β-Ga2O3 single crystals. The data suggest implantation generates a plethora VGa-related species, including VGa1- VGa2-type defects. latter’s contribution pos...

Recently, several medical devices that use wireless communication are under development. In this paper, the small size frequency shift keying (FSK) transmitter and a monofilar antenna for the capsule endoscope, enabling the medical device to transmit VGA-size images of the intestine. To verify the functionality of the proposed wireless communication system, computer simulations and animal exper...

A compact digitally-controlled single-stage variable gain amplifier (VGA) is introduced, which doubles the dB-linear range through the reconfiguration, saves power by 50% while maintaining the same linearity performance compared to those of the previous design. Implemented in 0.18 mm CMOS technology, the 5-bit digitally-controlled VGA achieves dB-linear gain range of 42 dB (221 to 21 dB) with g...

OBJECTIVE We studied the prevalences of video game use (VGU) and addiction (VGA) in gambling disorder (GD) patients and compared them with subjects with non-video game use (non-VGU) in relation to their gambling behavior, psychopathology, and personality characteristics. METHOD A sample of 193 GD patients (121 non-VGU, 43 VGU, and 29 VGA) consecutively admitted to our pathological gambling un...

It is well known that he in‡uence relation orders the voters the same way as the classical Banzhaf and Shapley-Shubik indices do when they are extended to the voting games with abstention (VGA) in the class of complete games. Moreover, all hierarchies for the in‡uence relation are achievable in the class of complete VGA. The aim of this paper is twofold. Firstly, we show that all hierarchies ar...

Electronic skin (e-skin) has significant application prospects in soft robotics, prosthetics, medical monitoring, and wearable equipment. However, it remains a great challenge for e-skin to comprehensively mimic the multifunctional sensing capabilities characteristics of human skin. Herein, vertical graphene arrays (VGA) were directly fabricated on surface natural latex film using facile method...

Background: Vein of Galen aneurysm (VGA) is the most common form of symptomatic cerebrovascular malformation in neonates. It develops in a fetus in the first trimester of pregnancy due to unknown reasons, but it is likely to have a genetic etiology. The prognosis of VGA is usually poor, particularly in newborns with heart failure due to high-flow intracerebral shunt. Surgery and endovascular em...
