This paper presents a 10-bit, 600 MS/s direct-sampling sub-Nyquist rate PUMP DAC-based frequency-agile wideband transmitter for IEEE 802.22 cognitive radio applications in the VHF/UHF TV band (54 – 862 MHz).Multi-mode reconstruction using Gilbert cells, including non-return-to-zero, return-to-complement, and return-to-complement with reset,

This paper provides a brief introduction to the R package bio.infer, a Phone Adaptor set of scripts that facilitates the use of maximum likelihood (ML) methods for predicting environmental conditions from assemblage composition.Environmental conditions can often be inferred from only biological data, and these inferences are useful when other sourc

Humans are rather funny things, we often tend to imagine that we Lamp are so ?special?, so divorced by our supposed ?intelligence? from the influences of the ?natural world? and so unique in our ?abstracting? abilities.We have this persistent delusion, evident since ancient Greek times, that we are ?rational?, that we can behave as ?disinterested o

Abstract Background A loot box is a gaming term for an electronic lottery that randomly provides items that enhance the gaming experience.In recent years, loot boxes have been increasingly Photography discussed as a risk factor of gaming disorder (GD).While they may be purchased for a few dollars at a time, the cumulative expenses resulting from th

The article investigates vibration and noise protection Dog-Chews devices for wheeled vehicles using dynamic vibration absorbers (DVA).Algorithms for modeling their dynamic characteristics based on adaptive calculation schemes are presented.A non-linear suspension with DVA and a noise-absorbing partition is considered, which is due to the introduct
