This has simplifies the uSDX circuit a lot, and there are a number of advantages and features (compared to an analog approach): there is no longer a need for an I/Q alignment procedure due to the very accurate 90 degree Hilbert phase shifter; and there are now adjustable IF DSP filters...
“a dominant logic of globalization” which postulates that there is a single cause for globalization or to a “phenomenon with a complex set of causes” which argues that there are various causes for globalization (Beck, 2000). In corollary, research has not been successful in gras...
By observing the subsampling image, x-axis and y-axis displacements are adjusted to eliminate the initial phases of moiré fringe. Image processor can calculate the required displacements in 3-axis directions of PZT. PZT receives the feedback and execute the 3-axis adjustments until accurate ...
Dinoflagellate chromosomes represent a unique evolutionary experiment, as they exist in a permanently condensed, liquid crystalline state; are not packaged by histones; and contain genes organized into tandem gene arrays, with minimal transcriptional reg
Background Maternal and child undernutrition have adverse consequences for pregnancy outcomes and child morbidity and mortality, and they are associated with low educational attainment, economic productivity as an adult, and human wellbeing. ‘Nutrition-sensitive’ agriculture programs could tackle the under...

As the supply of ecosystem services varies with LULC types, both land conversion and management can influence this feedback in terms of both space and quantity [59]. Although the total areas of grassland and unused land (the two largest components of our dataset) have not varied a great deal...
Hydropower plants are one of the most common and widely used renewable energy sources. These plants provide up to 80% of the total renewable energy. Traditional hydropower plants consist of a rather large water reservoir filled by constructing a dam in front of a river or a water way and flo...

A PLL is a closed loop system in which an internal oscillator is controlled to keep the time and phase of an external periodical signal using a feedback loop. The quality of the lock directly affects the performance of the control loop in grid tied applications. As line notching, voltage ...
