[1] One of the primary goals for the Visible Infrared Imaging Radiometer Suite (VIIRS) on board the Suomi National Polar-orbiting Partnership is to provide the science and user communities with the data continuity of the Environmental Data Records (EDR) (or Level-2 products) over global oceanic waters for various research and applications, including assessment of climatic and environmental vari...

We conclude this series with a description of a dc-60 MHz transceiver that will allow open-software experimentation with software defined radios. I t has been a pleasure to receive feedback from so many QEX readers that they have been inspired to experiment with software-defined radios (SDRs) through this article series. SDRs truly offer opportunities to reinvigorate experimentation in the serv...

Ever evolving wireless communication standards, reduced time-to-market and a need for flexibility and interoperability of multiple wireless communication technologies on a single device are the driving factors behind implementation of wireless standards on Software Defined Radios (SDR) platforms. The concept behind SDR is to implement as much functionality on software as possible. SDR provide g...

In order to clarify the role of GH on ovarian function, recombinant human GH (rhGH) was administered to adult spontaneous dwarf rats (SDR) for 14 days. The SDR were sacrificed on the day of estrus and the effects of rhGH on ovarian weight, follicular population and the viability estimated by 5bromodeoxyuridine (BrdU) incorporation, were studied. RhGH administration caused a significant gain in ...

Software-defined radio (SDR) describes radio transceivers implemented in software that executes on general-purpose hardware. SDR combined with cloud computing technology will reshape the wireless access infrastructure, enabling computing resource sharing and centralized digital-signal processing (DSP). SDR clouds have different constraints than general-purpose grids or clouds: real-time respons...

Phagocytes of the innate immune system, such as monocytes/macrophages, represent a first line of defense against invading microorganisms. Psychological stress is often thought to suppress the functioning of these cells, in part due to the immunosuppressive activity of stress-induced glucocorticoid hormones. However, exposure to the stressor social disruption (SDR) has been shown to increase cyt...

Information retrieval (IR) is a well-established research and development area. Document formats such as SGML (Standard Generalised Markup Language) and XML (eXtensible Mark-up Language) have become widely used in recent years. Traditional IR systems demonstrate limitations when dealing with such documents, which motivated the emergence of structured document retrieval (SDR) technology intendin...

Exposing mice to a social stressor called social disruption (SDR) that involves repeated social defeat during intermale aggression results in increased circulating cytokines, such as interleukin-1α (IL-1α) and IL-1β, and increased reactivity of splenic CD11b(+) macrophages to inflammatory stimuli. For example, upon lipopolysaccharide stimulation, macrophages from stressor-exposed mice produce h...

Short-chain dehydrogenases/reductases (SDR) constitute one of the largest enzyme superfamilies with presently over 46,000 members. In phylogenetic comparisons, members of this superfamily show early divergence where the majority have only low pairwise sequence identity, although sharing common structural properties. The SDR enzymes are present in virtually all genomes investigated, and in human...

In high-dimensional data analysis, sufficient dimension reduction (SDR) methods are effective in reducing the predictor dimension, while retaining full regression information and imposing no parametric models. However, it is common in high-dimensional data that a subset of predictors may have missing observations. Existing SDR methods resort to the complete-case analysis by removing all the sub...
