Two-electron reductive carbonylation of the uranium(VI) nitride [U(Tren(TIPS))(N)] (2, Tren(TIPS)=N(CH2CH2NSiiPr3)3) with CO gave the uranium(IV) cyanate [U(Tren(TIPS))(NCO)] (3). KC8 reduction of 3 resulted in cyanate dissociation to give [U(Tren(TIPS))] (4) and KNCO, or cyanate retention in [U(Tren(TIPS))(NCO)][K(B15C5)2] (5, B15C5=benzo-15-crown-5 ether) with B15C5. Complexes 5 and 4 and KNC...

The RADARs use complex techniques such as stagger PRI, jitter PRI with frequency agile characteristics. The frequency agile RADARs switch frequencies with in a pulse to get different types of advantages. Today lot of RADAR signal processing takes place on FPGA platform. These signal processing algorithms include pulse parameters estimation, deinterleaving of mixed pulse patterns, processing com...

During meiosis programmed DNA double-strand breaks (DSBs) are repaired by homologous recombination using the sister chromatid or the homologous chromosome (homolog) as a template. This repair results in crossover (CO) and non-crossover (NCO) recombinants. Only CO formation between homologs provides the physical linkages guiding correct chromosome segregation, which are essential to produce heal...

In addition to the ATP-binding cassette (ABC)-type nitrate/nitrite-bispecific transporter, which has a high affinity for both substrates (K(m), approximately 1 microM), Synechococcus elongatus has an active nitrite transport system with an apparent K(m) (NO(2)(-)) value of 20 microM. We found that this activity depends on the cynABD genes, which encode a putative cyanate (NCO(-)) ABC-type trans...

Modeling large military targets is a challenge as they can be complex systems encompassing myriad combinations of human, technological, and social elements that interact, leading to complex behaviors. Moreover, such targets have multiple components and structures, extending across multiple spatial and temporal scales, and are in a state of change, either in response to events in the environment...

We show that, during budding yeast meiosis, axis ensemble Hop1/Red1 and synaptonemal complex (SC) component Zip1 tend to occur in alternating strongly staining domains. The widely conserved AAA+-ATPase Pch2 mediates this pattern, likely by means of direct intervention along axes. Pch2 also coordinately promotes timely progression of cross-over (CO) and noncross-over (NCO) recombination. Opposit...

Glaucoma is one of the most common causes of blindness worldwide. Early detection of glaucoma is traditionally based on assessment of the cup-to-disc (C/D) ratio, an important indicator of structural changes to the optic nerve head. Here, we present an automated optic disc segmentation algorithm in 3-D spectral domain optical coherence tomography (SD-OCT) volumes to quantify this ratio. The pro...

Gas-phase olefin polymerization fluidized-bed reactors are complex processes that are characterized by large time constants and slow transitions. Optimal grade changes can be computed off-line on the basis of a detailed process model and applied to the process in an open-loop mode. However, the presence of uncertainties in the form of process-model mismatch and disturbances make this approach c...
