Role of Storage Material in NOX Storage and Reduction (NSR) and Three-Way Catalysts (TWC) During Cycling Operation
NOx storage and reduction (NSR) is a cyclic catalytic process that eliminates NOx from lean burn vehicles. There is an active debate about the NOx reduction mechanism, particularly at a high temperature and cycle frequency. Three-way catalysts (TWC) are widely applied in stoichiometric combustion …

The Effects of Sleep Restriction on Biological, Psychological, and Neurocognitive Measures of Health
… then placed in the Naturally Sleep Restricted (NSR) group (n = 11), or the Experimentally Sleep Restricted (ESR) group (n = 9). The ESR group was assessed on Day 1 and Day 7 (i.e., prior to and following sleep restriction). We hypothesized that following sleep restriction, the ESR group would …

Focus on Basque movements
… a new version of the Nuclear Stress Rule (NSR) which overcomes certain problems found with previous versions, and (ii) to explain the so-called preverbal focus position in Basque in terms of the new NSR and prosodic principles imposed on focused phrases. With respect to the NSR, I argue …

An Arctic dream : the opening of the Northern Sea Route : impact and possibilities for Iceland
… in the North-Atlantic, at the end of the NSR, to become a transshipment port for ongoing cargo destined for North-America and Europe, or even yet a base for Arctic exploration and processing of natural minerals like oil and gas. By examining the technological aspects of NSR navigation, …

Quantification of regularity in RR-interval time series using approximate entropy, sample entropy, and multi-scale entropy
… the RR-interval time series of normal subjects (NSR) from subjects with congestive heart failure (CHF). The study was conducted on the RR-interval data of 44 NSR subjects and 18 CHF subjects. In addition to this, entropy measures of three apparently healthy subjects were calculated during …

Modeling social response to the spread of an infectious disease
… methods to model negative social response (NSR), where a society demonstrates strain associated with a disease. Specifically, we apply real world biosurveillance data on over 11,000 initial events to: 1) describe how negative social response spreads within an outbreak, and 2) analytically …

From Nonproliferation to Counterterrorism and Beyond: U.S. Foreign Policy, Global Governance and the Evolution of the Nuclear Security Regime
… and evolution of the nuclear security regime (NSR) which governs programs, policies and norms associated with the protection of nuclear and radiological materials that sub-state groups might seek to acquire for use in a terrorist attack. The regime is unique in the security field in that it is …

NOx Removal by LNT-SCR Dual-layer Catalysts
… the progress of NOx storage and reduction (NSR) technology. NOx is stored in a lean NOx trap (LNT) catalyst during fuel-lean mode and reduced to N2 during fuel-rich mode. First, we investigated the impact of ceria on NSR in an Pt/Ce LNT catalyst. The physisorbed oxygen over the …

Electric Organ Discharge Frequency Modulations Evoked in Response to Jamming Stimuli in the Weakly Electric Brown Ghost Knifefish (Apteronotus Leptorynchus)
… been referred to as the non-selective response (NSR). When the sign of the clamped stimulus is switched to a -DF condition the animal performs a JAR that appears to ride on top of the modulations of the NSR. However, the repeated switching of the sign of the DF has made it difficult to delineate …

The Effect of Stretching Regimes on Stride Length and Range of Motion of the Equine Trot
… (3DSR) and a control, no stretching regime (NSR). Baseline measurements of SL and ROM in trot (in hand) were obtained prior to treatment using two-dimensional video analysis. The two stretching regimes were applied for eight weeks. SL and ROM data were collected at weeks 0, 2, 4, 6, 8, 9, 10 …

Computational and Pharmacological Approaches to Design Novel Allosteric Thymidylate Synthase Inhibitors
… <p> Firstly, a new nucleotide stress response (NSR) assay was developed and validated for providing a screening platform to identify lead allosteric molecules. The assay measures the uptake of a fluorescent nucleoside analog, which was shown to correlate with TS inhibition induced by direct and …
