Latent variable interaction in structural equation models
… model were studied: (1) Factor Score Regression (FSR) treats factor score estimates for latent variables, and their product, as predictors. (2) Kenny and Judd's (1984) Product Indicators Approach (PIA) defines an interaction latent variable whose indicators are cross-products of indicators of the …

Sulfite reductase and thioredoxin in oxidative stress responses of methanogenic archaea
… named F420-dependent sulfite reductase (Fsr), for the detoxification of SO32- that is produced outside the cell from a reaction between oxygen and sulfide. This reaction occurred during early oxygenation of Earth and continues to occur in deep-sea hydrothermal vents. Fsr, a flavoprotein, …

Identification and Characterization of Aer, an Energy Sensor in Escherichia Coli
… were eliminated. When both <em>aer</em> and <em>fsr</em> were inactivated, aerotaxis, redox taxis and glycerol taxis were completely abolished. Expressing Aer in aer fsr cells restored aerotaxis responses and the duration of responses progressively lengthened with the amount of Aer …

Solid state nuclear magnetic resonance methodology and applications to structure determination of peptides, proteins and amyloid fibrils
… selective rotational-echo double-resonance (FSR) and three-dimensional transferred-echo double-resonance (3D TEDOR) methods for carbon-nitrogen distance measurements in (U-'3C,S5N)-labeled peptides and proteins are described. FSR employs frequency selective Gaussian pulses in combination with …

Ultrabright source of polarization-entangled photons from cavity-enhanced downconversion
… a visibility of 75% when near the ideal equal-FSR operating point, where the pairs are in the biphoton triplet state. When detuned to have unequal FSR the output pairs show the an interference dip behavior consisting of a combination of triplet and singlet states that depends on the time …

An evaluation of domestic food hygiene and food preparation practices
… handling behaviour, the Food Safety Risk Score, (FSR) was devised. The FSR score indicated the extent of the use of appropriate control measures during food preparation. The higher the score the greater the risk of unsafe food being produced. Scores expressed as a percentage, ranged from 0 to 65% …

Novel Electron Transfer Systems in Hyperthermophilic Methanogenic and Anaerobic Methanotrophic Archaea: F420-dependent Nitrite Reductase and [Fe-S] Cluster Assembling Thioredoxin
… strategies, an F420-dependent sulfite reductase (Fsr), deazaflavin-dependent flavin-containing thioredoxin reductase (DFTR), and a thioredoxin (Trx) homolog with a new function. These proteins are involved in redox reactions, and the research presented here deals with the biochemistry of an Fsr …

Iterative uncertainty reduction via Monte Carlo simulation : a streamlined life cycle assessment case study
… model uncertainty is False Error Rate (FSR), defined here as the confusion between two engines that differ in energy use by 10%. Initially the FSR is 21%, dropping to 6.1% after 20 parameters are resolved, and stabilizing at 5.8% after 39 parameters are resolved. The case study …

Effect of early grain feeding of steers on postabsorptive capacity to utilize acetate and glucose
… rates or palmitate fractional synthesis rates (FSR). Acetate turnover and palmitate FSR from acetate were greater than the corresponding rates from glucose. There were no differences in preference for acetate or glucose among the fat depots. In conclusion, phosphorylation ratios of signaling …

Next-Generation Photonic Signal Processors
… is limited by the free spectral range (FSR) of photonic weights. Additionally, their energy efficiency and speed are limited by thermal weights and electronic memory, necessitating regular electronic-optical transitions. Their reliance on a single weight type also restricts their …

Dietary cholesterol in graded amounts : threshold to ceiling effects upon plasma free cholesterol synthesis, equilibration and circulation levels in humans
… was determined as the fractional synthetic rate (FSR)of the rapid exchangeable pool calculated by deuterium incorporation from body water into plasma free cholesterol over 24 hours. RBC cholesterol deuterium incorporation was also compared to that of plasma free cholesterol. Plasma cholesterol was …

A Framework for Digital Investigation of Peer-to-Peer (P2P) Networks. An Investigation into the Security Challenges and Vulnerabilities of Peer-to-Peer Networks and the Design of a Standard Validated Digital Forensic Model for Network Investigations
… Forensic Science Regulator Guidance – 218 (FSR-G-218), and Forensic Science Regulator Guidance – 201 (FSR-G-201) methodologies. The solution was evaluated using a realistic P2P investigation and showed accurate load distribution and reliable digital evidence.

Automated wavelength recovery for silicon photonics
… direct WDM across an uncorrupted 5.3 THz FSR. We have introduced heater elements inside a new single mode filter, a LRM filter, successfully. The LRM filter achieved high-efficiency (3.3[mu]W/GHz) and high-speed ([tau]f ~1.6 [mu]s) thermal tuning and maintained signal integrity with record …

Design and Performance Analysis of Next Generation Heterogeneous Cellular Networks for the Internet of Things
… allocation schemes, full spectrum reuse (FSR) and orthogonal spectrum partition (OSP), for uplink two-hop IoT networks. We develop constraint gradient ascent optimization algorithms to obtain the optimal aggregator association bias (for the FSR scheme) and the optimal joint spectrum …

Probable maximum flooding using quantitative weather radar
… with the storm model than suggested by the NERC FSR (current UK guidelines), the overall volume of rainfall is slightly greater resulting in differences in the maximum storage requirement of the reservoir.

QSAR modeling of chemical penetration enhancers using novel replacement algorithms
… algorithms: forward stepwise regression (FSR), replacement (RM) and enhanced replacement (ERM) techniques. The first two methods yield equations with poor predictive power. The enhanced replacement method gives the best results, which meet cross-validation criteria: q^2 = 0.79, 0.63 and …

A Versatile Method of Resolution Enhancement for Tactile Sensor Array Used as Synthetic Skin: Modeling and Implementation
… robotic system, a 16 x 10 force sensing array (FSR) is adopted. The force was first measured by a scanning data acquisition device integrated by a synthesized electronic circuit, DAQ station and an interface developed using MATLAB. The acquired two dimensional measurements were then processed by …

CONTACT PRESSURE MEASUREMENT
… of these sensors called Force Sensing Resistors (FSRs) were tested. The resistance of the sensors were found to drop with an threshold in the applied pressure when the resistance of the sensor suddenly drops to a much lower value resulting in a "switch like" response. The saturation pressure of …
