Wideband Spatial Channel Model for MIMO Systems at 5 GHz in Indoor and Outdoor Environments (2006)

This work presents a spatial channel model developed within the EC WINNER project. The channel model is mainly based on double-directional measurement campaigns carried out in the 5 GHz ISM band with bandwidths of up to 120 MHz. The model is based on a unified structure for indoor and outdoor environment. It covers 6 different propagation scenarios, namely indoor small office, indoor hall, urban microcell, urban macrocell, suburban macrocell, and rural environment. Both line-of-sight (LOS) and non-line-of-sight (NLOS) propagation conditions are modeled

Synthesis of heat exchanger networks at subambient conditions with compression and expansion of process streams (2010)

Abstract This article presents an optimization formulation for the synthesis of heat exchanger networks where pressure levels of process streams can be adjusted to improve heat integration. Especially important at subambient conditions, this allows for the interconversion of work, temperature, and pressure‐based exergy and leads to reduced usage of expensive cold utility. Furthermore, stream temperatures and pressures are tuned for close tracking of the composite curves yielding increased exergy efficiency. The formulation is showcased on a simple example and applied to a case study drawn from the design of an offshore natural gas liquefaction process. Aided by the optimization, it is demonstrated how the process can extract exergy from liquid nitrogen and carbon dioxide streams to support the liquefaction of a natural gas stream without additional utilities. This process is part of a liquefied energy chain, which, supplies natural gas for power generation while facilitating carbon dioxide sequestration. © 2010 American Institute of Chemical Engineers AIChE J, 2011
Extracting the model parameters of non-ideal junctions based on explicit analytical solutions of I-V characteristics (2005)

We present a new method to extract the intrinsic and extrinsic model parameters of semiconductor junctions containing parasitic resistance and shunt conductance. The method, which is based on a previously defined Integral Difference Function D uses the exact explicit analytical solutions of the I-V characteristics. The presence of Lambert W function terms in the explicit analytical solutions would make parameter extraction by direct numerical fitting cumbersome. However, the resulting D is reduced to a purely algebraic equation from whose coefficients the intrinsic and extrinsic model parameters are then readily determined. The procedure is illustrated for four cases of parasitic series resistance-shunt conductance combinations, and applied to synthetic l-V characteristics to illustrate the computation process.
Frequencies of Apolipoprotein A4 Gene Polymorphisms and Association with Serum Lipid Concentrations in Two Healthy Spanish Populations (2004)

Apolipoprotein A4 (apoA4) plays a role in intestinal lipid absorption. Several experimental interventions have shown that common variations at residues 347 (Thr --> Ser) and 360 (Gln --> His) on apoA4 are associated with differences in plasma lipid response to dietary fat; however, association studies between these variants and plasma lipid concentrations in populations reveal mixed results. We examined the effects of these polymorphisms in 758 randomly selected subjects (mean age 36.7+/-9.5 years) from 2 Spanish regions differing in latitude and fat intake: Aragón and Comunidad Valenciana. Subjects were matched one to one by sex and age. Frequencies for the less common alleles were similar in both regions: 0.096 (95% CI: 0.111-0.081) for codon 360 and 0.196 (95% CI: 0.216-0.176) for codon 347. In men and women there was no association between the codon 360 polymorphism and total cholesterol or triglyceride levels. However, subjects carrying the 360His allele had low-density lipoprotein (LDL) cholesterol concentrations statistically lower than homozygotes for the 360Gln allele, even after further adjustment for sex, age, region, body mass index, and APOE polymorphism (p = 0.043). The less common allele at codon 347 (the 347Ser allele) was associated with increased LDL-cholesterol concentrations with a clear gene-dosage effect after multivariate adjustment (p = 0.029). Although these polymorphisms showed no heterogeneity by geographic region, the magnitude of the effect was higher in subjects from Aragón compared with the Comunidad Valenciana, suggesting a possible influence of the higher fat intake in Aragón. In the combined association analysis subjects with the 360Gln/347Ser pseudohaplotype had the highest LDL-cholesterol concentrations, supporting the antagonistic effect between the 360His and the 347Ser alleles on this trait.

Effect of Direct Current Pulse Discharge on Electrical Resistivity of Copper and Iron Powder Compacts (1997)

The relationship between the number of pulses and the specific resistivity for the copper and iron powder compacts has been investigated to reveal the phenomena which are caused between powder particles in the early stage in the spark sintering process. The values of specific resistivity of the both powder compacts decrease with increasing the number of pulses, and the rates of decrease of specific resistivity increase with decreasing applied punch pressures. The limited variations of the relative densities of compacts are observed in the continuously pulse discharge process. Therefore, it is considered that the specific resistivity of compacts are decreased, not because their relative densities are changed but because the properties of the contact area between powder particles are changed by the pulse discharge. Where, this change of the properties is caused by the dielectric breakdown of the oxide film between the powder particle surfaces in the pulse discharge process. The metallic contact parts are created between the powder particles after this dielectric breakdown. It is suggested on the basis of the simple model of electric resistance of a compact that the fraction of the metallic contact area created by the dielectric breakdown of the oxide film is extremely small. Furthermore, it is assumed on the basis of the first order equation of the chemical reaction that the rate of the creation of the metallic contact area between powder particles per pulse discharge is proportional to the fraction of the contact area consisting of an oxide film between particles. The relationship between the number of pulses and the specific resistivity of compacts can be explained quantitatively by this assumption.

The goal is to identify the antenna technology and the antenna parameters that allow for the improvement of the performance of MIMO systems.
Measurement of Vertical Track Deflection from a Moving Rail Car (2013)

The University of Nebraska has been conducting research sponsored by the Federal Railroad Administration’s Office of Research and Development to develop a system that measures vertical track deflection/modulus from a moving rail car. Previous work has suggested the system can find critical maintenance problems not found by other inspection methods including standard track geometry. The University of Nebraska system uses cameras and lasers to measure a portion of the track deflection basin, and this measurement is used to estimate vertical rail deflection and/or track modulus. This report presents the measurement system along with development of the theory behind the measurement to support diagnosis of track conditions. The results of significant field testing are presented, including the results of a test designed to verify the accuracy of the measurement. A Finite Element Analysis of the measurement is presented along with several variations on closed form solution analysis, based on beam on elastic foundation as well as a discrete support model for rail. The University of Nebraska system has identified several critical maintenance problems not found by other inspection methods, and all previous studies indicate that measuring track deflection provides unique and valuable insight to track conditions that can improve inspection, maintenance, and safety. Finally, some guidelines are suggested for development of thresholds to guide data interpretation and track condition assessment, but more study and tests are needed to better define threshold criteria.
Characterization of Uncoated Stainless Steel as Proton Exchange Membrane Fuel Cell Bipolar Plates Material (2011)

Abstract Thanks to their high conductivity, important gas tightness, good corrosion resistance, and low‐cost manufacturing pathways, stainless steels are considered as good candidates for proton exchange membrane fuel cell (PEMFC) bipolar plates materials. In this study, a proprietary alloy was identified as very promising: its initial electrical contact resistance (ECR) with the gas diffusion layer was low, while its corrosion resistance in simulated PEMFC environment was sufficient. Furthermore, the ECR did not increase dramatically during long‐term potentiostatic and potentiodynamic polarizations in simulated PEMFC cathode and anode environments. Finally, the stainless steel was successfully tested for 3,000 h in a commercial system using a 16‐cell stack, without detrimental cell voltage losses.
Pharmacologic Preservation of Renal Mass and Function in Obstructive Uropathy (1982)

Unilateral ureteral obstruction for 1, 2 and 3 week intervals in rats resulted in a significant loss of renal mass and function as measured 3 months following relief of the obstruction. Inhibition of angiotensin II production by the administration of captopril during the period of obstruction resulted in significant preservation of both renal mass and function. Inhibition of the prostaglandin-thromboxane system with the cyclooxygenase inhibitor. indomethacin, resulted in a lesser degree of preservation of renal function, but had no beneficial effect on renal mass. These experiments suggest that the renin-angiotensin and prostaglandin-thromboxane systems play a significant role in the loss of renal function from obstructive uropathy. Moreover, they demonstrate that renal function is better maintained if these hormonal systems are pharmacologically inhibited during obstruction.
A Combined 3D/Lumped Modeling Approach to Ammonia SCR After-treatment Systems: Application to Mixer Designs (2006)

&lt;div class="htmlview paragraph"&gt;In practical applications of ammonia SCR aftertreatment systems using urea as the reductant storage compound, one major difficulty is the often constrained packaging envelope. As a consequence, complete mixing of the urea solution into the exhaust gas stream as well as uniform flow and reductant distribution profiles across the catalyst inlet face are difficult to achieve.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;This paper discusses a modeling approach, where a combination of 3D CFD and a lumped parameter SCR model enables the prediction of system performance, even with non-uniform exhaust flow and ammonia distribution profiles. From the urea injection nozzle to SCR catalyst exit, each step in the modeling process is described and validated individually. Finally the modeling approach was applied to a design study where the performance of a range of urea-exhaust gas mixing sections was evaluated.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;The application to the design study shows that this combination of tools, CFD and lumped parameter SCR model, gives accurate predictions of the effects of design changes to the actual hardware on the overall performance.&lt;/div&gt;
The Influence of the Torsional Vibration of Ballscrew on the Stability of NC Servo Drive System. (1999)

The Influence of the Torsional Vibration of Ballscrew on the Stability of NC Servo Drive System Jun FUJITA, Sadaji HAYAMA, Minoru HAMAMURA, Yoshiaki KAKINO, Atsushi MATSUBARA and Satoshi OHWAKI The influence of the torsional vibration of ballscrew on the stability of NC servo drive system has been studied in this paper. Theoretical analysis using mathematical model of the baliscrew drive system shows the possibility of the unstability of servo drive system due to the interacted effect of torsional vibration, the dead time and phase lag of the 1st order filter. Experimental analysis using the existing NC drive system shows fairly good coincidence with the calculated results.

Crossed-beam measurements of differential cross sections for elastic scattering and charge exchange in low-energy<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msup><mml:mrow><mml:mi mathvariant="normal">Ar</mml:mi></mml:mrow><mml:mrow><mml:mo>+</mml:mo></mml:mrow></mml:msup></mml:mrow></mml:math>-Ar collisions (1978)

Differential cross sections for ${\mathrm{Ar}}^{+}$-Ar collisions have been measured at four laboratory energies in the range 2.7-20 eV and laboratory scattering angles from 2 to 90 deg using a crossed-beam apparatus. Data are presented as absolute differential cross sections in the center-of-mass coordinate system as functions of relative translational energy and center-of-mass scattering angle. The data presented should be sufficient to allow rather precise determination of the long-range portion of the ${\mathrm{Ar}}^{+}$-Ar interaction potentials. Preliminary interpretation of the rainbow scattering data gives a dissociation energy ${D}_{e}$ for the $^{2}\ensuremath{\Sigma}_{u}^{+}$ state of ${\mathrm{Ar}}_{2}^{+}$ of 1.40\ifmmode\pm\else\textpm\fi{}0.05 eV.

Spontaneous neonatal arterial thromboembolism (2013)

Neonatal spontaneous arterial thromboembolism is a rare phenomenon with a high risk of morbidity and mortality. Currently, there is little information regarding common risk factors, diagnostic strategies, therapeutic interventions, and outcomes of this condition. The objective was to nucleate the best evidence regarding the disorder in order to facilitate early detection and treatment recommendations and document adverse outcomes. Web of Science, PubMed, Medline, CINAHL, Cochrane Databases, DARE, and OVID databases were searched using the following keywords: 'arterial' AND 'thrombus' OR 'thrombosis' OR 'thromboembolism' OR 'embolism' AND 'spontaneous' AND 'at birth' OR 'newborn' OR 'neonatal' OR 'fetal' AND 'umbilical cord' OR 'umbilical wall necrosis' AND 'coagulation abnormality' OR 'placenta bits' OR 'ischemic limbs'. The search yielded 172 articles, all of which were case series or single case descriptions. Twenty-seven met inclusion criteria, with a total of 53 newborns and 30 newborn pathology reports. Ultrasound was the preferred method of diagnosis and thromboembolic locations varied with the most common site being umbilical, resulting in embolism and vascular compromise. Treatment interventions and drug dosages were not standardized and ranged from use of anticoagulants to surgery and hyperbaric oxygen. The reported mortality rate was 32.8%. Recurring etiological features facilitated identification of possible sequences of events contributing to the disorder. The literature lacks empirical evidence to affirm causes and predisposing risk factors for timely diagnosis and effective treatment of spontaneous neonatal arterial thromboembolism. Further research is needed to clearly establish the causes and the efficacy of specific treatment options.
Modeling Uncertainty-Seeking Behavior Mediated by Cholinergic Influence on Dopamine (2019)

Abstract Recent findings suggest that acetylcholine mediates uncertainty-seeking behaviors through its projection to dopamine neurons – another neuromodulatory system known for its major implication in reinforcement learning and decision-making. In this paper, we propose a leaky-integrate-and-fire model of this mechanism. It implements a softmax-like selection with an uncertainty bonus by a cholinergic drive to dopaminergic neurons, which in turn influence synaptic currents of downstream neurons. The model is able to reproduce experimental data in two decision-making tasks. It also predicts that i) in the absence of cholinergic input, dopaminergic activity would not correlate with uncertainty, and that ii) the adaptive advantage brought by the implemented uncertainty-seeking mechanism is most useful when sources of reward are not highly uncertain. Moreover, this modeling work allows us to propose novel experiments which might shed new light on the role of acetylcholine in both random and directed exploration. Overall, this study thus contributes to a more comprehensive understanding of the roles of the cholinergic system and its involvement in decision-making in particular.
Pre-treatment of cellulose by cellobiose dehydrogenase increases the degradation rate by hydrolytic cellulases (2007)

Cellobiose dehydrogenase (CDH) is an extra-cellular flavocytochrome with unknown biological function, produced by various wood degrading fungi. In the presence of Fe(III) and cellobiose, CDH produces hydroxyl radicals through a Fenton-type reaction. Treatment of cellulose with CDH, cellobiose, hydrogen peroxide and ferriacetate decreased cellulose's polymerization degree and increased its degradability for different functional types of hydrolytic cellulases, except for an exo-enzyme working from the reducing end. This suggests a biological role for CDH in fungal cellulose degradation, possibly by activating the cellulose for hydrolytic cellulases by depolymerization and disturbance of the hydrogen bonding pattern in cellulose.

Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at square root of s = 7 TeV are measured with the inner tracking system of the CMS detector at the LHC. The charged-hadron yield is obtained by counting the number of reconstructed hits, hit pairs, and fully reconstructed charged-particle tracks. The combination of the three methods gives a charged-particle multiplicity per unit of pseudorapidity dN(ch)/dη|(|η|<0.5) = 5.78 ± 0.01(stat) ± 0.23(syst) for non-single-diffractive events, higher than predicted by commonly used models. The relative increase in charged-particle multiplicity from square root of s = 0.9 to 7 TeV is [66.1 ± 1.0(stat) ± 4.2(syst)]%. The mean transverse momentum is measured to be 0.545 ± 0.005(stat) ± 0.015(syst) GeV/c. The results are compared with similar measurements at lower energies.
Enhanced optical nonlinear performance with 2D graphene oxide thin films integrated with CMOS compatible devices (2021)

We report enhanced nonlinear optics in complementary metal-oxide-semiconductor (CMOS) compatible photonic platforms through the use of layered two-dimensional (2D) graphene oxide (GO) films. We integrate GO films with silicon-on-insulator nanowires (SOI), high index doped silica glass (Hydex) and silicon nitride (SiN) waveguides and ring resonators, to demonstrate an enhanced optical nonlinearity including Kerr nonlinearity and four-wave mixing (FWM). The GO films are integrated using a large-area, transfer-free, layer-by-layer method while the film placement and size are controlled by photolithography. In SOI nanowires we observe a dramatic enhancement in both the Kerr nonlinearity and nonlinear figure of merit (FOM) due to the highly nonlinear GO films. Self-phase modulation (SPM) measurements show significant spectral broadening enhancement for SOI nanowires coated with patterned films of GO. The dependence of GO’s Kerr nonlinearity on layer number and pulse energy shows trends of the layered GO films from 2D to quasi bulk-like behavior. The nonlinear parameter of GO coated SOI nanowires is increased 16 folds, with the nonlinear FOM increasing over 20 times to FOM &amp;gt; 5. We also observe an improved FWM efficiency in SiN waveguides integrated with 2D layered GO films. FWM measurements for samples with different numbers of GO layers and at different pump powers are performed, achieving up to ≈7.3 dB conversion efficiency (CE) enhancement for a uniformly coated device with 1 layer of GO and ≈9.1 dB for a patterned device with 5 layers of GO. These results reveal the strong potential of GO films to improve the nonlinear optics of silicon, Hydex and SiN photonic devices.
