Efficient algorithm for adjustment of adaptive predistorter in OFDM transmitter (2002)

Adaptive predistortion is a technique which is aimed at compensation of nonlinear distortion introduced by a high power amplifier (HPA). This paper presents a simple method of acceleration of the adaptive algorithm of the HPA predistorter. The values of the predistorter complex gain stored in RAM and depending on the input signal amplitude are efficiently modified nor only in the address indicated by the current signal amplitude but also in the whole range of locations around it. The simulation results of the predistorter's adaptation show a visible improvement in the convergence rate as compared with the standard gradient algorithm.
Quantitative Phase Imaging using Entangled Photon Pairs (2014)

We experimentally demonstrate phase imaging using entangled photons and transport-of-intensity methods. We show that the reconstruction of an unknown phase object from quantum light is more sensitive and less noisy than that of classical illumination.
Analysis of upper extremity response under side air bag loading (2001)

Computer simulations, dummy experiments with a new enhanced upper extremity, and small female cadaver experiments were used to analyze the small female upper extremity response under side air bag loading. After establishing the initial position, three tests were performed with the 5th percentile female hybrid III dummy, and six experiments with small female cadaver subjects. A new 5th percentile female enhanced upper extremity was developed for the dummy experiments that included a two-axis wrist load cell in addition to the existing six-axis load cells in both the forearm and humerus. Forearm pronation was also included in the new dummy upper extremity to increase the biofidelity of the interaction with the handgrip. Instrumentation for both the cadaver and dummy tests included accelerometers and magnetohydrodynamic angular rate sensors on the forearm, humerus, upper and lower spine. In order to quantify the applied loads to the cadaver hand and wrist from the handgrip, the handgrip was mounted to the door through a five-axis load cell and instrumented with accelerometers for inertial compensation. All six of the cadaver tests resulted in upper extremity injuries, with comminuted mid-shaft humerus fractures (AIS 3) observed in two tests. Osteochondral fractures of the elbow joint surfaces (AIS 2) were seen in four of the six cadaver tests. Two wrist injuries were observed including a transverse fracture of the distal radius (AIS 2) and an osteochondral fracture of the lunate carpal bone (AIS 2). The results from the six cadaver tests presented in this study were combined with the results from twelve previous cadaver tests. A multivariate logistic regression analysis was performed to investigate the correlation between observed injuries and measured occupant response. Using inertially compensated force measurements from the dummy mid-shaft forearm load cell, the linear combination of elbow axial (FZ) and shear (FX) was significantly (p = 0.05) correlated to the observed elbow injuries.

2075 Papillary muscles and trabeculations significantly impact ventricular volume, ejection fraction, and regurgitation assessment by cardiovascular magnetic resonance in patients with hypertrophic cardiomyopathy (2008)

Introduction Measurement of valvular regurgitation is important in patients with hypertrophic cardiomyopathy (HCM). Using a cardiovascular magnetic resonance (CMR) manual partition method that includes papillary muscles and trabeculations as part of the ventricular cavity volume combined with phase velocity methods, the regurgitant fraction correlates well with assessment by Doppler echocardiography in patients with normal wall thickness. However, inclusion of papillary muscles and trabeculations as components of left ventricular (LV) mass may provide more accurate results. The impact of papillary muscle and trabeculation partitioning may be particularly prominent among patients with HCM for whom inclusion of these structures in the ventricular cavity volume may result in an overestimation of ventricular volumes and quantified valvular regurgitation.
Large pilot plant alternatives for scaleup of the catalytic coal gasification process. Final report (1979)

This is the final report for US Department of Energy Contract No. EX-76-C-01-2480, Scaleup Requirements of the Exxon Catalyzed Coal Gasification Process. The objective was to develop the information necessary to determine if an existing DOE large pilot plant could be used to obtain the scaleup data necessary to design and construct a Catalytic Coal Gasification (CCG) pioneer plant with acceptable risk. A pioneer plant is a stand-alone facility, whose primary function is to operate as a profitable commercial venture. The pioneer plant would contain all equipment of full commercial size, as defined by the requirements for an optimum-sized commercial plant. However, the pioneer plant could have a single train of equipment in some or all of the plant sections. The three tasks contained in this contract are discussed: study design and cost estimate for a grass-roots large pilot plant; selection of the preferred existing pilot plant; and study design and cost estimate for revamp of the preferred existing pilot plant.
Development of Bioorthogonal Reactions and Their Applications in Bioconjugation (2015)

Biomolecule labeling using chemical probes with specific biological activities has played important roles for the elucidation of complicated biological processes. Selective bioconjugation strategies are highly-demanded in the construction of various small-molecule probes to explore complex biological systems. Bioorthogonal reactions that undergo fast and selective ligation under bio-compatible conditions have found diverse applications in the development of new bioconjugation strategies. The development of new bioorthogonal reactions in the past decade has been summarized with comments on their potentials as bioconjugation method in the construction of various biological probes for investigating their target biomolecules. For the applications of bioorthogonal reactions in the site-selective biomolecule conjugation, examples have been presented on the bioconjugation of protein, glycan, nucleic acids and lipids.
High-Speed Observation of a Cavitating Jet in Air (2005)

The use of cavitation impact is a practical method for improving the fatigue strength of metals in the same way as shot peening. In the case of peening using cavitation impact, cavitation is produced by a high-speed submerged water jet with cavitation, i.e., a cavitating jet. A cavitating jet in air was successfully generated by injecting a high-speed water jet into a low-speed water jet injected into air using a concentric nozzle. In order to investigate the various appearances of cavitating jets in air, an observation was carried out using high-speed photography and high-speed video recording. In this study, periodical shading of the cavitation cloud was observed and the frequency of the shading was found to be a function of the injection pressure of the low-speed water jet. Unsteadiness of the low-speed water jet, which is related to the periodical shading of the cloud, was also observed.

Arabidopsis Microarray Service Facilities (2000)

Now that we know the complete sequence of the Arabidopsis genome, how can plant biologists most effectively use this 130 million-bp database to move toward fuller understanding of plants? Microarray technology is one of a collection of tools that can accelerate our transition from raw data toward broader understanding. It is clear that knowing a gene sequence often does not tell us its function. In fact, more than 30% of the approximately 25,000 genes of Arabidopsis show no homology to genes of known or hypothesized function. Thousands of additional genes are only identified as members of classes such as protein kinases or transcription factors, but no information is available about their specific roles. The knowledge that there are 6,000 to 10,000 plant genes with functions still to be discovered helps to define our level of ignorance and challenges us to find new tools for investigating gene function. It is an exciting challenge because uncovering the function of these poorly understood genes is likely to lead to a very rich harvest of new discoveries. To help meet this challenge, the Arabidopsis Functional Genomics Consortium (AFGC) was established to coordinate the study of gene function by two synergistic methods: microarray gene expression profiling and gene knockout mutagenesis. AFGC is comprised of a team of investigators from four institutions.
Voxel based annealed particle filtering for markerless 3D articulated motion capture (2009)

This paper presents a view-independent approach to markerless human motion capture in low resolution sequences from multiple calibrated and synchronized cameras. Redundancy among cameras is exploited to generate a 3D voxelized representation of the scene and a human body model (HBM) is introduced towards analyzing these data. An annealed particle filtering scheme where every particle encodes an instance of the pose of the HBM is employed. Likelihood between particles and input data is performed using occupancy and surface information and kinematic constrains are imposed in the propagation step towards avoiding impossible poses. Test over the HumanEva annotated dataset yield quantitative results showing the effectiveness of the proposed algorithm.
<title>Measurement of the particulate and water vapor contamination environments of the Midcourse Space Experiment (MSX) spacecraft</title> (1994)

We have designed, fabricated, and tested two flashlamp-based instruments that will characterize the particulate and water vapor contamination environments aboard the Midcourse Space Experiment (MSX) spacecraft: the Xenon Flashlamp and the Krypton Radiometer. These instruments will operate as part of suite of instruments to monitor the MSX contamination environment over its five-year mission. The Xenon Flashlamp illuminates particles in the field of view of the UVISI Wide Field of View Visible Imager, which in turn measures the scattered radiation. The particle measurement can detect particles smaller than 1 micrometers and can measure cross-field particle velocities from 0.5 cm/sec to 50 m/sec. The Krypton Radiometer measures the local water vapor density. VUV radiation from an array of RF-excited krypton lamps photodissociates H<SUB>2</SUB>O in the fields of view of a filtered radiometer and one of the UVISI Spectrographic Imagers. The radiometer and the spectrograph simultaneously measure the intensity of the resulting OH chemiluminescence. The H<SUB>2</SUB>O density is proportional to that intensity. The spectrograph will provide a positive identification of the radiating species. Instrument descriptions as well as ground test and simulation data are presented.

[Functional assessment of coronary stenosis by fractional flow reserve]. (2017)

Revascularization of coronary artery stenosis should be based on the objective evidence of ischemia. Coronary angiography provides excellent spatial and temporal resolution for the visualization of the coronary arteries, but is of limited value in defining the functional significance of a particular lesion.Fractional flow reserve (FFR) has become routine practice in the cardiac catheterization laboratory and is considered nowadays as the gold standard for invasive assessment of physiologic stenosis significance. This paper reviews the concepts behind the coronary physiology and FFR, its practical application and summarizes current evidence from key clinical trials.
On the Hypernuclear Weak Decay Puzzle (2001)

A novel method for the evaluation of hypernuclear non-mesonic (NM) decay rates is developed. It involves a partial wave expansion and has as basic building block the particle-hole shell model, with the Pauli Principle fully included within. The standard strangeness-changing weak ΛN → NN transition potential, involving the exchange of the complete pseudoscalar-vector meson-octet (π,η,K,ρ,ω,K ∗), is used. The corresponding non-relativistic approximation is critically revised, both in momentum and in coordinate spaces. In this way are deduced some specially important parity violating transition operators in the vector-meson exchanges, which have been systematically omitted in the literature. Simple formula, which clearly exhibit the interplay between different mesons in each one of the multipole channels, are presented for the neutron and proton induced decays, Γn and Γp, in 12 Λ C. With the commonly used parametrization, for the one-meson-exchange model (OMEM), the calculated rate ΓNM = Γn + Γp is of the order of the free Λ decay rate Γ0 (Γth NM ∼ = Γ0), as is the experimental one. Yet, neither the measurements for the ratio Γn/p = Γn/Γp, nor that for Γp, are well accounted for by the theory (Γ th n/p ≤ 0.4;Γth p ≥ 0.8Γ0). By varying the OMEM parameters, it is possible to make the n/p ratio to agree with data (Γ th n/p ∼ = 1). The proton induced decay, however, cannot be reconciled with measurements in this way (Γ th p ≥ 0.5Γ0). It is suggested that the OMEM is likely incapable by itself to account for the NM hypernuclear weak decays, and that perhaps it would be necessary to bring into play additional degrees of freedom.

1,3-Dipolar Cycloaddition of Azomethine Ylides with Vinyl Sulfones (2006)

The authors describe a copper(I)- catalyzed enantioselective 1,3-dipolar cycloaddition of azomethine ylides with vinyl sulfones. Almost complete exo selectivity is obtained. An extensive ligand screening was performed with TaniaPhos providing the highest ee. Phenyl vinyl sulfone was found to be the optimal dipolarophile and a variety of substituted dipoles afforded the 3-sulfonyl cycloadducts.
Synthesis of Nanoporous Ni‐Co Mixed Oxides by Thermal Decomposition of Metal‐Cyanide Coordination Polymers (2015)

A straightforward strategy to prepare nanoporous metal oxides with well-defined shapes is highly desirable. Through thermal treatment and a proper selection of metal-cyanide coordination polymers, nanoporous nickel-cobalt mixed oxides with different shapes (i.e., flakes and cubes) can be easily prepared. Our nanoporous materials demonstrate high electrocatalytic activity for oxygen evolution reaction.
Increased Glutamatergic Neurotransmission and Oxidative Stress After Alcohol Withdrawal (1998)

The data suggest that augmentation of excitatory neurotransmission may lead to enhanced oxidative stress, which, in concert with reduced inhibitory neurotransmission, may contribute to the symptoms of ethanol withdrawal and associated neurotoxicity in humans. Whether these abnormalities represent a trait- or state-dependent marker of ethanol dependence remains to be resolved.
Blood flow analysis from angiogram image sequence (2005)

Blood flow and velocity are important physiological parameters, of great value to clinicians. We use X-ray imaging technique to estimate these parameters from image sequence showing propagation of injected contrast agent and with the help of 3D volume of arterial vessel tree. 3D volume is mechanically registered with 2D images so it can be projected on them. Blood flow is of interest in two distinct regions: the artery vessels and the capillary region. Blood flow in artery is based on blood velocity and vessel cross-section area estimation. Blood velocity is obtained by measuring transit time of the contrast agent through the vessel of known length. Vessel length and cross-section area can be measured from the 3D artery volume. Transit time is obtained by measuring time of arrival of contrast agent from 2D image sequence to different parts of the projected vessel. Blood flow at the capillary level is called perfusion and we based our methods on the theory behind perfusion MRI and perfusion CT modalities. Time activity signal of each region is obtained and its characteristics are linked to physiological parameters of interest using maximum slope model. The obtained results seem promising although qualitative rather than quantitative interpretation is more suitable.
Towards an online detection of pedestrian flocks in urban canyons by smoothed spatio-temporal clustering of GPS trajectories (2011)

Detecting pedestrians moving together through public spaces can provide relevant information for many location-based social applications. In this work we present an online method to detect such pedestrian flocks by spatio-temporal clustering of location trajectories. Compared to prior work, our method provides increased robustness against the influence of noisy and missing GPS data often encountered in urban environments. To assess the performance of the method, we record GPS trajectories from ten subjects walking through a city. The data set contains various flock formations and corresponding ground truth information is available. With this data set, we can evaluate the accuracy of our method to detect flocks. Results show that we can detect flocks and their members with an accuracy of 91.3%. We evaluate the influence of noisy and missing location data on the detection accuracy and show that the introduced filtering heuristics provides increased detection accuracy in such realistic situations.
Faculty Opinions recommendation of The 2'-O-methylation status of a single guanosine controls transfer RNA-mediated Toll-like receptor 7 activation or inhibition. (2012)

Foreign RNA serves as pathogen-associated molecular pattern (PAMP) and is a potent immune stimulator for innate immune receptors. However, the role of single bacterial RNA species in immune activation has not been characterized in detail. We analyzed the immunostimulatory potential of transfer RNA (tRNA) from different bacteria. Interestingly, bacterial tRNA induced type I interferon (IFN) and inflammatory cytokines in mouse dendritic cells (DCs) and human peripheral blood mononuclear cells (PBMCs). Cytokine production was TLR7 dependent because TLR7-deficient mouse DCs did not respond and TLR7 inhibitory oligonucleotides inhibited tRNA-mediated activation. However, not all bacterial tRNA induced IFN-α because tRNA from Escherichia coli Nissle 1917 and Thermus thermophilus were non-immunostimulatory. Of note, tRNA from an E. coli knockout strain for tRNA (Gm18)-2'-O-methyltransferase (trmH) regained immunostimulatory potential. Additionally, in vitro methylation of this immunostimulatory Gm18-negative tRNA with recombinant trmH from T. thermophilus abolished its IFN-α inducing potential. More importantly, Gm18-modified tRNA acted as TLR7 antagonist and blocked IFN-α induction of influenza A virus-infected PBMCs. PMID: 22312111
In vivo growth characteristics of leucine and methionine auxotrophic mutants of Mycobacterium bovis BCG generated by transposon mutagenesis (1995)

Insertional mutagenesis in Mycobacterium bovis BCG, a member of the slow-growing M. tuberculosis complex, was accomplished with transposons engineered from the Mycobacterium smegmatis insertion element IS1096. Transposons were created by placing a kanamycin resistance gene in several different positions in IS1096, and the resulting transposons were electroporated into BCG on nonreplicating plasmids. These analyses demonstrated that only one of the two open reading frames was necessary for transposition. A library of insertions was generated. Southern analysis of 23 kanamycin-resistant clones revealed that the transposons had inserted directly, with no evidence of cointegrate formation, into different restriction fragments in each clone. Sequence analysis of nine of the clones revealed junctional direct 8-bp repeats with only a slight similarity in target sites. These results suggest that IS1096-derived transposons transposed into the BCG genome in a relatively random fashion. Three auxotrophs, two for leucine and one for methionine, were isolated from the library of transposon insertions in BCG. They were characterized by sequencing and found to be homologous to the leuD gene of Escherichia coli and a sulfate-binding protein of cyanobacteria, respectively. When inoculated intravenously into C57BL/6 mice, the leucine auxotrophs, in contrast to the parent BCG strain or the methionine auxotroph, showed an inability to grow in vivo and were cleared within 7 weeks from the lungs and spleen.
