<title>Target identification in the time-frequency domain</title> (1996)

This paper addresses the problem of target identification using features extracted from the time-frequency domain. This approach is an attractive alternative to other target recognition schemes because it makes us of the time-dependence of frequency domain signatures or the frequency dependence of time-domain scattering features. The disadvantage, however, is that time-frequency signatures are based on the magnitude squared of the received backscatter signal and are thus characterized by high noise variance. In this paper, we determine the feasibility of radar target identification in the time-frequency domain. The goal is to compare the performance of time-frequency domain target recognition with other schemes that rely on the raw backscatter data. To ensure fairness, we implement the same type of statistical pattern recognition in both domains. We also attempt three types of time-frequency backscatter representations: Wigner-Ville, Bjorn-Jordan, and spectrograms. We use the analytic form of real radar signatures recorded in a compact range environment for different target azimuth positions.
Comparison of a diode pumped Er:YSGG and Er:YAG laser in the bounce geometry at the 3 μm transition (2011)

A comparative study is made of the laser crystals 50 at. % Er:YAG and 50 at. % Er:YSGG. Both lasers are constructed in the bounce geometry with quasi continuous wave (QCW) diode pumping. In Er:YAG, pulse energies of up to ~31mJ, slope efficiency of 12.6% and a red-shift in laser wavelength are observed with a final and dominant wavelength of 2.936μm. In Er:YSGG, higher performance is achieved with pulse energies of ~55mJ, slope efficiency of 20.5% and a single transition wavelength of 2.797μm observed. The study indicates that diode pumped Er:YSGG is a superior laser source at 3μm than Er:YAG and it has greater energy storage potential for Q-switched operation.
FACTS: an approach to unearth legacy contracts (2004)

The large number of contracts in force in an enterprise becomes an important factor in making business decisions. Moreover, an enterprise must be able to respond to events that might affect existing contractual relationships. However, most enterprises do not have the capability to easily manage the life cycle of enterprise contracts. Current solutions bundled into products are typically only efficiently used when applied to new business contracts but not to legacy ones, which often constitute the majority of the contracts in an enterprise. Critical information in such contracts remains buried in the text of these documents, requiring a tedious and costly manual inspection task to extract the information required for their proper management. In this paper we present an approach, called FACTS, to automatically elicit legacy contracts information that enables the effective and efficient management of their lifecycle. The approach is based in the use of two object models in conjunction with information extraction techniques. Once relevant information in a contract is identified, it can either be automatically tagged with XML or simply extracted into a contract facts database. In both cases, relevant contract information becomes readily available through predefined or ad-hoc queries.
Identification of RNA sequence isomer by isotope labeling and LC–MS/MS (2014)

Recently, we developed a method for modified ribonucleic acid (RNA) analysis based on the comparative analysis of RNA digests (CARD). Within this CARD approach, sequence or modification differences between two samples are identified through differential isotopic labeling of two samples. Components present in both samples will each be labeled, yielding doublets in the CARD mass spectrum. Components unique to only one sample should be detected as singlets. A limitation of the prior singlet identification strategy occurs when the two samples contain components of unique sequence but identical base composition. At the first stage of mass spectrometry, these sequence isomers cannot be differentiated and would appear as doublets rather than singlets. However, underlying sequence differences should be detectable by collision-induced dissociation tandem mass spectrometry (CID MS/MS), as y-type product ions will retain the original enzymatically incorporated isotope label. Here, we determine appropriate instrumental conditions that enable CID MS/MS of isotopically labeled ribonuclease T1 (RNase T1) digestion products such that the original isotope label is maintained in the product ion mass spectrum. Next, we demonstrate how y-type product ions can be used to differentiate singlets and doublets from isomer sequences. We were then able to extend the utility of this approach by using CID MS/MS for the confirmation of an expected RNase T1 digestion product within the CARD analysis of an Escherichia coli mutant strain even in the presence of interfering and overlapping digestion products from other transfer RNAs.
On the constrained MUSIC technique (1993)

A constrained MUSIC technique, recently proposed for bearing estimation, is shown to be a version of the beam-space MUSIC. This observation places the constrained MUSIC in a class of bearing estimators whose statistical performance is well understood.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Surface decoration of red blood cells with maleimidophenyl‐polyethylene glycol facilitated by thiolation with iminothiolane: an approach to mask A, B, and D antigens to generate universal red blood cells (2005)

Thiolation-mediated PEGylation of RBCs with Mal-Phe-PEG-5000 and Mal-Phe-PEG-20000 converts Group A Rh(D)+ and B Rh(D)+ RBCs into RBCs with serologic behavior comparable to Group O Rh(D)- RBCs that are considered as universal RBCs for transfusion.
Autonomous manipulation with a general-purpose simple hand (2011)

While complex hands seem to offer generality, simple hands are often more practical. This raises the question: how do generality and simplicity trade off in the design of robot hands? This paper explores the tension between simplicity in hand design and generality in hand function. It raises arguments both for and against simple hands, it considers several familiar examples, and it proposes an approach for autonomous manipulation using a general-purpose but simple hand. We explore the approach in the context of a bin-picking task, focused on grasping, recognition, and localization. The central idea is to use learned knowledge of stable grasp poses as a cue for object recognition and localization. This leads to some novel design criteria, such as minimizing the number of stable grasp poses. Finally, we describe experiments with two prototype hands to perform bin-picking of highlighter markers.

Notice of Removal Soot modeling using quasi-stationary measurement for gasoline engine (2015)

Recently various devices are added to the engine for improvement of fuel consumption and environment protection. The calibration tasks are increasing. The quasi-stationary measurement has proposed as a fast engine measurement method. This measurement is a method to obtain engine characteristics data by slow ramping the parameter. The data can be treated as steady state behavior of the interesting engine responses.
Increased Nitric Oxide Production in Hypotensive Hemodialysis Patients (1996)

A subset of patients on long-term hemodialysis have sustained hypotension, defined as a predialysis systolic pressure of < 100 mmHg. To determine the role of nitric oxide (NO), an important vasodilator, in this condition, the authors measured the plasma levels of nitrite (NO2-) and nitrate (NO3-), the known NO metabolites taken as an index of NO production, in 10 hypotensive patients on long-term hemodialysis. None of them had diabetes, cirrhosis of the liver, congestive heart failure, or infection. Fifteen age and gender-matched normotensive patients on hemodialysis were selected as control subjects. Measurements of plasma levels of nitrite and nitrate based on the Greiss reaction were made. There was no significant difference in hematocrit, serum intact parathyroid hormone, total calcium, inorganic phosphorus, albumin, heart rate, cardiac index, or interdialysis weight gain between these two groups. Plasma nitrite and nitrate levels did not correlate with either predialysis serum creatinine or blood urea nitrogen. The mean arterial pressure (MAP) was significantly lower and plasma nitrite and nitrate levels were significantly higher in chronic hypotensive patients than in normotensive patients (MAP: 68.30 +/- 3.24 mmHg vs 95.20 +/- 2.44 mmHg, p < 0.001; plasma nitrite and nitrate: 72.49 +/- 14.41 mumol/L vs 36.42 +/- 5.45 mumol/L, p < 0.05). In addition, MAP from hypotensive and normotensive patients on hemodialysis was inversely correlated with plasma levels of nitrite and nitrate (r = -0.54, p < 0.01). It was concluded that enhanced NO production in this subset of patients on hemodialysis may contribute to their chronic hypotension.
Metabolic and genomic changes induced by macronutrient composition vs. caloric restriction (2008)

The aim of this study was to investigate differential effects of dietary fat and energy restriction on metabolic and genomic differences in adipose tissue. Eight week‐old C57/BL6 mice were either given free access to a low fat (LF) or high fat (HF) diet, or were initially fed HF for 16 weeks followed by 8‐weeks of caloric restriction (HFR, 70% of HF ad lib caloric intake). As expected, the HF group gained more body and fat mass than the LF group, and energy restriction resulted in loss of body fat and weight. Although fasting glycemia was comparable between the 3 groups, HFR group had lower insulinemia, compared to HF and LF groups. Analysis of serum adipokines indicated that plasma leptin levels were lowest in HFR mice; surprisingly, plasma adiponectin levels were also lowest in this group, despite their apparent enhanced insulin sensitivity. Microarray analysis of gonadal fat indicated upregulation of genes involved in fatty acid synthesis, oxidation and glycolysis in the LF group. Differentially expressed genes in the HF group included several oncogenes, while those in HFR group included genes related to insulin sensitivity and apoptosis. These studies demonstrate differential effects of low fat diet and caloric restriction on fatness and insulin sensitivity, and on the molecular responses in adipose tissue.
Time-resolved fluorometric and differential scanning calorimetric investigation of dehydroergosterol in 1-stearoyl-2-capryl phosphatidylcholine bilayers (1990)

Thermal and dynamic properties of dehydroergosterol (DHE) in 1-stearoyl-2-capryl-sn-glycero-3-phosphocholine [C(18):C(10)PC] have been studied by differential scanning calorimetry (DSC) and multifrequency phase-modulation fluorometry. C(18):C(10)PC is an asymmetric mixed-chain phosphatidylcholine known to form highly ordered mixed interdigitated bilayers below the maximal transition temperature, Tm, and partially interdigitated bilayers above Tm. This lipid system is thus unique in assessing the interactions between sterols and interdigitated lipid bilayers. DHE is a fluorescent analogue of cholesterol shown in previous studies to behave like cholesterol in noninterdigitated symmetric diacylphosphatidylcholines. DSC data show that DHE exhibits similar characteristics to cholesterol [Chong & Choate (1989) Biophys. J. 55, 551-556] in C(18):C(10)PC bilayers. DHE abolishes the phase transition of C(18):C(10)PC at 27 mol % compared to 25 mol % for cholesterol and decreases Tm, the onset temperature (To), and the completion temperature (Tc), at a similar rate to cholesterol at about -0.25 degrees C per mole percent DHE. Fluorescence data show that the rotational motion of DHE can be described by a hindered anisotropic model. In the gel state of C(18):C(10)PC, the rotational correlation of DHE decreases monotonically with increasing DHE content up to 24 mol %, suggesting that DHE causes a disordering/spacing effect on the packing of mixed interdigitated C(18):C(10)PC bilayers. The rotational correlation time undergoes an abrupt increase from 24 to 27 mol % DHE. Abrupt changes in the DSC parameters were also observed in the neighborhood of 27 mol %, suggesting that major reorganization takes place around this concentration.(ABSTRACT TRUNCATED AT 250 WORDS)
Fast method for computation of the static pressure field in stenotic geometries by PC MRI (2003)

In this paper a very fast algorithm for non-invasive intra-vascular pressure measurement using Phase-Contrast MRI data is introduced. A noise robust finite difference numerical method has been developed to quickly calculate the relative static pressure in steady flow by using the Navier-Stokes equation in axisymmetric geometries. We show that in such geometries, pressure calculation may be performed in less than two minutes and by using a single PC MR slice containing the axis of symmetry, in turn resulting in dramatic reductions in the acquisition time. The method has been validated under a variety of additive noise conditions with computational fluid dynamics (CFD) flow simulations within phantom geometries. Effects of noise, resolution, and velocity (flow) are discussed.
A Generalized Algorithm for the Generation of Correlated Rayleigh Fading Envelopes in Wireless Channels (2005)

Although generation of correlated Rayleigh fading envelopes has been intensively considered in the literature, all conventional methods have their own shortcomings, which seriously impede their applicability. A very general, straightforward algorithm for the generation of an arbitrary number of Rayleigh envelopes with any desired, equal or unequal power, in wireless channels either with or without Doppler frequency shifts, is proposed. The proposed algorithm can be applied to the case of spatial correlation, such as with multiple antennas in multiple-input multiple-output (MIMO) systems, or spectral correlation between the random processes like in orthogonal frequency-division multiplexing (OFDM) systems. It can also be used for generating correlated Rayleigh fading envelopes in either discrete-time instants or a real-time scenario. Besides being more generalized, our proposed algorithm is more precise, while overcoming all shortcomings of the conventional methods.
Amyloid Fibrils: Nanoscale Heterogeneity of the Molecular Structure of Individual hIAPP Amyloid Fibrils Revealed with Tip‐Enhanced Raman Spectroscopy (Small 33/2015) (2015)

Many diseases, including type 2 diabetes, are linked to the pathological deposition of nanoscale, fibrillar protein aggregates called amyloids. Since the surface of amyloid fibrils plays a key role in amyloid toxicity and membrane damage, knowledge of the surface structure is essential. On page 4131, V. Deckert, G. H. Koenderink, and co-workers probe the molecular structure and amino acid residue composition with tipenhanced Raman spectroscopy. The surface of amyloid fibrils contains mainly unstructured or α-helical structures, in contrast to the core, which is dominated by β-sheets.
Epidemiological survey of HIV infection in the Veneto region of Italy. (1987)

A seroepidemiological survey of the Veneto region was undertaken to determine the prevalence of HIV antibodies in the sera of subjects belonging to known risk groups for AIDS and related conditions. The sera were tested by ELISA and confirmed by radioimmunoassay (Western blot). Of the AIDS patients sero-positive for HIV antibodies, 55% (6/11) were from the intravenous drug abuser group and 18% (2/11) from the homosexual group. A similar trend was seen in seropositive LAS patients, 85% (88/104) belonged to the drug abuser group and 6% (6/104) to the homosexual group. In seropositive asymptomatic subjects 83.7% (426/509) came from the drug abuser group and 4.9% (25/509) from the homosexual group. Thus drug abusers appear to be the major risk group in the Veneto region. They give rise to another risk group namely children born to seropositive drug abuser women. The seropositivity for HIV antibodies was low (0.02%) in subjects not in any risk group. Antibodies to HIV can be detected in amniotic, vitreous and cerebrospinal fluids as well as in sera.
A Service-Oriented Data Integration and Analysis Environment for In Silico Experiments and Bioinformatics Research (2007)

In this paper, we present a practical experiment of building a service-oriented system upon current Web services technologies and bioinformatics middleware. The system allows scientists to extract data from heterogeneous data sources and generate phylogenetic comparisons automatically. This can be difficult to accomplish using manual search tools since sequence data is rapidly accumulating. A Web-based environment enables scientists to more effectively define a task, perform the task at a desired time, monitor the execution status, and view the results. The first prototype of this system is being evaluated on a phylogenetic research application, Mother of Green (MoG). Our evaluation demonstrates that a service-oriented architecture can accelerate scientific research, increase research productivity, and provide a new approach to doing science. We also discuss issues in design and implementation of the system and identify our future research directions to enhance the system
Mitochondrial transmembrane ion distribution during anoxia (1987)

The distribution of pyruvate, phosphate, malate, citrate, K+, aspartate, glutamate, ADP, and ATP between the mitochondrial and cytosolic compartments was studied in isolated rat hepatocytes exposed to 30 min anoxia. The results show that pyruvate and citrate gradients are comparable to aerobic values, indicating that the pH gradient across the membrane under anaerobic conditions is comparable to that under normal aerobic conditions. In contrast, the distribution of phosphate, malate, ATP, ADP, aspartate, and glutamate suggests that transport of these species may be inhibited during anoxia. The results are discussed in terms of potential regulation of mitochondrial function to provide a quiescent anoxic state that is capable of recovering normal function on reoxygenation.

Influence of Blade Shape on Flow Performance and Noise Generation of Multi-Blade Blower (2011)

The influence of different parameters in the design of multi-blade fan , such as the ratio inner diameter of outer diameter, D1/D2 , number of blades, Z, inclination angle,α, outlet angle,βd2 , and inlet angle,βd1 , were examined in order to study relation between the flow pattern and noise level. In the present report, we investigated the fan performance and the noise characteristic experimentally and compared with simplified two-dimensional CFD analysis. The flow pattern passing the blades under the different geometrical conditions was examined and discussed in terms of fan performance and noise level. The results shows that high efficiency and low noise were attained in range of D1/D2=0.8-0.84 , Z=35-45 , α=30°-40°, and βd2=155°-165°. For these conditions, it was found that the pressure loss and noise generation in the flow between blades were attributed to the separation of the flow which was induced by the circulated vortex at the suction side, reattachment of the separated flow, and shear flow at the trailing edge. It was also confirmed that a large inner to outer diameter ratio gives a defected performance and big noise generation because of no reattachment of the separated flow. Also, the increasing of blade number resulted in the increasing of high frequency noise due to the vortices generation in shear layer in spite of rectification of passing flow.
