Rhythms in Cholesterol, Cholesteryl Esters, Free Fatty Acids, and Triglycerides in Blood of Lactating Dairy Cows (1990)

Blood samples from six lactating dairy cows were analyzed to determine whether circulating neutral lipids exhibit rhythmic variations. Plasma neutral lipids were measured by quantitative TLC on every fourth integrated 15-min blood sample taken over 48-h periods. Cows were housed in an environmental chamber at 20 degrees C with 16 h light:8 h dark (lights on at 0700 h), fed daily at 0900 h, and milked at 0830 and 2000 h. Other variables monitored included: body temperature, ammonia nitrogen, urea nitrogen, glucose, triiodothyronine, thyroxine, somatotropin, insulin, cortisol, and prolactin. Mean concentrations of cholesterol, cholesteryl esters, free fatty acids, and triglycerides were 21.4, 175.4, 3.1, and 6.3 mg/dl, respectively. Visual and power spectral analysis of the pulsatile fluctuations in lipids indicated rhythms with periods of 2 to 3 h. Amplitudes of rhythms for free fatty acids and triglycerides were 60% of mean concentrations and for cholesterol and cholesteryl esters were 20% of mean concentrations. The presence of these rhythms was conserved when data were averaged across time by cow. However, because of nonstationary conditions, rhythms identified by spectral analysis were not statistically significant. There was no evidence of circadian patterns in circulating neutral lipid components. All other metabolic and hormonal variables except cortisol exhibited distinct circadian rhythms.
Air Monitoring for Hazardous Gas Detection (2004)

The Hazardous Gas Detection Lab (HGDL) at Kennedy Space Center is involved in the design and development of instrumentation that can detect and quantify various hazardous gases. Traditionally these systems are designed for leak detection of the cryogenic gases used for the propulsion of the Shuttle and other vehicles. Mass spectrometers are the basis of these systems, which provide excellent quantitation, sensitivity, selectivity, response times and detection limits. A Table lists common gases monitored for aerospace applications. The first five gases, hydrogen, helium, nitrogen, oxygen, and argon are historically the focus of the HGDL.
Dual-functional polymeric waveguide with optical amplification and electro-optic modulation (1997)

Optical amplification and electro-optic modulation have been observed simultaneously in one polymeric material photo-lime gel which has been used as a volume holographic material to produce dichromated gelatin (DCG) films. In this paper, the dual functions were achieved by doping neodymium chloride hexahydrate (NdCl<SUB>3</SUB>(DOT)6H<SUB>2</SUB>O) and chlorophenol red (C<SUB>19</SUB>H<SUB>12</SUB>Cl<SUB>2</SUB>O<SUB>5</SUB>S). The optimized doping concentrations of Nd<SUP>+3</SUP> and chlorophenol red were 6.7 X 10<SUP>19</SUP>/cm<SUP>3</SUP> and 23% respectively. We observed a gain of 3.8 dB at 1.04 micrometers and an electro-optic coefficient of 30 pm/V at 633 nm. The experimental results confirms that the co-doping process does not degrade the respective functions of Nd<SUP>+3</SUP> for optical amplification and chlorophenol red for electro-optic modulation.
Role of 18F-FDG PET/CT in the Carcinoma of the Uterus: A Review of Literature (2014)

In the present review we reported the value of 18F-fluorodeoxyglucose (FDG) PET/CT in face of uterine cancer, in terms of sensitivity, specificity and accuracy. Moreover, we made a comparison with the other imaging techniques currently used to evacuate these tumors including contrast-enhanced CT, contrast enhanced-MRI and transvaginal ultrasonography. FDG PET/CT has been reported to be of particular value in detecting occult metastatic lesions, in prediction of response to treatment and as a prognostic factor.

Air-to-Fuel and Dual-Fuel Ratio Control of an Internal Combustion Engine (2009)

&lt;div class="htmlview paragraph"&gt;Air-to-fuel (A/F) ratio is the mass ratio of the air-to-fuel mixture trapped inside a cylinder before combustion begins, and it affects engine emissions, fuel economy, and other performances. Using an A/F ratio and dual-fuel ratio control oriented engine model, a multi-input-multi-output (MIMO) sliding mode control scheme is used to simultaneously control the mass flow rate of both port fuel injection (PFI) and direct injection (DI) systems. The control target is to regulate the A/F ratio at a desired level (e.g., at stoichiometric) and fuel ratio (ratio of PFI fueling vs. total fueling) to any desired level between zero and one. A MIMO sliding mode controller was designed with guaranteed stability to drive the system A/F and fuel ratios to the desired target under various air flow disturbances. The performance of the sliding mode controller was compared with a baseline multi-loop PID (Proportional-Integral-Derivative) controller through simulations and showed improvements over the baseline controller. Finally, the engine model and proposed sliding mode controller are implemented into a Hardware-In-the-Loop (HIL) simulator and a target engine control module, and HIL simulation is conducted to validate the developed controller for potential implementation in an automotive engine.&lt;/div&gt;
Electron Energy Loss Spectroscopy Investigation into Symmetry in Gold Trimer and Tetramer Plasmonic Nanoparticle Structures (2016)

We present a combined scanning transmission electron microscopy-electron energy loss spectroscopy (STEM-EELS) investigation into the mode symmetries of plasmonic nanoparticle trimer and tetramer structures. We obtain nanometer-resolved energy loss spectra for both trimer and tetramer structures and compare these to boundary element method simulations. We show that EELS, in conjunction with eigenmode simulations, offers a complete characterization of the individual superstructures, and we trace the evolution of both optically dark and bright modes and identify multipolar mode contributions. We then apply this technique to tetramer structures that exhibit an expanded range of mode symmetries for two-dimensional and three-dimensional self-assembled geometries. These findings provide a comprehensive experimental account of the available photonic states in self-assembled nanoparticle clusters.
The immune system in atherosclerosis and in acute myocardial infarction (2006)

Acute myocardial infarction (AMI) occurs when the atheromatous process prevents total blood flow through the coronary artery. It was previously thought that progressive luminal narrowing from the continued growth of smooth muscle cells (SMCs) in the plaque was the main cause of infarction, however, angiographic studies, have identified culprit lesions that do not cause marked stenosis. Is now evident that plaque activation, rather than stenosis, precipitates ischemia and infarction. Coronary spasm could be involved to some extent, but most cases of AMI are due to the formation of an occluding thrombus on the surface of the plaque; the two major causes of coronary thrombosis are plaque rupture and endothelial erosion. Plaque rupture is detectable in 60- 70% of cases and preferentially occurs when the fibrous cap is thin and partly destroyed. One of the major challenges in modern cardiology is the knowledge of the factors that induce a silent atherosclerotic plaque shifting from a stable to a vulnerable form.
Modified Hyper-Viscoelastic Constitutive Model for Elastomeric Materials (2018)

Elastomers constitute an essential group of materials that are widely used in the automotive, aerospace industry, biomedical, microfluidic and signal processing applications. Elastomeric materials undergo large deformations without fracture and exhibit time dependency under a prescribed displacement or load. Characterization of elastomeric materials can be challenging, hence the use of a proper constitutive model that captures the behavior of elastomeric materials is essential. Experimental data obtained from simple uniaxial tension tests and creep tests performed at various constant stress levels using dog bone samples were used to approximate hyperelasticity and the time-dependent responses of the material respectively. The experimental results suggested that the instantaneous strains were largely responsible for the nonlinear behavior of the material. Thus, a rheological hyper-viscoelastic constitutive model consisting of a nonlinear spring, which would capture the nonlinear instantaneous strains, and a two parameter Kelvin-Voight model, which would model the linear time-dependent strain responses, was developed. The Mooney-Rivlin model, a classic phenomenological hyperelastic model, was used to represent the nonlinear spring. The resulting hyper-visco constitutive model, which obeys the Boltzmann’s superposition principle, was used for numerical predictions of time-dependent behavior of this material in a commercial finite element software (Abaqus). The creep deformations predicted using this approach demonstrated good consistency with experimental results over the applied range of stresses and the duration of time measurements.
Quinacridone Solubility in Hot-Compressed Water (2007)

The solubility of quinacridone in hot-compressed water was measured for the first time at temperatures from (453.4 to 592.9) K and at a pressure of 24 MPa with a flow-type apparatus. The solubility varied from 1.07 × 10-5 mol·kg-1 at 453.4 K to 5.89 × 10-3 mol·kg-1 at 592.9 K. Dissolution equilibria of quinacridone were analyzed by a simple thermodynamic model on the basis of the measured solubility.
An estrogen sensor for poultry sex sorting1 (2010)

The need to segregate poultry based on sex is driven by sex-related differences in growth rate, market age, management practices, and nutritional requirements. Each day, poultry industry staff globally would ideally like to determine the sex of >150 million newly hatched birds. Currently, this can be done only manually at the hatchery, which is a virtually impossible undertaking. It is becoming more difficult each year to conduct manual sexing because this skill is disappearing from the workforce, is becoming unaffordable to the industry, and is encumbered by such negative effects as repetitive motion disorder. Automated sex sorting of eggs before hatching could resolve many, if not all, of these problems. We have developed a facile, rapid, and low-cost yeast-based assay that distinguishes male from female embryonated eggs before hatching based on the estrogen concentration of their allantoic fluid. Herein, we describe this novel sex-sorting technology, which we believe offers the potential to standardize and automate sex sorting in the poultry industry.
Model-Based Super-Resolution of SEM Images of Nano-Materials (2016)

measurements. The P&P super-resolution algorithm with LB-NLM as the prior produced the best quality interpolated images with the lowest mean squared error, visually accurate textures and edge-features, and no jaggies. Our results demonstrate that using an external library of high quality patches within the flexible P&P framework can improve super-resolution quality much beyond traditional model-based as well as linear interpolation methods.
Numbers of CD25+Foxp3+ T cells that lack the IL-7 receptor are increased intra-articularly and have impaired suppressive function in RA patients (2010)

These data demonstrate improved identification of FoxP3(+) T cells in RA patients by the absence of CD127 in addition to CD25 expression. Increased numbers of CD25(+)CD127(-) T cells are found in inflamed RA joints, but they have an impaired suppressive function, which could contribute to the persistent arthritis in these patients.

Development of magnetic separation system for thermal power plants (2020)

Assuming that the high‐gradient magnetic separation (HGMS) system based on a superconducting magnet can reduce iron oxide scale in boiler feedwater and contribute to the efficient operation of thermal power plants, we design a new matrix structure, which should efficiently capture iron oxide particles in boiler feedwater. We then evaluate their practicability experimentally and confirm that this HGMS system with the newly developed matrix is applicable to thermal power plants with the desired efficiency. On the bases of the results, we designed practical large‐scale HGMS systems for boiler feedwater with a superconducting magnet and new matrices, which has long cleaning cycles and low‐pressure loss. © 2020 Institute of Electrical Engineers of Japan.

The Hypertensive Effect of Amphotericin B-Containing Liposomes (Abelcet) in Mice: Dissecting the Roles of C3a and C5a Anaphylatoxins, Macrophages and Thromboxane (2022)

Liposomal amphotericin B (Abelcet) can cause infusion (anaphylactoid) reactions in patients whose mechanism is poorly understood. Here, we used mice to investigate the role of complement (C) receptors and the cellular sources of vasoactive mediators in these reactions. Anesthetized male NMRI and thromboxane prostanoid receptor (TP) or cyclooxygenase-1 (COX-1)-deficient and wild type C57Bl6/N mice were intravenously injected with Abelcet at 30 mg/kg. Mean arterial blood pressure (MABP) and heart rate (HR) were measured. In untreated mice, Abelcet caused a short (15 min) but large (30%) increase in MABP. C depletion with cobra venom factor (CVF) and inhibition of C5a receptors with DF2593A considerably prolonged, while C3aR inhibition with SB290157 significantly decreased the hypertensive effect. Likewise, the hypertensive response was abolished in COX-1- and TP-deficient mice. CVF caused a late hypertension in TP-deficient mice. Both macrophage depletion with liposomal clodronate and blockade of platelet GPIIb/IIIa receptors with eptifibatide prolonged the hypertensive effect. The early phase of the hypertensive effect is COX-1- and TP-receptor-dependent, partly mediated by C3aR. In contrast, the late phase is under the control of vasoactive mediators released from platelets and macrophages subsequent to complement activation and C5a binding to its receptor.
A New Route to the Phosphazene Polymerization Precursors, Cl<sub>3</sub>PNSiMe<sub>3</sub> and (NPCl<sub>2</sub>)<sub>3</sub> (1998)

An improved synthesis of the phosphazene polymerization precursors, hexachlorocyclotriphosphazene, (NPCl2)3 (1), and Cl3PNSiMe3 (2) is reported. The addition of PCl5 to N(SiMe3)3 in methylene chloride at 40 °C produced a mixture of phosphazenes which contained 76% of 1. However, the addition of N(SiMe3)3 to PCl5 in methylene chloride at 0 °C, followed by the addition of hexane, provided 2 in 40% yield. The mechanism of the reaction is discussed.
Development of a Disposable Magnetically Levitated Centrifugal Blood Pump (MedTech Dispo) Intended for Bridge‐to‐Bridge Applications—Two‐Week In Vivo Evaluation (2010)

Last year, we reported in vitro pump performance, low hemolytic characteristics, and initial in vivo evaluation of a disposable, magnetically levitated centrifugal blood pump, MedTech Dispo. As the first phase of the two-stage in vivo studies, in this study we have carried out a 2-week in vivo evaluation in calves. Male Holstein calves with body weight of 62.4–92.2 kg were used. Under general anesthesia, a left heart bypass with a MedTech Dispo pump was instituted between the left atrium and the descending aorta via left thoracotomy. Blood-contacting surface of the pump was coated with a 2-methacryloyloxyethyl phosphorylcholine polymer. Post-operatively, with activated clotting time controlled at 180–220 s using heparin and bypass flow rate maintained at 50 mL/kg/min, plasma-free hemoglobin (Hb), coagulation, and major organ functions were analyzed for evaluation of biocompatibility. The animals were electively sacrificed at the completion of the 2-week study to evaluate presence of thrombus inside the pump,together with an examination of major organs. To date, we have done 13 MedTech Dispo implantations, of which three went successfully for a 2-week duration. In these three cases, the pump produced a fairly constant flow of 50 mL/Kg/min. Neurological disorders and any symptoms of thromboembolism were not seen. Levels of plasma-free Hb were maintained very low. Major organ functions remained within normal ranges. Autopsy results revealed no thrombus formation inside the pump. In the last six cases, calves suffered from severe pneumonia and they were excluded from the analysis. The MedTech Dispo pump demonstrated sufficient pump performance and biocompatibility to meet requirements for 1-week circulatory support. The second phase (2-month in vivo study) is under way to prove the safety and efficacy of MedTech Dispo for 1-month applications.
Determination of efficacy of novel modified chitosan sponge dressing in a lethal arterial injury model in swine (2012)

Hm-chitosan is superior to unmodified chitosan sponges (p < 0.001) or standard gauze for controlling bleeding from a lethal arterial injury. The hm-chitosan technology may provide an advantage over native chitosan-based dressings for control of active hemorrhage.
Filtrage et filtres électriques - Avant-propos (2008)

Avec une grande quantité de filtres disponibles, le filtrage est l’une des fonctions les plus utilisées dans les systèmes électroniques. Qu’il soit d’affaiblissement ou correcteur de phase, le filtre possède une fonction assimilable à un traitement du signal, le signal utile est envoyé à travers un ensemble de circuits électroniques qui modifient son spectre de fréquence et/ou sa phase. Le but du filtrage est d’extraire une partie de l’information, afin de restituer un signal plus intelligible. Le filtre électrique vient lui modifier un signal électrique d’entrée, en un signal électrique de sortie. Cet article passe en revue et compare les différents types de filtre existant (numériques, analogiques, passifs, actifs à capacités commutées…), avec leurs réalisations et caractéristiques.

Supervised learning of classifiers via level set segmentation (2008)

A variational approach based on level set methods popular in image segmentation is presented for learning discriminative classifiers in general feature spaces. Nonlinear, nonparametric decision boundaries are obtained by minimizing an energy functional that incorporates a margin-based loss function. The class of level set contour decision boundaries is discussed in terms of the structural risk minimization principle. A variation on lscr <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> feature subset selection is developed. Use of level set classifiers as base learners for boosting is discussed.
Isolation and Identification of Cancer Stem-Like Cells in Adenocarcinoma and Squamous Cell Carcinoma of the Lung: A Pilot Study (2019)

<b>Background:</b> Lung cancer stem cells (CSCs) share many characteristics with normal stem cells, such as self-renewal and multipotentiality. High expression of aldehyde dehydrogenase (ALDH) has been detected in many tumors, particularly in the CSC compartment, and it plays an important role in tumor proliferation, metastasis, and drug resistance. CD44 is commonly used as a cell surface marker of cancer stem-like cells in epithelial tumors. The aim of this study was to isolate and analyze cancer stem-like cells from surgically removed specimens to compare lung adenocarcinoma (ADENO) and squamous (SQUAMO) cell carcinoma. <b>Methods:</b> The ALDEFLUOR assay was used to identify and sort ALDH<sup>high</sup> and ALDH<sup>low</sup> human lung cancer cells following tissue digestion. Fluorescence-activated cell sorting analysis for CD44 was performed with tumor cells. Quantitative real-time PCR was performed to assess the expression of SOX2 and NANOG as stemness markers. ALDH1A1 expression was additionally determined by immunohistochemistry. Anchorage-independent ALDH<sup>high</sup> cell growth was also evaluated. ALDH<sup>high</sup> ADENO and SQUAMO cells were cultured to analyze spheroid formation. <b>Results:</b> All specimens contained 0.5-12.5% ALDH<sup>high</sup> cells with 3.8-18.9% CD44-positive cells. SOX2 and NANOG relative expression in ALDH<sup>high</sup> compared to ALDH<sup>low</sup> cells in ADENO and SQUAMO was analyzed and compared between the histotypes. Immunohistochemistry confirmed the presence of ALDH1A1 in the sections. SOX2 and NANOG were expressed at higher levels in the ALDH<sup>high</sup> subpopulation than in the ALDH<sup>low</sup> subpopulation only in ADENO cells, and the opposite result was seen in SQUAMO cells. <i>In vitro</i> functional assays demonstrated that ALDH<sup>high</sup> cells exhibited migration capacity with distinct behaviors between ALDH<sup>high</sup> spheres in ADENO vs. SQUAMO samples. <b>Conclusions:</b> Our results highlight the importance of a better characterization of cancer stem-like cells in ADENO and SQUAMO histotypes. This may suggest new differential approaches for prognostic and therapeutic purposes in patients with non-small-cell lung cancer.
