Predictors of long-term outcome of functional dyspepsia and duodenal ulcer after successful Helicobacter pylori eradication – a 7-year follow-up study (2009)

In clinical practice, long-term symptomatic benefit, in duodenal ulcer patients, after H. pylori eradication, is similar to that in patients with functional dyspepsia. Early evaluation of symptoms after successful H. pylori eradication may be predictive of outcome in dyspeptic patients. Most symptomatic patients did not seek antidyspeptic drugs. Use of antisecretory medications was, however, greater in patients with functional dyspepsia than in duodenal ulcer patients.
Experimental Study of Paraffin Deposition Under Two-Phase Gas/Oil Slug Flow in Horizontal Pipes (2016)

Summary Paraffin or wax deposition under two-phase gas/oil slug flow in horizontal pipes is studied experimentally. The experiments are conducted by use of a 2.067-in., large-scale multiphase flow loop under an operating pressure of 350 psig. Testing fluids are Garden Banks condensate and natural gas. Two-phase-flow hydrodynamics and single-phase paraffin-deposition experiments are conducted and used as base cases for a comprehensive data analysis. Deposition experiments are conducted with parametric variation of oil and gas superficial velocities and testing durations of 4, 12, and 24 hours. The bulk fluid and initial pipe-wall temperatures at a removable spool piece are kept below wax-appearance temperature (WAT) and relatively constant to ensure consistent initial dissolved-wax-concentration differences and to avoid thermal restriction in the growth of the deposit. Unprecedented detailed measurement and analysis of the circumferential local samples are conducted by use of a newly designed pigging tool with high-temperature-gas-chromatography (HTGC) and differential-scanning-calorimetry (DSC) deposit-characterization techniques. The results reveal that deposit thickness decreases with the increase in the superficial liquid velocity (vSL) for all two-phase-flow cases. The crossover trends of the thickness vs. time are suggested by the single-phase deposition data to occur at times less than 6 hours. Circumferential analysis shows that, for the slug-flow wax deposit, the deposit at the top wall is thicker (by a factor of approximately 1.9), softer, and contains more oil than the bottom deposit. The final overall deposit wax contents are found to increase with the superficial gas velocity (vSG) for the case of vSL = 1 ft/sec, but nonmonotonic change occurs for the case of vSL = 3 ft/sec. Wax deposits under slug flow have longer chain n-alkane compared with single-phase flow having the same wax-fraction cases. Wax mass at the top wall is greater (by a factor of approximately 1.7) than the bottom mass. This new set of complete experimental data serves as the fundamental understanding of single-phase and two-phase gas/oil slug-flow paraffin deposition.
Scaling of 6n-Fold Bond-Orientational Order Parameters in a Hexatic Liquid-Crystal Thin Film (1996)

Electron-diffraction measurements have been conducted on two-layer free-standing films of $n$-pentyl- ${4}^{\ensuremath{'}}$- $n$-pentanoyloxy-biphenyl-4-carboxylate (54COOBC). This compound undergoes the smectic- $A$--hexatic- $B$--crystal- $B$ phase sequence, but its thin films exhibit power-law thermal anomalies at the smectic- $A$--hexatic- $B$ transition which are not predicted in the theory of defect-mediated melting in two dimensions. The films just below the transition show hexaticlike positional correlations but no equilibrium bond-orientational order. The $6n$-fold bond-orientational order parameters ${C}_{6n}$, which can be determined at lower temperatures, are consistent with the scaling relation ${C}_{6n}{\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}C}_{6}^{\ensuremath{\sigma}(n)}$, where $\ensuremath{\sigma}(n){\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}n}^{2}$, as expected in a two-dimensional $\mathrm{XY}$ system.
Multiwavelength self-pulsating fibre laser based on cascaded SPM spectral broadening and filtering (2008)

We experimentally demonstrate the operation of a laser based on self-phase modulation followed by offset spectral filtering. This laser has three operation modes: a continuous-wave mode, a self-pulsating mode where the laser self ignites and produces pulses, and a pulse-buffering mode where no new pulse is formed from spontaneous emission noise but only pulses already propagating or pulses injected in the laser cavity can be sustained. In the self-pulsating and pulse-buffering modes, the laser is multi-wavelength and continuously tunable over the entire gain band of the amplifiers. The output pulse width is quasi transform-limited with respect to the spectral-width of the filters used in the cavity. Overall, this device provides a simple alternative to pulsed laser source and also represents a promising approach for signal buffering.
Phytochemical analysis and evaluation of antioxidant and photoprotective activities of extracts from flowers ofBromelia laciniosa(Bromeliaceae) (2017)

In this study, the phytochemical profile of extracts from the flowers of Bromelia laciniosa was characterized. The total phenolic and flavonoids contents were determined and the antioxidant and photoprotective activities were evaluated using in vitro assays. Phytochemical analysis demonstrated that the extracts were found to be positive for the presence of anthracene derivatives, anthraquinones, coumarins, flavonoids and tannins, lignans, mono and diterpenes. The ethanol extract (Bl-EtOH) presented the most significant total phenolic content (53.75 ± 1.25 mg GAE/g). The dichloromethane extract (Bl-CH2Cl2) showed the highest flavonoid content (46.06 ± 1.18 mg CE/g). The methanol extract (Bl-MeOH) was the most effective extract in the DPPH (2,2-diphenyl-1-picrylhydrazil) assay (EC50 141.90 ± 3.01 μg/mL). Bl-EtOH and Bl-MeOH showed higher sun protection factor at a concentration of 100 mg/L (3.38 ± 0.04 and 3.78 ± 0.11, respectively). Therefore, the extracts proved to be interesting for the development of new studies aiming their incorporation into photoprotective cosmetic formulations.
An Integral Method for Determining Induced Voltage in Time-Varying Wire Inductors (2005)

This report documents the creation of software tools to model time-varying wire inductors. The class of inductors studied consists of arbitrary wire shapes in nonmagnetic material. When the wire structures are deformed, the inductance changes, and a voltage is induced. This voltage is of interest, for instance when the inductor is used to measure or sense a shockwave. An integral technique, which only requires integrating over the wire segments, is used to find the inductance at each time step, with backwards-difference approximations being used on successive time steps to determine the voltage. This method allows for arbitrary time-varying wire structures. It was tested for several canonical problems and used to model a double helix solenoid compressed by a shockwave.
Early fibroproliferative signs on high-resolution CT are associated with mortality in COVID-19 pneumonia patients with ARDS: a retrospective study (2021)

Early pulmonary fibroproliferative signs on HRCT are associated with increased mortality and susceptibility to organ injury in COVID-19 pneumonia patients with early ARDS.
Absolute Viscosities of Vegetable Oils at Different Temperatures and Shear Rate Range of 64.5 to 4835 s−1 (2014)

A study was carried out to determine the effect of higher shear rates (64.5 to 4835 s −1 ) on the absolute viscosities of different vegetable oils at different temperatures (26 to 90°C). The absolute viscosities of the different vegetable oils were determined using a Lamy Viscometer RM100, a rotating viscometer with coaxial cylinder. The torque of each sample at different temperatures was recorded at different shear rates. Based on the rheograms (plot of mean shear stress against shear rate), all of the vegetable oils studied were found to be Newtonian fluids. Rice bran oil was the most viscous (0.0398 Pa·s at 38°C) while walnut oil was the least viscous (0.0296 Pa·s at 38°C) among the oils studied. The higher shear range used did not significantly affect the absolute viscosities of the vegetable oils at the different temperatures. The absolute viscosities of the vegetable oils decreased with increasing temperature and can be fitted with an Arrhenius type relationship. The activation energies for the different vegetable oils ranged from 21 to 30 kJ/mole. The peanut and safflower oils had the highest and lowest activation energies, respectively. This means that greater energy was needed to effect a viscosity change in the peanut oil.
In vitroandin vivometabolism of CHF 6001, a selective phosphodiesterase (PDE4) inhibitor (2015)

1. The metabolism of CHF 6001, a novel PDE4 inhibitor, was determined in vitro in mouse, rat, dog, monkey and human microsomes and hepatocytes and in vivo in plasma, urine, feces and bile of rats after intravenous and intratracheal administration. 2. The behavior of CHF 6001 in microsomes and hepatocytes changed across species. CYP3A4/5 isoenzymes were identified to be the primary enzymes responsible for the metabolism of CHF 6001 in human liver microsomes. 3. In the rat, CHF 6001 was found extensively metabolized in urine, feces and bile, but not in plasma, where CHF 6001 was the main compound present. The metabolite profiles were different in the four biological matrices from both qualitative and quantitative point of view. 4. CHF 6001 was metabolized through hydrolysis with the formation of the alcohol CHF 5956, loss of a chlorine atom, loss of the N-oxide, hydroxylation, loss of the cyclopropylmethyl group in the alcohol moiety, conjugation with glucuronic acid, glutathione and cysteine-glycine. 5. The major metabolite present in the bile was isolated and characterized by nuclear magnetic resonance analysis. It derived from CHF 6001 through contraction of the pyridine-N-oxide ring to N-hydroxy pyrrole and conjugation with glucuronic acid.

Temperature Dependence of Elastic Constant Measurements on Thin Films by Picosecond Ultrasonics (2008)

The temperature dependence of mechanical parameters is well-known for bulk materials. New methods have to be developed to access such characteristics on thin films. These measurements are needed for understanding the temperature behavior of acoustic components in microelectronics, as for Bulk Acoustic Wave (BAW) resonators used in wireless communication. A BAW resonator uses the thickness mode resonance of a piezoelectric layer (Aluminium Nitride). In the radio-frequency range, a BAW resonator is a complex stack of various materials in thin film. The temperature dependences measurements offer a way to regulate the performances' drift induced by the warming of the device and to design temperature-independent components. Here, we present a method based on a variable temperature picosecond ultrasonics setup. The procedure is first validated on silica, then applied on various BAW technology materials (AlN, Mo, SiN, W).
Multilevel Strip Pooling-Based Convolutional Neural Network for the Classification of Carotid Plaque Echogenicity (2021)

Carotid plaque echogenicity in ultrasound images has been found to be closely correlated with the risk of stroke in atherosclerotic patients. The automatic and accurate classification of carotid plaque echogenicity is of great significance for clinically estimating the stability of carotid plaques and predicting cardiovascular events. Existing convolutional neural networks (CNNs) can provide an automatic carotid plaque echogenicity classification; however, they require a fixed-size input image, while the carotid plaques are of varying sizes. Although cropping and scaling the input carotid plaque images is promising, it will cause content loss or distortion and hence reduce the classification accuracy. In this study, we redesign the spatial pyramid pooling (SPP) and propose multilevel strip pooling (MSP) for the automatic and accurate classification of carotid plaque echogenicity in the longitudinal section. The proposed MSP module can accept arbitrarily sized carotid plaques as input and capture a long-range informative context to improve the accuracy of classification. In our experiments, we implement an MSP-based CNN by using the visual geometry group (VGG) network as the backbone. A total of 1463 carotid plaques (335 echo-rich plaques, 405 intermediate plaques, and 723 echolucent plaques) were collected from Zhongnan Hospital of Wuhan University. The 5-fold cross-validation results show that the proposed MSP-based VGGNet achieves a sensitivity of 92.1%, specificity of 95.6%, accuracy of 92.1%, and F1-score of 92.1%. These results demonstrate that our approach provides a way to enhance the applicability of CNN by enabling the acceptance of arbitrary input sizes and improving the classification accuracy of carotid plaque echogenicity, which has a great potential for an efficient and objective risk assessment of carotid plaques in the clinic.
Assessment of insulin action and glucose effectiveness in diabetic and nondiabetic humans. (1994)

Insulin concentrations in humans continuously change and typically increase only when glucose also increases such as with eating. In this setting, it is not known whether the severity of hepatic and extrahepatic insulin resistance is comparable and whether the ability of glucose to regulate its own uptake and release is defective in non-insulin-dependent diabetes mellitus (NIDDM). To address this question, NIDDM and nondiabetic subjects were studied when glucose concentrations were clamped at either 5 mM (euglycemia) or varied so as to mimic the glucose concentrations observed in nondiabetic humans after food ingestion (hyperglycemia). Insulin was infused so as to simulate a "nondiabetic" postprandial profile. During euglycemia, insulin increased glucose disposal in nondiabetic but not diabetic subjects indicating marked extrahepatic resistance. In contrast, insulin-induced suppression of glucose release was only minimally less (P < 0.05) in diabetic than nondiabetic subjects (-1.06 +/- 0.09 vs. -1.47 +/- 0.21 nmol.kg-1 per 4 h). Hyperglycemia substantially enhanced disposal in both groups. Glucose effectiveness measured as the magnitude of enhancement of disposal (0.59 +/- 0.18 vs. 0.62 +/- 0.17 nmollkg-1 per 4 h) and suppression of release (-0.36 +/- 0.12 vs. -0.14 +/- 0.12 nmol.kg-1 per 4 h) did not differ in the diabetic and nondiabetic subjects. In conclusion, when assessed in the presence of a physiological insulin profile, people with NIDDM demonstrate: (a) profound extrahepatic insulin resistance, (b) modest hepatic insulin resistance, and (c) normal ability of glucose to stimulate its own uptake and suppress its own release.
Bounds for Random Constraint Satisfaction Problems via Spatial Coupling (2015)

We report on a novel technique called spatial coupling and its application in the analysis of random constraint satisfaction problems (CSP). Spatial coupling was invented as an engineering construction in the area of error correcting codes where it has resulted in efficient capacity-achieving codes for a wide range of channels. However, this technique is not limited to problems in communications, and can be applied in the much broader context of graphical models. We describe here a general methodology for applying spatial coupling to random constraint satisfaction problems and obtain lower bounds for their (rough) satisfiability threshold. The main idea is to construct a distribution of geometrically structured random K-SAT instances – namely the spatially coupled ensemble – which has the same (rough) satisfiability threshold, and is at the same time algorithmically easier to solve. Then by running well-known algorithms on the spatially coupled ensemble we obtain a lower bound on the (rough) satisfiability threshold of the original ensemble. The method is versatile because one can choose the CSP, there is a certain amount of freedom in the construction of the spatially coupled ensemble, and also in the choice of the algorithm. In this work we focus on random K-SAT but we have also checked that the method is successful for Coloring, NAE-SAT and XOR-SAT. We choose Unit Clause propagation for the algorithm which is analyzed over the spatially coupled instances. For K = 3, for instance, our lower bound is equal to 3.67 which is better than the current bounds in the literature. Similarly, for graph 3-colorability we get a bound of 2.22 which is also better than the current bounds in the literature.
Deep-Tow Observations at the East Pacific Rise, 8°45'N, and Some Interpretations (1980)

A near-bottom survey of a 24-km length of the East Pacific Rise (EPR) crest near the Leg 54 drill sites has established that the axial ridge is a 12-to 15-km-wide lava plateau, bounded by steep 300-meter-high slopes that in places are large outward-facing fault scarps. The plateau is bisected asymmetrically by a 1-to 2-km-wide crestal rift zone, with summit grabens, pillow walls, and axial peaks, which is the locus of dike injection and fissure eruption. About 900 sets of bottom photos of this rift zone and adjacent parts of the plateau show that the upper oceanic crust is composed of several different types of pillow and sheet lava. Sheet lava is more abundant at this rise crest than on slow-spreading ridges or on some other fastspreading rises. Beyond 2 km from the axis, most of the plateau has a patchy veneer of sediment, and its surface is increasingly broken by extensional faults and fissures. At the plateau's margins, secondary volcanism builds subcircular peaks and partly buries the fault scarps formed on the plateau and at its boundaries. Another deep-tow survey of a patch of young abyssal hills 20 to 30 km east of the spreading axis mapped a highly lineated terrain of inactive horsts and grabens. They were created by extension on inward-and outwardfacing normal faults, in a zone 12 to 20 km from the axis. Sediments sampled on the rise crest and flanks are mixtures of calcareous ooze and metalliferous precipitates, and they have been redistributed by southerly currents with average velocities of 9 cm/s.
Extended Medial Gastrocnemius Rotational Flap for Treatment of Chronic Knee Extensor Mechanism Deficiency in Patients with and without Total Knee Arthroplasty (2004)

Nine patients with chronic extensor mechanism disruption were treated with an extended medial gastrocnemius rotational flap reconstruction of the extensor mechanism. Seven patients previously had total knee arthroplasty and two patients had chronic infection of nonreplaced, native knees. Four patients previously had failed Achilles' tendon allograft reconstruction after total knee arthroplasty and two were complicated by infection. Infected arthroplasty patients had a staged procedure with placement of an antibiotic spacer after debridement and extended medial gastrocnemius rotational flap, followed by total knee arthroplasty replant 8 weeks later. The four infected arthroplasty patients had medical comorbidities that included a patient with HIV and hemophilia, and two with diabetes mellitus. Another patient with rheumatoid arthritis was severely malnourished as a result of dumping syndrome. Of the four patients treated by this two-stage procedure, one died in the early postoperative period from chronic medical issues after the second stage and another patient elected to have above-knee amputation after the first stage because of severe reflex sympathetic dystrophy. The final group of seven patients was studied at a mean followup of 21 months (range, 7-31 months), the average extensor lag was 13.5 degrees (range, 0-50 degrees ), and the average range of motion was 2 degrees to 93 degrees . The two patients with nonreplaced, native knees had extensor lags of 30 degrees and 10 degrees . All patients were able to regain sufficient extensor mechanism strength to return to independent ambulation, and all infections resolved after treatment. Two patients were able to ascend stairs foot over foot without support. In addition to the patient who had amputation, the other complication involved a wound breakdown that required a free flap at 13 months in a patient who had a failed Achilles' tendon allograft reconstruction after takedown of a knee fusion. Medial gastrocnemius flap reconstruction can provide successful salvage of a failed extensor mechanism allograft or an alternative to allograft reconstruction in patients with poor soft tissue coverage, previous infection, or a compromised immune system.

Fill the Bench and Empty the Docket: Filibuster Reform for District Court Nominations (2012)

Judges are, without question, vital to our justice system. They interpret, adapt, and apply the law. They resolve disputes for the parties to the case at issue and provide guidance to others in analogous situations. They are the gears that keep the wheels of justice moving. Unfortunately, in the case of our federal courts, many of these gears are missing. Eighty-three of our 874 federal judgeships are vacant, including thirty-four that have been declared “judicial emergencies.” Our Constitution vests the President with the power to nominate federal judges and the Senate with the power to confirm or reject them, and Senate rules give the Judiciary Committee the power to hold hearings on each judicial nominee. Additionally, every individual senator has the ability to extend debate indefinitely (also known as the filibuster). As anybody who follows politics knows, this can lead to contentious debates and lengthy confirmation processes that keep getting lengthier.
Impedance Modeling of Solid-State Electrolytes: Influence of the Contacted Space Charge Layer (2021)

Understanding the interfacial impedance between the solid electrolyte and the electrode is a critical issue for the design of solid-state batteries. We propose a new equivalent circuit model that treats the interface not only as a capacitor but also includes the space charge layer resistance and the resultant polarization resistance. Moreover, the elements of the circuit model are quantified by the physical quantities based on the recently proposed modified Planck-Nernst-Poisson (MPNP) model, which includes the effect of the unoccupied regular lattice sites (vacancies) in the electro-diffusion problem and takes both the ion and electron contributions into the account. We provide a new analytical solution for the space charge layer capacitance. Comparative numerical results demonstrate that our proposed model with additional polarization resistance can explain well the real impedance tail at the low-frequency region, for which the pure capacitor interface model fails. The model is verified against the experimental impedance spectra of LiPON.
High-Risk Human Papillomavirus and Cervical Intraepithelial Neoplasia at Time of Atypical Squamous Cells of Undetermined Significance Cytologic Results in a Population with Human Immunodeficiency Virus (2004)

Despite a high rate of HPV infection in the HIV population with ASCUS Pap results, high-risk HPV subtypes represent a minority of patients and are significantly associated with presence of high-grade CIN at colposcopy. High-risk HPV testing should be investigated further in the HIV population.
