Benefits of Heated and Humidified High Flow Nasal Oxygen for Preoxygenation in Morbidly Obese Patients Undergoing Bariatric Surgery: A Randomized Controlled Study (2014)

Background: Due to loss of functional residual capacity, morbidly obese patients are threatened by hypoxemia during anesthesia induction. To prevent hypoxemia, optimal preoxygenation is mandatory for safe anesthesia induction in morbidly obese patients.
Brazilian Green Propolis on <i>Helicobacter pylori</i> Infection. A Pilot Clinical Study (2007)

Brazilian green propolis used in popular dose showed minimal effect on H. pylori infection. Larger studies with longer duration, larger dose, and different frequency of administration of propolis extract should be undertaken to define its role on H. pylori therapy.

SkinProf: An Android Application for Smart Cosmetic and Skincare Users (2018)

The number of smartphone users increases continuously since the smartphone enables people to access data from anywhere and at any time. However, data accessibility for cosmetic and skincare products to check safety, information, and allergies of each cosmetic ingredient is quite difficult. Many people hesitate to try new products or new brands as they have no knowledge of cosmetic ingredients, the chemical characteristics of each ingredient, and quality. Moreover, they may be unsure that the product is appropriate for their skin. Therefore, to alleviate these problems, this research project proposes SkinProf, which is an Android application for providing knowledge about cosmetic and skin care products to smart consumers. SkinProf will help cosmetic users have convenient access to check the safety level of each ingredient and realize which ingredient they should avoid. SkinProf allows them to compare the ingredients between products and select the most appropriate product.
Towards better integrators for dissipative particle dynamics simulations (2000)

Coarse-grained models that preserve hydrodynamics provide a natural approach to study collective properties of soft-matter systems. Here, we demonstrate that commonly used integration schemes in dissipative particle dynamics give rise to pronounced artifacts in physical quantities such as the compressibility and the diffusion coefficient. We assess the quality of these integration schemes, including variants based on a recently suggested self-consistent approach, and examine their relative performance. Implications of integrator-induced effects are discussed.
Fuzzy logic based flight control system for hypersonic transporter (2002)

A fuzzy logic based flight control system for a hypersonic transporter is proposed, in order to provide the longitudinal stability in the hypersonic region and to improve the response of the vehicle as well as to make the response exactly follow the commands. The construction of the fuzzy logic controller is set up, in which angle of attack and pitch rate are chosen as input linguistic variables, and the deflection of the elevator is the control variable. Fourteen fuzzy inference rules, which are designed to model a human operator's behaviour, are employed, and the fuzzy algorithm of maxmin composition is used as an inference mechanism. Performance evaluation of the fuzzy logic controller for the hypersonic transporter is carried out at four flight points, which are chosen from the whole flight envelope. The calculation results show that the fuzzy logic controller has a good ability to stabilize the vehicle in the hypersonic region, and is fairly robust across the flight envelope.
Improved metastatic animal model of human prostate carcinoma using surgical orthotopic implantation (SOI). (2000)

SOI is good technique to establish the efficiently metastatic animal mode. SOI using PC-3M human prostate cell line will leads to 100% metastasis of prostate tumor cells. So far, this model is much quicker and more efficient than those reported in literatures.
Measurement of subnanosecond anisotropy decays of protein fluorescence using frequency-domain fluorometry. (1986)

We report the first anisotropy decays of protein fluorescence obtained using a frequency-domain fluorometer. The ultraviolet light source (300 nm) was a ring dye laser equipped with an intracavity frequency doubler, pumped by an argon ion laser. The data, measured at modulation frequencies from 2 to 200 MHz, reveal the presence of subnanosecond motions (0.1-0.2 ns) of the single tryptophan residues in melittin and monellin. For melittin the data also indicate the presence of slower motions near 1 ns, which may be the result of concerted motions of several peptide units. Smaller amplitude motions, on a similar timescale, were observed for the single tryptophan residue in staphylococcal nuclease. We demonstrate using N-acetyl-L-tryptophanamide in water that the method of frequency-domain fluorometry is capable of measuring correlation times as short as 50 ps. This method can provide data for the direct comparison of measured anisotropy decays with those predicted from molecular dynamics calculations.
Decreased phosphoribosylpyrophosphate as the basis for decreased purine synthesis during amino acid starvation of human lymphoblasts. (1984)

Rates of de novo and salvage purine synthesis decrease by approximately 80 and 60%, respectively, when normal human lymphoblasts are starved 3 h for an essential amino acid (Boss, G. R., and Erbe, R. W. (1982) J. Biol. Chem. 257, 4242-4247). Amino acid starvation decreased the intracellular phosphoribosylpyrophosphate (PP-Rib-P) and ribose 5-phosphate concentrations by approximately 40%, but neither the specific activities of PP-Rib-P synthetase and glutamine amidophosphoribosyltransferase nor the intracellular concentrations of purine nucleotides and inorganic phosphate changed significantly. In mutant cells with either an increased capacity to generate PP-Rib-P (superactive PP-Rib-P synthetase), or an increased PP-Rib-P concentration (inosinate-guanylate:pyrophosphate phosphoribosyltransferase deficiency), the intracellular PP-Rib-P concentration decreased by less than 15% during amino acid starvation and de novo purine synthesis decreased significantly less than in normal cells. When normal cells were treated with drugs that simultaneously decreased feed-back inhibition by purine nucleotides and increased the intracellular concentration of ribose 5-phosphate and PP-Rib-P rates of de novo purine synthesis were stimulated 3-fold in nonstarved cells and more than 8-fold in starved cells. This greater stimulation in the starved cells appeared to be from the increased PP-Rib-P production; moreover, in starved cells in which the increase of the PP-Rib-P concentration by the drugs was impaired because of purine nucleoside phosphorylase deficiency, rates of de novo purine synthesis increased only 3.5-fold. The data suggest that amino acid starvation decreases purine synthesis by decreasing the generation of PP-Rib-P from glucose.

Performance prediction using spatial autocorrelation (2007)

Evaluation of information retrieval systems is one of the core tasks in information retrieval. Problems include the inability to exhaustively label all documents for a topic, generalizability from a small number of topics, and incorporating the variability of retrieval systems. Previous work addresses the evaluation of systems, the ranking of queries by difficulty, and the ranking of individual retrievals by performance. Approaches exist for the case of few and even no relevance judgments. Our focus is on zero-judgment performance prediction of individual retrievals. One common shortcoming of previous techniques is the assumption of uncorrelated document scores and judgments. If documents are embedded in a high-dimensional space (as they often are), we can apply techniques from spatial data analysis to detect correlations between document scores. We find that the low correlation between scores of topically close documents often implies a poor retrieval performance. When compared to a state of the art baseline, we demonstrate that the spatial analysis of retrieval scores provides significantly better prediction performance. These new predictors can also be incorporated with classic predictors to improve performance further. We also describe the first large-scale experiment to evaluate zero-judgment performance prediction for a massive number of retrieval systems over a variety collections in several languages.
Finite-State Chart Constraints for Reduced Complexity Context-Free Parsing Pipelines (2012)

We present methods for reducing the worst-case and typical-case complexity of a context-free parsing pipeline via hard constraints derived from finite-state pre-processing. We perform O(n) predictions to determine if each word in the input sentence may begin or end a multi-word constituent in chart cells spanning two or more words, or allow single-word constituents in chart cells spanning the word itself. These pre-processing constraints prune the search space for any chart-based parsing algorithm and significantly decrease decoding time. In many cases cell population is reduced to zero, which we term chart cell “closing.” We present methods for closing a sufficient number of chart cells to ensure provably quadratic or even linear worst-case complexity of context-free inference. In addition, we apply high precision constraints to achieve large typical-case speedups and combine both high precision and worst-case bound constraints to achieve superior performance on both short and long strings. These bounds on processing are achieved without reducing the parsing accuracy, and in some cases accuracy improves. We demonstrate that our method generalizes across multiple grammars and is complementary to other pruning techniques by presenting empirical results for both exact and approximate inference using the exhaustive CKY algorithm, the Charniak parser, and the Berkeley parser. We also report results parsing Chinese, where we achieve the best reported results for an individual model on the commonly reported data set.
Pathogenesis of chronic inflammatory demyelinating polyradiculoneuropathy (2006)

The acute lesions of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) consist of endoneurial foci of chemokine and chemokine receptor expression and T cell and macrophage activation. The myelin protein antigens, P2, P0, and PMP22, each induce experimental autoimmune neuritis in rodent models and might be autoantigens in CIDP. The strongest evidence incriminates P0, to which antibodies have been found in 20% of cases. Failure of regulatory T-cell mechanism is thought to underlie persistent or recurrent disease, differentiating CIDP from the acute inflammatory demyelinating polyradiculoneuropathy form of Guillain-Barré syndrome. Corticosteroids, intravenous immunoglobulin and plasma exchange each provide short term benefit but the possible long-term benefits of immunosuppressive drugs have yet to be confirmed in randomised, controlled trials.
Isolectin composition of individual clones of <i>Urtica dioica:</i> Evidence for phenotypic differences (1987)

Analysis of the isolectin composition of 102 individual nettle ( Urtica dioica L.) clones by ion‐exchange chromatography revealed the occurrence of at least 11 different isolectins, which all had the same molecular structure and exhibited identical carbohydrate‐binding specificity and agglutination properties. All 11 isolectins, however, did not occur simultaneously; 34 combinations of either 1, 2, 3, 4 or 5 isolectins were found. Since the occurrence of multiple molecular forms of the nettle agglutinin cannot be explained by the (partial) autotetraploid character of stinging nettle it is postulated to rely on the expression of a family of closely related lectin genes.
Design, fabrication, and analysis of SiGeC heterojunction PMOSFETs (2000)

We present the evaluation of the strain-stabilizing capabilities of C in the Si/sub 1-x/Ge/sub x/ system. To demonstrate these effects, we have designed Si/sub 1-x-y/Ge/sub x/C/sub y/ heterojunction PMOSFET devices over a range of Ge concentrations, with thicknesses that would typically result in related or metastable films under normal processing conditions. The dc characteristics of Si/sub 1-x-y/Ge/sub x/C/sub y/, SiCe, and Si PMOSFETs (L=10 /spl mu/m) were evaluated at room temperature and at 77 K. In general, the saturation mobility in Si/sub 1-x-y/Ge/sub x/C/sub y/ devices is higher than that of Si/sub 1-x/Ge/sub x/ and Si devices at low gate bias and room temperature. This enhancement is attributed to the strain stabilization effect of C. With proper optimization of Ge and C concentrations, it is possible to fabricate devices with significant improvements in drive current under normal operating conditions (0-3 V, 300 K). This application of Si/sub 1-x-y/Ge/sub x/C/sub y/ in PMOSFETs demonstrates the potential benefits of using of C in the Column IV heterostructure system.
A Technology of Microwave Direction Finding with Circular Array Combination Method (2005)

This paper describes a microwave direction finding technology which is used for RF signal acquisition and monitoring systems. This paper suggests a direction finding method which use a combination of the amplitude-comparison technology and the phase-comparison technology. The amplitude-comparison technology uses the amplitude difference of the RF signals received from the array antennas of direction finding system and removes the ambiguity of wave incident bearing. The phase-comparison technology uses the phase difference of the RF signals received from the same nay antennas and makes a good direction finding accuracy. The suggested direction finding technology is designed to place 8 array antennas in a distance around the circle for azimuth angle. Also it is designed to use the phase difference of the received signals ken two nearby antennas to measure the signal incident direction accurately and to use the amplitude difference to remove the ambiguity of wave incident bearing. The simulation and measurement results are under bearing error in GHz when SNR is 30 dB.
Safe Structural Conformance for Java (2000)

In Java, an interface specifies public abstract methods and associated public constants. Conformance of a class to an interface is by name. We propose to allow structural conformance to interfaces: any class or interface that declares or implements each method in a target interface conforms structurally to the interface, and any expression of the source class or interface type can be used where a value of the target interface type is expected. We argue that structural conformance results in a major gain in flexibility in situations that require retroactive abstraction over types. Structural conformance requires no additional syntax and only small modifications to the Java compiler and optionally, for performance reasons, the virtual machine, resulting in a minor performance penalty. Our extension is type-safe: a cast-free program that compiles without errors will not have any type errors at run time. Our extension is conservative: existing Java programs still compile and run in the same manner as under the original language definition. Finally, structural conformance works well with recent extensions such as Java remote method invocation. We have implemented our extension of Java with structural interface conformance by modifying the Java Developers Kit 1.1.5 source release for Solaris and Windows 95/NT. We have also created a test suite for the extension.
Poly(amide-imide)/Silica Supported PEI Hollow Fiber Sorbents for Postcombustion CO<sub>2</sub> Capture by RTSA (2014)

Amine-loaded poly(amide-imide) (PAI)/silica hollow fiber sorbents are created and used in a rapid temperature swing adsorption (RTSA) system for CO2 capture under simulated postcombustion flue gas conditions. Poly(ethylenimine) (PEI) is infused into the PAI/mesoporous silica hollow fiber sorbents during fiber solvent exchange steps after fiber spinning. A lumen-side barrier layer is also successfully formed on the bore side of PAI/silica hollow fiber sorbents by using a mixture of Neoprene with cross-linking agents in a post-treatment process. The amine loaded fibers are tested in shell-and-tube modules by exposure on the shell side at 1 atm and 35 °C to simulated flue gas with an inert tracer (14 mol % CO2, 72 mol % N2, and 14 mol % He, at 100% relative humidity (RH)). The fibers show a breakthrough CO2 capacity of 0.85 mmol/g-fiber and a pseudoequilibrium CO2 uptake of 1.19 mmol/g-fiber. When tested in the temperature range of 35-75 °C, the PAI/silica/PEI fiber sorbents show a maximum CO2 capacity at 65 °C, owing to a trade-off between thermodynamic and kinetic factors. To overcome mass transfer limitations in rigidified PEI infused in the silica, an alternate PEI infusion method using a glycerol/PEI/methanol mixture is developed, and the CO2 sorption performance is improved significantly, effectively doubling the functional sorption capacity. Specifically, the glycerol-plasticized sorbents are found to have a breakthrough and equilibrium CO2 capacity of 1.3 and 2.0 mmol/g of dry fiber sorbent at 35 °C, respectively. Thus, this work demonstrates two PAI-based sorbents that are optimized for different sorption conditions with the PAI/silica/PEI sorbents operating effectively at 65 °C and the PAI/silica/PEI-glycerol sorbents operating well at 35 °C with significantly improved sorption capacity.
A hybrid positioning system for technology‐independent location‐aware computing (2009)

Abstract Location‐aware computing is a form of context‐aware mobile computing that refers to the ability of providing users with services that depend on their position. Locating the user terminal, often called positioning, is essential in this form of computing. Towards this aim, several technologies exist, ranging from personal area networking, to indoor, outdoor, and up to geographic area systems. Developers of location‐aware software applications have to face with a number of design choices, that typically depend on the chosen technology. This work addresses the problem of easing the development of pull location‐aware applications, by allowing uniform access to multiple heterogeneous positioning systems. Towards this aim, the paper proposes an approach to structure location‐aware mobile computing systems in a way independent of positioning technologies. The approach consists in structuring the system into a layered architecture, that provides application developers with a standard Java Application Programming Interface (JSR‐179 API), and encapsulates location data management and technology‐specific positioning subsystems into lower layers with clear interfaces. In order to demonstrate the proposed approach we present the development of HyLocSys. It is an open hybrid software architecture designed to support indoor/outdoor applications, which allows the uniform (combined or separate) use of several positioning technologies. HyLocSys uses a hybrid data model, which allows the integration of different location information representations (using symbolic and geometric coordinates). Moreover, it allows support to handset‐ and infrastructure‐based positioning approaches while respecting the privacy of the user. The paper presents a prototypal implementation of HyLocSys for heterogeneous scenarios. It has been implemented and tested on several platforms and mobile devices.

Cholesterolosis. Incidence, correlation with serum cholesterol level and the role of laparoscopic cholecystectomy. (2004)

Cholesterolosis of the gallbladder is a distinct pathologic entity and carries a positive correlation with high serum cholesterol level. Laparoscopic cholecystectomy is effective, safe and a feasible treatment modality for cholesterolosis.
Visions and viewpoints: promises and reality. (2005)

The immediate past chair of the ADA Council on Ethics, Bylaws and Judicial Affairs, who is also an attorney, explains why, after a thirty-year absence, he went back to treating Medicaid patients. It is easy to identify the social, political, bureaucratic, and financial shortcomings of our imperfect system. But how else, besides participating, can one educate patients so the dentist and the patient can both accept responsibility? How else can the profession make a difference except one patient at a time?
Oxygen Immunosuppression: Modification of Experimental Allergic Encephalomyelitis in Rodents (1978)

Using protocols that incorporated double blind examination of animals sensitized to CNS antigen, we confirmed and amplified earlier findings of the complete suppression of EAE in rodents by hyperbaric oxygen. The effects of O2 were related to the gas pressure and duration of treatment. The development of paralytic disease was prevented for 34 days after sensitization (the longest interval studied). Compressed air or normobaric O2 administered under similar conditions did not modify the course of illness. Within 7 to 10 days after the discontinuance of oxygen therapy the majority of treated guinea pigs developed typical signs of EAE with characteristic lesions in the CNS. The relapses occurred sooner in the Lewis rat. The development of the delayed hypersensitivity reaction to myelin basic protein and to tuberculin is also suppressed by O2 therapy indicating that its effects upon autoimmune encephalomyelitis involves fundamental alterations of the cellular components of the immune response, some or all of which are reversible.
