Evaluation of selected mathematical approaches to the kinetics of protein degradation in situ. (1998)

A linear model, two mathematical nonlinear models, and a curve-peeling procedure were used to estimate rate and extent of ruminal CP degradation of meat and bone meal (MBM) and soybean meal (SBM) from data obtained using the in situ Dacron polyester bag technique. Most of the values for extent of CP degradation of MBM were lowest when determined using curve peeling or the nonlinear models. In general, rates and extents of CP degradation of MBM estimated using the linear model and including ruminal incubations up to 12 h were greater than those obtained with the linear model and including ruminal incubations up to 24 h or up to 72 h. In addition, the models ranked the MBM samples differently for rate and extent of CP degradation. The results of the lack-of-fit test indicated that the linear model was inappropriate for estimating rate of degradation of MBM. However, CP degradation for SBM could be described by the linear model if long ruminal incubation times (greater than 48 h) were included in the calculations. Regression analyses were conducted to evaluate various compositional characteristics as predictors of CP degradation for MBM. Most of the correlation coefficients between CP degradation and the same independent variables were greater when the nonlinear models and curve peeling were used compared with the linear model. In general, the correlation coefficients between extent of CP degradation and the independent variables obtained with the linear model increased as the duration of ruminal incubations included in the model increased. Lysine concentrations, followed by CP solubility and ash content, were the best predictors of ruminal degradation of MBM protein. When using a specific mathematical model to predict CP degradation, analysis of residuals vs fitted and lack-of-fit tests should be performed to assess the validity of the model to describe the degradation patterns of the protein source under consideration. Also, long (at least 48 h) ruminal incubation times may be needed to correctly describe the pattern of CP degradation for MBM.
Propagation and optical interaction of guided acoustic waves in two-mode optical fibers (1988)

Acoustic modes propagating in cylindrical solid rods are considered. A review of the properties of several mode groups is given, and computed results are shown for a wide range of material properties. The lower mode of each group is relevant for an all-fiber-optic frequency shifter recently demonstrated. For these modes, dispersion relations, mode patterns, power relations, and acoustooptic coupling strength are calculated. Some experimental results are compared with the calculations, and alterations to improve the frequency shifter are proposed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A reaction periodic in time and space. A lecture demonstration (1972)

Today's style sheet standards: the great vision blinded (1999)

Our research into style sheet systems and languages (Proteus and PSL) shows that there are alternatives to CSS and XSL that more closely meet the necessary criteria. The PSL style language has a syntax especially designed for the style sheet task and has traditional computational features including mathematical expressions and conditionals. In contrast to XSL, PSL does not emphasize transformations, and it uses constraints, rather than flow, to specify layout. Furthermore, there are other style languages, such as the Thot structured document toolkit's P language and the more recent Constraint CSS. While we realize that substantial resources have been invested in CSS and XSL, we nevertheless urge the Web community to more fully explore alternate approaches to style sheets.
Application-Screen Masking: A Hybrid Approach (2015)

Large organizations often face difficult tradeoffs in balancing the need to share information with the need to safeguard sensitive data. A prominent way to deal with this tradeoff is on-the-fly screen masking of sensitive data in applications. A proposed hybrid approach for masking Web application screens combines the advantages of the context available at the presentation layer with the flexibility and low overhead of masking at the network layer. This solution can identify sensitive information in the visual context of the application screen and then automatically generate the masking rules to enforce at run time. This approach supports the creation of highly expressive masking rules, while keeping rule authoring easy and intuitive, resulting in an easy to use, effective system. This article is part of a special issue on Security and Privacy on the Web. The Web extra at https://youtu.be/4u2FLqjaIiI is a short demonstration of a proposed hybrid approach for masking Web application screens that combines the advantages of the context available at the presentation layer with the flexibility and low overhead of masking at the network layer. The second Web extra at https://youtu.be/-Hz3P_H0UnU is a full-length demonstration of a proposed hybrid approach for masking Web application screens that combines the advantages of the context available at the presentation layer with the flexibility and low overhead of masking at the network layer.
Microassembled tunable mems inductor (2005)

In this work we present a heterogeneous microassembly consisting of a MEMS translation stage, a copper electroplated solenoid inductor, and a ferromagnetic NiFe core, integrated on a Pyrex sub-mount. The system was assembled by a 5 degree-of-freedom automated motion control platform using hybrid MEMS assembly technology and a design library of silicon microgrippers, sockets and handles. The tunable inductor was characterized using various core materials from 300 kHz to 20 GHz and has a self-resonant frequency (SRF) of 10 GHz, a Q over 50, and inductance values from 5.5 to 40 nH over its useful frequency range. A nanomagnetic composite material containing Co/sub 83.2/B/sub 3.3/Si/sub 5.9/Mn/sub 7.6/ exhibited continuous enhancement in inductance and Q up to the self-resonant frequency of the device. The device operates on 7 volts and consumes no quiescent power once it is tuned, due to the power-off engage mechanism incorporated in the translation stage.
Coadministration of dimethyl sulfoxide reduces cisplatin nephrotoxicity. (1992)

The administration of dimethyl sulfoxide with cisplatin at a mole ratio of 200:1 results in a considerable reduction in the nephrotoxicity produced when cisplatin alone is administered to Sprague-Dawley rats at 7.5 mg/kg. Observed measures of nephrotoxicity which were significantly improved by the coadministration of cisplatin and DMSO over the values found for cisplatin alone include BUN, serum creatinine, creatinine clearance and histopathological evidence of renal damage. The weight loss associated with cisplatin administration was also significantly reduced by DMSO coadministration. The use of DMSO did not result in any observable loss in antitumor activity of cisplatin against the Walker 256 carcinosarcoma.
MethyLight droplet digital PCR for detection and absolute quantification of infrequently methylated alleles (2015)

Aberrant DNA methylation is a common epigenetic alteration found in colorectal adenomas and cancers and plays a role in cancer initiation and progression. Aberrantly methylated DNA loci can also be found infrequently present in normal colon tissue, where they seem to have potential to be used as colorectal cancer (CRC) risk biomarkers. However, detection and precise quantification of the infrequent methylation events seen in normal colon is likely beyond the capability of commonly used PCR technologies. To determine the potential for methylated DNA loci as CRC risk biomarkers, we developed MethyLight droplet digital PCR (ddPCR) assays and compared their performance to the widely used conventional MethyLight PCR. Our analyses demonstrated the capacity of MethyLight ddPCR to detect a single methylated NTRK3 allele from among more than 3125 unmethylated alleles, 25-fold more sensitive than conventional MethyLight PCR. The MethyLight ddPCR assay detected as little as 19 and 38 haploid genome equivalents of methylated EVL and methylated NTRK3, respectively, which far exceeded conventional MethyLight PCR (379 haploid genome equivalents for both genes). When assessing methylated EVL levels in CRC tissue samples, MethyLight ddPCR reduced coefficients of variation (CV) to 6-65% of CVs seen with conventional MethyLight PCR. Importantly, we showed the ability of MethyLight ddPCR to detect infrequently methylated EVL alleles in normal colon mucosa samples that could not be detected by conventional MethyLight PCR. This study suggests that the sensitivity and precision of methylation detection by MethyLight ddPCR enhances the potential of methylated alleles for use as CRC risk biomarkers.
A DHA14 drug efflux gene from Xanthomonas albilineans confers high-level albicidin antibiotic resistance in Escherichia coli (2006)

Development of the clinical potential of albicidins as potent bactericidial antibiotics against diverse bacteria has been limited because of low yields in culture. Expression of albF with recently described albicidin-biosynthesis genes may enable large-scale production. Because albicidins are X. albilineans pathogenicity factors, interference with AlbF function is also an opportunity for control of the associated plant disease.
General anesthesia with spontaneous ventilation without intubation for short-stay operations. (2002)

Ricinoleic acid-based biopolymers (1999)

Polyanhydrides synthesized from pure ricinoleic acid half-esters with maleic and succinic anhydrides possess desired physicochemical and mechanical properties for use as drug carriers. Ricinoleic acid maleate or succinate diacid half-esters were prepared from the reaction of crude ricinoleic acid (85% content) with succinic or maleic anhydride. The pure diacid monomers were obtained by chromatography purification through silica gel using petroleum ether/ethyl acetate/acetic acid (80/30/1 v/v/v) mixture as eluent. The pure diacid monomers (>99%) were polymerized by melt condensation to yield film-forming polymers with molecular weights exceeding 40,000 with a polydispersity of 2. Extensive biocompatibility study demonstrated their toxicological inertness and biodegradability. Their rate of elimination from rats in the course of about 4-6 weeks was faster than that found for similar fatty acid-based polyanhydrides previously tested. In vitro studies showed that these polymers underwent rapid hydrolytic degradation in 10 days. Methotrexate release from the polymers was not affected by the initial polymer molecular weight in the range of 10,000-35,000. The in vitro drug release correlated with the degradation of the polymers. The fatty acid ester monomers were further degraded to its counterparts, ricinoleic acid and succinic or maleic acid.
Plasmodium Falciparum Strain-Specific Human Antibody Inhibits Merozoite Invasion of Erythrocytes (1984)

The extent to which human antibodies involved in functional immunity react with antigenic determinants varying between different isolates or strains of the human malaria parasite Plasmodium falciparum will influence the design of vaccines against malaria. We identified nine immune sera from Cambodian refugees which blocked in vitro invasion of erythrocytes by merozoites of the Camp strain of P. falciparum and agglutinated Camp strain merozoites. However, none of these sera blocked invasion of erythrocytes by merozoites of the FCR-3 strain. We conclude that antibodies in these human sera recognized antigenic determinants present on the surface of viable merozoites of the Camp strain but not the FCR-3 strain. These parasite strains and in vitro assays can be used to analyze strain-specific functional immunity in humans.
Selective Catalytic Reduction of NO by NH <sub>3</sub> in Flue Gases over a Cu-V/Al <sub>2</sub> O <sub>3</sub> Catalyst at Low Temperature (2009)

A novel copper-based catalyst with vanadium as a promoter has been synthesized and evaluated for its efficiency on the selective catalytic reduction of nitric oxide (NO) in flue gases using ammonia (NH3) as a reductant in the temperature range of 50–500°C. The Brunauer-Emmett-Teller method, Energy Dispersive X-ray Spectrometry and Scanning Electron Microscopy have been used to characterize the catalysts developed. Effects of reaction parameters including temperature, space velocity, O2 concentration, and the ratio of NH3 to NO on the selective catalytic reduction of NO by NH3 on the synthesized catalyst, as well as the chemical mechanisms and the side reactions involved have been examined. The catalyst shows high activity for NO conversion (89.6%) with a NH3/NO ratio of about 1 in the presence of oxygen (O2) (∼3.0% v/v) at a temperature of 200°C. At a temperature of 200°C or below, only selective (desirable) catalytic reactions occur. NH3 was gradually oxidized to NO and nitrogen dioxide (NO2) at temperatures above 200°C, and thus led to a low NO removal efficiency. NO conversion also increased with decreasing space velocity between 3,600 and 7,800 h−1. Results indicate that the Cu-V/Al2O3 is a very promising and green catalyst for the elimination of NO using NH3 as a reductant in flue gases at low temperatures, and could be further developed as an efficient selective catalytic reduction (SCR)-catalytic converter for removing NO from diesel vehicle exhausts.
Building an Intranet (1996)

Over a period of five and a half years, 792 inpatients with benzodiazepine (BZD) abuse and dependence in accordance with the WHO definition were registered at a university psychiatric hospital. One-quarter of them abused BZD exclusively, while three-quarters suffered from polytoxicomania or were alcohol dependent as well. It was possible to distinguish two groups of patients: one with primary, mainly low-dose, dependence preferring lorazepam and the other with secondary, often high-dose, dependence with diazepam as the main drug. In 108 patients with isolated BZD dependence, withdrawal symptoms of somatic, psychological, or perceptual quality were observed. The severity of the withdrawal syndrome seemed to depend on the time of consumption, dose, mode of withdrawal, and type of BZD compound. Following abrupt cessation, 11 patients with long-standing dependence on high BZD doses developed withdrawal psychoses, presenting a delirious, paranoid-hallucinatory, or depressive-anxious syndrome.
Heterogeneity of protein–polysaccharides of porcine articular cartilage. The sequential extraction of chondroitin sulphate–proteins with iso-osmotic neutral sodium acetate (1971)

Protein-polysaccharides of knee-joint cartilage of 9-month-old pigs were extracted sequentially with neutral iso-osmotic sodium acetate after five repeated homogenizations. One-third of the uronic acid originally present in the tissue was brought into solution, about half being in the first extract. The protein-polysaccharides, which were purified by precipitation with 9-aminoacridine, were heterogeneous in size on gel chromatography. The smallest (retarded by 6% agarose) were the most easily extracted since they were most prevalent in the initial extracts and absent from later ones, whereas the proportion of larger molecules increased progressively in successive extracts. Nevertheless a small proportion of the largest molecules (excluded from Sepharose 2B) was present even in the first extract. None of the protein-polysaccharide preparations contained hydroxyproline, and the analyses of their constituent sugars were the same, although there was a progressive increase in the protein content and in the glucosamine/galactosamine molar ratio of successive extracts. In each preparation this molar ratio was invariably greater in larger than in smaller molecules separated by gel filtration. From galactosamine/pentose molar ratios it appeared that the chondroitin sulphate chains were on average about 29 disaccharide units in length in the protein-polysaccharides of each extract, although gel-chromatography and cetylpyridinium chloride elution profiles showed that a somewhat higher proportion of shorter chondroitin sulphate chains occurred in the larger protein-polysaccharides. In the last extract, where the largest molecules predominated, about half could be reversibly dissociated by urea, whereas this had no effect on the protein-polysaccharides of earlier extracts even though these contained some large molecules.

Glove-Based Continuous Arabic Sign Language Recognition in User-Dependent Mode (2015)

In this paper, we propose a glove-based Arabic sign language recognition system using a novel technique for sequential data classification. We compile a sensor-based dataset of 40 sentences using an 80-word lexicon. In the dataset, hand movements are captured using two DG5-VHand data gloves. Data labeling is performed using a camera to synchronize hand movements with their corresponding sign language words. Low-complexity preprocessing and feature extraction techniques are applied to capture and emphasize the temporal dependence of the data. Subsequently, a Modified k-Nearest Neighbor (MKNN) approach is used for classification. The proposed MKNN makes use of the context of feature vectors for the purpose of accurate classification. The proposed solution achieved a sentence recognition rate of 98.9%. The results are compared against an existing vision-based approach that uses the same set of sentences. The proposed solution is superior in terms of classification rates while eliminating restrictions of vision-based systems.
Oral Rehydration Solutions in Non-Cholera Diarrhea: A Review (2009)

The use of oral rehydration solution (ORS) has revolutionized the management of acute diarrhea. The implementation of the standard World Health Organization ORS (WHO-ORS) has resulted in decreased mortality associated with acute diarrheal illnesses in children, although in general stool volume and diarrhea durations are not reduced. Decreased morbidity and mortality have occurred because of improved hydration status. Decreased morbidity has also been described in adults who used this therapy. Various modifications to the standard ORS have been derived. These modifications have included hypo-osmolar or hyperosmolar solutions, use of rice-based ORS, zinc supplementation, and the use of amino acids, including glycine, alanine, and glutamine. Some of these variations have been successful, some have not, and others are still under investigation. ORS has been used for travelers' diarrhea and to decrease intravenous (IV) fluid requirements in patients with short bowel syndrome (SBS) who require parenteral nutrition (PN). This paper reviews the standard WHO-ORS and its mechanism of action, followed by more contemporary reduced osmolarity ORS and rice-based ORS in non-cholera diarrhea. Various modifications to improve ORS are also discussed.
Switched-current memory circuits for high-precision applications (1994)

We discuss circuit parameters that limit the precision of basic dynamic current-memory cells. In addition to analyzing current-copying errors caused by the finite output conductances of the current sources and by the clock-feedthrough (CFT) of the feedback switches, we analyze the noise performance of the basic memory cell. To reduce CFT and noise, we propose a novel circuit based on Miller capacitance-enhancement. Measurement results of memory cells integrated in a 1-/spl mu/m CMOS process confirm the theoretical findings; with our CFT and noise reduction technique based on Miller enhanced capacitance and dummy switches, we achieve a dynamic range of 11 b at clock frequencies greater than 100 kHz.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
