An ISDN echo-cancelling transceiver chip for 2B1Q coded U-interface (2003)

A 5-V CMOS chip set used for an integrated services digital network (ISDN) U-interface transceiver is described which accomplishes 2B+D channel (144-kb/s) transmission using a 2B1Q line code based on echo cancellation over existing two-wire subscriber loops. The three-chip set consists of an analog front end (AFE), an echo canceler (ECD) and a receiver (RCV). The last two are digital signal processors. The AFE has been fabricated in double-polysilicon double-metal 1.6 mu m CMOS technology. The chip size is 7.5 mm*6.5 mm. The EC and RCV have been fabricated in double-metal 1.2- mu m CMOS technology using a standard-cell design. The chip sizes are 8.2 mm*8.2 mm and 8.5 mm*8.1 mm, respectively. Total power consumption of the chip set is 580 mW with a single 5-V supply.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Novel Method for Fingerprint Core Point Detection (2011)

Abstract- Fingerprint recognition is a method of biometric authentication that uses pattern recognition techniques based on highresolution fingerprints images of the individual. Fingerprints have been used in forensic as well as commercial applications for identification as well as verification. Singular point detection is the most important task of fingerprint image classification operation. Two types of singular points called core and delta points are claimed to be enough to classify the fingerprints. The classification can act as an important indexing mechanism for large fingerprint databases which can reduce the query time and the computational complexity. Usually fingerprint images have noisy background and the local orientation field also changes very rapidly in the singular point area. It is difficult to locate the singular point precisely. There already exists many singular point detection algorithms, Most of them can efficiently detect the core point when the image quality is fine, but when the image quality is poor, the efficiency of the algorithm degrades rapidly. In the present work, a new method of detection and localization of core points in a fingerprint image is proposed.
Health Plan Characteristics And Consumers’ Assessments Of Quality (2001)

Many purchasers and consumers of health care have become concerned about the quality of care being delivered in managed care plans. Little is known, however, about the health plan characteristics that are associated with better performance. We used survey responses from 82,583 Medicare beneficiaries from 182 health plans to study the association of consumers' assessments of care with health plan characteristics. For-profit and nationally affiliated health plans received much worse scores on the outcomes of interest, particularly for overall ratings of the health plan and composite measures of customer service and access to care. Health plans accredited by the National Committee for Quality Assurance did not receive higher scores.
Airborne Contamination in Orthopedic Surgery (1977)

Commercial office buildings represent the largest in floor area in most developed countries and utilize substantial amount of energy in the provision of building services to satisfy occupants’ comfort needs. This makes office buildings a target for occupant-driven demand control measures, which have been demonstrated as having huge potential to improve energy efficiency. The application of occupant-driven demand control measures in buildings, most especially in the control of thermal, visual and indoor air quality providing systems, which account for over 30% of the energy consumed in a typical office building is however hampered due to the lack of comprehensive fine-grained occupancy information. Given that comprehensive fine-grained occupancy information improves the performance of demand-driven measures, this paper presents a review of common existing systems utilized in buildings for occupancy detection. Furthermore, experimental results from the performance evaluation of chair sensors in an office building for providing fine-grained occupancy information for demand-driven control applications are presented.
Adsorption of Phosphate on Manganese Dioxide in Seawater (1996)

The adsorption of phosphate on manganese dioxide (δMnO2) was determined in seawater as a function of pH, temperature, and salinity. The adsorption in a simple electrolyte solution (0.7 M NaCl) was adequately fitted using the triple-layer surface complexation model, assuming that phosphate formed outer-sphere complexes on the surface of δMnO2. SO42- and humic acid were found to suppress the adsorption at low pH, but had no effect in the pH range of seawater. The addition of Ca2+ and Mg2+ in 0.7 M NaCl was found to enhance the adsorption of phosphate on δMnO2 at pH > 4. This increased adsorption might be due to the changes in both the surface charge of δMnO2 and the solution speciation of phosphate in the presence of Ca2+ and Mg2+. The results suggest that manganese oxides can act as important adsorbents of phosphate in natural waters, as well as in surface sediments, when they are present at higher concentrations than other reactive constituents, such as iron and aluminum oxides.
Ovulation and Reproductive Hormones following Steroid Pretreatment, Calf Removal and GnRH in Postpartum Suckled Beef Cows (1980)

Two experiments were conducted to determine the effect of calf removal, steroid pretreatment and treatment with gonadotropin releasing hormone (GnRH) on subsequent reproductive hormone secretion and ovulation. In the first experiment, GnRH was administered to postpartum beef cows at two levels (100 and 250 microgram) and in two carrier vehicles (saline and carboxymethylcellulose [CMC]). Although peak luteinizing hormone (LH) concentrations were similar for all cows, the interval from treatment to peak LH release and the duration of the LH release was prolonged (P < .05) in the cows that were given GnRH in CMC. In the second experiment, 30 postpartum suckled beef cows were assigned to a 2 X 3 factorial experiment, with calf removal (none or short-term) and steroid pretreatment (none, norgestomet implant or Synchro-Mate B) as main effects. Short-term calf removal consisted of a 36-hr nonsuckling period beginning at the time of implant removal. GnRH (250 microgram in CMC) was injected subcutaneously 24 hr after implant and calf removal. An increased GnRH-induced LH release due to short-term calf removal (P < .05) and steroid pretreatment (P < .10) was detected. The interaction was not significant, however, (P < .25). Therefore, the suckling-induced suppression of pituitary LH release to exogenous GnRH can be at least partially eliminated within 24 hr of calf separation of norgestomet implant removal. The GnRH-induced LH release was correlated with pretreatment concentrations of estradiol-17 beta for cows that were not separated from their calves (r = .61; P < .05) but not for cows that were subjected to short-term calf removal (r = .28; P > .10). Ovulation occurred in all cows (100%) that were separated from their calves and given GnRH, whereas only 67% of cows not subjected to calf removal ovulated following GnRH treatment. Although the ovulation responses differed (P < .025) between cows that were and were not separated from their calves, ovulation response was not affected by steroid pretreatment (P > .10).
Corneal Stromal Cell Growth on Gelatin/Chondroitin Sulfate Scaffolds Modified at Different NHS/EDC Molar Ratios (2013)

A nanoscale modification strategy that can incorporate chondroitin sulfate (CS) into the cross-linked porous gelatin materials has previously been proposed to give superior performance for designed corneal keratocyte scaffolds. The purpose of this work was to further investigate the influence of carbodiimide chemistry on the characteristics and biofunctionalities of gelatin/CS scaffolds treated with varying N-hydroxysuccinimide (NHS)/1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide hydrochloride (EDC) molar ratios (0-1) at a constant EDC concentration of 10 mM. Results of Fourier transform infrared spectroscopy and dimethylmethylene blue assays consistently indicated that when the NHS to EDC molar ratio exceeds a critical level (i.e., 0.5), the efficiency of carbodiimide-mediated biomaterial modification is significantly reduced. With the optimum NHS/EDC molar ratio of 0.5, chemical treatment could achieve relatively high CS content in the gelatin scaffolds, thereby enhancing the water content, glucose permeation, and fibronectin adsorption. Live/Dead assays and interleukin-6 mRNA expression analyses demonstrated that all the test samples have good cytocompatibility without causing toxicity and inflammation. In the molar ratio range of NHS to EDC from 0 to 0.5, the cell adhesion ratio and proliferation activity on the chemically modified samples significantly increased, which is attributed to the increasing CS content. Additionally, the materials with highest CS content (0.143 ± 0.007 nmol/10 mg scaffold) showed the greatest stimulatory effect on the biosynthetic activity of cultivated keratocytes. These findings suggest that a positive correlation is noticed between the NHS to EDC molar ratio and the CS content in the biopolymer matrices, thereby greatly affecting the corneal stromal cell growth.
Port and Maritime Security: Background and Issues for Congress (2005)

The terrorist attacks of September 11, 2001 heightened awareness about the vulnerability to terrorist attack of all modes of transportation. Port security has emerged as a significant part of the overall debate on U.S. homeland security. The overarching issues for Congress are providing oversight on current port security programs and making or responding to proposals to improve port security. The U.S. maritime system consists of more than 300 sea and river ports with more than 3,700 cargo and passenger terminals. However, a large fraction of maritime cargo is concentrated at a few major ports. Most ships calling at U.S. ports are foreign owned with foreign crews. Container ships have been the focus of much of the attention on seaport security because they are seen as vulnerable to terrorist infiltration. More than 9 million marine containers enter U.S. ports each year. While the Bureau of Customs and Border Protection (CBP) analyzes cargo and other information to target specific shipments for closer inspection, it physically inspects only a small fraction of the containers.
Effect of micellar beta-sitosterol on cholesterol metabolism in CaCo-2 cells (1997)

CaCo-2 cells were used to address the effect of the plant sterol, beta-sitosterol, on cholesterol trafficking, cholesterol metabolism, and apoB secretion. Compared to cells incubated with micelles (5 mM taurocholate and 250 microM oleic acid) containing cholesterol, which caused an increase in the influx of plasma membrane cholesterol to the endoplasmic reticulum and increased the secretion of cholesteryl esters derived from the plasma membrane, beta-sitosterol did not alter cholesterol trafficking or cholesteryl ester secretion. Including beta-sitosterol in the micelle together with cholesterol attenuated the influx of plasma membrane cholesterol and prevented the secretion of cholesteryl esters derived from the plasma membrane. Stigmasterol and campesterol had effects similar to beta-sitosterol, although campesterol did not promote a modest influx of plasma membrane cholesterol. Including beta-sitosterol in the micelle with cholesterol decreased the uptake of cholesterol. Compared to cholesterol, 60%less beta-sitosterol was taken up by CaCo-2 cells. No observable esterification of beta-sitosterol was appreciated and the transport of the plant sterol to the basolateral medium was negligible. Cholesterol synthesis and HMG-CoA reductase activities were decreased in cells incubated with beta-sitosterol. This was associated with a decrease in reductase mass and mRNA levels. Cholesteryl ester synthesis and ACAT activities were unaltered by beta-sitosterol. Both stigmasterol and campesterol decreased reductase activity, but only campesterol increased ACAT activity. beta-sitosterol did not affect the secretion of apoB mass. The results suggest that beta-sitosterol does not promote cholesterol trafficking from the plasma membrane to the endoplasmic reticulum. beta-sitosterol interferes with the uptake of micellar cholesterol causing less plasma membrane cholesterol to influx and less cholesteryl ester to be secreted. Despite its lack of effect on cholesterol trafficking, beta-sitosterol decreases cholesterol synthesis at the level of HMG-CoA reductase gene expression.
Ultraviolet Curable Ceramic Suspensions for Stereolithography of Ceramics (1994)

Abstract Ceramic green bodies can be created using stereolithography methods where a ceramic slip consisting of 45-55 v/o ceramic powder is dispersed within a curable ultraviolet solution. In this study, two ultraviolet solutions were examined, an aqueous-acrylamide solution and a low viscosity diacrylate. Of the ceramic materials possible, two were investigated: silica, SiO2, for investment casting purposes, and silicon nitride, Si3N4, for structural parts. After mixing the powders in the curable solution, the ceramic slip is tape cast onto a substrate for cure under a high intensity ultraviolet lamp (220-450 nm) at different exposure times. The materials systems were evaluated at different solids loadings (5-50 v/o) for cure thickness and viscosity control. Silica had a cure depth of 330 μm at a solids loading of 55 v/o, where silicon nitride had a depth of cure of 60 μm at 30 v/o. Preliminary work utilizing scattering theory revealed the cure depth is controlled by the particle size and the refractive index difference between the ceramic and ultraviolet solution. The silicon nitride powder had a smaller particle size and the slip had a larger refractive index term, and this resulted in a lower depth of cure.
CH-SVM Based Network Anomaly Detection (2007)

Network anomaly detection is a critical task to ensure network security. With increasing network traffic, detecting network anomaly would require solving a large-scale pattern classification problem that often contains millions of training vectors. Each training vector may represent a particular signature of network traffic pattern and some of them may be linked to security breaching activities that need to be detected and eradicated. In this paper, a popular statistical learning algorithm known as the support vector machine (SVM) was consider to solve the network anomaly detection problem. However, it is well known that SVM would require excessively long computing time and exceedingly large amount of memory when number of training vectors becomes huge. Hence, direct application of the standard SVM algorithm to solve large-scale network anomaly detection problems is impractical. In this paper, based on computational geometry theory, a new algorithm called convex-hull SVM (CH-SVM) was proposed, which can yield the same solution as original SVM while using significantly less training data, and hence less computing time. Then experiments were done on KDD'99 intrusion detection dataset to compare the performance of the proposed algorithm to a standard SVM and observed reduced training time and improved classification accuracy.

Social and Range Dominance in Gallinaceous Birds: Pheasants and Prairie Grouse (1957)

The sea otter and harbor seal inhabit the same coastal waters and the rocky beaches and reefs. They provide an example of two fairly large, carnivorous, littoral mammals which are virtually noncompetitive. There is only a slight overlap in their food habits in the same locality. The otter feeds largely on echinoderms and shell-bearing mollusks, whereas the harbor seal depends mostly on freeswimming cephalopods and fishes.
Pharmaceutical development of ondansetron injection. (1989)

Ondansetron injection is an aqueous solution containing ondansetron base as the hydrochloride dihydrate. The pH of the injection was selected to achieve good physical and chemical stability. The shelf life is 3 years when stored below 30 degrees C, protected from light. Ondansetron injection may be diluted for administration by slow intravenous injection or infusion and is compatible with several intravenous infusion fluids. In addition, specific concentrations of cisplatin, 5-fluorouracil, carboplatin, etoposide, ceftazidime, cyclophosphamide and doxorubicin are compatible when administered via a giving set delivering ondansetron by infusion.
Seismic wave propagation in cracked porous media (2000)

The movement of interstitial fluids within a cracked solid can have a significant effect on the properties of seismic waves of long wavelength propagating through the solid. We consider three distinct mechanisms of wave-induced fluid flow: flow through connections between cracks in an otherwise non-porous material, fluid movement within partially saturated cracks, and diffusion from the cracks into a porous matrix material. In each case the cracks may be aligned or randomly oriented, leading, respectively, to anisotropic or isotropic wave speeds and attenuation factors. In general, seismic velocities exhibit behaviour that is intermediate between that of empty cracks and that of isolated liquid-filled cracks if fluid flow is significant. In the range of frequencies for which considerable fluid flow occurs there is high attenuation and dispersion of seismic waves. Fluid flow may be on either a wavelength scale or a local scale depending on the model and whether the cracks are aligned or randomly oriented, resulting in completely different effects on seismic wave propagation. A numerical analysis shows that all models can have an effect over the exploration seismic frequency range.

Carbon monoxide – physiology, detection and controlled release (2014)

Carbon monoxide (CO) is increasingly recognized as a cell-signalling molecule akin to nitric oxide (NO). CO has attracted particular attention as a potential therapeutic agent because of its reported anti-hypertensive, anti-inflammatory and cell-protective effects. We discuss recent progress in identifying new effector systems and elucidating the mechanisms of action of CO on, e.g., ion channels, as well as the design of novel methods to monitor CO in cellular environments. We also report on recent developments in the area of CO-releasing molecules (CORMs) and materials for controlled CO application. Novel triggers for CO release, metal carbonyls and degradation mechanisms of CORMs are highlighted. In addition, potential formulations of CORMs for targeted CO release are discussed.
