Electrically-activated, micromachined diaphragm valves (1990)

Electrically activated diaphragm valves have been fabricated using heated bimetallic structures to provide the operating force. These valves can be designed to provide fully proportional control of flows in the range of 0-300 cm/sup 3//min at input pressures from near zero to over 100 PSIG. The valves are batch fabricated using silicon micromachining techniques. By combining these valves with pressure or flow sensing elements, closed-loop pressure control or flow control is easily accomplished. The theory, materials, and fabrication technologies are well understood, which shortens the development time for these diaphragm valve devices. It is expected that these valves will greatly influence the types of integrated flow control systems available in the future.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Fluid-mineral reactions and trace metal mobilization in an exhumed natural CO2 reservoir, Green River, Utah (2012)

Red sandstones near Green River, Utah (United States), have been bleached by diagenetic fluids. Field relationships, modeling, fluid inclusion and isotopic data suggest that the causal fluid was a CO2-charged brine, distinguishing this site from hydrocarbon-related bleaching elsewhere on the Colorado Plateau. Mineralogical and chemical profiles from unbleached to bleached sandstone show that bleaching is related to hematite dissolution and precipitation of a 1–2 cm band of secondary oxide and carbonate at the reaction front. Trace metals are mobilized by the fluid and concentrated near the reaction front. High-flux fluid pathways are more heavily altered with large-scale secondary calcite and iron oxide precipitation. Changes may be modeled by a reaction with stoichiometry 20Fe2O3 + 5CH4 + 64CO2 + 19H2O + 11H+ = 30Fe2+ + 10FeHCO3+ + 59HCO3–. The Fe-rich, reduced fluid precipitates iron-oxides and carbonate at the reaction front between bleached and unbleached sandstone. These findings make the site an analogue for processes occurring over long time scales in geological carbon storage projects. Trace metals moblized by CO2-charged brines are likely to be rapidly re-precipitated at reaction fronts.

Exploring the Compositionality of Emotions in Text: Word Emotions, Sentence Emotions and Automated Tagging (2006)

This paper presents an approach to automated marking up of texts with emotional labels. The approach considers the representation of emotions as emotional dimensions. A corpus of example texts previously annotated by human evaluators is mined for an initial assignment of emotional features to words. This results in a List of Emotional Words (LEW) which becomes a useful resource for later automated mark up. An algorithm for the automated mark up of text is proposed. This algorithm mirrors closely the steps taken during feature extraction, employing for the actual assignment of emotional features a combination of the LEW resource, the ANEW word list, and WordNet for knowledge-based expansion of words not occurring in either. The algorithm for automated mark up is tested against texts from the original samples used for feature extraction to test its correctness. It is also tested against new text samples to test its coverage. The results are discussed with respect to two main issues: correctness and coverage of the proposed algorithm, and additional techniques and solutions that may be employed to improve the results.
A PROCESSOR EFFICIENT CONNECTIVITY ALGORITHM ON RANDOM GRAPHS (1994)

In this paper we present a randomized parallel algorithm for finding the connected components of a random input graph with n vertices in which the edges are chosen with probability p such that [Formula: see text]. The algorithm has O(log 2 n) expected time using only O(n) processors on the EREW PRAM model. The probability that the output of our algorithm is correct is at least 1–0.6 k , where k is a constant.

HPV16 status can be determined in tumor cells aspirated from the necks of patients with metastatic HNSCC. Its presence is a reliable indicator of origin from the oropharynx.
A local map based (LMB) self-healing scheme for arbitrary topology networks (2002)

A local map based (LMB) network self-healing scheme is proposed. It uses the network topology information available in small-sized data tables known as local maps, stored in each network node to restore disrupted traffic. The size of the local maps can be varied to cope with different types of failures. The time-consuming alternate path seeking process in the distributed restoration is replaced by simple searching and sorting algorithms executed in individual DCS node. This allows localized restoration and leads to significant improvement in the failure recovery time, spare resource utilization and restoration message volume. Simulations with different sets of parameters have shown that the restoration time is well below the standard 2-second service restoration objective.
Self-Calibration and Control of a PTZ Camera Based on a Spherical Mirror (2009)

In video surveillance applications, PTZ cameras can focus and analyze in details specific zones of the scene. In a computer supervised intrusion detection, a single PTZ camera is unable to visualize the entire scene at once. This article proposes an original solution to this problem, by using an additional spherical mirror. Besides the equations needed to control the PTZ camera, this article presents also a self calibration processes of the camera with the mirror.
Helicopter flight control using individual channel design (1995)

Using the multivariable analysis framework known as individual channel design (ICD), it is shown that for a typical strongly cross-coupled single main rotor helicopter at 80 knots forward flight, the standard 4-input 4-output multivariable control problem, for design purposes, decomposes without significant loss of structural (interaction) information into two simpler 2-input 2-output multivariable problems: one for the longitudinal dynamics and one for the lateral dynamics. Following on this analysis of multivariable structure, the control systems design is built up in a systematic fashion and a novel type of feedforward control is used to overcome a severe lack of robustness as well as to decouple the lateral dynamics into two SISO subsystems round crossover frequency. A diagonal (4*4) feedback controller matrix is then used, the elements of which are designed on the basis of the decoupled lateral and longitudinal dynamics. Resulting closed-loop bandwidths of all four channels are within Level 1 handling quality specifications and step responses are satisfactory with acceptably low cross-coupling.
Anti-inflammatory and analgesic activity of a water-soluble fraction from shark cartilage. (1996)

The anti-inflammatory and analgesic activities of a water-soluble fraction (WSF), extracted with 0.1 M ammonium bicarbonate, pH 8.0, from shark cartilage were studied in several experimental models. Orally administered WSF (10 mg/kg) caused 25.7 and 23.6% inhibition of the paw edema produced in female Wistar rats (200-250 g) by carrageenan and dextran, respectively, after 3 h, as compared to controls. WSF administered orally had no effect on acetic acid-induced writhings in male Swiss mice (25-30 g) at the dose of 0.01 mg/kg but caused 52.8 and 61.4% inhibition at the doses of 0.1 and 0.5 mg/kg, respectively, compared to controls (No. of writhings/20 min, means +/- SEM: treated groups = 18.6 +/- 2.5, N = 12 and 15.2 +/- 1.4, N = 12, respectively; controls = 39.3 +/- 1.3, N = 77). In the formalin test (male Swiss mice, 25-30 g), orally administered WSF (0.5 and 1 mg/kg) caused 12.0 and 46.6% inhibition of licking time, respectively, only in the 2nd phase (inflammatory) of the test (licking time, means +/- SEM: treated group = 18.3 +/- 4.4 sec, N = 7 and 11.1 +/- 3.4 sec, N = 13; controls = 20.8 +/- 2.4 sec, N = 44). The results suggest that a molecule of a protein nature in shark cartilage is probably responsible for the effects observed.

In the proposed framework, we developed a clustering based recommender system for customers, strategic objectives are statements that indicate what is critical to the final decision, and the proposed smart system has as an objective to reduce CO2 emissions, fuel consumption, and congestion by reducing the waiting time of the customers. The framework has the potential to identify more efficient and affordable solutions for traffic management and customer satisfactions.
Effects of Betaine Supplementation to Methionine Deficient Diet on Growth Performance and Carcass Characteristics of Broilers (2008)

Problem Statement: The efficacy of Methionine (Met) sparing effect of Betaine (BET) has been shown to be associated with dietary compositions, animal physiological stage and living conditions. This study was to determine the extent to which dietary Met could be replaced by BET in broiler chickens under the feeding conditions specific to Chinese poultry industry.Approach: A total of 900 day-old Arbor Acres broiler chicks were fed three corn-soybean meal-based starter rations (d 1-21) and grower rations (d 22-42) for a total of 42 days. Met levels in the diets were: Diet 1, Met content at the recommended level (Control); diet 2, Met level at 85% of the Control supplemented with BET at the level of 400 (starter) or 300 (grower) mg kg-1 DM; Diet 3, Met level at 75% of the Control supplemented with BET at the level of 600 (starter) or 500 (grower) mg khg-1 DM. The broilers were raised in a temperature controlled house with 3 pens (replicates) per dietary treatment. Results: In general, treatment had no effect on body weight, feed intake or feed efficiency. Concentrations of growth hormone and insulin-like growth factor-1 in the serum of broilers fed Diet 3 were higher (p<0.05) than that of broilers of other treatments. Supplementation of BET at the level of replacing 25% of total Met increased (p<0.05) breast meat yield and protein content of breast meat and liver, but decreased (p<0.05) abdominal fat yield and ether extract content of liver. Conclusions/Recommendations: Supplementation of BET to replace up to 25% of total dietary Met did not affect the growth performance but improved the carcass quality of the broilers. BET could be used to spare 25% of the total Met in broiler diet that was formulated based on the Feeding Standard of China.
The YIG-Tuned Gunn Oscillator, Its Potentials and Problems (1969)

The YIG-tuned Gunn oscillator has the capability of achieving broadband tuning with low residual FM noise, as good as or better than that of a reflex Klystron. Our approach to YIG-tuning a Gunn diode is shown in Fig. 1. The uniform precession mode of the YIG sphere acts as a magnetically tunable transmission type resonator. The diode and output loops are orthogonally located so that the coupling is null in the absence of the YIG sphere or magnetic field. The capability of achieving smooth, broadband tuning with medium power output with this approach is illustrated in Fig. 2. The diode was fabricated from Varian-grown, n-type, epitaxial GaAs. The carrier concentration in the solution-grown active layer was 2.5 x 10/sup 15/ cm/sup -3/. The thickness of the epitaxial layer was about 9 m. The Gunn diode was mounted in a 0.76 mm o.d. x 0.3 mm high ceramic package. The YIG sphere had an outside diameter of 1 mm, saturation magnetization of 1780 G, and a line-width of 0.5 Oe. The capability of achieving low noise oscillation, which is comparable to that of a Varian Gunn effect oscillator mounted in a waveguide cavity, is illustrated in Fig. 3. The data was taken from a diode which was oscillating at a frequency of 10.25 GHz with 40 mW of output power. Note that for modulation frequencies greater than 1 KHz from the carrier, the FM noise is as good as or better than that of an ordinary reflex Klystron. This rather good FM noise performance was achieved through circuit optimization and through improvements in the Gunn diode fabrication. The YIG-tuned Gunn oscillator was built for use with a small electromagnet having a gap of 2.8 mm. The entire oscillator, including magnet, weighs 445g and is pictured in Fig. 4.
A Self-Consistent Charge Density-Functional Based Tight-Binding Method for Predictive Materials Simulations in Physics, Chemistry and Biology (2000)

We outline recent developments in quantum mechanical atomistic modelling of complex materials properties that combine the efficiency of semi-empirical quantum-chemistry and tight-binding approaches with the accuracy and transferability of more sophisticated density-functional and post-Hartree-Fock methods with the aim to perform highly predictive materials simulations of technological relevant sizes in physics, chemistry and biology. Following Harris, Foulkes and Haydock, the methods are based on an expansion of the Kohn-Sham total energy in density-functional theory (DFT) with respect to charge density fluctuations at a given reference density. While the zeroth order approach is equivalent to a common standard non-self-consistent tight-binding (TB) scheme, at second order by variationally treating the approximate Kohn-Sham energy a transparent, parameter-free, and readily calculable expression for generalized Hamiltonian matrix elements may be derived. These matrix elements are modified by a Self-Consistent redistribution of Mulliken Charges (SCC). Besides the usual “band-structure” and short-range repulsive terms the final approximate Kohn-Sham energy explicitly includes Coulomb interaction between charge fluctuations. The new SCC-scheme is shown to successfully apply to problems, where defficiencies within the non-SCC standard TB-approach become obvious. These cover defect calculations and surface studies in polar semiconductors (see M. Haugk et al. of this special issue), spectroscopic studies of organic light-emitting thin films, briefly outlined in the present article, and atomistic investigations of biomolecules (see M. Elstner et al. of this special issue).
Resource Allocation with Subcarrier Cooperation in OFDM-Based Wireless Multicast System (2011)

In this paper, we investigate resource allocation issue in OFDM-based wireless multicast system and joint subcarrier and power allocation scheme is proposed. The optimal solution of the combinable allocation has high computational complexity, so the solution is divided into two steps. In the first step, the subcarriers are allocated to the multicast services, and all the users that have subscribed to one service share the same subcarriers. In order to increase the system capacity, a subcarrier cooperation and user grouping method is proposed. To further lower the computational complexity, a simplified method is derived. In the second step, the water-filling method is adopted to get further capacity improvement. The simulation results show that the proposed scheme performs better than the existing schemes, and the proposed simplified scheme can get a similar performance. Besides, the resource allocation schemes with multi-dimension water-filling allocation notably outperform the schemes with equal power allocation.
Breath testing for human liver function assessment (2002)

Carbon-labelled breath tests were proposed as tools for the evaluation of human liver function 30 years ago, but have never become part of clinical routine. One reason for this is the complex role of the liver in metabolic regulation, making it difficult to provide essential information for the management of patients with liver disease with a single test and to satisfy the hepatology community. As a result, a battery of breath tests have been developed. Depending on the test compound administered, different metabolic pathways (microsomal, cytosolic, mitochondrial) can be examined. Most available data come from microsomal function tests, whilst information about cytosolic and mitochondrial liver function is more limited. However, breath tests have shown promise in some studies, in particular to predict the outcome of patients with chronic liver disease or to monitor hepatic function after treatment. Whilst we await new substrates that can be used to measure liver function in a more valid manner, and large prospective studies to assess the usefulness of available test compounds, the aim of this review is to describe how far we have come in this controversial and unresolved issue.
Specific secretion of polypeptides from cells infected with vaccinia virus (1978)

The pattern of polypeptides specifically secreted by cells after infection with vaccinia virus has been analyzed. A complex pattern of apparently virus-specified polypeptides exhibiting temporal control of the type seen with intracellular polypeptides after virus infection was observed. Some of the specifically secreted polypeptides were shown to be modified by glycosylation and sulfation. The possible significance of these results is discussed.
BLOCS: A Smart Book-Locating System Based on RFID in Libraries (2007)

Recently, the wireless location system become an important issue. However, the previous location mechanisms were seldom proposed for locating applications in library. In this paper, we present a smart Book-LOCating System called BLOCS with two location modes using RFID technology -single book mode and book list mode. The single book mode provides users to find the bookshelf containing the desired book which was misplaced. The book list mode offers a corresponding list of the bookshelves and the misplaced books regularly for a librarian to localize all misplaced books in the wrong bookshelves. The simulation results show that the locating accuracies of the single book mode and the book list mode are more than 90% and 85%, respectively.
Strong expression of vascular permeability factor (vascular endothelial growth factor) and its receptors in ovarian borderline and malignant neoplasms. (1996)

Angiogenesis is a critical factor in the growth, progression, and metastatic spread of solid tumors. Furthermore, angiogenesis has been correlated with prognosis in patients with ovarian cancer. The pathogenesis of the angiogenic events in ovarian cancer, however, are not well defined. Vascular permeability factor/vascular endothelial growth factor (VPF/VEGF) is a multifunctional cytokine that has been shown to be an important regulator of tumor angiogenesis. The purpose of the present study was to define the expression of VPF/VEGF and its receptors flt-1 and KDR in ovarian tumors. Four specimens of normal ovarian cortex and 41 specimens of benign (4), borderline (8), and malignant (29) ovarian tumors were studied by in situ hybridization, and in some cases by immunohistochemical analysis. VPF/VEGF protein was also determined by an immunofluorometric assay in cyst fluids obtained from 11 patients, including 7 benign, 2 borderline, and 2 malignant tumors. VPF/VEGF mRNA and protein were expressed by the neoplastic cells in all of the malignant tumors evaluated, with the majority of tumors (28 of 29) showing strong expression of mRNA. Serous borderline tumors had variable VPF/VEGF mRNA expression, with two of six cases showing focal strong expression and four showing low-level expression. No definite expression of VPF/VEGF was seen in two cases of mucinous borderline tumors. No strong expression of VPF/VEGF mRNA was observed in normal ovarian cortex, including surface epithelium, or benign tumors. Substantially higher VPF protein concentrations were detected in cyst fluids of the two malignant (60, 440 pM) and two borderline tumors (210, 590 pM) than in the seven benign serous cysts (mean, 10 +/- 3 pM). In addition, microvascular endothelial cells strongly expressed mRNA of the VPF/VEGF receptors flt-1 and KDR and immunostained for VPF/VEGF protein in the majority of malignant and borderline tumors examined. These findings suggest that VPF/VEGF plays an important role in the angiogenesis associated with ovarian neoplasms.
The middle ground (2010)

Characteristics of electron cyclotron resonance plasma sources (1989)

Electron cyclotron resonance plasmas were excited at a frequency of 2.45 GHz in chambers with diameters smaller and larger than cutoff ones for fundamental TE and TM modes. Microwaves were introduced in the plasma chambers from the cw generator via a vacuum window and the microwave transmission line. It was found that microwave breakdowns at pressures 10−5–10−1 Torr (argon, nitrogen, oxygen) occurred at sites where the static magnetic field was 875 G (or close). In chambers with diameter smaller than cutoff, the breakdown occurred only near the vacuum window. A high absorption level of microwave power (&gt;95%) was achieved in all explored chambers at microwave power P=300–1000 W. It occurred at areas where the static magnetic field was ∼875 G and the plasma density was Ncr=7.4×1010 cm−3. A high microwave power absorption level resulted in high plasma density up to Ne=1012 cm−3 at P=1000 W. No saturation in Ne=f(P) was observed. The shape and location of the high plasma density area was determined by microwave matching tuning, magnetic field and its configuration, and source chamber size.
