Dempster-Shafer Theory based Classifier Fusion for Improved Fingerprint Verification Performance (2008)

Abstract. This paper presents a Dempster Shafer theory based classifier fusion algorithm to improve the performance of fingerprint verification. The proposed fusion algorithm combines decision induced match scores of minutiae, ridge, fingercode and pore based fingerprint verification algorithms and provides an improvement of at least 8.1 % in the verification accuracy compared to the individual algorithms. Further, proposed fusion algorithm outperforms by at least 2.52 % when compared with existing fusion algorithms. We also found that the use of Dempster’s rule of conditioning reduces the training time by approximately 191 seconds. 1
Unwelcome Complement (2009)

For decades, the complement system has been recognized as an effector arm of the innate immunity system that contributes to the destruction of tumor cells. However, recent studies have challenged this paradigm by demonstrating that a complement component, the anaphylatoxin C5a, promotes the growth of malignant tumors in a mouse model of cervical carcinoma. The effect of C5a on tumor growth was associated with the recruitment of myeloid-derived suppressor cells to tumors, followed by the activation of these cells. These unexpected findings identify the complement system as a potential new target for anticancer immunotherapy.
GaAs–oxide interface states: Gigantic photoionization via Auger-like process (1981)

Spectral and transient responses of photostimulated current in MOS structures were employed for the study of GaAs–anodic oxide interface states. Discrete deep traps at 0.7 and 0.85 eV below the conduction band were found with concentrations of 5×1012 cm−2 and 7×1011 cm−2, respectively. These traps coincide with interface states induced on clean GaAs surfaces by oxygen and/or metal adatoms (submonolayer coverage). In contrast to surfaces with low oxygen coverage, the GaAs-thick oxide interfaces exhibited a high density (about 1014 cm−2) of shallow donors and acceptors. Photoexcitation of these donor–acceptor pairs led to a gigantic photoionization of deep interface states with rates 103 times greater than direct transitions into the conduction band. The gigantic photoionization is explained on the basis of energy transfer from excited donor–acceptor pairs to deep states.
Longitudinal course and neuropathologic outcomes in original vs revised MCI and in pre-MCI (2006)

Mild cognitive impairment as originally and currently defined is usually early stage Alzheimer disease, which can begin with a cognitive deficit other than memory. It is possible to identify Alzheimer disease at an even earlier stage than mild cognitive impairment by focusing on intraindividual change rather than comparison with group norms.
Epidemiology of pre-eclampsia and eclampsia at the KK Women's and Children's Hospital, Singapore. (2006)

The incidence and outcome of eclampsia in KKH showed a significant reduction over the years due to improved obstetrical care. While PE is still common, eclampsia is now a very rare disease outcome.

Thermal Conductivity of Silicon and Germanium from 3°K to the Melting Point (1964)

The thermal conductivity $K$ of single crystals of silicon has been measured from 3 to 1580\ifmmode^\circ\else\textdegree\fi{}K and of single crystals of germanium from 3 to 1190\ifmmode^\circ\else\textdegree\fi{}K. These measurements have been made using a steady-state, radial heat flow apparatus for $T>300\ifmmode^\circ\else\textdegree\fi{}$K and a steady-state, longitudinal flow apparatus for $T<300\ifmmode^\circ\else\textdegree\fi{}$K to give absolute $K$ values. This radial flow technique eliminates thermal radiation losses at high temperatures. The accuracy of both the low-temperature apparatus and the high-temperature apparatus is approximately \ifmmode\pm\else\textpm\fi{}5%. Some special experimental techniques in using the high-temperature apparatus are briefly considered. At all temperatures the major contribution to $K$ in Si and Ge is produced by phonons. The phonon thermal conductivity has been calculated from a combination of the relaxation times for boundary, isotope, three-phonon, and four-phonon scattering, and was found to agree with the experimental measurements. Above 700\ifmmode^\circ\else\textdegree\fi{}K for Ge and 1000\ifmmode^\circ\else\textdegree\fi{}K for Si an electronic contribution to $K$ occurs, which agrees quite well with the theoretical estimates. At the respective melting points of Si and Ge, electrons and holes are responsible for 40% of the total $K$ and phonons are responsible for 60%. The measured electronic $K$ yields values for the thermal band gap at the melting point of 0.6\ifmmode\pm\else\textpm\fi{}0.1 eV for Si and 0.26\ifmmode\pm\else\textpm\fi{}0.08 eV for Ge.
Confronting the Challenge of Quality Diversity (2015)

In contrast to the conventional role of evolution in evolutionary computation (EC) as an optimization algorithm, a new class of evolutionary algorithms has emerged in recent years that instead aim to accumulate as diverse a collection of discoveries as possible, yet where each variant in the collection is as fit as it can be. Often applied in both neuroevolution and morphological evolution, these new quality diversity (QD) algorithms are particularly well-suited to evolution's inherent strengths, thereby offering a promising niche for EC within the broader field of machine learning. However, because QD algorithms are so new, until now no comprehensive study has yet attempted to systematically elucidate their relative strengths and weaknesses under different conditions. Taking a first step in this direction, this paper introduces a new benchmark domain designed specifically to compare and contrast QD algorithms. It then shows how the degree of alignment between the measure of quality and the behavior characterization (which is an essential component of all QD algorithms to date) impacts the ultimate performance of different such algorithms. The hope is that this initial study will help to stimulate interest in QD and begin to unify the disparate ideas in the area.
Hyperbaric oxygen in carbon monoxide poisoning. (1969)

JORA 53 intense loneliness, having never been without a dog before.I am now hopeful she may now change her mind, at least to* the extent of a Siamese cat, and that this may eventually permit corticosteroids to be tailed-off without relapse of her arteritis in one of its more unpleasant guises.This happened to a patient from the same practice only a few months back who stopped taking her prednisone, prescribed for her temporal arteritis, because the doctor emigrated.Her cardiac infarction, at first thought unremarkable, was followed by pericarditis and mental confusion, both of which, like her previous temporal arteritis, responded at once to prednisone.
A microstrip-based unit cell for quasi-optical amplifier arrays (1993)

A microwave scale model of an amplifying element suitable for millimeter-wave quasi-optical arrays is presented. Power is guided into the amplifier by short sections of waveguide and then fed into a microstrip based MESFET amplifier with an E-field probe. A second E-field probe couples the output signal into a similar waveguide feed on the back-side of the element. The output waveguide is orthogonal to the input to achieve isolation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Towards a theory of software protection (1987)

The large submetacentric abnormal late replicating X-chromosomes were found in three patients under karyological studies of 168 patients with Turner's syndrome. G- and C-banding revealed that abnormal chromosomes are three variants of isodicentric chromosomes resulting from the junction of the short arms of two X-chromosomes. The patients' karyotypes are respectively: 45,X/46,X,dic (X)(qter leads to p22: :p22 leads to qter); 46X,dic(X)(qter leads to p21: :p21 leads to qter); 46,X/46,X,dic(X)(qter leads to p11: :p11 leads to qter). All the three patients had different size deficiencies of the short arm of the X-chromosome. Partial X-monosomy caused the appearance of features of the Turner syndrome, which was less expressed in our patients compared to those with the entire X-monosomy.
Accumulation of lipids, proteins, alkaloids and anthocyanins during embryo development in vivo of<i>Theobroma cacao</i> L. (1982)

Abstract Developing embryos of Theobroma cacao ranging in weight from 0.01–2.2 g dry weight, equivalent to 100–180 days postpollination, were analyzed for lipids, alkaloids, proteins, and anthocyanins. Total lipid, fatty acid, triglyceride, alkaloid, and anthocyanin accumulation increased linearly after an initial lag with embryo dry weight. Palmitic, stearic, arachidic, and oleic acids had constant rates of accumulation per micromole of total fatty acid (0.29, 0.27, 0.38, and 0.01, respectively); however, linoleic and linolenic acid accumulation decreased from 0.2 and 0.02 below 0.2 g dry weight to 0.035 and 0.0035 above 0.2 g dry weight, respectively. Monounsaturated triglycerides [palmito‐oleo‐stearin (POS), oleo‐distearin (SOS), and oleo‐dipalmitin (POP)] continued to accumulate as dry weight increased but polyunsaturated triglycerides [palmito‐diolein (POO), stearo‐diolein (SOO), linoleo‐dipalmitin (PLP), and palmito‐linoleo‐olein (PLO)] ceased to accumulate at about 0.4 g dry weight. Theobromine accumulation increased linearly with dry weight after an initial lag but the rate differed with cultivar. Caffeine accumulation was low until the final stages of development. The protein pattern became dominated by 4 protein species with apparent molecular weights of 43, 34, 22, and 14 kDa as embryos matured.
Iodide in CTAB Prevents Gold Nanorod Formation (2009)

The gold nanocrystal seed-mediated approach using cetyltrimethylammonium bromide (CTAB) as a stabilizing surfactant is commonly used to make large quantities of monodisperse gold nanorods. This method, however, has been at times difficult to reproduce in different laboratories. We recently showed [Smith, D. K.; Korgel, B. A. Langmuir 2008, 24, 644-649] that a very low concentration impurity in CTAB obtained from some suppliers prevents nanorod growth but were not able to identify the impurity. Here, we report that the impurity is iodide. Inductively coupled plasma mass spectroscopy (ICP-MS) revealed that iodide concentrations vary in CTAB from different suppliers, from less than 2.75 ppm up to 840 ppm. When CTAB with iodide concentrations greater than 50 ppm is used, nanorods do not form and the product consists entirely of spherical nanocrystals. Iodide slows the reduction of Au(III) to Au0. Iodide adsorption on Au {111} surfaces inhibits nanorod growth.
[Signal and data acquisition based on waveform graph]. (2001)

It is well known that signal acquisition is the first step in signal processing. A simple and convenient method of acquiring biologic data is described here, which needs no special acquisition equipment, and is practical and makes the data acquisition more credible.
Performance study of a 10-wavelength DFB laser array with integrated electroabsorption modulators (2002)

We report the performance of the 10-wavelength DFB laser array with small wavelength dependence of output power, extinction ratio, frequency response and chirp parameter. The active layer consists of six strain compensated quantum wells grown on top of the modulator waveguide layer. Over a wavelength span of 15 nm, the average power into a single mode fiber varies from -3 to 0 dBm (@80 mA), with better than -12 dB (@2 V) extinction ratio, a bandwidth of 5 GHz and chirp parameter less than 1.
PREPARATION OF HIGH QUALITY HOLLOW POLYMER MICROSHELL (2000)

Density matched microencapsulation technique has been developed for production of high quality hollow polymer microshells employed in inertial confinement fusion(ICF) experiments.Concentricity and sphericity of the microshell prepared by the technique are typically more than 98% and 99% respectively.Vacuole in the wall of the microshells has been greatly reduced by precise filtering of shell making soultion.To meet the need of larger microshells in the future ICF experiments,the micoshells with diameter above 500μm have been produced by reduction of emulsion agitate rate.
Mutational Inactivation of PTPRD in Glioblastoma Multiforme and Malignant Melanoma (2008)

An additional tumor suppressor gene on chromosome 9p telomeric to the CDKN2A/B locus has long been postulated to exist. Using Affymetrix 250K single nucleotide polymorphism arrays to screen for copy number changes in glioblastoma multiforme (GBM), we detected a high frequency of deletions of the PTPRD gene, which encodes a receptor protein tyrosine phosphatase at chromosome 9p23-24.1. Missense and nonsense mutations of PTPRD were identified in a subset of the samples lacking deletions, including an inherited mutation with somatic loss of the wild-type allele. We then sequenced the gene in melanoma and identified 10 somatic mutations in 7 of 57 tumors (12%). Reconstitution of PTPRD expression in GBM and melanoma cells harboring deletions or mutations led to growth suppression and apoptosis that was alleviated by both the somatic and constitutional mutations. These data implicate PTPRD in the pathogenesis of tumors of neuroectodermal origin and, when taken together with other recent reports of PTPRD mutations in adenocarcinoma of the colon and lung, suggest that PTPRD may be one of a select group of tumor suppressor genes that are inactivated in a wide range of common human tumor types.

CONCENTRATIONS OF CYCLIC AMP IN RABBIT OVARIAN TISSUE DURING THE PREOVULATORY PERIOD AND PSEUDOPREGNANCY AFTER INDUCTION OF OVULATION BY ADMINISTRATION OF HUMAN CHORIONIC GONADOTROPHIN (1975)

Concentrations of cyclic AMP were measured in rabbit ovaries at various times after injection of an ovulatory dose of human chorionic gonadotrophin (HCG). A biphasic increase in cyclic AMP concentration occurred during the preovulatory period, with peaks 30 min and 3-4 h after HCG injection. Concentrations of cyclic AMP had returned to those observed in ovaries of control oestrous animals before the onset of ovulation 10-12 h after administration of HCG, and remained low throughout the period of pseudopregnancy. Concentrations of cyclic AMP in the newly formed and developing corpora lutea were similar to the concentrations observed in the remainder of the tissue during this period. No significant increase in cyclic AMP concentration was observed 7-9 days after initiation of ovulation. Concentrations of ATP were also investigated during the preovulatory period. The dose-response relationship of HCG to cyclic AMP production in oestrous rabbit ovaries was investigated.
Determining the optimal dose of atrasentan by evaluating the exposure‐response relationships of albuminuria and bodyweight (2018)

This study aimed to identify the optimal dose of the endothelin-1 receptor antagonist atrasentan with maximal albuminuria reduction and minimal signs of sodium retention, as manifested by increase in bodyweight. Data from the RADAR-JAPAN studies were used, evaluating the effect of 0.75 or 1.25 mg/d of atrasentan in 161 patients with type 2 diabetes and kidney disease. Individual pharmacokinetic parameters were estimated using a population pharmacokinetic approach. Subsequently, changes in the urinary albumin-to-creatinine ratio (UACR) and bodyweight from baseline after 2 weeks' exposure were modelled as a function of the pharmacokinetic parameters. The 0.75 and 1.25 mg doses showed a mean UACR reduction of 34.0% and 40.1%, whereas mean bodyweight increased by 0.9 and 1.1 kg, respectively. A large variation between individuals was observed in the UACR and bodyweight responses. Individual pharmacokinetic parameters correlated significantly with both individual UACR and bodyweight responses (P < .01). The individual response curves for UACR and bodyweight crossed at approximately the mean trough concentration of 0.75 mg atrasentan, indicating that 0.75 mg/d of atrasentan is the optimal dose for kidney protection with maximal efficacy (albuminuria reduction) and safety (minimal sodium retention).
Inhibition of ribonucleoside diphosphate reductase by hydroxyurea. (1968)

Hydroxyurea, a compound which inhibits the growth of rapidly proliferating tissues in animals and man, is known to inhibit DNA synthesis, and studies in crude systems have indicated that it does so by preventing the reduction of ribonucleotides to deoxyribonucleotides.

This study demonstrates hydroxyurea-induced inhibition of the reduction of ribonucleotides by a highly purified enzyme system from Escherichia coli B. The inhibition (70% at 3 × 10-3 m under standard incubation conditions) is dependent on the concentration of hydroxyurea and on the duration of exposure of the enzyme to hydroxyurea. The effect of hydroxyurea is specific for protein B2 of the ribonucleoside diphosphate reductase system. The inhibition of enzymatic activity is apparently irreversible, although there is negligible irreversible binding of 14C-labeled hydroxyurea to the enzyme protein.
A Novel Flow Bioreactor for <i>In Vitro</i> Microvascularization (2010)

Although the importance of fluid flow for proper vascular development and function in vivo is well recognized, microvascular formation in response to flow has not been well evaluated in a three-dimensional (3D) environment in vitro. In this study, we developed a novel 3D in vitro perfusion system that allows direct investigation of the effects of shear stress on the development of microvasculature in vitro. This system utilizes a 3D collagen gel for suspension of vascular cells and mesenchymal stem cells, through which flow is directly perfused. We characterized the flow conditions and demonstrate the impact of flow on the development of microvasculature using a coculture of endothelial cells and mesenchymal stem cells. With the unique ability to apply bulk flow through the collagen gels, and to estimate shear stress within the constructs, this perfusion system provides a flexible platform for developing a controllable biomimetic environment that can be adapted for a variety of investigations of microvascularization.
A new bit synchronization method for a GPS receiver (2003)

We develop a maximum-likelihood bit synchronization algorithm. This algorithm computes an estimate of the bit energy for all possible bit boundary candidates and chooses that candidate which maximizes the energy. Means to estimate whether the received signal contains enough bit value changes are also presented. The effect of frequency error is analyzed. It is shown that small frequency errors can be tolerated. Furthermore, a way to deal with larger errors is developed. Computer simulations show that the new algorithm is efficient in handling a very weak received signal.
MARC: Adaptive Rate Control scheme for improving the QoE of streaming services in mobile broadband networks (2010)

Recently, due to the prevalence of various mobile devices and broadband wireless networks, there has been a significant increase in interest and demand for multimedia streaming services such as the mobile IPTV. In order to deploy a mobile IPTV service in wireless broadband networks, offering users efficient wireless resource utilization and seamlessly offering Quality of Experience (QoE) are important issues. In this paper, we propose a new adaptive streaming scheme, called Mobile-aware Adaptive Rate Control (MARC), which adjusts the quality of bit-stream and transmission rate of video streaming based on the wireless channel status and network status. The proposed scheme can provide a seamless multimedia playback service in wireless broadband networks in addition to improving the quality of service (QoS) of multimedia streaming services. The proposed MARC scheme alleviates the discontinuity of multimedia playback and allocates a suitable client buffer to the wireless broadband network. The simulation results demonstrate the effectiveness of our proposed scheme.
Biological control of the two-spotted spider mite in raspberries with the predator mite, Phytoseiulus persimilis (1994)

Phytoseiuius persimilis was released to control the two-spotted spider mite, Tetranychus urticae, in field raspberries at Agassiz, B.C. The mite predators became established and responded numerically to the prey in the treatment plots. For a period of 8 weeks after release, the numbers of T. urticae were consistently lower in the treatment plots than in the controls. Differences in numbers of T. urticae between the treatments and the controls were significant on two dates. Key words: Tetranychus urticae; Phytoseiulus persimilis; Rubus idaeus; biological control; Fraser Valley
