TRANSMISSION OF MANNHEIMIA HAEMOLYTICA FROM DOMESTIC SHEEP (OVIS ARIES) TO BIGHORN SHEEP (OVIS CANADENSIS): UNEQUIVOCAL DEMONSTRATION WITH GREEN FLUORESCENT PROTEIN-TAGGED ORGANISMS (2010)

Previous studies demonstrated that bighorn sheep (Ovis canadensis) died of pneumonia when commingled with domestic sheep (Ovis aries) but did not conclusively prove that the responsible pathogens were transmitted from domestic to bighorn sheep. The objective of this study was to determine, unambiguously, whether Mannheimia haemolytica can be transmitted from domestic to bighorn sheep when they commingle. Four isolates of M. haemolytica were obtained from the pharynx of two of four domestic sheep and tagged with a plasmid carrying the genes for green fluorescent protein (GFP) and ampicillin resistance (AP(R)). Four domestic sheep, colonized with the tagged bacteria, were kept about 10 m apart from four bighorn sheep for 1 mo with no clinical signs of pneumonia observed in the bighorn sheep during that period. The domestic and bighorn sheep were then allowed to have fence-line contact for 2 mo. During that period, three bighorn sheep acquired the tagged bacteria from the domestic sheep. At the end of the 2 mo of fence-line contact, the animals were allowed to commingle. All four bighorn sheep died 2 days to 9 days following commingling. The lungs from all four bighorn sheep showed gross and histopathologic lesions characteristic of M. haemolytica pneumonia. Tagged M. haemolytica were isolated from all four bighorn sheep, as confirmed by growth in ampicillin-containing culture medium, PCR-amplification of genes encoding GFP and Ap(R), and immunofluorescent staining of GFP. These results unequivocally demonstrate transmission of M. haemolytica from domestic to bighorn sheep, resulting in pneumonia and death of bighorn sheep.
Human Papillomavirus Involvement in Esophageal Carcinogenesis in the High-Incidence Area of China: A Study of 700 Cases by Screening and Type-Specific in Situ Hybridization (2000)

This study reports the largest series of esophageal cancers ever analyzed for the presence of HPV DNA. Our results confirm the presence of common mucosal HPV types in esophageal carcinomas but also suggest the involvement of other (novel?) HPV types that are unusually detected in genital cancers in a significant proportion of these lesions. The results further indicate that HVP has an etiologic role in esophageal carcinogenesis, at least in the high-incidence area of northern China.

A 4–8 GHz dual gate m.e.s.f.e.t. amplifier (1978)

A two-stage dual-gate f.e.t. amplifier with small signal gain of 20 ± 0.75 dB, covering an octave bandwidth (4–8 GHz) and having a dynamic gain control range in excess of 60 dB is reported. The gain frequency response, input and output v.s.w.r. are described as a function of second-gate voltage. The performance of the dual-gate f.e.t. amplifier as a fast r.f. switch is also presented.
Self-Organizing Learning Array (2005)

A new machine learning concept--self-organizing learning array (SOLAR)--is presented. It is a sparsely connected, information theory-based learning machine, with a multilayer structure. It has reconfigurable processing units (neurons) and an evolvable system structure, which makes it an adaptive classification system for a variety of machine learning problems. Its multilayer structure can handle complex problems. Based on the entropy estimation, information theory-based learning is performed locally at each neuron. Neural parameters and connections that correspond to minimum entropy are adaptively set for each neuron. By choosing connections for each neuron, the system sets up its wiring and completes its self-organization. SOLAR classifies input data based on the weighted statistical information from all the neurons. The system classification ability has been simulated and experiments were conducted using test-bench data. Results show a very good performance compared to other classification methods. An important advantage of this structure is its scalability to a large system and ease of hardware implementation on regular arrays of cells.
Broadband infrared emission from Er–Tm:Al2O3 thin films (2005)

Thin films of amorphous aluminum oxide (Al2O3) co-doped with Er3+ and Tm3+ have been synthesized by alternate pulsed laser deposition. When pumped at 794 nm a broad emission band over 1400–1700 nm is observed. Two peaks related to the 1540 nm band from Er3+ and to the 1640 nm band from Tm3+ are clearly distinguished. The photoluminescence intensity ratio of the 1640–1540 nm emissions has been controlled by modifying the Tm concentration. A spectrum with a fairly flat profile and a full width at half maximum of 230 nm is obtained for an Er concentration of 7.2×1019cm−3 and a [Tm]∕[Er] concentration ratio of 3. It is found that the Er3+ to Tm3+ energy transfer processes play an important role in the definition of the luminescent response. The large width of the emission band and the excellent optical and thermomechanical properties of the Er–Tm co-doped Al2O3 signal this system as a potential candidate for the development of broadband integrated optical amplifiers.
Volume reconstruction from sparse 3D ultrasonography (2003)

3D freehand ultrasound has extensive application for organ volume measurement and has been shown to have better reproducibility than estimates of volume made from 2D measurement followed by interpolation to 3D. One key advantage of free-hand ultrasound is that of image compounding, but this advantage is lost in many automated reconstruction systems. A novel method is presented for the automated segmentation and surface reconstruction of organs from sparse 3D ultrasound data. Preliminary results are demonstrated for simulated data, and two cases of in-vivo data; breast ultrasound and imaging of ovarian follicles.

Trace organic compounds in aircraft turbine combustor exhaust were determined as functions of fuel type and engine operating pressure (power setting). Hydrocarbons were collected by multistage cryogenic sampling. Chemicals were analyzed by a coupled gas chromatograph-mass spectrometer-data system. Results are presented in the context of assessment of biomedical impact of aircraft operations. (Author)
Quantized conductance of magnetoelectric subbands in ballistic point contacts (1988)

The two-terminal conductance of ballistic point contacts in the two-dimensional electron gas of a high-mobility $\frac{\mathrm{GaAs}}{{\mathrm{Al}}_{x}{\mathrm{Ga}}_{1\ensuremath{-}x}\mathrm{As}}$ heterostructure has been studied in quantizing electric and magnetic fields. The conductance is found to be quantized at multiples of $\frac{{e}^{2}}{h}$, exclusively determined by the number of occupied magnetoelectric subbands in the constriction. The experiment provides the first direct demonstration of magnetic and electric depopulation of one-dimensional subbands in a single wire.
Pervasive enablement of business processes (2004)

People are an important part of many business processes. Current workflow-based implementations of business processes constrain users to the desktop environment; require them to periodically check for pending tasks; and do not support direct or synchronous people-to-people interaction. On the other hand, the wide spectrum of people collaboration tools ranging from telephones to instant messaging and to email have no provision for structured collaboration and are separate from business processes. We have designed and implemented a system, dubbed PerCollab that integrates workflow and collaboration technologies. It allows people to participate in business processes from anywhere using a traditional collaboration mechanism. It proactively engages users in business processes by pushing interaction to a convenient device of the users. PerCollab uses an extended BPEL to formally define business processes with human partners and exploits dynamic user context to solve the personal mobility problem. Our prototype implementation integrates a variety of collaboration tools: instant messaging, email and e-meeting.
Imaging that exploits multipath scattering from point scatterers (2005)

This paper develops a method for making an image of an object when there are extra point-like scatterers in the environment. Once the location of these scatterers is known, they can be exploited in the imaging process. Here the extra point scatterers are assumed to lie between the sensor and the object of interest. A single-scattering model is used for the object itself. Detailed analysis is carried out for the case of a single extra scatterer in the foreground; the extension to the case of many scatterers is expected to be similar.
Software development and configuration management in the Cronus distributed operating system (1988)

A description is given of the authors experience with software development and configuration management during the development and use of the Cronus distributed operating system. Cronus establishes a computing environment in which it is possible to perform software development for a heterogeneous set of computers, issue periodic software upgrades for each supported type of computer, and provide support for the software after upgrades have been installed. The author has designed a software source control system to manage the introduction of new versions of software modules and have established a configuration management plan to control the distribution of software to the varied set of supported computer types through a master-host-relay-host-destination-host approach. In discussing release support, the author pays special attention to the bug report manager, a distributed Cronus service designed to manage reports of problems in the Cronus system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Development and implementation of a miniature RFID system in a shopping mall environment (2019)

<p>The advancement of technology has brought about the need for industrial innovation. One area where innovation is required in a developing country is in the retail industry (this is the focus point of this project) where the present system that is the barcode technology is old and archaic. This project is based on the use of Radio Frequency Identification (RFID) technology to create a faster, easier and more secured checkout system. This paper showcases the development of a miniature RFID desktop application that can be used for registering items coming into a shopping mall, checking out of goods bought from the shopping mall and the detection of an attempt to steal goods from the shopping mall, using both C# programming language and MySQL for the database management.</p>
Icosahedral phase formation in Ti<sub>68-x</sub>Cr<sub>32</sub>Si<sub>x</sub>alloys (1990)

Abstract We report, for the first time, the formation of the icosahedral phase (i-phase) in rapidly quenched Ti68-xCr32Six alloys, where 69 ≤ x ≤ 18. The i-phase occurs at a composition for which there are no structurally similar crystalline phases. Transmission electron microscopy (TEM) and X-ray diffraction measurements are presented. The TEM diffraction patterns show strong localized diffuse scattering and spot anisotropy. These features are compared with similar ones found in Al83Cr17 and Ti61Mn37Si2 icosahedral phases. No evidence for an enthalpic signature of phase transformation was found upon heating to the melting temperature, indicating that the i-phase is at least strongly metastable. The first estimates of the density are reported.
A novel technique for the determination of the radiation patterns of medium gain antennas from scalar intensity measurements (2003)

This work described a technique whereby indirect holography can be extended to enable the radiation patterns of medium gain antennas to be obtained in a simple and inexpensive manner. It has described a method which overcomes the limitations imposed by using a traditional radiated reference signal. This has been achieved by sampling at spacing much less than half wavelength and electronically introducing a phase shift between each sample. The resultant separation of Fourier transform terms enables the far field radiation pattern to be determined. This has been supported by simulation results for a small antenna which demonstrate the improvement available using this technique. It has also demonstrated that this technique can also be applied to the reconstruction of complex fields at any desired distance from the antenna. This has included the reconstruction of antenna aperture fields which show good agreement with the original aperture fields.
Nasal polyps: medical or surgical management? (1996)

Nasal polyposis is considered to be a non-IgE-mediated inflammatory condition of the nose and sinuses, often associated with chronic non-allergic rhinitis, aspirin intolerance and non-allergic asthma. The aetiology of nasal polyposis is unknown. The main symptoms are nasal obstruction and disturbance of the sense of smell. Occlusion of the nasal passage by a few large polyps could be treated by simple polypectomy to help the patient breathe through the nose. Polypectomy per se does not worsen asthma. Other surgical procedures can be performed, depending on the degree of the disease. The aim of surgery is to restore the physiological properties of the nose by making the nose as free from polyps as possible, and to allow drainage of infected sinuses. Complementary medical treatment of polyposis is always necessary, as surgery cannot treat the inflammatory component of the mucosal disease. In this respect, topical corticosteroids have long been the drugs of choice to reduce the size of polyps, to prevent recurrence after surgery, and are often the main treatment for the disease in many patients. Fluticasone propionate has now been shown to be at least as effective as beclomethasone dipropionate as a medical tool in the management of polyposis. Short-term treatment with systemic corticosteroids is an alternative method of inducing remission and controlling nasal polyps. However, in most patients with nasal polyps, treatment consists of both medical and surgical management.
The Anatomy of the Epigastric Flap in the Experimental Rat (1984)

In order to explain the variability noted in the fluorescein staining characteristics of the epigastric axial flap in the experimental laboratory rat, the anatomy of the blood supply of this particular flap was investigated. In 10 rats, the vascular pattern of the superficial epigastric trunk to the abdominal skin was found to be similar. A small branch of the trunk extended toward the medial abdominal skin to collateralize with a branch of the internal mammary vessel entering from the chest skin. A large extension of the superficial epigastric trunk extended laterally toward the midlateral point of the animal and cephalad to collateralize with the vessels in the lateral chest wall, presumably the lateral thoracic artery. Fluorescein staining characteristics of 10 flaps including or excluding the lateral branch were examined, and a significant difference was found in the immediate fluorescein staining characteristics. The flaps that included the lateral branch fluoresced to an average of 89.2 percent of the flap length, and those in which the lateral branch was excluded fluoresced to 68.7 percent of the flap length. The use of this flap model in experimental flap research should include a precise description of the anatomy of the particular flap used in order to ensure reproducible results.
Simple Solar Spectral Model for Direct and Diffuse Irradiance on Horizontal and Tilted Planes at the Earth's Surface for Cloudless Atmospheres (1986)

In a previous work, we described a simple model for calculating direct normal and diffuse horizontal spectral solar irradiance for cloudless sky conditions. In this paper, we present a new simple model (SPCTRAL2) that incorporates improvements to the simple model approach and an algorithm for calculating spectral irradiance on tilted surfaces. The model was developed using comparisons with rigorous radiative transfer codes and limited outdoor measurements. SPCTRAL2 produces terrestrial spectra between 0.3 and 4.0 μm with a resolution of approximately 10 nm. Inputs to the model include the solar zenith angle, the collector tilt angle, atmospheric turbidity, the amount of precipitable water vapor and ozone, surface pressure, and ground albedo. A major goal of this work is to provide researchers with the capability to calculate spectral irradiance for different atmospheric conditions and different solar collector geometries using microcomputers.
Construction and analysis of<i>luxCDABE</i>-based plasmid sensors for investigating<i>N</i>-acyl homoserine lactone-mediated quorum sensing (1998)

Plasmid reporter vectors have been constructed which respond to activation of LuxR and its homologues LasR and RhlR (VsmR) by N-acyl homoserine lactones (AHLs). The expression of luxCDABE from transcriptional fusions to PluxI, PlasI and PrhlI respectively, occurs in the presence of activating AHLs. A profile of structure/activity relationships is seen where the natural ligand is most potent. The characterisation of individual LuxR homologue/AHL combinations allows a comprehensive evaluation of quorum sensing signals from a test organism.
A 3.3-V single-poly CMOS audio ADC delta-sigma modulator with 98-dB peak SINAD and 105-dB peak SFDR (2000)

This paper presents a second-order /spl Delta//spl Sigma/ modulator for audio-band analog-to-digital conversion implemented in a 3.3-V, 0.5-/spl mu/m, single-poly CMOS process using metal-metal capacitors that achieves 98-dB peak signal-to-noise-and-distortion ratio and 105-dB peak spurious-free dynamic range. The design uses a low-complexity, first-order mismatch shaping 33-level digital-to-analog converter and a 33-level flash analog-to-digital converter with digital common-mode rejection and dynamic element matching of comparator offsets. These signal-processing innovations, combined with established circuit techniques, enable state-of-the art performance in CMOS technology optimized for digital circuits.
Micro electrostatic wobble motor with toothed electrodes (2002)

A micro electrostatic wobble motor with toothed electrodes has been designed using a newly proposed tooth profile, which we call the "composite profile". This new design results from considering the profile of the non-contact area, on which the generated electrostatic torque depends. The new tooth profile eliminates slip between stator and rotor, so complete wobble motions are achieved even when a large load is applied. A micro wobble motor based on this design was fabricated by micro-wire electrical discharge machining. The motor is 6 mm in gear pitch diameter and 3 mm in thickness. The module of the teeth is 0.063, and the tooth numbers of the stator and rotor are 96 and 95, respectively. Experimental results show that the stall torque was about 0.015 mNm with a 350 V supply and the motor maintained an almost constant speed and full wobble motion until just before stalling. We conclude that toothed electrodes with the proposed profile are a very effective way to achieve complete wobble motion even when a large load is applied.
Inhibitory effects of protocatechuic acid on the post-initiation phase of hamster pancreatic carcinogenesis induced by N-nitrosobis(2-oxopropyl)amine. (2001)

The chemopreventive effects of protocatechuic acid (PCA) were investigated during the post-initiation stage of the N-nitrosobis(2-oxopropyl)amine (BOP)-initiated hamster pancreatic tumorigenesis model. Female 5-week-old hamsters were divided into 6 groups. Animals in groups 1-3, each consisting of 30 hamsters, were given two s.c. injections of 20 mg/kg body weight of BOP with a one week interval as an initiation treatment. After the BOP injection, hamsters in groups 1 and 2 were respectively fed diet supplemented with 1000 or 500 ppm of PCA for 49 weeks. The animals in group 3 were treated with BOP alone. The animals in groups 4-6, each consisting of 10 hamsters, were given 1000 or 500 ppm PCA, or basal diet alone without prior BOP injection. At the termination of experimental week 52, the incidences and multiplicities of neoplastic lesions in the pancreas were comparable among the BOP-treated groups. However, the incidence of pancreatic tumors larger than 3 cm was significantly lower in the PCA-treated high dose groups than in the control group (p < 0.05). Moreover the incidence of advanced pancreatic cancers which had directly invaded adjacent tissues such as the diaphragm, spleen and stomach was reduced by the PCA treatments, being significantly (p < 0.01) lower in group 2 than in group 3. Our results thus indicated that PCA can inhibit the late post-initiation or progression phase of BOP-induced pancreatic carcinogenesis in hamsters.
Renal dopamine excretion in healthy volunteers after oral ingestion of<scp>l</scp>‐Dopa (1993)

L-Dopa is converted to dopamine by aromatic-L-amino acid decarboxylase (AADC). In the kidney, proximal tubular epithelial cells are rich in AADC and urinary free dopamine excretion is a marker for endorenal extraneuronal dopamine synthesis. The urinary free dopamine excretion was analysed in a double-blind cross-over study after oral ingestion of L-Dopa or a placebo in five healthy volunteers. The drug ingestions were separated by one week's wash-out. Since in a preliminary study, two volunteers ingesting a single L-Dopa dose of 500 mg with breakfast experienced nausea, the five volunteers of the present study were given 300 mg L-Dopa (50 mg at 9 am with breakfast, 100 mg before lunch and 150 mg before dinner) without any adverse effects. L-Dopa induced an increase in 24-h urinary dopamine excretion (HPLC with electrochemical detection). Free urinary dopamine (1900 micrograms/24 h) accounted for 0.8% of the daily oral L-Dopa dose and represented 10% of total urinary dopamine excretion. L-Dopa treatment had no significant effect on mean ambulatory arterial blood pressure and heart rate measured from 9 am to 6 pm (Spacelabs) or on 24 h urinary water and sodium excretion.
