Cardiac evaluation from radioisotope dynamics. (1972)

Summary A method for radioisotope angiocardiography using the scintillation camera and a quantitative television data system for rapid data recording and readout is described. This essentially noninvasive, risk-free, outpatient procedure, which can be repeated at frequent intervals, shows promise of being a significant supplement to conventional x-ray angiocardiography. By precise area-of-interest masking and the use of fast-response counting-rate recording, a stroke-by-stroke reading of the left ventricular ejection fraction is obtained. Cardiac output is determined from the same record. In the absence of valvular insufficiency, end-diastolic volume is computed from these numbers. Comparison of this value with end-diastolic volume determined from area of measurements of the pictures provides an estimate of the degree of regurgitation when present. Direct comparison of this technique with standard contrast angiocardiography has been made in 16 patients with confirmatory results which are presented. Clinical application has already demonstrated the ability of isotope cardiography to provide a large amount of information not obtainable by other simple techniques. It is likely that this method will also prove useful in situations requiring serial study such as the management of intensive-care cardiac patients.

Aromatic Fumaronitrile Core-Based Donor−Linker−Acceptor−Linker−Donor (D-π-A-π-D) Compounds: Synthesis and Photophysical Properties (2010)

A new class of aromatic fumaronitrile core-based compounds with different donors and linkers has been synthesized and well characterized. Compounds 1 and 2 have indole and 2-phenylindole groups as electron donors, respectively. Compounds 3 and 4 have a diphenylamino group as the electron donor, and compound 5 has a 3,6-di-tert-butylcarbazole group as an electron donor. These compounds absorb in the blue-to-green region and emit in the blue-to-red region depending on the electron donor, linker, and solvents. The quantum yields of fluorescence of these compounds in solution are measured and found to be moderate, but in solid states, they are high. These compounds display strong emission solvatochromism that is reflected by a large shift in their fluorescence emission maxima on changing the solvents. This change is accompanied by a successive decrease in fluorescence intensity. The fluorescence lifetimes of these compounds are measured in different solvent and found to vary from <1 to 7 ns. Optical switching of these compounds with solvents, concentration, and excitation energy have been studied. The correlation between the functional group and optical properties has been established to some extent. The ability of these compounds to function as colorimetric and luminescence pH sensors is demonstrated with color changes and luminescence switching upon the addition of trifluoroacetic acid. The potentiality of these compounds for application in optoelectronics has been optically assessed.
Guarded tone signalling (1960)

A method of audio frequency tone signalling which utilizes the maximum number of combinations of a given number of tone channels is described. The principle feature of this method is the use of all tones present as a positive space. Several typical applications of this method to selective calling are described. These include selective party-line telephone ringing, and aircraft selective call.

Predictors of Bone Mass in Perimenopausal Women (1990)

Risk factors for osteoporosis are of limited use in identifying women with low bone mass around the time of menopause. Measurements of bone mass are probably necessary if the risk for osteoporosis is to be the basis for deciding on estrogen replacement therapy.
Functions and expression of Txk, a non receptor tyrosine kinase of the Tec family (2003)

Imbalance of Th1/Th2 responses is associated with the development of human autoimmune diseases and allergic diseases. We have studied a role of Txk, a member of Tec family non-receptor tyrosine kinase for the Th1/Th2 cell development.We found that Txk is expressed Th1/Th0 cells with IFN-γ producing potential. Txk transfection leads to severalfold increase in IFN-γ production; neither IL-2 nor IL-4 production were affected. Thus, Txk acts as a Th1 cell specific transcription factor.Furthermore, we found that Txk expression is enhanced by Th1 cytokines but is inhibited by Th2 cytokines. Txk expression of the peripheral blood T cells is decreased in patients with allergic diseases. Collectively, Txk expression is modulated by with Th1/Th2 cytokines and is importantly involved in immune aberration in patients with immunological disorders. These results suggest that Txk is a possible therapeutic target of the diseases with Th1/Th2 imbalance.
e0601 Effects of BMI on ischaemic stroke in hospital patients with essential hypertension (2010)

<h3>Objective</h3> To investigate the association between BMI and the incidence of ischaemic stroke in essential hypertensive (EH) patients. <h3>Methods</h3> A total of 2158 EH patients were divided into EH without ischaemic stroke group and EH with ischaemic stroke group. Four BMI quartiles were defined based on BMI level (The first quartile: BMI ≤22.68 kg/m<sup>2</sup>, n=540; The second quartile: BMI 22.69–24.82 kg/m<sup>2</sup>, n=538; The third quartile: BMI 24.83–26.84 kg/m<sup>2</sup>, n=541; The fourth quartile: BMI ≥26.85 kg/m<sup>2</sup>, n=539). The incidence of ischaemic stroke in four BMI levels was evaluated by multivariable logistic regression analyses. <h3>Results</h3> (1) The average BMI in EH with ischaemic stroke group is lower than that in EH without ischaemic stroke group (24.36±3.21 vs 25.15±3.31kg/m<sup>2</sup>, p<0.001). (2) Form the first quartile to fourth quartile of BMI, the incidence of ischaemic stroke were decreasing (37.6%, 34.8%, 30.9%, 23.0%, p<0.001). With 6.2% (95% CI 3.3% to 9.0%) decreased risk of incidence ischaemic stroke per 1 kg/m<sup>2</sup> increase of BMI. (3) Compared with the lowest BMI group, the adjusted OR (aOR) for ischaemic stroke in the highest BMI group was significantly lower (aOR: 0.800, 95% CI: 0.730 to 0.875, p<0.001). (4) In male group, comparing with the lowest BMI group, the aOR for ischaemic stroke in the highest BMI group was significantly lower (aOR: 0.811, 95% CI: 0.717 to 0.918, p=0.001); Similar trend was found in female group (aOR: 0.776, 95% CI: 0.678 to 0.889, p<0.001). <h3>Conclusion</h3> Lower BMI was associated with increased incidence of ischaemic stroke in EH patients.
Research on Automatic Detection Technique for Pebrine Image Based on Computer Vision (2010)

Aiming to achieve the automatic detection and accurate identification of pebrine images, the fuzzy contrast enhancement algorithm was utilized to enhance the contrast of the target image in order to improve the image’s quality; Owing to the color character of light green for the pebrine, the image segmentation technique based on the HSI model can be applied to extract the pebeine image, at the same time, the morphology theory can be adopted to remove the noises such as the hole noise and point noise, and to separate the bond particles; The region labeling can be done on the binary image after the image segmentation, then the shape parameters of pebrine can be extracted, by making full use of the feature parameters, the method of neural network based on genetic algorithm is applied to recognize the pebrine image. These experiments show that the method has achieved satisfactory image recognition results.
Optical pattern recognition using circular harmonic expansion (1982)

Presented in this paper is an optical implementation of a shift- and rotation-invariant pattern recognition technique. A computer-generated hologram is designed to match with one of the circular harmonic components of the target. Experimental results with simple photographic objects show that targets with different locations and orientations can be simultaneously recognized by the optical system.
Multiresolution scanning imager with spatially uniform noise response based on a new class of Hadamard masks (2000)

In spite the prodigious growth in the market for digital cameras, they have yet to displace film-based cameras in the consumer market. This is largely due to the high cost of photographic resolution sensors. One possible approach to producing a low cost, high resolution sensor is to linearly scan a masked low resolution sensor. Masking of the sensor elements allows transform domain imaging. Multiple displaced exposures of such a masked sensor permits the device to acquire a linear transform of a higher resolution representation of the image than that defined by the sensor element dimensions. Various approaches have been developed in the past along these lines, but they often suffer from poor sensitivity, difficulty in being adapted to a 2D sensor or spatially variable noise response. This paper presents an approach based on a new class of Hadamard masks--Uniform Noise Hadamard Masks--which has superior sensitivity to simple sampling approaches and retains the multiresolution capabilities of certain Hadamard matrices, while overcoming the non-uniform noise response problems of some simple Hadamard based masks.
Herstellung und Zurichtung von MgAl‐Spinell‐Substraten für die Halbleiterepitaxie (1975)

Abstract Es werden einige Verfahren zur Herstellung von einkristallinen MgAl‐Spinell‐Substraten für die Halbleiterepitaxie verglichen. Diese Verfahren unterscheiden sich hinsichtlich des Einsatzes verschiedener Orientierungs‐, Trenn‐, Schleif‐, Läpp‐ und Poliermethoden. Die gestörte Oberflächenschicht, die infolge der mechanischen Bearbeitung entsteht, wird mit Reflexionselektronenbeugung und chemischer Ätzung charakterisiert. Die Abtragung der gestörten Oberflächenschicht durch Ionenätzung führt jedoch im Gegensatz zur chemischen Ätzung wiederum auf eine zwar dünnere, aber durch den Ionenbeschuß beeinträchtigte Oberflächenschicht.
The Calibration of the Advanced Stokes Polarimeter (1997)

We describe and apply the methods that have been developed to calibrate the Advanced Stokes Polarimeter and to compensate for the polarization effects introduced by the Vacuum Tower Telescope at the National Solar Observatory/Sunspot. A seven-parameter model of the telescope is fitted to data obtained at a variety of mirror angles using observations of both the center of the solar disk and that point within a sunspot umbra at which the magnetic field is oriented as close to the line of sight as possible. The response matrix of the polarimeter itself is determined by the use of polarizing calibration optics that modify the polarization state of the beam exiting the telescope but before entering the polarimeter. A global least-squares solution is obtained simultaneously for the response matrix and the telescope parameters. A detailed gain-correction procedure is described that reduces the multiplicative gain errors in the spectral images to typically less than 1%. We have successfully recovered net-linear polarization profiles with peak amplitudes of 1 × 10-3Ic against an instrumentally produced background polarization of 1-5 × 10-2Ic. Net-polarization signals smaller than 3 × 10-4Ic are lost, even with sufficient averaging, in a background due to photometric and other calibration errors.
Coherence studies of geomagnetic fluctuations in the frequency range .05 to 10 Hz (1982)

Fluctuations in the horizontal component of the earth's magnetic field were measrued at a land site (La Mesa) and on the floor of Monterey Bay at a depth of 70 meters. The measurements span a 19-hour period (August 17/18, 1982). Assuming a circular polarization basis set, analysis was conducted to determine the coherence between the two sites in the frequency range .05-10 Hz. Preliminary analysis indicates a high degree of coherence from .05-.4 Hz. Also, a study of the polarization of the micropulsation field at each site was conducted in terms of Stokes parameters.

Secretin‐like choleretic effect of prostaglandins E1 and E2 in cats. (1976)

1. The effects of intraportal and hepatic arterial infusion of prostaglandins E1 and E2 on liver function and circulation was studied in fasting chloralose anaesthetized cats. 2. Infusion of the prostaglandins at rates of 0‐1, 1‐0 and 5‐0 mug/kg.min caused a 35‐40% increase in bile flow. This may be explained by a decrease in the reabsorption or a secretion of sodium ions by the ductular cells. The canalicular bile production and bile flow. This may be explained by a decrease in the reabsorption or a secretion of sodium ions by the ductular cells. The canalicular bile production and bile acid excretion was not affected by the prostaglandins. 3. Infused at rates of 1‐0 and 5‐0 mug/kg.min the prostaglandins caused a transient decrease in mean arterial blood pressure and mesenteric vascular resistance. The resistance in the intrahepatic arterioles and low‐pressure vessels was not affected. 4. The prostaglandins did not influence the splanchnic uptake of oxygen and ethanol, whereas a slight increase in the splanchnic glucose output occurred. 5. The effects of the two prostaglandins were identical and not related to the route of administration.
Nucleus-Specific Differences in GABA<sub>A</sub>-Receptor-Mediated Inhibition Are Enhanced During Thalamic Development (2000)

Inhibitory postsynaptic currents (IPSCs) mediated by GABA(A) receptors are much slower in neurons of the thalamic reticular nucleus (RTN) versus those in the ventrobasal complex (VB) of young rats. Here we confirm and extend those findings regarding GABA(A) response heterogeneity especially in relation to development. Whole cell patch-clamp recordings were used to investigate GABA(A) spontaneous and electrically evoked IPSCs (sIPSCs/eIPSCs) in RTN and VB cells of different aged rats. Consistent with earlier findings, sIPSC duration at P8-12 was considerably longer in RTN (weighted decay time constant: tau(D,W) = 56.2 +/- 4.9 ms; mean +/- SE) than in VB (tau(D,W) = 15.8 +/- 1.0 ms) neurons. Decay kinetics in RTN neurons did not differ at P21-30 (45.5 +/- 4.7 ms) or P42-60 (51.6 +/- 10.6 ms). In contrast, VB sIPSCs were significantly faster at both P21-30 (tau(D,W) = 10.8 +/- 0.9 ms) and P42-60 (tau(D,W) = 9.2 +/- 0.4 ms) compared with P8-12 animals. IPSCs displayed differential outward rectification and temperature dependence, providing further support for nucleus-specific responses. tau(D,W) increased with membrane depolarization but with a net larger effect in VB. By contrast, tau(D,W) was always smaller at higher temperatures but with relatively greater difference observed in RTN. Thus nuclear differences in GABA(A) IPSCs are not only maintained, but enhanced in the mature rodent under physiological conditions. These findings support our hypothesis that unique GABA(A) receptors mediate slowly decaying RTN IPSCs that are a critical and enduring feature of the thalamic circuit. This promotes powerful intranuclear inhibition and likely prevents epileptiform thalamocortical hypersynchrony.
Automatic cloud and cloud shadow removal method for landsat TM images (2011)

Optical Remote Sensing Images are often interfered by clouds and their shadows. In this research, a scheme is proposed to automatically detect and remove clouds and their shadows by integrating complementary information from multitemporal images to generate the cloud-free composite images. Firstly, image classification is used to separate cloud regions and shadows regions of input images, and shadow regions can be revised by watershed detection method based on NDVI. Secondly, vegetation phenology characteristics of base image are applied to that of reference images where the complementary information is extracted from. Thirdly, fusion method based on multi-resolution pyramid is adopted for smoothing the mosaic artifacts. Finally, evaluation of pixels reliability is proposed to distinguish various sources of the composite image.
Identification of Blood Monocytes by Demonstration of Lysozyme and Peroxidase Activity (1971)

By a simple cytochemical method for the de- monstration of lysozyme (muramidase) activity, more than 95 % of human- and rat-blood monocytes could be identified and differentiated from lymphocytes. Peroxidase activity was seen in 83–88 % of the monocytes. When a staining method for lysozyme and peroxidase activity in the same cell was used, most blood mononuclear cells showed neither or both kinds of enzyme activity. Of the rat mononuclear cells, 6.9 % showed peroxidase activity alone
Probing Charge Separation in Structurally Different C<sub>60</sub>/exTTF Ensembles (2003)

The scope of the present work is to highlight the effects stemming from different C60/exTTF linkages (exTTF = 9,10-bis(1,3-dithiol-2-ylidene)-9,10-dihydroanthracene)-either via an anthracene unit or a dithiole ring. Particular emphasis is placed on photoinduced electron-transfer features. Therefore, we devised a new series of C60-exTTF ensembles, synthesized via 1,3-dipolar cycloaddition and Diels-Alder cycloaddition reactions, in which exTTF units are separated from C60 by two single bonds (3a-c, 4), one vinylene unit (5a), or two vinylene units (5b). The cyclic voltammetry reveals an amphoteric redox behavior with remarkably strong electron-donor ability of the trimethyl-substituted exTTF moiety in 4 and 5a,b. Steady-state and time-resolved photolytic techniques show that the fullerene singlet excited state in (3a-c, 4, and 5a,b) is subject to a rapid electron-transfer quenching. The resulting charge-separated states, that is C60*(-)-exTTF*+, were identified by transient absorption spectroscopy. We determined radical pair lifetimes of the order of 200 ns in benzonitrile. This suggests (i) that the positive charge of the exTTF*+ is delocalized over the entire donor rather than localized on one of the 1,3-dithiole rings and (ii) that linking exTTF via the anthracene or 1,3-dithiole ring has no appreciable influence. Increasing the donor-acceptor separation via implementing one or two vinylene units as spacers led to improved radical pair lifetimes (5a: tau = 725 ns; 5b: tau = 1465 ns).
Optical switching: switch fabrics, techniques, and architectures (2003)

The switching speeds of electronics cannot keep up with the transmission capacity offered by optics. All-optical switch fabrics play a central role in the effort to migrate the switching functions to the optical layer. Optical packet switching provides an almost arbitrary fine granularity but faces significant challenges in the processing and buffering of bits at high speeds. Generalized multiprotocol label switching seeks to eliminate the asynchronous transfer mode and synchronous optical network layers, thus implementing Internet protocol over wavelength-division multiplexing. Optical burst switching attempts to minimize the need for processing and buffering by aggregating flows of data packets into bursts. In this paper, we present an extensive overview of the current technologies and techniques concerning optical switching.
Distribution, activity and range use of male caribou in early summer in Northern Yukon, Canada (1986)

Males of the Porcupine Caribou Herd separated from females from the onset of spring migration until they joined them on the calving grounds in late June or early July, 4-6 weeks later. From late May to late June males spent an average of 50% of their time feeding and less than 2% standing and trotting/running. Males spent an average of 29% of their time lying and 19% walking, except in mid-June (40% lying, 6% walking). The average lengths of active and resting periods were 112 minutes and 104 minutes, respectively, from late May to mid-June, but decreased sharply in late June to 78 minutes and 69 minutes, respectively. Tussock meadows were selected in late May and early June, wet sedge meadows were avoided until late June, dwarf shrub heaths were avoided after late May, and alluvial willow thickets were avoided in late May and early June but were selected in mid-June and late June. Caribou fed primarily on lichens and Vaccinium in late May, lichens and Eriophorum in early June, Eriophorum in mid-June and Salix in late June.

Implementation of a Hardware-Optimized MPI Library for the SCMP Multiprocessor (2004)

As time progresses, computer architects continue to create faster and more complex microprocessors using techniques such as out-of-order execution, branch prediction, dynamic scheduling, and predication. While these techniques enable greater performance, they also increase the complexity and silicon area of the design. This creates larger development and testing times. The shrinking feature sizes associated with newer technology increase wire resistance and signal propagation delays, further complicating large designs. One potential solution is the Single-Chip Message-Passing (SCMP) Parallel Computer, developed at Virginia Tech. SCMP makes use of an architecture where a number of simple processors are tiled across a single chip and connected by a fast interconnection network. The system is designed to take advantage of thread-level parallelism and to keep wire traces short in preparation for even smaller integrated circuit feature sizes.\nThis thesis presents the implementation of the MPI (Message-Passing Interface) communications library on top of SCMP's hardware communication support. Emphasis is placed on the specific needs of this system with regards to MPI. For example, MPI is designed to operate between heterogeneous systems; however, in the SCMP environment such support is unnecessary and wastes resources. The SCMP network is also designed such that messages can be sent with very low latency, but with cooperative multitasking it is difficult to assure a timely response to messages. Finally, the low-level network primitives have no support for send operations that occur before the receiver is prepared and that functionality is necessary for MPI support.
