Glycoprotein Ib (GPIb)-dependent and GPIb-independent pathways of thrombin-induced platelet activation (1991)

In this study, the question of whether glycoprotein Ib (GPIb) mediates both high and moderate affinity pathways of alpha-thrombin-induced platelet activation was examined. Flow cytometric studies, using a panel of monoclonal antibodies (MoAbs), showed that Serratia marcescens protease treatment removed greater than 97% of the glycocalicin portion of GPIb but did not affect the changes in the expression of GPIX or GMP- 140 that were induced by high concentrations of alpha-thrombin (10 nmol/L). However, Serratia treatment almost completely abolished the increase in platelet surface GMP-140 induced by low concentrations of alpha-thrombin (0.5 nmol/L) and diminished the downregulation of platelet surface GPIX by 60.9% +/- 5.6% (mean +/- SEM, n = 3). When present in 20-fold molar excess, an MoAb directed against the alpha- thrombin/von Willebrand factor (vWf) binding domains of GPIb completely blocked the ristocetin-dependent binding of vWf to platelets but inhibited only to about 50% the binding of alpha-thrombin and the activation-dependent binding of vWf. In platelets treated with Serratia marcescens protease to remove GPIb, a concentration of this MoAb 16,000- fold in excess of the maximum possible remaining copies of GPIb failed to inhibit platelet activation by alpha-thrombin. These studies demonstrate that activation of intact platelets by alpha-thrombin proceeds by both GPIb-dependent and GPIb-independent mechanisms.
Treatment of cutaneous larva migrans and <i>Toxocara</i> infection (2003)

The treatment of cutaneous larva migrans and Toxocara infection relies on antihelminthic agents such as thiabendazole, albendazole and ivermectin. The efficacy of these agents varies according to the helminthic disease.
High‐capacity resource sharing schemes for broadband wireless networks (2004)

Abstract The unique capabilities of new cellular systems are expected to provide users with integrated multimedia services. Since the air interface still represents the system bottleneck, this paper proposes novel scheduling techniques to integrate efficiently the support of real‐time traffic (i.e. voice and video) and data bursty traffic under quality of service (QoS) guarantees. Prioritization among traffic classes is adopted and a polling service discipline is employed within a class, where the permission rights of each traffic source are determined on the basis of token bucket regulators. Two polling‐based approaches are compared to serve the sources of a class: (i) when a source is enabled to transmit, a burst of packets is sent at once; (ii) within the time interval destined to a traffic class, a cyclic service of the sources is allowed on a packet basis. With realistic assumptions on both radio channel conditions and protocol signaling overhead, this paper compares these two different approaches and the dynamic slot assignment++ (DSA++) scheme appeared in the literature. The obtained results highlight that our second scheme (case ii) allows increasing the number of supported video traffic sources of many units with respect to DSA++. Finally, an analytical approach has been proposed for our second polling scheme. Copyright © 2004 John Wiley & Sons, Ltd.
Benzo [b]-promazines, chlorpromazine free radical and analino-N, N-dimethylpropylamine analogs influence rat striatal DA-adenylate cyclase and calmodulin-phosphodiesterase. (1982)

A series of Benzo [b]-promazines and analino-N, N-dimethylpropylamine analogs and the free radical of chlorpromazine were compared to chlorpromazine and promazine in the rat striatum for their ability to inhibit either dopamine activated adenylate cyclase or calmodulin stimulation of a partially purified high Km cyclic AMP phosphodiesterase. Chlorpromazine and the corresponding free radical were generally the most potent inhibitors of the two enzyme preparations, however, Piperazino-Benzo [b]-promazine, 1-Oxo-Benzo [b]-promazine, N-38-76-3A and Benzo [b]-promazine were relatively effective inhibitors. To a lesser extent, tyrosine, N-57-77, Piperidino-Benzo [b]-promazine, Diethyl-Benzo [b]-promazine, promazine and 1-Oxo-Diethyl-Benzo [b]-promazine exerted varying degrees of antagonism of the two enzymes. In all instances the compounds inhibited dopamine-sensitive adenylate cyclase to a greater extent than the calmodulin activated phosphodiesterase.
Race crossing in man (Eugenics Lab. Mem. XXXVI) (1954)

Injuries to peripheral branches (IAN, LN, LBN) of the trigeminal nerve during the removal of M3s are known and accepted risks in oral and maxillofacial surgery practice. These risks might be reduced by modifications of evaluation or surgical techniques, depending on the surgeon's judgment in individual patients. If a nerve injury does occur, prompt recognition, subjective and objective evaluation,and development of a treatment plan, if the sensory deficit fails to resolve in a reasonable period and is unacceptable to the patient, give the patient the best chance of achieving improvement or recovery of sensory function in the distribution of the injured nerve. Microneurosurgery may produce return of useful sensory function or complete sensory recovery, if done in a timely fashion by an experienced microsurgeon, in greater than 80% of patients who sustain nerve injuries during the removal of M3s.
Effect of insulin administration during follicular growth on serum glucose and hormone profiles in ewe lambs (1992)

Twenty ewe lambs received either 0 or 1 IU of Lente insulin kg −1 body weight from day 12 of the estrous cycle until 24 h after estrus. Blood samples were collected at 15-min intervals for 6 h after treatment on days 12, 14 and 16 of the estrous cycle. Following insulin injection, serum insulin was elevated (P < 0.05) and was accompanied by a decrease in serum glucose levels. Insulin treatment did not affect (P > 0.10) luteinizing hormone secretory characteristics, ovulation rate, or subsequent litter size. Key words: Insulin, glucose, sheep, luteinizing hormone

Scribe: self-organized contention and routing in intelligent broadcast environments (2004)

Large-scale sensor networks (LSSNs) are systems with a very large number of networkable sensors deployed randomly over an extended environment, rendering it observable. These randomly deployed networks need no pre-design and configure themselves through a process of self- organization. The purpose of our research is to consider how reliable, robust and scalable location-addressed communication can be assured in LSSN systems built from large numbers of inexpensive and unreliable nodes with limited capabilities using only broadcast communication. We present viable broadcast-based protocols for channel access and network organization. We focus on the situation where the transmission radius of individual nodes is much smaller than the size of the system, so that most messages need a large number of "hops" to reach their destination. In view of this, and given the unreliable nature of the nodes, we consider whether an inherently redundant intelligent broadcast scheme can provide sufficient message reliability. This bottom-up approach to communication is shown to provide reliable communication at the system level and to outperform more complex model-based approaches.

Low-Temperature Scaling of the Critical Current in 1 G HTS Wires (2015)

We present highly detailed temperature, magnetic field and field angle dependent measurements of the critical current of a state-of-the-art commercial first-generation Bi-2223 high temperature superconductor wire (Sumitomo new type H high current density DI-BSCCO). By scaling the applied field values at different angles using the Blatter electron mass anisotropy expression, we demonstrate that the measurements at each temperature from 20 to 85 K collapse onto a common curve with respect to the scaled magnetic field. However, the scaling parameter is found to range from 7 at 80 K to 13 at 25 K, far below the values reported in the literature for the electron mass anisotropy of this material, and far closer to the values reported for similar analyses of data obtained from the much less anisotropic superconductor YBCO. This suggests that a mechanism of similar magnitude underlies and determines the results obtained for both materials in spite of their greatly differing electronic mass anisotropies. By normalizing the results to the self-field critical current and the irreversibility field, we are able to obtain a single universal curve describing the performance of the superconductor across the full range of operating conditions. In contrast to pinning-engineered YBCO coated conductors, we find that the low-temperature behavior of BSCCO wires can be well correlated with its high-temperature behavior. Knowledge of this straightforward behavior of this commercial superconductor across the full parameter space of temperature, field and field angle will be invaluable to engineers working with this material to construct machines or devices.
Gas permeabilities and permselectivity of photochemically crosslinked polyimides (1995)

Abstract Photosensitive polyimide BTDA‐3MPDA was modified by UV irradiation. The structure of UV‐irradiated polyimides was investigated by FTIR and gel fraction measurements. The results showed that longer UV exposure time resulted in a higher extent of crosslinking. The gas permeabilities of hydrogen, oxygen and nitrogen through UV‐irradiated polyimides were characterized in a temperature range from 30°C to 90°C. Photocrosslinking resulted in a sharp decline in gas permeability for hydrogen, oxygen, and nitrogen through polyimide in the initial stage of photocrosslinking. Then, as the crosslinked benzophenone percentage amounted to 28–38% for hydrogen, 17–31% for oxygen and 3–28% for nitrogen, the gas permeabilities showed another sharp decline. Gas permselectivity increased significantly with the progress of photocrosslinking, and it can be adjusted in a wide range by controlling the extent of crosslinking. Arrhenius plots of gas permeability for hydrogen and oxygen through UV‐irradiated polyimides are straight lines; for nitrogen, however, change in the slope of the straight line is observed and activation energies for hydrogen and oxygen permeation show abrupt increases when crosslinked benzophenone percentage amounts to about 30%. UV‐irradiated polyimides with simultaneous high gas permeability and permselectivity make them ideal candidate materials for gas separation. © 1995 John Wiley & Sons, Inc.
Malignancy rate associated with Bethesda category<scp>III</scp>(<scp>AUS/FLUS</scp>) with and without repeat fine needle aspiration biopsy (2016)

The findings showed that repeat FNAB for initial AUS/FLUS category was associated with a significantly increased malignancy rate compared with those without repeat FNAB. Repeat FNAB could help selection of patients with AUS/FLUS to triage to surgery. Therefore, repeat FNAB for nodules with AUS/FLUS on initial FNAB was suggested.
Post-school Education and Work: The Depression Years in Western Australia (1982)

From an examination of developments in post-school education in Western Australia during the Great Depression, explanations are sought for disillusionments at the time with the State's education system and also for subsequent policies to impose accountability and economy upon educational institutions and foster a utilitarian emphasis in the curriculum. Royal Commissions by Justice A. Wolff — on Youth Employment and the Apprenticeship System and on the Administration of the University of Western Australia — are vital to an understanding of community attitudes and later developments in post-school education policy. Community attitudes in the thirties bear a remarkable resemblance to attitudes during the recession of the seventies.
Risk factors for breast cancer in nulliparous women (1999)

The relation between hormonal and lifestyle factors and breast cancer risk in nulliparae was investigated using data from two case-control studies conducted in Italy between 1983 and 1994. The study included 1041 nulliparae with histologically confirmed incident breast cancer and 1002 nulliparous controls admitted to hospital for a wide range of acute, non-neoplastic, nonhormone-related diseases. In premenopausal nulliparae, there was an inverse relation with age at menarche [odds ratios (OR) 0.45; 95% confidence intervals (CI) 0.24-0.86 for > or = 15 years vs < 12], while no association emerged in postmenopausal. Breast cancer risk increased with age at menopause, the OR being 1.91 (95% CI 1.26-2.90) for nulliparae reporting age at menopause > or = 53 years compared with < 45. Abortion was not related to breast cancer risk, the OR being 0.92 for any spontaneous, 0.97 for any induced and 0.77 for > or = 2 total abortions compared to none. The OR was 1.75 (95% CI 1.03-2.97) for women reporting their first abortion at age > or = 30 years compared with < 30. Oral contraceptives and hormone replacement therapy in menopause were moderately related to risk. The OR was 2.71 (95% CI 1.85-3.95) in nulliparae with a family history of breast cancer and 1.60 (95% CI 1.20-2.14) in those with a history of benign breast disease. Compared with nulliparae reporting a low physical activity, the OR was 0.79 (95% CI 0.54-1.16) for those reporting intermediate/high activity. Breast cancer risk increased with total energy intake, the OR being 1.65 (95% CI 0.99-2.75) in the highest tertile; beta-carotene was inversely related to risk (OR 0.60, 95% CI 0.38-0.95) for the highest tertile. Thus, most risk factors for breast cancer in nulliparae were similar to those in women generally.
Governments as Leaders of Employment Relations: Equity, Efficiency and Politicisation as Driving Forces of Reform? (2003)

Governments and public sectors are not always regarded as exemplary managers.Yet in employment relations (ER) they have frequently led the way to reform, not least of all in the state of New South Wales (NSW), Australia.The twelve years of a Labor government from 1976 marked a period of unprecedented ER reform, substantially based on equity.The subsequent government supported some of these ER policies but initiated an ambitious reform agenda in ways that undermined the earlier ER gains.In particular, the introduction of the NSW Senior Executive Service (SES) with its focus on organisational efficiency can be viewed as an enabling and inhibiting force in ER reform.The present Labor government in continuing the SES has moved to ER driven by political choice.This article uses literature and document review and University of Technology (UTS) research undertaken on behalf of the Audit Office of NSW (1998) to examine the impact of different NSW governments' approaches to ER
Who is the best connected scientist? A study of scientific coauthorship networks (2000)

Using data from computer databases of scientific papers in physics, biomedical research, and computer science, we have constructed networks of collaboration between scientists in each of these disciplines. In these networks two scientists are considered connected if they have coauthored one or more papers together. We have studied many statistical properties of our networks, including numbers of papers written by authors, numbers of authors per paper, numbers of collaborators that scientists have, typical distance through the network from one scientist to another, and a variety of measures of connectedness within a network, such as closeness and betweenness. We further argue that simple networks such as these cannot capture the variation in the strength of collaborative ties and propose a measure of this strength based on the number of papers coauthored by pairs of scientists, and the number of other scientists with whom they coauthored those papers. Using a selection of our results, we suggest a variety of possible ways to answer the question "Who is the best connected scientist?"

A Bistable Pneumatic Microswitch For Driving Fluidic Components (1995)

This paper presents fabrication and performance of a pneumatic 3/2-way switch for the actuation of passive fluidic components. The switch has two stable states which can be hold without additional power consump- tion. Two silicon microvalves, driven by thermally induced buckling of silicon microbridges, are acting as inlet and outlet of'the operation volume. Powered with short electrical pulses the switch can be toggeled bet- ween the two stable states. With pulses of 10-12( ms duration at 4-4.5 W input power pressures of up to z bar can be controlled. Both large deflections (e.g. I cm piston movement) as well as high forces can be achieved.

Nanotech Commercialization in the United States [Commercialization (2010)

In the previous issue, I focused on R&D trends and also referred to concerns regarding the United States and the importance of maintaining steady funding by the public and private sectors for emerging technologies such as nanotech. The overall R&D funding climate is always a leading indicator of future innovation activity, and delays or reductions can spread out the time necessary to bring to market commercial products. Though companies and even the government become hard pressed to keep up the pace in a down economy, the ramifications of falling behind can be severe in terms of lost opportunities and competitiveness. Many areas of nanotechnology are still in a nascent stage of development, and sudden breakthroughs may lead to strong disruptions in existing technology and product markets in relatively short order.
Acinar cell proliferation in the parotid and submandibular salivary glands of the neonatal rat (1982)

Although the rat salivary glands are deficient in acini at birth, acinar cells proliferate rapidly during the early post-natal period. The pattern of acinar cell proliferation was analysed in the parotid and submandibular glands of neonatal rats from day to birth until day 34. Mitotic and [3H]thymidine ([3H]TdR) labelling indices of the two glands show distinctly different patterns. Analysis of cell division in the rat parotid gland demonstrated a peak of mitotic index at 14 days (2.9 +/- 0.4%) and labelling index at 16 days (25.2 +/- 2.1%). Submandibular gland acinar cell proliferation reaches a zenith between 7-8 days; labelling index (14.2 +/- 1.1%) and mitotic index (2.3 +/- 0.3%). Cell proliferation decreases rapidly in both glands after reaching a peak in activity. Gland size increases more rapidly in both glands after gland which correlates with the earlier shift from cell proliferation to differentiation which occurs in this organ. Circadian rhythms of [3H]TdR incorporation were also investigated in this study. A circadian rhythm of [3H]TdR incorporation into DNA occurs at 15 days after birth with a peak at 06.00 hours in both glands and a trough occurring at 15.00 hours in parotid gland and 18.00 hours in the submandibular gland. Determination of specific activity of DNA (ct/min per microgram DNA) on days 8, 10, 12, 13, 14, 15, and 16 after birth at 06.00 and 15.00 hours indicated that a circadian rhythm in [3H]TdR incorporation into DNA began on day 14. The developmental switch from suckling to solid food may be an initiating factor in the sychronization of the circadian rhythm in cell proliferation.
A novel initial rotor-position estimation method for BLDC motors based on four voltage pulses (2010)

This paper presents a new initial rotor position estimation method for brushless dc motors (BLDC). It consists in injection of four short voltage pulses at the motor terminals and then based on the evaluation of the voltage measured at the terminal of the non-energized (floating) stator phase, the position is estimated. The first three pulses are applied for a very short time to evaluate the rotor position while the fourth (last) pulse is used only for detection of magnet polarity. The estimation time of the position with an uncertainty of 180° is independent of the motor electrical time constant, being less than 140 μs, while the detection of magnet polarity could last longer (up to few milliseconds) until the iron core is saturated. The proposed method is proved only for salient pole BLDC motors (L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sub> ≠L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">q</sub> ). The advantages of the proposed method are taught to be: quickness, simplicity, accuracy, low computation effort, and the most important: insensitive to the high voltage disturbances specific to the battery voltage in the vehicles. No current sensor is used for the proposed setup. Experimental results are provided to prove the concept and validate the solution.
A 1-V operated polymer vertical transistor with high on/off current ratio (2009)

A 1-V solution-processed polymer vertical transistor with on/off current ratio higher than 2 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup> is firstly demonstrated. The channel length is 200 nm. A new structure is used to perform reliable leakage control. Significant impacts of thin film morphology and metal doping effect on the leakage current of organic vertical transistors are firstly observed and recognized as two new leakage phenomena. The complete leakage control and the reliable process in this report enable polymer vertical transistors for real applications.
