Breast-conserving surgery with or without radiotherapy in women with ductal carcinoma in situ: a meta-analysis of randomized trials (2007)

The conclusion from our meta-analysis is that the addition of radiation therapy to lumpectomy results in an approximately 60% reduction in breast cancer recurrence, no benefit for survival or distant metastases compared to excision alone. Patients with high-grade DCIS lesions and positive margins benefited most from the addition of radiation therapy. It is not yet clear which patients can be successfully treated with lumpectomy alone; until further prospective studies answer this question, radiation should be recommended after lumpectomy for all patients without contraindications.

A programmable VLSI architecture for computing multiplication and polynomial evaluation modulo a positive integer (1988)

A programmable VLSI architecture with regular, modular, expansible features is designed for computing AB mod N, AB+C mode N, and polynomial evaluation modulo N. The size of the resultant circuit can be easily expanded to improve the security of cryptosystems without making any change to its control circuit. The computing procedures for all N throughout the range of 0<N<2/sup n-1/ are identical. Therefore, the circuit is well-suited for those systems in which the value of N is alternated frequently.<<ETX>>
The Effect of Injector and Intake Port Design on In-Cylinder Fuel Droplet Distribution, Airflow and Lean Burn Performance for a Honda VTEC-E Engine (1996)

<div class="htmlview paragraph">The droplet velocity, size and distributions of iso-octane fuel from single hole and twin jet air-assist injectors have been measured by phase Doppler velocimetry in the pent-roof for two cylinder head designs of firing four-valve engines running at 1500 rpm, together with the airflow during induction and compression. The use of the twin jet air-assist injector together with the introduction of a transfer-passage between the two intake ports of a Honda VTEC-E valve train arrangement resulted in reduction in ISNOx and COV-1mep of the order of half of those with the single hole injector design without a transfer passage. Droplets, for both heads and injectors, having passed the inlet valves, impinged directly onto the sleeve opposite to their entry without striking the exhaust valves and had velocities up to 30 m/s and Sauter mean diameters which varied from 20 to 50pm. During the intake stroke, some air passed through the transfer-passage from the secondary intake valve VTEC-E port to the primary valve port and probably convected some evaporated fuel vapor thereby redistributing the proportion of fuel vapor entering the combustion chamber from each port relative to the design without the transfer passage. The use of the twin jet air-assist injector resulted in the impingement of droplets on the sleeve 15° CA earlier than for the single hole injector and to displacement of the location of maximum droplet flux by about 21/2 cm along the cylinder periphery, away from one exhaust valve and towards the primary inlet valve. In this region and over the duration of vapor release, approximately between 450° and 500° CA, the vapor cloud was convected by the air motion towards the cylinder head, in contrast to the use of the single hole injector which was generated at a location which resulted in convection of the corresponding cloud towards the piston crown. The pathlines during induction and compression of the rich vapor clouds are therefore different, providing evidence of a different mechanism for mixture stratification for the engine with the twin jet air-assist injector accounting for the improvement in ISNOx and COV-imep observed in the dynamometer tests.</div>
Polyimides by Diels‐Alder polyaddition of α‐pyrones (1994)

Abstract New linear polyimides 11 were synthesized via Diels‐Alder addition polymerization of α‐pyrones 9 with bismaleimides 10 . The number‐average molecular weights M n range from 10 000 to 34 000 g. mol (gel‐permeation chromatography). The chemical structure of these polymers is supported by X‐ray crystallography, NMR spectra and model reactions. The Diels‐Alder addition occurred with high endo selectivity.

<i>N</i>-terminal sequence analysis of polypeptide at the picomole level (1981)

This paper describes a manual method for N-terminal sequence analysis of polypeptides at subnanomole sensitivity. The polypeptide is degraded stepwise by using the dimethylaminoazobenzene isothiocyanate/phenyl isothiocyanate double-coupling method, and the released dimethylaminoazobenzenethiohydantoins of amino acids were identified by reversed-phase high-pressure liquid chromatography. The dimethylaminoazobenzenethiohydantoins are coloured compounds and can be detected in the visible region with the sensitivity limit of 1 pmol (signal-to-baseline noise ratio 5). A high-pressure liquid-chromatographic method was developed for complete analysis of all amino acid dimethylaminoazobenzenethiohydantoin derivatives, including the by-products of serine and threonine. Thus, without use of an automatic sequenator or radioactive materials, it is possible to determine the complete sequence of peptides and N-terminal sequence of proteins with less than 1 nmol of material.
Usefulness of collagen plugging with VasoSeal® after PTCA as compared to manual compression with identical sheath dwell times (1998)

This study investigated the usefulness of collagen plugging with VasoSeal® in patients after PTCA compared to a control group having identical sheath dwell times and therefore comparable levels of anticoagulation. A total of 150 patients were enrolled in this prospective and randomized study. Sheaths were pulled at exactly 5 h after arterial puncture. Time to hemostasis and local complications were determined. There were no statistical differences in baseline characteristics. The mean time to hemostasis in the collagen group was significantly shorter (3 ± 3 min) than that of the control group (17.4 ± 7 min). At 24 h, 23% of the collagen group patients had a small, 1% a medium and 4% a large hematoma. In the control group, 32% had a small, 4% a medium sized, but no patient a large hematoma. After collagen, one patient developed a pseudoaneurysm needing vascular surgery. In the control group, no major complication occurred. Compared to patients with manual compression at an identical sheath dwell time and an identical level of anticoagulation, there was a significant reduction in time to hemostasis but no statistical difference regarding local complications. Although the incidence of medium or large hematoma was low, the trend towards a decreased risk of smaller hematomas seemed to be counterbalanced by an increased risk of larger hematomas. Cathet.

A camera-based system for early detection of drowning incidents (2003)

We present in this paper a camera-based system for detecting drowning incidents in a swimming pool at the earliest possible stage. The system consists of two main parts: a vision component which can reliably detect and track swimmers in spite of large scene variations of monitored pool areas, and an event-inference module which parses observation sequences of swimmer features for possible drowning behavioral signs. The vision component employs a model-based approach to represent and differentiate background pool areas and foreground swimmers. The event-inference module is constructed based on a finite state machine, which integrates several reasoning rules formulated from universal motion characteristics of drowning swimmers. Possible drowning incidents are quickly detected using a sequential change detection algorithm. The proposed system has been applied to a number of video clips of simulated drowning, and promising results have been obtained.
Low Power Consumption Red Light-Emitting Diodes Based on Inorganic Perovskite Quantum Dots under an Alternating Current Driving Mode (2018)

Inorganic perovskites have emerged as a promising candidate for light-emitting devices due to their high stability and tunable band gap. However, the power consumption and brightness have always been an issue for perovskite light-emitting diodes (PeLEDs). Here, we improved the luminescence intensity and decreased the current density of the PeLEDs based on CsPbI₃ quantum dots (QDs) and p-type Si substrate through an alternating current (AC) driving mode. For the different driving voltage modes (under a sine pulsed bias or square pulsed bias), a frequency-dependent electroluminescent (EL) behavior was observed. The devices under a square pulsed bias present a stronger EL intensity under the same voltage due to less thermal degradation at the interface. The red PeLEDs under a square pulsed bias driving demonstrate that the EL intensity drop-off phenomenon was further improved, and the integrated EL intensity shows the almost linear increase with the increasing driving voltage above 8.5 V. Additionally, compared to the direct current (DC) driving mode, the red PeLEDs under the AC condition exhibit higher operating stability, which is mainly due to the reducing accumulated charges in the devices. Our work provides an effective approach for obtaining strong brightness, low power consumption, and high stability light-emitting devices, which will exert a profound influence on coupling LEDs with household power supplies directly.
Tumor Necrosis Factor Receptor-2 Signaling Attenuates Vein Graft Neointima Formation by Promoting Endothelial Recovery (2007)

A Precise GPS Sensor Subsystem for Vehicle Platoon Control (2003)

Coordination of vehicles in high-density traffic increases the efficiency of transportation infrastructure usage while improving safety standards. The concept of Collaborative Driving Systems (CDS) addresses this issue by linking several vehicles in a platoon through local communication links and in-vehicle positioning and control systems. A CDS will enable vehicles to communicate and follow a leader vehicle thus forming a platoon of vehicles. As a part of a Canadian initiative to develop technologies for CDS, this paper investigates the performance of carrier phase GPS as a positioning subsystem for a CDS. This includes relative positioning of vehicles with centimeter level accuracy and estimating their relative speeds to an accuracy of a few centimeters per second. This research investigates carrier phase technology applied to a host vehicle positioning itself in a platoon of vehicles using the GPS subsystem. The advantages of the GPS subsystem with inter-vehicle communication in a CDS are illustrated over alternative technologies especially in issues such as maintaining the asymptotic stability in vehicle platoons. Tests were conducted using four instrumented vehicles, each equipped with a precise GPS position and heading determination system using a two-antenna configuration. This enabled the relative position estimation between vehicles as well as between antennas with a known interantenna baseline. Several driving scenarios are presented including joining, leaving, and passing a platoon of vehicles. The achievable accuracy in relative position and velocity is investigated.
Improvement of a Human-Machine Interface (HMI) for Driver Assistance Using an Event-Driven Prompting Display (2010)

Visual display systems showing lateral roadway position of a vehicle have been used in advanced vehicle control and safety systems for driver assistance in hazardous conditions, e.g., in snowplowing operations. A simple simulation of lateral control stability of the vehicle indicates the adverse effect of dead-time resulting from the driver glancing back and forth between windshield and display. An event-driven prompting display is presented to reduce the effect of the dead-time and improve the safety of the driver assistance system. Test results in actual driving provide a comparison of the performance of the new display versus the original display system, and clearly indicate the improvement in lateral stability in driving a vehicle.
Protective Effects of Amphotericin B Against Spontaneous and Transplantable Murine Tumors 2 (1976)

Two tumor systems were used to test prophylactic effects of amphotericin B (AmB). When 0.5 mg AmB was given ip every 2 weeks to AKR mice beginning at 8 weeks of age, the 50% tumor incidence for spontaneous lymphoma development was delayed 2-3 months. In the second tumor system, BALB/c mice received injections of either 20 or 50 mug AmB before receiving MOPC-315-C cells sc. The mice given the low dose of AmB demonstrated a decreased tumor incidence and a reduced tumor growth rate, when compared with controls. Opposite effects were found for the group administered the high dose; tumor incidence and rate of growth were increased.

Bicarbonate abolishes intracellular alkalinization in mitogen‐stimulated 3T3 cells (1989)

An increase in intracellular pH (pHi) following mitogenic stimulation has been reported in a variety of mammalian cells (W. Moolenaar, Annu. Rev. Physiol., 48:363-376, 1986; E. Rozengurt, Science, 234:161-166, 1986). This increase is currently believed to constitute a "permissive" signal in the process of cell activation (A.E. Lagarde and J.M. Pouyssegur, Cancer Biochem. Biophys. 9:1-14, 1986). Since the majority of studies of this phenomenon have been conducted in the nonphysiological milieu of bicarbonate-free solutions, we have undertaken a study of the effects of bicarbonate and CO2 on mitogen-induced intracellular alkalinization in NIH 3T3 cells. Using nuclear magnetic resonance (NMR) spectroscopy and novel 31P NMR pH indicators (2-amino-phosphono-carboxylic acids) we found that mitogen induces an increase in pHi of 0.16 units only in cells bathed in medium containing low concentrations of bicarbonate (less than 1 mM) and not in cells bathed in medium containing physiological levels of bicarbonate (10-30 mM). In addition to abolishing the mitogen-induced alkalinization, bicarbonate stabilizes pHi at 7.25 units as the external pH (pHe) is varied from 7.0 to 7.6. In contrast, in a bicarbonate-free medium pHi increases from 6.9 to 7.3 over the same range of external pHs. At a constant external pH, increasing the bicarbonate/CO2 concentration results in an increase in pHi from 6.9 in bicarbonate-free solution to 7.25 in a bicarbonate-buffered medium. This relationship is hyperbolic with half-maximal effect occurring at a concentration of 0.4 mM bicarbonate at pH 7.05 and 37 degrees C. Our results suggest that the observations of mitogen-induced alkalinization may be due to the use of nonphysiological bicarbonate-free media. Since this increase in pHi is not observed in physiological media where bicarbonate concentrations are usually greater than 20 mM, we conclude that an increase in pHi is not an obligatory or usual part of the cellular response to growth factors in vivo.
H Carey, Believing in Australia: A Cultural History of Religions (1997)

Carey states that the basic intention of this 'nonspecialist' study '...has been to examine religious cultures as they have reflected cultural transformations in Australian society (p. x)'. She thereby implies that religion has been a secondary or dependent variable in Australian history, and also a rather puny one. Religious culture in Australia, she asserts, 'has been characterised by transience and transformation', and was 'achieved by the action of the waves of contact and migrant experiences, from first European occupation to postcolonial society, on the beach of the Australian experience.' Aboriginal religions, by contrast, are religions of the land and, it seems, religions in a proper and strong sense.
Laboratory Measurements of Axis Ratios for Large Raindrops (1999)

The oscillations of moderate to large raindrops are investigated using a seven-story fall column with shape data obtained from multiple-strobe photographs. Measurements are made at a fall distance of 25 m for drops of D = 2.5-, 2.9-, 3.6-, and 4.0-mm diameter, with additional measurements at intermediate distances to assess the role of aerodynamic feedback as the source of drop oscillations. Oscillations, initiated by the drop generator, are found to decay during the first few meters of fall and then increase to where the drops attained terminal speed near 10 m. Throughout the lower half of the fall column, the oscillation amplitudes are essentially constant. These apparently steady-state oscillations are attributed to resonance with vortex shedding. For D = 2.5 and 3.6 mm, the mean axis ratio is near the theoretical equilibrium value, a result consistent with axisymmetric (oblate/prolate mode) oscillations at the fundamental frequency. For D = 2.9 and 4.0 mm, however, the mean axis ratio is larger than the theoretical equilibrium value by 0.01 to 0.03, a characteristic of transverse mode oscillations. Comparison with previous axis ratio and vortex-shedding measurements suggests that the oscillation modes of raindrops are sensitive to initial conditions, but because of the prevalence of off-center drop collisions, the predominant steady-state response in rain is expected to be transverse mode oscillations. A simple formula is obtained from laboratory and field measurements to account for the generally higher average axis ratio of raindrops having transverse mode oscillations. In the application to light to heavy rainfall, the ensemble mean axis ratios for raindrop sizes of D = 1.5–4.0 mm are shifted above equilibrium values by 0.01–0.04, as a result of steady-state transverse mode oscillations maintained intrinsically by vortex shedding. Compared to the previous axis ratio formula based on wind tunnel measurements, the increased axis ratios for oscillating raindrops amount to a reduction of 0.1–0.4 dB in radar differential reflectivity ZDR, and an increase of about 0.5 mm for a reflectivity-weighted mean drop size of less than about 3 mm.
Controlled Coupling of Counterpropagating Whispering-Gallery Modes by a Single Rayleigh Scatterer: A Classical Problem in a Quantum Optical Light (2007)

We present experiments where a single subwavelength scatterer is used to examine and control the backscattering induced coupling between counterpropagating high-Q modes of a microsphere resonator. Our measurements reveal the standing wave character of the resulting symmetric and antisymmetric eigenmodes, their unbalanced intensity distributions, and the coherent nature of their coupling. We discuss our findings and the underlying classical physics in the framework common to quantum optics and provide a particularly intuitive explanation of the central processes.
Clinical use of diffusion-tensor imaging for diseases causing neuronal and axonal damage. (1999)

Diffusion-tensor imaging is an emerging technique that can supply microscopic structural information about tissue in vivo. With this technique it is possible to measure the amount of anisotropy of water diffusion within tissues and to assess the degree to which directionally ordered tissues have lost their normal integrity. This study was performed in four patients to evaluate the feasibility of applying this technique in clinical situations in which there is known or suspected damage to white matter tracts.
