Non-invasive measurement of coronary plaque from coronary CT angiography and its clinical implications (2013)

Coronary CT angiography (CTA) is increasingly used worldwide for direct, non-invasive evaluation of the coronary arteries. Advances in computed tomography (CT) technology over the last decade have enabled such reliable imaging of the coronary arteries. Beyond arterial stenosis, coronary CTA also permits assessment of atherosclerotic plaque (including plaque burden) and coronary artery remodeling, previously only achievable through invasive means. It has been shown that coronary plaque volumes for non-calcified and mixed plaques and the arterial remodeling index, correlate closely with invasive intravascular ultrasound. Several studies have also shown a strong relationship of adverse plaque features imaged by coronary CTA with acute coronary syndrome, all-cause death, major adverse cardiovascular events and myocardial ischemia. The aim of this review is to summarize current methods for quantitative measurement of atherosclerotic plaque features from coronary CTA and to discuss their clinical implications.
<title>Modeling the response of different WDM PON architectures to varying traffic load</title> (1999)

The introduction of wavelength division multiplexing into the access network is a potentially attractive alternative upgrade strategy to increasing the bit rate of passive optical networks (PON). A number of different methods have been proposed to implement a multi-wavelength PON and hence a careful assignment needs to be made of the most cost effective, both in the short term and for future increases in capacity. One key issue is the use of dynamic allocation of wavelengths, which allows the reconfiguration of the network in response to network demand. A model has been produced to simulate demand patterns on a PON, in order to quantify the benefits of dynamic assignment.

Fluid-Rock Characterization for NMR Well Logging and Special Core Analysis (2007)

terms of both its manufacturing and maintenance costs, and be applicable to as broad a range of markets as possible. APS has taken the approach of using a system using planetary gears to increase the speed of a conventional mud motor to 10,000 rpm. The mud flow is directed around the outside of the gear train, and a unique flow diversion system has been employed. A prototype of the motor was built and tested in APS's high-pressure flow loop. The motor operated per the model up to {approx}4200 rpm. At that point a bearing seized and the performance was severely degraded. The motor is being rebuilt and will be retested outside of this program.
The effect of extra framework species on the intrinsic negative thermal expansion property of zeolites with the LTA topology (2012)

X-Ray powder diffraction studies have been used to measure the thermal expansion properties of three zeolites with the LTA topology and provide details of the underlying structural changes. Siliceous ITQ-29 and dehydrated and hydrated silver zeolite A have large negative, moderate negative and positive thermal expansion coefficients, respectively.
Relationship between Muscle Oxygenation Kinetics and the Rate of Decline in Peak Torque during Isokinetic Knee Extension in Acute Hypoxia and Normoxia (2008)

To investigate whether low FiO2 affects muscle oxygenation and the rate of decline in peak torque (DR) during isokinetic knee extension, subjects performed 50 isokinetic knee extensions at 180 degrees /s and at 0.5 Hz while inhaling low O2 gas (12 %O2; H) or air (N). Muscle oxygenation kinetics was assessed by near-infrared spectroscopy, and whole-body V.O2 and HR were measured. We calculated total-, oxy- and deoxy-hemoglobin/myoglobin concentrations (TotalHb/Mb, OxyHb/Mb, DeoxyHb/Mb), and the slopes of the change in OxyHb/Mb during exercise. SpO2 decreased in H while DR and V.O2 did not differ between the conditions. During exercise, OxyHb/Mb was lower in H than in N, and DeoxyHb/Mb was higher in H than in N. TotalHb/Mb began to increase from the resting level earlier in H. HR was higher during the latter half of the exercise in H. The slopes of the change in OxyHb/Mb were the same in the two conditions. Our results show that low FiO2 decreases SpO2 and muscle oxygenation during maximal isokinetic knee extension. However, low SpO2 and muscle oxygenation did not affect the rates of decline of peak torque. These results suggest that the decline in peak torque occurs for reasons other than O2 availability.
A Facile, Low‐Cost, and Scalable Method of Selective Etching of Semiconducting Single‐Walled Carbon Nanotubes by a Gas Reaction (2008)

A facile, scalable, and low-cost gas-treatment method for selectively etching semiconductor single-walled carbon nanotubes (SWNTs) is developed. Using SO3 gas as the etchant at a temperature of 400 °C, semiconductor SWNTs can be selectively and efficiently removed, and after this gas treatment samples enriched with metallic SWNTs can be obtained.
Application of the CBR method for adding the technological process designing (2016)

The manufacturing process is a very important step in the process of new products creating. The market trends cause that the process must be very flexible to facilitate fast and cost-effective adaptation to changing market conditions. Commonly used CNC machine tools, grouped in flexible production systems significantly facilitate fast production adjusting to these dynamic changes. The programs for CNC machine tools could be easily modified or generated in the CAM class programs. It remains, however, the technological process, which should be planned and continuously optimized with respect to new details being produced. In this paper is proposed the method basing on the engineering knowledge and experience for adding the process of production preparation. The method, developed by authors, is based on the CBR (Case Based Reasoning) technique. CBR is a method of problems solving. It bases on seeking an analogy (similarity) between the task currently being solved, and the earlier tasks that had already been solved. The article presents an algorithm and formalized description of the developed method.
Spontaneous Bilateral Internal Carotid Artery Dissection with Acute Stroke in Young Patients (2006)

We studied the clinical and neuroradiological features of 41 cases with spontaneous bilateral internal carotid artery dissection (ICAD), including 3 cases in our hospital and 38 retrieved from the English literature. Bilateral ICAD accounts for 15.8% of young stroke patients with ICAD in our hospital. The most common presentations are head and/or neck pain, cerebral ischemia, carotid bruit and Horner's syndrome. The cerebral ischemic symptoms are extremely variable in bilateral ICAD, including unilateral hemisphere, bilateral hemisphere or brainstem-like symptoms. Although the underlying pathogenesis remains uncertain, good vascular and clinical outcomes are achieved for spontaneous bilateral ICAD.
Studies of incipient combustion and its detection. Report of investigations 1976 (1976)

The early and reliable detection of the self-heating of combustible substances in mines is of considerable importance to the mining community. This Bureau of Mines report describes the results of a variety of studies of incipient combustion and its detection. Heated samples of coal, wood, and various polymers were used to evaluate the relative sensitivities of several types of detectors. The laboratory results indicate that submicron particulate detection is the most universal and sensitive method. Carbon monoxide detection was as sensitive for pyrolyzing coal, but was relatively insensitive to pyrolyzing wood or plastics. The conventional type of ionization smoke detector was the least sensitive for coal and of intermediate sensitivity for wood and plastics. Self-heating experiments with Pittsburgh Seam coal piles of varying particle sizes gave ignition temperatures of 170C for 4-7micrometers dust, which increased monotonically with particle size. The measured heating rates were compared with data from an adiabatic calorimeter to obtain preexponential rate constants. These varied linearly with the surface area per unit mass of sample.
Treatment of IgM-associated immunoglobulin light-chain amyloidosis with rituximab-bendamustine (2018)

TO THE EDITOR:

Systemic amyloid light-chain amyloidosis (AL) is characterized by deposition of misfolded immunoglobulin light chains within organs. AL with an immunoglobulin M (IgM) monoclonal protein (IgM-AL) accounts for 5% to 7% of AL and exhibits more prevalent lymph node, neuropathic, and lung
A Numerical and Experimental Study on the Effect of the Cone Angle of the Spindle in Murata Vortex Spinning Machine (2008)

To study the effect of the cone angle of the hollow spindle in the nozzle of Murata vortex spinning (MVS) on yarn properties, the k‐ε turbulence model is employed to simulate the airflow patterns inside the different nozzles with different spindle cone angles. A set of corresponding spinning experiments is designed to verify numerical predictions. The simulation results show that some factors, such as the counter-rotating vortex pair (CVP) over the spindle, high supersonic zone in the inlet of the swirling chamber, and the distribution of wall shear stress (WSS) along the outer wall of the spindle caused by variation of the cone angle of the spindle, are significantly related to fluid flow, and consequently to MVS yarn properties. A rational cone angle (Case 2) can form an axisymmetric CVP and high WSS, which can ensure sufficient twisting of the yarn and produce high quality yarn. The experimental results, which yarn properties spun using 100% cotton, 100% polyester, and polyester 70∕cotton 30 blends with different nozzles, are well consistent with the numerical study.
The minimum element of a synthetic peptide required to block prostate tumor cell migration (2006)

Human prostate tumor cell invasion and metastasis are dependent in part on cell adhesion to extracellular matrix proteins and cell migration. We previously identified a synthetic D-amino acid tumor cell adhesion peptide called HYD1 (kikmviswkg) that supported adhesion of tumor cells derived from breast, prostate, ovary and pancreas tissue. Alanine substitution analysis and a peptide deletion strategy were used to determine the minimal element of HYD1 necessary for bioactivity in a prostate cancer cell line called PC3N. Bioactivity was measured by assays of cell adhesion, migration and ERK signaling. The most potent element of HYD1 necessary to support cell adhesion was kmvixw, the block to migration required xkmviswxx and activation of ERK signaling required ikmviswxx. The shortest sequence active in all three assays was iswkg. The HYD1 peptide contains overlapping elements required for adhesion, blocking migration and the activation of ERK signaling. These linear peptide sequences provide the starting point for development of novel compounds to target cancer cell adhesion and migration.

Characterizing memory bottlenecks in GPGPU workloads (2016)

GPUs are often limited by the off-chip memory bandwidth. With the advent of general-purpose computing on GPUs, cache hierarchy has been introduced to filter the bandwidth demand to the off-chip memory. However, the cache hierarchy presents its own bandwidth limitations in sustaining such high levels of memory traffic. In this work, we characterize the bandwidth bottleneck in GPUs present across the memory hierarchy for general-purpose applications. We show that the improvement in performance achieved by mitigating the bandwidth bottleneck in the cache hierarchy can exceed the speedup obtained by a memory system with a baseline cache hierarchy and high bandwidth off-chip memory. We also show that addressing the bandwidth bottleneck in isolation at specific levels can be sub-optimal and can even be counter-productive. Therefore, we show that it is imperative to resolve the bandwidth bottleneck synergistically across different levels of the memory hierarchy.
NeuroMonitor: a low‐power, wireless, wearable EEG device with DRL‐less AFE (2017)

Electroencephalography (EEG) is an effective tool to non‐invasively capture brain responses. Traditional EEG analogue front end (AFE) requires a driven right leg (DRL) circuit that restricts the number of channels of the device. The authors are proposing a new ‘DRL‐less’ AFE design, and have developed a wearable EEG device (NeuroMonitor), which is small, low‐power, wireless, and battery operated. The EEG device with two independent channels was fabricated on an 11.35 cm 2 PCB that contained a system‐on‐a‐chip microcontroller, a low‐noise instrument amplifier, a low‐power Bluetooth module, a microSD, a microUSB, and a LiPo battery. The DRL circuit was eliminated by utilising the high CMRR instrument amplifier with differential inputs, and followed by a modified high‐Q active Twin‐T notch filter (( f c Notch = 60 Hz, − 38 dB). The signal was conditioned with a band‐pass filter composed of a two‐stage 2nd‐order Chebyshev‐I Sallen‐Key low‐pass filter cascaded with a passive 2nd‐order low‐pass filter ( f c LP = 125 Hz) and a 1st‐order passive high‐pass filter ( f c HP = 0.5 Hz). Finally, the signal was amplified to achieve an overall gain of 55.84 dB, and digitised with a 16‐bit delta‐sigma ADC (256 sps). The prototype weighs 41.8 gm, and has been validated against a research‐grade EEG system (Neuroscan).
Historical Drama (1982)

'Historical' is a word which we commonly use, but to confront the historical dramas of Goethe and Schiller, the historical novels of Scott, some of the most complex and representative works of a whole phase of European culture, is to recognise how problematic the term is, how nuanced and inflected by usage and tradition. For we are apt to overlook the fact that before the phase of Enlightenment and Romanticism the writing of history was an unusual form of activity; so that the whole sum of history from Herodotus to Gibbon forms a relatively slight and compact body of knowledge when weighed in the balance with theology and works of a doctrinal nature. It was the Enlightenment of Gibbon and Voltaire that freed history from its subordination to religious concerns, but it was the historical drama of Goethe and Schiller and the historical novel of Scott that served to define what the historical was: they presented it not simply as some generalised concern with the past, but as a complex and concrete thematicising of certain problems in human history. We should never see the historical drama or historical novel as simply fiction plus history: we must acknowledge that in this case literature was the forerunner, articulating forms of awareness that only very much later entered the domain of historiography itself.KeywordsCentralise PowerAesthetic TheoryMoral CorruptionHistorical DramaAncient CustomThese keywords were added by machine and not by the authors.

Reactive Oxygen Species Production by Mitochondria (2009)

Oxidative damage to cellular macromolecules is believed to underlie the development of many pathological states and aging. The agents responsible for this damage are generally thought to be reactive oxygen species, such as superoxide, hydrogen peroxide, and hydroxyl radical. The main source of reactive species production within most cells is the mitochondria. Within the mitochondria the primary reactive oxygen species produced is superoxide, most of which is converted to hydrogen peroxide by the action of superoxide dismutase. The production of superoxide by mitochondria has been localized to several enzymes of the electron transport chain, including Complexes I and III and glycerol-3-phosphate dehydrogenase. In this chapter the current consensus view of sites, rates, mechanisms, and topology of superoxide production by mitochondria is described. A brief overview of the methods for measuring reactive oxygen species production in isolated mitochondria and cells is also presented.
Brushing compliance with a novel integrated power toothbrush and toothpaste oral hygiene system. (2004)

Patient motivation can be an important factor in successful compliance with an oral hygiene program. However, it also can present the most difficulty with such compliance. For example, some conditions, such as gingivitis, may seem nonthreatening, making adherence to recommended regimens especially difficult to attain. A new power toothbrush technology with an integrated toothpaste system has been developed that increases a patient's ability and willingness to adopt recommended regimens. This article reviews this novel technology and reports on a study comparing it to a nonintegrated power toothbrush and regular toothpaste. The features of the novel toothbrush technology also are explained in the context of patient concordance vs patient compliance.
C itrus monstruosa Discrimination among Several C itrus Species by Multivariate Analysis of Volatiles: A Metabolomic Approach (2015)

The origin and taxonomy of Citrus monstruosa (Rutaceae) are currently unknown and thus a nontargeted metabolomic analysis on the flavedo volatiles was performed. Headspace solid-phase micro extraction coupled with gas chromatography analysis was applied to eight Citrus spp. including Citrus monstruosa, and the chemical composition of the volatile organic compounds (VOC) was analyzed to give a chemical comparison between different Citrus species. Forty-four metabolites were detected across the species: several monoterpenes were found in all Citrus spp. and among them limonene comes first in all Citrus spp. ranging from 96.7 to 66.7%. Conversely, some molecules were found to be specific for only a few of the samples. The classical univariate evaluation of the VOC data is unlikely to give objective data for the cultivar classification; a multivariate approach, principal component analysis, is an easy to use, powerful tool. Therefore, a chemometric comparison between chromatographic data of all Citrus spp. was performed with the aim of understanding the role of VOC in the discrimination of the eight studied cultivars. Practical Application A chemometrics' method was applied on the volatiles of eight Citrus spp. including Citrus monstruosa. Results were used to discriminate and classify C. monstruosa from several other Citrus spp. This method may also be used to discriminate other Citrus spp. as well as being applied to the volatiles-based classification of other botanicals.
MRI OF EARLY OSTEONECROSIS OF THE FEMORAL HEAD AFTER TRANSCERVICAL FRACTURE (1996)

We have carried out a prospective study of 17 patients (14 women, 3 men) of mean age 48 years (21 to 76) with transcervical fractures of the femur using MRI to detect early evidence of avascular necrosis of the head. Two fractures were Garden stage I, 12 stage II, and three stage III. We performed internal fixation under radiological control at a mean of five days (2 to 15) after injury using a titanium cannulated cancellous screw or a titanium compression hip screw. MRI was performed at one, six and 12 months and then yearly after operation. T1- and T2-weighted images were obtained by a spin-echo technique. The duration of follow-up of patients who did not subsequently require replacement of the head of the femur was from 2 to 5 years (mean 3.2). One month after operation eight of the 17 hips showed a band of low signal intensity on T1-weighted images and high signal intensity on T2-weighted images indicating lesions in the femoral head away from the fracture line. These were of three types: type I was a small infarct at the superolateral region of the femoral head and was seen in three hips; type II was a shallow lesion from the superolateral region to the fovea of the femoral head (three hips); and type III was a large lesion occupying most of the femoral head (two hips). No further changes were seen in the MRI after six months from operation. Collapse of the femoral head did not occur in the three hips with type-I lesions, but two of the three type-II hips and both type-III hips subsequently collapsed. At the final follow-up the three hips with a type-I lesion and one with a type-II were still asymptomatic but radiography showed sclerosis in the femoral head corresponding to the MRI lesions. The nine hips which showed no changes on MRI at one month had no abnormal findings on physical examination, radiography or MRI at final follow-up.
Simultaneous in situ characterisation of bubble dynamics and a spatially resolved concentration profile: a combined Mach–Zehnder holography and confocal Raman-spectroscopy sensor system (2017)

Abstract. For a reaction between a gaseous phase and a liquid phase, the interaction between the hydrodynamic conditions, mass transport and reaction kinetics plays a crucial role with respect to the conversion and selectivity of the process. Within this work, a sensor system was developed to simultaneously characterise the bubble dynamics and the localised concentration measurement around the bubbles. The sensor system is a combination of a digital Mach–Zehnder holography subsystem to measure bubble dynamics and a confocal Raman-spectroscopy subsystem to measure localised concentration. The combined system was used to investigate the chemical absorption of CO2 bubbles in caustic soda in microchannels. The proposed set-up is explained and characterised in detail and the experimental results are presented, illustrating the capability of the sensor system to simultaneously measure the localised concentration of the carbonate ion with a good limit of detection and the 3-D position of the bubble with respect to the spot where the concentration was measured.
