Stent-Sizing With Intravascular Ultrasound ontributes to Complete Neointimal Coverage fter Sirolimus-Eluting Stent Implantation ssessed by Angioscopy

esults “Complete” coverage was identified in 10 (36%), and “incomplete” coverage was identified n 18 (64%). Time from the stenting to angioscopy as well as the lesion and procedural characterisics were similar between the complete and incomplete coverage groups. The IVUS parameters were lso similar, except for the final minimum stent cross-sectional area (CSA) (7.0 1.8 mm in comlete vs. 5.3 1.9 mm in incomplete, p 0.02) and lumen CSA at the distal reference site (6.1 .4 mm in complete vs. 4.9 1.2 mm in incomplete, p 0.02). The ratio of the stent area to the essel area was significantly larger in the complete coverage than in the incomplete coverage group 0.52 0.11 vs. 0.39 0.09, p 0.002).
Analysis and control of input power factor in indirect matrix converter

The topology and control method of indirect matrix converter (IMC) is discussed in the paper. The space vector pulse width modulation (SVPWM) is employed on both of the rectifier stag and the inerter stage. The adjustment method of input power factor is presented based on the input current SVPWM of the rectifier stage. According to the polarity requirement of dc-link voltage, the regulation range of input power factor angle is determined. In addition, the influence of input LC filter on input power factor is analyzed. The calculation formula of input power factor angle at the grid side is presented. Simulation and experimental results validate the theoretical analysis.
An analytical method for determining circuit parameter of a solid rotor induction motor

This paper presents an analytical method for prediction of equivalent circuit parameter of a solid rotor induction motor with smooth surface. The solid rotor induction motor is similar to a linear induction motor in electromagnetic properties. Therefore, the method of performance calculation for LIM can be applied for the solid rotor induction motor. On the principle of complex power from the equivalent circuit identical to that from electromagnetic field, we develop an analytical model based on 2D polar coordinates and account for the influence of nonlinearity and hysteresis.
Antistatic nurses ’ aprons may contribute to a reduction of hospital infection in isolation wards

In the past, nurses’ cotton uniforms have been implicated in the spread of microorganisms and this led to the widespread use of disposable plastic aprons. However, plastic is notorious in acquiring static electric charge which is able to attract airborne micro-organisms. In this study, five different types of ordinary and antistatic nurses’ plastic aprons were tested both electrostatically and bacteriologically. The purpose was to investigate whether antistatic aprons may constitute an improved barrier to the spread of micro-organisms, particularly in isolation wards where immuno-compromised patients are more susceptible to infecting organisms. Results showed that one antistatic apron from five types tested exhibited a 38% reduction in bacteria attracted onto its surface compared with the white plastic aprons currently in use. We suggest that antistatic aprons may contribute to a reduction in hospital infections, particularly in isolation wards such as those in bone marrow transplant units.
On the bi-elliptical toroidal helical antenna problem

By eliminating the fundamental apriori assumption typical of previously reported formulations of bi-elliptical toroidal helical antenna (THA) problem, that the antenna will operate only at one or more of its three characteristic resonance frequencies, this paper describes a formulation of the problem in a vector potential approach, with basis in the derivation of a Green's function appropriate to the antenna geometry as starting point. Exact closed form expressions are derived for the radiation fields of the THA, and these expressions are shown to represent a general case of certain results reported in the open literature, as special cases. An important contribution of the derivation is that for the first time to the best of our knowledge, analysis is able to identify distinct contributions to the far-zone fields attributable to the main loop and the poloidal loops of the THA. Computational results for the THA operated in the dipole mode are presented in graphical formats displaying separate contributions of the main and poloidal loops, as well as their resultants, to the radiations fields. In the polar direction, radiation fields from these loops have similar shapes; though that due to the main loop is some 20 times larger in magnitude than that due to the poloidal loops. The resultant radiation field in the polar direction has the omnidirectional pattern characteristic of the dipole antenna. On the other hand, the phi-component of the radiation field is characterized by contributions from the main loop that are some 800 times greater in magnitude than those from the poloidal loops. And indeed, the computational results suggest that for the THA operated in the dipole mode, the phi-component in the far-zone dominates, with the net effect that that the THA's radiation field is directional, with the cardioid shape due to the dominant phi-component of the main loop.
Script and Text in Time and Space

The project Script and Text in Time and Space will create a new foundation for working with medieval Danish texts by creating and deepening fundamental knowledge about the development of medieval script in Denmark as well as the dating and localization of relevant text bearing objects (manuscripts and other document types). The project is placed in the field of Digital Humanities, meaning that digital tools and general guidelines for editing and analysing primary sources play a central role. Script – the written manifestation of language – is key to most analyses of medieval language and literature as well as history and culture in general. In fact, it is usually because of script and the language it preserves that a primary source can be placed in time and space. In recent years there has been an increased interest in the transmission and reception of historical texts and documents, which renews the need for and underlines the importance of detailed studies in the history and origin of these sources. Despite dating and localization of a written text based on the language and script being central to philological studies, there are surprisingly few tools and fundamental reference points available when it comes to Danish script. Particularly compared to the substantial work on West Norse, little systematic analysis has been conducted on Danish medieval texts, including the circumstances of their production and the development of the script. The project addresses this issue by conducting both qualitative and quantitative studies of the relevant features in medieval Danish charters (official documents) from the thirteenth to the sixteenth centuries. Unlike almost all other written
Numerical study of the instability of the Hartmann layer

Direct numerical simulation is applied to investigate instability and transition to turbulence in the flow of an electrically conducting incompressible fluid between two parallel unbounded insulating walls affected by a wall-normal magnetic field (the Hartmann flow). The linear stability analysis of this flow provided unrealistically high critical Reynolds numbers, about two orders of magnitude higher than those observed in experiments. We propose an explanation based on the streak growth and breakdown mechanism described earlier for other shear flows. The mechanism is investigated using a two-step procedure that includes transient growth of two-dimensional optimal perturbations and the subsequent three-dimensional instability of the modulated streaky flow. In agreement with recent experimental investigations the calculations produce a critical range between 350 and 400 for the Hartmann thickness based Reynolds number, where the transition occurs at realistic amplitudes of two- and three-dimensional perturbations.
Combined atmospheric oxidant capacity and increased levels of exhaled nitric oxide

Nitrogen dioxide and ozone are two interrelated oxidative pollutants in the atmosphere. Few studies have evaluated the health effects of combined oxidant capacity (Ox). We investigated the short-term effects of Ox on fractional exhaled nitric oxide (FeNO), a well-established biomarker for airway inflammation, in a group of chronic obstructive pulmonary disease patients. Real-time concentrations of Ox were obtained by calculating directly the sum of nitrogen dioxide and ozone. Linear mixed-effect models were applied to explore the acute effects of Ox on FeNO levels. Short-term exposure to Ox was significantly associated with elevated FeNO. This effect was strongest in the first 24 h after exposure, and was robust to the adjustment of PM2.5. A 10 μg m−3 increase in 24 h average concentrations of Ox was associated with 4.28% (95% confidence interval: 1.19%, 7.37%) increase in FeNO. The effect estimates were statistically significant only among males, elders, and those with body mass index ≥24 kg m−2, a comorbidity, higher educational attainment, or moderate airflow limitation. This analysis demonstrated an independent effect of Ox on respiratory inflammation, and suggested that a single metric Ox might serve as a preferable indicator of atmospheric oxidative capacity in further air pollution epidemiological studies.
The rest-frame optical colours of 99 000 sloan digital sky survey galaxies

We discuss the colours of 99 088 galaxies selected from the Sloan Digital Sky Survey (SDSS) Data Release 1 'main' spectroscopic sample (a flux-limited sample, r(Pet) <17.77, for 1360 deg(2)) in the rest-frame Stromgren system (uz, vz, bz, yz). This narrow-band (similar to 200 angstrom) photometric system, first designed for the determination of effective temperature, metallicity and gravity of stars, measures the continuum spectral slope of galaxies in the rest-frame 3200-5800 angstrom wavelength range. We synthesize rest-frame Stromgren magnitudes from SDSS spectra, and find that galaxies form a remarkably narrow locus (similar to 0.03 mag) in the resulting colour-colour diagram. Using the Bruzual & Charlot population-synthesis models, we demonstrate that the position of a galaxy along this locus is controlled by metallicity and age of the dominant stellar population. The distribution of galaxies along the locus is bimodal, with the local minimum corresponding to an similar to 1-Gyr-old single stellar population. The position of a galaxy perpendicular to the locus is independent of metallicity and age, and reflects the galaxy's dust content, as implied by both the models and the statistics of IRAS detections. Comparison of the galaxy locus in the rest-frame Stromgren colour-colour diagram with the galaxy locus in the H delta(A)-D(n)(4000) diagram, utilized by Kauffmann et al. to estimate stellar masses, reveals a tight correlation, although the two analysed spectral ranges barely overlap. Furthermore, the rest-frame r-i colour (5500-8500 angstrom wavelength range) can be 'predicted' with an rms of 0.05 mag using the rest-frame Stromgren colours. Overall, the galaxy spectral energy distribution in the entire ultraviolet to near-infrared range can be described as a single-parameter family with an accuracy of 0.1 mag, or better. This nearly one-dimensional distribution of galaxies in the multidimensional space of measured parameters strongly supports the conclusion of Yip et al., based on a principal component analysis, that SDSS galaxy spectra can be described by a small number of eigenspectra. Furthermore, the rest-frame Stromgren colours correlate tightly with the classification scheme proposed by Yip et al. based on the first three eigenspectra. Apparently, the contributions of stellar populations that dominate the optical emission from galaxies are combined in a simple and well-defined way. We also find a remarkably tight correlation between the rest-frame Stromgren colours of emission-line galaxies and their position in the Baldwin-Phillips-Terlevich diagram. These correlations between colours and various spectroscopic diagnostic parameters support earlier suggestions that rest-frame Stromgren photometry offers an efficient tool to study faint cluster galaxies and low surface brightness objects without performing time-consuming spectral observations.
Reduced voltage combined AC motor and drive system for safe electric vehicle

This paper presents the design, analysis and implementation of a proposed combined three phase induction motor and its drive system to meet the demand of low-voltage electrical system for hybrid and electric cars, avoiding the high voltage human risks, expensive and complex requirements of the higher voltage insulation and power electronic devices. The development of electric vehicle technologies has been reviewed. A conventional 220V 3-ph induction motor has been rewound in order to get the required 48V 3-ph motor. A comparison between the old motor and the rewound motor has been theoretically and practically carried out including different characteristics. Design and simulation analysis of different control cards have been carried out using PSpice software while the overall drive system performance has been simulated using Simulink under Matlab package. The proposed setup has been practically implemented using commercial available components. Different practical waveforms have been obtained for different operation modes, showing the effectiveness of the proposed setup as a reduced voltage speed control drive system suitable for safe electric vehicle applications.
Mycobacterium avium‐triggered diseases: pathogenomics

The species Mycobacterium avium includes several subspecies representing highly specialized avian and mammalian pathogens, non‐obligatory pathogens of immune compromised humans and saprophitic organisms. Recently obtained information concerning the diversity of M. avium genomic structures not only clarified phylogenic relationships within this species, but began to shed light on the question of how such closely related microorganisms adapt to the occupation of distinct ecological niches. In this review we discuss specific features of M. avium genetic composition, as well as genetic and molecular aspects of M. avium hominissuis (MAH)‐triggered disease pathogenesis, including virulence, penetration, immune response manipulation and host genetic control.
Accurate multi-view stereo by selective expansion

We present a multi-view stereo method for robust and efficient dense modeling based on selective expansion. The core is that the proposed method progressively refines pixel depths by expanding pixels that are selected with small photo-consistency costs to their neighbors, which is more efficient than conventional PatchMatch methods. Besides, a depth refinement process including mapping and filtering against neighboring frames is used to further improve the accuracy of estimated depths. In contrast to previous methods, our method has low computational complexity and doesn't need any optimization algorithm. The accuracy of proposed method is evaluated quantitatively and qualitatively on benchmark data.
$N \times N$ Cyclic-Frequency Router With Improved Performance Based on Arrayed-Waveguide Grating

We have developed an NxN cyclic-frequency router with improved performance by employing two types of modified configuration; a uniform-loss and cyclic-frequency (ULCF) arrayed-waveguide grating (AWG) and an interconnected multiple AWG. We have demonstrated a compact 50-GHz-spacing 64x64 ULCF-AWG router with low and uniform insertion losses of 5.4-6.8 dB and frequency deviations from the grid of less than plusmn8 GHz. We have also demonstrated a 100-GHz-spacing 8x8 interconnected multiple-AWG router with a practical configuration, very low and uniform insertion losses of 2.3-3.4 dB, and frequency deviations from the grid of less than plusmn6 GHz. We discuss the suitable or realizable scale N of the two types of routers by comparison with a conventional AWG router in terms of optical and dimensional performance and productivity.

Setting up of Management Information Subsystem of Searching, Analysis and Utilization: A Case Study

The popularization and application of management information system (MIS) is an important mark of the information age, which mainly includes two subsystems: search system and system of analysis and utilization. Taking Haier Group for example, the thesis analyses its construction experience in building MIS and information competition rules that it contains. Haier's experience has fully proved that MIS' integration is not only a platform for integration of subsystems, but also the data integration that subsystem could achieve timely management, play and explore the overall effectiveness of information system.
CCK2 receptors are necessary for the differentiation and proliferation of ECL cells in mouse and rat stomach

ECL cells in the oxyntic mucosa of the mouse and rat stomach express CCK2 receptors, which enable them to respond to gastrin by the production and release of histamine. We have studied CCK2 receptor-deficient mice and rats subjected to pharmacological CCK2 receptor blockade in an attempt to demonstrate the importance of gastrin signaling for ECL-cell differentiation and proliferation. In CCK2 receptor knockout mice, the ECL cells were replaced by a novel endocrine-like cell type lacking histamine and histidine decarboxylase but retaining pancreastatin and vesicle monoamine transporter type 2 (VMAT2). Ultrastructurally, they were characterized by the presence of small dense-core granules and microvesicles and by the absence of the secretory vesicles that are a hallmark feature of wild-type ECL cells. Upon pharmacological CCK2 receptor blockade, the ECL cells became small and inactive, although unchanged in number. By immunocytochemistry (histamine, pancreastatin and VMAT2) and electron microscopy (secretory vesicles) they remained recognizable as ECL cells; their proliferation in response to hypergastrinemia was prevented.

Out of the Frying Pan and into the Mixing Bowl: Category Grading and the Adoption of Novel Practices

Given that recent research has found that the meanings managers attribute to novel practices are crucial to understanding their adoption, we ask how institutional processes shape the way managers understand novel practices, and how that understanding affects adoption behaviour. In particular, we focus on how managers choose between component practices within a management practice (i.e. between members within a category). We argue, consistent with research in linguistics and anthropology, that categories are graded--that some members represent the category better than others. We go further to argue that the grading affects the value that participants attribute to category members. We build a model of the way processes of theorization and inter-organisational monitoring will grade categories in a field, and argue that, at any point in time, later adopters are more likely to have adopted central members of the category than earlier adopters. We test the resultant propositions by examining the adoption of Manufacturing Best Practice programs in Australia and New Zealand. Our data support our arguments regarding theorization, but not inter-organisational monitoring.
ERRATUM: Relaxation of a moving contact line and the Landau-Levich effect

The dynamics of the deformations of a moving contact line is formulated. It is shown that an advancing contact line relaxes more quickly as compared to the equilibrium case, while for a receding contact line there is a corresponding slowing down. For a receding contact line on a heterogeneous solid surface, it is found that a roughening transition takes place which formally corresponds to the onset of leaving a Landau-Levich film. We propose a phase diagram for the system in which the phase boundaries corresponding to the roughening transition and the depinning transition meet at a junction point, and suggest that for sufficiently strong disorder a receding contact line will leave a Landau-Levich film immediately after depinning.
Adaptive tracking control of a mobile manipulator

In this paper, we propose a computed torque controller for a dynamic model of nonholonomic mobile manipulator with bounded external disturbances in order to treat the adaptive tracking control. Firstly, a velocity controller is designed for the kinematic steering system. Secondly, a computed torque controller is designed such that the mobile manipulator velocity converges to the desired velocity controller deduced from the first step. In particular, the mobile manipulator can globally follow any path such as a straight line or a circle. Simulation results are given to demonstrate the effectiveness of the proposed controller.
Design of a novel planar Bulter matrix beamformer with two-axis beam-switching capability

By employing one microstrip patch array and one single-conductor microstrip leaky-wave array on the same substrate, a novel planar Bulter matrix beam-forming array that can switch beams in two orthogonal axes is proposed in this paper. Numerical simulation and experimental results are shown to demonstrate its two-axis beam-switching capability. With its printed circuit form, it is very suitable for integration into modern wireless communication systems with smart antenna techniques.
