Improved outcome in Wegener's granulomatosis and microscopic polyangiitis? A retrospective analysis of 95 cases in two cohorts
Mortality rates for Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA) have decreased after the introduction of cyclophosphamide. Standardized mortality ratio (SMR) expresses the overall mortality of patients compared with the general population. The aims of this study were to compare survival in an old and a recent cohort of patients with WG and MPA using SMR and to determine predic
A LiDAR method of canopy structure retrieval for wind modeling of heterogeneous forests
The difficulty of obtaining accurate information about the canopy structure is a current limitation towards higher accuracy in numerical predictions of the wind field in forested terrain. The canopy structure in computational fluid dynamics is specified through the frontal area density and this information is required for each grid point in the three-dimensional computational domain. By using raw
Carotid artery entrapment by the hyoid bone.
We report a patient with a transient ischemic attack presumably caused by an entrapment of the internal carotid artery by the hyoid bone and without a significant carotid artery stenosis. The patient was operated on, with a release of the right internal and external carotid artery and resection of the right greater cornu of the hyoid bone. One year after treatment, the patient has not experienced
Anomalous Zero-Bias Conductance Peak in a Nb-InSb Nanowire-Nb Hybrid Device.
Semiconductor InSb nanowires are expected to provide an excellent material platform for the study of Majorana fermions in solid state systems. Here, we report on the realization of a Nb-InSb nanowire-Nb hybrid quantum device and the observation of a zero-bias conductance peak structure in the device. An InSb nanowire quantum dot is formed in the device between the two Nb contacts. Due to the proxi

Goodpasture's syndrome with concomitant immune complex mixed membranous and proliferative glomerulonephritis
Classical Goodpasture's (GP) syndrome is a monophasic illness characterized by pulmonary hemorrhage and rapidly progressive glomerulonephritis with linear IgG deposition along the glomerular and distal tubular basement membrane and destructive necrotizing diffuse extracapillary crescentic glomerulonephritis. The majority of patients have circulating anti-glomerular basement membrane (GBM) antibodi
Unveiling Nanometer Scale Extinction and Scattering Phenomena through Combined Electron Energy Loss Spectroscopy and Cathodoluminescence Measurements
Plasmon modes of the exact same individual gold nanoprisms are investigated through combined nanometer-resolved electron energy-loss spectroscopy (EELS) and cathodoluminescence (CL) measurements. We show that CL only probes the radiative modes, in contrast to EELS, which additionally reveals dark modes. The combination of both techniques on the same particles thus provides complementary informatio

Theme vowels in North Sámi : Spanning and maximal expression
In North Sámi, certain verbal derivations can be expressed as a change of theme vowel. An investigation of these derivations leads to the conclusion that spanning, i.e. one vocabulary item spelling out two or more terminal nodes, should be included in the toolbox of Distributed Morphology. It follows that com¬petition between vocabulary items is resolved according to the Principle of Maximal Expre
An interaction approach to global sourcing: A case study of IKEA
This study explores the process of global sourcing through a case of the Swedish furnishing retailer IKEA from an interaction perspective. With a point of departure in the streams of existing research on global sourcing and the internationalization process of firms through networks, a research question is proposed concerning supply network interactions as an influence in the global sourcing proces
Optimal single-port matching impedance for capacity maximization in compact MIMO arrays
A complete MIMO system model with compact arrays at both link ends containing arbitrary matching networks is presented based on a Z-parameter approach. The complete channel matrix including the coupling effect is also presented. Utilizing this system model, the optimum single-port matching impedance for capacity maximization is derived for a 2 × 2 MIMO system with coupling at the receivers only. A
Introduction of total knee arthroplasty in Lithuania
Background and purpose We have previously reported that the first 10 years of hip arthroplasty in Lithuania resulted in a higher cumulative revision rate than that observed in Sweden. We thus compared the corresponding results after introduaction of total knee replacement in Lithuania. Methods The 10-year revision rate for the first 595 primary ScanKnee arthroplasties inserted in Klaipeda, Lithuan

Intensity dependence of laser-assisted attosecond photoionization spectra
We study experimentally the influence of the intensity of the infrared (IR) probe field on attosecond pulse train (APT) phase measurements performed with the RABITT method (Reconstruction of Attosecond Beating by Interference in Two-Photon Transitions). We find that if a strong IR field is applied, the attosecond pulses will appear to have lower-than-actual chirp rates. We also observe the onset o
Effects of differences in postprandial glycaemia on cognitive functions in healthy middle aged subjects
Objective: To find useful methods for the studies of cognitive function during a postprandial period, and to use these methods to evaluate function after test meals differing in post meal glycaemia. Subjects/Methods: Forty healthy volunteers aged 49–70 years were studied. A glucose solution (glucose 50 g) was provided through either a bolus or sipping regimen at breakfast to simulate a high-GI or
Three-dimensionally preserved integument reveals hydrodynamic adaptations in the extinct marine lizard ectenosaurus (reptilia, mosasauridae).
The physical properties of water and the environment it presents to its inhabitants provide stringent constraints and selection pressures affecting aquatic adaptation and evolution. Mosasaurs (a group of secondarily aquatic reptiles that occupied a broad array of predatory niches in the Cretaceous marine ecosystems about 98-65 million years ago) have traditionally been considered as anguilliform l

High resolution experimental measurement of turbulent flow field in a high pressure homogenizer model and its implications on turbulent drop fragmentation
Particle image velocimetry is performed on a model of a high pressure homogenizer, scaled for qualitative similarity of the one phase turbulent flow field in a production scale homogenizer. Flow fields in gap entrance, gap and gap outlet chamber are obtained with high resolution. The measurements show gap flow development and formation of a turbulent wall adherent jet when exiting into the outlet
