The Aw–Rascle–Zhang traffic model, a model of sedimentation, and other applications lead to nonlinear (Formula presented.) systems of conservation laws that are governed by a single scalar system velocity. Such systems are of the Temple class since rarefaction wave curves and Hugoniot curves coincide. Moreover, one characteristic field is genuinely nonlinear almost everywhere, and the other is lin
We have investigated strained GaAs-GaInP core-shell nanowires using transmission electron microscopy and nanofocused scanning X-ray diffraction. Nominally identical growth conditions for each sample were achieved by using nanoimprint lithography to create wafer-scale arrays of Au seed particles. However, we observe large individual differences, with neighboring nanowires showing either straight, b
Blood transfusions were dangerous and prohibited, until medicine developed modern techniques in the middle of the last century. Multi-trauma patients often present hard-to-identify multifactorial coagulopathies which should be recognized and treated before a transfusion is envisaged.
PURPOSE: To investigate assumed benefits of heparin coated cardiopulmonary bypass systems from standard non-coated CBP systems in unstable angina patients with preoperative heparinisation. STUDY DESIGN: Coagulation, complement, cytokine and Sonoclot parameters, were analyzed before total heparinisation prior to surgery, during cardiopulmonary bypass, after protamine to 48 hours after surgery. MATE
OBJECT: Subcutaneously intermittent administration of low molecular weight heparin (LMWH-Fragmin®) - (120IU/kgx2 BW) - in unstable angina was introduced clinically during the last year at our Hospital, after reports of the FRISC and FRIC studies as an alternative to continous infusion of standard heparin. In such patients with need for CABG, no data on haemostasis or anticoagulation during CBP had
OBJECT: Subcutaneously intermittent administration of low molecular weight heparin (LMWH-Fragmin®) - (120IU/kgx2 BW) -in unstable angina has been introduced clinically during the last year, after reports of the FRISC and FRIC studies as an alternative to continous infusion of standard heparin. Fragmin® could possible endanger postoperative haemostasis after CABG due to uncomplete reversal of anti-
A highly tunable linear triple quantum dot (TQD) device is realized in a single-crystalline pure-phase InAs nanowire using a local finger gate technique. The electrical measurements show that the charge stability diagram of the TQD can be represented by three kinds of current lines of different slopes and a simulation performed based on a capacitance matrix model confirms the experiment. We show t
The Biopython Project is a long-running distributed collaborative effort, supported by the Open Bioinformatics Foundation, which develops a freely available Python library for biological computation [1]. We present here details of the Biopython releases since BOSC 2016, namely Biopython 1.68, 1.69 and 1.70. Together these had 82 named contributors including 51 newcomers which reflects our policy o
Effective monitoring of flying insects is of major societal importance in view of the role of insects as indispensable pollinators, destructive disease vectors and economically devastating agricultural pests. The present paper reports on monitoring of flying agricultural pests using a continuous-wave lidar system in a rice-field location in Southern China. Using a Scheimpflug arrangement, range re
In the present study the geographical distribution, abundance and composition of Gambierdiscus was described over a 600 km longitudinal scale in the Canary Islands. Samples for cell counts, isolation and identification of Gambierdiscus were obtained from five islands (El Hierro, Tenerife, Gran Canaria, Fuerteventura and Lanzarote). Average densities of Gambierdiscus spp. between 0 and 2200 cells g
In the arid irrigated lands, understanding the impact of shallow groundwater fluctuation on soil salinization has become crucial. Thus, investigation of the possible options for maintaining the groundwater depth for improving land productivity is of great importance. In this study, under saline irrigation condition, the effects of shallow groundwater depth on water and salt dynamics in the root-zo
Stroke recovery research involves distinct biological and clinical targets compared to the study of acute stroke. Guidelines are proposed for the pre-clinical modeling of stroke recovery and for the alignment of pre-clinical studies to clinical trials in stroke recovery.
We present results from two experiments that provide the first quantification of inter-particle force networks in stiff, 3D, opaque granular materials. Force vectors between all grains were determined using a mathematical optimization technique that seeks to satisfy grain equilibrium and strain measurements. Quantities needed in the optimization - the spatial location of the inter-particle contact
The rheology of dense granular flows is studied numerically in a shear cell controlled at constant pressure and shear stress, confined between two granular shear flows. We show that a liquid state can be achieved even far below the yield stress, whose flow can be described with the same rheology as above the yield stress. A non-local constitutive relation is derived from dimensional analysis throu
In this work, we extend the popular sparse iterative covariance-based estimator (SPICE) by generalizing the formulation to allow for different norm constraint on the signal and noise parameters in the covariance model. For any choice of norms, the resulting generalized SPICE method enjoys the same benefits as the regular SPICE method, including being hyperparameter free, although the choice of nor
In this paper, we present a technique for reducing the size of the dictionary in sparse signal reconstruction by formulating an initial dictionary containing elements that spans bands of the considered parameter space. We allow for the use of this banded dictionary in a first-stage estimation procedure, in which large parts of the parameter space is discarded for further analysis, thereby reducing
Purpose: The purpose of this paper is to investigate how modern network video technology could be used to improve different warehouse types and operations and how barriers may prevent its implementation. Design/methodology/approach: An exploratory multiple-case study with nine case companies was conducted, including on-site visits, interviews, questionnaires and a workshop. Findings: The authors i
