Joint processing of common-mode (CM) and differential-mode (DM) signals in wireline transmission can yield significant improvements in terms of throughput compared to using only the DM signal. Recent work proposed the employment of an adaptive CM-reference-based interference canceller and reported performance improvements based on simulation results. This paper presents a thorough investigation of
A number of reports have been examined of tests undertaken by FRS and by FIRTO for the purpose of studying the behaviour of sprinkler systems in controlling fires in piles of stacked cardboard cartons. Mean speeds of the rising flame tip have been estimated and found to be very variable. Typically if ignition is on the vertical outside "face" speeds are 1-3 cm/sec. Ignition in a "face" is typicall
To evaluate the expression and protein levels of antioxidant enzymes in the rat retina exposed to oxidative stress induced by ischemia-reperfusion injury. Retinal ischemia was induced in female Wistar rats by ligation of the optic nerve and vessels behind the left eye bulb, and was followed by reperfusion for 0, 3, 6, or 24 hours. The right eye served as control. RNA and protein were extracted sim
Popular Abstract in Swedish Kraven på fordonstillverkare att tillverka motorer med låga avgasemissioner kommer att bli betydligt hårdare i framtiden. När det gäller dieselmotorer är det främst utsläppen av partiklar och kväveoxider som utgör de verkliga utmaningarna. Idag finns avgasreningsteknik för att kraftigt reducera dieselmotorns utsläpp, men fortsatt minskning av bildningen av skadliga och Diesel engine developers are facing major challenges when meeting future demands on NOx and particulate emissions. The exhausts after treatment systems are rapidly improving and the technologies available in a few years will be capable of cutting emission levels close to the demanded levels. However, in order to reach the low emissions required in a long-lasting, cost effective way, the potential
Studies of research utilization have not taken up Janet Weiss's challenge: to make local research utilization policies understandable in institutional contexts. This article presents research from three different policy sectors: the social services; building and planning; and the working life area. The results of the studies are presented as typical patterns of utilization. The purpose of the arti
We investigate spin-dependent transport properties of two-dimensional electron systems modulated by both the stray field from a ferromagnetic metal (FM) stripe and the electrostatic potential (EP) provided by two normal metal Schottky stripes which sandwich the FM stripe. The EP consists of a single barrier and a single well. By switching the gate voltages applied to the Schottky stripes, the barr
Seventeen globular clusters in the Large and Small Magellanic Clouds were observed in the mid-infrared wavelength region with the ISOCAM instrument on board the Infrared Space Observatory (ISO). Observations were made using the broadband filters LW1, LW2, and LW10, corresponding to the effective wavelengths of 4.5, 6.7, and 12 mum, respectively. We present the photometry of point sources in each c
A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for soft tissue sarcomas (STS) is based on data from five randomized trial
ErbB1 and ErbB2 receptors are well-characterized targets for anticancer drugs, but the clinical relevance of the related ErbB4 receptor is unknown. Here, we have assessed the clinical significance of the proteolytically cleavable ErbB4 isoforms in breast cancer patients and investigated their functions in vitro. The expression of transcripts encoding the cleavable ErbB4 isoforms associated with es
Background: Firm recommendations about the way thiopurine drugs are introduced and the use of thiopurine methyltransferase (TPMT) and metabolite measurements during treatment in inflammatory bowel disease (IBD) are lacking. Aim: To evaluate pharmacokinetics and tolerance after initiation of thiopurine treatment with a fixed dosing schedule in patients with IBD. Patients: 60 consecutive patients wi
High resolution transmission electron microscopy and digital image processing has been used to investigate the structure and properties of inorganic materials. The image processing was performed with the programming language Semper. All routines are listed in the appendix. The local order in the disordered mineral blatterite was investigated, and was found to extend over several unit cells. The
This book is an analysis of the way in which Tanzanian Roman Catholic professor Charles Nyamiti has attempted to combine African traditions and values with neo-Scholastic theology and philosophy. The outcome of the analysis is that in this attempt, Nyamiti needs to rework considerably African traditions in order that they will not collide with "philosophia perennis". Additionally, he deals with th
When a manipulator interacts with objects with poorly damped oscillatory modes, undesired oscillations and bouncing may result. In this paper, we present a method for observer-based control of a rigid manipulator interacting with an environment with linear dynamics.The controller injects a desired damping into the environment dynamics, using both visual-and force sensing for stable control of the
Popular Abstract in Swedish För att lungorna ska utvecklas normalt hos ett däggdjursfoster, måste lungorna vara vätskefyllda. Det har länge varit kännt att denna vätska produceras av lungorna själva, genom s k klorid-sekretion. Vid födelsen måste det nyfödda fostret börja andas och därför är det ytterst viktigt att lungorna snabbt töms på vätskan som fanns där under fosterutvecklingen. Detta sker Alveolar fluid clearance is driven by active absorption of Na+ across the alveolar epithelium. Development and hormonal regulation of alveolar fluid clearance over 1 hour was studied by instillation of a protein-containing, isosmolar fluid into lungs of fetal, newborn, and adult guinea pigs. After 1 hour, a sample of remaining alveolar fluid was collected and the change in protein concentration wa
