Current time-resolution-limited dynamic measurements clearly show the need for improved techniques to access processes on the sub-10-femtosecond timescale. To access this regime, we have designed and constructed a state-of-the-art time-resolved magneto-optic Kerr effect apparatus, based on a new dual-color scheme, for the measurement of ultrafast demagnetization and precessional dynamics in magnet
The purpose of this research was to investigate the geometrical accuracy of magnetic resonance (MR) images used in the radiation therapy treatment planning for lung cancer. In this study, the capability of MR imaging to acquire dynamic two-dimensional images was explored to access the motion of lung tumors. Due to a number of factors, including the use of a large field-of-view for the thorax, MR i
This paper makes a case for using cost effectiveness (as opposed to efficiency) as key criterion when designing support policies for electricity generation from renewable energy sources in coexistence with an emissions trading scheme. Using the EU ETS and the German feed-in tariff system as examples, arguments against a stand-alone ETS are presented and necessary conditions for cost-effective supp
Background: Ultraviolet (UV)-curing nail polishes based on acrylates or methacrylates are currently also available for non-professional use. The Swedish Medical Products Agency recently prohibited one brand of UV-curing polish, because several consumers reported undesirable effects after using it. Objectives: To investigate whether consumers with undesirable effects after using the UV-curing nail
In this paper, we study the block error rate (BLER) performance of spatially coupled low-density parity-check (SC- LDPC) codes using a sliding window decoder suited for streaming applications. Previous studies of SC-LDPC have focused on the bit error rate (BER) performance or the frame error rate (FER) performance over the entire length of the code. Here, we consider protograph-based constructions
In this article, we argue for a conceptual move from family-centred care (FCC) to a child-centred care approach and the implications for clinical nursing practice. Firstly, we argue that the parents and professional dominance constructs an asymmetric relationship towards the child, which may take away the focus from the child; Secondly, we need to renew efforts to promote the fundamental principle
High temperatures have a direct impact on body functions. Heat waves increase mortality risks due to myocardial infarction, stroke, and pulmonary disease. Cold temperatures also increase mortality, but with a longer latency. A recent study found only a small difference between the minimal mortality temperature (MMT) and the temperatures at which mortality rose steeply, although the majority of dea
A complete architecture with transistor level simulation is presented for a low power analog convolutional decoder in 65 nm CMOS. The decoder core operates in the weak inversion (sub-VT) and realizes the BCJR decoding algorithm corresponding to the 4-state tail-biting trellis of a (7,5) convolutional code. The complete decoder also incorporates serial I/O digital interfaces and current mode differ
Internal return migration has received limited attention in most western countries, despite studies attesting to its potential for helping understand population redistribution. This paper compares differences in self-reported motives for migration between return and non-return migrants. Particular attention is paid to differences in individual characteristics and in the types of places these two m
Newborn infants have pulmonary disorders with abnormal gas distribution, e. g. respiratory distress syndrome. Pulmonary radiography is the clinical routine for diagnosis. Our aim was to investigate a novel non-invasive optical technique for rapid non-radiographic bedside detection of oxygen gas in the lungs of full-term newborn infants.
Background: The use of drugs for migraine during pregnancy may have adverse effects on delivery outcome, and warnings exist for such drugs regarding use during pregnancy. Most information in the literature concerns triptans. Objective: The aim of the study was to describe the delivery outcome when a woman had used drugs for migraine during pregnancy. Study Design: A register study where exposure f
To evaluate construct validity, internal consistency and inter-rater reliability of the Posture and Postural Ability Scale for children with cerebral palsy.
Background/Aims: Two differently charged polypeptides, poly-L-lysine (PL) and poly-L-glutamate (PG), have previously been shown to reduce postoperative intra-abdominal adhesions. This study aims to investigate the possible toxic effects and to establish a lowest effective antiadhesive dose. Methods: 152 mice were investigated with a well-known adhesion model and given different concentrations of t
In this letter, a magnetic dipole (M-dipole) and an electric dipole (E-dipole) are designed to form a collocated polarization-diversity-based dual-antenna system. The M-dipole is a modified shielded loop with multiple feed, and the E-dipole is a traditional λ/2 dipole. Measured results show that both radiators have ideal impedance matching and port isolation and identical omnidirectional pattern w
distribution G on [math not displayed] is called matrix-exponential if the density has the form αeTz s where α is a row vector, T a square matrix and s a column vector. Equivalently, the Laplace transform is rational. For such distributions, we develop an operator calculus, where the key step is manipulation of analytic functions f(z) extended to matrix arguments. The technique is illustrated via
