Increasing soft error rates for semiconductor devices manufactured in later technologies enforce the usage of fault tolerant techniques such as Roll-back Recovery with Checkpointing (RRC). As RRC introduces time overhead that increases the completion (execution) time, time constraints (deadlines) might be violated. This is a drawback for a class of computer systems where the correct operation is d
Background: Day centres are central for community participation among people with mental health problems. Understanding day centre attendees' occupational engagement is therefore important. Method:A total of 88 people from six day centres in four municipalities in southern Sweden completed a time-use diary, recording their occupational engagement during the most recent day at the day centre. The t
Chronic oro-facial pain conditions such as persistent idiopathic facial pain (PIFP), atypical odontalgia (AO) and burning mouth syndrome (BMS), usually grouped together under the concept of idiopathic oro-facial pain, remain a diagnostic and therapeutic challenge. Lack of understanding of the underlying pathophysiological mechanisms of these pain conditions is one of the important reasons behind t
The cross section for the diffractive deep-inelastic scattering process ep -> eXp is measured, with the leading final state proton detected in the H1 Forward Proton Spectrometer. The data sample covers the range x(P) < 0.1 in fractional proton longitudinal momentum loss, 0.1 < vertical bar t vertical bar < 0.7 GeV2 in squared four-momentum transfer at the proton vertex and 4 < Q(2) < 700 GeV2 in p
This paper describes a highly digitized direct conversion receiver of a single-chip quadruple-band RF transceiver that meets GSM/GPRS and EDGE requirements. The chip uses an advanced 0.25-mum BiCMOS technology. The I and Q on-chip fifth-order single-bit continuous-time sigma-delta (SigmaDelta) ADC has 84-dB dynamic range over a total bandwidth of +/-135 kHz for an active area of 0.4 mm(2). Hence,
Stable carbon isotopes play an important role in the interpretation of biological activity, particularly when the fossil record is studied. In combination with morphological and chemical data, isotopic information can be useful in paleontology and astrobiology. In this paper the development of a microanalytical ion beam system for the measurement of the carbon isotope ratio with high spatial resol
Most patients referred to physiotherapy with low back pain are without a precise medical diagnosis. Identification of subgroups of non-specific low back pain patients may improve clinical outcomes and research efficiency. A pathoanatomic classification system has been developed, classifying patients with non-specific low back pain into 12 different syndromes and three subcategories based on histor
Issue of study: There is no clear framework for IPR negotiation to support the establishment of I-U collaboration by balancing their competing interests. For I-U collaborations within the same country, several sets of guidelines have been produced to emphasize IPR-issues in R&D collaborations. These have helped to increase awareness, but corporations and universities still report problems when
The paper deals with the question to what extent tax incentives especially designed to promote research and development are compatible with European Union Law. Therefore tax incentives are analysed with special regard to the Fundamental Freedoms and the State aid provision. It can be found that legislators have three basic possibilities given by European Union Law, which differ in the freedom of d
Photoionisation dynamics occurring in Ar and N2O upon the absorption of soft X-ray radiation, have been studied through the extraction of the beta parameter from the angular distributions of Ar 2p 3/2 and N2O Nt 1s photoelectrons by a means of Velocity Map Imaging Spectroscopy. The results of beta determined in the dipole approximation for N2O at different photon energies, coincided with pre-docu
We prove a uniqueness result for autonomous divergence-free systems of ODE's in the plane and give an application to the study of water flows with vorticity.
As digital photography is being increasingly used in clinical medicine, we devised a software program for 'on screen' image analysis, which allows distance, angle, and area to be measured. In this study, 30 photos were evaluated by 10 observers, so 3000 observations were used to test the reproducibility of the measurements. The results showed excellent reproducibility within observer, between obse
In this paper we present algorithms to compute finite state automata which, given any rational language, recognize the languages of normal words and n-chains. We also show how these automata can be used to compute the Hilbert series and Poincaré series for any algebra with a rational set of leading words of its minimal Gröbner basis.
In Lake Washington, juvenile sockeye salmon (Oncorhynchus nerka) strongly prefer Daphnia over other prey, switching uniformly to Daphnia when the threshold abundance of 0.4 Daphnia L-1 is achieved. Using long-term Lake Washington data (1978-2001) and fry trap data (1992-2001) from a major tributary, we examined the following: (i) factors that predict Daphnia pulicaria and Daphnia thorata increase

This paper presents solutions to the modelling of frequency data of species labels, but the data is incomplete in the sense that some rarely-occurring species labels give zero observed frequency. The data can be modelled by a monotone probability function with parameters to be estimated, and yet, due to the order constraints and the incomplete data, using conventional parameter estimation methods
With diversified requirements and varying manufacturing environments, the optimal production planning for a steelmill becomes more flexible and complicated. The flexibility provides operators with auxiliary requirements through an implementable integrated production planning. In this paper, a mixed-integer nonlinear programming (MINLP) model is proposed for the optimal planning that incorporates v
n this paper, we study the inventory system of an online retailer with compound Poisson demand. The retailer normally replenishes its inventory according to a continuous review (nQ, R) policy with a constant lead time. Usually demands that cannot be satisfied immediately are backordered. We also assume that the customers will accept a reasonable waiting time after they have placed their orders bec
Survival for patients on dialysis is poor. Earlier reports have indicated that home-hemodialysis is associated with improved survival but most of the studies are old and report only short-time survival. The characteristics of patient populations are often incompletely described. In this study, we report long-term survival for patients starting home-hemodialysis as first treatment and estimate the
