A pseudo coherence estimate using multitapers is presented. The estimate has better localization for sinusoids and is shown to have lower variance for disturbances compared to the usual coherence estimator. This makes it superior in terms of finding coherent frequencies between two sinusoidal signals; even when observed in low SNR. Different sets of multitapers are investigated and the weights of
Is the real problem in finding the relative orientation of two viewpoints the correspondence problem? We argue that this is only one difficulty. Even with known correspondences, popular methods like the eight point algorithm and minimal solvers may break down due to planar scenes or small relative motions. In this paper, we derive a simple, brute-force algorithm which is both robust to outliers an
Fish, which are generally visual foragers, experiences reduced reaction distance in visually degraded environments, which has consequences for encounter rates with prey. Small prey is detected at shorter distances than larger prey, and piscivores are therefore predicted to be more strongly affected by visual degradation. In experiments, roach (Rutilus rutilus) were fed two plankton prey types and
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
This paper employs a semiparametric procedure to estimate the diffusion process of short-term interest rates. The Monte Carlo study shows that the semiparametric approach produces more accurate volatility estimates than models that accommodate asymmetry, levels e¤ect and serial dependence in the conditional variance. Moreover, the semiparametric approach yields robust volatility estimates even if
Rationale: Atherosclerotic plaques that give rise to acute clinical symptoms are typically characterized by degradation of the connective tissue and plaque rupture. Experimental studies have shown that mechanisms to repair vulnerable lesions exist, but the rate of remodeling of human plaque tissue has not been studied. Objective: In the present study, we determined the biological age of different
Speech is already in itself a writing. Any concept that is to name, to stay for the abstract or concrete reality is made up of a mental trace. There is always a sleepy-waiting yet ever present trace at the origin of the representation and the naming of any ontological phenomenon. The trace is itself The apriori ontology – and this is how writing is pre-eminent to the later formal verbalization of
The clinical performance of two nucleic acid amplification assays targeting the cryptic plasmid and two assays targeting rRNA molecules in Chlamydia trachomatis was examined. First-catch urine samples from Malmoe, Sweden, were tested for C. trachomatis with the Abbott real-time PCR assay m2000 and an in-house PCR for the new variant strain of C. trachomatis with a deletion in the cryptic plasmid.
While contacts between Scandinavia and Kievan Rus’ in recent history have been limited, and Scandinavian, and Scandinavian-Canadian attitudes to Ukrainians were long characterized by an aggressive hostility and racist stereotypes. The image of the “Galician” merged with stereotypes of Russians, which have a long tradition in Scandinavia and Germany. “Galicians” became synonymous with backwardness,
Popular Abstract in Swedish Idag tar de flesta för givet att man när och var som helst kan komma åt sin e-post, ladda upp bilder till Facebook eller söka kunskap på Wikipedia från sin mobiltelefon eller dator. Den trådlösa teknologi som gjort detta möjligt har utvecklats oerhört det senaste årtiondet, men behöver utvecklas ännu mer för att möta det ökande behovet av trådlös kommunikation. I dennaThe traffic in wireless networks has been showing an exponential growth over the last decade. In order to meet the demand, and support a continuation of this growth, the scarce radio resources need to be efficiently used. The use of multiple antenna (MIMO) systems and iterative (turbo) receivers has significantly improved the realizable system performance. Still, many challenges exist in the devel
I Lomma kommun gör man det, Universitetssjukhuset Mas (UMAS) likaså. Även Hässleholms sjukhusorganisation (Hässleholms sjukhus) gör det. Styr med mål. Det kan vi konstatera efter att precis ha avslutat en rapport som handlar om att framgångsrikt styra med mål. Rapporten har Föreningen Sveriges Kommunalekonomer finansierat. För er som vill läsa hela rapporten finns den att hämta på www.kef.se. Rapp

Popular Abstract in Swedish Standard-12-avlednings-EKG är fortfarande ett av de viktigaste och vanligaste redskapen för att diagnostisera hjärtsjukdom trots att ett flertal olika undersökningstekniker har utvecklats under åren. Vid standard-EKG används 10 elektroder, 6 på bröstkorgen och 4 distalt på armar och ben. Inom både industrin och akademin har många års arbete lagts ned på utveckling av deThe standard 12-lead electrocardiogram (ECG) remains one of the most important and most frequently used tools for diagnosing cardiac diseases, although several different examination modalities in cardio¬logy have been developed over the years. The standard ECG uses 10 electrodes placed on well-defined positions on the body, 6 on the torso and 4 distally on the limbs. Both industry and academia hav
