A method is suggested which allows truncation of the virtual space in Cholesky decomposition-based multiconfigurational perturbation theory (CD-CASPT2) calculations with systematic improvability of the results. The method is based on a modified version of the frozen natural orbital (FNO) approach used in coupled cluster theory. The idea is to exploit the near-linear dependence among the eigenvecto
Purpose and method: A review article concerning orthopaedic treatment and rehabilitation of displaced femoral neck fractures, focusing on evidence-based knowledge. Results: Properly performed randomized controlled studies comparing internal fixation and primary arthroplasty provides the best basis to decide which method should be used. During the last decade, several such studies have been publish
The intensities of infrared absorption due to the asymmetric stretching vibrations of interstitial oxygen atoms in Ge crystals enriched with O-16 and O-18 isotopes have been compared with oxygen concentrations determined by means of secondary ion mass spectrometry. For Ge samples with oxygen content less than 5 x 10(17) cm(-3), a good correlation has been found between the values of oxygen concent
Pyrene chromophores carrying different rigid rod spacer groups (ethynylene, ethynylene-phenylene-ethynylene, and ethynylene-bicyclo[2.2.2]octylene-ethynylene) and bound to TiO2 nanostructured materials via an isophthalic acid (Ipa) anchor group have been investigated using quantum chemical calculations in order to elucidate structural and electronic properties of dye-sensitized semiconductor struc
BACKGROUND: Cancer of the pancreas is a common disease, but the large majority of patients have tumours that are irresectable at the time of diagnosis. Moreover, patients whose tumours are clearly beyond surgical cure are best treated non-operatively, if possible, by relief of biliary obstruction and percutaneous biopsy to confirm the diagnosis and then consideration of oncological treatment, nota
Crucian carp (Carassius carassius) increases in body depth in response to chemical cues from piscivores and the deeper body constitutes a morphological defence against gape-limited piscivores. In the ®eld, deep-bodied individuals su€er a density-dependent cost when com- peting with shallow-bodied conspeci®cs. Here, we use hydrodynamic theory and swimming respirometry to investigate the proposed me
Models for materials with nonlinear electromagnetic response are examined. Three simple physical causes for nonlinear behavior are presented: electronic polarization, molecular direction and electrostriction. Some introductory results and approximations for nonlinear, dispersive media are given, such as the phase-matching criterion, Miller's rule, the Born approximation and the slowly varying ampl
Popular Abstract in Swedish Papillomvirus infekterar ett brett spektrum av ryggradsdjur, såsom människa, olika ap-arter, ko, älg, elefant, ren och bofink. Dessa virus kan ge så vitt skilda symptom som cancer och vårtor. De indelas efter vilken art de infekterar, och inom arterna efter skillnad i DNA-sekvens mellan olika isolat (typer). Hittills har 92 humana papillomvirus (HPV) typer beskrivits, oPapillomaviruses are a diverse, epitheliotropic group of viruses. Some genotypes are the main cause of anogenital cancer in humans; others can induce skin lesions. In order to investigate the occurrence of subclinical skin infections with human papillomavirus (HPV), a pair of degenerate primers (FAP59/64) was designed. Moist cotton-tipped swabs were used as a gentle method of sample collection. Di
Protein kinase C (PKC), a multi-gene family of enzymes, plays key roles in the pathways of signal transduction, growth control and tumorigenesis. Variations in the intracellular localization of the individual isoforms are thought to be an important mechanism for the isoform-specific regulation of enzyme activity and substrate specificity. To provide a dynamic method of analyzing the localization o
Economies in transition (EiTs) (e. g. Ukraine (UA), Belarus, Lithuania (LU), Moldova, etc.) face broad needs for energy security enhancement, energy diversification, revitalisation of agriculture and improvements in the state of the environment. Development of national bioenergy potentials can contribute to delivering solutions to these problems. However, EiTs face technical, political, financial,
Adsorption dynamics of various types of uncharged homopolymers onto solid surfaces in good solvent have been studied by using a coarse grained bead-spring model. Brownian dynamics simulation has been used to examine the adsorption process for polymers released near an adsorbing surface, and Monte Carlo simulations have been employed to explore equilibrium properties of adsorbed polymers. Two diff
In this study we investigate utterance-final intonation in two dialects of Kammu, one tonal and one non-tonal. While the general patterns of utterance-final intonation are similar between the dialects, we do find clear evidence that the lexical tones of the tonal dialect restrict the pitch range and the realization of focus. Speaker engagement can have a strong effect on the utterance-final accent
