Assume that we have two perspective images with known intrinsic parameters except for an unknown common focal length. It is a minimally constrained problem to find the relative orientation between the two images given six corresponding points. To this problem which to the best of our knowledge was unsolved we present an efficient solver. Through numerical experiments we demonstrate that the algori
The water vapor interface of aqueous solutions of succinic acid, where pH values and bulk concentrations were varied, has been studied using surface sensitive X-ray photoelectron spectroscopy (XPS) and molecular dynamics (MD) simulations. It was found that succinic acid has a considerably higher propensity to reside in the aqueous surface region than its deprotonated form, which is effectively dep
The International Commission on Stratigraphy and the IUGS Executive Committee have recently approved a Global Standard Stratotype-section and Point (GSSP) defining the base of the second stage of the Furongian Series, Cambrian System. This stage is named the Jiangshanian Stage, after Jiangshan City, western Zhejiang Province, China, where the GSSP is located. The GSSP is exposed in a natural outcr
An updated detailed kinetic mechanism for ozone combustion is developed. The contemporary choice of the reaction rate constants is presented with emphasis on their uncertainties. Model predictions are compared with available experimental data for ozone decomposition flames and with the Moscow State University (MSU) mechanism used elsewhere in the literature. These two models show similar performan
Inelastic neutron scattering was used to study the effect of 5 and 40 mol% cholesterol on the lateral nanoscale dynamics of phospholipid membranes. By measuring the excitation spectrum at several lateral q (||) values (up to q (||) = 3 (-1)), complete dispersion curves were determined of gel, fluid and liquid-ordered phase bilayers. The inclusion of cholesterol had a distinct effect on the collect
Experiments with birch bark samples have been carried to enable a distinction between extraction and degradation effects during pressurised hot water extraction. Two samples, E80 and El 80, contained birch bark extracts obtained after extraction at 80 and 180 degrees C for up to 45 min, respectively. Two other samples, P80 and P180, were only extracted for 5 min at the two temperatures and were th
Pyrimidine bases are the central precursors for RNA and DNA, and their intracellular pools are determined by de novo, salvage and catabolic pathways. In eukaryotes, degradation of uracil has been believed to proceed only via the reduction to dihydrouracil. Using a yeast model, Saccharomyces kluyveri, we show that during degradation, uracil is not reduced to dihydrouracil. Six loci, named URC1-6 (f
The Ga(x)In(1-x)Sb ternary system has many interesting material properties, such as high carrier mobilities and a tunable range of bandgaps in the infrared. Here we present the first report on the growth and compositional control of Ga(x)In(1-x)Sb material grown in the form of nanowires from Au seeded nanoparticles by metalorganic vapor phase epitaxy. The composition of the grown Ga(x)In(1-x)Sb na
Elements of family dynamics have been shown to be related to onset, course, as well as prognosis of anorexia nervosa and bulimia nervosa. The goal was to explore the experience of family relations in a group of patients with eating disorders using a projective family test. The Patient group (anorexia=21, bulimia=16), as well as a healthy Control group, were given a projective family test, the Eati
Popular Abstract in Swedish Omkring 16% av alla cancerfall i världen beräknas vara orsakade av infektioner och omkring 5% av dessa orsakas av humant papillomvirus (HPV). HPV har etablerats som orsak till livmoderhalscancer och kondylom (könsvårtor). HPV-typer som förekommer på hud har förknippats med icke-melanom hudcancer såsom skivepitelcancer (SCC) men också ofarliga hudhudförändringar som aktiAround 5% of all cancer cases worldwide are caused by human papillomavirus (HPV) which has been established as the cause of cervical cancer and genital warts (condylomas). Cutaneous HPV types have been weakly associated with non-melanoma skin lesions such as squamous cell carcinoma (SCC) and actinic keratosis (AK). We have analyzed skin and genital lesions for presence of HPV-DNA in order to searc
This article reports on the successful stabilization of the carrier-envelope phase of a 1-kHz laser system that includes a large grating stretcher, a regenerative amplifier, a multipass amplifier and a grating compressor. Phase stability for pulse energies up to 6 mJ is demonstrated using electronic feedback to the oscillator locking electronics as well as feedback via an acousto-optic programmabl
We analyze a similar to 70 ks Chandra Advanced CCD Imaging Spectrometer exposure of the globular cluster omega Cen (NGC 5139). The similar to 17' x 17' field of view fully encompasses three core radii and almost twice the half-mass radius. We detect 180 sources to a limiting flux of similar to 4.3 x 10(-16) erg cm(-2) s(-1) (L-x = 1.2 x 10(30) erg s(-1) at 4.9 kpc). After accounting for the number
This article analyzes the development of the practice for receiving non-Orthodox in Greek Orthodox canon law. The main argument is that the development of this canonical institution was influenced by a pneumatological realist ecclesiology. This historical study of the development of a canonical institution will shed light on how Greek Orthodox canon law has functioned in practice.
Soil phosphorus (P) composition changes with ecosystem development, leading to changes in P bioavailability and ecosystem properties. Little is known, however, about how soil P transformations proceed with ecosystem development in boreal regions. We used 1-dimensional P-31 and 2-dimensional H-1, P-31 correlation nuclear magnetic resonance (NMR) spectroscopy to characterise soil organic P transform
Life expectancy is increasing in most developed countries, in part due to improved socioeconomic conditions and in part to advances in healthcare. It is widely acknowledged that the promotion of healthy ageing by delaying, minimizing or preventing disabilities or diseases is one of the most important public health objectives in this century. In contrast to the menopausal transition in females, we
Background. Although short-term graft survival has improved substantially in renal transplant recipients, long-term graft survival has not improved over the last decades. The lack of knowledge of specific causes and risk factors has hampered improvements in long-term allograft survival. There is an uncertainty if inflammation is associated with late graft loss. Methods. We examined, in a large pro
Pancreatic beta-cells secrete insulin by Ca2+-dependent exocytosis of secretory granules. beta-cell exocytosis involves SNARE (soluble NSF-attachment protein receptor) proteins similar to those controlling neurotransmitter release and depends on the close association of L-type Ca2+ channels and granules. In most cases, the secretory granules fuse individually but there is ultrastructural and bioph
