Non-Linear Portmanteau Tests

We derive Portmanteau tests for a large class of non-linear time series models. This is done by replacing the linear measure of dependence (correlation) with a more general concept. Asymptotic distributions for the test statistics are derived. The methodology is computationally inexpensive, yet more flexible than most similar tests. The tests are evaluated on two different sets of simulated data.

Magmatism during Gondwana break-up: new geochronological data from Westland, New Zealand

Newly determined Late Cretaceous Ar-40/Ar-39 ages on megacrystic kaersutite from four lamprophyre dikes, and a U-Pb zircon age on a trachyte, from central and north Westland (New Zealand) are presented. These ages suggest that the intrusion of mafic dikes (88-86 and 69 Ma) was not necessarily restricted to the previously established narrow age range of 80-92 Ma. The younger lamprophyre and trachyt

Late Quaternary glaciation history of Isla de los Estados, southeasternmost South America

Isla de los Estados is a mountainous island southeast of Tierra del Fuego, in southernmost South America. Its central and eastern parts have an alpine topography, transected by U-shaped valleys, small, partly over-deepened fjords, and a multitude of abandoned cirques, all associated with extensive former local glaciations. Traces of glacial erosion generally reach 400-450 m a.s.l., and above that

The Geological Society of America Geologic Time Scale

The Geological Society of America has sponsored versions of the geologic time scale since 1983. Over the past 30 years, the Geological Society of America Geologic Time Scale has undergone substantial modifications, commensurate with major advances in our understanding of chronostratigraphy, geochronology, astrochronology, chemostratigraphy, and the geomagnetic polarity time scale. Today, many part

Robot-assisted laparoscopy for benign uterine disease. Feasibility, outcome and hospital cost.

The introduction of the laparoscope was a milestone within gynecologic surgery. Despite evidence of better perioperative outcome compared to laparotomy, laparoscopy is mostly performed for less advanced surgical procedures and the uptake of laparoscopic hysterectomy has been slow. An effort to preserve the clinical benefits of laparoscopic surgery and facilitate the performance of more advanced su

Photoelectron angular distributions for the two-photon ionization of helium by ultrashort extreme ultraviolet free-electron laser pulses

The two-photon ionization of helium atoms by ultrashort extreme-ultraviolet free-electron laser pulses, produced by the SPring-8 Compact SASE Source test accelerator, was investigated at photon energies of 20.3, 21.3, 23.0 and 24.3 eV. The angular distribution of photoelectrons generated by two-photon ionization is obtained using a velocity map imaging spectrometer. The phase-shift differences and

The aim of this thesis was first to investigate the lifetime prevalence of sexual abuse of varying severity and characteristics as well as the associations between sexual abuse, gender, socio-demographic character

Low toxicity regimens in renal transplantation: a country subset analysis of the Symphony study

P>Regional transplant practices may affect clinical outcomes within multinational studies. This study evaluated whether the overall results from the Symphony study can be generalized to the participating countries. De novo adult renal transplant recipients (n = 1645) were randomized to receive standard-dose cyclosporine, or daclizumab induction plus low-dose cyclosporine, low-dose tacrolimus, or l

Analysis of borehole geophysical data from the Mora area of the Siljan Ring impact structure, central Sweden

The Siljan impact structure is the largest known impact structure in Europe, the result of a Late Devonian meteorite impact (380.9 +/- 4.6 Ma). It is outlined mainly by a ring of lakes and Palaeozoic sedimentary rocks of Ordovician to Devonian age. The Palaeozoic successions are generally poorly exposed, but often well preserved with clear stratigraphy. At some locations they are strongly tectonis

Emerging pharmacotherapies for Parkinson's Disease: Experimental studies in the rat

Parkinson´s disease (PD) is a neurodegenerative disorder characterized by the typical motor symptoms, akinesia/bradykinesia, rigidity and resting tremor. These symptoms are caused by a deficiency of dopamine (DA) in the brain, which depends on degeneration of DA neurons in the substantia nigra. The most effective treatment for PD is the DA precursor, L-DOPA. Unfortunately, within a few years, L-DO

antibody microarray analysis of directly labelled proteomes

In recent years, the antibody microarray technology has made significant progress, going from proof-of-concept designs to established high-performing technology platforms capable of targeting non-fractionated complex proteomes. In these cross-disciplinary efforts, a particular focus has lately been placed on two key technological issues: the sample and data handling. To this end, robust protocols

Aberrant DNA methylation of cancer-associated genes in gastric cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC-EURGAST)

Epigenetic events have emerged as key mechanisms in the regulation of critical biological processes and in the development of a wide variety of human malignancies, including gastric cancer (GC), however precise gene targets of aberrant DNA methylation in GC remain largely unknown. Here, we have combined pyrosequencing-based quantitative analysis of DNA methylation in 98 GC cases and 64 controls ne

Can histology solve the riddle of non-functioning electrodes; factors influencing the biocompatibillity of brain machine interfaces.

Neural interfaces hold great promise to become invaluable clinical and diagnostic tools in the near future. However, the biocompatibility and the long-term stability of the implanted interfaces are far from optimized. There are several factors that need to be addressed and standardized when improving the long-term success of an implanted electrode. We have chosen to focus on three key factors when

A quarter of a century of job transitions in Germany

By examining trends in intra-organizational and inter-organizational job transition probabilities among professional and managerial employees in Germany, we test the applicability of mainstream career theory to a specific context and challenge its implied change assumption. Drawing on data from the German Socio-Economic Panel (GSOEP), we apply linear probability models to show the influence of tim

Measurement of D*(+/-) meson production and determination of F-2(c(c)over-bar) at low Q(2) in deep-inelastic scattering at HERA

Inclusive production of D* mesons in deep-inelastic ep scattering at HERA is studied in the range 5 < Q(2) < 100 GeV2 of the photon virtuality and 0.02 < y < 0.7 of the inelasticity of the scattering process. The observed phase space for the D* meson is (pT) (D*) > 1.25 GeV and |eta( D*)| < 1.8. The data sample corresponds to an integrated luminosity of 348 pb(-1) collected with the H1 detector. S

Novel lactic acid bacteria inhibiting Paenibacillus larvae in honey bee larvae

We evaluated the antagonistic effects of newly identified lactic acid bacteria (LAB) in the genera Lactobacillus and Bifidobacterium, originating from the honey stomach, on the honey bee pathogen, Paenibacillus larvae. We used inhibition assays on agar plates and honey bee larval bioassays to investigate the effects of honey bee LAB on P. larvae growth in vitro and on AFB infection in vivo. The in

Energy-driven asymmetric partitioning of a semiflexible polymer between interconnected cavities

The distribution of a semiflexible chain in the volume of two interconnected spherical cavities of equal size has been investigated by using Monte Carlo simulations. The chain possessed an extension exceeding that of the cavity, leading to large probabilities of translocated states despite the entropic penalty of passing the narrow passage. Furthermore, an asymmetric state with unequal subchain le
