On the existence and conditional energetic stability of solitary water waves with weak surface tension

An existence and stability theory for solitary water waves with weak surface tension has recently been given by Buffoni (2005, 2009) [2,3]. The theory, which is variational in nature, relies upon the assumption that the infimum of the variational functional is strictly subhomogeneous with respect to a small parameter. In this Note we rigorously establish the relevant strict-subhomogeneity property

Rate-Adaptive Tasks: Model, Analysis, and Design Issues

In automotive systems, some of the engine control tasks are triggered by specific crankshaft rotation angles and are designed to adapt their functionality based on the angular velocity of the engine. This paper proposes a new task model for specifying such a type of real-time activities and presents an approach for analyzing the system feasibility under dynamic scheduling for different scenarios.

The influence of detector effects on TPC performance

TPC stand alone simulations based on different energy loss models are compared to previously reported measurements with an ALICE TPC prototype. The performance obtained from simulations is shown to depend significantly on all the included detector effects stressing that energy loss model calculations alone are inadequate for describing the performance. When all effects are included, a good quantit

Nonperturbative modeling of fifth-order coherent multidimensional spectroscopy in light harvesting antennas

Recent advances in coherent multidimensional spectroscopy have boosted interest in exciton coherences in light harvesting complexes. We present nonperturbative calculations of two-dimensional (2D) electronic spectroscopy from a fifth-order phase-matching direction. The calculations show clear patterns that correspond to the electronic structure of one- and two-exciton manifolds of a Fenna-Matthews

New Flexible Toolbox for Nanomechanical Measurements with Extreme Precision and at Very High Frequencies.

We show that the principally two-dimensional (2D) scanning tunneling microscope (STM) can be used for imaging of 1D micrometer high free-standing nanowires. We can then determine nanowire megahertz resonance frequencies, image their top-view 2D resonance shapes, and investigate axial stress on the nanoscale. Importantly, we demonstrate the extreme sensitivity of electron tunneling even at very hig

The composite structure of mixed tau-(Ag, Cu)(x)V2O5 bronzes Evidence for T dependant guest-species ordering and mobility

The complex structural behavior of tau-[AgCu](similar to 0.92)V4O10 has been elucidated by single crystal X-ray diffraction and thermal analysis. The tau-phase region is apparently composed of several distinct phases and this study identifies at least three: tau(1rt) tau(2rt) and tau(1t), tau(1rt) and tau(2rt) have slightly different compositions and crystal habits. Both phases transform to Tit at

Spinal Cord FAAH in Normal Micturition Control and Bladder Overactivity in Awake Rats

Purpose: We assessed whether spinal inhibition of the cannabinoid degrading enzyme FAAH would have urodynamic effects in normal rats and rats with bladder overactivity induced by partial urethral obstruction or prostaglandin E2. We also determined the expression of FAAH, and the cannabinoid receptors CB1 and CB2 in the sacral spinal cord. Materials and Methods: We used 44 rats for functional (cyst

Low-temperature spectroscopy of bacteriochlorophyll c aggregates

Chlorosomes from green photosynthetic bacteria belong to the most effective light-harvesting antennas found in nature. Quinones incorporated in bacterichlorophyll (BChl) c aggregates inside chlorosomes play an important redox-dependent photo-protection role against oxidative damage of bacterial reaction centers. Artificial BChl c aggregates with and without quinones were prepared. We applied hole-

The Douglas-Kroll-Hess electron density at an atomic nucleus

The picture-change error on Douglas-Kroll-Hess (DKH) electron densities at atomic nuclei is analyzed in detail to high orders. Our results demonstrate that high-order DKH transformations of especially the property operator are needed to obtain converged results. However, if the convergence properties are discussed in terms of a relative error a fast convergence of the picture-change corrected DKH

I’m a Believer – But I’ll Be Damned if I’m Religious : Belief and Religion in the Greater Copenhagen Area : A Focus Group Study

This book is a contribution to the discussion about religion in contemporary Western society, characterized by the privatization of religion. The concept religion is not easily operational and does not carry meaning or implications that remain valid or consistent over time. It must be re-substantiated in order to remain descriptive and operational. This book’s ambition is to explore a means of re-

A fast and scalable kymograph alignment algorithm for nanochannel-based optical DNA mappings.

Optical mapping by direct visualization of individual DNA molecules, stretched in nanochannels with sequence-specific fluorescent labeling, represents a promising tool for disease diagnostics and genomics. An important challenge for this technique is thermal motion of the DNA as it undergoes imaging; this blurs fluorescent patterns along the DNA and results in information loss. Correcting for this

Advances in Magnetic Resonance Imaging: How They Are Changing the Management of Prostate Cancer

Context: Although magnetic resonance imaging (MRI) is emerging as the most commonly used imaging modality for prostate cancer (PCa) detection, treatment planning, and follow-up, its acceptance has not been uniform. Recently, great interest has been shown in multiparametric MRI, which combines anatomic T2-weighted (T2W) imaging with MR spectroscopic imaging (MRSI), dynamic contrast-enhanced MRI (DC

Energy Transitions, Economic Growth and Structural Change: Portugal in a Long-run Comparative Perspective

This book analyses, in an international comparative context, Portugal´s energy transition from organic sources to fossil fuels in the period 1856-2006. It investigates the role that energy played in the industrialization of the country and how the relationship between energy and economic growth changed with the transition from an industrial to a service society. A unique dataset of energy quantiti

Detectors for the European Spallation Source

The European Spallation Source (ESS) in Lund, Sweden will become the world's leading neutron source for the study of materials by 2025. First neutrons will be produced in 2019. It will be a long pulse source, with an average beam power of 5 MW delivered to the target station. The pulse length will be 2.86 ms and the repetition rate 14 Hz. The ESS is presently in a design update phase, which ends i

Slips and falls in a cold climate: underfoot surface, footwear design and preference of preventive measures

Slips and falls and associated outdoor injuries are prevalent in cold climates. The objectives of this field investigation were to describe the consequences of slips and falls on ice and snow and the associated injuries, to assess the risks of various icy and snowy surfaces, to identify design needs of footwear, and to ascertain preventive measure preferences of outdoor workers.
