We have developed and characterized a hard x-ray accumulating streak camera that achieves subpicosecond time resolution by using single-photon counting. A high repetition rate of 2 kHz was achieved by use of a readout camera with built-in image processing capabilities. The effects of sweep jitter were removed by using a UV timing reference. The use of single-photon counting allows the camera to re
Background: Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor (GHSR), has two major functions: the stimulation of the growth hormone production and the stimulation of food intake. Accumulating evidence also indicates a role of ghrelin in cancer development. Methods: We conducted a case-control study to examine the association of common genetic variants in the genes coding
The most commonly used technology currently used for autoradiography is storage phosphor screens, which has many benefits such as a large field of view but lacks particle-counting detection of the time and energy of each detected radionuclide decay. A number of alternative designs, using either solid state or scintillator detectors, have been developed to address these issues. The aim of this stud
Fermented milk is commonly eaten during breakfast or as a snack between meals either in one-portion cups or from a bowl with a spoon. Approximately 5-10% of the fermented milk remains in the packages upon pouring, which during the last years, has received attention in public media as newspapers and television. This is a problem, not only from an economical point of view, but also from an ecologica
In order to explore verbal-nonverbal integration, we investigated the influence of cognitive and linguistic ability on gaze behavior during spoken language conversation between children with mild-to-moderate hearing impairment (HI) and normal-hearing (NH) peers. Ten HI-NH and 10 NH-NH dyads performed a referential communication task requiring description of faces. During task performance, eye move
P>Background: Studies of the nasal lavage fluid proteome have previously identified proteins differently expressed in patients with symptomatic allergic rhinitis, e.g. S100A7, prolactin-inducible protein (PIP), wingless-type MMTV integration site family, member 2B (WNT2B), Charcot-Leyden crystal protein (CLC) and palate lung nasal epithelial clone (PLUNC). The aim of the present study was to inves
Current sampling of genomic sequence data from eukaryotes is relatively poor, biased, and inadequate to address important questions about their biology, evolution, and ecology; this Community Page describes a resource of 700 transcriptomes from marine microbial eukaryotes to help understand their role in the world's oceans.
I religionernas värld har man alltid varit medveten om vilken betydelse ljud och tystnad har för vårt välbefinnande. Ibland framhävs tystnaden; i andra fall kan det röra sig om det monotona ljude av exempelvis en upprepad bön. Sådana övningar blir föremål för en psykologisk kommentar.
I denna artikel tar jag upp ett berättargrepp, den narrativa syllepsen, som inte fått någon större uppmärksamhet i litteraturteorin hittills. Den narrativa syllepsen definierades först av den franske litteraturteoretikern Gérard Genette år 1972 som ett berättargrepp där olika temporaliteter smälter samman. Begreppet har dock inte använts i någon större utsträckning därefter, vilket jag anser vara In this article I discuss a narrative device, the narrative syllepsis, which has not received much attention in literary theory until now. The narrative syllepsis was first defined by French literary theorist Gérard Genette as a narrative device where different temporalities merge. The concept has however not been used att a larger scale after Genette, something I find surprising taking into consi
This article aims to explore critically the role of an action research team in the social construction of interorganizational collaboration aimed at transgressing organizational and professional boundaries. We argue that the new relationships, actor conceptions and in some cases forms of work organization arising from the change process have been socially constructed through the discursive interve
A search for events with large missing transverse momentum, jets, and at least two tau leptons has been performed using 2 fb(-1) of proton-proton collision data at root s = 7 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectation is observed and a 95% CL upper limit on the visible cross section for new phenomena is set, where th
This study investigates several commercial selective catalytic reduction (SCR) catalysts (A–E) for application in a high-temperature (approximately 525 °C) and high-concentration (5000 ppm NO) system in combination with CO2 capture. The suggested process for removing high concentrations of NOx seems plausible and autothermal operation is possible for very high NO concentrations. A key property of
Recent developments in extremum seeking theory have established a general framework for the methodology, although the specific implementations, particularly in the context of multi-agent systems, have not been demonstrated. In this work, a group of sensor-enabled vehicles is used in the context of the extremum seeking problem using both local and global optimisation algorithms to locate the extrem
Background: Earlier studies have shown an association between secondhand tobacco smoke and allergy development in children. Furthermore, there is an increased risk of developing an allergy if the parents have an allergy. However, there are only few studies investigating the potential synergistic effect of secondhand tobacco smoke and allergic heredity on the development of an allergy. Methods: The
The dinuclear title compound, [FePtCl2(C17H14P)(C23H23NO3P)]x1.25CH2Cl2, has a slightly distorted cis-PtCl2P2 square-planar geometry around the Pt atom, and the ferrocenylphosphine ligands are staggered at an angle of 29.4 (2) deg. about Pt. In the crystal structure, the complex forms centrosymmetric dimers via two strong intermolecular O—H-O bonds resulting in R22(8) rings. A weak intramolecular
This work studies the design of linear precoder codebooks for N-r x N-t MIMO channels with MMSE detection at the receiver. A natural split of precoder-design is unitary precoding and non-unitary precoding. Unitary precoding is only performing rotation of the data in a way beneficial for the channel. Non-unitary precoding additionally also uses power-loading to further improve the performance. Some
