Hearing loss and a supportive tactile signal in a navigation system: Effects on driving behavior and eye movements

An on-road study was conducted to evaluate a complementary tactile navigation signal on driving behaviour and eye movements for drivers with hearing loss (HL) compared to drivers with normal hearing (NH). 32 participants (16 HL and 16 NH) performed two preprogrammed navigation tasks. In one, participants received only visual information, while the other also included a vibration in the seat to gui

Quantitative serial imaging of an I-124 anti-CEA monoclonal antibody in tumor-bearing mice

Objective: The 4.2-day half-life I-124 favors its use for positron emission tomography (PET) of monoclonal antibodies (mAbs). However, high positron energy and beta(+)-associated cascade gamma rays pose image resolution and background noise problems for I-124. This study evaluated quantitative PET of an I-124 mAb in tumor-bearing mice. Methods: An R4 microPET (TM) (Siemens/CTIMI, Knoxville, TN) wa

Multi-generational long-distance migration of insects: studying the painted lady butterfly in the Western Palaearctic

Long-range, seasonal migration is a widespread phenomenon among insects, allowing them to track and exploit abundant but ephemeral resources over vast geographical areas. However, the basic patterns of how species shift across multiple locations and seasons are unknown in most cases, even though migrant species comprise an important component of the temperate-zone biota. The painted lady butterfly

Implementation of Formalin-Fixed, Paraffin-Embedded Cell Line Pellets as High-Quality Process Controls in Quality Assessment Programs for KRAS Mutation Analysis

In recent years, the mutational status of the KRAS oncogene has become incorporated into standard medical care as a predictive marker for therapeutic decisions related to patients with metastasized colorectal cancer. This is necessary, because these patients benefit from epidermal growth factor receptor (EGFR)-targeted therapy with increased progression-free survival only if the tumor does not car

Causality, Magnitude and Impact Mitigation of Rework in Uganda

Popular Abstract in English Research has shown the Ugandan construction industry to be, primarily, an informal sector dominated by unskilled labour contracted mainly on minor building works such as alterations and renovations. Within such a context, the industry has also received negative publicity due to increasing quality failures on sites – commonly referred to as shoddy work.

Atomic structure of Yb/Si(100)(2X6): Interrelation between the silicon dimer arrangement and Si 2p photoemission line shape

Combining photoelectron spectroscopy and density-functional theory calculations, we have studied the atomic geometry of Yb/Si(100)(2 X 6) reconstruction and the mechanisms responsible for its stabilization as well as the influence of this reconstruction on Si 2p core-level photoemission. The analysis of measured and calculated surface core-level shifts supports the recently proposed model of the Y

Sensory mechanisms in the human upper airway - Role of TRP ion channels

The nasal mucosa is richly innervated with sensory nerves having the ability to detect changes in the environment and mediate symptoms such as secretion and itch. Some TRP ion channels such as TRPV1 and TRPA1 are abundantly expressed in sensory nerves and respond to a wide variety of stimuli, including irritants, inflammatory mediators and temperatures. Another interesting TRP ion channel is TRPV4

A New Route toward Semiconductor Nanospintronics: Highly Mn-Doped GaAs Nanowires Realized by Ion-Implantation under Dynamic Annealing Conditions

We report on highly Mn-doped GaAs nanowires (NWs) of high crystalline quality fabricated by ion beam implantation, a technique that allows doping concentrations beyond the equilibrium solubility limit. We studied two approaches for the preparation of Mn-doped GaAs NWs: First, ion implantation at room temperature with subsequent annealing resulted in polycrystalline NWs and phase segregation of MnA

Topological model and analysis of the P2P BitTorrent protocol

In this paper, we propose a directed and weighted graph model for describing P2P networks using BitTorrent protocol. Then, we analysis the topological properties of the model based on complex networks theory. We find that the node strength follows a power-law distribution and that there exists a positive correlation between flow betweenness and out-strength. We also include some other findings abo

Sender- and receiver-specific blockmodels

We propose a sender-specific blockmodel for network data which utilizes both the group membership and the identities of the vertices. This is accomplished by introducing the edge probabilities $(\theta_{i, v})$ for $1\le i\le c, 1\le v\le n$, where $i$ specifies the group membership of a sending vertex and $v$ specifies the identity of the receiving vertex. In addition, group membership is conside

Association between 25-hydroxyvitamin D levels and cognitive performance in middle-aged and older European men

Background: Although there is evidence that vitamin D inadequacy may be linked to adverse cognitive outcomes, results from studies on this topic have been inconsistent. The aim of this trial was to examine the association between 25-hydroxyvitamin D (25(OH) D) levels and cognitive performance in middle-aged and older European men. Methods: This population-based cross-sectional study included 3,369

Kristina Fjelkestam, Det sublimas politik: emancipatorisk estetik i 1800-talets konstnärsromaner

The review of Kristina Fjelkestam’s Det sublimas politik: emancipatorisk estetik i 1800-talets konstnärsromaner [Sublime politics: emancipatory aesthetics in nineteenth-century Künstlerromane] focuses on how the author makes use of the sublime as a means to connect three women writers use of the Künstlerromane in their political, emancipatory projects. On the other hand, the review also deals with

Electromagnetic scattering by a bounded obstacle in a parallel plate waveguide

This paper concerns scattering of an electromagnetic wave by a bounded object located inside a parallel plate waveguide. The exciting field in the waveguide is either an arbitrary source located at a finite distance from the obstacle or a plane wave generated in the far zone. In the latter case, the generating field corresponds to the lowest propagating mode (TEM) in the waveguide. The analytic tr

Search for the Standard Model Higgs boson in the decay channel H -> ZZ(()*()) -> 4l with the ATLAS detector

A search for the Standard Model Higgs boson in the decay channel H -> ZZ(()*()) l(+)l(-)l'l'(-), where l = e, mu, is presented. Proton-proton collision data at root s = 7 TeV recorded with the ATLAS detector and corresponding to an average integrated luminosity of 2.1 fb(-1) are compared to the Standard Model expectations. Upper limits on the production cross section of a Standard Model Higgs boso

Genetic diversity of avian blood parasites in SE Europe: Cytochrome b lineages of the genera Plasmodium and Haemoproteus (Haemosporida) from Bulgaria

We used a nested PCR protocol to examine the genetic diversity of cytochrome b (cyt b) lineages from blood parasites of the genera Plasmodium and Haemoproteus in birds in Bulgaria. In total, 460 birds of 43 species and 14 families (mostly passerines) were examined for the presence of infections. Of them, 267 were recognised as infected with haemosporidian parasites. Mixed infections were recorded

Leetocracy : Political participation, social network sites and inequality

Popular Abstract in Swedish Kan sociala nätverkssajter eller sociala medier som Facebook och Twitter göra att det politiska deltagandet i samhället blir med jämlikt - både med avseende på vilka personer som deltar och med avseende på hur själva engagemanget organiseras? Denna avhandling innehåller sex artiklar som studerar detta med tyngdpunkt på politiskt deltagande i Sverige, samt en introduktioThis dissertation is about whether social network sites have the potential to bring about more equal participation. It deals with a phenomenon that has changed the underlying infrastructure of how millions of people communicate. It studies the way the use of social network sites affects communication within existing political organisations in addition to networked campaigns. And it goes beyond dig
