COSMO: CO-Simulation with MATLAB and OMNeT++ for indoor wireless networks

Simulations are widely used to design and evaluate new protocols and applications of indoor wireless networks. However, the available network simulation tools face the challenges of providing accurate indoor channel models, three-dimensional (3-D) models, model portability, and effective validation. In order to overcome these challenges, this paper presents a new CO-Simulation framework based on M

Structure of premixed ammonia plus air flames at atmospheric pressure: Laser diagnostics and kinetic modeling

The structure of premixed ammonia air flames, burning at atmospheric pressure under strain-stabilized conditions on a porous-plug burner, has been investigated using laser-diagnostic methods. Profiles of OH, NH, and NO were acquired by laser-induced fluorescence (LIF) and quantitative concentrations of OH and NO were retrieved using a concept for calibration versus absorption utilizing the LIF-sig

Agentic, communal, and spiritual traits are related to the semantic representation of written narratives of positive and negative life events

Background: We used a computational method to quantitatively investigate the relationship between personality and written narratives of life events. Agentic (i.e., self- directedness), communal (i.e., cooperativeness), and spiritual (self-transcendence) traits were of special interest because they represent individual differences in intentional val- ues and goals, in contrast to temperament traits

Direct and indirect spino-cerebellar pathways: shared ideas but different functions in motor control.

The impressive precision of mammalian limb movements relies on internal feedback pathways that convey information about ongoing motor output to cerebellar circuits. The spino-cerebellar tracts (SCT) in the cervical, thoracic and lumbar spinal cord have long been considered canonical neural substrates for the conveyance of internal feedback signals. Here we consider the distinct features of an indi

Physical activity in persons with late effects of polio

Physical activity is beneficial for the health of persons with disabilities but the levels of such activity are lower than for persons without disability. In addition the level of physical activity decreases with increasing age. For persons aging with a disability it may be a challenge to engage in physical activity, partly because of the disability and partly because of contextual barriers. One g

Extrapolation-Based References Improve Motion and Eddy-Current Correction of High B-Value DWI Data: Application in Parkinson's Disease Dementia.

Conventional motion and eddy-current correction, where each diffusion-weighted volume is registered to a non diffusion-weighted reference, suffers from poor accuracy for high b-value data. An alternative approach is to extrapolate reference volumes from low b-value data. We aim to compare the performance of conventional and extrapolation-based correction of diffusional kurtosis imaging (DKI) data,

Jet production in ep collisions at low Q(2) and determination of alpha(s)

The production of jets is studied in deep-inelastic e(+) p scattering at low negative four momentum transfer squared 5 < Q(2) < 100 GeV2 and at inelasticity 0.2 < y < 0.7 using data recorded by the H1 detector at HERA in the years 1999 and 2000, corresponding to an integrated luminosity of 43.5 pb(-1). Inclusive jet, 2-jet and 3-jet cross sections as well as the ratio of 3-jet to 2-jet cross secti

New shape minimum in Yb-160: Evidence for a triaxial, strongly deformed band

A high-spin rotational band was observed in the N=90 nucleus Yb-160 with moment of inertia and decay characteristics very similar to recently discovered sequences in Er-157,Er-158. These latter structures were discussed in terms of strongly deformed triaxial bands. Detailed cranked Nilsson-Strutinsky calculations were performed that predict that well-deformed triaxial structures are also expected

Performance of the AGATA Gamma-ray Spectrometer in the PreSPEC Set-up at GSI

In contemporary nuclear physics, the European Advanced GAmma Tracking Array (AGATA) represents a crucial detection system for cutting-edge nuclear structure studies. AGATA consists of highly segmented high-purity germanium crystals and uses the pulse-shape analysis technique to determine both the position and the energy of the γ-ray interaction points in the crystals. It is the tracking algorithms

Osmotic pressure: resisting or promoting DNA ejection from phage?

Recent in vitro experiments have shown that DNA ejection from bacteriophage can be partially stopped by surrounding osmotic pressure when ejected DNA is digested by DNase I in the course of ejection. In this work, we argue by a combination of experimental techniques (osmotic suppression without DNase I monitored by UV absorbance, pulse-field electrophoresis, and cryo-transmission electron microsco

Integration of HIV and cervical cancer screening perceptions of healthcare providers and policy makers in Uganda

Background: HIV-positive women have an increased risk of developing cervical cancer (CC) compared to the HIV-negative women. Despite this, HIV and CC screening programs in many developing countries have remained disintegrated. Therefore, the objective of the study was to explore perceptions of healthcare providers (HCP) and policy makers (PM) about integration of HIV and CC screening services in U

Lokala handlingsstrategier för skäliga levnadsvillkor - reflektioner utifrån Malmökommissionens studier om försörjningsstödet och barns fattigdom.

Artikeln fokuserar på lokala handlingsstrategier för att tillförsäkra skäliga levnadsvillkor och lyfter även fram reflektioner utifrån Malmökommissionens studier om försörjningsstödets funktion och räckvidd med fokus på familjers och barns ekonomiska utsatthet. Den ökade inkomstojämliketen tillsammans med en hög andel Malmöbors osäkra eller obefintliga ställning på den reglerade arbetsmarknaden oc

αTubulin 67C and Ncd Are Essential for Establishing a Cortical Microtubular Network and Formation of the Bicoid mRNA Gradient in Drosophila.

The Bicoid (Bcd) protein gradient in Drosophila serves as a paradigm for gradient formation in textbooks. To explain the generation of the gradient, the ARTS model, which is based on the observation of a bcd mRNA gradient, proposes that the bcd mRNA, localized at the anterior pole at fertilization, migrates along microtubules (MTs) at the cortex to the posterior to form a bcd mRNA gradient which i
