Realistic network simulations are necessary to assess the performance of any communication system. In this paper, we describe an implementation of a channel model for vehicle-to-vehicle (V2V) communication in the OMNeT++/Plexe simulation environment. The model is based on previous extensive measurements in a V2V multilink highway scenario and cover line-of-sight (LOS) as well as obstructed LOS (OL

With 450,000 km2 Kobresia (syn. Carex) pygmaea dominated pastures in the eastern Tibetan highlands are the world's largest pastoral alpine ecosystem forming a durable turf cover at 3000–6000 m a.s.l. Kobresia's resilience and competitiveness is based on dwarf habit, predominantly below-ground allocation of photo assimilates, mixture of seed production and clonal growth, and high genetic diversity.

The performance of wireless communication systems is fundamentally determined by wireless communication channel properties. Wireless vehicular communication channels exhibit multipath propagation and non-stationary channel statistics. Methods and tools for the repeatable test of wireless communication systems and signal processing algorithms in such environments are urgently needed to enable the d

Scholarly textbooks often follow a logic where suitable empirical cases are selected to illustrate the theoretical and analytical points that we as scholars want to make. But what would happen if we would do the opposite: build a textbook on a novel written by a novelist for such purpose and let the theories explain the actions and emotions of fictional characters? In this article, we share and reScholarly textbooks often follow a logic where suitable empirical cases are selected to illustrate the theoretical and analytical points that we as scholars want to make.

The Xga blood group is differentially expressed on erythrocytes from men and women. The underlying gene, PBDX, was identified in 1994, but the molecular background for Xga expression remains undefined. This gene, now designated XG, partly resides in pseudoautosomal region 1 and encodes a protein of unknown function from the X chromosome. By comparing calculated Xga allele frequencies in different

We demonstrate a non-contact spatiotemporally resolved comprehensive method for gas flow velocity field measurement: Filamentary Anemometry using femtosecond Laser-extended Electric Discharge (FALED). A faint thin plasma channel was generated in ambient air by focusing an 800-nm laser beam of 45 fs, which was used to ignite a pulsed electric discharge between two electrodes separated over 10 mm. T

Bildandet av blodceller, hematopoesen, utgår från ett litet antal av de så kallade hematopoetiska stamceller som sitter i vår benmärg. Dessa celler har förmågan att ge upphov till alla mogna blodcellstyper av de tre hematopoetiska linjerna, samtidigt som de genom celldelning bibehåller sin egna mängd. Det har uppskattats att vi endast har några tusen hematopoetiska stamceller, men trots deras rela

Abstract in UndeterminedIn this paper we describe and reflect upon a novel methodology using attention cards to facilitate communication, concentration and creativity in a user requirement workshop with seniors. Previous research indicates that seniors tend to lose focus and start cross talking during workshops, which results in broad and shallow findings. However, our findings indicate that the u

Glucagon is the main counterregulatory hormone in the body. Still, the mechanism involved in the regulation of glucagon secretion from pancreatic alpha cells remains elusive. Dysregulated glucagon secretion is common in patients with Cystic Fibrosis (CF) that develop CF related diabetes (CFRD). CF is caused by a mutation in the Cl- channel Cystic fibrosis transmembrane conductance regulator (CFTR)

The large and sparsely hydrated thiocyanate anion, SCN–, plays a prominent role in the study of specific ion effects in biological, colloid, and atmospheric chemistry due to its extreme position in the Hofmeister series. Using atomistic modeling of aqueous SCN– solutions, we provide novel insight at the molecular scale into the experimentally observed differences in ion pairing, clustering, reorie

Harvesting the energy generated by photosynthetic organisms through light-dependent reactions is a significant step toward a sustainable future energy supply. Thylakoid membranes are the site of photosynthesis, and thus particularly suited for developing photo-bioelectrochemical cells. Novel electrode materials and geometries could potentially improve the efficiency of energy harvesting using thyl

Växelverkningar mellan små och stora molekyler har konsekvenser för reaktioner som kemister utför i sina provrör, lika mycket som för de livsnödvändiga reaktionerna som sker i vår kropp och våra celler. Förståelsen av dessa växelverkningar är nyckeln till att kunna utnyttja dem till vår fördel, till exempel i industriella processer eller i utveckling av mediciner. För att uppnå detta kan man utförThe influence of small and large, charged molecules on the properties of aqueous interfaces has important implications in chemistry, biology, and medicine. For example, at the surface of marine aerosols, the presence of halide anions and tropospheric gases gives way to multiphase chemical reactions affecting climate and air quality. In this Thesis, we investigate three different systems and phenom

Att arbeta som kassör vid utgångskassa anses vara ergonomiskt belastande. En vanlig uppfattning är att om kunden lägger varorna en och en på bandet samt vänder EAN-koden mot scannern, så minskar kassörens arbetsbelastning.Arbets- och miljömedicin Syd har i samarbete med Handelsanställdas Förbund genomfört en pilotstudie i kassaarbete vid scanning av varor. Pilotstudiens syfte är att undersöka om d

On 21 April 2018 Dutch government sent a reaction on the 2017 evaluations of the gift deduction and the charity rules to Dutch Parliament. Starting point of the reaction is that the gift deduction and the charity rules will be continued. However, government wants to improve the workability and enforceability. This article discusses the most important suggestions for changes of the government and t

The relationship between energy and capital is one of the most important aspects of modern economic growth. Machines need energy to produce all the goods we enjoy; energy would be far less useful for humankind in absence of machines. However, the great majority of the economic models do not take into account the elasticities of substitution (or complementaries) between these two main variables. Ac
