Channel modeling studies in vehicle-to-vehicle (V2V) communications have shown that larger road users act as blocking objects for the communication of surrounding vehicles, dramatically altering the statistical properties of the wireless channel. Without a strong line-of-sight component, packet delivery depends on other propagation mechanisms that are statistically more likely to add destructively

Background: The epidemiology of the zoonotic tick-transmitted parasite Babesia spp. and its occurrence in wild reservoir hosts in Sweden is unclear. In European deer, several parasite species, including Babesia capreoli and the zoonotic B. venatorum and B. divergens has been reported previously. The European roe deer, Capreolus capreolus, is an important and common part of the indigenous fauna in

The present work addresses critical issues in constructing high suppression, narrowband spectral filters in rare-earth-ion-doped crystals, mainly targeting the application of ultrasound optical tomography but is also applicable for areas such as quantum memories, self-filtering of laser frequencies, and other applications relying on high absorption in rare-earth-ion-doped crystals. The polarizatio

Tolerance is a distinguishing feature of Western culture. Still, it varies between and within countries, as well as over time, and irrespective of whether one values it for its own sake or for its beneficial consequences, it becomes important to identify its determinants. In this study, we investigate whether the character of economic policy plays a role, by looking at the effect of changes in eco

Reaction of Ru3(CO)12 with tris(2-thienyl)phosphine (PTh3) in CH2Cl2 at room temperature or in THF in the presence of a catalytic amount of Na[Ph2CO] furnishes the carbonyl substitution products Ru3(CO)11(PTh3) (1), Ru3(CO)10(PTh3)2 (2), and Ru3(CO)9(PTh3)3 (3). Heating 1 in toluene affords the cyclometalated cluster Ru3(CO)9{μ-Th2P(C4H2S)}(μ-H) (4) resulting from carbonyl loss and carbon-hydrogen

Romani chib har talats i Sverige i 500 år. Det är inte ett enhetligt, väldefinierat språk, som man kan skriva en enkel grammatik om. Tvärtom, i Sverige talas en stor mängd väldigt olika varianter av romani chib. Några har talats här länge, andra bara en kort tid.Boken fokuserar på de tre varianter som har talats längst i Sverige: skandoromani, kelderash och kale. Förutom språken behandlar boken ta

In a composite film of Cdx Sey Zn1-x S1-y gradient core-shell quantum dots (QDs) and gold nanorods (NRs), the optical properties of the QDs are drastically affected by the plasmonic nanoparticles. We provide a careful study of the two-step formation of the film and its morphology. Subsequently we focus on QD luminescence photoactivation - a process induced by photochemical changes on the QD surfac

In this paper, we have investigated, by means of quantitative and statistical methods, stability and change in cultural vocabulary of Indo-European in Europe, with a focus on agriculture. For this purpose we have created a culture vocabulary list with lexical head words, organized into subcategories based on their role and function in a cultural system, the purpose of which is to give a representa

Real-life environments have been used and framed as natural laboratories in which to study and develop new knowledge and understandings of human behaviour since the start of the last century (if not before). Likewise, urban researchers have been studying the phenomenon of urban experimentation for a long time (Bulkeley and Castán Broto 2013; Karvonen et al. 2014). Over the last decade, the city ha

We develop a formalism to study the tetraquark production in hadronic collisions. We focus on double parton scattering and formulate a version of the color evaporation model for the production of the T4c tetraquark, a state composed by the quarks. We find that the production cross section grows rapidly with the collision energy and the T4c might be observable at LHC energies.

Introduction: Hip fractures are commonly diagnosed by plain radiography. When a patient presents with negative radiographs and high clinical suspicion of fracture, guidelines recommend proceeding with magnetic resonance imaging (MRI) to diagnose the patient. The aim of this study was to assess the use of MRI in diagnosing hip fractures following trauma to the hip and describe clinical outcome afte

A high sperm DNA fragmentation index (DFI) is associated with reduced fertility. DFI is influenced by the balance between reactive oxygen species and antioxidants. A circannual variation in melatonin, an antioxidant and free radical scavenger, could thus impact semen quality and fertility. The association between the major melatonin metabolite, urine 6-sulfatoxymelatonin (aMT6s), and DFI was analy
