The effects of particle discreteness in N-body ACDM simulations are still an intensively debated issue. In this paper we explore such effects, taking into account the scatter caused by the randomness of the initial conditions and focusing on the statistical properties of the cosmological density field. For this purpose, we run large sets of ACDM simulations and analyze them using a wide variety of
In 2012, there were 11 000 accidents and near-miss reported of which most of it can be prevented. Though reporting and investigating injuries present a more detailed picture, this is still a lagging indicator — measuring after the event. Recording and investigating near misses, on the other hand, can be used as a positive indicator of performance tool to fix problems before injuries occur. Employe
This paper presents a study on how climate conditions at numerous locations in Sweden affect the risk of onset of mould on wood sheltered outdoors. The results indicate that the risk is clearly higher in the south compared to the north of Sweden. These differences are mainly explained by colder and dryer winter periods in the north which is unfavorable for development of mould. The results also sh
The article analyzes mechanisms established to control the fulfillment of the EU sustainability criteria for biofuels that were presented in Directive 2009/28/EC. The article is the continuation of the research started in the work Pavlovskaia, E. (2013) “Controlling the Fulfillment of the EU Sustainability Criteria for Transport Biofuels”, which was published in RELP 4/2013. The conducted analysis
Collective effects in MAX IV 3 GeV storage ring are strongly enhanced by the combination of low emittance, high current and small effective aperture. Three passive harmonic cavities (HC) are introduced to lengthen the bunches, by which beam stabilization is anticipated via decoupling to high frequency wakes, along with Landau damping. The role of the transverse impedance budget of the MAX IV 3 GeV
Thread Level Speculation at function level has been suggested as a method to automatically (or semi-automatically) extract parallelism from sequential programs. While there have been multiple implementations in both hardware and software, little work has been done in the context of dynamic programming languages such as JavaScript. In this paper we evaluate the effects of a simple Thread Level Spec

Wideband code division multiple access (WCDMA) systems are interference-limited. When a WCDMA system operates at nearly full capacity, admitting a new user may affect its stability. Therefore, proper call admission control (CAC) is crucial and should balance between quality of service (QoS) requirements for the new user as well as for the existing users and the required high capacity. In this pape

Gamma rays in the N=Z + 1 nucleus Y-79 were identified using the reaction Si-28(Fe-54, p2n)Y-79 at a 200 MeV beam energy and an experimental setup consisting of an array of Ge detectors and the Recoil Mass Spectrometer at Oak Ridge National Laboratory. With the help of additional gamma-gamma coincidence data obtained with Gammasphere, these gamma rays were found to form a strongly coupled rotation
Objective: To investigate the role of anti-cyclic citrullinated peptide antibody (anti-CCP) for the prediction of radiological outcome in patients with early rheumatoid arthritis. Methods: Anti-CCP was assessed at baseline in 379 patients with early rheumatoid arthritis ( disease duration <1 year). Radiological joint damage and progression were assessed by Larsen score after two years of follow up
Chlorophyll meters such as the SPAD-502 offer a simple, inexpensive and rapid method to estimate foliar chlorophyll content. However, values provided by SPAD-502 are unitless and require empirical calibrations between SPAD units and extracted chlorophyll values. Leaves of 13 tree species from the tropical rain forest in French Guiana were sampled to select the most appropriate calibration model am
A vertical gate symmetrical molecular transistor is demonstrated. It includes self assembled monolayer of ferrocene molecules chemically bonded to be a flat Au source and Au nanoparticles drain electrodes while gated with the central gate electrode. Using this configuration, we show that negative differential resistance, symmetrical behavior, and rectification effects can be tuned by controlling t
From 1997 to 2005, an astonishing 5200 million USD was invested to reduce cocaine production in Colombia, the world's main cocaine producer. However, little is known about the effectiveness of policies targeting coca cultivation. This paper uses a survey-based experiment to evaluate the effects of the two main policies: eradication and alternative development programs. Our results support Becker's
The purpose of building classification systems is to provide the sector with agreed and standardised ter¬minology and semantics, e.g. in systems for technical specification, cost calculation, and exchange of information. There is a growing need to use classification systems in a BIM context. In inter¬¬national construction projects and international construction product trade there is a need both
