Background and ObjectivesIdentifying a clinically meaningful change in cognitive test score is essential when using cognition as an outcome in clinical trials. This is especially relevant because clinical trials increasingly feature novel composites of cognitive tests. Our primary objective was to establish minimal clinically important differences (MCIDs) for commonly used cognitive tests, using a
Abstract in SpanishSe ha dicho a menudo que la Cronografía de Miguel Psellós, el prolífico autor del s. xi, es una obra historiográfica que semeja una novela y que Psellós gasta mucho tiempo en describir caracteres y en tomar actitudes irónicas respecto de sus protagonistas imperiales. Este artículo sostiene que una versión más refinada de esto puede ser vista en el libro sexto de Psellós a pIt has often been stated that the Chronographia by the eleventh-century prolific author Michael Psellos is a piece of historiography that reads almost like a novel, and that Psellos spends much time on describing characters and taking ironical stances towards his imperial protagonists. This article claims that a refined version of this may be seen in Psellos’ book six on Constantine IX Monomachos.
For many years, fascism in East Central and Southeastern Europe remained an overlooked aspect of the history of transnational and transatlantic fascism. This introduction provides a background on how this came to pass and why we should rethink this assumption. The introduction explains how the heterogeneity of East Central and Southeastern European fascism alters the general understanding of Europ
AIMS: Metformin has hitherto not been proven superior to other type 2 diabetes (T2D) medications for the prevention of organ complications. The aim of this study is to report baseline data and blinded interim analyses in the register-based randomised clinical trial (RRCT) SMARTEST, which compares metformin and the SGLT2 inhibitor dapagliflozin in early T2D. We also present learnings from the novel
Dynamic processes in catalysis are gaining increased attention and could very well be one of the next frontiers in surface science. One way to study such processes is to induce chemical changes on the surface for example by periodically adjusting the (electro)chemical potential in situ and identify the resulting spectral changes. Often this is referred to as Modulation Excitation Spectroscopy (MES
This study examines the characteristics and nature of rumor via mobile communication in contemporary China. By focusing on six concrete case studies with 50+ in-depth interviews, this study observes that mobile phone-mediated rumor has evolved into a special form of popular resistance at the grassroots level. The low-cost and user-friendly mobile device lowers the average protest threshold, creati

Cloud computing has recently received considerable attention, as a promising approach for delivering ICT services by improving the utilisation of data centre resources. On the other hand, the increased usage of ICT, jointly with the increased cost of energy, make designing and managing data centres with energy efficient strategies a crucial and strategical problem. In the literature there are man
This thesis describes analysis of data from the DELPHI Very Small Angle Tagger (VSAT) calorimeter at LEP1. The VSAT consists of four Silicon-Tungsten calorimeter modules symmetrically positioned 7.7 meters away from the interaction point. It measures elastically scattered electrons and positrons, Bhabha events, within the polar angular region between 5-12 mrad. Trigger efficiency and reconstructio
The purpose of the present study was threefold: (a) to replicate the finding by MacLeod and Rutherford (1992) that low trait-anxious individuals, in contrast to high trait-anxious individuals, show a selective attention away from subliminally presented threat words at elevated levels of stress; (b) to test the hypothesis that this effect is due to individuals with repressive coping-style rather th
In many-body and other systems, the physics situation often allows one to interpret certain, distinct states by means of a simple picture. In this interpretation, the distinct states are not eigenstates of the full Hamiltonian. Hence, there is an interaction that makes the distinct states act as doorways into background states which are modeled statistically. The crucial quantities are the overlap
In comparison to other insects, like honeybees, bumblebees are very effective pollinators. Even though landing is a crucial part of pollination, little is known about how bumblebees orchestrate the final, critical moments of landing. Here, we use high-speed recordings to capture the fine details of the landing behaviour of free-flying bumblebees (Bombus terrestris), while landing on a flat platfor
In high performance concrete (HPC) with low water-cement ratio, cement reaction will cause substantial drying expressed in terms of relative humidity (RH) of the pore water. This phenomenon is called self-desiccation. The RH-values as low as 85% have been measured in dense concretes that have been stored for more than 18 months in water. This means that there is almost no freezable water in the co
This paper presents results of an all-sky search for periodic gravitational waves in the frequency range [50, 1190] Hz and with frequency derivative range of similar to[-20, 1.1] x 10(-10) Hz s(-1) for the fifth LIGO science run (S5). The search uses a noncoherent Hough-transform method to combine the information from coherent searches on time scales of about one day. Because these searches are ve
We apply first- and second-order splitting schemes to the differential Riccati equation. Such equations are very important in e.g. linear quadratic regulator (LQR) problems, where they provide a link between the state of the system and the optimal input. The methods can also be extended to generalized Riccati equations, e.g. arising from LQR problems given in implicit form. In contrast to previous
A very simple and extremely computationally efficient algorithm for blind separation of two speech sources from two mixtures is presented in this paper. The algorithm exploits the approximate W-disjoint orthogonality of speech signals and assumes specific sensors (microphones) setting that allows the sources to possess a feature we call cross high-low diversity. Two sources are said to be cross hi
With todays increased use of smartphones and other wireless devices, the demands on the wireless networks have increased dramatically. This has prompted the re- search and development of new types of wireless systems using multiple antennas at both the transmitter and the receiver, known as MIMO. Since wireless systems are very susceptible to interference and to changes in the environment, it is i
The high-luminosity phase of LHC operations (HL-LHC), will feature a large increase in simultaneous proton-proton interactions per bunch crossing up to 200, compared with a typical leveling target of 64 in Run 3. Such an increase will create a very challenging environment in which to perform charged particle trajectory reconstruction, a task crucial for the success of the ATLAS physics program, an
