Stock market movements forecast based on sentiment analysis is certainly a field worth investigating. Being able to build future investment strategies based on forecasted stock returns would be of tremendous importance for individual investors and high-frequency trading firms. This thesis aims to closely investigate the impact that tweet sentiments in Twitter have on stock market movements; it int
The purpose of this study was to psychometrically test a Swedish translation of The Shame Inventory, originally developed by Rizvi (2010). Another purpose was to investigate the link between shame and psychopathology and specifically to borderline personality disorder. The psychometric properties of the Swedish version of The Shame Inventory were investigated, as well as the ability of the instrum
This paper describes an algorithm for reconstructing and identifying a highly collimated hadronically decaying τ-lepton pair with low transverse momentum. When two τ-leptons are highly collimated, their visible decay products might overlap, degrading the reconstruction performance for each of the τ-leptons. A dedicated treatment attempting to tag the τ-lepton pair as a single object is required. T
Wearable eye trackers and other glasses move on the wearer’s face. Such slippage can cause large offsets in the reported gaze position, and significant data loss. How much slippage may be expected during natural behavior? Here we report on the movement of two eye trackers and two smart glasses on the wearer’s head, recorded using a motion capture setup while thirty-five participants performed ten
This article investigates the potential of alternative research terminologyto facilitate the utilisation of existing geographical conceptions of spaceand place in empirical studies of children’s everyday lives. This isachieved by employing Clifford Geertz’s (1974. “‘From the Native’s Pointof View’: On the Nature of Anthropological Understanding.” Bulletin ofthe American Academy of Arts and Science
Surface tension is crucial for nanowire vapor liquid solid (VLS) growth models and simulations of growth under external stimuli. A promising method involving imaging droplet deformation under an external electric field has previously been used to report the surface tension of the AuSi eutectic catalyst on Si-nanowires. However, simplified assumptions in this approach led to a significantly lower v
The accuracy in determination of organ activity of Tc-99m was investigated, with activity estimated from gamma camera images of phantoms, using the, conjugate view method. The accuracy depends on several parameters such as the choice of background correction method, the accuracy in determination of the effective attenuation coefficient and the thickness of the body and organs and on the determinat
Abstract in UndeterminedVery large MIMO is a technique that potentially can offer large network capacities in multi-user scenarios where the users are equipped only with single antennas. In this paper we are investigating channel properties for a realistic, though somewhat extreme, outdoor base station scenario using a large array. We present measurement results using a 128 element linear array ba
A β-mannosidase was purified to homogeneity from the culture filtrate of Aspergillus niger. A specific activity of 500 nkat mg−1 and a 53-fold purification was achieved using ammonium sulfate precipitation, anion-exchange chromatography, and gel filtration. The isolated enzyme has an isoelectric point of 5.0 and appears to be a dimer composed of two 135-kDa subunits. It is a glycoprotein and conta
The major intrinsic proteins (MIPs) form a large protein family of ancient origin and are found in bacteria, fungi, animals, and plants. MIPs act as channels in membranes to facilitate passive transport across the membrane. Some MIPs allow small polar molecules like glycerol or urea to pass through the membrane. However, the majority of MIPs are thought to be aquaporins (AQPs), i.e., they are spec
A method of growing high-quality epitaxial Ge layers on a Si(100) substrate is reported. In this method, a 0.8 mum Si0.1Ge0.9 layer was first grown. Due to the large lattice mismatch between this layer and the Si substrate, many dislocations form near the interface and in the lower part of the Si0.1Ge0.9 layer. A 0.8 mum Si0.05Ge0.95 layer and a 1.0 mum top Ge layer were subsequently grown on the
Background Subjects in treatment for affective disorders are usually less satisfied with life compared to subjects with schizophrenia. Aims The aims of this study were to compare subjective quality of life (QoL) at adult age of adolescent onset psychotic disorders and analyse associated factors. Method Fifty-three patients with adolescent onset psychotic disorders were followed up at age 25, diagn
We have investigated the formation of supported bilayers by coadsorption of dipalmitoyl phosphatidylcholine (DPPC) with the nonionic surfactant P-D-dodecyl maltoside. The adsorption of mixed phospholipid-surfactant micelles on hydrophilic silica surfaces at 25 degrees C was followed as a function of bulk concentration by neutron reflection. Using chain-deuterated d(25)-beta-D-dodecyl maltoside and
