In the recent years, cryptocurrencies have gained popularity and have experienced high price volatility. This essay pretends to examine how the multivariate GARCH models predict the volatility of these digital currencies and what implications exist if we consider the correlations among them to forecast their volatility. Using a bivariate Diagonal VECH and bivariate Diagonal BEKK this thesis checks
Presented here is an engineered protein domain, based on Protein A, that displays a calcium-dependent binding to antibodies. This protein, ZCa, is shown to efficiently function as an affinity ligand for mild purification of antibodies through elution with ethylenediaminetetraacetic acid. Antibodies are commonly used tools in the area of biological sciences and as therapeutics, and the most commonl
Video capsule endoscopy (VCE), perfomed by ingesting a small vitamin-sized camera pill, was developed over a period of a couple of decades and –since its introduction in clinical practice at the dawn of the millennium– has become an essential tool in the diagnosis and management of small bowel (SB) diseases. At the same time, other fields such as minimally invasive diagnosis of other parts of the
Every single State has its own rules: legal persons are created based on the domestic laws and States tax them according to their own tax laws. Thus, differences and imperfect legal relationships are inevitable at the international level. The existence of legal entities formed under diverse domestic laws which are not similar to each other leads to disparities and thus, to difficulties to have a c
Information system have become exceedingly important in our daily working lives and by that tightly connected with jobs. Job satisfaction is relatively explored research field which has become very popular in the last decades. But how do information systems affect other aspects of work, and how does our perception of our working life affect our acceptance of information systems is relatively unexp
We show that the common claim that internal validity should be understood as prior to external validity has, at least, three epistemologically problematic aspects: experimental artefacts, the implications of causal relations, and how the mechanism is measured. Each aspect demonstrates how important external validity is for the internal validity of the experimental result.
The polyamines putrescine, spermidine, and spermine are organic cations that are required for cell growth and differentiation. Ornithine decarboxylase (ODC), the first and rate-limiting enzyme in the polyamine biosynthetic pathway, catalyzes the conversion of ornithine to putrescine. As the polyamine biosynthetic pathway is essential for the growth and survival of Leishmania donovani, the causativ
In a ceremony held on June 21, the brightest day of the year in the northern hemisphere, Swedish Prime Minister Stefan Löfven and H.M. King Carl XVI Gustaf, together with Director Christoph Quitmann, inaugurated MAX IV Laboratory in the presence of about 500 staff, funders, stakeholders, and guests from all over the world.
Multiple missiles were fired at Erbil on February 15, killing at least one civil contractor and injuring at least one American national. It is likely that the attack was conducted by an Iranian proxy in order to put pressure on President Biden to lift the sanctions against the country and return to the 2015 nuclear deal.
I will show that what is respected the most in human reproduction and parenting is not a right to reproduce in the way in which this right is explicitly proposed. The only way in which people can become, and function as, parents without having to submit themselves to anyone else’s judgments and decisions, is by having reproductive sex. Whatever one’s intentions, social status, standard of living,
South Korea is attempting to deal with the now-universal issue of disinformation. So why did its draft bill attract such fierce criticism?
The purpose of the present research was to examine if anxiety is linked to a memory-based attentional bias, in which attention to threat is thought to depend on implicit learning. Memory-based attentional biases were defined and also demonstrated in two experiments. A total of 168 university students were shown a pair of faces that varied in their emotional content (angry, neutral, and happy), wit
