Convolutional Neural Networks (CNNs) and pre-trained word embeddings have revolutionized the field of Natural Language Processing (NLP) during the last years. In this project, CNNs are used on top of the Word2Vec word representation for a sentence classification task on medical research articles. Both individual networks for each category as well as a combined classification network are optimized
A simplified interaction potential for protein folding studies at the atomic level is discussed and tested on a set of peptides with; 20 residues each. The test set contains both alpha-helical ( Trp cage, F-s) and beta-sheet ( GB1p, GB1m2, GB1m3, Betanova, LLM) peptides. The model, which is entirely sequence-based, is able to fold these different peptides for one and the same choice of model param
Denna studie intresserar sig för när en organisations förtroende sätts på spel. Kriskommunikation är i fokus och mer specifikt hur modejätten NA-KD har hanterat ett försök till bojkott, vilket kan kopplas till det aktuella fenomenet cancel culture. Studiens primära syfte handlar om att öka förståelsen för hur organisationer som utsätts för en liknande kris online kan hantera dessa med hjälp av resThis study is interested in when an organization's trust is exposed. Crisis communication is in focus and more specifically how the fashion giant NA-KD has handled an attempt to boycott, which can be linked to the current phenomenon of cancel culture. The primary purpose of the study is to increase the understanding of how organizations that are exposed to a similar crisis online can handle th
Häktning är det mest ingripande av våra personella tvångsmedel. Oskyldig eller inte följer det av svensk lag att varje intagen ska behandlas med respekt för sitt människovärde. Vidare ska verkställigheten av häktningen utformas så att negativa följder motverkas, med sådana följder avses bland annat psykiska, sociala och ekonomiska konsekvenser som kan följa av ett frihetsberövande. Om det finns riPre trial detention is a coercion measure where a suspect is incarcerated between the time he or she is being arrested until the trial. A pre trial detainee is considered innocent until proven guilty and thus it is important that the detention is not used as a punishment or rehabilitation. Whether a detainee is innocent or not he or she should be treated with respect for his or her human dignity.
Cambodia´s complicated political landscape has created a development context that the international community long struggled to navigate. In this paper I – through a theoretical framework that conceptualises a political context as a historically located totality and defines the quest for political legitimacy as a constraint that can be used to make inferences about the behaviour and actions prefer
New stable particles with fairly low masses could exist if the coupling to the Standard Model is weak, and with suitable parameters they might be possible to produce at the LHC. Here we study a selection of models with the new particles being charged under a new gauge group, either U(1) or SU(N). In the Abelian case there will be radiation of gammavs, which decay back into the SM. In the non-Abeli
This thesis considers the low-energy effective field theory of a new technicolor extension. The extension preserves the Standard Model Higgs boson and introduces a chirally symmetric technifermion sector, in the framework of the gauged linear sigma model. In the nearly conformal limit, the considered extension leads to a common origin of the Higgs- and Technisigma vacuum expectation values, relate
In this thesis, a holographic model for quantum chromodynamics (QCD) is used to estimate the electromagnetic contribution to the kaon mass difference. The principal ideas of the model are inspired by the AdS/CFT correspondence, which is believed to be exact. The calculation is first performed theoretically, highlighting the expansion of the result into a diagrammatic structure referred to as Witte
Heavy long-lived quarks, i.e. charm and bottom, are frequently studied both as tests of QCD and as probes for other physics aspects within and beyond the standard model. The long lifetime implies that charm and bottom hadrons are formed and observed. This hadronization process cannot be studied in isolation, but depends on the production environment. Within the framework of the string model, a maj
In this paper the Poisson bracket algebra for the open massless relativistic string in the one-space-and one-time-dimensional case is considered. In order to characterize the orbit of the system the directrix function, i.e., the orbit of one of the endpoints of the string, is used. It turns out that the Poisson bracket algebra is of a very simple form in terms of the parameters of the directrix fu
We study the thermodynamic behavior of a simple off-lattice model for protein folding. The model is two dimensional and has two different "amino acids." Using numerical simulations of all chains containing eight or ten monomers, we examine the sequence dependence at a fixed temperature. It is shown that only a few of the chains exist in unique folded state at this temperature, and the energy level
