2. 16. Generic Properties of Polymer Solutions

   Author : Takashi Uematsu; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; photon correlation spectroscopy; collective diffusion; atomic force microscopy; relaxation; agarose gel electrophoresis; DNA; Zimm dynamics; pulsed-field gradient NMR; superdiffusion; polymer solution; blob model; gel;

   Abstract : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. READ MORE

5. 18. Predicting Linguistic Structure with Incomplete and Cross-Lingual Supervision

   Author : Oscar Täckström; Joakim Nivre; Jussi Karlgren; Ryan McDonald; Hal Daumé III; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; linguistic structure prediction; structured prediction; latent-variable model; semi-supervised learning; multilingual learning; cross-lingual learning; indirect supervision; partial supervision; ambiguous supervision; part-of-speech tagging; dependency parsing; named-entity recognition; sentiment analysis; Computational Linguistics; Datorlingvistik;

   Abstract : Contemporary approaches to natural language processing are predominantly based on statistical machine learning from large amounts of text, which has been manually annotated with the linguistic structure of interest. However, such complete supervision is currently only available for the world's major languages, in a limited number of domains and for a limited range of tasks.

6. 19. Simulating Functional Cycles and Drug Modulation in Ligand-gated Ion Channels

   Author : Yuxuan Zhuang; Erik Lindahl; Grace Brannigan; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ion channels; molecular dynamics; markov state model; lipid modulation; nicotinic receptor; protein conformational transitions; Biophysics; biofysik;

   Abstract : Understanding the intricate motions and conformational changes that govern biological processes remains a fascinating and challenging endeavor. The research presented in this thesis aims to elucidate the dynamic processes underlying biological functions, specifically focusing on the dynamics of pentameric ligand-gated ion channels (pLGICs), which play a crucial role in signal transduction within the brain.

7. 20. Assessing the structural and dynamical properties of concentrated solutions of the disordered proteins Histatin 5 and its tandem repeat

   Author : Eric Fagerberg; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Simulation; IDP; crowding;

   Abstract : Intrinsically disordered proteins are distinguished by a lack of distinct three-dimensional structure, existing instead as an ensemble of heterogenous structures. In this research, the effect of crowding on these proteins is investigated using a combined approach of experiment and computer simulation, mainly using coarse-grained simulation models to make simulation computationally feasible at the high concentration conditions crowding is displayed.
