11. Entanglement detection schemes and coherent manipulation of spin in quantum dots
Sammanfattning : The work contained in this thesis deals with two closely related topics. Papers I-III deal with charge transport statistics in nanoscale devices to investigate the presence of entanglement in the constituent electrons. We identify the contributions of entangled electron pairs to the current cross-correlations as a signature of entanglement. LÄS MER
12. Changes in gene expression during delayed neuronal death after cerebral ischemia in the rat
Sammanfattning : After transient global cerebral ischemia, selected populations of neurons in the brain will die after a period of 2-3 days, a phenomenon termed delayed neuronal death. This is of clinical importance as delayed neuronal death has been found to occur in humans as well. LÄS MER
13. Control and Communication with Signal-to-Noise Ratio Constraints
Sammanfattning : This thesis is about two problems in the intersection of communication and control theory. Their common feature is that they involve communication over an additive white noise channel with a signal-to-noise ratio (SNR) constraint. The first problem concerns the transmission of a real-valued signal from a partially observed Markov source. LÄS MER
14. MHC polymorphism and host-pathogen interactions: The case of Borrelia in its reservoir host, the bank vole Myodes glareolus
Sammanfattning : The major histocompatibility complex (MHC) class IIB genes exhibit extensive allelic polymorphism, most likely maintained by pathogen-mediated balancing selection (PMBS). PMBS may operate in the form of heterozygote advantage (HA), and/or through the interaction of pathogens and specific MHC alleles via fluctuating selection (FS) or negative frequency-dependent selection (NFDS).

15. Antonyms in Context : A Corpus-Based Semantic Analysis of Swedish Descriptive Adjectives
Sammanfattning : How are antonym relations acquired? What types of lexical information can be extracted from corpora and how? How can this information be encoded in a lexicon? The work in this book was developed within the framework of WordNet. A further elaborated lexical model is suggested, as well as methods for implementing it. LÄS MER
