Nonasymptotic Regret Analysis of Adaptive Linear Quadratic Control with Model Misspecification

The strategy of pre-training a large model on a diverse dataset, then fine-tuning for a particular application has yielded impressive results in computer vision, natural language processing, and robotic control. This strategy has vast potential in adaptive control, where it is necessary to rapidly adapt to changing conditions with limited data. Toward concretely understanding the benefit of pre-tr

Fuktegenskaper hos betonger med slagginblandning

Fuktegenskaper hos fem betonger med olika grad av inblandning av slagg har bestämts. Desorptionsisotermer har mätts på tunna skivor i klimatboxar. Fukttransportkoefficienter har bestämts med koppmetoden på välhärdade prover och med burkmetoden på prover som härdats i 3, 6 respektive 12 månader.Desorptionsisotermerna uppvisar en horisontell ”platå” i området 85-95 % RF, särskilt vid slagginblandnin

Bacterial profile in human atherosclerotic plaques

Background and aimsSeveral studies have confirmed the presence of bacterial DNA in atherosclerotic plaques, but its contribution to plaque stability and vulnerability is unclear. In this study, we investigated whether the bacterial plaque-profile differed between patients that were asymptomatic or symptomatic and whether there were local differences in the microbial composition within the plaque.

Oral microbiota in patients with atherosclerosis

Background and aims: Recent evidence suggests that the microbiota may be considered as an environmental factor that contributes to the development of atherosclerosis. Periodontal disease has been associated with cardio- and cerebrovascular events, and inflammation in the periodontium is suggested to increase the systemic inflammatory level of the host, which may in turn influence plaque compositio

Impact of gut microbiota and diet on the development of atherosclerosis in ApoE−/− mice

Objective: To investigate the effect of gut microbiota and diet on atherogenesis. Approach and Results: Here, we investigated the interaction between the gut microbiota and diet on atherosclerosis by feeding germ-free or conventionally raised Apoe−/− mice chow or Western diet alone or supplemented with choline (which is metabolized by the gut microbiota and host enzymes to trimethylamine N-oxide)

A prebiotic oligofructose-enriched inulin preparation stimulates intestinal growth and function in suckling rats

Postnatal development of the gastrointestinal (GI) tract in mammals is influenced, to an unknown extent, by the diet and the microflora. The aim of the current study was to clarify the role of a dietary fibre on postnatal Gl development, by studying the effects of aprebiotic oligofructose-enriched inulin preparation (Synergy 1) on GI growth and function in a suckling rat modcl Between 10 and 16 da

A Deep Learning Biomimetic Milky Way Compass

Moving in straight lines is a behaviour that enables organisms to search for food, move away from threats, and ultimately seek suitable environments in which to survive and reproduce. This study explores a vision-based technique for detecting a change in heading direction using the Milky Way (MW), one of the navigational cues that are known to be used by night-active insects. An algorithm is propo

N exus : A framework for controlled simulations of idealized galaxies

Motivated by the need for realistic, dynamically self-consistent, evolving galaxy models that avoid the complexity of full, and zoom-in, cosmological simulations, we have developed Nexus, an integral framework to create and evolve synthetic galaxies made of collisionless and gaseous components. Nexus leverages the power of publicly available, tried-and-tested packages: the stellar-dynamics, action

Family History of Diabetes and Clinical Characteristics in Children at Diagnosis of Type 1 Diabetes—A Swedish Population-Based Study

OBJECTIVE To compare the prevalence of parental diabetes between children with and without type 1 diabetes (T1D), and to compare clinical characteristics at diagnosis of T1D in children with, versus without, a family history of diabetes. RESEARCH DESIGN AND METHODS Parental diabetes among children with T1D was compared with a general population cohort. Clinical characteristics were compared by fam

Who can I be now? The complexity of students in policy enactment

This paper aims to contribute to the field of policy enactment studies with a deepened understanding of the significance of the students when a pedagogical vision is enacted. The paper is based on a single case study using observations, surveys, interviews, and document studies. Informed by policy enactment theory, we analyse the students’ role in enacting the vision at the newly established Newsc

Enhancing iron and zinc bioavailability in maize (Zea mays) through phytate reduction : the impact of fermentation alone and in combination with soaking and germination

Introduction: Phytates are nutrient-binding compounds found mainly in cereals and legumes, which may significantly contribute to micronutrient malnutrition in regions where phytate-rich cereals, such as maize, are staple food.Objectives: This study investigated how maize fermentation, both alone and in combination with soaking and germination, can reduce phytate levels and enhance the estimated bi

MHC Class II Supertypes Affect Survival and Lifetime Reproductive Success in a Migratory Songbird

The major histocompatibility complex (MHC) plays a critical role in the immune response against pathogens. Its high polymorphism is thought to be mainly the consequence of host-pathogen co-evolution, but elucidating the mechanism(s) driving MHC evolution remains challenging for natural populations. We investigated the diversity of MHC class II genes in a wild population of pied flycatchers Ficedul

Issues in systematizing the elicitation and analysis of syllable structure

This reply explores issues with documenting prosodic structures given their unique relationship with metalinguistic knowledge. New evidence and perspectives are incorporated into a deeper investigation of Budai Rukai and the analytical decisions that underlie its reanalyzed prosodic system. This case study is then taken as a basis for discussion of a possible standardized protocol for the document
