Research review (peer-reviewed)abstract
- Seed particles of elements or compounds which may or may not form alloys are now used extensively in promoting well-controlled nanowire growth. The technology has evolved following the well-known Vapour-Liquid-Solid (VLS) model which was developed over 40 years ago. This model indicates that a liquid alloy is formed from the seed particle and the growth precursor(s), resulting in crystal growth by precipitation from a supersaturated solution. The enhanced growth rate compared to the bulk growth from the vapour is typically attributed to preferential decomposition of precursor materials at or near the particle surface. Recently, however, there has been much interest in further developing this model, which was developed for Au-assisted Si whiskers (with diameter on the micrometre scale), in order to generally describe particle-assisted growth on the nanoscale using a variety of materials and growth systems. This review discusses the current understanding of particle-assisted nanowire growth. The aim is first to give an overview of the historical development of the model, with a discussion of potential growth mechanisms. In particular, the enhancement of growth rate in one dimension due to preferential deposition at the particle-wire interface will be discussed. Then, the particular example of Ill-V nanowires grown by metal-organic vapour phase epitaxy using Au particles will be revised, with details of the various growth processes involved in this system. The aim of this review is not to provide a conclusive answer to the question of why nanowires grow from seed particle alloys, but to describe the progress made towards this goal of a unified theory of growth, and to clarify the current standing of the question.

Journal article (other academic/artistic)abstract
- Background: High intakes of whole-grains and cereal fiber have been consistently associated with lower risk of cardiometabolic diseases in observational studies. Yet, improved understanding about the underlying mechanisms is needed. We hypothesized that cereal fiber and whole-grain are associated with beneficial metabolic marker profiles.Aim: To investigate if cereal fiber intake, estimated by food frequency questionnaires and plasma total alkylresorcinols concentrations as well as the C17:0/C21:0-ratio in plasma as biomarkers of whole-grain wheat and rye intake or the relative whole-grain rye to wheat intake, respectively, were associated with metabolic biomarkers.Design: A cross-sectional study conducted to investigate the associations between alkylresorcinols as biomarker of whole-grain wheat and rye intake, cereal fiber and selected metabolic biomarkers among 954 participants of the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Cereal fiber intake was assessed by FFQ and whole grain wheat and rye were reflected by biomarkers analyzed in plasma samples, i.e. total alkylresorcinol (AR). Moreover, the ratio of two of the five measured alkylresorcinols (AR C17:0/C21:0 ratio) was used as an indicator of whole-grain source (wheat or rye). Metabolic biomarkers (HbA1c, C-peptide, IGFBP-1, IGFBP-2, total cholesterol, LDL, HDL, triglycerides, apolipoprotein A-I (apoA), apolipoprotein B (ApoB) and CRP) were measured in blood samples. All biomarkers were already measured for nested case-control studies of colorectal cancer matched based on sex, study center, age at blood collection, date and time of blood collection, fasting status. Women were further matched by menopausal status, phase of menstrual cycle, and use of oral contraceptives or hormone replacement therapy at time of blood collection. Multivariable linear regression analysis was used to investigate the relationship between exposure variables metabolic biomarkers adjusted for case-control status and common confounders.Results: No associations were found between cereal fiber intake and the metabolic markers. However, whole-grain wheat and rye intake, reflected by total AR, was associated with a lower concentration of the inflammation marker CRP. The alkylresorcinol C17:0/C21:0 ratio was not associated with any of the measured metabolic markers in this cohort.Conclusion: Overall, we found no support for an association between cereal fibre intake, whole grain wheat and rye intake reflected by biomarkers and metabolic markers in the present cohort. One exception was the finding of an inverse association between whole grain biomarkers and CRP. Prospective studies or RCTs are warranted to confirm our findings.

Building Beliefs : Unsupervised Generation of Observation Likelihoods for Probabilistic Localization in Changing Environments
- 2015
-
In: IEEE International Conference on Intelligent Robots and Systems (IROS), IEEE, 2015. - New York, USA : IEEE. - 9781479999941 ; , s. 3071-3078

Conference paper (peer-reviewed)abstract
- This paper is concerned with the interpretation of visual information for robot localization. It presents a probabilistic localization system that generates an appropriate observation model online, unlike existing systems which require pre-determined belief models. This paper proposes that probabilistic visual localization requires two major operating modes - one to match locations under similar conditions and the other to match locations under different conditions. We develop dual observation likelihood models to suit these two different states, along with a similarity measure-based method that identifies the current conditions and switches between the models. The system is experimentally tested against different types of ongoing appearance change. The results demonstrate that the system is compatible with a wide range of visual front-ends, and the dual-model system outperforms a single-model or pre-trained approach and state-of-the-art localization techniques.

Lack of correlation between NADPH-oxidase priming and elevated alkaline phosphatase activity in cord blood neutrophils.
- 1995
-
In: Pediatric allergy and immunology : official publication of the European Society of Pediatric Allergy and Immunology. - 0905-6157. ; 6:3, s. 161-4
-
Journal article (peer-reviewed)abstract
- Human neutrophils were isolated from cord blood drawn after Caesarean section deliveries without labour and from peripheral blood from healthy adults. The alkaline phosphatase (ALP) activity in the cell populations was compared with the release of respiratory burst products after activation with the chemoattractant n-formyl-methionyl-leucyl-phenylalanine (fMLP). In contrast to cord blood neutrophils obtained from babies after normal vaginal deliveries, the Caesarean section neutrophils were not metabolically primed. However, like the neutrophils from vaginally delivered babies, the Caesarean section neutrophils showed an increased ALP activity compared to adult control neutrophils. These findings indicate that priming of cord blood neutrophils appears to be induced by labour and can be dissociated from increased ALP activity.

Latin and Vernacular Homilies of Anglo-Saxon England : Preaching and Perceptions of Society
- 2013
-
Conference paper (other academic/artistic)abstract
- The advances in the study of homiletic writing of Anglo-Saxon England in the past few decades have made it possible to situate many seemingly formulaic and conventional texts in their specific historical contexts, and to perceive in them certain participation in and commentary on the contemporary social and political situation. This pertains especially to homilies written in Old English – the long-term primary interest of Anglo-Saxon scholarship – which may at times seem to overshadow the coexistent Latin culture. This paper pays attention to this division and explores both Latin and vernacular homiletic writing from the perspective of preaching and social perception. It examines the features of Latin and Old English as languages of teaching, and then discusses Archbishop Wulfstan’s (ca. 950-1023) Latin sermons as a case study, especially those in one of his own ‘Commonplace Books’, Copenhagen Kongelige Bibliotek, Gl. Kgs. Sam. 1595. From the outset, the linguistic division appears to have many fundamental implications for both composition and delivery: the Latin sermons and homilies were for the most part meant to be used in the monastic office, whereas the vernacular ones are thought to have served the needs of lay preaching or private devotion. In terms of social perception, therefore, preaching on social order, vices and virtues, or rules and responsibilities would have found its audiences in different social categories, at least in theory. In practice, the boundaries between these categories were much more fluid, and the language of a text in itself does not always denote a certain audience. The act of preaching as a potentially infuential type of medium in circulating ideas and conceptions on social order makes the two corpora essential sources for studying social ideas, their implementation and authorization. Consequently, the paper contributes to the discussion of both oral and literary as well as the Latin and vernacular communication in the Middle Ages.

Journal article (peer-reviewed)abstract
- Immunoglobulin G (IgG) is the most abundant serum antibody which structural characteristics and effector functions are modulated through the attachment of various sugar moieties called glycans. Composition of the IgG N-glycome changes with age of an individual and in different diseases. Variability of IgG glycosylation within a population is well studied and is known to be affected by both genetic and environmental factors. However, global inter-population differences in IgG glycosylation have never been properly addressed. Here we present population-specific N-glycosylation patterns of IgG, analyzed in 5 different populations totaling 10,482 IgG glycomes, and of IgG's fragment crystallizable region (Fc), analyzed in 2,579 samples from 27 populations sampled across the world. Country of residence associated with many N-glycan features and the strongest association was with monogalactosylation where it explained 38% of variability. IgG monogalactosylation strongly correlated with the development level of a country, defined by United Nations health and socioeconomic development indicators, and with the expected lifespan. Subjects from developing countries had low levels of IgG galactosylation, characteristic for inflammation and ageing. Our results suggest that citizens of developing countries may be exposed to environmental factors that can cause low-grade chronic inflammation and the apparent increase in biological age.
