Context. On the order of 20% of the very metal-poor stars in the Galaxy exhibit large carbon enhancements. It is important to establish which astrophysical sites and processes are responsible for the elemental abundance patterns of this early Galactic population. Aims. We seek to understand the nature of the progenitors of three main-sequence turnoff Carbon-Enhanced Metal-Poor (CEMP) stars, CS 310
The development of biotechnological products is becoming more and more expensive. One type of protein attracting a great deal of attention in the biopharmaceutical industry is antibodies, which was used in this work. The cost of producing antibodies is, however, high, mainly due to the downstream processing, which constitutes 50–80% of the total cost. This work describes model-based methods to des
The concept of personality is scrutinized as used both in common parlance and in more sophisticated frames of reference. Current multidimensional models are criticized for their reliance on self-descriptive questionnaires and for their lack of a hierarchical dimension, differentiating more or less decisive determinants of behavior. A possible psychoanalytic model is viewed with more benevolence bu
Modelling of 2D resistivity imaging was done in order to understand the principle resolution of the technique in different geological situations, and for assessing the behaviour of the interpretation methods under controlled circumstances. The Wenner array was used throughout. The results show that the 1D approximation only provides reasonable results in environments with very gradual lateral resi
We propose and investigate a unifying class of sparse random graph models, based on a hidden coloring of edge-vertex incidences, extending an existing approach, random graphs with a given degree distribution, in a way that admits a nontrivial correlation structure in the resulting graphs. The approach unifies a number of existing random graph ensembles within a common general formalism, and allows
The article discusses the sociocultural dimensions to the Chinese courtesy titles 'nüshi' (ladies) and 'xiansheng' (gentlemen).
This paper reflects how anti-islanding protection has developed with increasing DG penetration. Starting from a local issue it has developed to possibly affect system security. The focus here is on how islanding detection methods and anti-islanding protection settings relate to distribution level and TSO requirements. It is confirmed using field measurements and simulations that the most common pa
The reaction of [Co2{μ-C2(CO2Me)2}(CO)6] with the ligand diphenyl-2-thienylphosphine, PPh2(C4H3S), yields the complexes [Co2{μ-C2(CO2Me)2}(CO)5{PPh2(C4H3S)}] (1) and [Co2{μ-C2(CO2Me)2}(CO)4{PPh2(C4H3S)}2] (2). The related complex [Co3(μ3CMe)(CO)9] reacts with the same ligand to give [Co3(μ3-CMe)(CO)8{PPh2(C4H3S)}] (3) and [Co3(μ3-CMe)(CO)7{PPh2(C4H3S))2] (4). Thermolysis of 1 at 80°C leads to part
Antigenic variation of surface proteins allows microorganisms to evade the immune system of the infected host. This phenomenon represents an apparent paradox, because the variable protein must retain an important function, while its antigenic properties vary extensively. The surface associated M protein of Streptococcus pyogenes, a common human pathogen, exhibits antigenic variation due to an N-te
Lifetimes of three levels belonging to the configuration 4f135d with J = 1 in Yb III have been measured for the first time using the time-resolved laser-induced fluorescence method. Experimental transition probabilities have been deduced for the transitions between the levels studied and the ground state. The comparison of the experimental lifetimes with theoretical data, deduced within the relati
This collection of essays explores the remarkable range and cultural significance of the engagement with 'infancy' during the Romantic period. Taking its point of departure in the commonplace claim that the Romantics invented childhood, the book traces that engagement across national boundaries, in the visual arts, in works of educational theory and natural philosophy, and in both fiction and non-
An overview of the cultural significance of Etna during the eighteenth century and Romantic period.
Circadian clocks were, until recently, seen as a consequence of rhythmic transcription of clock components, directed by transcriptional/translational feedback loops (TTFLs). Oscillations of protein modification were then discovered in cyanobacteria [1, 2]. Canonical posttranslational signaling processes have known importance for clocks across taxa [3, 4, 5, 6, 7, 8, 9, 10, 11]. More recently, evid
This thesis deals with estimation and classification problems of non-stationary processes in a few special cases.In paper A and paper D we make strong assumptions about the observed signal, where a specific model is assumed and the parameters of the model are estimated.In Paper B, Paper C, and Paper E more general assumptions about the structure of the observed processes are made, and the methods
