Phase transition in random distance graphs on the torus

In this paper we consider random distance graphs motivated by applications in neurobiology. These models can be viewed as examples of inhomogeneous random graphs, notably outside of the so-called rank-1 case. Treating these models in the context of the general theory of inhomogeneous graphs helps us to derive the asymptotics for the size of the largest connected component. In particular, we show t

Applicability of the lattice Boltzmann method to determine the ohmic resistance in equivalent resistor connections

Knowing the ohmic resistance in the materials allow to know in advance its electrical behavior when a potential difference is applied, and therefore the prediction of the electrical performance can be achieved in a most certain manner. Although the Lattice Boltzmann method (LBM) has been applied to solve several physical phenomena in complex geometries, it has only been used to describe the fluid

Vitronectin

The multifaceted complement regulator vitronectin (Vn) can be found in almost all tissues of the human body. It is primarily produced by the liver and is thus detected at high concentrations in plasma. Upon inflammation, Vn is upregulated revealing its importance for the innate immune defence against danger signals. It consists of 459 amino acids and has several key sequences linked to its functio

Factor I

Factor I (FI) is a serine protease with narrow specificity restricted to activated complement components C3b and C4b. Supported by appropriate cofactors such as factor H or C4b-binding protein, FI cleaves peptide bonds in C3b/C4b after arginyl residues. By doing so it inhibits further propagation of the complement cascade thus contributing to protection from misguided or excessive complement attac

C4b-Binding Protein

C4b-binding protein (C4BP) is the main fluid-phase inhibitor of the classical complement pathway. It serves as cofactor in factor I-mediated cleavage of C4b and C3b and it accelerates the decay of complement convertases. The main role of C4BP is to prevent overt complement-mediated inflammation both in solution and on self-molecules recognised by C1q, such as amyloid. Furthermore, C4BP is frequent

Dynamic Allocation or Diversification : A Regime-Based Approach to Multiple Assets

This article investigates whether regime-based asset allocation can effectively respond to changes in financial regimes at the portfolio level in an effort to provide better long-term results when compared to a static 60/40 benchmark. The potential benefit from taking large positions in a few assets at a time comes at the cost of reduced diversification. The authors analyze this trade-off in a mul

Feminism and the Power of Love : Interdisciplinary interventions

The power of love has become a renewed matter of feminist and non-feminist attention in the 21st century’s theory debates. What is this power? Is it a form of domination? Or is it a liberating force in our contemporary societies?Within Feminism and the Power of Love lies the central argument that, although love is a crucial site of gendered power asymmetries, it is also a vital source of human emp

Love, Feminism and Dialectics : Repairing splits in theory and practice

Gunnarsson highlights how dialectics can shed light on the relation between love and dominance, foregrounding the crucial role that ontological tensions play in self–other relating. Drawing on Roy Bhaskar’s dialectical critical realist philosophy, she expands on Jessica Benjamin’s analysis of male dominance, as well as other feminist work, and elaborates on the necessity of living-with rather thanGunnarsson highlights how dialectics can shed light on the relation between love and dominance, foregrounding the crucial role that ontological tensions play in self–other relating.

The neologisms in 2 Maccabees

This thesis investigates a hitherto under-researched topic in Septuagint studies, the Septuagint neologisms, that is, the words which are first attested in the Septuagint, taking as a case in point a deuterocanonical/apocryphal book originally written in Greek, the Second Book of Maccabees (2 Maccabees). The thesis first examines how the neologisms have so far been treated in Septuagint studies an

Long-term exposure to ambient air pollution and incidence of postmenopausal breast cancer in 15 European cohorts within the ESCAPE project

BACKGROUND: Epidemiological evidence on the association between ambient air pollution and breast cancer risk is inconsistent. OBJECTIVE: We examined the association between long-term exposure to ambient air pollution and incidence of postmenopausal breast cancer in European women. METHODS: In 15 cohorts from nine European countries, individual estimates of air pollution levels at the residence wer

Skrivkrisgenren i historiskt ljus

För ett par år sedan rasade en tämligen hätsk mediedebatt om studenters skrivande. Debatten inleddes med ”ett veritabelt nödrop” då nio historiker i en artikel i Upsala Nya Tidning beklagade sig över studenters bristfälliga skrivande (Enefalk et al., 2013). Studenternas obefintliga historiekunskaper hade de fått förlika sig med för länge sedan, anförde de. Men nu, när till och med kommunikationsfö
