Animals flying in the wild often show remarkable abilities to negotiate obstacles and narrow openings in complex environments. Impressive as these abilities are, this must result in costs in terms of impaired flight performance. In this study, I used a budgerigar as a model for studying these costs. The bird was filmed in stereo when flying through a wide range of gap widths from well above wingsp

BACKGROUND: Limited evidence exists to guide the management of patients with liver metastases from squamous cell carcinoma (SCC). The aim of this retrospective multicentre cohort study was to describe patterns of disease recurrence after liver resection/ablation for SCC liver metastases and factors associated with recurrence-free survival (RFS) and overall survival (OS). METHOD: Members of the Eur

The demand for availability of efficient and safe contraceptive methods is strengthened by the predic-tions made by the United Nations regarding the future growth of the human population. So far, women are not only the main victims of the unsafe procedures related to terminating unwished pregnancies but do also carry the main responsibility for family planning. There is a significant desire among

This chapter is an attempt to assess how the turn to history has affected the ways in which war is understood within the study of international relations. After briefly describing what has been at stake in the recent turn to history, the chapter explores how war has been conceptualized in some prominent works within historical international relations. I argue that three things have happened to the

The Roman Republic expanded and evolved into the Roman Empire. Institutions and impulses from this evolution conditioned nations, shaped states and affected the nature of modern interstate history; indeed, effects of ancient Rome - the Republic as well as the Empire - are still visible in the ordering institutions and in the conflict lines of contemporary International Relations. This chapter, fir

The building blocks of Titan and Enceladus are believed to have formed in a late-stage circumplanetary disk (CPD) around Saturn. Evaluating the evolution of the abundances of volatile species in this disk as a function of the migration, growth, and evaporation of icy grains is then of primary importance to assess the origin of the material that eventually formed these two moons. Here we use a simp

Aromatic side chains are attractive probes of protein dynamic, since they are often key residues in enzyme active sites and protein binding sites. Dynamic processes on microsecond to millisecond timescales can be studied by relaxation dispersion experiments that attenuate conformational exchange contributions to the transverse relaxation rate by varying the refocusing frequency of applied radio-fr

Ammonia is regarded as a potential carbon-free alternative fuel. To have a better understanding of its combustion characteristics, development of feasible techniques for ammonia detection in combustion environments is essential. In the present work, planar laser-induced photofragmentation fluorescence (LIPF) was developed for quantitative measurements of ammonia in hot gas flows. A 193 nm ArF exci

Urbanisation is proceeding at an alarming rate which forces wildlife to either retreat from urban areas or cope with novel stressors linked to human presence and activities. For example, urban stressors like anthropogenic noise, artificial light at night and chemical pollution can have severe impacts on the physiology of wildlife (and humans), in particular the immune system and antioxidant defenc

In this paper we derive error estimates of the backward Euler–Maruyama method applied to multi-valued stochastic differential equations. An important example of such an equation is a stochastic gradient flow whose associated potential is not continuously differentiable but assumed to be convex. We show that the backward Euler–Maruyama method is well-defined and convergent of order at least 1/4 wit

Aim: This pooled analysis evaluated the safety and tolerability of the subcutaneous immunoglobulin 20% product, Ig20Gly, in primary immunodeficiency diseases using data from two Phase II/III studies conducted in North America and Europe. Patients & materials/methods: Patients received Ig20Gly (volumes, ≤60 ml/site; rates, ≤60 ml/h/site). Adverse events (AEs), tolerability and infusion paramete

Psychiatric comorbidity is common in gambling disorder (GD), but there are few studies on larger nationwide samples of treatment-seeking patients. Also, temporal associations between GD and other psychiatric disorders are often difficult to study. To address the prevalence and the temporal associations of prescriptions for psychiatric disorders — both in specialized care and primary care — in pati

Background and purpose: Patients with focal cartilage lesions experience functional impairment. Results for biological treatments in the middle-aged patient is poor. Previous studies with focal prosthetic inlay resurfacing have shown a higher risk of conversion to total knee replacement at mid-term follow-up. A novel customized implant (Episealer, Episurf, Stockholm, Sweden) has been proposed to i
