Exact Solution for the Critical State in Thin Superconductor Strips with Field Dependent or Anisotropic Pinning

An exact analytical solution is given for the critical state problem in long thin superconductor strips in a perpendicular magnetic field, when the critical current density j_c(B) depends on the local induction B according to a simple three-parameter model. This model describes both isotropic superconductors with this j_c(B) dependence, but also superconductors with anisotropic pinning described by a dependence j_c(theta) where theta is the tilt angle of the flux lines away from the normal to the specimen plane

Modern temporal network theory: A colloquium

The power of any kind of network approach lies in the ability to simplify a complex system so that one can better understand its function as a whole. Sometimes it is beneficial, however, to include more information than in a simple graph of only nodes and links. Adding information about times of interactions can make predictions and mechanistic understanding more accurate. The drawback, however, is that there are not so many methods available, partly because temporal networks is a relatively young field, partly because it more difficult to develop such methods compared to for static networks. In this colloquium, we review the methods to analyze and model temporal networks and processes taking place on them, focusing mainly on the last three years. This includes the spreading of infectious disease, opinions, rumors, in social networks; information packets in computer networks; various types of signaling in biology, and more. We also discuss future directions.Comment: Final accepted versio

Effectiveness and toxicity of hypofractionated high-dose intensity-modulated radiotherapy versus 2- and 3-dimensional radiotherapy in incurable head and neck cancer

BACKGROUND: This retrospective study evaluates efficacy and tolerability of high-dose hypofractionated radiotherapy (RT) in patients with head and neck cancer. METHODS: All patients with head and neck cancer treated between September 2003 and September 2013 with 12 x 4 Gy RT were included. Two and 3D-RT or intensity-modulated radiotherapy (IMRT) were used. Overall survival (OS), tumor response, and palliative effect were evaluated. RESULTS: Palliative effect occurred in 63% of 81 included patients, lasted a median of 4.6 months, and was correlated with tumor response (p = .006). Median OS was 7.2 months. Confluent mucositis occurred more often in patients treated with 2D/3D-RT than IMRT (26% vs 44%; p = .04) and lasted for a median of 2 weeks. CONCLUSION: High-dose hypofractionated RT resulted in meaningful palliation in 63%, lasting for almost 5 months. IMRT should be the technique of choice, as it results in less high-grade toxicity. The 12 x 4 schedule should be opted for patients with reasonable functional capacities and a life expectancy of >6 months. (c) 2015 Wiley Periodicals, Inc. Head Neck 38: E1264-E1270, 2016

Significant Impact of Coronavirus Disease 2019 (COVID-19) on Human Immunodeficiency Virus (HIV) Care in Hospitals Affecting the First Pillar of the HIV Care Continuum

During COVID-19 lockdown, the in-hospital number of HIV indicator conditions decreased disproportionally compared with other non-COVID-19 diseases, which was accompanied by reduced HIV testing rates, number and proportion of positive HIV tests, and new HIV referrals, with more late presentation after lockdown cessation, indicating a significantly impacted HIV care continuum

Atmosphere–vegetation–soil interactions in a climate change context; impact of changing conditions on engineered transport infrastructure slopes in Europe

In assessing the impact of climate change on infrastructure, it is essential to consider the interactions between the atmosphere, vegetation and the near-surface soil. This paper presents an overview of these processes, focusing on recent advances from the literature and those made by members of COST Action TU1202 – Impacts of climate change on engineered slopes for infrastructure. Climate- and vegetation-driven processes (suction generation, erosion, desiccation cracking, freeze–thaw effects) are expected to change in incidence and severity, which will affect the stability of new and existing infrastructure slopes. This paper identifies the climate- and vegetation-driven processes that are of greatest concern, the suite of known unknowns that require further research, and lists key aspect that should be considered for the design of engineered transport infrastructure slopes in the context of climate change
