Dataset of dust mass accumulation rates for the loess-palaeosol sequences from the Carpathian Basin

In this article, a dataset of age-depth modelling data, sedimentation rates and dust mass accumulation rates (MAR) from four loess-palaeosol sequences from the Carpathian Basin is presented. The dataset is related to the article “Detailed luminescence dating of dust mass accumulation rates over the last two glacial-interglacial cycles from the Irig loess-palaeosol sequence, Carpathian Basin”, publ

Cavity-enhanced field-resolved spectroscopy

Femtosecond enhancement cavities1 are key to applications including high-sensitivity linear2–4 and nonlinear5,6 gas spectroscopy, as well as efficient nonlinear optical frequency conversion7–10. Yet, to date, the broadest simultaneously enhanced bandwidths amount to

An automated work-flow for pinniped surveys : A new tool for monitoring population dynamics

Detecting changes in population trends depends on the accuracy of estimated mean population growth rates and thus the quality of input data. However, monitoring wildlife populations poses economic and logistic challenges especially in complex and remote habitats. Declines in wildlife populations can remain undetected for years unless effective monitoring techniques are developed, guiding appropria

Nordic Media Histories of Propaganda and Persuasion

This open access edited volume shines new light on the history of propaganda and persuasion during the Nordic welfare epoch. A common analytical framework is developed that highlights transnational and transmedial perspectives rather than national or monomedial histories. The return of propaganda in contemporary debate underlines the need to historically contextualize the role and function of pers

Nordic Media Histories of Propaganda and Persuasion : An Introduction

The introduction to the edited collection maps the overarching aims of the book, discusses the time frame and the geographical focus, and situates the book in a media historical research tradition on propaganda and persuasion. A key ambition with this volume is to advance a transnational approach to media history, highlighting how actors and institutions, ideas and practices, have been shaped by t

Germline Mutations in CIDEB and Protection against Liver Disease

BACKGROUND Exome sequencing in hundreds of thousands of persons may enable the identification of rare protein-coding genetic variants associated with protection from human diseases like liver cirrhosis, providing a strategy for the discovery of new therapeutic targets. METHODS We performed a multistage exome sequencing and genetic association analysis to identify genes in which rare protein-coding

Is there a change in myocardial nonlinearity during the cardiac cycle?

The distortion of a sound wave during propagation results in progressive transfer of the energy from fundamental to higher harmonics, and is dependent on the nonlinearity of the medium. We studied if relative changes in acoustical nonlinearity occur in healthy myocardium during the cardiac cycle. Radiofrequency data were acquired from transthoracic echocardiography (2.5 and 3.5 MHz), parasternal l

Predicting Grade group 2 or higher cancer at prostate biopsy by 4Kscore in blood and uCaP microRNA model in urine

Elevated prostate-specific antigen (PSA) levels often lead to unnecessary and possibly harmful transrectal ultrasound guided biopsy, e.g. when the biopsy is negative or contains only low-grade insignificant cancer, unlikely to become symptomatic in the man’s normal lifespan. A model based on four-kallikrein markers in blood (commercialized as 4Kscore) predicts risk of Grade group 2 or higher prost

Vascular function in adults with cyanotic congenital heart disease

Background: Patients with cyanotic congenital heart disease (CCHD) may have a low burden of atherosclerosis. Endothelial dysfunction is an early stage of atherosclerosis and endothelial function is previously studied in smaller CCHD groups with different techniques and variable results. We aimed to examine endothelial function and carotid atherosclerosis in a larger group of CCHD patients. Methods

Plasticity and evolutionary convergence in the locomotor skeleton of greater antillean anolis lizards

Plasticity can put evolution on repeat if development causes species to generate similar morphologies in similar environments. Anolis lizards offer the opportunity to put this role of developmental plasticity to the test. Following colonization of the four Greater Antillean islands, Anolis lizards independently and repeatedly evolved six ecomorphs adapted to manoeuvring different microhabitats. By

Particle morphology and rehydration properties of spray-dried microgels and fractal aggregates with varying fractions of native milk serum proteins

To keep their functional properties, it is crucial that protein aggregates maintain their structure after spray drying and that the powders can be fully rehydrated. In this study, microgels and fractal aggregates were prepared by heating a mixture of milk serum protein concentrate and lactose (40/60; %, w/w) at 85 °C for 15 min by varying the pH. Various fractions of native proteins were added to

Azure-winged magpies’ decisions to share food are contingent on the presence or absence of food for the recipient

Helping others is a key feature of human behavior. However, recent studies render this feature not uniquely human, and describe discoveries of prosocial behavior in non-human primates, other social mammals, and most recently in some bird species. Nevertheless, the cognitive underpinnings of this prosociality; i.e., whether animals take others’ need for help into account, often remain obscured. In

Two Applications of Deep Learning in the Physical Layer of Communication Systems [Lecture Notes]

Deep learning has proven itself to be a powerful tool to develop datadriven signal processing algorithms for challenging engineering problems. By learning the key features and characteristics of the input signals instead of requiring a human to first identify and model them, learned algorithms can beat many human-made algorithms. In particular, deep neural networks are capable of learning the comp

Risks, resilience, and pathways to sustainable aviation : A COVID-19 perspective

This paper discusses the COVID-19 pandemic as an opportunity to reconsider the foundations of the global aviation system. There is much evidence that air transport creates opportunities as well as risks. While the former accrue to businesses and individuals, risks are imposed on society. Pandemics, in which aviation has a role as a vector of pathogen distribution, as well as the sector's contribut

Pharmaceutical lobbying and pandemic stockpiling : A feeling of déjà vu in the Nordic countries and why the sociological perspective is crucial to understand COVID-19

The novel coronavirus SARS-CoV-2 (COVID-19) has spread globally in a short period of time and quickly developed into a pandemic. In connection with its progress, entire cities and countries have been closed down, people are quarantined, and infrastructure and trade have been suspended. As this is a new virus, no vaccine or antiviral drugs are available, but instead non-medical measures such as soc

MicroRNA-340-5p inhibits colon cancer cell migration via targeting of RhoA

Colon cancer is the third most common cancer and a significant cause of cancer-related deaths worldwide. Metastasis is the most insidious aspect of cancer progression. Convincing data suggest that microRNAs (miRs) play a key function in colon cancer biology. We examined the role of miR-340-5p in regulating RhoA expression as well as cell migration and invasion in colon cancer cells. Levels of miR-

Thermal stress analysis at the interface of cathode and electrolyte in solid oxide fuel cells

A benign thermal stress in solid oxide fuel cell is of great importance for its stability and the interfaces between different components suffer from unexpected risks of instability such as electrode delamination and crack due to varying thermal expansion coefficients. Besides, chromium poisoning cathode materials leads to phase changes, which possibly induces thermal stresses at the interface of
