In this short note we observe that within the family of slowly recurrent rational maps on the Riemann sphere, the Collet–Eckmann, second Collet–Eckmann, and topological Collet–Eckmann conditions are equivalent and also invariant under topological conjugacy.

It is well known from Maxwell theory that electromagnetic radiation is emitted whenever electric charges are accelerated in free space. This radiation assumes quite extraordinary properties whenever the charged particles move at ultrarelativistic speed: The radiation becomes very powerful and tightly collimated in space, and it may easily cover a rather wide spectrum ranging from the THz into the

Many allergens are widely used in both consumer and occupational products. In many cases, it is difficult to know all the ingredients of a product since most products are not sufficiently labelled. To diagnose and prevent allergic contact dermatitis, the demonstration of allergens in the products from the patient’s environment is important. Chemical analysis of a product can make it possible to de

An important consequence of protein-lipid interaction is the effect on stability of the protein in solution as well as on its behavior at interfaces. Here we will discuss key aspects of protein aggregation and unfolding as well as the effects of protein structure (random coil proteins versus globular) that are relevant for our understanding protein-lipid interaction. The main types of emulsifiers

Polycyclic aromatic hydrocarbons (PAHs) have endocrine disrupting properties and they cross the placental barrier, but studies on gestational exposure and child anthropometry are inconclusive. We aimed to elucidate the impact of early gestational PAH exposure on anthropometry from birth to 10 years of age in 1295 mother-child pairs from a nested sub-cohort of the MINIMat trial in Bangladesh. Sever

Shuker points to some inconsistencies in my terminology about consequence laws in evolutionary biology, specifically that gene flow and recombination are not as easily classified as one gets the impression of after reading Sober (1984). I agree, and I also emphasize that evolutionary biology should not only focus on consequence laws, but also source laws arising from the ecological selective envir

In this article, we deal with the so-called "risky sexual behaviours" and the spread of HIV/AIDS among the community of MSM (men who have sex with other men). For a long time, both the sociological analysis and the medical and epidemiological approach studied the behaviour of the gay population as “inherently” more problematic in terms of spreading the human immunodeficiency virus. For these studi

OBJECTIVE: To describe the study design of the COPE Staff cohort study on working conditions for maternal and neonatal healthcare workers (MNHCWs), and present baseline data regarding job satisfaction, work-life conflicts, stress, and burnout.METHODS: Between January and April 2021, 957 MNHCWs (administrative and medical staff) completed a baseline survey. Average levels of job satisfaction, work-

Massive MIMO is one of the leading technologies for connecting very large numbers of energy-constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge resides in partitioning the many nodes into groups that can communicate simultaneously such that the mutual interference is minimized. Here we propose node partitioning strategies that do not require full c

PURPOSE: To investigate factors related to omitted total body skin examination (TBSE) in skin cancer diagnostics while managing patients using teledermoscopy (TDS) in Swedish primary care.METHODS: 4,987 TDS referrals from primary care centers were analyzed to identify factors associated with failing to perform TBSE. Data collected included age, gender of patient and physician, and reason for a vis

This article looks at a sample of academic articles in the field of terrorism studies and international relations to explore the ways in which marriage, sexual activity and close relationships in jihadist groups are framed, imagined and investigated. Despite the scarcity of research being conducted on the subject, this article reveals that, in the study of terrorism, the issue of intimate relation

Objective: To identify prognostic factors for patients with advanced persistent, recurrent, or 2nd primary oral cavity squamous cell carcinoma (OCSCC) potentially unsuitable for salvage surgery with free tissue flap (FTF) reconstruction. Materials and methods: A population-based cohort of 83 consecutive patients with advanced OCSCC who underwent salvage surgery with FTF reconstruction at a tertiar

Dynamic glucose enhanced (DGE) chemical exchange saturation transfer (CEST) MRI is an emerging imaging technique that provides a molecular-specific type of image contrast, based on magnetic labelling of exchangeable protons. The technique enables the use of biodegradable sugars as contrast agents, and such compounds are believed to have less side effects than conventional MRI contrast agents.

Most landscapes are comprised of multiple habitat types differing in the biodiversity they contain. This is certainly true for human modified landscapes, which are often a mix of habitats managed with different intensity, semi-natural habitats and even pristine habitats. To understand fundamental questions of how the composition of such landscapes affects biodiversity conservation, and to evaluate
