The unfolding of the COVID-19 pandemic has been very difficult to predict using mathematical models for infectious diseases. While it has been demonstrated that variations in susceptibility have a damping effect on key quantities such as the incidence peak, the herd-immunity threshold and the final size of the pandemic, this complex phenomenon is almost impossible to measure or quantify, and it re
We took a two-tiered approach to test monophyly of Nelsonioideae and place the group within Lamiales, and to determine relationships among taxa within the group. Phylogenetic analysis of a molecular dataset (ndhF + trnL-F) for a broad sample of Lamiales supports monophyly of Nelsonioideae and places the clade with strong support as sister to a lineage composed of all other plants treated as Acanth
Tuberculosis (TB) is among diseases of global health importance with Sub Saharan Africa (SSA) accounting for 25% of the global TB burden. TB prevalence among miners in SSA is estimated at 3,000-7,000/100,000, which is about 3 to 10-times higher than in the general population. The study's objective was to determine the prevalence of TB and associated risk factors among mining communities in Mereran
In recent years, since the cloud can provide tremendous advantages regarding storage and computing resources, the industry has been motivated to move industrial control systems to the cloud. However, the cloud also introduces significant security challenges since moving control systems to the cloud can enable attackers to infiltrate the system and establish an attack that can lead to damages and d
In the process of shape transformation of metal nanoparticles (MNPs) embedded in dielectrics resulting from swift heavy-ion irradiation, key parameters such as the energy deposition threshold, the necessity of a molten track and the NP size have been identified for amorphous silicon dioxide. The extension of such parameters to other dielectrics is yet unclear. We present experimental evidence of t
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
Establishing an empathic clinical relationship is a cornerstone of high-quality palliative care. More than simply approaching patients with a pleasant affect or "being nice,"we propose that skilled clinicians routinely employ distinct psychological elements when creating effective bonds with seriously ill patients and their families. Palliative care involvement has been shown to improve a variety
This letter presents a radio frequency front-end (RFFE) for 5G new radio (NR) receivers operating in frequency range 1 (FR1). The core of this RFFE is a synthetic fourth-order Q -enhanced RF filter employing gm -boosting, noise-canceling, capacitive cross-coupling, and forward body-biasing techniques to achieve 1.7 to 6.4 GHz operating range and 1% to 40% adjustable fractional bandwidth (FBW). The
Invasive alien species threaten biodiversity with domestic gardens acting as a major pathway for the introduction of alien species. Even though the Nordic region is not currently a hotspot for biological invasions, the number of invasions in the Nordic area has been predicted to increase due to climate change. Given a time lag between introduction and invasion, many non-invasive horticultural alie
Quantitative magnetic resonance imaging (MRI) techniques have been developed as imaging biomarkers, aiming to improve the specificity of MRI to underlying pathology compared to conventional weighted MRI. For assessing the integrity of white matter (WM), myelin, in particular, several techniques have been proposed and investigated individually. However, comparisons between these methods are lacking
Off-specular X-ray reflectivity measurements were carried out to follow the in situ development of surfactant-templated silica thin films at the air-water interface under conditions of controlled relative humidity and temperature, using an enclosed sample cell designed for this purpose. The results suggest a strong dependence of formation time and growth mechanism on ambient conditions. Thin films
We are working towards a mixed reality-based human-robot collaboration interface using gaze and gesture as methods of communicating intent in a search and rescue scenario to optimize the operation. The lack of mature algorithms and control schemes for autonomous systems makes it still difficult for them to operate safely in high-risk environments. We are approaching the problem through symbiosis w
This contribution aims to elucidate some problematic aspects of the financial tools (such as the Conditionality Regulation, Recovery and Resilience Facility and other measures), used by the EU to ensure compliance with the rule of law. It draws attention to certain legal conundrums which challenge the functional effectiveness of these tools both within the Union (the internal dimension) and in the
All patients in a randomized study comparing chemotherapy with chemotherapy plus radiotherapy for patients with astrocytomas grade 3 and 4, were considered for reoperation when tumour progression was established. Fifty-eight patients were reoperated and 85 were not. Different prognostic factors, such as age, sex, Karnofsky performance status and reoperation were evaluated univariately and simultan
To date, studies investigating maternal postpartum depression (PPD) have mainly focused on identifying failures in interactions of postpartum depressed mothers and their infants, often attributed to single dysfunctional maternal behaviors. Intrusiveness has been identified as a dysfunctional behavior characterizing mothers suffering from PPD. However, this research does not consider the co-constru
The consecutive binding of two potassium ions to a bis(18-crown-6) analogue of Tröger’s base (BCETB) in water was studied by isothermal titration calorimetry using four different salts, KCl, KI, KSCN, and K2SO4. A counterintuitive result was observed: the enthalpy change associated with the binding of the second ion is more negative than that of the first (ΔH°bind,2 < ΔH°bind,1). This remarkable f
European infrastructure managers (IMs) create annual timetables for trains that will run during a year. Freight trains in Sweden often deviate from this by being added, cancelled, delayed or early, resulting in increased costs for IMs and railway undertakings (RUs). We investigate the frequency of and causes for these deviations, using one year of operational data for 48,000 trains, and 15 stakeho
