Natural regeneration after anthropogenic disturbance is slow in the tundra biome, but assisted regeneration can help speed up this process. A tracked off-road vehicle damaged a High Arctic dwarf shrub heath in Svalbard in May 2009, drastically reducing the vegetation cover, soil seed banks, and incoming seed rain. We assisted regeneration the following year using six different revegetation treatments ...

Agglomeration of charged ice and dust particles in the mesosphere and lower thermosphere is studied using a classical electrostatic approach, which is extended to capture the induced polarisation of surface charge. Collision outcomes are predicted whilst varying the particle size, charge, dielectric constant, relative kinetic energy, collision geometry and the coefficient of restitution. In ...

Background<p> <p>There is a substantial gap in our knowledge about family correlates of child emotional and behavioral problems in low- and middle-income countries (LMIC). The present study contributes to filling this gap by examining such correlates in a larger population study in Nepal.<p> Methods<p> <p>Our study is a cross-sectional, observational study among 3840 Nepali children aged 6–18 ...

LTX-315 is a nonameric oncolytic peptide in early clinical development for the treatment of solid malignancies. Preclinical and clinical evidence indicates that the anticancer properties of LTX-315 originate not only from its ability to selectively kill cancer cells, but also from its capacity to promote tumortargeting immune responses. Here, we investigated the therapeutic activity and immunological ...

Analyzing unusual events is significantly important for video surveillance to ensure people safety. These events are characterized by irregular patterns that do not conform to the expected behavior in the surveillance scenes. We present a novel irregularity-aware semi-supervised deep learning model (IA-SSLM) for detection of unusual events. While most existing works depend on the availability ...

Standardised management of tuberculosis may soon be replaced by individualised, precision medicineguided therapies informed with knowledge provided by the field of systems biology. Systems biology is a rapidly expanding field of computational and mathematical analysis and modelling of complex biological systems that can provide insights into mechanisms underlying tuberculosis, identify novel ...

The global pandemic has forced academics to engage in remote doctoral supervision, and the need to understand this activity is greater than ever before. This contribution involved a cross-field review on remote supervision pertinent in the context of a global pandemic. We have utilised the results of an earlier study bringing a supervision model into a pandemic-perspective integrating studies ...

Enhanced ion line spectra as a response to magnetic field-aligned high frequency (HF) pumping of the overdense polar ionosphere with left-handed circular polarization, can be observed at the top and bottomside F-region ionosphere under certain conditions. The European Incoherent Scatter (EISCAT) UHF radar was directed in magnetic zenith on October 18th and 19th, 2017 while stepping the pump ...

<ol> <li>Free-living parasite life stages may contribute substantially to ecosystem biomass and thus represent a significant source of energy flow when consumed by non-host organisms. However, ambient temperature and the predator's own infection status may modulate consumption rates towards parasite prey.</li> <li>We investigated the combined effects of temperature and predator infection status ...

<p<i>Background:</i> Public health, primary healthcare, and nursing are founding principles of public health nursing. Thus, the underpinning curriculum needs to reflect these core principles. Public health nursing educators sought to delve deeper into curricula and training of public health nurse (PHNs)in Ireland and Norway. <p><i>Objective:</i> To compare PHNs’ educational training in Ireland and ...
