Salinity Gradient Power - Reverse Electrodialysis (SGP-RED) is a promising membrane-based technology to harvest the energy of mixing from solutions of different ionic concentration. Unfortunately, currently available commercial ion exchange membranes – being not specifically designed for RED – are far from satisfying the requirements of this operation, especially when operated with hyper-concentra

The properties of atomic negative ions are to a large extent determined by electron-electron correlation which makes them an ideal testing ground for atomic many-body physics. In this paper, we present a detailed experimental and theoretical study of excited states in the negative ion of iridium. The ions were stored at cryogenic temperatures using the double electrostatic ion ring experiment faci

Within-plant variation in seed size may merely reflect developmental instability, or it may be adaptive in facilitating diversifying bet-hedging, that is, production of phenotypically diverse offspring when future environments are unpredictable. To test the latter hypothesis, we analyzed patterns of variation in seed size in 11 populations of the perennial vine Dalechampia scandens grown in a comm

Objective Behaviour therapy (BT) for Tourette's disorder (TD) and persistent (chronic) motor or vocal tic disorder (PTD) is rarely available. We evaluated the feasibility of adapting two existing BT protocols for TD/PTD (habit reversal training (HRT) and exposure and response prevention (ERP)) into a therapist-guided and parent-guided online self-help format. Design A pilot, single-blind, parallel

Gartland type III fracture is the most troublesome type of supracondylar humerus fracture. These injuries most often occur in school age children, but they are seen in pediatric patients of all ages. The goal of this study was to analyze toddlers with Gartland type III fractures to identify clinically significant differences compared with older children. A retrospective cohort study was conducted

Parkinson’s Disease (PD) is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons in the Substantia nigra pars compacta (SNpc). Apoptosis is thought to play a critical role in the progression of PD, and thus understanding the effects of antiapoptotic strategies is crucial for developing potential therapies. In this study, we developed a unique genetic model to

Quantum technologies and experiments often require preparing systems in low-temperature states. Here we investigate cooling schemes using feedback protocols modeled with a quantum Fokker-Planck master equation (QFPME) recently derived by Annby-Andersson et al. [Phys. Rev. Lett. 129, 050401 (2022)0031-900710.1103/PhysRevLett.129.050401]. This equation describes systems under continuous weak measure

An Fe(III)-NHC complex has been employed for the green light driven catalysis of base-promoted homolytic aromatic substitution (BHAS) reactions. Tributylamine was used as a sacrificial electron donor, together with potassium carbonate as base in dimethyl sulfoxide as solvent. In contrast to previously studied photocatalysts, the excited Fe(III)-NHC complex is not reducing the arylhalide substrates

Att färdas i mörker: insekters lösningar, vinster och kostnaderIn sin ständiga jakt på mat måste många insekter undvika att krocka med grenar, stenar och blad, samt färdas i en lämplig kompassriktning. Åtskilliga insekter använder sin syn för att kontrollera detta. En nektarsökande humla, till exempel, reglerar sin flyghastighet efter hur snabbt föremål i omgivningen rör sig över dess ögon. Denna Flying, as well as walking insects rely on vision to regulate locomotion, even in the dark when the visual system is much less reliable. To manage visual control of these behaviours at low light intensities, many insects have evolved optical adaptations, such as larger facet lenses and wider rhabdoms, and neural adaptations, such as spatial and temporal summation, to increase their visual sensitiv

In sandy beach systems, the aeolian sediment transport can be governed by the vertical structure of the sediment layers at the bed surface. Here, data collected with a newly developed sand scraper is presented to determine high-resolution vertical grain size variability and how it is affected by marine and aeolian processes. Sediment samples at up to 2 mm vertical resolution down to 50 mm depth we

Transition metal dichalcogenide (TMDCs) monolayers make an excellent component in optoelectronic devices such as photodetectors and phototransistors. Selenide-based TMDCs, specifically molybdenum diselenide (MoSe2) monolayers with low defect densities, show much faster photoresponses compared to their sulfide counterpart. However, the typically low absorption of the atomically thin MoSe2 monolayer

Empathy is our ability to experience and understand the mental states of others. In movement perception, and in particular in dance spectatorship, it has been argued that we experience observed movements through our own bodies: kinesthetic empathy. However, it has been unclear what exactly kinesthetic empathy encompasses on an experiential level as dance spectatorship research has been dominated b

I denna uppsats studerar vi en matematisk modell av vattenvågor över djupt vatten. I synnerhet studerar vi vågor som färdas med konstant hastighet i en horisontell riktning och är likformiga i den vinkelräta horisontella riktningen. På grund av den matematiska svårigheten med den allmänna modellen är det vanligt att utgå från förenklade versioner av problemet. I denna uppsats, gör vi antaganden omIn a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touchin

Sodium ion batteries have been considered as promising alternatives to lithium ion batteries for large-scale renewable energy and smart grids applications due to their low cost and rich resources. However, critical drawbacks such as low energy density and poor stability are hindering their development and application. In this work, a stable symmetric sodium ion cell using sodium vanadium pyrophosp

This paper studies cone-preserving linear discrete-time switched systems whose switching is governed by an automaton. For this general system class, we present performance analysis conditions for a broadly usable performance measure. In doing so, we generalize several known results for performance and stability analysis for switched and positive switched systems, providing a unifying perspective.
