The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization
Advanced Energy and Sustainability Research, EarlyView.Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.Mubasshira, Md Mahbubur Rahman, Karib Hassan Khan, Md Nizam Uddin, Dewan Hafiz Nabil +4 morewiley +1 more sourceEddy current losses in transformer windings
, 2020 Målet med denne masteroppgaven er å undersøke en semi-analytisk tapberegningsmetode, spesielt når man tar hensyn til virvelstrømstap i transformatorviklinger. Dette gjøres gjennom sammenligninger mellom simulerte og målte resultater, og gjennom sammenligninger av målte og nominell data fra produsenten.openaire +1 more sourceNeuromorphic Photonic Processing and Memory With Spiking Resonant Tunneling Diode Neurons and Neural Networks
Advanced Intelligent Systems, EarlyView.This work shows resonant tunneling diode‐based opto‐electronic spiking neurons enabling fast edge detection in time series, a two‐layer photonic spiking neural network for complex classification, and a depth‐tunable photonic spiking memory system. Neuromorphic computing—modeled after the functionality and efficiency of biological neural systems—offers ...Dafydd Owen‐Newns, Joshua Robertson, Giovanni Donati, Qusay Al‐Taai, José Figueiredo, Edward Wasige, Kathy Lüdge, Bruno Romeira, Antonio Hurtado +8 morewiley +1 more sourceMicrofluidic Mixing with the Dynamic Control of Magnetic Actuation
Advanced Intelligent Systems, EarlyView.Schematic illustration and flow field visualization of magnetically actuated L‐shaped microrobots displaying cooperative vortex generation for enhanced microscale mixing.

Annals of Neurology, EarlyView.Objective
Amyotrophic lateral sclerosis (ALS) has a very specific neuroimaging signature, but the molecular underpinnings of the strikingly selective anatomic involvement have not elucidated to date. Accordingly, a large neuroimaging study was conducted with 258 participants to evaluate associations between patterns of neurodegeneration and focal ...Marlene Tahedl, We Fong Siah, Efstratios Karavasilis, Jennifer C.

Annals of Neurology, EarlyView.Objective
Plasma biomarkers of Alzheimer's disease (AD) pathology are frequently tested in specialized research settings, which limits the generalizability of findings. Using electronic health records and banked plasma, we evaluated plasma biomarkers—phosphorylated tau 217 (p‐tau217), β‐amyloid 1–42/1–40 (Aβ42/Aβ40) and p‐tau217/Aβ42—in a real‐world ...Katheryn A.Q.

Annals of Neurology, EarlyView.Objective
Dopaminergic imaging is a key biomarker for both the investigation of the biology of Parkinson's disease and related synucleinopathies and the evaluation of potential therapies in clinical trials. This work presents a harmonized approach for quantifying dopaminergic molecular imaging tracers, such as [123I]ioflupane (dopamine transporter scan Zhen Fan, Graham Searle, Gaia Rizzo, Justin Albani, Patrick Cella, Robert Comley, Gregory Klein, Luca Passamonti, Cristian Salinas, Adam J.
