The Feasibility Test of Electric Propulsion Systems: Case Study for a Light and Fixed‐Wing Aircraft

Energy Science &Engineering, EarlyView.
ABSTRACT This study investigates the feasibility and performance of a fully electric propulsion system (EPS) integrated into a light fixed‐wing aircraft. The system consists of a 65 kW‐class electric motor, a high‐efficiency inverter, and dual lithium‐ion battery packs with a total capacity of 27 kWh—collectively engineered to fulfill both power ...

Detailed structural analysis of lipids directly on tissue specimens using a MALDI-SpiralTOF-Reflectron TOF mass spectrometer. [PDF]

PLoS ONE, 2012
Direct tissue analysis using a novel tandem time-of-flight (TOF-TOF) mass spectrometer is described. This system consists of a matrix-assisted laser desorption/ionization ion source, a spiral ion trajectory TOF mass spectrometer "SpiralTOF (STOF)", a ...

Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats

Remote Sensing in Ecology and Conservation, EarlyView.
Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (

Correlative X‐ray imaging and fluorescence microscopy in hydrated environments

Journal of Synchrotron Radiation, EarlyView.
We present a combined imaging platform that integrates beamline‐compatible fluorescence microscopy with scanning small‐angle X‐ray scattering to enable sequential multimodal investigations of hydrated cells under near‐native conditions. We apply our method to ordered cytoskeletal structures in different cell types and demonstrate the direct correlation

Working‐Class Muscles? Co‐Operative Gyms in Interwar Britain

History, EarlyView.
Abstract The Health & Strength League's network of co‐operative gymnasiums constituted one of interwar Britain's most significant yet overlooked physical culture institutions, affiliating over 800 gyms across Britain and Ireland by 1939. Drawing on Health & Strength magazine's editorial content and reader contributions, this article argues that these ...

Evaluating the Suitability of Perfusion-Based PD Probes for Use in Altered Gravity Environments

Biosensors
Measurable changes in electrophysiology have been documented in spaceflight, creating a pathway for disease genesis and progression in astronauts. These electrophysiology changes can be measured using potential difference (PD).

PARTY‐STATE URBANISM: Coevolution of Local State Capacity and Strategic Alliances in Shenzhen

International Journal of Urban and Regional Research, EarlyView.
Abstract What is distinct about Chinese urban governance? Classic theories predict that when the central state retreats from resource allocation, capacity‐strained local governments must form alliances with non‐state actors, thereby diluting state power. In China, however, state power remains dominant despite decentralization.

Orthostatic intolerance and motion sickness after parabolic flight [PDF]

Journal of Applied Physiology, 2001
Because it is not clear that the induction of orthostatic intolerance in returning astronauts always requires prolonged exposure to microgravity, we investigated orthostatic tolerance and autonomic cardiovascular function in 16 healthy subjects before and after the brief micro- and hypergravity of parabolic flight.
