Ultrasensitive ¹²⁹Xe Magnetic Resonance Imaging: From Clinical Monitoring to Molecular Sensing. [PDF]

Adv Sci (Weinh)
Ultrasensitive 129Xe magnetic resonance imaging (MRI) is a novel clinically approved technology that overcomes the sensitivity limitations of traditional 1H MRI by introducing hyperpolarized 129Xe as the signal source. This review summarizes recent advancements in 129Xe MRI, covering its principles, methodologies, applications ranging from clinical ...

Uncertain effectiveness of Miscanthus bioenergy expansion for climate change mitigation explored using land surface, agronomic and integrated assessment models

GCB Bioenergy, Volume 15, Issue 3, Page 303-318, March 2023., 2023
This study compares yields and soil carbon impacts of meeting future bioenergy demand with large‐scale plantation of Miscanthus, using three different types of global model. The dedicated crop model (MiscanFor) shows high yields in Europe but poor performance in the tropics, with an increase in soil carbon with cultivation.

How Is Time Distributed in a River Meander Belt?

Geophysical Research Letters, Volume 50, Issue 2, 28 January 2023., 2023
Abstract River meandering controls the age of floodplains through its characteristic paces of growth and eventual cutoff of channel bends, forming oxbows. Hence, floodplain‐age distributions should reflect a river's characteristic size and migration rate.

Grass‐to‐stone surface inspired long‐term inhibiting scaling

Nano Select, Volume 3, Issue 11, Page 1509-1525, November 2022., 2022
In the dynamic scaling condition, “Nano‐grass” like low surface tension molecules with –C–Si groups come out from the self‐cleaning coating surface at 80°C, and spontaneously migrate onto high surface tension CaCO3 surface by surface tension and capillary force, and form a “micro‐leaf” like hydrophobic self‐healing film, which is a process of self ...

In Situ Monitoring and Numerical Experiments on Vertical Deformation Profiles of Large‐Scale Underground Caverns in Giant Hydropower Stations

Geofluids, Volume 2021, Issue 1, 2021., 2021
Spatial response is a feature of rock deformation in regions surrounding large‐scale underground caverns and includes significant vertical components due to the construction method of layered excavation. This vertical response is different to the longitudinal response of excavation deformation surrounding shallow tunnels.

Modelling Cochlear Mechanics

BioMed Research International, Volume 2014, Issue 1, 2014., 2014
The cochlea plays a crucial role in mammal hearing. The basic function of the cochlea is to map sounds of different frequencies onto corresponding characteristic positions on the basilar membrane (BM). Sounds enter the fluid‐filled cochlea and cause deflection of the BM due to pressure differences between the cochlear fluid chambers.

Subharmonic Resonance of Van Der Pol Oscillator with Fractional‐Order Derivative

Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014
The subharmonic resonance of van der Pol (VDP) oscillator with fractional‐order derivative is studied by the averaging method. At first, the first‐order approximate solutions are obtained by the averaging method. Then the definitions of equivalent linear damping coefficient (ELDC) and equivalent linear stiffness coefficient (ELSC) for subharmonic ...

Perceived quality of BRDF models

Computer Graphics Forum, Volume 44, Issue 4, July 2025.
Abstract Material appearance is commonly modeled with the Bidirectional Reflectance Distribution Functions (BRDFs), which need to trade accuracy for complexity and storage cost. To investigate the current practices of BRDF modeling, we collect the first high dynamic range stereoscopic video dataset that captures the perceived quality degradation with ...
