Multifeature Fusion Neural Network for Oceanic Phenomena Detection in SAR Images

open access: yesSensors, 2019
Oceanic phenomena detection in synthetic aperture radar (SAR) images is important in the fields of fishery, military, and oceanography. The traditional detection methods of oceanic phenomena in SAR images are based on handcrafted features and detection ...

SAR Simulations & Safety

open access: yesNeuroImage, 2018
At ultra-high fields, the assessment of radiofrequency (RF) safety presents several new challenges compared to low-field systems. Multi-channel RF transmit coils in combination with parallel transmit techniques produce time-dependent and spatially varying power loss densities in the tissue.

Design of a demestic-producing astronal-level low-voltage pulse power supply

open access: yesDianzi Jishu Yingyong
Synthetic Aperture Radar (SAR) is an active earth observation system that can observe the earth 24/7. Pulse power supply is an important component of SAR operation.

SARS coronavirus

open access: yesUirusu, 2003
SARS is a new type of infectious pneumonia that emerged in China in November 2002. It spread around the world through an outbreak in Hong Kong in March 2003. Patients were reported in 29 countries, and around 800 people died, although a majority of these cases were in Asian countries.

SAR Pancake Ice Thickness Retrieval in the Terra Nova Bay (Antarctica) during the PIPERS Expedition in Winter 2017

open access: yesRemote Sensing, 2019
Pancake and frazil ice represent an important component of the Arctic and Antarctic cryosphere, especially in marginal ice zones. The retrieval of their thickness by remote sensing is, in general, a difficult task.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
