A Novel Protein‐Polysaccharide Oral Nanoemulsion Targeting Activated Hepatic Stellate Cells to Enhance the Therapeutic Effect of Pirfenidone on Fibrosis After Transarterial Chemoembolization for Liver Cancer

Advanced Functional Materials, EarlyView.
Transarterial Chemoembolization (TACE) may aggravate liver fibrosis. In this study, a novel oral targeting nanoemulsion is fabricated to enhance the therapeutic effect of antifibrotic drug‐pirfenidone (PFD) on fibrosis after TACE. Studies have shown that PFD nanoemulsion can enhance the oral liver targeting effect of PFD, and effectively improve the ...

Improving Co-registration for Sentinel-1 SAR and Sentinel-2 Optical images [PDF]

arXiv, 2020
Co-registering the Sentinel-1 SAR and Sentinel-2 optical data of European Space Agency (ESA) is of great importance for many remote sensing applications. However, we find that there are evident misregistration shifts between the Sentinel-1 SAR and Sentinel-2 optical images that are directly downloaded from the official website.

Bioresorbable and Wireless Rechargeable Implanted Na‐ion Battery for Temporary Medical Devices

Advanced Functional Materials, EarlyView.
An all‐solid‐state bioresorbable Na‐ion battery is developed, composed entirely of bio‐eliminable materials. In vivo and ex vivo tests confirmed harmless disintegration of this implanted battery. Lifetime of the implanted battery can be precisely controlled by adjusting the dissolvable encapsulation layer's thickness.

Deep Recurrent Neural Networks for mapping winter vegetation quality coverage via multi-temporal SAR Sentinel-1 [PDF]

arXiv, 2017
Mapping winter vegetation quality coverage is a challenge problem of remote sensing. This is due to the cloud coverage in winter period, leading to use radar rather than optical images. The objective of this paper is to provide a better understanding of the capabilities of radar Sentinel-1 and deep learning concerning about mapping winter vegetation ...

A speckle filter for Sentinel-1 SAR Ground Range Detected data based on Residual Convolutional Neural Networks [PDF]

arXiv, 2021
In recent years, machine learning (ML) algorithms have become widespread in all the fields of remote sensing (RS) and earth observation (EO). This has allowed the rapid development of new procedures to solve problems affecting these sectors. In this context, this work aims at presenting a novel method for filtering speckle noise from Sentinel-1 ground ...
