Impact of Matrix Surface Area on Griseofulvin Release from Extrudates Prepared via Nanoextrusion

open access: yesPharmaceutics, 2021
We aimed to examine the impact of milling of extrudates prepared via nanoextrusion and the resulting matrix surface area of the particles on griseofulvin (GF, a model poorly soluble drug) release during in vitro dissolution. Wet-milled GF nanosuspensions

A GF-3 SAR Image Dataset of Road Segmentation

open access: yesInformation Technology and Control, 2021
We constructed a GF-3 SAR image dataset based on road segmentation to boost the development of GF-3 synthetic aperture radar (SAR) image road segmentation technology and make GF-3 SAR images be applied to practice better. We selected 23 scenes of GF-3 SAR images in Shaanxi, China, cut them into road chips with 512 × 512 pixels, and then labeled the ...

Wind speed retrieval from the Gaofen-3 synthetic aperture radar for VV- and HH-polarization using a re-tuned algorithm

open access: yesEuropean Journal of Remote Sensing, 2021
In this study, a re-tuned algorithm based on the geophysical model function (GMF) C-SARMOD2 is proposed to retrieve wind speed from Synthetic Aperture Radar (SAR) imagery collected by the Chinese C-band Gaofen-3 (GF-3) SAR.

Parabolic Systems: The GF(3) Case [PDF]

open access: yesTransactions of the American Mathematical Society, 1993
A parabolic system over \(GF(q)\), \(q = p^ f\), is a system of finite groups \(X_ 1,\dots, X_ n\) generating a group \(G\) such that (i) \(X_ i\) contains a Sylow \(p\)-subgroup of each \(X_ i\) (ii) \(O^{p'}(X_ i/O_ p(X_ i))\) is a rank one Lie group in characteristic \(p\) (iii) \(O^{p'}(\langle X_ i,X_ j\rangle / O_ p(\langle X_ i,X_ j\rangle))\), \
