Initiative Defense against Facial Manipulation [PDF]

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 35(2), 1619-1627, 2021, 2021
Benefiting from the development of generative adversarial networks (GAN), facial manipulation has achieved significant progress in both academia and industry recently. It inspires an increasing number of entertainment applications but also incurs severe threats to individual privacy and even political security meanwhile.

Morphological Analysis Reveals a Compartmentalized Duct in the Venom Apparatus of the Wasp Spider (Argiope bruennichi)

open access: yesToxins, 2021
Spiders are one of the most successful groups of venomous animals, but surprisingly few species have been examined in sufficient detail to determine the structure of their venom systems.

Evaluation of GS‐omega/kappa‐Hxtx‐Hv1a and Bt toxins against Bt‐resistant and ‐susceptible strains of Helicoverpa zea (Boddie) and Spodoptera frugiperda (J.E. Smith)

open access: yesPest Management Science, EarlyView.
The addition of 10 μg cm−2 of Cry1Ac to the surface of GS‐omega/kappa‐Hxtx‐Hv1a (ω/κ‐Hv1a) incorporated diet can significantly increase the mortality of Cry‐resistant Helicoverpa zea compared to diets without the Cry1Ac toxin. Abstract BACKGROUND Helicoverpa zea and Spodoptera frugiperda are destructive insect pests of cotton and corn.

Giant Surface Plasmon Induced Drag Effect (SPIDEr) in Metal Nanowires [PDF]

open access: yes, 2009
Here, for the first time we predict a giant surface plasmon-induced drag effect (SPIDEr), which exists under conditions of the extreme nanoplasmonic confinement. Under realistic conditions, in nanowires, this giant SPIDEr generates rectified THz potential differences up to 10 V and extremely strong electric fields up to 10^5-10^6 V/cm. The SPIDEr is an

The Gold‐Maker of Animal Oil and Prussian Blue Fame — The Chemical and Medicinal Science Philosophy of Johann Conrad Dippel

open access: yesThe Chemical Record, EarlyView.
The radical Pietist Johann Conrad Dippel was a self‐proclaimed adept – a maker of gold and the philosophers’ stone. He was also a magister of theology, a doctor of medicine, and a self‐taught chemist, who coinvented the pigment Prussian Blue together with Johann von Diesbach, became known for his animal pyrolysis oil, his wonder‐wound balm, his ...

Recent enrichment of megafauna in the north of Eurasia supports the concept of Pleistocene rewilding

open access: yesWildlife Biology, EarlyView.
‘Pleistocene rewilding' refers to the concept of restoring ecosystems to their state during the Pleistocene epoch, by (re‐)introducing species or their close relatives that were present during that time, in an effort to revive ecological processes that existed before human‐driven extinctions.
