Differences in forgery attributes of images generated CNN-synthesized and image-editing domains are large, such differences make a unified image detection localization (IFDL) challenging. To this end, we present hierarchical fine-grained formulation for IFDL representation learning. Specifically, first represent manipulated with multiple labels at different levels. Then perform classification these levels using the dependency between them. As result, algorithm is encouraged to learn both...

Painful diabetic neuropathy (PDN) is a common complication in patients with diabetes, and its underlying mechanism remains unclear. Aquaporin-4 (AQP4) plays crucial role removing metabolic waste the glymphatic system. In this study, we aimed to explore relationship between spinal system effect of metformin on PDN. Male Sprague-Dawley rats were randomly allocated into control group ( n = 10), PDN 10). A high-fat high-glucose diet combined low-dose streptozotocin was used induce rats. We...

The photovoltaic/thermal (PV/T) system, as an energy conversion system to generate electricity and heat, has great application potential in northwest zone of ample solar resource China. working media inside the micro heat pipe (MHP) previous studies was acetone. Compared acetone, R141b better stability lower solubility. For fluid MHP, higher Reynolds Number (Re) theoretically means transfer. During typical winter season, when inclination PV panel 45°, average power efficiency (PCE) thermal...

Triclinic α-LiVOPO4 that was prepared at 500°C by citric acid assisted sol-gel technique revealed uniform carbon coating and inter-agglomerate voids/pore-like morphologies from XRD, TG/DTA, SEM, FE-TEM BET studies. When tested for Li-ion insertion properties, α-LiVOPO4/C cathode delivered an initial discharge capacity of 163 mAh/g (98% theoretical value) C/20 rate with impressive retentions until 50 cycles attributed to the combined contributions surface porous structure serve as facile...

The thermal recovery method of steam flooding is one the most common development methods for heavy oil reservoirs. However, after multiple rounds injection development, composition crude and reservoir rock properties have changed greatly, which unfavorable subsequent enhanced recovery. It necessary to study distribution remaining reservoirs, clarify change characteristics components under different conditions. At same time, porosity permeability rocks flooding, its influence on recovery, are...
