Training-Free Location-Aware Text-to-Image Synthesis
Current large-scale generative models have impressive efficiency in
generating high-quality images based on text prompts. However, they lack the
ability to precisely control the size and position of objects in the generated
image. In this study, we analyze the generative mechanism of the stable
diffusion model and propose a new interactive generation paradigm that allows
users to specify the position of generated objects without additional training.
Moreover, we propose an object detection-based evaluation metric to assess the
control capability of location aware generation task. Our experimental results
show that our method outperforms state-of-the-art methods on both control
capacity and image quality
Bis[1-benzyl-3-(quinolin-8-ylmethÂyl)-2,3-dihydro-1H-imidazol-2-yl]dibromidoÂpalladium(II) acetonitrile disolvate
In the title compound, [PdBr2(C20H17N3)2]·2CH3CN, the Pd atom, which lies on an inversion center, is four-coordinated in a square-planar geometry. The two imidazole rings are coplanar and nearly perpendicular to the plane formed by Pd, the coordinated imidazole C atom and one of the Br atoms, making a dihedral angle of 75.1 (2)°
Incorporating social objectives in evaluating sustainable fisheries harvest strategy
Fisheries management must take account of environmental sustainability, economic profitability, and social benefits generated by the public resources. The traditional approach of maximum economic yield (MEY), however, is yet to consider social objectives in deriving quantitative quotes. Current MEY evaluation framework would be appropriate if the economic rent was distributed back to the public. If public resources are privatized as corporations, the rent largely flows to the owners of large capital in the fishing industry. This is in stark contrast to the aims of benefiting the community as a whole. In this short paper, we promote a socially responsible framework in decision-making of fisheries management. This approach is beyond the fleet-based MEY approach, for it incorporates fleet profitability, chain profitability, employment, environmental concerns, and broad social benefits, in strict accordance with stock sustainability. Recognizing the needs of fishers, as well as the interests of chain sectors and the broader community, is a vital part of ensuring responsible fishery management and a viable future for Australian fisheries. The established framework will provide open view scenarios and enrich the MEY approaches in fisheries management
Wettability Alteration of Sandstone by Chemical Treatments
Liquid condensation in the reservoir near a wellbore may kill gas production in gas-condensate reservoirs when pressure drops lower than the dew point. It is clear from investigations reported in the literature that gas production could be improved by altering the rock wettability from liquid-wetness to gas-wetness. In this paper, three different fluorosurfactants FG1105, FC911, and FG40 were evaluated for altering the wettability of sandstone rocks from liquid-wetting to gas-wetting using contact angle measurement. The results showed that FG40 provided the best wettability alteration effect with a concentration of 0.3% and FC911 at the concentration of 0.3%
