Abstract: The present disclosure relates to polymers which contain a hydrophobic and hydrophilic segment which is sensitive to pH. In some aspects, the polymers form a micelle which is sensitive to pH and results in a change in fluorescence based upon the particular pH. In some aspects, the disclosure also provides methods of using the polymers for the imaging of cellular or extracellular environment or delivering a drug.

Abstract: Provided are a porous silicone resin and a light-weight flexible flame-retardant composite material, belonging to the technical field of nano-porous materials. The porous silicon resin is prepared from a porous silicon resin precursor solution by means of curing and drying processes. The porous silicone resin precursor solution includes a flame retardant, a surfactant, a siloxane monomer, a catalyst, an auxiliary agent and a solvent. The porous silicone resin precursor solution is obtained by firstly dissolving the flame retardant and the surfactant in the solvent, and then adding the siloxane monomer, the catalyst and the auxiliary agent and mixing them uniformly. The porous silicone resin and the light-weight flexible flame-retardant composite material prepared therefrom have the excellent properties of high porosity, high flame retardancy, high elasticity and high strain.

Abstract: A method of crowdsourcing annotation for medical image data based on image comparison, includes developing an annotation task; acquiring and verifying medical images according to requirements of the annotation task, and performing statistics on the medical images that meet verification standards to obtain an amount of image data acquired; archiving the medical images that meet the verification standards to form a medical image database; setting up annotation rules, and generating annotation schemes and annotation samples according to the requirements of the annotation task and annotation rules; distributing the medical images in the medical image database to multiple crowdsourcing annotation sides, so that each medical image being annotated by the multiple crowdsourcing annotation sides; annotating, by the crowdsourcing annotation sides, the distributed medical images according to the annotation schemes and the annotation examples to form the annotated images; and merging multiple annotated images correspondi

Abstract: One disclosed method involves detecting a request to download a file, via a network, to a first storage medium associated with a client device, and determining that the file is potentially sensitive. The method further involves initiating a process to download the file to a second storage medium rather than the first storage medium based at least in part on the file being potentially sensitive.

Abstract: Disclosed are compounds and methods for preventing or treating necroinflammation associated with ferroptotic processes. The method includes inhibiting 15 lipoxygenase/phosphatidylethanolamine binding protein (15LOX/PEBP1) complex, wherein the inhibitor exhibits a higher binding affinity or binding activity for 15LOX/PEBP1 complex compared to 15LOX alone. Necroinflammation associated with ferroptotic processes causes several pathogenic conditions including upper or lower respiratory disorders, acute or chronic brain injury, renal injury, injury by radiation, neurodegenerative disorder, among others. The disclosed compounds and methods are useful in subjects diagnosed with one or more of these conditions.
