Abstract: The present disclosure is related to the field of polymer processing, and, in particular, to a vinyl-modified nanofiller interfacial compatibilizer and a method for producing a compatibilized polymer blend. Vinyl-modified nanofillers can be used together with an initiator as a compatibilizer for polymer blends. The initiator can initiate a free radical reaction between the chains of the polymers in the blend and the vinyl groups on the surface of the vinyl-modified nanofiller, leading to in situ formation of a co-crosslinked polymer and thus compatibilization of the blend as well as improved tensile strength and modulus thereof. Results of examples showed that vinylsilane grafted onto the surface of the vinyl-modified nanofiller makes it possible for the nanofiller to be used as an effective compatibilizer. The vinyl-modified nanofillers can be used as a compatibilizer for various polymer blends systems.

Abstract: A system and method for measuring a functional lateralization of a subject brain is provided. The method includes providing a set of functional magnetic resonance imaging (fMRI) data acquired during a resting state of a subject, and selecting a plurality of seed voxels associated with locations in hemispheres of a brain of the subject. The method also includes determining a degree of within-hemisphere connectivity for each seed voxel using the fMRI data, determining a degree of cross-hemisphere connectivity for each seed voxel using the fMRI data, and computing an autonomy index for each seed voxel using the degree of within-hemisphere connectivity and the degree of cross-hemisphere connectivity, wherein the autonomy index is indicative of a connectivity asymmetry between the hemispheres. The method further includes generating a report indicative of a specialization profile determined for a region of interest in the brain of the subject.

Abstract: A method for prompting charging position includes acquiring a value of a first charging parameter through a first induction coil of an electronic device, determining whether a prompt message needs to be sent out based on the value of the first charging parameter, and after outputting the prompt message is determined, sending out the prompt message through an output unit of the electronic device to guide a user to move the electronic device to change a relative position between the electronic device and a wireless charging device from a first relative position to a second relative position. Further, the electric power obtained by and converted through the first induction coil when the relative position is the first relative position is smaller than the electric power obtained by and converted through the first induction coil when the relative position is the second relative position.

Abstract: Systems and method for producing functional brain organization maps are provided. The method includes providing functional connectivity magnetic resonance image (fcMRI) data, a population atlas, a variation map indicative of inter-subject variability in the atlas. The method also includes initializing a subject map using the atlas, determining a reference signal for each functional connectivity network in the subject map using signals derived from the fcMRI data, computing correlations between the signals and reference signal of each functional connectivity network, and iteratively updating the subject map by reassigning locations in the subject brain when correlating with a functional connectivity network, updating at each iteration the reference signal using the subject map, the population atlas, the variation map, and the set of fcMRI data. The method further includes generating a report indicative of a functional brain organization for the brain of the subject using the subject map.
