  • Publication number: 20240121685
    Abstract: A method of reducing gray energy consumption and achieving optimal gray energy saving for carbon neutralization is proposed. In a cellular network, each cell or BS (group of cells) has renewable (green) and non-renewable (gray, on-grid power) energy sources. The renewable (green) energy is highly variable and unpredictable, while non-renewable (gray, on-grid power) is stable but is not renewable and thus has more carbon impact. Each cell or BS (group of cells) services is associated UEs when it is on. In one novel aspect, a cell or BS (group of cells) that consumes more non-renewable energy can give some or all of its served UEs to another cell or BS (group of cells) that consumes less non-renewable energy.

The semiconductor device has a first dielectric wall between an n-type source/drain region and a p-type source/drain region to physically and electrically isolate the n-type source/drain region and the p-type source/drain region from each other. A second dielectric wall is formed between a first channel region connected to the n-type source/drain region and a second channel region connected to the p-type source/drain region. A contact is formed to physically and electrically connect the n-type source/drain region with the p-type source/drain region, wherein the contact extends over the first dielectric wall. The first electric wall has a gradually decreasing width W5 towards a tip of the dielectric wall from a top contact position between the first dielectric wall and either the n-type source/drain region or the p-type source/drain region.

    Abstract: The present invention discloses a dual-targeting drug carrier and a method for fabricating the same, wherein WGA- and FA-modified MPEG-PLA nanoparticles of the carrier enable the anticancer drugs encapsulated thereinside to pass through BBB and target human glioblastoma cells. The dual-target drug carrier is fabricated in an emulsion-solvent evaporation technology and verified with an in-vitro BBB model formed of HBMECs, HAs and HBVPs. The present invention can increase the permeability of the in-vitro BBB model to the dual-target drug carrier and promote the glioblastoma-inhibition effect. Therefore, the present invention would contribute to the clinical therapy of brain cancers substantially in the future.
