Abstract: Disclosed are a catalyst component and a catalyst for olefin polymerization, and an olefin polymerization method. The catalyst component comprises magnesium, titanium, a halogen and an internal electron donor, wherein the internal electron donor comprises a monocarboxylic acid ester compound and a diether compound, and the molar ratio of the monocarboxylic acid ester compound to the diether compound is (0.0035-0.7):1. By using the catalyst, a polymer having both a high isotactic index and a high melt flow index can be prepared.

Abstract: Please replace the abstract originally filed with the following: A display panel and a display device. Because the pixel distribution density in a second display subarea (A12) is lower than that in a first display subarea (A11), the quantities of sub-pixels (pix) connected to scanning lines are not completely the same; a sub-pixel row having the greatest quantity of sub-pixels (pix) in the display panel is taken as a reference sub-pixel row, the quantity of the sub-pixels (pix) of the reference sub-pixel row is taken as a reference value, a sub-pixel row having the quantity of sub-pixels (pix) smaller than the reference value is taken as a compensation sub-pixel row, and a scanning line connected to the compensation sub-pixel row is taken as a first scanning line; the display panel is provided with load compensation units corresponding to at least part of the first scanning lines, and the load compensation units are located in the second display subarea.

Abstract: A dental resin composite comprising a thermally cured composition of polymeric resin monomers and inorganic fillers that comprise at least 80 wt % total filler loading is provided. Mill blocks made from the dental resin composite and produced via free radical polymerization under high-temperature (approximately 160° C. to 220° C.) and high-pressure process (approximately 300 MPa to 560 MPa) exhibited enhanced mechanical strength and good esthetics suitable for use in CAD/CAM indirect restorations such as, inlays, onlays, crowns and bridges.

Abstract: A photo-curable resin composition is suitable for the fabrication of 3D printed objects via digital light processing (DLP) or stereolithography (SLA). The photo-curable resin composition can provide 3D printed objects having lower volumetric shrinkage, high accuracy and favorable mechanical strength for dental application such as building models, implant templates, surgical guides, night guard/occlusal splints, dentures, clear aligners, and temporary restorations.

Abstract: Two-part dual-curing dental compositions containing a hydroperoxide, a thiourea derivative and an acetylacetonate salt as redox radical initiator system, are provided. The dental compositions may contain an acidic monomer for use as a self-adhesive cement. The dental compositions possess enhanced shelf-life stability for working/setting time, bonding strength, color stability, slump, flexural strength/modulus, and when kept at 50° C. for more than 16 weeks.

Abstract: A method for manufacturing a semiconductor device includes providing a semiconductor substrate, forming a plurality of integrated circuit (IC) devices on the semiconductor substrate, and forming a seal ring structure surrounding each of the IC devices. Forming the seal ring structure includes forming a plurality of interlayer dielectric layers on the semiconductor substrate, and forming a plurality of hollow through-hole structures within each of the interlayer dielectric layers.

Abstract: A method, apparatus, and scheduling system for managing a mix of time-critical messages and general messages. Messages, which are referenced by message identifiers stored in a transmission queue buffer, are scheduled for transmission using a schedule configuration table. The schedule configuration table defines an order for processing a mix of time-critical messages and general messages. The messages are scheduled according to the characteristics for time-critical messages and general messages defined in columns of configuration tables and status tables. The messages that have been scheduled are transmitted from an end system in which the time-critical messages are prioritized during transmission over the general messages.

Abstract: A semiconductor device includes a semiconductor substrate, a plurality of integrated circuit devices on the semiconductor substrate, and a seal ring structure surrounding each one of the integrated circuit devices. The seal ring structure includes a plurality of interlayer dielectric layers and a plurality of hollow through-hole structures disposed within each of the interlayer dielectric layers. Each of the hollow through-hole structure within an interlayer dielectric layer includes a through-hole disposed within one of the interlayer dielectric layers, a diffusion barrier layer formed at the bottom, sidewalls and the top of the through-hole, and a seed layer disposed on the diffusion barrier layer. The diffusion barrier layer and the seed layer cover the top of the through-hole so that the through-hole has a void to form the hollow through-hole structure.
