Abstract: An embodiment composite material for semiconductor package mount applications may include a first component including a tin-silver-copper alloy and a second component including a tin-bismuth alloy or a tin-indium alloy. The composite material may form a reflowed bonding material having a room temperature tensile strength in a range from 80 MPa to 100 MPa when subjected to a reflow process. The reflowed bonding material may include a weight fraction of bismuth that is in a range from approximately 4% to approximately 15%. The reflowed bonding material may an alloy that is solid solution strengthened by a presence of bismuth or indium that is dissolved within the reflowed bonding material or a solid solution phase that includes a minor component of bismuth dissolved within a major component of tin. In some embodiments, the reflowed bonding material may include intermetallic compounds formed as precipitates such as Ag3Sn and/or Cu6Sn5.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for switching a secondary cell to a primary cell. A user equipment (UE) monitors a first radio condition of the UE for beams of a primary cell and a second radio condition for beams of one or more secondary cells configured for the UE in carrier aggregation. The UE transmits a request to configure a candidate beam of at least one candidate secondary cell as a new primary cell in response to the first radio condition not satisfying a first threshold and the second radio condition for the at least one candidate secondary cell satisfying a second threshold. A base station determines to reconfigure at least one secondary cell as the new primary cell. The base station and the UE perform a handover of the UE to the new primary cell.

Abstract: The present invention features interferon-free therapies for the treatment of HCV. Preferably, the treatment is over a shorter duration of treatment, such as no more than 12 weeks. In one aspect, the treatment comprises administering at least two direct acting antiviral agents to a subject with HCV infection, wherein the treatment lasts for 12 weeks and does not include administration of either interferon or ribavirin, and said at least two direct acting antiviral agents comprise (a) Compound 1 or a pharmaceutically acceptable salt thereof and (b) Compound 2 or a pharmaceutically acceptable salt thereof.

Abstract: A supported metallocene catalyst includes a carrier and a metallocene component. The carrier includes an inorganic oxide particle and an alkyl aluminoxane material. The inorganic oxide particle includes at least one inorganic oxide compound selected from the group consisting of an oxide of Group 3A and an oxide of Group 4A. The alkyl aluminoxane material includes an alkyl aluminoxane compound and an alkyl aluminum compound that is present in amount ranging from greater than 0.01 wt % to less than 14 wt % base on 100 wt % of the alkyl aluminoxane material. The metallocene component is supported on the carrier, and includes one of a metallocene compound containing a metal from Group 3B, a metallocene compound containing a metal from Group 4B, and a combination thereof. A method for preparing the supported metallocene catalyst and a method for preparing polyolefin using the supported metallocene catalyst are also disclosed.

Abstract: A discharger structure on earloop facemasks includes at least one opening hole on an earloop facemask covered by a cover. The cover is in a streamline shape and has a passage space for airflow. A check valve is disposed in the opening hole at an inner side of the cover, and the cover further has a discharging hole at an opposite side of the check valve, defining an area within the passage space between the check valve and the discharging hole for airflow. Thereby the check valve is closed by a diaphragm when air pressure within the facemask is negative, and the check valve is opened by the diaphragm when air pressure within the facemask is positive, so as to control airflow through the check valve.

Abstract: A blower includes a housing unit, a fan blade unit, a driving device, a start capacitor, a switch device, and a power source device. The power source device is connected electrically to the switch device. The housing unit includes a driver housing for receiving the driving device, and a fan housing for receiving the fan blade unit. The driver housing includes a mounting recess. The housing unit further includes a cover plate for covering removably the mounting recess. The start capacitor and the switch device are disposed removably within the mounting recess, and are connected electrically to the driving device at the mounting recess.

Abstract: A water activating apparatus includes (a) a plurality of floatable fibrous filter balls, an atomizer, a plurality of bio-chemical ceramic wave energy tubes, a receiving barrel, and a magnetizer, (b) a water softening device, (c) an ultraviolet sterilizing lamp, a porous bio-chemical ceramic wave energy plate, a plurality of magnetized bodies, an multi-layer stainless steel filter net, and a filter barrel, (d) a faucet, (e) a sprayer, (f) a sprayer switch mounted between the faucet and the sprayer, (g) a reverse washing switch, (h) a water flow monitor, (i) a gas/water mixer, a magnet-actuating reciprocating high pressure air pump, and a super-oxygen generating barrel, and (j) a transfer device. Thus, the water is activated efficiently, thereby enhancing the water quality contained in the receiving barrel.

Abstract: A wet process with no heating for continuous transfer pattern printing of a cellulose fabric web or its blends by using a corona-treated plastic film as a pattern carrier web and a dye admixed with a thickening agent containing water-soluble and alcohol-soluble hydroxypropyl cellulose or polyvinyl pyrrolidone as ink.
