Abstract: The present invention provides a supporting hook structure, comprising a sleeve, a fixing rod, a first limit unit, a hook and a fixing device. The fixing rod is connected to the side surface of the sleeve. The hook body is connected to one end of the sleeve. The first limit unit is arranged on the side surface of the sleeve and adjacent to the hook body. The first limit unit makes the hook body rotates with the axis direction of the sleeve as a rotation axis. The fixing device is connected to the other end of the sleeve to fix the rotating position of the hook body. Through the above, the hook part enters the proximal thigh from a surgical entrance and the hook part rotates to make the hook part abut against the proximal femur to complete the positioning and fixation of the femur hook structure to the femur.

Abstract: A valve for a pneumatic system, has: a first enclosure defining a first chamber and a first connection port; a second enclosure defining a second chamber and a second connection port; a first shell subjected to a first pressure differential and movable from a default position to a reversed position via snap-through buckling upon the first pressure differential reaching a threshold; and a second shell having a shape different than a shape of the first shell, the second shell resiliently movable from an initial position to a deformed position when subjected to a second pressure differential, wherein a first flow rate of a fluid via the first connection port induces deformation of the second shell followed by a snapping of the first shell thereby generating a second flow rate greater than the first flow rate.

Abstract: A method of independently changing a melt rheology property value of a bimodal polyethylene polymer being made using a bimodal catalyst system in a single gas phase polymerization reactor. The method comprises process conditions comprising alkane(s) in the reactor. The method comprises a bimodal catalyst system that is characterized by an inverse response to alkane(s) concentration. The method comprises changing concentration of the alkane(s) in the reactor by an amount sufficient to effect a measurable change in the melt rheology property value; wherein the bimodal catalyst system is characterized by an inverse response to alkane(s) concentration such that when the alkane(s) concentration is increased, the melt rheology property value of the resulting bimodal polyethylene polymer is decreased, and when the alkane(s) concentration is decreased, the melt rheology property value of the resulting bimodal polyethylene polymer is increased.

Abstract: The subject application relates to a server, terminal and non-transitory computer-readable medium. The server for handling streaming data for a live streaming, comprising one or a plurality of processors, wherein the one or plurality of processors execute a machine-readable instruction to perform: recording the streaming data for the live streaming; storing the streaming data as archive contents with first identifier; receiving interaction information during the live streaming; storing the interaction information as contexts with second identifier, transmitting the archive contents with first identifier to a first user terminal; and transmitting the contexts to the first user terminal according to the first identifier and the second identifier. According to the subject application, the archive contents may be more immersive and the user experience may be enhanced.

Abstract: Aspects described herein include devices and methods with chain routing of signals for massive antenna arrays. In some aspects, an apparatus is provided that includes a first millimeter wave (mmW) transceiver having a first port, a second port, one or more antenna elements, a plurality of chain mmW transceiver ports, and switching circuitry.
