Abstract: A power amplifier (PA) linearization technique with a wider linearized power range is proposed. Proposed two types of linearizers with cross-coupled PMOS and NMOS configuration. The idea is to use a complimentary device compared with the PA core device, and the behavior of Cgs of the linearizer are also complimentary to the PA itself. In the other words, the overall Cgs of the PA with the linearizer would be constant without leading to non-linear waveform. Both linearizers can effectively compensate not only AMAM but also AMPM. First type of linearizer can be integrated with PA cores, and second type of linearizer can be used in the IMN. Both linearizers have effective IM3 reduction in different corner.

Abstract: A pliers includes a first body with an engaging groove and a second body with an elongated slot pivotally connected with each other. The elongated slot includes a left and right positioning grooves and a protruding portion disposed therebetween. A tap button is pivotally connected to the second body. A supporting member is disposed between the second body and the tap button. When the first body comes close to the second body, the tap button can be tapped to a first position and engaged in the engaging groove. Thus, the first body is blocked and cannot pivot relative to the second body. The tap button can be tapped to a second position and detached from the engaging groove. Thus, the first body is pivotable relative to the second body. A positioning block is extending from the tap button and can be engaged in any of the positioning grooves for positioning the tap button.

Abstract: A method for processing image data and a system thereof are provided. The method is operated in the system including an encoding system and a decoding system. In the decoding system, multiple image data packages are received from the encoding system. The image data packages include multiple encoded data that are formed by encoding the pixels of an image and the pixels are beforehand rearranged according to an arrangement order.

The decoding circuits start to decode the encoded data from an initial code synchronously for enhancing decoding performance. The method can be applied to decoding of high resolution images. The image is reproduced after the decoding process.

Abstract: The invention provides an isolated recombinant oncolytic vaccinia virus, pharmaceutical compositions and uses thereof for drugs for treatment of tumors and/or cancers. The isolated recombinant oncolytic vaccinia virus is functionally deficient in the TK gene and the VGF gene, and the genome of the recombinant oncolytic vaccinia virus is integrated with an exogenous IL-21 gene, and wherein the IL-21 gene is capable of being expressed in tumor cells. The recombinant oncolytic vaccinia virus can selectively replicate in tumor cells, and can also fully exert the anti-tumor immune effect of the exogenous IL-21, such that the oncolytic killing effect of the oncolytic virus and the anti-tumor immune stimulation effect of IL-21 achieve a synergic effect.

Abstract: The present disclosure provides an isolated recombinant oncolytic adenovirus, a pharmaceutical composition, and uses thereof for drugs for treatment of tumors and/or cancers. The recombinant oncolytic adenovirus is a selectively replicating oncolytic adenovirus, and the genome of the recombinant oncolytic adenovirus is integrated with a coding sequence of exogenous shRNA capable of inhibiting PDL1 expression in tumor cells. The replication capability of the virus in normal primary cells is much lower than the replication capability of the virus in tumor cells. Moreover, the expressed shPDL1 can significantly reduce the level of PDL1 protein highly expressed in tumor cells. Thus, the oncolytic killing effect of the oncolytic virus and the anti-tumor immunostimulatory effect of immune cells produce a synergistic effect.

Abstract: A pliers has guiding surfaces at tooth portions of the first pliers body and tooth portions of the engaging unit of the control member. Therefore, when the pressing block of the control member is not pressed, even if the first pliers body is engaged with the tooth portions of the engaging unit, the second pliers body can still be pushed forward relative to the first pliers body, so that the second guiding surfaces of the second tooth portions of the engaging unit slide relative to the first guiding surfaces of the first tooth portions and each of the first tooth portions is moved to engage with a next corresponding second tooth portion, thereby allowing the second pliers portion being movable toward the first pliers portion. Hence, the clamping distance of the pliers can be adjusted to match with an object to be clamped.
