Abstract: Embodiments of this application provide a middle frame, a battery cover, and an electronic device. The electronic device may include a mobile or fixed terminal with an edge frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Two types of materials: ceramics and plastic, are used to form a middle frame and a battery cover, thereby reducing a weight of the electronic device. This resolves a problem that is of a relatively large weight of an existing electronic device and that is caused when a pure ceramic middle frame and a pure ceramic battery cover are used in the electronic device.

Abstract: Embodiments of this application provide a middle frame, a rear cover, and fabrication methods thereof, and an electronic device. The electronic device may include a mobile or fixed terminal with a frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS terminal, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Ceramics and fiber reinforced composite are used to form frames of a rear cover and a middle frame, to reduce thicknesses of a ceramic outer housing and a ceramic outer frame, thereby reducing a weight of the electronic device.

Abstract: An antenna apparatus and a terminal, where the antenna apparatus includes an antenna body and at least one stub, where a feed terminal is disposed on the antenna body, one end of the stub is electrically coupled to a coupling point between the feed terminal and a first open-circuit end of the antenna body, and the other end of the stub is an open-circuit end, and an antenna body length between the coupling point and the feed terminal is a half of a wavelength corresponding to a specified operating frequency, and a length of the stub is one quarter of the wavelength corresponding to the specified operating frequency.

Abstract: An enclosure of a mobile terminal and a sputter coating apparatus for making the same are provided. The enclosure includes a substrate and a composite film layer coated onto the substrate. The composite film layer has a thickness changing along a first direction. A difference in thickness between any two regions arranged along the first direction of the composite film layer is less than or equal to 350 nanometers. The enclosure has a spatially varying color corresponding to a wavelength between 400 nanometers and 760 nanometers.

Abstract: Described herein are polyclonal and monoclonal antibodies that binds to VSIG3, compounds that modulate the interaction of VISTA and VSIG3, and methods of making and using the polyclonal and monoclonal antibodies and compounds. Also described herein are methods that include modulating the interaction of VISTA and VSIG3 by introducing a compound that modulates the interaction of VISTA and SIG3.

Abstract: The ligand for VISTA is identified (VSIG3) as well as the use of this ligand and receptor interaction in the identification or synthesis of a VSIG3 agonist or antagonist compounds, preferably antibodies, polypeptides and fusion proteins which agonize or antagonize the effects of VSIG3 and/or VISTA and/or the VSIG3/VISTA interaction. These antagonists may be used to suppress VSIG/3/VISTA's suppressive effects on T cell immunity, and more particularly used in the treatment of cancer, or infectious disease. These agonist compounds may be used to potentiate or enhance VSIG3/VISTA's suppressive effects on T cell immunity and thereby suppress T cell immunity, such as in the treatment of autoimmunity, allergy or inflammatory conditions. Screening assays for identifying these agonists and antagonist compounds are also provided.
