Abstract: A wearable electronic device including: a first portion and a second portion. The first portion includes a first conductive area on a first inner surface of the first portion and a third conductive area on a first outer surface of the first portion. The second portion includes one or more second conductive areas on a second outer surface of the second portion and a fourth conductive area on a second inner surface of the second portion, wherein the first portion is connected to the second portion. A circuit unit is disposed in a second space of the second portion, wherein the circuit unit is configured to enable an input/output unit of the circuit unit in response to the first conductive area and the second conductive areas are triggered.

Abstract: A radiation therapy system may include a magnetic resonance imaging (MRI) device configured to acquire MRI data with respect to a region of interest (ROI). The MRI device may include a main magnet that is around a longitudinal axis and configured to generate a magnetic field. The MRI device may also include a radiation therapy device configured to perform a treatment on at least one portion of the ROI by delivering, based on the MRI data, therapeutic radiation to the at least one portion of the ROI. The radiation therapy device may be rotatable around the longitudinal axis. The MRI device may also include a first shielding structure configured to provide interference shielding for the MRI device or the radiation therapy device. The radiation therapy device may be rotatable relative to the first shielding structure around the longitudinal axis.

Abstract: A sealing element for a ball valve with a first sealing ring and a second sealing ring whose central axes are parallel, the first sealing ring and the second sealing ring being made of different materials, and the first sealing ring being located on a side of the second sealing ring facing towards a ball in a ball valve in an axial direction, and being used to make contact with a spherical surface of the ball to form a seat The first and second sealing rings are fixed together, and the first sealing ring is a stamped annular polytetrafluoroethylene (PTFE) sheet. Since PTFE has a very low friction coefficient, the friction torque between the first sealing ring and the spherical surface of the ball is relatively small, and the first sealing ring does not wear easily and is not prone to sealing failure. A ball valve using the sealing element is also disclosed.

Abstract: The present invention provides methods of identifying a plant containing a lesion in a gene sequence flanked in a wild type chromosome by known polynucleotide sequences. The methods comprise providing a collection of nucleic acids from source plants, providing a data base that associates each nucleic acid with its source plant, amplifying the collection of nucleic acids, thereby detecting the lesion, and using the database to identify the source plant carrying the lesion.

Abstract: The present invention provides nucleic acids that encode bZIP polypeptides that are capable of interacting with NPR1. The present invention also provides for bZIP polypeptides that are capable of interacting with NPR1 as well as transgenic plants comprising a nucleic acids that encode bZIP polypeptides that are capable of interacting with NPR1. Also provided by the present invention is a method for enhancing resistance of plants to pathogens by introducing a recombinant expression cassette comprising a plant promoter operably linked to a polynucleotide sequence encoding a bZIP polypeptide that interacts with NPR1. The present invention also provides for a method of identifying additional bZIP polypeptides that interact with NPR1.
