Abstract: A quantitative weed monitoring method guides the selection of weed prevention and control measures, and belongs to the field of plant protection. The method performs rapid and quantitative monitoring of weeds in a farmland in different farming modes in the whole growth period by using a four-level visual observation method in the seedling stage, a sampling method in the growth stage, a seven-level visual observation method in the mature stage, and a soil seed bank survey before planting, and implements a targeted weed control policy according to a quantitative index of the weeds, thereby achieving continuous prevention and control of the weeds. Through continuous monitoring, the occurrence rule and dynamic of the weeds can be determined, the weed prevention and control measures are implemented, and the usage frequency and amount of herbicides are reduced, so that the weed occurrence is controlled, and the planting costs and environmental pollution are reduced.

Abstract: A method, electronic device, and computer-readable medium for displaying a user input. The method includes determining whether a writing utensil is within a predetermined proximity of the display panel while a display panel of the electronic device is powered off. The method also includes, in response to determining that a writing utensil is within the predetermined proximity, activating a black screen display mode for the display panel. Additionally, the method includes, in response to detecting the writing utensil contacting a surface of the electronic device, activating individual pixels corresponding to locations where the writing utensil contacted the electronic device to display a contrasting color.

Abstract: A method for activating an electronic device includes receiving a request to activate the electronic device. The method also includes determining whether activation of the electronic device is permitted according to a device status record associated with the electronic device in a blockchain. In addition, the method includes one of: proceeding with the activation of the electronic device in response to determining that the activation of the electronic device is permitted according to the device status record in the blockchain and blocking the activation of the electronic device in response to determining that the activation of the electronic device is not permitted according to the device status record in the blockchain.

Abstract: Systems and techniques are disclosed for creating segments of users that include baseline users having specified traits and users that are similar to the baseline users. A segment is created by identifying baseline users based on a segment rule that specifies one or more traits of the users to include. The data about the baseline and other users in the dataset is used to extend the segment. A representation of the segment is determined, for example, by determining average values of numeric traits and frequencies of non-numeric trait values of the baseline users in the segment. The representation of the segment is used to determine the similarity (i.e., similarity scores) of users to the segment and ultimately to determine which of the other users, who are not already included in the segment, should be included in the segment based the similarity of their traits to those of the segment representation.

Abstract: Disclosed is a glyphosate-tolerant gene. The nucleotide sequence of the gene is SEQ ID NO: 1, SEQ ID NO: 3 or SEQ ID NO: 5, and a mutant form of the gene that maintains the glyphosate-tolerant activity. The amino acid sequence of a protein encoded by the gene is respectively SEQ ID NO: 2, SEQ ID NO: 4, or SEQ ID NO: 6, and a mutant form of amino acids in a conserved region 1 of positions 280 to 294 and in a conserved region 2 of positions 416 to 433. Also disclosed is the use of the gene and the mutant form thereof in the production of a glyphosate-resistant/tolerant plant.

Abstract: The device is used for locking an access for actuating two switching devices of high-voltage switchgear with the aid of a drive shaft transmitting drive force onto the two switching devices. In order to increase the operational safety of the high-voltage switchgear with little outlay, the locking device comprises a closing disk which is fastened on the drive shaft, a rocker bar arrangement containing at least four rocker bars, and a slider. The slider can be moved, on-site, into two positions, the first of which releases an access for the actuation on-site and blocks an access for the actuation from a remote location, and the second of which blocks the access for the on-site actuation and releases the access for the remote actuation.

Abstract: The present invention is about a method of controlling weeds using the metabolites tenuazonic acid, iso-tenuazonic acid and their salts isolated from the cultures of Alternaria alternata (Fr.) Keissler. The spray of one of these compounds at the rate of 5 to 800 ?g/g can cause the main broad leaf, grassy and sedge weeds to hurt, wilt, even dry to death which exhibits herbicidal activity with broad spectrum, quick killing and efficient effect. The addition of adjuvants improves their herbicidal activity.
