Abstract: The invention relates to a tension clamp for the holding of a rail for rail vehicles and a rail fastening point. The tension clamp has a central section having two legs, two torsional sections connected thereto and leading away laterally in an outwards direction having a supporting zone, and two supporting arms connected to the torsional sections. The supporting arms run to the front face of the tension clamp and have a spring section and a support section with a supporting zone. The fact that the support sections point laterally in an outwards direction such that the straight lines which in each case connect the centers of the supporting zones and the torsional section allocated to the supporting arm in an area on the rear face of the tension element increases the natural frequencies of the tension clamp such that they are outside of stimulation frequencies that occur in practice.

Abstract: The invention relates to a sleeper for the track superstructure, which is manufactured in one piece from a plastic material, with the sleeper having an elongated base shape with two end sections, which are connected by a middle section of the sleeper and held at a distance and on their upper side in each case one contact surface is provided for in each case one rail to be supported on the respective end section with a reinforcement extending in the longitudinal direction of the sleeper being embedded into the middle section.

Abstract: A transportation device for fruit and vegetable picking in a solar greenhouse is provided, which may include a guide rail, a moving mechanism and a picking box. The guide rail is horizontally fixed on side surfaces of multiple supporting columns in the solar greenhouse, an upper side and a lower side of the guide rail are respectively provided with horizontally extended sliding grooves, and a top of the moving mechanism is slidably connected to the guide rail through the sliding grooves, and the picking box is hung at a bottom of the moving mechanism. The transportation device is used to hang the picking box at a bottom of the moving mechanism, so that the moving mechanism can carry the picking box to move along the sliding grooves to transport the picking box to a destination, thereby saving time, saving labor and reducing a labor cost.

Abstract: Embodiments of the present disclosure relate to adaptive RFID communication. A tag device includes a storage configured to store content that is executable by a proxy device associated with a reader device. The tag device includes a communication component configured to transmit the content to the reader device, the content, when executed by the proxy device, causing an action associated with the tag device to be performed.

Abstract: A method for processing a memory page in memory, where the memory page in the memory includes an idle single-level cell (SLC) memory page, an active SLC memory page, an inactive SLC memory page, and a multi-level cell (MLC) memory page, and when a quantity of idle SLC memory pages of any virtual machine (VM) is less than a specified threshold, the processing method includes converting one idle SLC memory page to two MLC memory pages, copying data in two inactive SLC memory pages to the two converted MLC memory pages, and releasing storage space of the two inactive SLC memory pages to obtain two idle SLC memory pages.

Abstract: Provided are genes, coding proteins and uses thereof, gene elements, genes and uses, gene elements, methods for synthesizing odd numbered medium chain aliphatic aldehydes, for synthesizing odd numbered medium chain aliphatic alcohol and for synthesizing even numbered medium chain aliphatic hydrocarbons. Provided is method for producing odd numbered aliphatic alcohols in Escherichia coli. An ?-dioxygenase from rice is used without additional deoxidization and energy supply from cells. The ?-dioxygenase can also be used for synthesizing aliphatic alcohols with different proportions of C11 to C15 by co-working with different thioesterases.

Abstract: A process running method and apparatus is disclosed. The method is: selecting a code page from a candidate process, storing only a code page of the candidate process into a swap partition, and releasing memory space occupied by the code page; updating a physical address that is of the code page and that is stored into a page entry; and when it is determined that the candidate process to which the code page belongs needs to be run, if the code page needs to be executed, directly executing the code page in the swap partition.
