Abstract: A method and an apparatus for executing a data processing task in a cluster mixed deployment scenario and a device are provided. A first electronic device is provided with computing nodes of at least two data engines. A specific implementation of the method includes: in response to a first data engine node receiving a first data processing task, determining a first memory occupancy corresponding to the first data processing task, where the first data engine node is deployed on the first electronic device and belongs to a first data engine; and determining whether to execute the first data processing task based on a second memory occupancy corresponding to another data engine node, where the another data engine node is deployed on the first electronic device and belongs to another data engine other than the first data engine in the at least two data engines.

Abstract: A data processing method based on online analytical processing, an electronic device and a storage medium are provided. The method includes: receiving a data operation request, wherein the data operation request includes a first field; determining a target associated data pair from a set of associated data pairs stored in a row-based manner based on the data operation request, and determining a second field associated with the first field according to the determined target associated data pair; taking a field value corresponding to the second field in a fact table of a first database as a target field value corresponding to the first field, and executing an operation indicated by the data operation request for the target field value; wherein fields belonging to the second data type among the associated data pairs are stored in the fact table.

Abstract: A data reading and writing method, apparatus and electronic device are provided. In one embodiment, the method includes: receiving a data reading and writing request for a first database, wherein the first database stores data in a column-oriented storage format, the data reading and writing request is used for reading/writing data from/into a row storage table, the first database includes a front-end node and a back-end node, the front-end node is used for receiving the data reading and writing request and the back-end node is used for storing data; parsing the data reading and writing request in the front-end node and sending a parsing result to the back-end node; and reading/writing data from/into a second database by using the parsing result in the back-end node, wherein the first database calls data from the second database, and the second database stores data in a row-oriented storage format.

Abstract: An assembly method for a silicon cooling arm that connects a cool source to an aluminum sleeve of a cryogenic target includes a bulb of a strut (2) preset in an arc-shaped groove (5-3) of a rotary table (5). Additionally, a first section (3-1) of a connecting shaft (3) is inserted into a center insertion hole (5-2) of the rotary table (5). A second section of the connecting shaft (3) is attached to an upper surface of a disk body (5-1). A coaxial connector (4) and a strut stop (1) are sheathed on the connecting shaft (3). A recessing (2-2) of the strut (2) is fitted onto a boss (1-2) of the groove in the strut stop (1). Finally, a fifth section (3-5) of the connecting shaft (3) is inserted into a hollow part in a hollow disk body (1-1) of the strut stop (1).

Abstract: Retroreflective sheeting (10) comprising a retroreflecting layer (12), which has an array of retroreflective elements (34) formed thereon, and a divergence-enhancing layer (14) which is positioned in front of the retroreflecting layer (12). The divergence-enhancing layer (14) has localized aberration regions (42) which change the divergence of light traveling therethrough. The placement of the localized aberration regions (42) relative to the retroreflective elements (34) broadens the divergence range of the sheeting (10).

Abstract: A cube corner array with minute modifications of the dihedral angles of some of the cube corners is produced by introducing a stress or change via the opposite side of the substrate. The array having aberrated elements can be replicated for use in the manufacture of a tool, and the tool can be used in the manufacture of retroreflective products of broader divergence.

Abstract: A method of making a microneedle array structure (20) comprising a plurality of simultaneously formed microneedles (24), each microneedle (24) having a protrusion (32) and a passageway (34) extending therethrough. The method comprises the steps of pressing an embossable sheet material between a complimentary tools and radiantly heating the sheet material using radiant energy from a radiant energy source. One tool is relatively-radiantly-transparent, and another tool and/or the sheet material is relatively-radiantly-absorptive.
