Abstract: The present invention provides a medium-carbon boron-containing steel. The chemical components of the medium-carbon boron-containing steel are as follows in mass percentage: 0.37-0.45% of C; 0.17-0.37% of Si; 0.60-0.90% of Mn; 0.020-0.060% of Al; 0.0008-0.0035% of B; 0.030-0.060% of Ti; P?0.025%; S?0.025%; Cr?0.25%; Ni?0.20%; Mo?0.10%; Cu?0.20%; and the remainder is Fe and inevitable impurities. The controlled rolling and controlled cooling method suitable for the on-line normalizing treatment of medium-carbon boron-containing steel sequentially comprises the following steps: heating, rough rolling, finishing rolling, cooling by passing through water, and cold bed slow cooling. The medium-carbon boron-containing steel can meet the requirements of having a hardness of 190-220 HBW, an actual grain size that is ?7 grade, and a banded structure that is ?2 grade.

Abstract: A CTLA-4 small molecule degradation agent and an application thereof. The CTLA-4 small molecule degradation agent comprises a compound having the structure represented by formula I or a pharmaceutically acceptable salt, an ester, a deuterated product, an isomer, a solvate, a prodrug, or an isotopic label thereof: a new class of small molecule compounds having high degradation activity on CTLA-4. The compounds show a good degradation activity on CTLA-4 at the nanomolar (nM) level in in vitro studies.

Abstract: A printing device (100, 200) may include a carriage (101, 201) to hold an integrated printhead (103, 203) in the printing device; a manifold latch (105, 205) to connect the integrated printhead and an ink tank connector in a locked position; and a controller (109, 209) to align the carriage within the printing device based on a level of health of the integrated printhead and a latching position of the manifold latch. Furthermore, a non-transitory computer readable medium and a printing method are disclosed.

Abstract: An improved MiniPCI connector structure includes a mini area bus connector and a set of plate type antenna connector. The bus connector comprises an upper unit and a lower unit buckling to each other. The upper unit has a plurality of contacting terminals within, and the adjacent sides of contacting terminals protrude out of the opening of the upper unit to form adapting slot and plug; the flange of the upper unit has two buckling portions, and the lower unit has corresponding adapting slot and corresponding buckling portion corresponding to the contacting terminals and the buckling portions at the flange of the upper unit. Thus, the interne card can be adapted into the adapting slot of the upper unit and the buckling of the buckling portion and the corresponding buckling portion enables the upper unit joining with the lower unit as a mini area bus connector and a set of plate type antenna connector positioning on the circuit board.

Abstract: An exemplary method for dynamically presenting a directory tree is disclosed. The method comprises the steps of: providing a database for storing a default directory tree having a plurality of nodes, contents of each node, and logical regulations among the nodes; reading the contents of each node, and putting the contents into each node of the default directory tree; dragging a node from a source address to a destination address; determining whether logical relations between the dragged node and the other nodes accord with the logical regulations; generating a rearranged directory tree if the logical relation between the dragged node and the other nodes accord with the logical regulations, and for putting the contents into corresponding nodes of the rearranged directory tree. A related system is also disclosed.

Abstract: A system for editing contract clauses in static web pages is provided. The system includes a database and a web server. The web server includes: a contract reading module for reading a contract in a static web page on the web server; a clause writing module for writing a selected clause to be edited into the database; a clause editing module for providing an edit textbox to edit the selected clause; and an updating module for updating database and the contract in the static web page after editing. A related method is also provided.
