Abstract: A method for transferring a virtual object between maps, executed by a source logic server, is provided and includes, when the virtual object enters a target sub-map from the current sub-map in a map and a determination frame centering on the virtual object is overlapped with the target sub-map, transmitting a map cutting request to a scheduling server, a projection area of the determination frame in the map being greater than a projection area of the virtual object in the map, and the scheduling server being connected to at least two logic servers; determining a target logic server from the at least two logic servers according to an object resource transferring notice returned by the scheduling server; and copying a resource of the virtual object to the target logic server, and after the copying is completed, destroying the resource of the virtual object.

Abstract: A control process of inclusions in ultra-clean rare earth steel, wherein the content of rare earth elements REM in the ultra-clean rare earth steel, the total oxygen content T[O]m, the total sulfur content T[S]m in the steel, and the total oxygen content T[O]r in a rare earth metal or alloy added to the steel are controlled to satisfy the following formula: ?500<REM?(m*T[O]m+n*T[O]r+k*T[S]m)<?30, where REM is the content of rare earth elements in the steel, in ppm; T[O]m is the total oxygen content in the steel, in ppm; T[O]r is the total oxygen content in a rare earth metal or alloy added to the steel, in ppm; T[S]m is the total sulfur content in the steel, in ppm; m is a first correction coefficient, with a value of 2-4.5;n is a second correction coefficient; and k is a third correction coefficient.

Abstract: Provided in the present application are a rare-earth microalloyed steel and a control process. The steel has a special microstructure, and the microstructure comprises a rare earth-rich nanocluster having a diameter of 1-50 nm. The nanocluster has the same crystal structure type as a matrix. The rare earth-rich nanocluster inhibits the segregation of the elements S, P and As on a grain boundary, and obviously improves the fatigue life of the steel. In addition, a rare-earth solid solution also directly affects a phase change dynamics process so that the diffusion-type phase change starting temperature in the steel changes at least to 2° C., and even changes to 40-60° C. in some kinds of steel, thereby greatly improving the mechanical properties thereof, and providing a foundation for the development of more kinds of high-performance steel.

Abstract: An acetabular cup prosthesis comprises an outer cup (1) and a liner (2), in which an inner surface of the outer cup (1) is provided with an abutting face (11) in a circumferential direction thereof; an outer surface of the liner (2) is provided with a protruding snap ring (21) at a bearing part, and is provided with an elastic locking tongue (22) at a non-bearing part; and the protruding snap ring (21) and the elastic locking tongue (22) both abut against the abutting face (11), such that the liner (2) is self-locked in the outer cup (1).

Abstract: Provided are an ultra-clean rare earth steel and an occluded foreign substance modification control method, the steel includes 10-200 ppm of rare earth elements, 50% or more occluded foreign substances in the steel are dispersed into RE-oxygen-sulfide with the average equivalent diameter Dmean ranging from 1-5 ?m in a spherical shape or a substantially spherical shape or a granular shape; according to the method, at least 80%, preferably at least 90%, of Al2O3 occluded foreign substances in the steel are modified into RE-oxygen-sulfide, compared with steel with the same components without rare earth, the total amount of the occluded foreign substances in the steel is reduced by 18% or higher, the cracking probability caused by occluded foreign substances such as Al2O3 in traditional pure steel is reduced, the mechanical performance such as the fatigue life of the steel is remarkably improved.

Abstract: A data analytics platform system includes a first database including economic forecast, house pricing, unemployment, and interest rate data object structures. A second database includes data object structures associated with attributes of mortgage loans and borrowers. A first module performs projections for predicting a monthly status on performing and modified performing mortgage loans. A second module performs projections of lifetime outcomes for delinquent mortgage loans. A third module performs calculations of mortgage loan level credit losses and timing parameters of loan loss recognition attributes. A fourth module performs calculations of forecasted mortgage loan performance attributes, mortgage loan contract terms, and interest rates to generate mortgage loan level cash flow data analytics. A fifth module summarizes projections of data performance analytics over a forecasted period of time, and creates an electronic summary report of the projections.
