摘要:
A method for implementing roam restriction and a system thereof are disclosed in the present invention, by setting up a list of areas where the terminal is allowed to roam. The method includes: the terminal sends a wireless service request to the mobile switching center on the wireless communication network side, wherein the request carries the information of at least one cell currently activated by this terminal; the mobile switching center determines whether there is a cell among the at least one cell currently activated by this terminal, whose cell information is included in the list of areas where the terminal is allowed to roam, if yes, executes current wireless service for this terminal; otherwise, rejects to execute current wireless service for this terminal. With this method, when the number of the cells is increased or changed, there is no need to modify the relationship between the associated IMSI/MIN and the cells or modify the IMSI/MIN of the terminals one by one under the circumstance of migration. Furthermore, since the information of all cells currently activated by the terminal is obtained by the wireless communication network side, when the terminal is located in an overlapped area covered by two cells, this method for implementing roam restriction on the terminal can still be used.

摘要:
Systems and methods are provided for imaging using complex lasers. In general, a complex laser may be used as an electromagnetic source for an imaging application. The use of a lower spatial coherence configured complex laser in imaging applications may advantageously mitigate coherent artifacts in imaging such as cross-talk and speckle and improve overall image quality. Imaging applications where a complex laser may be useful include both incoherent imaging applications, such as digital light projectors and traditional microscopy, and coherent imaging applications, such as optical coherence tomography (OCT) and holography. The systems and methods provided also enable controlling the degree of spatial coherence of a complex laser.

The present invention discloses compounds of Formula (I), and pharmaceutically acceptable salts, esters, or prodrugs thereof: Q-G-A-L-B—W (I), which inhibit RNA-containing virus, particularly the hepatitis C virus (HCV). Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.
摘要:
In a shimming method for an irregular object to be examined by magnetic resonant equipment magnetic field parameters are measured at measurement points located on the surface of an irregular object to be examined. Based on the measured magnetic field parameters, the positions and number of shims for adjusting magnetic field homogeneity are calculated when a passive shimming is to be performed, or the current value in a shimming coil are calculated when an active shimming is to be performed, or at the same time both the positions and number of shims and current value in the shimming coil are calculated when active shimming and passive shimming are to be performed at the same time. Shimming is then performed according to the calculated results. These above steps are repeated until achieving required magnetic field homogeneity. Since the homogeneous region is designed to have an irregular shape, it can provide a better coverage of the irregular object to be examined, and at the same time it reduces the shimming constraints to the unnecessary regions outside the irregular object to be examined, therefore avoiding shimming in those unnecessary regions.
