Provided is a 10-methoxycamptothecine derivate of formula (1), wherein R is selected from hydrogen, C1-6 alkyl, C1-6 haloalkyl, aryl substituted C1-6 alkyl, phosphate substituted C1-6 alkyl, amino-substituted C1-6 alkyl, carboxyl substituted C1-6 alkyl, hydroxyl substituted C1-6 alkyl, and amide- substituted C1-6 alkyl; R1 is selected from hydrogen and t-butoxycarbonyl substituted amino. Also provided in the present invention are the preparation method of the derivate and the use thereof in anti-tumor drug preparation.
摘要:
Heart valve operation is assessed with patient-specific medical diagnostic imaging data. To deal with the complex motion of the passive valve tissue, a hierarchal model is used. Rigid global motion of the overall valve, non-rigid local motion of landmarks of the valve, and surface motion of the valve are modeled sequentially. For the non-rigid local motion, a spectral trajectory approach is used in the model to determine location and motion of the landmarks more efficiently than detection and tracking. Given efficiencies in processing, more than one valve may be modeled at a same time. A graphic overlay representing the valve in four dimensions and/or quantities may be provided during an imaging session. One or more of these features may be used in combination or independently.

摘要:
A method and system for fusion of multi-modal volumetric images is disclosed. A first image acquired using a first imaging modality is received. A second image acquired using a second imaging modality is received. A model and of a target anatomical structure and a transformation are jointly estimated from the first and second images. The model represents a model of the target anatomical structure in the first image and the transformation projects a model of the target anatomical structure in the second image to the model in the first image. The first and second images can be fused based on estimated transformation.
摘要:
The present invention relates to a power converter with extremely low standby power consumption. The power converter comprises a rectification module having at least one unilateral switch which has a control terminal, an anode terminal and a cathode terminal. The control terminal is coupled to a control signal, wherein when the control signal issues a first level, the channel between the anode terminal and the cathode terminal is enabled to act as a unilateral switch; and when the control signal issues a second level, the channel between the anode terminal and the cathode terminal is open circuited.
摘要:
An integrated messaging system for performing various types of messaging across different types of networks, including integrated user interfaces and administrator interfaces. Embodiments include a communication server that couples among networks of different types, and an interface module that couples to the communication server. The interface module may be hosted on a messaging server of a network. The interface module pulls various user information from the messaging server, including information relevant to at least the network that includes the messaging server. A cache couples to the communication server and to the interface module to hold information from the communication server and/or the user information pulled from messaging server. The interface module directs a message from the messaging server and/or the cache to at least one device on the networks using the user information.
摘要:
An apparatus for detecting change in orientation comprises a first position sensor and a second position sensor. The position sensors are in different orientations. The outputs of the position sensors are filtered to smooth out instantaneous and/or insignificant changes in orientation, or noise. A processor or logic circuitry is configured to determine a change in both outputs, and communicate such a change. Furthermore, the processor or logic circuitry is configured to electrically and/or physically de-couple batteries from a power delivery system in an EV.
摘要:
A method of registering a plurality of Battery-Monitoring-Units (BMUs) in a battery pack with a Battery-Management-System (BMS), the method comprising: providing an indication to a user, wherein the indication prompts the user to register one of the BMUs with the BMS; the user performing an action on a communication-initiating mechanism on one of the BMUs, wherein the communication-initiating mechanism is configured to initiate the sending of a communication by the BMU to the BMS in response to the user performing the action; the BMU sending a communication to the BMS in response to the user performing the action on the communication-initiating mechanism; the BMS receiving the communication from the BMU; and the BMS registering the BMU in response to receiving the communication from the BMU.
