An economic, direct synthetic method for producing water soluble ZnS QDs that are ready for bioconjugation is provided. The method can produce aqueous ZnS QDs with emission wavelengths varying from 400 nm to 700 nm. Highly luminescent metal sulfide (MS) QDs are produced via an aqueous synthesis route. MS QDs are capped with thiol-containing charged molecules in a single step. The resultant MS QDs exhibit the distinctive excitonic photoluminescence desired of QDs and can be fabricated to avoid undesirable broadband emissions at higher wavelengths. The aqueous ZnS QDs are stable in biological fluids over a long period of time. In addition, non-toxic ZnS QDs have been produced with good photoluminescence properties.

Computerized interpretation of medical images for quantitative analysis of multi-modality breast images including analysis of FFDM, 2D/3D ultrasound, MRI, or other breast imaging methods. Real-time characterization of tumors and background tissue, and calculation of image-based biomarkers is provided for breast cancer detection, diagnosis, prognosis, risk assessment, and therapy response. Analysis includes lesion segmentation, and extraction of relevant characteristics (textural/morphological/kinetic features) from lesion-based or voxel-based analyses. Combinations of characteristics in several classification tasks using artificial intelligence is provided. Output in terms of 1D, 2D or 3D distributions in which an unknown case is identified relative to calculations on known or unlabeled cases, which can go through a dimension-reduction technique. Output to 3D shows relationships of the unknown case to a cloud of known or unlabeled cases, in which the cloud demonstrates the structure of the population of patients with and without the disease.

This invention provides an Amycolatopsis sp. strain (zhp06), and a method of using the whole cell preparation of the strain for vanillin production. The strain was deposited in China Center for Type Culture Collection on Jul. 26, 2011 with the number of CCTCC NO: M 2011265. Under high concentrations of ferulic acid substrate, the vanillin production by this method can reach more than 10 g/L. The molar conversion rate of ferulic acid is more than 50% and the purity of vanillin is from 80% to 95%. The advantage of this invention includes: repeated use of biocatalyst cells, mild biotransformation condition, low environmental pollution, short production cycle, high product purity and simple purification procedure. It has a great potential for industrial applications.

Embodiments of the present invention disclose an information transmission method and equipment based on CoMP transmission. In the method, a user equipment determines a main transmission point. The user equipment determines RANK information of the main transmission point as well as channel state information corresponding to the RANK information. The user equipment sends the RANK information of the main transmission point and the channel state information to a network side equipment. In the embodiments of the present invention, the UE reports channel state information of limited RANK of every transmission point, channel state information of unlimited RANK of the main transmission point, and relative phase information between the transmission points, etc., to the network side equipment, thereby helping the network side to better implement flexible selection and dynamic switchover of transmission schemes. Moreover, it does not notably increase feedback expenses for the UE.

Optical storage media often contain data structures for a menu suitable for selection of a title, a chapter, a parameter or others. Such menus usually comprise a number of buttons to be displayed, with each button having a state. Possible states of buttons are “unselected”, “selected” or “activated”. According to the invention, the representation of a menu button may vary, depending on its state. An image or an image sequence, e.g. cartoon, may be associated to a buttons state, providing user animation. Further, a sound or sound sequence, e.g. melody or click, may be associated to a buttons state, and may be played back when the button enters this state. A data structure is disclosed which allows storage of such menu data e.g. on a Blu-ray disc.

A method and terminal for improving domain name resolution efficiency is provided. The method is implemented in a terminal supporting IPv4/IPv6 dual stack and comprises: the terminal initiating a domain name resolution request to a domain name system server (S11); and when obtaining a normal response, the terminal recording a first format corresponding to the initiated domain name resolution request as a default initiation format of the current domain name resolution request (S12). The method and terminal provided herewith are used to adapt network environments dynamically to a certain extent so as to increase the domain name request efficiency, thereby improve the fluency for the entire service access.
