    Abstract: A double-sided needle groove, a frame body and a puncture frame, wherein the double-sided needle groove has an axisymmetric outer contour, and is provided at one side with at least one needle slot a (1) and at the other side with at least one needle slot b (2); and the needle slot b (2) is fan-shaped. The double-sided needle groove is provided with one or more needle slots a (1) having a fixed needle insertion angle and a needle slot b (2) having an adjustable needle insertion angle, and the needle slot a (1) and the needle slot b (2) respectively correspond to the diameters of puncture needles and may be designed to meet multiple width specifications. During the performance of a B-ultrasound puncture operation, based on operation requirements of a surgeon for a fixed or adjustable angle, there is only a need to switch front and back sides of the double-sided needle groove, thus avoiding the need for an additional puncture frame, and switch the needle slots according to the diameters of the puncture needles. As can be seen, the double-sided needle groove can be applied to various types of B-ultrasound puncture operations and can effectively reduce the number of accessories in the puncture operations, thereby providing fast installation, saving resources and reducing costs.

    Abstract: A needle guide holder, which is used for a fixing medical puncture needle and a ultrasonic probe, comprises a holder body (1a, 1b) and a fixing device (2a, 2b) used in cooperation with the holder body (1a, 1b). The fixing device (2a, 2b) is mounted onto the holder body (1a, 1b) and provided with a weakening portion (23a, 23b). The needle guide holder is designed to be disposable, thereby avoiding the possibility of cross-infection caused by using the same needle guide holder on different patients. The needle guide holder can be used on one and same patient to perform a number of treatments just through the replacement of a sliding frame and without replacing the fixing device and a fixing frame. In a treatment process, the puncture needle is left in the body for a subsequent treatment, while the needle guide holder and the ultrasonic probe can be removed from the human body.

    Abstract: The present disclosure relates to the field of microelectronics manufacture and memories. A three-dimensional multi-bit non-volatile memory and a method for manufacturing the same are disclosed. The memory comprises a plurality of memory cells constituting a memory array. The memory array may comprise: a gate stack structure; periodically and alternately arranged gate stack regions and channel region spaces; gate dielectric layers for discrete charge storage; periodically arranged channel regions; source doping regions and drain doping regions symmetrically arranged to each other; bit lines led from the source doping regions and the drain doping regions; and word lines led from the gate stack regions. The gate dielectric layers for discrete charge storage can provide physical storage spots to achieve single-bit or multi-bit operations, so as to achieve a high storage density. According to the present disclosure, the localized charge storage characteristic of the charge trapping layer and characteristics such as a longer effective channel length and a higher density of a vertical memory structure are utilized, to provide multiple storage spots in a single memory cell. Therefore, the storage density is improved while good performances such as high speed are ensured.

    Abstract: A method for determining the encoding law of an incoming signal in a network which possibly contains an A-&mgr; or &mgr;-A conversion includes obtaining digital impairment learning (DIL) probing data, generating an ordered table of levels therefrom, using the table to find two functions, and using a logical analysis of the functions to determine the encoding law of the signal. A first function is a maximum from the values DL(i) and the threshold Th1 which are less than T(i), with T(i)=a +bi, and DL(i)=L(i+16)−2L(i) with L(i) being the DIL signal corresponding to the transmitted Ucode=i. A second function Q is defined by: Q = 1 2 ⁢ ( ∑ i = i5 i - i6 ⁢   ⁢ DL ⁡ ( i ) + ∑ i = i5 i = i6 ⁢   ⁢ DLm ⁡ ( i ) ) - S m ⁢ Ly 2 2 where DLm(i) is the median value of a windowed group of values for DL(i) where i ranges from i5 to i6, Ly=i6−i5−1, and Sm is a mean of a windowed group of slopes, wherein each slope relates to the difference between certain DLm(i) values.
