Abstract: A medical device that cuts an object in a body lumen includes: a drive shaft; a shaft portion connected to the drive shaft; a cutting portion connected to the shaft portion; and first and second bearings that rotatably support the shaft portion. The first bearing has a ring shape, the second bearing has a ring shape and is spaced from a proximal side of the first bearing. The shaft portion includes a first sliding portion slidably supported by the first bearing, a second sliding portion slidably supported by the second bearing, and an intermediate portion between the first and second sliding portions. The intermediate portion has a protruding portion protruding radially outward, the protruding portion is disposed between the first bearing (81) and the second bearing in an axial direction, and the shaft portion has a passage that communicates from the first sliding portion to the second sliding portion).

Abstract: The present invention discloses a tetrahydropyrrole compound, a preparation method therefor, a pharmaceutical composition containing the same, and a use thereof. The tetrahydropyrrole compound of the present invention is represented by general formula (I). The tetrahydropyrrole compound of the present invention has better inhibitory effects on the positive symptoms of schizophrenia, and the potency thereof is equivalent to or slightly stronger than that of the positive drug olanzapine. In addition, the compound of the present invention has dual inhibitory effects on D2 receptors and DAT receptors, and is effective for treating schizophrenia and improving negative symptoms and cognitive functions, while also reducing vertebral side effects and prolactin secretion.

Abstract: An ophthalmic system for use in performing angular measurements in relation to a patient's eye. The ophthalmic system can include an optical angular measurement device that can provide angular indicia by, for example, projecting an image of an angular measurement reticle onto a patient's eye or by superimposing an image of an angular measurement reticle onto an image of the patient's eye. The ophthalmic system can include an optical refractive power measurement device for providing desired angular orientations for ocular implants or for incisions. The ophthalmic system can be used, for example, to align a toric intraocular lens to a desired angular orientation.

Abstract: An iterative decoding device includes a decoder, a dual mode determination unit and a dual mode scaling unit. The decoder is utilized for receiving a set of soft information (SI) and iteratively decoding the set of SI and updating the set of SI accordingly to generate a set of updated SI. The dual mode determination unit is coupled to the decoder for generating a determination result according to the set of updated SI. The dual mode scaling unit is coupled to the dual mode determination unit and the decoder for scaling the set of updated SI according to the determination result to generate a set of scaled SI acting as an input of the decoder for next iteration.

Abstract: A decoding method for low density parity check (LDPC) and an electric device using the decoding method are provided. The decoding method includes: receiving a message and executing an iteration decoding to the message; obtaining first belief values of the message in an (i?1)th iteration; obtaining a first energy summation of the first belief values; obtaining second belief values of the message in an ith iteration; obtaining a second energy summation of the second belief values; determining whether the second energy summation is smaller than the first energy summation and whether a difference between the first energy summation and the second energy summation is larger than a first threshold; if yes, generating a decoding result according to the first belief values. Therefore, a bit error rate of the decoding is decreased.
