OBJECTIVES We sought to examine the incidence and possible factors for inducible intra-atrial reentrant tachycardia (IART) in a group of patients after two stages of the Fontan sequence but before the operation. BACKGROUND Intra-atrial reentrant tachycardia occurs in 10% to 40% of patients after the Fontan operation. No data are available regarding the potential for IART after the first two s...

Generalisations of theory change involving arbitrary sets of wffs instead of belief sets have become known as base change. In one view, a base should be thought of as providing more structure to its generated belief set, and can be used to determine the theory change operation associated with a base change operation. In this paper we extend a proposal along these lines by Meyer et al. [12]. We ...

Levenshtein edit operation is a basic string operation – insertion, deletion or substitution of a character in a string. Sequence of edit operations can be used to transform basic word form (lemma) into an inflected form, and the same sequence can can be used to transform lemmata belonging to the same inflectional paradigm. Presented system contains inflection paradigms of over 56000 lemmata fr...

PrefixSpan algorithm based on sequence pattern is an association without generating candidate sequences and only needs to scan the original database twice in whole operation process. Compared with other algorithms, more efficient fast. In this paper, Base Prefix Position Form, PPFPrefixSpan proposed by studying characteristics of optimizing it it. , which solves problem that produces too many d...

hypersensitivity reactions to natural rubber latex have increased recently, especially among people with high exposure to latex allergens. hypersensitivity reactions to latex are related to many conditions like occupational asthma. our study was performed to determine the prevalence of hypersensitivity to natural rubber latex and potential food cross reactions in operation room personnel in shi...

In this article we study the Poisson algebra structure on the homology of the totalization of a fibrant cosimplicial space associated with an operad with multiplication. This structure is given as the Browder operation induced by the action of little disks operad, which was found by McClure and Smith. We show that the Browder operation coincides with the Gerstenhaber bracket on the Hochschild h...

Two digital LSI implementation methods for nonlinear resistive networks are proposed; one is for pixel-parallel operation and the other is for pixel-serial operation. we have designed digital circuits that emulate the operation of analog nonlinear resistive networks by discrete-time dynamics based on clock operation. The steady state of the networks is obtained by repeating the updating sequenc...

Taking the two position way valve unloading circuit, accumulator double pump liquid control sequence circuit as examples, paper analyses reason of abnormal operation several hydraulic puts forward concrete measures, which provides basis for design and system.

multileaf collimator (mlc) is among the radiation field shaping systems used for conformal radiotherapy and intensity modulation radiation therapy techniques. the mlc system that has been designed and fabricated in this study includes 52 leaves, 52 stepper motors, 2 dc motors, 16 programmable logic controllers (plcs) and one human machine interface (hmi). this system can be mounted on conventio...

this paper presented a mixed integer programming for integrated scheduling and process planning. the presented process plan included some orders with precedence relations similar to multiple traveling salesman problem (mtsp), which was categorized as an np-hard problem. these types of problems are also called advanced planning because of simultaneously determining the appropriate sequence and m...
