We describe a frequent itemset mining algorithm and implementation based on the well-known algorithm FPgrowth. The theoretical difference is the main data structure (tree), which is more compact and which we do not need to rebuild for each conditional step. We thoroughly deal with implementation issues, data structures, memory layout, I/O and library functions we use to achieve comparable perfo...

SUMMARY The ring F p + uF p + · · · + u k−1 F p may be of interest in coding theory, which have already been used in the construction of optimal frequency-hopping sequence. In this work, cyclic codes over F p + uF p + · · ·+u k−1 F p which is an open problem posed in [1] are considered. Namely, the structure of cyclic code over F p + uF p + · · · + u k−1 F p and that of their duals are derived.

Background During automated radiofrequency (RF) annotation-guided pulmonary vein isolation (PVI), respiratory motion adjustment (RMA) is recommended, yet lacks in vivo validation. Methods Following contact force (CF) PVI (continuous RF, 30 W) using general anesthesia and RF annotation-guidance (VISITAG™: force-over-time 100% minimum 1 g; 2 mm position stability; ACCURESP™ RMA “off”) 25 patients...

Prostaglandin F(2alpha) receptors (FP) are G protein-coupled receptors that bind prostaglandin F(2alpha) (PGF(2alpha)), resulting in the activation of an inositol phosphate (IP) second messenger pathway. Alternative mRNA splicing generates two FP receptor isoforms. These isoforms, designated FP(A) and FP(B), are otherwise identical except for their carboxyl termini. FP(B) is essentially a trunc...

objective: there is no definitive data on the strength of glass fiber and cast posts with different length. this in vitro study was designed to investigate and compare the effect of length on the retentive strength of glass fiber and cast posts. materials and methods: sixty recently extracted intact maxillary canine teeth were cut 1mm above the cej. the specimens were endodontically treated and...

When FP measurement methods are different between the same functional size projects, FPs are different between them. FP measurement methods are often customized by software vendors. To reinforce accountability for a customer, FP based on a customized method should be transformed to FP based on a standard method. So we proposed two derivation methods of FP transformation formulas. One method is ...

We determine the probability that a randomly chosen elliptic curve E/Fp over a randomly chosen prime field Fp has an `-primary part E(Fp)[`∞] isomorphic with a fixed abelian `-group H (`) α,β = Z/` × Z/`. We show that the probability agrees with the one predicted by a natural though unproven equidistribution hypothesis for Frobenius elements in GL(2,Z`). Probabilities for “|E(Fp)| divisible by ...

When the interval between a warning signal (WS) and an imperative signal (IS), termed the foreperiod (FP), is variable across trials, reaction time (RT) to the IS typically decreases with increasing FP length. Here we examined the auditory filled-FP effect, which refers to a performance decrement after FPs filled with irrelevant auditory stimulation compared to FPs without additional stimulatio...
