On behaviour of holomorphically contractible systems under non-monotonic sequences of sets [PDF]

open access: yes, 2015
The new results concerning the continuity of holomorphically contractible systems treated as set functions with respect to non-monotonic sequences of sets are given. In particular, continuity properties of Kobayashi and Carath\'eodory pseudodistances, as

Individual sequences in large sets of gene sequences may be distinguished efficiently by combinations of shared sub-sequences

open access: yesBMC Bioinformatics, 2005
Background Most current DNA diagnostic tests for identifying organisms use specific oligonucleotide probes that are complementary in sequence to, and hence only hybridise with the DNA of one target species. By contrast, in traditional taxonomy, specimens

Polyphase Spreading Sequences for DS - CDMA Wireless Application [PDF]

open access: yesEngineering and Technology Journal, 2005
In this paper , some of ployphase signature sequences for direct sequence code division multiple access ( DS / CDMA ) system is proposed . The novel sets of polyphase spreading sequences is obtained through the multiplication of the ployphase chirp ...

Z-Complementary Sets Based on Sequences with Periodic and Aperiodic Zero Correlation Zone

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
Methods of constructing Z-complementary sequence sets are described. Different from those constructions using complementary sequences as a kernel, the proposed constructions are based on sequences with periodic and aperiodic zero-correlation zone (PAZCZ)

Randomness extraction and asymptotic Hamming distance [PDF]

open access: yes, 2013
We obtain a non-implication result in the Medvedev degrees by studying sequences that are close to Martin-L\"of random in asymptotic Hamming distance. Our result is that the class of stochastically bi-immune sets is not Medvedev reducible to the class of

Compact Operators on the Sets of Fractional Difference Sequences

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
The sets of fractional difference sequences have been studied in the literature recently. In this work, some identities or estimates for the operator norms and the measure of noncompactness of certain operators on difference sets of sequences of ...

On the heapability of finite partial orders

open access: yes, 2020
We investigate the partitioning of partial orders into a minimal number of heapable subsets. We prove a characterization result reminiscent of the proof of Dilworth's theorem, which yields as a byproduct a flow-based algorithm for computing such a ...

Theory of Analogous Force on Number Sets [PDF]

open access: yes, 2003
A general statistical thermodynamic theory that considers given sequences of x-integers to play the role of particles of known type in an isolated elastic system is proposed.

minSNPs: an R package for the derivation of resolution-optimised SNP sets from microbial genomic data [PDF]

open access: yesPeerJ, 2023
Here, we present the R package, minSNPs. This is a re-development of a previously described Java application named Minimum SNPs. MinSNPs assembles resolution-optimised sets of single nucleotide polymorphisms (SNPs) from sequence alignments such as genome-

A note on discrete sets [PDF]

open access: yes, 2009
We give several partial positive answers to a question of Juhasz and Szentmiklossy regarding the minimum number of discrete sets required to cover a compact space.
