We prove that the criterion for Markov equivalence provided by Zhao et al. (2005) may involve a set of features of a graph that is exponential in the number of vertices. Zhao et al. (2005) define a collider path ν = 〈v1, . . . , vn〉 to be minimal if there is no subsequence of vertices 〈v1 = vi1 , . . . , vik = vn〉 which forms a collider path. They use this(More)
MOTIVATION Histone proteins play important roles in chromosomal functions. They are significantly evolutionarily conserved across species, which suggests similarity in their transcription regulation. The abundance of experimental data on histone promoters provides an excellent background for the evaluation of computational methods. Our study addresses the(More)
UNLABELLED Dragon Promoter Mapper (DPM) is a tool to model promoter structure of co-regulated genes using methodology of Bayesian networks. DPM exploits an exhaustive set of motif features (such as motif, its strand, the order of motif occurrence and mutual distance between the adjacent motifs) and generates models from the target promoter sequences, which(More)
Gougerot-Sjögren syndrome is an autoimmune disease of idiopathic etiology which has a slew of signs and symptoms all over the body especially within the mucosal surfaces. Epitomical of its cardinal symptoms of the primary type are xerophthalmia, xerostomia and vaginal dryness. For secondary Sjögren syndrome, it involves another connective tissue disorder,(More)
Single unit microneurography was used to record the firing characteristics of the four classes of foot sole cutaneous afferents [fast and slowly adapting type I and II (FAI, FAII, SAI, and SAII)] in response to sinusoidal vibratory stimuli. Frequency (3-250 Hz) and amplitude (0.001-2 mm) combinations were applied to afferent receptive fields through a 6-mm(More)
Increased inter-equipment connectivity coupled with advances in Web technology allows ever escalating amounts of physiological data to be produced, far too much to be displayed adequately on a single computer screen. The consequence is that large quantities of insignificant data will be transmitted and reviewed. This carries an increased risk of overlooking(More)
Summary: DPM is a tool to model promoter structure of coregulated genes using methodology of Bayesian networks. DPM exploits an exhaustive set of motif features (such as motif, its strand, the order of motif occurrence, and mutual distance between the adjacent motifs) and generates models from the target promoter sequences, which may be used to: a/ detect(More)
Histones constitute a rich protein family that is evolutionarily conserved across species. They play important roles in chromosomal functions in cell, such as chromosome condensation, recombination, replication, and transcription. We have modeled histone gene 5' end segments covering [-50,+500] relative to transcription start sites (TSSs). These segments(More)
