This paper presents an analysis of the basic primary stress system in Thompson River Salish (TRS), an Interior Salishan language spoken in British Columbia, Canada. The lexical accent system in TRS exhibits a pattern of conflicting directionality: In words with no accented morphemes, stress falls close to the left edge of the prosodic word (PrWd); in words with accented morphemes, stress falls ...
introduction: the critical dependence of healthcare services systems on information along with the indigenous restriction of paper documents in satisfying this need has caused a trend toward computer information systems. the main goal of such systems is to achieve electronic health records (ehr). however, implementation of ehr in healthcare organizations is difficult and complicated. this resea...
Although multiple sequence alignments (MSAs) are essential for a wide range of applications from structure modeling to prediction of functional sites, construction of accurate MSAs for distantly related proteins remains a largely unsolved problem. The rapidly increasing database of spatial structures is a valuable source to improve alignment quality. We explore the use of 3D structural informat...
Summary: Most multi-alignment methods are fully automated, i.e. they are based on a fixed set of mathematical rules. For various reasons, such methods may fail to produce biologically meaningful alignments. Herein, we describe a semi-automatic approach to multiple sequence alignment where biological expert knowledge can be used to influence the alignment procedure. The user can specify parts of...
Word alignment methods can gain valuable guidance by ensuring that their alignments maintain cohesion with respect to the phrases specified by a monolingual dependency tree. However, this hard constraint can also rule out correct alignments, and its utility decreases as alignment models become more complex. We use a publicly available structured output SVM to create a max-margin syntactic align...
This chapter will review a particular approach to deformable face alignment coined constrained local models (CLM). The approach leverages the excellent generalisation properties of local appearance representations of parts and the strong global constraints imposed by the geometrical relationships between part locations. We begin by posing CLM in the general context of deformable face alignment,...
Dependency cohesion refers to the observation that phrases dominated by disjoint dependency subtrees in the source language generally do not overlap in the target language. It has been verified to be a useful constraint for word alignment. However, previous work either treats this as a hard constraint or uses it as a feature in discriminative models, which is ineffective for large-scale tasks. ...
Please note that all the discussion referring to Theorem 5.4.1 has been revised accordingly. The corrected version of Chapter 5 has been published as follows: [WXSP15a] Zhao Wang, Ming Xiao, Mikael Skoglund, and H. Vincent Poor, “Secure degrees of freedom of wireless X networks using artificial noise alignment,” IEEE Trans. Commun., to appear. Online access: http://arxiv.org/abs/1410.5009. • 83...
This paper addresses the problem of temporal constraints in the Viterbi algorithm using conditional transition probabilities. The results here presented suggest that in a speaker dependent small vocabulary task the statistical modelling of state durations is not relevant if the max and min state duration restrictions are imposed, and that truncated probability densities give better results than...
SUMMARY MuSiC is a web server to perform the constrained alignment of a set of sequences, such that the user-specified residues/nucleotides are aligned with each other. The input of the MuSiC system consists of a set of protein/DNA/RNA sequences and a set of user-specified constraints, each with a fragment of residue/nucleotide that (approximately) appears in all input sequences. The output of ...
