This paper addresses the problem of pilot reuse among the inter-cell user terminals (UTs) for massive multi-input multi-output (MIMO) transmission. Firstly, we derive the closed-form expression of the non-asymptotic downlink (DL) achievable rate by using the second-order channel statistical information. Based on this, we present the spatial orthogonality(More)
Accurate gene model annotation of reference genomes is critical for making them useful. The modENCODE project has improved the D. melanogaster genome annotation by using deep and diverse high-throughput data. Since transcriptional activity that has been evolutionarily conserved is likely to have an advantageous function, we have performed large-scale(More)
Integrating ad hoc wireless communication into dynamic, complex spaces is an inherently challenging task. In this paper, we analyze over 2,800 anonymous pedestrian trajectories captured in a busy train station so as to uncover the unique patterns that emerge as people walk and change mutual distances. We then discuss how our analysis of proximity-based(More)
A clinical pathway implements best medical practices and represents sequencing and timing of interventions by clinicians for a particular clinical presentation. We used a Bayesian belief network (BBN) to model a clinical pathway for radical prostatectomy and to categorize patient's length of stay (LOS) as being met or delayed given the patient's outcomes(More)
There has been a renewed interest in investigating the role of stabilizing selection acting on genome-wide traits such as codon usage bias. Codon bias, when synonymous codons are used at unequal frequencies, occurs in a wide variety of taxa. Standard evolutionary models explain the maintenance of codon bias through a balance of genetic drift, mutation and(More)
Cyber-bullying is widely recognized as a serious social problem, especially for adolescents and it is also becoming a threat to the viability of online social networks. Several researchers have proposed digital-communication based frameworks whose goal is to help detect bullying in social networks. In this paper, our study focuses on detecting(More)
