Visualizing static networks is already difficult, but exploring dynamic networks is even more challenging due to the complexity of the tasks involved. Some require aggregation over time; others require observing the topology at one given time or tracking the evolution of edge weights. Due to this wide spectrum of tasks, one visual encoding will hardly fit all tasks effectively; multiple complem...

The purpose of this note is to investigate the close relationship that exists between the Euler-Seidel matrix [3, 4, 5, 6, 10] of an integer sequence, and the Hankel matrix [9] of that sequence. We do so in the context of sequences that have integral moment representations, though many of the results are valid in a more general context. While partly expository in nature, the note assumes a cert...

OBJECTIVES Lack of familiarity between teammates is linked to worsened safety in high risk settings. The emergency department (ED) is a high risk healthcare setting where unfamiliar teams are created by diversity in clinician shift schedules and flexibility in clinician movement across the department. We sought to characterise familiarity between clinician teammates in one urban teaching hospit...

Models of recognition memory have postulated that the mammillo-thalamic tract (MTT)/anterior thalamic nucleus (AN) complex would be critical for recollection while the Mediodorsal nucleus (MD) of the thalamus would support familiarity and indirectly also be involved in recollection (Aggleton et al., 2011). 12 patients with left thalamic stroke underwent a neuropsychological assessment, three ve...

A new set of ‘‘Familiarity-controlled word lists 2003” (FW03) has been developed for a spoken-word intelligibility test in Japanese. FW03 consists of 20 lists of 50 words in four word-familiarity ranks (i.e., 4000 words in total). The entropy of (a) initial moras and (b) sequences consisting of a vowel and a following consonant was maximized in the word lists within each word-familiarity rank. ...

In this article, we discuss the remarkable connection between two very different fields, number theory and nuclear physics. We describe the essential aspects of these fields, the quantities studied, and how insights in one have been fruitfully applied in the other. The exciting branch of modern mathematics – random matrix theory – provides the connection between the two fields. We assume no det...

Contemporary memory theories often distinguish between contextual recollection and acontextual familiarity as two fundamentally different types of recognition memory. It is currently unclear whether recollection and familiarity are supported by two correspondingly distinct retrieval mechanisms, or whether the same type of retrieval processing supports both phenomena. Electrophysiological findin...

Despite its apparent similarity to the (easily-computable) determinant, it is believed that there is no polynomial-time algorithm for computing the permanent of an arbitrary matrix. In this survey, we review the known approaches for efficiently estimating the permanent and discuss their relative merits and limits. Emphasis is placed on the most successful approach to date, which is based on ran...

The neural substrates of recognition memory retrieval were examined in a functional magnetic resonance imaging study designed to separate activity related to recollection from that related to continuous variations in familiarity. Across a variety of brain regions, the neural signature of recollection was found to be distinct from familiarity, demonstrating that recollection cannot be attributed...

Recent research has shown that familiarity contributes to associative memory when the to-be-associated stimuli are unitized during encoding. However, the specific processes underlying familiarity-based recognition of unitized representations are still indefinite. In this study, we present electrophysiologically dissociable early old/new effects, presumably related to two different kinds of fami...
