The Bayesian information criterion (BIC) is a model selection criterion that has previously been applied to speaker segmentation of broadcast news by several researchers. The BIC approach treats speaker segmentation as a model selection problem. As the BIC requires the estimation of the sample covariance matrix, its performance tends to deteriorate as the speaker-turn duration decreases. It is ...

Quantum mechanics predicts that certain stationary potentials can sustain bound states with an energy buried in the continuous spectrum of scattered states, the so-called bound states in the continuum (BIC). Originally regarded as mathematical curiosities, BIC have found an increasing interest in recent years, particularly in quantum and classical transport of matter and optical waves in mesosc...

BACKGROUND Several tests have been evaluated in horses for quantifying insulin dysregulation to support a diagnosis of equine metabolic syndrome. Comparing the performance of these tests in the same horses will provide clarification of their accuracy in the diagnosis of equine insulin dysregulation. OBJECTIVES The aim of this study was to evaluate the agreement between basal serum insulin con...

Local likelihood estimation has proven to be an eeective method for obtaining estimates of parameters that vary with a covariate. To obtain useful estimates of such parameters, approximating models are used. In such cases it is useful to consider window based estimates. We may need to choose between competing approximating models. In this paper we propose a modiication to the methods used to mo...

Abstract All-dielectric metasurfaces supporting photonic bound states in the continuum (BICs) are an exciting toolkit for achieving resonances with ultranarrow linewidths. However, transition from theory to experimental realization can significantly reduce optical performance of BIC-based nanophotonic systems, severely limiting their application potential. Here, we introduce a combined numerica...

The auditory peripheral system filters broadband sounds into narrowband waves and decomposes narrowband waves into quickly varying temporal fine structures (TFSs) and slowly varying envelopes. When a noise is presented binaurally (with the interaural correlation being 1), human listeners can detect a transient break in interaural correlation (BIC), which does not alter monaural inputs substanti...

In the Drosophila ovary, the Bicaudal-D (Bic-D) gene is required for the differentiation of one of 16 interconnected cystocyte sister cells into an oocyte. A new class of Bic-Dnull alleles reveals a novel requirement for Bic-D for zygotic viability. In the germ line, the null mutations show that developmental processes that take place in germarial region 1, even those that create asymmetry, are...

miRs (microRNAs) post-transcriptionally regulate gene expression mainly by repressing translation or by inducing mRNA degradation. Dicer, an enzyme responsible for miR biogenesis, is required for T-cell function, suggesting regulatory roles for miRs in lymphocytes. However, specific roles for individual miRs are only just beginning to emerge. miR-155 is encoded within an exon of the non-coding ...

BACKGROUND After radiofrequency (RF) ablation of atrial flutter (AFL), the demonstration of bidirectional isthmus conduction (BIC) block is considered the hallmark of a successful procedure. The purpose of our study was to test the persistence of BIC block after isoproterenol administration and to evaluate the importance of this finding with regard to AFL recurrences. METHODS AND RESULTS RF a...

The Bayesian Information Criterion (BIC) has been widely used for estimating the number of data clusters in an observed data set for decades. The original derivation, referred to as classic BIC, does not include information about the specific model selection problem at hand, which renders it generic. However, very little effort has been made to check its appropriateness for cluster analysis. In...
