The author introduced the “geometric AIC” and the “geometric MDL” as model selection criteria for geometric fitting problems. These correspond to Akaike’s “AIC” and Rissanen’s “BIC”, respectively, well known in the statistical estimation framework. Another criterion well known is Schwarz’ “BIC”, but its counterpart for geometric fitting has been unknown. This paper introduces the corresponding ...

The localization of oocyte-specific determinants in the form of mRNAs to the pro-oocyte is essential for the establishment of oocyte identity. Localization of the Bicaudal-D (Bic-D) protein to the presumptive oocyte is required for the accumulation of Bic-D and other mRNAs to the pro-oocyte. The Bic-D protein contains four well-defined heptad repeat domains characteristic of intermediate filame...

OBJECTIVE This article aims to describe the characteristics of the binaural interaction component (BIC) of speech-evoked auditory brainstem response (ABR). MATERIALS AND METHODS All 15 subjects had normal peripheral hearing sensitivity. ABRs were elicited by speech stimulus /da/. RESULTS The first BIC (BIC-SP1) in the speech-evoked ABR occurred at around 6 ms in the region of peak V. The se...

Bayesian information criterion (BIC) is a common model selection criterion for mixtures of factor analyzers (MFA). However, it is found that BIC penalizes each factor analyzer implausibly using the whole sample size. In this paper, we propose a new criterion for MFA called hierarchical BIC (H-BIC). Formally, the main difference from BIC is that H-BIC penalizes each factor analyzer using its own...

INTRODUCTION This cross-sectional study examined variables associated with body image concern (BIC) and whether these associations differed between female and male students in Egypt. During the period 2009-2010, 3271 undergraduate students (1663 females, 1504 males) at Assuit University in Egypt completed a self-administered questionnaire that assessed BIC and other socio-demographic and health...

Bicaudal-C (Bic-C) encodes an RNA-binding protein required maternally for patterning the Drosophila embryo. We identified a set of mRNAs that associate with Bic-C in ovarian ribonucleoprotein complexes. These mRNAs are enriched for mRNAs that function in oogenesis and in cytoskeletal regulation, and include Bic-C RNA itself. Bic-C binds specific segments of the Bic-C 5' untranslated region and ...

background and objective: amygdala contains central nucleus which is the region rich of γ-aminobutyric acid (gaba-a) receptors and plays a key role in modulating behavior and sleep homeostasis. furthermore, dysfunction of amygdala probably contributes to anxiety and mood disorders. in this study, we evaluated the association between acute sleep deprivation (asd) and anxiety through gaba-a recep...

Bicaudal-D (Bic-D) is essential for the establishment of oocyte fate and subsequently for polarity formation within the developing Drosophila oocyte. To find out where in the germ cells Bic-D performs its various functions we made transgenic flies expressing a chimeric Bic-D::GFP fusion protein. Once Bic-D::GFP preferentially accumulates in the oocyte, it shows an initial anterior localization ...
