How the mitosis of neuroepithelial stem cells is restricted to the apical ventricular area remains unclear. In zebrafish, the mosaic eyes(rw306) (moe/epb41l5(rw306)) mutation disrupts the interaction between the putative adaptor protein Moe and the apicobasal polarity regulator Crumbs (Crb), and impairs the maintenance of neuroepithelial apicobasal polarity. While Crb interacts directly with No...

We present an updated estimate of the cosmic radio background (CRB) and corresponding attenuation lengths for ultra-high energy photons. This new provides associated uncertainties as a function frequency derived from observational constraints on key physical parameters. also expected variation in spectrum CRB these parameters, well accounting spectral index among population galaxies. The presen...

Crumbs proteins are important regulators of epithelial polarity. In C. elegans, no essential role for the two described Crumbs homologs has been uncovered. Here, we identify and characterize an additional Crumbs family member in C. elegans, which we termed CRB-3 based on its similarity in size and sequence to mammalian CRB3. We visualized CRB-3 subcellular localization by expressing a translati...

Joint carrier frequency offset (CFO) and channel estimation is considered for two-way relay networks (TWRNs). Existing estimators provide only the convolved channel parameters and themixed CFO values. In contrast, estimators using a superimposed training strategy are developed for the individual frequency and channel parameters. Depending on the number of pilots, three different estimators are ...

The primary purpose of this pilot study was to test the feasibility of an intervention designed to reduce care-resistant behaviors (CRBs) in persons with moderate-to-severe dementia during oral hygiene activities. The intervention, Managing Oral Hygiene Using Threat Reduction (MOUTh), combined best oral hygiene practices with CRB reduction techniques. Oral health was operationalized as the tota...

The Ormia ochracea is able to locate a cricket's mating call despite the small distance between its ears compared with the wavelength. This phenomenon has been explained by the mechanical coupling between the ears. In this paper, it is first shown that the coupling enhances the differences in times of arrival and frequency responses of the ears to the incoming source signals. Then, the accuracy...

The continuity of duplex DNA is generally considered a prerequisite for chromosome continuity. However, as previously shown in yeast as well as human cells, the introduction of a double-strand break (DSB) does not generate a chromosome break (CRB) in yeast or human cells. The transition from DSB to CRB was found to be under limited control by the tethering function of the RAD50/MRE11/XRS2 (MRX)...

and documented. A predicted moderate to high risk of death from community-acquired pneumonia is a highly relevant piece of information required to mount an ethically valid treatment recommendation and decision, particularly in those patients with pneumonia regarded to be a terminal event. Nevertheless, we recalculated the predictions of the CRB-65 score excluding all those who died without havi...

We consider the problem of sampling clock synchronization and channel estimation for Orthogonal Frequency Division Multiplex (OFDM) systems. In such systems, when the number of subcarriers is large, a sampling clock frequency mismatch between the transmitter and the receiver dramatically degrades the performance. So far, the literature proposes ad-hoc estimation algorithms. However, a complete ...

Theoretical light curves of four recurrent novae in outburst are modeled to obtain various physical parameters. The four objects studied here are those with a red giant companion, i.e., T Coronae Borealis, RS Ophiuchi, V745 Scorpii, and V3890 Sagittarii. Our model consists of a very massive white dwarf (WD) with an accretion disk and a red giant companion. Light curve calculation includes refle...
