چکیده

When many cells divide, the nuclear envelope poses a problem: the spindle microtubules can't access the chromosomes. Two recent papers in Cell describe how the spindle solves this problem by literally pulling open the nucleus at the beginning of mitosis.

Frequency Effects of Regular Past Tense Forms in English on Native Speakers’ and Second Language Learners’ Accuracy Rate and Reaction Time

There is substantial debate over the mental representation of regular past tense forms in both first language (L1) and second language (L2) processing. Specifically, the controversy revolves around the nature of morphologically complex forms such as the past tense –ed in English and how morphological structures of such forms are represented in the mental lexicon. This study focuses on the resul...

Trim and Maneuverability Analysis Using a New Constrained PSO Approach of a UAV

Performance characteristic of an Unmanned Air Vehicle (UAV) is investigated using a newly developed heuristic approach. Almost all flight phases of any air vehicle can be categorized into trim and maneuvering flights. In this paper, a new envelope called trim-ability envelope, is introduced and sketched within the conventional flight envelope for a small UAV. Optimal maneuverability of the inte...

Single station estimation of earthquake early warning parameters by using amplitude envelope curve

In this study, new empirical relationships to estimate key parameters in Earthquake Early Warning (EEW) system including magnitude, epicentral distance and Peak Ground Acceleration (PGA) are introduced based on features of the initial portion of P-wave’s amplitude envelope curve. For this purpose, 226 time series recorded by bore-hole accelerometers of Japanese KiK-net are processed for earthq...

Envelope-based inter-aural time difference localization training to improve speech-in-noise perception in the elderly

Background: Many elderly individuals complain of difficulty in understanding speech in noise despite having normal hearing thresholds. According to previous studies, auditory training leads to improvement in speech-in-noise perception, but these studies did not consider the etiology, so their results cannot be generalized. The present study aimed at investigating the effectiveness of envelope-b...

Composition of the plant nuclear envelope: theme and variations.

The nuclear envelope is the hallmark of all eukaryotic cells, separating the nucleoplasm from the cytoplasm. At the same time, the nuclear envelope allows for the controlled exchange of macromolecules between the two compartments through nuclear pores and presents a surface for anchoring and organizing cytoskeletal components and chromatin. Although our molecular understanding of the nuclear en...
