Dynamic protein localization is an integral component of the regulatory circuit that drives the Caulobacter cell cycle. The ClpXP protease is localized to the Caulobacter cell pole, where it catalyzes the degradation of the CtrA master regulator at specific times in the cell cycle. Clearance of active CtrA at the G1/S transition allows the initiation of DNA replication and cell-cycle progressio...

Currently, and throughout much of the Amazonian, the mean annual surface temperatures of Mars are so cold that basal melting does not occur in ice sheets and glaciers and they are cold-based. The documented evidence for extensive...

The distribution of structural planes is complex and irregular. How to quickly effectively obtain the occurrence characteristics improve efficiency data processing a key technical issue in plane analysis. paper combined fuzzy equivalent clustering algorithm, rose diagram drawing method, C++ language, developed system for pole rock mass planes, verified practicability through an engineering case...

UNLABELLED Spatial organization within bacteria is fundamental to many cellular processes, although the basic mechanisms underlying localization of proteins to specific sites within bacteria are poorly understood. The study of protein positioning has been limited by a paucity of methods that allow rapid large-scale screening for mutants in which protein positioning is altered. We developed a ge...

This paper presents a spectral and photometric study of the poorly studied polar BM CrB. Three states brightness signs transition from one-pole to two-pole accretion mode were found by an analysis ZTF data. It is shown that low state high changes longitude main spot (by $\approx 17^{\circ}$) increases its elongation 10^{\circ}$). The spectra contain Zeeman absorptions H$\alpha$ line which are f...

Comprehensive geriatric assessment has become synonymous with geriatric practice. This includes evaluation of the older person's physical and mental health, and the functional and social status. We propose a new way of representing a person's condition, called the "polar diagram". This shows the subject's scores on the evaluation scales that are arranged in radial positions inside a circle. The...

The solar polar fields reverse because magnetic flux from decaying sunspots moves towards the poles, with a preponderance of flux from the trailing spots. If there is a strong asymmetry in the sense that most activity is in the Northern Hemisphere, then that excess flux will move to the North Pole and reverse that pole first. If later on, there is more activity in the South, then that flux will...

Abstract The vast Greenland and Antarctic Ice Sheets are covered by many tens of meters polar firn, which is snow that years to centuries old has experienced significant metamorphism. Both ice-sheet modeling decoding satellite data require knowledge the thermal conductivity firn with depth, yet direct measurements not available for depths below top several meters. We present first effective ove...

In Drosophila, pole cells, the progenitors of the germ line, are induced by the factors localized in the posterior pole region of oocytes and cleavage embryos, or germ plasm. Polar granules in germ plasm are electron-dense structures and have been proposed to contain factors essential for pole cell formation. Mitochondrially encoded large ribosomal RNA (mtlrRNA) has been identified as a compone...
