Phosphatase PP2A and microtubule-mediated pulling forces disassemble centrosomes during mitotic exit
Centrosomes are microtubule-nucleating organelles that facilitate chromosome segregation and cell division in metazoans. Centrosomes comprise centrioles that organize a micron-scale mass of protein called pericentriolar material (PCM) from which microtubules nucleate. During each cell cycle, PCM accumulates around centrioles through phosphorylation-mediated assembly of PCM scaffold proteins. Du...
High-power lithium-ion capacitors (LiC) are hybrid energy storage systems (EES) with the combined benefits of batteries (LiB) and supercapacitors, such as high specific energy, power, a long lifetime. Such advanced technology can be used in high-power applications when charging discharging demanded. Nevertheless, their performance lifetime highly depend on temperature. In this context, paper pr...
Pancreatic carcinoma occasionally associated with prominent mucin production and this type of tumor designated as PCM (pancreatic carcinoma with prominent mucin production) was diagnosed depends on subjective estimation of the amount of mucous area, and there has been no report on a quantitative evaluation of the amount of mucinous area in the tumor. To examine the feature of PCM, we analyzed 9...
در این تحقیق، عملکرد سیستم نوین ذخیره بلند مدت انرژی خورشیدی جهت گرمایش با استفاده از محاسبات شبیه سازی مورد مطالعه قرار گرفت. سیستم شامل ماده با تغییر فاز 6 H2o، CaCl2 برای ذخیره حرارت کوتاه مدت، محفظه ذخیره حرارت محسوس - که دارای تانک آب گرم بوده و بوسیله قلوه سنگ احاطه شده است - و پمپ حرارتی برای ذخیره حرارت میان مدت و همچنین خاک برای ذخیره حرارت بلند مدت می...
This paper presents an investigation on microencapsulation of paraffin as a phase change materials (PCMs) for application in buildings. Encapsulated PCM particles were prepared by suspension-like polymerization technique. The effect of surfactant concentration and mass ratio of PCM to monomer on the final characteristics and performance of the microcapsules were investigated. The distribution o...
Phase change memory (PCM) has emerged as a promising candidate for next-generation memories, owing to its low power consumption, non-volatility, and high storage-density. However, PCM has limited write endurance, i.e., it can only undergo a limited number of write operations, leading to a short lifecycle. Thus, it is an important issue to find out an efficient way to use PCM in memory hierarchy...
In this paper, we take a new look at the possibilistic c-means (PCM) and adaptive PCM (APCM) clustering algorithms from the perspective of uncertainty. This new perspective offers us insights into the clustering process, and also provides us greater degree of flexibility. We analyze the clustering behavior of PCM-based algorithms and introduce parameters σv and α to characterize uncertainty of ...
Paracoccidioidomycosis (PCM) is a systemic granulomatous human mycosis caused by fungi of the genus Paracoccidioides, which is geographically restricted to Latin America. Inhalation of spores, the infectious particles of the fungus, is a common route of infection. The PCM treatment of choice is azoles such as itraconazole, but sulfonamides and amphotericin B are used in some cases despite their...
In order to reduce the heat transfer between indoor and outdoor environments influence of ambient temperature fluctuation on environment, adding micro-PCM building envelope is one effective means. Micro-PCM can ?intelligently? control by absorbing or releasing during phase change maintain stability. this paper, temperature-adjustable mortar was prepared using with a 25?C, painted surface cement...
Although it is known that the centrioles play instructive roles in pericentriolar material (PCM) assembly and that the PCM is essential for proper centriole formation, the mechanism that governs centriole-PCM interaction is poorly understood. Here, we show that ATF5 forms a characteristic 9-fold symmetrical ring structure in the inner layer of the PCM outfitting the proximal end of the mother c...
