Nitidine chloride (NC), a bioactive alkaloid isolated from Zanthoxylum nitidum, has been used as a herbal ingredient in toothpaste that prevents cavities for decades. It also displays potential antitumor and anti-inflammation properties. However, its anticatabolic effect on bone is not known. We investigated the effect of NC on osteoclastogenesis, bone resorption and rANKL-induced NF-kappa B and NFATc1 signalling. In mouse-derived bone marrow monocytes (BMMs), NC suppressed rANKLinduced multinucleated tartrate-resistant acid phosphatase (TrAP)-positive osteoclast formation and bone resorption in a dose dependent manner. NC attenuated the expression of osteoclast marker genes including cathepsin K, d2, calcitonin receptor, NFATc1, and TrAP. Further, NC inhibited rANKL-activated NF-kappa B and NFATc1 signalling pathways. In vivo study revealed that NC abrogated oestrogen deficiency-induced bone loss in ovariectomized mice. Histological analysis showed that the number of osteoclasts was significantly lower in NC-treated groups. Collectively, our data demonstrate that NC suppressed osteoclastogenesis and prevented OVX-induced bone loss by inhibiting rANKL-induced NF-kappa B and NFATc1 signalling pathways. NC may be a natural and novel treatment for osteoclast-related bone lytic diseases.

distributed caching at the edge can reduce the backhaul resource consumption, which is considered as a major way to improve network capacity in dense small cell networks. In this paper, we consider the caching-based content distribution in dense small cell networks. In such a content distribution system, the most critical metric is the user request blocking probability. A user's request will be rejected if the content is not cached at the associated SBS and there is no backhaul resource available at the SBS. In this paper, we develop an analytic model to derive the blocking probability as the function of cache capacity, available backhaul resource, and request arrival rates. Based on the analysis, the optimal resource configuration is determined to minimize the blocking probability. Extensive simulations are conducted to validate our analysis.

These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry community. They provide the theory and key practical aspects of flow cytometry enabling immunologists to avoid the common errors that often undermine immunological data. Notably, there are comprehensive sections of all major immune cell types with helpful Tables detailing phenotypes in murine and human cells. The latest flow cytometry techniques and applications are also described, featuring examples of the data that can be generated and, importantly, how the data can be analysed. Furthermore, there are sections detailing tips, tricks and pitfalls to avoid, all written and peer-reviewed by leading experts in the field, making this an essential research companion.

dC and AC transport properties on La_(0.8)Sr_(0.2)MnO_3

Magnetoresistive sensor can be widely used in modem transportation field, such as the vehicle positioning and navigation system, vehicle detection system, and intelligent transportation system. In order to improve the efficiency of magnetoresistive sensor, we synthesized ***.2MnO3 polycrystalline bulks at different sintering temperatures and investigated their dC and AC transport properties in this work. As a result, all samples showed insulator-metal （I-M） phase transition, and the transition temperature （TI-M） shifted to higher temperature with the increase of sintering temperature. The TI-M measured at different AC frequencies was smaller than that measured at dC condition, which implied that the I-M phase transition was suppressed at AC frequencies. The resistivity mea- sured at high AC frequencies was larger than that measured at low AC frequencies, which could be attributed to the change of the magnetic penetration depth （6）. However, the room-temperature AC-magnetoresistance （Mr） at low frequencies was much larger than that at high frequencies and room-temperature dC-Mr. These findings demon- strate that reducing the AC frequency is an effective way for enhancing the room-temperature Mr, which can be used to promote the efficiency of magnetoresistive sensor.

KAGrA is a newly built gravitational wave observatory, a laser interferometer with a 3 km arm length, located in Kamioka, Gifu prefecture, Japan. In this article, we describe the KAGrA data management system, i.e., recording of data, transfer from the KAGrA experiment site to computing resources, as well as data distribution to tier sites, including international sites in Taiwan and Korea. The amount of KAGrA data exceeded 1.0 PiB and increased by about 1.5 TB per day during operation in 2020. Our system has succeeded in data management, and has achieved performance that can withstand observations after 2023, that is, a transfer rate of 20 MB s-1or more and file storage of sufficient capacity for petabyte class. We also discuss the sharing of data between the global gravitational-wave detector network with other experiments, namely LIGO and Virgo. The latency, which consists of calculation of calibrated strain data and transfer time within the global network, is very important from the view of multi-messenger astronomy using gravitational waves. real-time calbrated data delivered from the KAGrA detector site and other detectors to our computing system arrive with about 4–15 seconds of latency. These latencies are sufficiently short compared to the time taken for gravitational wave event search computations. We also established a high-latency exchange of offline calibrated data that was aggregated with a better accuracy compared with real-time data.

Topological insulators are insulating in the bulkbut have metallic surface states. Its unique physicochemicalproperties can find numerous applications in electronics,spintronics, photonics, the energy sciences, and thesignal control of transportation. We report an experimentalapproach to synthesize the high-quality single crystal oftopological insulator Bi2Te3 by using self-flux method. Weobtained the optimal preparation conditions by adjustingthe parameters of heat treatment, and successfully preparedthe single-crystal Bi2Te3 sample. The as-grown sampleshave a surface with bright metallic luster and are soft andfragile. Furthermore, Bi2Te3 has the obvious layer structurefrom SEM results. The data of X-ray diffraction andscanning electron microscope show that Bi2Te3 singlecrystal grows along the c-axis with the order of Te（1）–Bi–Te（2）–Bi–Te（1） and crystallizes in the hexagonal systemwith space group of r/3 m. The q–T curve shows that qdecreases with temperature, showing metallic behaviorover the whole temperature range.

A multi-scale point of view on the structure–property relationships of A15 superconductors

Journal of Modern Transportation 2014年第2期22卷 122-126页

作者： Yanlong ding Min Pan Shuiquan deng Yong Zhao Key Laboratory of Magnetic Levitation Technologies and Maglev Trains Ministry of Education of China and Superconductivity and New Energy R&D Center Southwest Jiaotong University

Nb3Sn and other A15 members have been widely applied in nuclear power, nuclear magnetic resonance, and high-energy particle accelerators for their high critical current density （Jc） and upper critical field （Bc2）. There have been comprehensive and intensive studies on the applications, the fundamental lattice dynamic and electronic properties, etc., of A15 superconductors. Various reviews on the preparations, structures, and properties have already been written in the last few years. Nevertheless, on account of the large amount of existing facts and views, a coherent view on the relations between the structures and properties has not appeared to unify the facts. This article sketches a multi-scale point of view on the relations between the multi- scale structures and the corresponding properties.
