We investigate an online optimal sensor transmission scheduling problem for remote state estimation. We consider the energy harvesting sensor, which can absorb external energy and use the energy to transmit the local state estimates to the remote estimator over an unreliable wireless channel. Furthermore, we consider that the sensor has two different transmission energy levels, where different energy levels correspond to different data reception ratios. Considering the trade-off between estimation performance and energy consumption, we hope to design an optimal transmission policy that minimizes the convex combination of the estimation error covariance and the energy for data transmission. We formulate the optimization problem as a Markov decision process, which can be solved by dynamic programming. Then, we introduce the concept of submodularity to prove that there is an optimal threshold policy on the error covariance, given sensor battery and collected energy. Eventually, simulations are given to illustrate the aforementioned results.

为了解上海青浦地区混群繁殖鹭类的活动规律以及夜宿地和觅食地利用的种间差异,本研究选择青浦地区3种鹭类优势种——池鹭(Ardeola bacchus)、白鹭(Egretta garzetta)和夜鹭(Nycticorax nycticorax)作为研究对象,于2018年6月和7月在青浦郊野公园捕捉鹭类并佩戴GPS-GSM追踪设备,截至2019年7月底,共获得了5只追踪时间在86~377天之间的活动信息(1只池鹭、2只白鹭和2只夜鹭).结果显示:这5只鹭鸟没有表现出明显的长距离迁徙,仅扩散到离巢区不远的范围,最远达淀山湖以南的沪浙交界处,活动范围的面积存在较大的种内和种间差异.池鹭与白鹭的活动节律相近,均为白天活动、夜晚休息,但栖息地利用具有明显差异,池鹭夜晚和白天的主要栖息地分别是林地和莲池水塘,白鹭夜晚和白天的主要栖息地分别是林地和农田.夜鹭多在夜间活动,但两只夜鹭个体在夜间的栖息地也存在很大不同.连续追踪一整年的白鹭个体的每日移动距离在冬季明显增加,这可能与冬季食物资源较少有关.本研究表明鹭类主要利用农田和莲池水塘等人工栖息地,适宜强度的农业活动可能并不影响鹭类的种群维持.

Background Although ^(32)P-glass microspheres (^(32)P-GMS) have been used ininternal radiotherapy for malignant tumors, it has been one of the key obstacles to improve theeffect of radiotherapy. We investigated the cellular and hypersensitive effect of combined use oflow dose of cisplatin and interstitial injection of ^(32)P-GMS on mouse solid tumor S180. MethodsThe mice with solid tumor S180 were randomly divided into four groups (controls, cisplatin therapy,^(32)P-GMS therapy and combination therapy). The specimens of the mice were sectioned two weeksafter treatment and weighed. The death rate of tumor cells and the inhibition rate of tumor werecalculated respectively. The cell cycle and apoptosis rate were evaluated with flow-cytometry. Theultrastructural changes of the four groups were observed by a transmission electron microscope. Thedata were analyzed by the chi-square test. Results The growth of tumor was slower in the combinationtherapy group than in the simple therapy groups by macrography. The inhibition rate and the deathrate of tumor cells of the combination therapy group were significantly higher than those of thecontrol group and the other two simple therapy groups ( P < 0. 05). More cell damages were displayedin the combination therapy group than in the other groups under the light and electronicmicroscope. Conclusion Low-dose cisplatin combined with interstitial injection of ^(32)P glassmicrospheres could be used as an effective hypersensitive regimen for the internal radiotherapy ofmouse solid tumor S180.
