Solar insecticidal lamps(SIL) can effectively control pests and reduce the use of pesticides. Combining SIL and Internet of Things(IoT) has formed a new type of agricultural IoT,known as SIL-IoT, which can improve the effectiveness of migratory phototropic pest control. However, since the SIL is connected to the Internet, it is vulnerable to various security issues.These issues can lead to serious consequences, such as tampering with the parameters of SIL, illegally starting and stopping SIL,etc. In this paper, we describe the overall security requirements of SIL-IoT and present an extensive survey of security and privacy solutions for SIL-IoT. We investigate the background and logical architecture of SIL-IoT, discuss SIL-IoT security scenarios, and analyze potential attacks. Starting from the security requirements of SIL-IoT we divide them into six categories, namely privacy, authentication, confidentiality, access control, availability,and integrity. Next, we describe the SIL-IoT privacy and security solutions, as well as the blockchain-based solutions. Based on the current survey, we finally discuss the challenges and future research directions of SIL-IoT.

Efficient privacy-preserving federated learning under dishonest-majority setting

Science China(Information Sciences) 2024年第5期67卷 323-324页

Federated learning(FL) is an emerging distributed learning paradigm that solves the problem of isolated data by jointly learning the global model through distributed clients.However, recent studies have shown that FL may not always guarantee sufficient privacy preservation, this is mainly because the model parameters(e.g., weights or gradients)may leak sensitive information to malicious adversaries.

Comparing the effects of three decoctions for coronavirus disease 2019 on severe acute respiratory syndrome coronavirus 2-related toll-like receptors-mediated inflammations

OBJECTIVE:To compare the anti-inflammatory effects of three decoctions for coronavirus disease 2019(COVID-19)[Qingfei Paidu Tang(清肺排毒汤),QF;Huashi Baidu Fang(化湿败毒方),HS;Xuanfei Baidu Fang(宣肺败毒方),XF]in parallelly experimental models by using severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)-related toll-like receptors(TLRs)ligands and its spike(S)protein as stimulators.METHODS:RAW264.7 macrophages were used to investigate the effects of three decoctions on the inflammations induced by R848,poly(I:C),lipopolysaccharide(LPS),as well as SARS-CoV-2 S protein,in vitro.Mouse endotoxemia model was used for evaluating their anti-inflammatory actions in vivo.The levels of monocyte chemoattractant protein-1(MCP-1),interleukin-6(IL-6),tumor necrosis factorα(TNF-α),and interferon-β(IFN-β)were determined by enzyme-linked immunosorbent assay.RESULTS:Three decoctions could decrease supernatant IL-6,MCP-1,nitric oxide(NO)and TNF-αto varying degrees in activated macrophages.Meanwhile,they did not increase the level of antiviral cytokine IFN-βinduced by TLR3 and TLR4 ligands,but rather suppressed it,suggesting that externally administrated type I interferons(IFN-Is)may be needed for the severe COVID-19 cases characterized by deficient IFN-Is.In mouse endotoxemia model,all three decoctions could suppress serum pro-inflammatory cytokines,but only QF could relieve hypothermia and antagonize diarrhea.CONCLUSIONS:Collectively,our study compared,for the first time,the effects of three decoctions on SARSCoV-2-related TLRs-mediated inflammations.In vitro,three decoctions exert similar suppressive effects on inflammatory cytokines induced by SARS-CoV-2-related TLRs ligands,as well as S protein.In vivo,QF possesses the strongest effects compared with HS and XF.These findings may provide not only experimental basis for the clinical use of three decoctions,but also a rationale for the combination therapy with IFN-Is.

All solid-state batteries(ASSBs)are the holy grails of rechargeable batteries,where extensive searches are ongoing in the pursuit of ideal solid-state electrolytes.Nevertheless,there is still a long way off to the satisfactorily high(enough)ionic conductivity,long-term stability and especially being able to form compatible interfaces with the solid electrodes.Herein,we have explored ionic transport behavior and high mobility in the sub-nano pore networks in the framework structures.Macroscopically,the frameworked electrolyte behaves as a solid,and however in the(sub)-nano scales,the very limited number of solvent molecules in confinement makes them completely different from that in liquid electrolyte.Differentiated from a liquid-electrolyte counterpart,the interactions between the mobile ions and surrounding molecules are subject to dramatic changes,leading to a high ionic conductivity at room temperature with a low activation energy.li+ions in the sub-nano cages of the network structure are highly mobile and diffuse rather independently,where the rate-limiting step of ions crossing cages is driven by the local concentration gradient and the electrostatic interactions between li^(+)ions.This new class of frameworked electrolytes(FEs)with both high ionic conductivity and desirable interface with solid electrodes are demonstrated to work with li-ion batteries,where the ASSB with liFePO_(4)shows a highly stable electrochemical performance of over 450 cycles at 2℃ at room temperature,with an almost negligible capacity fade of 0.03‰ each cycle.In addition,the FE shows outstanding flexibility and anti-flammability,which are among the key requirements of large-scale applications.

由于高校宿舍人员高度密集,一旦发生火灾其极易造成严重后果,因此高校宿舍火灾问题亟待重视。为合理评估该风险,首先,借助文献从人、物、环境、管理四方面建立评价指标体系及评价量表;其次,运用合作博弈法将主观赋权结果和客观赋权结果相结合以对评价指标进行组合赋权;随后,将指标权重集转换成各指标轴夹角并计算各指标取值;最后,将经火灾风险雷达图平均周长与同面积圆周长之比为短板系数进行修正的雷达图平均面积作为评价特征量建立高校宿舍火灾风险评价方法。该方法可避免人为赋权的主观性且能以图形形式直观显示出风险管控环节中的薄弱环节。最后以某一实例验证了该评价方法的有效可行性,可为高校宿舍火灾风险评价提供新的思路。

Dear editor,Site specific recombinases have been widely used for genome engineering in cardiovascular research (Fu et al., 2024;Huang et al., 2023; Xue et al., 2022). In particular, Cre is the most broadly used recombinase for cell type-specific lineage tracing and gene manipulation in mammals. For smooth muscle cell (SMC)-specific targeting, several SMC promoters including Myh11 (smooth muscle myosin heavy chain), Acta2 (smooth muscle a-2actin), and SM22a (Tagln) have been used to drive Cre or CreER.

乔治·伯纳德·萧是继莎士比亚之后最负盛名的英国剧作家,他继承和发扬了亨利克·易卜生开创的真实反映社会现实、揭露社会痼疾的优良传统,创作了大量批判现实的社会问题剧,《卖花女》便是其中的优秀作品之一。在法国哲学家米歇尔·福柯的权力理论视角下,资本主义社会中的底层女性被边缘化、他者化、异化。《卖花女》中的女主人公伊莉莎经历了权力压迫下的身体和话语的双重规训,被消解了行动和话语的自主支配权。然而,反抗与规训是共生的,伊莉莎最终顿悟觉醒,勇敢地反抗资产阶级的权力控制和压迫,实现了身体和精神的双重解放。

完善电动汽车(EV)主动参与充放电双向互动调频的激励机制,综合考虑EV充放电行为在能量-调频市场中的多阶段交互影响,有利于准确评估聚合商参与电力市场的收益。提出了EV聚合商参与多品种市场的多阶段运营策略,以实现聚合商的运营收益最大化。基于充电行为特征的统计数据,建立单体EV的功率及能量响应边界,并考虑用户参与充电和放电控制的差异性,结合用户自身偏好、电池损耗,提出EV集群的充放电激励机制,并在此基础上建立EV集群功率及能量的响应边界约束。基于EV充放电调节控制的时序性和多阶段市场的调频需求,建立考虑多阶段时序交互的多品种市场运营收益优化模型。结合PJM市场的运营案例,验证所提充放电激励机制和运营策略的有效性,结果表明其能在保障用户充电需求的基础上,有效提升聚合商参与能量-调频市场的收益。

本研究成功构建了具有切割DNA能力的双金属枝状大孔金属有机框架(MOFs;HMUiO-66(Zr/Ce)),并将其用于高效破坏生物膜并抑制细菌生长.通过改变Zr/Ce的投料比,可在0-69%的范围内精确调控Zr/Ce的引入量,并控制其粒径在1μm-150 nm之间.HMUiO-66(Zr/Ce)具有独特的化学和热稳定性,开放的大孔结构和可接近的Lewis酸活性位点,表现出模拟DNA酶活性.双金属MOFs中丰富的Zr-OH位点能有效地捕获核酸,而相邻的Ce-OH基团对磷氧键形成亲核攻击,协同放大DNA的水解速率,使得开发的HMUiO-66(Zr/Ce)能够作为切割细胞外DNA和清除细菌生物膜的纳米药物.在此基础上,我们设计了一种仿生HMUiO-66(Zr/Ce)/PVDF膜,该生物膜可抑制细菌粘附和定植,在抗菌治疗和医疗器械中具有广阔的应用前景.

为研究不同絮凝剂对钻井泥浆的絮凝效果,采用破胶絮凝的方法对含水率高、成分复杂的山西某煤层气废弃钻井泥浆进行处理,研究不同破胶絮凝剂和助凝剂种类及投加量等因素对废弃钻井泥浆处理效果的影响,并利用扫描电子显微镜(SEM)探究了破胶助凝的机理。结果表明:2000 mg/L的硫酸铝破胶絮凝效果最优,10 mg/L的非离子聚丙烯酰胺(NPAM)与其协同处理效果最佳,处理后的液相色度、COD_(Cr)、悬浮物含量和泥饼含水率分别为20倍、61.98、32.50 mg/L、78.64%;硫酸铝的电中和作用可以和NPAM桥联网捕作用产生良好的协同效果,能够显著加快泥浆中颗粒物的絮凝沉降,增大絮体体积和疏松程度,从而降低液相污染物含量和泥饼含水率。研究结果可为废钻井泥浆的絮凝处理提供一定的参考和理论依据。
