随着人口爆炸、工业和高新产业发展的持续,工厂和居民对清洁用水需求日益增加,水雾收集器件不断涌现,而现有水雾收集器件多采用飞秒激光刻蚀等方式达到符合要求的浸润性表面,对设备要求较高。本文基于简便的室温自发胶凝作用,温和构建凝胶聚合物基质,通过引入反应组分以控制胶凝成形期间的微观形貌与表面能分布,经室温修饰形成超疏水聚合物复合材料。以针织物为基底、摩擦为手段构制Janus针织物涂层,利用其润湿不对称性实现单向导湿,进而在捕雾集水的同时减缓水蒸发以提升应用效率,达到低成本且高效的雾收集。

AIIorejection remains an obstacle for successful organ transplantation. Although different types of immunosuppressive agents are effective for controlling rejection and prolonging graft survival, drug treatment is limited because of side effects and toxicity. Therefore, it is necessary and urgent to identify new candidate drugs for inducing allotolerance. Recently, it has been reported that bacterial flagellin induces the immunosuppressive activity of regulatory T cells （Tregs） in humans in vitro. In the present study, we analyzed the effects of recombinant flagellin （rFliC） on allograft survival and explored the underlying mechanisms associated with the activation of recipient Tregs in a murine skin allotransplantation model. The results showed that rFliC administration （3 mg/kg, once per day for 3 days, i.p.） prolonged allograft survival （mean survival time： 18.4--.1.1 days） compared to the control group （10___0.7 days, P〈O.01）. Additionally, higher positive expression of Toll-like receptor 5 （TLR5） was detected within the allograft administered with rFliC. The frequency of CD4＋CD25＋Foxp3＋ Tregs; the expression of Treg-related factors TLR5, Foxp3, TGF-I^I and IL-IO; and the proliferation and suppression of Tregs were increased following rFliC administration compared to the control. Moreover, the increased expression of tolerance-related molecules and the proliferation of Tregs induced by rFliC were attenuated by an anti-TLR5 blocking antibody both in vivo and in vitro. In conclusion, rFliC administration prolongs the survival of allografts, which is associated with the activation of recipient Tregs in a TLR5-dependent manner, rFliC may be a new candidate for anti-allorejection therapy.

Background Suboptimal myocardial reperfusion is common in patients with ST-segment elevation myocardial infarction （STEMI） undergoing primary percutaneous coronary intervention （PPCI）. Furthermore, it results in increased infarct size and mortality rates. We performed a meta-analysis to evaluate the role of aspiration thrombectomy （AT） combined with intracoronary administration of glycoprotein IIb/IIIa inhibitors （GPI） in the improvement of myocardial reperfusion and clinical outcomes. Methods PubMed, Embase, Web of Science, and CENTRAL databases were searched for randomized controlled trials （RCTs） investigating combined AT and intracoronary GPI treatment versus AT alone. Outcomes of interest were thrombolysis in myocardial infarction myocardial perfusion grade （TMPG）, infarct size （IS） assessed by cardiac magnetic resonance imaging, left ventricular ejection fraction （LVEF）, major adverse cardiac events （MACE） at short-term （〈 1 month） and long-term （6-12 months） follow-up, and bleeding complications during the hospital stay. Results Eight trials involving 923 patients were included. Compared with AT alone, combined AT and intracoronary GPI significantly increased TMPG 3 flow （RR： 1.15, 95% CI： 1.04 to 1.26）, reduced IS [mean difference （MD）： -3.46, 95% CI： -5.18 to -1.73], and improved LVEF （MD： 1.44, 95% CI： 0.54 to 2.33）. Furthermore, GPI use decreased the risk of MACE at long-term follow-up （RR： 0.60, 95% CI： 0.37 to 0.98）. There was no significant difference between the two groups in the incidence of minor and major bleeding complications. Conclusions Our findings showed that compared with AT alone, combined AT and intracoronary GPI treatment resulted in improved myocardial reperfusion, better cardiac function, and MACE-free survival benefits at the long-term follow-up for patients with STEMI undergoing PPCI.

This paper is devoted to investigating the weighted LP-mapping properties of oscillation and variation operators related to the families of singular integrals and their commutators in higher dimension. We establish the weighted type （p, p） estimates for 1 〈 p 〈 ∞ and the weighted weak type （1, 1） estimate for the oscillation and variation operators of singular integrals with kernels satisfying certain HSrmander type conditions, which contain the Riesz transforms, singular integrals with more general homogeneous kernels satisfying the Lipschitz conditions and the classical Dini＇s conditions as model examples. Meanwhile, we also obtain the weighted LP-boundeness for such operators associated to the family of commutators generated by the singular integrals above with BMO（Rd）-functions.

In this paper, we establish an estimate for the solutions of small-divisor equation of higher order with large variable coefficient. Then by formulating an infinite-dimensional KAM theorem which allows for multiple normal frequencies and unbounded perturbations, we prove that there are many periodic solutions for the coupled KdV equation subject to small Hamiltonian perturbations.

随着个人图像数量日益增加,云服务开始在图像存储方面发挥重要作用.然而,将图像上传到云端将会面临隐私威胁.传统的加密方案对图像进行简单加密就可以保护图像隐私,但它牺牲了图像内容的可用性.近年来,缩略图保留加密(thumbnail preserving encryption,TPE)被提出,通过加密后保持缩略图不变使云中图像在不被非法第三方肉眼识别的同时能对用户具有可用性.但是现有的TPE方案没有考虑到机器学习对图像的隐私威胁.基于此,提出了一种新的TPE方案,该方案在加密过程中从对抗深度学习模型识别图像这一全新的角度出发,提高了保护图像隐私信息的能力.实验表明,所提出的方案能够在图像对用户具有可用性的同时抵抗人类肉眼和深度神经网络识别图像.

We review our recent experimental realization and investigation of a spin orbit （SO） coupled Bose Einstein condensate （BEC） and quantum degenerate Fermi gas. By using two counter-propagathlg Ranlan lasers and controlling the different frequency of two R,aman lasers to engineer the atom light interaction, we first study the SO coupling in BEC. Then we study SO coupling in Fermi gas. We, observe the spin dephasing in spin dynamics and momentum distribution asymmetry of the equilibrium state as halhnarks of SO coupling in a Fermi gas. To clearly reveal the, property of SO coupling Fermi gas, we also study the momentmn-resolved radio-frequency spectroscopy which characterizes the energy momentum dispersion and spin composition of the quantum states. We observe the change of errmion surfaces in different helieity branches with different atomic density, which indicates that a Lifshitz transition of the Fermi surface topology change can be found by further cooling the system. At last, we study the momentum-resolved Raman spectroscopy of an ultracoht Fermi gas.
