AIM: To compare the anti-inflammatory effects of intense pulsed light(IPL) with tobramycin/dexamethasone plus warm compress through clinical signs and cytokines in ***: Eighty-two patients with dry eye disease(DED) associated meibomian gland dysfunction(MGD) were divided into two groups. Group A was treated with IPL, and Group B was treated with tobramycin/dexamethasone plus warm compress. Ocular Surface Disease Index(OSDI), tear film breakup time(TBUT), corneal fluorescein staining(CFS), meibomian gland expressibility(MGE), meibum quality, gland dropout and tear cytokine levels were evaluated before treatment, 1 wk and 1 mo after treatment. RESULTS: TBUT in Group A was higher(P=0.035), and MGE score was lower than Group B at 1 mo(P=0.001). The changes of interleukin(IL)-17 A and IL-1β levels in tears were lower in Group A compared with that in Group B at 1 wk after treatment(P=0.05, P=0.005).CONCLUSION: Treatment with IPL can improve TBUT and MGE and downregulate levels of IL-17 A and IL-1β in tears of patients with DED associated MGD better than treatment with tobramycin/dexamethasone plus warm compress in one-month treatment period.

In scenarios where a large amount of data needs to be learned, incremental learning can make full use of old knowledge, significantly reduce the computational cost of the overall learning process, and maintain high performance. In this paper, taking the MaxCut problem as our example, we introduce the idea of incremental learning into quantum computing, and propose a Quantum Proactive Incremental Learning algorithm(QPIL). Instead of a one-off training of quantum circuit, QPIL contains a multi-phase training on gradually-increased subgraphs of all vertices, proactively reducing large-scale problems to smaller ones to solve in steps, providing an efficient solution for MaxCut. Specifically, some vertices and corresponding edges are randomly selected for training to obtain optimized parameters of the quantum circuit at first. Then, in each incremental phase, the remaining vertices and corresponding edges are gradually added and the parameters obtained from the previous phase are reused in the parameter initialization of the current phase. We perform experiments on 120 different small-scale graphs, and it shows that QPIL performs superior to prevalent quantum and classical baselines in terms of approximation ratio(AR), time cost, anti-forgetting, and solving stability. In particular, QPIL's AR surpasses 20% of mainstream quantum baselines, and the time cost is less than 1/5 of them. The idea of QPIL is expected to inspire efficient and high-quality solutions in large-scale Max Cut and other combinatorial optimization problems.

隧道在交通工程中被越来越广泛应用。结合京沪高速济南连接线浆水泉隧道全断面开挖的施工过程,阐述了楔形掏槽爆破技术的应用。楔形掏槽是斜眼掏槽中较易掌握的掏槽方式,其适用性较强,施工进尺较大,目前凡手持风钻进行爆破开挖的爆破作业,大多采用此方式。楔形掏槽一般布置在开挖断面的中部偏下,但是对于扁平形大断面隧道,采用中部进行掏槽,受断面扁平形状的影响,掏槽后槽腔距开挖轮廓线上部与两侧的厚度相差较大,辅助孔爆破时两侧较厚夹制作用明显。这就需要对传统的楔形掏槽进行优化,文章阐述了大断面扁平隧道中应用的一种双三级楔形掏槽,分析新方式的利弊,对类似工程的掏槽爆破提供参考。

Zeolite nanosheets with a short b-axis thickness are highly desirable in lots of catalytic reactions due to their reduced diffusion resistance. Nevertheless, conventional synthesis methods usually require expensive structure-directing agents(SDAs), pricey raw materials, and eco-unfriendly fluorine-containing additives. Here, we contributed a cost-effective and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silicalite-1(Sil-1) seed suspension and urea cooperative strategy, only with inexpensive colloidal silica as the Si source. Our approach was effective for synthesizing both Sil-1 and aluminum-containing ZSM-5 nanosheets. By optimizing key synthesis parameters,including seed aging time, seed quantity, and urea concentration, we achieved precise control over the crystal face aspect ratio and b-axis thickness. We also revealed a non-classical oriented nanosheet growth mechanism, where Sil-1 seeds induced the formation of quasi-ordered precursor particles, and the(010)crystal planes of these particles facilitated urea adsorption, thereby promoting c-axis-oriented *** obtained ZSM-5 nanosheets exhibited exceptional catalytic performance in the benzene alkylation with ethanol, maintaining stability for over 500 h, which is 5 times longer than traditional ZSM-5 catalysts. Furthermore, large-scale production of ZSM-5 nanosheets was successfully carried out in a 3 L highpressure autoclave, yielding samples consistent with those from laboratory-scale synthesis. This work marks a significant step forward in the sustainable and efficient production of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applicability in catalysis.
