Phishing threats， especially those sent via SMS (known as smishing)， are a big worry in the digital world. So better ways are needed to fight against phishing because cybercriminals keep changing their tactics. This study aims to make the online systems safer by using advanced technology called deep learning ， specifically a method called the AlexNet-LSTM algorithm， to sort out smishing messages effectively. Phishing vulnerability depends on different things such as age， gender， how much time someone spends online， and how stressed they are. In this study， deep learning is used to find SMS threats， and different types of text-based attacks are figured out by using the AlexNet-LSTM algorithm. To evaluate the superiority of this new method and how well it performs， it is compared with traditional methods such as logistic regression， random forest， and support vector machine. The results show a big improvement in accuracy， up to 99.6%， proving the efficacy of deep learning to make the online systems safer against various tricky attacks.

The next generation oflogic gate devices are expected to depend upon radically new technologies mainly due to the increasing difficulties and limitations of existing CMOS technology. MOSFET like CNFETs should ideally be the best devices to work with for high-performance VLS1. This paper presents results of a comprehensive comparative study of MOSFET-like carbon nanotube field effect transistors （CNFETs） technology based logic gate library for high-speed, low-power operation than conventional bulk CMOS libraries. It focuses on comparing four promising logic families namely： complementary-CMOS （C-CMOS）, transmission gate （TG）, complementary pass logic （CPL） and Domino logic （DL） styles are presented. Based on these logic styles, the proposed library of static and dynamic NAND-NOR logic gates, XOR, multiplexer and full adder functions are implemented efficiently and carefully analyzed with a test bench to measure propagation delay and power dissipation as a function of supply voltage. This analysis provides the right choice of logic style for low-power, high-speed applications. Proposed logic gates libraries are simulated using Synopsys HSPICE based on the standard 32 nm CNFET model. The simulation results demonstrate that, it is best to use C-CMOS logic style gates that are implemented in CNFET technology which are superior in performance compared to other logic styles, because of their low average powerdelay-product （PDP）. The analysis also demonstrates how the optimum supply voltage varies with logic styles in ultra-low power systems. The robustness of the proposed logic gate library is also compared with conventional and state-art of CMOS logic gate libraries.

A high throughput ultra pressure liquid chromatography-mass spectrometry （UPLC-MS/MS） method with good sensitivity and selectivity has been developed and validated for simultaneous quantification of esomeprazole, rabeprazole and levosulpiride in human plasma using lansoprazole as internal standard （IS）. The extraction method based on liquid-liquid extraction technique was used to extract the analytes and IS from of 50 μL of human plasma using methyl tert-butyl ether：ethyl acetate （80：20, v/v）, which offers a high recovery. Chromatographic separation of analytes and IS was achieved on a Hypersil gold C18 column using gradient mobile phase consisting of 2 mM ammonium formate/acetonitrile. The flow rate was set at 0.5 mL/min to elute all the analytes and IS within 1.00 min runtime. Detection of target compounds was performed on a triple quadruple mass spectrometer by multiple reaction monitoring （MRM） mode via positive electrospray ionization （ESI）. Method validation results demonstrated that the developed method has good precision and accuracy over the concentration ranges of 0.1-2000 ng/mL for each analyte. Stability of compounds was established in a battery of stability studies, i.e., bench top, autosampler, dry extract and long-term storage stability as well as freeze-thaw cycles. The validated method has been successfully applied to analyze human plasma samples for application in pharmaco- kinetic studies.

目的肾结石是一种常见的泌尿外科疾病,本研究主要评估了有毛白花苋根的水醇提取物(HAEAL)对乙二醇诱导的大鼠肾结石的防治作用。方法使用索氏提取器,将50 g阴干的有毛白花苋根粗研粉末,按照有机溶剂极性递增的顺序,依次通过石油醚(60-80℃)、氯仿和乙醇提取后浓缩。同时,对草药悬浮液的性质、颜色、气味和质地进行物理检测。肾结石体外评估通过成核试验、聚集试验和晶体生长试验进行。将30只成年雄性Wistar白化大鼠随机分为5组,每组6只。第一组为阴性对照组,不进行结石诱导并自由饮水28天;第二组为阳性对照组,口服0.75%乙二醇处理14天,并自由饮水28天;第三组为标准组,口服0.75%乙二醇处理14天,第15天至第28天予以750 mg/kg Cystone;第四组为低剂量HAEAL组,口服0.75%乙二醇处理14天,第15天至第28天给予400 mg/kg HAEAL,每天1mL;第五组为高剂量HAEAL组,口服0.75%乙二醇处理14天,第15天至第28天给予800 mg/kg HAEAL,每天1mL;之后进行尿液(尿量、pH值、外观、气味及浑浊度)检验和血清试验。第29天,对大鼠肾脏进行解剖,通过组织病理学检查,以确定肾实质的损伤程度。结果在室温下,悬浮液具有芳香气味,且稳定性良好,无浑浊现象。至第三天,悬浮液未出现颜色及气味的变化,说明该制剂的稳定性可达72小时。阳性对照组的大鼠体重减轻,表明有结石形成及饮水量改变。标准治疗组和HAEAL治疗组在接受治疗后,体重均恢复到正常水平,表明治疗效果良好。组织病理学检查结果显示,阴性对照组无明显病变,阳性对照组大鼠的肾实质区域出现炎症反应。与阳性对照组相比,HAEAL治疗组大鼠的尿量和尿成分如钙和草酸的排泄均有增加(P <0.01),且清除率也有所提高(P <0.05)。此外,HAEAL治疗组大鼠的尿液pH值显著升高。结论 HAEAL能减少肾结石形成,且具有利尿作用,可促进结石的排出。但对于如何提高悬浮液的稳定性,以制备更好的药物配方,仍需进一步的研究。
