Robust URL Phishing Detection Based on Deep Learning
( Abdullah Al-alyan ),( Saad Al-ahmadi ) 한국인터넷정보학회 2020 KSII Transactions on Internet and Information Syst Vol.14 No.7
Phishing websites can have devastating effects on governmental, financial, and social services, as well as on individual privacy. Currently, many phishing detection solutions are evaluated using small datasets and, thus, are prone to sampling issues, such as representing legitimate websites by only high-ranking websites, which could make their evaluation less relevant in practice. Phishing detection solutions which depend only on the URL are attractive, as they can be used in limited systems, such as with firewalls. In this paper, we present a URL-only phishing detection solution based on a convolutional neural network (CNN) model. The proposed CNN takes the URL as the input, rather than using predetermined features such as URL length. For training and evaluation, we have collected over two million URLs in a massive URL phishing detection (MUPD) dataset. We split MUPD into training, validation and testing datasets. The proposed CNN achieves approximately 96% accuracy on the testing dataset; this accuracy is achieved with URL schemes (such as HTTP and HTTPS) removed from the URL. Our proposed solution achieved better accuracy compared to an existing state-of-the-art URL-only model on a published dataset. Finally, the results of our experiment suggest keeping the CNN up-to-date for better results in practice.

Background: To evaluate the perception of cancer patients toward treatment services and influencing factors and to inquire about the use of complementary alternative medicine (CAM). Materials and Methods: Information was obtained through pre-tested structured questionnaires completed by cancer patients during treatment at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Results: Of 242 patients, 137 (64.6%) accepted to enter this study. Most were Saudi (n=93, 68%), female (n=80, 58%), educated at university (n=71, 52%), married (n=97, 72%) and with breast cancer (n=36, 26%). One-hundred (73%) patients were satisfied with the services provided; 61% were Saudi. Ninety-four (68%) respondents were satisfied with the explanation of their cancer. Twenty-eight (21.6%) patients received CAM, of them 54.0% received herbal followed by rakia (21.0%), nutritional supplements/vitamins (7.0%) and Zamam water (18.0%), with significant differences among them (p =0.004). Seven (5%) patients believed this therapy could be used alone; 34 (25%) patients believed it could be used with other treatments, regardless of whether they themselves used this therapy. Fifty-three (53%) satisfied patients felt they received enough support; 31 (58%) patients received support from family and friends; 22 (41.6%) patients received support from the health-care team. Patients who received information about their disease from their physicians and those who felt they had enough support were more satisfied. The patients who took alternative treatment were older age, mostly female and highly educated but values did not reach significance. Conclusions: We stress enhancing the educational and supportive aspects of cancer-patient services to improve their treatment satisfaction and emphasize the need for increasing the educational and awareness programs offered to these patients.

The aim of the present study was to investigate the antihyperglycemic and protective potential of crocin, a pharmacologically active constituent of Crocus sativus L., in streptozotocin-induced diabetic rats. Rats were administered crocin intraperitoneally at doses of 15, 30, and 60 mg/kg of body weight for 6 weeks. The levels of thiobarbituric acid reactive substance (TBARS) and total thiol (SH) groups were measured in the liver and kidney at the end of 6 weeks. Under our experimental conditions, crocin at a dose of 60 mg/kg was found to significantly reduce the blood glucose level in diabetic animals. In addition, there was a significant increase in TBARS levels and decreased total thiol concentrations in the liver and kidney of diabetic animals. Crocin, at doses of 30 and 60 mg/kg, appears to exert an antioxidative activity demonstrated by a lowering of lipid peroxidation levels in these organs. In conclusion, our findings suggest that crocin has the hypoglycemic and antioxidative properties in streptozotocin-induced diabetes and it may be useful in the management of diabetic patients

Biomass Partitioning during the Life Cycle of Saffron (Crocus sativus L.) Using Regression Models
Mohammad Ali Behdani,Majid Jami Al-Ahmadi,Hamid-Reza Fallahi 한국작물학회 2016 Journal of crop science and biotechnology Vol.19 No.1
In this study saffron biomass partitioning was investigated in the research station of the Saffron Research Group, University of Birjand, Iran during 2009 - 2010. Plant sampling was done 25 times during the crop growth cycle. In each sampling date, the amounts of corm dry weight, root dry weight, root length, leaf dry weight, leaf area, bud number, bud dry weight (nodes on the surface of the corm), and flower weight were measured. Finally, different regression models were tested for predicting biomass partitioning in saffron. The cubic polynomial model was found to be the best for predicting biomass changes in most saffron organs (R2 = ~74%). Total corm dry weight showed a decreasing trend up to the 120th day of plant growth and then increased until the end of the life cycle (mid-May). However, different trends were observed for root and leaf dry weights. Root and leaf dry weight increased up to the 120th and 150th day of the plant growth cycle, respectively, followed then by decreasing trends. Therefore, in the early growing season, leaves and root systems were developed using mother corms reservoirs, but at the end of the growth cycle replacement corms were grown by translocation of reservoirs from other saffron organs. In addition, the number and dry weight of buds had increasing trends during 160 days of measurement from the beginning of the growing season. The total length of roots and leaf area increased up to the middle of the growth cycle (Feb. 10) and then decreased. Moreover, saffron flower yield showed a rapid increasing trend in the first phase of the flowering period and then declined with a slower trend during the second flowering phase.

Acute respiratory distress syndrome (ARDS) is commonly found in critically ill patients with coronavirus disease 2019 (COVID-19). As a non-pharmacological treatment of complementary and alternative medicine (CAM), cupping has been clinically used for respiratory symptoms. We sequentially identified a series of patients with COVID-19 with ARDS who were admitted to the intensive care unit (ICU). Warm cupping of the posterior thorax was performed for seven days. We collected longitudinal severity scores on cough, breathlessness, chest tightness, type of oxygen therapy, and oxygen saturation (SpO 2 ). We hereby report the changes in the severity scores in a series of eight patients who received 21 sessions of cupping in addition to conventional treatments. All patients reported improvement in symptom scores that was matched by an increase in SpO 2 by as much as 3.16%. All patients were discharged and did not require the use of a mechanical ventilator. The results suggest that combining cupping with conventional treatment may provide a good prognosis for patients with COVID-19 with ARDS.
