Swarm based optimization algorithms are a collection of intelligent techniques in the field Artificial Intelligence (AI) were developed for simulating behavior animals. Over years ago, problems complexity increased means that it is very difficult basic mathematical approaches to obtain an optimum solution optimal time, this leads researchers develop various base on natural behaviors living bein...

Computerized Adaptive Testing (CAT) refers to an efficient and personalized test mode in online education, aiming accurately measure student proficiency level on the required subject/domain. The key component of CAT is "adaptive" question selection algorithm, which automatically selects best suited for based his/her current estimated proficiency, reducing length. Existing algorithms rely some m...

In this paper, we consider a platform of flying mobile edge computing (F-MEC), where unmanned aerial vehicles (UAVs) serve as equipment providing computation resource, and they enable task offloading from user (UE). We aim to minimize energy consumption all UEs via optimizing association, resource allocation the trajectory UAVs. To end, first propose Convex optimizAtion based Trajectory control...

BACKGROUND Complex antithrombotic therapy (CAT) prescribed to elderly patients increases the risk of gastrointestinal bleeding. We quantified upper (UGIE) and lower gastrointestinal (LGIE) events, transfusions, and hospitalizations in a national cohort of elderly veterans prescribed CAT. METHODS AND RESULTS Veterans ≥60 years of age prescribed anticoagulant-antiplatelet, aspirin (ASA)-antipla...

introduction: open-apex teeth with irreversible pulpitis require complex and difficult treatment. providing the right environment for apexogenesis and pulp protection is vital for their long term prognosis. the young pulp of open apex tooth, however, is better equipped against irritation and assault. the aim of this study was to evaluate pulp inflammation in open apex canine teeth of cats. mate...

enhancement of antioxidant capacity of plants by natural antioxidants obtained from medicinal plants can be a simple way to produce stress tolerant plants. zataria multiflora essential oil (zo) is one of the useful antioxidants with potent antioxidant activity. zo is insoluble in water and can be degraded by light, oxygen, and high temperature. incorporation of zo into poly vinyl alcohol (pva) ...

background : the visceral larva migrans (vlm) is a syndrome observed in human infection with helminth larval eggs such as the toxocara spp. that usually infects dogs and cats. among the risk factors involved in the occurrence of vlm, partic­ularly importance of these animal populations, an investigation was carried out for the presence of toxocara spp. eggs in public parks in the city of urmia,...

cats play crucial roles in the epidemiology of toxoplasmosis. in the present study, a total of 198companion cats of different ages were examined for serum antibodies against toxoplasma gondii byimmunochromatography assay and for oocyst presence in faeces by microscopic examination (flotationmethod) and immunochromatography assay. the cats were selected between referred cases to the veterinary h...

This study primarily addresses the development of dynamic, selective and economical metal–acid (bifunctional) catalysts for one-pot menthol production by citral hydrogenation. Specifically, various metals such as Pd, Pt, Ni, Cs Sn were doped over alumina support. Additionally, bifunctional composite also prepared with impregnation heteropoly acids Pd precursors Analytical techniques (e.g., BET,...
