DNA extraction represents a significant bottleneck in nucleic acid analysis. In this study, hydrophobic magnetic ionic liquids (MILs) were synthesized and employed as solvents for the rapid and efficient extraction of DNA from aqueous solution. The DNA-enriched microdroplets were manipulated by application of a magnetic field. The three MILs examined in this study exhibited unique DNA extractio...
The photocatalytic reduction of Cr(VI) is investigated over iron(III)-based metal-organic frameworks (MOFs) structured as MIL-88B. It is found that MIL-88B (Fe) MOFs, containing Fe3-μ3-oxo clusters, can be used as photocatalyst for the reduction of Cr(VI) under visible light irradiation, which is due to the direct excitation of Fe3-μ3-oxo clusters. The amine-functionalized MIL-88B (Fe) MOFs (de...
MIL-STD-1553 is a military standard that defines the physical and logical layers, and a command/response time division multiplexing of a communication bus used in military and aerospace avionic platforms for more than 40 years. As a legacy platform, MIL-STD-1553 was designed for high level of fault tolerance while less attention was taken with regard to security. Recent studies already addresse...
We present a comprehensive study of the use of generative modeling approaches for Multiple-Instance Learning (MIL) problems. In MIL a learner receives training instances grouped together into bags with labels for the bags only (which might not be correct for the comprised instances). Our work was motivated by the task of facilitating the diagnosis of neuromuscular disorders using sets of motor ...
سه چارچوب فلز-آلی (mof) نانو متخلخل از آهن (iii) با 2-آمینوترفتالیک اسید و ترفتالیک اسید، (fe-mil-101-nh2) (1) و (fe-mil-53) (2) و (fe-mil-53-nh2) (3)، در چارچوب فلز-آلی نانو متخلخل از کروم (iii) با ترفتالیک اسید، (cr-mil-53) (4) و (cr-mil-101) (5)، یک چارچوب فلز-آلی نانو متخلخل از منگنز (ii) با 5،3،1 بنزن تری کربوکسیلیک اسید h2o، {(ch3)2 nh2} {mn3(btc) (hcoo)4 (h2o)} (6)، به روش سالووترمال و ی...
در این تحقیق، شبکه¬های فلزی-آلی به سبب خواص ویژه¬ای که دارند به¬عنوان یک بستر مناسب به¬کار گرفته شدند. شبکه¬ی فلزی-آلی کروم ترفتالات mil-101 با مساحت سطح m2/g4100 و دارای سایت¬های غیراشباع فلزی با روش هیدروترمال تهیه شد. سپس به¬طور مجزا با لیگاندهای دی¬اتیلن¬تری¬آمین و 2-آمینومتیل¬پیریدین عامل¬دار گردید. کمپلکس وانادیل استیل استونات به¬وسیله¬ی این آمین¬ها بر روی mil-101 تثبیت شد. این کاتالیزو...
Considering the multiple instance learning(MIL) in classification problem, a novel multiple instance twin support vector machines(MI-TWSVM) method is proposed. For linear classification, unlike other maximum margin SVM-based MIL methods, the proposed approach leads to two non-parallel hyperplanes. The non-linear classification via kernels is also studied. Preliminary experimental results on pub...
In this study, we reported millepachine (MIL), a novel chalcone compound for the first time isolated from Millettia pachycarpa Benth (Leguminosae), induced cell cycle arrest and apoptosis in human hepatocarcinoma cells in vitro and in vivo. In in vitro screening experiments, MIL showed strong antiproliferation activity in several human cancer cell lines, especially in HepG2 cells with an IC50 o...
MIL-53-Cu has been synthesized hydrothermally and has been used for the first time for gas separation. MIL-53-Cu shows adsorption capacities of 8.1, 0.7 and 0.5 m.mol/g, respectively, for CH4, CO2 and H2 at 30 bar and 298 K. The high CH4 adsorption capacity of MIL-53-Cu maybe attributed to the high pore volume and large number of open metal sites....
Many computer aided diagnosis (CAD) problems can be best modelled as a multiple-instance learning (MIL) problem with unbalanced data: i.e. , the training data typically consists of a few positive bags, and a very large number of negative instances. Existing MIL algorithms are much too computationally expensive for these datasets. We describe CH, a framework for learning a Convex Hull representa...
