usury is prohibited in islam and other divine religions. however, the financial system which is common in today's world, especially in west, is founded on the basis of usury. in effect, it is the features present in usurious loans that seduce uncommitted capitalists into preferring this kind of contract to other methods of investment. as a matter of fact, such loans need not be supervised ...

Large-scale rumor spreading could pose severe social and economic damages. The emergence of online social networks along with the new media can even make rumor spreading more severe. Effective control of rumor spreading is of theoretical and practical significance. This paper takes the first step to understand how the blockchain technology can help limit the spread of rumors. Specifically, we d...

Data continuously gathered monitoring the spreading of COVID-19 pandemic form an unbounded flow data. Accurately forecasting if infections will increase or decrease has a high impact, but it is challenging because spreads and contracts periodically. Technically, data said to be imbalanced subject concept drifts signs decrements are minority class during periods, while they become majority in co...

A management framework has been successfully utilized at Imperial College London in the United Kingdom to improve the process for developing and managing university-industry research collaborations. The framework has been part of a systematic approach to increase the level of research contracts from industrial sources, to strengthen the university’s academic base, and to diversify the provision...

Spreading and decay rates of several synthetic jets are experimentally measured up to 70–100 diameters (d) away from the orifice. It is found that, consistent with previous studies, after 10d–15d from the nozzle a synthetic jet displays a self-similar velocity profile together with enhanced spreading and decay behaviors than a continuous jet. However, this enhancement does not persist throughou...

Isolated rat hepatocytes bind to synthetic flat polyacrylamide matrices containing covalently attached galactose residues in a sugar-specific and concentration-dependent manner. Cell binding is mediated by the asialoglycoprotein receptor and occurs as a threshold response at or above a critical concentration of sugar in the matrix. Hepatocytes in the presence or absence of serum were able to sp...

Using network-based information to facilitate information spreading is an essential task for spreading dynamics in complex networks. Focusing on degree correlated networks, we propose a preferential contact strategy based on the local network structure and local informed density to promote the information spreading. During the spreading process, an informed node will preferentially select a con...
