Online reviews have become a valuable resource for decision making. However, its usefulness brings forth a curse ‒ deceptive opinion spam. In recent years, fake review detection has attracted significant attention. However, most review sites still do not publicly filter fake reviews. Yelp is an exception which has been filtering reviews over the past few years. However, Yelp’s algorithm is trad...

Recently introduced connections between quantum codes and Narain CFTs provide a simple ansatz to express modular-invariant function $Z(\tau,\bar \tau)$ in terms of multivariate polynomial satisfying certain additional properties. These properties include algebraic identities, which ensure modular invariance \tau)$, positivity integrality coefficients, imply the $\mathfrak{u}(1)^n \times \mathfr...

On April 10 economist John R. Lott, Jr., formerly of the American Enterprise Institute, filed a defamation lawsuit against economist Steven D. Levitt of the University of Chicago and HarperCollins, the publisher of Levitt's 2005 book, Freakonomics. At issue is what Levitt meant when he wrote that scholars could not "replicate" Lott's results, referring to Lott's 1998 book, More Guns, Less Crime...

The main objective of this project is fake currency detection using the image processing. Fake currency detection is a process of finding the forgery currency. After choose the image apply preprocessing. In pre-processing the image to be crop, smooth and adjust. Convert the image into gray color. After conversion apply the image segmentation. The features are extracting and reduce. Finally comp...

In Nigeria, it was reported in 2009 that 84 children were killed as a result of toxic chemicals that were laced with teething medications for babies [1]. In 2012, Angolan custom agents busted counterfeiters importing what turned out to be the largest fake medicine imports in history, when containers shipped from China to Luanda were filled with over 1.4 million packets of fake antimalarial drug...

In this paper we consider Property (FA) for lattices in SU(2, 1). First, we prove that SU(2, 1;O3) has Property (FA). We then prove that the arithmetic lattices in SU(2, 1) of second type arising from congruence subgroups studied by Rapoport–Zink and Rogawski cannot split as a nontrivial free product with amalgamation; one such example is Mumford’s fake projective plane. In fact, we prove that ...

Recently, there is a rapid and wide increase in fake news, defined as provably incorrect information spread with the goal of fraud. The this type misinformation severe danger to social cohesiveness well-being since it increases political polarisation people’s distrust their leaders. Thus, news phenomenon that having significant impact on our lives, particularly politics. This paper proposes nov...
