Twitter can suffer from malicious tweets containing suspicious URLs for spam, phishing, and malware distribution. Previous Twitter spam detection schemes have used account features such as the ratio of tweets containing URLs and the account creation date, or relation features in the Twitter graph. Malicious users, however, can easily fabricate account features. Moreover, extracting relation fea...

A necessary condition for justifying a policy such as subsidized low-income housing, either via tenant-based rental assistance or construction of public or private projects, is that it has a real effect on market outcomes. In this paper, we examine one aspect of the real effect of subsidized housing – does it increase the housing stock? If subsidized housing raises the quantity of occupied hous...

To explain the low-frequency variation in US equity and debt returns in the 20th century, we solve an equilibrium model in which households face housing collateral constraints. An increase in the ratio of housing to human wealth loosens these borrowing constraints, thus allowing for more risk sharing. The rate of return that households require for holding equity decreases as a result. Feeding t...

Over the past decade, housing costs have risen faster than incomes. The need for affordable rental housing has well outpaced the number of available units as well as funding allocations at the federal level. Local regulation and land use policies that increase the cost of subsidized, mixed-income housing construction and preservation have contributed to the affordability problem. To meet the af...

Internet Electron. J. Mol. Des. 2003, 1, 000–000 Abstract Motivation. Ant colony optimization is one of the most recent nature-inspired metaheuristics. The algorithm mimics cooperative foraging behavior of real life ants, has already exhibited superior performance in solving combinatorial optimization problems. In this work, we have explored the searching capabilities of this metaheuristic for ...

PURPOSE Keratoconus is characterized by the thinning of corneal stroma, resulting in reduced vision. The exact etiology of keratoconus (KC) is still unknown. The involvement of oxidative stress (OS) in this disease has been reported. However, the exact mechanism of OS in keratoconus is still unknown. Thus we planned this study to screen mitochondrial complex I genes for sequence changes in kera...

We present the properties of the 12CO(1-0) and (3-2) line emission from the nuclei of 60 IR luminous SLUGS galaxies. This subsample is flux limited at S60μm ≥ 5.24 Jy with FIR luminosities mostly at LFIR > 10 10 L⊙. The emission line strengths of 12CO(1-0) and (3-2) transitions were compared at a common resolution of ∼ 15, and the line ratios r31 vary from 0.22 to 1.72 with a mean value of 0.66...
