BACKGROUND Halitosis is a common problem that affects a large portion of the population worldwide. The origin of this condition is oral in 90% and systemic in 10% of cases. The unpleasant odor is mainly the result of volatile sulfur compounds produced by Gram-negative bacteria. However, it has recently been found that anaerobic Gram-positive bacteria also produce hydrogen sulfide (H2S) in the p...

hydrargyri perchloridum solution and later with sterile distilled water. Saline is not to be used on account of its decomposing effects on the solutions used for tattooing. The next step is to scrape off the superficial corneal epithelium. Ordinary Graefe's knives, secondary knives, scalpels, discission needles, pterygium knives and many other instruments have been used to scrape the cornea, bu...

Modern software ecosystem is data-centric. Data exfiltration due to the attacks of Memory Scraper type malwares is an emerging threat. In this paper, we set up an appropriate mathematical model capturing the threat such attacks pose to Identity Based Cryptosystems (IBE). Following the formalism, we demonstrate an attack on popular Boneh-Franklin CCA2 secure IBE construction that compels us to r...

The male genitalia of many animal groups have elaborate and species-specific forms. One hypothesis to explain why this is so is that male genitalia function as stimulatory devices that are under sexual selection by cryptic female choice. This report is based on a videotaped observation of a single male of an unidentified species of Tipula (Bellarina) from San José Province, Costa Rica. A male c...

In order to fully examine the breadth of possibility in sports data analysis, we look at two areas of differing scope. The first is scalable and generalizable, exploring the expected performance of athletes in track and field events by means of a datacentric model. It takes Athletic.net data using an in-house web scraper and fits past results against a corpus in order to predict future results ...

Using channeling in a 5-mm crystal with bending angle of 0.65 mrad, a record high efficiency, over 60%, of particle extraction from accelerator was achieved. The extracted beam intensity was up to 5.2×10 11 protons per spill of ∼0.5 s duration. Also, the first proof-of-principle experiment on 'crystal collimation' was performed where crystal-serving as a scraper-has reduced the radiation level ...
