We describe a novel technique for the fast production of large point sets with different spectral properties. In contrast to tile-based methods we use so-called AA Patterns: ornamental point sets obtained from quantization errors. These patterns have a discrete and structured number-theoretic nature, can be produced at very low costs, and possess an… (More)
Writing this thesis work was a draining task. It has given me a new insight into how all of those stacks of theses found at The American University in Cairo library actually got there. Those theses represent not only the work of their authors, but also of all the reviewers and advisors who play a role in that long trail from thesis topic selection to its… (More)
During the last few decades, most of microbiology laboratories have become familiar in analyzing Sanger sequence data for ITS barcoding. However, with the availability of next-generation sequencing platforms in many centers, it has become important for medical mycologists to know how to make sense of the massive sequence data generated by these new… (More)
Multidrug-resistant (MDR) Gram-negative infections represent a growing problem and a serious global threat. Carbapenem-resistant Klebsiella pneumoniae is perhaps cause the most difficult infection to treat and is associated with increased morbidity and mortality. Here, we report the draft genome sequence of an MDR K. pneumoniae strain isolated from Makkah,… (More)
We present a description of a rare but dangerous case of fungal meningitis caused by Aspergillus terreus in an immunocompetent patient with a history of sinus disease.
The emergence and spread of multidrug-resistant (MDR) bacteria have been regarded as major challenges among health care-associated infections worldwide. Here, we report the draft genome sequence of an MDR Stenotrophomonas maltophilia strain isolated in 2014 from King Abdulla Medical City, Makkah, Saudi Arabia.
We present a new approach for stippling by recursively dividing a grayscale image into rectangles with equal amount of ink, then we use the resulting structure to generate novel line-based halftoning techniques. We present four different rendering styles which share the same underlying structure, two of which bear some similarity to Bosch-Kaplan's TSP Art… (More)
We explore the use of Truchet-like tiles (tiles with half area shaded) for single-tone (monochrome) line-based rendering of maps. We borrow concepts from information theory to develop some qualitative and quantitative measures, and use them to discuss four rendering styles which use Truchet-like tiles. We first present a style based on the original Truchet… (More)
