In this paper we show that passive self-assembly in the context of the tile self-assembly model is capable of performing fuel efficient, universal computation. The tile self-assembly model is a premiere model of self-assembly in which particles are modeled by four-sided squares with glue types assigned to each tile edge. The assembly process is driven by positive and negative force interactions...

Face recognition is important in human identification. The biological recognition technique acts as a good method and broad applications in security areas. This work presents a method to improve the face recognition accuracy using a combination of Principal Component Analysis (PCA), and Wavelet Transform. Wavelet Transform is used to decompose the input image with different levels and rearrange...

PURPOSE To describe symptomatic pulmonary emboli from brain arteriovenous malformation embolization with liquid acrylates and to analyze the reasons for these complications and describe preventive techniques. METHODS The clinical records of 182 patients embolized with acrylate glue since 1978 for treatment of brain AVMs were searched for evidence of symptomatic pulmonary complications. Origin...

Stress fractures are commonly seen among soldiers and athletes with the usual sites being the tibia, fibula or the metatarsals. Clinical examination may not be very helpful in such cases unless a high degree of suspicion is directed towards the pathology. We present a case of bilateral synchronous subtrochanteric stress fractures in a Sufi mystic dancer who presented with mild leg pain. The pat...

BACKGROUND Gastro-jejunal anastomotic leak and internal hernia can be life-threatening complications of laparoscopic Roux-en-Y gastric bypass (LRYGBP), ranging from 0.1-4.3% and from 0.8-4.5% respectively. The safety and efficacy of a fibrin glue (Tissucol) was assessed when placed around the anastomoses and over the mesenteric openings for prevention of anastomotic leaks and internal hernias a...

The carnivalesque poetics of the “rogue lyrics” (qalandariyyāt) medieval Sufi poetry have excited interest varied audiences since premodern times. This attention is not surprising: these poems' purported celebration proscribed actions, antinomian figures, and even apostasy shocks readers demands interpretation. Many interpreters, followed by a substantial group contemporary scholars, read image...
