A 69-year-old man was referred to our hospital with dysuria and gross hematuria associated with a rapidly growing perineal mass. Serum squamous cell carcinoma (SCC) antigen level was high (2.4 ng/mL). Magnetic resonance imaging examination revealed a tumor posterior and inferior to the pendular urethra with a cystic lesion inside. Tumor resection together with total penectomy was performed. Pat...

Text in images contains useful information which can be used to fully understand images .This paper proposes an unified method to segment a text region from images such as Scene text images , Caption text & Document images using Contourlet transform . Contourlets not only possess the main features of wavelets (namely, multiscale and time-frequency localization), but also offer a high degree of ...

Cahiers de l'Ifas is an occasional working paper published by Ifas, dedicated to disseminating research on social issues in Southern Africa. Under the guidance of appointed editors, each issue covers a specific theme; papers originate from researchers, experts or students, local or not, with an interest in the region. The views and opinions expressed here remain the sole responsibility of the a...

From-region visibility culling is considered significantly harder than from-point visibility culling, since it is inherently 4dimensional. We present a conservative occlusion culling method based on factorizing the 4D visibility problem into horizontal and vertical components. The visibility of the two components is solved asymmetrically: the horizontal component is based on a novel parameteriz...

where α is some constant. Here, mismatches are not directly penalized; a good score is achieved by having a close fit in some region where the auxin concentration ai is high, i.e. near to the peak. This means that the gaussian is able to follow the peak and neglect outlying values. One flaw with this method is that the fitted gaussian can have values greater than the counts over an extended reg...

Significant 1.8 MeV emission from the Carina region has been detected by COMPTEL. The emission is concentrated within 6 degrees or less near the Carina nebula NGC 3372, one of the brightest H II regions known in our Galaxy. This region contains a wealth of extreme young open clusters whose massive stars possibly contributed to an enrichment of Al in the ISM within the last few million years. Th...

In this paper, we explore ways to combine boundary information and region segmentation to estimate regions corresponding to foreground objects. Boundary information is used to generate an object likelihood image which encodes the likelihood that each pixel belongs to a foreground object. This is done by combining evidence gathered from a large number of boundary fragments on training images by ...

Flavonoids play an important role in interactions of plants with the environment. Liquid chromatography (HPLC) was used to determine the flavonoid profiles (especially luteolin, tricin, and chrysoeriol glycosides), their total concentrations, and changes in the amounts of eight flavones found in the aerial parts of alfalfa (Medicago sativa L.) (Fabaceae) Radius cv., uninfested and infested by t...

Cysteines were introduced, one at a time, at amino acid positions 55-75 in the cytoplasmic region connecting helices I and II in rhodopsin. In each of the 21 cysteine mutants, the reactive native cysteine residues (C140 and C316) were replaced by serine. Except for N55C, all mutants formed rhodopsin-like chromophores and had normal photobleaching characteristics. The efficiency of GT activation...

The Food and Drug Administration (FDA) recently has re-released chymopapain, an injectable proteolytic enzyme used as an alternative to lumbar laminectomy in selected patients. The reported success rate, over 800%, has inspired an increasing usage of chymopapain. However, there is a reported 1 % incidence of anaphylaxis upon injection of this drug. The authors describe the means of early recogn...
