The problem of determining the location and orientation of straight lines in images is of great importance in the fields of computer vision and image processing. Traditionally the Hough transform, (a special case of the Radon transform) has been widely used to solve this problem for binary images. In this paper, we pose the problem of detecting straight(More)
Endophytes are beneficial microbes that reside intercellularly inside the plants. Interaction of endophytes with the host plants and their function within their host are important to address ecological relevance of endophyte. Four endophytic bacteria OS-9, OS-10, OS-11, and OS-12 were isolated from healthy leaves of Ocimum sanctum. These isolated microbes(More)
Proprietary standardization seeks to increase a firm's market share (pie sharing). Open standardization seeks to increase the size of the market (pie expansion). In order to determine which of these creates more value for a firm involved in standardization , this paper investigates the market value of standardization initiatives, using an event study based(More)
OBJECTIVE To investigate the effectiveness of a modification of the retrosigmoid (RS) approach in reducing the rate of postoperative cerebrospinal fluid (CSF) leak after vestibular schwannoma surgery. PATIENTS Of 1,499 vestibular schwannomas operated on at the Gruppo Otologico between April 1987 and July 2006, 84 cases have been selected, all of them(More)
In today's dynamic business environment many firms must pursue a series of competitive strategies to survive. According to RBV, these strategies are based upon a firm's possession of resources and capabilities that are valuable, imperfectly inimitable, non-substitutable, rare and non-transferable. In this paper we extend research on online communities and(More)
We have recently shown an increase in cholecystectomies for biliary dyskinesia. Based on these results, we hypothesized that diagnostic criteria are less stringently applied which may contribute to ongoing resource utilization. Using billing codes, patients seen for biliary dyskinesia were identified and data were extracted from the electronic medical(More)
In pediatric out-of-hospital cardiac arrest (POHCA), cardiovascular monitoring tools have improved resuscitative endeavors and cardiovascular outcomes but with still poor neurologic outcomes. Regarding cardiac arrest in patients with congenital heart disease during surgery, the application of cerebral oximetry with blood volume index (BVI) during the(More)
We propose two models for dynamic cardiac imaging, based on the spatial and temporal-spectral support of the object. The models explicitly account for the aperiodicity of cardiac motion. The models are used for both adaptive minimum redundancy data acquisition optimized €or the object being imaged and to reconstnct a high temporal resolution movie of the(More)
