In this article we generalize the CM method for elliptic and hyperelliptic curves to Picard curves. We describe the algorithm in detail and discuss the results of our implementation.
Competitiveness and survivability of many companies today does not only depend on their products and development processes. It also strongly depends on how effective the organizations are in managing emergency software problems. Despite this, there is only one process model dealing with software emergencies. It is CM 3 : Emergency Problem Management. In this paper, we evaluate CM 3 : Emergency ...
تهیه و بررسی کاربرد کاتالیزگر o-کربوکسی¬متیل¬کیتوسان-n-بوت-4-ایل¬سولفونات (cm-cbsa) در این پایان¬نامه ارائه شده است. به نظر می¬رسد cm-cbsa به عنوان یک دهنده-پذیرنده پروتون و یا اینکه به عنوان آمین نوع دوم و با تولید ایمین و انامین¬های فعال میانی واکنش¬ ترکیبات کربونیلی را کاتالیز کند. cm-cbsa همچنین می¬تواند به عنوان یک بستر عمل می¬کند به¬طوری که با برجذب واکنش¬دهنده¬ها بر سطح خود موجب تسریع وا...
OBJECTIVE To compare incidence of hospital-onset Clostridium difficile infection (CDI) measured by the use of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) discharge diagnosis codes with rates measured by the use of electronically available C. difficile toxin assay results. METHODS Cases of hospital-onset CDI were identified at 5 US hospitals durin...
International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes have been proposed as a method of public health surveillance and are widely used in public health and clinical research. However, ICD-9-CM codes have been found to have variable accuracy for both health-care billing and disease classification, and they have never been comprehensively validated for u...
BACKGROUND AND PURPOSE This study evaluated the effect of migraine on the subsequent development of epilepsy. METHODS A total of 10,016 patients diagnosed with migraine [ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification) 346] during the period between 2000 and 2009 who were aged older than 20 years were identified as the migraine cohort. A comparison co...
There are substantial barriers to the introduction of hydrogen fuel cells for transportation, including the high cost of fuel-cell systems, the current lack of a hydrogen infrastructure, and the relatively low fuel efficiency when using hydrogen produced from hydrocarbons. Here, we describe a solid oxide fuel cell that combines a catalyst layer with a conventional anode, allowing internal refor...
