| We consider local EM to analyze point process data that are either interval-censored or aggregated into counts. The use of local likelihood methods (Tibshirani and Hastie, 1987; Loader, 1996) in the presence of interval-censored or aggregated data leads to a natural consideration of an EM-type strategy, or a local EM algorithm. We present the formulation of local EM algorithms to estimate density, intensity and risk and their implementations using piecewise constant functions. From a theoretical perspective, local EM and the EMS algorithm complement each other. We demonstrate that an EMS algorithm rises naturally from a local likelihood consideration in the context of point processes while the EMS algorithm serves as a rapid implementation of local EM algorithms and provides theoretical tools to better understand the role of local EM. It is shown that the use of the piecewise constant function at the E-step explicitly results in an iteration that involves an expectation, maximization and smoothing step, or an EMS algorithm considered in Silverman et al. (1990). Consequently, we reveal a previously unknown connection between local EM and the EMS algorithm. |
Оптимізація хірургічного лікування діабетичної... Установлено, что у наблюдавшихся больных отмечаются значительные нарушения в системе АОЗ на фоне активации ПОЛ в крови и тканях гнойной раны. Это приводит к интоксикации организма, нарушению фазности репаративных процессов в ране. Нами был разработан способ местной фотохимической антиоксидантной терапии, применение которой позволило уменьшить активность ПОЛ и стабилизировать функцию системы АОЗ. На фоне такого лечения в короткие сроки уменьшается интоксикация организма, активируются репаративные процессы в ране. Обнаружено, что сочетание фотохимической терапии и системной энзимотерапии у таких больных обеспечивает фазность течения репаративных процессов и уменьшает сроки лечения на 7,05 суток, а количество осложнений снижает с 16,9 % до 11,2 %. Ключевые слова: сахарный диабет, местное фотохимическое воздействие, перекисное окисление липидов, антиоксидантная защита, апоптоз, серратиопептидаза. SUMMARY Dolgopolov V.V.

Design and Analysis of New Sequential and Parallel Algorithms Книга по Требованию Built upon a variety of known algorithmic methods, a number of efficient new sequential algorithms for an extended version of the original problem (K>1) are designed and analysied mathematically and empirically. The empirical evaluation of each new sequential algorithm is mostly consistent with the theoretical worst case time complexity. Previous parallel algorithms for the 2D problem have huge demand for hardware resources, or their target parallel computation models are in the realm of pure theoretics. Two new parallal algorithms based on the mesh topology offer a good compromise between speed and cost and greater potential for practical applications. The maximum subarray problem, a classic problem in computer science, involves identifying and locating a contiguous random-sized segment that contains the largest possible sum. This is an abstraction of a number of application domains, such as locating brightest areas in images, a sequencing problem in genomics and a data mining problem. | 3234 |  | Entwicklung einer Webanwendung zur Verwaltung von Pruefungsergebnissen an Hochschulen.
