Abstract

Recent breakthroughs in Transmission Network Expansion Planning (TNEP) have demonstrated that the use of robust optimization, as opposed to stochastic programming methods, renders the expansion planning problem considering uncertainties computationally tractable for real systems. However, there is still a yet unresolved and challenging problem as regards the resolution of the dynamic TNEP problem (DTNEP), which considers the year-by-year representation of uncertainties and investment decisions in an integrated way. This problem has been considered to be a highly complex and computationally intractable problem, and most research related to this topic focuses on very small case studies or used heuristic methods and has lead most studies about TNEP in the technical literature to take a wide spectrum of simplifying assumptions. In this paper an adaptive robust transmission network expansion planning formulation is proposed for keeping the full dynamic complexity of the problem. The method overcomes the problem size limitations and computational intractability associated with dynamic TNEP for realistic cases. Numerical results from an illustrative example and the IEEE 118-bus system are presented and discussed, demonstrating the benefits of this dynamic TNEP approach with respect to classical methods., Comment: 10 pages, 2 figures. This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication.

Abstract

This paper shows the complementary roles of mathematical and engineering points of view when dealing with truss analysis problems involving systems of linear equations and inequalities. After the compatibility condition and the mathematical structure of the general solution of a system of linear equations is discussed, the truss analysis problem is used to illustrate its mathematical and engineering multiple aspects, including an analysis of the compatibility conditions and a physical interpretation of the general solution, and the generators of the resulting affine space. Next, the compatibility and the mathematical structure of the general solution of linear systems of inequalities are analyzed and the truss analysis problem revisited adding some inequality constraints, and discussing how they affect the resulting general solution and many other aspects of it. Finally, some conclusions are drawn., Comment: 39 pages and 17 figures

Abstract

Objetivo: Determinar el efecto de la dosis de radiación en los resultados de control bioquímico y morbilidad en pacientes con cáncer de próstata. Material y Métodos: Entre 1995 y 2003, 360 pacientes con cáncer de próstata T1-T3b fueron tratados con RTC3D (66,0 Gy-82,6 Gy). Los pacientes fueron asignados a uno de tres grupos pronósticos: a) bajo riesgo: tratados con RTC3D exclusiva; b) riesgo intermedio tratados con deprivación androgénica (DA) neoadyuvante 4-6 meses previos y durante RTC3D; y c) alto riesgo: DA previa, durante y dos años tras RTC3D. Para el análisis de toxicidad tardía se empleó la escala de RTOG/EORTC. Resultados: Con una mediana de seguimiento de 48 meses (12-138), la supervivencia libre de fracaso bioquímico (SLFB) a 4 años en pacientes de bajo riesgo fue del 88%, en los de riesgo intermedio fue del 68% y en los de alto riesgo del 79%. En el análisis estratificado del efecto de la dosis de RTC3D controlado por el uso de hormonoterapia, y en el análisis multivariante, tanto la dosis alta de irradiación (>76 Gy) (p=0,0053), como el empleo de DA durante dos años en alto riesgo (p=0,0046) se correlacionan de forma independiente con un mejor control bioquímico. La incidencia de sangrado rectal y urinario grado 2 fue del 7% y 11% respectivamente. Conclusión: Estos datos confirman que tanto la RTC3D a dosis altas como la asociación de DA en pacientes de alto riesgo contribuyen de forma independiente a mejorar de forma significativa los resultados del tratamiento de los pacientes con cáncer de próstata. Purpose: The present study was undertaken to determine the effect of radiation dose on biochemical control and morbidity in prostate cancer patients. Materials and Methods: Between 1995 and 2003, 360 patients with T1-T3b prostate cancer were treated in a sequential radiation dose escalation trial from 66.0 to 82.6 Gy. These patients were prospectively assigned to 1 of 3 prognostic groups according to risk factors: a) low risk patients were treated with 3DCRT alone; b) intermediate risk patients were allocated to receive neoadjuvant AD (NAD) 4-6 months prior and during 3DCRT; and c) highrisk received NAD and adjuvant AD (AAD) 2 years after 3DCRT. RTOG/EORTC toxicity score was used to analyze late complications Results: Median follow-up was 48 months (12-138). The actuarial biochemical disease free survival (bDFS) at 4 years for low risk, intermediate risk and high risk patients was 88%, 68% and 79% respectively. Stratified and multivariate analysis showed that higher radiation dose (>76 Gy) (p=0.0053) and the use of AAD for high risk patients (p=0.0046) correlated significantly with an improvement of bDFS for all patients. The incidence of late grade 2 rectal and urinary bleeding were 7% and 11% respectively. Conclusion: The present study confirms an independent benefit of high-dose (> 76 Gy) radiation therapy and long-term AAD in high-risk prostate cancer patients.
