Several problems in optimization and control involve a matrix of decision variables to be subject to a rank constraint. Although semidefinite programming is used as a generalpurpose tool to provide strong relaxations of such problems, finding feasible solutions mostly relies on algorithmic techniques specific to the problem at hand. We present models for expressing rank constraints using mathem...

We study the set of possible joint posterior belief distributions a group agents who share common prior regarding binary state and observe some information structure. For two agents, ...

Introduction: Radiotherapy is one of the treatment options for locally advanced prostate cancer, however with standard radiation doses it is not always very effective. One of the strategies to improve the efficiency of radiotherapy is increasing the dose. In this study to increase tumor local control rates a new radiotherapy method, known as dose painting (DP) was investigated....

Introduction: The applicability of sentinel lymph node biopsy for early detection of metastasis in patients with renal cell carcinoma (RCC) is still in the validation phase and under investigation, which might be due to the unpredictability of the lymphatic pattern in RCC. In this study, we aimed to evaluate the feasibility and accuracy of sentinel node biopsy in patients with ...

The strong coupling, multivariate, and nonlinear characteristics of the mathematical model a doubly-fed induction generator (DFIG) make it challenging to analyze bifurcation category DFIG. Therefore, in this study, we developed method for analyzing DFIG via topologically equivalent dimensionality reduction neighborhood values based on central manifold theorem realized discrimination Hopf type W...

Introduction: Overexpression of Human Epidermal Growth factor Receptor-2 (HER-2) is one of the most important prognostic and predictive factors of breast cancer, observed in 25% - 30% of breast carcinoma patients leading to poor prognosis and feasible anti HER-2 antibody drugs. The objective of this study was to evaluate the HER-2 frequency in target population and its correlat...

SEMI-MARKOV DECISION INCLUDING AN UNKNOWN Masami Kurano Chiba University PROCESSES PARAMETER (Received February 27, 1984: Revised May 8,1985) We consider the problem of minimizing the long-run average (expected) cost per unit time in a semiMarkov decision process including an unknown parameter. In the case of general state and action spaces and compact parameter space we construct the adaptive ...

— The Economics of Happiness is one of the research areas of greatest growth in recent years. Throughout this work, a venture based model in which satisfaction of Spanish entrepreneurs with their professional life is performed. We analyze the responses of 9,989 entrepreneurs using data from the Global Entrepreneurship Monitor (GEM), and six hypothesis are discussed. The results show that, for t...
