Introduction: The aim of the present study was to assess the radiosensitivity parameters for SK-BR-3 (SKBR3) breast cancer cells that could be implemented in the cutting-edge treatment planning systems (TPS) for accelerated partial-breast irradiation (APBI). Materials and Methods: The cell survival fraction and its relevant radiosensitivity coefficients, namely α and β, in linear-quadratic (LQ)...

The digital control is an important aspect of today’s technologies and industrial environment. This thesis presents the digital control of an unstable Ball & Plate system from the mathematical model to real-model control. There are many different controller design approaches and the one used here is based on the minimization of linear quadratic LQ criterion for 2DOF controller structure using s...

By relating a novel predictive controller to LQ designs stability theorems are deduced, and extensions to Generalized Predictive Control give model following, state-dead-beat and pole-placement control objectives. Abstract-The original GMV self-tuner was later extended to provide a general framework which included feedforward compensation and user-chosen polynomials with detuned model reference...

For tumor therapy with light ions and for experimental aspects in particle radiobiology the relative biological effectiveness (RBE) is an important quantity to describe the increased effectiveness of particle radiation. By establishing and analysing a database of ion and photon cell survival data, some remarkable properties of RBE-related quantities were observed. The database consists of 855 i...

introduction: with regard to the importance of life quality (lq) in patients with cancer, especially breast cancer, and research conflicts about quality and quantity of the effect of counseling on lq promotion in such patients and for determining the effect of group counseling on symptom scales of lq in patients with breast cancer treated by chemotherapy, this study was carried out at the at th...

The observation of a possible excess of both neutral and charged current events at HERA has brought the discussion of leptoquarks(LQs) and their properties off the back burner, though they have been subjects of study for quite some time. For more than a decade any discussion of leptoquark models has been historically based on the classic work by Buchmüller, Rückl and Wyler (BRW). As these autho...

Cell survival is conventionally defined as the capability of irradiated cells to produce colonies. It is quantified by the clonogenic assays that consist in determining the number of colonies resulting from a known number of irradiated cells. Several mathematical models were proposed to describe the survival curves, notably from the target theory. The Linear-Quadratic (LQ) model, which is to da...

This paper considers point and interval estimation of the lq loss of an estimator in high-dimensional linear regression with random design. We establish the minimax rate for estimating the lq loss and the minimax expected length of confidence intervals for the lq loss of rate-optimal estimators of the regression vector, including commonly used estimators such as Lasso, scaled Lasso, square-root...

A 124 (1882–2005) summer record of total surface energy content consisting of time series of surface equivalent temperature (TE) and its components T (mean air temperature) and Lq/cp (moist enthalpy, denoted Lq) is developed, quality controlled, and analyzed for Columbus, Ohio, where long records of monthly dewpoint temperature are available. The analysis shows that the highest TE occurs during...

This technical report considers the design of optimal trajectories of linearly constrained linear quadratic (LQ) systems. It is shown that by applying a Fourier-based state parameterization approach a linearly constrained LQ problem can be converted into a quadratic programming problem. Simulation results show that the proposed approach is an accurate and computationally efficient design tool f...
