PurposeCardiac toxicity after breast cancer (BC) radiation therapy is partly due to the large doses coronary arteries. The left anterior descending artery (LAD) particularly exposed. A first step in achieving robust dose constraints LAD during treatment planning homogeneous delineation based on guidelines. can be problematic heart movements. aim of study was establish a safety margin for patien...

We provide a formula for the cardinality constraint, a lower bound in the form of |F | ≥ K, in such a way that the conjunction of the BFC and the OFC (explained below) can be solved simultaneously. The parameter K can vary from instance to instance. We assume the availability of a successor predicate, and that the domain is ordered. To our knowledge, no polynomially solvable expression has been...

A parallel matheuristic algorithm is presented as a spin-off from the exact Branch-and-Fix Coordination (BFC) algorithm for solving multistage stochastic mixed 0-1 problems. Some steps to guarantee the solution’s optimality are relaxed in the BFC algorithm, such that an incomplete backward branching scheme is considered for solving large sized problems. Additionally, a new branching criterion i...

BACKGROUND The rate of exclusive breastfeeding in Iran is decreasing. The breastfeeding attrition prediction tools (BAPT) have been validated and used in predicting premature weaning. OBJECTIVES We aimed to translate the BAPT into Farsi, assess its content validity, and examine its reliability and validity to identify exclusive breastfeeding discontinuation in Iran. MATERIALS AND METHODS Th...

An important phase in the step cycle is foot contact. When the moment of foot contact differs from the one expected, a fast response is needed. Such a mismatch can be caused by hitting a support surface earlier or later than expected. To study this, experiments were performed with healthy young adults who walked on a platform that was unexpectedly at a lowered (5 cm) or at a level height. Glass...

Background The widespread acceptance and application of 68Ga-PET depends on our ability to develop radiopharmaceuticals that can be prepared in a convenient and suitable manner. A kit-type labelling protocol provides such characteristics and requires chelators that can be radiolabelled under exceptionally mild conditions. Recently the DATA chelators have been introduced that fulfil these requir...

objectives we aimed to translate the bapt into farsi, assess its content validity, and examine its reliability and validity to identify exclusive breastfeeding discontinuation in iran. materials and methods the bapt was translated into farsi and the content validity of the farsi version of the bapt was assessed. it was administered to 356 pregnant women in the third trimester of pregnancy, who ...
