The multi-objective covariance matrix adaptation evolution strategy (MO-CMA-ES) combines a mutation operator that adapts its search distribution to the underlying optimization problem with multicriteria selection. Here, a generational and two steady-state selection schemes for the MO-CMA-ES are compared. Further, a recently proposed method for computationally efficient adaptation of the search ...
خواص مهندسی و زیستی پیریمیدینها، شیمیدانها را در توسعه شیمی این ترکیبات به عنوان مواد رنگزا و ترکیبات کمپلکسی آلی - فلزی ترغیب نموده است. کمپلکسهای آزو- فلز در پلی آمید، پروتئینها و سایر مواد مهندسی نقش بسزایی دارند و بسته به فلزات و لیگاندهایشان فامهای متنوع از زرد تا سبز و مشکی را دارند. در این تحقیق برای اولین بار ابتدا تعدادی از ترکیبات آزو با جفتشدن 4، 6 - پیریم...
BACKGROUNDS AND AIMS The renin-angiotensin system plays an important role in homeostasis. Angiotensin II, which is generated by chymase and angiotensin I-converting enzyme (ACE), controls blood pressure as well as angiogenesis and cell proliferation. The aim of this study was to clarify the association of the chymase gene (CMA/B) and ACE polymorphisms with susceptibility to gastric cancer and p...
BACKGROUND In 2010, the diagnosis and treatment of IgE-mediated CMA were systematized in a GRADE guideline. OBJECTIVES & METHODS After 6 years, the state of the knowledge in diagnosis and treatment of CMA has largely evolved. We summarize here the main advances, and exemplify indicating some specific points: studies aimed at better knowledge of the effects of breastfeeding and the production ...
BACKGROUND Children with cow's milk allergy (CMA) need a cow's milk protein (CMP) free diet to prevent allergic reactions. For this, reliable allergy-information on the label of food products is essential to avoid products containing the allergen. On the other hand, both overzealous labeling and misdiagnosis that result in unnecessary elimination diets, can lead to potentially hazardous health ...
OBJECTIVE From 1986 to 1999, the suicide rate in the Edmonton Regional Health Authority (RHA) was greater than that in the Calgary RHA (mean rate ratio 1.4). We conducted a study to determine whether a similar relation holds for parasuicide, and if so, whether the pattern can be explained at the ecologic level by sociodemographic factors. METHODS The Edmonton and Calgary RHAs provided data on...
Conventional blind beamforming algorithms have no direct notion of the physical Direction of Arrival angle of an impinging signal. These blind adaptive algorithms operate by adjusting the complex steering vector in the case of changing signal conditions and directions. This paper presents Angular CMA, a blind beamforming method that calculates steering angle updates (instead of weight vector up...
Chronic maxillary atelectasis (CMA) is characterized by a progressive decrease in maxillary sinus volume. The factors that promote the stage progression of CMA remain poorly understood. Here, we describe the time course of anatomical changes in a 40-year-old woman with stage II CMA that progressed to stage III disease. She did not show stage progression until she started to develop repetitive s...
cow’s milk allergy (cma) is the most frequent food allergy in children and oral immunotherapy (oit) is a promising approach for treatment of patients. the most challenging cases are anaphylactic with coexisting asthma and proposing safe protocols is crucial especially in high risk groups. considering that cma varies among patients, an individualized oit protocol would be beneficial to achieve a...
