In this paper we study new algorithmic structures with DouglasRachford (DR) operators to solve convex feasibility problems. We propose to embed the basic two-set-DR algorithmic operator into the String-Averaging Projections (SAP) and into the Block-Iterative Projection (BIP) algorithmic structures, thereby creating new DR algorithmic schemes that include the recently proposed cyclic DouglasRach...
AIMS/INTRODUCTION To evaluate whether the adiponectin gene is associated with diabetic retinopathy (DR) risk and interaction with environmental factors modifies the DR risk, and to investigate the relationship between serum adiponectin levels and DR. MATERIALS AND METHODS Four adiponectin polymorphisms were evaluated in 372 DR cases and 145 controls. Differences in environmental factors betwe...
Dietary restriction (DR) increases mammalian lifespan and decreases susceptibility to many age-related diseases. Lifespan extension due to DR is conserved across a wide range of species. Recent research has focused upon genetically tractable model organisms such as C. elegans to uncover the genetic mechanisms that regulate the response to DR, in the hope that this information will provide insig...
اندازه گیری ویژگی های مرتبط با جریان آب در خاک در مقیاس مزرعه، زمان بر، پرهزینه و دشوار است، لذا پژوهشگران برای یافتن پاسخ های سریع و اقتصادی به بسیاری از سوالات، مطالعات را در مقیاسی کوچکتر از مقیاس مزرعه و در آزمایشگاه انجام می دهند. از سوی دیگر، در بسیاری از مطالعات آزمایشگاهی مرتبط با مباحث آب و خاک، پژوهشگران از ستون های خاک با طول ها و قطرهای مختلف استفاده می کنند، بنابراین انتخاب اندازه ...
We recently showed that the dephasing representation (DR) provides an efficient tool for computing ultrafast electronic spectra and that further acceleration is possible with cellularization [M. Šulc and J. Vaníček, Mol. Phys. 110, 945 (2012)]. Here, we focus on increasing the accuracy of this approximation by first implementing an exact Gaussian basis method, which benefits from the accuracy o...
It is impossible to speak too highly of the various admirable and very practical contributions Ferguson made to the Society. They were, one and all, the result of patient research and, latterly, bore the fruits of his wide experience. His mind was a keen and critical one, and his literary style was most lucid and attractive. And now you will allow me to sound the personal note on this greatly b...
