This investigation uses a multidisciplinary approach including geomorphic surface mapping, soil stratigraphic analysis, radiocarbon dating and optically stimulated luminescence (OSL) dating to investigate the chronology of soil formation and aeolian activation periods recorded in ridge dune deposits as well as the spatial variability of aeolian processes during active aeolian episodes. This stu...

We define two proper subclasses of subsequential functions based on the concept of Strict Locality (McNaughton and Papert, 1971; Rogers and Pullum, 2011; Rogers et al., 2013) for formal languages. They are called Input and Output Strictly Local (ISL and OSL). We provide an automata-theoretic characterization of the ISL class and theorems establishing how the classes are related to each other an...

We used Optically Stimulated Luminescence (OSL) from X-ray-irradiated sodium chloride nanocrystals to investigate how silver nanoparticle (AgNP) films enhanced luminescence. We controlled the emitter-AgNP distance and used the OSL intensity and decay times to explore the plasmonic interactions underlying the enhanced luminescence. Both intensity and decay times depended on the emitter-AgNP dist...

Grid computing utilizes distributed heterogeneous resources to support large-scale or complicated computing tasks, and an appropriate resource scheduling algorithm is fundamentally important for the success of Grid applications. Due to the complex and dynamic properties of Grid environments, traditional model-basedmethodsmay result in poor scheduling performance in practice. Scalability and ada...

Abstract The results reported herein were motivated by the potential application of combined optically stimulated (OSL) and thermoluminescence (TL) measurements for separation between beta neutron dose components in mixed neutron-beta radiation fields. advantages OSL/TL are two-fold: (i) OSL TL readout can be carried out on same sample (ii) greater efficiency to high ionization density (HID) du...

Higher eukaryotes’ phenotypes–the unique properties of a system composed of several genes and their relations–are entirely different from a set of properties of individual genes. During evolution, higher organisms’ genes become multipurpose and their phenotypic implication become abstract. We hypothesize that an operating system of life (OSL) exists in “genome space,” encoding a variety of phen...

This paper presents the results of TL and OSL dating of soil and fragments of bricks from a grave, which was occupied by two mummified nuns, found at "Luz" Monastery, located in the state of São Paulo, Brazil. The TL and OSL ages were compared to C-14 dating ones obtained from bone collagens of the mummies. The majority of the ages is related to the eighteenth century. The gamma-ray spectroscop...

thermoluminescence (tl) dating was established in oxford to fulfil the demand for dating ceramics and other heated man made products (aitken, 1985).  it determines the time elapsed since the mineral grains have been heated. following the establishment of tl dating method, it was used to date fired materials such as pottery, flint and etc. optically stimulated luminescence (osl) determines the t...

در بررسی­های فونستیک سال 2011 دامنه جنوبی رشته کوه­های زاگرس ایران، یک نمونه ماده از گونه Amphipyra kautti Hacker, 2002 متعلق به خانواده Noctuidae و زیرخانواده Amphipyrinae مناطق کوهستانی استان کهگیلویه بویراحمد جمع­ آوری شناسایی شد. این که برای اولین بار ایران گزارش می­شود، همراه با ویژگی­های افتراقی، تصویر الگوی بال اندام تناسلی شده ارائه است. اطلاعات مربوط دیگر همین جنس مطالعه نیز
