Background: Intrauterine Device (IUD) is an effective and long term method of contraception that can be used without continued effort by the user to prevent pregnancy perfectly. Pain during IUD insertion is one of the obstacles to properly using the device. Thus, using different methods of analgesia and anesthesia to alleviate this pain has been studied by many researchers. This review article ...
This paper deals with the selection of the spreading sequences for the downlink and the uplink Multi-Carrier Code Division Multiple Access systems with the aim of minimizing the Multiple Access Interference and the dynamic range of the transmitted multicarrier signal.
Several millimeter Wave (mmWave) bands, which suffer from rain attenuation, were identified in the World Radiocommunication Conference 2019 (WRC-19) for fifth generation (5G) radio networks. In this paper, long-term attenuation is measured over typical building to links built environment, constitute two 36 m along a direct link and an indirect side at 25.84 77.54 GHz 200 77.125 GHz. The was als...
در این پروژه، ابتدا هشت جهش شایع ژن cyp21a2 در 54 خانواده مبتلا مراجعه کننده به مرکز طبی کودکان، با روش arms-pcr تعیین شده و سپس در نمونه های مشکوک، حذف ها و مضاعف شدگی های بزرگ ژنcyp21a2 با روش های mlpa، long range pcr و هضم آنزیمی به صورت کمی و نیمه کمی بررسی و پس از تعیین همبستگی ژنوتیپ-فنوتیپ، هاپلوتایپ های بیماران استنتاج گردیدند. در ادامه، بقیه نمونه ها توالی یابی شدند. با نرم افزارهای بی...
One of the main open challenges in visual odometry (VO) is the robustness to difficult illumination conditions or high dynamic range (HDR) environments. The main difficulties in these situations come from both the limitations of the sensors and the inability to perform a successful tracking of interest points because of the bold assumptions in VO, such as brightness constancy. We address this p...
We study how the range of variation and the number of attribute levels affect five measures of attribute importance: full profile conjoint estimates, ranges in attribute level attractiveness ratings, regression coefficients, graded paired comparisons, and self-reported ratings. We find that all importance measures are affected by the range manipulation. The number of attribute levels affects on...
Early B cell development is characterized by large-scale Igh locus contraction prior to V(D)J recombination to facilitate a highly diverse Ig repertoire. However, an understanding of the molecular architecture that mediates locus contraction remains unclear. We have combined high-resolution chromosome conformation capture (3C) techniques with 3D DNA FISH to identify three conserved topological ...
We report a method to determine propagation delays of optical 10 Gb/s data traveling through a 75 km long amplified fiber link with an uncertainty of 4 ps. The one-way propagation delay is determined by two-way exchange and cross correlation of short (< 1 ms) bursts of 10 Gb/s data, with a single-shot time resolution better than 2.5 ps. We thus achieve a novel optical communications link suited...
