Introduction Radiotherapy with small fields is used widely in newly developed techniques. Additionally, dose calculation accuracy of treatment planning systems in small fields plays a crucial role in treatment outcome. In the present study, dose calculation accuracy of two commercial treatment planning systems was evaluated against Monte Carlo method. Materials and Methods Siemens Once or linea...
For a shopping mall, sales leakage occurs when consumer purchases facilitated by the mall are finalized outside it. These sales include, for example, catalog orders filled at the leased premises in a physical mall; For an Internet mall, they include the ones consumers make on an on-line store’s website after learning about the store from an Internet mall website. While these sales are difficult...
We prove that the maximal inscribed beamlet is at least 1/7 of an arbitrary line segment (i.e., beam). The implication of this result is addressed.
با توجه به کاربرد وسیع تلفن همراه و گسترش استفاده از پیامک در میان قشر جوان، هدف این مطالعه بررسی تأثیر کارایی پیامک به عنوان ابزار کمک آموزشی در تدریس و یادگیری ترکیبات هم آئی میان زبان آموزان ایرانی با سطح متوسط زبانی می باشد. بدین منظور، 4 کلاس با 121 زبان آموز انتخاب شده و بصورت تصادفی به گروه های آزمایشی و مقایسه تقسیم شدند. بر اساس نتایج آزمون pet، 90 زبان آموز (زن و مرد) به عنوان شرکت کن...
The aim of the present study was to determine whether MALL expression is associated with colon cancer progression and patient survival. MALL mRNA expression was reduced in the tumor tissues of 70% of the colon cancer patients and 75% of the rectal cancer patients as compared to their normal tissues. MALL protein was also significantly reduced in the tumor tissues of colon cancer patients (P < 0...
This study surveys work that has been done in the field of Mobile Assisted Language Learning. The researchers surveyed 70 corresponding authors of past MALL studies with formatted and open-ended questions, treating them as expert “participant-observers” of their own studies. The findings present details from the respondents about the MALL environments of the studies, the extent to which the MAL...
The minimax correlation between a line segment and a beamlet is proved to be 2 : The result is useful for design of efficient line-segment detectors with noisy data. r 2005 Elsevier B.V. All rights reserved.
The beam is best represented by its distribution in the transverse phase space. In order to determine the transverse velocity distribution, either a pinhole or a thin slit may be used. The slit, however, is more often preferred in many experiments I4 for two,-dimensional phase-space measurement. A beam produced by a hot thermionic cathode or a beam which has existed in a space for a long period...
