Picture 1. Comparison of chest x-ray and three-dimensional images. A) Posteroanterior chest xray film on admission showed a large mass occupying the right lower-lung field (arrow) with a right-sided aortic arch (arrowhead). B) Three-dimensional image by MDCT clearly showed aneurysms of the right-sided descending thoracic aorta (arrow) with a right-sided aortic arch (arrowhead) and abdominal aor...

Millions of women are screened for breast cancer every year, resulting in tens of millions of xray images that need to be read. The reading rooms that are used vary greatly, and many radiologists express concern about the conditions in either their workplace or the workplaces of their colleagues. Now that softcopy mammography screening is becoming commonplace, there is an opportunity to revisit...

Previous work has demonstrated the accumulation of negative charges on anode side ion conductor Rb2Ti2O5 when placed under voltage between two metallic electrodes. The nature these accumulated species and conducting ions is investigated by a combination thermogravimetric analysis (TGA), Xray diffraction, dielectric response measurements, charge distribution, IR absorption spectroscopy nuclear m...

In this study, thin films of pure iron oxide (Fe3O4) were prepared using pulsedlaser deposition technique under vacuum (2×10-3 mbar) Nd: YAG laser atdifferent energies (700, 800, 900, and 1000 mJ) on quartz slides at thesubstrate temperature 200 °C with different thickness (170,190, 220, 250nm). The examined techniques. Xray diffraction showed a polycrystalline structure cubic Fe3O4 phase, enha...

ضرورت دسترسی به کاربردهای وسیع تصاویر ابرطیفی سبب توسعة سیستم‌های تصویربرداری نوآورانه و اقتصادی در ثبت این شده است. به‌منظور استفاده از تصاویر، لازم است ارتباط هندسی دقیقی میان آنها فضای زمین برقرار شود فرایند نیازمند نقاط کنترلی بسیاری نکته راهکارهای اصلاح منطبق با ساختار هریک دوربین‌ها را بارز می‌کند. سنجندة (nm 400-1000) BaySpec OCI-F یکی نوآورانه‌ای که هندسة پوش‌بروم دریافت سنجنده، علاوه‌ب...

The success of deep learning has set new benchmarks for many medical image analysis tasks. However, models often fail to generalize in the presence distribution shifts between training (source) data and test (target) data. One method commonly employed counter is domain adaptation: using samples from target learn account shifted distributions. In this work we propose an unsupervised adaptation a...

شب پره جوانه خوار بلوط Tortrix viridana, Linnaeus, 1758 (Lep. Tortricidae) یکی از آفات مهم گونه های مختلف جنس Quercus spp. می باشد. لاروهای این آفت ها و برگ درختان تغذیه نمایند باعث بی برگی کامل مورد نظر شوند. در تحقیق تفاوت ژنتیکی پروانه با استفاده مارکرهای ISSR بر اساس میزبان آن جنگل شمال غرب ایران مطالعه قرار گرفت. 19 جمعیت شامل 171 فرد که سه branti Lindl. 1840, infectoria Oliv. 1801 libani ...
