Spatiotemporal behavior of a large-scale landslide at Mt. Onnebetsu-dake, Japan, detected by three L-band SAR satellites

Earth, Planets and Space, 2020
We applied differential InSAR analysis to the Shiretoko Peninsula, northeastern Hokkaido, Japan. All the interferograms of long temporal baseline (~ 3 years) processed from SAR data of three L-band satellites (JERS-1, ALOS, ALOS-2) commonly indicate ...

Preserving Proton Resolution Under Cryogenic Dynamic Nuclear Polarization for Biomolecular Solid‐State NMR

Angewandte Chemie, EarlyView.
High‐resolution proton detection is preserved under cryogenic dynamic nuclear polarization (DNP) by combining fast MAS, extensive deuteration and selective methyl protonation. This strategy enables proton‐detected structural studies of biomolecular solids with enhanced sensitivity under DNP conditions.

Monitoring Forest Loss in ALOS/PALSAR Time-Series with Superpixels

Remote Sensing, 2019
We present a flexible methodology to identify forest loss in synthetic aperture radar (SAR) L-band ALOS/PALSAR images. Instead of single pixel analysis, we generate spatial segments (i.e., superpixels) based on local image statistics to track homogeneous

تعیین میزان دقت منابع ارتفاعی مختلف جهت برآورد پهنه سیلاب در رودخانه‌های با شرایط ریخت‌شناسی متفاوت [PDF]

هیدرولیک, 2020
مدیریت رودخانه و کاهش خطرات سیل نیازمند تهیه نقشه‌های حد بستر و پهنه‌بندی سیل است. در این راستا، زمان و هزینه زیاد برداشت زمینی توپوگرافی رودخانه عامل محدود‌کننده بوده است. هدف اصلی از تحقیق حاضر ارزیابی دقت مدل‌های رقومی و ارتفاعی در معرفی هندسه رودخانه‌
