Mục tiêu của nghiên cứu này là quan trắc diễn biến đường bờ sông và biển Cù Lao Dung bằng công nghệ phân tích ảnh viễn thám giai đoạn 2008-2022. Ảnh đa phổ Landsat được sử dụng để loại chiết xuất bờ. Các kết quả cho thấy từ năm 2008 đến 2022, tổng diện tăng 309 ha, giảm 78 tại vị trí xói lở nghiêm trọng nhất có lùi sâu 61 m vào đất liền tốc độ bồi tụ lớn nhất, đã mở rộng thêm khoảng 650 m.

We have proposed and experimentally demonstrated a new technique for creating spin squeezed states of distant atoms by their common interaction with a driven resonator mode. Using this technique we achieve the largest spin squeezing to date, 5.6dB of improvement in signal-to-noise ratio over the standard quantum limit. We have demonstrated a squeezed atomic clock that reaches a given precision ...

By subtracting surface topographies from 1979, 1994, 2000 and 2008, we measured ice thinning rates increasing from 1 m a-1 (1979-1994) to more than 4 m a-1 (2000-2008) on the tongue of the Mer de Glace. The relative contributions of changes in surface mass balance and ice fluxes to this acceleration in the thinning are estimated using field and remote sensing measurements. Between 1979-1994 and...

BACKGROUND Nontuberculous mycobacteria (NTM) have been reported to be increasing worldwide and its geographic distribution differs by region. The aim of this study was to describe the epidemiology and distribution of NTM in the eastern part of China. METHODS Sputum samples were collected from 30 surveillance sites for tuberculosis drug resistance test from May 1, 2008 to December 31, 2008. Id...
