Analysis of physical changes in Fars province water zones related to climatic parameters using remote sensing, Bakhtegan, Tashk, Iran

Egyptian Journal of Remote Sensing and Space Sciences, 2023
In recent decades, severe climate change, decreased precipitation, temperature rise, and increased evapotranspiration (ET) have significantly reduced waterbodies. Furthermore, governments have prioritized the study of water level fluctuations of lakes to

Asteroseismology of KIC 11754974: A high-amplitude SX Phe pulsator in a 343-d binary system [PDF]

, 2013
The candidate SX Phe star KIC 11754974 shows a remarkably high number of combination frequencies in the Fourier amplitude spectrum: 123 of the 166 frequencies in our multifrequency fit are linear combinations of independent modes. Predictable patterns in

Low repetition rate 343 nm passively Q-switched solid-state laser for time-resolved fluorescence spectroscopy.

Optics Express, 2018
We demonstrate a low-cost 343 nm solid-state laser delivering up to 20 µJ per pulse, with a pulse width of 2.3 ns at a repetition rate of 100 Hz. The 343 nm is obtained through a third harmonic generation of a passively Q-switched 1030 nm Yb:YAG laser ...

Persistence and decay of human antibody responses to the receptor binding domain of SARS-CoV-2 spike protein in COVID-19 patients

Science immunology, 2020
IgM and IgA responses to SARS-CoV-2 RBD in severe COVID patients decay rapidly, while IgG responses persist for over 3 months. We measured plasma and/or serum antibody responses to the receptor-binding domain (RBD) of the spike (S) protein of SARS-CoV-2 ...
