RNA 2-Way junctions RMSD cutoff?5 answersThe RMSD cutoff for RNA 2-way junctions is crucial for assessing structural similarity. Research by Amélie Héliou et al. presents a kinematics-based method for morphing RNA molecules between conformations, achieving low all-atom RMSD by directing fewer than 1% of atoms. Additionally, studies by Anthony M. Mustoe et al. highlight how topological constraints at the RNA secondary structure level significantly restrict orientations sampled by helices across 2-way junctions, providing insights into the behavior of RNA junctions. Understanding these constraints and utilizing advanced computational methods can help establish an appropriate RMSD cutoff for accurately comparing RNA 2-way junction structures.

What is the the type of propagation method for rose?5 answersRose propagation methods include in vitro regeneration system using nodal explants, cutting propagation method with obliquely cut branches inserted into planting media, cutting propagation method with 5-7cm long cuttings immersed in indoleacetic acid solution and inserted into perlite substrate, cutting propagation method with branches collected in February and March and inserted into nutrient solution in cutting containers, and summer cutting propagation method with branches inserted into seedbeds and covered with sunshade nets.
How does the aurora affect radio propagation?5 answersThe aurora can have profound effects on radio propagation. Disturbances in the auroral and polar-cap ionosphere can affect radio signals from ELF through VHF on terrestrial and earth-space paths, especially during sunspot maximum and disturbed periods. Turbulences of plasma caused by precipitated electrons can intensify HF radio emissions, with the predominant emissions having a frequency double that of the plasma. Transequatorial propagation on ionospheric scintillations is most likely to occur during solar maximum, particularly affecting equatorial and auroral regions. The effects of ionospheric weather on RF and GNSS systems include consequences for radio communications, space-based navigation and positioning, and surveillance. The association between the optical aurora and the effects of enhanced ionization on radio wave propagation include local absorption of radio waves, reflection from an extraordinary E-layer, scattering of radio waves, VLF radio emissions, radio noise, and polar cap absorption events.
What are the effects of laser on adjacent tissues?3 answersLaser therapy can have various effects on adjacent tissues. The use of highly sensitive laser devices with optimal wavelengths allows for deep penetration into biological tissues, leading to the appearance of uncontrolled human infrasonic vibrations associated with the vascular system and respiratory movements. Different laser types and properties can result in thermal degradation of tissues, but ultrafast lasers have shown promise in minimizing thermal impact and enabling precise excisions with nonthermal ablation mechanisms. Laser-induced radiation has been found to have anti-inflammatory effects, accelerate tissue regeneration, and improve blood supply to organs. However, laser therapy also carries risks and potential side effects, such as bleeding, pain, and infection. Therefore, it is important to consider the advantages and disadvantages of laser treatment and choose the best approach to minimize side effects.
