Modified model of Newtonian gravitation.
Тонкие химические технологии, 2011 Within the limits of the classical mechanics for planets of the Solar system a new form of gravitational potential is suggested. The following effects are considered: perihelion advance of the planets, deviation of light beams in the field of the Sun ...

Plants, 2020 Evolutionary change is considered a major factor influencing the invasion of new habitats by plants. Yet, evidence on how such modifications promote range expansion remains rather limited. Here we investigated flower color modifications in the red poppy,

Influence of metal (Ag, Cd, Cu)-doping on the optical properties of ZnO nanopowder: Variation of band gap [PDF]
شیمی کاربردی روز, 2013 Metal doped ZnO (MZO, metal = Ag, Cd, Cu) with different metal ion doped concentrations were synthesized by sol-gel method. The structural and optical properties were characterized by UVâVis spectroscopy and Fourier transform infrared (FT-IR).

FEBS Letters, EarlyView.The S1025 peptide is the major antidote to the YrzI toxin, which we renamed here as SpyT (Small Peptide YrzI Toxin) and SpyA (Small Peptide YrzI Antitoxin) (1). Degradation of the toxin–antitoxin spyTA mRNA, either by a translation‐dependent cleavage by the endoribonuclease Rae1 (2) or by direct attack by 3′‐exoribonucleases (3), also contributes to ...

Pulse non-linear post-compression with tunable wavelength by balancing SPM and SRS [PDF]
EPJ Web of ConferencesIn non-linear pulse spectral broadening via SPM, the original central wavelength is preserved; with SRS, it is red-shifted by an amount related to the broadening. We show that, by balancing SPM and SRS, red-shift and broadening can be tuned independently.

FEBS Letters, EarlyView.Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.
