Background: Beta-decay spectroscopy provides valuable nuclear physics input for thermonuclear reaction rates of astrophysical interest and stringent test shell-model theories far from the stability line. Purpose: The available decay properties proton drip-line nucleus $^{27}$S is insufficient to constrain key resonance in $^{26}$Si$(p,\gamma)^{27}$P rate probe possible isospin asymmetry. scheme complicated being understood, which has motivated but also presented challenges our experiment....
$\beta$ decay of $^{26}$P was used to populate the astrophysically important $E_x=$5929.4(8) keV $J^{\pi}=3{^+}$ state $^{26}$Si. Both $\beta$-delayed proton at 418(8) and gamma ray 1742(2) emitted from this were measured simultaneously for first time with corresponding absolute intensities 11.1(12)\% 0.59(44)\%, respectively. Besides, shell model calculations weakly bound effects performed investigate properties other resonant states a spin-parity $4^+$ rather than $0^+$ favored...
Nowadays, volumetric video has emerged as an attractive multimedia application, which provides highly immersive watching experiences. However, streaming the demands prohibitively high bandwidth. Thus, effectively compressing its underlying point cloud frames is essential to deploying videos. The existing compression techniques are either 3D-based or 2D-based, but they still have drawbacks when being deployed in practice. 2D-based methods compress videos effective slow manner, while feature...
A detailed $\ensuremath{\beta}$-decay spectroscopic study of $^{22}\mathrm{Al}$ was performed at the Radioactive Ion Beam Line in Lanzhou. With $\ensuremath{\beta}\text{\ensuremath{-}}\ensuremath{\gamma}$-particle coincidence measurement by a high-resolution DSSD particle detection array and high efficiency $\ensuremath{\gamma}$-ray array, total eight excited states $^{22}\mathrm{Mg}$ fed Gamow-Teller transitions newly identified. The one-proton, two-proton, $\ensuremath{\alpha}$ decays IAS...
