Isochronous mass spectrometry has been applied to neutron-deficient $^{58}\mathrm{Ni}$ projectile fragments at the HIRFL-CSR facility in Lanzhou, China. Masses of a series short-lived ${T}_{z}=\ensuremath{-}3/2$ nuclides including $^{41}\mathrm{Ti}$, $^{45}\mathrm{Cr}$, $^{49}\mathrm{Fe}$, and $^{53}\mathrm{Ni}$ have measured with precision 20--40 keV. The new data enable us test for first time isobaric multiplet equation (IMME) $fp$-shell nuclei. We observe that IMME is inconsistent...
Abstract X-ray bursts are among the brightest stellar objects frequently observed in sky by space-based telescopes. A type-I burst is understood as a violent thermonuclear explosion on surface of neutron star, accreting matter from companion star binary system. The powered nuclear reaction sequence known rapid proton capture process (rp process), which involves hundreds exotic neutron-deficient nuclides. At so-called waiting-point nuclides, stalls until slower β + decay enables bypass. One...
Using a novel method of isochronous mass spectrometry, the masses $^{62}\mathrm{Ge}$, $^{64}\mathrm{As}$, $^{66}\mathrm{Se}$, and $^{70}\mathrm{Kr}$ are measured for first time, $^{58}\mathrm{Zn}$, $^{61}\mathrm{Ga}$, $^{63}\mathrm{Ge}$, $^{65}\mathrm{As}$, $^{67}\mathrm{Se}$, $^{71}\mathrm{Kr}$, $^{75}\mathrm{Sr}$ redetermined with improved accuracy. The new allow us to derive residual proton-neutron interactions ($\ensuremath{\delta}{V}_{pn}$) in $N=Z$ nuclei, which found decrease...
The increasing penetration of distributed generation (DG) brings about great economic and environmental benefits, while also negatively affecting the operation distribution networks due to its high intermittency. Although energy storage (DES) can effectively deal with problems caused by massive DG penetrations decoupling consumption electricity, placement DES significantly determines effectiveness capabilities. Unfortunately, existing studies are commonly based on a balanced network model,...
Masses of neutron-deficient 58Ni projectile fragments have been measured at the HIRFL-CSR facility in Lanzhou, China employing isochronous mass spectrometry technique. a series short-lived Tz = −3/2 nuclides including 45Cr nucleus with relative uncertainty about 10−6–10−7. The new turned out to be essential for modeling astrophysical rp-process. In particular, we find that formation predicted Ca–Sc cycle X-ray bursts can excluded.

Masses of $^{112}\mathrm{Sn}$ projectile fragments were measured employing isochronous mass spectrometry at the Cooler Storage Ring in Lanzhou. Different from previous data analysis method, relying on arithmetic mean revolution times stored fragments, we introduce an exponentially modified Gaussian function to describe asymmetric peak shapes.

Isochronous mass spectrometry has been applied in the storage ring CSRe to measure masses of neutron-rich $^{52--54}\mathrm{Sc}$ and $^{54,56}\mathrm{Ti}$ nuclei. The new excess values $ME(^{52}\mathrm{Sc})=\ensuremath{-}40525(65)$ keV, $ME(^{53}\mathrm{Sc})=\ensuremath{-}38910(80)$ $ME(^{54}\mathrm{Sc})=\ensuremath{-}34485(360)$ deviate from Atomic Mass Evaluation 2012 by $2.3\ensuremath{\sigma}, 2.8\ensuremath{\sigma}$, $1.7\ensuremath{\sigma}$, respectively. These large deviations...
Meta-learning deep feature embedding from an auxiliary dataset with extensive annotated samples has paved a promising avenue for few-shot open-set recognition (FSOR). However, most existing methods establish solely depending on the visual appearance of images using neural networks, which often produce obvious intra-class variation and limited generalization capacity in new FSOR tasks. To mitigate this problem, we present novel Task-aware Dual-modal Semantic Feature Learning Network (TDSNet)...
Solar prominences are very spectacular structures embedded in the tenuous and hot solar corona. The counterstreaming flows, a common feature quiescent prominences, have been discovered for more than twenty years. However, mechanism driving flows is still elusive. To unveil nature of this phenomenon, we analyzed data prominence observed by New Vacuum Telescope (NVST), Interface Region Imaging Spectrograph (IRIS), Dynamical Observatory (SDO). It found that there distinct longitudinal...
Effective proton-neutron interactions, ${V}_{pn}$, in mirror nuclei are systematically analyzed using the ground-state atomic masses. A symmetry of ${V}_{pn}$ is found for bound with a standard deviation $\ensuremath{\sigma}=32$ keV. However, this apparently broken some mirror-nuclei pairs when proton-unbound nucleus involved extracting values. Such mirror-symmetry breaking attributed to Thomas-Ehrman shift and investigated by Gamow shell model. It concluded that originates mainly from...
