Mine overview
A large limestone mine was selected as the research object. The mining area is located in the basement layer of the Weilong-Zhangwu Basin, within the northwest-west trending structural belt, at the core of the Yihuqiao syncline. The…

Near-infrared [P II] and [Fe II] Emission-line Study of Supernova Remnants in the Magellanic Clouds
We report findings from near-infrared imaging observations of 17 young and middle-aged supernova remnants (SNRs) in the Magellanic Clouds to examine the impact of SNR shocks on dust destruction and the possible detection of supernova ejecta. We…

Efficient and practical Hamiltonian simulation from time-dependent product formulas
THRIFT algorithms
Consider a Hamiltonian of the form H = H0 + αH1 where α ≪ 1, the norms of H0 and H1 are comparable, and the unitary \({U}_{0}={e}^{-it{H}_{0}}\) can be implemented exactly for arbitrary times t with an efficient…

Demonstration of robust and efficient quantum property learning with shallow shadows
Preliminaries
We begin by reviewing the framework of randomized measurements and classical shadows. Each randomized measurement scheme is defined by an ensemble of unitary operators \({{\mathcal{E}}}\). A random unitary Ui is then sampled…

Profiling synovial tissue reveals OA subgroups
In a new study, detailed analysis of human synovial tissue led to the identification of two types of knee osteoarthritis (OA) that are associated with distinct populations of synovial fibroblasts and macrophages. The findings also implicate a…

Exploring nonlinear dynamics in periodically driven time crystal from synchronization to chaotic motion
Periodic auto-oscillations
For our studies, we have used the same ternary semiconductor structure, with which the CTC was implemented in a reservoir of In, Ga, and As nuclear spins4. The structural parameters are: A 10 μm thick epilayer of…
