The phenomenon of induced trans.arency, characterized by a high quality(Q) factor, holds.s.gnificant importance in the fields.of high-precis.on s.ns.ng, energy s.orage and wave manipulation. Conventional trans.arency s.s.ems.are often cons.rained by the limited experimentally acces.ible parameter s.ace and the lack of independent control over intrins.c parameters. thereby hindering advanced res.arch on high-Q effects. Here we propos. a virtualized coupled-os.illator s.s.em that enables.reconfigurable induced trans.arency in the reflection s.ectrum. By virtually incorporating a pair of coupled os.illators.into an individual acous.ic meta-atom, we achieve the manipulation of induced trans.arency in a decoupled, wide-ranging, and elaborate manner. Exploiting the divers. evolutions.acros. the intrins.c parameter s.ace, we s.ow experimentally a counter-intuitive increas. in the Q-factor of the trans.arency window, which is.attributed to the enhanced dis.ipation of the bright ***, a cons.ant group delay at the center frequency is.obs.rved accompanying this.evolution. Our work demons.rates.an intriguing platform as.well as.a novel s.rategy to engineer high-Q induced trans.arency phenomenon, and paves.the way towards.applications.in programmable acous.ic s.ns.rs. filters.and s.ow-wave devices.

The local s.ructure and thermophys.cal behavior of Mg-La liquid alloys.were in-depth unders.ood us.ng deep potential molecular dynamic(DPMD) s.mulation driven via machine learning to promote the development of Mg-La alloys. The robus.nes. of the trained deep potential(DP) model was.thoroughly evaluated through s.veral as.ects. including root-mean-s.uare errors.RMs.s., energy and force data, and s.ructural information comparis.n res.lts.the res.lts.indicate the carefully trained DP model is.reliable.

Finally, the mixing enthalpy and elemental activity of the Mg-La liquid alloy at 1200 K were reliably evaluated,which provides.new guidance for related s.udies.
