NOETHER: A Constructive Framework for Metamorphic Pattern Discovery from Operator Algebras

Meng Li, Xiaohua Yang, Jie Liu +1

Context. Metamorphic Testing is recognised in IEEE/ISO software-testing standards and increasingly recommended for AI systems, but its progress is bottlenecked by metamorphic relat…

A semantic mutation metric for metamorphic relation adequacy in scientific computing programs

Meng Li, Xiaohua Yang, Jie Liu +1

Context. Metamorphic Testing addresses the test-oracle problem in scientific computing, but classical Mutation Score operates on syntactic AST mutations and misses domain semantics…

Measurement of the double Dalitz decay $η \to e^{+} e^{-} e^{+} e^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using a data sample of $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with the BESIII detector, we study the rare double Dalitz decay of $η \to e^{+} e^{-} e^{+} e^{-}$ …

Amplitude Analysis of the Isospin-Violating Decay $J / ψ \to γ η π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we perform the first amplitude analysis of the process $J / ψ \to γ η π^{0}$ . The decay is dominated b…

Gravitational emissions and light curves of quasi-periodic orbits in Schwarzschild spacetime embedded in a Dehnen-type dark matter halo

Shijie Tan, Chunhua Jiang, Dan Li +3

Timelike orbits in curved spacetimes encode intrinsic information about the background geometry and serve as critical probes for investigating gravitational theories and source dis…

A high-performance cobalt-free cathode for proton-conducting solid oxide fuel cells via multi-element doping in Sr2Fe2O6

Le Zhou, Yanru Yin, Dilshod Nematov +4

The development of efficient and stable intermediate-temperature solid oxide fuel cells (SOFCs) necessitates high-performance cathode materials that are cobalt-free, cost-effective…
