THERMO-NET reduces dissipation in modeled thermal systems
What the study found THERMO-NET is a physics-informed artificial intelligence framework that the authors say can model, predict, and actively suppress irreversible entropy production in several high-density computational and thermal settings. The abstract reports improved performance across five tested regimes, including quantum hardware and nano-scale thermal networks. Why the authors say this matters The authors…
Finite element scheme achieves optimal error bounds for corotational heat flow
—
in MathematicsWhat the study found The study found optimal order discretization error bounds for a finite element approximation of the corotational harmonic map heat flow problem. The analysis applies to smooth solutions of the continuous problem. Why the authors say this matters The authors indicate that the method's key analytical tools help with discrete stability and…
Nonreciprocal stiffness and damping decouple wave control in elastic lattices
—
in MechanicsNonreciprocal elastic lattices with engineered damping enable decoupled control of wave amplification and propagation, allowing independent tuning of temporal growth and velocity characteristics.
