Quantum‐Trained AI Enables Inverse Design of Organic Frontier Orbitals at Billion‐Scale
Advanced Science, EarlyView.Quantum‐trained AI links molecular substructures to frontier‐orbital energetics and enables interpretable screening across nearly one billion GDB‐13 molecules. By combining fragment‐ and ring‐level insights with donor–acceptor energy alignment against ITIC, the framework narrows an immense chemical space to a small set of promising candidates and ...

Advanced Science, EarlyView.This work illustrates that magnetic Fe substitution enables systematic modulation of physical properties of the putative unconventional superconductor Rh17S15. Iron doping uncovers delicate competition between weak ferromagnetism, spin‐glass states, heavy‐fermion signatures, and superconductivity.

Detecting Galactic Rings in the DESI Legacy Imaging Surveys with Semisupervised Deep Learning
The Astrophysical Journal Supplement SeriesThe ring structures of disk galaxies are vital for understanding galaxy evolution and dynamics. However, due to the scarcity of ringed galaxies and challenges in their identification, traditional methods often struggle to efficiently obtain statistically

Ground-based very high energy gamma ray astronomy: Observational highlights [PDF]
, 1986 It is now more than 20 years since the first ground based gamma ray experiments involving atmospheric Cerenkov radiation were undertaken. The present highlights in observational ground-based very high energy (VHE) gamma ray astronomy and the optimism ...

Advanced Science, EarlyView.Microgels enable independent control of stiffness and interstitial space, overcoming limitations of conventional 3D hydrogels. Using fragmented gelatin methacryloyl microgels, we show that stiffness does not restrict non‐metastatic breast cancer growth, contrary to bulk hydrogels, and reveal the role of adherent‐to‐suspension transition in cancer ...
