Advanced Science, EarlyView.We report Mn‐deficient aerogels by inducing the first gelation of MnO2 nanosheets in solution using divalent metal ions as crosslinking agents, thereby inhibiting nanosheet restacking and enhancing surface utilization. Benefiting from abundant Mn vacancies and 3D porous structures, the A‐MnO2 cathode exhibits improved conductivity, fast reaction ...

Exact Discrete Stochastic Simulation With Deep‐Learning‐Scale Gradient Optimization
Advanced Science, EarlyView.A 203,796‐parameter gene regulatory network classifies handwritten digits with 98.4% accuracy using exact stochastic dynamics. The framework decouples forward simulation from backward differentiation, making continuous‐time Markov chain models compatible with deep‐learning optimization.

Dual Lineages of Langerhans Cells Cooperate to Restore the Immune Barrier after Skin Injury
Advanced Science, EarlyView.After skin injury, the epidermal immune barrier is rebuilt by two sources of Langerhans cells. Resident Langerhans cells first move into the wound during re‐epithelialization, guided by CXCR2 signaling. Later, recruited monocytes become long‐lived Langerhans cells.

Improvements to the Psi-SSA representation [PDF]
Proceedingsof the 10th international workshop on Software & compilers for embedded systems - SCOPES '07, 2007 Modern compiler implementations use the Static Single Assignment representation as a way to efficiently implement optimizing algorithms. However this representation is not well adapted to architectures with a predicated instruction set. The Psi-SSA representation extends the SSA representation such that standard SSA algorithms can be easily adapted to ...

Advanced Science, EarlyView.High‐mass‐loading carbon cathodes are essential for practical zinc‐ion hybrid capacitors but suffer from severe transport limitations. By combining low‐tortuosity freeze‐dried pore channels with carbon nanotube conductive networks, simultaneous optimization of ion and electron transport is achieved, enabling high‐rate, long‐life pouch cells and ...
