Advanced Engineering Materials, EarlyView.Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Advanced Engineering Materials, EarlyView.X‐ray computed tomography reveals how process‐induced defects evolve from green to sintered states in Fused Filament Fabrication (FFF)‐manufactured 17‐4PH stainless steel. Internal porosity, weakest cross‐sections, and fracture locations show strong correlation with tensile performance, demonstrating the potential of computed tomography (CT)‐based ...

Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

For a positive operator A acting on a Hilbert space, the shorted operator $\mathcal{L}( A )$ is defined to be the supremum of all positive operators which are smaller than A and which have range lying in a fixed subspace S. This maximization problem arises naturally in electrical network theory.

The Shorted Operator Statistically Interpreted
Calcutta Statistical Association Bulletin, 1990ABSTRACT: The object of this paper is to point out that the shorted positive operator (Krein (1947), Anderson and Trapp (1975) can be looked upon as the disperson matrix of the BLUE of EY when the random vector Y is subject ro a linear model.

Post-operative shortness of breath
Emergency Medicine Journal, 2017A previously well 34-year-old woman presented to the ED in the evening following an elective arthroscopy of her right shoulder and removal of a paralabral cyst. She had undergone a general anaesthetic and right interscalene nerve block, and the operation had gone well.
