A Flexible and Energy‐Efficient Compute‐in‐Memory Accelerator for Kolmogorov–Arnold Networks

Advanced Intelligent Systems, EarlyView.
This article presents KA‐CIM, a compute‐in‐memory accelerator for Kolmogorov–Arnold Networks (KANs). It enables flexible and efficient computation of arbitrary nonlinear functions through cross‐layer co‐optimization from algorithm to device. KA‐CIM surpasses CPU, ASIC, VMM‐CIM, and prior KAN accelerators by 1–3 orders of magnitude in energy‐delay ...

Predictive value of seizure onset for gross motor dysfunction in individuals with pathogenic GABRB2 and GABRB3 variants

Epilepsia, EarlyView.
Abstract Objective Pathogenic variants in γ‐aminobutyric acid type A (GABAA) receptor genes have been associated with a wide spectrum of neurological disorders. We aimed to delineate the clinical trajectories associated with gain‐of‐function (GoF) and loss‐of‐function (LoF) variants in GABRB2 and GABRB3, and to develop a risk‐prediction model for gross

Mathematical Models for the Single-Channel and Multi-Channel PMU Allocation Problem and Their Solution Algorithms

Algorithms
Phasor measurement units (PMUs) are deployed at power grid nodes around the transmission grid, determining precise power system monitoring conditions. In real life, it is not realistic to place a PMU at every power grid node; thus, the lowest PMU number ...
