Art History as Ekphrasis [PDF]

open access: yesArt History, 2010
This paper makes a case for the essentially rhetorical nature of the art-historical enterprise: description is the key act which both translates the object’s object-hood into words appropriable for art-historical argument and betrays that object-hood by making the object something other than it materially is, a word-picture.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

open access: yesAdvanced 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.
