Hedonic Prices and Quality Adjusted Price Indices Powered by AI
arXiv:2305.00044v3 Announce Type: replace-cross Abstract: We develop empirical models that efficiently process large amounts of unstructured product data (text, images, prices, quantities) to produce accurate hedonic price estimates and derived indices. To achieve this, we generate abstract product attributes (or ``fea...

Strategic Network Abandonment
arXiv:2512.24270v1 Announce Type: new Abstract: Socio-economic networks, from cities and firms to collaborative projects, often appear resilient for long periods before experiencing rapid, cascading decline as participation erodes. We explain such dynamics through a framework of strategic network abandonment, in which ...

Iterative projected gradient descent for dynamic PET kernel reconstruction
arXiv:2512.24322v1 Announce Type: new Abstract: Dynamic positron emission tomography (PET) reconstruction often presents high noise due to the use of short duration frames to describe the kinetics of the radiotracer. Here we introduce a new method to calculate a kernel matrix to be used in the kernel reconstruction for...

Impact of Angle Misalignment on the Performance of a combined Optical and millimeter-wave Transceiver enabled by a pair of Optical Harmonically Locked Lasers
arXiv:2512.24360v1 Announce Type: new Abstract: We demonstrated combined free-space optics (FSO) and D-band(110-170GHz) millimeter(mm-wave) transceiver enabled by precisely locked lasers with low phase noise. Combined capacity and tolerance to angle misalignment are studied using 100Gb/s optical and mm-wave signals.
