Benchmarking the ORCA PT-2 Boson Sampler using Minimum Dominating Set Problems
arXiv:2605.30935v2 Announce Type: replace-cross Abstract: We use boson sampling as part of a gradient-free variational algorithm (the Binary Bosonic Solver) to solve a minimum dominating set problem and compare these results to a number of exact and heuristic classical algorithms. The boson sampling has been performed on the physical PT-2 time-bin interferometer from ORCA Computing. The PT-2 device has been tested here using both a single- and double-loop configuration and the results are...

Welfare-Optimal Classification with Accuracy Auctions
Announce Type: new Abstract: Prediction algorithms are increasingly used to inform decisions about humans, but maximizing accuracy$\rule[0.25em]{1em}{0.4pt}$the standard learning objective$\rule[0.25em]{1em}{0.4pt}$does not necessarily maximize user benefits. Instead, we propose optimizing social welfare, defined as the average gain users receive from correct predictions. Welfare enables to express, and therefore account for, heterogeneity in how much users benefit from accuracy.
Basis construction for polynomial spline spaces over arbitrary T-meshes
arXiv:2508.12950v3 Announce Type: replace Abstract : This paper presents the first method for constructing bases for polynomial spline spaces over an arbitrary T-meshes (PT-splines for short). We construct spline basis functions for an arbitrary T-mesh by first converting the T-mesh into a diagonalizable one via edge extension, ensuring a stable dimension of the spline space.
Distinguishing Photoacoustic and Photothermal Neuron Stimulation Through Quantitative Mapping Spatiotemporal Field Evolution
Neuromodulation is a rapidly advancing strategy for modulating brain function and treating neurological disorders, yet the mechanisms of optical neural stimulation remain incompletely understood. A central challenge is that photoacoustic (PA) and photothermal (PT) effects are typically generated simultaneously and evolve on overlapping spatial and temporal scales, making their contributions to neuronal activation difficult to distinguish. Here, we overcome this limitation by integrating two...
Normal forms of unidirectional coupling in quasi-phase-matched non-Hermitian systems
Announce Type: new Abstract: Optimal conditions for unidirectional coupling in quasi-phase-matched non-Hermitian systems are analyzed for both autonomous and externally driven configurations. The quasi-phase-matched coupling mechanism is due to periodic modulation of the real and imaginary parts of the coupling interface, which results in unequal coupling coefficients between interacting waves. The conventional parity-time (PT) symmetry theory suggests that the strongest unidirectionality...

Towards Blind Lens Aberration Correction via Large LensLib Pre-training and Discrete Degradation Priors
arXiv:2511.17126v4 Announce Type: replace-cross Abstract: Emerging deep-learning-based lens library pre-training (LensLib-PT) pipeline offers a new avenue for blind lens aberration correction by training a universal neural network, demonstrating strong capability in handling diverse unknown optical degradations. This work proposes FoundCAC, a universal foundational framework that resolves two challenges hindering the generalization of existing pipelines: the difficulty of scaling training...
Google will livestream The Android Show: I/O Edition on May 12
Google will livestream The Android Show: I/O Edition on May 12 Google I/O is just a couple weeks away, but in keeping with a semi-recent tradition, the folks over in Mountain View are kicking things off early by live streaming the Android Show: I/O Edition on May 12 at 1PM ET/10 AM PT. While Google hasn't released many details about what it's planning to show off, the company says 2026 "is going to be one of the biggest years for Android yet."
Indonesia Asks Police to Probe Hundreds of Firms on Palm Prices
A worker of PT Gunung Sejahtera Ibu Pertiwi, an unit of Astra Agro Lestari, harvests oil palm tree fruits at the company plantation in West Kotawaringin regency, Kalimantan, Indonesia, on Tuesday, Sept. 19, 2023. At Astra Agro Lestari Tbk's unit in Central Kalimantan in Indonesia, the company works with seeds that can yield harvests by the age of 25 months after planting, much earlier that the average variety, and the company researches varieties that could keep trunks to 10 to 15 meters...
