Multi-Camera AR Guidance System for Surgical Instrument Handling and Assembly: Investigating Workload and Efficiency
Announce Type: new Abstract: The handling and assembly of instruments during surgery imposes high cognitive demands on scrub nurses, particularly when instruments are unfamiliar. We present a supporting guidance system for surgical instrumentation that combines multi-camera 6D pose estimation with augmented reality in-situ visualization on a head-mounted display without the requirement for additional markers. Pose estimation and consecutive camera calibration are achieved through known objects.
Texas Instruments names insider Julie Knecht as finance chief
Texas Instruments names insider Julie Knecht as finance chief June 2 : Texas Instruments on Tuesday named insider Julie Knecht as its finance chief, succeeding Rafael Lizardi, who will retire after 25 years with the analog chipmaker. Knecht, currently chief accounting officer and vice president of accounting and tax, will assume the role on August 1, while Lizardi will take an advisory role through Aug. 31 to support the transition. CEO Haviv Ilan said Lizardi helped steer the company's...
A Lightweight Slot-Attention Framework for Multi-Instrument Multi-Pitch Estimation
Announce Type: new Abstract: Multi-pitch estimation (MPE) typically predicts which pitches are active in a mixture, but not which instrument or source produced them. This paper investigates a lightweight slot-attention framework for multi-instrument MPE (MI-MPE), where a mixture CQT is mapped to an unordered set of source-like pitch maps. The model uses permutation-invariant Hungarian matching to avoid fixed output semantics and treats the number of slots as an upper bound on the number of...
Outcome-Aware Spectral Feature Learning for Instrumental Variable Regression
Announce Type: replace-cross Abstract: We address the problem of causal effect estimation in the presence of hidden confounders using nonparametric instrumental variable (IV) regression. An established approach is to use estimators based on learned spectral features, that is, features spanning the top singular subspaces of the operator linking treatments to instruments. While powerful, such features are agnostic to the outcome variable.
Beam Instrumentation
Physics > Accelerator Physics [Submitted on 2 Jun 2026] Title:Beam Instrumentation View PDFAbstract:Beam instrumentation is known as the 'eyes and ears of a particle accelerator'. It provides the data required for the most basic operating functions such as beam steering and intensity measurement, but also for diagnosing problems and optimising performance.
Unsupervised Defect Detection for Surgical Instruments
Announce Type: replace Abstract: Ensuring the safety of surgical instruments requires reliable detection of visual defects. However, manual inspection is prone to error, and existing automated defect detection methods, typically trained on natural/industrial images, fail to transfer effectively to the surgical domain. We demonstrate that simply applying or fine-tuning these approaches leads to issues: false positive detections arising from textured backgrounds, poor sensitivity to small,...
Distributed Instrument Simulation with Quantum Side Information in the One-Shot Regime
arXiv:2109.12586v5 Announce Type: replace-cross Abstract: Three distributed parties, two transmitters (Txs) and a receiver (Rx), hold one component each of a tripartite quantum state \(\rho^{A_1A_2C}\). The goal is to simulate the action of a separable instrument acting on the \(A_1\) and \(A_2\) components, with the Rx recovering the classical outcome. To enable this, each Tx \(k\) can transfer bits on a noiseless bit pipe and share randomness at rates \(R_k\) and \(C_k\), respectively,...
Gintė Preisaitė: Instruments of Forgetting and the Singing Bone review | Safi Bugel's experimental album of the month
(Felt)From birdsong to pool balls, this Lithuanian musician – a graduate of Copenhagen’s buzzy Rhythmic Music Conservatory – mixes beguiling found sounds into left-field pop and modern classicalCopenhagen’s Rhythmic Music Conservatory has become associated with a specific gauzy, esoteric sound, which draws on, and reshapes, classical instrumentation and pop songwriting. Think ML Buch, Astrid Sonne and Erika de Casier, all of whom have graduated from the institution since 2019. Following in...
LAP: An Agent-to-Instrument Protocol for Autonomous Science
Announce Type: new Abstract: Autonomous science is moving from demonstration to infrastructure. Large language model agents now plan experiments, and self-driving laboratories execute them. Yet every such system rebuilds the link between the reasoning agent and the physical instrument from scratch, against fragmented vendor SDKs and standards built for deterministic software clients rather than probabilistic, goal-directed agents.
