A method for predicting marker tracking error
, 2007 Many Augmented Reality (AR) applications use marker-based vision tracking systems to recover camera pose by detecting one or more planar landmarks. However, most of these systems do not interactively quantify the accuracy of the pose they calculate ...

Joint Particle Filter and UKF Position Tracking in Severe Non-Line-Of-Sight Situations [PDF]
, 2009 The performance of localization techniques in a wireless communication system is severely impaired by biases induced in the range and angle measures because of the non-line-of-sight (NLOS) situation, caused by obstacles in the transmitted signal path ...

In-vitro accuracy of a novel jaw-tracking technology
Journal of Dentistry, 2023 As jaw-tracking systems integrate into digital prosthetic workflows, their accuracy remains underexplored. This study aimed to evaluate the in vitro accuracy of a novel digital jaw-tracking system (Modjaw, Villeurbanne, France) by comparing its precision and trueness to that of an industrial scanner.Upper and lower typodont models were scanned with an ...

Nanometric depth resolution from multi-focal images in microscopy [PDF]
, 2011 We describe a method for tracking the position of small features in three dimensions from images recorded on a standard microscope with an inexpensive attachment between the microscope and the camera.

Tracking emotions in the brain – Revisiting the Empathic Accuracy Task [PDF]
NeuroImage, 2018 Many empathy tasks lack ecological validity due to their use of simplistic stimuli and static analytical approaches. Empathic accuracy tasks overcome these limitations by using autobiographical emotional video clips. Usually, a single measure of empathic accuracy is computed by correlating the participants' continuous ratings of the narrator's ...

Molecular Oncology, EarlyView.Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma
Molecular Oncology, EarlyView.Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

On the accuracy of $N-1$ wire-driven parallel robots [PDF]
, 2013 A $N-1$ wire-driven parallel robot is a robot for which all the $N \ge 3$ wires are connected at the same point of the platform, allowing to control the location of this point. We are interested in the positioning accuracy of such a robot.
