Epipolar Geometry‐Based Visual Servoing of Soft Endoscopic Manipulator for Transoral Laser Ablation

Advanced Intelligent Systems, Volume 4, Issue 12, December 2022., 2022
A visual servoing controller is proposed, allowing automatic laser spot steering for endoscopic noncontact laser microsurgery using soft manipulators. An epipolar geometry model is established to acquire the transition mapping from image to actuation, with which a feedback controller is derived without prior information of tissue surface geometry ...

The past, present, and future of retail analytics: Insights from a survey of academic research and interviews with practitioners

Production and Operations Management, Volume 31, Issue 10, Page 3727-3748, October 2022., 2022
Abstract We document the evolution of academic research through a bibliometric analysis of 123 retail analytics articles published in top operations management journals from 2000 to 2020. We isolate nine decision areas via manual coding that we verify using automated text analysis (topic modeling).

A novel stepwise micro-TESE approach in non obstructive azoospermia [PDF]

, 2016
Background: The purpose of the study was to investigate whether micro-TESE can improve sperm retrieval rate (SRR) compared to conventional single TESE biopsy on the same testicle or to contralateral multiple TESE, by employing a novel stepwise micro ...

The geometry of trifocal curves with applications in architecture, urban and spatial planning [PDF]

Spatium, 2014
In this paper we consider historical genesis of trifocal curve as an optimal curve for solving the Fermat’s problem (minimizing the sum of distance of one point to three given points in the plane). Trifocal curves are basic plane geometric forms

Asymmetry of parietal interhemispheric connections in humans [PDF]

, 2011
Visuospatial abilities are preferentially mediated by the right hemisphere. Although this asymmetry of function is thought to be due to an unbalanced interaction between cerebral hemispheres, the underlying neurophysiological substrate is still largely ...

Tolerance to Residual Refractive Errors After Trifocal and Trifocal Toric Intraocular Lens Implantation [PDF]

Eye & Contact Lens: Science & Clinical Practice, 2020
Objective: The objective of this study was to assess the impact of 0.50 diopter (D) positive or negative defocus on visual function in patients implanted with trifocal and trifocal toric intraocular lenses (IOLs). Methods: The study included patients implanted with the AcrySof IQ ...

The Value of Static Perimetry in the Diagnosis and Follow‐up of Negative Dysphotopsia

Optometry and Vision Science, Volume 99, Issue 8, Page 645-651, August 2022., 2022
SIGNIFICANCE There is a clinical need for a quantitative test to objectively diagnose negative dysphotopsia, especially because the diagnosis is generally assessed using patients' subjective descriptions. In the search of a clinical test to objectify the shadow experienced in negative dysphotopsia, this study excludes static perimetry as suitable ...

Optimising curve fitting techniques to look for standardisation of the analysis of defocus curves derived from multifocal intraocular lenses

Ophthalmic and Physiological Optics, Volume 42, Issue 4, Page 887-896, July 2022., 2022
Abstract Introduction To establish the most appropriate curve fitting method to allow accurate comparison of defocus curves derived from intraocular lenses (IOLs). Methods Defocus curves were plotted in five IOL groups (monofocal, extended depth of focus, refractive bifocal, diffractive bifocal and trifocal).
