LARLUS: laparoscopic augmented reality from laparoscopic ultrasound
This research endeavors to improve tumor localization in minimally invasive surgeries, a challenging task primarily attributable to the absence of tactile feedback and limited visibility. The conventional solu...

Open AccessClinical evaluation of DIAGNOVIR SARS-CoV-2 ultra-rapid antigen test performance compared to PCR-based testing
Coronavirus Disease-19 (COVID-19) is a highly contagious infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The development of rapid antigen tests has contributed to...

A case series study of augmented reality in laparoscopic liver resection with a deformable preoperative model
Previous work in augmented reality (AR) guidance in monocular laparoscopic hepatectomy requires the surgeon to manually overlay a rigid preoperative model onto a laparoscopy image. This may be fairly inaccurat...

Combining Visual Cues with Interactions for 3D–2D Registration in Liver Laparoscopy
Augmented Reality (AR) in monocular liver laparoscopy requires one to register a preoperative 3D liver model to a laparoscopy image. This is a difficult problem because the preoperative shape may significantly...

Parking objects by pushing using uncalibrated visual servoing
Pushing is one of the strategies to perform robotic manipulation when the object is too large or too heavy. Motivated by this, we address the problem of how to push an object on a plane to a target pose with t...

Preoperative liver registration for augmented monocular laparoscopy using backward–forward biomechanical simulation
Augmented reality for monocular laparoscopy from a preoperative volume such as CT is achieved in two steps. The first step is to segment the organ in the preoperative volume and reconstruct its 3D model. The s...

Preliminary trial of augmented reality performed on a laparoscopic left hepatectomy
Laparoscopic liver surgery is seldom performed, mainly because of the risk of hepatic vein bleeding or incomplete resection of the tumour. This risk may be reduced by means of an augmented reality guidance sys...

A Study on Dexterous Grasps via Parallel Manipulation Analogy
This paper proposes a new approach for studying the dexterous gras** mechanisms via parallel manipulation analogy. The approach exploits the theories already developed for the dexterous robotic hands and the...

Particle-SfT: A Provably-Convergent, Fast Shape-from-Template Algorithm
The Shape-from-Template (SfT) problem is to recover the 3D shape of a deformable object from a single image, given a 3D template and a deformation constraint. We propose Particle-SfT, a new SfT algorithm which...

Deformable Registration of a Preoperative 3D Liver Volume to a Laparoscopy Image Using Contour and Shading Cues
The deformable registration of a preoperative organ volume to an intraoperative laparoscopy image is required to achieve augmented reality in laparoscopy. This is an extremely challenging objective for the liv...

Open AccessLabel-Free Biosensing with High Selectivity in Complex Media using Microtoroidal Optical Resonators
Although label-free biosensors comprised of optical microcavities inherently possess the capability of resolving molecular interactions at individual level, this extreme sensitivity restricts their convenience...

The interplay between plasma membrane and endoplasmic reticulum Ca2+ATPases in agonist-induced temporal Ca2+ dynamics
A change in the intracellular free Ca2+ concentration ([Ca2+]i) functions as a transmitter for signal transduction and shows a broad temporal pattern. Even genetically homogeneous cell types show different Ca2+ r...

Erratum: Arrays of indefinitely long uniform nanowires and nanotubes
Nature Materials 10, 494–501 (2011); published online: 12 June 2011; corrected after print: 19 July 2011. In the version of this Letter previously published, the key for Fig. 5c was incorrect. This error has n...

Arrays of indefinitely long uniform nanowires and nanotubes
Nanowires have many applications across a number of disciplines. So far, their length has been largely limited to mesoscale dimensions. Through the adaption of an iterative fibre-drawing process it is now poss...

3D object recognition using invariants of 2D projection curves
This paper presents a new method for recognizing 3D objects based on the comparison of invariants of their 2D projection curves. We show that Euclidean equivalent 3D surfaces imply affine equivalent 2D project...
