3D environment mapping using the Kinect V2 and path planning based on RRT algorithms [PDF]

, 2016
This paper describes a 3D path planning system that is able to provide a solution trajectory for the automatic control of a robot. The proposed system uses a point cloud obtained from the robot workspace, with a Kinect V2 sensor to identify the interest ...

Synthesis of Conjugated Linear and Cyclic Polyynes by Selective Alkyne Metathesis

Angewandte Chemie, EarlyView.
The formation of polyynes with an odd number of conjugated triple bonds is challenging, particularly for complex architectures since most established methods rely on irreversible C–C bond‐forming reactions. To address this, we have developed the synthesis of triynes via alkyne metathesis.

Batch Informed Trees (BIT*): Sampling-based Optimal Planning via the Heuristically Guided Search of Implicit Random Geometric Graphs [PDF]

, 2015
In this paper, we present Batch Informed Trees (BIT*), a planning algorithm based on unifying graph- and sampling-based planning techniques. By recognizing that a set of samples describes an implicit random geometric graph (RGG), we are able to combine ...

Hybrid RRT: A Semi-Dual-Tree RRT-Based Motion Planner [PDF]

IEEE Access, 2020
Rapidly-exploring Random Trees (RRTs) have been widely used for motion planning problems due to their ability to efficiently find solutions. Informed RRT* is an optimized version of RRT, which not only implements the rewiring process to optimize the tree but also limits the search area to a subset of the state space to return near-optimal solutions ...

Hemodynamics of Stent Implantation Procedures in Coronary Bifurcations: an in vitro study [PDF]

, 2016
Stent implantation in coronary bifurcations presents unique challenges and currently there is no universally accepted stent deployment approach. Despite clinical and computational studies, to date, the effect of each stent implantation method on the ...

Complications Associated with Continuous RRT

Kidney360, 2022
Continuous renal replacement therapy (CRRT) is a form of renal replacement therapy that is used in modern intensive care units (ICUs) to help manage acute kidney injury (AKI), end stage kidney disease (ESKD), poisonings, and some electrolyte disorders. CRRT has transformed the care of patients in the ICU over the past several decades.

Sequels of COVID-19 in nephrology. Chronic kidney patients are more prone to hemodialysis need and mortality

Journal of Infection in Developing Countries
Introduction: Acute kidney injury involves inflammation and intrinsic renal damage, and is a common complication of severe coronavirus disease 2019 (COVID-19). Baseline chronic kidney disease (CKD) confers an increased mortality risk.

Finding a needle in an exponential haystack: Discrete RRT for exploration of implicit roadmaps in multi-robot motion planning [PDF]

, 2014
We present a sampling-based framework for multi-robot motion planning which combines an implicit representation of a roadmap with a novel approach for pathfinding in geometrically embedded graphs tailored for our setting.

Nomenclature for renal replacement therapy and blood purification techniques in critically ill patients: practical applications [PDF]

, 2016
This article reports the conclusions of the second part of a consensus expert conference on the nomenclature of renal replacement therapy (RRT) techniques currently utilized to manage acute kidney injury and other organ dysfunction syndromes in ...

Cohesive sets and rainbows

, 2013
We study the strength of $\RRT^3_2$, Rainbow Ramsey Theorem for colorings of triples, and prove that $\RCA + \RRT^3_2$ implies neither $\WKL$ nor $\RRT^4_2$.
