Self localization and mapping using optical and thermal imagery [PDF]
, 2011 Given a mobile robot starting from an unknown position in an unknown environment, with the task of explores the surroundings, it has to be able to build an environmental map and localize itself inside that map.

Collaborative Mapping for Pedestrian Navigation in Security Applications
, 2012 In rescue missions or law enforcement applications, accurate determination of every team member's position and providing this information on a map may signi cantly improve mutual situation awareness and potentially reduce the risk of accidentally ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks
Advanced Science, EarlyView.Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Line-Based Stereo SLAM by Junction Matching and Vanishing Point Alignment
IEEE Access, 2019 In this paper, we propose a stereo simultaneous localization and mapping (SLAM) method based on line segments. For the front-end module of SLAM, we designed a novel method based on the coplanar junction detection, description, and matching.

Advanced Science, EarlyView.This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Simultaneous Localization and Mapping (SLAM) using RTAB-MAP
CoRR, 2018 This paper implements Simultaneous Localization and Mapping (SLAM) technique to construct a map of a given environment. A Real Time Appearance Based Mapping (RTAB-Map) approach was taken for accomplishing this task. Initially, a 2d occupancy grid and 3d octomap was created from a provided simulated environment.

Cross-spectral visual simultaneous localization and mapping (SLAM) with sensor handover
Robotics Auton. Syst., 2013 In this work, we examine the classic problem of robot navigation via visual simultaneous localization and mapping (SLAM), but introducing the concept of dual optical and thermal (cross-spectral) sensing with the addition of sensor handover from one to ...

Slc44a2 Deficiency Unveils an IFN‐I–Dependent Feedback Control of pDC Egress
Advanced Science, EarlyView.Working model of SLC44A2‐mediated maintenance of pDC homeostasis. This model illustrates two central mechanisms by which SLC44A2 regulates pDC homeostasis: (1) SLC44A2 limits IFN‐I production by exporting amino acids (T, N, Q), thereby preventing spontaneous pDC activation.
