Angewandte Chemie, EarlyView.Xanthopinacol (xpin) boronates are a conceptually new class of masked boronic acids designed to alleviate many of the disadvantages of pinacol esters and other popular adducts. They can be formed directly from xanthone and UV light, undergo orthogonal transformations, and are cleavable under photoredox catalysis or oxidative conditions that recycle ...

The MAGIC Telescope Project for Gamma Astronomy above 10 GeV [PDF]
arXiv, 1998 A project to construct a 17 m diameter imaging air Cherenkov telescope, called the MAGIC Telescope, is described. The aim of the project is to close the observation gap in the gamma-ray sky extending from 10 GeV as the highest energy measurable by space-borne experiments to 300 GeV, the lowest energy measurable by the current generation of ground-based

Compliant Robotics in Space: A Prospective Review of Soft and Deformable Systems for Space Missions
Advanced Intelligent Systems, EarlyView.Compliant robots are increasingly becoming integral to space exploration due to their adaptability, flexibility, and lightweight design. This article reviews categories such as soft, reconfigurable, and hyper‐redundant robots and their evolving role in enhancing space missions.

Advanced Intelligent Systems, EarlyView.The article develops a collaborative multirobot navigation system‐assisted magnetic catheter guidance and shape perception method using the information fusion of robotic vascular ultrasound imaging and electromagnetic tracking to reconstruct the 3D catheter's shape and vasculature. Results verify the effectiveness of the system and the potential of the

Research on Telescope TTL Coupling Noise in Intersatellite Laser Interferometry
Photonic Sensors, 2019 The detection mission of gravitational waves in space is that the accuracy of the long-baseline intersatellite laser interferometry on the million-kilometer order needs to reach the order of $$8 \rm{pm}/\sqrt{\rm{Hz}}$$ 8 p m / H z .

EUDET Telescope Geometry and Resolution Studies [PDF]
arXiv, 2007 Construction of EUDET pixel telescope will significantly improve the test beam infrastructure for the ILC vertex detector studies. The telescope, based on the Monolithic Active Pixel Sensors (MAPS), will consist of up to six readout planes and will be initially installed at an electron beam line at DESY.

American Journal of Botany, EarlyView.Abstract Premise Establishment of long‐lived perennial plants is a pivotal event that often leads to reproductive maturity. The population dynamics of the giant saguaro cactus (Carnegiea gigantea) have been investigated over large spatial areas, but establishment patterns have not been studied at the microsite (1 m) scale.

Summary of One Year Operation of the EUDET CMOS Pixel Telescope [PDF]
arXiv, 2009 Within the EUDET consortium a high resolution pixel beam telescope is being developed. The telescope consists of up to six planes of monolithic active pixel sensors. A flexible data acquisition environment is available for the telescope and the system is equipped with all the required infrastructure.

Asian Journal of Organic Chemistry, EarlyView.An interrupted Barton–Zard reaction/Friedel–Crafts alkylation telescoped reaction provides aryl‐substituted pyrrolo[3,4‐b] cores in moderate‐to‐good yields as mostly single diastereomers. The reaction is tolerant of a wide range of electron‐deficient indoles and (hetero)aromatic nucleophiles, offering a modular approach for the synthesis of multi ...
