Design of a Novel Gripping Mechanism and Dual Manipulator Robotic System for Apple Harvesting Using Tractor

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The architecture of apple orchards can be converted to easier operation by implementing the use of a low‐cost, tractor‐mounted, dual manipulator based on a robotic harvesting system with lower degrees of freedom (DoF). To accurately avoid injuries by detecting apples, an efferent, real‐time vision system that includes a new gripping mechanism ...

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Reasoning Together or Clicking Through? Analyzing Patterns of Group Science Talk On and Off Individualized Computers

open access: yesScience Education, EarlyView.
ABSTRACT In this article, I examine group science talk within the classrooms of three urban secondary science teachers who regularly use one‐to‐one computers to mediate their NGSS‐aligned science instruction. I combine methods of framing analysis (Goffman 1974; Tannen 1993) and interaction analysis (Jordan and Henderson 1995) to illustrate differences ...

How ventures maintain stakeholder support amidst operational legitimacy threats

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary We explore how ventures mitigate operational legitimacy threats—threats that originate within the venture and challenge claims relating to the venture's ability to deliver on its promised value proposition. Through an inductive study of four ventures working to deliver their promised products following successful crowdfunding ...

Bio‐Compatible Flexible Memristive Devices Enabled by BNNT/MWCNT–ZnO Quantum Dot Hybrid Percolation Networks

open access: yesSmall, EarlyView.
BNNT rods incorporated into MWCNT–ZnO quantum dot networks regulate charge transport and suppress leakage in flexible, transparent resistive memory devices. The resulting hybrid architecture preserves nonvolatile switching under static bending and after low‐temperature exposure and subcutaneous implantation.

Scalable Room‐Temperature Terahertz Graphene Cameras

open access: yesSmall Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Space and resource use by American crow Corvus brachyrhynchos in an area endemic for chronic wasting disease

open access: yesWildlife Biology, EarlyView.
American crow Corvus brachyrhynchos is a common species throughout North America. Crows play a role in the ecology of multiple diseases and a single laboratory experiment has shown the potential for crows to pass infectious prions, such as those associated with chronic wasting disease (CWD), in their feces after being force‐fed with infected material ...

Fast scanning chip calorimetry coupled with synchrotron SAXS: an easy‐to‐use plug‐in setup for standard SAXS beamlines

open access: yesJournal of Synchrotron Radiation, EarlyView.
The custom in situ fast scanning chip calorimetry–small‐angle X‐ray scattering (SAXS) setup developed in this work enables synchronized calorimetric measurements and continuous SAXS acquisition with millisecond time resolution during ultrafast thermal protocols.
