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 ...

Hierarchically Rough rGO/HAp Nanocoatings on SLM Ti–6Al–4 V Implants for Enhanced Biointegration

open access: yesSmall, EarlyView.
This study investigates HAp/rGO bioactive coatings on Ti‐6Al‐4V fixation implants fabricated by selective laser melting with systematically varied volumetric energy density to tailor the as‐built surface state. Composite coatings were deposited by electrophoretic deposition and characterized using micro‐CT, profilometry, FESEM/EDS, and detailed XPS to ...

Recent Advances in Oriented Hydrogels: From Fundamental Mechanisms to Future Challenges

open access: yesSusMat, EarlyView.
Traditional hydrogels suffer from weak mechanical properties and limited functionality due to their random polymer networks. This review comprehensively summarizes the reinforcement mechanisms of oriented structure for hydrogels, the design/fabrication strategies, and the latest application progress of high‐strength oriented hydrogels.

Thermomechanical modeling of motorized spindle systems for high-speed milling

open access: yes, 1997
Motorized high speed spindles with angular contact ball bearings and minimum oil lubrication may suddenly fail due to thermal problems, for which the exact reason is unknown.

Characteristics of motorized spindle supported by active magnetic bearings [PDF]

open access: yes, 2014
A motorized spindle supported by active magnetic bearings (AMBs) is generally used for ultra-high-speed machining. Iron loss of radial AMB is very great owing to high rotation speed, and it will cause severe thermal deformation.

PTEN homozygous deletion is a negative prognostic factor in tumor treating fields‐treated glioblastoma, IDH wildtype patients

open access: yesBrain Pathology, EarlyView.
In a molecularly confirmed cohort of 64 newly diagnosed, TTFields‐treated glioblastomas, IDH‐wildtype, homozygous PTEN deletion was associated with markedly shorter overall survival (368 vs. 603 days) and remained an independent adverse prognostic factor.

Persistent in vitro nociceptor hyperexcitability and axonal retraction produced by repeated paclitaxel doses

open access: yesThe FEBS Journal, EarlyView.
Repeated paclitaxel exposure causes long‐lasting nociceptor hyperexcitability and axonal retraction in adult sensory neurons. Using a long‐term primary nociceptor culture, we show that hyperexcitability is mediated by sequential upregulation of NaV1.8, TRPV1, TRPA1, and TRPM8 channels.
