Mini-UAV Based Sensory System for Measuring Environmental Variables in Greenhouses [PDF]

Sensors, 2015
This paper describes the design, construction and validation of a mobile sensory platform for greenhouse monitoring. The complete system consists of a sensory system on board a small quadrotor (i.e., a four rotor mini-UAV).

The superficial zone of articular cartilage

Inflammation and Regeneration, 2022
The superficial zone of articular cartilage contributes to smooth joint motion through the production of proteoglycan 4 (PRG4), also known as lubricin.

Cutaneous Force Feedback as a Sensory Subtraction Technique in Haptics [PDF]

D. Prattichizzo, C. Pacchierotti, G. Rosati. Cutaneous force feedback as a sensory subtraction technique in haptics. IEEE Transactions on Haptics, 5(4):289-300, 2012, 2011
A novel sensory substitution technique is presented. Kinesthetic and cutaneous force feedback are substituted by cutaneous feedback (CF) only, provided by two wearable devices able to apply forces to the index finger and the thumb, while holding a handle during a teleoperation task.

Calculation of the Coupling Coefficient in Step-Index Multimode Polymer Optical Fibers Based on the Far-Field Measurements

Frontiers in Physics, 2022
Using the power flow equation (PFE), this article investigates mode coupling in step-index (SI) multimode (MM) polymer optical fiber (POF). This equation’s coupling coefficient was initially fine-tuned so that it could appropriately reconstruct ...

Biphasic regulation of chondrocytes by Rela through induction of anti-apoptotic and catabolic target genes

Nature Communications, 2016
Rela is a transcription factor shown to have seemingly contradictory roles in anabolism and catabolism of cartilage. Here the authors find that Rela prevents chondrocyte apoptosis and that homozygous knockout causes accelerated osteoarthritis in adults ...

3D Indoor Positioning of UAVs with Spread Spectrum Ultrasound and Time-of-Flight Cameras

Sensors, 2017
This work proposes the use of a hybrid acoustic and optical indoor positioning system for the accurate 3D positioning of Unmanned Aerial Vehicles (UAVs). The acoustic module of this system is based on a Time-Code Division Multiple Access (T-CDMA) scheme,

Midterm results of revision total hip arthroplasty for migrated bipolar hemiarthroplasty in patients with hip osteoarthritis using cementless cup with the rim-fit technique

Journal of Orthopaedic Surgery, 2020
Purpose: The results of reamed bipolar hemiarthroplasty (BHA) in patients with hip osteoarthritis (OA) are reported to be unfavorable. Acetabular reaming for sufficient bony coverage caused bipolar head migration into the superomedial direction, and most

Wnt/β-catenin signaling contributes to articular cartilage homeostasis through lubricin induction in the superficial zone

Arthritis Research & Therapy, 2019
Background Both loss- and gain-of-function of Wnt/β-catenin signaling in chondrocytes result in exacerbation of osteoarthritis (OA). Here, we examined the activity and roles of Wnt/β-catenin signaling in the superficial zone (SFZ) of articular cartilage.

Nondeterministic nature of sensorineural outcomes following noise trauma

Biology Open, 2021
Over 1.1 billion individuals are at risk for noise induced hearing loss yet there is no accepted therapy. A long history of research has demonstrated that excessive noise exposure will kill outer hair cells (OHCs).
