Detecting Grapevine Virus Infections in Red and White Winegrape Canopies Using Proximal Hyperspectral Sensing

Sensors, 2023
Grapevine virus-associated disease such as grapevine leafroll disease (GLD) affects grapevine health worldwide. Current diagnostic methods are either highly costly (laboratory-based diagnostics) or can be unreliable (visual assessments).

Scientific Objectives, Measurement Needs, and Challenges Motivating the PARAGON Aerosol Initiative [PDF]

, 2004
Aerosols are involved in a complex set of processes that operate across many spatial and temporal scales. Understanding these processes, and ensuring their accurate representation in models of transport, radiation transfer, and climate, requires ...

Lead‐Free Tin‐Based Perovskite LEDs Toward Rec. 2020: Organic Anion Coordination for Oxidation Suppression

Advanced Science, EarlyView.
This study introduces an organic anion‐coordination for oxidation suppression (OCOS) strategy using alkali metal–organic anions (e.g., KEtO) to stabilize Sn2+ in lead‐free Sn‐based perovskites for PeLEDs. By coordinating with Sn2+ and inhibiting vacancies, OCOS enhances film quality, EQE (to 10.01% at 638 nm), and luminance (to 139.9 cd m−2 ...

Detection of grapevine leaf stripe disease symptoms by hyperspectral sensor

Phytopathologia Mediterranea, 2018
Hyperspectral sensors can measure reflectance in a wide range of the electromagnetic spectrum. These can be used as an indirect method for detecting plant disease, by comparing the specific spectral signatures between symptomatic and asymptomatic ...

TLS-bridged co-prediction of tree-level multifarious stem structure variables from worldview-2 panchromatic imagery: a case study of the boreal forest [PDF]

, 2016
In forest ecosystem studies, tree stem structure variables (SSVs) proved to be an essential kind of parameters, and now simultaneously deriving SSVs of as many kinds as possible at large scales is preferred for enhancing the frontier studies on ...

A Hybrid Photocatalyst Panel Consisting of a Molecular Ru(II) Complex, Polymeric Carbon Nitride, and Titania for Visible‐Light CO2 Reduction

Advanced Energy and Sustainability Research, EarlyView.
A hybrid photocatalyst panel consisting of a Ru(II) complex, polymeric carbon nitride, and titania is fabricated on a glass substrate. Under visible light and in the presence of triethanolamine as an electron donor, it catalyzes CO2‐to‐HCOOH conversion in a nonaqueous environment, achieving an apparent quantum yield of 2.0% at 400 nm and 85 ...

Optoelectronic Neuromorphic System Based on Amorphous Indium–Gallium–Zinc–Oxide Thin‐Film Transistor for Spiking Neural Networks

Advanced Intelligent Systems, EarlyView.
An amorphous indium–gallium–zinc–oxide (IGZO)‐based optoelectronic neuromorphic system integrating light guides is introduced. The IGZO‐based optoelectronic synaptic transistor demonstrates high retention through a negative gate bias and emulates synaptic plasticity.

Estimating Cotton Nitrogen Nutrition Status Using Leaf Greenness and Ground Cover Information

Remote Sensing, 2015
Assessing nitrogen (N) status is important from economic and environmental standpoints. To date, many spectral indices to estimate cotton chlorophyll or N content have been purely developed using statistical analysis approach where they are often subject

Shortwave Spectroradiometer (SWS) Handbook [PDF]

, 2006
The Shortwave Spectroradiometer (SWS), measures the absolute visible and near infrared spectralradiance (units of watts per meter square per nanometer per steradian) of the zenith directly above the instrument. The SWS is a moderate resolution sensor comprised of two Zeiss spectrometers (MMS 1 NIR enhanced and NIR-PGS 2.2) for visible and near-infrared

Effects of Ambient and Display Lighting Color on Risk‐Taking Behavior, Perceived Emotional States, and Visual Quality of Indoor Environment

Color Research &Application, EarlyView.
In a digital risk‐taking test, participants inflated a balloon to increase earned points at the risk of popping under different display and ambient lighting conditions. ABSTRACT Lighting from architectural fixtures and screens can have impacts beyond visual perception, such as occupants' cognitive functions and emotional states. Despite the ubiquity of
