Soil Silicon Application Alleviates Drought Stress in Sugar Beet (Beta vulgaris L.)

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: The increasing frequency and intensity of drought events have led to yield and quality losses in sugar beet production in temperate regions in Central Europe. Under arid conditions, silicon (Si) application reduced beet yield losses under drought. Similar data for temperate climates are missing.

PCA-based denoising method for division of focal plane polarimeters [PDF]

open access: yes, 2017
Division of focal plane (DoFP) polarimeters are composed of interlaced linear polarizers overlaid upon a focal plane array sensor. The interpolation is essential to reconstruct polarization information. However, current interpolation methods are based on

Optimization of fast spectrally encoded Mueller polarimeters for real-time monitoring [PDF]

open access: yes, 2019
International audienceIn this paper, we report a generalized theoretical framework on spectrally encoded polarimeters to display in real time both linear and circular retardance as well as linear and circular diattenuation on the basis of a recent ...

Optical Durability of Contemporary PV Encapsulants Through Artificial UV Weathering

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Encapsulant choice can be used to mitigate UV‐induced degradation in modern silicon photovoltaic modules, but this strategy is only effective if encapsulants are durable under UV weathering. This study identifies optical changes to 14 commercial encapsulants as a function of UV weathering and identifies that, while changes to material transmittance ...

Non-uniformity calibration for MWIR polarization imagery obtained with integrated microgrid polarimeters [PDF]

open access: yes, 2016
Integrating microgrid polarimeters on focal plane array (FPA) of an infrared detector causes non-uniformity of polarization response. In order to reduce the effect of polarization non-uniformity, this paper constructs an experimental setup for capturing ...

Structured decomposition design of partial Mueller matrix polarimeters [PDF]

open access: yes, 2015
Partial Mueller matrix polarimeters (pMMPs) are active sensing instruments that probe a scattering process with a set of polarization states and analyze the scattered light with a second set of polarization states.

Synergistic Mechanism Between Ir–Phosphinito Catalyst and HFIP Enables Asymmetric Hydrogenation of Ketones Under Acidic Conditions

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
A cooperative mechanism between a phosphinito Ir complex and HFIP provides a low‐energy pathway for hydrogen activation. This allowed the development of a highly efficient catalytic system for the hydrogenation of ketones that operates under acidic conditions, enabling the reduction of substrates containing phenols and carboxylic acids with no added ...

Imaging polarimetry in the LWIR with microgrid polarimeters

open access: yesEPJ Web of Conferences, 2010
Microgrid polarimeters have emerged over the past decade as a viable tool for performing real-time, highly accurate polarimetric imagery. A microgrid polarimeter operates by integrating a focal plane array (FPA) with an array of micropolarizing optics.
