Loss of qE Does Not Necessarily Lead to Photoinhibition: Sustained Non-Photochemical Quenching in the Absence of PsbS and Zeaxanthin. [PDF]

Plant Cell Environ
ABSTRACT Photosynthetic light‐harvesting complexes mediate light absorption and energy dissipation. By modulating the photosystems' absorption cross‐section, they affect both photosynthetic activity and non‐photochemical quenching (NPQ). These processes are often studied by spectrally integrated chlorophyll fluorescence, masking their associated ...

Static and dynamic acclimation mechanisms to extreme light intensities in Hedera helix (Ivy) plants. [PDF]

Physiol Plant
Abstract Under natural conditions, plants face the need to acclimate to widely varying light intensities to optimize photosynthetic efficiency and minimize photodamage. Studying the mechanisms underlying these acclimation processes is essential for understanding plant productivity and resilience under fluctuating environmental conditions.

First demonstration of the use of crab cavities on hadron beams

Physical Review Accelerators and Beams, 2021
Many future particle colliders require beam crabbing to recover geometric luminosity loss from the nonzero crossing angle at the interaction point (IP). A first demonstration experiment of crabbing with hadron beams was successfully carried out with high

Thermal and supply voltage analysis of optimized ring oscillator for pixel detector readout chip [PDF]

مجلة جامعة النجاح للأبحاث العلوم الطبيعية
This paper provides a specific study of the upgrade of the ATLAS pixel detector in preparation for the upgrade of the Large Hadron Collider (LHC). The upgrade to High Luminosity-LHC (HL-LHC) is expected to start after the long shutdown in 2025-2027.

Higgs Physics at HL-LHC

, 2023
The large dataset of about 3000 fb$^{-1}$ that will be collected by both the ATLAS and CMS experiments at the High Luminosity LHC (HL-LHC) will be used to measure Higgs boson properties in detail. Studies based on current analyses have been carried out to understand the expected precision and limitations of these measurements.

CMS Computing Resources: Meeting the demands of the high-luminosity LHC physics program [PDF]

EPJ Web of Conferences, 2019
The high-luminosity program has seen numerous extrapolations of its needed computing resources that each indicate the need for substantial changes if the desired HL-LHC physics program is to be supported within the current level of computing resource ...

Achromatic telescopic squeezing scheme and by-products: From concept to validation

Physical Review Accelerators and Beams, 2021
The achromatic telescopic squeezing (ATS) scheme has brought an essential conceptual foundation to the HL-LHC project, making possible a strong and clean (achromatic) reduction of β^{*}, an important parameter with respect to which several HL-LHC sub ...

SUSY signals from QCD production at the upgraded LHC

Physics Letters B, 2019
Weak-scale supersymmetry remains to be one of the best-motivated theories of physics beyond the Standard Model. We evaluate the sensitivities of the High Luminosity (HL) and High Energy (HE) upgrades of the LHC to gluinos and stops, decaying through the ...
