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

Physics Prospects at the HL-LHC with ATLAS [PDF]

, 2017
The High-Luminosity LHC aims to provide a total integrated luminosity of 3000 fb−1 from proton-proton collisions at √ s = 14 TeV over the course of ∼ 10 years, reaching instantaneous luminosities of up to L = 7.5 × 1034cm−2 s −1 , corresponding to

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.

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 ...

HL-LHC Analysis With ROOT

, 2022
ROOT is high energy physics' software for storing and mining data in a statistically sound way, to publish results with scientific graphics. It is evolving since 25 years, now providing the storage format for more than one exabyte of data; virtually all high energy physics experiments use ROOT. With another significant increase in the amount of data to

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 ...

Moderate Temperature Reduction Changes the High-Light Acclimation Strategy of Lettuce Plants. [PDF]

Physiol Plant
ABSTRACT In nature, environmental conditions are constantly changing, requiring plants to have numerous regulatory mechanisms to keep light harvesting and metabolism in balance. Here, we show that high light (HL) induces a much stronger non‐photochemical quenching (NPQ) when lettuce plants are exposed to 1500 μmol photons m−2 s−1 for 4 h at 13°C (low ...

Analysis Facilities for HL-LHC

, 2022
The HL-LHC presents significant challenges for the HEP analysis community. The number of events in each analysis is expected to increase by an order of magnitude and new techniques are expected to be required; both challenges necessitate new services and approaches for analysis facilities.
