Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.
Phys Rev Lett
December 2024
High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

The impact of providing additional food for predators on pest-predator dynamics, along- side pesticide use, in the IPM context remains unstudied. To address this issue, in this work a theoretical model was developed using differential equations, assuming Holling type II functional response for the predator, with additional food sources included.

- The text discusses how transferring DNA from organelles to the nucleus is crucial for the evolution of eukaryotes, highlighted by a study that identified a specific gene (BSTR) linked to photosynthesis in Populus trichocarpa.
- BSTR has three exons, with two derived from endophytic sources and one including a large part of a plastid gene related to Rubisco, which is essential for photosynthesis.
- Overexpressing BSTR in poplar and Arabidopsis plants led to significant increases in plant height (up to 200%) and biomass (up to 200%), demonstrating its potential for enhancing growth under field conditions.
Article Synopsis
- The study highlights the significant role of plant species diversity in alpine meadows on the Qinghai-Tibet Plateau, particularly in response to various levels of nitrogen addition.
- The research found that moderate nitrogen addition (30 g N/m²) improved species diversity, while excess nitrogen (60 g N/m²) led to a decline in diversity and increased competition among plant species.
- The results indicate that while grasses benefit from higher nitrogen levels, leading to increased niche width and reduced overlap with other species, this also intensifies interspecific competition and alters community dynamics.
Topological indices are the numbers that remain constant under graph automorphism. Topological indices describe a network's connectivity, structure, and topological characteristics. These indices have many applications in crisp graphs.
