Group Theory Analysis to Study Phase Transitions of Quasi-2D Sr$_{3}$Hf$_{2}$O$_{7}$ / Lora da Silva, Estelina (Porto U.) ; Gerami, Adeleh Mokhles (IPM, Tehran ; CERN) ; Neenu Lekshmi, P (Porto U.) ; Marcondes, Michel L (Sao Paulo U.) ; Assali, Lucy V C (Sao Paulo U.) ; Petrilli, Helena M (Sao Paulo U.) ; Correia, Joao Guilherme (CERN ; Lisbon U.) ; Lopes, Armandina M L (Porto U.) ; Araújo, João P (Porto U.)
We present an $ab-initio$ study performed in the framework of density functional theory, group-subgroup symmetry analysis and lattice dynamics, to probe the octahedral distortions, which occur during the structural phase transitions of the quasi-2D layered perovskite Sr$_{3}$Hf$_{2}$O$_{7}$ compound. Such a system is characterized by a high-temperature I4/mmm centrosymmetric structure and a ground-state Cmc21 ferroelectric phase. [...]

Exploitation of heterogeneous resources for ATLAS Computing / Chudoba, Jiri (Academy of Sciences of the Czech Republic, Institute of Physics) /ATLAS Collaboration
LHC experiments require significant computational resources for Monte Carlo simulations and real data processing and the ATLAS experiment is not an exception. In 2017, ATLAS exploited steadily almost 3M HS06 units, which corresponds to about 300 000 standard CPU cores. [...]

Light-harvesting features revealed by the structure of plant Photosystem I / Ben-Shem, A ; Frolow, F ; Nelson, N
Oxygenic photosynthesis is driven by two multi-subunit membrane protein complexes, Photosystem I and Photosystem II. In plants and green algae, both complexes are composed of two moieties: a reaction center (RC), where light-induced charge translocation occurs, and a peripheral antenna that absorbs light and funnels its energy to the reaction center.

LHC II system sensitivity to magnetic fluids / Cotae, Vlad ; Creanga, Ioan
Experiments have been designed to reveal the influences of ferrofluid treatment and static magnetic field exposure on the photosynthetic system II, where the light harvesting complex (LHC II) controls the ratio chlorophyll a/ chlorophyll b (revealing, indirectly, the photosynthesis rate). Spectrophotometric measurement of chlorophyll content revealed different influences for relatively low ferrofluid concentrations (10-30 mul/l) in comparison to higher concentrations (70-100 mul/l).
