Cooperative bi-exponential decay of dye emission coupled via plasmons
This article demonstrates that the relaxation in the sub-radiant system leads to the population of the sub-radiant states by dephasing the super-radiant Dicke states giving rise to the bi-exponential decay in agreement with the experiments.

Atomic layer deposition of BN as a novel capping barrier for B2O3
Article demonstrating in situ deposition of BN by sequential BCl₃/NH₃ reactions at 600 K on two different oxidized boron substrates: (a) B₂O₃ deposited using BCl₃/H₂O ALD on Si at 300 K (“B₂O₃/Si”) and (b) a boron-silicon oxide formed by sequential BCl₃/O₂ reactions at 650 K on SiO₂ followed by annealing to 1000 K (“B-Si-oxide”). The data presented demonstrates that ultrathin BN films deposited by BCl₃/NH₃ ALD are promising candidates for passivation of boron oxide used in shallow doping applications.

Sarcoplasmic reticulum Ca²⁺-ATPase (SERCA) activity during the transition to endothermy in an altricial bird
Article describes SERCA activity in the pectoralis muscle and heart ventricle of red-winged blackbird (Agelaius phoeniceus) nestlings, fledglings and adults. Additionally, using a diet manipulation, the authors tested the hypothesis that muscle SERCA activity is affected by dietary fatty acid composition, as has been shown in some previous studies.

Phosphorylation of Myosin Light Chain Kinase by p21-activated Kinase PAK2
Article reporting that PAK2, a member of the Rho family of GTPase-dependent kinases, regulates isometric tension development and myosin II RLC phosphorylation in saponin permeabilized endothelial monolayers. The results demonstrate that PAK2 can directly phosphorylate MLCK, inhibiting its activity and limiting the development of isometric tension.

Approaching Bounded Rationality: From Quantum Probability to Criticality
This article discusses the decision-making model (DMM), a paradigmatic instance of criticality, which deals with bounded rationality issues in a similar way as quantum probability (QP), generating choices that cannot be accounted by classical probability (CP). This work may contribute to considering criticality as another possible fundamental pillar in order to improve the understanding of cognition and of quantum mechanics.

Survival rates in the world's southernmost forest bird community
Article asserts that the Magellanic sub-Antarctic Forest is home to the world's southernmost avian community and is the only Southern Hemisphere analogue to Northern Hemisphere temperate forests at this latitude. Authors describe annual survival patterns and their association with climate variables using a 20-year mark–recapture data set of five forest bird species in the Cape Horn Biosphere Reserve.

Gemini Near Infrared Spectrograph–Distant Quasar Survey: Prescriptions for Calibrating UV-based Estimates of Supermassive Black Hole Masses in High-redshift Quasars
Article describes how the most reliable single-epoch supermassive black hole mass (MBH) estimates in quasars are obtained by using the velocity widths of low-ionization emission lines, typically the Hβλ4861 line. The authors find that utilizing both emission lines, where available, reduces the scatter of UV-based MBH estimates by ∼15% when compared to previous studies.

Histological features of non-alcoholic fatty liver disease revealed in response to mixed vehicle emission exposure and consumption of a high-fat diet in wildtype C57Bl/6 male mice
Article describes how non-alcoholic fatty liver disease (NAFLD) is currently plaguing the population at pandemic proportions and is expected to become more prevalent over the next decade. The authors investigated the hypothesis that exposure to a mixture of gasoline and diesel engine emissions (MVE), coupled with the concurrent consumption of a HF diet, promotes the development of a NAFLD phenotype within the liver.

Early Oxidative Transformations During the Biosynthesis of Terrein and Related Natural Products
This article combines heterologous expression and in vitro studies to show that the flavin-dependent monooxygenase (FMO) TerC catalyzes the initial oxidative decarboxylation of 6-HM. The results demonstrate that the biosynthetic pathways of terrein and related(polychlorinated) congeners diverge after oxidative decarboxylation of the lactone precursor that is catalyzed by a conserved FMO and further indicate that early dehydration of the side chain is an essential step.

Article prepares and characterizes a small series of new [FeFe]-ase biomimics which contain a ferrocenyl diphosphine as a surrogate for the Fe₄S₄ moiety in the H-cluster of the enzyme. Mechanistic details of both proton reduction and H₂ oxidation have been studied by DFT allowing speculative reaction schemes to be developed.
