 A quantum protective mechanism in photosynthesis / Marais, Adriana ; Sinayskiy, Ilya ; Petruccione, Francesco ; van Grondelle, Rienk Since the emergence of oxygenic photosynthesis, living systems have developed protective mechanisms against reactive oxygen species. During charge separation in photosynthetic reaction centres, triplet states can react with molecular oxygen generating destructive singlet oxygen.

 Four-wave mixing in long wavelength III-nitride QD-SOAs / Al-Khursan, Amin H ; Jbara, Ahmed S ; Abood, H I Four wave mixing analysis is stated for quantum dot semiconductor optical amplifiers (QD SOAs) using the propagation equations (including nonlinear propagation contribution) coupled with the QD rate equations under the saturation assumption. Long wavelength III-nitride InN and AlInN QD SOAs are simulated. [...] arXiv:1602.01546.- 2016 - 8 p. - Published in : October 1 (2013) 4 External link: Preprint

 New Astrophysical Reaction Rate for the $^{12}\textrm{C}(\alpha,\gamma)^{16}\textrm{O}$ Reaction / An, Z D ; Ma, Y G ; Fan, G T ; Li, Y J ; Chen, Z P ; Sun, Y Y A new astrophysical reaction rate for $^{12}$C($\alpha,\gamma$)$^{16}$O has been evaluated on the basis of a global R-matrix fitting to the available experimental data. The reaction rates of $^{12}$C($\alpha,\gamma$)$^{16}$O for stellar temperatures between 0.04 $\leq$ $T_9$ $\leq$ 10 are provided in a tabular form and by an analytical fitting expression.

 Detection of binary and multiple systems among rapidly rotating K and M dwarf stars from Kepler data / Oláh, Katalin ; Rappaport, Saul ; Joss, Matthew From an examination of ~18,000 Kepler light curves of K- and M-stars we find some 500 which exhibit rotational periods of less than 2 days. Among such stars, approximately 50 show two or more incommensurate periodicities. [...] arXiv:1602.01713.- 2016 - Published in : ASP Conference Series: 4 (2015) , pp. 6 External link: Preprint

 Very Hight Energy Observationa of Shell-Type Supernova Remnants with SHALON Mirror Cherenkov Telescopes / Sinitsyna, Vera G ; Sinitsyna, Vera Y The investigation of VHE gamma-ray sources by any methods, including mirror Cherenkov telescopes, touches on the problem of the cosmic ray origin and, accordingly, the role of the Galaxy in their generation. The SHALON observations have yielded the results on Galactic shell-type supernova remnants (SNR) on different evolution stages.

 Indication of the High Mass-Transfer Ratio in S-type Symbiotic Binaries / Shagatova, Natalia ; Skopal, Augustin By modelling H$^0$ column densities in eclipsing S-type symbiotic stars EG And and SY Mus, we derived the wind velocity profile and the corresponding mass-loss rate from their giants. Our analysis revealed a strong enhancement of the wind at the orbital plane.. arXiv:1602.01668.- 2016 - 2 p. - Published in : . (2015) External link: Preprint

 Slender-ribbon theory / Koens, Lyndon ; Lauga, Eric Ribbons are long narrow strips possessing three distinct material length scales (thickness, width, and length) which allow them to produce unique shapes unobtainable by wires or filaments. For example when a ribbon has half a twist and is bent into a circle it produces a M\"obius strip. [...] arXiv:1602.01268.- 2016 - Published in : Phys.

 Closed form expression for the Goos-Haenchen lateral displacement / Araujo, Manoel P ; De Leo, Stefano ; Maia, Gabriel G The Artmann formula provides an accurate determination of the Goos-Haenchen lateral displacement in terms of the light wavelength, refractive index and incidence angle. In the total reflection region, this formula is widely used in the literature and confirmed by experiments. [...] arXiv:1602.01247.- 2016 - 13 p. - Published in : Phys. Rev.

 Probing QED and fundamental constants through laser spectroscopy of vibrational transitions in HD+ / Biesheuvel, J ; Karr, J -Ph ; Hilico, L ; Eikema, K S E ; Ubachs, W ; Koelemeij, J C J The simplest molecules in nature, molecular hydrogen ions in the form of H2+ and HD+, provide an important benchmark system for tests of quantum electrodynamics in complex forms of matter. Here, we report on such a test based on a frequency measurement of a vibrational overtone transition in HD+ by laser spectroscopy.

 Kernel Architecture of the Genetic Circuitry of the Arabidopsis Circadian System / Foo, Mathias ; Somers, David E ; Kim, Pan-Jun A wide range of organisms features molecular machines, circadian clocks, which generate endogenous oscillations with ~24 h periodicity and thereby synchronize biological processes to diurnal environmental fluctuations. Recently, it has become clear that plants harbor more complex gene regulatory circuits within the core circadian clocks than other organisms, inspiring a fundamental question: are all these regulatory interactions between clock genes equally crucial for the establishment and maintenance of circadian rhythms? Our mechanistic simulation for Arabidopsis thaliana demonstrates that at least half of the total regulatory interactions must be present to express the circadian molecular profiles observed in wild-type plants.
