 A general algorithm for calculation of recombination losses in ionization chambers exposed to ion beams / Christensen, Jeppe brage ; Tölli, Heiki ; Bassler, Niels Dosimetry with ionization chambers in clinical ion beams for radiation therapy requires correction for recombination effects. However, common radiation protocols discriminate between initial and general recombination and provide no universal correction method for the presence of both recombination types in ion beams of charged particles heavier than protons.

 Pressure-induced phase transition and bandgap collapse in the wide-bandgap semiconductor InTaO4 / Errandonea, D ; Popescu, C ; Garg, A B ; Botella, P ; Martinez-Garcia, D ; Pellicer-Porres, J ; Rodriguez-Hernandez, P ; Munoz, A ; Cuenca-Gotor, V ; Sans, J A A pressure-induced phase transition, associated with an increase of the coordination number of In and Ta, is detected beyond 13 GPa in InTaO4 by combining synchrotron x-ray diffraction and Raman measurements in a diamond anvil cell with ab-initio calculations. High-pressure optical-absorption measurements were also carried out. [...] arXiv:1610.06739.- 2016 - 40 p. - Published in : Phys. Rev. B 93 (2016) 035204 External link: Preprint

 Monazite-type SrCrO4 under compression / Gleissner, J ; Errandonea, D ; Segura, A ; Pellicer-Porres, J ; Hakeem, M A ; Proctor, J ; Raju, S V ; Kumar, R S ; Rodriguez-Hernandez, P ; Munoz, A et al. We report a high-pressure study of monoclinic monazite-type SrCrO4 up to 26 GPa. Therein we combined x-ray diffraction, Raman and optical-absorption measurements with ab initio calculations, to find a pressure-induced structural phase transition of SrCrO4 near 8-9 GPa.

 Interplay of inhibition and multiplexing : Largest eigenvalue statistics / Ghosh, Saptarshi ; Dwivedi, Sanjiv K ; Ivanchenko, Mikhail V ; Jalan, Sarika The largest eigenvalue of a network provides understanding to various dynamical as well as stability properties of the underlying system. We investigate an interplay of inhibition and multiplexing on the largest eigenvalue statistics of networks. [...] arXiv:1610.06705.- 2016 - Published in : Europhys.

 Hydrogenated anatase: Strong photocatalytic H2 evolution without the use of a co-catalyst / Liu, Ning ; Schneider, Christopher ; Freitag, Detlef ; Venkatesan, Umamaheswari ; Marthala, V R Reddy ; Hartmann, Martin ; Winter, Benjamin ; Spiecker, Erdmann ; Zolnhofer, Eva ; Meyer, Karsten et al. In the present work we show, how a high pressure hydrogenation of commercial anatase or anatase/rutile powder can create a photocatalyst for hydrogen evolution that is highly effective and stable without the need of any additional co-catalyst. This activation effect can not be observed for rutile.

 TiO2 nanotubes: N-ion implantation at low-dose provides noble-metal-free photocatalytic H2-evolution activity / Zhou, Xuemei ; Häublein, Volker ; Liu, Ning ; Nguyen, Nhat Truong ; Zolnhofer, Eva M ; Tsuchiya, Hiroaki ; Killian, Manuela S ; Meyer, Karsten ; Frey, Lothar ; Schmuki, Patrik Low-dose nitrogen implantation induces in TiO2 nanotubes a co-catalytic activity for photocatalytic H2-evolution. The use of an ion implantation process leads to a N-implanted zone only at the top part of the tubes.

 Study on ${\Upsilon}(nS)$ ${\to}$ $B_{c}M$ decays / Sun, Junfeng ; Chen, Lili ; Wang, Na ; Huang, Jinshu ; Yang, Yueling ; Chang, Qin With anticipation of abundant Upsilons data sample at high-luminosity heavy-flavor experiments in the future, we studied nonleptonic two-body weak decays of ${\Upsilon}(nS)$ below the open-bottom threshold with $n$ $=$ $1$, $2$ and $3$. It is found that branching ratios for ${\Upsilon}(1S,2S,3S)$ ${\to}$ $B_{c}{\rho}$ decays are relatively large among upsilons decay into $B_{c}M$ final states ($M$ $=$ ${\pi}$ ${\rho}$, $K$ and $K^{\ast}$) and can reach up to $10^{-10}$, which is promisingly detected by experiments at the running LHC and forthcoming SuperKEKB.. arXiv:1610.06723.- 2016 - 12 p. - Published in : Nucl.

 Study on the ${\Upsilon}(1S)$ ${\to}$ $B_{c}M$ weak decays / Sun, Junfeng ; Chen, Lili ; Wang, Na ; Chang, Qin ; Huang, Jinshu ; Yang, Yueling Motivated by the prospects of the potential ${\Upsilon}(1S)$ particle at high-luminosity heavy-flavor experiments, we studied the ${\Upsilon}(1S)$ ${\to}$ $B_{c}M$ weak decays, where $M$ $=$ ${\pi}$, ${\rho}$, $K^{(\ast)}$. The nonfactorizable contributions to hadronic matrix elements are taken into consideration with the QCDF approach.

The performance of the Time Projection Chamber (TPC) polarimeter for the Polarimeter for Relativistic Astrophysical X-ray Sources (PRAXyS) Small Explorer was evaluated using polarized and unpolarized X-ray sources. The PRAXyS mission will enable exploration of the universe through X-ray polarimetry in the 2-10 keV energy band.

 Theoretical Study Of The Effects Of Magnetic Field Geometry On The High-Energy Emission Of Blazars / Joshi, Manasvita ; Marscher, Alan P ; Boettcher, Markus The knowledge of the structure of the magnetic field inside a blazar jet, as deduced from polarization observations at radio to optical wavelengths, is closely related to the formation and propagation of relativistic jets that result from accretion onto supermassive black holes. However, a largely unexplored aspect of the theoretical understanding of radiation transfer physics in blazar jets has been the magnetic field geometry as revealed by the polarized emission and the connection between the variability in polarization and flux across the spectrum.
