Observation of strong leakage reduction in crystal assisted collimation of the SPS beam / Scandale, W (CERN ; Orsay, LAL ; INFN, Rome) ; Arduini, G (CERN) ; Butcher, M (CERN) ; Cerutti, F (CERN) ; Garattini, M (CERN) ; Gilardoni, S (CERN) ; Lechner, A (CERN) ; Losito, R (CERN) ; Masi, A (CERN) ; Mereghetti, A (CERN) et al.
In ideal two-stage collimation systems, the secondary collimator–absorber should have its length sufficient to exclude practically the exit of halo particles with large impact parameters. In the UA9 experiments on the crystal assisted collimation of the SPS beam a 60 cm long tungsten bar is used as a secondary collimator–absorber which is insufficient for the full absorption of the halo protons.

Small footprint nano-mechanical plasmonic phase modulators / Aksyuk, V A ; Dennis, B S ; Haftel, M I ; Czaplewski, D A ; Lopez, D ; Blumberg, G
The authors' recent Nature Photonics article titled "Compact Nano-Mechanical Plasmonic Phase Modulators" [1] is reviewed which reports a new phase modulation principle with experimental demonstration of a 23 {\mu}m long non-resonant modulator having 1.5 {\pi} rad range with 1.7 dB excess loss at 780 nm. Analysis showed that by decreasing all dimensions, a low loss, ultra-compact {\pi} rad phase modulator is possible. [...]

Optics of an opal modeled with a stratified effective index and the effect of the interface / Maurin, Isabelle ; Moufarej, Elias ; Laliotis, Athanasios ; Bloch, Daniel
Reflection and transmission for an artificial opal are described through a model of stratified medium based upon a one-dimensional variation of an effective index. The model is notably applicable to a Langmuir-Blodgett type disordered opal [...]

Inferences in a Virtual Community: Demography, User Preferences, and Network Topology / Pabico, Jaderick P
This paper presents a computational procedure for extracting demography data, mining patterns of human preferences, and measuring the topology of a virtual network. The network was created from the personal and relationships data of an online Internet-based community, where persons are considered nodes in the network, and relationships between persons are considered edges.

Integration of a 2D Periodic Nanopattern Into Thin Film Polycrystalline Silicon Solar Cells by Nanoimprint Lithography / Abdo, Islam ; Trompoukis, Christos ; Deckers, Jan ; Depauw, Valérie ; Tous, Loic ; Van Gestel, Dries ; Guindi, Rafik ; Gordon, Ivan ; Daif, Ounsi El
The integration of two-dimensional (2D) periodic nanopattern defined by nanoimprint lithography and dry etching into aluminum induced crystallization (AIC) based polycrystalline silicon (Poly-Si) thin film solar cells is investigated experimentally. Compared to the unpatterned cell an increase of 6% in the light absorption has been achieved thanks to the nanopattern which, in turn, increased the short circuit current from 20.6 mA/cm2 to 23.8 mA/cm2.

Cylindrical plasmas generated by an annular beam of ultraviolet light / Thomas, D M ; Allen, J E
We investigate a cylindrical plasma system with ionization, by an annular beam of ultraviolet light, taking place only in the cylinder's outer region. In the steady state, both the outer and inner regions contain a plasma, with that in the inner region being uniform and field-free. [...]

Holographic Renyi Entropies and Restrictions on Higher Derivative Terms / Pastras, Georgios ; Manolopoulos, Dimitrios
We perform a holographic calculation of the Entanglement R\'enyi entropy $S_q(\mu,\lambda)$, for spherical entangling surfaces in boundary CFT's with Einstein-Gauss-Bonnet-Maxwell holographic gravitational duals. We find that for Gauss-Bonnet couplings $\lambda$, larger than a specific value, but still allowed by causality, a violation of an inequality that R\'enyi entropies must obey by definition occurs.

Description of Heavy Quark $\overline{MS}$ Mass by Lippmann Schwinger Equation / Tazimi, N ; Monemzadeh, M ; Hadizadeh, M R
Quark masses are of great prominence in high-energy physics. In this paper, we have studied the heavy meson systems via solving the Lippmann-Schwinger equation by using the Martin potential for heavy quark masses. [...]

Results from the MINOS Experiment and New MINOS+ Data / Holin, A /MINOS for ; MINOS+ Collaborations
The MINOS experiment took data for seven years between May 2005 and April 2012. Since then it has been reborn as the new MINOS+ experiment in the upgraded medium energy NuMI beam and started taking data in September 2013. [...]

Searches for Beyond the Standard Model Physics at the LHC: Run1 Summary and Run2 Prospects / Cakir, Altan /CMS for ; ATLAS Collaborations
The search for new physics is a major goal of the LHC physics program. As excitement grows for the upcoming start of Run 2, I review the CMS and ATLAS searches for physics beyond the Standard Model from Run 1 and present recent analyses. [...]
