Dynamic Clustering and User Association in Wireless Small Cell Networks with Social Considerations
Muhammad Ikram Ashraf, Mehdi Bennis, Walid Saad +2
In this paper, a novel social network-aware user association in wireless small cell networks with underlaid device-to-device (D2D) communication is investigated. The proposed appro…
The dark side of solar photospheric G-band bright points
T. L. Riethmüller, S. K. Solanki
Bright small-scale magnetic elements found mainly in intergranular lanes at the solar surface are named bright points (BPs). They show high contrasts in Fraunhofer G-band observati…
Herschel / HIFI spectral line survey of the Orion Bar - Temperature and density differentiation near the PDR surface
Z. Nagy, Y. Choi, V. Ossenkopf-Okada +7
Photon Dominated Regions (PDRs) are interfaces between the mainly ionized and mainly molecular material around young massive stars. Analysis of the physical and chemical structure…
Derivation of Spin Torques of the Magnetic System in Broken Inversion Symmetry
H. Y. Kwon, S. P. Kang, N. J. Kim +2
We propose a new approach to derive spin torque in systems of broken inversion symmetry. It uses the concepts of asymmetric and directional spin-spin interactions to obtain their e…
Millimeter Wave V2V Communications: Distributed Association and Beam Alignment
Cristina Perfecto, Javier Del Ser, Mehdi Bennis
Recently millimeter-wave bands have been postulated as a means to accommodate the foreseen extreme bandwidth demands in vehicular communications, which result from the disseminatio…
Astrochemical Properties of Planck Cold Clumps
Ken'ichi Tatematsu, Tie Liu, Satoshi Ohashi +25
We observed thirteen Planck cold clumps with the James Clerk Maxwell Telescope/SCUBA-2 and with the Nobeyama 45 m radio telescope. The NH distribution obtained with the Nob…
Morphological properties of slender Ca II H fibrils observed by SUNRISE II
R. Gafeira, A. Lagg, Sami K Solanki +12
We use seeing-free high spatial resolution Ca II H data obtained by the SUNRISE observatory to determine properties of slender fibrils in the lower solar chromosphere. In this work…
Polynomial splittings of correction terms and doubly slice knots
Se-Goo Kim, Taehee Kim
We show that if the connected sum of two knots with coprime Alexander polynomials is doubly slice, then the Ozsváth-Szabó correction terms as smooth double sliceness obstructions v…
Spectropolarimetric evidence for a siphon flow along an emerging magnetic flux tube
Iker S. Requerey, B. Ruiz Cobo, J. C. Del Toro Iniesta +12
We study the dynamics and topology of an emerging magnetic flux concentration using high spatial resolution spectropolarimetric data acquired with the Imaging Magnetograph eXperime…
Evidence of electronic cloaking from chiral electron transport in bilayer graphene nanostructures
Kyunghoon Lee, Seunghyun Lee, Yun Suk Eo +2
The coupling of charge carrier motion and pseudospin via chirality for massless Dirac fermions in monolayer graphene has generated dramatic consequences, such as the unusual quantu…
A new MHD-assisted Stokes inversion technique
T. L. Riethmüller, S. K. Solanki, P. Barthol +10
We present a new method of Stokes inversion of spectropolarimetric data and evaluate it by taking the example of a SUNRISE/IMaX observation. An archive of synthetic Stokes profiles…
Three-dimensional structure of a sunspot light bridge
T. Felipe, M. Collados, E. Khomenko +26
Active regions are the most prominent manifestations of solar magnetic fields; their generation and dissipation are fundamental problems in solar physics. Light bridges are commonl…
Leveraging Social Communities for Optimizing Cellular Device-to-Device Communications
Md Abdul Alim, Tianyi Pan, My Tra Thai +1
Device-to-device (D2D) communications over licensed wireless spectrum has been recently proposed as a promising technology to meet the capacity crunch of next generation cellular n…
High-frequency Oscillations in Small Magnetic Elements Observed with Sunrise/SuFI
Shahin Jafarzadeh, S. K. Solanki, M. Stangalini +3
We characterize waves in small magnetic elements and investigate their propagation in the lower solar atmosphere from observations at high spatial and temporal resolution. We use t…
Estimation of the magnetic flux emergence rate in the quiet Sun from Sunrise data
H. N. Smitha, L. S. Anusha, S. K. Solanki +1
Small-scale internetwork (IN) features are thought to be the major source of fresh magnetic flux in the quiet Sun. During its first science flight in 2009, the balloon-borne observ…
Joint load balancing and interference mitigation in 5G HETNETS
Trung Kien Vu, Mehdi Bennis, Sumudu Samarakoon +2
We study the problem of joint load balancing and interference mitigation in heterogeneous networks (HetNets) in which massive multiple-input multiple-output (MIMO) macro cell base…
