    • D-Type Anti-Ferromagnetic Ground State in Ca₂Mn₂O₅ 

      Liu, Pan; Wang, Wei-Hua; Wang, Weichao; Cheng, Ya-Hui; Lu, Feng; Liu, Hui (IOP Publishing Ltd, 2017-02)
      We study the electronic and magnetic properties of an oxygen-deficient perovskite Ca₂Mn₂O₅ based on the first principle calculations. The calculations show that the ground state of Ca₂Mn₂O₅ is a D-type anti-ferromagnetic ...

    • Dark Photon Search in the Mass Range between 1.5 and 3.4 GeV/c² 

      Ablikim, M.; Achasov, M. N.; Ai, X. C.; Albayrak, O.; Albrecht, M.; Ambrose, D. J.; Amoroso, A.; Lou, Xinchou; BESIII Collaboration (Elsevier Science B.V., 2018-10-01)
      Using a data set of 2.93 fb⁻¹ taken at a center-of-mass energy √s = 3.773 GeV with the BESIII detector at the BEPCII collider, we perform a search for an extra U(1) gauge boson, also denoted as a dark photon. We examine ...
    • Dark Solitons with Majorana Fermions in Spin-Orbit-Coupled Fermi Gases 

      Xu, Yong; Mao, Li; Wu, Biao; Zhang, Chuanwei (American Physical Society, 2014-09-26)
      We show that a single dark soliton can exist in a spin-orbit-coupled Fermi gas with a high spin imbalance, where spin-orbit coupling favors uniform superfluids over nonuniform Fulde-Ferrell-Larkin-Ovchinnikov states, leading ...
    • Data-Driven RANS for Simulations of Large Wind Farms 

      Iungo, Giacomo V.; Viola, F.; Ciri, Umberto; Rotea, Mario A.; Leonardi, Stefano
      In the wind energy industry there is a growing need for real-time predictions of wind turbine wake flows in order to optimize power plant control and inhibit detrimental wake interactions. To this aim, a data-driven RANS ...
    • Daytime Zonal Drifts in the Ionospheric 150km and E Regions Estimated Using Ear Observations 

      Pavan Chaitanya, P.; Patra, A. K.; Otsuka, Y.; Yokoyama, T.; Yamamoto, M.; Stoneback, Russell A.; Heelis, R. A. (Amer Geophysical Union, 2017-08-31)
      Multibeam observations of the 150km echoes made using the Equatorial Atmosphere Radar (EAR), located at Kototabang, Indonesia, provide unique opportunity to study both vertical and zonal ExB plasma drifts in the equatorial ...

    • Decoupling the Influence of Surface Structure and Intrinsic Wettability on Boiling Heat Transfer 

      Dai, Xianming (Simon); Wang, P.; Yang, F.; Li, X.; Li, C.
      Surface structure and intrinsic wettability are both important for boiling heat transfer. While superhydrophilic micro, nano, and hierarchical surfaces are widely used for boiling enhancement, in which the surface structure ...
    • Decreased Segregation of Brain Systems across the Healthy Adult Lifespan 

      Chan, Micaela Y.; Park, Denise C.; Savalia, Neil K.; Petersen, Steven E.; Wig, Gagan S.
      Healthy aging has been associated with decreased specialization in brain function. This characterization has focused largely on describing age-accompanied differences in specialization at the level of neurons and brain ...

    • DeepReco: Deep Learning Based Health Recommender System Using Collaborative Filtering 

      Sahoo, A. K.; Pradhan, C.; Barik, R. K.; Dubey, Harishchandra (MDPI Multidisciplinary Digital Publishing Institute, 2019-05-22)
      In today's digital world healthcare is one core area of the medical domain. A healthcare system is required to analyze a large amount of patient data which helps to derive insights and assist the prediction of diseases. ...
    • Defining Neighborhood Boundaries in Studies of Spatial Dependence in Child Behavior Problems 

      Caughy, Margaret O'Brien; Leonard, Tammy; Beron, Kurt J.; Murdoch, James C. (2013-05-03)
      Background: The purpose of this study was to extend the analysis of neighborhood effects on child behavioral outcomes in two ways: (1) by examining the geographic extent of the relationship between child behavior and ...
    • Deformation Potentials for Band-To-Band Tunneling in Silicon and Germanium from First Principles 

      Vandenberghe, William G.; Fischetti, Massimo V.
      The deformation potentials for phonon-assisted band-to-band tunneling (BTBT) in silicon and germanium are calculated using a plane-wave density functional theory code. Using hybrid functionals, we obtain: D(TA) = 4.1 x 10⁸ ...
    • Demand Dynamics in the Seasonal Goods Industry: An Empirical Analysis 

      Soysal, Gonca P.; Krishnamurthi, Lakshman
      This study develops and estimates a dynamic model of consumer choice behavior in markets for seasonal goods, where products are sold over a finite season and availability is limited. In these markets, retailers often use ...
    • Depression of the Normal-Superfluid Transition Temperature in Gated Bilayer Graphene 

      Fischetti, Massimo V.
      It is shown that the normal-superfluid transition in bilayer graphene predicted to occur at a high temperature is strongly affected not only by the dielectric constants of the substrate, interlayer, and gate insulators but ...
    • Deregulation of Mitochondrial F1FO-ATP Synthase via OSCP in Alzheimer's Disease
