X-ray Source Heights in a Solar Flare: Thick-target versus Thermal Conduction Front Heating

Jeffrey W. Reep, Stephen J. Bradshaw, Gordon D. Holman

Observations of solar flares with RHESSI have shown X-ray sources traveling along flaring loops, from the corona down to the chromosphere and back up. The 28 November 2002 C1.1 fla…

Early Recognition of Emerging Flu Strain Clusters

A. Li, J. C. Phillips, M. W. Deem

Minimizing time delays in manufacturing vaccines appropriate to rapidly mutating viruses is the key step for improving vaccine effectiveness. The vaccine for the H3N2 flu type has…

Spectral Characteristics of the Unitary Critical Almost-Mathieu Operator

Jake Fillman, Darren C. Ong, Zhenghe Zhang

We discuss spectral characteristics of a one-dimensional quantum walk whose coins are distributed quasi-periodically. The unitary update rule of this quantum walk shares many spect…

Ultracold nonreactive molecules in an optical lattice: connecting chemistry to many-body physics

Andris Doçaj, Michael L. Wall, Rick Mukherjee +1

We derive effective lattice models for ultracold bosonic or fermionic nonreactive molecules (NRMs) in an optical lattice, analogous to the Hubbard model that describes ultracold at…

Spatial Phase-Sweep: Increasing temporal resolution of transient imaging using a light source array

Ryuichi Tadano, Adithya Kumar Pediredla, Kaushik Mitra +1

Transient imaging or light-in-flight techniques capture the propagation of an ultra-short pulse of light through a scene, which in effect captures the optical impulse response of t…

Spin-orbit-angular-momentum coupling in a spin-1 Bose-Einstein condensate

Li Chen, Han Pu, Yunbo Zhang

We propose a simple model with spin and orbit angular momentum coupling in a spin-1 Bose- Einstein condensate, where three internal atomic states are Raman coupled by a pair of co-…

A multi-wavelength analysis for interferometric (sub-)mm observations of protoplanetary disks: radial constraints on the dust properties and the disk structure

M. Tazzari, L. Testi, B. Ercolano +20

Theoretical models of grain growth predict dust properties to change as a function of protoplanetary disk radius, mass, age and other physical conditions. We lay down the methodolo…

Antiferromagnetism with Ultracold Atoms

Randall G. Hulet, Pedro M. Duarte, Russell A. Hart +1

We use ultracold spin--1/2 atomic fermions (Li) to realize the Hubbard model on a three-dimensional (3D) optical lattice. At relatively high temperatures and at densities near…

Experimental measurement of non-Markovian dynamics and self-diffusion in a strongly coupled plasma

T. S. Strickler, T. K. Langin, P. McQuillen +2

We present a study of the collisional relaxation of ion velocities in a strongly coupled, ultracold neutral plasma on short timescales compared to the inverse collision rate. Non-e…

Vertical Structure of Magnetized Accretion Disks around Young Stars

S. Lizano, C. Tapia, Y. Boehler +1

We model the vertical structure of magnetized accretion disks subject to viscous and resistive heating, and irradiation by the central star. We apply our formalism to the radial st…

Collective signal processing in cluster chemotaxis: roles of adaptation, amplification, and co-attraction in collective guidance

Brian A. Camley, Juliane Zimmermann, Herbert Levine +1

Single eukaryotic cells commonly sense and follow chemical gradients, performing chemotaxis. Recent experiments and theories, however, show that even when single cells do not chemo…

Measurement of differential and integrated fiducial cross sections for Higgs boson production in the four-lepton decay channel in pp collisions at sqrt(s) = 7 and 8 TeV

CMS Collaboration

Integrated fiducial cross sections for the production of four leptons via the H to 4l decays (l = e, mu) are measured in pp collisions at sqrt(s) = 7 and 8 TeV. Measurements are pe…

Identifying Seizure Onset Zone from the Causal Connectivity Inferred Using Directed Information

Rakesh Malladi, Giridhar Kalamangalam, Nitin Tandon +1

In this paper, we developed a model-based and a data-driven estimator for directed information (DI) to infer the causal connectivity graph between electrocorticographic (ECoG) sign…

Efficient Bayesian hierarchical functional data analysis with basis function approximations using Gaussian-Wishart processes

Jingjing Yang, Dennis D. Cox, Jong Soo Lee +2

Functional data are defined as realizations of random functions (mostly smooth functions) varying over a continuum, which are usually collected with measurement errors on discretiz…

Physics reach of the XENON1T dark matter experiment

The XENON collaboration, E. Aprile, J. Aalbers +113

The XENON1T experiment is currently in the commissioning phase at the Laboratori Nazionali del Gran Sasso, Italy. In this article we study the experiment's expected sensitivity to…

Distributed Phasers

Sri Raj Paul, Karthik Murthy, Kuldeep S. Meel +1

A phaser is an expressive synchronization construct that unifies collective and point-to-point coordination with dynamic task parallelism. Each task can participate in a phaser as…

Grope metrics on the knot concordance set

Tim D. Cochran, Shelly Harvey, Mark Powell

To a special type of grope embedded in 4-space, that we call an admissible grope, we associate a length function for each real number q at least 1. This gives rise to a family of p…
