Outbreak statistics and scaling laws for externally driven epidemics

Sarabjeet Singh, Christopher R. Myers

Power-law scalings are ubiquitous to physical phenomena undergoing a continuous phase transition. The classic Susceptible-Infectious-Recovered (SIR) model of epidemics is one such…

QBism as CBism: Solving the Problem of "the Now"

N. David Mermin

The QBist view of science, first put forth to dispel the fog from quantum foundations, also clears up a longstanding puzzle in classical physics.

Central role of domain wall depinning for perpendicular magnetization switching driven by spin torque from the spin Hall effect

O. J. Lee, L. Q. Liu, C. F. Pai +4

We study deterministic magnetic reversal of a perpendicularly magnetized Co layer in a Co/MgO/Ta nano-square driven by spin Hall torque from an in-plane current flowing in an under…

Consequences of an Eccentric Orbit for Fomalhaut b

Daniel Tamayo

Fomalhaut b is currently the least massive, directly imaged exoplanet candidate. New observation epochs reveal this object to be moving on a highly eccentric orbit (Kalas et al. 20…

Rounding Sum-of-Squares Relaxations

Boaz Barak, Jonathan Kelner, David Steurer

We present a general approach to rounding semidefinite programming relaxations obtained by the Sum-of-Squares method (Lasserre hierarchy). Our approach is based on using the connec…

Study of superfluid He under nanoscale confinement. A new approach to the investigation of superfluid He films

Lev Levitin, Robert Bennett, Andrew Casey +7

We review recent experiments in which superfluid He has been studied under highly controlled confinement in nanofluidic sample chambers. We discuss the experimental challenges…

A Molecular Line Scan in the Hubble Deep Field North: Constraints on the CO Luminosity Function and the Cosmic H2 Density

F. Walter, R. Decarli, M. Sargent +19

We present direct constraints on the CO luminosity function at high redshift and the resulting cosmic evolution of the molecular gas density, (z), based on a blind mole…

A molecular line scan in the Hubble Deep Field North

R. Decarli, F. Walter, C. Carilli +20

We present a molecular line scan in the Hubble Deep Field North (HDF-N) that covers the entire 3mm window (79-115 GHz) using the IRAM Plateau de Bure Interferometer. Our CO redshif…

Traveling waves for a bistable equation with nonlocal-diffusion

Franz Achleitner, Christian Kuehn

We consider a single component reaction-diffusion equation in one dimension with bistable nonlinearity and a nonlocal space-fractional diffusion operator of Riesz-Feller type. Our…

Bottomonium and B results from full lattice QCD

C. T. H. Davies, B. Colquhoun, B. Galloway +7

We have developed two methods for handling quarks in lattice QCD. One uses NRQCD (now improved to include radiative corrections) and the other uses Highly Improved Staggered Qu…

NNLL Momentum-Space Resummation for Stop-Pair Production at the LHC

Alessandro Broggio, Andrea Ferroglia, Matthias Neubert +2

If supersymmetry near the TeV scale is realized in Nature, the pair production of scalar top squarks is expected to be observable at the Large Hadron Collider. Recently, effective…

I'd Rather Stay Stupid: The Advantage of Having Low Utility

Lior Seeman

Motivated by cost of computation in game theory, we explore how changing the utilities of players (changing their complexity costs) affects the outcome of a game. We show that even…

Tricritical behavior of soft nematic elastomers

Danilo B. Liarte

We propose a lattice statistical model to investigate the phase diagrams and the soft responses of nematic liquid-crystal elastomers. Using suitably scaled infinite-range interacti…

The Smallest Particles in Saturn's A and C Rings

Rebecca A. Harbison, Philip D. Nicholson, Matthew M. Hedman

Radio occultations of Saturn's main rings by spacecraft suggest a power law particle size-distribution down to sizes of the order of 1 cm (Marouf et al., 1983), (Zebker et al., 198…
