Monsters of finance

American Ethnologist, EarlyView.
Abstract An anthropology of horror can serve as a vernacular critique of financial speculation. Drawing on fieldwork in San Pedro, Paraguay, I track horror across three registers: pombero tricksters; plata yvyguy (buried money) as a founding myth of postwar finance; and obligations binding sesame farmers to monsters, patrones, and creditors.

Inductive Biases in Field-level Cosmological Inference from Galaxy Catalogs

The Astrophysical Journal
We perform field-level likelihood-free inference of the matter density parameter Ω _m from simulated galaxy catalogs using machine learning models with differing inductive biases.

Large scale structure as a probe of gravitational slip [PDF]

, 2008
A new time-dependent, scale-independent parameter, ϖ, is employed in a phenomenological model of the deviation from general relativity in which the Newtonian and longitudinal gravitational potentials slip apart on cosmological scales as dark energy ...

Topology‐based Visual Analysis of Hydrothermal Plumes

Computer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

Learning the Universe with Cosmological Rescaling of Merger Trees and Semianalytic Galaxy Formation Models

The Astrophysical Journal
Learning cosmology from galaxy surveys requires large suites of simulations spanning the cosmological and astrophysical parameter space, yet hydrodynamical simulations of galaxy formation remain prohibitively expensive.

Constraints on cosmological parameters from MAXMIA-1

, 2002
Using the angular power spectrum of the cosmic microwave background measured over a wide range of ℓ in the first flight of the MAXIMA balloon-borne experiment (MAXIMA-1) and the low ℓ results from COBE/DMR, we set constraints on a suite of cosmological ...

Scalable Computation of Topological Abstractions for Scalar Data

Computer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Participatory Science and Machine Learning Applied to Millions of Sources in the Hobby–Eberly Telescope Dark Energy Experiment

The Astrophysical Journal
We are merging a large participatory science effort with machine learning to enhance the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX). Our overall goal is to remove false positives, allowing us to use lower signal-to-noise data and sources with

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

Meteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the
