On the computability-theoretic complexity of trivial, strongly minimal models
computability-theoretic strongly minimal models
2015/9/28
We show the existence of a trivial, strongly minimal (and thus
uncountably categorical) theory for which the prime model is computable and
each of the other countable models computes 0
00. This res...

Borel complexity of complete, first order theories(status report).
Karp complexity and classes with the independence property
Karp complexity independence property
2015/9/25
A class K of structures is controlled if for all cardinals
λ, the relation of L∞,λ-equivalence partitions K into a set of
equivalence classes (as opposed to a proper class). We prove that
no pseudo...
Source complexity of the May 20,2012,Mw 5.9,Ferrara (Italy) event
Empirical Green's functions Array analysis
2015/8/26
A Mw 3.9 foreshock on May 19, 2012, at 23:13 UTC, was followed at 02:03 on May 20, 2012, by a Mw 5.9 earthquake that hit a densely populated area in the Po Plain, west of the city of Ferrara, Italy (F...
Filter design with low complexity coefficients
Heuristic design low complexity coefficient filters with nonzero number the filter coefficients
2015/8/10
We introduce a heuristic for designing filters that have low complexity coefficients, as measured by the total number of nonzeros digits in the binary or canonic signed digit (CSD) representations of ...
Communication Complexity and Coordination by Authority
Authority Complexity and Coordination
2015/7/31
We prove that the simplest communication allowing two players to coordinate on a course
of action is authority (letting one player choose an action). We also consider the case where
each player poss...
Simple Bounds for Recovering Low-complexity Models
`1-norm minimization nuclear-norm minimization block-sparsity duality random matrices
2015/6/17
This note presents a unified analysis of the recovery of simple objects from random linear measurements. When the linear functionals are Gaussian, we show that an s-sparse vector in Rn can be efficien...
On the complexity of surface ruptures during normal faulting earthquakes: excerpts from the 6 April 2009 L'Aquila (central Italy) earthquake (Mw 6.3)
On the complexity surface ruptures normal faulting earthquakes L'Aquila earthquake
2015/1/6
Over the past few years the assessment of the earthquake potential of large continental faults has increasingly relied on field investigations. State-of-the-art seismic hazard models are progressively...
Internal Diffusion-Limited Aggregation: Parallel Algorithms and Complexity
Internal diffusion gathered circuit subset the comparator
2014/12/22
The computational complexity of internal diffusion-limited aggregation (DLA) is examined from both a theoretical and a practical point of view. We show that for two or more dimensions, the problem of ...

high-complexity land surface model mesoscale model WRF
2014/12/19
In this study, the Weather Research and Forecasting (WRF) model is coupled with the Advanced Canopy–Atmosphere–Soil Algorithm (ACASA), a high-complexity land surface model. Although WRF is a state-of-...
Scheme for calculation of multi-layer cloudiness and precipitation for climate models of intermediate complexity
multi-layer cloudiness precipitation for climate models intermediate complexity
2014/12/12
In this study we present a scheme for calculating the characteristics of multi-layer cloudiness and precipitation for Earth system models of intermediate complexity (EMICs). This scheme considers thre...
MEDUSA-2.0: an intermediate complexity biogeochemical model of the marine carbon cycle for climate change and ocean acidification studies
MEDUSA-2.0 intermediate complexity biogeochemical model marine carbon cycle climate change ocean acidification studies
2014/12/12
MEDUSA-1.0 (Model of Ecosystem Dynamics, nutrient Utilisation, Sequestration and Acidification) was developed as an "intermediate complexity" plankton ecosystem model to study the biogeochemical respo...
Medusa-1.0: a new intermediate complexity plankton ecosystem model for the global domain
The sea is expected Plankton. Ecosystems The pump The carbon cycle. The terrestrial biosphere
2014/12/9
The ongoing, anthropogenically-driven changes to the global ocean are expected to have significant consequences for plankton ecosystems in the future. Because of the role that plankton play in the oce...
An Integrated and Evolutionary Dynamical Systems View of Climate Complexity
Climate Change Complexity System Earth
2013/3/11
The Earth shows a constant display of an organized complexity system, and its intrinsic capacity for sporadic self-organization constitutes its fundamental and profound mysterious property. A graphica...
On the Complexity of 2D Discrete Fixed Point Problem
Complexity 2D Discrete Fixed Point Problem
2012/12/3
While the 3-dimensional analogue of Sperner’s problem in the plane was known to be complete in class PPAD, the complexity of 2D-SPERNER itself is not known to be PPAD-complete or not. In this paper, w...
