Phase Transitions in the Pooled Data Problem

In this paper, we study the {\em pooled data} problem of identifying the labels associated with a large collection of items, based on a sequence of pooled tests revealing the counts of each label within the pool. In the noiseless setting, we identify an ex ...

A Scaling Law to Predict the Finite-Length Performance of Spatially-Coupled LDPC Codes

Rüdiger Urbanke

Spatially-coupled low-density parity-check (SC-LDPC) codes are known to have excellent asymptotic properties. Much less is known regarding their finite-length performance. We propose a scaling law to predict the error probability of finite-length spatially ...

Reconstruction and systems analysis of metabolism in apicomplexan parasites Toxoplasma gondii and Plasmodium falciparum

Stepan Tymoshenko

Understanding of metabolism in disease-causing microorganisms promotes drug design through the identification of the enzymes whose activity is indispensable for important cellular functions of the pathogens. Nowadays such understanding arises from experime ...

Form, function, and evolution of living organisms

Andrea Rinaldo, Amos Maritan

Despite the vast diversity of sizes and shapes of living organisms, life's organization across scales exhibits remarkable commonalities, most notably through the approximate validity of Kleiber's law, the power law scaling of metabolic rates with the mass ...

Analysis of adiabatic trapping for quasi-integrable area-preserving maps

Cedric Jean-François Hernalsteens, Massimo Giovannozzi

Trapping phenomena involving nonlinear resonances have been considered in the past in the framework of adiabatic theory. Several results are known for continuous-time dynamical systems generated by Hamiltonian flows in which the combined effect of nonlinea ...

Exotic blow up solutions for the $\Box u^5$-focussing wave equation in $\mathbb{R}^3$

Joachim Krieger, Roland Donninger, Min Huang

For the critical focusing wave equation

\Box u = u^5

\mathbb{R}^{3+1}

in the radial case, we construct a family of blowup solutions which are obtained from the stationary solutions

W(r)

by means of a dynamical rescaling $\lambda(t)\frac{1}{2}W(\la ...

A numerical study of droplet trapping in microfluidic devices

François Gallaire, Pierre-Thomas Paul Brun, Mathias Nagel

Microfluidic channels are powerful means of control of minute volumes such as droplets. These droplets are usually conveyed at will in an externally imposed flow which follows the geometry of the micro-channel. It has recently been pointed out by Dangla et ...

Allometric equations for non-destructive biomass estimation of early stage sugarcane plants – Case study in Pernambuco, northeastern Brazil

Hadrien Baecher

Brazil recently became the 5th world power, and with a tremendous growing of its population and the resulting needs, this country is facing challenges in providing energy to every sector of its socio-economical activity. The actual global warming concern a ...

Scaling Exponent of List Decoders with Applications to Polar Codes

Rüdiger Urbanke, Seyed Hamed Hassani, Marco Mondelli

Motivated by the significant performance gains which polar codes experience when they are decoded with successive cancellation list decoders, we study how the scaling exponent changes as a function of the list size L. In particular, we fix the block error ...

Metabolic principles of river basin organization

Andrea Rinaldo

The metabolism of a river basin is defined as the set of processes through which the basin maintains its structure and responds to its environment. Green (or biotic) metabolism is measured via transpiration and blue (or abiotic) metabolism through runoff. ...
