Using an adaptive gene network model for self-organizing multicellular behavior

Using the transient interleukin (IL)-2 secretion of effector T helper (Teff) cells as an example, we show that self-organizing multicellular behavior can be modeled and predicted by an adaptive gene network model. Incorporating an adaptation algorithm we e ...

Reclamation of low fertility soils using by-products and fast-growing trees

Marc Adami

The world population being increasing, a good energy production management is therefore necessary. Biomass production through short forest rotation by using fast-growing trees appears as a sensible way to limit fossil fuel uses. In Mediterranean regions of ...

Pre-Columbian deforestation as an amplifier of drought in Mesoamerica

Jed Oliver Kaplan

Droughts in pre-Columbian Mesoamerica caused significant societal disruptions during the Late Classic and Post-Classic Periods. While the primary causes of these droughts are still debated, it has been speculated that they may be linked to extensive defore ...

Optimal Population Codes for Space: Grid Cells Outperform Place Cells

Alexander Mathis

Rodents use two distinct neuronal coordinate systems to estimate their position: place fields in the hippocampus and grid fields in the entorhinal cortex. Whereas place cells spike at only one particular spatial location, grid cells fire at multiple sites ...

Capturing and Animating the Morphogenesis of Polygonal Tree Models

Boris Neubert

Given a static tree model we present a method to compute developmental stages that approximate the tree's natural growth. The tree model is analyzed and a graph-based description its skeleton is determined. Based on structural similarity, branches are adde ...

A randomised controlled clinical trial and gait analysis of fixed- and mobile-bearing total knee replacements with a five-year follow-up

Kamiar Aminian, Brigitte Jolles-Haeberli, Hooman Dejnabadi

This study compared the outcome of total knee replacement (TKR) in adult patients with fixed- and mobile-bearing prostheses during the first post-operative year and at five years' follow-up, using gait parameters as a new objective measure. This double-bli ...

Effects of Connectivity and Recurrent Local Disturbances on Community Structure and Population Density in Experimental Metacommunities

Andrea Rinaldo, Francesco Carrara, Florian Altermatt

Metacommunity theory poses that the occurrence and abundance of species is a product of local factors, including disturbance, and regional factors, like dispersal among patches. While metacommunity ideas have been broadly tested there is relatively little ...

Modelling prehistoric land use and carbon budgets: A critical review

Jed Oliver Kaplan

An evaluation of modelled estimates for C release following early land clearance at the global level based on new model assumptions suggests that earlier studies may have underestimated its magnitude, chiefly because of underestimation of the mid-Holocene ...

Population Size Estimation Using a Few Individuals as Agents

Martin Vetterli, Patrick Thiran, Olivier Dousse, Farid Movahedi Naini

We conduct an experiment where ten attendees of an open-air music festival are acting as Bluetooth probes. We then construct a parametric statistical model to estimate the total number of visible Bluetooth devices in the festival area. By comparing our est ...

Simulation based Population Synthesis

Michel Bierlaire, Gunnar Flötteröd, Bilal Farooq

Microsimulation of transportation and land use evolution require base year, individual characteristics and disaggregate locations of the households and persons living in the study area. On the other hand at best, the census and travel survey, which are the ...
