The ultimate and proximate mechanisms driving the evolution of long tails in forest deer mice
Understanding both the role of selection in driving phenotypic change and its underlying genetic basis remain major challenges in evolutionary biology. Here, we use modern tools to revisit a classic system of local adaptation in the North American deer mou ...
Wiley2017Avalanches in dry and saturated disordered media at fracture
Jean-François Molinari, Enrico Milanese, Okan Yilmaz
This paper analyzes fracturing in inhomogeneous media under dry and fully saturated conditions. We adopt a central force model with continuous damage to study avalanche behavior in a two-dimensional truss lattice undergoing dilation. Multiple fractures can ...
Amer Physical Soc2016An Analysis of Load Imbalance in Scale-out Data Serving
Babak Falsafi, Edouard Bugnion, Boris Robert Grot, Alexandros Daglis, Stanko Novakovic
Despite the natural parallelism across lookups, performance of distributed key-value stores is often limited due to load imbalance induced by heavy skew in the popularity distribution of the dataset. To avoid violating service level objectives expressed in ...
2016On Designing An Active Tail For Body-Pitch Control In Legged Robots Via Decoupling Of Control Objectives
Auke Ijspeert, Massimo Vespignani, Mostafa Ajallooeian, Peter Eckert, Steve Walter Shue Heim
This work explores the use of active tails for steady-state legged-locomotion. Simple models are proposed which capture the dynamics of an idealized running system with an active tail. Analysis suggests that the control objectives of injecting energy into ...
World Scientific Publ Co Pte Ltd2016Monitoring-based safety verification at the Ultimate Limit State of fracture of the RC slab of a short span railway underpass
Eugen Brühwiler, Vasileios Grigoriou
The examination value of the railway traffic action effect is calculated from long-term monitoring data without resorting to load models and structural analysis. Monitoring data are obtained from measurements on a short span RC slab bridge. The action effe ...
Elsevier Science Bv2016The Case for RackOut: Scalable Data Serving Using Rack-Scale Systems
Babak Falsafi, Edouard Bugnion, Boris Robert Grot, Alexandros Daglis, Stanko Novakovic
To provide low latency and high throughput guarantees, most large key-value stores keep the data in the memory of many servers. Despite the natural parallelism across lookups, the load imbalance, introduced by heavy skew in the popularity distribution of k ...
2016Dual sourcing under heavy-tailed demand: an extreme value theory approach
We consider a single-period dual-sourcing problem in which a buyer purchases its products from two different suppliers and sells them to a market with uncertain demand. One supplier is cheaper but less responsive, whereas the other supplier is more respons ...
Taylor & Francis Ltd2015Continuum percolation of polydisperse hyperspheres in infinite dimensions
We analyze the critical connectivity of systems of penetrable d-dimensional spheres having size distributions in terms of weighed random geometrical graphs, in which vertex coordinates correspond to random positions of the sphere centers, and edges are for ...
Amer Physical Soc2015Social-Aware Replication in Geo-Diverse Online Systems
Distributing long-tail content is a difficult task due to the low amortization of bandwidth transfer costs as such content has limited number of views. Two recent trends are making this problem harder. First, the increasing popularity of user-generated con ...
Institute of Electrical and Electronics Engineers2015A Scaling Law to Predict the Finite-Length Performance of Spatially-Coupled LDPC Codes
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 ...
