This paper presents an equivalence result between computability in the BSS model and in a suitable distributive category.  ...  It is proved that the class of functions R' + R" (with 1, m finite and R a commutative, ordered ring) computable in the BSS model and the functions distributively computable over a natural distributive  ...  Acknowledgement The author would like to thank Paolo P. Boldi for many useful discussions and suggestions.  ...

Statistical mechanics of wind wave-induced erosion in shallow tidal basins: Inferences from the Venice Lagoon

Andrea D'Alpaos, Luca Carniello, Andrea Rinaldo
2013 Geophysical Research Letters  
Here we have employed a complete, coupled finite element model accounting for the role of wind waves and tidal currents on the hydrodynamic circulation in shallow basins to analyze the characteristics  ...  The results of our analyses from the Venice Lagoon suggest that wind wave-induced resuspension events can be modeled as a marked Poisson process, thus allowing one to set up a theoretical framework which  ...  This work was supported by the CARIPARO Project titled "Reading signatures of the past to predict the future: 1000 years of stratigraphic record as a key for the future of the Venice Lagoon."  ...

On the $\alpha$-Stable Distribution of Base Stations in Cellular Networks

Yifan Zhou, Rongpeng Li, Zhifeng Zhao, Xuan Zhou, Honggang Zhang
2015 IEEE Communications Letters  
In particular, α-stable distribution, the distribution also found in traffic pattern of broadband networks and cellular networks, is most consistent with the practical one.  ...  In this letter, inspired by the clustering reality of BSs and the intrinsic heavy-tailed characteristics of human activities, we aim to re-examine the statistical pattern of BSs in cellular networks, and  ...  Consequently, in order to reduce the modeling error between Poisson distributed BSs and the practical distributed ones [4] , some variants of PPP have been exploited to obtain precise analysis results  ...

mocca code for star cluster simulations – V. Initial globular cluster conditions influence on blue stragglers

Arkadiusz Hypki, Mirek Giersz
2016 Monthly notices of the Royal Astronomical Society  
In addition, the paper presents the evolution of the ratio between the number of BSs in binaries and as single stars R_B/S. For a vast diversity of models, the ratio R_B/S approaches the value ~0.4.  ...  We find that various populations of BSs strongly depend on the initial semi-major axes distributions.  ...  Relation between hard and soft binaries Different initial semi-major axes distributions and initial clusters' concentrations have variuos influence on the populations of dynamical BSs because of (i) the  ...

The discrete logic of the Brain - Explicit modelling of Brain State durations in EEG and MEG [article]

Nelson J Trujillo-Barreto, David Araya, Wael El-Deredy
2019 bioRxiv   pre-print
These states and their transitions over time can reflect fundamental computational properties of the brain, shaping human behaviour and brain function.  ...  However, the Geometric distribution of state duration (dwell time) implicit in HMM places highest probability on very short durations, which makes it inappropriate for the accurate modelling of brain states  ...  Based on the pair-wise similarity between the maps of the two duration models, the BSs were relabelled and matched based on these maps by simple visual inspection.  ...

On the other hand, the lognormal and Weibull distributions tend to fit better the real ones in rural and coastal scenarios.  ...  Based on a thorough comparison with real data sets, our results clearly assess that the α-Stable distribution is the most accurate one among the other candidates in urban scenarios.  ...  Moreover, the RMSE of the other distributions (i.e., Lognormal, generalized Pareto, Weibull) is always between the one of the Poisson distribution and the α-Stable fitting.  ...
