Power Grid Parameter Estimation Without Phase Measurements: Theory and Empirical Validation

Authors: Jean-Sébastien Brouillon, Keith Moffat, Florian Dörfler, Giancarlo Ferrari-trecate

arXiv

Reliable integration and operation of renewable distributed energy resources requires accurate distribution grid models. However, obtaining precise models is often prohibitively expensive, given their...

Some notable properties of the standard oncology phase I design

Authors: Gregory J. Hather, Howard Mackey

arXiv

We identify three properties of the standard oncology phase I trial design or 3 + 3 design. We show that the standard design implicitly uses isotonic regression to estimate a maximum tolerated dose....

School evasion: A hard reality

Authors: V. L. L. S. Pinto, F. A. O. Cruz

arXiv

The present work has as objective to show the profile of students who abandoned the studies in a High School, located in Sao Joao de Meriti city, municipal district of Rio de Janeiro state, by means...

Markov switching negative binomial models: an application to vehicle accident frequencies

Authors: Nataliya V. Malyshkina, Fred L. Mannering, Andrew P. Tarko

arXiv

In this paper, two-state Markov switching models are proposed to study accident frequencies. These models assume that there are two unobserved states of roadway safety, and that roadway entities (ro...

Random survival forests

Authors: Hemant Ishwaran, Udaya B. Kogalur, Eugene H. Blackstone, Michael S. Lauer

arXiv

We introduce random survival forests, a random forests method for the analysis of right-censored survival data. New survival splitting rules for growing survival trees are introduced, as is a new mi...

Inference using shape-restricted regression splines

Authors: Mary C. Meyer

arXiv

Regression splines are smooth, flexible, and parsimonious nonparametric function estimators. They are known to be sensitive to knot number and placement, but if assumptions such as monotonicity or c...

LRSA: A new computational method for analyzing time course microarray data

Authors: Wei Wu, Nilesh B. Dave, Naftali Kaminski

arXiv

Motivation: Time course data obtained from biological samples subject to specific treatments can be very useful for revealing complex and novel biological phenomena. Although an increasing number of...

Nonlinear Digital Post-Processing to Mitigate Jitter in Sampling

Authors: Daniel S. Weller, Vivek K Goyal

arXiv

This paper describes several new algorithms for estimating the parameters of a periodic bandlimited signal from samples corrupted by jitter (timing noise) and additive noise. Both classical (non-ran...

A multivariate phase distribution and its estimation

Authors: Charles F. Cadieu, Kilian Koepsell

arXiv

Circular variables such as phase or orientation have received considerable attention throughout the scientific and engineering communities and have recently been quite prominent in the field of neur...

To which extend is the "neural code" a metric ?

Authors: Bruno Cessac, Horacio Rostro-González, Juan-Carlos Vasquez, Thierry Viéville

arXiv

Here is proposed a review of the different choices to structure spike trains, using deterministic metrics. Temporal constraints observed in biological or computational spike trains are first taken i...

Introducing numerical bounds to improve event-based neural network simulation

Authors: Bruno Cessac, Olivier Rochel, Thierry Viéville

arXiv

Although the spike-trains in neural networks are mainly constrained by the neural dynamics itself, global temporal constraints (refractoriness, time precision, propagation delays, ..) are also to be...

Correlated connectivity and the distribution of firing rates in the neocortex

Authors: Alexei Koulakov, Tomas Hromadka, Anthony M. Zador

arXiv

Two recent experimental observations pose a challenge to many cortical models. First, the activity in the auditory cortex is sparse, and firing rates can be described by a lognormal distribution. Se...

Mechanism, dynamics, and biological existence of multistability in a large class of bursting neurons

Authors: J. P. Newman, R. J. Butera

arXiv

Multistability, the coexistence of multiple attractors in a dynamical system, is explored in bursting nerve cells. A modeling study is performed to show that a large class of bursting systems, as defi...

Topological Effects of Synaptic Time Dependent Plasticity

Authors: James R. Kozloski, Guillermo A. Cecchi

arXiv

We show that the local Spike Timing-Dependent Plasticity (STDP) rule has the effect of regulating the trans-synaptic weights of loops of any length within a simulated network of neurons. We show that...

Mental States as Macrostates Emerging from EEG Dynamics

Authors: Carsten Allefeld, Harald Atmanspacher, Jiri Wackermann

arXiv

Correlations between psychological and physiological phenomena form the basis for different medical and scientific disciplines, but the nature of this relation has not yet been fully understood. One...
