Estimation Using Marginal Competitor Sales Information
Journal of Operations Management, EarlyView.ABSTRACT An abiding preoccupation for firms is understanding how customers value their products versus competitors' products. This is difficult to quantify and estimate from data as, even if competitor prices are public information, their sales are typically unobservable.

arXiv, 2003 A new simply constructed, easy-to-make demonstration of Hero's fountain is presented. The apparatus doesn't have a vessel above a fountain nozzle or a pump and can be considered as one of the best demonstration of Pascal and Bernoulli's principles. Its action is discussed on the basis of Pascal and Bernoulli's principles.

Update on the German and Australasian Optical Ground Station Networks
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Networks of ground stations designed to transmit and receive at visible and infra‐red wavelengths through the atmosphere offer an opportunity to provide on‐demand, high‐bandwidth, secure communications with spacecraft in Earth orbit and beyond. This work describes the operation and activities of current free space optical communications (FSOC)

Moderate deviations in random graphs and Bernoulli random matrices [PDF]
Electronic Journal of Probability, Vol. 14, 2009, Paper no. 92,
2636-2656, 2009 We prove a moderate deviation principle for subgraph count statistics of Erdos-Renyi random graphs. This is equivalent in showing a moderate deviation principle for the trace of a power of a Bernoulli random matrix. It is done via an estimation of the log-Laplace transform and the Gaertner-Ellis theorem.

Graph neural network‐based attack prediction for communication‐based train control systems
CAAI Transactions on Intelligence Technology, EarlyView.Abstract The Advanced Persistent Threats (APTs) have emerged as one of the key security challenges to industrial control systems. APTs are complex multi‐step attacks, and they are naturally diverse and complex. Therefore, it is important to comprehend the behaviour of APT attackers and anticipate the upcoming attack actions.

Scenery entropy as an invariant of RWRS processes [PDF]
arXiv, 2014 Probabilistic models of random walks in random sceneries give rise to examples of probability-preserving dynamical systems. A point in the state spaces consists of a walk-trajectory and a scenery, and its `motion' corresponds to shifting the time-origin.

Uniform uncertainty principle for Bernoulli and subgaussian ensembles [PDF]
arXiv, 2006 We present a simple solution to a question posed by Candes, Romberg and Tao on the uniform uncertainty principle for Bernoulli random matrices. More precisely, we show that a rectangular k*n random subgaussian matrix (with k < n) has the property that by arbitrarily extracting any m (with m < k) columns, the resulting submatrices are arbitrarily close ...
