Hydrophilic interaction chromatography (HILIC) was developed by Andrew Alpert for separation of highly polar compounds. HILIC is characterized by a high organic mobile phase concentration and the hydrophilic stationary phase. Thus, the retention times of highly polar compounds are increased with the increase of the hydrophilicity of the solutes. Recently, it became necessary to determine highly...

Interference experiments provide a simple yet powerful tool to unravel fundamental features of quantum physics. Here we engineer an RF-driven, time-dependent bilinear coupling that can be tuned to implement a robust 50:50 beamsplitter between stationary states stored in two superconducting cavities in a three-dimensional architecture. With this, we realize high contrast Hong-OuMandel (HOM) inte...

For general state and action space Markov decision processes, we present sufficient conditions for convergence of both the optimal discounted cost value function and policies to the corresponding objects for the average costs per unit time. We extend Schäl’s [24] assumptions, guaranteeing the existence of a solution to the average cost optimality inequalities for compact action sets, to non-com...

The Watts-Strogatz algorithm of transferring the square lattice to a small world network is modified by introducing preferential rewiring constrained by connectivity demand. The evolution of the network is two-step: sequential preferential rewiring of edges controlled by p and updating the information about changes done. The evolving system self-organizes into stationary states. The topological...

In this paper we deal with two stationary loss queuing network location models. We analyze the influence of filtering policies on the locational aspect of the problems. We assume that requests for service are placed at nodes of a transportation network and they arrive in time as independent homogeneous Poisson processes with different input rates. The considered policies only cover a given prop...

We consider the bandwidth provisioning problem in service overlay networks (SON). We formulate the bandwidth provisioning problem in an optimization framework taking the stochastic processes involved into consideration. First, we provide the optimal solution that maximizes the expected net revenue in a single-link network under stationary traffic demand. Then, we show that the revenue maximizat...

We study a class of continuous time optimal entry-exit decisions under uncertainty for a single firm and for a duopoly. Under very general hypotheses, the optimal policy for a single firm exists and is unique. This unique optimal policy is a barrier policy: A firm optimally enters or exits from an industry when the demand reaches certain barriers. In the context of a duopoly, there may exist mu...

Finding epipoles of a sequence of images has been an important topic of considerable research in the field of computer vision. Epipole is the main feature in epipolar geometry which has enormous demand in computer vision. In most of the cases epipole is estimated from two images and the images are taken by two stationary cameras or by one stationary camera from two different locations. But if t...

We recognize the natural covariant extension for energy-momentum in general relativity: energy-momentum in spacetime as opposed to space. The key indicator is the Tolman energy integral for stationary systems. The demand that the general expression for arbitrary dynamic systems reduce to the Tolman integral in the case of stationary bounded distributions leads to the matter-localized Ricci inte...
