Interference-Aware NOMA for Cellular-Connected UAVs: Stochastic Geometry Analysis
IEEE Journal on Selected Areas in Communications, 2021 Efficiency of cellular-connected UAVs is challenged by spectrum inefficiency, limited number of concurrent connectivity, and strong interference. To overcome these issues, in this paper, we study the performance of downlink non-orthogonal multiple access

Discrete stochastic approximations of the Mumford-Shah functional [PDF]
, 2019 We propose a $\Gamma$-convergent discrete approximation of the Mumford-Shah functional. The discrete functionals act on functions defined on stationary stochastic lattices and take into account general finite differences through a non-convex potential ...

Information Geometry of Spatially Periodic Stochastic Systems
Entropy, 2019 We explore the effect of different spatially periodic, deterministic forces on the information geometry of stochastic processes. The three forces considered are f 0 = sin ( π x ) / π and f ± = sin ( π x ) / π

Optimizing Information Freshness in Wireless Networks: A Stochastic Geometry Approach [PDF]
IEEE Transactions on Mobile Computing, 2020 Optimization of information freshness in wireless networks has usually been performed based on queueing analysis that captures only the temporal traffic dynamics associated with the transmitters and receivers.

The stochastic dynamics of nanoscale mechanical oscillators immersed in a viscous fluid [PDF]
, 2004 The stochastic response of nanoscale oscillators of arbitrary geometry immersed in a viscous fluid is studied. Using the fluctuation-dissipation theorem it is shown that deterministic calculations of the governing fluid and solid equations can be used in

Dimensioning of 5G Networks by Using Stochastic Geometry
International Journal of Information and Communication Technology Research, 2021 In this paper, we propose an analytical model for dimensioning of Orthogonal Frequency Division Multiple Access (OFDMA) systems in 5G networks by considering Internet of Thing (IoT) application using stochastic geometry.

Semi-Grant-Free NOMA: A Stochastic Geometry Model [PDF]
IEEE Transactions on Wireless Communications, 2020 Grant-free (GF) transmission holds promise in terms of low latency communication by directly transmitting messages without waiting for any permissions. However, collision situations may frequently happen when limited spectrum is occupied by numerous GF ...

Stochastic quantization on Lorentzian manifolds
Journal of High Energy Physics, 2021 We embed Nelson’s theory of stochastic quantization in the Schwartz-Meyer second order geometry framework. The result is a non-perturbative theory of quantum mechanics on (pseudo-)Riemannian manifolds.

A Stochastic Geometry Approach to Doppler Characterization in a LEO Satellite Network [PDF]
ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020 A Non-terrestrial Network (NTN) comprising Low Earth Orbit (LEO) satellites can enable connectivity to underserved areas, thus complementing existing telecom networks. The high-speed satellite motion poses several challenges at the physical layer such as

Geometric thermodynamics for the Fokker–Planck equation: stochastic thermodynamic links between information geometry and optimal transport [PDF]
Information Geometry, 2022 We propose a geometric theory of non-equilibrium thermodynamics, namely geometric thermodynamics, using our recent developments of differential-geometric aspects of entropy production rate in non-equilibrium thermodynamics.
