Lossy State Communication over Fading Multiple Access Channels

open access: yesEntropy, 2023
Joint communications and sensing functionalities integrated into the same communication network have become increasingly relevant due to the large bandwidth requirements of next-generation wireless communication systems and the impending spectral ...

A Quantized Johnson Lindenstrauss Lemma: The Finding of Buffon's Needle [PDF]

open access: yes, 2015
In 1733, Georges-Louis Leclerc, Comte de Buffon in France, set the ground of geometric probability theory by defining an enlightening problem: What is the probability that a needle thrown randomly on a ground made of equispaced parallel strips lies on ...

Spectral Properties of Clipping Noise

open access: yesMathematics, 2021
One serious disadvantage of any multicarrier-modulation technique such as orthogonal frequency division multiplexing (OFDM) is its high peak-to-average-power ratio (PAPR) which might lead to signal clipping in several scenarios.

Nuts and Bolts of a Realistic Stochastic Geometric Analysis of mmWave HetNets: Hardware Impairments and Channel Aging [PDF]

open access: yes, 2019
© 2019 IEEE.Motivated by heterogeneous network (HetNet) design in improving coverage and by millimeter-wave (mmWave) transmission offering an abundance of extra spectrum, we present a general analytical framework shedding light on the downlink of ...

Thermo-mechanical analyses for optimized path planning in laser aided additive manufacturing processes

open access: yesMaterials & Design, 2019
Laser deposition strategies can have significant effect on the temperature distribution for multi-bead multi-layered additive manufacturing. Its influence on thermal field will affect the induced residual stress and distortion.

Zero-Delay Joint Source-Channel Coding in the Presence of Interference Known at the Encoder [PDF]

open access: yes, 2016
Zero-delay transmission of a Gaussian source over an additive white Gaussian noise (AWGN) channel is considered in the presence of an additive Gaussian interference signal.

Optimal Insurance for a Minimal Expected Retention: The Case of an Ambiguity-Seeking Insurer

open access: yesRisks, 2016
In the classical expected utility framework, a problem of optimal insurance design with a premium constraint is equivalent to a problem of optimal insurance design with a minimum expected retention constraint.

Multifractal analysis of the irregular set for almost-additive sequences via large deviations [PDF]

open access: yes, 2015
In this paper we introduce a notion of free energy and large deviations rate function for asymptotically additive sequences of potentials via an approximation method by families of continuous potentials.

Guarantees on learning depth-2 neural networks under a data-poisoning attack

open access: yes, 2020
In recent times many state-of-the-art machine learning models have been shown to be fragile to adversarial attacks. In this work we attempt to build our theoretical understanding of adversarially robust learning with neural nets.

Additive scales in degenerative disease - calculation of effect sizes and clinical judgment

open access: yesBMC Medical Research Methodology, 2011
Background The therapeutic efficacy of an intervention is often assessed in clinical trials by scales measuring multiple diverse activities that are added to produce a cumulative global score.
