Analysis of Alternative Metrics for the PAPR Problem in OFDM Transmission
, 2011 The effective PAPR of the transmit signal is the standard metric to capture the effect of nonlinear distortion in OFDM transmission. A common rule of thumb is the log$(N)$ barrier where $N$ is the number of subcarriers which has been theoretically ...

Public Administration Review, Volume 86, Issue 1, Page 143-155, January/February 2026.ABSTRACT Public service delivery has increasingly involved mixed markets, with for‐profit, not‐for‐profit, and government‐delivered programs. In such contexts, regulation can protect the public interest by enhancing safety, expanding consumer choice, or improving the quality of goods or services.

k-Generalized Statistics in Personal Income Distribution
, 2007 Starting from the generalized exponential function $\exp_{\kappa}(x)=(\sqrt{1+\kappa^{2}x^{2}}+\kappa x)^{1/\kappa}$, with $\exp_{0}(x)=\exp(x)$, proposed in Ref. [G. Kaniadakis, Physica A \textbf{296}, 405 (2001)], the survival function $P_{>}(x)=\exp_{\

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM
Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.This research presents a novel hybrid optimization framework combining artificial neural networks (ANN) and particle swarm optimization (PSO) to mitigate the high peak‐to‐average power ratio (PAPR) in asymmetrically clipped optical‐orthogonal frequency division multiplexing (ACO‐OFDM) systems. While conventional PTS effectively reduces PAPR, it suffers

Buildings as Species: Competition and Scaling Rules in Cities
Complexity, Volume 2026, Issue 1, 2026.We look at buildings’ competition over space in cities following the distribution of the perimeters r of the buildings’ circumscribing ellipses. p(r) is shown to follow a power‐law behavior beyond a critical threshold of the density of the built environment.
