“It Is Much Safer to Be Sparse than Connected”: Safe Control of Robotic Swarm Density Dynamics with PDE Optimization with State Constraints

Advanced Intelligent Systems, EarlyView.
This paper proposes a novel control framework to ensure safety of a robotic swarm. A feedback optimization controller is capable of driving the swarm toward a target density while keeping risk‐zone exposure below a safety threshold. Theory and experiments show how safety is more effectively achieved for sparsely connected swarms.

Fibonacci-Ishikawa iterative method in modular spaces for asymptotically non-expansive monotonic mathematical operators

Journal of Inequalities and Applications
In the context of modular function spaces, we propose and investigate the Fibonacci-Ishikawa iteration method applied to non-expansive, asymptotically monotonic mathematical operators.

Almost Everywhere Convergence of Orthogonal Series Revisited

Journal of Mathematical Analysis and Applications, 1994
We deal with single and double orthogonal series and give sufficient conditions which ensure their convergence almost everywhere. Among others, we prove that if \[ \sum^ \infty_{j= 3} \sum^ \infty_{k= 3} a_{jk}^ 2\log j\log k\log^ 2_ +(1/a^ 2_{jk})

Racism at Work: A Critical Qualitative Investigation

The Career Development Quarterly, EarlyView.
ABSTRACT An area of life that is profoundly impacted by anti‐Black racism is the world of work. Black Americans face persistent barriers from hiring to wage inequality to everyday mistreatment. In response, we conducted a critical qualitative investigation to explore how racism manifests in workplaces, uncover overlooked aspects of Black Americans ...

Convergence Almost Everywhere and Divergence Everywhere of Taylor and Dirichlet Series

Real Analysis Exchange, 2004
Nine theorems are proved. The following ones are typical. Theorem 3.2. There exists a Dirichlet series \[ f(x):= \sum^\infty_{n=1} a_n n^{-s} \] with convergence and boundedness in the half-plane \(\mathbb{C}_0:=\{s\in\mathbb{C}:\text{Re}(s)> 0\}\), and such that \(\sum a_n n^{it}\) diverges for each \(t\in\mathbb{R}\). Theorem 5.3. Let \((a_n\geq 1)\)

The Future of Foundation Machine Learning Potentials and DFT in Homogeneous Catalysis: Competition or Synergy?

Chemistry – A European Journal, EarlyView.
Machine‐learning potentials are increasingly taking on the exploratory tasks of homogeneous catalysis, enabling rapid conformer sampling and reaction‐space mapping. However, when selectivity depends on subtle electronic effects, electronic‐structure methods remain essential.

Bayesian inverse ensemble forecasting for COVID‐19

Canadian Journal of Statistics, EarlyView.
Abstract Variations in strains of COVID‐19 have a significant impact on the rate of surges and on the accuracy of forecasts of the epidemic dynamics. The primary goal for this article is to quantify the effects of varying strains of COVID‐19 on ensemble forecasts of individual “surges.” By modelling the disease dynamics with an SIR model, we solve the ...

Nonsmooth spectral gradient methods for unconstrained optimization

EURO Journal on Computational Optimization, 2017
To solve nonsmooth unconstrained minimization problems, we combine the spectral choice of step length with two well-established subdifferential-type schemes: the gradient sampling method and the simplex gradient method.

On almost-everywhere convergence of inverse spherical transforms [PDF]

Pacific Journal of Mathematics, 1995
Suppose that \(G\) is a noncompact, connected, semisimple Lie group with finite center and real rank one, and with a maximal compact subgroup \(K\). We assume that an Iwasawa decomposition \(G=ANK\) is fixed. Let \({\mathcal A}\) denote the Lie algebra of \(A\), so that \({\mathcal A}\) is isomorphic to the real line.

A goodness‐of‐fit test for regression models with discrete outcomes

Canadian Journal of Statistics, EarlyView.
Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.
