Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

Absolutely flat algebras in tensor categories

open access: yes
In this talk I will discuss the connection between (semi)simplicity and absolute flatness of (ind)algebras in tensor categories. I will present some open problems, their motivation and history, relating to a question by Deligne, a conjecture by Etingof ...

Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Supply chain disruptions can lead to both tactical (i.e., loss of short‐term sales during a disruption) and strategic (i.e., loss of long‐term market share) consequences. We model the impact of a supply disruption on competing supply chains in which two firms compete for a limited backup supply.

Nonprofit Governance and Financial Stability: A Study of Government‐Funded Social Services

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT Nonprofit social service providers are essential in delivering vital services, often with public funding. This study adopts a contingency perspective to explore the relationship between organizational governance and financial stability in publicly funded nonprofit organizations. We use a combination of comparative multilevel analysis (CMA) and

Coverage‐based rarefaction fails to quantify relative species richness

open access: yesOikos, EarlyView.
Coverage‐based rarefaction (CBR) is a high‐profile tool for assessing biodiversity that provides relative species richness estimates by leveraging the Good‐Turing index u to interpolate. In contrast to alternatives such as the Shannon and Simpson indices, CBR's main appeal is providing values in units of species. CBR is tested against a series of other
