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

International 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 ...

Capacity and limitations of US wild meat donation programmes

People and Nature, EarlyView.
Abstract Historically, sharing of wild harvests to facilitate food security followed concepts of kin selection and reciprocal altruism. However, cultural shifts have reduced access to foods for some populations in modern times. Cultural altruism through sustainably harvested wild meat donation programmes (WDPs) can reduce food and nutritional ...

Social cohesion in restoration landscapes: The case of Rwanda

People and Nature, EarlyView.
Abstract Ecosystem restoration is recognized as a strategy for addressing landscape degradation. In contexts where ecological degradation overlaps with the deterioration of social cohesion, restoration must also contribute to rebuilding social ties alongside restoring ecosystems.

Some bounds for skewed α-Jensen-Shannon divergence

Results in Applied Mathematics, 2019
Based on the skewed Kullback-Leibler divergence introduced in the natural language processing, we derive the upper and lower bounds on the skewed version of the Jensen-Shannon divergence and investigate properties of them.

Exact Robust Filtering and Differentiation Based on Sliding Modes and Homogeneity

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This article addresses the problem of online estimation of the derivatives of a signal corrupted by measurement noise. The measured signal is modeled as the sum of a smooth nominal component and a uniformly bounded noise term. A key objective is to attenuate the effect of high‐frequency noise.

Integrating Sustainability Through Socio‐Scientific Issues in Chile: Towards a Decolonial Chemistry Education

Science Education, EarlyView.
ABSTRACT This study examines how integrating sustainability through socio‐scientific issue (SSI) in secondary chemistry teaching shapes epistemic openness and closure from a decolonial perspective, as mediated through classroom discourse. Drawing on a co‐planned lesson on copper mining in Chile – a scientifically rich yet ethically and politically ...

Financial Inclusion for Smallholders: Integrating a Resource Nexus Approach Into Agricultural Finance Systems

Sustainable Development, EarlyView.
ABSTRACT Smallholder farmers remain structurally excluded from the current agricultural finance system. Existing research in this area examines financial inclusion through fragmented environmental, social, and economic lenses, limiting system‐level understanding.

Some generalizations of Mercer inequality and its operator extensions

Miskolc Mathematical Notes
We give a more general form of the Mercer inequality by replacing some constants by positive operators. As some consequences, our results produce a Jensen operator inequality for superquadratic functions.

Institutional Determinants of Environmental Disclosure for Sustainable Development: The Moderating Role of Gender‐Diverse Boards

Sustainable Development, EarlyView.
ABSTRACT This study examines the institutional determinants of environmental disclosure in the context of sustainable development and analyses the moderating role of board gender diversity in this relationship. Using an international sample of 26 countries over the period 2014–2023, we explore how macro‐level socioeconomic, cultural, political, and ...

What Does It Take? A Cross‐National Study Exploring Drivers for Willingness to Engage in Effortful Climate Action

Sustainable Development, EarlyView.
ABSTRACT While much is known about what drives general participation in climate action, less is known about the drivers of actions that are explicitly linked to time, resource, or convenience constraints (i.e., effortful climate action). Understanding what drives effortful climate action is important to effectively tackle climate change, as many high ...
