Design and Development of a Modular Ballistic Pendulum for High‐Impulse Measurement in Contact and Near‐Field Explosive Loading

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...

Hexapod Locomotion Across Structured and Unstructured Terrains: A Data‐Driven Review of Modeling, Control, and Validation

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.

Recognized and Realigned: A Veteran Teacher's Moves to Leverage Familiar Forms of Epistemic Agency While Using Next Generation Science Standard Inspired Materials

open access: yesScience Education, EarlyView.
ABSTRACT For 3 days, Amy, a veteran middle school science teacher, struggled to engage students in using Next Generation Science Standards (NGSS)‐aligned curriculum designed to facilitate scientific argumentation. Amy consistently used productive framing bids or cues to redirect students from “doing school” toward sensemaking and “doing science ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

open access: yesSustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Beyond the Checklist: Meta‐Indicators for Evaluating Effectiveness of Neighbourhood Sustainability Assessment Tools

open access: yesSustainable Development, EarlyView.
ABSTRACT Neighbourhood Sustainability Assessment Tools (NSATs) are widely used to support sustainable urban planning, development assessment and neighbourhood‐scale decision‐making. However, existing tools continue to exhibit persistent limitations, including uneven coverage of sustainability dimensions, limited governance integration, weak stakeholder
