Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

Responsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

Big Bird: A global dataset of birds in drone imagery annotated to species level

Remote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

High‐Speed Rail and Spatial Equity: Unpacking the Sustainability Paradox of Land Use and Fiscal Pressure in County‐Level Cities

Sustainable Development, EarlyView.
ABSTRACT Infrastructure‐led development in rapidly urbanizing economies often generates accessibility gains that fail to translate into balanced urban outcomes, particularly when local fiscal institutions redirect those gains toward revenue‐generating land uses. Filling this gap, especially in fiscally constrained county‐level cities where land finance

Bridging Efficiency Gaps in Rice Production: A Primal System Analysis of Technical and Allocative Constraints in Bangladesh

Sustainable Development, EarlyView.
ABSTRACT Declining natural resources, rising production costs, and diminishing returns from input‐intensive practices threaten the sustainability of smallholder rice systems in Bangladesh. Using a primal system approach and survey data from 1869 rice‐producing households, this study evaluates technical and allocative inefficiency across major agro ...

Two hearts that beat as one: Signals, narratives, and financing (less) novel ventures via equity crowdfunding

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Financial resource acquisition is crucial for ventures but hindered by uncertainty. While signaling mitigates this uncertainty, its effectiveness hinges on venture novelty and the narratives used to clarify embedded information. Adopting a configurational lens, we examine the interplay among novelty, signals, and narratives in
