Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

People and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Achieving Carbon Neutrality Through Green Supply Chain Management, Eco‐Innovation, and Green Energy: The Moderating Effect of Green Finance

Sustainable Development, EarlyView.
ABSTRACT The pursuit of Sustainable Development Goals (SDGs) 7, 9, 12, and 13, centered on affordable clean energy, industrial innovation, responsible production, and climate action, has gained momentum across Latin American economies. However, the region continues to face the dual challenge of achieving economic growth while mitigating rising carbon ...

Temporalities of Trauma: An Exploration of the Role of Socio‐Temporal Rhythms in Foster Carer Experiences of Vicarious Trauma

Child &Family Social Work, EarlyView.
ABSTRACT Foster carers raise children whose trauma backgrounds likely result in behaviours that are not simply challenging, but which can also result in vicarious trauma for foster carers. While a growing body of research has explored vicarious trauma among foster carers, to date research has not explored how temporal shifts produced by raising foster ...

See4D: Pose‐Free 4D Generation via Auto‐Regressive Video Inpainting

Computer Graphics Forum, EarlyView.
Abstract Immersive applications call for synthesizing spatiotemporal 4D content from casual videos without costly 3D supervision. Existing video‐to‐4D methods typically rely on manually annotated camera poses, which are labor‐intensive and brittle for in‐the‐wild footage.
