Optimization of Gradient Pulse Shape Prediction Using Temporal Convolutional Networks

Magnetic Resonance in Medicine, EarlyView.
Purpose To improve TCN‐based gradient‐waveform prediction with respect to acquisition efficiency and inference speed, and to evaluate its use for radial imaging. Methods Gradient waveforms were measured using a thin‐slice method on a preclinical MRI system. Separate TCN models were trained for each physical gradient axis to predict both gradient and B0$

Reliability Analysis of an Autonomous Underwater Vehicle Using Fault Tree

, 2013
Autonomous underwater vehicle (AUV) is an automatic machine working autonomously without human intervention in underwater environment. It contains hundreds of components. Each component may fail unpredictably or even cause the AUV not to work.

Weakly Convex Ridge Regularization for 3D Non‐Cartesian MRI Reconstruction

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose While highly accelerated non‐Cartesian acquisition protocols significantly reduce scan time, they often entail long reconstruction delays for 3D data. Deep learning–based reconstruction methods can alleviate this, but typically rely on complex, highly parametrized architectures.

Non‐Invasive Triage of Bladder Outlet Obstruction and Detrusor Underactivity in Men With Lower Urinary Tract Symptoms: A Narrative Review and Conceptual Framework for Depth‐Aware Multimodal Transcutaneous Testing

Neurourology and Urodynamics, EarlyView.
ABSTRACT Introduction Differentiating bladder outlet obstruction (BOO) from detrusor underactivity (DU) remains a major unmet need in the management of lower urinary tract symptoms in men. Although pressure–flow urodynamics provide a definitive physiological classification, their invasiveness limits their widespread use.

Warming and predation drive rapid evolution of ecosystem functioning but not functional traits

Oikos, EarlyView.
Global environmental change can rapidly reshape phenotypic trait distributions through adaptive and neutral processes. Yet, disentangling their relative contributions remains a major challenge, particularly for traits underpinning ecosystem functioning.

Shaping biodiversity from within: How experts' perceptions of values, rules and knowledges influence biodiversity assessment

People and Nature, EarlyView.
Abstract While biodiversity conservation has had its local success, worldwide biodiversity loss continues rapidly. Despite the push towards more inclusive and equitable approaches, conservation practices often reinforce existing conceptualizations of biodiversity, excluding other ways of knowing and valuing nature.

Planting for healthy air: Urban biodiversity enhances natural chemical environments

PLANTS, PEOPLE, PLANET, EarlyView.
Cities urgently need nature to improve public health, support biodiversity, and increase resilience to climate change. Yet not all green spaces offer the same benefits. In this study, we show that more diverse urban plantings create richer “chemical environments”; subtle, naturally scented atmospheres formed by plant emissions that can influence how ...

Increased utilitarian value of invasive species in regions with long invasion history may limit public engagement for invasion control

PLANTS, PEOPLE, PLANET, EarlyView.
Positive perceptions of invasive species can hinder effective management, especially if management efforts that are rooted in scientific theories are misaligned with local ecological knowledge. We documented local ecological knowledge about land invasibility as predicted by invasion biology theories. Participants with greater local ecological knowledge

Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Needle in a haystack: Holocene history of European larch in Central Europe revisited

PLANTS, PEOPLE, PLANET, EarlyView.
Defining nativity of species is crucial for their management. However, this is a complex task, especially for species that have been used and spread by humans for a long time. We combined paleoecological records with extensive genetic data to investigate the Holocene history of European larch—a common and economically important tree species in Central ...
