Learning as Compost: Reorienting Evaluation in an Era of Authoritarian Drift

New Directions for Evaluation, EarlyView.
ABSTRACT We synthesize insights from seven cases to interrogate a central assumption of the learning function of evaluation: Learning can be strengthened through better design, integration, or alignment with accountability systems. Taking the issue's conceptual framework seriously, the essay reflects what the cases reveal about the nature of learning ...

Bio‐inspired vision: From principle, material architectures to system‐level integration

FlexMat, EarlyView.
This review introduces the development and mechanism of electronic and ionic bio‐inspired vision devices respectively. Then, it explores the impact of structure on bio‐inspired visual performance from the scale of intrinsic materials and device. Finally, it concludes that only by combining advanced software and technology can more complex vision ...

Lie triple systems and warped products.

Rendiconti di Matematica e delle Sue Applicazioni, 2001
Let \((M = B \times F, g_{\omega} = g_B + \omega^2 g_F)\) be a warped product, with \(\omega: B \to \mathbb R^+\) a function, \(g_B\) a Riemannian metric on the manifold \(B\) and \(g_F\) a Riemannian metric on the manifold \(F\). In the present paper the authors study the conditions ensuring that \((M, g_{\omega})\) is locally symmetric. Let \(\Omega\)

Magneto‐responsive fibers and fabrics for soft systems

FlexMat, EarlyView.
Abstract The combination of functional materials in fiber form has led to a surge in the integration of functional fibers and fabrics into soft systems that span sensing, communication, and actuation domains. A key subset is magnetic fibers and fabrics.

Warped area-minimizing hypersurface and warped product metric

By studying the warped(or weighted) area-minimizing hypersurface, we prove that the metric can be locally split as a warped product metric under the spectral Ricci or spectral scalar curvature lower bound condition.

Improved Post‐Processing Framework for Whole Slide Imaging and 3D Reconstruction

Microscopy Research and Technique, EarlyView.
Workflow for 3D reconstruction of marmoset whole‐slide histology. Individual tiles undergo vignette correction to address illumination artifacts before stitching into full‐section images. Sections are then reconstructed using the Possum framework, with a level‐set method incorporated at the nonlinear deformable stage to stabilize alignment and reduce ...

Diffusion MRI of the Body: Beyond PGSE‐EPI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Diffusion magnetic resonance imaging (dMRI) is a widely used clinical imaging technique which is sensitive to changes in tissue microstructure including cellularity, perfusion, and tissue damage. DMRI has been used in whole‐body imaging as well as in targeted imaging of every major anatomical region.

Amyloid‐β–Related Cortical Susceptibility Alterations in Individuals Under Assessment for Alzheimer's Disease: A χ‐Separation Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Assessment of amyloid‐β (Aβ) burden and associated iron deposition and neurodegeneration is important for Alzheimer's disease (AD) management. Although quantitative susceptibility mapping (QSM) detects iron and myelin changes, conventional metrics suffer from signal cancelation between paramagnetic and diamagnetic components ...
