Quantifying and Tracking Flexibility of System Elements to Support (Re)Design Decision‐Making

Systems Engineering, EarlyView.
ABSTRACT Evolving objectives and requirements, risk management processes, and external disruptions frequently drive change in engineered systems. Due to these pressures, system architects must anticipate and manage change throughout a system's lifecycle. Yet, managing change is challenging due to the risk of change propagation.

Weak-lensing Approximation of Wave-optics Effects from General Symmetric Lens Profiles

The Astrophysical Journal
Gravitational lensing of electromagnetic (EM) waves has yielded many profound discoveries across fundamental physics, astronomy, astrophysics, and cosmology. Similar to EM waves, gravitational waves (GWs) can also be lensed.

Exploring Weak Gravitational Lensing Effects by a Regular Black Hole

Spektra: Jurnal Fisika dan Aplikasinya
Gravitational lensing is one of the physical consequences of Einstein’s general theory of relativity, which has been observationally confirmed. This work aims to study the weak gravitational lensing scenario where the lens is a spherically symmetric ...

Late‐Arriving Multilingual Learners' Transition from K–16 Education to the Workforce: Cultural Capital and Habitus Adaptation across Fields

TESOL Quarterly, EarlyView.
Abstract English learners (ELs) in US K–12 schools face systemic barriers that constrain their college and career readiness. Although research has richly documented ELs' limited opportunities to learn in high school and barriers to postsecondary education, much less is known about how late‐arriving ELs move from high school to community college (CC ...

The Gaussian-Drude Lens: A Dusty Plasma Model Applicable to Observations Across the Electromagnetic Spectrum

Universe
When radiation from a background source passes through a cloud of cold plasma, diverging lensing occurs if the source and observer are well-aligned. Unlike gravitational lensing, plasma lensing is dispersive, increasing in strength with wavelength.

What Remains Ours to Think? Reclaiming Critical Thinking in AI‐Augmented Student Leadership Education

New Directions for Student Leadership, EarlyView.
ABSTRACT The arrival of generative artificial intelligence in learning environments has created an urgent question for leadership educators: what remains distinctly ours to think in the act of learning to lead? This article proposes a third orientation beyond the familiar poles of embrace and resistance, centering the reciprocal holding environment as ...

Domain Adaptation in Application to Gravitational Lens Finding

The Astrophysical Journal
The next decade is expected to see a tenfold increase in the number of strong gravitational lenses, driven by new wide-field imaging surveys. To discover these rare objects, efficient automated detection methods need to be developed.

Varying hydraulic strategies within leaves, stems and roots of coexisting desert shrubs

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Effective and continuous root‐to‐leaf hydraulic transport is crucial for plant survival and growth during drought. However, the capacity to resist hydraulic dysfunction remains understudied in leaves and roots, especially for desert shrubs.

Bubbling saddles of the gravitational index

SciPost Physics
We consider the five-dimensional supergravity path integral that computes a supersymmetric index, and uncover a wealth of semiclassical saddles with bubbling topology.
