KMT-2022-BLG-1818Lb,c: A Cold Super-Jupiter with a Saturn Sibling

The Astronomical Journal
We present the discovery and analysis of the sixth microlensing two-planet system, KMT-2022-BLG-1818Lb,c, detected by a follow-up program targeting high-magnification events.

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.

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 ...

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.

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 ...

Changing practices, not just rules: Rethinking the institutionalisation of deliberative engagement

Australian Journal of Public Administration, EarlyView.
Abstract When Victoria introduced legislation requiring all 79 councils to adopt deliberative engagement, 92% continued practices the legislation had just removed. This paradox reveals a fundamental challenge in embedding democratic innovations within existing systems of government: legislation signals commitment but cannot disrupt entrenched ...

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.

When Thriving for More Collapses the System: The Academic Reproduction of Uncaring Structures

British Journal of Management, EarlyView.
Abstract This essay argues that the widening gap between aspirational aims and visionary orientations and the prevailing practices in neoliberal academia stems from deeper, historically rooted, market‐based logics shaping our institutions, increasingly governed by economic values and academic subjectivities therein.
