Alignments between Galaxies and the Cosmic Web at z ∼ 1–2 in the IllustrisTNG Simulations

The Astrophysical Journal, 2023
Galaxy formation theories predict that galaxy shapes and angular momenta have nonrandom alignments with the cosmic web. This leads to so-called intrinsic alignment between pairs of galaxies, which is important to quantify as a nuisance parameter for weak

A Physically Motivated Framework to Compare Pair Fractions of Isolated Low- and High-mass Galaxies across Cosmic Time

The Astrophysical Journal
Low-mass galaxy pair fractions are understudied, and it is unclear whether low-mass pair fractions evolve in the same way as more massive systems over cosmic time. In the era of JWST, Roman, and Rubin, selecting galaxy pairs in a self-consistent way will

Liquid biopsy across cancers: Integrating circulating biomarkers, tumor biology, artificial intelligence, and clinical translation

Interdisciplinary Medicine, EarlyView.
Liquid biopsy uses non‐invasive sampling of blood or body fluids to isolate circulating analytes, including circulating tumor DNA, circulating tumor cells, extracellular vesicles, and RNA. These are analyzed using next‐generation sequencing, qPCR, and proteomics to inform cancer detection, monitoring, and characterization. Figure created with BioRender.

Probing Dark Matter Halos of High-redshift Quasars via Wide-field Clustering

The Astrophysical Journal Letters
High-redshift quasars are powerful tracers of both astrophysical processes and large-scale structure in the early Universe. Using a sample of 1242 spectroscopically confirmed quasars and 827 highly reliable photometric quasar candidates selected with a ...

HD‐DRUM Rhythmic Training in Huntington's Disease: Feasibility, Motor, and Brain Microstructural Pilot Signals

Movement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Rhythmic cuing may benefit motor functions in Huntington's disease (HD) by compensating for the loss of predictive timing associated with basal ganglia degeneration. To our knowledge no remote rhythmic training application has been developed or evaluated that seeks to improve function in HD.

How ventures maintain stakeholder support amidst operational legitimacy threats

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary We explore how ventures mitigate operational legitimacy threats—threats that originate within the venture and challenge claims relating to the venture's ability to deliver on its promised value proposition. Through an inductive study of four ventures working to deliver their promised products following successful crowdfunding ...
