OLFAR - Orbiting low frequency antennas for radio astronomy

open access: yes, 2013
One of the last unexplored frequency ranges in radio astronomy is the frequency band below 30 MHz. New interesting astronomical science drivers for low frequency radio astronomy have emerged, ranging from studies of the astronomical dark ages, the epoch of reionization, exoplanets, to ultra-high energy cosmic rays.

Probing the molecular determinants of emission enhancement in RNA aptamer–metal complex systems

open access: yesPhotochemistry and Photobiology, EarlyView.
Light up aptamer: fluorophore pairs are widely used in sensing and imaging, with coordination complex fluorophores providing specific benefits due to their long‐lived emission. Here, we examined key structural and electronic features of these metal complexes to identify the requirements for productive engagement with an RNA aptamer.

Rethinking Local Choice: Experimental Evidence on Taxpayer Sentiment and Public School Funding

open access: yesPublic Administration Review, EarlyView.
ABSTRACT Taxpayers often have conflicting views on what constitutes fair taxation and how tax revenues should be allocated. We work with Vermont legislators on the policy concern of sentiment in a property tax setting, given the Vermont Supreme Court ruling around the principle of educational equality.

Notation in Early Modern Language Teaching

open access: yesRenaissance Studies, EarlyView.
ABSTRACT This article examines the use of musical notation as a pedagogical tool in early modern language teaching, focusing on Latin, Greek, Hebrew, and briefly, Turkish. While musical notation is typically associated with performance and composition, the sources discussed here demonstrate its broader application as a visual and conceptual system for ...

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

open access: yesExperimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Multiscale mechanistic modelling of heterogeneity in cardiac sub‐cellular calcium handling accounting for variable t‐system density

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Illustration of spatial calcium dynamics (left panels) and the state cycle approximation (middle panel) that enables reduced simulation of spatially dependent dynamics without explicit description of space (right panels). The selected example here illustrates a spontaneous calcium wave, showing temporal snapshots of local calcium
