On Our Cosmic (In)significance

open access: yesRatio, EarlyView.
ABSTRACT This article discusses three interpretations of cosmic significance, all of which reveal something important about the notion of significance. Along the way, it proposes a unified view of significance by combining elements of each of the views.

Predictions for Sparse Photometry of Jupiter-family Comet Nuclei in the LSST Era

open access: yesThe Planetary Science Journal
The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory will deliver high-quality, temporally sparse observations of millions of solar system objects on an unprecedented scale.

The demographics of long-period comets

open access: yes, 2015
The absolute magnitude and perihelion distributions of long-period comets are derived, using data from the Lincoln Near-Earth Asteroid Research (LINEAR) survey. The results are surprising in three ways.

Linear Viscoelastic Behavior of n‐Alkane Diluted Polyethylene Melts: Sorption, Desorption, and Oscillatory Rheometry

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 39, October 15, 2026.
This study systematically maps polyolefin dilution dynamics using a homologous series of n‐alkanes. Integrating gravimetric sorption, subsequent controlled desorption, and oscillatory rheometry establishes a precise framework to analyze reduction in viscosity at least for polymer diluent mixtures with polymer concentration > 35% and diluent ...

Dust Production Rates in Jupiter-family Comets. II. Trends and Population Insights from ATLAS Photometry of 116 JFCs

open access: yesThe Planetary Science Journal
Jupiter-family comets (JFCs) have orbital periods of less than 20 yr and therefore undergo more frequent sublimation compared to other comet populations.

Investigation of Split Comet 240P/NEAT

open access: yesThe Astronomical Journal
We present time-series observations of the split comet 240P/NEAT near perihelion, obtained using the Nordic Optical Telescope. The brighter component, 240P-A, has an estimated radius in the range 400–600 m, and loses dust at the peak rate 130 kg s ^−1 ...

A Search of Reactivated Comets [PDF]

open access: yes, 2017
Dormant or near-dormant short-period comets can unexpectedly regain the ability to eject dust. In many known cases, the resurrection is short-lived and lasts less than one orbit.

Evaluating the Impact of Clonidine and Midazolam Premedication on Emergence Delirium in Pediatric Patients

open access: yesPediatric Anesthesia, Volume 36, Issue 10, Page 1290-1307, October 2026.
ABSTRACT Background Preoperative anxiety is common in children and is associated with emergence delirium—a distressing postoperative complication characterized by agitation and disorientation. Midazolam has long been the drug of choice for preoperative anxiolysis.
