Constructed Response Paragraph Jigsaw Puzzle Test for Measuring Structure Building Ability
Applied Cognitive Psychology, Volume 40, Issue 1, January/February 2026.ABSTRACT This study examined whether paragraph jigsaw puzzle (PJP) test can be used to measure structure building ability, the ability to construct cohesive mental representations. We developed a constructed‐response version of the PJP test and scored it with a string‐similarity algorithm that allows for partial credit.

A Thermal Origin to the Asymmetry of the Permanent Dust Cloud at the Moon
Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract The Moon's surface, lacking an atmosphere, is continually bombarded by high‐speed micro‐meteoroids, creating a highly porous regolith composed of very fine grains. This regolith's porosity decreases with depth due to compression. Besides creating vapor and melt, micro‐meteoroid impacts eject lunar dust, redistributing regolith grains, which ...

The Chemical Record, Volume 25, Issue 7, July 2025.The radical Pietist Johann Conrad Dippel was a self‐proclaimed adept – a maker of gold and the philosophers’ stone. He was also a magister of theology, a doctor of medicine, and a self‐taught chemist, who coinvented the pigment Prussian Blue together with Johann von Diesbach, became known for his animal pyrolysis oil, his wonder‐wound balm, his ...

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.Abstract We analyze five large‐scale tail disturbances in comet C/2022 E3 (ZTF)'s ion tail using images from astrophotographers, tracking specific features within the tail to determine their speeds. We employ a heliosphere model to estimate when the comet crossed the heliospheric current sheet (HCS).

Helium in Mercury's Extended Exosphere Determined by Pick‐Up Generated Ion Cyclotron Waves
Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.Abstract Helium (He) was first detected by remote spectroscopic observations of the Ultraviolet Visible Spectrometers (UVVS) instrument in Mercury's exosphere during the three Mariner 10 flybys in 1974 and 1975. Here, we derive the first in situ radial density profile of He in Mercury's extended exosphere by analyzing magnetic field and plasma ...

Occultation of compact radio sources by the ion tail of Halley's Comet [PDF]
, 1987 Enhancements of scintillations of the compact radio sources PKS 2314+03 and 1827-360 were observed at 103 MHz and 408 MHz during 18-21 December 1985 and on 29 March 1986, respectively, when the plasma tail of Halley's Comet swept across them.

Ion‐Scale Characteristics of the Martian Magnetic Pile‐Up Boundary Layer
Geophysical Research Letters, Volume 52, Issue 3, 16 February 2025.Abstract The Martian magnetic pile‐up boundary (MPB) delineates the interface between the magnetosheath and the induced magnetosphere, but its global ion‐scale characteristics remaining unclear. Utilizing a three‐dimensional Hall magnetohydrodynamic (MHD) model, this study aims to reveal the features of the MPB layer, including magnetic field, current ...
