Ionospheric Ambipolar Electric Fields of Mars and Venus: Comparisons Between Theoretical Predictions and Direct Observations of the Electric Potential Drop

open access: yesGeophysical Research Letters, 2019
We test the hypothesis that their dominant driver of a planetary ambipolar electric field is the ionospheric electron pressure gradient (∇Pe). The ionospheres of Venus and Mars are mapped using Langmuir probe measurements from NASA's Pioneer Venus ...

Organic Transistor‐Based Neuromorphic Electronics and Their Recent Applications

open access: yesSmall Methods, EarlyView.
This review highlights recent progress in organic neuromorphic electronics, showing how organic semiconductors enable synaptic and neuronal functions with low power, mechanical flexibility, and biocompatibility. By bridging materials, devices, and systems, organic platforms are accelerating brain‐inspired computing toward applications in artificial ...

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Approaches for Retrieving Sulfur Species Abundances from Dual X–Ka-band Radio Occultations of Venus with EnVision and VERITAS

open access: yesThe Planetary Science Journal, 2023
The EnVision and VERITAS missions to Venus will fly with X- and Ka- band telecommunications channels, which can be used to conduct radio occultation studies of Venus’ atmosphere.

Visual Satire Under German Censorship: The Card Game Pharo in Johann Heinrich Ramberg's Illustrations and in Contemporary Descriptions

open access: yesJournal for Eighteenth-Century Studies, EarlyView.
Abstract This article examines image–text relations in German illustrations of gambling around 1800, specifically focusing on the card game Pharo and the artist Johann Heinrich Ramberg. It shows Ramberg's technique of reuse and variation as well as the degree of satire in the designs and their accompanying descriptive or fictional texts.

Weak, Quiet Magnetic Fields Seen in the Venus Atmosphere. [PDF]

open access: yes, 2016
The existence of a strong internal magnetic field allows probing of the interior through both long term changes of and short period fluctuations in that magnetic field. Venus, while Earth's twin in many ways, lacks such a strong intrinsic magnetic field,

How Can Accountants Enhance (or Save) Natural and Cultural Capital Valuation? Engaging Academics: A Collaboration with CPA Canada and the Canadian Commission for UNESCO*

open access: yesAccounting Perspectives, Volume 24, Issue 1, Page 21-46, March 2025.
ABSTRACT Accountants should engage more with natural and cultural capital accounting to make tools more accessible and to ensure critical information is provided to decision‐makers. While ecological economists have continued to innovate and design tools, corporate‐level accounting has seemingly lagged behind.

Mountain Waves in the Upper Atmosphere of Venus

open access: yesGeophysical Research Letters
Planetary‐scale mountain waves have been observed at the cloud top of Venus and throughout the cloud deck. As they propagate from the surface to the cloud layers, multiple observations and numerical simulations have shown that they grow in size and do ...

An uppermost haze layer above 100 km found over Venus by the SOIR instrument onboard Venus Express

open access: yesEarth, Planets and Space, 2019
The Solar Occultation in the InfraRed (SOIR) instrument onboard Venus Express was designed to measure the Venusian atmospheric transmission at high altitudes (65–220 km) in the infrared range (2.2–4.3 μm) with a high spectral resolution. In this work, we

Transcriptomic prey‐capture responses in convergently evolved carnivorous pitcher plants

open access: yesNew Phytologist, EarlyView.
Summary The Australian pitcher plant Cephalotus and the Asian pitcher plant Nepenthes exhibit striking morphological and functional similarities, serving as compelling examples of convergent evolution. Although trapping pitchers in both lineages represent some of the most elaborate leaf structures in angiosperms, it remains unknown whether their ...
