Spatial and temporal variability in MLT turbulence inferred from in situ and ground-based observations during the WADIS-1 sounding rocket campaign [PDF]

Annales Geophysicae, 2017
In summer 2013 the WADIS-1 sounding rocket campaign was conducted at the Andøya Space Center (ACS) in northern Norway (69° N, 16° E). Among other things, it addressed the question of the variability in mesosphere/lower thermosphere (MLT) turbulence ...

Bolide light curve systematics from 75 recovered meteorites

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2351-2392, September 2026.
Abstract How does the energy deposition profile (light curve), deceleration, and penetration depth in Earth's atmosphere depend on asteroid composition and meteorite type? Here, we present the light curve and velocity profile of 75 bolides from camera‐documented meteorite falls.

Funding diversification for scaling up freshwater restoration in Europe: factors shaping the role of restoration teams

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction Freshwater ecosystem restoration must be rapidly scaled up to address climate change and biodiversity loss, as reflected in the 2024 European Union (EU) Nature Restoration Regulation. Achieving national and international restoration targets is constrained by a persistent funding gap.

LPS from P. gingivalis and Hypoxia Increases Oxidative Stress in Periodontal Ligament Fibroblasts and Contributes to Periodontitis

Mediators of Inflammation, 2014
Oxidative stress is characterized by an accumulation of reactive oxygen species (ROS) and plays a key role in the progression of inflammatory diseases.

Simultaneous in situ measurements of small-scale structures in neutral, plasma, and atomic oxygen densities during the WADIS sounding rocket project [PDF]

Atmospheric Chemistry and Physics, 2019
In this paper we present an overview of measurements conducted during the WADIS-2 rocket campaign. We investigate the effect of small-scale processes like gravity waves and turbulence on the distribution of atomic oxygen and other species in the ...

Saturation Effects in Narrowband Resonance Lidar Measurements, Part 1: Theoretical Consideration of Sodium, Iron, and Helium Lidar Systems

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Atmospheric resonance lidars targeting metallic species in the mesosphere and lower thermosphere have yielded insights into the dynamics of the middle and upper atmosphere for over 50 years. Recently, the technique has been extended to the metastable helium layer, which reaches up to 1,000 km or above.

Hypoxia and P. gingivalis Synergistically Induce HIF-1 and NF-κB Activation in PDL Cells and Periodontal Diseases

Mediators of Inflammation, 2015
Periodontitis is characterized by deep periodontal pockets favoring the proliferation of anaerobic bacteria like Porphyromonas gingivalis (P. gingivalis), a periodontal pathogen frequently observed in patients suffering from periodontal inflammation ...

Saturation Effects in Narrowband Resonance Lidar Measurements, Part 2: Potassium Lidar Systems and Experimental Results

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Resonance lidars targeting the D1 ${D}_{1}$ resonance line of potassium at 770 nm have been employed over the past 5 decades to yield numerous insights into the dynamics of the middle and upper atmosphere. It has long been recognized that these measurements can be severely affected by nonlinear behavior in the scattering process, that is ...

Kant and Baumgarten on positing. Kant's notion of positing as a response to that of Baumgarten

, 2020
In the literature on Kant?s philosophy, it is almost universally ignored that Baumgarten used the notion of positing in a technical sense before Kant. In this article, I try to fill this gap in the literature by providing an analysis of Kant?s notion of ...
