Landslide preparation by forestry activity in a region of high erosion rates: Waingake Landslide, northeast New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 1015-1030, December 2025.
ABSTRACT Northeastern New Zealand’s sedimentary rocks and soils are particularly vulnerable to landsliding, with some of the highest specific sediment yields, globally. In addition to earthquakes, rainfall is considered an important landslide triggering process.

The Impacts of Bars, Spirals, and Bulge Size on Gas-phase Metallicity Gradients in MaNGA Galaxies

The Astrophysical Journal
As galaxies evolve over time, the orbits of their constituent stars are expected to change in size and shape, moving stars away from their birth radius. Radial gas flows are also expected. Spiral arms and bars in galaxies are predicted to help drive this

Molecular Gas Kinematics in Barred Spiral Galaxies [PDF]

The Astrophysical Journal, 1999
To quantify the effect that bar driven mass inflow can have on the evolution of a galaxy requires an understanding of the dynamics of the inflowing gas. In this paper we study the kinematics of the dense molecular gas in a set of seven barred spiral galaxies to determine which dynamical effects dominate.

Groundwater Microbial Diversity Associated With Icelandic Basaltic Subsurface Environments

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Overview of microbial diversity and environmental drivers in Icelandic deep basaltic aquifers. Using 16S rRNA gene metabarcoding across 22 geothermal wells spanning broad temperature, pH, and bedrock‐age gradients, the study reveals distinct bacterial and archaeal community structures shaped by temperature, pH, and host‐rock reactivity.

Gas Dynamics in the Barred Seyfert Galaxy NGC4151 - II. High Resolution HI Study

, 1998
We present sensitive, high angular resolution (6" x 5") 21-cm observations of the neutral hydrogen in the nearby barred Seyfert galaxy, NGC4151. These HI observations, obtained using the VLA in B-configuration, are the highest resolution to date of this ...

Stellar Bars in Isolated Gas-rich Spiral Galaxies Do Not Slow Down

The Astrophysical Journal, 2023
Elongated bar-like features are ubiquitous in galaxies, occurring at the centers of approximately two-thirds of spiral disks in the nearby Universe. Due to gravitational interactions between the bar and the other components of galaxies, it is expected ...

In silico, in vitro and ex vivo characterization of cystic fibrosis transmembrane conductance regulator pathogenic variants localized in the fourth intracellular loop and their rescue by modulators

British Journal of Pharmacology, Volume 182, Issue 24, Page 6063-6080, December 2025.
Background and Purpose Cystic fibrosis (CF) is due to loss‐of‐function variants of the CF transmembrane conductance regulator (CFTR) channel. The most effective treatment for people with CF carrying the F508del mutation is the triple combination of elexacaftor–tezacaftor–ivacaftor (ETI).

Bars do drive spiral density waves

, 2010
Recently, Buta etal. (2009) examined the question "Do Bars Drive Spiral Density Waves?", an idea supported by theoretical studies and also from a preliminary observational analysis Block etal (2004).

A hitchhiker's guide to modern, practical cyanobacterial taxonomy

Journal of Phycology, Volume 61, Issue 6, Page 1536-1552, December 2025.
Abstract There has been an explosion of new Cyanobacterial taxa described within the last two decades. Cyanobacteria exhibit incredible ecological versatility and morphological variability, and thousands of species have already been described using “traditional” approaches (e.g., morphological features).
