On the Spiral Structure of the Milky Way Galaxy

, 2010
We consider the possible pattern of the overall spiral structure of the Galaxy, using data on the distribution of neutral (atomic), molecular, and ionized hydrogen, on the base of the hypothesis of the spiral structure being symmetric, i.e.

Review of Analytical Lithium Detection and Quantification Methods Along the Lithium Value Chain

Applied Research, Volume 4, Issue 6, December 2025.
This article reviews a selection of suitable state‐of‐the‐art analytical methods for different scales of spatial resolution and detection of lithium for a variety of lithium‐bearing materials along the lithium value chain. The various materials differ greatly in terms of their lithium content by more than 5 orders of magnitude and also vary in their ...

Kinematics of Spiral Arm Streaming in M51 [PDF]

, 2007
We use CO and H alpha velocity fields to study the gas kinematics in the spiral arms and interarms of M51 (NGC 5194), and fit the 2D velocity field to estimate the radial and tangential velocity components as a function of spiral phase (arm distance). We

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.

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).

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).

Synergies in Self‐Assembly—From Supramolecular Polymers to Defined Hierarchical Superstructures

Journal of Polymer Science, Volume 63, Issue 21, Page 4450-4465, 1 November 2025.
Shaping supramolecular polymers built from molecular building blocks into superstructures with defined dimensions. Synergies within supramolecular architectures such as chirality or an additional second orthogonal driving force that does not interfere with the central supramolecular motif facilitate the confinement of the growth of these ...

Giant Cyclones in Gaseous Discs of Spiral Galaxies

, 2000
We report detection of giant cyclonic vortices in the gaseous disc of the spiral galaxy NGC 3631 in the reference frame rotating with the spiral pattern.

Porphyromonas gingivalis Type 9 Secretion System Promotes Dysregulation of Vascular Smooth Muscle Cell Plasticity With Perturbed TGF‐β/Smad Signaling

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
An intact type 9 secretion system (T9SS) is required for Porphyromonas gingivalis‐mediated dysregulation of aortic smooth muscle cell migration and proliferation. During infection, T9SS also enhanced phosphorylation of multiple sites on transcription factor Smad3 that is implicated in pathologic cell responses to TGF‐β/Smad signaling.
