Plasticity of the heart in response to changes in physical activity

The Journal of Physiology, EarlyView.
Abstract figure legend The heart adapts to changes in physical activity, with inactivity (e.g. bed rest or spaceflight) causing cardiac atrophy and ventricular stiffening, and endurance exercise training leading to eccentric hypertrophy and improved ventricular compliance.

A high resolution CO map of the inner region of M51 [PDF]

, 1998
M51, the Whirlpool Galaxy, at a distance of ≈ 9,6 Mpc and a systemic velocity of 465 km s^(−1), is the closest “Grand Design” spiral galaxy. Its low inclination (20°) makes it an excellent target for structural studies, e.g.

Simulations of dual morphology in spiral galaxies [PDF]

, 2002
Gas and stars in spiral galaxies are modelled with the DUAL code, using hydrodynamic and N-body techniques. The simulations reveal morphological differences mirroring the dual morphologies seen in B and K' band observations of many spiral galaxies.

Commodity risk assessment of Populus alba, Populus nigra and Populus tremula plants from the UK

EFSA Journal, Volume 23, Issue 3, March 2025.
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Populus alba, Populus nigra and ...

Unusual Drainages of the Americas

Water Resources Research, Volume 61, Issue 2, February 2025.
Abstract While most rivers and lakes follow predictable principles of hydrology and geology, a few seem to defy the rules. Some rivers diverge rather than converge; some rivers flow in two directions; some lakes have not one but two outlets; some watersheds have ambiguous boundaries.

Search for pre‐accretionary irradiation effects in calcium‐aluminum inclusions from the CV3 chondrite Allende

Meteoritics &Planetary Science, Volume 60, Issue 2, Page 247-272, February 2025.
Abstract Calcium‐aluminum‐rich inclusions (CAIs) are the first objects that formed in the solar accretion disk and therefore provide valuable insights into the evolution of the early solar system. A long‐standing question regarding this earliest formative period relates to the storage of CAIs in the 1–4 Myr time period between their formation and later

Hα kinematics of S^(4)G spiral galaxies – I. NGC 864 [PDF]

, 2012
We present a study of the kinematics of the isolated spiral galaxy NGC 864, using Hα Fabry–Perot data obtained with the Galaxy Hα Fabry–Perot System (GHαFaS) instrument at the William Herschel Telescope in La Palma, complemented with images at 3.6 μm, in

Modular Tunable α‐Helical Peptide Hydrogels for Neuronal Cells

Advanced Functional Materials, Volume 35, Issue 1, January 2, 2025.
Rationally designed peptides are used to alter the elastic properties of α‐helical hydrogels, to introduce adhesion peptides and growth factors, and to spatially pattern proteins. The modularity of the hydrogelating self‐assembling fiber (hSAF) system provides a flexible platform for manipulating primary neural cell behavior, with potential future ...

The Shearing HI Spiral Pattern of NGC 1365

, 2011
The Tremaine-Weinberg equations are solved for a pattern speed that is allowed to vary with radius. The solution method transforms an integral equation for the pattern speed to a least squares problem with well established procedures for statistical ...

An Algebraic Approach to Light–Matter Interactions

Advanced Physics Research, Volume 4, Issue 1, January 2025.
This is a review of an algebraic approach to light–matter interactions that is theoretically powerful and computationally friendly. Theoretical expressions can be developed and manipulated conveniently thanks to the generality of the basis on which the approach rests, and a compact notation.
