Observations of Small‐Scale Heterogeneity in the Upper Mantle Beneath Old Oceanic Lithosphere

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract We present tomographic images of the velocity structure of the upper mantle beneath old (∼90 ${\sim} 90$ Ma) oceanic lithosphere, derived from arrival time measurements of teleseismic body waves recorded by ocean‐bottom seismometers. Differential travel time measurements on P, S, and SKS body waves across a wide range of frequency bands show ...

Image simulations for gravitational lensing withskylens [PDF]

Monthly notices of the Royal Astronomical Society, 2018
We present the latest version of the ray-tracing simulation code SKYLENS, which can be used to develop image simulations that reproduce strong lensing observations by any mass distribution with a high level of realism.

Rethinking Global Soil Degradation: Drivers, Impacts, and Solutions

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The increasing threat of soil degradation presents significant challenges to soil health, especially within agroecosystems that are vital for food security, climate regulation, and economic stability. This growing concern arises from intricate interactions between land use practices and climatic conditions, which, if not addressed, could ...

Intrinsic alignments of group and cluster galaxies in photometric surveys [PDF]

, 2014
Intrinsic alignments of galaxies have been shown to contaminate weak gravitational lensing observables on linear scales, $r>$ 10 $h^{-1}$Mpc, but studies of alignments in the non-linear regime have thus far been inconclusive.

Staged ecologies: Aesthetics, nature and infrastructure in the late‐modern metropolis

Transactions of the Institute of British Geographers, Volume 50, Issue 4, December 2025.
Short Abstract This paper examines the relationship between urban nature and landscape design within a £1.5 billion regeneration project that is currently unfolding in Thamesmead, a town in south‐east London. It develops the notion of ‘staged ecologies’ to examine how urban nature is being spatially and aesthetically arranged across the town's ...

$f(R)$ gravity theories in the Palatini Formalism constrained from strong lensing

, 2009
$f(R)$ gravity, capable of driving the late-time acceleration of the universe, is emerging as a promising alternative to dark energy. Various $f(R)$ gravity models have been intensively tested against probes of the expansion history, including type Ia ...

Efficient and Realistic Brain Simulation: A Review and Design Guide for Memristor‐Based Approaches

Advanced Materials Technologies, Volume 10, Issue 17, September 4, 2025.
Memristor‐based emulation of Hodgkin‐Huxley neuron models is investigated, by defining the ideal device characteristics needed for accurate ion‐channel representation and reviewing existing works targeting memristive replication of biological realistic neural behavior.

Relational Supersymmetry via the Dressing Field Method and Matter‐Interaction Supergeometric Framework

Annalen der Physik, Volume 537, Issue 9, September 2025.
Applications of the Dressing Field Method are reviewed and further expanded to the very foundations of the supersymmetric framework, where it allows to build relational supersymmetric field theory. Furthermore, a novel approach is proposed giving a unified description of fermionic matter fields and bosonic gauge fields: a Matter‐Interaction ...

Lensing by Kerr Black Holes. I: General Lens Equation and Magnification Formula

, 2011
We develop a unified, analytic framework for gravitational lensing by Kerr black holes. In this first paper we present a new, general lens equation and magnification formula governing lensing by a compact object. Our lens equation assumes that the source

Projected Constraints on Modified Gravity Cosmologies from 21 cm Intensity Mapping [PDF]

, 2010
We present projected constraints on modified gravity models from the observational technique known as 21 cm intensity mapping, where cosmic structure is detected without resolving individual galaxies.
