Quantitative analysis of channel characteristics of distributive fluvial systems

Sedimentology, Volume 73, Issue 5, Page 1606-1630, August 2026.
ABSTRACT Distributive fluvial systems (DFSs) are characterised by a radial distributive channel pattern in planform and dominate modern‐day sedimentary basins. Where aggradation occurs, such as in sedimentary basins, there is increased preservation potential, and therefore, DFSs are hypothesised to constitute a significant portion of the continental ...

Basics and Perspectives of Visible and Near‐UV Light‐Induced Defluorination of Perfluoroalkylsubstances by Semiconductor Nanocrystals

ChemPhotoChem, Volume 10, Issue 6, June 2026.
This review highlights recent advances in the light‐driven destruction of persistent per‐ and polyfluoroalkyl substances (PFASs) using semiconductor nanocrystals. By exploiting nonlinear photophysical and photochemical processes, these nanomaterials harness energy‐efficient visible and near‐UV light‐emitting diodes (LEDs) to drive extreme reduction ...

Iterative amplitude/phase multiple-symbol differential sphere detection for DAPSK modulated transmissions

, 2012
Differentially encoded and non-coherently detected transceivers exhibit a low complexity, since they dispense with complex channel estimation. Albeit this is achieved at the cost of requiring an increased transmit power, they are particularly beneficial,

Seasonal Flooding Disrupts Expected Depth‐Dependent Patterns of Mineral Associated Carbon, Nitrogen, and Phosphorus Across Land Uses

Global Change Biology, Volume 32, Issue 4, April 2026.
The subsoil (< 30 cm) stores ~25%–70% of soil organic matter (OM), rendering it critical for carbon (C), nitrogen (N), and phosphorus (P) persistence. Our understanding of how OM cycles down the soil profile largely comes from well‐drained soils. Yet seasonal flooding can destabilize mineral‐associated organic matter (MAOM), the most persistent OM pool,

Elliptical Orbit Representation for the Annual Evolution of the Northern Hemisphere Stratospheric Polar Vortex. Part I: Diagnosing Interannual Variability

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Using a single annual frequency with each year defined from July 1 to June 30 of the following calendar year, this study fits an ellipse to the yearly phase space trajectory of the daily time series of MU (stratospheric mass‐weighted zonally integrated zonal wind at 60°N) and M (total polar stratospheric air mass over 60–90°N) to represent the

Intensity dependent residual amplitude modulation in electro-optic phase modulators

, 2012
Residual amplitude modulation (RAM) mechanisms in electro-optic phase modulators are detrimental in applications that require high purity phase modulation of the incident laser beam.

(Remembering) Vector Coding of Boundaries and Objects in the Subiculum

Hippocampus, Volume 36, Issue 2, March 2026.
ABSTRACT This review offers a personal and historical perspective on spatial representations of the local environment in hippocampal regions CA1 and subiculum, as derived from extracellular electrophysiological recording of neurons in these regions in freely behaving rodents.

Hardware‐Accurate Simulation and Performance Analysis of Free Space Optical Communication Systems

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper presents a system‐level performance evaluation of a 10 Mbps free‐space optical (FSO) communication link using a novel dual‐testbed methodology. By combining hardware‐accurate profiling in Keil μ$\umu$ Vision for the STM32H755ZI microcontroller with physical layer simulations in Proteus, we successfully isolate embedded processing constraints

Near-Capacity Irregular Bit-Interleaved Coded Modulation [PDF]

, 2008
An Irregular Bit-Interleaved Coded Modulation based Iterative Decoding (Ir-BICM-ID) aided scheme is proposed. The irregularity of the scheme pervades the three basic components of BICM-ID, namely the encoder, the unity-rate precoder and the bit-to-symbol
