Doppler polarimetric ground clutter identification and suppression for atmospheric radars based on co-polar correlation, Journal of Telecommunications and Information Technology, 2001, nr 4 [PDF]

open access: yes, 2001
A new clutter suppression technique that uses both Doppler and polarimetric information is presented. Polarimetric properties of the target and clutter are calculated per Doppler frequency cell and based on this information clutter suppression is ...

The social life of money for children

open access: yesThe British Journal of Sociology, EarlyView.
Abstract Inspired by Nigel Dodd's The Social Life of Money, this article proposes an analysis of entangled economic lives, that is, how meaning, structures and politics jointly shape the flow of monies within households. The past decades have marked a shift from “childrearing expenditures” to “parenting investments” that align with new visions of both ...

Spectral polarimetric radar clutter suppression to enhance atmospheric echoes

open access: yes, 2009
The clutter present in the Doppler spectra of atmospheric targets can be removed by using polarimetry. The purpose is to suppress the Doppler velocity bins where spectral polarimetric parameters have atypical values.

Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat

open access: yesIntegrative Zoology, EarlyView.
After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...

TreeSegAgent: Agentic tree instance segmentation via a multi‐anchor pipeline

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Individual‐tree segmentation from three‐dimensional forest point clouds underpins forest inventory, biomass estimation and ecosystem monitoring, but remains challenging in structurally complex stands, where vertical heterogeneity and point‐density degradation weaken the robustness of centre‐offset‐based instance grouping.

Clinical features of mental imagery in substance use disorders: A mixed‐methods analysis

open access: yesAddiction, EarlyView.
Abstract Aims To characterise the frequency, features and content of craving‐related mental imagery among people seeking treatment for substance use disorders (SUDs); examine within‐session change in self‐reported craving following imagery elicitation; and explore perceived links with autobiographical memory, behavioural, cognitive and emotional ...

The Impact of Common Medications on Male Fertility: An Updated Systematic Review

open access: yesAndrology, EarlyView.
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...

Space-time Two-dimensional Clutter Suppression Method Based on Subarray Beam Pattern Design

open access: yesLeida xuebao
Airborne radar receivers that utilize subarray processing face challenges owing to the complex space-time coupling distribution caused by grating-lobe clutter.
