Director Field Model of the Primary Visual Cortex for Contour Detection
, 2014 We aim to build the simplest possible model capable of detecting long, noisy contours in a cluttered visual scene. For this, we model the neural dynamics in the primate primary visual cortex in terms of a continuous director field that describes the ...

The social life of money for children
The 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 ...

Velocity Dealiased Spectral Estimators of Range Migrating Targets using a Single Low-PRF Wideband Waveform [PDF]
, 2013 Wideband radars are promising systems that may provide numerous advantages, like simultaneous detection of slow and fast moving targets, high range-velocity resolution classification, and electronic countermeasures.

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

Target detection in high-resolution sea clutter via block-adaptive clutter suppression
IET Radar, Sonar & Navigation, 2011 Attentions have been focused on the moving target detection in a high-resolution sea clutter. This study commences with a proposal of median-based estimator to estimate the power spectrum of high-resolution sea clutter by the time series observed in adjacent range cells and time intervals.

Critical Quarterly, EarlyView.Abstract ‘I have to share a bathroom’, I had so often murmured, almost with shame, as if I personally had been found unworthy of a bathroom of my own. Barbara Pym, Excellent Women (1952) For a single woman of a certain age, living alone in postwar London, austerity was more than a set of political and economic imperatives.

Leida xuebao, 2015 In a high pulse-repetitive-frequency forward-looking radar, the clutter echo is not only severely rangedependent but also range-ambiguous. It is therefore difficult to realize clutter compensation and suppression for conventional Space-Time Adaptive ...

Sea Clutter Suppression for Shipborne DRM-Based Passive Radar via Carrier Domain STAP
Remote SensingThis paper proposes a new carrier domain approach to suppress spreading first-order sea clutter in shipborne passive radar systems using Digital Radio Mondiale (DRM) signals as illuminators.

Research on Polarization Cancellation of Nonstationary Ionosphere Clutter in HF Radar System
International Journal of Antennas and Propagation, 2015 Oblique projection polarization filter (OPPF) can be applied as an effective approach for interference cancellation in high-frequency surface wave radar (HFSWR) and other systems. In order to suppress the nonstationary ionosphere clutter further, a novel
