Two‐Photon Endomicroscopy for Image‐Guided Magnetic Micro‐Agents
Small, EarlyView.Image‐guided manipulation of magnetic micro‐agents requires localized fluorescence feedback capable of resolving dynamic interactions in confined environments. This study introduces a two‐photon endomicroscopy platform for real‐time motion tracking, multicolor micro‐agent discrimination, and imaging through biological tissue.

Adaptive Algorithm for Chirp-Rate Estimation
EURASIP Journal on Advances in Signal Processing, 2009 Chirp-rate, as a second derivative of signal phase, is an important feature of nonstationary signals in numerous applications such as radar, sonar, and communications. In this paper, an adaptive algorithm for the chirp-rate estimation is proposed.

Managing Robot Perception: How Families Present Their Faces to a Toy Robot
Symbolic Interaction, EarlyView.Playing with a robot's face detection capabilities constitutes a praxeological approach to learning about new technology. We explore how family members discover suitable formations for a Cozmo robot to scan a single face, drawing on video recordings from Swedish homes. Taking an ethnomethodology and conversation‐analysis perspective, we demonstrate how

Boreas, EarlyView.Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

Fisheries Management and Ecology, EarlyView.ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

Motion Parameter Estimation of Doppler-Ambiguous Moving Targets in SAR-GMTI [PDF]
, 2007 In an along-track interferometric SAR system, the discrete sampling of moving target signals can give rise to two types of ambiguity: Doppler ambiguity, and interferometric angle ambiguity.

Intrinsic mode chirp decomposition of non-stationary signals
, 2014 We propose the discrete linear chirp transform (DLCT) for decomposing a non-stationary signal into intrinsic mode chirp functions. The decomposition of a signal into a finite number of intrinsic mode functions (IMFs) was introduced by the empirical mode ...

Journal of Electrical and Computer EngineeringSmeared spectrum (SMSP) jamming is a deceptive jamming technique commonly used against linear frequency modulation (LFM) radar. This technique produces high-density false targets that resemble a comb shape after pulse compression processing, resulting in

International Journal of Applied Linguistics, EarlyView.ABSTRACT This article examines the language life of young Malaysian Chinese immigrants in Australia and their construction of multi‐membership as reflected in their daily language behaviors. It develops the concept of everyday linguistic citizenship and uses this concept as a theoretical lens to understand how the young adults build, maintain, and ...
