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.

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 ...

Techniques for homodyne dechirp-on-receive linearly frequency modulated radar [PDF]
, 2011 This thesis presents work done to extend and improve the operation of homodyne dechirp-on-receive linearly frequency modulated radars. First, an investigation of the effect of common phase errors on the point response function of the radar is ...

Forward Generation of the GW150914 Gravitational-Wave Signal from a Constrained Propagation Model
Reports in Advances of Physical SciencesThis work tests whether a source–observer propagation relation calibrated independently from Pantheon+ Type Ia supernova data can forward-generate the GW150914 gravitational-wave (GW) chirp when applied unchanged in the gravitational-wave domain.

Detection of LFM Radar Signals and Chirp Rate Estimation Based on Time-Frequency Rate Distribution
Sensors, 2021 Linear frequency-modulated (LFM) signals are the most significant example of waveform used in low probability of intercept (LPI) radars, synthetic aperture radars and modern communication systems.

Sound offset responses become highly informative in the auditory cortex
The Journal of Physiology, EarlyView.Abstract figure legend Using large datasets of neural responses to diverse sounds recorded across four stages of the mouse auditory system (depicted and colour‐coded on the left), offset responses occurring after the termination of each sound (time window indicated by the orange shaded area superimposed with activity traces) were characterized and it ...

Image Encoding With Blipped Gradients in an Echo Train
Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2530-2538, November 2026.ABSTRACT Purpose An MRI scanner was designed and built to encode k‐space points in the spin echoes occurring between 180∘ pulses in an echo train by using blipped B0 gradient pulses applied just prior to those spin echoes. Methods The proposed MRI scanner is a modification of an original design that used TRansmit Array Spatial Encoding (TRASE), a built‐

Allpass-Based Chirp Design With Perfect Pulse Compression Property
IEEE Open Journal of Signal ProcessingChirp waveforms are widely used in radar, sonar, acoustics, and other sensing systems due to their desirable pulse-compression behavior. However, standard chirp signals like linear frequency modulation (LFM) waveforms inevitably produce sidelobes that ...

Experimental Analysis of Chirp Waveforms for Wireless Power Transfer
2024 International Wireless Communications and Mobile Computing (IWCMC)In this paper, we present an experimental analysis of far-field wireless power transfer (WPT) using radio frequency (RF) signals. The dual capability of RF signals for power and information transfer drives the integration of WPT and communication systems. The objective is to experimentally validate different waveforms intended for WPT and compare their

Ultra‐High Isolation Decoupling and Matching Network for mmWave Antennas in Near‐Range FMCW Radars
Microwave and Optical Technology Letters, Volume 68, Issue 10, October 2026.ABSTRACT A decoupling and matching network (DMN) based on substrate integrated coaxial line technique is proposed to suppress the mutual coupling between a pair of transmitting and receiving antennas operating at 35 GHz. The distorted radiation patterns, typically observed in closely spaced antennas, were improved by introducing carefully designed ...
