The next generation of synthetic aperture radar (SAR) systems will need transmit and receive analog signals over a wide frequency range with large bandwidth to fulfil the increasing demands. Since performance digital microwave component is deteriorated at frequency, radio (RF) front-end capability conversion needed for beyond few gigahertz. However, widely employed RF mixers, inherent imperfect I-V characteristics nonlinear devices, generates many undesired mixing spurs, which restricts on...
Rail head surface defect detection is a major issue for rail maintenance, which mainly used to avoid railway accidents due track failures. The aim of this paper present new vision based inspection technique detecting special Rolling Contact Fatigue (RCF) defects that particularly occur on surface, meanwhile, an automatic system implemented, consists pre-processing, locating, identifying and post-processing subsystems. To realize the locating sub-procedure, simple fast algorithm has been...
Biological hydroxyapatite, derived from animal bones, is the most widely used bone substitute in orthopedic and dental treatments. Fluorine trace element involved remodeling has been confirmed to promote osteogenesis when administered at appropriate dose. To take advantage of this knowledge, fluorinated porcine hydroxyapatite (FPHA) incorporating increasing levels fluoride was cancellous through straightforward chemical thermal Physiochemical characteristics, including crystalline phases,...
As the main inorganic component of xenogenic bone graft material, bone-derived biological apatite (BAp) has been widely used in implant dentistry, oral and maxillofacial surgery orthopedics. However, BAp produced via calcination animal bones still suffers from some drawbacks, such as insufficient mechanical strength inadequate degradation rate, which impede its application. Fluoride is known to play important roles both physiological pathological processes human hard tissues for double...
The problem of echo separation using digital beamforming (DBF) on receive for multiple-input multiple-output (MIMO) synthetic aperture radar (SAR) is notable importance to allow practical systems. Regrettably, current DBF-MIMO-SAR schemes, such as the short-term shift-orthogonal (STSO) scheme, are computationally cumbersome, increasing required hardware complexity. To alleviate this problem, we here propose an improved solution realizing a low-cost MIMO-SAR system. We detail generic waveform...
Abstract Semantic control refers to the ability flexibly retrieve and manipulate stored knowledge support context-appropriate behavior. A left-lateralized network comprising left inferior frontal gyrus (IFG), posterior middle temporal (pMTG), dorsal medial prefrontal cortex (dmPFC) has been consistently implicated in this process. While previous studies have established necessity of IFG pMTG semantic control, causal role dmPFC remains unclear. Additionally, it is unknown whether each these...
Abstract Vertebrate locomotion is orchestrated by spinal interneurons making up a central pattern generator. Proper coordination of activity, both within and between segments, required to generate the desired locomotor output. This altered during acceleration ensure correct recruitment muscles for chosen speed. The transcription factor Dmrt3 has been proposed shape patterned output at different gaits in horses mice. Here, we characterized dmrt3a mutant zebrafish, which showed strong,...
We investigate the problem of obtaining dense 3D reconstruction from airborne multi-aspect synthetic aperture radar (SAR) image sequences. Dense reconstructions multi-view SAR images are vulnerable to anisotropic scatters. To address this issue, we propose a probabilistic method based on jointly estimating pixel’s height and degree anisotropy. Specifically, mixture distribution model for stereo-matching results, where anisotropy is modeled as an underlying error source. Then, Bayesian...
In this article, we present a novel synthetic aperture radar (SAR) 3-D imaging strategy using circular Interferometric SAR (InSAR) data. Our approach improves upon the Holographic tomography (HoloSAR) techniques by eliminating need for multi-baseline data collection nor residual motion error correction over long curvilinear aperture. This may provide simple yet effective solution perturbed airborne platforms. The key innovation is first utilization of multi-aspect interferograms to invert or...
Optical projection tomography (OPT) is a 3D imaging alternative to conventional microscopy which allows of millimeter-sized object with isotropic micrometer resolution.

Circular synthetic aperture radar (CSAR) has the potential to form 3D images with single-pass single-channel data, which is very time-efficient. This article proposes a volumetric neural renderer that utilizes CSAR 2D amplitude reconstruct power distribution of imaged scene. The innovations are two-fold: Firstly, we propose new SAR image formation model establishes linear mapping relationship between multi-look amplitude-squared and real-valued 4D (spatial location (x, y, z) azimuth angle θ)...
