Fluorescence molecular tomography (FMT) plays an important role in studying physiological and pathological processes of small animals vivo at level. However, this technique suffers from relatively low spatial resolution. To complement the problem, there has been a strong demand for providing functional morphological analysis same time. In paper, we proposed hybrid full-angle free-space FMT X-ray micro-cone-beam computed (CT) (micro-CBCT) prototype system, both anatomical images. During whole...
The knowledge of optical properties distribution heterogeneous media has significant impact on the reconstructed fluorescence image quality in molecular tomography (FMT). In this study, a novel finite-element-based algorithm for FMT is proposed. algorithm, are using conjugate gradient method. A modified method based reverse differential scheme deduced calculating when detector points not restricted boundary nodes. With recovered properties, linear relationship between known surface...
For conventional bandwidth extension, the spectral patching methods, such as folding, translation and non-linear processing, are employed to reconstruct high frequency signal, yet it leads shifting between reconstructed original does not retain harmonic relations. In this paper, a blind extension method from wideband super-wideband was proposed by estimating energy of envelope with Gaussian mixture model (GMM). Both objective subjective test results show that algorithm performs better than...
Challenges remain in imaging fast biological activities through whole small animal using fluorescence diffuse optical tomography (FDOT). In this study, a novel full-angle FDOT with spatially coded parallel excitation (SC-FDOT) is proposed, which provides much better image qualities than our previous multiple-points illumination (MP-FDOT) while maintaining comparable temporal resolution. Singular-value analysis and numerical simulations are used to obtain the key experimental parameters...
Being in a confined environment causes chronic stress gestating sows, which is detrimental for sow health, welfare and, consequently, offspring physiology. This study assessed the health and of sows housed group housing system compared to individual gestation stalls. After pregnancy was confirmed, experimental were divided randomly into two groups: (GS), with electronic feeding (ESF) system; or stall (IS). The behavior GS IS then compared; throughout pregnancy, displayed more exploratory...
Mobile stereo matching systems are becoming more important in many applications such as auto-driving and autonomous robots. However, to maintain its low power consumption, mobile platforms have only limited hardware resources. Accurate methods require a high computational complexity, it is difficult both acceptable accuracy processing speed on the platforms. To solve this trade-off, paper, we propose novel acceleration approach for well-known algorithm Zero-means Normalized Cross Correlation...
<title>Abstract</title> Observing the dynamics of colorless or transparent samples quantitatively is vital in cellular-level biomedical research. Among existing techniques, fluorescent microscopy suffers from phototoxicity and photobleaching issues, while snapshot quantitative phase imaging (QPI) demands a complicated setup. Thus, an easily accessible tool allowing for long-period, high-contrast observation remains still lacking. To tackle this problem, we propose one-shot QPI approach...
In this paper, short reference code index differential chaotic shift keying can enhance the security performance of system in space laser communication system. Through transmission picture information, confidentiality is analyzed. The pixel correlation analysis, statistical histogram, and plaintext sensitivity prove that has high performance.
The wireless communication network has a huge promotion effect on data processing. As an important standard for internet transmission, XML markup language is currently widely used in the internet. rapid development of brought fresh blood to research database. This article aimed at studying application storage metadata database Wushu Historical Archives. One part uses load‐balancing algorithms and two‐way path constraint conduct databases, such as document size, loading, query. Combining...
In this paper, a deterministic nonlinear model, i.e., the TCP-RED feedback system is adopted to simulate complex computer network.The phase-space reconstruction applied reveal hidden information of rate which could be obtained from Internet easily.In addition, maximum Lyapunov exponent judge stability system.The research demonstrates those two different parameters affect system's stability.To avoid evolving into chaos state, routers must configured properly.
