The NLRP3 inflammasome, a cytosolic complex that mediates the maturation of IL-1β and IL-18 as well release high mobility group box 1 (HMGB1), contributes to lethality endotoxic shock. Ethyl pyruvate (EP) was previously shown inhibit HMGB1 promote survival during endotoxemia experimental sepsis. However, underlying protective mechanism remains elusive. EP dose-dependently inhibited ATP-, nigericin-, alum-, silica-induced caspase-1 activation in mouse macrophages. failed DNA transfection- or...
Ground Penetrating Radar (GPR) is a subsurface sensing technology extensively utilized in various applications. However, the inhomogeneous distribution of medium results stochastic clutter and drastically degrades precision anomalies imaging. To suppress clutter, we introduce deep learning-based cascade network, termed Variational Autoencoder (VAE)-Residual Network (ResNet). It employs unique architecture that integrates VAE ResNet, further enhanced by Residual Feature Distillation Block...
Fast steering mirrors (FSM) are widely used in high precision image stabilization system, which beam adjustment can be realized to enhance the quality of system. mirror is usually fixed optical path and direction changed by adjusting attitude mirror, so as adjust position on imaging platform. Based theory coordinate transformation law light vector reflection, relationship between platform FSM. Shift rotation studied meanwhile. The kinematic model shift high-precision system established,...
Trigeminal schwannoma (TS) is a rare intracranial neurinoma that affects the multicompartmental skull base. In recent decades, advancements in skull-base neurosurgical techniques and endoscopic surgery have significantly improved outcomes for TS patients. this study, we present our experience with surgical resection of using further classification system. We conducted retrospective analysis clinical, surgical, follow-up data 96 patients diagnosed at institution between March 2012 June 2022....
Sepsis, a life-threatening organ dysfunction caused by dysregulated host response to infection, has an approximately 25% in-hospital mortality rate. Identifying early biomarkers of pediatric sepsis is crucial for improving outcomes. This study explored the differential expression peptides in patients with compared healthy controls and those common infections using plasma peptidomic analysis. Blood samples were collected from 10 admitted Hunan Children's Hospital 2021, along 20 age-...
Caspase-11, a cytosolic receptor of bacterial endotoxin (lipopolysaccharide: LPS), mediates immune responses and lethality in endotoxemia experimental sepsis. However, the upstream pathways that regulate caspase-11 activation sepsis are not fully understood. The aim this study is to test whether TIR-domain-containing adapter-inducing interferon-β (TRIF) signaling critical for caspase-11-dependent endotoxemia. Mice indicated genotypes were subjected or cecum ligation puncture (CLP) monitored...
The ground penetrating radar (GPR) data in the complex detection environment is non-stationary, non-Gaussian, and non-uniform, so traditional noise attenuation methods are difficult to meet requirements of denoising. Therefore, we introduced K-singular value decomposition (K-SVD) dictionary learning into denoising GPR signals. It uses orthogonal matching pursuit (OMP) algorithm sparse decompose different trains overcomplete with sample characteristics. K-SVD makes full use prior information...
The high-fidelity attenuation of random ground penetrating radar (GPR) noise is important for enhancing the signal-noise ratio (SNR). In this paper, a novel network structure convolutional denoising autoencoders (CDAEs) was proposed to effectively resolve various problems in process, including overfitting, size local receptive field, and representational bottlenecks vanishing gradients deep learning; approach also significantly improves performance. We described process conventional CDAEs,...
To address problems, such as the computationally intensive inversion requirements, low efficiency, and inadequate accuracy caused by multiparameter crosstalk in a synchronous inversion, new dynamic stochastic source encoding strategy combined with minmax-concave total variation (MCTV) regularization model constraints was proposed. This avoids noise between shots algorithm greatly improves efficiency without affecting accuracy. By comparing "cross"-shaped results, we found that MCTV boasts...
The full-waveform inversion (FWI) of ground-penetrating radar (GPR) data yields promise for quantitatively characterizing the parameters Earth’s shallow subsurface. However, conventional FWI is highly nonlinear and suffers from cycle skipping once low-frequency are missed or initial model poor. Furthermore, having limited prior knowledge subsurface in GPR measurements increases ill-posedness inverse problem. Wavefield reconstruction (WRI), which mitigates skipping, extends search space by...
Due to the unevenness of ground surface, mismatch between trig interval and sampling speed, or other electromagnetic interferences, traces missing is a quite typical occurrence during on-ground penetrating radar (GPR) testing. Effective reconstruction GPR has been regarded crucial link improve both signal-to-noise ratio raw data resolution imaging. In this paper, we propose novel deep-learning framework based on residual feature distillation block U-Net (RFDB-U-Net) mitigate transmission...

Abstract In this study, we investigate the image of a rotating compact object (CO) illuminated by geometrically thin, optically thin disk on equatorial plane. As radius CO’s surface fluctuates, CO may partially or entirely obscure photon region. We observe that perceived ring exhibit discontinuities, deviating from closed structure, and even disappear entirely. find disruption disappearance are dependent observational angle-a novel phenomenon not previously observed in black hole imaging...
Petroclival meningiomas (PCMs) are technically challenging lesions. Although the standard retrosigmoid approach is one of most effective approaches, this route may have some limitations for tumors extending into supratentorial region and middle cranial fossa. We provide a modified surgical technique called retrosigmoid-transtentorial (RTTA) to solve these problems. The feasibility efficacy RTTA were studied, by analyzing neurological outcomes considerations strategies. analyzed 64 71 PCM...
