Study on the elimination characteristics of smoke particles with different materials using electric agglomeration technology.

Fire smoke, consisting of solid particles and liquid droplets, poses risks of asphyxiation, poisoning, making it a significant contributor to fire-related fatalities and environmental pollution. The exploration of effective smoke control methods represents a vital approach to reducing the threat of fire smoke to public health and safety. This study aims to determine the characteristics of elimination for the fire smoke generated from burning four typical materials, thereby validating the universality of electric agglomeration smoke elimination technology.

Incorporating Heterogeneous Features into the Random Subspace Method for Bearing Fault Diagnosis.

In bearing fault diagnosis, machine learning methods have been proven effective on the basis of the heterogeneous features extracted from multiple domains, including deep representation features. However, comparatively little research has been performed on fusing these multi-domain heterogeneous features while dealing with the interrelation and redundant problems to precisely discover the bearing faults. Thus, in the current study, a novel diagnostic method, namely the method of incorporating heterogeneous representative features into the random subspace, or IHF-RS, is proposed for accurate bearing fault diagnosis.

Experience in the treatment of chlorfenapyr poisoning.

In China, the extensive use of the pesticide chlorfenapyr has led to an increase in chlorfenapyr poisoning. However, there are limited reports on chlorfenapyr poisoning, and most of them are fatal cases. This study retrospectively analyzed four patients admitted to the emergency room after chlorfenapyr intake and detected different concentrations of chlorfenapyr in their plasma.

Remodeling process and clinical outcomes following all-arthroscopic modified Eden-Hybinette procedure using iliac crest autograft and 1-tunnel double Endobutton fixation system.

Background: Arthroscopically modified Eden-Hybinette procedures for glenohumeral stabilization have been used for a long time. With the advancement of arthroscopic techniques and the development of sophisticated instruments, a double Endobutton fixation system has been used clinically to secure bone graft to the glenoid rim placed through a specifically designed guide. The purpose of this report was to evaluate clinical outcomes and serial glenoid remodeling process following all-arthroscopic anatomical glenoid reconstruction using autologous iliac crest bone grafting technique through 1-tunnel fixation.

Follow-up of patients with a 5-year survival after paraquat poisoning using computed tomography images and spirometry.

Objectives: The study aimed to examine long-term survival of patients with acute paraquat poisoning using computed tomography (CT) images and spirometry.

Concise fractional Fourier transform based on a non-uniform order searching method for estimating physical parameters from Newton's rings.

Newton's ring pattern is very common in interferometry. By analyzing it, the physical parameters can be estimated, such as the curvature radius and the rings' center. However, parameter estimation from large images using fractional Fourier transform (FRFT) consumes considerable time.

Arthroscopic Autologous Iliac Crest Bone Grafting for Reconstruction of the Glenoid: A Nonrigid Fixation Technique.

Massive glenoid bone loss in recurrent anterior instability of the shoulder represents a surgical challenge. Some clinical trials have been published assessing the role of arthroscopic iliac crest bone grafting techniques for the management of recurrent anterior instability with glenoid bone loss. However, bone graft fixation is still controversial.

[Two case reports: chronic obstructive pulmonary disease developed in long term survived patients after acute paraquat poisoning].

Patients with acute paraquat poisoning mostly die of respiratory failure, and the surviving ones may live with pulmonary fibrosis, but the long-term changes in lung function are still un-clear.

Arthroscopy Primary Double-Bundle Repair of Anterior Cruciate Ligament With Internal Brace Augmentation and a Knotless Anchor Implant.

The primary repair technique of acute anterior cruciate ligament (ACL) tears has been controversially discussed over the past few decades. Many different suture techniques have been reported for ACL repair, but these procedures showed high re-rupture rates and poor results. Recently, the literature has reported excellent outcomes with primary ACL repair.

Methods: This meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Fast FRFT-based method for estimating physical parameters from Newton's rings.

By analyzing Newton's rings, often encountered in interferometry, using fractional Fourier transform (FRFT), we can estimate the physical parameters, such as the curvature radius of the spherical surface and the rings' center. However, parameter estimation from large images using FRFT consumes considerable time. We introduce an improved method that resamples the image before applying FRFT.

Impact of background and modulation on parameter estimation using fractional Fourier transform and its solutions.

Analysis of closed-fringe patterns with quadratic phase that are often encountered plays an important role in optical interferometry. But because the frequency spectra of the two exponential signals that compose closed-fringe patterns overlap in the Fourier domain while one is clearly distinct from the other in the fractional Fourier domain, fractional Fourier transform (FRFT) is a useful method for analyzing the images to provide parameter estimation. However, when the fringe pattern has varying background and/or modulation due to non-uniform illumination, parameter estimation accuracy based on FRFT is affected, which lacks theoretical justification.

E3 ubiquitin ligase tripartite motif 7 positively regulates the TLR4-mediated immune response via its E3 ligase domain in macrophages.

Members of the tripartite motif (TRIM) family as E3 ubiquitin ligases have been regarded as critical regulators of innate immunity and antiviral response. However, the role of TRIM7 is still elusive. Here, we provide evidence for the importance of TRIM7 in regulation of the TLR4-mediated innate response.

Furin Cleavage of L2 during Papillomavirus Infection: Minimal Dependence on Cyclophilins.

Unlabelled: Despite an abundance of evidence supporting an important role for the cleavage of minor capsid protein L2 by cellular furin, direct cleavage of capsid-associated L2 during human papillomavirus 16 (HPV16) infection remains poorly characterized. The conserved cleavage site, close to the L2 N terminus, confounds observation and quantification of the small cleavage product by SDS-PAGE. To overcome this difficulty, we increased the size shift by fusing a compact protein domain, the Propionibacterium shermanii transcarboxylase domain (PSTCD), to the N terminus of L2.
