Fractal Tilings Based on Successive Adjacent Substitution Rule

A fractal tiling or -tiling is a tiling which possesses self-similarity and the boundary of which is a fractal. -tilings have complicated structures and strong visual appeal. However, so far, the discovered -tilings are very limited since constructing such -tilings needs special talent. Based on the idea of hierarchically subdividing adjacent tiles, this paper presents a general...

Reducing Subspaces of the Dual Truncated Toeplitz Operator

We define the dual truncated Toeplitz operators and give some basic properties of them. In particular, spectrum and reducing subspaces of some special dual truncated Toeplitz operator are characterized.

Dynamic Characteristics of Blade with Viscoelastic Damping Block Based on Complex Eigenvalue Method

A novel method for vibration suppression is proposed, adding a viscoelastic damping block to the root of the blade. The dynamical equation for a rotational viscoelastic damping block-blade (VE-blade) in a centrifugal force field and aerodynamic force field is established to calculate the dynamical natural frequency and responses of the VE-blade. Complex modulus model is applied...

Determination of Residual Stress and Design of Process Parameters for Composite Cylinder in Filament Winding

As there is increasing usage of composite components with a closed-end shape, filament winding technology has been applied extensively in engineering practice. However, the residual stresses are readily caused by process parameters in composite manufacturing process. Hence, it is necessary to design the reasonable process parameters for obtaining the expected residual stresses...

3D Reconstruction from a Single Still Image Based on Monocular Vision of an Uncalibrated Camera

we propose a framework of combining Machine Learning with Dynamic Optimization for reconstructing scene in 3D automatically from a single still image of unstructured outdoor environment based on monocular vision of an uncalibrated camera. After segmenting image first time, a kind of searching tree strategy based on Bayes rule is used to identify the hierarchy of all areas on...

Lactate as a Potential Biomarker of Sepsis in a Rat Cecal Ligation and Puncture Model

We attempted to investigate whether blood lactate is a useful biomarker for sepsis in a rat cecal ligation and puncture (CLP) model. Male Sprague-Dawley rats underwent approximately 75% cecum ligation and two punctures to induce high-grade sepsis. A lactate of 1.64 mmol/L (Youden score of 0.722) was selected as the best cutoff value to predict the onset of sepsis after CLP...

Correction to: Simultaneous Modification of Alumina and MgO·Al2O3 Inclusions by Calcium Treatment During Electroslag Remelting of Stainless Tool Steel

In Table III, the correct value of first-order interaction parameter of Cr on S should be −0.0105, rather than 0.0105. It should be stressed that the thermodynamic calculation associated with this parameter was performed using \( e_{\text{S}}^{\text{Cr}} \) = − 0.0105 in the published article. Thus, all calculated results associated with this parameter are correct in this article.

PLK1 protects against sepsis-induced intestinal barrier dysfunction

Sepsis and sepsis-associated intestinal barrier dysfunction are common in intensive care units, with high mortality. The aim of this study is to investigate whether Polo-like kinase 1 (PLK1) ameliorates sepsis-induced intestinal barrier dysfunction in the intestinal epithelium. The mouse intestinal barrier was disrupted after Lipopolysaccharide (LPS) injection due to intestinal...

Data Analysis and Modeling of Chilled Water Loops in Air Conditioning Systems

Artificial neural network has been widely used in air conditioning systems as an effective method for predicting parameters, and the accuracy of ANN model relies on training data and network structure.

Quasi-Spherical Brookite TiO2 Nanostructures Synthesized Using Solvothermal Method in the Presence of Oxalic Acid

Brookite TiO2, the latest TiO2 photocatalyst, promises to be an interesting candidate for photocatalytic applications because of its unique physical and chemical properties. In this study, pure-phase brookite TiO2 with a quasi-spherical nanostructure was successfully synthesized via a solvothermal method using tetrabutyl titanate (Ti(OC4H9)4, TBOT) as the Ti source in the...
