Topology Optimization Analysis of Separation Mechanism for the Rice Trans-Planter

A mechanical topology regeneration design method based on the basic chain was presented which was reducing invalid topology design workload and improving optimization design efficiency. And it is used for configuration topology research of planetary separation mechanism of rice transplanting machine to verify its feasibility and effectiveness, which mainly consists of crank...

Controlled cooling of an aluminum alloy casting based on 3D printed rib reinforced shell mold

3D printing technology has been used for sand molding and core printing, but they simply substitute the traditional molding and core making method without changing the shape or size of the sand mold (core) and their dense structure. In this study, a new type of hollow mold based on 3D printing is presented. The new type of mold is a rib reinforced thickness-varying shell mold...

Fabrication of a Porous Metal-Organic Framework with Polar Channels for 5-Fu Delivery and Inhibiting Human Osteosarcoma Cells

As an emerging kind of crystalline material, the metal-organic framework (MOF) has shown great promise in the biomedical domains such as drug storage and delivery. In this study, a new porous MOF, [[Dy2(H2O)3(SDBA)3](DMA)6] (1, H2SDBA = 4,4′-sulfonyldibenzoic acid, DMA = N,N-dimethylacetamide (C4H9NO)), with uncoordinated O donor sites has been fabricated using a bent...

What circumstances lead to non-disclosure of cancer-related information in China? A qualitative study

Background Withholding information from cancer patients is a common practice in many Asian countries, including China, Japan, and Singapore, as well as in some Western countries, such as Spain, Greece, and Italy. Much research has investigated why doctors withhold information from cancer patients generally, both in the West and the East, but little research has been done on...

Insulation effect of air cavity in sand mold using 3D printing technology

The insulation effect of the air cavity surrounding the riser in a 3D printed sand mold was studied. The influence of the air cavity on heat flux was theoretically analyzed. The results demonstrated that the heat flux of the air cavity in the 3D printed sand mold was significantly less than that of resin-bonded sand. The insulation effect of the air cavity in sand molds for a...

The \(\varvec{\Lambda _b\rightarrow \Lambda (\rightarrow p\pi ^-)\mu ^+\mu ^-}\) decay in the aligned two-Higgs-doublet model

The rare baryonic decay \(\Lambda _b\rightarrow \Lambda (\rightarrow p\pi ^-)\mu ^+\mu ^-\) provides valuable complementary information compared to the corresponding mesonic \(b\rightarrow s\mu ^+\mu ^-\) transition. In this paper, using the latest high-precision lattice QCD calculation of the \(\Lambda _b\rightarrow \Lambda \) transition form factors, we study this interesting...

\(\varvec{B^0\rightarrow K^{*0}\mu ^+\mu ^-}\) decay in the aligned two-Higgs-doublet model

In the aligned two-Higgs-doublet model, we perform a complete one-loop computation of the short-distance Wilson coefficients \(C_{7,9,10}^{(\prime )}\), which are the most relevant ones for \(b\rightarrow s\ell ^+\ell ^-\) transitions. It is found that, when the model parameter \(\left| \varsigma _{u}\right| \) is much smaller than \(\left| \varsigma _{d}\right| \), the charged...

Dynamic changes in biomarkers in acute human immunodeficiency virus infections: a case report

Background The highest incidence of human immunodeficiency virus infection in China is among men who have sex with men. This case report aims to describe the dynamic changes in biomarkers in an acute human immunodeficiency virus infection of a Han Chinese man who has sex with men, and to illustrate the possibility of using these biomarkers for the early detection of human...

Spatial measurement errors in the field of spatial epidemiology

Background Spatial epidemiology has been aided by advances in geographic information systems, remote sensing, global positioning systems and the development of new statistical methodologies specifically designed for such data. Given the growing popularity of these studies, we sought to review and analyze the types of spatial measurement errors commonly encountered during spatial...

Burkholderia pseudomallei-derived miR-3473 enhances NF-κB via targeting TRAF3 and is associated with different inflammatory responses compared to Burkholderia thailandensis in murine macrophages

Background Burkholderia pseudomallei (Bp) is the causative agent of melioidosis, a kind of tropical disease. Burkholderia thailandensis (Bt), with a high sequence similarity to Bp, is thought to be an avirulent organism. Since there are numerous similarities between Bp and Bt, their differences in pathogenesis of host response and related mechanism are still undermined. In recent...

Counteraction of Trehalose on N, N-Dimethylformamide-Induced Candida rugosa Lipase Denaturation: Spectroscopic Insight and Molecular Dynamic Simulation

Candida rugosa lipase (CRL) has been widely used as a biocatalyst for non-aqueous synthesis in biotechnological applications, which, however, often suffers significant loss of activity in organic solvent. Experimental results show that trehalose could actively counteract the organic-solvent-induced protein denaturation, while the molecular mechanisms still don’t unclear. Herein...
