A new complete Calabi–Yau metric on \({\mathbb {C}}^3\)

Motivated by the study of collapsing Calabi–Yau 3-folds with a Lefschetz K3 fibration, we construct a complete Calabi–Yau metric on \({\mathbb {C}}^3\) with maximal volume growth, which in the appropriate scale is expected to model the collapsing metric near the nodal point. This new Calabi–Yau metric has singular tangent cone at infinity \({\mathbb {C}}^2/{\mathbb {Z}}_2 \times...

Simulation and Experimental Study on the Discontinuous Dynamic Impact on Unidirectional Confined Coal-Rock Damage

The deformation and the damage characteristics of coal and rock under different restraint static load and different impact velocity were studied with the FEM software LS-DYNA. Based on this, the influence of impact load on the damage of coal rock under one-dimensional constraint condition was studied by using the self-developed constrained pendulum impact dynamic loading test...

A novel one-pot three-step synthesis of 2-(1-Benzofuran-2-yl)quinoline-3-carboxylic acid derivatives

A facile and efficient one-pot three-step procedure for the preparation of 2-(1-benzofuran-2-yl)quinoline-3-carboxylic acid derivatives is described, featuring three different synthetic transformations, namely Williamson ether synthesis, hydrolysis of an ester group at the quinoline ring C-3 position, and intramolecular electrophilic cyclization reaction between the aldehyde...

Optical Rotation Detection for Atomic Spin Precession Using a Superluminescent Diode

A superluminescent diode (SLD) as an alternative of laser is used to detect optical rotation for atomic spin precession. A more uniform Gauss configuration without additional beam shaping and a relatively high power of the SLD have a potential for atomic magnetometers, which is demonstrated in theory and experiments. In addition, the robustness and compactness enable a more...

Lnc-PDZD7 contributes to stemness properties and chemosensitivity in hepatocellular carcinoma through EZH2-mediated ATOH8 transcriptional repression

Hepatocellular carcinoma (HCC) with stemness features are pivotal for tumorigenesis, chemoresistance, and progression. Long non-coding RNAs have been implicated in the regulation of HCC stemness features; however, their mechanisms remain largely unknown. Here, we found that Lnc-PDZD7 is a potential oncogene. We systematically analyzed the clinical significance and mechanism of...

Effects of oral activated charcoal on hyperphosphatemia and vascular calcification in Chinese patients with stage 3–4 chronic kidney disease

BackgroundThe relationship between oral activated charcoal (OAC) and hyperphosphatemia and vascular calcification is not completely clear. We observed and recorded the effects of OAC on hyperphosphatemia and vascular calcification in stage 3–4 chronic kidney disease (CKD).MethodsIn a randomized controlled study, we included 97 patients with stage 3–4 CKD. In the first phase of...

miR-10b suppresses cell invasion and metastasis through targeting HOXA3 regulated by FAK/YAP signaling pathway in clear-cell renal cell carcinoma

MicroRNAs have been related to tumor progression in diverse human cancers including clear-cell renal cell carcinoma (ccRCC). Previous study has suggested the important regulation function of miR-10b in ccRCC. However, the direct target of miR-10b in ccRCC and the related molecular mechanisms has not yet been revealed. miR-10b and HOXA3 was detected by qRT-PCR. MTT, colony...

Stiffness Calculation Model of Thread Connection Considering Friction Factors

In order to design a reasonable thread connection structure, it is necessary to understand the axial force distribution of threaded connections. For the application of bolted connection in mechanical design, it is necessary to estimate the stiffness of threaded connections. A calculation model for the distribution of axial force and stiffness considering the friction factor of...

Allopolyploidization facilitates gene flow and speciation among corn, Zea perennis and Tripsacum dactyloides

Main conclusionTripsacum dactyloides is closely related to Zea mays since Zea perennis and the MTP tri- species hybrid have four possible reproductive modes.Eastern gamagrass (Tripsacum dactyloides L.) and tetraploid perennial teosinte (Zea perennis) are well known to possess genes conferring resistance against biotic and abiotic stresses as well as adaptation to flood and...

Axial Micro-Strain Sensor Based on Resonance Demodulation Technology Via Dual-Mode CMECF

This paper firstly and experimentally demonstrates an in-fiber axial micro-strain sensing head, combined with a Mach-Zehnder interferometer (MZI) based on the concentric multilayer elliptical-core fiber (CMECF). This MZI with a high extinction ratio (about 15 dB) is successfully achieved with a CMECF-single mode fiber-CMECF (CSC) structure. The MZI sensor theory and the resonance...

A Method for Multicriteria Group Decision Making with Different Evaluation Criterion Sets

Multicriteria group decision making (MCGDM) with different evaluation criterion sets is a special kind of MCGDM problem, where criterion sets considered by multiple experts may be different, while research concerning this issue is still relatively scarce. The objective of this paper is to develop a method for MCGDM with different evaluation criterion sets. In the method...
