Model based heterogeneous data collaboration is important in the integrated design and manufacturing technology. In this work, we propose a systematic method of collaborative design method for heterogeneous data sources. In our method, we use the Open Model Based Engineering Environment (OpenMBEE) to study. In our work, we setup environment and construct the integrated multi-tools achieving consistency design, and then we successfully design and implement a reasonable scheme to parameterize the model in requirement analysis and store the extracted parameters in Model Management System (MMS) for transporting to the visualization tool for further simulation. We integrate the mathematical analysis tools of MATLAB, and successfully design the interface in the tool integration, and realize the model consistency in the problem of integrating multiple tools in the design based on model center. The effectiveness of the proposed integration strategies is verified by some practical instances. That is verified that our provided study can an effective design idea for complex production.

Traditional drug delivery techniques often have drawbacks such inadequate bioavailability, quick clearance, and non-specific targeting, which may result in unfavorable side effects. Hybrid nanocarriers composed of nanoclay have the potential to be a viable solution to these problems. The goal of this work was to design a biocompatible hybrid nanocarrier that would release curcumin under regulated conditions to specific locations, especially cancer cells. FTIR, XRD, and FESEM were used to effectively construct and evaluate our polyvinyl pyrrolidone/polyethylene glycol/montmorillonite (PVP/PEG/MMT) hybrid hydrogels, verifying their synthesis and intended features. Zeta potential and DLS studies showed a suitable size distribution (∼300 nm) and high stability. The curcumin encapsulation efficiency and release profile were assessed using the use of UV spectrophotometry and the dialysis bag technique. The findings showed a gradual and continuous release that was highly impacted by the acidic environment (which mimicked the characteristics of cancer cells), suggesting pH-responsive activity. The MTT test was used in vitro cytotoxicity experiments to show that curcumin-loaded nanocarriers were more effective against MCF-7 cancer cells than curcumin in solution. Increased rates of necrosis and apoptosis in cancer cells treated with the nanocarrier formulation were further validated by flowcytometry. According to these results, PVP/PEG/MMT hybrid hydrogels have a lot of potential as a cutting-edge drug delivery strategy for curcumin. They may be able to overcome some of the drawbacks of traditional techniques and improve the effectiveness of treatment against cancer cells. © 2024 The Authors

We propose a theoretical model to elucidate intermolecular electrostatic interactions between a virus and a substrate. Our model treats the virus as a homogeneous particle having surface charge and the polymer fiber of the respirator as a charged plane. Electric potentials surrounding the virus and fiber are influenced by the surface charge distribution of the virus. We use Poisson-Boltzmann equations to calculate electric potentials. Then, Derjaguin’s approximation and a linear superposition of the potential function are extended to determine the electrostatic force. In this work, we apply this model for coronavirus or SARS-CoV-2 case and numerical results quantitatively agree with prior simulation. We find that the influence of fiber’s potential on the surface charge of the virus is important and is considered in interaction calculations to obtain better accuracy. The electrostatic interaction significantly decays with increasing separation distance, and this curve becomes steeper when adding more salt. Although the interaction force increases with heating, one can observe the repulsive-attractive transition when the environment is acidic. Copyright © 2021, The Authors. All rights reserved.

While first order perturbation theory is routinely used in quantum Monte Carlo (QMC) calculations, higher-order terms present significant numerical challenges. We present a new approach for computing perturbative corrections in projection QMC calculations. We demonstrate the method by computing nuclear ground state energies up to second order for a realistic chiral interaction. We calculate the binding energies of several light nuclei up to O16 by expanding the Hamiltonian around the Wigner SU(4) limit and find good agreement with data. In contrast to the natural ordering of the perturbative series, we find remarkably large second-order energy corrections. This occurs because the perturbing interactions break the symmetries of the unperturbed Hamiltonian. Our method is free from the sign problem and can be applied to QMC calculations for many-body systems in nuclear physics, condensed matter physics, ultracold atoms, and quantum chemistry.

We discuss recent lattice data for the Tcc(3875)+ state to stress, for the first time, a potentially strong impact of left-hand cuts from the one-pion exchange on the pole extraction for near-threshold exotic states. In particular, if the left-hand cut is located close to the two-particle threshold, which happens naturally in the DD∗ system for the pion mass exceeding its physical value, the effective-range expansion is valid only in a very limited energy range up to the cut and as such is of little use to reliably extract the poles. Then, an accurate extraction of the pole locations requires the one-pion exchange to be implemented explicitly into the scattering amplitudes. Our findings are general and potentially relevant for a wide class of hadronic near-threshold states. © 2023, CC BY.

The β-delayed two-proton (β2p) decay of S27 was studied using a state-of-the-art silicon array and Clover-type HPGe detectors. An energy peak at 6372(15) keV with a branching ratio of 2.4(5)% in the decay-energy spectrum was identified as a two-proton transition via the isobaric-analog state in P27 to the ground state of Al25 in the β decay of S27. Two-proton angular correlations were measured by the silicon array to study the mechanism of two-proton emission. Based on experimental results and Monte Carlo simulations, it was found that the main mechanism for the emission of β2p by S27 is of sequential nature.

A whole-annulus unsteady numerical simulation is carried out to investigate the mechanism of the rotating stall in a 1.5-stage low-speed axial-compressor. By comparing the experimental and numerical results, the numerical results are validated. The numerical simulation captures the most features of the rotating stall of the 1.5-stage compressor observed from the experimental results. The unsteady bubble-like breakdown appears in the tip leakage vortex at the near stall condition. With the compressor throttling, the modal wave appears, increases in intensity and induces the part of the breakdown-vortex flow spilled over the adjacent blade leading-edge unsteadily, which form a spike. Consequently, the spikes emerge around the compressor annulus at the same time and the intensity and size of the spikes is increased rapidly during the inception period. At last, the spikes are merged into a large stall cell, which propagates around the annulus with 30% rotor speed. © Open Archives of the 16th International Symposium on Transport Phenomena and Dynamics of Rotating Machinery, ISROMAC 2016.

Malicious code is characterized by a large number of types, rapid increase in number, continuous update of transmission routes, and continuous enhancement of back analysis and back detection methods. Therefore, how to effectively detect and analyze malicious code has been a problem of great concern. This paper studies the features of binary file and disassembly file of malicious code, introduces the concept of information gain, and proposes a method to construct the multi-dimensional characteristic graph of malicious code. Finally, the convolutional neural network is used to classify the multi-dimensional feature graph of malicious code, which provides a new idea for the feature extraction of malicious code.
