Abstract

Finding hot topics in scholarly fields can help researchers to keep up with the latest concepts, trends, and inventions in their field of interest. Due to the rarity of complete large-scale scholarly data, earlier studies target this problem based on manual topic extraction from a limited number of domains, with their focus solely on a single feature such as coauthorship, citation relations, and etc. Given the compromised effectiveness of such predictions, in this paper we use a real scholarly dataset from Microsoft Academic Graph, which provides more than 12000 topics in the field of Computer Science (CS), including 1200 venues, 14.4 million authors, 30 million papers and their citation relations over the period of 1950 till now. Aiming to find the topics that will trend in CS area, we innovatively formalize a hot topic prediction problem where, with joint consideration of both inter- and intra-topical influence, 17 different scientific features are extracted for comprehensive description of topic status. By leveraging all those 17 features, we observe good accuracy of topic scale forecasting after 5 and 10 years with R2 values of 0.9893 and 0.9646, respectively. Interestingly, our prediction suggests that the maximum value matters in finding hot topics in scholarly fields, primarily from three aspects: (1) the maximum value of each factor, such as authors' maximum h-index and largest citation number, provides three times the amount of information than the average value in prediction; (2) the mutual influence between the most correlated topics serve as the most telling factor in long-term topic trend prediction, interpreting that those currently exhibiting the maximum growth rates will drive the correlated topics to be hot in the future; (3) we predict in the next 5 years the top 100 fastest growing (maximum growth rate) topics that will potentially get the major attention in CS area., Comment: 10 pages

Abstract

This study aims to review the biomarkers of depression discovered by proteomic techniques to guide the identification of specific biomarkers for depression. Depression is a common psychological disease， and its diagnosis and efficacy evaluation rely on subjective clinical evaluation， lacking objective diagnostic tools. Proteomics is the primary method to discover and verify biomarkers. This study reviews proteomic biomarkers in brain tissue， cerebrospinal fluid and blood of patients with depression， as well as the latest strategies for screening biomarkers of depression.

6. Optimizing Printhead Design for Enhanced Temperature Control in Extrusion-Based Bioprinting.

Author

Guo, Ruhan and Tang, Wencheng

Abstract

This study addresses critical challenges in the field of tissue engineering, specifically in the optimization of bioprinting technologies for the construction of complex, multicellular tissues. By utilizing a homemade piston-driven extrusion-based bioprinting (EBB) printhead, we performed detailed thermal and flow analyses to investigate the effects of temperature variations on the extrusion process of temperature-sensitive gelatin-alginate bioink. Through finite element method (FEM) simulations, we explored the temperature distribution within the printhead and its impact on bioink properties, such as viscosity, pressure, and shear stress. Key findings reveal significant temperature gradients from the printhead barrel to the nozzle tip, influencing bioink extrusion and filament morphology. This study further introduces an innovative hardware optimization with thermal insulators, designed to mitigate heat loss at the nozzle tip and ensure uniform temperature distribution. Both simulation and empirical printing experiments confirm the efficacy of thermal insulators in enhancing bioprinting fidelity and efficiency. This research contributes to the advancement of bioprinting technology by optimizing printhead design, with implications for improving the quality of bioprinted tissues and organs.

35. The dynamic investigation of intrinsic vibration characteristics of a stranding machine by the finite element method

Abstract

In response to the design problems of violent vibration and noise when a stranding machine is running at high speed, this project completed a motion simulation and vibration analysis based on the prototype FB-650C-2 bow-type stranding machine produced by Fuchuan Mechanical and Electrical Technology Co. The modal analysis was carried out in ANSYS to obtain the first eight orders of inherent frequencies and vibration patterns, combined with excitation force analysis to verify whether the rotating parts could avoid the resonant frequency when operating. Harmonic response analysis was carried out based on the modal state to calculate the steady-state forced vibration of the structure, and the variation curve of response value (usual deformation) with frequency and the cloud diagrams of stress distribution of each component at the rotation frequency were obtained. Suggestions for improving vibration and reducing noise were made based on the experimental and analytical results.

Abstract

In order to investigate the vibration characteristic of ball screws,an end- block type ball screw is selected as an example,a vibration model of the ball screw which is capable of capturing the vibration in drive dynamics as the nut moves along the screw is established. Based on the stiffness and damping stiffness which considering the nut raceway and screw raceway contact interface lubrication,hybrid model of flexible ball screw is established. Then,the vibration data are collected and analyzed on the test bench of ball screw vibration and noise. Finally,the effect of varying the screw rotational speed and nut position on the ball screw vibration are investigated numerically and experimentally. The analysis indicates that the movable nut plays the role of supporting spring in the ball screw feed drive,therefore,the vibration of the ball screw is very sensitive to nut position changes.
