<title>Abstract</title> Current methods for evaluating biocarbon fixation efficiency (BCF), such as genome-scale metabolic models and life cycle assessment, lack consideration of reaction atom economy fail to connect genetic relationships with the process. To address these limitations, we introduced an atomic evaluation index centered on enzyme kinetics, named Economic Indicators Real Biological Carbon Fixation Atoms (EIRCBFA), proposed a machine learning-based model assess BCF at both...

The purpose of this pilot research was to investigate the differences using problem decomposition and recomposition among dyads engineering experts, seniors, freshmen. Fifty participants took part in study. Ten were design twenty All completed same challenge within an hour. entire process video audio recorded. After session, members participated a group interview. This study used protocol analysis as methodology. Video data transcribed, segmented, coded. Two coding systems including FBS...

Abstract The analysis and evaluation of student achievement is an important part teaching work school routine management. Scientifically analysing evaluating students’ academic achievements can not only enable teachers to accurately grasp the learning status, but also students understand their own situation, provide necessary for management improving teaching. In order evaluate situation comprehensively, objectively reasonably, this paper uses XGBoost algorithm classify performance based on...

It has been of increasing interest to decode the movements based on changes in hemoglobin concentration cerebral cortex that can be measured by functional near-infrared spectroscopy (fNIRS). Existing work were mainly focused motor imagery tasks for advantages fNIRS cognitive activation detection, and not well studied. This paper investigated feature extraction classification methods grip-force tasks. Two implemented compared. The first method took classic machine learning approach. Features...

Acrylate photoresists have gained considerable attention in recent years owing to their high resolution, sensitivity, and versality. In this work, a series of thermally stable copolymers are synthesized by introducing an isobornyl group, well characterized using Fourier transform infrared spectroscopy (FT-IR) nuclear magnetic resonance spectra (1H-NMR). The effects polymerization conditions on the molecular weight further influence lithography explored. By analyzing thermal properties,...

Dynamic contrast-enhanced 4-D MR renography has the potential for broad clinical applications, but suffers from respiratory motion that limits analysis and interpretation. Since each examination yields at least over 10 - 20 serial 3-D images of abdomen, manual registration is prohibitively labor-intensive. Besides in-plane translation, out-of-plane rotation are observed in image series. In this paper, a novel robust automated technique removing translation with sub-voxel accuracy dynamic...

Sodium polyacrylate as a kind of high absorbent resin, has an excellent water absorption performance, is low in price and isn’t corrosive. Compounds different particle sizes components were prepared using sodium chloride. They used the fog chamber to disperse warm respectively then. Experiments carried out investigate how size composition affect dissipation. Results follows are obtained: time light transmittance recovers 60% (t ) 85min when dissipates naturally; 30g whose average 30μm good...

ABSTRACT Polymeric membranes have been widely used in gas separation. However, the majority of these do not meet desired standards for separating H 2 and CO . The reason behind their subpar performance lies contradicting effects that exist within polymers, namely presence favorable diffusion selectivity but unfavorable solubility /CO A series thin‐film composite (TFC) were prepared via properly stacking polymeric nanoparticles as selective layers rubbery Pebax bonding buffering layers....

Sodium chloride (NaCl) is often used for warm mist elimination because of its easy deliquescence performance. In this paper, how dosages NaCl with two sizes affect fog was investigated. The changes light transmittance ( T ) and drops inside the chamber were monitored. Results indicate that particles smaller than 40μm work better 40-100μm, shortening time recovering to 60%( t 60% by 83.3% 25g. Reasons are they can decrease percentages small droplets, increase large droplets average drops,...

Multi-label unknown intent detection is a challenging task where each utterance may contain not only multiple known but also intents. To tackle this challenge, pioneers proposed to predict the number of first, then compare it with results matching decide whether contains intent(s). Though they have made remarkable progress on task, their method still suffers from two important issues: 1) It inadequate extract intents using encoding; 2) Optimizing sub-tasks (intent prediction and matching)...

The main problems of repair materials for concrete pavement are big shrinkage and weak bond etc. rapid material discussed in this paper is with compound early-strength admixture. Its compressive strength flexural (1d) up to 23.1MPa 3.74MPa respectively, which meets open traffic demand one day. Repair mixed alkali-proof glass fiber or polypropylene mesh were studied. Flexural interfacial increased, value reduced when was blended. results indicate that there a strong linear correlation between...

The two major volume visualization methods used in biomedical applications are Maximum Intensity Projection (MIP) and Volume Rendering (VR), both of which involve the process creating sets 2D projections from 3D images. We have developed a new method for very fast, high-quality images, based on fact that inverse this (transforming into image) is essentially equivalent to tomographic image reconstruction. This uses acquired by scanner, thereby obviating need computationally expensive steps...

Human visual-motor coordination is an important function of motor control, and requires interactions multiple brain regions muscles. It great significance to understand the coordination, specially for dynamic phase task planning execution. This study aimed establish effective connectivity analysis method explore mechanism. A hand-grip experiment with four conditions relaxation, vision only, grip visually-guided grip, was designed. High-density EEG surface EMG from extensor carpi radialis...

Coordination of lower limb joints during walking is an important indicator for clinical diagnosis and rehabilitation various nervous musculoskeletal system diseases. Despite the significant demand, coordination assessment has not been well explored due to limited availability needed measurement equipments analysis techniques. In this work, we propose a novel method quantify multiple taking videos gait as input. The locations are derived from using pose estimation algorithm. kinematic...

Patients with Parkinson's disease (PD) commonly have deficits in lower-limb movements. Freezing of gait (FOG), a type disturbance PD, is complex motor symptom exhibited as inability to generate an effective gait. The mechanism dysfunction especially FOG, remains be explored. To investigate the neural mechanisms related FOG we evaluated 39 subjects (13 PD patients 13 without and healthy subjects) based on electroencephalogram (EEG) signals while they performed pedaling task. We conducted...
