Force Feedback Method for Statically Indeterminate Steel Structure Construction Based on Staged Temperature Measurement.

Structural design usually adopts uniform temperature action. However, during the actual construction of the structure, the temperature field acting on the structure is inhomogeneous. Therefore, the simulation of the construction of statically indeterminate steel structures considering only the uniform temperature field cannot truly reflect the temperature action after structural molding and the evolution of the stress performance of the temporary stress system of structural construction.

Gemcitabine-Loaded Microbeads for Transarterial Chemoembolization of Rabbit Renal Tumor Monitored by F-FDG Positron Emission Tomography/X-Ray Computed Tomography Imaging.

Background/objectives: The purpose of this study was to develop the gemcitabine-loaded drug-eluting beads (G-DEBs) for transarterial chemoembolization (TACE) in rabbit renal tumors and to evaluate their antitumor effect using 2-deoxy-2-[(18)F]fluoro-D-glucose positron emission tomography/X-ray computed tomography (F-FDG PET/CT).

Methods: DEBs were prepared by polyvinyl alcohol-based macromer crosslinked with -acryl tyrosine and ,'-methylenebis(acrylamide). Gemcitabine was loaded through ion change to obtain G-DEBs.

Genome-Wide Identification and Expression Analysis of Gene Family Members in Seashore Paspalum Under Salt Stress.

The gene family plays a crucial role in plant growth, development, and responses to biotic and abiotic stresses. , a warm-season turfgrass with exceptional salt tolerance, can be irrigated with seawater. However, the gene family in seashore paspalum remains poorly understood.

Utilizing Headspace-Gas Chromatography-Ion Mobility Spectroscopy Technology to Establish the Volatile Chemical Component Fingerprint Profiles of Processed by Different Preparation Methods and to Perform Differential Analysis of Their Components.

In order to characterize the volatile chemical components of processed by different Traditional Chinese Medicine Processing methods and establish fingerprint profiles, headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) technology was employed to detect, identify, and analyze processed by five different methods. Fingerprint profiles of volatile chemical components of processed by different methods were established; a total of 85 different volatile organic compounds (VOCs) were detected in the experiment, including esters, alcohols, ketones, aldehydes, terpenes, olefinic compounds, nitrogen compounds, lactones, pyrazines, sulfur compounds, thiophenes, acid, and thiazoles. Principal component analysis (PCA), Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA), and Pearson correlation analysis methods were used to cluster and analyze the detected chemical substances and their contents.

Chemometric Classification and Bioactivity Correlation of Black Instant Coffee and Coffee Bean Extract by Chlorogenic Acid Profiling.

Chlorogenic acids (CGAs) play a key role in defining the quality and functionality of coffee products. CGA fingerprints of black instant coffee (BIC) and coffee bean extract (CBE) were profiled using ultra-performance liquid chromatography-mass spectrometry and analyzed by chemometrics. A total of 25 CGAs were identified.
