This study evaluated performance first commercial orthopedic metal artifact reduction function (O‐MAR) for therapy, investigated its clinical applications planning....
Abstract Background: Measurement of peptide/protein concentrations in biological samples for biomarker discovery commonly uses high-sensitivity mass spectrometers with a surface-processing procedure to concentrate the important peptides. These time-of-flight (TOF) instruments typically have low resolution and considerable electronic noise associated their detectors. The net result is unnecessary overlapping peaks, apparent jitter, difficulty distinguishing peaks from background noise. Many...
Improving the techniques for single-molecule conductance measurements is important progress of molecular electronics. In this report, a novel technique, which named molecular-junction mapping (MJM) demonstrated to be able simultaneously measure electronic single molecules and their corresponding conformations in an electrode gap. Measured conductances few model yield much narrower distribution as compared with results obtained using conventional break-junction indicating that better defined...
As immunotherapy has improved distant metastasis-free survival (DMFS) in Non-Small Cell Lung Cancer (NSCLC), isolated locoregional recurrences have increased. However, management of can be challenging. We report our institutional experience with definitive intent re-irradiation using Intensity Modulated Proton Therapy (IMPT).Retrospective cohort study recurrent or second primary NSCLC LS-SCLC treated IMPT. Kaplan-Meier method and log-rank test were used for time-to-event analyses.22 patients...
Abstract We have developed an automated procedure for aligning peaks in multiple TOF spectra that eliminates common timing errors and small variations spectrometer output. Our method incorporates high‐resolution peak detection, re‐binning, robust linear data fitting the time domain. This aligns label‐free (uncalibrated) to minimize variation each peak's location from one spectrum next, while maintaining a high number of degrees freedom. apply our replicate pooled‐serum laboratories increase...
A Compton imaging method for medical applications that includes new energy determination and data filtering techniques has been tested using several point sources with known emission lines. Using a prototype camera, distance-of-closest approach technique employed to determine the initial of incoming γs ensure reconstructed source position is within an acceptable distance from γ location. Further analysis done by implementing line technique, keeping only those interactions whose deposited in...
The through-space conductance of individual molecules is supposed to improve the macroscopic carrier movement, but most widely acclaimed channel just existed in sufficiently close π-π stacked benzene rings. As a breakthrough this primary cognition, additional conducting channels were confirmed exist non-strict face-to-face aligned thiophenes or phenyl-thiophene BDT derivatives for first time.
High-performing, real-time pose detection and tracking in will enable computers to develop a finer-grained more natural understanding of human behavior. However, the implementation estimation remains challenge. On one hand, performance semantic keypoint live video footage requires high computational resources large parameters, which limiting accuracy estimation. other some transformer-based models were proposed recently with outstanding much fewer parameters FLOPs. self-attention module...
To recommend imaging protocols and establish tolerance levels for microCT image quality assurance (QA) performed on conformal image-guided small animal irradiators. A fully automated QA software SAPA (small phantom analyzer) analysis of the commercial Shelley micro-CT MCTP 610 was developed, in which quantitative analyses CT number linearity, signal-to-noise ratio (SNR), uniformity noise, geometric accuracy, spatial resolution by means modulation transfer function (MTF), contrast were...
Cleaved, cation-derivatized Muscovite mica is utilized extensively in atomic force microscopy (AFM) imaging because of its flatness over large areas (millimeter cleavage planes with local root-mean-square roughness < 0.3 nm), ease preparation, and ability to adsorb charged biomolecules such as DNA (work by Hansma Laney, Guthold et al., McMaster al.). In particular, NiCl2 treatment has become a common method for controlling adsorption on substrates while retaining the mica's ultraflat surface...
