Abstract Background The biological phenotype of tumours evolves during neoadjuvant chemotherapy (NAC). Accurate prediction pathological complete response (pCR) to NAC in the early-stage or posttreatment can optimize treatment strategies improve breast-conserving rate. This study aimed develop and validate an autosegmentation-based serial ultrasonography assessment system (SUAS) that incorporated ultrasonographic features throughout breast cancer predict pCR. Methods A total 801 patients with...
High-resolution solar absorption spectra were continuously collected by a ground-based Fourier transform infrared (FTIR) spectrometer to retrieve the total column of carbon monoxide (CO), hydrogen cyanide (HCN), ethane (C 2 H 6 ), acetylene and formaldehyde (H CO). The time series variation characteristics these gases analyzed. biomass combustion process is identified using correlations between monthly mean deviations HCN, C , CO versus satellite fire point data. months with high correlation...
In the realm of defect detection, there are distinctions in emphasis placed on features between classification and localization components task. The task emphasizes semantic information from global context, while prioritizes spatial details such as edges. Directly coupling these two subtask can hinder model convergence degrade performance appearance detection power adapters. To address this issue, we proposed Task-feature Decoupled Feature Pyramid Network (TDFPN) module based YOLOv8n. This...
High-resolution solar absorption spectra, observed by ground-based Fourier Transform Infrared spectroscopy (FTIR), are used to retrieve vertical profiles and partial or total column concentrations of many trace gases. In this study, we present the tropospheric CO 2 columns retrieved mid-infrared spectra over Hefei, China. To reduce influence stratospheric cross-dependencies on , an a posteriori optimization method based simple matrix multiplication is correct columns. The corrected time...
Preoperative assessment of lymphovascular invasion (LVI) in invasive breast cancer (IBC) is high clinical relevance for treatment decision-making and prognosis.To investigate the associations preoperative magnetic resonance imaging (MRI) characteristics with LVI disease-free survival (DFS) by using machine learning methods patients IBC.Retrospective.Five hundred seventy-five women (range: 24-79 years) IBC who underwent MRI examinations at two hospitals, divided into training (N = 386)...
Understanding the distribution of atmospheric water vapor (H2O) is crucial for global warming studies and climate change mitigation. In this study, we retrieved ground layer, tropospheric total columns H2O using ground-based high-resolution Fourier transform infrared spectrometry (FTIR). The are obtained from near-infrared (NIR) mid-infrared (MIR) spectra, layer MIR spectrum. NIR have a good consistency (R = 0.989). Additionally, similar seasonal variation to but higher amplitude. close in...
As an important irritant trace gas in the atmosphere, ammonia (NH3) significantly impacts human health and environment. Bottom-up emission inventories are widely used to estimate emissions their geographical distributions over China. However, high uncertainties still associated with due inaccurate factors used. The Differential Evolution (DE) algorithm is a population-based stochastic optimization solve complicated problems. We quantify NH3 lifetime from Infrared Atmospheric Sounding...
Vertical profiles and stratospheric HNO3 HCl columns are retrieved by ground-based high resolution Fourier transform infrared spectroscopy (FTIR) remote sensing measurements at the Hefei site in China. The time series of from January 2017 to December 2019 showed similar annual variation trends, with an annually decreasing rate (−9.45 ± 1.20)% yr−1 (−7.04 0.81)% for HCl, respectively. seasonal amplitudes 2.67 × 1015 molec cm−2 4.76 1014 respectively, both reaching their maximum March minimum...
Abstract. Synthetic halogenated organic chlorofluorocarbons (CFCs) play an important role in stratospheric ozone depletion and contribute significantly to the greenhouse effect. In this work, mid-infrared solar spectra measured by ground-based high-resolution Fourier transform infrared spectroscopy (FTIR) were used retrieve atmospheric CFC-11 (CCl3F) CFC-12 (CCl2F2) at Hefei, China. The columns observed from January 2017 December 2020 September 2015 show a similar annual decreasing trend...
We utilize the tropospheric NO 2 columns derived from observations of Ozone Monitoring Instrument (OMI) onboard AURA to analyze spatial distributions and temporal trends in Wanjiang City Belt (WCB) China 2005 2016. The aim this study is assess effect industrial transfer policy on air quality WCB. Firstly, we used surface situ concentrations compare with OMI-retrieved order verify accuracy satellite data over WCB area. Although it difficult two datasets directly, comparison results prove...
Doping at the Sr site in ${\mathrm{Sr}}_{2}{\mathrm{IrO}}_{4}$ is predicted to be a possible route high-temperature superconductivity, which has not yet been experimentally achieved. We have made comprehensive investigation on interplay among Ir-O-Ir bond angle, carrier density, and magnetic transport properties of rare-earth-doped by choosing Pr Ce as dopants. find that compared with doping, doping introduces more effective charge carriers into matrix, leading rapid suppression its...
Abstract Sr 2 IrO 4 has been shown to exhibit a novel J eff = 1 / Mott spin–orbit insulating state with antiferromagnetic ordering. In the present investigation, effects of Pr substitution at Sr-site on structural, magnetic and electrical properties are studied in . Pr-doped samples still retain behavior, but increase doping concentration, resistivity decreases. The show that long-range order is collapsed when content increases up 20%, which may results from competition between AFM (Ir 5 d...
