Photovoltaic (PV) power generation is one of the world's most promising options for carbon emission reduction. However, whether operation period solar parks can increase greenhouse gas (GHG) emissions in hosting natural ecosystems has not been fully considered. Here, we conducted a field experiment to compensate lack evaluation effects PV array deployment on GHG emissions. Our results show that arrays caused significant differences air microclimate, soil properties, and vegetation...
Forage culture is a common way to restore degraded grasslands and soil functions, in which the reconstruction of microbial community its relationship with extracellular enzyme activity (EEAs) can characterize recovery effects grasslands. However, impacts forage on interaction between microbes EEAs whether effect functions depends varying degradation statuses remain unclear. We conducted plantation dominant grass, Leymus chinensis, collected from severe, moderate, light, non-degradation...
The interaction between poisonous weeds and neighboring plants is complex. Poisonous frequently have a competitive advantage in the plants. Arbuscular mycorrhizal fungi (AMF) plant pathogenic (PPF) are closely related to interspecific relationships of However, role AMF PPF grasses remains unclear. Here, we designed pot experiment determine relationship Leymus chinensis Stellera chamaejasme regulation PPF. results showed that interactive effects L. S. significantly inhibited aboveground...
Objectives The purpose of this study is to evaluate the potential flattening filter free (FFF) mode a linear accelerator for patients with hippocampal avoidance whole-brain radiotherapy (HA-WBRT) by comparison flattened beams (FF) technique in application volumetric modulated arc therapy (VMAT) and intensity radiation (IMRT) using dosimetric radiobiological indexes based on volume hippocampus target. Methods 2 VMAT- IMRT- plans were optimized Eclipse planning system different delivery modes...
Abstract Purpose To investigate the interobserver variability (IOV) in target volume delineation of definitive radiotherapy for thoracic esophageal cancer (TEC) among centers China, and ultimately improve contouring consistency as much possible to lay foundation multi-center prospective studies. Methods Sixteen throughout China participated this study. In Phase 1, three suitable cases with upper, middle, lower TEC were chosen, participants asked contour a group gross tumor (GTV-T), nodal...
Background: Recently, an increasing number of cases with transformation from lung adenocarcinoma to small cell cancer (SCLC) have been identified, but few studies investigated the clinical, pathological as well molecular characteristics these cases. This study aimed summarize and analyze features.
Abstract The use of Monte Carlo treatment planning systems ( TPS ) in radiation therapy has increased the dosimetric accuracy VMAT sequences. However, this is compromised by not including couch into process. Therefore, impact on delivery output was determined, and two different models (uniform model A vs components B) were included tested Monaco to investigate which can better quantify influence dose. Relative attenuation measurements performed following procedures outlined TG ‐176 with...
Objective Whole lung irradiation (WLI) plays a crucial role in local control pediatric patients with metastases and improves patient survival. The intention of this research was to explore the advantage cardiac sparing between photons protons during WLI. We also propose new solution for proton techniques. Methods Eleven tumors pulmonary metastasis treated 12 Gy WLI (all received volumetric-modulated arc therapy (VMAT)) our institute 2010 2019 were retrospectively selected. Each replanned...
Multi-Object Tracking (MOT) aims to maintain stable and uninterrupted trajectories for each target. Most state-of-the-art approaches first detect objects in frame then implement data association between new detections existing tracks using motion models appearance similarities. Despite achieving satisfactory results, occlusion crowds can easily lead missing distorted detections, followed by false associations. In this paper, we revisit the classic tracker DeepSORT, enhancing its robustness...
We propose a direct detection scheme based on the asynchronous delay-tap plot (ADTP) and multi-task convolutional neural network (MT-CNN), which realizes joint monitoring of modulation formats (MFs) mode couplings (MCs) at intermediate nodes for division multiplexing (MDM) systems. The validity this is verified through simulation system with six kinds popular MFs, several MC intensities five different spatial modes. accuracies MFs MCs are more than 98.5% 98.8%, respectively, estimated...
Objective: The purpose of this study is to propose an alternative planning approach for VMAT using constant dose rate and gantry speed arc therapy(CDR‐CAS‐IMAT) implementation on conventional Linac Varian 23EX used IMRT as a benchmark evaluate the performance. Methods materials: Eighteen patients with thoracic esophageal carcinoma who were previously treated retrospectively planned CDR‐CAS‐IMAT plans. Dose prescription was set 60 Gy PTVs in 30 fractions. objectives OAR corresponding compared...
Volumetric-modulated arc therapy(VMAT), as novel technology not only can produce similar or better dose distributions, but also reduce treatment time and the monitor units (MU). However, VMAT be implement-ed on new generation accelerators such Varian Rap-idArc Elekta Synergy, which prevents most existing linacs from delivering in VMAT. The purpose of this study is to investigate using constant rate IMAT conventional linear accelrator, by comparing with IMRT evaluate performance thoracic...
Objective To investigate the therapeutic effects, adverse and patterns of failure elective irradiation lymphatic drainage area (extended-field) involved-field in three-dimensional radiotherapy (3DRT) patients with esophageal cancer via a Meta-analysis. Methods The databases Wanfang Data, CNKI, VIP, CBM, PubMed, Embase, Cochrane Library were searched to collect controlled clinical trials on extended-field 3DRT cancer. Stata 11.0 was used for data analysis. The odds ratio (OR) 95%...
Objective To evaluate the long-term efficacy and related prognostic factors of cervical upper esophageal carcinoma treated with intensity-modulated radiotherapy (IMRT). Methods From January 2006 to August 2012, 159 patients squamous cell IMRT were analyzed retrospectively.
