To propose a new method for optimizing radiotherapy planning lung cancer by incorporating prognostic models that take into account individual patient information and assess the feasibility of treatment optimization directly guided minimizing predicted risk. A mixed fluence map objective was constructed, outcome-based physical dose constraints. The function constructed as an equally weighted summation prediction local control failure, radiation-induced cardiac toxicity, radiation pneumonitis...

Rapid urbanization in China has strengthened the connection and cooperation among cities also led urban residents to be more vulnerable adverse environmental conditions. Vulnerability research been an important foundation risk management. To make safe resilient, it is necessary integrate into a vulnerability assessment. Therefore, this paper proposed new conceptual framework for social assessment based on network theory, where dimension of (connectivity) was added framework. Using attribute...

Many frequent and severe air pollution incidents have emerged across the vast parts of China recently. The identification factors mapping social vulnerability has become extremely necessary for environmental management sustainable development. However, studies associating with remain sparse. With reference to research achievements vulnerability, this study made a new trial regarding assessment pollution. projection pursuit cluster (PPC) model, top three contributing index (SVI) were...

This research offers a new framework for assessing social vulnerability to climate change. A assessment trial was carried out Chinese coastal cities at the county level. First, 10 factors having most influence on were identified. They are “House with no lavatory”, bath facilities”, “Employees in primary industry”, “Houses tap water”, “GDP sector”, “Children”, kitchen”, “Rate of natural increase (RNI), management and “Highly educated”. Second, indexes vulnerability, exposure, sensitivity,...

At-home water filters for drinking are used by over 100 million Americans. These successful at removing heavy metals from water; however, when present, can reach saturation quickly. This currently requires a full filter replacement; treating and regenerating (re-activating) the not recommended manufacturers. Here, we present sustainable graphene-based that be regenerated treatment with hot (80 °C) or vinegar (mild acid). The has multiple desirable properties metal adsorption, including high...

In this study, a millimetre‐wave slotted array antenna based on double‐layer substrate integrated waveguide (SIW) is proposed. The radiating and feeding network are arranged different layers with normal printed circuit board process. design procedure of elements parameters extraction introduced. A broadband T‐junction tilted coupling slots used for power division in network. right‐angle transition between SIW standard rectangular WR28 designed the bottom metallic plate measurement. An 8 ×...

China is vulnerable to climate change. Developing the ability assess social vulnerability and inequality amid change will be imperative ensure that adjustment policies can developed for various groups build resilient livelihoods in China. This paper examines through a joint analysis of urban agglomerations. Based on conceptual framework from network perspective, index individual cities quantified with projection pursuit cluster model, networks calculated Baidu Index, an measured by Theil...

Wald’s protocol is the most widely accepted to assess pan-sharpening algorithms. In particular, synthesis property—which usually validated on a reduced scale—is thought be necessary and sufficient condition of success image fusion. Usually, property evaluated at resolution scale take original multispectral (MS) as reference; thus, degradation method that employed produce images crucial. past decade, standard has been decimate low-pass-filtered where filter designed match modulation transfer...

This paper explored a new approach regarding social vulnerability to climate change, and measured in three parts: (1) choosing relevant indicators of change; (2) based on the Hazard Vulnerability Similarity Index (HVSI), our method provided procedure choose referenced community objectively; (3) ranked vulnerability, exposure, sensitivity, adaptability according profiles similarity matrix specific attributes communities. was applied case study Yangtze River Delta (YRD) region findings...

Abstract Background Current intensity-modulated radiation therapy (IMRT) treatment planning is still a manual and time/resource consuming task, knowledge-based methods with appropriate predictions have been shown to enhance the plan quality consistency improve efficiency. This study aims develop novel prediction framework simultaneously predict dose distribution fluence for nasopharyngeal carcinoma treated IMRT, predicted information can be used as objectives initial solution an automatic...

A two‐layer remote sensing model for estimating daily evapotranspiration over a large area was developed. The followed an energy balance approach, where is estimated as residual when net radiation, sensible heat flux and ground are known. accuracy of the outputs determined using harmonized surface conditions derived from measurements stations. An accurate agreement (r 2 = 0.844, n 48) between estimates ground‐based measurement obtained.

The sources and variation trend of ambient air pollutants, the duration pollution process conditions for decontamination were analyzed in this essay based on pollutants data, PM2.5 source analysis data meteorological factors Nanchong City during 2014 to 2019. results indicated that concentrated discharge fireworks New Year’s Eve was main reason sharp deterioration quality. PM10 concentrations increased significantly after set off, peak value appeared at about 02:00 Lunar Day, but PM2.5/PM10...

A remote sensing approach towards modelling the land cover pattern for controlling local soil erosion based on universal loss equation (USLE) was developed. The used to analyse possible impact of changes ecological security. Then, optimization aiming at reduction taken. Results show that this method can be applied security management.

Picoxystrobin is a systemic fungicide widely used on potato, citrus fruit, and Dendrobium officinale. To provide information for the risk assessment of citrus, officinale, field experiments combined with QuEChERS HPLC-MS/MS were performed to detect picoxystrobin. had good linearity (R2 > 0.99), average recovery rate was 75 − 102%, relative standard deviation 1 11%. utilized as test agent in experiments, samples evaluated analyzed at various times after final application utilizing random...

Large depth of field and uniform axial intensity distributions are important in many practical applications. Lots optical elements have been proposed for this end, such as full-aperture logarithmic axicons (LAs), annular-aperture LAs apodized LAs. In millimeter/submillimeter (mm/submm) range, the refractive-diffractive behaviors (including transverse longitudinal distributions) behind these illuminated by a plane wave calculated rigorous electromagnetic analysis method our paper.
