Impact of metformin on the therapeutic effect of radiotherapy

Objective: To explore the effect of metformin on therapeutic outcomes in cancer patients undergoing radiotherapy. Methods: A literature search of the electronic databases was conducted to retrieve articles that investigated the effect of metformin on radiotherapy. Timeframe of electronic search ranged from the inception of each database to May 2020. These databases include PubMed, Embase and Scopus. Results: From an initial search of 142 articles, and after the removal of duplicates as well as applying the inclusion and the exclusion criteria, 20 articles were finally included in this systematic review. Results from the reviewed clinical studies showed promising therapeutic effect of the combination of metformin with radiotherapy. Metformin has promising therapeutic effects as an adjuvant with radiotherapy. Conclusions: The use of metformin as an adjuvant with radiotherapy should be treated with caution, as further studies investigating its optimal dose as well as molecular mechanisms are still needed.
Engineering photo-controllable fragrance release with flash nanoprecipitation

Controllable profragrance nanoparticles are in great demand for long-lasting scent in flavor and fragrance industries. However, the practical applications of controllable fragrance release are limited by the non-tunable size, structural heterogeneity and poor reproducibility. Herein, a coumarin-derived phototrigger (CM-OH) is covalently conjugated with alcohol fragrances to obtain the corresponding profragrances (CM-R) which enable to release fragrances under the light controlling conditions. Furthermore, we introduce a new engineering strategy to construct fine tunable and highly uniform profragrance nanoparticles with flash nanoprecipitation (FNP) technology, which features commercial available amphiphilic pluronic F127 polymers by encapsulation of photoactivatable profragrances CM-R in hydrophobic cores to enhance the long-lasting photo-controllable fragrance release. With the assistance of FNP technology, amphiphilic pluronic polymer and profragrances CM-R in organic solution are instantaneously mixed and subsequently precipitated in the multi-inlet vortex mixer (MIVM), thus obtaining the pluronic F127-encapsulated profragrance nanoparticles with good homogeneity. Compared to the traditional thermodynamic encapsulation method, the novel kinetic FNP technology can not only tune the size of profragrance nanoparticles with narrow distribution, but also distinctly improve the batch-to-batch reproducibility, which affords an alternative method for scale-up preparation of amphiphilic profragrance nanoparticles in precisely controllable fragrance delivery system.
Recent applications of ionic liquids in quasi-solid-state lithium metal batteries

Quasi-solid-state lithium metal batteries are considered as one of the most promising energy storage devices, and the application of ionic liquids (ILs) as a new generation of functionalized electrolyte components in lithium metal batteries has become one of the research focuses. In this review, the very recent research work related to using ILs to develop quasi-solid-state electrolytes and their influences on the performances of quasi-solid-state lithium metal batteries were surveyed and summarized, suggesting that the introduction of ILs can improve the ionic conductivity, broaden the electrochemical stability window, and enhance the electrochemical stability of the selected electrolytes. Moreover, using ILs to prepare high-performance electrodes with unique microstructures and uniform distribution of fillers were also introduced. The composite quasi-solid-state electrolytes were suggested as the mainstream of electrolytes in the future due to the combination of the advantages of inorganic and polymer quasi-solid-state electrolytes, and their development challenges in high energy and high safety quasisolid-state lithium metal batteries were also discussed.
Production of biomass-derived monomers through catalytic conversion of furfural and hydroxymethylfurfural

The synthesis of biomass-derived monomers has received great attention in recent years, motivated by the depletion of fossil fuels and environmental issues. Moreover, the intrinsic functionality within the biomass or biomass-derived chemicals has great potential to produce new types of monomers containing multiple acid or alcohol groups, thereby leading to materials with novel properties. Given their versatile functional groups and easy production from cellulose/hemicellulose, furfural and hydroxymethylfurfural were regarded as very important biomass-derived platform chemicals through which multiple monomers can be produced via heterogeneous catalysis. In the current review, recent development in heterogeneous catalysis for the production of 6 bio-based monomers, furfuryl alcohol, 2,5-bis(hydroxymethyl)furan, 2,5-bis-(hydroxymethyl)tetrahydrofuran, 1,5-pentanediol, 1,6-hexanediol, and 2,5-furandicarboxylic acid, from furfural and hydroxymethylfurfural is reviewed and summarized. The major challenge is how to efficiently and selectively convert specific functional group(s) in furfural and hydroxymethylfurfural during the production of these monomers. Additionally, catalyst stability issues need to be addressed due to necessity of using hot water as reaction medium and high tendency of carbonaceous deposit formation on catalyst surface. The current review mainly focuses on efforts of catalytic site design and modification, including selection of metal/support, use of synergy between metal and support, tuning metal size, use of inverse catalysts, adding catalytic promoters, constructing bimetallic sites, etc., to realize efficient, selective and stable production of bio-based monomers from furfural and hydroxymethylfurfural.
Individual and local scale interactions and adaptations to wind energy development: A case study of Oklahoma, USA

Wind energy development receives broad support but is often opposed at the local level due to nuisance concerns and uncertainties about how it affects the landowners living due to the turbines and the broader community. Local opposition to wind energy development can be a powerful force slowing or even ending its implementation in a given region. Oklahoma, USA is currently ranked as 4 th in the United States in current wind energy production and has seen significant pushback from some local communities as a renewable energy resource. Previous studies have examined wind energy development's impact on rural education income, and property values of different communities in Oklahoma. However, funding information on how wind energy development affects the individuals living alongside the turbines are limited. Using fifteen interviews with landowners, site-managers, community representatives, and pro-wind non-profit organization representatives, this study finds that individuals who live in proximity to wind energy development, particularly those involved in the agricultural industry, have created novel and unique uses for wind farm infrastructure. It also finds that local perceptions of wind energy production are mostly positive and provides increased knowledge of how wind energy development affects the individuals and communities that are hosting the turbines and related infrastructure.
Prediction-Adaptation-Resilience (PAR) approach-A new pathway towards future resilience and sustainable development of urban landscape

Urban land-use planning, especially in the peripheral region, has become an issue in contemporary urban studies. Simultaneously, urban resilience is very indispensable for future urban land use planning and management. Therefore, consistent urban proliferation can be coped through Prediction-Adaptation-Resilience (PAR), to accomplish future urban land use and sustainable development of any growing up urban areas worldwide. Therefore,different dynamic simulation models, e.g. Cellular automata-Markov model, artificial neural network, are used to project and predict any urban areas' spatial growth. Then, the adaptation strategies are taken to assess the urban land use transformation in the past and present context. Those strategies help to strengthen urban land use planning using an integrated supply and demand chain. Finally, this study checks the resilience of how much it will be threatened or saved for future sustainable urban developmental goals and urban resilience. Therefore,it is important to establish a conceptual framework to achieve Sustainable Development Goals (SDGs) based on principles of the PAR approach. Advocating the on-going adaptation of sustainability, resilience, and rapid urban transformation in the developing cities requires clear and explicit definitions that are embedded with the recent and particular context. Thus, government and policy makers should draw their attention to make proper urban landscape planning and adaptation strategies for the future urban expansion in a holistic way by maintaining appropriate urban resilience.
The spatial coupling characteristics between the construction of Qingzang National Park Cluster and the sustainable development of local communities

The development of Qingzang national park cluster is part of China's efforts to establish a major ecological civilization project in the Qingzang Plateau, in line with global sustainable development goals. Based on preliminary scientific investigation and research in the Qingzang Plateau, the construction of the park cluster will include 21 national parks. To mitigate the conflict between conservation of the national park cluster and the development of local communities, this study proposes an analysis framework to identify the spatial coupling features between the national park cluster and sustainable development of communities. Four elements were selected to construct the analysis framework, including natural conditions, geographic location, cultural background, and national policies. This framework was applied to the 457 township communities within the 21 national parks. Results show the weak influence of the construction of the national park cluster for approximately 304 township communities, without significant spatial coupling traits, while the remaining 153 communities demonstrated significant spatial coupling features. These latter townships had developed four types of spatial coupling with national parks, including eco-migrants, transportation hubs, characteristic cultures, and border development, which account for 17.4%, 35.3%, 19.8%, and 27.5% of the 153 townships respectively. A composite type with more than one spatial coupling feature was also found for 14 communities within the 153 townships. This provides a reference for policy making towards four major types of interactive modes between townships and the national park construction for the sustainable development of Qingzang Plateau.
Ultrasound Assessment of Placenta Accreta Spectrum (PAS), Clinical Management of PAS in Our Society IS-PAS: Minutes of 2020 Online International Workshop on PAS

Placenta accreta spectrum (PAS) of higher grade is a severe obstetric complication. Without prenatal detection, attempting to remove the placenta tissue after baby delivery as usual may cause massive bleeding and could end in unplanned cesarean hysterectomy, thus threatening primarily maternal but also fetal outcome. Prenatal screening and detection by ultrasound assessment is a useful way to improve outcome of these rare cases in preparing optimal conditions for the delivery.
Point Cloud Classification and Accuracy Analysis Based on Feature Fusion

A method for land-cover classification was proposed based on the fusion of features generated from waveform data and point cloud respectively.It aims to partially overcome the ineffectiveness of many traditional classifiers caused by the fact that point cloud is lacking spectral information.The whole flowchart of the method is as follows:Firstly,Gaussian decomposition was applied to fit an echo full-waveform.The parameters associated with the Gaussian function were optimized by LM (Levenberg- Marquard) algorithm.Six and thirteen features were generated to describe the waveform characteristics and the local geometry of point cloud,respectively.Secondly,a random forest was selected as the classifier to which the generated features were input.Relief-F was used to rank the weights of all the features generated.Finally,features were input to the classifier one by one according to the weights calculated from feature ranking,where classification accuracies were evaluated.The experimental results show that the effectiveness of the fusion of features generated from waveform and point cloud for LiDAR data classification,with 95.4% overall accuracy,0.90 kappa coefficient,which outperform the results obtained by a single class of features,no matter whether they were generated from point cloud or waveform data.
Ground-based GPS Used in the Snow Depth Survey of Greenland

Snow cover is one of the important components of land cover,and it is necessary to accurately monitor the depth and coverage of snow cover.Using the GPS signal receiver data and the basic principle of snow depth detection based on GPS-MR technology,the snow depth of the three sites on the Greenland PBO network GLS1,GLS2,and GLS3 from 2012 to 2018 was obtained.The inversion snow depth is affected by site drift,which is a quite difference from the measured snow depth.Combined with the stable reference point,the velocity field distribution of Greenland Island and the U-direction component change value of the station can be obtained through GAMIT calculation.By analyzing the glacial flow and U-direction component,the influence of the site drift on the snow depth was deducted,and finally compared the corrected inversion snow depth and measured snow depth found that the two were better than before the correction,the results were significantly improved,and the consistency was good.The analysis of the experimental results showed that in extremely cold areas such as Greenland Island,affected by glaciers,the continuous,real-time,high-time resolution snow depth around the measured station obtained by ground-based GPS tracking stations has a large gap with the measured snow depth value,and the gap will gradually increase with time.By deducting the impact of glacier drift,the trend of the two is the same and the consistency is good.The correctness and feasibility of the application of ground-based GPS snow cover theory in the polar area further expand the application scope and practical value of ground-based GPS in snow monitoring.
Observation of Offshore Wind Farm Wakes by Spaceborne Synthetic Aperture Radar

In this paper,studies on offshore wind farm wakes observed by spaceborne synthetic aperture radar (SAR) are reviewed mainly based on our previous research.Particularly,we focus on investigating wind wakes and tidal current wakes observed by spaceborne SAR of TerraSAR-X,Gaofen-3 and Radarsat-2 in high spatial resolution,in two offshores wind farms,i.e.,the Alpha Ventus in the North Sea and the one near Donghai bridge in the East China Sea.Representing examples of wind wakes and tidal current wakes observed by SAR in the two farms are presented and compared.A preliminary statistical analysis on morphology of wind feature downstream Alpha Ventus is presented as well.Besides these studies on wind wakes generated by a single offshore wind farm,we show an example of wakes downstream multiple wind farms in the North Sea to demonstrate "cluster"effect of multiple offshore wind farms on sea wind.
Geochronology and petrogeochemistry of Late Permian volcanic rocks in the B.Xiengnou area,Northwestern Laos:Petrogenesis and tectonic significance

The Nan Suture and Sukhothai Arc Terrane are products of the eastward subduction of the Paleotethyan Ocean during the Late Carboniferous to Triassic.However,their footprints in northwestern Laos are poorly constrained.New geochronological and geochemical data presented in this study demonstrate a Late Permian origin for the andesitic rocks in the B.Xiengnou area rather than Late Triassic.The brecciabearing andesitic tuff in the B.On ultramafic complex yield a zircon U-Pb age of 260 ± 1.4 Ma,geochemically displaying a MORB-like signature.The andesitic tuff in the B.Kiophoulan-B.Houayhak belt gave the U-Pb age of 254 ± 1.3 Ma,with arc-like geochemical affinity.By combining geochronological and geochemical data from the Nan Suture and Sukhothai Arc Terrane,the authors suggest that the andesitic rocks in the B.On ultramafic complex formed in a back-arc basin background,which connected the Jinghong and Nan back-arc basin during the Permian;while the andesitic tuff in the B.Kiophoulan-B.Houayhak belt erupted in the Sukhothai continental arc setting.
Zircon U-Pb ages and provenance characteristics of the Zhiluo Formation sandstones and the formation background of the uranium deposit in Huangling area,Ordos Basin,China

The newly discovered medium-scale Huangling uranium deposit is located in the Shuanlong area of the southeast Ordos Basin.This paper presents the systematic geochemical and zircon U-Pb studies on the Zhiluo Formation sandstones in the Huanling area.The data obtained play an important role in deducing the provenance and tectonic setting of the source rocks.The results show that the lower part of the Zhiluo Formation is mainly composed of felsic sedimentary rocks.The source rocks originated from a continental island arc environment in terms of tectonic setting.U-Pb ages of detrital zircons obtained can be roughly divided into three groups:170-500 Ma,1600-2050 Ma,and 2100-2650 Ma.Based on the characteristics of trace elements and rare earth elements (REE) and the zircon U-Pb dating results,it is considered that the Cryptozoic Edo provenance of the Zhiluo Formation mainly includes magmatic rocks (such as granodioritic intrusions) and metamorphic rocks (such as gneiss and granulite) in the orogenic belts on the northern margin of the North China Plate and in the Alxa Block.Based on sedimentological and petrological results,it can be concluded that the provenance of clastic sediments in the Zhiluo Formation was in north-south direction.The preconcentration of uranium is relatively low in the Lower Zhiluo Formation in the Huangling area.Meanwhile,the paleocurrent system in the sedimentary period is inconsistent with the ore-bearing flow field in the mineralization period,which restricts the formation of large-scale and super-large-scale uranium deposits and ore zones in the southeast Ordos Basin.The understanding of provenance directions will provide crucial references for the Jurassic prototype recovery and paleo-geomorphology of the Ordos Basin and the prediction of potential uranium reservoirs of the basin.

On October 22, 2020, the first 3000 m scientific deep drill for the solid mineral exploration area of the Qinghai-Tibet Plateau funded by the Ministry of Science and Technology was successfully completed in the Jiama copper polymetallic mining area (Fig. 1). The deep drill is the core task of a special project for Deep Resources Exploration and Mining (DREAM) in the framework of the National Key Research and Development Program (NKRDP), which named as "Deep exploration technology, exploration and reserve increases demonstration of the metallogenic system of the important mineral resource base in the Qinghai-Tibetan Plateau ". The project was undertaken by the Institute of Mineral Resources of China Geological Survey and Chengdu Center of China Geological Survey. The Shandong Provincial Third Geological and Mineral Exploration Institute is responsible for the deep drill construction. Since the start of construction on June 22, 2019, the construction team has overcome the effects of high cold and hypoxia and the Covid-19 epidemic,and completed on October 21, 2020, which lasted 488 days. The drilling footage of deep drilling is 3003.33 m, achieving a breakthrough of 3000 m deep drilling in the field of solid mineral exploration on the Qinghai-Tibet Plateau.
Petrology and metamorphism of glaucophane eclogites in Changning-Menglian suture zone, Bangbing area, southeast Tibetan Plateau: An evidence for Paleo-Tethyan subduction

High/ultrahigh-pressure (HP/UHP) metamorphic complexes, such as eclogite and blueschist, are generally regarded as significant signature of paleo-subduction zones and paleo-suture zones. Glaucophane eclogites have been recently identified within the Lancang Group characterized by accretionary melange in the Changning-Menglian suture zone, at Bangbing in the Shuangjiang area of southeastern Tibetan Plateau. The authors report the result of petrological, mineralogical and metamorphism investigations of these rocks, and discuss their tectonic implications. The eclogites are located within the Suyi blueschist belt and occur as tectonic lenses in coarse-grained garnet muscovite schists. The major mineral assemblage of the eclogites includes garnet, omphacite, glaucophane, phengite, clinozoisite and rutile. Eclogitic garnet contains numerous inclusions, such as omphacite, glaucophane, rutile, and quartz with radial cracks around. Glaucophane and clinozoisite in the matrix have apparent optical and compositional zonation. Four stages of metamorphic evolution can be determined: The prograde blueschist facies (M_1), the peak eclogite facies (M_2), the decompression blueschist facies (M_3) and retrograde greenschist facies (M_4). Using the Grt-Omp-Phn geothermobarometer, a peak eclogite facies metamorphic P-T condition of 3000-3270 MPa and 617-658°C was determined, which is typical of low-temperature ultrahigh-pressure metamorphism. The comparison of the geological characteristics of the Bangbing glaucophane eclogites and the Mengku lawsonite-bearing retrograde eclogites indicates that two suites of eclogites may have formed from significantly different depths or localities to create the tectonic melange in a subduction channel during subduction of the Triassic Changning-Menglian Ocean. The discovery of the Bangbing glaucophane eclogites may represent a new oceanic HP/UHP metamorphic belt in the Changning-Menglian suture zone.
