Self-serving,rational agents sometimes cooperate to their mutual benefit.The two-player iterated prisoner′s dilemma game is a model for including the emergence of cooperation.It is generally believed that there is no simple ultimatum strategy which a player can control the return of the other participants.The zero-determinant strategy in the iterated prisoner′s dilemma dramatically expands our understanding of the classic game by uncovering strategies that provide a unilateral advantage to sentient players pitted against unwitting opponents.However,strategies in the prisoner′s dilemma game are only two strategies.Are there these results for general multi-strategy games?To address this question,the paper develops a theory for zero-determinant strategies for multi-strategy games,with any number of strategies.The analytical results exhibit a similar yet different scenario to the case of two-strategy games.The results are also applied to the Snowdrift game,the Hawk-Dove game and the Chicken game. 展开更多

Na_(3)V_(2)(PO_(4))_(3)(NVP)has garnered great attentions as a prospective cathode material for sodium-ion batteries(SIBs)by virtue of its decent theoretical capacity,superior ion conductivity and high structural stability.However,the inherently poor electronic conductivity and sluggish sodium-ion diffusion kinetics of NVP material give rise to inferior rate performance and unsatisfactory energy density,which strictly confine its further application in SIBs.Thus,it is of significance to boost the sodium storage performance of NVP cathode material.Up to now,many methods have been developed to optimize the electrochemical performance of NVP cathode material.In this review,the latest advances in optimization strategies for improving the electrochemical performance of NVP cathode material are well summarized and discussed,including carbon coating or modification,foreign-ion doping or substitution and nanostructure and morphology design.The foreign-ion doping or substitution is highlighted,involving Na,V,and PO_(4)^(3−)sites,which include single-site doping,multiple-site doping,single-ion doping,multiple-ion doping and so on.Furthermore,the challenges and prospects of high-performance NVP cathode material are also put forward.It is believed that this review can provide a useful reference for designing and developing high-performance NVP cathode material toward the large-scale application in SIBs. 展开更多

Gastric cancer ranks fifth as the most common cancer and third as the leading cause of death worldwide.Risk factors include advancing age,low-fiber diets,high salt intake and Helicobacter pylori infection.Diagnosis relies on histological examination following endoscopic biopsy with staging accomplished through various imaging modalities.Early gastric cancer is primarily managed via endoscopic resection,while non-early operable cases typically undergo surgery.Advanced cases are addressed through sequential chemotherapy lines,with initial treatment usually comprising a platinum and fluoropyrimidine combination.Linitis plastica(LP)is a rare,aggressive form of gastric cancer characterized by diffuse infiltration of the gastric wall,resulting in poor outcomes even after curative resection.The absence of a standardized definition contributes to uncertainty regarding the precise incidence of these tumors.LP is often diagnosed at advanced stages,with a reported median survival rate of approximately 4%-29%,despite“curative resection”.Its distinctive biological behavior includes perineural invasion,nodal metastasis,and peritoneal dissemination.The bleak prognosis for LP patients partly stems from delayed diagnosis and its aggressive biological nature,posing significant challenges for clinical management.Currently,no specialized treatment strategy exists for LP,and clinical approaches typically align with those used for general gastric cancer treatment.Surgical resection is the primary treatment,but the optimal surgical approach remains contentious.Recent studies have investigated the efficacy of neoadjuvant chemotherapy and radiotherapy in improving survival outcomes for LP patients.However,controversies persist regarding the role of adjuvant chemotherapy and postoperative radiotherapy.LP requires a multidisciplinary approach and personalized treatment strategies tailored to each patient’s condition.Further research is needed to elucidate optimal therapeutic interventions and improve outcomes for LP patients. 展开更多

The Yangtze River economic belt(YREB),China is important to the Chinese economy and for supporting sustainable development.Clarifying the relationship between water quality indices and socioeconomic indicators could help improve aquatic environment management in the YREB and our understanding of the causes and effects of water quality variations in other large river basins.In this study,river water quality,factors affecting water quality,and management strategies,and correlations between water quality indices and socioeconomic indicators in the YREB during the 13th Five-Year Plan period(2016-2020)were assessed.The single-factor evaluation method,constant price for GDP,and correlation analyses were adopted.The results showed that:1)water quality in the YREB improved during the 13th Five-Year Plan period.The number of aquatic environment sections meeting GradeⅠ-Ⅲwater quality standards increased by 13.1%and the number below Grade V decreased by 2.9%.2)The values of 12 indicators in the YREB exceeded relevant standards.The indicators with highest concentreation were the total phosphorus,chemical oxygen demand,ammonia nitrogen,and permanganate index,which were relatively high in downstream regions in Anhui Province,Jiangsu Province,and Shanghai Municipality.3)Ammonia nitrogen,chemical oxygen demand,and total phosphorus emissions per unit area and water extraction per unit area are relatively high in the three downstream regions mentioned above.4)Increased domestic sewage discharges have increased total wastewater discharges in the YREB.5)River water quality in the YREB strongly correlated with population,economic,and water resource indices and less strongly correlated with government investment,agriculture,meteorology,energy,and forestry indices.This confirmed the need to decrease wastewater discharges and non-point-source pollutant emissions.The aquatic environment could be improved by taking reasonable measures to control population growth,adjusting the industrial structure to accelerate industrial transformation and increase the proportion of tertiary industries,and investing in technological innovations to protect the environment. 展开更多

This paper proposes recommendations for probiotics in pediatric gastrointestinal diseases in the Asia-Pacific region. Epidemiology and clinical patterns of intestinal diseases in Asia-Pacific countries were discussed. Evidence-based recommendations and randomized controlled trials in the region were revised. Cultural aspects,health management issues and economic factors were also considered. Final recommendations were approved by applying the Likert scale and rated using the GRADE system. Saccharomyces boulardii CNCM I-745(Sb) and Lactobacillus rhamnosus GG(LGG) were strongly recommended as adjunct treatment to oral rehydration therapy for gastroenteritis. Lactobacillus reuteri could also be considered. Probiotics may be considered for prevention of(with the indicated strains): antibiotic-associated diarrhea(LGG or Sb); Clostridium difficile-induced diarrhea(Sb); nosocomial diarrhea(LGG); infantile colic(L reuteri) and as adjunct treatment of Helicobacter pylori(Sb and others). Specific probiotics with a history of safe use in preterm and term infants may be considered in infants for prevention of necrotizing enterocolitis. There is insufficient evidence for recommendations in other conditions. Despite a diversity of epidemiological,socioeconomical and health system conditions,similar recommendations apply well to Asia pacific countries. These need to be validated with local randomized-controlled trials. 展开更多

Climate change is a threat to the stability and productivity of forest ecosystems throughout the AsiaPacific region. The loss of forests due to climate-induced stress will have extensive adverse impacts on biodiversity and an array of ecosystem services that are essential for the maintenance of local economies and public health. Despite their importance, there is a lack of decision-support tools required to evaluate the potential effects of climate change on Asia-Pacific ecosystems and economies and to aid in the development of regionally appropriate adaptation and mitigation strategies. The project Adaptation of AsiaPacific Forests to Climate Change, summarized herein,aims to address this lack of knowledge and tools and to provide support for regional managers to develop effective policy to increase the adaptive capacity of Asia-Pacific forest ecosystems. This objective has been achieved through the following activities:(1) development of a highresolution climate downscaling model, Climate AP, applicable to any location in the region;(2) development of climate niche models to evaluate how climate change might affect the distribution of suitable climatic conditions for regionally important tree species;(3) development and application of forest models to assess alternative management strategies in the context of management objectives and the projected impacts of climate change;(4) evaluation of models to assess forest fire risk and the relationship between forest fire and climate change;(5) development of a technique to assess ecosystem carbon storage using Li DAR; and(6) evaluation of how vegetation dynamics respond to climate change using remote sensing technology. All project outputs were developed with a focus on communication and extension to facilitate the dissemination of results to regional forest resource managers to support the development of effective mitigation and adaptation policy. 展开更多

BACKGROUND Major societies provide differing guidance on management of Barrett’s esophagus(BE),making standardization challenging.AIM To evaluate the preferred diagnosis and management practices of BE among Asian endoscopists.METHODS Endoscopists from across Asia were invited to participate in an online questionnaire comprising eleven questions regarding diagnosis,surveillance and management of BE.RESULTS Five hundred sixty-nine of 1016(56.0%)respondents completed the survey,with most respondents from Japan(n=310,54.5%)and China(n=129,22.7%).Overall,the preferred endoscopic landmark of the esophagogastric junction was squamocolumnar junction(42.0%).Distal palisade vessels was preferred in Japan(59.0%vs 10.0%,P<0.001)while outside Japan,squamo-columnar junction was preferred(59.5%vs 27.4%,P<0.001).Only 16.3%of respondents used Prague C and M criteria all the time.It was never used by 46.1%of Japanese,whereas 84.2%outside Japan,endoscopists used it to varying extents(P<0.001).Most Asian endoscopists(70.8%)would survey long-segment BE without dysplasia every two years.Adherence to Seattle protocol was poor with only 6.3%always performing it.73.2%of Japanese never did it,compared to 19.3%outside Japan(P<0.001).The most preferred(74.0%)treatment of non-dysplastic BE was proton pump inhibitor only when the patient was symptomatic or had esophagitis.For BE with low-grade dysplasia,6-monthly surveillance was preferred in 61.9%within Japan vs 47.9%outside Japan(P<0.001).CONCLUSION Diagnosis and management of BE varied within Asia,with stark contrast between Japan and outside Japan.Most Asian endoscopists chose squamo-columnar junction to be the landmark for esophagogastric junction,which is incorrect.Most also did not consistently use Prague criteria,and Seattle protocol.Lack of standardization,education and research are possible reasons. 展开更多

Social capital in the form of social resources or social networks is one of the most important livelihood capital of farmers, which can increase the labor productivity of poor households and increase income. It is important to explore the reasons underlying the livelihood strategy choices of farmers from the perspective of social capital under China’s rural revitalization strategy. In this study, the Liangshan Yi Autonomous Prefecture, a povertystricken mountainous area in southwestern China, was selected as the case study area, and multivariable linear regression models were constructed to analyze the influence of social capital on livelihood strategies.The results are as follows:(1) Individual social capital had a positive effect on non-agricultural livelihood strategies. On average, with a one-unit increase in individual social capital, the ratio of farmers’ nonagricultural income to total productive income(Income_Rto) increased by 0.002% and 0.062%,respectively. Collective social capital, with the Peasant Economic Cooperation Organization(PECO) as the carrier, had a negative effect on the non-agricultural livelihood strategies of farmers;on average, with a oneunit increase in PECO, Income_Rto decreased by approximately 0.053%. However, this effect was only significant in the river valley area.(2) The income differences among the different livelihood strategy types were explained by the livelihood strategy choices of farmers. As non-agricultural work can bring more benefits, the labor force exhibited one-way migration from villages to cities, resulting in a lack of the subject of rural revitalization. It is necessary to implement effective measures to highlight the role of PECO in increasing agricultural income for farmers. Finally,based on the above conclusions,policy recommendations with respect to livelihood transformation of farmers and rural sustainable development are discussed. 展开更多

The National Centers for Environmental Prediction (NCEP) reanalysis data, Climate Diagnostics Center Merged Analysis of Precipitation (CMAP) results, and NOAA Extended Reconstructed Sea Surface Temperature (SST), have been utilized in this paper to study the quasi-biennial variations in Asia-Pacific monsoon subsystems and associated SST anomalies (SSTA) and wind anomalies. Four monsoon indices are computed from NCEP/ National Center for Atmospheric Research (NCAR) reanalysis to represent the South Asian monsoon (SAM), South China Sea summer monsoon (SCSSM), Western North Pacific monsoon (WNPM) and East Asian monsoon (EAM), respectively. The quasi-biennial periods are very significant in Asia-Pacific monsoons (as discovered by power spectrum analysis), and for SAM and EAM---with moderate effects by El Ni?o-Southern Oscillation (ENSO)---the quasi-biennial periods are the most important factor. For SCSSM and WNPM (once again due to the effects of ENSO), the quasi-biennial periods are of secondary durations. There are obvious interdecadal variations in the quasi-biennial modes of the Asia-Pacific monsoon, so in the negative phase the biennial modes will not be significant or outstanding. The wind anomalies and SSTA associated with the biennial modes are very different in the SAM, WNPM and EAM regions. Since the WNPM and SCSSM are very similar in the biennial modes, they can be combined into one subsystem, called SCS/WNPM. 展开更多

At the end of 2015, the United States lifted a 40-year ban on crude oil exports, which has far-reaching implications for the global crude oil market and crude oil trade patterns. Since the release of crude oil exports, with the recovery of crude oil production and improved export infrastructure in the United States, U.S. crude oil exports have been growing rapidly, with an average of about one million barrels/day in 2017, making the U.S one of the major global crude oil exporters. Currently, the AsiaPacific region has replaced North America as the first major destination for U.S. crude oil exports. In light of future trends in the oil refining industry of the Asia-Pacific region, it will usher in a new wave of refinery operations around 2020 and crude oil imports will continue to grow rapidly. The American region, represented by the United States, will replace West Africa as the second largest source of crude oil imports to the Asia-Pacific region, and that energy trade cooperation between the Asia-Pacific region and the United States will continue to grow. In particular, for China, the United States will become an important source of crude oil imports for our country in the future, and the two countries will shift from the past of energy competition to energy cooperation. Sino-US energy trade will play a more active role in economic and trade cooperation between the two countries. 展开更多

BACKGROUND Intensive care unit-acquired weakness(ICU-AW)is a common complication that significantly impacts the patient's recovery process,even leading to adverse outcomes.Currently,there is a lack of effective preventive measures.AIM To identify significant risk factors for ICU-AW through iterative machine learning techniques and offer recommendations for its prevention and treatment.METHODS Patients were categorized into ICU-AW and non-ICU-AW groups on the 14th day post-ICU admission.Relevant data from the initial 14 d of ICU stay,such as age,comorbidities,sedative dosage,vasopressor dosage,duration of mechanical ventilation,length of ICU stay,and rehabilitation therapy,were gathered.The relationships between these variables and ICU-AW were examined.Utilizing iterative machine learning techniques,a multilayer perceptron neural network model was developed,and its predictive performance for ICU-AW was assessed using the receiver operating characteristic curve.RESULTS Within the ICU-AW group,age,duration of mechanical ventilation,lorazepam dosage,adrenaline dosage,and length of ICU stay were significantly higher than in the non-ICU-AW group.Additionally,sepsis,multiple organ dysfunction syndrome,hypoalbuminemia,acute heart failure,respiratory failure,acute kidney injury,anemia,stress-related gastrointestinal bleeding,shock,hypertension,coronary artery disease,malignant tumors,and rehabilitation therapy ratios were significantly higher in the ICU-AW group,demonstrating statistical significance.The most influential factors contributing to ICU-AW were identified as the length of ICU stay(100.0%)and the duration of mechanical ventilation(54.9%).The neural network model predicted ICU-AW with an area under the curve of 0.941,sensitivity of 92.2%,and specificity of 82.7%.CONCLUSION The main factors influencing ICU-AW are the length of ICU stay and the duration of mechanical ventilation.A primary preventive strategy,when feasible,involves minimizing both ICU stay and mechanical ventilation duration. 展开更多

Lithium–sulfur(Li–S)batteries are supposed to be one of the most potential next-generation batteries owing to their high theoretical capacity and low cost.Nevertheless,the shuttle effect of firm multi-step two-electron reaction between sulfur and lithium in liquid electrolyte makes the capacity much smaller than the theoretical value.Many methods were proposed for inhibiting the shuttle effect of polysulfide,improving corresponding redox kinetics and enhancing the integral performance of Li–S batteries.Here,we will comprehensively and systematically summarize the strategies for inhibiting the shuttle effect from all components of Li–S batteries.First,the electrochemical principles/mechanism and origin of the shuttle effect are described in detail.Moreover,the efficient strategies,including boosting the sulfur conversion rate of sulfur,confining sulfur or lithium polysulfides(LPS)within cathode host,confining LPS in the shield layer,and preventing LPS from contacting the anode,will be discussed to suppress the shuttle effect.Then,recent advances in inhibition of shuttle effect in cathode,electrolyte,separator,and anode with the aforementioned strategies have been summarized to direct the further design of efficient materials for Li–S batteries.Finally,we present prospects for inhibition of the LPS shuttle and potential development directions in Li–S batteries. 展开更多
