Energy Minimization for Heterogenous Traffic Coexistence with Puncturing in Mobile Edge Computing-Based Industrial Internet of Things

Puncturing has been recognized as a promising technology to cope with the coexistence problem of enhanced mobile broadband(eMBB) and ultra-reliable low latency communications(URLLC)traffic. However, the steady performance of eMBB traffic while meeting the requirements of URLLC traffic with puncturing is a major challenge in some realistic scenarios. In this paper, we pay attention to the timely and energy-efficient processing for eMBB traffic in the industrial Internet of Things(IIoT), where mobile edge computing(MEC) is employed for data processing. Specifically, the performance of eMBB traffic and URLLC traffic in a MEC-based IIoT system is ensured by setting the threshold of tolerable delay and outage probability, respectively. Furthermore,considering the limited energy supply, an energy minimization problem of eMBB device is formulated under the above constraints, by jointly optimizing the resource blocks(RBs) punctured by URLLC traffic, data offloading and transmit power of eMBB device. With Markov's inequality, the problem is reformulated by transforming the probabilistic outage constraint into a deterministic constraint. Meanwhile, an iterative energy minimization algorithm(IEMA) is proposed.Simulation results demonstrate that our algorithm has a significant reduction in the energy consumption for eMBB device and achieves a better overall effect compared to several benchmarks.

Bipolar-growth multi-wing attractors and diverse coexisting attractors in a new memristive chaotic system

This article proposes a non-ideal flux-controlled memristor with a bisymmetric sawtooth piecewise function, and a new multi-wing memristive chaotic system(MMCS) based on the memristor is generated. Compared with other existing MMCSs, the most eye-catching point of the proposed MMCS is that the amplitude of the wing will enlarge towards the poles as the number of wings increases. Diverse coexisting attractors are numerically found in the MMCS, including chaos,quasi-period, and stable point. The circuits of the proposed memristor and MMCS are designed and the obtained results demonstrate their validity and reliability.

Corrigendum to “The transition from conservative to dissipative flows in class-B laser model with fold-Hopf bifurcation andcoexisting attractors”

Recently, we received a letter from Prof. G. L. Oppo, which indicated that he had doubts about the transformation of the system in the article Chin. Phys. B 31 060503 (2022) and gave other considerations. After inspection, we found that there was a clerical error in the article. Based on this, we have made corrections and supplements to the original article.

Synchronization coexistence in a Rulkov neural network based on locally active discrete memristor

At present, many neuron models have been proposed, which can be divided into discrete neuron models and continuous neuron models. Discrete neuron models have the advantage of faster simulation speed and the ease of understanding complex dynamic phenomena. Due to the properties of memorability, nonvolatility, and local activity, locally active discrete memristors(LADMs) are also suitable for simulating synapses. In this paper, we use an LADM to mimic synapses and establish a Rulkov neural network model. It is found that the change of coupling strength and the initial state of the LADM leads to multiple firing patterns of the neural network. In addition, considering the influence of neural network parameters and the initial state of the LADM, numerical analysis methods such as phase diagram and timing diagram are used to study the phase synchronization. As the system parameters and the initial states of the LADM change, the LADM coupled Rulkov neural network exhibits synchronization transition and synchronization coexistence.

Coexistence of giant Rashba spin splitting and quantum spin Hall effect in H–Pb–F

Rashba spin splitting(RSS)and quantum spin Hall effect(QSHE)have attracted enormous interest due to their great significance in the application of spintronics.In this work,we theoretically proposed a new two-dimensional(2D)material H–Pb–F with coexistence of giant RSS and quantum spin Hall effec by using the ab initio calculations.Our results show that H–Pb–F possesses giant RSS(1.21 eV·A)and the RSS can be tuned up to 4.16 e V·A by in-plane biaxial strain,which is a huge value among 2D materials.Furthermore,we also noticed that H–Pb–F is a 2D topological insulator(TI)duo to the strong spin–orbit coupling(SOC)interaction,and the large topological gap is up to 1.35 e V,which is large enough for for the observation of topological edge states at room temperature.The coexistence of giant RSS and quantum spin Hall effect greatly broadens the potential application of H–Pb–F in the field of spintronic devices.

Some of the Mechanisms for Coexistence of Tree Species Diversity in Tropical Forests: A Review of Effects of Tree Density Dependence

Tree communities contribute to maintenance of species diversity in tropical forests. Coexistence of many tree species is not without competition. Therefore, coexistence of tree species and size diversities occur sequentially or simultaneously in tropical natural forests. Understanding coexistence and competition mechanisms of tree species requires knowledge of interactions within and between species. However, many conservation efforts and strategies failed due to inability to identify and maintain functional coexistence mechanisms among tree species in the forest. Also, most trees died because of pressure on their habitats and not because of limiting growth resources. Hence, species identity, minimum distance and size of the neighbouring trees which are responsible for coexistence of competing trees in most tropical forests have not been explicitly reviewed. Therefore, this review evaluated some of the density dependent mechanisms for coexistence of tree species alpha diversity in tropical forests. Many interactive mechanisms are responsible for coexistence tree species in tropical forests. Inter- and intra-specific competitions are the most significant and both facilitate positive and negative density dependence. Therefore, switching from negative to positive density dependence may occur in some situations. Positive and negative density effects regulate species abundance and coexistence through conspecific and heterospecific structures. Aggregates of conspecific and heterospecific neighbours constitute forest spatial structure. Negative density interactions are mutually exclusive and basically ranged from effect of species identity of neighbours, distance to neighbours and tree size of the neighbours to reference trees in the community structures. Some mechanisms shorten distances for heterospecific than conspecific interactions. Conspecific structures improved survival and growth of rare tree species. Interactive mechanisms in tree community and population structures facilitate species diversity and size inequality, respectively.

Inferring Human-elephant Coexistence Based on Characteristics of Human-elephant Interactions in Nangunhe of Yunnan,China

Human-wildlife conflict(HWC)negatively impacts both humans and wildlife.Attitudes of local residents have been critical in promoting wildlife conservation.It is therefore necessary to understand the characteristics of HWC and identify influential factors on attitudes towards conservation to implement conservation strategies efficiently.This research focused on features of human-elephant interactions,while attitudes and values regarding the small population of Asian elephants(Elephas maximus)in Nangunhe National Nature Reserve(NNR),Yunnan,China.The total of 327 valid questionnaires were gathered around the area where Asian elephants were distributed.Logistic regression models were employed to analyze the correlations among five predictor variables(‘Area’,‘Family size’,‘Annual income’,‘Quantity of family members in non-primary industries’and‘Experiencing loss or not’)and three response variables(‘Attitude towards elephants’,‘Perception of the values of elephants’and‘Attitude towards tourism development’).The study area was densely forested with tea plants,rubber trees,corns and sugarcane.There,25.99%of respondents reported the experience of human-elephant conflict(HEC),with crop raiding and cash crop damages being the major conflict types.To demonstrate respect for elephants and to mitigate HEC,a unique custom called‘Giving tribute to elephants’was developed long ago.Respondents’township with an official annual festival of‘Giving Tribute to Elephants’(odds ratio(OR)=2.75,P=1.73×10^(-6))and higher annual income(OR=2.09,P=5.45×10^(-5))significantly contributed to forming a more positive attitude towards elephants,whereas HEC itself have contributed to a more negative attitude(OR=0.50,P=3.29×10^(-3)).Therefore,we propose that:1)reducing human-elephant conflict by testing multiple mitigation measures and adopting the most effective one of them;2)enhancing local livelihoods through the development of ecological products and ecotourism;and 3)preserving and developing the Wa culture in this region.The study area deserves more attention and further research to explore and obtain endorsement from the public to achieve coexistence between human and wildlife.

Protection and Restoration of Soil and Water Ecology to Achieve Harmonious Coexistence between Human and Nature

At present,the ecological environment crisis of global concern,such as climate warming and biodiversity loss,the fundamental reason is the change and destruction of the earth's soil and water ecology.Therefore,protecting and restoring the authenticity,diversity,cleanliness and integrity of soil and water ecology,we should coordinate and deal with the relationship between human beings and soil and water ecology,and realize the harmonious coexistence between human beings and nature from the three aspects of protecting natural soil and water ecology,protecting and restoring natural soil and water ecology,building and regenerating artificial soil and water ecology.

Coexistence of diffuse large B-cell lymphoma,acute myeloid leukemia,and untreated lymphoplasmacytic lymphoma/waldenström macroglobulinemia in a same patient:A case report

BACKGROUND The Coexistence of myeloid and lymphoid malignancies is rare.Myeloid leukemia occurs more frequently as a secondary event in patients receiving chemotherapy agents for lymphoid malignancies.Synchronous diagnoses of diffuse large B-cell lymphoma(DLBCL),acute myeloid leukemia(AML),and untreated lymphoplasmacytic lymphoma/Waldenström macroglobulinemia(LPL/WM)in the same patient have not been reported.Here we report one such case.CASE SUMMARY An 89-year-old man had a chest wall mass histopathologically diagnosed as DLBCL.The bone marrow and peripheral blood contained two groups of cells.One group of cells fulfilled the criteria of AML,and the other revealed the features of small B lymphocytic proliferative disorder,which we considered LPL/WM.Multiple chromosomal or genetic changes were detected in bone marrow mononuclear cells,including ATM deletion,CCND1 amplification,mutations of MYD88(L265P)and TP53,WT1 overexpression,and fusion gene of BIRC2-ARAP1,as well as complex chromosomal abnormalities.The patient refused chemotherapy because of old age and died of pneumonia 1 mo after the final diagnosis.CONCLUSION The coexistence of DLBCL,AML,and untreated LPL/WM in the same patient is extremely rare,which probably results from multiple steps of genetic abnormalities.Asymptomatic LPL/WM might have occurred first,then myelodysplastic syndromerelated AML developed,and finally aggressive DLBCL arose.Therefore,medical staff should pay attention to this rare phenomenon to avoid misdiagnoses.

Coexistence of Pseudotumor Cerebri and Chiari Malformation Type 1

Objective:To identify different radiological markers for the diagnosis of the coexistence of pseudotumor cerebri and Chiari malformation type 1.Method:Patients who were clinically suspected to have Chiari malformation type 1 and were referred to the Department of Radiology between 2007 and 2020,and whose diagnosis was radiologically confirmed through magnetic resonance imaging(MRI),were retrospectively evaluated.A total of 49 Chiari malformation type 1 patients with both cervical and cerebral examinations and 49 control subjects of the same age and gender without a diagnosis of Chiari malformation type 1 were included in the study.In Chiari malformation type 1 diagnosed patients,the presence of pseudotumor cerebri,the presence of syringomyelia in cervical spinal MRI images,and the distance of cerebellar tonsils and obex according to McRae line were evaluated in millimeters.Result:In Chiari malformation type 1 clinically and radiologically diagnosed cases,the cerebellar tonsils and obex were located lower in patients with a radiological diagnosis of pseudotumor cerebri compared to those without,and the rate of accompanying syringomyelia appeared to be higher.However,no statistically significant difference was observed between the two groups.Conclusion:The coexistence of pseudotumor cerebri and Chiari malformation type 1 is more common than previously estimated.Different treatment protocols in the coexistence of pseudotumor cerebri and Chiari malformation type 1 emphasize the importance of making this diagnosis.Further radiological imaging studies are needed to identify different radiological markers for the diagnosis of the coexistence of pseudotumor cerebri and Chiari malformation type 1.

中国式现代化与绿色发展

中国式现代化是人与自然和谐共生的现代化,绿色发展是其显著特征和突出品质。中国积极推进生态环境建设,人与自然的关系相应地从生态赤字缓慢扩大期、生态赤字快速扩大期、再进入生态赤字缩小期、局部生态盈余期,未来将转向生态盈余期。党的十八大以来,中国生态文明建设在生态环境质量改善、生态保护修复、绿色低碳转型、全球生态治理贡献、中国特色制度体系创新等方面发生了历史性、转折性、全局性变化,但生态环境保护仍面临基础性问题,结构性压力、根源性压力、趋势性压力尚未根本缓解。为此,中国必须坚持长期主义,避免短期机会主义,坚持绿色增长,追求绿色发展的长期价值,并以绿色发展推进人与自然和谐共生现代化,即高质量发展与高水平保护统筹推进,整体推进与重点攻坚协同并进,科技创新与制度创新双轮驱动,正向激励与反向倒逼双向发力,多元参与与协同治理并行不悖,实践探索和经验总结紧密结合。

中国式现代化的形态建构、动力要素与实践进路——以人与自然和谐共生为分析视角

中国式现代化是中国共产党立足人类文明和现代化发展规律,坚持把马克思主义基本原理同中国具体实际相结合、同中华优秀传统文化相结合的重大成果,超越了西方现代化道路与模式。文本以人与自然和谐共生为视角展开对中国式现代化的形态建构,从政治领导力量、文化因素、经济因素、制度因素和技术因素等方面探讨实现中国式现代化的动力要素;指出中国式现代化的推进始终坚持中国共产党领导,坚持中国特色社会主义,坚持以人民为中心的发展思想,坚持人与自然和谐共生,走生态文明发展的现代化新道路,追求“五个文明”相协调和全体人民共同富裕的价值目标,既为后发国家独立自主实现现代化提供了全新选择,又创造出人类文明新形态。

面向人与自然和谐共生的环境党内法规的治理逻辑

建设面向人与自然和谐共生的中国式现代化,中国式法治化是必然要求,其中环境法治不可或缺。中国式的环境法治必然要重视党内法规的特殊法治和治理功能。可从着力发挥党内法规在环境法治中的特殊作用、统筹推进环境综合治理的规范功能、推动构建人类环境命运共同体的制度文明三方面,揭示出环境党内法规所秉持环境系统观、环境效能观、环境文明观的政理法理。环境党内法规有广义和狭义之分,环境党内法规所承载上述治理逻辑的规范样态,不仅包括符合《中国共产党党内法规制定条例》严格形式要件的狭义党内法规,也包括引领环境法治发展的环境政策、起到监督保障等作用的党内环境规范性文件。从环境党内法规的政治功能和规范效力来讲,将以决议、决定、意见、通知等为主要载体的环境政策视为广义的环境党内法规,符合新形势下环境党内法规体系构筑的核心要义。从目前党内法规体系的构成情况看,起到监督保障作用的党内环境规范性文件成为了主力军,但其数量庞杂又单线作战的实践困境使其亟需完善以形成治理合力。因此,应进一步探讨党的环境政策和党内环境规范性文件向狭义党内法规的有机转化,使狭义的环境党内法规成为环境党内法规体系的主体部分。广义视阈下的环境党内法规,在面向人与自然和谐共生的现代化中发挥着规范、治理与重塑的制度功能。环境党内法规通过将党的不成文的环境文明提炼转化为具有约束力的制度形态,从而使其获得长远的效能力和长期的执行力。环境党内法规通过为生态文明建设提供制度赋能,从而全面发挥其环境治理的政治效能、预防效能和发展效能。环境党内法规以党的领导为本质特征的政治结构为环境文明奠基、以人民为中心的人本理念为环境文明铸魂、以党规国法共治为保障的外部制度为环境文明塑形,使其实质上具备了打造人类环境文明新形态的重塑功能。需要注意的是,完备的环境党内法规体系对上述功能的系统发挥尤为重要,因此,面向人与自然和谐共生的环境党内法规,还有待进一步体系化完善。

经济绿色发展对资本主义“自然悖论”的超越

在世界历史的进程中,资本主义大工业将科学和自然力运用到生产过程中,促进了生产力的进步与技术的提升。然而,由于资本主义的生产以价值增殖为根本目的,其最终成为生产力发展的桎梏和生态环境受到污染和破坏的根源,因此造成了不可避免的“自然悖论”。资本本性的剥削性和无限扩张特征,促使其对生态环境无止境地滥用与掠夺,资本主义再生产在充分利用生态环境的过程中造成了人与自然、人与人的“物质变换断裂”,产生了各种“城市病”和“文明病”。不同于资本主义“竭泽而渔”式的发展,以习近平同志为核心的党中央在经济发展方面始终坚持走绿色发展道路,推进人与自然和谐共生的现代化建设,强调经济社会发展与生态环境保护的具体的历史的统一。面对资本主义的“自然悖论”及其造成的“文明病”,中国特色社会主义的绿色发展理念坚持和发展了马克思主义理论,坚定不移走中国特色社会主义道路,奠定了高质量发展和高水平保护的制度性基础,促进了环境正义与社会正义的相互融合,在未来社会的绿色变革中发挥着重要作用。

多病共存慢性病患者内脏康复的研究进展

随着慢性病发病率及患病率逐年增加,多病共存现象日益普遍。内脏康复是以运动为主的一种综合性干预手段,可以改善慢性病患者的脏器功能,提高其生活质量。目前多病共存慢性病患者的内脏康复尚处于探索阶段。多病共存慢性病患者行内脏康复前需进行一系列评估,基于国际功能、残疾和健康分类模式构建以功能学分类为基础的内脏康复评估体系可能是未来的发展方向。多病共存慢性病患者运动处方的制订需更加关注安全性、有效性和依从性,而最低限度标准化运动处方可能作为个性化运动处方的替代方案。

鄂尔多斯盆地庆阳气田二叠系山西组山_(1)^(3)沉积相类型论证

鄂尔多斯盆地庆阳气田山1段是其主力产层,其沉积环境及其相类型一直争议较多,不同认识导致各个沉积相域内砂体对比模式和砂体分布形态存在着一定差异,从而给勘探井位部署增加了难度。在前人研究成果基础上,综合地震、测井、岩心、露头及室内分析化验等资料,结合地震反射结构揭示的溯源退覆特征、岩心显示的岩性粒度与层理构造、测井沉积旋回特征、现代沉积学的比较等等多视角证据链,对该区山_(1)^(3)小层的沉积相进行了详细论证、分析和描述。研究结果表明,研究区岩性以中粗砂岩为主,多发育块状、板状及小型槽状交错层理,测井相既有河流“二元结构”发育完整的井段,也有只发育下部粗粒端元河流“二元结构”发育不完整的井段,前者揭示发育曲流河,后者则与辫状河发育有关;粒度分析结果显示主要以跳跃粒度成分为主,说明古水动力强;研究区周边露头资料显示既有曲流河发育也有辫状河发育,说明山1段沉积期曲流河和辫状河是同期存在的;现代卫星照片揭示,曲流河和辫状河共生共存发育是普遍存在的,综合上述证据,最终确定研究区山31发育相类型为河流相,且表现为曲辫共存特征,曲流河的频繁侧积以及平面多种河型共存,垂向河道的多期叠置是导致砂体分布复杂化和横向相变化快速的主控因素。
