A Receiver Operating Characteristic(ROC)analysis of a power is important and useful in clinical trials.A Classical Conditional Power(CCP)is a probability of a classical rejection region given values of true treatment effect and interim result.For hypotheses and reversed hypotheses under normal models,we obtain analytical expressions of the ROC curves of the CCP,find optimal ROC curves of the CCP,investigate the superiority of the ROC curves of the CCP,calculate critical values of the False Positive Rate(FPR),True Positive Rate(TPR),and cutoff of the optimal CCP,and give go/no go decisions at the interim of the optimal CCP.In addition,extensive numerical experiments are carried out to exemplify our theoretical results.Finally,a real data example is performed to illustrate the go/no go decisions of the optimal CCP. 展开更多

Explorations into new electrolytes have highlighted the critical impact of solvation structure on battery performance,Classical molecular dynamics(CMD)using semi-empirical force fields has become an essential tool for simulating solvation structures.However,mainstream force fields often lack accuracy in describing strong ion-solvent interactions,causing disparities between CMD simulations and experimental observations.Although some empirical methods have been employed in some of the studies to address this issue,their effectiveness has been limited.Our CMD research,supported by quantum chemical calculations and experimental data,reveals that the solvation structure is influenced not only by the charge model but also by the polarization description.Previous empirical approaches that focused solely on adjusting ion-solvent interaction strengths overlooked the importance of polarization effects.Building on this insight,we propose integrating the Drude polarization model into mainstream force fields and verify its feasibility in carbonate,ether,and nitrile electrolytes.Our experimental results demonstrate that this approach significantly enhances the accuracy of CMD-simulated solvation structures.This work is expected to provide a more reliable CMD method for electrolyte design,shielding researchers from the pitfalls of erroneous simulation outcomes. 展开更多

This paper concerns the Cauchy problem of 3D compressible micropolar fluids in the whole space R^(3). For regular initial data with m0E0 is suitable small, where m0 and E0 represent the upper bound of initial density and initial energy, we prove that if ρ0 ∈ Lγ ∩ H3 with γ ∈ (1, 6), then the problem possesses a unique global classical solution on R^(3) × [0, T] with any T ∈ (0, ∞). It’s worth noting that both the vacuum states and possible random largeness of initial energy are allowed. 展开更多

This article examines the development of geomorpho-logical and hydrological research on karst landscapes in Central and Southeast Europe in the period before 1914.It provides novel insights into the introduction of the term“karst,”originally the name of a cavernous limestone plateau east of the Adriatic city of Trieste,as a universal model for comparing and understanding dissolutional features in soluble rocks.Based on a critical reappraisal of the sem-inal work“The Karst Phenomenon”(1893)by the Serbian geoscientist Jovan Cvijić(1865-1928),submitted as a Ph.D.thesis at the University of Vienna,my essay argues for a reassessment of the beginnings of karst sciences.It gives more attention to research as a cooperative enterprise and to the interplay between the internationalization of geosci-entific knowledge and the emerging national claims to the Balkan Peninsula and its inhabitants.Approaching the topic from a history of science perspective,I will analyze the epistemic,political,and social dimensions of early karst research at three different stages,namely,its emergence as an imperial undertaking in the Habsburg Monarchy,its synthesis and systematization through Cvijić’s“Karst Phenomenon,”and the final establishment of the Dinarides’northwestern part as the“Classical”Karst. 展开更多

Grass constitutes a vital poetic imagery in classical Chinese poetry,embodying multifaceted symbolic connotations ranging from the tenacity of life to sentiments of separation and nostalgic longing.The translation of this botanical motif necessitates not merely lexical equivalence,but more importantly,the transmission of its profound cultural resonance and aesthetic essence.This study posits that effective rendition of grass imagery should adopt an integrative approach synthesizing the objectives of cultural translation with the intrinsic aesthetic characteristics of classical poetry.Through systematic analysis of the cultural semiotics embedded in grass symbolism,the research investigates practical translation techniques at lexical,syntactic,and stylistic dimensions.The findings aim to contribute to the theoretical framework of cultural image translation in Chinese poetic tradition while providing methodological references for cross-cultural interpretation of classical verse.By bridging cultural semiotics with translation praxis,this investigation seeks to advance the intercultural communication of Chinese poetic heritage through nuanced treatment of its botanical symbolism. 展开更多

The presence of background classical sources affects quantum field theory significantly in different ways.Neutrino oscillation is a phenomenon that confirms that neutrinos are massive fermions in nature,a celebrated result in modern physics.Neutrino oscillation plays an important role in many astrophysical observations.However,the interactions between the background classical sources with neutrinos are not often considered.In the present article,we show the effect of some classical sources,namely matter currents,electromagnetic waves,torsion,and gravitational waves on neutrino oscillation.It is shown explicitly that the above sources can change the helicity state of neutrinos during neutrino oscillation. 展开更多

We investigate the mixed-state entanglement between two spins embedded in the XXZ Heisenberg chain under thermal equilibrium.By deriving an analytical expression for the entanglement of two-spin thermal states and extending this analysis to larger spin chains,we demonstrate that mixed-state entanglement is profoundly shaped by both disorder and temperature.Our results reveal a sharp distinction between many-body localized and ergodic phases,with entanglement vanishing above diferent fnite temperature thresholds.Furthermore,by analyzing non-adjacent spins,we uncover an approximate exponential decay of entanglement with separation.This work advances the understanding of the quantum-to-classical transition by linking the entanglement properties of small subsystems to the broader thermal environment,ofering an explanation for the absence of entanglement in macroscopic systems.These fndings provide critical insights into quantum many-body physics,bridging concepts from thermalization,localization,and quantum information theory. 展开更多

Molecular cloning remains a cornerstone technique in genetic engineering and synthetic biology.In this study,we conducted a systematic comparative analysis between the classical cloning method and the Golden Gate assembly technique,utilizing Escherichia coli as the model organism.Through polymerase chain reaction(PCR)amplification,restriction enzyme digestion,ligation,transformation,and Sanger sequencing,we assessed the operational efficiency and cloning fidelity of both strategies.Our results demonstrated that Golden Gate assembly,leveraging type IIS restriction enzymes and simultaneous ligation,significantly enhanced cloning efficiency and precision,particularly for seamless multi-fragment assembly.In contrast,the classical cloning approach maintained certain advantages in simplicity and robustness for specific experimental conditions.Challenges encountered during transformation and sequencing highlighted the critical impact of technical accuracy on experimental outcomes.This study underscores the importance of selecting appropriate cloning methodologies tailored to experimental objectives and laboratory capabilities,providing a foundation for optimized molecular cloning workflows in future synthetic biology and biotechnology applications. 展开更多

Objective Randomized controlled trials(RCTs)of Chinese patent medicines and classic tra-ditional Chinese medicine prescriptions were systematically reviewed from both Chinese and English journals published in 2023.A preliminary summary and evaluation were conducted on the generation and translation of clinical evidence for these treatments.This analysis aims to inform future research on clinical efficacy evaluation and guide the rational application of evidence.Methods RCTs of Chinese patent medicines and classic traditional Chinese prescriptions published in 2023 were comprehensively retrieved from the Artificial Intelligence Clinical Evi-dence Database for Chinese Patent Medicine(AICED-CPM),with supplementary searches conducted in China National Knowledge Infrastructure(CNKI),Wanfang Data,Chinese Sci-ence and Technology Journal Database(VIP),Chinese Biomedical Literature Database(SinoMed),Cochrane Library,PubMed,Embase,and Web of Science.The study characteris-tics and methodological quality of these RCTs were systematically analyzed and evaluated.Results A total of 1443 RCTs of Chinese patent medicines were included,comprising 1399 Chinese articles and 44 English articles.Additionally,334 RCTs of classic traditional Chinese medicine prescriptions were found,with 331 published in Chinese and 3 in English.196567 participants were included,covering 585 types of Chinese patent medicines(487 oral,61 in-jectable,and 37 topical)and 179 classic traditional Chinese medicine prescriptions.The in-volved studies encompassed 22 types of diseases,with research primarily focusing on dis-eases of the circulatory system,the respiratory system,and the genitourinary system.The sample sizes ranged from 18 to 3777 participants,and most studies were conducted at a sin-gle center.Methodologically,the implementation of allocation concealment and blinding re-mained insufficiently emphasized.Conclusion Overall,compared with 2022,both the number of RCT publications and their methodological quality have improved in 2023,with heightened attention to research on diseases of the genitourinary system.However,quality control and standardized management in the design and implementation processes still require enhancement to produce more high-quality clinical evidence and accelerate the translation and application of this evidence. 展开更多

BACKGROUND Surgically created arterio-venous fistulas(AVFs)are the gold standard for haemodialysis access for patients with end-stage renal disease.Standard practice of AVF creation involves selecting the non-dominant upper limb and starting with most distally with radio-cephalic arterio-venous fistula.The primary patency rate of radio-cephalic arterio-venous fistula varies from 20%-25%.It has been suggested the neointimal hyperplasia at the mobilized venous segment causes stenosis of the anastomosis.Therefore,the radial artery deviation and reimplantation(RADAR)technique,in which the vein is minimally mobilized,should result in a higher success rate.AIM To compare the RADAR technique with classical technique in creation of AVF including:(1)Success rate;(2)Time to maturation;(3)Duration of surgery;and(4)Complication rate.METHODS In our study we recruited 94 patients in two randomized groups and performed the AVF by the classical method or the RADAR method.RESULTS The RADAR group had higher primary success rate(P=0.007),less rate of complications(P=0.04),shorter duration of surgery(P=0.00)and early time to maturation(0.001)when compared with the classical group.The RADAR procedure is a safe and a more efficient alternative to the current classical method of AVF creation.Longer duration of follow-up is required to assess the long-term outcomes in the future.CONCLUSION The RADAR procedure is a safe and more efficient alternative to the current classical method of AVF creation.Longer duration of follow-up is required to assess the long-term outcomes in the future. 展开更多

The basic human rights concepts in Chinese classics mainly encompass three categories:the concept of order and freedom influenced by the worldview of the harmony between humanity and nature,the concept of human subjectivity and the source of human rights influenced by the people-oriented or benevolence-oriented values,as well as the concept of the relationship between human rights and state power guided by the outlook on life of the great unity of all under heaven(tianxia).Among them,the concept of order and freedom of the harmony between humanity and nature and modeling itself on nature is more beneficial to the stability and development of human society than the Western concept of order and freedom under“rational choice.”The norm prototype of“Do not do to others what you do not want others to do to you”formed the Article 4 of the French Declaration of the Rights of Man and of the Citizen in 1789,and the concepts of“benevolence”and“human superiority”were written into Article 1 of the Universal Declaration of Human Rights and the preamble of the Declaration of the United Nations Conference on the Human Environment,respectively,which have become the common spiritual wealth of all humankind.The ancient Chinese imperial examination system for selecting virtuous and capable people was basically consistent with the provisions on the political rights of citizens to hold public office stipulated in contemporary human rights documents,and was advanced in the world at that time.The contemporary Chinese system of“the state respects and protects human rights”is a system rooted in the Chinese historical and cultural traditions and is with the superiority of socialism. 展开更多

This paper introduces the Advanced Observer Model (AOM), a novel framework that integrates classical mechanics, quantum mechanics, and relativity through the observer’s role in constructing reality. Central to the AOM is the Static Configuration/Dynamic Configuration (SC/DC) conjugate, which examines physical systems through the interaction between static spatial configurations and dynamic quantum states. The model introduces a Constant Frame Rate (CFR) to quantize time perception, providing a discrete model for time evolution in quantum systems. By modifying the Schrödinger equation with CFR, the AOM bridges quantum and classical physics, offering a unified interpretation where classical determinism and quantum uncertainty coexist. A key feature of the AOM is its energy scaling model, where energy grows exponentially with spatial dimensionality, following the relationshipE∝(π)n. This dimensional scaling connects the discrete time perception of the observer with both quantum and classical energy distributions, providing insights into the nature of higher-dimensional spaces. Additionally, the AOM posits that spacetime curvature arises from quantum interactions, shaped by the observer’s discrete time perception. The model emphasizes the observer’s consciousness as a co-creator of reality, offering new approaches to understanding the quantum-classical transition. While speculative, the AOM opens new avenues for addressing foundational questions in quantum mechanics, relativity, dimensionality, and the nature of reality. 展开更多

The pathogenesis of orthopedic diseases is intimately linked to blood stasis,frequently arising from damage to primary and secondary blood channels.This disruption can lead to“blood leaving the meridians”or Qi stagnation,resulting in blood stasis syndrome.Taohong Siwu Decoction(THSWD)is a renowned classical Chinese medicinal formula extensively used to promote blood circulation and mitigate blood stasis.Clinical studies have demonstrated its significant therapeutic effects on various orthopedic conditions,particularly its anti-inflammatory and analgesic properties,as well as its efficacy in preventing deep vein thrombosis post-surgery.Despite these findings,research on THSWD remains fragmented,and its interdisciplinary impact is limited.This review aims to provide a comprehensive evaluation of the efficacy and pharmacological mechanisms of THSWD in treating common orthopedic diseases.Additionally,we employ bibliometric analysis to explore research trends and hotspots related to THSWD.We hope this review will enhance the recognition and application of THSWD in orthopedic treatments and guide future research into its pharmacological mechanisms. 展开更多

Neuromorphic hardware equipped with associative learn-ing capabilities presents fascinating applications in the next generation of artificial intelligence.However,research into synaptic devices exhibiting complex associative learning behaviors is still nascent.Here,an optoelec-tronic memristor based on Ag/TiO_(2) Nanowires:ZnO Quantum dots/FTO was proposed and constructed to emulate the biological associative learning behaviors.Effective implementation of synaptic behaviors,including long and short-term plasticity,and learning-forgetting-relearning behaviors,were achieved in the device through the application of light and electrical stimuli.Leveraging the optoelectronic co-modulated characteristics,a simulation of neuromorphic computing was conducted,resulting in a handwriting digit recognition accuracy of 88.9%.Furthermore,a 3×7 memristor array was constructed,confirming its application in artificial visual memory.Most importantly,complex biological associative learning behaviors were emulated by mapping the light and electrical stimuli into conditioned and unconditioned stimuli,respectively.After training through associative pairs,reflexes could be triggered solely using light stimuli.Comprehen-sively,under specific optoelectronic signal applications,the four features of classical conditioning,namely acquisition,extinction,recovery,and generalization,were elegantly emulated.This work provides an optoelectronic memristor with associative behavior capabilities,offering a pathway for advancing brain-machine interfaces,autonomous robots,and machine self-learning in the future. 展开更多

The data post-processing scheme based on two-way classical communication(TWCC)can improve the tolerable bit error rate and extend the maximal transmission distance when used in a quantum key distribution(QKD)system.In this study,we apply the TWCC method to improve the performance of reference-frame-independent quantum key distribution(RFI-QKD),and analyze the influence of the TWCC method on the performance of decoy-state RFI-QKD in both asymptotic and non-asymptotic cases.Our numerical simulation results show that the TWCC method is able to extend the maximal transmission distance from 175 km to 198 km and improve the tolerable bit error rate from 10.48%to 16.75%.At the same time,the performance of RFI-QKD in terms of the secret key rate and maximum transmission distance are still greatly improved when statistical fluctuations are considered.We conclude that RFI-QKD with the TWCC method is of practical interest. 展开更多

It is challenging to assess the mechanism responsible for the nucleation of inclusions in metals at high temperatures.The present work therefore systematically investigates the nucleation of cerium oxide inclusions according to classical nucleation theory and a two-step nucleation mechanism.The nucleation rates and nucleation radii of these inclusions are obtained,and the results demonstrate a considerable difference between theoretical and experimental values.On the basis of a two-step nucleation mechanism,(CeO_(2))_(n) and(Ce_(2)O_(3))_(n)(n=1-6)clusters were constructed and the thermodynamic properties of both these clusters and of cerium oxide nanoparticles were analyzed.In addition,the entropies and heat capacity changes of cerium oxides were determined using first principles calculations and are found to be consistent with literature data.The present data indicate that the cerium oxide inclusion nucleation pathway can be summarized as[Ce]+[O]→(CeO_(2))n/(Ce_(2)O_(3))_(n)→(Ce_(2)O_(3))_(n)→(Ce_(2)O_(3))_(2)→core(Ce_(2)O_(3)crystal)-shell((Ce_(2)O_(3))_(2) cluster)nanoparticles→(Ce_(2)O_(3))bulk. 展开更多
