This paper proposes an alternative approach for constructing a knowledge graph (KG) from a PDF document with a focus on simplicity and cost-effectiveness. The process involves splitting the document into chunks, extracting concepts within each chunk using a large language model (LLM), and building relationships based on the proximity of concepts in the same chunk. Unlike traditional named entity recognition (NER), which identifies entities like “Shanghai”, the proposed method identifies concepts, such as “Convenient transportation in Shanghai” which is found to be more meaningful for KG construction. Each edge in the KG represents a relationship between concepts occurring in the same text chunk. The process is computationally inexpensive, leveraging locally set up tools like Mistral 7B openorca instruct and Ollama for model inference, ensuring the entire graph generation process is cost-free. A method of assigning weights to relationships, grouping similar pairs, and summarizing multiple relationships into a single edge with associated weight and relation details is introduced. Additionally, node degrees and communities are calculated for node sizing and coloring. This approach offers a scalable, cost-effective solution for generating meaningful knowledge graphs from large documents, achieving results comparable to GraphRAG while maintaining accessibility for personal machines.展开更多

Traditionally, bariatric surgeries have been categorized into hypoabsorptive, restrictive, or hybrid approaches. However, these classifications inadequately reflect the complex anatomical and physiological alterations associated with modern surgical methodologies. This paper explores the evolution of metabolic surgeries, emphasizing the integration of physiological concepts into classic procedures to provide more tailored and effective treatment options for obesity and its comorbidities. Finally, the proposal for a new classification based on current metabolic concepts will facilitate communication among patients, doctors, and healthcare professionals. Additionally, it will enable a more didactic and standardized approach to data collection for conducting studies and publications.展开更多

文摘Processes supported by process-aware information systems are subject to continuous and often subtle changes due to evolving operational,organizational,or regulatory factors.These changes,referred to as incremental concept drift,gradually alter the behavior or structure of processes,making their detection and localization a challenging task.Traditional process mining techniques frequently assume process stationarity and are limited in their ability to detect such drift,particularly from a control-flow perspective.The objective of this research is to develop an interpretable and robust framework capable of detecting and localizing incremental concept drift in event logs,with a specific emphasis on the structural evolution of control-flow semantics in processes.We propose DriftXMiner,a control-flow-aware hybrid framework that combines statistical,machine learning,and process model analysis techniques.The approach comprises three key components:(1)Cumulative Drift Scanner that tracks directional statistical deviations to detect early drift signals;(2)a Temporal Clustering and Drift-Aware Forest Ensemble(DAFE)to capture distributional and classification-level changes in process behavior;and(3)Petri net-based process model reconstruction,which enables the precise localization of structural drift using transition deviation metrics and replay fitness scores.Experimental validation on the BPI Challenge 2017 event log demonstrates that DriftXMiner effectively identifies and localizes gradual and incremental process drift over time.The framework achieves a detection accuracy of 92.5%,a localization precision of 90.3%,and an F1-score of 0.91,outperforming competitive baselines such as CUSUM+Histograms and ADWIN+Alpha Miner.Visual analyses further confirm that identified drift points align with transitions in control-flow models and behavioral cluster structures.DriftXMiner offers a novel and interpretable solution for incremental concept drift detection and localization in dynamic,process-aware systems.By integrating statistical signal accumulation,temporal behavior profiling,and structural process mining,the framework enables finegrained drift explanation and supports adaptive process intelligence in evolving environments.Its modular architecture supports extension to streaming data and real-time monitoring contexts.

文摘Bariatric and metabolic surgeries have gained extensive popularity and trust due to their documented efficacy and safety in managing not only obesity but also associated comorbidities such as diabetes mellitus, hypertension, dyslipidemia, sleep apnea, and joint pain. Traditionally, bariatric surgeries have been categorized into hypoabsorptive, restrictive, or hybrid approaches. However, these classifications inadequately reflect the complex anatomical and physiological alterations associated with modern surgical methodologies. This paper explores the evolution of metabolic surgeries, emphasizing the integration of physiological concepts into classic procedures to provide more tailored and effective treatment options for obesity and its comorbidities. Finally, the proposal for a new classification based on current metabolic concepts will facilitate communication among patients, doctors, and healthcare professionals. Additionally, it will enable a more didactic and standardized approach to data collection for conducting studies and publications.
文摘Objectives:This study aimed to establish the concept of overcoming exhaustion,providing a reference basis for nursing management and conducting related nursing research.Methods:Liehr and Smith’s three-phase,nine-step concept-building process was used to create the concept of overcoming exhaustion.The nine steps were as follows:1)write a practice story;2)name the emerging concept;3)select a theoretical lens;4)link concept to literature;5)gather a concept story;6)identify final core qualities;7)formulate concept definition;8)create a concept model;and 9)specify the concept building synthesis.Results:The concept of overcoming exhaustion was identified based on the elements of a practice story,the life experiences of nurses who struggle with the demands of caring for their patients,their families,and themselves.The theory of self-transcendence was then recognized as the theoretical lens from which to ground the concept.The core qualities,despair and moments of calmness,were derived from the literature and confirmed through a concept story.A definition of the concept integrating the core qualities was formed:overcoming exhaustion involves realizing moments of calmness amidst despair.A model was created to demonstrate the relationship between core qualities,despair,and moments of calmness.Conclusions:The concept of overcoming exhaustion was developed and,through the concept-building process,was defined as realizing moments of calmness amidst despair.By identifying the complexities of overcoming exhaustion,this work lays the foundation for a future research program to develop understanding and interventions that support nurse well-being in the context of ongoing personal and professional demands.

文摘By analyzing the structure and academic characteristics of early Western Han medical texts such as Prescriptions for Fifty-Two Diseases(Wu Shi Er Bing Fang)and Prescriptions for Health Preservation(Yang Sheng Fang),and considering the development of philosophical thinking during the pre-Qin and Han periods,this study summarizes how Zhongjing Zhang’s Treatise on Cold Damage and Miscellaneous Diseases(Shang Han Za Bing Lun)inherited pre-Qin and Han philosophical thought while further integrating Daoist“natural law”cosmology,Confucian“benevolence”social ethics,and the“isomorphic unity of heaven and humanity”medical theory in Yellow Emperor’s Inner Classic(Huang Di Nei Jing).It proposes health preservation concepts encompassing heaven-human,body-spirit,and benevolence perspectives,along with dietary hygiene,representing the medical embodiment of pre-Han“virtue cultivation”and“body nurturing”life philosophies that profoundly influenced subsequent traditional Chinese medicine health preservation theory and practice.

文摘To define the concept of humanistic quality of nurses by Rodgers’evolutionary conceptual analysis.Based on Rodgers’s evolutionary concept analysis method as the theoretical basis to analyze the concept of humanistic literacy of nurses,the databases of CNKI,Wanfang,VIP,PubMed,Web of Science,and Science Direct were searched systematically from October 31st,2024.According to the inclusion and exclusion criteria,43 literatures were selected,including 34 Chinese literatures and 9 English literatures.Nurses’humanistic quality involved five conceptual attributes,including ethics,legal knowledge,traditional culture,interpersonal interaction,and aesthetic accomplishment.Antecedent variables include education environment,growth environment,hospital environment,and professional identity,and the consequences are divided into positive and negative aspects.Among them,positive consequences include harmonious nurse-patient relationships,efficient communication and cooperation,and improved nursing quality,while negative consequences include poor hospital operation,nurse-patient disputes,and reduced work quality.This paper defines and analyzes the humanistic qualities of nurses through the conceptual analysis of Rogers’theory of evolution,and the humanistic qualities of nurses refer to the comprehensive qualities of nurses based on ethics,legal knowledge,traditional culture,interpersonal interactions,and aesthetics in their professional practice,which will serve as a reference for future research in related fields.

文摘Conventional open-loop deep brain stimulation(DBS)systems with fixed parameters fail to accommodate interindividual pathological differences in Parkinson's disease(PD)management while potentially inducing adverse effects and causing excessive energy consumption.In this paper,we present an adaptive closed-loop framework integrating a Yogi-optimized proportional–integral–derivative neural network(Yogi-PIDNN)controller.The Yogi-augmented gradient adaptation mechanism accelerates the convergence of general PIDNN controllers in high-dimensional nonlinear control systems while reducing control energy usage.In addition,a system identification method establishes input–output dynamics for pre-training stimulation waveforms,bypassing real-time parameter-tuning constraints and thereby enhancing closed-loop adaptability.Finally,a theoretical analysis based on Lyapunov stability criteria establishes a sufficient condition for closed-loop stability within the identified model.Computational validations demonstrate that our approach restores thalamic relay reliability while reducing energy consumption by(81.0±0.7)%across multi-frequency tests.This study advances adaptive neuromodulation by synergizing data-driven pre-training with stability-guaranteed real-time control,offering a novel framework for energy-efficient and personalized Parkinson's therapy.
