Enhancing the resolution of sparse rock property measurements using machine learning and random field theory

The travel time of rock compressional waves is an essential parameter used for estimating important rock properties,such as porosity,permeability,and lithology.Current methods,like wireline logging tests,provide broad measurements but lack finer resolution.Laboratory-based rock core measurements offer higher resolution but are resource-intensive.Conventionally,wireline logging and rock core measurements have been used independently.This study introduces a novel approach that integrates both data sources.The method leverages the detailed features from limited core data to enhance the resolution of wireline logging data.By combining machine learning with random field theory,the method allows for probabilistic predictions in regions with sparse data sampling.In this framework,12 parameters from wireline tests are used to predict trends in rock core data.The residuals are modeled using random field theory.The outcomes are high-resolution predictions that combine both the predicted trend and the probabilistic realizations of the residual.By utilizing unconditional and conditional random field theories,this method enables unconditional and conditional simulations of the underlying high-resolution rock compressional wave travel time profile and provides uncertainty estimates.This integrated approach optimizes the use of existing core and logging data.Its applicability is confirmed in an oil project in West China.

Using Poisson Modeling and Queuing Theory to Optimize Staffing and Decrease Patient Wait Time in the Emergency Department

Introduction: Studies have shown Emergency Department (ED) crowding contributes to reduced quality of patient care, delays in starting treatments, and increased number of patients leaving without being seen. This analysis shows how to theoretically and optimally align staffing to demand. Methods: The ED value stream was identified and mapped. Patients were stratified into three resource-driven care flow cells based on the severity indices. Time observations were conducted for each of the key care team members and the manual cycle times and service rate were calculated and stratified by severity indices. Using X32 Healthcare’s Online Staffing Optimization (OSO) tool, staffing inefficiencies were identified and an optimal schedule was created for each provider group. Results: Lower Severity Indices (higher acuity patient) led to longer times for providers, nurses, patient care assistants, and clerks. The patient length of stay varied from under one hour to over five hours. The flow of patients varied considerably over the 24 hours’ period but was similar by day of the week. Using flow data, we showed that we needed more nurses, more care team members during peak times of patient flow. Eight hour shifts would allow better flexibility. We showed that the additional salary hours added to the budget would be made up for by increased revenue recognized by decreasing the number of patients who leave without being seen. Conclusion: If implemented, these changes will improve ED flow by using lean tools and principles, ultimately leading to timeliness of care, reduced waits, and improved patient experience.

Afforestation increases microbial diversity in low-carbon soils

Afforestation has an important role in biodiversity conservation and ecosystem function improvement.A meta-analysis was carried out in China,which has the largest plantation area globally,to quantify the effects of plantings on soil microbial diversity.The results showed that the overall effect of afforestation on soil microbial diversity was positive across the country.Random forest algorithm suggested that soil carbon was the most important factor regulating microbial diversity and the positive response was only found with new plantings on low-carbon bare lands but not on high-carbon farmlands and grasslands.In addition,afforestation with broadleaved species increased microbial diversity,whereas planting with conifers had no effect on microbial diversity.This study clarified the effects of plantings on soil microbial diversity,which has an important implication for establishing appropriate policies and practices to improve the multiple functionalities(e.g.,biodiversity conservation and climate change mitigation)during plantation establishment.

A study on the psychological needs of nurses caring for patients with coronavirus disease 2019 from the perspective of the existence,relatedness, and growth theory

Objective:This study aimed to explore the psychological needs of nurses caring for patients with coronavirus disease 2019(COVID-19)and to propose corresponding interventions.Methods:In-depth interviews were conducted with 10 nurses who cared for patients with COVID-19.Interview data were analyzed by category analysis from the perspective of the existence,relatedness,and growth theory(ERG).Results:The existence needs were mainly reflected in health and security needs,whereas the relatedness needs consisting mainly of interpersonal needs,humanistic concern needs,and family needs;further,the growth needs were mainly reflected as a strong need for knowledge.Existence needs were the main needs during the epidemic,with health and security needs influencing each other.Humanistic concern needs were the most important of the relatedness needs;interpersonal and family needs were also growing.Conclusion:It is found that the existence,relatedness,and growth needs coexist in clinical nurses.It is helpful to take effective interventions to meet their needs if the needs of nurses caring for COVID-19 patients could be perceived well.

Ecological Remediation Measures for Non-point Source Pollution Based on Source-Sink Landscape Theory: A Case Study of Huanghou Basin

The growth of society and population has led to a range of water pollution issues.Among these,non-point source pollution assessment and treatment pose a particular challenge due to its formation mechanism.This has become a focal point and challenge in water pollution treatment research.The study area for this research was the Huanghou basin in Guizhou Province,southwest China.The land use type of the basin was analyzed using remote sensing technology,and water quality data was collected by distributing points throughout the basin,based on source-sink landscape theory.The distribution map of the basin’s source-sink landscape and the results of water quality data accurately and efficiently identified the areas with high risk of non-point source pollution in the western and southwestern residential and agricultural areas of the upper basin.Hence,a strategy of“increasing sinks and decreasing sources”was proposed.The strategy was implemented at both macro and micro levels to address non-point source pollution in the basin using ecological remediation techniques.The work to control karst rocky desertification should continue at a macro level.The rocky desertification area in the basin should gradually transform into grassland and forested land,while increasing the overall area of the sink landscape.Ecological restoration techniques,such as slope planting,riparian zone vegetation restoration,increasing plant abundance,and restoring aquatic plants,can effectively control non-point source pollution at the micro level.Compared to traditional control methods,this remediation strategy focuses on source and process control.It is more effective and does not require large-scale water pollution control projects,which can save a lot of environmental control funds and management costs.Therefore,it has greater research significance and application value.

Understanding the individual with Alzheimer’s disease: Can socioemotional selectivity theory guide us?

Individuals often get lost behind the diagnosis of Alzheimer’s disease (AD) while widespread differences between these patients are morecommon than similarities. Socioemotional Selectivity Theory (SST) suggests that as we age our goals change from future-oriented (acquiringnew information) to present-oriented (enhancing the emotional, especially positive, meaning of encounters). The goal of the current article is to examine whether the principles of SST might also apply for people with AD. Some aspects of SST are found especially in the early stages of AD when awareness is often intact and cognitive impairment is relatively limited. This review has clinical significance for the treatment of AD because it focuses on what is important to the individual rather than treating patients as a homogenous group. It also highlights the importance of social networks and emphasizes the role of the proxy in AD care. Lastly, it suggests that if those with AD (like the healthy elderly) have a positivity bias then positive emotional stimuli/wording/instructions could usefully be employed in their daily treatment. I suggest that SST may be a useful starting point when attempting to address what matters to individuals with AD and conclude by providing a few suggestions for future studies.

Acupuncture Treating Heart Disease Based on Eight Palaces or Eight Veins <br/>—Mathematical Reasoning of Treatment Principle Based on Yin Yang Wu Xing Theory in Traditional Chinese Medicine (IV)

Theory of eight palaces (八宫) or eight veins (八脉) is useful in understanding the basic sick subsystems that may be to fall ills as the root-cause. By using mathematical reasoning based on Yin Yang Wu Xing Theory in Traditional Chinese Medicine (TCM), this paper demonstrates the treatment principle: “Even if all changed, it is hard to change one’s nature” (江山易改, 本性难移). The eight palaces or eight veins can be used to diagnose basic sick subsystems that may be to fall ills as the root-cause. The first or second transfer law of human body energies of the eight palaces or eight veins according to the different blood pH values of a human body whether in the normal range or not, respectively, assuming that the range of blood pH value is divided into four parts from small to large. Both second and third are for a healthy human body. Both the root-cause and symptoms come from the first transfer law of human body energies. And both first and fourth are for an unhealthy human body. Both the root-cause and symptoms come from the second transfer law of human body energies. A disease treatment should protect and maintain the balance of two incompatibility relations: the loving relationship and the killing relationship. As an application, acupuncture is used to treat atrial premature beats as a congenital heart disease.

Conceptual Comparison of Infectious Diseases of TIBBE-AKBARI and Modern Medicine: Akhlat and Mezaj Theory

Background: Treating infectious diseases (ID) is the priority of health systems. Traditional Persian medicine (TPM) has diagnostic and preventive comments in most diseases. Readout TPM gives opportunity to know the viewpoints of ancient Iranian scholars for using these opinions in treating ID. In this regard returning to TPM options and modalities can be useful at least as complementary method in treating ID. For understanding the concepts of ID in TPM first of all it is needed to trace ID in TPM and translate them into western medicine language which is the goal of this report. Methodology: This research includes 80 ID mentioned in TIBBE-AKBARI (one of Persian Medicine textbook) for rewriting and comparing with conventional medicine findings. Findings: The majority of clinical signs, symptoms and physical examinations of ID are comparable with modern medicine except the viewpoint of TPM about aetiology which is based on Akhlat and Mezaj theory. By considering no option for antibiotic therapy in ancients time so there is a completely different opinion in treating ID with modern medicine. Conclusion: IDs have different names in TPM and conventional medicine. In contrast to modern medicine in which micro-organism are as etiologic agents, Akhlat and Mezaj theory of TPM has main role for description of ID, the subject which must to be decoded. Although they have completely different opinions in treatment, but with regard to the increasing of antibiotic resistance issue, TPM treatment comments may be useful in future in ID as complementary method beside antibiotics.

Game Theory-Based Dynamic Weighted Ensemble for Retinal Disease Classification

An automated retinal disease detection system has long been in exis-tence and it provides a safe,no-contact and cost-effective solution for detecting this disease.This paper presents a game theory-based dynamic weighted ensem-ble of a feature extraction-based machine learning model and a deep transfer learning model for automatic retinal disease detection.The feature extraction-based machine learning model uses Gaussian kernel-based fuzzy rough sets for reduction of features,and XGBoost classifier for the classification.The transfer learning model uses VGG16 or ResNet50 or Inception-ResNet-v2.A novel ensemble classifier based on the game theory approach is proposed for the fusion of the outputs of the transfer learning model and the XGBoost classifier model.The ensemble approach significantly improves the accuracy of retinal disease pre-diction and results in an excellent performance when compared to the individual deep learning and feature-based models.

Use of Social Cognitive Theory to Assess Salient Clinical Research in Chronic Disease Self-Management for Older Adults: An Integrative Review

The purpose of this integrative review is to evaluate research pertaining to self-management programs for older adults with chronic diseases using Albert Bandura’s Social Cognitive Theory (SCT) for behavior change. The focus is application of the SCT domains to self-management programs. The exploration of the current chronic disease self-management research provides an understanding of the Social Cognitive Theory concepts studied in interventional self-management research. The integrative review explicated two areas related to the theory in need of further research. First, social support has not been thoroughly explored as a mechanism for enhancing self-management interventions. Second, moral disengagement was not identified as a focus within chronic disease research raising the question about the impact of moral disengagement on long-term adherence and behavior change.

The relationship between the lymphatic system and Alzheimer's disease wasdiscussed based on the tri-jiao theory

Type of the lymphatic system is a new concept put forward by foreign scholars in recent years.It is similar to the lymphatic system,is the brain of the internal fluid metabolism channel and its metabolites in the brain plays a major role in the process of removal,sleep disorders in alzheimer's disease brain stroke,traumatic brain injury and other central nervous system diseases.The Tri-jiao theory is a very important in traditional Chinese medicine plate structure,it is from the function to traffic from running water channel,but still no definite conclusion on structure.This paper attempts to explore the relationship between trioke and the lymphatic system and their influence on Alzheimer's disease through modern medical research on the lymphatic system,so as to provide new inspirations for the treatment of Alzheimer's disease.

Acupuncture Treating Heart Diseases Based on Sixty JiaZi and Eight Palaces <br/>—Mathematical Reasoning of Treatment Principle Based on Yin Yang Wu Xing Theory in Traditional Chinese Medicine (V)

Theory of Sixty JiaZi (60 甲子) is useful in understanding a human body disease. By using mathematical reasoning based on Yin Yang Wu Xing Theory in Traditional Chinese Medicine (TCM), this paper demonstrates the treatment principle: “seize the momentum of development, hasten lucky avoids disaster” (顺势而为, 趋吉避凶). Sixty JiaZi is hidden behind eight palaces. The first or second transfer law of human body energies of Sixty JiaZi changes according to the different blood pH values of a human body whether in the normal range or not, respectively, assuming that the range of blood pH values of a human body is divided into four parts from small to large. Both second and third are for a healthy human body. Both the root-cause and symptoms come from the first transfer law of human body energies. And both first and fourth are for an unhealthy human body. Both the root-cause and symptoms come from the second transfer law of human body energies. The treating disease of a human body should protect and maintain the balance of two incompatibility relations: the loving relationship and the killing relationship. As an application, acupuncture is used to treat atrial premature beats as congenital heart disease.

Application of Preventive Treatment Theory in the Treatment of Pelvic Inflammatory Disease

With a history of more than two thousand years, the theory of preventative treatment has been closely followed by the development of modern medical theories on the basis of inheritance by medical experts in the past dynasties, which has been constantly improved and enriched, and deeply applied in the prevention and treatment of serious and multiple diseases. It has achieved great benefits. For women with gynecological diseases, pelvic inflammatory disease patients accounted for a large proportion. Due to the lack of specificity in diagnosis and treatment, the condition is lingering and difficult to cure, so it seriously reduces the quality of life of women, thus affecting the harmony of family and society. From the perspective of prevention, according to the characteristics of each stage of the disease, this paper put forward substantive prevention suggestions and targeted treatment methods, ensuring preventing before disease, preventing progress after disease, and preventing reoccurring after recovery. It has important practical significance for the prevention and treatment of pelvic inflammatory diseases, as well as the development and inheritance of traditional Chinese medicine.

Differentiating and Treating Gynecological Diseases based on the Theory of Collateral Diseases

The collateral disease theory is a unique component of the theoretical system of traditional Chinese medicine(TCM),which is currently applied to all kinds of diseases related to the collaterals.With the in-depth study of collaterals theory by many practitioners,its advantages in differentiating and treating gynecological diseases are gradually embodied.Based on the theory of collaterals disease,we discussed the pathogenesis,syndrome differentiation and treatment of gynecological diseases,concluded that the deficient collaterals under nourishment and the stagnant and blocked uterine collateral are the important pathogenesis of gynecological illness.Then we pointed out that invigorating the spleen and tonifying the kidney,and unblocking collateral and dissipating stasis are important treatment methods.We discussed the application of collateral disease theory in Tianjin HA's gynecology,and provided certain theoretical basis and clinical reference for the treatment of gynecologic diseases.
