Automatic Generation of Attribute-Based Access Control Policies from Natural Language Documents

In response to the challenges of generating Attribute-Based Access Control(ABAC)policies,this paper proposes a deep learning-based method to automatically generate ABAC policies from natural language documents.This method is aimed at organizations such as companies and schools that are transitioning from traditional access control models to the ABAC model.The manual retrieval and analysis involved in this transition are inefficient,prone to errors,and costly.Most organizations have high-level specifications defined for security policies that include a set of access control policies,which often exist in the form of natural language documents.Utilizing this rich source of information,our method effectively identifies and extracts the necessary attributes and rules for access control from natural language documents,thereby constructing and optimizing access control policies.This work transforms the problem of policy automation generation into two tasks:extraction of access control statements andmining of access control attributes.First,the Chat General Language Model(ChatGLM)isemployed to extract access control-related statements from a wide range of natural language documents by constructing unique prompts and leveraging the model’s In-Context Learning to contextualize the statements.Then,the Iterated Dilated-Convolutions-Conditional Random Field(ID-CNN-CRF)model is used to annotate access control attributes within these extracted statements,including subject attributes,object attributes,and action attributes,thus reassembling new access control policies.Experimental results show that our method,compared to baseline methods,achieved the highest F1 score of 0.961,confirming the model’s effectiveness and accuracy.

Optimizing risk management for post-amputation wound complications in diabetic patients: Focus on glycemic and immunosuppressive control

This study highlights the importance of identifying and addressing risk factors associated with wound complications following transtibial amputation in diabetic patients.These amputations,often necessitated by severe diabetic foot ulcers,carry significant risks of postoperative complications such as infection and delayed wound healing.Elevated hemoglobin A1c levels,indicative of poor glycemic control,and a history of kidney transplantation,due to required immunosuppressive therapy,are key factors influencing these outcomes.This paper emphasizes the need for enhanced glycemic management and personalized postoperative care,particularly for immunocompromised individuals,to minimize complications and improve patient prognosis.Future research should focus on prospective studies to validate targeted interventions and optimize care strategies,ultimately aiming to reduce the healthcare burden associated with diabetic foot complications.

Extraction of Robot Primitive Control Rules from Natural Language Instructions

A support vector rule based method is investigated for the construction of motion controllers via natural language training. It is a two-phase process including motion control information collection from natural language instructions, and motion information condensation with the aid of support vector machine （SVM） theory. Self-organizing fuzzy neural networks are utilized for the collection of control rules, from which support vector rules are extracted to form a final controller to achieve any given control accuracy. In this way, the number of control rules is reduced, and the structure of the controller tidied, making a controller constructed using natural language training more appropriate in practice, and providing a fundamental rule base for high-level robot behavior control. Simulations and experiments on a wheeled robot are carried out to illustrate the effectiveness of the method.

Language Neuromechanics: The Human Biological-Language Evolution

The paper proposes that the understanding of human language evolution requires the comprehensive understanding of language in terms of language types, formations, and learnings and the comprehensive understanding of human biological evolution in terms of the emergences of various hominin species with various language capacities. This paper proposes language neuromechanics and the human biological-language evolution. Language is derived from bodily movement. Language neuro-mechanics combines neuroscience to study language brain and biomechanics to study language movement. Language neuromechanics consists of language type, language formation, and language learning. Language types for advanced animals include gestural language verse vocal language, instinctive language verse controllable language, and symbolic language verse iconic language. Language formation involves the developments of the different types of languages from different bodily movements phylogenetically and ontogenetically. Language learning involves the learning of controllable language to adapt to communicative environment through language brain regions and language genes. This paper proposes a gradual and step-by-step human language evolution from the language of great apes to the human language through the human biological evolution which chronologically and geographically consists of early hominins, early Homos, middle Homos, and late Homos with different language capacities. For hominins, vocal language and gestural language were evolved together. In conclusion, combining neuroscience and bio-mechanics, language neuromechanics provides the comprehensive understanding of language. The combination of language neuromechanics and the human biological-language evolution provides the clear evolutionary path from great apes’ articulate gestural language without articulate speech to human articulate gestural language and articulate speech.

Performance-Associated Factors of Elderly Patients with a Low Education Level, with Acquired Language Alterations in Tests to Explore Executive Functions

Introduction. Secondary alterations of executive functions occur in brain injuries together with the primary neuropsychological symptoms, irrespective of the location of the damage and the affected neural networks. Such secondary alterations of executive functions in the presence of language alterations, which is the most frequent primary neuropsychological alteration, in addition to exacerbating the linguistic processing deficit, may be associated to multiple factors inherent to the brain injury or the injured patient. Purpose. To describe the secondary neuropsychological alterations of executive functions in elderly patients with low education levels with acquired language disorders and determine general factors of the injury and of the injured patient (etiology, location, time of recovery from the injury, age, education level), associated to such secondary alterations of the Attentional Control System. Patients and Methods. The study was conducted on 68 elderly patients with a low education level with language acquired disorders, of both sexes, ranging between 60 and 80 years of age. The executive functions explored included cognitive flexibility, impulsivity control and inhibition of irrelevant automatisms, with the Trail Making Test, the Porteus Maze Test and series of loops. Statistical processing involved a Distribution of Frequencies and Multiple Ordinal Regression. Results and Conclusions. The statistical analysis found secondary neuropsychological alterations of the executive functioning in the elderly patients with language disorders of the study that are associated to the location and the time of recovery from the injury and are irrespective of age, education level and etiology of the injury.
