Collision Prevention In Operation-Synchronized Simulations Using Dynamic Prescheduling Of Simulation Parameters
The increasing use of simulation technologies, especially virtual commissioning, in the context of modern plant development for manufacturing discrete parts is driven by the pressure to shorten time-to-market cycles and overcome supply bottlenecks. The need for robust technologies to seamlessly integrate the digital and physical world is growing as machine data becomes more readily available. A challenge to this integration is presented by the need to continuously adjust the movement parameters, especially for event-discrete actuators based on live data, taking wear, ageing and process-time fluctuations into account. A lack of synchronization leads to discrepancies between the simulation and reality renders them useless. Related works in this field are discussed, which highlight the complexities of achieving synchronization between simulation and reality, particularly in event-discrete signals and systems. The aim of this article is to present a method for reusing virtual commissioning models for operation-synchronized simulations at actuator level. This approach includes introducing of a methodology called prescheduling in order to compensate process uncertainties and also defines the necessary requirements for the simulation tool and model. The method is validated using an industrial test system and a commercial virtual commissioning tool to confirm its suitability for real-life implementation in industrial plants, which suggests its suitability for improving production efficiency and reducing costs by means of machine monitoring and proactive control interventions
Systematic Review on Mentalization as Key Factor in Psychotherapy
Background: Mentalization processes seem to be of high relevance for social learning and seem important in all psychotherapies. The exact role of mentalization processes in psychotherapy is still unknown. The aim of the present systematic review is to investigate whether mentalization is related to the therapeutic outcome and, if so, whether it has a moderating, mediative, or predictive function. Method: A systematic review with an electronic database search was conducted. A total of 2567 records were identified, and 10 studies were included in the final synthesis. Results: Psychotherapy research is still in an initial phase of examining and understanding the impact of mentalization on psychotherapy outcome. The small number of studies and the executed study designs and statistical analyses indicate the possible role that mentalization has in psychotherapy. Conclusion: Generally, strongly elaborated study designs are needed to identify the role of mentalization in psychotherapy. Mentalization seems to be differently represented in differential treatment approaches. Nevertheless, it should be noted that the patientâs mentalizing capacity seems to be relevant to the psychotherapy process. Psychotherapies should be adapted to this
Combined morphological and functional liver MRI using spin-lattice relaxation in the rotating frame (T1Ï) in conjunction with Gadoxetic Acid-enhanced MRI
Abstract Noninvasive early detection of liver cirrhosis and fibrosis is essential for management and therapy. The aim was to investigated whether a combination of the functional parameter relative enhancement (RE) on Gadoxetic Acid magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI) and the fibrosis parameter T1Ï distinguishes cirrhosis and healthy liver. We analyzed patients with Gd-EOB-DTPA-enhanced MRI and T1Ï mapping. Signal intensity was measured before and after contrast; RE was calculated. T1Ï was measured with circular regions of interest (T1Ï-cROI). A quotient of RE and T1Ï-cROI was calculated: the fibrosis function quotient (FFQ). Cirrhosis was evaluated based on morphology and secondary changes. 213 datasets were included. The difference between cirrhotic and noncirrhotic liver was 51.11âms vs. 47.56âms for T1Ï-cROI (pâ<â0.001), 0.59 vs. 0.70 for RE (pâ<â0.001), and 89.53 vs. 70.83 for FFQ (pâ<â0.001). T1Ï-cROI correlated with RE, râ=ââ0.14 (pâ<â0.05). RE had an AUC of 0.73. The largest AUC had the FFQ with 0.79. The best cutoff value was 48.34âms for T1Ï-cROI, 0.70 for RE and 78.59âms for FFQ. In conclusion T1Ï and RE can distinguish between cirrhotic and noncirrhotic liver. The FFQ, which is the combination of the two, improves diagnostic performance
Incidence and risk factors of mental disorders in the elderly: The European MentDis_ICF65+ study
Objective: While incidence rates of depression and anxiety disorders in the elderly have been comprehensively investigated, the incidence rates of other mental disorders have rarely been researched. The incidence rate and predictors of various mental disorders in the elderly were evaluated in different European and associated countries.
Methods: A cross-sectional and longitudinal multi-centre survey of Diagnostic and Statistical Manual of Mental Disorders (4th ed.) diagnoses was conducted in different European and associated countries (Germany, Italy, Spain, Switzerland, the United Kingdom and Israel) to collect data on the prevalence and incidence of mental disorders in the elderly. The sample size of the longitudinal wave was N = 2592 elderly.
Results: The overall 1-year incidence rate for any mental disorder in the elderly is 8.65%. At 5.18%, any anxiety disorder had the highest incidence rate across all diagnostic groups. The incidence rate for any affective disorder was 2.97%. The lowest incidence rates were found for agoraphobia (1.37%) and panic disorder (1.30%). Risk factors for the development of any mental disorder were never having been married, no religious affiliation, a higher number of physical illnesses and a lower quality of life.
Conclusion: In comparison to other studies, lower incidence rates for any affective disorder and middle-range incidence for any anxiety disorder were found. To the authors' knowledge, no prior studies have reported 1-year incidence rates for somatoform disorder, bipolar disorder and substance misuse in community-dwelling elderly. These findings indicate the need to raise awareness of psychosocial problems in the elderly and to ensure adequate availability of mental health services
