the breakdown of the adiabaticity in the stationary nonstationary chaos Transition Process
Journal of Physics: Conference Series, 2006Co-Authors: Takuma Akimoto, Yoji AizawaAbstract:The logarithmic scaling regime is often generated in the dynamical Processes of the stationary-nonstationary chaos Transition, where the breakdown of the adiabaticity plays an essential role. We obtained the analytical criterion for the onset time of the non-adiabaticity carrying out with a typical non-hyperbolic chaotic system.

weibull and log weibull laws in the stationary nonstationary chaos Transition Process a phenomenological model of the aftershock statistics in seismology
Progress of Theoretical Physics Supplement, 2006Co-Authors: Takuma Akimoto, Yoji AizawaAbstract:The statistical features of the large fluctuations in the model of the aftershock phenomenon are studied in terms of the stationary-nonstationary chaos Transition Process. We demonstrate that the cross-over phenomena from Weibull to Log-Weibull distributions for the waiting time of the largest deviation are clearly observed in the logarithmic scaling regime.

Logarithmic Scaling in the Stationary-Nonstationary Chaos Transition
Progress of Theoretical Physics, 2003Co-Authors: Takuma Akimoto, Yoji AizawaAbstract:Statistical features of the Transition Process from stationary to nonstationary chaos are studied using modified Bernoulli maps. The stationary-nonstationary chaos Transition Process can be generated by varying the value of the parameter that controls the intensity of the intermittency. The measure-theoretical structures of the chaos Transition Process are significantly different from the time-independent case, and new statistical phenomena appear, even when the value of the system parameter is changed continuously in time. The temporal behavior of the Transition Process is generally separated into three characteristic phases. The first phase appears in the initial stage of the Transition, and the third one in the last stage, where the Transition is almost finished, but the most interesting phase is the second one, which continues for long period. The entire Transition Process is analyzed using the renewal function, which describes the temporal behavior of the mean accumulated number of intermittent jumps. The logarithmic scaling relation appearing in the second phase is studied in detail with finite-range statistics. Finally, the statistical laws of the stationary-nonstationary chaos Transition are discussed from the viewpoint of the modeling of seismological phenomena, and it is shown that seismological data are accounted for quite well by a metaphor model in terms of the stationary-nonstationary chaos Transition.

us adult rheumatologists perspectives on the Transition Process for young adults with rheumatic conditions
Arthritis Care and Research, 2020Co-Authors: Devy Zisman, Aaida Samad, Stacy P Ardoin, Peter Chira, Patience H White, Idit Lavi, Emily Von Scheven, Erica F Lawson, Melinda Hing, Elizabeth D MellinsAbstract:OBJECTIVE To assess the attitudes and common practices of adult rheumatologists in the US regarding health care Transition (HCT) for young adults with rheumatic diseases. METHODS An anonymous online survey was sent to US adult rheumatologist members of the American College of Rheumatology to collect demographic data and information on attitudes and common practices regarding the Transition Process. RESULTS Of 4,064 contacted rheumatologists, 203 (5%) completed the survey. Almost half of respondents (45.1%) were never trained in Transition practices, and 74.7% were not familiar with the American Academy of Pediatrics/American Academy of Family Physicians/American College of Physicians Consensus Statement About Transitions for Youth with Special Healthcare Needs. Only 56.2% felt comfortable caring for former pediatric patients. The vast majority of respondents (90.7%) did not have a multidisciplinary Transition team, and 37% did not have a plan for Transitioning pediatric patients into their practice. Most adult rheumatologists were unsatisfied with the current Transition Process (92.9%), due to insufficient resources, personnel (91.1%), and time in clinic (86.9%). They also were unsatisfied with referral data received concerning previous treatments (48.9%), hospitalization history (48%), disease activity index (45.1%), medical history summary (43.9%), comorbidities (36.4%), medication list (34.1%), and disease classification (32.6%). Three major barriers to HCT were lack of insurance reimbursement (33.7%), knowledge about community resources (30.8%), and lapses in care between primary provider and specialist (27.8%). CONCLUSION This survey identified substantial gaps in knowledge and resources regarding HCT for young adults with rheumatic diseases. These may be best addressed by further training, research, dedicated resources, adequate payment, and practice guidelines.

the occupational Transition Process to upper secondary school further education and or work in sweden as described by young adults with asperger syndrome and attention deficit hyperactivity disorder
Journal of Autism and Developmental Disorders, 2017Co-Authors: Vedrana Bolic Baric, Helena Hemmingsson, Kristina Hellberg, Anette KjellbergAbstract:The aim was to describe the occupational Transition Process to upper secondary school, further education and/or work, and to discover what support influences the Process from the perspectives of young adults with Asperger syndrome or attention deficit/hyperactivity disorder. This qualitative study was performed in Sweden and comprised interviews with 15 young adults recruited from community based day centres. Support influencing the Process included: occupational Transition preparation in compulsory school, practical work experience in a safe environment, and support beyond the workplace. The overall understanding shows that the occupational Transition Process was a longitudinal one starting as early as in middle school, and continuing until the young adults obtained and were able to remain in employment or further education.
