ابرتقارن دینامیکی در فیزیک هسته ای در زمینه ی مدل اندرکنشی بوزونی (ibm) و توسعه آن معرفی میگردد. ibm تحریک جمعی در هسته های زوج-زوج را در جمله هایی از یک سیستم اندرکنشی بوزونی تک قطبی (s^†) و چهارقطبی (d^†) بیان میکند. که روی هم میتوان بوسیله ی b_i^† با تکانه زاویه ای l=0,2 نوشت. بوزونها به تعداد جفت پروتون و نوترون همبسته مربوط میشوند و بدین دلیل تعداد بوزونها ،n، نصف تعداد نوکلئونهای ظرفیت می...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
IBM ProbE (for probabilistic estimation) is an extensible, embeddable, and scalable modeling engine, particularly well-suited for implementing segmentation-based modeling techniques, wherein data records are partitioned into segments and separate predictive models are developed for each segment. We describe the ProbE framework and discuss two key business solutions that have been built using Pr...
Phrase level translation models are effective in improving translation quality by addressing the problem of local re-ordering across language boundaries. Methods that attempt to fundamentally modify the traditional IBM translation model to incorporate phrases typically do so at a prohibitive computational cost. We present a technique that begins with improved IBM models to create phrase level k...
Individual-based models (IBMs) of human populations capture spatio-temporal dynamics using rules that govern the birth, behavior, and death of individuals. We explore a stochastic IBM of logistic growth-diffusion with constant time steps and independent, simultaneous actions of birth, death, and movement that approaches the Fisher-Kolmogorov model in the continuum limit. This model is well-suit...
Degenerative mechanisms such as protein accumulation and vacuolar transformation in the skeletal muscle distinguish inclusion body myositis (IBM) from other inflammatory myopathies. IBM is particularly common in patients over the age of 50 years and inevitably leads to progressive muscle weakness and atrophy. Conventional immunotherapies, albeit effective in other forms of myositis, seem to hav...
We derive a hierarchy of kinetic and macroscopic models from a noisy variant of the heuristic behavioral Individual-Based Model of [53] where the pedestrians are supposed to have constant speeds. This IBM supposes that the pedestrians seek the best compromise between navigation towards their target and collisions
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
