Recent advances in the temporal and spatiotemporal dynamics induced by bromate–sulfite-based pH-oscillators

چکیده
Abstract The bromate–sulfite reaction-based pH-oscillators represent one of the most useful subgroup among chemical oscillators. They provide strong H + -pulses which can generate temporal oscillations in other systems coupled to them and they show wide variety spatiotemporal dynamics when are carried out different gel reactors. Some examples discussed. When pH-dependent physical processes linked a bromate–sulfite-based oscillator, rhythmic changes appear concentration some cations anions, distribution species pH-sensitive stepwise complex formation, oxidation number central cation chelate complex, volume or desorption-adsorption ability piece gel. These reactions quite suitable for generating patterns open Many reaction–diffusion phenomena, moving stationary patterns, have been recently observed experimentally using reactor configurations, allow exploring effect initial boundary conditions. Here, we summarize relevant aspects these experimental numerical studies on systems.

Spatial and Spatiotemporal Data Mining: Recent Advances
Explosive growth in geospatial data and the emergence of new spatial technologies emphasize the need for automated discovery of spatial knowledge. Spatial data mining is the process of discovering interesting and previously unknown, but potentially useful patterns from large spatial databases. The complexity of spatial data and intrinsic spatial relationships limits the usefulness of convention...

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Recent Advances in Hemophilia Gene Therapy
Heterogeneous loss of function mutations at F8 and F9 genes causes X-linked recessive bleeding disorders, hemophilia A (HA) and hemophilia B (HB), respectively. HA is clinically indistinguishable from HB and accounts for more than 80% of hemophilia cases; the former affects 1/5000 and the latter 1/25000 male births worldwide. In Iran, it is estimated that around 4300 HA and 900 HB patients are ...
متن کاملConsiderations and Recent Advances in Molecular Dynamics
Molecular dynamics simulations were first proposed in the 1950-60s as a method to study the motions of atoms at the molecular level. Today, the most prominent use of molecular dynamics is the study of biological molecules and materials science. Molecular dynamics is the study of the motions of atoms and molecules by numerically simulating Newtonian dynamics. Since computers are discrete, they m...
