Shared early processing of distinct tactile features [PDF]

open access: yesiScience
Summary: The extent to which spatial tactile properties share neural pathways remains unclear, yet it is the key to understanding how the brain constructs coherent object representations from distributed spatial inputs.

How to empower Grünwald–Letnikov fractional difference equations with available initial condition?

open access: yesNonlinear Analysis, 2022
In this paper, the initial condition independence property of Grünwald–Letnikov fractional difference is revealed for the first time. For example, the solution x(k) of equation aG∇kαx(k) = f(x(k)),  k > a + 1, cannot be calculated with initial condition

On Expectation Correlate System and Chaotic Dynamics in Time-Series [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2004
This paper suggests a new system of time-series called  Expectation Correlate System (ECS) that are good at detecting the behavior of  dynamical  systems (both deterministic and stochastic systems) and the dependence on initial values.

Regular T_0 ‐type Separations in Fuzzy Topological Spaces in the Sense of Quasi‐coincidence [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2021
In this paper, we introduce and study three notions of  property in fuzzy topological spaces using quasi-coincidence sense, and we relate to other such notions. Then, we show that all these notions satisfy good extension property.

On the External Positivity of SISO Linear Dynamic Systems under a Class of Nonzero and Possibly Negative Initial Conditions Eventually Subject to Incommensurate Point Internal and External Delays

open access: yesSystems, 2022
The property of external positivity of dynamic systems is commonly defined as the non-negativity of the output for all time under zero initial conditions and any given non-negative input for all time.
