Diagnostic Ultrasound Induced Inertial Cavitation To Non-Invasively Restore Coronary And Microvascular Flow In Acute Myocardial Infarction [PDF]

, 2013
Ultrasound induced cavitation has been explored as a method of dissolving intravascular and microvascular thrombi in acute myocardial infarction. The purpose of this study was to determine the type of cavitation required for success, and whether longer ...

Adaptive Pinning Synchronization of Fractional Complex Networks with Impulses and Reaction–Diffusion Terms

Mathematics, 2019
In this paper, a class of fractional complex networks with impulses and reaction−diffusion terms is introduced and studied. Meanwhile, a class of more general network structures is considered, which consists of an instant communication topology and

Existence and Integral Representation of Scalar Riemann-Liouville Fractional Differential Equations with Delays and Impulses

Mathematics, 2020
Nonlinear scalar Riemann-Liouville fractional differential equations with a constant delay and impulses are studied and initial conditions and impulsive conditions are set up in an appropriate way.

Formulation of Impulsive Ecological Systems Using the Conformable Calculus Approach: Qualitative Analysis

Mathematics, 2023
In this paper, an impulsive conformable fractional Lotka–Volterra model with dispersion is introduced. Since the concept of conformable derivatives avoids some limitations of the classical fractional-order derivatives, it is more suitable for applied ...

Controllability Criteria for Nonlinear Impulsive Fractional Differential Systems with Distributed Delays in Controls

Mathematical and Computational Applications, 2023
We establish a class of nonlinear fractional differential systems with distributed time delays in the controls and impulse effects. We discuss the controllability criteria for both linear and nonlinear systems.

Sharp Alfvénic Impulses in the Near-Sun Solar Wind

Astrophysical Journal Supplement Series, 2019
Measurements of the near-Sun solar wind by the Parker Solar Probe have revealed the presence of large numbers of discrete Alfvénic impulses with an anti-sunward sense of propagation. These are similar to those previously observed near 1 au, in high speed

The Archival Impulse and the Editorial Impulse [PDF]

Variants, 2019
There is no firm, outside vantage-point from which to survey and thus to define archive and edition as securely differentiated categories. As readers we inhabit the same textual field as the approaches to documents and texts that we seek to define. To record is first to read and analyse sufficiently for the archival purpose; to interpret is first to ...
