My name is Amin and I am an Acting Instructor in Applied Math at University of Washington. Below I briefly outline my research and teaching.
According
to the National Cancer Institute, almost 40% of men and women in the
United States end up developing cancer in their lifetime, and total
national expenditure on cancer is $125 Billion. While cancer
deaths have fallen, the treatment of cancer is still predominant a trial
and error process. This may result in delays to administer the
correct treatment, the use of more invasive procedures, or an increase
in toxicity due to superfluous treatments. Although these
procedures may end up saving the patient, the treatment may also have an
adverse effect on their quality of life. To remedy this cruel
paradox my collaborators and I have been developing a framework of
complete scientific investigations for optimal treatment through the use
of robust mathematical models and biological experiments rooted in the
rigors of physics.
Once again, borrowing statistics from the National Cancer Institute, over 60% of cancer
cases and over 70% of cancer related deaths occur in Africa,
Asia, and South America, having the worst effect on the poorest
populations. Some of the easiest cancers to treat in the Western
world, solid  accessible tumors, are often fatal in poor
nations. In industrialized nations the answers to solid tumors is
simple  operate. However, operation is generally quite complex,
and costs a significant amount of money. This can be remedied by
the use of drug injections into solid tumors, which is cheap and does
not require much skill. We have developed mechanistic models for
the fluidic interactions of the drug with the geometry and topography of
the tumor coupled with statistical models of drug response for a
population in order to achieve high predictive capabilities and show
causality. In oncological studies the data is represented by
doseresponse curves, which we also have from our model, however having a
model also gives us the ability to plot dosetimeresponse surfaces,
which
gives us a more finegrained picture for the effects of the drug.

It
has been known for decades that, given proper conditions, a fluid drop
can be made to bounce on a vibrating fluid bath for long times
scales. In recent years, bouncing droplets have been observed to
bifurcation from the bouncing state (no horizontal motion) to the
walking state (horizontal motion). Experiments with walking
droplets (called walkers) exhibit analogs of waveparticle
duality and more specifically quantumlike phenomena. Studying
walkers can enhance our understanding of quantum mechanics and suggest viable alternatives to the Copenhagen interpretation.
My research has focused on attacking walking dynamics on two fronts: developing simple models for various geometries
and analyzing well established models via dynamical systems
theory. Recently, this has manifested in modeling multiple non
chaotic walkers and single chaotic walkers in an annulus, proving the
existence of various bifurcations and chaotic dynamics for my models.
and analyzing novel bifurcations arising in models from previous
investigations.

Logical
circuits are an integral part of modern life that are traditionally
designed with minimal uncertainty. While this is straightforward
to achieve with electronic logic, other logic families such as fluidic,
chemical, and biological circuits naturally exhibit uncertainties due to
the slower timescales of Boolean operations. In addition, chaotic
logical circuits have the potential to be employed in random number
generation, encryption, and fault tolerance. However, in order to
exploit the properties of various nonlinear circuits they need to be
studied further. Since experiments with large systems become
difficult, tractable mathematical models that are amenable to analysis
via dynamical systems theory are of particular value.
We developed a modeling framework for the chaotic Set/Reset flipflop
circuit and two types of chaotic NOR gates. Through this
framework we derive discrete dynamical models for Set/Reset  type
circuits with any number of NOR gates. Since the models are
recurrence relations, the computational expense is quite low.
Further, we conducted experiments to test these models, which shows both
qualitatively and quantitatively close behavior between the theory and
experiments.

Upon discovering a new global bifurcation in discrete dynamical
models of walking droplets, we developed a generic dynamical system in
order to generalize the theory of such bifurcations. From a
graphical point of view, the invariant circle from an initial
NeimarkSacker bifurcation "blinks" on and off. This is due to
the transition from tangential to transverse intersections of the
unstable and stable manifolds of the saddle fixed point.

We had previously shown that attracting horseshoes may be generalized to be contained within a quadrilateral trapping region. Through the NJIT Provost high school internship and the
Provost Phase 1 undergraduate research grant, I mentored Karthik murthy
(Bridgewater  Raritan High School) and Parth Sojitra (NJITECE), under
the supervision of Denis Blackmore, in finding numerical evidence of
generalized attracting horseshoes (GAH) in Poincare maps of the Rossler
attractor. I developed the algorithms to go from a first return
map to a Poincare map and finally to find the quadrilateral trapping
region for the supposed GAH. I then guided our students in writing
the MATLAB codes to carry out the algorithms. While finding the
trapping region numerically is not a proof, it does give us confidence
that there exists a GAH in the Poincare map of the Rossler attractor.

Chaotic scattering has been studied from the early 70s and
80s in solitary wave collisions from the PhiFour equation (called KinkAntikink
collisions). These were mainly numerical studies that
gave insight into the phenomena. However, since the
equation is so difficult to work with there has been very
little analysis done. In more recent years reduction
techniques have been used to approximate the PhiFour PDE
with a system of ODEs and also as an iterated map.
We have gone further and developed a mechanical analog (a
ball rolling on a special surface) of chaotic scattering in
KinkAntikink collisions. This was done in order to
conduct experiments. In addition to experiments we
have analyzed the system thoroughly, including the
dissipation that comes from friction. The experimental setup is
shown bellow.

Peixoto's theorem is one of the most important theorems in Dynamical Systems. It was proved by Dr. Mauricio Matos Peixoto in 1962. This proof is extremely involved  far too involved for most undergraduate students to follow. We develop an alternate  pedagogical proof of the simpler 1D case, with the goal of allowing senior undergraduate students to follow and understand the proof and consequently some of the ideas involved in the much bigger proof of the 2D case.

We numerically simulate the beam dynamics of the Energy Recovery Linear Particle Accelerator (ERL) design for Argonne National Lab's (ANL) Advanced Photon Source (APS). The code BI, created by Ivan Bazarov, is benchmarked against our own code for simpler Accelerators. Then the full ERL is simulated and the results analyzed. We conclude that the ERL, if built, would theoretically be stable. Therefore, it would be feasible to build it.

Abstract:  We show that there is a mildly nonlinear threedimensional system of ordinary differential equations—realizable by a rather simple electronic circuit—capable of producing a generalized attracting horseshoe map. A system specifically designed to have a Poincaré section yielding the desired map is described, but not pursued due to its complexity, which makes the construction of a circuit realization exceedingly difficult. Instead, the generalized attracting horseshoe and its trapping region is obtained by using a carefully chosen Poincaré map of the Rössler attractor. Novel numerical techniques are employed to iterate the map of the trapping region to approximate the chaotic strange attractor contained in the generalized attracting horseshoe, and an electronic circuit is constructed to produce the map. Several potential applications of the idea of a generalized attracting horseshoe and a physical electronic circuit realization are proposed.

Abstract:  Over the past decade the study of fluidic droplets bouncing and skipping (or "walking") on a vibrating fluid bath has gone from an interesting experiment to a vibrant research field. The field exhibits challenging fluids problems, potential connections with quantum mechanics, and complex nonlinear dynamics. We detail advancements in the field of walking droplets through the lens of Dynamical Systems Theory, and outline questions that can be answered using dynamical systems analysis. The article begins by discussing the history of the fluidic experiments and their resemblance to quantum experiments. With this physics backdrop, we paint a portrait of the complex nonlinear dynamics present in physical models of various walking droplet systems. Naturally, these investigations lead to even more questions, and some unsolved problems that are bound to benefit from rigorous Dynamical Systems Analysis are outlined.

Abstract:  In recent decades computeraided technologies have become prevalent in medicine, however, cancer drugs are often only tested on in vitro cell lines from biopsies. We derive a full threedimensional model of inhomogeneousanisotropic diffusion in a tumor region coupled to a binary population model, which simulates in vivo scenarios faster than traditional cellline tests. The diffusion tensors are acquired using diffusion tensor magnetic resonance imaging from a patient diagnosed with glioblastoma multiform. Then we numerically simulate the full model with finite element methods and produce drug concentration heat maps, apoptosis hotpots, and doseresponse curves. Finally, predictions are made about optimal injection locations and volumes, which are presented in a form that can be employed by doctors and oncologists.

Abstract:  We identify two types of (compound) dynamical bifurcations generated primarily by interactions of an invariant attracting submanifold with stable and unstable manifolds of hyperbolic fixed points. These bifurcation types  inspired by recent investigations of mathematical models for walking droplet (pilotwave) phenomena  are introduced and illustrated. Some of the oneparameter bifurcation types are analyzed in detail and extended from the plane to higherdimensional spaces. A few applications to walking droplet dynamics are analyzed.

Abstract:  Clinical studies often track doseresponse curves of subjects over time. One can easily model the doseresponse curve at each time point with Hill equation, but such a model fails to capture the temporal evolution of the curves. On the other hand, one can use Gompertz equation to model the temporal behaviors at each dose without capturing the evolution of time curves across dosage.

Abstract:  It has been shown recently that changing the fluidic properties of a drug can improve its efficacy in ablating solid tumors. We develop a modeling framework for tumor ablation and present the simplest possible model for drug diffusion in a porous spherical tumor with leaky boundaries and assuming cell death eventually leads to ablation of that cell effectively making the two quantities numerically equivalent. The death of a cell after a given exposure time depends on both the concentration of the drug and the amount of oxygen available to the cell, which we assume is the same throughout the tumor for further simplicity. It can be assumed that a minimum concentration is required for a cell to die, effectively connecting diffusion with efficacy. The concentration threshold decreases as exposure time increases, which allows us to compute doseresponse curves. Furthermore, these curves can be plotted at much finer time intervals compared to that of experiments, which may possibly be used to produce a dosethresholdresponse surface giving an observer a complete picture of the drug's efficacy for an individual. In addition, since the diffusion, leak coefficients, and the availability of oxygen is different for different individuals and tumors, we produce artificial replication data through bootstrapping to simulate error. While the usual datadriven model with sigmoidal curves use 12 free parameters, our mechanistic model only has two free parameters, allowing it to be open to scrutiny rather than forcing agreement with data. Even so, the simplest model in our framework, derived here, shows close agreement with the bootstrapped curves and reproduces wellestablished relations, such as Haber's rule.

Abstract:  Recent experiments on walking droplets in an annular cavity showed the existence of complex dynamics including chaotically changing velocity. This article presents models, influenced by the kicked rotator/standard map, for both single and multiple droplets. The models are shown to achieve both qualitative and quantitative agreement with the experiments, and make predictions about heretofore unobserved behavior. Using dynamical systems techniques and bifurcation theory, the single droplet model is analyzed to prove dynamics suggested by the numerical simulations.

Abstract:  A generalized attracting horseshoe is introduced as a new paradigm for describing chaotic strange attractors (of arbitrary finite rank) for smooth and piecewise smooth maps f from Q to Q, where Q is a homeomorph of the unit interval in real mspace for any integer m > 1. The main theorems for generalized attracting horseshoes are shown to apply to Henon and Lozi maps, thereby leading to rather simple new chaotic strange attractor existence proofs that apply to a range of parameter values that includes those of earlier proofs.

Abstract:  It has been observed through experiments and SPICE simulations that logical circuits based upon Chua’s circuit exhibit complex dynamical behaviour. This behaviour can be used to design analogues of more complex logic families and some properties can be exploited for electronics applications. Some of these circuits have been modelled as systems of ordinary differential equations. However, as the number of components in newer circuits increases so does the complexity. This renders continuous dynamical systems models impractical and necessitates new modelling techniques. In recent years, some discrete dynamical models have been developed using various simplifying assumptions. To create a robust modelling framework for chaotic logical circuits, we developed both deterministic and stochastic discrete dynamical models, which exploit the natural recurrence behaviour, for two chaotic NOR gates and a chaotic set/reset flipflop. This work presents a complete applied mathematical investigation of logical circuits. Experiments on our own designs of the above circuits are modelled and the models are rigorously analysed and simulated showing surprisingly close qualitative agreement with the experiments. Furthermore, the models are designed to accommodate dynamics of similarly designed circuits. This will allow researchers to develop ever more complex chaotic logical circuits with a simple modelling framework.

Abstract:  Some interesting variants of walking droplet based discrete dynamical bifurcations arising from diffeomorphisms are analyzed in detail. A notable feature of these new bifurcations is that, like Smale horseshoes, they can be represented by simple geometric paradigms, which markedly simplify their analysis. The twodimensional diffeomorphisms that produce these bifurcations are called sigma maps or double sigma maps for reasons that are made manifest in this investigation. Several examples are presented along with their dynamical simulations.

Abstract:  Bouncing droplets on a vibrating fluid bath can exhibit waveparticle behavior, such as being propelled by interacting with its own wave field. These droplets seem to walk across the bath, and thus are dubbed walkers. Experiments have shown that walkers can exhibit exotic dynamical behavior indicative of chaos. While the integrodifferential models developed for these systems agree well with the experiments, they are difficult to analyze mathematically. In recent years, simpler discrete dynamical models have been derived and studied numerically. The numerical simulations of these models show evidence of exotic dynamics such as period doubling bifurcations, Neimark–Sacker (N–S) bifurcations, and even chaos. For example, in [1], based on simulations Gilet conjectured the existence of a supercritical NS bifurcation as the damping factor in his one dimensional path model. We prove Gilet’s conjecture and more; in fact, both supercritical and subcritical (NS) bifurcations are produced by separately varying the damping factor and waveparticle coupling for all eigenmode shapes. Then we compare our theoretical results with some previous and new numerical simulations, and find complete qualitative agreement. Furthermore, evidence of chaos is shown by numerically studying a global bifurcation.

Abstract:  We describe a simple mechanical system, a ball rolling along a speciallydesigned landscape, which mimics the wellknown twobounce resonance in solitary wave collisions, a phenomenon that has been seen in countless numerical simulations but never in the laboratory. We provide a brief history of the solitary wave problem, stressing the fundamental role collectivecoordinate models played in understanding this phenomenon. We derive the equations governing the motion of a point particle confined to such a surface and then design a surface on which to roll the ball, such that its motion will evolve under the same equations that approximately govern solitary wave collisions. We report on physical experiments, carried out in an undergraduate applied mathematics course, that seem to exhibit the twobounce resonance.

Abstract:  A simple discrete planar dynamical model for the ideal (logical) R–S flipflop circuit is developed with an eye toward mimicking the dynamical behavior observed for actual physical realizations of this circuit. It is shown that the model exhibits most of the qualitative features ascribed to the R–S flipflop circuit, such as an intrinsic instability associated with unit set and reset inputs, manifested in a chaotic sequence of output states that tend to oscillate among all possible output states, and the existence of periodic orbits of arbitrarily high period that depend on the various intrinsic system parameters. The investigation involves a combination of analytical methods from the modern theory of discrete dynamical systems, and numerical simulations that illustrate the dazzling array of dynamics that can be generated by the model. Validation of the discrete model is accomplished by comparison with certain Poincaré map like representations of the dynamics corresponding to threedimensional differential equation models of electrical circuits that produce R–S flipflop behavior.

Abstract:  Logical circuits and waveparticle duality have been studied for most of the 20th century. During the current century scientists have been thinking differently about these wellstudied systems. Specifically, there has been great interest in chaotic logical circuits and hydrodynamic quantum analogs. Traditional logical circuits are designed with minimal uncertainty. While this is straightforward to achieve with electronic logic, other logic families such as fluidic, chemical, and biological, naturally exhibit uncertainties due to their inherent nonlinearity. In recent years, engineers have been designing electronic logical systems via chaotic circuits. While traditional boolean circuits have easily determined outputs, which renders dynamical models unnecessary, chaotic logical circuits employ components that behave erratically for certain inputs. There has been an equally dramatic paradigm shift for studying waveparticle systems. In recent years, experiments with bouncing droplets (called walkers) on a vibrating fluid bath have shown that quantum analogs can be studied at the macro scale. These analogs help us ask questions about quantum mechanics that otherwise would have been inaccessible. They may eventually reveal some unforeseen properties of quantum mechanics that would close the gap between philosophical interpretations and scientific results. Both chaotic logical circuits and walking droplets have been modeled as differential equations. While many of these models are very good in reproducing the behavior observed in experiments, the equations are often too complex to analyze in detail and sometimes even too complex for tractable numerical solution. These problems can be simplified if the models are reduced to discrete dynamical systems. Fortunately, both systems are very naturally timediscrete. For the circuits, the states change very rapidly and therefore the information during the process of change is not of importance. And for the walkers, the position when a wave is produced is important, but the dynamics of the droplets in the air are not. This dissertation is an amalgam of results on chaotic logical circuits and walking droplets in the form of experimental investigations, mathematical modeling, and dynamical systems analysis. Furthermore, this thesis makes connections between the two topics and the various scientific disciplines involved in their studies.

Abstract:  Peixoto’s structural stability and density theorems represent milestones in the modern theory of dynamical systems and their applications. Despite the importance of these theorems, they are often treated rather superficially, if at all, in upper level undergraduate courses on dynamical systems or differential equations. This is mainly because of the depth and length of the proofs.
