DNA based networks, nanostructures, and meta-stable states
… approach presented here aims to create meta-stable DNA nanostructures based on a DNA hairpin loop that can mimic the enzyme-substrate binding mechanism. This mechanism is demonstrated using a "strand displacement strategy" (SDS). Lastly, we employed a novel way of organizing hairpin loop DNA …

Stochastically Stable States for Perturbed Repeated Play of Coordination Games
… irreducible Markov process on a set of history states describing the most recent m stages of play. At every stage, each player draws a sample from the history state to forecast his opponent's behavior and either moves to maximize his single-stage expected payoff or commits an error. As the error …

On the complexity of energy landscapes: algorithms and a direct test of the Edwards conjecture
When the states of a system can be described by the extrema of a high-dimensional function, the characterisation of its complexity, i.e. the enumeration of the accessible stable states, can be reduced to a sampling problem. In this thesis a robust numerical protocol is established, capable of …

Design and implementation of an analyzer for a timed pi-calculus
… performs analyses such as detection of deadlock states, stable states etc. To improve performance, the analyzer uses some transformation techniques to simplify the input kiltera model without changing its behavior. We provide a detailed description of the design and implementation of the analyzer …

Use of a triboelectric generator for a tunable wideband energy harvester and a threshold shock sensor
… A clamped-clamped buckled beam will switch stable states when a threshold shock amplitude is experienced and a voltage peak will occur during this switching of states. Levels of input acceleration can be related to voltage output, which increases the value of the concept. Thorough continuous …

A Change in Fish Assemblages in the Pascagoula River, MS
… river system in the contiguous United States and have seen a change in fish assemblages over time. Examination of long-term fish assemblage data show that the mainstem Pascagoula River and its two major tributaries (mainstem Leaf and Chickasawhay Rivers) have been dominated by five …

Analysis and Simulation of Kinetic Model for Active Suspensions
… shear, we give some bifurcation diagrams of the stable states in some parametric spaces through numerical simulations. Some rheological properties are also examined. Finally, we study the spatio-temperal structures of suspensions by taking into account the long-range particle interactions with …

The mechanisms behind alternative community states: Understanding producer composition in temporary and semipermanent wetlands
… in that a discrete set of community states (or distinct taxa assemblages) have been observed repeatedly in one ecosystem type. Many hypotheses have been proposed to explain this discontinuous variation in community composition over space and time. I examined the applicability of these …

General incentives in finite game theory
… that preserve the strategy space. Incentive stable states, ISS, for general incentive dynamics will be defined as an analog to the concept of the evolutionary stable states, ESS, in the replicator dynamics. The connection between the replicator dynamics and information theory is discussed. Of …

Design of a robust ratiometric sensor and a long-term memory genetic toggle switch
… memory device, which can be toggled between two stable states that can be maintained for long time despite stochastic fluctuations. These two circuit designs can be widely applied in many diagnostic applications, such as through engineered bacteria in the gut, and at the same time they offer …

Breaking Away: The Role of Homeostatic Drive in Perpetuating Depression
… These networks were analyzed to find any stable regulatory regimes possible given the established connections. Analysis indicated that this model network supported two distinct and stable homeostatic regimes. The first corresponds to typical health, while the second presents with …

Characterization of the Roles of Intrinsically Disordered Regions from RNA-Binding Proteins in Phase Separation
… Over time, these droplets mature into more stable states, as assessed by slowed fluorescence recovery after photobleaching and resistance to salt. Maturation often coincides with the formation of fibrous structures. Pathological mutation within IDRs leads to the acceleration of maturation. …

Design of Kresling inspired architected materials by using Polyjet technique
… such as tunable energy absorption and multi-stable states. Initially, a quantitative review of the achieved mechanical performance of PJ architected materials in the context of Ashby charts was developed. Subsequently, the manufacturing limitations of PJ were assessed to then determine …

Segmented binary control of shape memory actuator systems

Instead of driving a current to the entire SMA wire and controlling the wire length based on the analogue strain-temperature characteristics, the new method controls the binary …

MIW Sequences
… Building on this work, convergence of MIW ground states to the normal ground state of the quantum harmonic oscillator has been shown via Stein's method [13, 5,15, 12]. In the Wasserstein-1 metric, this occurs with rate $\calO(\sqrt{\log N}/N)$. In this context, we define a general notion of MIW …

Functional nucleic acids as substrate for information processing

Impact of Stochastic Transcriptional Delay on Gene Networks
… motifs. Next we examine how such delay affects bistable systems. We investigate several stochastic models of bistable gene networks and find that increasing delay dramatically increases the mean residence times near stable states. We show that this behavior can be explained using a non-Markovian, …

Ultracold Molecules: The Effect of Electromagnetic Fields

The elastic behavior of polymer chains: theory and simulations
