Year: 1996
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Among the expected sources of gravitational waves for the Laser Interferometer Space Antenna (LISA) is the capture of solar-mass compact stars by massive black holes residing in galactic centers. We construct a simple model for such a capture, in which the compact star moves freely on a circular orbit in the equatorial plane of the massive black hole. We consider the gravitational waves emitted during the late stages of orbital evolution, shortly before the orbiting mass reaches the innermost stable circular orbit. We construct a simple model for the gravitational-wave signal, in which the phasing of the waves plays the dominant role. The signal's behavior depends on a number of parameters, including $μ$, the mass of the orbiting star, $M$, the mass of the central black hole, and $J$, the black hole's angular momentum. We calculate, using our simplified model, and in the limit of large signal-to-noise ratio, the accuracy with which these quantities can be estimated during a gravitational-wave measurement. Our simplified model also suggests a method for experimentally testing the strong-field predictions of general relativity.

Optimal Trading Strategies Under Arbitrage
Creators: Ruf, Johannes Karl Dominik
Publisher: name: Columbia University
Year: 2011
Subjects: subject: Mathematics
subject: FOS: Mathematics
subject: Finance

description: This thesis analyzes models of financial markets that incorporate the possibility of arbitrage opportunities. The first part demonstrates how explicit formulas for optimal trading strategies in terms of minimal required initial capital can be derived in order to replicate a given terminal wealth in a continuous-time Markovian context. Towards this end, only the existence of a square-integrable market price of risk (rather than the existence of an equivalent local martingale measure) is assumed. A new measure under which the dynamics of the stock price processes simplify is constructed. It is shown that delta hedging does not depend on the "no free lunch with vanishing risk" assumption. However, in the presence of arbitrage opportunities, finding an optimal strategy is directly linked to the non-uniqueness of the partial differential equation corresponding to the Black-Scholes equation. In order to apply these analytic tools, sufficient conditions are derived for the necessary differentiability of expectations indexed over the initial market configuration. The phenomenon of "bubbles," which has been a popular topic in the recent academic literature, appears as a special case of the setting in the first part of this thesis. Several examples at the end of the first part illustrate the techniques contained therein. In the second part, a more general point of view is taken. The stock price processes, which again allow for the possibility of arbitrage, are no longer assumed to be Markovian, but rather only It^o processes. We then prove the Second Fundamental Theorem of Asset Pricing for these markets: A market is complete, meaning that any bounded contingent claim is replicable, if and only if the stochastic discount factor is unique. Conditions under which a contingent claim can be perfectly replicated in an incomplete market are established. Then, precise conditions under which relative arbitrage and strong relative arbitrage with respect to a given trading strategy exist are explicated. In addition, it is shown that if the market is quasi-complete, meaning that any bounded contingent claim measurable with respect to the stock price filtration is replicable, relative arbitrage implies strong relative arbitrage. It is further demonstrated that markets are quasi-complete, subject to the condition that the drift and diffusion coefficients are measurable with respect to the stock price filtration.
Dissipative Computing: A General Thermodynamic Framework for Information Processing in Open Systems
Creators: name: Todd, Ian
Publisher: name: Zenodo
Year: 2025

description: I introduce a general theory of dissipative computing—a paradigm that recognizes com- putation as an inherently thermodynamic process emerging from dimensional coherence and entropy export in open systems. Building on recent work connecting information storage- transmission trade-offs to the emergence of power-law distributions, I establish that com- putation in physical systems fundamentally depends on leveraging both threshold-crossing events and sub-threshold dynamics within a structured entropy export framework. While conventional computing treats dissipation as a limitation to minimize, this approach reveals how controlled dissipation enables computational capabilities through the formation and degradation of coherent states. I formalize basic computational operations as coherence transformations with predictable entropy costs, develop quantitative relationships between computational power and dissipative dynamics, and establish design principles for hierarchical architectures that exploit these properties. Specifically, I demonstrate that state- of-the-art AI architectures like transformers inherently exploit these dissipative principles, revealing their fundamental connection to biological cognition and physical systems. This framework unifies observations across biological, neural, social, and physical systems, revealing them as manifestations of the same underlying computational process. By grounding computation in thermodynamic first principles and explicitly addressing the computational role of sub-threshold interactions, I provide a foundation for understanding both natural and engineered computational systems as dissipative processes that leverage energy gradients to create, transform, and transmit information.

Optimal Transport and Equilibrium Problems in Mathematical Finance

Subjects: subject: Mathematics
subject: FOS: Mathematics

subject: Equilibrium

description: The thesis consists of three independent topics, each of which is discussed in an individual chapter.
      The first chapter considers a multiperiod optimal transport problem where distributions μ0, . . . , μn are prescribed and a transport corresponds to a scalar martingale X with marginals Xt ∼ μt. We introduce particular couplings called left-monotone transports; they are characterized equivalently by a no-crossing property of their support, as simultaneous optimizers for a class of bivariate transport cost functions with a Spence–Mirrlees property, and by an order-theoretic minimality property. Left-monotone transports are unique if μ0 is atomless, but not in general. In the one-period case n = 1, these transports reduce to the Left-Curtain coupling of Beiglbo ̈ck and Juillet. In the multiperiod case, the bivariate marginals for dates (0,t) are of Left-Curtain type, if and only if μ0, . . . , μn have a specific order property. The general analysis of the transport problem also gives rise to a strong duality result and a description of its polar sets. Finally, we study a variant where the intermediate marginals μ1,...,μn−1 are not prescribed.
      The second chapter studies the convergence of Nash equilibria in a game of optimal stopping. If the associated mean field game has a unique equilibrium, any sequence of n-player equilibria converges to it as n → ∞. However, both the finite and infinite player versions of the game often admit multiple equilibria. We show that mean field equilibria satisfying a transversality condition are limit points of n-player equilibria, but we also exhibit a remarkable class of mean field equilibria that are not limits, thus questioning their interpretation as “large n” equilibria.
      The third chapter studies the equilibrium price of an asset that is traded in continuous time between N agents who have heterogeneous beliefs about the state process underlying the asset’s payoff. We propose a tractable model where agents maximize expected returns under quadratic costs on inventories and trading rates. The unique equilibrium price is characterized by a weakly coupled system of linear parabolic equations which shows that holding and liquidity costs play dual roles. We derive the leading-order asymptotics for small transaction and holding costs which give further insight into the equilibrium and the consequences of illiquidity.

description: Human Activity Recognition (HAR) using deep neural network has become a hot topic in human-computer interaction. Machine can effectively identify human naturalistic activities by learning from a large collection of sensor data. Activity recognition is not only an interesting research problem, but also has many real-world practical applications. Based on the success of residual networks in achieving a high level of aesthetic representation of the automatic learning, we propose a novel \textbf{A}symmetric \textbf{R}esidual \textbf{N}etwork, named ARN. ARN is implemented using two identical path frameworks consisting of (1) a short time window, which is used to capture spatial features, and (2) a long time window, which is used to capture fine temporal features. The long time window path can be made very lightweight by reducing its channel capacity, yet still being able to learn useful temporal representations for activity recognition. In this paper, we mainly focus on proposing a new model to improve the accuracy of HAR. In order to demonstrate the effectiveness of ARN model, we carried out extensive experiments on benchmark datasets (i.e., OPPORTUNITY, UniMiB-SHAR) and compared with some conventional and state-of-the-art learning-based methods. Then, we discuss the influence of networks parameters on performance to provide insights about its optimization. Results from our experiments show that ARN is effective in recognizing human activities via wearable datasets.

description: Reinforcement learning (RL) has attracted rapidly increasing interest in the machine learning and artificial intelligence communities in the past decade. With tremendous success already demonstrated for Game AI, RL offers great potential for applications in more complex, real world domains, for example in robotics, autonomous driving and even drug discovery. Although researchers have devoted a lot of engineering effort to deploy RL methods at scale, many state-of-the art RL techniques still seem mysterious - with limited theoretical guarantees on their behaviour in practice. In this thesis, we focus on understanding convergence guarantees for two key ideas in reinforcement learning, namely Temporal difference learning and policy gradient methods, from an optimization perspective. In Chapter 2, we provide a simple and explicit finite time analysis of Temporal difference (TD) learning with linear function approximation. Except for a few key insights, our analysis mirrors standard techniques for analyzing stochastic gradient descent algorithms, and therefore inherits the simplicity and elegance of that literature. Our convergence results extend seamlessly to the study of TD learning with eligibility traces, known as TD(λ), and to Q-learning for a class of high-dimensional optimal stopping problems. In Chapter 3, we turn our attention to policy gradient methods and present a simple and general understanding of their global convergence properties. The main challenge here is that even for simple control problems, policy gradient algorithms face non-convex optimization problems and are widely understood to converge only to a stationary point of the objective. We identify structural properties -- shared by finite MDPs and several classic control problems -- which guarantee that despite non-convexity, any stationary point of the policy gradient objective is globally optimal. In the final chapter, we extend our analysis for finite MDPs to show linear convergence guarantees for many popular variants of policy gradient methods like projected policy gradient, Frank-Wolfe, mirror descent and natural policy gradients.

description: There has been increasing development in personalized interventions that are tailored to uniquely evolving health status of each patient over time. In this dissertation, we investigate two problems: (1) the construction of individualized mobile health (mHealth) application recommender system; and (2) the estimation of optimal dynamic treatment regimes (DTRs) from a multi-stage clinical trial study. The dissertation is organized as follows. In Chapter 1, we provide a brief background on personalized medicine and two motivating examples which illustrate the needs and benefits of individualized treatment policies. We then introduce reinforcement learning and various methods to obtain the optimal DTRs as well as Q-learning procedure which is a popular method in the DTR literature. In Chapter 2, we propose a partial regularization via orthogonality using the adaptive Lasso (PRO-aLasso) to estimate the optimal policy which maximizes the expected utility in the mHealth setting. We also derive the convergence rate of the expected outcome of the estimated policy to that of the true optimal policy. The PRO-aLasso estimators are shown to enjoy the same oracle properties as the adaptive Lasso. Simulations and real data application demonstrate that the PRO-aLasso yields simple, more stable policies with better results as compared to the adaptive Lasso and other competing methods. In Chapter 3, we propose a penalized A-learning with a Lasso-type penalty for the construction of optimal DTR and derive generalization error bounds of the estimated DTR. We first examine the relationship between value and the Q-functions, and then we provide a finite sample upper bound on the difference in values between the optimal DTR and the estimated DTR. In practice, we implement a multi-stage PRO-aLasso algorithm to obtain the optimal DTR. Simulation results show advantages of the proposed methods over some existing alternatives. The proposed approach is also demonstrated with the data from a depression clinical trial study. In Chapter 4, we present future work and concluding remarks.
Path-wise control of stochastic systems: overcoming the curse of causality
Creators: name: Mellone, Alberto
Publisher: name: Imperial College London
Year: 2021

description: In this thesis we address the topic of path-wise control of stochastic systems defined by stochastic differential equations. By path-wise control we mean that the controller's decisions are not intended to regulate the moments of the state or the output (or a function of them), as customary in stochastic control. Instead, we aim at designing a controller that achieves a desired, specific, trajectory of the state (or the output) itself, for all possible realisations of the noise affecting the system. We show that path-wise control is cursed by insuperable causality issues, because in order to perfectly attain a predefined trajectory for each realisation of the noise, the controller needs to access measurements of the noise itself, which is not possible in practice. Therefore, we approach path-wise control in two steps. Firstly, we design idealistic controllers, which achieve exact regulation by employing a feedback of the noise. Although unrealistic, these designs are preliminary to the second step, i.e. the construction of practical controllers, which estimate the noise from measurements of available quantities (state or output) and use such estimates to perform approximate path-wise control in a hybrid way. We show that the performance of the practical controllers can retrieve the idealistic ones in a limit behaviour. In this framework we address two classical control problems. Firstly, we consider output regulation of linear stochastic systems. We show that the idealistic controllers achieve a zero steady-state tracking error, while the practical controllers allow for a nonzero steady-state error, which, however, can be made arbitrarily small by tuning a design parameter. Secondly, we consider the control of stochastic systems defined by nonlinear, control-affine, stochastic differential equations. In this case, we show that the idealistic controllers achieve exact feedback linearisation and output tracking, while the practical controllers achieve state (and output) trajectories which can be made close to the idealistic ones by tuning a design parameter, thus obtaining approximate feedback linearisation and tracking.

description: We investigate autonomous stochastic resonance in fully frustrated Josephson-junction ladders, which are driven by uniform constant currents. At zero temperature large currents induce oscillations between the two ground states, while for small currents the lattice potential forces the system to remain in one of the two states. At finite temperatures, on the other hand, oscillations between the two states develop even below the critical current; the signal-to-noise ratio is found to display array-enhanced stochastic resonance. It is suggested that such behavior may be observed experimentally through the measurement of the staggered voltage.

Garimpo Canaan : a successful case of reclamation of an artisanal gold mine in the Amazon

description: Deforestation in the Brazilian Amazon region was increased in the 1970’s. The total amount of forest already cut to the date is over 700,000 km² or over 18% of the original forest. Mining activities in the Amazon also escalated after 1970, with thousands of artisanal miners extracting gold and removing portions of forest and soil along the riverbanks and streams, causing deforestation and releasing sediments and mercury into the water bodies. In the last three decades, hundreds of thousands of pits were opened in the process of colluvial gold exploitation and most of these pits have never been refilled. Following a common trend, miners migrate to new areas without reclaiming the mines spreading the environmental impact all over the Amazon. About 300 to 600 new open pits formed by hydraulic monitor mining are opened annually in the Tapajós region, the world’s largest artisanal gold mining area. In the Tapajos River basin, an example of good artisanal gold mining practice was identified. The owner of the “Garimpo” Canaan has introduced outstanding environmental practices which have made the area a reference in reclamation of open pits in the region. In this site, most old pits have been backfilled with the tailings from new excavations. In some refilled pits the vegetation is recomposing naturally and others have been reforested. After 6 years of plantation some areas showed trees with average diameter of 15 cm, height of 10 m and volume of 23 m3/ha. This example represents not only an environmental achievement but also a long-term alternative of economic diversification for miners in the area, as the surface gold deposits have been depleting in a fast pace.

description: In order to better understand the structure of classical rings of invariants for binary forms, Dixmier proposed, as a conjectural homogeneous system of parameters, an explicit collection of invariants previously studied by Hilbert. We generalize Dixmier's collection and show that a particular subfamily is algebraically independent. Our proof relies on showing certain alternating sums of products of binomial coefficients are nonzero. Along the way we provide a very elementary proof à la Racah, namely, only using the Chu-Vandermonde Theorem, for Dixon's Summation Theorem. We also provide explicit computations of invariants, for the binary octavic, which can serve as ideal introductory examples to Gordan's 1868 method in classical invariant theory.

Finally, we investigate the sensitivity of our results to the infrared and observe that for large media the spectrum is weakly dependent on the infrared medium scale.

description: Geometrical cues play an essential role in neuronal growth. Here, we quantify axonal growth on surfaces with controlled geometries and report a general stochastic approach that quantitatively describes the motion of growth cones. We show that axons display a strong directional alignment on micro-patterned surfaces when the periodicity of the patterns matches the dimension of the growth cone. The growth cone dynamics on surfaces with uniform geometry is described by a linear Langevin equation with both deterministic and stochastic contributions. In contrast, axonal growth on surfaces with periodic patterns is characterized by a system of two generalized Langevin equations with both linear and quadratic velocity dependence and stochastic noise. We combine experimental data with theoretical analysis to measure the key parameters of the growth cone motion: angular distributions, correlation functions, diffusion coefficients, characteristics speeds and damping coefficients. We demonstrate that axonal dynamics displays a cross-over from an Ornstein-Uhlenbeck process to a non-linear stochastic regime when the geometrical periodicity of the pattern approaches the linear dimension of the growth cone. Growth alignment is determined by surface geometry, which is fully quantified by the deterministic part of the Langevin equation.

description: Single molecule biosensing techniques offer unique advantages and opportunities for basic biological studies and medical diagnostic applications. However, their signal levels are intrinsically very weak and can be easily masked by the noise from the sensor itself or the measurement electronics. Thus, the biosensing systems and devices must be carefully characterized and optimized to reduce noise. This thesis first presents optimizations that enable high bandwidth, single channel recordings of the calcium-induced calcium release channel ryanodine receptor 1. By directly integrating a suspended bilayer with a complementary metal oxide semiconductor transimpedance amplifier, the total input capacitance and, therefore, high frequency noise are lowered, enabling gating events to be recorded at an order of magnitude higher bandwidth than the previous state of the art. Next, low frequency noise optimizations for carbon nanotube transistors are explored using hexagonal boron nitride substrates. These devices have improved 1/f noise performance compared to equivalent devices on silicon oxide and demonstrate evidence of contact limited noise. Finally, a basic characterization of 1/f noise in carbon nanotubes is developed using correlated transport and noise measurements in crossed carbon nanotube homojunction devices. These methods of optimizing and characterizing noise can aid in the development of single molecule biosensors with improved temporal resolution and error rates.
Environmental management criteria for molybdenum and selenium : a review relevant to the mining industry.

description: Molybdenum (Mo) and selenium (Se) were previously identified as constituents of concern in neutral mine drainage. This concern led to a review of the toxicity and management criteria for these constituents in aquatic and terrestrial environments. The characteristics of Mo and Se, including typical sources, environmental fate and transport, key toxicity effects, and reported thresholds for animals of interest will be reviewed in this presentation. Integration of these effects and environmental fate identify that assessments of toxicity will be complete if a site-specific risk assessment framework is used. An example of a pathways analysis for the fate of Mo will be considered to illustrate a complete site assessment. This information reveals the management criteria for Mo and Se should reflect site-specific environmental characteristics and the use of generic guidelines can result in highly conservative discharge limits for aquatic receiving environments.

description: zeta-function methods are used to study the properties of the non-relativistic interacting Bose gas at finite temperature and density. Results for the ground state energy and pressure are obtained at both zero and finite temperature. The method used does not restrict the form of the interaction, which can be completely general. A similar procedure is then applied to evaluate the ground state energy of a binary mixture consisting of different bosons. Analytical results are obtained in the case where the two species have the same mass.

COMIC: Towards A Compact Image Captioning Model with Attention

description: Recent works in image captioning have shown very promising raw performance. However, we realize that most of these encoder-decoder style networks with attention do not scale naturally to large vocabulary size, making them difficult to be deployed on embedded system with limited hardware resources. This is because the size of word and output embedding matrices grow proportionally with the size of vocabulary, adversely affecting the compactness of these networks. To address this limitation, this paper introduces a brand new idea in the domain of image captioning. That is, we tackle the problem of compactness of image captioning models which is hitherto unexplored. We showed that, our proposed model, named COMIC for COMpact Image Captioning, achieves comparable results in five common evaluation metrics with state-of-the-art approaches on both MS-COCO and InstaPIC-1.1M datasets despite having an embedding vocabulary size that is 39x - 99x smaller.

Probing the local structure: macromolecular combs in external fields

description: Recent experimental methods allow to monitor the response of macromolecules to locally applied fields, complementing usual, mesoscopic techniques. Based on the Rouse-model and its extension to generalized Gaussian structures (GGS), we follow here the stretching of comb macromolecules under local fields. This leads to a wealth of informations about the structure: Namely, given the inhomogeneous architecture of combs, the dynamics and amount of stretching depend strongly on the position of the monomer on which the external fields act. We discuss both the theoretical and the experimental implications of our findings, given that micromanipulations can be supplemented by fluorescence measurements, which are very sensitive to changes in the intramolecular distances.

description: We use the monodromy method to compute expectation values of an arbitrary number of light operators in finitely excited ("heavy") eigenstates of holographic 2D CFT. For eigenstates with scaling dimensions above the BTZ threshold, these behave thermally up to small corrections, with an effective temperature determined by the heavy state. Below the threshold we find oscillatory and not decaying behavior. As an application of these results we compute the expectation of the out-of-time order arrangement of four light operators in a heavy eigenstate, i.e. a six-point function. Above the threshold we find maximally scrambling behavior with Lyapunov exponent $2πT_{\rm eff}$. Below threshold we find that the eigenstate OTOC shows persistent harmonic oscillations.

Stress-Energy Must be Singular on the Misner Space Horizon even for Automorphic Fields
Creators: name: Cramer, Claes R
name: Kay, Bernard S.
Publisher: name: arXiv
Year: 1996
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We use the image sum method to reproduce Sushkov's result that for a massless automorphic field on the initial globally hyperbolic region $IGH$ of Misner space, one can always find a special value of the automorphic parameter $α$ such that the renormalized expectation value $\langleα|T_{ab}|α\rangle$ in the {\it Sushkov state} ``$\langleα|\cdot|α\rangle$'' (i.e. the automorphic generalization of the Hiscock-Konkowski state) vanishes. However, we shall prove by elementary methods that the conclusions of a recent general theorem of Kay-Radzikowski-Wald apply in this case. I.e. for any value of $α$ and any neighbourhood $N$ of any point $b$ on the chronology horizon there exists at least one pair of non-null related points $(x,x') \in (N\cap IGH)\times (N\cap IGH)$ such that the renormalized two-point function of an automorphic field $G^α_{\rm ren}(x,x')$ in the Sushkov state is singular. In consequence $\langleα|T_{ab}|α\rangle$ (as well as other renormalized expectation values such as $\langleα|ϕ^2|α\rangle$) is necessarily singular {\it on} the chronology horizon. We point out that a similar situation (i.e. singularity {\it on} the chronology horizon) holds for states on Gott space and Grant space.
