description: My Ph. D. work is on altering material properties to improve or apply in device applications and probing the manipulated properties through linear/ nonlinear optical methods. I focused my study on three types of structural modifications. First, in Chapter 2, I applied strain on a 3D integrated silicon circuit structure and BaTiO₃ thin film. Silicon, well-understood bulk material and most popular semiconductor platform, acquires new electronic and optical properties under strain. In addition, one can significantly control the ferroelectric and electro-optic properties of BaTiO₃ thin film, a traditional perovskite ferroelectric, by applying strain via a piezoelectric substrate, as shown in Chapter 5. Second, I engineered well-characterized bulk materials into thin films, as thin as 1 nm. In Chapter 4, I measured retention time of ferroelectric polarization on BaTiO₃ film thicknesses in the range of 10-20 nm. In addition, the thickness of the layers of a 2D material, e.g. In₂Se₃, introduces variations in bandgaps, dielectric functions, and/or absorption, which will be shown in Chapter 6. Lastly, I characterized the displacive and disorder-to-order transitions in ferroelectric materials. For example, in Chapter 3, we discovered order-disorder ferroelectric mechanism in double perovskites synthesized by Spark-plasma-sintering method and studied their Curie temperatures. Through these projects, I discovered new ways of controlling material properties and studied their underlying origins of the emerging phenomena using optical methods

description: A quantum physical projector is proposed for generally covariant theories which are derivable from a Lagrangian. The projector is the quantum analogue of the integral over the generators of finite one-parameter subgroups of the gauge symmetry transformations which are connected to the identity. Gauge variables are retained in this formalism, thus permitting the construction of spacetime area and volume operators in a tentative spacetime loop formulation of quantum general relativity.

description: This dissertation presents results of optical characterization of asphalt binder microstructure. We use noncontact optical microscopy methods to observe microstructure at the surface as well as in the bulk of asphalt binder samples. Normal incidence optical microscopy is used to image elongated, striped, surface microstructures (known as ’bees’ since they resemble bumble-bees) with comparable resolution to atomic force microscopy (AFM). Narrow band dark field optical microscopy is used to measure surface microstructure areal density and bulk microstructure volume density. Short wavelength illumination images surface microstructures, while longer wavelength near infrared (NIR) illumination penetrates into the bulk and images sub-surface microstructures. We subject the binder to temperature cycles and observe the resulting microstructure kinetics. We benchmark these optical measurements with rheometry measurements obtained from identical thermal cycles. We also use optical methods to observe surface ’bee’ microstructure variations due to interfacial tension modifications and compare these results to thin film mechanics theory

description: We present the results of a large search for intrinsic HI 21 cm and OH 18 cm absorption in 145 compact radio sources in the redshift range 0.02< z <3.8 with the Green Bank Telescope. We re-detect HI 21 cm absorption toward six known absorption systems but detect no new HI or OH absorption in 102 interference-free sources. 79 sources have not previously been observed for HI 21 cm absorption. We recover a mean optical depth limit of $τ_{3σ}<0.023$ for all the non-detections in the survey. Our results do not support the high intrinsic absorption rates found by previous studies in compact radio sources at low redshift. Our results do, however, support the hypothesis proposed by Curran et al. (2008) that high ultraviolet (UV) luminosity active galactic nuclei (AGN) do not show intrinsic HI 21 cm absorption, confirming a threshold of $L_{\rm UV} = 10^{23}$ W Hz$^{-1}$, above which our intrinsic absorption fraction is zero (54 sources). The exact nature of the UV luminosity effect on HI absorption systems remains ambiguous. We additionally find no statistical correlation between the 1.4 GHz radio luminosity or the source size and the 21~cm absorption detection rate. We attribute the lack of intrinsic absorption in our survey to the UV luminosity effect caused by an optical selection bias and a decreased column density sensitivity with increasing redshift due to lower radio continuum flux densities, high radio frequency interference, and higher telescope system temperatures at low frequencies.

description: The notions of two-dimensional area, Killing fields and matter flux are introduced in the setting of causal fermion systems. It is shown that for critical points of the causal action, the area change of two-dimensional surfaces under a Killing flow in null directions is proportional to the matter flux through these surfaces. This relation generalizes an equation in classical general relativity due to Ted Jacobson to the setting of causal fermion systems.

description: Neural networks are increasingly used for intrusion detection on industrial control systems (ICS). With neural networks being vulnerable to adversarial examples, attackers who wish to cause damage to an ICS can attempt to hide their attacks from detection by using adversarial example techniques. In this work we address the domain specific challenges of constructing such attacks against autoregressive based intrusion detection systems (IDS) in an ICS setting. We model an attacker that can compromise a subset of sensors in a ICS which has a LSTM based IDS. The attacker manipulates the data sent to the IDS, and seeks to hide the presence of real cyber-physical attacks occurring in the ICS. We evaluate our adversarial attack methodology on the Secure Water Treatment system when examining solely continuous data, and on data containing a mixture of discrete and continuous variables. In the continuous data domain our attack successfully hides the cyber-physical attacks requiring 2.87 out of 12 monitored sensors to be compromised on average. With both discrete and continuous data our attack required, on average, 3.74 out of 26 monitored sensors to be compromised.

description: This paper deals with the boundary controllability of inviscid incompressible fluids for which thermal effects are important. They will be modeled through the so called Boussinesq approximation. In the zero heat diffusion case, by adapting and extending some ideas from J.-M.~Coron and O.~Glass, we establish the simultaneous global exact controllability of the velocity field and the temperature for 2D and 3D flows. When the heat diffusion coefficient is positive, we present some additional results concerning exact controllability for the velocity field and local null controllability of the temperature.

Schrödinger operator on homogeneous metric trees: spectrum in gaps

description: The paper studies the spectral properties of the Schrödinger operator $A_{gV} = A_0 + gV$ on a homogeneous rooted metric tree, with a decaying real-valued potential $V$ and a coupling constant $g\ge 0$. The spectrum of the free Laplacian $A_0 = -Δ$ has a band-gap structure with a single eigenvalue of infinite multiplicity in the middle of each finite gap. The perturbation $gV$ gives rise to extra eigenvalues in the gaps. These eigenvalues are monotone functions of $g$ if the potential $V$ has a fixed sign. Assuming that the latter condition is satisfied and that $V$ is symmetric, i.e. depends on the distance to the root of the tree, we carry out a detailed asymptotic analysis of the counting function of the discrete eigenvalues in the limit $g\to\infty$. Depending on the sign and decay of $V$, this asymptotics is either of the Weyl type or is completely determined by the behaviour of $V$ at infinity.

Comment on "Bounding and approximating parabolas for the spectrum of Heisenberg spin systems" by Schmidt, Schnack and Luban

description: Recently, Schmidt et al. proved that the energy spectrum of a Heisenberg spin system (HSS) is bounded by two parabolas, i.e. lines which depend on the total spin quantum number S as S(S+1). The prove holds for homonuclear HSSs which fulfill a weak homogenity condition. Moreover, the extremal values of the exact spectrum of various HSS which were studied numerically were found to lie on approximate parabolas, named rotational bands, which could be obtained by a shift of the boundary parabolas. In view of this, it has been claimed that the rotational band structure (RBS) of the energy spectrum is a general behavior of HSSs. Furthermore, since the approximate parabolas are very close to the true boundaries of the spectrum for the examples discussed, it has been claimed that the methods allow to predict the detailed shape of the spectrum and related properties for a general HSS. In this comment I will show by means of examples that the RBS hypothesis is not valid for general HSSs. In particular, weak homogenity is neither a necessary nor a sufficient condition for a HSS to exhibit a spectrum with RBS.

description: This paper concerns the null controllability of the two-phase 1D Stefan problem with distributed controls. This is a free-boundary problem that models solidification or melting processes. In each phase, a parabolic equation, completed with initial and boundary conditions must be satisfied; the phases are separated by a phase-change interface where an additional free-boundary condition is imposed. We assume that two localized sources of heating/cooling controls act on the system (one in each phase). We prove a local null controllability result: the temperatures and the interface can be respectively steered to zero and to a prescribed location provided the initial data and interface position are sufficiently close to the targets. The ingredients of the proofs are a compactness-uniqueness argument (to deduce appropriate observability estimates adapted to constraints) and a fixed-point formulation and resolution of the controllability problem (to deduce the result for the nonlinear system). We also prove a negative result corresponding to the case where only one control acts on the system and the interface does not collapse to the boundary.

C-section delivery alters the early life microbiome and neurodevelopment
Creators: name: Lessing, Jeremy Kyle
Publisher: name: No Publisher Supplied
Year: 2025

description: C-section (CS) delivery is associated with an increased risk of developing neurodevelopmental diseases, but mechanisms remain unknown. We hypothesize that birth mode affects neurodevelopment in a way that is reversible by microbial restoration. To test this hypothesis, we characterized brain development - hippocampus transcriptomics - and the gut microbiome in mice discordant to birth mode with and without microbial restoration after C-section birth. Restoration (CSR) was performed by exposure to the maternal vaginal microbiome at postnatal day 0 (P0). Experiments were performed on conventional B6129SF1/J and the 16p11.2del heterozygous mouse model of neurodevelopmental susceptibility. We collected gastrointestinal contents, dissected the hippocampus, and perfused whole brains at P7 and P21. We found significant effects of birth mode on the gut microbiome, although with small effect size, and partial restoration in the CSR group. At P7, there were alterations in 85 differentially abundant bacterial amplicon sequence variants (ASVs), of which 65% (55 taxa) were restored in the CSR group, mostly by ASVs shared between both vaginal and fecal communities. At P21, the CS-born mice showed altered the abundance of 203 ASVs, of which 53% (108 taxa) were restored in the CSR group. CS birth altered hippocampal gene expression, with an under expression of 69 genes and overexpression of 16 genes at P7, when compared with vaginally born and fostered animals. Gene ontology pathway analysis showed that CS increases cellular division/differentiation while decreasing synaptic plasticity. Microbial restoration after CS did not rescue gene expression. Overall, our findings show important early alterations in brain development caused by C-section. Although microbial restoration after C-section partially restored the microbiome, it was not enough to normalize brain gene expression at P7.
The growth of planetary embryos: orderly, runaway, or oligarchic?
Creators: name: Rafikov, Roman R.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We consider the growth of a protoplanetary embryo embedded in a planetesimal disk. We take into account the dynamical evolution of the disk caused by (1) planetesimal-planetesimal interactions, which increase random motions and smooth gradients in the disk, and (2) gravitational scattering of planetesimals by the embryo, which tends to heat up the disk locally and repels planetesimals away. The embryo's growth is self-consistently coupled to the planetesimal disk dynamics. We demonstrate that details of the evolution depend on only two dimensionless parameters incorporating all the physical characteristics of the problem: the ratio of the physical radius to the Hill radius of any solid body in the disk and the number of planetesimals inside the annulus of the disk with width equal to the planetesimal Hill radius. The results of exploration in the framework of our model of several situations typical for protosolar nebula can be summarized as follows: initially, the planetesimal disk dynamics is not affected by the presence of the embryo and the growth of the embryo's mass proceeds very rapidly in the runaway regime. Later on, when the embryo starts being dynamically important, its accretion slows down similar to the ``oligarchic'' growth picture. The scenario of orderly growth suggested by Safronov (1972) is never realized in our calculations; scenario of runaway growth suggested by Wetherill & Stewart (1989) is only realized for a limited range in mass. Slow character of the planetesimal accretion on the oligarchic stage of the embryo's accumulation leads to a considerable increase of the protoplanetary formation timescale compared to that following from a simple runaway accretion picture valid in the homogeneous planetesimal disks.

description: Multiplicative constants are a fundamental tool in the study of maximal representations. In this paper we show how to extend such notion, and the associated framework, to measurable cocycles theory. As an application of this approach, we define and study the Cartan invariant for measurable $\textup{PU}(m,1)$-cocycles of complex hyperbolic lattices.

A mixed formulation for the direct approximation of $L^2$-weighted controls for the linear heat equation

description: This paper deals with the numerical computation of null controls for the linear heat equation. The goal is to compute approximations of controls that drive the solution from a prescribed initial state to zero at a given positive time. In [Fernandez-Cara \& Münch, Strong convergence approximations of null controls for the 1D heat equation, 2013], a so-called primal method is described leading to a strongly convergent approximation of distributed control: the controls minimize quadratic weighted functionals involving both the control and the state and are obtained by solving the corresponding optimality conditions. In this work, we adapt the method to approximate the control of minimal square integrable-weighted norm. The optimality conditions of the problem are reformulated as a mixed formulation involving both the state and its adjoint. We prove the well-posedness of the mixed formulation (in particular the inf-sup condition) then discuss several numerical experiments. The approach covers both the boundary and the inner situation and is valid in any dimension.

description: The lattice dynamics in CuGeO$_3$ has been analyzed by the combination of inelastic neutron scattering studies and lattice dynamical model calculations. We report an almost complete set of dispersion curves along the three orthorhombic directions and along [101]. The dispersion of branches associated with the modes directly involved in the spin-Peierls transition allows to explain the particular propagation vector of the structural distortion in the dimerized phase.

description: Higgs bundles appeared a few decades ago as solutions to certain equations from physics and have attracted much attention in geometry as well as other areas of mathematics and physics. Here, we take a very informal stroll through some aspects of linear algebra that anticipate the deeper structure in the moduli space of Higgs bundles. (This note was produced for the MFO Snapshots of Modern Mathematics series, which is "designed to promote the understanding and appreciation of modern mathematics and mathematical research in the interested public world-wide.")

Stable Periodic Solutions to Lambda-Omega Lattice Dynamical Systems
Creators: name: Bramburger, Jason J.
Publisher: name: arXiv
Year: 2019
Subjects: subject: Dynamical Systems (math.DS)
subject: FOS: Mathematics

description: In this manuscript we consider the stability of periodic solutions to Lambda-Omega lattice dynamical systems. In particular, we show that an appropriate ansatz casts the lattice dynamical system as an infinite-dimensional fast-slow differential equation. In a neighbourhood of the periodic solution an invariant slow manifold is proven to exist, and that this slow manifold is uniformly exponentially attracting. The dynamics of solutions on the slow manifold become significantly more complicated and require a more delicate treatment. We present sufficient conditions to guarantee convergence on the slow manifold which is algebraic, as opposed to exponential, in the slow-time variable. Of particular interest to our work in this manuscript is the stability of a rotating wave solution, recently found to exist in the Lambda-Omega systems studied herein.
Gravitational waves from inspiralling compact binaries: Energy flux to third post-Newtonian order

description: The multipolar-post-Minkowskian approach to gravitational radiation is applied to the problem of the generation of waves by the compact binary inspiral. We investigate specifically the third post-Newtonian (3PN) approximation in the total energy flux. The new results are the computation of the mass quadrupole moment of the binary to the 3PN order, and the current quadrupole and mass octupole to the 2PN order. Wave tails and tails of tails in the far zone are included up to the 3.5PN order. The recently derived 3PN equations of binary motion are used to compute the time-derivatives of the moments. We find perfect agreement to the 3.5PN order with perturbation calculations of black holes in the test-mass limit for one body. Technical inputs in our computation include a model of point particles for describing the compact objects, and the Hadamard self-field regularization. Because of a physical incompleteness of the Hadamard regularization at the 3PN order, the energy flux depends on one unknown physical parameter, which is a combination of a parameter λin the equations of motion, and a new parameter θcoming from the quadrupole moment.

On reversible, endoreversible, and irreversible heat device cycles versus Carnot cycle: A pedagogical approach to account for losses

description: In this work we analyze the deviations of reversible cycles (for both heat engines and refrigerators) from the corresponding Carnot cycle operating between the same extreme temperatures and deviations of irreversible cycles from its corresponding reversible realization while putting emphasis on the corresponding losses. The endoreversible models fit in the proposed framework. Two suitable loss factors, which don't need the explicit calculation of entropy variations, are introduced. The behavior of these factors and their interplay allow for a clear and pedagogical visualization of where external and internal irreversibilities are located and their intensities in terms of the main variables describing the cycle. The analysis could be used as a starting point for more advanced studies on modeling and optimization of real devices and installations.

description: The Late Neolithic in Schleswig-Holstein is a period about which not much is known. A re-analysis of two old excavations near Archsum on the island of Sylt provides us with a case study on both domestic and funerary behaviour dating to the later part of the 3rd millennium BC. The LA 65 site consists of a long-house with a sunken floor, ploughmarks and pits which contain both Common Ware and Bell Beaker pottery, and a grave with a Scandinavian flint dagger. On the other hand, LA127 consists of a megalithic grave in which a secondary cremation burial was deposited, along with artefacts showing a complicated interaction of mythology, memory, heirlooms, and identity formation. In this paper we focus on a long-term perspective, and place the practices carried out here in a larger scale. The use of possible ancestral objects and places in the landscape is reviewed, and the place of specific “Bell Beaker”-affiliated objects (pottery, flint daggers, and stone wristguards) in the Late Neolithic of the southern Cimbrian Peninsula is discussed. The division between Bell Beaker associated objects and daggers is clearly visible in the funerary context all across Northern Germany and Denmark.

description: Robotic on-orbit servicing (OOS) is expected to be a key technology and concept for future sustainable space exploration. This paper develops a semi-analytical model for OOS systems analysis, responding to the growing needs and ongoing trend of robotic OOS. An OOS infrastructure system is considered whose goal is to provide responsive services to the random failures of a set of customer modular satellites distributed in space (e.g., at the geosynchronous equatorial orbit). The considered OOS architecture is comprised of a servicer that travels and provides module-replacement services to the customer satellites, an on-orbit depot to store the spares, and a series of launch vehicles to replenish the depot. The OOS system performance is analyzed by evaluating the mean waiting time before service completion for a given failure and its relationship with the depot capacity. Leveraging the queueing theory and inventory management methods, the developed semi-analytical model is capable of analyzing the OOS system performance without relying on computationally costly simulations. The effectiveness of the proposed model is demonstrated using a case study compared with simulation results. This paper is expected to provide a critical step to push the research frontier of analytical/semi-analytical models development for complex space systems design.
