Essays on the determinants of worker productivity and labor market outcomes

Worker productivity

description: This dissertation examines determinants of worker productivity, labor market outcomes, and population health. The ﬁrst chapter, previously published in the Journal of Public Economics, examines the impacts of cash assistance on refugee labor market outcomes. I exploit variation across states and over time in the generosity of cash assistance available to refugees upon arrival in the U.S. and study the impacts on wages and employment. I argue that cash assistance is randomly assigned to refugees conditional on characteristics such as education and country of origin, as refugee placement is decided by a committee that does not meet with the refugees or learn their preferences. I ﬁnd that refugees resettled with more generous cash assistance go on to earn higher wages, with no signiﬁcant change in the probability of employment. The eﬀects are largest for highly-educated refugees. The second chapter examines the impact of temperature on the productivity and job performance of outdoor workers in developing countries. I overcome data challenges with studying individual-level productivity by studying household survey interviewers as workers. Using data from Demographic and Health Survey interviewers in 46 countries, I ﬁnd that interviewers complete fewer interviews per hour worked on hot and humid days, driven by an increase in working hours. I also ﬁnd evidence that suggests that workers allocate their eﬀort towards tasks that are more easily observed by supervisors on hot days. The third chapter, previously published in Social Justice Research and co-authored with Diane Coﬀey and Dean Spears, examines the role of social inequality in population health outcomes in India, focusing on the case of casteism and child height in India. We describe evidence from the India Human Development Survey showing that children in villages with more strongly casteist attitudes are shorter on average, an association that is statistically explained by the association between casteism and the prevalence of open defecation.

description: The one-dimensional Klein-Gordon (KG) equation has been solved for the PT-symmetric generalized Woods-Saxon (WS) potential. The Nikiforov-Uvarov(NU} method which is based on solving the second-order linear differential equations by reduction to a generalized equation of hypergeometric type is used to obtain exact energy eigenvalues and corresponding eigenfunctions. We have also investigated the positive and negative exact bound states of the s-states for different types of complex generalized WS potentials.

description: We review the physics and phenomenology of wave dark matter: a bosonic dark matter candidate lighter than about 30 eV. Such particles have a de Broglie wavelength exceeding the average inter-particle separation in a galaxy like the Milky Way, and are well described as classical waves. We outline the particle physics motivations for them, including the QCD axion and ultra-light axion-like-particles such as fuzzy dark matter. The wave nature of the dark matter implies a rich phenomenology: (1) Wave interference leads to order unity density fluctuations on de Broglie scale. A manifestation is vortices where the density vanishes and around which the velocity circulates. There is one vortex ring per de Broglie volume on average. (2) For sufficiently low masses, soliton condensation occurs at centers of halos. The soliton oscillates and random walks, another manifestation of wave interference. The halo/subhalo abundance is suppressed at small masses, but the precise prediction from numerical wave simulations remains to be determined. (3) For ultra-light ~$10^{-22}$ eV dark matter, the wave interference substructures can be probed by tidal streams/gravitational lensing. The signal can be distinguished from that due to subhalos by the dependence on stream orbital radius/image separation. (4) Axion detection experiments are sensitive to interference substructures for moderately light masses. The stochastic nature of the waves affects the interpretation of experiments and motivates the measurement of correlation functions. Current constraints and open questions, covering detection experiments and cosmological/galactic/black-hole observations, are discussed.

description: We propose an adaptive approach in picking the wave-number parameter of absorbing boundary conditions for Schrödinger-type equations. Based on the Gabor transform which captures local frequency information in the vicinity of artificial boundaries, the parameter is determined by an energy-weighted method and yields a quasi-optimal absorbing boundary conditions. It is shown that this approach can minimize reflected waves even when the wave function is composed of waves with different group velocities. We also extend the split local absorbing boundary (SLAB) method [Z. Xu and H. Han, {\it Phys. Rev. E}, 74(2006), pp. 037704] to problems in multidimensional nonlinear cases by coupling the adaptive approach. Numerical examples of nonlinear Schrödinger equations in one- and two dimensions are presented to demonstrate the properties of the discussed absorbing boundary conditions.

description: The chief factor of the realization of the equivalent education for all children is the educator. The actual research had as a central target to investigate the knowledge, the views and the attitudes of the educators of the Primary Education in Thessalonica and in Larissa about the islamofobia and to realize if they are preoccupied by it and to what extent. There have been also investigated issues such as their familiarization degree, as far as the general principals of the Islamism was concerned, the Moslems’ life in Greece and their notions – attitudes – views which touch issues in relation to the woman’s position in Islamic community and its restrictions from religion, Islam in education, the relation between Islam and Christianism, the relation between terrorism – islamofobia – religion, as well as the corresponding attitude of the media. The comparison between the questioned educations of our two cities allowed us to realize some discrepancies between them, due to the different social – economic conditions which prevail in there.
The One-Way Speed of Light and the Milne Universe

description: In Einstein's Special Theory of Relativity, all observers measure the speed of light, $c$, to be the same. However, this refers to the round trip speed, where a clock at the origin times the outward and return trip of light reflecting off a distant mirror. Measuring the one-way speed of light is fraught with issues of clock synchronisation, and, as long as the average speed of light remains $c$, the speeds on the outward and return legs could be different. One objection to this anisotropic speed of light is that views of the distant universe would be different in different directions, especially with regards to the ages of observed objects and the smoothness of the Cosmic Microwave Background. In this paper, we explore this in the Milne universe, the limiting case of a Friedmann-Robertson-Walker universe containing no matter, radiation or dark energy. Given that this universe is empty, it can be mapped onto flat Minkowski space-time, and so can be explored in terms of the one-way speed of light. The conclusion is that the presence of an anisotropic speed of light leads to anisotropic time dilation effects, and hence observers in the Milne universe would be presented with an isotropic view of the distant cosmos.

Irreducible decomposition of Gaussian distributions and the spectrum of black-body radiation

description: It is shown that the energy of a mode of a classical chaotic field, following the continuous exponential distribution as a classical random variable, can be uniquely decomposed into a sum of its fractional part and of its integer part. The integer part is a discrete random variable (we call it Planck variable) whose distribution is just the Bose distribution yielding the Planck law of black-body radiation. The fractional part is the dark part (we call is dark variable) with a continuous distribution, which is, of course, not observed in the experiments. It is proved that the Bose distribution is infinitely divisible, and the irreducible decomposition of it is given. The Planck variable can be decomposed into an infinite sum of independent binary random variables representing the binary photons (more accurately photo-molecules or photo-multiplets) of energies 2^s*h*nu with s=0,1,2... . These binary photons follow the Fermi statistics. Consequently, the black-body radiation can be viewed as a mixture of statistically and thermodynamically independent fermion gases consisting of binary photons. The binary photons give a natural tool for the dyadic expansion of arbitrary (but not coherent) ordinary photon excitations. It is shown that the binary photons have wave-particle fluctuations of fermions. These fluctuations combine to give the wave-particle fluctuations of the original bosonic photons expressed by the Einstein fluctuation formula.

description: The Dark Energy Spectroscopic Instrument (DESI) is an ongoing spectroscopic survey to measure the dark energy equation of state to unprecedented precision. We describe the DESI Sky Continuum Monitor System, which tracks the night sky brightness as part of a system that dynamically adjusts the spectroscopic exposure time to produce more uniform data quality and to maximize observing efficiency. The DESI dynamic exposure time calculator (ETC) will combine sky brightness measurements from the Sky Monitor with data from the guider system to calculate the exposure time to achieve uniform signal-to-noise ratio (SNR) in the spectra under various observing conditions. The DESI design includes 20 sky fibers, and these are split between two identical Sky Monitor units to provide redundancy. Each Sky Monitor unit uses an SBIG STXL-6303e CCD camera and supports an eight-position filter wheel. Both units have been completed and delivered to the Mayall Telescope at the Kitt Peak National Observatory. Commissioning results show that the Sky Monitor delivers the required performance necessary for the ETC.

description: The exact meaning of the noise spectrum of eigenvalues of the covariance matrix is discussed. In order to better understand the possible phenomena behind the observed noise, the spectrum of eigenvalues of the covariance matrix is studied under a model where most of the true eigenvalues are zero and the parameters are non-stationary. The results are compared with real observation of Brazilian assets, suggesting that, although the non-stationarity seems to be an important aspect of the problem, partially explaining some of the eigenvalues as well as part of the kurtosis of the assets, it can not, by itself, provide all the corrections needed to make the proposed model fit the data perfectly.

description: A 457-m (1,500-ft) runway pavement extension is planned for the Georgetown-Scott County Airport (Marshall Field). The clay subgrade of the existing paved runway was stabilized with six percent (dry weight) hydrated lime. A request was made by the Kentucky Transportation Cabinet, Division of Aeronautics, to determine the feasibility of replacing a percentage of the hydrated lime stabilizer with fly ash for the extended runway subgrade. Kentucky Highway Investigative Task No. 27 was issued by the Transportation Cabinet to fund a laboratory study to determine the effects of partially replacing lime with Type F fly ash (FA). Using fly ash to replace lime could potentially, reduce stabilization cost and provide a means of using fly ash as a byproduct in lieu of landfill disposal. The subgrade extension was previously constructed to final grade with clay soils. A thin layer of topsoil and grass currently covers the subgrade. Stabilization of the extended runway is planned during pavement construction.

description: 音楽の自動生成の分野において、与えられた主旋律にコード進行などを付与す る和声付けは、主要な課題のひとつである。更に、和声付けの自動化は、作曲支援 だけでなく、音楽理論をモデル化するという重要な課題でもある。その中で、四 声体和声付けは様々な研究がされてきた。これらの研究の古くはエキスパートシ ステムなどのルールベースのアプローチがとられてきた。しかし、後述する音楽 的同時性と音楽的連続性を両立する網羅的なルールセットを設計するのは難しく、 近年では、隠れマルコフモデルやベイジアンネットワークなどの機械学習を用い ることが一般的である。 本研究では、確率推論に基づいた機械学習技術の一種であるベイジアンネット ワークを用いた四声体和声の自動生成について検討する。ベイジアンネットワーク を用いる際に最も重要な課題は、モデル (ベイジアンネットワークを構成するノー ドとアークの集合をさす) をどのように設計するかである。この設計を行う上で、 主に 2 点の留意点がある。ひとつは音楽的同時性と音楽的連続性を両立すること、 もうひとつは和音の適切な粒度で表現することである。 「音楽的同時性と音楽的連続性の両立」とは、楽譜における縦と横の関係の依 存関係をともに考慮することをさす。ここで、音楽的同時性とは同時になるいく つかの音において、声部間の協和な関係を保つこと、音楽的連続性とは声部内で 滑らか旋律を作りだすことをいう。この 2 つの片方が欠けると音楽的に不適切な 和声になる。 「和音の適切な粒度による表現」とは、学習データが有限であることを前提に、有限のデータで学習可能な程度の粒度で和音を表すことである。和音を表す上で、 最もよく用いられるのがコードネームである。コードネームは表現能力の高い表 記方法として広く知られているが、ヴォイシングやテンションノート、ベース音を 区別して記述すると数万種類になってしまい、有限のデータから出現確率を学習 することは困難である。これらの区別を行わなければコードネームの種類が大幅 に減らすことできるが、これらを区別せずに音楽的に適切な和声を生成すること は困難である。 本研究では、ベイジアンネットワークを次のように設計することで、これらの 問題を解決する。前者の問題に対しては、音楽的同時性と音楽的連続性をそれぞ れ適切なノード間のアークとして表現し、全体の確率が最大となる和声を推定す る。後者の問題に対しては、コードシンボルを含まないモデルを設計する。コー ドシンボルを考慮せずに、4 声部間のみの関係を考慮することで、コードシンボル の曖昧性の問題を解決し、適切な和音を推論することができる。 このモデルの有効性を確かめるために、比較対象としてコードシンボルを含め たモデルを作成し、コードシンボルを含めないモデルとの結果の比較を行った。評 価には、音楽的同時性と音楽的連続性の観点から客観評価と主観評価を用いて行っ た。結果として、コードシンボルを含めないモデルの結果で不協和音がわずかに 多くなってしまったが、コードシンボルを含まないモデルの結果の方が、豊富な 和音の種類の出現や、各声部の旋律やコード進行が滑らかになるなど、音楽的連 続性の観点において多くの点で優れていた。

description: We study the semigroup generated by the hypoelliptic Laplacian on the circle and the maximal bounded holomorphic extension of this semigroup. Using an orthogonal decomposition into harmonic oscillators with complex shifts, we describe the domain of this extension and we show that boundedness in a half-plane corresponds to absolute convergence of the expansion of the semigroup in eigenfunctions. This relies on a novel integral formula for the spectral projections which also gives asymptotics for Laguerre polynomials in a large-parameter regime.

description: A lengthy reflection and interpretation of six months of a grade seven, eight, and nine drama teacher's practice, the thesis focuses on the interpersonal relations between the teacher and her students. Using process drama as a foundation for developing knowledge of the self in the world, the pedagogy of this teacher also attempts to de-mystify the drama process for her students, and engage them in thoughtful presentational drama. In a series of ten stories interspersed with poetry and personal anecdotes, the topics of curriculum, assessment, professional development, drama pedagogy, and working and learning conditions are analyzed through a feminist, poststructuralist lens.

description: We construct $G_4$ fluxes that stabilize all of the 426 complex structure moduli of the sextic Calabi-Yau fourfold at the Fermat point. Studying flux stabilization usually requires solving Picard-Fuchs equations, which becomes unfeasible for models with many moduli. Here, we instead start by considering a specific point in the complex structure moduli space, and look for a flux that fixes us there. We show how to construct such fluxes by using algebraic cycles and analyze flat directions. This is discussed in detail for the sextic Calabi-Yau fourfold at the Fermat point, and we observe that there appears to be tension between M2-tadpole cancellation and the requirement of stabilizing all moduli. Finally, we apply our results to show that even though symmetric fluxes allow to automatically solve most of the F-term equations, they typically lead to flat directions.

description: The stochastic processes have greatly developed and their implementations appear in all the scientific areas. A key attribute of these processes is that the future system development depends on the present condition and not on the condition it was in the past.In this project there has been an attempt to define a jump process under a probability measure for a Poisson process and Compound Poisson process. It refers to jump processes and their integrals as well as the stochastic calculations of these processes. Furthermore there is a descrirption the matter of changing measures both for the Poisson and the Compound Poisson process.

description: Simulations of the random barrier model show that ac currents at extreme disorder are carried almost entirely by the percolating cluster slightly above threshold; thus contradicting traditional theories contributions from isolated low-activation-energy clusters are negligible. The effective medium approximation in conjunction with the Alexander-Orbach conjecture leads to an excellent analytical fit to the universal ac conductivity with no nontrivial fitting parameters.

description: We report the serendipitous discovery of a peculiar main sequence in archived Hubble Space Telescope WFPC2 observations of the young star cluster NGC 2011 in the Large Magellanic Cloud. The bright part of this main sequence exhibits a prominent double, fork-like feature, as if it consists of twin main sequences, one of them being redder. The color-magnitude diagram, constructed from the stars found in the only available WFPC2 field of the cluster, is used to distinguish the stars according to their membership to each of these sequences and to study their spatial distribution. We find that there are two well distinguished populations in the sense that the redder main sequence is dominated by stars that belong to the main body of the cluster, while the stars of the bluer main sequence belong to the surrounding region. Providing that NGC 2011 is a verified binary cluster, with the second companion unfortunately not observed, and taking into account the general region where this cluster is located, we discuss the possible scenarios from both star formation, and early dynamical evolution point-of-view that might explain this unique discovery.

description: The second paper of this series presents two robust entropy stable shock-capturing methods for discontinuous Galerkin spectral element (DGSEM) discretizations of the compressible magneto-hydrodynamics (MHD) equations. Specifically, we use the resistive GLM-MHD equations, which include a divergence cleaning mechanism that is based on a generalized Lagrange multiplier (GLM). For the continuous entropy analysis to hold, and due to the divergence-free constraint on the magnetic field, the GLM-MHD system requires the use of non-conservative terms, which need special treatment.

[DOI:10.1016/j.jcp.2020.109935] recently presented an entropy stable shock-capturing strategy for DGSEM discretizations of the Euler equations that blends the DGSEM scheme with a subcell first-order finite volume (FV) method. Our first contribution is the extension of the method of Hennemann et al. to systems with non-conservative terms, such as the GLM-MHD equations. In our approach, the advective and non-conservative terms of the equations are discretized with a hybrid FV/DGSEM scheme, whereas the visco-resistive terms are discretized only with the high-order DGSEM method. We prove that the extended method is entropy stable on three-dimensional unstructured curvilinear meshes. Our second contribution is the derivation and analysis of a second entropy stable shock-capturing method that provides enhanced resolution by using a subcell reconstruction procedure that is carefully built to ensure entropy stability. We provide a numerical verification of the properties of the hybrid FV/DGSEM schemes on curvilinear meshes and show their robustness and accuracy with common benchmark cases, such as the Orszag-Tang vortex and the GEM reconnection challenge. Finally, we simulate a space physics application: the interaction of Jupiter's magnetic field with the plasma torus generated by the moon Io.

description: We study the links between the topological complexity of an omega context free language and its degree of ambiguity. In particular, using known facts from classical descriptive set theory, we prove that non Borel omega context free languages which are recognized by Büchi pushdown automata have a maximum degree of ambiguity. This result implies that degrees of ambiguity are really not preserved by the operation of taking the omega power of a finitary context free language. We prove also that taking the adherence or the delta-limit of a finitary language preserves neither unambiguity nor inherent ambiguity. On the other side we show that methods used in the study of omega context free languages can also be applied to study the notion of ambiguity in infinitary rational relations accepted by Büchi 2-tape automata and we get first results in that direction.

description: The EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM) is a cryogenic balloon-borne instrument that will map carbon monoxide and singly-ionized carbon emission lines across redshifts from 0 to 3.5, using an intensity mapping approach. EXCLAIM will broaden our understanding of these elemental and molecular gases and the role they play in star formation processes across cosmic time scales. The focal plane of EXCLAIM's cryogenic telescope features six μ-Spec spectrometers. μ-Spec is a compact, integrated grating-analog spectrometer, which uses meandered superconducting niobium microstrip transmission lines on a single-crystal silicon dielectric to synthesize the grating. It features superconducting aluminum microwave kinetic inductance detectors (MKIDs), also in a microstrip architecture. The spectrometers for EXCLAIM couple to the telescope optics via a hybrid planar antenna coupled to a silicon lenslet. The spectrometers operate from 420 to 540 GHz with a resolving power R=λ/Δλ=512 and employ an array of 355 MKIDs on each spectrometer. The spectrometer design targets a noise equivalent power (NEP) of 2x10-18W/\sqrt{Hz} (defined at the input to the main lobe of the spectrometer lenslet beam, within a 9-degree half width), enabled by the cryogenic telescope environment, the sensitive MKID detectors, and the low dielectric loss of single-crystal silicon. We report on these spectrometers under development for EXCLAIM, providing an overview of the spectrometer and component designs, the spectrometer fabrication process, fabrication developments since previous prototype demonstrations, and the current status of their development for the EXCLAIM mission.

description: Let V be a symplectic vector space over a finite or local field. We compute the character of the Weil representation of the metaplectic group Mp(V). The final formulas are overtly free of choices (e.g. they do not involve the usual choice of a Lagrangian subspace of V). Along the way, in results similar to those of K. Maktouf, we relate the character to the Weil index of a certain quadratic form, which may be understood as a Maslov index. This relation also expresses the character as the pullback of a certain simple function from Mp(V\oplus V).

description: Digital technologies are changing the ways human rights are interfered and violated around the world and can be used to reinforce and reproduce racialized and gendered injustices and inequalities. Concerns has especially been raised on the impact of unregulated and exploitative digital technologies used to extract sensitive personal data from asylum seekers from the Global South by actors in the Global North. The European Union (EU) has been at the forefront in the development of digital technologies powered by artificial intelligence (AI) and is a strong proponent of digital solutions to “manage” migration. Thus, this has resulted in digital tools being involved in almost all aspects and processes in the current management of migration and asylum. While the past human rights implications of the “Fortress Europe” have been widely scrutinized and criticized, future ones, spurred on by the digital innovations and tools in the “Digital Fortress Europe”, needs to be examined. Although various systems and regulations are in place to protect asylum seekers when it comes to digital practices, for instance the ones governed through the Charter of Fundamental Rights of the European Union (CFR) and the European Union’s General Data Protection Regulation (GDPR), several weaknesses in the human rights protection of asylum seekers have been pointed out especially relating to this groups right to privacy, data protection, equality and non-discrimination. This thesis, therefore, aims to investigate the human rights implications and risks in the EU’s digital migration and border practices. Focus will be on the large-scale biometric database Eurodac, which has become one of the most important digital solutions in the current EU migration and asylum system. This database have received several concerns on its increased convergence between migration and terrorism, and its impact on asylum seekers. The proposed regulation of Eurodac has especially been worrisome regarding the seemingly weak protection of asylum seekers right to privacy, data protection as well equality and non-discrimination.

description: We prove in this paper that the length of the Wadge hierarchy of omega context free languages is greater than the Cantor ordinal epsilon_omega, which is the omega-th fixed point of the ordinal exponentiation of base omega. The same result holds for the conciliating Wadge hierarchy, defined by J. Duparc, of infinitary context free languages, studied by D. Beauquier. We show also that there exist some omega context free languages which are Sigma^0_omega-complete Borel sets, improving previous results on omega context free languages and the Borel hierarchy.

DNA damage

description: DNA is continuously attacked by both endogenous and exogenous damaging agents. The resulting DNA damage can play a significant role in mutagenesis and carcinogenesis. Though cells can experience up to 10⁵ DNA damaging events per day, they employ mechanisms including, base excision repair (BER) and translesion synthesis (TLS) to repair and bypass the DNA lesions, respectively. Evaluating the mechanisms by which cells respond to DNA damage provides insights to whether these lesions, though small and non-distorting, may be pro-mutagenic and lead to disease. Oxidative stress is ubiquitous and results in two major products, 8oxoA and 8oxoG. Using a supF-based mutation assay, we observed that the DNA lesion, 8oxoA, at frequencies as high as 19% in bacterial cells. Additionally, the mutational spectrum revealed the majority of mutations induced were A to C transversions supporting our previous data that dGTP will preferentially be inserted opposite oxoA. To investigate the repair of such oxidative damage, we solved the structure of 2’F-8oxoG in complex with a human oxoG DNA glycosylase (hOGG1). Use of the 2’F inhibited cleavage of the glycosidic bond and allowed us to visualize the DNA lesion in the active site of a catalytically competent glycosylase. Using this same supF assay, we evaluated the mutational frequencies 2’F-N7meG and its ring-opened product, 2’F-N7meFapyG. While replication across N7meFapyG was mutagenic, N7meG was not and our structure of N7meG with TLS polymerase, Dpo4, provided insights to how cells can accurately replicate across this DNA lesion. Lastly, we investigated the repair of DNA mismatches by Methyl-CpG-Binding Domain 4 (MBD4). Our structural and kinetic analysis highlights the significance of the elusive arginine finger in the recognition of a T:G mismatch.
Investigating intermediate teachers’ CDRom selection criteria

description: This study investigates the current selection criteria and processes that experienced intermediate educators (teachers, teacher librarians, technology teachers, teacher librarian/technology teachers, and teacher/technology teachers) in the Vancouver metropolitan area use to assess and evaluate CDROM software for use with intermediate students. The study was exploratory and descriptive in nature and employed a survey approach. The survey was administered using questionnaire and interview instruments. The questions for the study were developed through input from a panel of three CDROM experts, and further refined in a pilot study. The research instruments were administered by the researcher to twenty educators experienced with CDROM selection. During the interview, subjects were observed and tape recorded evaluating two CDROM encyclopedias. All audio recordings were transcribed. Content analysis of the interview transcriptions objectively, systematically, and quantitatively identified and described references to CDROM selection criteria, factors affecting the development of these selection criteria, and resources consulted when evaluating and selecting CDROM software. Subjects identified forty-six CDROM selection criteria, six factors influencing their evaluation and selection of CDROMs, and sixteen resources which they consulted when selecting CDROMs. It was found that groups of educators (e.g., teachers, teacher librarians, and technology teachers) differed on the types of selection criteria they used to evaluate CDROMs. Educators also used different criteria when evaluating a specific CDROM as opposed to criteria they listed for selecting all CDROMs. The recommendations for this study included: (a) ensuring educators are given time to preview, evaluate and test CDROMS with their students, (b) training educators how to select and use CDROM software in groups of educators both similar and different to their teaching specialties, (c) increasing the involvement of provincial and district resource specialists, and (d) the establishment of a previewing site on the internet to assist educators in their evaluation and selection of CDROM software.

description: The NANOGrav collaboration has recently observed first evidence of a gravitational wave background (GWB) in pulsar timing data. Here we explore the possibility that this GWB is due to new physics, and show that the signal can be well fit also with peaked spectra like the ones expected from phase transitions (PTs) or from the dynamics of axion like particles (ALPs) in the early universe. We find that a good fit to the data is obtained for a very strong PT at temperatures around 1 MeV to 10 MeV. For the ALP explanation the best fit is obtained for a decay constant of $F \approx 5\times 10^{17}$ GeV and an axion mass of $2\times 10^{-13}$ eV. We also illustrate the ability of PTAs to constrain the parameter space of these models, and obtain limits which are already comparable to other cosmological bounds.

description: We propose an observer for a SIR epidemic model. The observer is then uplifted into a predictor to compensate for time delays in the input and the output. Tuning criteria are given for tuning gains of the predictor, while the estimation-error stability is ensured using Lyapunov-Krasovskii functionals. The predictor's performance is evaluated in combination with a time-optimal control. We show that the predictor nearly recovers the performance level of the delay-free system.
