description: We present detections of absorption from the ground state and excited states of C I in the z = 1.9731 damped Ly\al\ system of the QSO 0013$-$004. The excitation temperature between the J = 0 and J = 1 fine-structure levels of C I is 11.6 $\pm$ 1.0 K. We estimate other contributions to the excitation of the C I fine-structure levels, and use the population ratio of the excited state to the ground state to derive an estimate for the cosmic microwave background radiation (CMBR) temperature of T = 7.9 $\pm$ 1.0 K at 0.61 mm and z = 1.9731, which is consistent with the predicted value of T = 8.105 $\pm$ 0.030 K from the standard cosmology.

Some family and friends also survived, but her mother, sisters and many other family members died in the Holocaust. This is as much their story as it is hers.
Richardson elements for parabolic subgroups of classical groups in positive characteristic

description: Let $G$ be a simple algebraic group of classical type over an algebraically closed field $k$. Let $P$ be a parabolic subgroup of $G$ and let $\p = \Lie P$ be the Lie algebra of $P$ with Levi decomposition $\p = ł\oplus \u$, where $\u$ is the Lie algebra of the unipotent radical of $P$ and $ł$ is a Levi complement. Thanks to a fundamental theorem of R. W. Richardson, $P$ acts on $\u$ with an open dense orbit; this orbit is called the {\em Richardson orbit} and its elements are called {\em Richardson elements}. Recently, the first author gave constructions of Richardson elements in the case $k = \C$ for many parabolic subgroups $P$ of $G$. In this note, we observe that these constructions remain valid for any algebraically closed field $k$ of characteristic not equal to 2 and we give constructions of Richardson elements for the remaining parabolic subgroups.

The standard mean-field treatment of inter-particle attraction in classical DFT is better than one might expect

description: In classical density functional theory (DFT) the part of the Helmholtz free energy functional arising from attractive inter-particle interactions is often treated in a mean-field or van der Waals approximation. On the face of it, this is a somewhat crude treatment as the resulting functional generates the simple random phase approximation (RPA) for the bulk fluid pair direct correlation function. We explain why using standard mean-field DFT to describe inhomogeneous fluid structure and thermodynamics is more accurate than one might expect based on this observation. By considering the pair correlation function $g(x)$ and structure factor $S(k)$ of a one-dimensional model fluid, for which exact results are available, we show that the mean-field DFT, employed within the test-particle procedure, yields results much superior to those from the RPA closure of the bulk Ornstein-Zernike equation. We argue that one should not judge the quality of a DFT based solely on the approximation it generates for the bulk pair direct correlation function.

description: Last week I attended the funeral of the widow (101 years old) of Major Allan Beckett, who designed the floating roadway for the Mulberry Harbours. The long roadways connected floating pier heads to allow the troops, equipment, and supplies to land successfully on D-Day.He also came up with the Kite Anchor, which could provide the necessary 30-ton restraint to secure the roadway and yet be light enough to be deployed without a mooring vessel. Two thousand anchors were made subsequently. There was a memorial to Allan's work unveiled by the local mayor and Lord Dannatt in 2009 on the 65th anniversary at Arromanches featuring a full-size replica of the anchor.There is also a beautiful large stained glass window at St. Peter's Church in Oare by Faversham, Kent, where he and now his widow are laid to rest. The window depicts a Mulberry tree, associated links to the harbour and anchor, and Allan's dates. It is well worth a visit.
Noncommutative spacetime symmetries from covariant quantum mechanics

description: In the last decades, noncommutative spacetimes and their deformed relativistic symmetries have usually been studied in the context of field theory, replacing the ordinary Minkowski background with an algebra of noncommutative coordinates. However, spacetime noncommutativity can also be introduced into single-particle covariant quantum mechanics, replacing the commuting operators representing the particle's spacetime coordinates with noncommuting ones. In this paper we provide a full characterization of a wide class of physically sensible single-particle noncommutative spacetime models and the associated deformed relativistic symmetries. In particular, we prove that they can all be obtained from the standard Minkowski model and the usual Poincaré transformations via a suitable change of variables. Contrary to previous studies, we find that spacetime noncommutativity does not affect the dispersion relation of a relativistic quantum particle, but only the transformation properties of its spacetime coordinates under translations and Lorentz transformations.

description: Non-linear dimensionality reduction (NDR) methods such as LLE and t-SNE are popular with visualization researchers and experienced data analysts, but present serious problems of interpretation. In this paper, we present DimReader, a technique that recovers readable axes from such techniques. DimReader is based on analyzing infinitesimal perturbations of the dataset with respect to variables of interest. The perturbations define exactly how we want to change each point in the original dataset and we measure the effect that these changes have on the projection. The recovered axes are in direct analogy with the axis lines (grid lines) of traditional scatterplots. We also present methods for discovering perturbations on the input data that change the projection the most. The calculation of the perturbations is efficient and easily integrated into programs written in modern programming languages. We present results of DimReader on a variety of NDR methods and datasets both synthetic and real-life, and show how it can be used to compare different NDR methods. Finally, we discuss limitations of our proposal and situations where further research is needed.

An analysis of soft terms in Calabi-Yau compactifications

description: We perform an analysis of the soft supersymmetry-breaking terms arising in Calabi-Yau compactifications. The sigma-model contribution and the instanton correction to the Kähler potential are included in the computation. The existence of off-diagonal moduli and matter metrics gives rise to specific features as the possibility of having scalars heavier than gauginos or the presence of tachyons. Although non-universal soft terms is a natural situation, we point out that there is an interesting limit where universality is achieved. Finally, we compare these results with those of orbifold compactifications. Although they are qualitatively similar some features indeed change. For example, sum rules found in orbifold models which imply that on average the scalars are lighter than gauginos can be violated in Calabi-Yau manifolds.

description: We present analytical results for the distribution of shortest path lengths (DSPL) in a network growth model which evolves by node duplication (ND). The model captures essential properties of the structure and growth dynamics of social networks, acquaintance networks and scientific citation networks, where duplication mechanisms play a major role. Starting from an initial seed network, at each time step a random node, referred to as a mother node, is selected for duplication. Its daughter node is added to the network, forming a link to the mother node, and with probability $p$ to each one of its neighbors. The degree distribution of the resulting network turns out to follow a power-law distribution, thus the ND network is a scale-free network. To calculate the DSPL we derive a master equation for the time evolution of the probability $P_t(L=\ell)$, $\ell=1,2,\dots$, where $L$ is the distance between a pair of nodes and $t$ is the time. Finding an exact analytical solution of the master equation, we obtain a closed form expression for $P_t(L=\ell)$. The mean distance, $\langle L \rangle_t$, and the diameter, $Δ_t$, are found to scale like $\ln t$, namely the ND network is a small world network. The variance of the DSPL is also found to scale like $\ln t$. Interestingly, the mean distance and the diameter exhibit properties of a small world network, rather than the ultrasmall world network behavior observed in other scale-free networks, in which $\langle L \rangle_t \sim \ln \ln t$.

Exploiting temporal information for 3D pose estimation

Year: 2017
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: In this work, we address the problem of 3D human pose estimation from a sequence of 2D human poses. Although the recent success of deep networks has led many state-of-the-art methods for 3D pose estimation to train deep networks end-to-end to predict from images directly, the top-performing approaches have shown the effectiveness of dividing the task of 3D pose estimation into two steps: using a state-of-the-art 2D pose estimator to estimate the 2D pose from images and then mapping them into 3D space. They also showed that a low-dimensional representation like 2D locations of a set of joints can be discriminative enough to estimate 3D pose with high accuracy. However, estimation of 3D pose for individual frames leads to temporally incoherent estimates due to independent error in each frame causing jitter. Therefore, in this work we utilize the temporal information across a sequence of 2D joint locations to estimate a sequence of 3D poses. We designed a sequence-to-sequence network composed of layer-normalized LSTM units with shortcut connections connecting the input to the output on the decoder side and imposed temporal smoothness constraint during training. We found that the knowledge of temporal consistency improves the best reported result on Human3.6M dataset by approximately $12.2\%$ and helps our network to recover temporally consistent 3D poses over a sequence of images even when the 2D pose detector fails.

description: The Whitehead minimization problem consists in finding a minimum size element in the automorphic orbit of a word, a cyclic word or a finitely generated subgroup in a finite rank free group. We give the first fully polynomial algorithm to solve this problem, that is, an algorithm that is polynomial both in the length of the input word and in the rank of the free group. Earlier algorithms had an exponential dependency in the rank of the free group. It follows that the primitivity problem -- to decide whether a word is an element of some basis of the free group -- and the free factor problem can also be solved in polynomial time.

description: We consider BPS-counting functions $\mathcal{Z}_{N,M}$ of $N$ parallel M5-branes probing a transverse $\mathbb{Z}_M$ orbifold geometry. These brane web configurations can be dualised into a class of toric non-compact Calabi-Yau threefolds which have the structure of an elliptic fibration over (affine) $A_{N-1}$. We make this symmetry of $\mathcal{Z}_{N,M}$ manifest in particular regions of the parameter space of the setup: we argue that for specific choices of the deformation parameters, the supercharges of the system acquire particular holonomy charges which lead to infinitely many cancellations among states contributing to the partition function. The resulting (simplified) $\mathcal{Z}_{N,M}$ can be written as a sum over weights forming a single irreducible representation of the Lie algebra $\mathfrak{a}_{N-1}$ (or its affine counterpart). We show this behaviour explicitly for an extensive list of examples for specific values of $(N,M)$ and generalise the arising pattern for generic configurations. Finally, for a particular compact M5-brane setup we use this form of the partition function to make the duality $N\leftrightarrow M$ manifest.

description: We used data from the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) to set upper-limits on the $γ$-ray and hard X-ray prompt emission associated with the gravitational wave event GW170104, discovered by the LIGO/Virgo collaboration. The unique omni-directional viewing capability of the instruments on-board INTEGRAL allowed us to examine the full 90% confidence level localization region of the LIGO trigger. Depending on the particular spectral model assumed and the specific position within this region, the upper limits inferred from the INTEGRAL observations range from F$γ$=1.9x10-7 erg cm-2 to F$γ$=10-6 erg cm-2 (75 keV - 2 MeV energy range). This translates into a ratio between the prompt energy released in $γ$-rays along the direction to the observer and the gravitational wave energy of E$γ$/EGW <2.6x10-5 . Using the INTEGRAL results, we can not confirm the $γ$-ray proposed counterpart to GW170104 by the AGILE team with the MCAL instrument. The reported flux of the AGILE/MCAL event, E2, is not compatible with the INTEGRAL upper limits within most of the 90% LIGO localization region. There is only a relatively limited portion of the sky where the sensitivity of the INTEGRAL instruments was not optimal and the lowest allowed fluence estimated for E2 would still be compatible with the INTEGRAL results. This region was also observed independently by Fermi/GBM and AstroSAT, from which, as far as we are aware, there are no reports of any significant detection of a prompt high-energy event.

description: Accessing difficult to reach hydrocarbon reservoirs while simultaneously reducing risk and increasing efficiency has driven demand for precise autonomous directional control of rotary steerable systems (RSS). Despite advances in RSS technology, precise control remains difficult primarily because the tool is located deep underground which introduces challenges that require advanced methods to overcome. In the deep subsurface environment, many parameters are difficult or impossible to measure. One consequence of this fact is model mismatch is often encountered which degrades control performance. Another consequence, resulting from the fact that the position of the tool cannot be measured underground, is that trajectory control is implemented on the surface imposing large communication delays on the control loop. This dissertation investigates methods to overcome these challenges and improve the accuracy and reliability of automated directional drilling. A Markov Chain Monte Carlo (MCMC) based method is proposed to estimate time-varying model parameters in real-time using only measurements commonly obtained while drilling. The method is evaluated on historical field data and in closed-loop simulation. Also, the utility of estimation for human-in-the-loop operation is explored through the design of an early warning system. In order to incorporate information of the model uncertainty into the control framework, a stochastic model predictive controller (SMPC) is designed. As part of this development, a series of approximations are made to a first-principles model of directional drilling that significantly reduces the computational complexity of the controller. The SMPC is posed as a convex second-order cone optimization problem that is solved efficiently and enables real-time directional control. In open-loop, the controller is optimal and satisfies state and input constraints probabilistically. In closed-loop, it satisfies input constraints, is approximately optimal, and has minimal violation of state constraints as demonstrated by simulation-based experiments. Lastly, to address the challenge of unobservable position downhole, a machine learning (ML) based estimation method is developed, and several algorithms are compared in terms of accuracy and computational demand, which is critical to practical implementation. The impact of estimation errors on control performance is analyzed, and the results are used as metrics in the evaluation of the models on historical drilling data.

description: Over the past few decades, Moore’s Law has been a driving force behind the exponential increase in integrated circuits capabilities, significantly transforming people’s lives. However, the continuation of Moore’s Law is being called into question as the continuous shrinking of electric circuits is approaching physical limitations. Currently, the size of transistors and interconnects, two fundamental components in modern chips, has reached the tens of nanometers. Further downscaling leads to circuit delay, heat dissipation and poor performance of microchips, ultimately prohibiting Moore’s Law. One of the biggest challenges is the materials: conventional semiconductors and metals in transistors and interconnects exhibit undesirable resistivity increases when reduced to the nanoscale. Thus, the need for 2D semiconductors and better metals with fewer dimensional impacts has become increasingly urgent. This underscores the critical importance of understanding electronic transport in small system, which is the focus of this thesis. By utilizing first-principles calculations, the mobility and conductivity of 2D semiconductors and finite-size metals can be predicted, leading to physical insights and high-throughput screening for best candidates for electronic transport. This dissertation is organized as follows: Chapter 2 describes the Boltzmann transport equation (BTE) to study electronic transport in materials. Chapter 3 demonstrates how to obtain the transition rates, necessary for solving the BTE, from first principles. In particular, we developed an efficient approach to interpolate the electron-phonon-coupling matrix in 2D materials, which can also include the effect of free carrier screening. Based on the state-of-the-art calculations, Chapter 4 shows that reduced dimensionality results in a larger “density of scattering” in 2D semiconductors, leading to generally lower carrier mobility. We predict several high-mobility (>1400 cm²V⁻¹s⁻¹) 2D semiconductors with extremely small effective mass and/or weak EPC, thus avoiding the “dimensional curse”. Chapter 5 and 6 demonstrate the computational approaches to high-field transport properties and remote phonon scattering for 2D semiconductors, respectively. Finally, for metal in interconnects, we develop an ab initio approach to incorporating electron-phonon/surface scattering for electronic transport in finite-size metals and demonstrated it in copper films with different surfaces in Chapter 7.

description: We study cosmological solutions in nonlocal teleparallel gravity or $f(T)$ theory, where $T$ is the torsion scalar in teleparallel gravity. This is a natural extenstion of the usual teleparallel gravity with nonlocal terms. In this work the phase space portrait proposed to describe the dynamics of an arbitrary flat, homogeneous cosmological background with a number of matter contents, both in early and late time epochs. The aim was to convert the system of the equations of the motion to a first order autonomous dynamical system and to find fixed points and attractors using numerical codes. For this purpose, firstly we derive effective forms of cosmological field equations describing the whole cosmic evolution history in a homogeneous and isotropic cosmological background and construct the autonomous system of the first order dynamical equations. In addition, we investigate the local stability in the dynamical systems called "the stable/unstable manifold" by introducing a specific form of the interaction between matter, dark energy, radiation and a scalar field. Furthermore, we explore the exact solutions of the cosmological equations in the case of de Sitter spacetime. In particular, we examine the role of an auxiliary function called "gauge" $η$ in the formation of such cosmological solutions and show whether the de Sitter solutions can exist or not. Moreover, we study the stability issue of the de Sitter solutions both in vacuum and non-vacuum spacetimes. It is demonstrated that for nonlocal $f(T)$ gravity, the stable de Sitter solutions can be produced even in vacuum spacetime.

description: Given the implications of the COVID-19 pandemic on vulnerable and marginalized communities, it is essential that the unique implications of additional significant life stressors for Black women and birthing communities are carefully considered. These implications include addressing the complex intersectionality of pregnancy, gender, race, and social class and how structural inequalities which existed before the pandemic have been magnified in the COVID-19 era. Guided by an adapted stress process model, Black feminist thought, and the reproductive justice framework, this dissertation sought to qualitatively explore the lived and observed experiences of stress and perinatal care among Black mothers (Study 1; n=35) and maternity care professionals (Study 2; n=29) during the COVID-19 pandemic. Following a qualitative descriptive research design, in‐depth, semi-structured, virtual interviews were conducted with a total of 64 individuals between May and August of 2022. For Study 1, mothers recounted experiences of discrimination stress, trauma, support, and well-being as it related to the stigmas around their pregnancies and evolving motherhood. For Study 2, in addition to providing sentiments that validated the perinatal experiences shared by Black mothers in Study 1, maternity care professionals reflected on their journeys to, challenges of, and outlook for birthwork, including implications for Black maternal health. In addition to prompting dramatic changes to the delivery of maternal healthcare in the United States, findings from this dissertation have highlighted major dimensions of well-being, safety, and respectful maternity care described by Black mothers and care practitioners. Therefore, Future research should continue to center the experiences of Black mothers and include the voices of birthwork professionals around their roles in Black birth justice and maternal health equity.

description: X-ray emission is one of the signposts of circumstellar interaction in supernovae (SNe), but until now, it has been observed only in core-collapse SNe. The level of thermal X-ray emission is a direct measure of the density of the circumstellar medium (CSM), and the absence of X-ray emission from Type Ia SNe has been interpreted as a sign of a very low density CSM. In this paper, we report late-time (500--800 days after discovery) X-ray detections of SN 2012ca in {\it Chandra} data. The presence of hydrogen in the initial spectrum led to a classification of Type Ia-CSM, ostensibly making it the first SN~Ia detected with X-rays. Our analysis of the X-ray data favors an asymmetric medium, with a high-density component which supplies the X-ray emission. The data suggest a number density $> 10^8$ cm$^{-3}$ in the higher-density medium, which is consistent with the large observed Balmer decrement if it arises from collisional excitation. This is high compared to most core-collapse SNe, but it may be consistent with densities suggested for some Type IIn or superluminous SNe. If SN 2012ca is a thermonuclear SN, the large CSM density could imply clumps in the wind, or a dense torus or disk, consistent with the single-degenerate channel. A remote possibility for a core-degenerate channel involves a white dwarf merging with the degenerate core of an asymptotic giant branch star shortly before the explosion, leading to a common envelope around the SN.

description: Quasi-simultaneous optical/near-IR photometry is presented for a sample of 37 luminous optically selected QSOs drawn from the Large Bright QSO Survey. Most of the QSOs have decreased in brightness since discovery; this is expected in flux-limited samples. The continuum shape of most of the QSOs can be represented by a power-law of the form F(nu) = nu**-0.3, but a few have softer (redder) continuum slopes.

description: In the framework of Anisotropic Chromo Dynamics, a non-perturbative model of QCD based on magnetic condensation in the vacuum, we develope a picture of the Pomeron. Within this model we are able to calculate the diffractive contribution to deep inelastic scattering in the small Bjorken x region, actually probed at Hera. We calculate the diffractive structure function of the proton and make the comparison with the experimental data of Zeus and H1 collaborations. Good agreement with the experimental data, both for the diffractive structure function $F_2^D$ and for the ''structure function'' of the Pomeron, is achieved.

Nonparametric econometrics
Identification

description: This dissertation consists of three chapters on applied econometrics and econometric theory. The first two chapters propose new estimating approaches to nonparametric production functions, and the third chapter studies the partial identification of treatment effects in a nonparametric setting. In the first chapter, we study the nonparametric identification of gross output production functions with a nonseparable productivity shock when output markets are perfectly competitive. Our nonseparable specification relaxes the traditional assumption of Hicks neutrality that has been shown to be inconsistent with a number of data sets. It can thus capture the bias in technical change, which recent research has found relevant to many important economic questions. We first generalize the identification approach of Gandhi et al. (2020) to nonseparable models and show the identification of output elasticities. To identify the entire production function, we then impose a homogeneity assumption, which is supported by the data. Given the fact that our nonseparable models nest Hicks-neutral models, we are able to document the misspecification bias of the latter. Using Chilean and Colombian plant-level data, our estimates suggest that Hicks-neutral models overestimate returns to scale, overestimate output elasticities of labor, and generate biased estimates of capital intensity. Our estimates also indicate that technological change is predominantly biased toward capital over labor and intermediate inputs. In the second chapter, we extend the identification approach in chapter 1 from perfect competition to imperfect competition. When physical quantities of output are observed, we follow Flynn et al. (2019) and replace the assumption of perfect competition with a constant-returns-to-scale (CRS) condition. When only revenue instead of physical output is observed, we follow Kasahara and Sugita (2020) and combine a first-order condition with a CRS condition to show identification of output elasticities and markups. In the third chapter, we derive a set of partial identification results for the mean treatment response and the average treatment effect when the μ-strong concavity assumption is combined with the monotone treatment response (MTR) assumption or the MTR-MTS (monotone treatment selection) assumption. μ-strong concavity is a generalization of the usual concavity assumption and the parameter μ can be seen as a measure of the strength of concavity. By tuning the value of the parameter μ, a practitioner can conduct sensitivity analyses with respect to the concavity assumption. We illustrate my findings by reanalyzing the return to schooling example of Manski and Pepper (2000).

description: My father, Neville Edwards, was part of 38 Group RAF and towards the end of the war was stationed in Holland. With a few hours to kill before the next push forward, he and a couple of mates borrowed a dinghy from one of the aircraft and paddled up a canal (river?) next to a Displaced Persons camp. They stopped to chat to the inmates through the wire fence and one of them offered Neville a cigarette case in return for some cigarettes. The man told them that terrible things were going on at the camp and pleaded with them to report it to their superior officers as soon as they got back, which they did.Neville always maintained that, as far as he knew, nothing was done about it and as they passed the camp the next day they were told that one of the inmates had been hung.My father kept this cigarette case for his entire life (he died in 2017). The name engraved on the case is "Wachtm Magers 1945" (see photos for detail).
