description: The mass distribution of compact objects provides a fossil record that can be studied to uncover information on the late stages of massive star evolution, the supernova explosion mechanism, and the dense matter equation of state. Observations of neutron star masses indicate a bimodal Gaussian distribution, while the observed black hole mass distribution decays exponentially for stellar-mass black holes. We use these observed distributions to directly confront the predictions of stellar evolution models and the neutrino-driven supernova simulations of Sukhbold et al. (2016). We find excellent agreement between the black hole and low-mass neutron star distributions created by these simulations and the observations. We show that a large fraction of the stellar envelope must be ejected, either during the formation of stellar-mass black holes or prior to the implosion through tidal stripping due to a binary companion, in order to reproduce the observed black hole mass distribution. We also determine the origins of the bimodal peaks of the neutron star mass distribution, finding that the low-mass peak (centered at ~1.4 M_sun) originates from progenitors with M_zams ~ 9-18 M_sun. The simulations fail to reproduce the observed peak of high-mass neutron stars (centered at ~1.8 M_sun) and we explore several possible explanations. We argue that the close agreement between the observed and predicted black hole and low-mass neutron star mass distributions provides new promising evidence that these stellar evolution and explosion models are accurately capturing the relevant stellar, nuclear, and explosion physics involved in the formation of compact objects.

Observations of white-light flares in NOAA active region 11515: high occurrence rate and relationship with magnetic transients

description: There are two goals in this study. One is to investigate how frequently white-light flares (WLFs) occur in a flare-productive active region (NOAA active region 11515). The other is to investigate the relationship between WLFs and magnetic transients (MTs). We use the full-disk continuum filtergrams and line-of-sight magnetograms taken by SDO/HMI to identify WLFs and MTs, respectively. Images taken by SDO/AIA are also used to show the morphology of the flares in the upper atmosphere. We found at least 20 WLFs out of a total of 70 flares above C class (28.6%) in NOAA active region 11515 during its passage across the solar disk. Each of these WLFs occurred in a small region, with a short duration of about 5 minutes. The enhancement of white-light continuum intensity is usually small, with an average enhancement of 8.1%. The 20 WLFs observed were found along an unusual configuration of the magnetic field characterized by a narrow ribbon of negative field. Furthermore, the WLFs were found to be accompanied by MTs, with radical changes in magnetic field strength (or even a sign reversal) observed during the flare. In contrast, there is no obvious signature of MTs in those 50 flares without white-light enhancements. Our results suggest that WLFs occur much more frequently than what was previously thought, with most WLFs being fairly weak enhancements. This may explain why WLFs are not frequently reported. Our observations also suggest that MTs and WLFs are closely related and appear co-spatial and co-temporal, when considering HMI data. A larger enhancement of WL emission is often accompanied by a larger change of the line-of-sight component of the unsigned magnetic field. Considering the close relationship between MTs and WLFs, many previously reported flares with MTs may be WLFs.

High-energy strong interactions: from `hard' to `soft'

description: We discuss the qualitative features of the recent data on multiparticle production observed at the LHC. The tolerable agreement with Monte Carlos based on LO DGLAP evolution indicates that there is no qualitative difference between `hard' and `soft' interactions; and that a perturbative QCD approach may be extended into the soft domain. However, in order to describe the data, these Monte Carlos need an additional infrared cutoff k_min with a value k_min ~ 2-3 GeV which is not small, and which increases with collider energy. Here we explain the physical origin of the large k_min. Using an alternative model which matches the `soft' high-energy hadron interactions smoothly on to perturbative QCD at small x, we demonstrate that this effective cutoff k_min is actually due to the strong absorption of low k_t partons. The model embodies the main features of the BFKL approach, including the diffusion in transverse momenta, lnk_t, and an intercept consistent with resummed next-to-leading log corrections. Moreover, the model uses a two-channel eikonal framework, and includes the contributions from the multi-Pomeron exchange diagrams, both non-enhanced and enhanced. The values of a small number of physically-motivated parameters are chosen to reproduce the available total, elastic and proton dissociation cross section (pre-LHC) data. Predictions are made for the LHC, and the relevance to ultra-high-energy cosmic rays is briefly discussed. The low x inclusive integrated gluon PDF, and the diffractive gluon PDF, are calculated in this framework, using the parameters which describe the high-energy pp and p\bar{p} `soft' data. Comparison with the PDFs obtained from the global parton analyses of deep inelastic and related `hard' scattering data, and from diffractive deep inelastic data looks encouraging.

description: This paper examines the existence of the self-intersection local time for a superprocess over a stochastic flow in dimensions $d\leq3$, which through constructive methods, results in a Tanaka-like representation. The superprocess over a stochastic flow is a superprocess with dependent spatial motion, and thus Dynkin's proof of existence, which requires multiplicity of the log-Laplace functional, no longer applies. Skoulakis and Adler's method of calculating moments is extended to higher moments, from which existence follows.

Commencement

description: Motivational speeches take a myriad of forms. Commencement speeches serve a niche within that genre – an opportunity for highly successful individuals to deliver wisdom about life to young adults entering the next stages of their lives. Modern day speakers range from politicians, to entertainers, to athletes, and more. Each speaker brings a different message and method; all serve critical roles in revered commencement ceremonies. This thesis explores commencement speeches in three ways. First, it explains the history of these speeches and how they evolved from 1642 to 2021. Next, it analyzes the individuals delivering the addresses, as well as the university administrators who select them. Finally, it develops case studies of successful speeches – identifying what components of the speech left an impact, and what components fell flat. I conclude the thesis by delivering my own commencement address text to fellow Spring 2021 Plan II graduates – borrowing strategies from the legendary speakers that came before me.

description: We investigate the spectral functions of the Higgs mode in $O(2)$ model, which can be experimentally realized in a 2D Bose gas. Zero temperature limit is considered. Our calculation fully includes the 2-loop contributions. Peaks show up in the spectral functions of both the longitudinal and the scalar susceptibilities. Thus this model cannot explain the disappearance of the response at the weak interaction limit. Neither it can explain the similarity between the longitudinal and the scalar susceptibilities in the visibility of the Higgs mode. A possible lower peak at about $2m_σ$ is also noted.

description: We report the discovery of WASP-3b, the third transiting exoplanet to be discovered by the WASP and SOPHIE collaboration. WASP-3b transits its host star USNO-B1.0 1256-0285133 every 1.846834+-0.000002 days. Our high precision radial-velocity measurements present a variation with amplitude characteristic of a planetary-mass companion and in-phase with the light-curve. Adaptive optics imaging shows no evidence for nearby stellar companions, and line-bisector analysis excludes faint, unresolved binarity and stellar activity as the cause of the radial-velocity variations. We make a preliminary spectroscopic analysis of the host star finding it to have Teff = 6400+-100 K and log g = 4.25+-0.05 which suggests it is most likely an unevolved main sequence star of spectral type F7-8V. Our simultaneous modelling of the transit photometry and reflex motion of the host leads us to derive a mass of 1.76 +0.08 -0.14 M_J and radius 1.31 +0.07-0.14 R_J for WASP-3b. The proximity and relative temperature of the host star suggests that WASP-3b is one of the hottest exoplanets known, and thus has the potential to place stringent constraints on exoplanet atmospheric models.

description: We have performed a calculation of the scattering amplitude for the three body system $\bar{K}NN$ assuming $\bar{K}$ scattering against a $NN$ cluster, using the Fixed Center approximation to the Faddeev equations. The $\bar{K}N$ amplitudes, which we take from chiral unitary dynamics, govern the reaction and we find a $\bar{K}NN$ amplitude that peaks around 40 MeV below the $\bar{K}NN$ threshold, with a width in $|T|^2$ of the order of 50 MeV for spin 0 and has another peak around 27 MeV with similar width for spin 1. The results are in line with those obtained using different methods but implementing chiral dynamics. The simplicity of the approach allows one to see the important ingredients responsible for the results. In particular we show the effects from the reduction of the size of the $NN$ cluster due to the interaction with the $\bar{K}$ and those from the explicit considiration of the $ πΣN $ channel in the three body equations.

Oral Histories of Disaster and Resistance at the Dos Repúblicas Mine in Eagle Pass, Texas

Publisher: name: The University of Texas at Austin
Year: 2021
Subjects: Eagle Pass

description: After thirty years of opposition to the Dos Repúblicas coal mine in Eagle Pass, Texas, this project intends to uncover the multiple and interrelated ways in which community residents, grassroots organizers, and Indigenous environmental justice activists sought to prevent and later shut down this mine. These methods of mitigating the mine’s damage focused on attempting to control narratives of how the mine impacted people and the environment and who was considered in the wake of its impact, specifically, who was considered Indigenous and therefore had special rights in protecting sacred sites. Understanding these methods of articulation and rearticulation of individual and group identity relies on framing the histories of Indigenous peoples living and later being assimilated into Spanish and Anglo settlements, historical coal mining development projects spanning the U.S.-Mexico divide, and the U.S. federal government’s legal relationship to Indigenous peoples across the country. Oral history interviews provide a foundational interpretation of how individuals and communities positioned themselves in response to two primary narratives: the totalizing narratives embedded in federal recognition and the narratives of environmental and human harm that relied on manipulation of scientific data by state and federal agencies. As these two narratives are deeply connected and rely on one another, alliances between grassroots environmental activists and Indigenous environmental justice activists were embedded in organizing against the mine from the start. These oral history interviews revealed the perception among Eagle Pass residents of their own racialization, as evidenced by state and federal agencies neglect; conversely, the interviews point to how residents want to be seen as a community transitioning away from its coal mining history, highlighting the ways in which the land and waters are uniquely and differently held as precious by communities across the state. The interviews also speak to demands for visibility among unrecognized Indigenous nations in the state and the maneuvers of Indigenous nations to circumvent limitations of federal recognition through environmental justice organizing.

A phenomenological scaling behavior of rapidity dependent flow parameters $v_n$ (n = 1, 2, 3 and 4) has been found as a function of mass number plus a constant term, which may arise from the interplay of collective and random motions. In addition, $v_4/{v_2}^2$ keeps almost independent of rapidity and remains a rough constant of 1/2 for all light fragments.

description: This study evaluates the U.S. healthcare system through the interactions of care, business and policy as modeled by the ability of hospitals to remain financially viable in lieu of healthcare reform under the Patient Protection and Affordable Care Act and the proceeding non-enforcement of the individual mandate of insurance. To do so, I develop historical and political context in respect to each of the three functions of U.S. healthcare (care, business and policy) for hospitals and their interactions with the individual insurance mandate. In order to evaluate this interaction, I use a difference-in-difference empirical model to measure the changes in hospital financial stability after non-enforcement of the individual insurance mandate in Massachusetts and Connecticut. In combining these various approaches and analysis to evaluate the functions of the U.S. healthcare system, the ineffective aspects of the system will be identified, thus providing insight for improving U.S. health outcomes and optimizing health spending.

description: We present the theory of an extremely correlated Fermi liquid (ECFL) with $U\to \infty$. This liquid has an underlying Fermi liquid (FL) Greens function that is further caparisoned. The theory leads to two parallel hierarchies of equations that permit iterative approximations in a certain parameter. Preliminary results for the spectral functions display a broad background and a distinct $T$ dependent left skew. An important energy scale $Δ(\vec{k},x)$ emerges as the average inelasticity of the FL Greens function, and influences the photoemission spectra profoundly. A duality is identified wherein an apparent loss of coherence of the ECFL results from an excessively sharp FL.

description: We present a semi-supervised co-analysis method for learning 3D shape styles from projected feature lines, achieving style patch localization with only weak supervision. Given a collection of 3D shapes spanning multiple object categories and styles, we perform style co-analysis over projected feature lines of each 3D shape and then backproject the learned style features onto the 3D shapes. Our core analysis pipeline starts with mid-level patch sampling and pre-selection of candidate style patches. Projective features are then encoded via patch convolution. Multi-view feature integration and style clustering are carried out under the framework of partially shared latent factor (PSLF) learning, a multi-view feature learning scheme. PSLF achieves effective multi-view feature fusion by distilling and exploiting consistent and complementary feature information from multiple views, while also selecting style patches from the candidates. Our style analysis approach supports both unsupervised and semi-supervised analysis. For the latter, our method accepts both user-specified shape labels and style-ranked triplets as clustering constraints.We demonstrate results from 3D shape style analysis and patch localization as well as improvements over state-of-the-art methods. We also present several applications enabled by our style analysis.

Lecane bulla
(figures 1, 2, 4)
Body consists of three regions: a retractile head, trunk and foot. The head is short, and bears a simple, slightly oblique anterior corona and dorsal antenna (not drawn). A single large, red cerebral eye is present. The trunk is more or less cylindrical with a weakly developed lorica, separated in a ventral and dorsal plate, and pleural membranes with the apertures to the lateral antennae. The lorica plates are relatively soft hence easily distorted. The digestive system is vestigial. The single testicle is large, with two prostate glands. Dorsal to the testicle is a vesicle fi lled with glassy concretions. The foot is weakly bent ventrad and has four pseudosegments, the distal one the longest. The foot contains the penis and a ciliated vas deferens, the gonopore lies between the third and fourth foot pseudosegment. There are two completely separated and mobile toes bearing pseudoclaws and accessory claws.
Measurements (in μ m, of a single fully extended specimen): total length 143, trunk length 68, height 38, width 49. Toes 22, pseudoclaws 5. Of corresponding female: dorsal plate length 141, width 109, ventral plate length 146, width 109, toe length 84, pseudoclaw length 21.
Behaviour and reproduction
No significant differences were observed between the swimming speed of male and female L. bulla, expressed either in BL s Õ 1 (male: 2.38, SD = 0.87, female: 1.57, SD = 0.73; n =10) or mm s Õ 1 (male: 0.43, SD = 0.17, female: 0.36, SD = 0.16; n = 10). Copulation occurs by penetration of the penis through the female integument of the pleural membrane. Only one resting egg is produced per female (figure 3), this egg is not deposited but remains inside the lorica of the female, which dies after production of the egg. The resting egg shell is thick and has an alveolar structure.

description: The quantum space-time and the phase space with fuzzy structure is investigated as the possible quantization formalism. In this theory the state of nonrelativistic particle corresponds to the element of fuzzy ordered set (Foset) - fuzzy point. Due to Foset partial (weak) ordering, particle's space coordinate x acquires principal uncertainty dx. It's shown that Shroedinger formalism of Quantum Mechanics can be completely derived from consideration of particle evolution in fuzzy phase space with minimal number of axioms.

description: The recent observation of the pulsar PSR J1614-2230 with a mass of 1.97 +/- 0.04 M_sun gives a strong constraint on the quark and nuclear matter equations of state (EoS). We explore the parameter ranges for a parameterized EoS for quark stars. We find that strange stars, made of absolutely stable strange quark matter, comply with the new constraint only if effects from the strong coupling constant and color-superconductivity are taken into account. Hybrid stars, compact stars with a quark matter core and an hadronic outer layer, can be as massive as 2 M_sun, but only for a significantly limited range of parameters. We demonstrate that the appearance of quark matter in massive stars depends crucially on the stiffness of the nuclear matter EoS. We show that the masses of hybrid stars stay below the ones of hadronic and pure quark stars, due to the softening of the EoS at the quark-hadron phase transition.

description: Hydroxyl (OH) is expected to be abundant in diffuse interstellar molecular gas as it forms along with $H_2$ under similar conditions and within a similar extinction range. We have analyzed absorption measurements of OH at 1665 MHz and 1667 MHz toward 44 extragalactic continuum sources, together with the J=1-0 transitions of $^{12}$CO, $^{13}$CO , and C$^{18}$O, and the J=2-1 of $^{12}$CO. The excitation temperature of OH were found to follow a modified log-normal distribution, $ f(T{\rm_{ex}}) \propto \frac{1}{ \sqrt{2π}σ} \rm{exp}\left[-\frac{[ln(\textit{T}_{ex})-ln(3.4\ K)]^2}{2σ^2}\right] $, the peak of which is close to the temperature of the Galactic emission background (CMB+synchron). In fact, 90% of the OH has excitation temperature within 2 K of the Galactic background at the same location, providing a plausible explanation for the apparent difficulty to map this abundant molecule in emission. The opacities of OH were found to be small and peak around 0.01. For gas at intermediate extinctions (A$\rm_V$ $\sim$ 0.05-2 mag), the detection rate of OH with detection limit $N(\mathrm{OH})\simeq 10^{12}$ cm$^{-2}$ is approximately independent of $A\rm_V$. We conclude that OH is abundant in the diffuse molecular gas and OH absorption is a good tracer of `dark molecular gas (DMG)'. The measured fraction of DMG depends on assumed detection threshold of the CO data set. The next generation of highly sensitive low frequency radio telescopes, FAST and SKA, will make feasible the systematic inventory of diffuse molecular gas, through decomposing in velocity the molecular (e.g. OH and CH) absorption profiles toward background continuum sources with numbers exceeding what is currently available by orders of magnitude.

Scenario-based optimization of merchant vessels
Creators: name: Wagner, Jonas Conradin
Publisher: name: Universität Rostock
Year: 2017
Subjects: subject: 620 Engineering & allied operations

description: This thesis introduces a scenario approach for determining a vessel's future operational profile regarding speed, draught and sea state conditions. It follows the Monte-Carlo principle and features the multiple simulation of a vessel's service life on the basis of a designated trade description, stochastically developing economic and market conditions and environmental influences. Additionally, uncertainties and disruptive events (crises) are considered. The resulting operational profile provides the basis for a multi-objective hull form optimization leading to a robust, holistic ship design.

description: We analyze the behavior of the longitudinal conductivity $σ_{zz}$ in a field perpendicular to the highly conducting plane of a quasi-2D {\em multiband} metal in the case of closed system and open systems where $τ$ is fixed, $τ$ oscillates due to intra-band scattering and $τ$ oscillates due to inter-band scattering. In all but one case, we find that there are also mixing frequencies present -- however they exhibit different qualitative behaviors, as befits their different origins, and in the case of inter-band scattering in an opensystem, may in fact be absent in the dHvA oscillations of that system.

Long-time Asymptotics for Nonlinear Growth-fragmentation Equations

Publisher: name: arXiv
Year: 2011
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: We are interested in the long-time asymptotic behavior of growth-fragmentation equations with a nonlinear growth term. We present examples for which we can prove either the convergence to a steady state or conversely the existence of periodic solutions. Thanks the General Relative Entropy method applied to well chosen self-similar solutions, we show that the equation can "asymptotically" be reduced to a system of ODEs. Then stability results are proved by using a Lyapunov functional, and existence of periodic solutions are proved thanks to the Poincaré-Bendixon theorem or by Hopf bifurcation.

description: The dynamics of finite temperature U(N) gauge theories on $S^3$ can be described, at weak coupling, by an effective unitary matrix model. Here we present an exact solution to these models, for any value of $N$, in terms of a sum over representations. Taking the large $N$ limit of this solution provides a new perspective on the deconfinement transition which is supposed to be dual to the Hawking-Page transition. The large $N$ phase transition manifests itself here in a manner similar to the Douglas-Kazakov phase transition in 2d Yang-Mills theory. We carry out a complete analysis of the saddle representation in the simplest case involving only the order parameter ${\rm Tr}U$. We find that the saddle points corresponding to thermal $AdS$, the small black hole and the large black hole can all be described in terms of free fermions. They all admit a simple phase space description {\it a la} the BPS geometries of Lin, Lunin and Maldacena.

Calorimeter Assisted Tracking Algorithm for SiD
Creators: name: Onoprienko, Dmitry
name: von Toerne, Eckhard
Publisher: name: arXiv
Year: 2007
Subjects: subject: Instrumentation and Detectors (physics.ins-det)
subject: FOS: Physical sciences

description: Calorimeter-assisted track finding algorithm takes advantage of the finely segmented electromagnetic calorimeter proposed for the SiD detector concept by looking for "MIP stubs" produced by charged particles in the calorimeter, and using them as seeds for pattern recognition in the tracker. The algorithm allows for efficient reconstruction of tracks that cannot be found using seeds provided by the vertex detector, even if standalone pattern recognition in the outer tracker is difficult. The algorithm has been implemented as a package in the org.lcsim framework. Current status of the package and its performance in non-prompt tracks reconstruction are described.

Average Biased ReLU Based CNN Descriptor for Improved Face Retrieval
Creators: name: Dubey, Shiv Ram
name: Chakraborty, Soumendu
Publisher: name: arXiv
Year: 2018
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: The convolutional neural networks (CNN), including AlexNet, GoogleNet, VGGNet, etc. extract features for many computer vision problems which are very discriminative. The trained CNN model over one dataset performs reasonably well whereas on another dataset of similar type the hand-designed feature descriptor outperforms the same trained CNN model. The Rectified Linear Unit (ReLU) layer discards some values in order to introduce the non-linearity. In this paper, it is proposed that the discriminative ability of deep image representation using trained model can be improved by Average Biased ReLU (AB-ReLU) at the last few layers. Basically, AB-ReLU improves the discriminative ability in two ways: 1) it exploits some of the discriminative and discarded negative information of ReLU and 2) it also neglects the irrelevant and positive information used in ReLU. The VGGFace model trained in MatConvNet over the VGG-Face dataset is used as the feature descriptor for face retrieval over other face datasets. The proposed approach is tested over six challenging, unconstrained and robust face datasets (PubFig, LFW, PaSC, AR, FERET and ExtYale) and also on a large scale face dataset (PolyUNIR) in retrieval framework. It is observed that the AB-ReLU outperforms the ReLU when used with a pre-trained VGGFace model over the face datasets. The validation error by training the network after replacing all ReLUs with AB-ReLUs is also observed to be favorable over each dataset. The AB-ReLU even outperforms the state-of-the-art activation functions, such as Sigmoid, ReLU, Leaky ReLU and Flexible ReLU over all seven face datasets.

description: Single crystal neutron diffraction study has been performed on new superconductor A2Fe4Se5, where A = Cs, K, (Tl,Rb) and (Tl,K), and the same Fe vacancy ordered crystal structure and the same block checkerboard antiferromagne tic order recently discovered in the K2Fe4Se5 superconductor are observed. Thus, all known alkali metal and/or Tl intercalated iron selenide superconductors share common crystalline and magnetic structure. Investigation on electronic process in these new superconductors, for which a different electronic structure from those in previous Fe-based high-Tc superconductors is emerging, now has a valid structural and magnetic framework.

Critical Current Calculations For Long $0$-$π$ Josephson Junctions
Creators: name: Tornes, Ivan

Year: 2007
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: A zigzag boundary between a $d_{x^2-y^2}$ and an $s$-wave superconductor is believed to behave like a long Josephson junction with alternating sections of $0$ and $π$ symmetry. We calculate the field-dependent critical current of such a junction, using a simple model. The calculation involves discretizing the partial differential equation for the phase difference across a long $0$-$π$ junction. In this form, the equations describe a hybrid ladder of inductively coupled small $0$ and $π$ resistively and capacitively shunted Josephson junctions (RCSJ's). The calculated critical critical current density $J_c(H_a)$ is maximum at non-zero applied magnetic field $H_a$, and depends strongly on the ratio of Josephson penetration depth $λ_J$ to facet length $L_f$. If $λ_J/L_f \gg 1$ and the number of facets is large, there is a broad range of $H_a$ where $J_c(H_a)$ is less than $2\%$ of the maximum critical current density of a long $0$ junction. All of these features are in qualitative agreement with recent experiments. In the limit $λ_J/L_f \to \infty$, our model reduces to a previously-obtained analytical superposition result for $J_c(H_a)$. In the same limit, we also obtain an analytical expression for the effective field-dependent quality factor $Q_J(H_a)$, finding that $Q_J(H_a) \propto \sqrt{J_c(H_a)}$. We suggest that measuring the field-dependence of $Q_J(H_a)$ would provide further evidence that this RCSJ model applies to a long $0$-$π$ junction between a d-wave and an s-wave superconductor.
