description: The gamma-ray burst (GRB) 070201 was a bright short-duration hard-spectrum GRB detected by the Inter-Planetary Network (IPN). Its error quadrilateral, which has an area of 0.124 sq. deg, intersects some prominent spiral arms of the nearby M31 (Andromeda) galaxy. Given the properties of this GRB, along with the fact that LIGO data argues against a compact binary merger origin in M31, this GRB is an excellent candidate for an extragalactic Soft Gamma-ray Repeater (SGR) giant flare, with energy of 1.4x10^45 erg. Analysis of ROTSE-IIIb visible light observations of M31, taken 10.6 hours after the burst and covering 42% of the GRB error region, did not reveal any optical transient down to a limiting magnitude of 17.1. We inspected archival and proprietary XMM-Newton X-ray observations of the intersection of the GRB error quadrilateral and M31, obtained about four weeks prior to the outburst, in order to look for periodic variable X-ray sources. No SGR or Anomalous X-ray Pulsar (AXP) candidates (periods in range 1 to 20 s) were detected. We discuss the possibility of detecting extragalactic SGRs/AXPs by identifying their periodic X-ray light curves. Our simulations suggest that the probability of detecting the periodic X-ray signal of one of the known Galactic SGRs/AXPs, if placed in M31, is about 10% (50%), using 50 ks (2 Ms) XMM-Newton exposures.

description: We theoretically investigate image propagation and storage in hot atomic vapor. A $4f$ system is adopted for imaging and an atomic vapor cell is placed over the transform plane. The Fraunhofer diffraction pattern of an object in the object plane can thus be transformed into atomic Raman coherence according to the idea of ``light storage''. We investigate how the stored diffraction pattern evolves under diffusion. Our result indicates, under appropriate conditions, that an image can be reconstructed with high fidelity. The main reason for this procedure to work is the fact that diffusion of opposite-phase components of the diffraction pattern interfere destructively.

description: The field of robotics has grown at an astonishing rate over the past two decades, and the interest in autonomous vehicles has grown even faster. Autonomous vehicles offer the unique promise of removing drivers from dangerous environments, and increasing the efficiency of our highways. However, the development of these systems is no trivial task. For an autonomous vehicle to effectively navigate and interact with the world, the vehicle must ( 1) determine where it is located and create an accurate assessment of its surroundings, (2) develop a feasible navigational path based on the current surroundings and the vehicle's destination, and (3) monitor the vehicle's progress as it moves through the environment. A deficiency in any of these requirements leads to results that are less desirable, and often dangerous.

This research presents a complete solution for designing and building an autonomous vehicle. It describes the overall concepts inherent in any autonomous system, and then illustrates how the theoretical concepts can be utilized in a real world application. This work was conducted parallel to the development of Old Dominion University's Autonomous Surface Vehicle, Lil' Blue. The research reviews the kinematic equations of motion needed to model the physical system, and introduces the Kalman filter which is used to assess the vehicle's state information. A vision processing algorithm lets the boat assess its surroundings, a navigational path planning algorithm determines the boat's target destination, and a unique PID controller eliminates the need for complex user commands to navigate towards the desired target point. The algorithms where physically tested throughout the ASV's development, and those results are presented in this work. The overall goal of this research is to outline the necessary components to develop an autonomous vehicle, and then demonstrate those precepts with a real world application. The result of this research is a fully functional ASV, which is well equipped to compete in the next AUVSI RoboBoat competition.

description: There is an increasing demand for domain-specific sofhuare. For example, the software to control a machine on a factory$oor is different in significant waysfrom the sojiware to manip- ulate large databases. The sojbvare engineer building real-time systems software to control a motor that powers a piece of machinery needs some understanding of the motor's servo system; whereas a sofrware engineer who designs the sofrware to manage large databases for the NASA Space Station needs specific knowledge about database models as well as the types of data han- dled on a long-term space vehicle. Specialization tracks within the Master of Sofrware Engineer- ing (MSE) Program at Carnegie Mellon University enable students to gain application domain knowledge while developing jimdamental sofrware engineering skills. The MSE Program cur- rently offers specialization tracks in real-time conpiting, human-computer interaction (HCI) and business. This paper overviews these tracks

description: The sample-to-sample fluctuations Delta F_N of the free energy in the Sherrington-Kirkpatrick model are shown rigorously to be related to bond chaos. Via this connection, the fluctuations become analytically accessible by replica methods. The replica calculation for bond chaos shows that the exponent mu governing the growth of the fluctuations with system size N, i.e. Delta F_N N^mu, is bounded by mu <= 1/4.

description: Precision infrared photometry from Spitzer has enabled the first direct studies of light from extrasolar planets, via observations at secondary eclipse in transiting systems. Current Spitzer results include the first longitudinal temperature map of an extrasolar planet, and the first spectra of their atmospheres. Spitzer has also measured a temperature and precise radius for the first transiting Neptune-sized exoplanet, and is beginning to make precise transit timing measurements to infer the existence of unseen low mass planets. The lack of stellar limb darkening in the infrared facilitates precise radius and transit timing measurements of transiting planets. Warm Spitzer will be capable of a precise radius measurement for Earth-sized planets transiting nearby M-dwarfs, thereby constraining their bulk composition. It will continue to measure thermal emission at secondary eclipse for transiting hot Jupiters, and be able to distinguish between planets having broad band emission versus absorption spectra. It will also be able to measure the orbital phase variation of thermal emission for close-in planets, even non-transiting planets, and these measurements will be of special interest for planets in eccentric orbits. Warm Spitzer will be a significant complement to Kepler, particularly as regards transit timing in the Kepler field. In addition to studying close-in planets, Warm Spitzer will have significant application in sensitive imaging searches for young planets at relatively large angular separations from their parent stars.

A Model for Star Formation, Gas Flows and Chemical Evolution in Galaxies at High Redshifts

Subjects: subject: Astrophysics (astro-ph)

description: Motivated by the increasing use of the Kennicutt-Schmidt (K-S) star formation law to interpret observations of high redshift galaxies, the importance of gas accretion to galaxy formation, and the recent observations of chemical abundances in galaxies at z~2-3, I use simple analytical models to assess the consistency of these processes of galaxy evolution with observations and with each other. I derive the time dependence of star formation implied by the K-S law, and show that the sustained high star formation rates observed in galaxies at z~2-3 require the accretion of additional gas. A model in which the gas accretion rate is approximately equal to the combined star formation and outflow rates broadly reproduces the observed trends of star formation rate with galaxy age. Using an analytical description of chemical evolution, I also show that this model, further constrained to have an outflow rate roughly equal to the star formation rate, reproduces the observed mass-metallicity relation at z~2.

description: Las plantaciones de castaño son una de las más rentables que se pueden realizar en las zonas de clima atlántico de Europa como muestra la existencia de una etiqueta de Denominación Geográfica Protegida en sus frutos. Hoy en día, un soto de castaños bien gestionado puede producir una ganancia de 10000 euros al año. Galicia tiene una gran historia de producción de castaña porque fue la principal fuente de carbohidratos hasta el siglo XIX, cuando la aparición de la enfermedad de la tinta destruyó aquellos sotos situados a altitudes por debajo de 600 m sobre el nivel del mar. El desarrollo de híbridos resistentes al castaño ha permitido el aumento de las plantaciones en Galicia en la última década. En la actualidad, coexisten en Galicia dos tipos diferentes de masas de castaño, unas asociadas a zonas de elevada altitud (ej. Ancares/Caurel) y otras a zonas de altitud más reducida (plantaciones nuevas). Las masas tradicionales de castaño están compuestas por árboles con edades superiores a los 500 años de aproximadamente 100 variedades diferentes que aseguran la producción de castaña y por lo tanto la resiliencia frente a eventos climáticos no predecibles (ej. viento, heladas..).

Investigating Stalling Events in Cerebral Blood Microcirculation and Implications for Cognitive Disease
Creators: name: Jamshidi, Mohammad
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The present doctoral thesis explores the sophisticated dynamics of cerebral blood flow and the related blood distribution factors in the context of brain microcirculation considering various physiological and pathological conditions applied in the brain microvasculature. The study focuses on the impact of the stalling events in the aged brain on blood pressure, hematocrit levels, transit time, and occlusions while considering the uneven distribution of the blood components at the bifurcation on the microcirculation structure. Additionally, the thesis aims to analyze the effects of the non-Newtonian viscosity on cerebral blood flow and apply the directed graph theory to reduce the computational cost of the mathematical model and make it plausible to use the computational fluid dynamics methods on the complex, realistic, dense, tortuous microvascular in the brain. The research employs advanced path analysis techniques to discover the shortest paths in different cerebral networks, examines the influence of the hematocrit variations on blood flow distribution at the upstream and the downstream regions, and identifies the change of the hematocrit level considering the depth of the network from the pial surface; furthermore, the research incorporates the brain vascular visualization as the post-processing step of the calculations, utilizing several open-source visualizing software to depict the blood flow patterns and the brain territories. Moreover, the tracer convection method is applied to enhance the understanding of the microcirculation level's transport phenomena. Finally, the research addresses the strategies in comprehensive data visualization related to the brain vessels, including the arteries, venous, and cortex. The study contributes to a better understanding and insight into cerebral blood flow dynamics and structure in the brain microvascular.
Effects of two-loop contributions in the pseudofermion functional renormalization group method for quantum spin systems

description: We implement an extension of the pseudofermion functional renormalization group (PFFRG) method for quantum spin systems that takes into account two-loop diagrammatic contributions. An efficient numerical treatment of the additional terms is achieved within a nested graph construction which recombines different one-loop interaction channels. In order to be fully self consistent with respect to self-energy corrections we also include certain three-loop terms of Katanin type. We first apply this formalism to the antiferromagnetic $J_1$-$J_2$ Heisenberg model on the square lattice and benchmark our results against the previous one-loop plus Katanin approach. Even though the RG equations undergo significant modifications when including the two-loop terms, the magnetic phase diagram -- comprising Néel ordered and collinear ordered phases separated by a magnetically disordered regime -- remains remarkably unchanged. Only the boundary position between the disordered and the collinear phases is found to be moderately affected by two-loop terms. On the other hand, critical RG scales, which we associate with critical temperatures $T_\text{c}$, are reduced by a factor of $\sim2$ indicating that the two-loop diagrams play a significant role in enforcing the Mermin-Wagner theorem. Improved estimates for critical temperatures are also obtained for the Heisenberg ferromagnet on the 3D simple cubic lattice where errors in $T_\text{c}$ are reduced by $\sim34\%$.

description: We study the stability properties of the twisted vortex solutions in the semilocal Abelian Higgs model with a global $\mathbf{SU}(2)$ invariance. This model can be viewed as the Weinberg-Salam theory in the limit where the non-Abelian gauge field decouples, or as a two component Ginzburg-Landau theory. The twisted vortices are characterized by a constant global current ${\cal I}$, and for ${\cal I}\to 0$ they reduce to the semilocal strings, that is to the Abrikosov-Nielsen-Olesen vortices embedded into the semilocal model. Solutions with ${\cal I}\neq 0$ are more complex and, in particular, they are {\it less energetic} than the semilocal strings, which makes one hope that they could have better stability properties. We consider the generic field fluctuations around the twisted vortex within the linear perturbation theory and apply the Jacobi criterion to test the existence of the negative modes in the spectrum of the fluctuation operator. We find that twisted vortices do not have the homogeneous instability known for the semilocal strings, neither do they have inhomogeneous instabilities whose wavelength is less than a certain critical value. This implies that short enough vortex pieces are perturbatively stable and suggests that small vortex loops could perhaps be stable as well. For longer wavelength perturbations there is exactly one negative mode in the spectrum whose growth entails a segmentation of the uniform vortex into a non-uniform, `sausage like' structure. This instability is qualitatively similar to the hydrodynamical Plateau-Rayleigh instability of a water jet or to the Gregory-Laflamme instability of black strings in the theory of gravity in higher dimensions.

description: Electric current and spacial displacement due to trembling motion [Zitterbewegung (ZB)] of electrons in graphene in the presence of an external magnetic field are described. Contributions of both inequivalent $K$ points in the Brillouin zone of graphene are considered. It is shown that, when the electrons are prepared in the form of wave packets, the presence of a quantizing magnetic field $B$ has very important effects on ZB. (1) For $B\neq 0$ the ZB oscillations are permanent, for B=0 they are transient. (2) For $B\neq 0$ many ZB frequencies appear, for B=0 only one frequency is at work. (3) For $B\neq 0$ both interband and intraband (cyclotron) frequencies contribute to ZB, for B=0 there are no intraband frequencies. (4) Magnetic field intensity changes not only the ZB frequencies but the entire character of ZB spectrum. An emission of electromagnetic dipole radiation by the trembling electrons is proposed and described. It is argued that graphene in a magnetic field is a promising system for an experimental observation of Zitterbewegung.

Difference topology is a novel technique used to unveil the structure of stable protein-DNA complexes involving two or more DNA segments. We analyze such experiments for the Mu protein-DNA complex. We characterize the solutions to the corresponding tangle equations by certain knotted graphs. By investigating planarity conditions on these graphs we show that there is a unique biologically relevant solution. That is, we show there is a unique rational tangle solution, which is also the unique solution with small crossing number.

description: Chestnut plantations are one of the most profitable trees that can be used in the Atlantic area of Europe as shown the existence of a DOP label that Galicia chestnut fruit has. Nowadays, a well managed chestnut fruit plantation can deliver 10000 euros per year. Galicia has a long history of chestnut production because it was the main source of carbohydrates until the XIX century, when the ink illnesses destroyed those chestnut plantations placed below 600 m above sea level. The development of ink-resistant chestnut hybrids have allowed an increase of the plantations in Galicia in the last decade. So, there are two different types of chestnut stands co-existing nowadays in Galicia, those in high altitude areas (i.e. Ancares/Caurel) and those associated to low altitude areas (new plantations). Traditional Chestnut stands are composed of over 500 years-old trees from around 100 different varieties that ensures chestnut production and therefore resilience to unpredictable weather events (i.e. winds, frosts..).

description: We propose a simple model to analyze the traffic of droplets in microfluidic ``dual networks''. Such functional networks which consist of two types of channels, namely those accessible or forbidden to droplets, often display a complex behavior characteristic of dynamical systems. By focusing on three recently proposed configurations, we offer an explanation for their remarkable behavior. Additionally, the model allows us to predict the behavior in different parameter regimes. A verification will clarify fundamental issues, such as the network symmetry, the role of the driving conditions, and of the occurrence of reversible behavior. The model lends itself to a fast numerical implementation, thus can help designing devices, identifying parameter windows where the behavior is sufficiently robust for a devices to be practically useful, and exploring new functionalities.

description: Cosmological relaxation of the electroweak scale is improved by using particle production to trap the relaxion. We combine leptogenesis with such a relaxion model that has no extremely small parameters or large e-foldings. Scanning happens after inflation--now allowed to be at a high scale--over a sub-Planckian relaxion field range for an $\mathcal{O}(100)$ TeV cut-off scale of new physics. Particle production by the relaxion also reheats the universe and generates the baryonic matter-antimatter asymmetry. We propose a realisation in which out-of-equilibrium leptons, produced by the relaxion, scatter with the thermal bath through interactions that violate CP and lepton number via higher-dimensional operators. Such a minimal effective field theory setup, with no new physics below the cut-off, naturally decouples new physics while linking leptogenesis to relaxion particle production; the baryon asymmetry of the universe can thus be intrinsically tied to a weak scale hierarchy.

Recent $\boldsymbol{B}$ Physics Anomalies - a First Hint for Compositeness?

Publisher: name: arXiv
Year: 2017
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We scrutinize the recently further strengthened hints for new physics in semileptonic $B$-meson decays, focusing on the 'clean' ratios of branching fractions $R_K$ and $R_{K^\ast}$ and examining to which pattern of new effects they point to. We explore in particular the hardly considered, yet fully viable, option of new physics in the right-handed electron sector and demonstrate how a recently proposed framework of leptons in composite Higgs setups naturally solves both the $R_K$ and $R_{K^\ast}$ anomalies via a peculiar structure of new physics effects, predicted by minimality of the model and the scale of neutrino masses. Finally, we also take into account further observables, such as ${\cal B}(B_s \to μ^+μ^-)$, $ΔM_{B_s}$, and angular observables in $B \to K^{\ast} μ^+ μ^-$ decays, to arrive at a comprehensive picture of the model concerning (semileptonic) $B$ decays. We conclude that -- since it is in good agreement with the experimental situation in flavor physics and also allows to avoid ultra-light top partners -- the model furnishes a very promising scenarios of Higgs compositeness in the light of LHC data.

description: The discovery of dark energy (DE) as the physical cause for the accelerated expansion of the Universe is the most remarkable experimental finding of modern cosmology. However, it leads to insurmountable theoretical difficulties from the point of view of fundamental physics. Inflation, on the other hand, constitutes another crucial ingredient, which seems necessary to solve other cosmological conundrums and provides the primeval quantum seeds for structure formation. One may wonder if there is any deep relationship between these two paradigms. In this work, we suggest that the existence of the DE in the present Universe could be linked to the quantum field theoretical mechanism that may have triggered primordial inflation in the early Universe. This mechanism, based on quantum conformal symmetry, induces a logarithmic, asymptotically-free, running of the gravitational coupling. If this evolution persists in the present Universe, and if matter is conserved, the general covariance of Einstein's equations demands the existence of dynamical DE in the form of a running cosmological term whose variation follows a power law of the redshift.

The Stevens Award was created to recognize outstanding contributions to the literature or practice of methods for software and systems development.

description: We have presented the results of our next-to-next-to-leading order (NNLO) QCD analysis of nuclear parton distribution functions (nuclear PDFs) [Phys. Rev. D 93 (2016) 014026, arXiv:1601.00939 [hep-ph]] using all available neutral current charged-lepton ($\ell ^\pm$ + nucleus) deeply inelastic scattering (DIS) data as well as Drell-Yan (DY) cross-section ratios $σ_{\rm DY}^{A}/σ_{\rm DY}^{A^\prime}$ for a variety of nuclear targets. We have studied in detail the parametrizations and the atomic mass (A) dependence of the nuclear PDFs at NNLO at the input scale, $Q_0^2 = 2 \, {\rm GeV^2}$. Our {\tt KA15} nuclear PDFs provides a complete set of nuclear PDFs, $f_i^{(A, Z)}(x, Q^2)$, with a full functional dependence on $x$, A, $Q^2$. The uncertainties of the obtained nuclear modification factors for each parton flavour as well as the corresponding observables are estimated using the well-known Hessian method. The nuclear heavy quark contributions are also included into the analysis in the framework of zero-mass variable flavour number scheme (ZM-VFNS). We compare the results of our parametrization with all available nuclear DIS data and the results of other nuclear PDFs groups. We have found that our nuclear PDFs to be in reasonably good agreement with results in the literature. The estimates of errors provided by our global analysis ({\tt KA15}) are rather smaller than those of other groups. We have briefly reviewed different aspects of recent LHC heavy-ion collisions data including the first experimental data from the LHC proton+lead ($p-pb$) and lead+lead ($pb-pb$) run which can be used in the global fits of nuclear PDFs.

description: We investigate the relations among the stellar continuum-subtracted 8 μm polycyclic aromatic hydrocarbon (PAH 8 μ m) emission, 24 μm hot dust emission and 160 μm cold dust emission in 15 nearby face-on spiral galaxies in the Spitzer Infrared Nearby Galaxies Survey sample. The relation between PAH 8 and 24 μm emission measured in ∼2 kpc regions is found to exhibit a significant amount of scatter, and strong spatial variations are observed in the (PAH 8 μ m)/24 μm surface brightness ratio. In particular, the (PAH 8 μ m)/24 μm surface brightness ratio is observed to be high in the diffuse interstellar medium and low in bright star-forming regions and other locations with high 24 μm surface brightness. PAH 8 μ m emission is found to be well-correlated with 160 μm emission on spatial scales of ∼2 kpc, and the (PAH 8 μ m)/160 μm surface brightness ratio is generally observed to increase as the 160 μm surface brightness increases. These results suggest that the PAHs are associated with the diffuse, cold dust that produces most of the 160 μm emission in these galaxies, and the variations in the (PAH 8 μ m)/160 μm ratio may generally be indicative of either the intensity or the spectrum of the interstellar radiation field that is heating both the PAHs and the diffuse interstellar dust.

Possible Chiral Topological Superconductivity in CrO$_{2}$ bilayers

description: We address the possible emergence of spin triplet superconductivity in CrO$_{2}$ bilayers, which are half-metals with fully spin-polarized conducting bands. Starting from a lattice model, we show that chiral $p+ip$ states compete with non-chiral $p$-wave ones. At large doping, the $p+ip$ channel has a sequence of topological phase transitions that can be tuned by gating effects and interaction strength. Among several phases, we find chiral topological phases having a single Majorana mode at the edge. We show that different topological superconducting phases could spontaneously emerge in the vicinity of the van-Hove singularities of the band.

Tunable-slip boundaries for coarse-grained simulations of fluid flow

description: On the micro- and nanoscale, classical hydrodynamic boundary conditions such as the no-slip condition no longer apply. Instead, the flow profiles exhibit ``slip`` at the surface, which is characterized by a finite slip length (partial slip). We present a new, systematic way of implementing partial-slip boundary conditions with arbitrary slip length in coarse-grained computer simulations. The main idea is to represent the complex microscopic interface structure by a spatially varying effective viscous force. An analytical equation for the resulting slip length can be derived for planar and for curved surfaces. The comparison with computer simulations of a DPD (dissipative particle dynamics) fluid shows that this expression is valid from full-slip to no-slip.

Unsigned state models for the Jones polynomial

description: It is well a known and fundamental result that the Jones polynomial can be expressed as Potts and vertex partition functions of signed plane graphs. Here we consider constructions of the Jones polynomial as state models of unsigned graphs and show that the Jones polynomial of any link can be expressed as a vertex model of an unsigned embedded graph. In the process of deriving this result, we show that for every diagram of a link in the 3-sphere there exists a diagram of an alternating link in a thickened surface (and an alternating virtual link) with the same Kauffman bracket. We also recover two recent results in the literature relating the Jones and Bollobas-Riordan polynomials and show they arise from two different interpretations of the same embedded graph.

The Impact of Partisan Identity on Voter Support after Candidate Transgression
Creators: name: Howard, Kathryn Anne
Publisher: name: University of Illinois at Chicago

description: It is not rare for US politicians to commit multiple moral transgressions in office, yet also to maintain the support of their voters. This may occur because voters experience their political party as a social identity, and thus feel motivated to support their party regardless of a candidate’s actions. Three studies explore this possibility at three different levels of cognitive processing. In Study 1, participants (n = 215) rated 200 behaviors as transgressive or non-transgressive as quickly as possible. When “thinking fast” about behavior, strong partisans were more likely to categorize ingroup behaviors as transgressive than outgroup behaviors, and made categorizations more quickly. High-identifiers may experience a disgust or startle response when first learning of transgression, thus quickening RT and increasing the likelihood behavior is categorized as transgressive. In Study 2, participants (n = 731) rated political ingroup, outgroup, or job candidate (control) transgressive behaviors. When given time to deliberate about behaviors, the opposite effect from Study 1 emerged: Participants who were strongly identified with their political party were more likely to rate ingroup behaviors as less wrong and more excusable than the same behaviors committed by outgroup or control candidates, providing evidence of ingroup biased motivated reasoning. Study 3 investigated the extent of transgression severity voters are willing to endure from ingroup candidates before abandoning a favored candidate. Across 70 trials, participants (n = 493) chose to vote for an ingroup candidate or outgroup candidate after learning the ingroup candidate transgressed. Statistical modeling revealed that people were more likely to abandon ingroup candidates as transgression severity increased, and that participants with a stronger ideological identity were more likely to vote for transgressive ingroup candidates than less-identified individuals. Furthermore, Republicans possessed a higher severity threshold than Democrats, such that they voted for the ingroup candidate for more severe transgressions than Democrats.
Off-diagonal Ground State Properties of a 1D Gas of Fermi Hard Rods

description: A variational Monte Carlo calculation of the one-body density matrix and momentum distribution of a system of Fermi hard rods (HR) is presented and compared with the same quantities for its bosonic counterpart. The calculation is exact within statistical errors since we sample the exact ground state wave function, whose analytical expression is known. The numerical results are in good agreement with known asymptotic expansions valid for Luttinger liquids. We find that the difference between the absolute value of the bosonic and fermionic density matrices becomes marginally small as the density increases. In this same regime, the corresponding momentum distributions merge into a common profile that is independent of the statistics. Non-analytical contributions to the one--body density matrix are also discussed and found to be less relevant with increasing density.
