Charged Pion Production in 2 to 8 AGeV Central Au+Au Collisions
Creators: name: Klay, J. L.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Momentum spectra of charged pions over nearly full rapidity coverage from target to beam rapidity have been measured in the 0-5% most central Au+Au collisions in the beam energy range from 2 to 8 AGeV by the E895 Experiment. Using a thermal parameterization to fit the transverse mass spectra, rapidity density distributions are extracted. The observed spectra are compared with predictions from the RQMD v2.3 cascade model and also to a thermal model including longitudinal flow. The total 4$π$ yields of the charged pions are used to infer an initial state entropy produced in the collisions.

description: An accurate simulation of the excited states of molecules can enable the study of many important processes that are fundamental to nature and the life forms we know, but these calculations are seriously limited by the high complexity and computational efforts involved. In this talk, I will discuss how machine learning algorithms can enable an efficient and accurate computation of photo-initiated reactions of molecules - from light excitation to nonradiative decay [1]. On the example of the methylenimmonium cation, I will introduce the SchNarc approach [2] and demonstrate the accuracy of its machine-learned potentials via UV/visible absorption spectra and nonadiabatic dynamics simulations [2,3]. Better statistics and long time-scale dynamics simulations become accessible with SchNarc, which would not be feasible without the help of ML [2-4].

description: The equivalence of principal bundles with transitive Lie groupoids due to Ehresmann is a well known result. A remarkable generalisation of this equivalence, due to Mackenzie, is the equivalence of principal bundle extensions with those transitive Lie groupoids over the total space of a principal bundle, which also admit an action of the structure group by automorphisms. This paper proves the existence of suitably equivariant transition functions for such groupoids, generalising consequently the classification of principal bundles by means of their transition functions, to extensions of principal bundles by an equivariant form of Čech cohomology.

description: To examine prevalence trends in the use of smoked tobacco products in 11 South American (SA) countries (i.e., Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, Suriname, Uruguay, and Venezuela) and their association with country-specific socio-demographic index (SDI) over 30 years. The estimates of SDI and smoked tobacco prevalence stratified by age, sex, and country were extracted from the Global Burden of Disease Study (1990–2019) on individuals aged 15+. The annual percentage changes (APCs) of trends in country-specific prevalence of smoked tobacco were evaluated using Joinpoint regression. Correlation analysis was also used to explore the association between country-specific prevalence of smoked tobacco and their SDIs, a measure of developmental status considering income per capita, educational attainment, and total fertility rate. While all SA countries showed an overall decline in smoked tobacco use prevalence between 1990 and 2019 (APCs between −0.52%-and −4.73%; p < 0.05), Bolivia and Ecuador showed a significant increasing trend (APCs of 0.34% and 0.20%). Country-specific SDI was strongly and significantly correlated (rs = −0.99 to −0.85) with smoking prevalence in SA countries, except for Ecuador and Bolivia (rs = 0.16 and 0.36, respectively). In recent decades, most SA countries have experienced a significant reduction in the prevalence of smoked tobacco use, except Ecuador and Bolivia, where smoking rates have risen, showing a direct correlation with SDI. These findings can contribute to the design and implementation of strategies and policies for tobacco prevention and control in the SA region especially within the two affected countries – Ecuador and Bolivia.

description: Given a flat-foldable origami crease pattern $G=(V,E)$ (a straight-line drawing of a planar graph on a region of the plane) with a mountain-valley (MV) assignment $μ:E\to\{-1,1\}$ indicating which creases in $E$ bend convexly (mountain) or concavely (valley), we may \emph{flip} a face $F$ of $G$ to create a new MV assignment $μ_F$ which equals $μ$ except for all creases $e$ bordering $F$, where we have $μ_F(e)=-μ(e)$. In this paper we explore the configuration space of face flips for a variety of crease patterns $G$ that are tilings of the plane, proving examples where $μ_F$ results in a MV assignment that is either never, sometimes, or always flat-foldable for various choices of $F$. We also consider the problem of finding, given two foldable MV assignments $μ_1$ and $μ_2$ of a given crease pattern $G$, a minimal sequence of face flips to turn $μ_1$ into $μ_2$. We find polynomial-time algorithms for this in the cases where $G$ is either a square grid or the Miura-ori, and show that this problem is NP-hard in the case where $G$ is the triangle lattice.

description: Mid-rapidity $K^{*0}(892)\to Kπ$ and $K^{*\pm}(892)\to K_S^0π^{\pm}$ are measured in Au+Au and pp collisions at $\sqrt{s_{NN}}$=200GeV using the STAR detector at RHIC. The $K^{*0}(892)$ mass is systematically shifted at small transverse momentum for both Au+Au and pp collisions. The $K^{*0}(892)$ transverse mass spectra are measured in Au+Au collisions at different centralities and in pp collisions. The $K^{*0}(892)$ mean transverse momentum as a function of the collision centrality is compared to those of identified $π^{-}$, $K^{-}$ and $\bar{p}$. The $K^{*}/K$ and $ϕ/K^{*}$ ratios are compared to measurements in A+A, $pp$, $\bar{p}p$, $e^{+}e^{-}$ collisions at various colliding energies. The physics implications of these measurements are also discussed.

description: Entanglement between a quantum system and its environment leads to loss of coherence in the former. In general, the temporal fate of coherences is complicated. Here, we establish the connection between decoherence of a central system and fidelity decay in the environment for a variety of situations, including both, energy conserving and dissipative couplings. We show how properties of unitary time evolution of the environment can be inferred from the non-unitary evolution of coherences in the central system. This opens up promising ways for measuring Loschmidt echoes in a variety of situations.

description: We study scenarios where loop processes give the dominant contributions to dark matter decay or annihilation despite the presence of tree level channels. We illustrate this possibility in a specific model where dark matter is part of a hidden sector that communicates with the Standard Model sector via a heavy neutrino portal. We explain the underpinning rationale for how loop processes mediated by the portal neutrinos can parametrically dominate over tree level decay channels, and demonstrate that this qualitatively changes the indirect detection signals in positrons, neutrinos, and gamma rays.

description: Recognizing the severe consequences of alcohol consumption during pregnancy, such as fetal alcohol spectrum disorders (FASDs), the present study explored the role of drinking attitudes, trait impulsivity, and decision-making toward instant gratification in alcohol craving and consumption during pregnancy among mothers of reproductive age. Utilizing participants from Amazon Mechanical Turk (N = 141), we first categorized mothers into three groups: those who neither craved nor consumed alcohol during their last pregnancy, those who craved but did not consume, and those who craved and consumed alcohol. Using binomial logistic regression, we then examined what factors, if any, could differentiate between (a) mothers who craved alcohol during pregnancy and those who did not and (b) mothers who resisted alcohol cravings and those who yielded to them. The findings indicated that drinking attitudes significantly predicted alcohol craving during pregnancy. However, trait impulsivity emerged as a significant predictor of alcohol consumption among those who experienced cravings. The present study contributes to a better understanding of psychological mechanisms underlying alcohol craving and consumption during pregnancy, which in turn may contribute to the development of targeted interventions for this problem.

Galaxies Inside Stromgren Spheres of Luminous Quasars at z>6: Detection of The First Galaxies
Creators: name: Cen, Renyue
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The intrinsic Lyman-alpha emission lines of normal galaxies before reionization are much absorbed by the damping wing of the Gunn-Peterson trough, rendering their direct detection nearly impossible, if their intrinsic line widths are less than ~100km/s. High redshift luminous quasars prior to the completion of cosmological reionization at z~6, on the other hand, are capable of producing large HII regions around them (Stromgren spheres) to allow their intrinsic Lyman-alpha emission lines to be transmitted without overwhelming absorption (Cen & Haiman 2000). We suggest that targeted observations at the Stromgren spheres of known luminous quasars at z >= 6 would be able to detect Lyman-alpha emission lines of galaxies inside the Stromgren spheres largely unattenuated. A tunable, very narrowband filter of Δλ\over λ~ 0.1% or a narrowband filter of Δλ\over λ~1% with follow-up spectroscopic identifications will be required. Such observations could directly observe the sources of cosmological reionization including possibly the Pop III galaxies at z=6-20 by JWST. Possible applications include determinations of the ionization state of the intergalactic medium, the sizes of the Stromgren spheres, the ages of the quasars, the luminosity function of high redshift galaxies and its evolution, the spatial distribution of galaxies and its evolution, the biased distribution of galaxies around quasars and the anisotropy of quasar emission. Observations using Keck-class telescopes may already be made to enable a differentiation between a fully neutral and a 10% neutral intergalactic medium at z>6.

description: Partial voluming (PV) is arguably the last crucial unsolved problem in Bayesian segmentation of brain MRI with probabilistic atlases. PV occurs when voxels contain multiple tissue classes, giving rise to image intensities that may not be representative of any one of the underlying classes. PV is particularly problematic for segmentation when there is a large resolution gap between the atlas and the test scan, e.g., when segmenting clinical scans with thick slices, or when using a high-resolution atlas. In this work, we present PV-SynthSeg, a convolutional neural network (CNN) that tackles this problem by directly learning a mapping between (possibly multi-modal) low resolution (LR) scans and underlying high resolution (HR) segmentations. PV-SynthSeg simulates LR images from HR label maps with a generative model of PV, and can be trained to segment scans of any desired target contrast and resolution, even for previously unseen modalities where neither images nor segmentations are available at training. PV-SynthSeg does not require any preprocessing, and runs in seconds. We demonstrate the accuracy and flexibility of the method with extensive experiments on three datasets and 2,680 scans. The code is available at https://github.com/BBillot/SynthSeg.

description: Background: Multiracial American adults have the highest rates of binge drinking and illicit drug use of all racial groups, yet little is known about the risk and promotive factors that contribute to their substance use. Objectives: This study examines how individual factors (i.e., shifting racial expressions, perceived racial ambiguity, creating third space, self-esteem, depression) and family cohesion relate to substance use among 574 Multiracial young adults in the United States (Mage = 19.87). Results: Findings suggested that Multiracial young adults who reported higher scores on perceived racial ambiguity, self-esteem, and depression had a higher likelihood of drinking to feel drunk and binge drinking, while more family cohesion with their first primary caregiver was associated with a lower likelihood of drinking to feel drunk. Perceived racial ambiguity was also associated with a higher likelihood of illicit drug use, while family cohesion with their second primary caregiver was associated with a lower likelihood of illicit drug use. Multiracial young adults with White ancestry were more likely to drink to feel drunk than Multiple Minority Multiracials, but there were no differences between groups in binge drinking or illicit drug use. Conclusions: In sum, the unique racialized experiences, mental health, and family relationships of Multiracial Americans may play a role in substance use.

description: The presence of a kHz frequency in LMXBs has been expected from scaling laws, by analogy with the QPO phenomenon in HMXB X-ray pulsars. Interpretation of the two kHz frequencies, observed in accreting neutron stars, in terms of non-linear resonance in strong-field gravity led to the prediction of twin QPOs in black hole systems, in a definite frequency ratio (such as 2/3). The imprint of a subharmonic of the 401 Hz rotation rate in the frequencies of the QPOs detected in the accreting millisecond pulsar is at once a signature of non-linear resonance and of coupling between accretion disk modes and the neutron star spin.

description: Sleep disturbances (SDs) in childhood can negatively impact behavioral and emotional control, which can lead to an increase in risky behaviors, such as substance use, including alcohol. Data from 2,132 subjects who participated in the French TEMPO cohort from 1991 to 2018 were used. Sleep disturbances observed from ages 3 to 16 years defined our exposure. Alcohol use in adulthood was measured by alcohol consumption trajectories ascertained by using Group-Based Trajectory Modeling (GBTM) and constitutes our outcomes. The association between sleep disturbances in childhood and alcohol consumption trajectories was studied using multinomial logistic regression. Sleep disturbances at ≤ 16 years were observed in 26.7% of participants. Three alcohol use trajectories were defined: “light-drinkers”, “moderate-drinkers”, and “heavy-drinkers”. Accounting for many confounders, we found statistically significant associations between sleep disturbances and alcohol use trajectories. Using “light-drinkers” trajectory as reference, we found that compared to children with no sleep disturbances, those with sleep disturbances had a higher likelihood to be in the “moderate-drinkers” (ORa = 1.51; 95% CI = 1.09–2.10) and “heavy-drinkers” trajectory (ORa = 2.34; 95% CI = 1.27–4.34). This study suggests that sleep disturbances in childhood are associated with an increased risk of higher alcohol consumption in adulthood and highlights the importance of healthy sleep, particularly in children and adolescents, to prevent the onset of certain risky behaviors.
Rheonomic systems with nonlinear nonholonomic constraints: the Voronec equations

description: One of the earliest formulations of dynamics of nonholonomic systems traces back to 1895 and it is due to Caplygin, who developed his analysis under the assumption that a certain number of the generalized coordinates do not occur neither in the kinematic constraints nor in the Lagrange function. A few years later Voronec derived the equations of motion for nonholonomic systems removing the restrictions demanded by the Caplygin systems. Although the methods encountered in the following years favour the use of the quasi-coordinates, we will pursue the Voronec method which deals with the generalized coordinates directly. The aim is to establish a procedure for extending the equations of motion to nonlinear nonholonomic systems, even in the rheonomic case.

description: We study the dependence on the number of colors of the leading pi pi scattering amplitude in chiral dynamics. We demonstrate the existence of a critical number of colors for and above which the low energy pi pi scattering amplitude computed from the simple sum of the current algebra and vector meson terms is crossing symmetric and unitary at leading order in a truncated and regularized 1/Nc expansion. The critical number of colors turns out to be Nc=6 and is insensitive to the explicit breaking of chiral symmetry. Below this critical value, an additional state is needed to enforce the unitarity bound; it is a broad one, most likely of "four quark" nature.

description: We study the structure of generalized parton distributions in impact parameter space with the aim of determining the size and role of small transverse separations components in the quarks wave function. We analyze the relation between transverse momentum components and transverse separations. Wave functions with large transverse momentum components can simultaneously reproduce the behavior of the Dirac form factor at large momentum transfer, and of the deep inelastic structure functions at Bjorken x -> 1. The presence of large momentum components does not ensure, however, the dominance of small transverse distances at large x. We suggest that experiments measuring the attenuation of hadrons in the nuclear medium, or the onset of color transparency, can provide an alternative source of information on generalized parton distributions, by mapping out the behavior of the transverse components of the wave function.

description: We compare the first direct angular diameter measurements obtained on our closest stellar neighbour, Alpha Centauri, to recent model diameters constrained by asteroseismic observations. Using the VINCI instrument installed at ESO's VLT Interferometer (VLTI), the angular diameters of the two main components of the system, Alpha Cen A and B, were measured with a relative precision of 0.2% and 0.6%, respectively. Particular care has been taken in the calibration of these measurements, considering that VINCI is estimating the fringe visibility using a broadband K filter. We obtain uniform disk angular diameters for Alpha Cen A and B of UD[A] = 8.314 +/- 0.016 mas and UD[B] = 5.856 +/- 0.027 mas, and limb darkened angular diameters of LD[A] = 8.511 +/- 0.020 mas and LD[B] = 6.001 +/- 0.034 mas. Combining these values with the parallax from Soderhjelm (1999), we derive linear diameters of D[A] = 1.224 +/- 0.003 Dsun and D[B] = 0.863 +/- 0.005 Dsun. These values are compatible with the masses published by Thevenin et al.(2002) for both stars.

description: Large-scale data-mining workflows are increasingly able to predict successfully new chemicals that possess a targeted functionality. The success of such materials discovery approaches is nonetheless contingent upon having the right data source to mine, adequate supercomputing facilities and machine-learning workflows to calculate or sample a large range of materials, and algorithms that suitably encode structure-function relationships as datamining workflows which progressively short list data toward the prediction of a lead material for experimental validation. This talk shows how to meet these data-science requirements via 'chemistry-aware' natural language processing, image recognition and machine learning developments using case studies to showcase their successful application to data-driven materials discovery.

description: The coalescence model based on nucleon distribution functions from an isospin-dependent transport model is used to study the production of light clusters such as deuteron, triton, and $^{3}$He from heavy-ion collisions induced by neutron-rich nuclei at intermediate energies. It is found that the emission time of light clusters depends on their masses. For clusters with the same momentum per nucleon, heavier ones are emitted earlier. Both the yield and energy spectrum of light clusters are sensitive to the density dependence of nuclear symmetry energy, with more light clusters produced in the case of a stiff symmetry energy. On the other hand, effects due to the stiffness of the isoscalar part of nuclear equation of state and the medium dependence of nucleon-nucleon cross sections on light cluster production are unimportant. We have also studied the correlation functions of clusters, and they are affected by the density dependence of nuclear symmetry energy as well, with the stiff symmetry energy giving a stronger anti-correlation of light clusters, particularly for those with large kinetic energies. Dependence of light cluster production on the centrality and incident energy of heavy ion collisions as well as the mass of the reaction system is also investigated.

description: Advanced data analysis methodologies, and in particular dimensionality reduction techniques, are now used more and more widely in the single-molecule charge transport community. They allow for comprehensive exploration of large datasets, where data display significant variance and sometimes contain (unknown) sub-populations. To this end, unsupervised approaches, which do not rely on class labels or pre-defined expectations can be advantageous. Multi-Parameter Vector Classification (MPVC) is one example and PCA-based methods have also been employed in this context [1,2,3]. We have recently shown how Transfer Learning may be employed to identify and quantify hidden features in single-molecule charge transport data [3]. Using open-access neural networks such as AlexNet, trained on millions of seemingly unrelated image data, feature recognition then does not require network training with application-specific data. Instead, the network recognises features in the input that it had learned in other contexts and, for example, identifies different shapes in conductance-distance traces as images of different worm species. Thus, our results show how Deep Learning methodologies can readily be employed for unsupervised data classification, even if the amount of problem-specific, âownâ data is limited.

description: It is pointed out that the diagonal amplitude of the $E1-E1$ chromo-electric interaction with soft gluon fields (chromo-polarizability) can be measured directly for the $J/ψ$ and $Υ$ resonances in the decays $J/ψ\to ππ\ell^+ \ell^-$ and $Υ\to ππ\ell^+ \ell^-$ with soft pions. For the $J/ψ$ this amplitude is often discussed in connection with the $J/ψ$ interaction with nuclear matter, while for the $Υ$ the chromo-polarizability enters the estimates of the non-perturbative mass shift of the resonance relevant to precision determination of the $b$ quark mass from the $Υ$ mass.

description: Οι κοινωνικές, οι πολιτικές και οι οικονομικές συνθήκες, αλλά και η άνοδος της μετανάστευσης προς εύρεση καλύτερων συνθηκών διαβίωσης, έχουν οδηγήσει στην ανάγκη στέγασης ενός μεγάλου αριθμού ανθρώπων στα σύγχρονα αστικά κέντρα. Για τη στέγαση αυτού του πληθυσμού απαιτείται η δημιουργία συγκροτημάτων κατοίκησης, τα οποία θα συμβάλουν και στην κοινωνική, ψυχολογική και επαγγελματική επανένταξη τους μέσω της δομής και των λειτουργιών τους. Δύο παραδείγματα που έχουν επιτύχει σε μεγάλο βαθμό τα παραπάνω είναι το πρόγραμμα Housing First στη Φινλανδία και οι επεκτάσιμες κατοικίες του αρχιτεκτονικού γραφείου ELEMENTAL στη Χιλή και το Μεξικό.
Με βάση τον παραπάνω προβληματισμό και τα δύο παραδείγματα, στόχος της παρούσας διπλωματικής εργασίας είναι ο σχεδιασμός ενός αυτοδιαχειριζόμενου συγκροτήματος συλλογικής κατοίκησης που αποτελείται από επεκτάσιμες μονάδες κατοικίας, το οποίο θα μεταβάλλεται στο χρόνο ανάλογα με τις ανάγκες, τις επιθυμίες και την αισθητική των κατοίκων του. Προκειμένου το συγκρότημα να εντάσσεται στον Αθηναϊκό αστικό ιστό, η μορφολογία του, βασίστηκε σε αυτήν της σύγχρονης ελληνικής πολυκατοικίας και για το λόγο αυτό ο σχεδιασμός του ακολουθεί ως έναν μεγάλο βαθμό τις διατάξεις του νέου οικοδομικού κανονισμού.

A systematically study of thermal width of heavy quarkonia in a finite temperature magnetized background from holography

description: By simulating the finite temperatures magnetized background in the RHIC and LHC energies, we systematically study the characteristics of thermal widths and potentials of heavy quarkonia. It is found that the magnetic field has less influence on the real potential, but has a significant influence on the imaginary potential, especially in the low deconfined temperature. Extracted from the effect of thermal worldsheet fluctuations about the classical configuration, the thermal width of $Υ(1s)$ in the finite temperature magnetized background is investigated. It is found that at the low deconfined temperature the magnetic field can generate a significant thermal fluctuation of the thermal width of $Υ(1s)$, but with the increase of temperature, the effect of magnetic field on the thermal width becomes less important, which means the effect of high temperature completely exceeds that of magnetic field and magnetic field become less important at high temperature. The thermal width decreases with the increasing rapidity at the finite temperature magnetized background. It is also observed that the effect of the magnetic field on the thermal width when dipole moving parallel to the magnetic field direction are larger than that moving perpendicular to the magnetic field direction, which implies that the magnetic field tends to enhance thermal fluctuation when dipole moving parallel to the direction of magnetic field. The thermal width of $Υ(1S)$ hardly changes with the increasing temperature when dipole moving perpendicular to the magnetic field. But when dipole moving parallel to the magnetic field, the thermal width at low temperature is obviously larger than that at high temperature.

description: We present and investigate a new class of quantum channels, what we call `universal collective rotation channels', that includes the well-known class of collective rotation channels as a special case. The fixed point set and noise commutant coincide for a channel in this class. Computing the precise structure of this C*-algebra is a core problem in a particular noiseless subsystem method of quantum error correction. We prove that there is an abundance of noiseless subsystems for every channel in this class and that Young tableaux combinatorics can be used to explicitly compute these subsystems.

description: Why would weaker allies refuse to comply with the great power’s demands even when the latter threatens punishment? The alliance scholarship tells us that the great power's failure to persuade is usually due to a threat that lacks credibility. However, some threats are seen as credible. Thus, the puzzle: why do weaker allies sometimes not comply even when they perceive the great power as capable and likely to impose severe punishment? This dissertation uses historical case studies and process tracing to examine how allied governments conceptualize the consequences of responding to a great power’s pressure for compliance.
This dissertation identifies "saliency of issue" and "saliency of timeframe" as each relevant factor. First, the great power’s threat or inducements might not address the specific issue salient to the targeted ally. Second, the threats or inducements might also not address the specific timeframe related to compliance that is salient to the targeted ally. My dissertation has studied three cases of alliance conflicts primarily over the signing of armistices: the Korean War (1950-1953), the Vietnam War (1964-1973), and the Soviet-Afghan War (1979-1989). In each case, the superpower demanded an armistice while the ally refused. I argue that the allied government resisted due to the perception that the political threat to its rule would be more severe in case of compliance. I also argue that the noncompliance occurred because the threats and inducements did not coincide with the timeframe when the allied government felt greater security vulnerability. The allied governments in the case studies did “comply” eventually, but after the superpower addressed political concerns and timeframe that were salient to the allied government. This dissertation contributes to the alliance literature by studying intra-alliance conflicts from the weaker allies' perspective to show why weak allies sometimes do not comply and to understand better the gap in the cost perception between the great power and its allies.
