description: The enumeration of maps and the study of uniform random maps have been classical topics of combinatorics and statistical physics ever since the seminal work of Tutte in the sixties. Following the bijective approach initiated by Cori and Vauquelin in the eighties, we describe a bijection between rooted maps, or rooted bipartite quadrangulations, on a surface of genus g and some simpler objects that generalize plane trees. Thanks to a rerooting argument, our bijection allows to compute the generating series of rooted maps on a surface of genus g with respect to the number of edges, and to recover the asymptotic numbers of such maps. Our construction allows to keep track in a bipartite quadrangulation of the distances of all vertices to a random basepoint. This is an analog for higher genus surfaces of the basic result on which were built the recent advances in the comprehension of the intrinsec geometry of large random planar maps, hopefully opening the way to the study of a model of continuum random surfaces of genus g.

description: Biomedical applications at high-energy particle accelerators have always been an important section of the applied nuclear physics research. Several new facilities are now under constructions or undergoing major upgrades. While the main goal of these facilities is often basic research in nuclear physics, they acknowledge the importance of including biomedical research programs and of interacting with other medical accelerator facilities providing patient treatments. To harmonize the programs, avoid duplications, and foster collaboration and synergism, the International Biophysics Collaboration is providing a platform to several accelerator centers with interest in biomedical research. In this paper, we summarize the programs of various facilities in the running, upgrade, or construction phase.

description: PhishGuru is an embedded training system that teaches users to avoid falling for phishing attacks by delivering a training message when the user clicks on the URL in a simulated phishing email. In previous lab and real-world experiments, we validated the effectiveness of this approach. Here, we extend our previous work with a 515-participant, real-world study in which we focus on long-term retention and the effect of two training messages. We also investigate demographic factors that influence training and general phishing susceptibility. Results of this study show that (1) users trained with PhishGuru retain knowledge even after 28 days; (2) adding a second training message to reinforce the original training decreases the likelihood of people giving information to phishing websites; and (3) training does not decrease users’ willingness to click on links in legitimate messages. We found no significant difference between males and females in the tendency to fall for phishing emails both before and after the training. We found that participants in the 18-25 age group were consistently more vulnerable to phishing attacks on all days of the study than older participants. Finally, our exit survey results indicate that most participants enjoyed receiving training during their normal use of email.

Enumeration of n-Permutations Avoiding a Given k-Permutation
Creators: name: Snyder, Rachel Ann
Publisher: name: University of Illinois at Chicago
Year: 2024

description: This thesis is a survey of the research on enumerations of n-permutations that avoid a given k-permutation. It contains proofs for the nth Catalan number and there bijections between permutations that avoid a given 3-permutation and Dyck paths, allowing us to conclude that the number of n-permutations that avoid a given 3-permutation is 1/(n+1) (2n)Cn and that L(π) = 4 when π is a 3-permutation. This is followed by proving that L(123...k) = (k − 1). Marcus and Tardos' original proof of the Stanley-Wilf conjecture is explored, followed by contributions made to the field since the Stanley-Wilf conjecture was proven and a discussion of related open problems.
Structure factor of Bose-condensed systems

description: The structure factor for a Bose system with Bose-Einstein condensate is considered in the frame of the self-consistent mean-field approximation. The accomplished analysis demonstrates the principal importance of the following three points: the necessity of preserving the approximation order, the necessity of taking into account anomalous averages, and the necessity of gauge symmetry breaking. If any one of these necessary conditions is not satisfied, calculations yield the appearance of unphysical divergences of the structure factor, which implies the occurrence of fictitious instability, which contradicts experiments.

description: The quantity of dust in a spiral disk can be estimated using the dust's typical emission or the extinction of a known source. In this paper we compare two techniques, one based on emission and one on absorption, applied to sections of 14 disk galaxies. The two measurements reflect, respectively, the average and apparent optical depth of a disk section. Hence, they depend differently on the average number and optical depth of ISM structures in the disk. The small-scale geometry of the cold ISM is critical for accurate models of the overall energy budget of spiral disks. ISM geometry, relative contributions of different stellar populations, and dust emissivity are all free parameters in galaxy spectral energy distribution (SED) models; they are also sometimes degenerate, depending on wavelength coverage. Our aim is to constrain the typical ISM geometry. The apparent optical depth measurement comes from the number of distant galaxies seen in Hubble Space Telescope (HST) images through the foreground disk, calibrated with the synthetic field method (SFM). We discuss what can be learned from the SFM measurement alone regarding ISM geometry. We measure the IR flux in images from the Spitzer Infrared Nearby Galaxy Survey in the same section of the disk that was covered by HST. A physical model of the dust is fit to the SED to estimate the dust surface density, mean temperature, and brightness in these disk sections. The surface density is subsequently converted into the average optical depth estimate. The two measurements generally agree, and the SED model finds mostly cold dust (T < 25 K). The ratios between the measured average and apparent optical depths of the disk sections imply optically thin (τc = 0.4) clouds in these disks. Optically thick disks are likely to have more than a single cloud along the line of sight.

Large deviations for eigenvalues of sample covariance matrices, with applications to mobile communication systems

description: We study sample covariance matrices of the form $W=\frac 1n C C^T$, where $C$ is a $k\times n$ matrix with i.i.d. mean zero entries. This is a generalization of so-called Wishart matrices, where the entries of $C$ are independent and identically distributed standard normal random variables. Such matrices arise in statistics as sample covariance matrices, and the high-dimensional case, when $k$ is large, arises in the analysis of DNA experiments. We investigate the large deviation properties of the largest and smallest eigenvalues of $W$ when either $k$ is fixed and $n\to \infty$, or $k_n\to \infty$ with $k_n=o(n/\log\log{n})$, in the case where the squares of the i.i.d. entries have finite exponential moments. Previous results, proving a.s. limits of the eigenvalues, only require finite fourth moments. Our most explicit results for $k$ large are for the case where the entries of $C$ are $\pm1$ with equal probability. We relate the large deviation rate functions of the smallest and largest eigenvalue to the rate functions for independent and identically distributed standard normal entries of $C$. This case is of particular interest, since it is related to the problem of the decoding of a signal in a code division multiple access system arising in mobile communication systems. In this example, $k$ plays the role of the number of users in the system, and $n$ is the length of the coding sequence of each of the users. Each user transmits at the same time and uses the same frequency, and the codes are used to distinguish the signals of the separate users. The results imply large deviation bounds for the probability of a bit error due to the interference of the various users.

Tidal breakup of triple stars in the Galactic Centre
Creators: name: Fragione, Giacomo

Publisher: name: arXiv
Year: 2018
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: The last decade has seen the detection of fast moving stars in the Galactic halo, the so-called hypervelocity stars (HVSs). While the bulk of this population is likely the result of a close encounter between a stellar binary and the supermassive black hole (MBH) in the Galactic Centre (GC), other mechanims may contribute fast stars to the sample. Few observed HVSs show apparent ages which are shorter than the flight time from the GC, thereby making the binary disruption scenario unlikely. These stars may be the result of the breakup of a stellar triple in the GC which led to the ejection of a hypervelocity binary (HVB). If such binary evolves into a blue straggler star due to internal processes after ejection, a rejuvenation is possible that make the star appear younger once detected in the halo. A triple disruption may also be responsible for the presence of HVBs, of which one candidate has now been observed. We present a numerical study of triple disruptions by the MBH in the GC and find that the most likely outcomes are the production of single HVSs and single/binary stars bound to the MBH, while the production of HVBs has a probability $\lesssim 1\%$ regardless of the initial parameters. Assuming a triple fraction of $\approx 10\%$ results in an ejection rate of $\lesssim 1\ \mathrm{Gyr}^{-1}$, insufficient to explain the sample of HVSs with lifetimes shorter than their flight time. We conclude that alternative mechanisms are responsible for the origin of such objects and HVBs in general.

description: Web macros automate interactions with web sites and related information systems. Though web macro recorders and players have grown in sophistication over the past decade, these tools cannot yet meet many needs of users in daily life. Based on observations of browser users, we have compiled ten scenarios describing tasks that users would benefit from automating. Our analysis of these scenarios yields specific requirements that web macro tools should support if those tools are to be applicable to these real-life tasks. Our set of requirements constitutes a benchmark for evaluating tools.

description: We report magnetization and differential thermal analysis measurements as a function of pressure accross the martensitic transition in magnetically superelastic Ni-Mn-In alloys. It is found that the properties of the martensitic transformation are significantly affected by the application of pressure. All transition temperatures shift to higher values with increasing pressure. The largest rate of temperature shift with pressure has been found for Ni$_{50}$Mn$_{34}$In$_{16}$ as a consequence of its small entropy change at the transition. Such a strong pressure dependence of the transition temperature opens up the possibility of inducing the martensitic transition by applying relatively low hydrostatic pressures.

description: Space launches had been instrumental in medical improvements and satellite deployment. However, amid their significance, the environmental effect of these launches remains a vital problem. This summary explores the complicated interplay between rocket propulsion, atmospheric pollution, and ecological outcomes resulting from area launches.The evaluation spans the phases of a space launch, from ignition to ascent, highlighting emissions like carbon dioxide, soot, and water vapor launched into the ecosystem. These emissions result in localized disturbances and worldwide-scale influences, affecting atmospheric balance and potentially contributing to ozone layer depletion.The environmental results increase to terrestrial and marine ecosystems, with rocket launches posing dangers of ground and water contamination. Wildlife habitats close to release web sites face disruption, elevating concerns for biodiversity and ecosystem fitness.Mitigation techniques and technological advancements intention to reduce the environmental effect. Innovations in inexperienced propulsion technology and advanced launch web page designs align with environmental control practices to reduce the ecological footprint.Regulatory frameworks and collaborative efforts among stakeholders are crucial in addressing these environmental demanding situations. Emphasizing international cooperation, these frameworks play a pivotal role in balancing space exploration goals with environmental upkeep.Looking beforehand, sustainability in space launches is predicated on advancements in era, coverage interventions, and a concerted global dedication. This summary advocates for a future wherein space exploration coexists harmoniously with the vital of maintaining our planet's ecosystems.

description: In paper [1] (Avotina et al. Phys. Rev. B,74, 085411 (2006)) the effect of Fermi surface anisotropy to the conductance of a tunnel point contact, in the vicinity of which a single point-like defect is situated, has been investigated theoretically. The oscillatory dependence of the conductance on the distance between the contact and the defect has been found for a general Fermi surface geometry. In this paper we apply the method developed in [1] to the calculation of the conductance of noble metal contacts. An original algorithm, which enables the computation of the conductance for any parametrically given Fermi surface, is proposed. On this basis a pattern of the conductance oscillations, which can be observed by the method of scanning tunneling microscopy, is obtained for different orientations of the surface for the noble metals.

Police Behavior and Community Depression: A Mediation Mechanism
Creators: name: Dufelmeier, Daylan Dujon
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Depression is a common mental health problem with consequences ranging from mild impairment to complete incapacity. Depression amplifies co-occurring health conditions’ costs, putting people at risk for a range of cardiovascular diseases, pain, sleep disturbances and other mental health conditions. Exposure to stressors is recognized as a potential risk factor for developing depression. One attribute influencing one’s stressor exposure and available resources is the individual’s neighborhood. Typically assessed neighborhood elements include social disorder, gun violence, perceived safety and crime. This dissertation considers everyday police interactions, specifically arrests, at a community level and its relationship with depressive symptoms. The first aim evaluates the relationship and potential race differences in the relationship. The second aim examines the potential mechanism between community-level arrests, previous police encounters, perceptions of unfairness in police encounters—a measure capturing elements of procedural justice—and depressive symptoms. Using data from the Sinai Community Health Survey 2.0 (2015-16), the Chicago Police Department and the American Community Survey, this dissertation contributes to the sparse research on everyday policing as a community stressor and the growing consensus concerning procedural justice’s importance for police officers and community members.

description: We provide an efficient and general route for preparing non-trivial quantum states that are not adiabatically connected to unentangled product states. Our approach is a hybrid quantum-classical variational protocol that incorporates a feedback loop between a quantum simulator and a classical computer, and is experimentally realizable on near-term quantum devices of synthetic quantum systems. We find explicit protocols which prepare with perfect fidelities (i) the Greenberger-Horne-Zeilinger (GHZ) state, (ii) a quantum critical state, and (iii) a topologically ordered state, with $L$ variational parameters and physical runtimes $T$ that scale linearly with the system size $L$. We furthermore conjecture and support numerically that our protocol can prepare, with perfect fidelity and similar operational costs, the ground state of every point in the one dimensional transverse field Ising model phase diagram. Besides being practically useful, our results also illustrate the utility of such variational ansätze as good descriptions of non-trivial states of matter.

description: We study the thermodynamic properties of the black hole derived in Hořava-Lifshitz (HL) gravity without the detailed-balance condition. The parameter $Ξ=ε^2$ in the HL black hole plays the same role as that of the electric charge in the RN-AdS black hole. By analogy, we treat the parameter $Ξ$ as the thermodynamic variable and obtain the first law of thermodynamics for the HL black hole. Although the HL black hole and the RN-AdS black hole have the similar mass and temperature, due to their very different entropy the two black holes have very different thermodynamic properties. By calculating the heat capacity and the free energy we analyze the thermodynamic stability of the HL black hole.

description: This paper introduces a multiple-input discrete Urysohn operator for modelling non-linear control systems and a technique of its identification by processing the observed input and output signals. It is shown that, due to the nature of the discrete Urysohn operator, the identification problem always has an infinity of solutions, which exactly convert the inputs to the output. The suggested iterative identification procedure, however, leads to a unique solution with the minimum norm, requires only few arithmetic operations with the parameter values and is applicable to a real-time identification, running concurrently with the data reading. The efficiency of the proposed modelling and identification approaches is demonstrated using an example of a non-linear mechanical system, which is represented by a differential equation, and an example of a complex real-world dynamic object.
First-principles investigation of Ag-Cu alloy surfaces in an oxidizing environment

description: In this paper we investigate by means of first-principles density functional theory calculations the (111) surface of the Ag-Cu alloy under varying conditions of pressure of the surrounding oxygen atmosphere and temperature. This alloy has been recently proposed as a catalyst with improved selectivity for ethylene epoxidation with respect to pure silver, the catalyst commonly used in industrial applications. Here we show that the presence of oxygen leads to copper segregation to the surface. Considering the surface free energy as a function of the surface composition, we construct the convex hull to investigate the stability of various surface structures. By including the dependence of the free surface energy on the oxygen chemical potential, we are able compute the phase diagram of the alloy as a function of temperature, pressure and surface composition. We find that, at temperature and pressure typically used in ethylene epoxidation, a number of structures can be present on the surface of the alloy, including clean Ag(111), thin layers of copper oxide and thick oxide-like structures. These results are consistent with, and help explain, recent experimental results.

We present compelling numerical evidence for a universal spin-glass-like transition controlled by the protocol time duration. The glassy critical point is marked by a proliferation of protocols with close-to-optimal fidelity and with a true optimum that appears exponentially difficult to locate. Using a machine learning (ML) inspired framework based on the manifold learning algorithm t-SNE, we are able to visualize the geometry of the high-dimensional control landscape in an effective low-dimensional representation. Across the transition, the control landscape features an exponential number of clusters separated by extensive barriers, which bears a strong resemblance with replica symmetry breaking in spin glasses and random satisfiability problems. We further show that the quantum control landscape maps onto a disorder-free classical Ising model with frustrated nonlocal, multibody interactions. Our work highlights an intricate but unexpected connection between optimal quantum control and spin glass physics, and shows how tools from ML can be used to visualize and understand glassy optimization landscapes.

description: Access to large numbers of data sources introduces new problems for users of heterogeneous distributed databases. End users and application programmers must deal with unavailable data sources. Database administrators must deal with incorporating new sources into the model. Database implementors must deal with the translation of queries between query languages and schemas. The Distributed Information Search COmponent (Disco) addresses these problems. Query processing semantics are developed to process queries over data sources which do not return answers. Data modeling techniques manage connections to data sources. The component interface to data sources flexibly handles different query languages and translates queries. This paper describes (a) the distributed mediator architecture of Disco, (b) its query processing semantics, (c) the data model and its modeling of data source connections, and (d) the interface to underlying data sources.

description: The Mach-Zehnder interferometric setup quantitatively characterizing the wave-particle duality implements in fact a joint measurement of two unsharp observables. We present a necessary and sufficient condition for such a pair of unsharp observables to be jointly measurable. The condition is shown to be equivalent to a duality inequality, which for the optimal strategy of extracting the which-path information is more stringent than the Jaeger-Shimony-Vaidman-Englert inequality.

description: Arch arised as structural system more than two thousand years ago, but, in spite of this, it is still not widely diffused and is mainly adopted in presence of large spans. The structural efficiency of arches primarily depends on optimal material exploitation, i.e. minimization of internal stress eccentricity that reduces structural material volume and weight. An efficient structure, under these terms, leads to simple and light scaffolding, so contributing in minimizing construction costs. So, although literature on arches is already significant, there is still scope for design optimization. This study is framed within this context and deals with the structural analysis of end perfectly-constrained plane circular arches under uniformly distributed vertical load and self weight. In the first step, the analytical solution of arch static and kinematic behaviour is obtained by applying the force method. In the second step, the arch shape is optimized, by assuming the arch volume, and thus the weight, as objective function. Finally minima of the objective function (i.e. optimal geometric shape parameters) are computed and plotted in order to be used for practical purposes.

The Effects of Racial Identity and Racial Discrimination on Black Mental Health Service Use

description: Abstract

Growing diversity in the Black Diaspora and increases in mental health concerns among Black people indicate a need for exploring the factors that influence the mental health practices of Black people. Racial identity and racial discrimination may be significant predictors of mental health service use; however, variability in Black historical context and experiences in the U.S. suggest that these factors may operate differently by Black ethnic group.
In this dissertation, data from the National Survey of American Life (NSAL) was used to examine how racial identity and racial discrimination influence mental health support-seeking behavior among African Americans and Caribbean Blacks. In the first study, we identified classes of racial identity and examined whether these classes determine mental health service use. Racial identity characterized by a strong sense of racial pride, centrality of race, and social and political autonomy of Black people (Pride-Nationalist) is associated with lower odds of mental health service use. In contrast, racial identity characterized by the belief that people of other races have positive perceptions of Blacks was associated with more mental health service use.
In the second study, we identified three distinct mental health support classes (Family-Friends/Clergy, Informal Support, and All Supports) and examined whether racial identity predicts class membership. High private regard is associated with a greater likelihood of being in the Family-Friends/Clergy class than the other two classes among African Americans and Caribbeans. On the other hand, high racial ideology was associated with a greater likelihood of being in the All Supports class among Caribbean Blacks.
In the third study, we examined the moderating role of racial identity on the association between racial discrimination and mental health. More experiences with racial discrimination was associated with more mental health service use. Among Caribbean Blacks with high centrality, racial discrimination was associated with a lower likelihood of mental health service use.
Collectively our findings fill a gap in our understanding of how racial identity influences Black mental health support-seeking behavior. Furthermore, our results highlight the significance of informal support sources for Black mental well-being.

description: A quantitative analysis of the excitonic luminescence efficiency in hexagonal boron nitride (hBN) is carried out by cathodoluminescence in the ultraviolet range and compared with zinc oxide and diamond single crystals. A high quantum yield value of ~50% is found for hBN at 10 K comparable to that of direct bandgap semiconductors. This bright luminescence at 215 nm remains stable up to room temperature, evidencing the strongly bound character of excitons in bulk hBN. Ab initio calculations of the exciton dispersion confirm the indirect nature of the lowest-energy exciton whose binding energy is found equal to 300 meV, in agreement with the thermal stability observed in luminescence. The direct exciton is found at a higher energy but very close to the indirect one, which solves the long debated Stokes shift in bulk hBN.

Scaling Access to Heterogeneous Databases with DISCO

description: Accessing many data sources aggravates problems for users of heterogeneous distributed databases. Database administrators must deal with fragile mediators, that is, mediators with schemas and views that must be significantly changed to incorporate a new data source. When implementing translators of queries from mediators to data sources, database implementors must deal with data sources that do not support all the functionality required by mediators. Application programmers must deal with graceless failures for unavailable data sources. Queries simply return failure and no further information when data sources are unavailable for query processing. The Distributed Information Search COmponent (DISCO) addresses these problems. Data modeling techniques manage the connections to data sources, and sources can be added transparently to the users and applications. The interface between mediators and data sources flexibly handles different query languages and different data source functionality. Query rewriting and optimization techniques rewrite queries so they are efficiently evaluated by sources. Query processing and evaluation semantics are developed to process queries over unavailable data sources. In this article we describe (a) the distributed mediator architecture of DISCO; (b) the data model and its modeling of data source connections; (c) the interface to underlying data sources and the query rewriting process; and (d) query processing semantics. We describe several advantages of our system.
