description: Lifetime distributions of social entities, such as enterprises, products, and media contents, are one of the fundamental statistics characterizing the social dynamics. To investigate the lifetime distribution of mutually interacting systems, simple models having a rule for additions and deletions of entities are investigated. We found a quite universal lifetime distribution for various kinds of inter-entity interactions, and it is well fitted by a stretched-exponential function with an exponent close to 1/2. We propose a "modified Red-Queen" hypothesis to explain this distribution. We also review empirical studies on the lifetime distribution of social entities, and discussed the applicability of the model.

description: In photon-dominated regions (PDRs), UV photons from nearby stars lead to the evaporation of very small grains (VSGs) and the production of gas-phase polycyclic aromatic hydrocarbons (PAHs). Our goal is to achieve better insight into the composition and evolution of evaporating very small grains (eVSGs) and PAHs through analyzing the infrared (IR) aliphatic and aromatic emission bands. We combined spectro-imagery in the near- and mid-IR to study the spatial evolution of the emission bands in the prototypical PDR NGC 7023. We used near-IR spectra obtained with AKARI to trace the evolution of the 3.3$μ$m and 3.4$μ$m bands, which are associated with aromatic and aliphatic C-H bonds on PAHs. The spectral fitting involves an additional broad feature centred at 3.45$μ$m. Mid-IR observations obtained with Spitzer are used to discriminate the signatures of eVSGs, neutral and cationic PAHs. We correlated the spatial evolution of all these bands with the intensity of the UV field to explore the processing of their carriers. The intensity of the 3.45$μ$m plateau shows an excellent correlation with that of the 3.3$μ$m aromatic band (correlation coefficient R = 0.95), indicating that the plateau is dominated by the emission from aromatic bonds. The ratio of the 3.4$μ$m and 3.3$μ$m band intensity ($I_{3.4}/I_{3.3}$) decreases by a factor of 4 at the PDR interface from the more UV-shielded to the more exposed layers. The transition region between the aliphatic and aromatic material is found to correspond spatially with the transition zone between neutral PAHs and eVSGs. We conclude that the photo-processing of eVSGs leads to the production of PAHs with attached aliphatic sidegroups that are revealed by the 3.4$μ$m emission band. Our analysis provides evidence for the presence of very small grains of mixed aromatic and aliphatic composition in PDRs.

description: The turbulent dynamo may explain the origin of cosmic magnetism. While the exponential amplification of magnetic fields has been studied for incompressible gases, little is known about dynamo action in highly-compressible, supersonic plasmas, such as the interstellar medium of galaxies and the early Universe. Here we perform the first quantitative comparison of theoretical models of the dynamo growth rate and saturation level with three-dimensional magnetohydrodynamical simulations of supersonic turbulence with grid resolutions of up to 1024^3 cells. We obtain numerical convergence and find that dynamo action occurs for both low and high magnetic Prandtl numbers Pm = nu/eta = 0.1-10 (the ratio of viscous to magnetic dissipation), which had so far only been seen for Pm >= 1 in supersonic turbulence. We measure the critical magnetic Reynolds number, Rm_crit = 129 (+43, -31), showing that the compressible dynamo is almost as efficient as in incompressible gas. Considering the physical conditions of the present and early Universe, we conclude that magnetic fields need to be taken into account during structure formation from the early to the present cosmic ages, because they suppress gas fragmentation and drive powerful jets and outflows, both greatly affecting the initial mass function of stars.

“The Social Life of the Socially Dead”: Gentrification and Displacement in the Five Points District of Denver, Colorado
Creators: name: Bruton, Stephanie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: The establishment of historically Black towns and districts across the United States provided
African Americans a sense of agency through developing wealth, residency, and sustainable
businesses. Such areas highlighted the formation of hubs of Black affluence, which grounded the
economy and infrastructure of such towns and generated community morale. However, these
minority communities face the threat of gentrification when external groups relocate into these
distinct areas and introduce other forms of commerce. Black citizens have often been forced out
of these areas into surrounding cities and must attempt to rebuild their former identities
elsewhere. Such is the case with Five Points, Denver, Colorado, which began as a hub of Black
social advancement and a base for transient job opportunities. Ironically, its vibrant economic
base became a key contributor to its subsequent downfall. This article seeks to examine the Five
Points Historical Black District through a historical lens. It presents recommendations for the
current planning and redesigning of the neighborhood, pointing out factors that might further
prevent former and current Black residents from regaining a sense of self, both financially and
socially. The case study of Five Points also allows room for discussion concerning issues of
gentrification and the subsequent social death of the Black community in Colorado. The article
ends by comparing the gentrification of Five Points to the Hayti District of Durham, North
Carolina to demonstrate that such patterns are present in the larger, nationwide context.
Sampling Sparse Signals on the Sphere: Algorithms and Applications

description: We propose a sampling scheme that can perfectly reconstruct a collection of spikes on the sphere from samples of their lowpass-filtered observations. Central to our algorithm is a generalization of the annihilating filter method, a tool widely used in array signal processing and finite-rate-of-innovation (FRI) sampling. The proposed algorithm can reconstruct $K$ spikes from $(K+\sqrt{K})^2$ spatial samples. This sampling requirement improves over previously known FRI sampling schemes on the sphere by a factor of four for large $K$. We showcase the versatility of the proposed algorithm by applying it to three different problems: 1) sampling diffusion processes induced by localized sources on the sphere, 2) shot noise removal, and 3) sound source localization (SSL) by a spherical microphone array. In particular, we show how SSL can be reformulated as a spherical sparse sampling problem.

Black Dollar, Mixed City: A Comparative Analysis of Durham, North Carolina’s “Black Wall Street” and the Political Philosophy of Booker T. Washington
Creators: name: Biggs, Jorren
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: In the early twentieth century, Booker T. Washington stood as one of the foremost thinkers on
the state of Black America. His influence on the perception of Black advancement came at a
period that saw the financial burgeoning of numerous Black neighborhoods and communities
across the country. Durham, North Carolina’s Hayti community, often referred to as “Black Wall
Street,” stands as a unique case in the larger development of Black communities across the
country due to its length of existence and relatively peaceful relationship with the city’s white
establishment. This article seeks to explore what enabled Hayti to play host to sustained
development, by analyzing population metrics, media accounts of the community’s development,
and biographical information about business leaders of the period. The article also examines the
relationship between white benevolence and Black progress. Through exploring how the
changing political landscape of North Carolina may have guided actions by groups like the Duke
family, this article offers a critical perspective of the role white leaders had in the community’s
expansion. Further, Hayti will be used as a site to test the economic theories posited by
Washington. As Washington’s public politics largely called for investment into manual labor
education to spur Black progress, how might Hayti have pushed back against efforts to limit
engagement with skilled labor?
Understanding the Complexities of the Black Press in Chicago during the Interwar Years: The Influence and History of the Chicago Defender
Creators: name: Webb, Susie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: The Black press in Chicago after World War I became a builder of community and a platform for
social change. Led by the Chicago Defender in the 1920s, the Black press pushed for the
advancement of Black rights, acted as a racial watchdog, and contributed to a Black cultural
revival in Chicago. The Chicago Defender published Black news that white papers—which often
only covered incidents of Black violence—wouldn’t. These positive stories helped the Chicago
Defender redefine what it meant to be Black, giving Black communities in Chicago, and beyond,
a space of their own. However, issues of the Chicago Defender during the interwar period
predominately featured sensationalized race-associated violence as their front-page stories—even
if the paper covered positive news inside. I conducted an independent review of these issues to
determine the extent of the front-page sensationalism and found the prevalence of yellow
journalism tactics to appeal to readers. The paper also reflected the elitist views of its editors, and
it published advertisements promoting white beauty standards in its women’s pages. In analyzing
the Chicago Defender’s influence on Chicago and its role in the formation of the Black press, it
is important to holistically consider its history—good and bad.

description: The performances of braking control systems for robotic platforms, e.g., assisted and autonomous vehicles, airplanes and drones, are deeply influenced by the road-tire friction experienced during the maneuver. Therefore, the availability of accurate estimation algorithms is of major importance in the development of advanced control schemes. The focus of this paper is on the estimation problem. In particular, a novel estimation algorithm is proposed, based on a multi-layer neural network. The training is based on a synthetic data set, derived from a widely used friction model. The open loop performances of the proposed algorithm are evaluated in a number of simulated scenarios. Moreover, different control schemes are used to test the closed loop scenario, where the estimated optimal slip is used as the set-point. The experimental results and the comparison with a model based baseline show that the proposed approach can provide an effective best slip estimation.
Nkrumaism: Ideological Syncretism in the Anti-Colonial Political Imaginary
Creators: name: Nikoi, Cho
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: In this article, I explore the role of varied educational, environmental, and political forces in
Kwame Nkrumah’s ideological orientation. I argue against a popular impulse to portray African
colonial elites as ideologically passive, merely supplanting Western thought systems into the
postcolony—often unsuccessfully. Though various historical cases provide evidence for such a
position, here I argue against analyses that characterize Nkrumah as non-agential in his
intellectual and political development. Rather, I demonstrate that he drew inspiration from
diverse educational environments, from the colonial Gold Coast, to the Ivy League and
historically Black colleges of the American Northeast, to student-activist spheres in London.
Armed with expertise in philosophy and theology, Nkrumah engaged with his contemporaries in
the Pan-African liberation struggle to birth visions of novel political forms and ideals. In
particular, I focus on the development and deployment of consciencism—a hybrid political
philosophy that aimed to illustrate the multiplicity of the African condition. This article employs
some comparative methods in assessing the ideological divergences between American-educated
colonial elites (such as Nkrumah) and their British-educated counterparts. However, the overall
methodology is a global one, emphasizing the manner in which ideas traveled anti-colonial
circuits and adapted to suit particular conditions.
Ion-specific colloidal aggregation: population balance equations and potential of mean force

Year: 2014
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Recently reported colloidal aggregation data obtained for different monovalent salts (NaCl, NaNO$_3$, and NaSCN) and at high electrolyte concentrations are matched with the stochastic solutions of the master equation to obtain bond average lifetimes and bond formation probabilities. This was done for a cationic and an anionic system of similar particle size and absolute charge. Following the series Cl$^-$, NO$_3^-$, SCN$^-$, the parameters obtained from the fitting procedure to the kinetic data suggest: i) The existence of a potential of mean force (PMF) barrier and an increasing trend for it for both latices. ii) An increasing trend for the PMF at contact, for the cationic system, and a practically constant value for the anionic system. iii) A decreasing trend for the depth of the secondary minimum. This complex behavior is in general supported by Monte Carlo simulations, which are implemented to obtain the PMF of a pair of colloidal particles immersed in the corresponding electrolyte solution. All these findings contrast the Derjaguin, Landau, Verwey, and Overbeek theory predictions.

Tensorflow-based Maximum Likelihood fits for High Precision Standard Model Measurements at CMS
Creators: name: Bendavid, Josh
Publisher: name: Zenodo
Year: 2020

description: With increasing integrated luminosity at the LHC, highly differential and extremely precise measurements of Standard Model processes become possible. This imposes stringent requirements for accurate modelling of systematic uncertainties of both experimental and theoretical origin. One possible method for the unfolding of detector response is the use of maximum likelihood fits, with systematic uncertainties represented by nuisance parameters. Precise Standard Model measurements in Run 2 already pose a challenge with respect to the speed and stability of Standard Tools. A Tensorflow-based implementation for binned maximum likelihood fits has been used for the unfolding and statistical interpretation of high precision differential cross section measurements of W boson production recently released by CMS, involving maximum likelihood fits including hundreds of millions of events, with hundreds of measured cross sections and over a thousand nuisance parameters. This has led to huge benefits in terms of speed, stability, and flexibility for the sophistication of the measurement and systematic uncertainties, as well as statistical interpretation.

description: We perform radiation-hydrodynamics simulations of binary neutron star mergers in numerical relativity on the Japanese "K" supercomputer, taking into account neutrino cooling and heating by an updated leakage-plus-transfer scheme for the first time. Neutron stars are modeled by three modern finite-temperature equations of state (EOS) developed by Hempel and his collaborators. We find that the properties of the dynamical ejecta of the merger such as total mass, average electron fraction, and thermal energy depend strongly on the EOS. Only for a soft EOS (the so-called SFHo), the ejecta mass exceeds $0.01M_{\odot}$. In this case, the distribution of the electron fraction of the ejecta becomes broad due to the shock heating during the merger. These properties are well-suited for the production of the solar-like $r$-process abundance. For the other stiff EOS (DD2 and TM1), for which a long-lived massive neutron star is formed after the merger, the ejecta mass is smaller than $0.01M_{\odot}$, although broad electron-fraction distributions are achieved by the positron capture and the neutrino heating.

Matter Power Spectra in Viable $f(R)$ Gravity Models with Massive Neutrinos

description: We investigate the matter power spectra in the power law and exponential types of viable $f(R)$ theories along with massive neutrinos. The enhancement of the matter power spectrum is found to be a generic feature in these models. In particular, we show that in the former type, such as the Starobinsky model, the spectrum is magnified much larger than the latter one, such as the exponential model. A greater scale of the total neutrino mass, $Σm_ν$, is allowed in the viable $f(R)$ models than that in the $Λ$CDM one. We obtain the constraints on the neutrino masses by using the CosmoMC package with the modified MGCAMB. Explicitly, we get $Σm_ν < 0.451 \ (0.214)\ \mathrm{eV}$ at 95% C.L. in the Starobinsky (exponential) model, while the corresponding one for the $Λ$CDM model is $Σm_ν < 0.200\ \mathrm{eV}$. Furthermore, by treating the effective number of neutrino species $N_{\mathrm{eff}}$ as a free parameter along with $Σm_ν$, we find that $N_{\mathrm{eff}} = 3.78^{+0.64}_{-0.84} (3.47^{+0.74}_{-0.60})$ and $Σm_ν = 0.533^{+0.254}_{-0.411}$ ($< 0.386) \ \mathrm{eV}$ at 95% C.L. in the Starobinsky (exponential) model.

Year: 2023

description: In her book Body and Soul: The Black Panther Party and the Fight Against Medical
Discrimination, historian Alondra Nelson addresses the social and political context that
influenced the rise of health activism in the African American community, and the role of the
Black Panther Party in this movement. Body and Soul reveals ways in which access to healthcare
becomes politicized, and through that becomes racialized. Primarily, Nelson draws upon the
firsthand accounts of former members or supporters of the Black Panthers as well as official
government documents and public media to thoroughly illustrate the significance of the health
activism of the Black Panther Party throughout the 1960s and 1970s. Using these sources,
Nelson describes the evolution of the Black Panther Party from an organization that simply stood
for self-defense to one that also advocated for sociopolitical reform and improvements in African
American healthcare.

description: Recent developments in computer technology have increased the number of internet stalkers, child pornographers, traffickers and sexual predators. In a world where digital literacy is on the rise and people strive to keep up with the latest technology, this paper explores the relationship between digital literacy and online grooming(computer-mediated sexual grooming) and offline grooming (localized sexual grooming) and the effect of age, gender, marital status and parental status on the way individuals perceive grooming. This data was collected via a survey from 256 respondents who are 18 years and above and classified as parents within the United States. Several analyses such as correlations, Mann-Whitney U test and Kruskal Wallis H test were conducted, and our results suggest that there is a relationship between digital literacy and the perceptions of grooming, which may have implications on cybersecurity awareness training. The results highlight the importance of digital literacy in the perception of computer-mediated sexual grooming and familial sexual grooming, with enough evidence to support its essential role in people’s sense of safety. In conclusion, this study emphasized the need for targeted programs and campaigns to create education and awareness with the aim of improving parental digital literacy skills, understanding of grooming risks, and responsible Internet use education across society.

description: Speech quality assessment has been a critical component in many voice communication related applications such as telephony and online conferencing. Traditional intrusive speech quality assessment requires the clean reference of the degraded utterance to provide an accurate quality measurement. This requirement limits the usability of these methods in real-world scenarios. On the other hand, non-intrusive subjective measurement is the ``golden standard" in evaluating speech quality as human listeners can intrinsically evaluate the quality of any degraded speech with ease. In this paper, we propose a novel end-to-end model structure called Convolutional Context-Aware Transformer (CCAT) network to predict the mean opinion score (MOS) of human raters. We evaluate our model on three MOS-annotated datasets spanning multiple languages and distortion types and submit our results to the ConferencingSpeech 2022 Challenge. Our experiments show that CCAT provides promising MOS predictions compared to current state-of-art non-intrusive speech assessment models with average Pearson correlation coefficient (PCC) increasing from 0.530 to 0.697 and average RMSE decreasing from 0.768 to 0.570 compared to the baseline model on the challenge evaluation test set.
Constant-force approach to discontinuous potentials

description: Aiming to approach the thermodynamical properties of hard-core systems by standard molecular dynamics simulation, we propose setting a repulsive constant-force for overlapping particles. That is, the discontinuity of the pair potential is replaced by a linear function with a large negative slope. Hence, the core-core repulsion, usually modeled with a power function of distance, yields a large force as soon as the cores slightly overlap. This leads to a quasi-hardcore behavior. The idea is tested for a triangle potential of short range. The results obtained by replica exchange molecular dynamics for several repulsive forces are contrasted with the ones obtained for the discontinuous potential and by means of replica exchange Monte Carlo. We found remarkable agreements for the vapor-liquid coexistence densities as well as for the surface tension.

description: We propose a model that generates a new class of networks exhibiting power-law degree distribution with a spectrum of exponents depending on the number of links ($m$) with which incoming nodes join the existing network. Unlike the Barabási-Albert (BA) model, each new node first picks an existing node at random, and connects not with this but with $m$ of its neighbors also picked at random. Counterintuitively enough, such a mediation-driven attachment rule results not only in preferential but super-preferential attachment, albeit in disguise. We show that for small $m$, the dynamics of our model is governed by winners take all phenomenon, and for higher $m$ it is governed by winners take some. Besides, we show that the mean of the inverse harmonic mean of degrees of the neighborhood of all existing nodes is a measure that can well qualify how straight the degree distribution is.

description: Three-dimensional convection driven by internal heat sources and sinks (CISS) leads to experimental and numerical scaling-laws compatible with a mixing-length - or `ultimate' - scaling regime $Nu \sim \sqrt{Ra}$. However, asymptotic analytic solutions and idealized 2D simulations have shown that laminar flow solutions can transport heat even more efficiently, with $Nu \sim Ra$. The turbulent nature of the flow thus has a profound impact on its transport properties. In the present contribution we give this statement a precise mathematical sense. We show that the Nusselt number maximized over all solutions is bounded from above by const.$\times Ra$, before restricting attention to 'fully turbulent branches of solutions', defined as families of solutions characterized by a finite nonzero limit of the dissipation coefficient at large driving amplitude. Maximization of $Nu$ over such branches of solutions yields the better upper-bound $Nu \lesssim \sqrt{Ra}$. We then provide 3D numerical and experimental data of CISS compatible with a finite limiting value of the dissipation coefficient at large driving amplitude. It thus seems that CISS achieves the maximal heat transport scaling over fully turbulent solutions.

Wendland uses medical case studies, interviews, and contextual evidence to explain why women
in Malawi perish from giving birth, while also recognizing the ambiguity inherent in any single
explanation for maternal death. She highlights this ambiguity by examining competing
explanations for high rates of maternal death from researchers and caregivers worldwide. Each
chapter of the book is focused on one of the main explanations that circulate to explain maternal
death, discussing what each explanation contributes and leaves out. As such, Wendland
ultimately concludes that no one reason can fully explain what drives high maternal mortality
rates. Rather, she finds that the complex reasons for maternal death depend on multiple factors
and actors.

description: In this paper, we analyze the rotating Einstein-non-linear-Maxwell-Yukawa black hole solution by Janis-Newman algorithmic rule and complex calculations. We investigate the basic properties (i.e., Hawking radiation) for the corresponding black hole solution. From the horizon structure of the black hole, we discuss the graphical behavior of Hawking temperature $T_H$ and analyze the effects of spin parameter (appears due to Newman-Janis approach) on the $T_H$ of black hole. Furthermore, we investigate the corrected temperature for rotating Einstein-non-linear-Maxwell-Yukawa black hole by using the vector particles tunneling strategy which is based on Hamilton-Jacobi method. We additionally study the graphical explanation of corrected $T_H$ through outer horizon to investigate the physical and stable conditions of black hole. Finally, we compute the corrected entropy and check that the effect of charged, rotation and gravity on entropy.

description: Why life persists at the edge of chaos is a question at the very heart of evolution. Here we show that molecules taking part in biochemical processes from small molecules to proteins are critical quantum mechanically. Electronic Hamiltonians of biomolecules are tuned exactly to the critical point of the metal-insulator transition separating the Anderson localized insulator phase from the conducting disordered metal phase. Using tools from Random Matrix Theory we confirm that the energy level statistics of these biomolecules show the universal transitional distribution of the metal-insulator critical point and the wave functions are multifractals in accordance with the theory of Anderson transitions. The findings point to the existence of a universal mechanism of charge transport in living matter. The revealed bio-conductor material is neither a metal nor an insulator but a new quantum critical material which can exist only in highly evolved systems and has unique material properties.

Study of Intra-Day Flux Distributions of Blazars Using XMM-Newton Satellite

description: We present a study of the flux distribution of a sample of 15 Intermediate and Low-energy peaked blazars using XMM-Newton observations in a total of 57 epochs on short-term timescales. We characterise the X-ray variability of all of the light curves using excess fractional variability amplitude and found that only 24 light curves in 7 sources are significantly variable. In order to characterise the origin of X-ray variability in these blazars, we fit the flux distributions of all these light curves using Gaussian and lognormal distributions, as any non-Gaussian perturbation could indicate the imprints of fluctuations in the accretion disc, which could be Doppler boosted through the relativistic jets in blazars. However, intra-day variability, as seen in our observations, is difficult to reconcile using disc components as the emissions in such sources are mostly dominated by jets. We used Anderson-Darling (AD) and $χ^{2}$ tests to fit the histograms. In 11 observations of 4 blazars, namely, ON 231, 3C 273, PKS 0235+164 and PKS 0521-365, both models equally fit the flux distributions. In the rest of the observations, we are unable to model them with any distribution. In two sources, namely, BL Lacertae and S4 0954+650, the lognormal distribution is preferred over the normal distribution, which could arise from non-Gaussian perturbations from relativistic jets or linear Gaussian perturbation in the particle time scale leading to such flux distributions.

Marxist and Formless: Uncanny Materialism in Peter Weiss’s The Aesthetics of Resistance
Creators: name: Langston, Richard
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Peter Weiss made no secret of the importance of form for his magnum opus The Aesthetics of Resistance. “Again and again [I’ve made] new attempts at finding a form for the book,” he wrote early on in its conception. This authorial search is, in fact, far more complicated than the long blocks of prose Weiss settled on for the novel. Exemplified in volume 2’s opening confrontation with Théodore Géricault’s painting The Raft of the Medusa, this search within the narrative vacillates between constituting erect forms and leveling them altogether. With the aid of Georges Bataille, the following essay illuminates not only how reading and writing embody these oppositions between form and formless but also how this tension culminates in Weiss’s poetic regeneration of a Marxism uncanny in nature despite what he perceived as dialectical materialism’s bureaucratic exhaustion in the Eastern bloc.
Ultrasensitive Surface-Enhanced Raman Spectroscopy Detection by Porous Silver Supraparticles from Self-Lubricating Drop Evaporation

description: This work demonstrates an original and ultrasensitive approach for surface-enhanced Raman spectroscopy (SERS) detection based on evaporation of self-lubricating drops containing silver supraparticles. The developed method detects an extremely low concentration of analyte that is enriched and concentrated on sensitive SERS sites of the compact supraparticles formed from drop evaporation. A low limit of detection of 10^-16 M is achieved for a model hydrophobic compound rhodamine 6G (R6G). The quantitative analysis of R6G concentration is obtained from 10^-5 to 10^-11 M. In addition, for a model micro-pollutant in water triclosan, the detection limit of 10^-6 M is achieved by using microliter sample solutions. The intensity of SERS detection in this approach is robust to the dispersity of the nanoparticles in the drop but became stronger after a longer drying time. The ultrasensitive detection mechanism is the sequential process of concentration, extraction, and absorption of the analyte during evaporation of self-lubrication drop and hot spot generation for intensification of SERS signals. This novel approach for sample preparation in ultrasensitive SERS detection can be applied to the detection of chemical and biological signatures in areas such as environment monitoring, food safety, and biomedical diagnostics.

description: The XMM-Newton X-ray observatory has repeatedly observed the CDFS in 33 epochs (2001-2010) through the XMM-CDFS Deep Survey. During the X-ray observations, XMM-OM targeted the central 17x17 arcmin2 region of the X-ray field of view, providing simultaneous optical/UV coverage of the CDFS. The resulting set of data can be used to build an XMM-OM catalogue of the CDFS, filling the UV spectral coverage between the optical surveys and GALEX observations. We present the UV catalogue of the XMM-CDFS Deep Survey. Its main purpose is to provide complementary UV average photometric measurements of known optical/UV sources in the CDFS, taking advantage of the unique characteristics of the survey. The data reduction is also intended to improve the standard source detection on individual observations, by cataloguing faint sources by stacking their exposure images. We reprocessed the XMM-OM data of the survey and stacked the exposures from consecutive observations using the standard SAS tools to process the data obtained during single observations. Average measurements of detections with SAS good quality flags from individual observations and from stacked images were joined to compile the catalogue. Sources were validated through the cross-identification within the EIS and COMBO-17 surveys. Photometric data of 1129 CDFS sources are provided in the catalogue, and optical/UV/X-ray photometric and spectroscopic information from other surveys are also included. The stacking extends the detection limits by ~1 mag in the three UV bands, contributing 30% of the catalogued UV sources. The comparison with the available measurements in similar spectral bands confirms the validity of the XMM-OM calibration. The combined COMBO-17/X-ray classification of the "intermediate" sources (e.g. optically diluted and/or X-ray absorbed AGN) is also discussed.

description: Person re-identification is a critical privacy breach in publicly shared healthcare data. We investigate the possibility of a new type of privacy threat on publicly shared privacy insensitive large scale wearable sensing data. In this paper, we investigate user specific biometric signatures in terms of two contextual biometric traits, physiological (photoplethysmography and electrodermal activity) and physical (accelerometer) contexts. In this regard, we propose PhysioGait, a context-aware physiological signal model that consists of a Multi-Modal Siamese Convolutional Neural Network (mmSNN) which learns the spatial and temporal information individually and performs sensor fusion in a Siamese cost with the objective of predicting a person's identity. We evaluated PhysioGait attack model using 4 real-time collected datasets (3-data under IRB #HP-00064387 and one publicly available data) and two combined datasets achieving 89% - 93% accuracy of re-identifying persons.
