description: Risk-based authentication (RBA) aims to protect end-users against attacks involving stolen or otherwise guessed passwords without requiring a second authentication method all the time. Online services typically set limits on what is still seen as normal and what is not, as well as the actions taken afterward. Consequently, RBA monitors different features, such as geolocation and device during login. If the features' values differ from the expected values, then a second authentication method might be requested. However, only a few online services publish information about how their systems work. This hinders not only RBA research but also its development and adoption in organizations. In order to understand how the RBA systems online services operate, black box testing is applied. To verify the results, we re-evaluate the three large providers: Google, Amazon, and Facebook. Based on our test setup and the test cases, we notice differences in RBA based on account creation at Google. Additionally, several test cases rarely trigger the RBA system. Our results provide new insights into RBA systems and raise several questions for future work.
Genderizzazione degli agenti artificiali: stereotipi e pregiudizi nell’IA

description: Quello della robotica sociale è un settore di ricerca che, a partire dagli ultimi decenni del secolo scorso, ha conosciuto una crescita sempre più massiccia. Essendo destinati ad entrare, in un futuro ormai non troppo remoto, nelle nostre case e in buona parte della società, questi agenti artificiali di nuova generazione impongono delle riflessioni che intrecciano strettamente il campo delle scienze matematiche ed ingegneristiche con quello delle scienze umane. Poiché, tra le sue innumerevoli caratteristiche, uno dei punti cardine della robotica sociale è quello di favorire un’interazione sostenibile e basata sulla fiducia tra robot ed esseri umani, spesso entra in azione quel meccanismo che involontariamente trasferisce ai robot quelle caratteristiche che solitamente tendiamo ad attribuire ai nostri simili. Tra queste rientra a pieno titolo anche l’attribuzione di un genere e, assumendo spesso una visione stereotipata della società, anche dei conseguenti ruoli occupazionali che gli vengono destinati.

Don't Call the Police? Measuring and Explaining the Dark Figure of Crime in the Context of Chile
Creators: name: Latezo, Isabel G.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Studies of crime and violence are often hindered by unreliable data. Thus, researchers predom- inantly rely on homicide statistics, considered the most accurate crime measure. However, this measure has been shown to have its own biases and does not accurately reflect the nature of all crime rates. This paper illustrates a new method in which scholars and practitioners can determine the size of the “dark figure,” or gap between officially reported crimes and surveyed victimization rates, for non-homicides. This measure can be leveraged to improve analyses of non-homicidal crimes, and understand the inaccuracies in official crime data. The paper demonstrates an application in Chile and estimates the dark figure for the majority of urban communities across the country. Further, it explores one of the main explanations for the dark figure - crime underreporting - in the context of Chile. It tests how individuals’ perceptions of government, including trust in institutions and perceptions of state capacity, affect the probability of reporting crimes. It finds mixed results for the explanatory role of these perceptions.

description: Data breaches resulting from targeted attacks against organizations, e.g., by advanced persistent threat groups, often involve social engineering (SE) as the initial attack vector before malicious software is used, e.g., for persistence, lateral movement, and data exfiltration. While technical security controls, such as the automated detection of phishing emails, can contribute to mitigating SE risks, raising awareness for SE attacks through education and motivation of personnel is an important building block to increasing an organization's resilience. To facilitate hands-on SE awareness training as one component of broader SE awareness campaigns, we created a SE tabletop game called Tabletop As Social Engineering Prevention (TASEP) in two editions for (a) small and medium enterprises and (b) large corporations, respectively. Its game design is inspired by Dungeons & Dragons role-playing games and facilitates LEGO models of the in-game target organizations. Participants switch roles by playing a group of SE penetration testers and conducting a security audit guided by the game master. We evaluated the created game with different student groups, achieving highly immersive and flexible training, resulting in an entertaining way of learning about SE and raising awareness.

description: Il tema della trasformazione digitale dei sistemi di istruzione compare fra le priorità strategiche dell’Unione europea (UE) da oltre un ventennio, rappresentando tanto un’opportunità di crescita e sviluppo, quanto una sfida internazionale per raggiungere la necessaria indipendenza tecnologica. Con la crisi pandemica del 2020, i sistemi di istruzione europei sono stati messi di fronte all’urgenza di adeguare infrastrutture e competenze ad un nuovo ecosistema digitale. Infatti, nonostante l’istruzione terziaria si sia dimostrata più resiliente di altri livelli di istruzione nell’affrontare il cambiamento, e nonostante la consapevolezza ed i richiami all’importanza strategica di dotarsi delle necessarie infrastrutture e competenze, l’emergenza sanitaria ha trovato impreparati la maggior parte degli stati membri e delle istituzioni formative in Europa.

PRESENCE OF PERFLUOROALKYL SUBSTANCES, METALS, AND IONS IN LANDFILL-ADJACENT SURFACE WATERS: CASE STUDIES IN ORANGE COUNTY AND SAMPSON COUNTY, NORTH CAROLINA
Creators: name: Walsh, Aleah

description: Landfills threaten water quality if leachate/runoff enters surface/groundwater, presenting the need for reliable environmental indicators. Landfills are identified sources of perfluoroalkyl substances (PFAS) into the environment. This study is the first to characterize PFAS, metals, and ions in surface waters (SW) adjacent to landfills and evaluate co-occurrence to infer anthropogenic influence. Case study landfills are located in Sampson County (SC) and Orange County (OC).  In SW proximal to the SC landfill, we observed elevated concentrations of legacy PFAS (historically measured) and novel PFAS (recently discovered in association with a fluoroproduct company). Correlation between metals/ions and PFAS may suggest that metals/ions are attributable to the landfill. In SC, Vanadium, selenium, sodium, and bromide concentrations correlated well with PFAS levels. In OC, legacy, but not novel, PFAS were elevated near the landfill. Cobalt, selenium, magnesium, and calcium showed correlation with PFAS. These findings demonstrate the need for more comprehensive monitoring near landfills.

description: The radio frequency 1.4 GHz transition of the atomic hydrogen is one of the important tracers of the diffuse neutral interstellar medium. Radio astronomical observations of this transition, using either a single dish telescope or an array interferometer, reveal different properties of the interstellar medium. Such observations are particularly useful to study the multiphase nature and turbulence in the interstellar gas. Observations with multiple radio telescopes have recently been used to study these two closely related aspects in greater detail. Using various observational techniques, the density and the velocity fluctuations in the Galactic interstellar medium was found to have a Kolmogorov-like power law power spectra. The observed power law scaling of the turbulent velocity dispersion with the length scale can be used to derive the true temperature distribution of the medium. Observations from a large ongoing atomic hydrogen absorption line survey have also been used to study the distribution of gas at different temperature. The thermal steady state model predicts that the multiphase neutral gas will exist in cold and warm phase with temperature below 200 K and above 5000 K respectively. However, these observations clearly show the presence of a large fraction of gas in the intermediate unstable phase. These results raise serious doubt about the validity of the standard model, and highlight the necessity of alternative theoretical models. Interestingly, numerical simulations suggest that some of the observational results can be explained consistently by including the effects of turbulence in the models of the multiphase medium. This review article presents a brief outline of some of the basic ideas of radio astronomical observations and data analysis, summarizes the results from recent observations, and discusses possible implications of the results.

description: The General Data Protection Regulation (GDPR) was implemented in 2018 to strengthen and harmonize the data protection of individuals within the European Union. One key aspect is Article 15, which gives individuals the right to access their personal data in an understandable format. Organizations offering services to Europeans had five years' time to optimize their processes and functions to comply with Article 15. This study aims to explore the process of submitting and receiving the responses of organizations to GDPR Article 15 requests. A quantitative analysis obtains data from various websites to understand the level of conformity, the data received, and the challenges faced by individuals who request their data. The study differentiates organizations operating worldwide and in Germany, browser website- and app-based usage, and different types of websites. Thereby, we conclude that some websites still compile the data manually, resulting in longer waiting times. A few exceptions did not respond with any data or deliver machine-readable data (GDRP Article 20). The findings of the study additionally reveal ten patterns individuals face when requesting and accessing their data.

description: We construct minimum effective models to investigate the pairing symmetry in the newly discovered quasi-one-dimensional superconductor K$_2$Cr$_3$As$_3$. We show that a minimum three-band model based on the $d_{z^2}$, $d_{xy}$ and $d_{x^2-y^2}$ orbitals of one Cr sublattice can capture the band structures near Fermi surfaces. In both weak and strong coupling limits, the standard random phase approximation (RPA) and mean-field solutions consistently yield the triplet $p_z$-wave pairing as the leading pairing symmetry for physically realistic parameters. The triplet pairing is driven by the ferromagnetic fluctuations within the sublattice. The gap function of the pairing state possesses line gap nodes on the $k_z=0$ plane on the Fermi surfaces.

Il sentimentalismo nel teatro russo di inizio ‘800: ascesa e caduta di Vladislav Ozerov
Creators: name: Venniro, Laura
Publisher: name: Humanities
Year: 2023

description: In Russia il sentimentalismo aveva trovato la sua veste letteraria in un primo tempo nel romanzo e poi nella novella, che divenne lo strumento di espressione più adatto per svelare l’universo intimo delle persone comuni. Vladislav Ozerov operò una rivoluzione letteraria portando sulle scene teatrali l’attenzione sulla complessità e contraddittorietà dei sentimenti umani. Ozerov riuscì a ritrarre il mondo delle emozioni, il profondo groviglio del cuore, tutto quel patrimonio interiore in cui ogni essere umano poteva identificarsi. L’entusiasmo del pubblico era anche suscitato dalle trame, tratte dagli episodi più noti della storia russa: era un entusiasmo che si tingeva di acceso patriottismo in un’epoca in cui la Russia era in guerra contro la Francia napoleonica.

description: Phishing is a major cyber threat to organizations that can cause financial and reputational damage, threatening their existence. The technical measures against phishing should be complemented by awareness training for employees. However, there is little validation of awareness measures. Consequently, organizations have an additional burden when integrating awareness training, as there is no consensus on which method brings the best success. This paper examines how awareness concepts can be successfully implemented and validated. For this purpose, various factors, such as requirements and possible combinations of methods, are taken into account in our case study at a small- and medium-sized enterprise (SME). To measure success, phishing exercises are conducted. The study suggests that pleasant campaigns result in better performance in the simulated phishing exercise. In addition, significant improvements and differences in the target groups could be observed. The implementation of awareness training with integrated key performance indicators can be used as a basis for other organizations.

description: The Stark shift due to blackbody radiation (BBR) is the key factor limiting the performance of many atomic frequency standards, with the BBR environment inside the clock apparatus being difficult to characterize at a high level of precision. Here we demonstrate an in-vacuum radiation shield that furnishes a uniform, well-characterized BBR environment for the atoms in an ytterbium optical lattice clock. Operated at room temperature, this shield enables specification of the BBR environment to a corresponding fractional clock uncertainty contribution of $5.5 \times 10^{-19}$. Combined with uncertainty in the atomic response, the total uncertainty of the BBR Stark shift is now $1\times10^{-18}$. Further operation of the shield at elevated temperatures enables a direct measure of the BBR shift temperature dependence and demonstrates consistency between our evaluated BBR environment and the expected atomic response.

The Financial Impact of Co-Locating Agricultural Production  and Solar Power Generation
Creators: name: Cuppari, Rosa Isabella
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Farms across the US have been consolidating in the face of shrinking margins while experiencing increasing competition for land use. The co-location of solar power production and agriculture, known as agrivoltaic systems, may be an effective compromise, as it can both supplement farmers’ incomes and stabilize revenues.      A model is developed to stochastically generate weather variables and commodity prices to conduct an analysis comparing net revenues for a solar only plot, a farm only plot, and an AVS plot.  In the case studies considered (Oregon/North Carolina, alfalfa/soybeans/strawberries), co-location substantially increases farmers’ annual net revenues (~250-5,500%). In the case of more financially variable crops (e.g., strawberries), co-location can reduce variability and improve 5th percentile net revenues by 49-55%. Compared to federal crop insurance, co-location provides larger revenue support but smaller risk management benefits. Regardless, co-location shows promise in benefiting farmers’ net revenues while also contributing to a low carbon future.

description: Acquired brain injury (ABI) can be a life changing condition, affecting housing, independence, and employment. Machine learning (ML) is increasingly used as a method to predict ABI outcomes, however improper model evaluation poses a potential bias to initially promising findings (Chapter One). This study aimed to evaluate, with transparent reporting, three common ML classification methods. Regularised logistic regression with elastic net, random forest and linear kernel support vector machine were compared with unregularised logistic regression to predict good psychosocial outcomes after discharge from ABI inpatient neurorehabilitation using routine cognitive, psychometric and clinical admission assessments. Outcomes were selected on the basis of decision making for care packages: accommodation status, functional participation, supervision needs, occupation and quality of life. The primary outcome was accommodation (n = 164), with models internally validated using repeated nested cross-validation. Random forest was statistically superior to logistic regression for every outcome with areas under the receiver operating characteristic curve (AUC) ranging from 0.81 (95% confidence interval 0.77-0.85) for the primary outcome of accommodation, to its lowest performance for predicting occupation status with an AUC of 0.72 (0.69-0.76). The worst performing ML algorithm was support vector machine, only having statistically superior performance to logistic regression for one outcome, supervision needs, with an AUC of 0.75 (0.71-0.80). Unregularised logistic regression models were poorly calibrated compared to ML indicating severe overfitting, unlikely to perform well in new samples. Overall, ML can predict psychosocial outcomes using routine psychosocial admission data better than other statistical methods typically used by psychologists.

description: Increased production costs associated with an increase in the cost of feedstuffs has made animal health and production efficiency an ever more essential part of the feedlot beef industry. Compared with other feedlot health concerns, lameness has not been widely investigated but has been reported to account for 16% of all feedlot health problems. Costs associated with lame feedlot cattle include the cost of treatment, death loss, and loss due to chronic animals or realizer sale. Lameness, specifically footrot, is a cause of poor performance in feedlot cattle. The potential impact of lameness on cattle comfort and overall welfare, along with health and performance, warrants research to better understand the causes and pathogenesis of lameness.

description: This case study of one Nova Scotian school examined teachers' experiences with undertaking a literacy change initiative. Interviews and focus groups with 15 teachers revealed that teachers' initial participation in the initiative stemmed from collecting student data that demonstrated students were struggling with decoding and a lack of systematic phonics instruction. The teachers discussed challenges they faced as a result of shifting their practice and the need for further professional development and collaboration. The findings of this case study have implications for other schools seeking to implement changes to teaching practices, and achievement outcomes, and highlight the importance of supporting teachers in providing time and resources to collectively put in place instructional strategies that are aligned with students' educational goals.

description: We report the observation of band gaps for low loss exciton-polaritons propagating outside the light cone in GaAs-based planar waveguides patterned into two-dimensional photonic crystals. By etching square lattice arrays of shallow holes into the uppermost layer of our structure, we open gaps on the order of 10 meV in the photonic mode dispersion, whose size and light-matter composition can be tuned by proximity to the strongly coupled exciton resonance. We demonstrate gaps ranging from almost fully photonic to highly excitonic. Opening a gap in the exciton-dominated part of the polariton spectrum is a promising first step towards the realization of quantum-Hall-like states arising from topologically nontrivial hybridization of excitons and photons.

Year: 2015
Subjects: subject: Mathematical Physics (math-ph)

description: We study the singular values of the product of two coupled rectangular random matrices as a determinantal point process. Each of the two factors is given by a parameter dependent linear combination of two independent, complex Gaussian random matrices, which is equivalent to a coupling of the two factors via an Itzykson-Zuber term. We prove that the squared singular values of such a product form a biorthogonal ensemble and establish its exact solvability. The parameter dependence allows us to interpolate between the singular value statistics of the Laguerre ensemble and that of the product of two independent complex Ginibre ensembles which are both known. We give exact formulae for the correlation kernel in terms of a complex double contour integral, suitable for the subsequent asymptotic analysis. In particular, we derive a Christoffel-Darboux type formula for the correlation kernel, based on a five term recurrence relation for our biorthogonal functions. It enables us to find its scaling limit at the origin representing a hard edge. The resulting limiting kernel coincides with the universal Meijer G-kernel found by several authors in different ensembles. We show that the central limit theorem holds for the linear statistics of the singular values and give the limiting variance explicitly.

Com esse trabalho, proponho analisar como essa experiência me impactou, durante o período de minha formação como arquiteta e urbanista, e como se reflete na identidade dos estudantes, moldando suas perspectivas e práticas profissionais. Dentre os elementos que conformam a experiência de vivenciar o centro histórico, destaco aspectos materiais, observados na preservação do patrimônio cultural, e imateriais, traduzidos nas relações afetivas com o lugar. Nesse contexto, a formação para o curso de arquitetura e urbanismo é embasada pela integração entre teoria e prática em diferentes formas de experimentação e prospecção. Desenvolvo esse estudo no âmbito da formação no Mestrado Profissional do Programa de Pós-graduação em Projeto e Patrimônio da FAU-UFRJ, iniciado em 2022. No Mestrado intenciono desenvolver uma proposta de requalificação dos espaços livres do Complexo Trapiche Santo Ângelo, dentro na temática de espaços livres, intra e extra quadras. Enfatizo a importância para o meu trabalho na compreensão de como a imersão e a vivência no ambiente do centro histórico enriquecem a nossa formação como profissionais, ao promover uma abordagem mais sensível e afetiva em relação à história e ao ambiente urbano característico desse setor da cidade de São Luís. Esse trabalho intenciona uma compreensão mais ampla, e fundamentada em vivências pessoais, sobre a relação entre memória coletiva e identidade destes arquitetos e urbanistas e dos estudantes, formados e em formação na FAU/UEMA.

description: The article addresses authenticity and aestheticization in a context of coffee culture and branding. Coffee culture exemplifies an area with an increased focus on authenticity. Knowledge about origin, cultivation methods, processing, and type of coffee have become important dimensions in evaluating the authentic coffee experience and taste of coffee. At the same time, coffee brands strive to present unique and authentic coffee identities. Based on a textual/aesthetic analysis of a sample of images on Nespresso’s Danish website, the article examines the role of aestheticization in branding coffee as authentic. The article demonstrates the social semiotic concept of modality as a perspective to understand the ways in which authenticity and aestheticization are connected.

The Use of a Mouse Model to Determine the Influence of Diet and Genetics on Vitamin D Status, Vitamin D Deficiency, and Glycemic Control

description: Well-known for its importance in calcium homeostasis, there is evidence that vitamin D also plays a role in the maintenance of glycemic control. In this study, we utilized a panel of Collaborative Cross inbred mice to investigate the extent to which vitamin D status, vitamin D deficiency, and glycemic regulation are influenced by diet and genetic background. We detected a dietary treatment effect on 25(OH)D but not on 1,25(OH)2D. We detected genetic effects on vitamin D status, deficiency, and on glycemic control. Interestingly, strains with lower vitamin D had lower markers of glycemic control. Lastly, dietary depletion of vitamin D led to lower liver GAPDH expression, which was also associated with lower markers of glycemic control. These data not only validate a relationship between vitamin D status and glycemic regulation, but provide evidence that genetic contribution to that status is an important factor in understanding risk of associated physiological outcomes.

The PadR-like transcriptional regulator LftR ensures efficient invasion of Listeria monocytogenes into human host cells

description: Invasion of the bacterial pathogen Listeria monocytogenes into human host cells requires specialized surface molecules for attachment and induction of phagocytosis. However, efficient invasion is also dependent on factors with house-keeping functions, such as SecA2-dependent secretion of autolysins for post-divisional segregation of daughter cells. Mutations in this pathway prevent degradation of peptidoglycan cross-walls, so that long cell chains are formed that cannot be phagocytosed. The extreme chaining of such mutants manifests as rough colony phenotype. One rough clone was isolated from a transposon library with a transposon insertion in the uncharacterized lmo0720 gene (lftS) together with a spontaneous point mutation in the secA2 gene. We separated both mutations and demonstrated that this point mutation in the intramolecular regulator 2 domain of SecA2 was sufficient to inactivate the protein. In contrast, lftS deletion did not cause a ΔsecA2-like phenotype. lftS is located in an operon with lftR (lmo0719), encoding a PadR-like transcriptional regulator, and lftR deletion affected growth, invasion and day-light dependent coordination of swarming. Inactivation of lftS partially suppressed these phenotypes, suggesting a functional relationship between LftR and LftS. However, the invasion defect of the ΔlftR mutant was only marginally suppressed by lftS removal. LftR regulates expression of the lmo0979–0980 (lieAB) operon, encoding a putative multidrug resistance transporter and lieAB transcription was strongly upregulated in the absence of LftR. Deletion of lieAB in the ΔlftR background restores wild type-like invasion levels. Hence, we conclude that tight transcriptional repression of the lieAB operon is essential for efficient listerial host cell invasion.
Ensemble of Counterfactual Explainers

description: In eXplainable Artificial Intelligence (XAI), several counterfactual explainers have been proposed, each focusing on some desirable properties of counterfactual instances: minimality, actionability, stability, diversity, plausibility, discriminative power. We propose an ensemble of counterfactual explainers that boosts weak explainers, which provide only a subset of such properties, to a powerful method covering all of them. The ensemble runs weak explainers on a sample of instances and of features, and it combines their results by exploiting a diversity-driven selection function. The method is model-agnostic and, through a wrapping approach based on autoencoders, it is also data-agnostic.

description: We measure the location and evolutionary vectors of 69 Herschel-detected broad-line active galactic nuclei (BLAGNs) in the M_BH-M_* plane. BLAGNs are selected from the COSMOS and CDF-S fields, and span the redshift range 0.2< z<2.1. Black-hole masses are calculated using archival spectroscopy and single-epoch virial mass estimators, and galaxy total stellar masses are calculated by fitting the spectral energy distribution (subtracting the BLAGN component). The mass-growth rates of both the black hole and galaxy are calculated using Chandra/XMM-Newton X-ray and Herschel far-infrared data, reliable measures of the BLAGN accretion and galaxy star formation rates, respectively. We use Monte Carlo simulations to account for biases in our sample, due to both selection limits and the steep slope of the massive end of the galaxy stellar-mass distribution. We find our sample is consistent with no evolution in the M_BH-M_* relation from z~2 to z~0. BLAGNs and their host galaxies which lie off the black hole mass galaxy total stellar mass relation tend to have evolutionary vectors anti-correlated with their mass ratios: that is, galaxies with over-massive (under-massive) black holes tend to have a low (high) ratio of the specific accretion rate to the specific star formation rate. We also use the measured growth rates to estimate the preferred AGN duty cycle for our galaxies to evolve most consistently onto the local M_BH-M_Bul relation. Under reasonable assumptions of exponentially declining star formation histories, the data suggest a non-evolving (no more than a factor of a few) BLAGN duty cycle among star-forming galaxies of 10% (1sigma range of 1-42% at z<1 and 2-34% at z>1).

description: This paper presents a novel method to recognize stem - calyx of an apple using shape descriptors. The main drawback of existing apple grading techniques is that stem - calyx part of an apple is treated as defects, this leads to poor grading of apples. In order to overcome this drawback, we proposed an approach to recognize stem-calyx and differentiated from true defects based on shape features. Our method comprises of steps such as segmentation of apple using grow-cut method, candidate objects such as stem-calyx and small defects are detected using multi-threshold segmentation. The shape features are extracted from detected objects using Multifractal, Fourier and Radon descriptor and finally stem-calyx regions are recognized and differentiated from true defects using SVM classifier. The proposed algorithm is evaluated using experiments conducted on apple image dataset and results exhibit considerable improvement in recognition of stem-calyx region compared to other techniques.

Symmetry protected topological phases in spin-1 ladders and their phase transitions

description: We study two-legged spin-1 ladder systems with $D_2\times σ$ symmetry group, where $D_2$ is discrete spin rotational symmetry and $σ$ means interchain reflection symmetry. The system has one trivial phase and seven nontrivial symmetry protected topological (SPT) phases. We construct Hamiltonians to realize all of these SPT phases and study the phase transitions between them. Our numerical results indicate that there is no direct continuous transition between any two SPT phases we studied. We interpret our results via topological nonlinear sigma model effective field theory, and further conjecture that generally there is no direct continuous transition between two SPT phases in one dimension if the symmetry group is discrete at all length scales.
