description: We study the production of massive fermions in arbitrary vector and axial-vector classical backgrounds using effective action techniques. A perturbative calculation shows the different features of each field and in particular it is seen that pure temporal axial fields can produce particles whereas it is not possible for a pure vector background. We also analyze from a non-perturbative point of view a particular configuration with constant electric and axial fields and show that the presence of the axial background inhibits the production from the electric field.

description: In this paper, we introduce BINet, a neural network architecture for real-time multi-perspective anomaly detection in business process event logs. BINet is designed to handle both the control flow and the data perspective of a business process. Additionally, we propose a set of heuristics for setting the threshold of an anomaly detection algorithm automatically. We demonstrate that BINet can be used to detect anomalies in event logs not only on a case level but also on event attribute level. Finally, we demonstrate that a simple set of rules can be used to utilize the output of BINet for anomaly classification. We compare BINet to eight other state-of-the-art anomaly detection algorithms and evaluate their performance on an elaborate data corpus of 29 synthetic and 15 real-life event logs. BINet outperforms all other methods both on the synthetic as well as on the real-life datasets.

description: Top like vector quarks arising from underlying strong sectors are expected to have large decay widths pushing them beyond the narrow width approximation. In this paper we consider a broad colored vector quark that strongly couples to an exotic pseudoscalar. We use the full 1PI resummed propagator for the exotic quark to recast the present LHC constraints ruling out masses below $\sim1.2~(1.1)$ TeV for width to mass ratio of $0.1~(0.6)$. We utilize machine learning techniques that are demonstratively more efficient than traditional cut based searches to present the reach of HL-LHC on the parameter space of this broad resonance. We find that at $3~ab^{-1}$ the HL-LHC has a discovery potential up to $1.6$ TeV dominated by the pair production channel. We study the feasibility of using machine learning techniques to analyze the broad resonance peaks expected from these exotic quarks at collider experiments like the LHC.

description: Ever since the 1880s, India has had a thriving and robust media. Television, radio, cinema, newspapers, magazines, and Internet-based Websites/portals are among the several sorts of mass media communications in India. However, according to the Press Freedom Index, India scored 142nd out of 180 nations in 2020, which is said to be attributed to Prime Minister Narendra Modi's Bharatiya Janata Party and its Hindutva adherents imposing increased influence over the media. Even as its sympathizers threaten outlets and particular reporters, the government has initiated punitive charges against media that contradict its judgments. In addition, according to a study released in 2021 by Freedom House, intimidation of journalists intensified under Modi's leadership.

description: Thermophysical Models (TPMs), which have proven to be a powerful tool in the interpretation of the infrared emission of asteroid surfaces, typically make use of a priori obtained shape models and spin axes for use as input boundary conditions. We test then employ a TPM approach - under an assumption of an ellipsoidal shape - that exploits the combination of thermal multi-wavelength observations obtained at pre- and post-opposition. Thermal infrared data, when available, at these observing circumstances are inherently advantageous in constraining thermal inertia and sense of spin, among other physical traits. We show that, despite the lack of a priori knowledge mentioned above, the size, albedo, and thermal inertia of an object are well-constrained with precision comparable to that of previous techniques. Useful estimates of the surface roughness, shape, and spin direction can also be made, to varying degrees of success. Applying the method to WISE observations, we present best-fit size, albedo, thermal inertia, surface roughness, shape elongation and sense of spin direction for 21 asteroids. We explore the thermal inertia's correlation with diameter, after accounting for its dependance on heliocentric distance.

Emphasis will be given to some methods applied in the analysis and characterization of diffusive regimes through the memory function, the mixing condition (or irreversibility), and ergodicity. Those methods can be used in the study of small-scale systems, ranging in size from single-molecule to particle clusters and including among others polymers, proteins, ion channels and biological cells, whose diffusive properties have received much attention lately.

Conscience in Toddlerhood : The Link Between Guilt and Helping

description: Experiencing guilt versus shame is linked to reparative prosociality in toddlerhood (e.g. Drummond et al., 2017; Kolak & Volling, 2022); but, how a tendency to experience guilt or shame relates to other empathic and altruistic behaviours among toddlers remains relatively unknown. Here, we evaluate whether 29-month-olds’ (n=48, Mage=30.23 months, SD=0.64) guilt- or shame-proneness (after breaking a toy; Barrett et al., 1993) is concurrently associated with comforting an ‘injured’ researcher (Zahn-Waxler et al., 1992) and sharing valuable belongings (Newton et al., 2016). Concurrent analyses unveiled that toddlers who exhibited guilt did not have higher comforting (t(44.36)=0.14, p =.89) or sharing (t(44.963)=0.23, p=.82) scores than toddlers who exhibited shame, suggesting that experiencing guilt/shame might not play a role in all the prosocial behaviours toddlers produce.

description: Empirische Analysen zur Arbeitsteilung im Haushalt zeigen wiederholt, dass in heterosexuellen Partnerschaften die Geschlechtervariable eine bedeutende Rolle spielt: Frauen übernehmen einen größeren Anteil als Männer, und die einzelnen Tätigkeitsbereiche sind geschlechtertypisch assoziiert. Insbesondere Routinetätigkeiten wie das Wäschewaschen oder das Staubsaugen werden häufiger von Frauen erledigt. Trotzdem zeigt sich auch in schwulen und lesbischen Partnerschaften die Tendenz, dass Routinetätigkeiten häufiger von ausschließlich einer Person erledigt werden – wobei die Geschlechterbinarität naturgemäß keine Rolle spielen kann. Welche Faktoren also können diese Ein-Personen-Spezialisierung erklären? Dazu wurden Daten des Generations and Gender Programme (GGP) der GGP-II Welle analysiert. Um eine genügend große Stichprobe gleichgeschlechtlicher Paare zur Verfügung zu haben, wurde eine "internationale" Gruppe aggregiert (Österreich, Dänemark, Norwegen, Estland, Tschechien und Moldau). Es zeigt sich: Wie bei heterosexuellen Paaren spielen auch hier Kinder, Einkommen, Bildung und Dauer des Zusammenwohnens eine Rolle – jedoch auf einem statistisch nicht signifikanten Level.

description: The description of relativistic effects requires a preliminary definition of events localised in space-time while the clocks used for time definition and the fields used in synchronisation or localisation procedures are necessarily quantum systems. We outline an algebraic framework where basic requirements of quantum theory and relativity are consistently dealt with. This approach which may be termed as a `quantum relativity' is built on the algebra of symmetries. It contains the definition of quantum observables associated with Einstein localisation in space-time as well as the evaluation of their commutation relations including the energy-time relation. These commutators also describe the relativistic shifts undergone under frame transformations, not only for inertial frames but also for uniformly accelerated frames. The quantum redshift laws differ from their classical counterparts while still obeying universal metric properties. The paper presents this approach in terms closely connected to the seminal Einstein conception of localisation in space-time and refers to already published papers for more technical developments.

description: We use the machine learning technique to search the polytope which can result in an orientifold Calabi-Yau hypersurface and the "naive Type IIB string vacua". We show that neural networks can be trained to give a high accuracy for classifying the orientifold property and vacua based on the newly generated orientifold Calabi-Yau database with $h^{1,1}(X) \leq 6$ arXiv:2111.03078. This indicates the orientifold symmetry may already be encoded in the polytope structure. In the end, we try to use the trained neural networks model to go beyond the database and predict the orientifold signal of polytope for higher $h^{1,1}(X)$.

title: A New Method for Estimating the Physical Characteristics of Martian Dust Devils
Creators: name: Mann, Shelly Cahoon
Publisher: name: Old Dominion University Libraries
Year: 2021

description: Critical to the future exploration of Mars is having a detailed understanding of the atmospheric environment and its potential dangers. The dust devil is one of these potential dangers. The transport of dust through saltation is believed to be the driving mechanism responsible for Martian weather patterns. The two primary mechanisms for dust transport are dust storms and dust devils. Dust devils on Mars are a frequent occurrence with one in five so called giant dust devils being large enough to leave scars on the surface that are visible from space. Due to the thin atmosphere, winds of 60 mph would feel more like 6 mph terrestrial winds; however, the saltation of dust particles could pose a threat to structures and equipment. Materials for permanent structures and equipment will need to be abrasion resistant, and the possible solenoidal effects of the columnar vortices, such as triboelectric charging and induced magnetic fields, will need to be well understood. Thus, it would be useful to have a method of quantifying the physical properties of Martian dust devils.

This work has endeavored to provide such a method by employing an improved Rankine vortex model developed by Ash, Zardadkhan, and Zuckerwar (2011, 2013) which agreed well with terrestrial field measurements. Atmospheric differences between Earth and Mars are profound and limited or incomplete in situ data for Martian dust devil events presented a challenge when applying the Ash-Zardadkhan-Zuckerwar method; however, through an inclusive representation of the atmosphere, its thermodynamic properties, and proven scientific inferences of other necessary atmospheric properties, this work has developed a useful tool to aid in the safe advancement of large-scale planetary exploration.

The classical example of the doped Mott-insulator La_{1-x}Sr_xTiO_3 was studied by the new method and the results showed qualitative improvement in agreement with experimental photoemission spectra.

We show, first for a class of two-fluid solutions and then for the general multifluid case, that the closed universe will obey the holographic principle if it also contains matter with w < - 1/3, and if the present value of its total density is sufficiently close to the critical density. It is possible that such matter can be realised by some form of `quintessence', much studied recently.

description: We present a hybrid classical/quantum algorithm for efficiently solving the eigenvalue problem of many-particle Hamiltonians on quantum computers with limited resources by splitting the workload between classical and quantum processors. This algorithm reduces the needed number of qubits at the expense of an increased number of quantum evaluations. We demonstrate the method for the Hubbard model and show how the conservation of the z-component of the total spin allows the spin-up and spin-down configurations to be computed on classical and quantum hardware, respectively. Other symmetries can be exploited in a similar manner.

Chemoselective conjugation strategies for the programmable detection of epigenetic cytosine 5-modifications with transcription activator-like effectors

description: Methylation at the cytosine (C) carbon-5 position in DNA is a reversible regulatory element of transcription in mammalian cells involved in development and disease. An active demethylation pathway through iterative oxidation of 5-methylcytosine (5mC) has been identified that leads to abasic sites at which unmodified C are restored via the base excision repair (BER) pathway. This process yields 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC) as partially stable intermediates. An increasing amount of data indicate that these 5-modified cytosines can also act as epigenetic regulatory elements and are involved in developmental and pathological processes. However, the function of epigenetic 5-modified cytosines are not fully understood and require sensitive typing and profiling approaches with high resolution. Engineered transcription activator-like effector (TALE) proteins have been established as programmable DNA-binders for the detection of epigenetic 5-modified cytosines. However, previous efforts to engineer new TALE selectivities did either not provide full selectivity for epigenetic 5-modified cytosines or had low affinity to target DNA. To overcome these hurdles, two novel TALE-based strategies based on chemical conjugation reactions were developed. In the first approach, a size-reduced TALE repeat with universal binding to the four canonical nucleobases and four epigenetic 5-modified cytosines was engineered. Chemoselective conjugation of 5hmC, 5fC or 5caC to dedicated blocking groups was found to abolish TALE binding. This enabled complete decoding of the three oxidized 5mC derivatives (ox5mCs) at single positions within target DNA. In the second approach, the non-canonical amino acid (ncAA) para-acetylphenylalanine (pAcF) was incorporated into dedicated positions of the universal TALE repeat. TALEs bearing pAcF maintained universal binding to cytosine 5-modified nucleobases. Furthermore, pAcF-bearing TALE repeats and 5fC-bearing target DNA could be crosslinked through oxime condensation via bifunctional hydroxylamine linkers. This enabled robust and selective enrichment of 5fC-bearing target DNA from genomic DNA (gDNA) backgrounds. Taken together, the addition of selective conjugation chemistries to TALE-based detection methods expand the toolbox for the selective, programmable analysis of epigenetic 5-modified cytosines.
title: The Experience of Joe: A Sociocultural Study of an Autistic Pupil in a Mainstream Secondary School.
Creators: name: Willis, Angela Dawn
Publisher: name: The Open University
Year: 2021

description: This study investigated the experience of Joe, a year nine pupil with autism, as he participated in lessons alongside his peers in a mainstream school. Data were produced by observation of the activity and relationships in five lessons, over two visits, and follow-up interviews with relevant teachers and teaching assistants. Data were analysed using the framework of the institutional, interpersonal, and intrapersonal planes developed by Rogoff (2003). The analysis revealed the dominance of institutional policies, practices, and routines on how Joe was responded to in his lessons. Review of the school policy documentation established that pupils’ reading age scores determined class groupings and, in turn, teachers’ assumptions about the ability range of pupils in their lessons. Special Educational Needs and Disability emerged as a specialist domain within the school with teaching assistants deployed to work with pupils with Education Health and Care Plans in lessons. The teachers and teaching assistants participating in the study seemed tacitly to accept an interactional worldview of schooling (Rogoff, 2016) and to conceptualise learning within the associated cognitive-developmental paradigm. The result of this was that Joe was perceived as ‘just one of the class’. This did not require his teachers to implement the specific strategies that were recommended for him in the school’s SEND register. Rather, teaching assistants mediated curriculum information for him. Uniform transmission teaching approaches meant Joe’s interaction, communication and information processing needs were ignored as the focus was on maximising literacy and curriculum knowledge. The evidence of my study challenges the interactional worldview of SEND. The dominance and acceptance of this worldview limited the opportunities available for teachers and TAs to respond to Joe’s autism as teachers felt constrained by their obligations to report on pupil progress and performance. When a participatory approach was used by a teaching assistant, Joe was able to demonstrate his ability to cooperate, coordinate and contribute to learning activity with others. The approaches occasioned by different paradigmatic beliefs had clear implications for Joe’s participation, how he felt about his contribution to learning and how teachers and TAs described his abilities. The transactional worldview of learning conceptualised within a participatory approach (Rogoff, 2016, p.182) which transformed Joe’s participation offers an insight into ‘inclusion’ that warrants further investigation for the benefits it may offer leaders and teachers in responding to neurodiversity in schools.

description: A treatment of frictional Coulomb drag between two 2-dimensional electron layers in a strong perpendicular magnetic field, within the independent electron picture, is presented. Assuming fully resolved Landau levels, the linear response theory expression for the transresistivity $ρ_{21}$ is evaluated using diagrammatic techniques. The transresistivity is given by an integral over energy and momentum transfer weighted by the product of the screened interlayer interaction and the phase-space for scattering events. We demonstrate, by a numerical analysis of the transresistivity, that for well-resolved Landau levels the interplay between these two factors leads to characteristic features in both the magnetic field- and the temperature dependence of $ρ_{21}$. Numerical results are compared with recent experiments.

Chronotype has been found to vary across countries, and research finds that within countries a later chronotype is correlated with worse health outcomes. This study examines chronotype’s effect on people’s physical and mental health levels across different countries. We recruited 5128 participants from 20 countries over six continents, with approximately 250 participants in each country. Participants completed the survey in a two-week window before and after the autumn equinox, reporting their chronotypes, mental health levels, physical health levels, and depression levels. We used multilevel modeling to study the effect of chronotype on people’s health outcomes within and between countries. We found that within countries, people with chronotypes that are later than the corresponding country’s average tend to have lower physical and mental health outcomes. However, the analysis of between-country effects did not show any relationship between chronotype and people’s health outcomes. Our study’s findings highlight the importance of cultural fit in the relationship between chronotype and health level, demonstrating that people’s chronotypes are most relevant for predicting people’s health in comparison with their own countries’ averages.

Via the off-shell method we find the spectra and eigenvectors of the N-1 independent Gaudin Hamiltonians with symmetry osp(2|1). We also show how the off-shell Gaudin equation solves the trigonometric Knizhnik- Zamolodchikov equation.

title: Local Irishness: storytelling, heritage, and place attachment in Douglastown, Québec.
Creators: name: Leggo, Angelina

description: The community of Douglastown, on the Gaspé Peninsula in eastern Québec, has experienced profound change in recent years. An increase in migration to the area has relegated the once majority Anglophone population to a minority in the region. In response, community members use a history of Irish immigration to the area to differentiate themselves from other places in the Gaspésie and across the province. They likewise use this legacy to strengthen and express place attachment, celebrate their heritage and history, emphasize their language, and continue the traditions of the Catholic Church, both within and outside of their community. Through interviews, participant observation, mapping, and local research, I show how stories in Douglastown revolve around these multiple expressions if Irishness and how this has created a framework for defining belonging in the past that still resonates within the community today.

description: We present a unified derivation of covariant time derivatives, which transform as tensors under a time-dependent coordinate change. Such derivatives are essential for formulating physical laws in a frame-independent manner. Three specific derivatives are described: convective, corotational, and directional. The covariance is made explicit by working in arbitrary time-dependent coordinates, instead of restricting to Eulerian (fixed) or Lagrangian (material) coordinates. The commutator of covariant time and space derivatives is interpreted in terms of a time-curvature that shares many properties of the Riemann curvature tensor, and reflects nontrivial time-dependence of the metric.

description: We experimentally investigate a non-linear Hall effect for three-dimensional WTe$_2$ and Cd$_3$As$_2$ single crystals, representing Weyl and Dirac semimetals, respectively. We observe finite second-harmonic Hall voltage, which depends quadratically on the longitudinal current in zero magnetic field. Despite this observation well corresponds to the theoretical predictions, only magnetic field dependence allows to distinguish the non-linear Hall effect from a thermoelectric response. We demonstrate that second-harmonic Hall voltage shows odd-type dependence on the direction of the magnetic field, which is a strong argument in favor of current-magnetization effects. In contrast, one order of magnitude higher thermopower signal is independent of the magnetic field direction.

description: We consider the X-ray luminosity difference between neutron star and black hole soft X-ray transients (NS and BH SXTs) in quiescence. The current observational data suggest that BH SXTs are significantly fainter than NS SXTs. The luminosities of quiescent BH SXTs are consistent with the predictions of binary evolution models for the mass transfer rate if (1) accretion occurs via an ADAF in these systems and (2) the accreting compact objects have event horizons. The luminosities of quiescent NS SXTs are not consistent with the predictions of ADAF models when combined with binary evolution models, unless most of the mass accreted in the ADAF is prevented from reaching the neutron star surface. We consider the possibility that mass accretion is reduced in quiescent NS SXTs because of an efficient propeller and develop a model of the propeller effect that accounts for the observed luminosities. We argue that modest winds from ADAFs are consistent with the observations while strong winds are probably not.

description: Business model literature has been focused on value co-creation and co-capture logic in understanding business models in the ecosystem. To understand the “Ex Ante” source of ecosystem-based value creation/capture, this paper proposes opportunity complementarity as a key antecedent and construct for the ecosystem-based value creation and capture in data-driven business ecosystems.

description: Mageto, a random number generator based on one-dimensional cellular automaton (CA) is presented. Three procedures of secure implementation using Mageto is proposed and discussed. Implementations are very efficient in a wide range of hardware and software scenarios. It includes the advanced application of the Internet of Things (IoT) and cyber-physical systems which are both needed for computationally-efficient cryptographic primitives. Furthermore, the proposed primitive is inherently resistant against the Side Channel Attack (SCA), where many currently available ciphers, such as AES, require additional hardware or software effort to prevent SCA line of attack.

description: The problem of off-grid direction-of-arrival (DOA) estimation is investigated. We develop a grid-based method to jointly estimate the closest spatial frequency (the sine of DOA) grids, and the gaps between the estimated grids and the corresponding frequencies. By using a second-order Taylor approximation, the data model under the framework of joint-sparse representation is formulated. We point out an important property of the signals of interest in the model, namely the proportionality relationship, which is empirically demonstrated to be useful in the sense that it increases the probability of the mixing matrix satisfying the block restricted isometry property. Simulation examples demonstrate the effectiveness and superiority of the proposed method against several state-of-the-art grid-based approaches.

description: Locking of a laser frequency to an atomic or molecular resonance line is a key technique in applications of laser spectroscopy and atomic metrology. Modulation transfer spectroscopy (MTS) provides an accurate and stable laser locking method which has been widely used. Normally, the frequency of the MTS signal would drift due to Zeeman shift of the atomic levels and rigorous shielding of stray magnetic field around the vapor cell is required for the accuracy and stability of laser locking. Here on the contrary, by applying a transverse bias magnetic field, we report for the first time observation of a magnetic-enhanced MTS signal on the transition of 87Rb D2-line Fg=1 to Fe=0 (close to the repump transition of Fg=1 to Fe=2), with signal to noise ratio larger than 100:1. The error signal is immune to the external magnetic fluctuation. Compared to the ordinary MTS scheme, it provides a robust and accurate laser locking approach with more stable long-term performance. This technique can be conveniently applied in areas of laser frequency stabilization, laser manipulation of atoms and precision measurement.

description: We study an area distance in the Riemannian spacetime with expansion, vorticity and acceleration. It is shown that this observable depends on expansion, deceleration and acceleration parameters to third order in redshift, as well as on vorticity. Thus, the considerable acceleration or vorticity of the Universe can substantially influence the standard astronomical distance calibrators.

description: The spectral functions of tJ and tJ_{XY} models in the limit of J/t-> 0 and at finite temperatures T>>t are calculated using the spin-charge factorized wave function. We find that the Luttinger-liquid like scaling behavior for a finite system with L sites is restricted below temperatures of the order T = J/L. We also observe weight redistribution in the photoemission spectral function in the energy range t, which is much larger than the temperature.
