description: We use the $4-ε$ expansion to search for fixed points corresponding to $2+1$ dimensional $\mathcal{N}$=1 Wess-Zumino models of $N_Φ$ scalar superfields interacting through a cubic superpotential. In the $N_Φ=3$ case, we classify all SUSY fixed points that are perturbatively unitary. In the $N_Φ=4$ and $N_Φ=5$ cases, we focus on fixed points where the scalar superfields form a single irreducible representation of the symmetry group (irreducible fixed points). For $N_Φ=4$ we show that the S5 invariant super Potts model is the only irreducible fixed point where the four scalar superfields are fully interacting. For $N_Φ=5$, we go through all Lie subgroups of O(5) and then use the GAP system for computational discrete algebra to study finite subgroups of O(5) up to order 800. This analysis gives us three fully interacting irreducible fixed points. Of particular interest is a subgroup of O(5) that exhibits O(3)/Z2 symmetry. It turns out this fixed point can be generalized to a new family of models, with $N_Φ=\frac{\rm N(N-1)}{2}-1$ and O(N)/Z2 symmetry, that exists for arbitrary integer N$\geq3$.

Publisher: name: IEEE
Year: 2021

In this paper, a focus is on the derivation of Thévenin-based models that only require characterization at the converter terminals.
Modeling the unintended common- and differential-mode (CM and DM) behavior of multi-converter power electronic-based systems can be a challenge. Chief among the issues is the need for detailed knowledge of the converter hardware to determine model parameters. In this paper, a focus is on the derivation of Thévenin-based models that only require characterization at the converter terminals. Periodic linear time varying system analysis is first used to derive and consider the applicability such models. Subsequently, methods to experimentally characterize Thévenin parameters are established. The modeling approach is then used to establish worst-case predictions of CM/DM behavior of a microgrid which is validated using both time-domain simulation and hardware experiment.

description: We demonstrate a method for precision spectroscopy on trapped ions in the limit of unresolved motional sidebands. By sympathetic cooling of a chain of crystallized ions we suppress adverse temperature variations induced by the spectroscopy laser that usually lead to a distorted line profle and obtain a Voigt profile with negligible distortions. We applied the method to measure the absolute frequency of the astrophysically relevant D2 transition in single 24-Mg+ ions and find 1072082934.33(16)MHz, a nearly 400fold improvement over previous results. Further, we find the excited state lifetime to be 3.84(10) ns.

To optimize the smart switch operation and distributed energy resource output power, a planned islanding algorithm is designed to minimize the battery energy storage systems' power difference before and after a planned islanding.
Planned islanding is one of the fundamental functions of microgrid (MG) controllers. However, existing planned islanding functions cannot be directly utilized in MGs that have the capability to have both dynamic boundary and multiple sub-MGs. To optimize the smart switch operation and distributed energy resource (DER) output power, a planned islanding algorithm is designed to minimize the battery energy storage systems' power difference before and after a planned islanding. To verify the performance of the proposed algorithm, a hardware-in-the-loop (HIL) test has been conducted by implementing the algorithm in a general purpose MG controller system. The results demonstrate that the difference in active power before and after the planned islanding decreases significantly with the proposed algorithm.
Hadrons in Nuclei: Experiments and Perspectives

description: The question of the origin of hadron masses is one major issue in the understanding of the strong interaction. The challenge is addressed by searching for indications of in-medium modifications of hadron properties and studying hadrons in nuclei. The quest driving in-medium studies is to understand the origin of hadron masses in the context of spontaneous chiral symmetry breaking. The experimental status of the modification of hadron properties in the nuclear medium is discussed including experiments using hadron, heavy-ion, and photon beams. Particular emphasis is put on the production of light mesons from nuclei. A number of experimental programs is underway to provide a detailed comparison of properties of free hadrons and hadrons embedded in nuclei. The existing experimental efforts are discussed and possibilities are introduced for the new WASA-at-COSY facility, initially focussed on investigations of symmetries and symmetry breaking, to contribute to the field.

description: In a 4D chiral Thirring model we analyse the possibility that radiative corrections may produce spontaneous breaking of Lorentz and CPT symmetry. By studying the effective potential, we verified that the chiral current $\barψγ^μ γ_5 ψ$ may assume a nonzero vacuum expectation value which triggers the Lorentz and CPT violations. Furthermore, by making fluctuations on the minimum of the potential we dynamically induce a bumblebee like model containing a Chern-Simons term.

description: The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) started median-resolution spectroscopic (MRS, R$\sim$7500) survey since October 2018. The main scientific goals of MRS, including binary stars, pulsators, and other variable stars are launched with a time-domain spectroscopic survey. However, the systematic errors, including the bias induced from wavelength calibration and the systematic difference between different spectrographs have to be carefully considered during radial velocity measurement. In this work, we provide a technique to correct the systematics in the wavelength calibration based on the relative radial velocity measurements from LAMOST MRS spectra. We show that, for the stars with multi-epoch spectra, the systematic bias which is induced from the exposures of different nights can be well corrected for LAMOST MRS in each spectrograph. And the precision of radial velocity zero-point of multi-epoch time-domain observations reaches below 0.5 km/s . As a by-product, we also give the constant star candidates, which can be the secondary radial-velocity standard star candidates of LAMOST MRS time-domain surveys.

description: The Islamic country estate of ar-Rummānīya is located in the foothills of the Sierra Morena, some 10 km west of the city of Córdoba (Spain). The estate was erected in 965 CE by ad-Durrī “the Little”, a finance minister of the caliph al-Hakam II. The building complex encompasses four terraces, three of which were designed as gardens. On the uppermost terrace stood a series of palatial buildings, including two halls and a large water basin. The aim of the last two seasons of excavation has been the investigation of the garden. Detailed information was gained on the irrigation system and the kinds of plants that grew here. Botanical studies provide evidence for the presence of olive trees, almonds, pomegranate, vine, myrtle and lavender as well as a range of herbs and flowers.

description: We consider a long-range Ising antiferromagnet (LRIAF) put in a transverse field. Applying quantum Monte Carlo method, we study the variation of order parameter (spin correlation in Trotter time direction), susceptibility and average energy of the system for various values of the transverse field at different temperatures. The antiferromagnetic order is seen to get immediately broken as soon as the thermal or quantum fluctuations are added. We also discuss the phase diagram for the Sherrington-Kirkpatrick (SK) model with the same LRIAF bias, also in presence of a transverse field. We find that while the antiferromagnetic order is immediately broken as one adds an infinitesimal transverse field or thermal fluctuation to the system, an infinitesimal SK spin glass disorder is enough to induce a stable glass order in the antiferromagnet. This glass order eventually gets destroyed as the thermal or quantum fluctuations increased beyond their threshold values and the transition to para phase occurs. Indications of this novel phase transition are discussed. Because of the presence of full frustration, this surrogate property of the LRIAF for incubation of stable spin glass phase in it (induced by addition of a small disorder) should enable eventually the study of classical and quantum spin glass phases by using some perturbation theory with respect to the disorder.

description: Accurate detection and classification of online hate is a difficult task. Implicit hate is particularly challenging as such content tends to have unusual syntax, polysemic words, and fewer markers of prejudice (e.g., slurs). This problem is heightened with multimodal content, such as memes (combinations of text and images), as they are often harder to decipher than unimodal content (e.g., text alone). This paper evaluates the role of semantic and multimodal context for detecting implicit and explicit hate. We show that both text- and visual- enrichment improves model performance, with the multimodal model (0.771) outperforming other models' F1 scores (0.544, 0.737, and 0.754). While the unimodal-text context-aware (transformer) model was the most accurate on the subtask of implicit hate detection, the multimodal model outperformed it overall because of a lower propensity towards false positives. We find that all models perform better on content with full annotator agreement and that multimodal models are best at classifying the content where annotators disagree. To conduct these investigations, we undertook high-quality annotation of a sample of 5,000 multimodal entries. Tweets were annotated for primary category, modality, and strategy. We make this corpus, along with the codebook, code, and final model, freely available.

description: The goal of Computer-Aided Instruction (CAI) research is to build instructional programs that incorporate well-prepared course material in lessons that attempt to individualize learning. The role of Artificial Intelligence (Al) is to facilitate a new kind of learning environment that stresses a learner-based paradigm instead of the teacher-based paradigm of traditional CAI. Research in Intelligent Computer-Aided Learning (ICAL) is focused on providing instruction that is sensitive to the student's strengths, weaknesses, and preferred style of learning. In this thesis, research milestones in ICAL are discussed. An Interactive Computer-aided Testing program that seeks to diagnose novices' misconceptions of the assignment statement in Pascal is described. This program was also used to explore the utility of providing explicit models as an aid to learning programming.

description: We address the problem of an unscreened Coulomb charge in graphene, and calculate the local density of states and displaced charge as a function of energy and distance from the impurity. This is done non-perturbatively in two different ways: (1) solving the problem exactly by studying numerically the tight-binding model on the lattice; (2) using the continuum description in terms of the 2D Dirac equation. We show that the Dirac equation, when properly regularized, provides a qualitative and quantitative low energy description of the problem. The lattice solution shows extra features that cannot be described by the Dirac equation, namely bound state formation and strong renormalization of the van Hove singularities.

description: Abstract

Kiran Nagarkar captures the essence of contemporary social reality while also being able to present the realities as critical commentaries. The Indian society is unique in its diversity. The social institution itself is a mash-up of various cultural, religious, and linguistic groups of people. Those people want to live proper life in exacting, still following more than a few decades of freedom. Kiran Nagarkar’s novel Ravan and Eddie, explores the role play of a significant part in addressing the subject of poverty in Mumbai chawls. This research expects to efficiently portray the tragic plights as well as condition of survival of characters. People’s lives in chawls are terrible. The protagonist of this novel Ravan, the son of conventional Hindu parents, and Eddie, the son of Roman Catholic parents, mutiny alongside poverty by means of their actions. They see the world from side to side the lens of understanding, as it appears from the self’s encounter by means of the world outside.

description: In the frame of the Saudi-German collaborative project at Tayma, one of the best preserved pre-Islamic buildings at the oasis of Tayma, known as Qasr al-Radm, was systematically investigated for the first time. Altogether six building phases have been identified. The large rock-cut well may be much older than the main part of the structure, which is probably a 4th/5th century AD construction. By partly dismantling the latter a camel draw was added to it in a time after the visit of Julius Euting to Tayma in 1884, who produced a sketch drawing of the then complete building.

description: The hyperfine interaction between the electron spin and the nuclear spins is one of the main sources of decoherence for spin qubits when the nuclear spins are disordered. An ordering of the latter largely suppresses this source of decoherence. Here we show that such an ordering can occur through a thermodynamic phase transition in two-dimensional (2D) Kondo-lattice type systems. We specifically focus on nuclear spins embedded in a 2D electron gas. The nuclear spins interact with each other through the RKKY interaction, which is carried by the electron gas. We show that a nuclear magnetic order at finite temperature relies on the anomalous behavior of the 2D static electron spin susceptibility due to electron-electron interactions. This provides a connection between low-dimensional magnetism and non-analyticities in interacting 2D electron systems. We discuss the conditions for nuclear magnetism, and show that the associated Curie temperature increases with the electron-electron interactions and may reach up into the millikelvin regime. The further reduction of dimensionality to one dimension is shortly discussed.

description: Contemporary high-resolution sonar systems use broadband pulses and long arrays to achieve high resolution. It is important to understand effects that high-resolution sonar systems might have on quantitative measures of the scattered field due to the seafloor. A quantity called the broadband scattering cross section is defined, appropriate for high-resolution measurements. The dependence of the broadband scattering cross section, $σ_{bb}$ and the scintillation index, $SI$ on resolution was investigated for one-dimensional rough surfaces with power-law spectra and backscattering geometries. Using integral equations and Fourier synthesis, no resolution dependence of $σ_{bb}$ was found. The incoherently-averaged frequency-domain scattering cross section has negligible bandwidth dependence. $SI$ increases as resolution increases, grazing angle decreases, and spectral strength increases. This trend is confirmed for center frequencies of 100 kHz and 10 kHz, as well as for power-law spectral exponents of 1.5, 2, and 2.5. The hypothesis that local tilting at the scale of the acoustic resolution is responsible for intensity fluctuations was examined using a representative model for the effect of slopes (inspired by the composite roughness approximation). It was found that slopes are responsible in part for the fluctuations, but other effects, such as multiple scattering and shadowing may also play a role.

Near such "superspinars," the efficiency of energy transfer from the accreting matter to radiation can reach 100%, compared to the maximum efficiency of 42% of the extremal Kerr (or 6% of the Schwarzschild) black hole. Finding such superspinning objects as active galactic nuclei, GBHCs, or sources of gamma ray bursts, could be viewed as experimental support for string theory.

description: Defect extremal surface is defined by extremizing the Ryu-Takayanagi formula corrected by the quantum defect theory. This is interesting when the AdS bulk contains a defect brane (or string). We introduce a defect extremal surface formula for reflected entropy, which is a mixed state generalization of entanglement entropy measure. Based on a decomposition procedure of an AdS bulk with a brane, we demonstrate the equivalence between defect extremal surface formula and island formula for reflected entropy in AdS$_3$/BCFT$_2$. We also compute the evolution of reflected entropy in evaporating black hole model and find that defect extremal surface formula agrees with island formula.

description: Multidisciplinary research at the oasis of Tayma, Northwest Arabia, revealed further information on the beginning of oasis cultivation towards the end of the 5th millennium BC and subsequently on the establishment of a substantial 3rd millennium BC occupation also at the centre of the site. Tayma was a significant place at that time with far reaching contacts to urban centres in neighbouring regions. On the long run, these relations laid the foundation for the oasis’ importance in the context of the 1st millennium BC overland caravan trade. Further investigations focused on 2nd and 1st millennium BC contexts of public and residential architecture at the site. The hydrological project continued its work on the reconstruction of the pertaining resource management. First epigraphic investigations in the hinterland of the oasis were also carried out.

description: The Wadi Shuʿaib Archaeological Survey Project (WSAS) was initiated in 2016. During the fall of 2016, a first preliminary survey campaign was conducted in the region of the Wadi Shuʿaib, stretching from the town of as-Salt in the northwest to the Jordan Valley (Shuna South) in the southwest of Central Jordan. During the first survey campaign, altogether fourteen archaeological sites were recorded, most of which were hitherto unknown, while others were already known to the scholarly community, but never recorded and documented thoroughly. The aim of the survey in future campaigns is to record all archaeological sites in this micro region connecting the fertile Jordan Valley with the Transjordanian Highlands.

description: Analogous to cuprate high-Tc superconductors, a NiP-based compound system has several crystals in which the Ni-P layers have different stacking structures. Herein, the properties of BaNi2P2 are reported. BaNi2P2 has an infinite-layer structure, and shows a superconducting transition at ~3 K. Moreover, it exhibits metallic conduction and Pauli paramagnetism in the temperature range of 4-300 K. Below 3 K, the resistivity sharply drops to zero, and the magnetic susceptibility becomes negative, while the volume fraction of the superconducting phase estimated from the diamagnetic susceptibility reaches ~100 vol.% at 1.9 K. These observations substantiate that BaNi2P2 is a bulk superconductor.

description: In the framework of the archaeological survey project “Arid habitats in the 5th to the early 3rd millennium BC: mobile subsistence, communication and key resource use in the Northern Badia (NE-Jordan)” (2010–2014) abundant indications for Late Prehistoric and especially Early Bronze Age socio-economic activities were revealed in the northern Badia in northeastern Jordan. With regards to these indications, the discoveries of the two fortified settlements Khirbet Abu al-Husayn and Tulul al-Ghusayn east of Jawa were of special interest. This led to the launch of the follow-up project “The colonization of the Northern Badia (NE-Jordan) in the Late Chalcolithic and Early Bronze Age (4th to 3rd millennium BC): a contribution to archaeological settlement geography in the arid regions of Southwest Asia”: It focuses on these permanent inhabited settlements, their chronological framework, the socio-economic background of the settlement’s residents and especially the identification of further comparable and contemporaneous settlements in the region. The first fieldwork season in spring 2015 focused on Tulul al-Ghusayn, where the visible architecture and terraced garden structures of the entire site were documented. Several soundings revealed information on the socio-economic background and the age of the settlement, which could be dated to the mid of the 4th millennium calBC.
Reprocessing of X-rays in the outer accretion disc of the black hole binary XTE J1817--330

description: We build a simple model of the optical/UV emission from irradiation of the outer disc by the inner disc and coronal emission in black hole binaries. We apply this to the broadband Swift data from the outburst of the black hole binary XTE J1817--330 to confirm previous results that the optical/UV emission in the soft state is consistent with a reprocessing a constant fraction of the bolometric X-ray luminosity. However, this is very surprising as the disc temperature drops by more than a factor 3 in the soft state, which should produce a marked change in the reprocessing efficiency. The easiest way to match the observed constant reprocessed fraction is for the disc skin to be highly ionized (as suggested 30 years ago by van Paradijs), so that the bulk of the disc flux is reflected and only the hardest X-rays heat the disc. The constant reprocessed fraction also favours direct illumination of the disc over a scattering origin as the optical depth/solid angle of any scattering material (wind/corona) over the disc should decrease as the source luminosity declines. By contrast, the reprocessed fraction increases very significantly (by a factor ~6) as the source enters the hard state. This dramatic change is not evident from X-ray/UV flux correlations as it is masked by bandpass effects. However, it does not necessarily signal a change in emission e.g. the emergence of the jet dominating the optical/UV flux as the reflection albedo must change with the dramatic change in spectral shape.

(3+1)-Formulation for Gravity with Torsion and Non-Metricity II: The Hypermomentum Equation

description: In this article, we consider a special case of Metric-Affine f(R)-gravity for f(R) = R, i.e. the Metric-Affine General Relativity (MAGR). As a companion to the first article in the series, we perform the (3+1) decomposition to the hypermomentum equation, obtained from the minimization of the MAGR action S [g, ω] with respect to the connection ω. Moreover, we show that the hypermomentum tensor H could be constructed completely from 10 hypersurfaces variables that arise from its dilation, shear, and rotational (spin) parts. The (3+1) hypermomentum equations consists of 1 scalar, 3 vector, 3 matrix, and 1 tensor equation of order-(2,1). Together with the (3+1) decomposition of the traceless torsion constraint, consisting of 1 scalar and 1 vector equation, we obtain 10 hypersurface equations, which are the main result in this article. Finally, we consider some special cases of MAGR, namely, the zero hypermomentum, metric, and torsionless cases. For vanishing hypermomentum, we could retrieve the metric compatibility and torsionless condition in the (3+1) framework, hence forcing the affine connection to be Levi-Civita as in the standard General Relativity.

description: Qasr Mushash, located east of Amman, belongs to the so-called desert castles, which form a distinctive group of monuments dating to the Early Islamic period. Archaeological field work carried out at the site in recent years indicates both the complexity of the building structures and a certain amount of effort in the construction of this extensive settlement. Although written sources about this place are missing, it is likely to have constituted an important stop on the route between Amman and Inner Arabia in the Umayyad period.
Parametrized spaces model locally constant homotopy sheaves

description: We prove that the homotopy theory of parametrized spaces embeds fully and faithfully in the homotopy theory of simplicial presheaves, and that its essential image consists of the locally homotopically constant objects. This gives a homotopy-theoretic version of the classical identification of covering spaces with locally constant sheaves. We also prove a new version of the classical result that spaces parametrized over X are equivalent to spaces with an action of the loop space of X. This gives a homotopy-theoretic version of the correspondence between covering spaces over X and sets with an action of the fundamental group of X. We then use these two equivalences to study base change functors for parametrized spaces.

description: A central aspect of any excavation is the documentation. The excavation and the removal of layers irrevocably destroy the contexts. That makes it necessary to document all the finds and features exactly and in as much detail as possible, so that conclusions are comprehensible in hindsight and it is possible to correct any misinterpretations. That is why the “Gadara Region project” is focused since 2011 on the publication of all results of the eighteen excavation campaigns that took place between 2004 and 2011 as well as the ones from the survey conducted in 2001 on the tell and the hinterland survey between 2009 and 2012. The fourth documentation campaign took place from May to June 2015.

description: The site of eh-Sayyeh is one of the most important Neolithic settlements in northern Jordan and was 2013–2015 subject of extensive soundings. The main objective was the study of the transition between the early and late Neolithic period at the end of the 8th / beginning of the 7th century BC. By evaluating the lithic material, simplified production techniques could be demonstrated, which were applied mainly at household level. The manufacture of special types of tools, for which particular knowledge is required, is comparatively rare. However, the high number of borers in the tool kit indicates a certain specialisation in the tool production at the site.
