description: In this letter, we study the PXP Hamiltonian with an external magnetic field that exhibits both quantum scar states and quantum criticality. It is known that this model hosts a series of quantum many-body scar states violating quantum thermalization at zero magnetic field, and it also exhibits an Ising quantum phase transition driven by finite magnetic field. Although the former involves the properties of generic excited states and the latter concerns the low-energy physics, we discover two surprising connections between them, inspired by the observation that both states possess log-volume law entanglement entropies. First, we show that the quantum many-body scar states can be tracked to a set of quantum critical states, whose nature can be understood as pair-wisely occupied Fermi sea states. Second, we show that the partial violation of quantum thermalization diminishes in the quantum critical regime. We envision that these connections can be extended to general situations and readily verified in existing cold atom experimental platforms.

description: It is well known that gravitons can convert into photons, and vice versa, in the presence of cosmological magnetic fields. We study this conversion process in the context of atomic dark matter scenario. In this scenario, we can expect cosmological dark magnetic fields, which are free from the stringent constraint from the cosmic microwave observations. We find that gravitons can effectively convert into dark photons in the presence of cosmological dark magnetic fields. The graviton-dark photon conversion effect may open up a new window for ultra high frequency gravitational waves.

description: We formulate a full-counting statistics description to study energy exchange in multi-terminal junctions. Our approach applies to quantum systems that are coupled either additively or non-additively (cooperatively) to multiple reservoirs. We derive a Markovian Redfield-type equation for the counting-field dependent reduced density operator. Under the secular approximation, we confirm that the cumulant generating function satisfies the heat exchange fluctuation theorem. Our treatment thus respects the second law of thermodynamics. We exemplify our formalism on a multi-terminal two-level quantum system, and apply it to realize the smallest quantum absorption refrigerator, operating through engineered reservoirs, and achievable only through a cooperative bath interaction model.

description: Starting from the geometrical interpretation of integrable vortices on two-dimensional hyperbolic space as conical singularities, we explain how this picture can be expressed in the language of Cartan connections, and how it can be lifted to the double cover of three-dimensional Anti-de Sitter space viewed as a trivial circle bundle over hyperbolic space. We show that vortex configurations on the double cover of AdS space give rise to solutions of the Dirac equation minimally coupled to the magnetic field of the vortex. After stereographic projection to (2+1)-dimensional Minkowski space we obtain, from each lifted hyperbolic vortex, a Dirac field and an abelian gauge field which solve a Lorentzian, (2+1)-dimensional version of the Seiberg-Witten equations.

Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics
subject: FOS: Computer and information sciences

description: While much work in human-robot interaction has focused on leaderfollower teamwork models, the recent advancement of robotic systems that have access to vast amounts of information suggests the need for robots that take into account the quality of the human decision making and actively guide people towards better ways of doing their task. This thesis proposes an equal-partners model, where human and robot engage in a dance of inference and action, and focuses on one particular instance of this dance: the robot adapts its own actions via estimating the probability of the human adapting to the robot. We start with a bounded-memory model of human adaptation parameterized by the human adaptability - the probability of the human switching towards a strategy newly demonstrated by the robot. We then examine more subtle forms of adaptation, where the human teammate adapts to the robot, without replicating the robot’s policy. We model the interaction as a repeated game, and present an optimal policy computation algorithm that has complexity linear to the number of robot actions. Integrating these models into robot action selection allows for human-robot mutual-adaptation. Human subject experiments in a variety of collaboration and shared-autonomy settings show that mutual adaptation significantly improves human-robot team performance, compared to one-way robot adaptation to the human.

description: We study condensation behaviors of static scalar fields in the regular asymptotically AdS reflecting star spacetime. With analytical methods, we provide upper bounds for the radii of the scalar hairy reflecting stars. Above the bound, there is no scalar hair theorem for the star. Below the bound, we numerically obtain charged scalar hairy reflecting star solutions and in particular, the radii of the hairy stars are discrete, which is similar to known results in other reflecting object backgrounds. For every set of parameters, we search for the largest AdS hairy star radius, study effects of parameters on the largest hairy star radius and also find difference between properties in this AdS reflecting star background and those in the flat reflecting star spacetime. Moreover, we show that scalar fields cannot condense around regular AdS reflecting stars when the star charge is small or the cosmological constant is negative enough.

description: Agricultural extension systems have been developed for people living in rural areas to deal with farm production and marketing activities which have been the main livelihoods of these people. Agricultural Extension is defined as the use of communication methods in a planned manner to help farmers make ideas and right decisions in every subject they need. However, people engaged in agriculture need help in production techniques, input use, marketing, and other activities regarding rural society. For this reason, agricultural extension agents, also called change agents, participate in the extension process to determine the problems of farmers by the most consistent and positive manner. Moreover, these agents provide a two-way link between research institutions and farmers and cooperate with rural development organizations.The overall purpose of this study is to examine the roles, responsibilities, and competencies of the agricultural extension agents in the extension systems,and to determine common strategies that maximize the impact of extension agents’ efforts for agricultural and rural development.The study begins with a basic need assessment for agricultural extension services and extension agents in the agricultural development process. Qualitative research methods were utilizedsince this was a review study.In this context, published articles, conference proceedings, books, statistics from official institutions and the private sector, and various web sites were used. The study concluded that an extension agent has a variety of roles and responsibilities. Furthermore, they need professional, individual, and technic competencies to fulfill their roles and responsibilities. It is thought that the research results will provide useful information for agricultural politicians, scientists, farmers, and extension staff.

description: We show that certain models for neutrino masses that lead to the MSW explanation of the solar neutrino data and/or the hot dark matter component in the universe can also naturally allow for the successful generation of the cosmological baryon asymmetry at the electroweak scale. This follows either because the experimental Higgs boson mass limit is weakened due to the smaller production rate and the presence of sizeable invisible decays involving majoron emission, or due to the effect of additional electrically charged scalar bosons which substantially modify the condition for succesful baryogenesis.

description: Turkey is a country with high young population rate. Also, after the internal conflicts that arose in neighboring countries, flocks of people have immigrated to Turkey. High population growth caused high food demand. Also, most of the population in Turkey is Muslim, and it is creating extra demand in the feast of sacrifice. During recent years, because of these reasons, the supply of meat could not meet the demand, and high demand increased the meat prices with high costs. The government of Turkey, therefore, started to import live animals to reduce meat prices. In this study, for the period 2005M01- 2018M01, the relationship between real effective exchange rate, real effective exchange rate volatility and Turkey’s livestock imports was examined using bounds test, symmetric and timevarying symmetric causality tests. In this study, unit root analysis was performed using ADF and PP tests. The results of ADF and PP unit root tests indicated that the parameters were stationary at different levels and that none of the parameters was stationary at the 2nd level. According to bounds test, the F-statistic value calculated at a significant level of 5% and 10% was found less than bottom limits, the cointegration relation between the variables was not determined. As a result of the bounds test, it was concluded that there was no long-term relationship between the variables. According to the results of a Hacker-Hatemi-J causality test, a causality relationship was not found from volatility, reel effective exchange rate and industrial production index to Turkey’s livestock exports. Timer varying causality analysis confirmed this result for a significant part of the time interval. However, a causality relationship was determined for some periods from volatility, reel effective exchange rate and industrial production index to Turkey’s livestock exports. In this study,for the period 2005M01- 2018M01, the relationship between real effective exchange rate, real effective exchange rate volatility and Turkey’s livestock imports was examined using bounds test, symmetric and time-varying symmetric causality tests.

description: The pollution and contamination assessment of three heavy metals (Cu, Pb, and Zn) in the topsoil, and common plants (Olea europaea, Prunus persica vulgaris, Ficus carica, Medicago sativa, Zygophyllum album, and Helianthemum kahiricum) were carried out at different distances from a cement plant. This evaluation was based on four evaluation methods: Bioconcentration factor, Contamination factor, Geoaccumulation Index and Potential ecological risk factor. The chlorophylls a and b contents were also analyzed. The highest levels of Cu, Zn, and Pb in the topsoil were found close to the cement factory (cluster D), and the lowest values were observed in a distant oasis (cluster H). The lowest chlorophylls values were observed in perennial plants (O. europaea and F. carica) near the cement plant. Zygophyllum album and H. kahiricum showed capability to remove Cu an Zn in contaminated locations, depending on the soil type. The spatialization of the results was essential to the understanding of the potential contribution of different sources of Cu, Zn, and Pb in the topsoil and to distinguishing different behaviors of the same plant species. Concerning H. kahiricum, further research should be undertaken since it has a high livestock acceptability index and is used in traditional medicine. Novelty statement The impact of three heavy metals (Cu, Zn, and Pb) on the topsoil and six species of plants common in Tunisia (arid climate) will be assessed, and the potential contribution of different sources to the contamination. Few studies have addressed the impact of cement dust in the topsoil and common plant species in arid rangelands, and, as far as we know, none of them have considered the spatialization of the data and results, considering the prevailing wind, plant species location, soil type, and use. Moreover, the ability of steppic vegetation to remove these three heavy metals (phytoextraction) was evaluated using the bioconcentration factor (BCF), soil pollution indices, and ecological risk. Chlorophylls a and b contents were also evaluated to establish the effect of the cement plant on the health of plants located nearby.

description: The quantum properties of two-dimensional matter-dilaton gravity ---which includes a large family of actions for two-dimensional gravity (in particular, string-inspired models)--- are investigated. The one-loop divergences in linear covariant gauges are calculated and the structure of the one-loop renormalization is studied. The explicit forms of the dilaton potential, dilaton-Maxwell, and dilaton-scalar couplings for which the theory is one-loop multiplicatively renormalizable are found. A comparison with the one-loop renormalization structure of four-dimensional gravity-matter theory is given. Charged multiple-horizon black holes which appear in the model are also considered.

description: In this paper we report on the gas-phase abundance of singly-ionized magnesium (Mg II) in 44 lines of sight, using data from the Hubble Space Telescope (HST). We measure Mg II column densities by analyzing medium- and high-resolution archival STIS spectra of the 1240 A doublet of Mg II. We find that Mg II depletion is correlated with many line of sight parameters (e.g. F(H_2), E_(B-V), E_(B-V)/r, A_V, and A_V/r) in addition to the well-known correlation with . These parameters should be more directly related to dust content and thus have more physical significance with regard to the depletion of elements such as magnesium. We examine the significance of these additional correlations as compared to the known correlation between Mg II depletion and . While none of the correlations are better predictors of Mg II depletion than , some are statistically significant even assuming fixed . We discuss the ranges over which these correlations are valid, their strength at fixed , and physical interpretations.

description: Phytoremediation is one of the biological approaches for remediating textile dyeing effluents. The objective of this study is the use of Pistia stratiotes, an aquatic macrophyte, which was found to degrade the maximum of 83% of mixed azo dye. A phytoreactor was designed and constructed to scale up the process of phytoremediation by P. stratiotes to treat 40 mg/l of synthetic textile effluent. Continuous flow phytoreactor fed with 40 mg/l (cycle 1) which showed maximum decolorization of 84%, COD removal was about 61%, BOD which was reduced up to 71.9%, and TDS removal was about 72% respectively. Further to remove the residual color and toxic effects of the dyes, Phycoremediation was followed for the mixed azo dyes using the microalgae Chlorella vulgaris which showed a maximum decolorization of 99% in the batch study and 74% in the scale-up study where the treated effluent was at the most minimal discharge. Phytotoxicity tests showed 80% of germination in treated effluent, and the plants in untreated wastewater had inhibited growth that indicates only 30% of germination. Such combined biological treatment techniques were put forward to be the most eco-friendly technology, which is cost-effective and attain zero discharge of the textile effluent.

description: This scoping literature review maps the existing scientific literature on intersectional policies in Higher Education and Research institutes (HE&R). Intersectional policies aim to address inequalities and discrimination that occur along multiple, intersecting identity axes including but not limited to gender, race, ethnicity, disability, age and sexual orientation, and which operate on different levels. While there is a growing body of literature on intersectionality that deals with persisting intersecting inequalities in research organizations, less is known on how an intersectional approach can be incorporated into policies and practices to ensure a more inclusive HE&R (Christoffersen 2021).
The goal of this scoping literature review is to identify which scientific literature is available on the topic and what are the current knowledge gaps through well-defined research questions, systematic searches and clear inclusion/exclusion criteria (Arksey and O'Malley 2005; Peters et al. 2020). The following research question was formulated: What is known from the existing literature on the use of intersectionality in equality policies of Higher Education and Research organizations?

description: Deflagration models poorly explain the observed diversity of SNIa. Current multidimensional simulations of SNIa predict a significant amount of, so far unobserved, carbon and oxygen moving at low velocities. It has been proposed that these drawbacks can be resolved if there is a sudden jump to a detonation (delayed detonation), but this kind of models has been explored mainly in one dimension. Here we present new three-dimensional delayed detonation models in which the deflagraton-to-detonation transition (DDT) takes place in conditions like those favored by one-dimensional models. We have used a SPH code adapted to SNIa with algorithms devised to handle subsonic as well as supersonic combustion fronts. The starting point was a C-O white dwarf of 1.38 solar masses. When the average density on the flame surface reached 2-3x10^7 g/cm^3 a detonation was launched. The detonation wave processed more than 0.3 solar masses of carbon and oxygen, emptying the central regions of the ejecta of unburned fuel and raising its kinetic energy close to the fiducial 10^51 ergs expected from a healthy Type Ia supernova. The final amount of 56Ni synthesized also was in the correct range. However, the mass of carbon and oxygen ejected is still too high. The three-dimensional delayed detonation models explored here show an improvement over pure deflagration models, but they still fail to coincide with basic observational constraints. However, there are many aspects of the model that are still poorly known (geometry of flame ignition, mechanism of DDT, properties of detonation waves traversing a mixture of fuel and ashes). Therefore, it will be worth pursuing its exploration to see if a good SNIa model based on the three-dimensional delayed detonation scenario can be obtained.

In this paper: (1) We present a debloating framework built on a compiler toolchain that can successfully debloat programs (shared/static libraries and executables). Our solution can successfully compile and load most libraries on Ubuntu Desktop 16.04. (2) We demonstrate the elimination of over 79% of code from coreutils and 86% of code from SPEC CPU 2006 benchmark programs without affecting functionality. We show that even complex programs such as Firefox and curl can be debloated without a need to recompile. (3) We demonstrate the security impact of debloating by eliminating over 71% of reusable code gadgets from the coreutils suite and show that unused code that contains real-world vulnerabilities can also be successfully eliminated without adverse effects on the program. (4) We incur a low load time overhead.

description: Recently, a series of theoretical and experimental papers on free-space propagation of pulsed Laguerre-Gaussian and Bessel beams was published, which reached contradictory and controversial results about group velocities of such pulses. Depending on themeasurement scheme, the group velocity can be defined differently.We analyze how different versions of group velocity are related to the measurable travel time (time of flight) of the pulse between input (source) and output (detecting) planes. The analysis is tested on a theoretical model---the Bessel-Gauss pulse whose propagation path exhibits both subluminal and superluminal regions. Our main conclusion from resolving the contradictions in the literature is that different versions of group velocity are appropriate, depending on whether or not the beam is hollow and how the pulse is recorded in the output plane---integrally or with spatial resolution.

description: A new quantum mechanical wave equation describing a particle with frictional forces is derived. It depends on a parameter $α$ whose range is determined by the coefficient of friction $γ$, that is, $0 \leq α\leq γ$. For one extreme value of this parameter, $α= 0$, we recover Kostin's equation. For the other extreme value, $α= γ$, we obtain an equation in which friction manifests in "magnetic" type terms. It further exhibits breakdown of translational invariance, manifesting through a symmetry breaking parameter $β$, as well as localized stationary states in the absence of external potentials. Other physical properties of this new class of equations are also discussed.

Material Gradients in Thin Stretchable Substrates for Wearable Electronics

Publisher: name: Carnegie Mellon University
Year: 2016
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: Stretchable electronics garners attention for its promise in unobtrusive wearable systems for health monitoring and potentially for medical therapy. One significant question though is whether to develop holistic stretchable electronics where the process steps for electronic and mechanical functions are interwoven, or to integrate mature CMOS into stretchable electronic substrates where the CMOS process is separate from mechanical process steps. A major limitation with integrating CMOS is the interface between the soft and hard materials when introduced into functional systems. To address this, we have developed a new platform for stretchable electronics with the ability to embed hard CMOS based substrates that are prevalent in electronic and sensing devices. Through integrating and connecting small CMOS chips spread through an elastomeric substrate, the final system will have highly functional electronic attributes, while being stretchable because of the high percentage of low modulus elastomers. However, in general, delamination readily occurs when a stretchable substrate with embedded thinned chips is strained. We have developed an approach to control the elasticity of the polymer layers around the hard materials associated with CMOS electronic parts to create a controllable material stiffness gradient interfacing a highly rigid material to the soft stretchable system. This approach enables a thin stretchable system that adheres to the skin, but has hard CMOS based materials distributed through its matrix. Our coupled computational and experimental approach reveals that adding just one controlled layer in the material gradient results in a 5.5 times increase in the strain failure threshold. This huge increase in strain failure threshold decreases the risk of delamination. Also, we have developed an approach to pattern an elastomeric polymer layer with spatially varying mechanical properties around CMOS electronics to create a controllable material stiffness gradient. Our experimental approach reveals that modifying the interfaces can increase the strain failure threshold up to 30% and subsequently decreases delamination. The stiffness gradient in the v polymer layer provides a safe region for electronic chips to function under a substrate tensile strain up to 150%. These results will have impacts in diverse applications including skin sensors and wearable health monitoring systems.
Planet formation around stars of various masses: The snow line and the frequency of giant planets

description: We use a semi-analytic circumstellar disk model that considers movement of the snow line through evolution of accretion and the central star to investigate how gas giant frequency changes with stellar mass. The snow line distance changes weakly with stellar mass; thus giant planets form over a wide range of spectral types. The probability that a given star has at least one gas giant increases linearly with stellar mass from 0.4 M_sun to 3 M_sun. Stars more massive than 3 M_sun evolve quickly to the main-sequence, which pushes the snow line to 10-15 AU before protoplanets form and limits the range of disk masses that form giant planet cores. If the frequency of gas giants around solar-mass stars is 6%, we predict occurrence rates of 1% for 0.4 M_sun stars and 10% for 1.5 M_sun stars. This result is largely insensitive to our assumed model parameters. Finally, the movement of the snow line as stars >2.5 M_sun move to the main-sequence may allow the ocean planets suggested by Leger et. al. to form without migration.

description: Recent studies in spintronics have highlighted ultrathin magnetic metallic multilayers as a novel and very promising class of broadband terahertz radiation sources. Such spintronic multilayers consist of ferromagnetic (FM) and non-magnetic (NM) thin films. When triggered by ultrafast laser pulses, they generate pulsed THz radiation due to the inverse spin-Hall effect, a mechanism that converts optically driven spin currents from the magnetized FM layer into transient transverse charge currents in the NM layer, resulting in THz emission. As THz emitters, FM/NM multilayers have been intensively investigated so far only at 800-nm excitation wavelength using femtosecond Ti:sapphire lasers. In this work, we demonstrate that an optimized spintronic bilayer structure of 2-nm Fe and 3-nm Pt grown on 500 μm MgO substrate is just as effective as a THz radiation source when excited either at λ = 800 nm or at λ = 1550 nm by ultrafast laser pulses from a fs fiber laser (pulse width close to 100 fs, repetition rate around 100 MHz). Even with low incident power levels, the Fe/Pt spintronic emitter exhibits efficient generation of THz radiation at both excitation wavelengths. The efficient THz emitter operation at 1550 nm facilitates the integration of such spintronic emitters in THz systems driven by relatively low cost and compact fs fiber lasers without the need for frequency conversion.

description: We consider an $SU(3)_L\otimes U(1)_N$ model for the electroweak interactions which includes extra charged leptons which do not mix with the known leptons. These new leptons couple to $Z^0$ only through vector currents. We consider constraints on the mass of one of these leptons coming from the $Z^0$-width and from the muon $(g-2)$ factor. The last one is less restrictive than the former.

Checking Security Compliance between Models and Code

description: It is challenging to verify that the planned security mechanisms are actually implemented in the software. In the context of model-based development, the implemented security mechanisms must capture all intended security properties that were considered in the design models. Assuring this compliance manually is labor intensive and can be error-prone. This work introduces the first semi-automatic technique for secure data flow compliance checks between design models and code. We develop heuristic-based automated mappings between a design-level model (SecDFD, provided by humans) and a code-level representation (Program Model, automatically extracted from the implementation) in order to guide users in discovering compliance violations, and hence potential security flaws in the code. These mappings enable an automated, and project-specific static analysis of the implementation with respect to the desired security properties of the design model. We developed two types of security compliance checks and evaluated the entire approach on open source Java projects.
Simulating the pericentre passage of the Galactic centre star S2

description: The so-called S2 star reached its closest approach to the massive black hole (BH) at around 1500 $R_\mathrm{s}$ in May 2018. It has been proposed that the interaction of its stellar wind with the high-density accretion flow at this distance from Sgr A* will lead to a detectable, month-long X-ray flare. Our goal is to verify whether or not the S2 star wind can be used as a diagnostic tool to infer the properties of the accretion flow towards Sgr A* at its pericentre (an unprobed distance regime), putting important constraints on BH accretion flow models. We run a series of three-dimensional adaptive mesh refinement simulations with the help of the Ramses code which include the realistic treatment of the interaction of S2's stellar wind with the accretion flow along its orbit and - apart from hydrodynamical and thermodynamical effects - include the tidal interaction with the massive BH. These are post-processed to derive the X-ray emission in the observable 2-10 keV window. No significant excess of X-ray emission from Sgr A* is found for typical accretion flow models. A measurable excess is produced for a significantly increased density of the accretion flow. This can, however, be ruled out for standard power-law accretion flow models as in this case the thermal X-ray emission without the S2 wind interaction would already exceed the observed quiescent luminosity. Only a significant change of the wind parameters (increased mass loss rate and decreased wind velocity) might lead to an (marginally) observable X-ray flaring event. Even the detection of an (month-long) X-ray flare during the pericentre passage of the S2 star would not allow for strict constraints to be put on the accretion flow around Sgr A* due to the degeneracy caused by the dependence on multiple parameters (of the accretion flow model as well as the stellar wind).

description: In this work we present a new physics-informed machine learning model that can be used to analyze kinematic data from an instrumented mouthguard and detect impacts to the head. Monitoring player impacts is vitally important to understanding and protecting from injuries like concussion. Typically, to analyze this data, a combination of video analysis and sensor data is used to ascertain the recorded events are true impacts and not false positives. In fact, due to the nature of using wearable devices in sports, false positives vastly outnumber the true positives. Yet, manual video analysis is time-consuming. This imbalance leads traditional machine learning approaches to exhibit poor performance in both detecting true positives and preventing false negatives. Here, we show that by simulating head impacts numerically using a standard Finite Element head-neck model, a large dataset of synthetic impacts can be created to augment the gathered, verified, impact data from mouthguards. This combined physics-informed machine learning impact detector reported improved performance on test datasets compared to traditional impact detectors with negative predictive value and positive predictive values of 88% and 87% respectively. Consequently, this model reported the best results to date for an impact detection algorithm for American Football, achieving an F1 score of 0.95. In addition, this physics-informed machine learning impact detector was able to accurately detect true and false impacts from a test dataset at a rate of 90% and 100% relative to a purely manual video analysis workflow. Saving over 12 hours of manual video analysis for a modest dataset, at an overall accuracy of 92%, these results indicate that this model could be used in place of, or alongside, traditional video analysis to allow for larger scale and more efficient impact detection in sports such as American Football.
