description: The authenticity of political candidates has become a decisive factor in their evaluation by the public. In response, political candidates employ self-presentation techniques to appear genuine to constituents, and social media provides politicians with new tools to perform authenticity. Yet, we still know little about how politicians construct authentic images and how their gender and modes of self-presentation influence perceived authenticity. In this study, we examine how politicians’ gender (male vs female) and modes of self-presentation (text-only, image-only, and text–image combined) affect perceived political authenticity. Results from a 2 × 3 online survey experiment in Germany (N = 1,485) show that gender alone does not explain differences in perceived political authenticity when self-presentation is held consistently. Furthermore, we do not find significant effects for different self-presentation modes in social media. Additional analyses reveal that physical attractiveness is the primary factor for higher authenticity ratings in our sample.

description: Herein, we present the easy-to-access synthesis of the perfluorotrityl cation (15F+) with commercial GaCl3 and the further functionalization of the para-fluorine atoms of 15F+ via halodefluorination using trimethylsilyl halides TMSX (X=Cl, Br). This gives access to equally reactive halogenated trityl derivatives (p-3Cl12F+ and p-3Br12F+), which can be handled at room temperature. The impact of the para-exchange on the electronic structure is determined by NMR and UV/Vis spectroscopy. Finally, the new synthons′ high hydride ion affinities are demonstrated computationally and experimentally by hydride abstraction from the short-chain, linear alkanes n-pentane and n-butane.

description: The number of non-negative integer matrices with given row and column sums appears in a variety of problems in mathematics and statistics but no closed-form expression for it is known, so we rely on approximations of various kinds. Here we describe a new such approximation, motivated by consideration of the statistics of matrices with non-integer numbers of columns. This estimate can be evaluated in time linear in the size of the matrix and returns results of accuracy as good as or better than existing linear-time approximations across a wide range of settings. We also use this new estimate as the starting point for an improved numerical method for either counting or sampling matrices using sequential importance sampling. Code implementing our methods is provided.

description: We demonstrate a transmon qubit readout based on the nonlinear response to a drive of polaritonic meters in-situ coupled to the qubit. Inside a 3D readout cavity, we place a transmon molecule consisting of a transmon qubit and an ancilla mode interacting via non-perturbative cross-Kerr coupling. The cavity couples strongly only to the ancilla mode, leading to hybridized lower and upper polaritonic meters. Both polaritons are anharmonic and dissipative, as they inherit a self-Kerr nonlinearity $U$ from the ancilla and effective decay $κ$ from the open cavity. Via the ancilla, the polariton meters also inherit the non-perturbative cross-Kerr coupling to the qubit. This results in a high qubit-dependent displacement $2χ> κ, ~U$ that can be read out via the cavity without causing Purcell decay. Moreover, the polariton meters, being nonlinear resonators, present bistability, and bifurcation behavior when the probing power increases. In this work, we focus on the bifurcation at low power in the few-photon regime, called the mesoscopic regime, which is accessible when the self-Kerr and decay rates of the polariton meter are similar $U\sim κ$. Capitalizing on a latching mechanism by bifurcation, the readout is sensitive to transmon qubit relaxation error only in the first tens of nanoseconds. We thus report a single-shot fidelity of 98.6 $\%$ while having an integration time of a 500 ns and no requirement for an external quantum-limited amplifier.

description: This study explores the young profession of school guidance counseling in Bhutan. It investigated Bhutanese school guidance counselors' demographic characteristics, activities, roles, and responsibilities. The characteristics were assessed using quantitative survey measures, including the International Survey of School Counseling Activities (ISSCA). We further investigated their self-reported challenges and resources using open-ended questions analyzed using content analysis and the analysis of Strengths, Weaknesses, Opportunities, and Threats (SWOT). Finally, we examined differences between the views of school guidance counselors in Bhutan and those of Bhutanese school stakeholders (school teachers and principals). Responses were obtained from 162 (90.5%) of the 179 school guidance counselors active at the time in Bhutan, 49 school teachers, and 16 school principals. The ISSCA results revealed that Bhutanese school guidance counselors, on average, rated the appropriateness of school guidance counseling activities higher compared to their school principal and school teacher colleagues but rated the activities of dealing with discipline cases and taking on administrative duties lower. The SWOT analysis further shed light on their challenges and resources, including the effects of the COVID-19 pandemic. The discussion of results, interpreted using Bronfenbrenner's Ecological Systems Theory (Bronfenbrenner 1995) suggests that Bhutan's school guidance counseling profession needs more clearly defined roles, more time to establish itself, more initiatives to overcome stigma towards counseling, more material resources such as a counseling room and that schools need to make sure there is sufficient time and opportunities for students to see the school guidance counselor.

description: Small-scale eruptions could play an important role in coronal heating, generation of solar energetic particles (SEPs), and mass source of the solar wind. However, they are poorly observed, and their characteristics, distributions, and origins remain unclear. Here a mini coronal dimming was captured by the recently launched Solar Orbiter spacecraft. The observations indicate that a minifilament eruption results in the dimming and takes away approximately $(1.65\pm0.54)\times10^{13}$ g of mass, which also exhibits similar features as the sources of SEP events. The released magnetic free energy is of the order of $\sim10^{27}$ erg. Our results suggest that weak constraining force makes the flux rope associated with the minifilament easily enter a torus-unstable domain. We discuss that weak magnetic constraints from low-altitude background fields may be a general condition for the quiet-Sun eruptions, which provide a possible mechanism for the transport of coronal material and energy from the lower to the middle or even higher corona.

description: Gluon fusion is the main production mechanism for Higgs bosons with masses up to several hundred GeV in $pp$ collisions at the CERN Large Hadron Collider. We investigate the effects of the CP-violating phases on the fusion process including both the sfermion-loop contributions and the one-loop induced CP-violating scalar-pseudoscalar mixing in the minimal supersymmetric standard model. With a universal trilinear parameter assumed, every physical observable involves only the sum of the phases of the universal trilinear parameter $A$ and the higgsino mass parameter $μ$. The phase affects the lightest Higgs-boson production rate significantly through the neutral Higgs-boson mixing and, for the masses around the lightest stop-pair threshold, it also changes the production rate of the heavy Higgs bosons significantly through both the stop and sbottom loops and the neutral Higgs-boson mixing.

description: The paper provides a literatures review on the works on social vulnerability towards flood hazards. The problem of floods and hazards caused by them is mostly concerned so-called Third World countries due, firstly, to south climate specifics and, secondly, to the financial impossibility of their government to cope with danger. Ability to take under control and sometimes to correct the forces of nature can reduce strongly vulnerability of people to flood hazards. At the same time, controlling these huge nature mechanisms requires good economic investments. There are different mechanisms of how people can reduce their influence, mostly by controlling them: regular scientific observation in form of hydrographs, construction works, such as channelization and dams.

description: Effects of multi-gradient fields on the transport of a polymer chain have been investigated by using generalized Langevin dynamics simulations. We observe that the natural frequency of tumbling follows $Wi^{0.66}$ scaling, where $Wi$ is the Weissenberg number. Analysis of angular tumbling time distribution reveals that the tail of distribution follows exponential distribution and at high Weissenberg number, deviates from Poisson behaviour. Competition between velocity gradient which results shear flow in the system, and solvent quality gradient arising due to the interaction among monomers revealed that there is another scaling associated with the angular tumbling time distribution. Moreover, at low temperature, we observe unusual behaviour that at intermediate shear rates, decay rate $ν$ decreases with $Wi$.

description: Interpersonal teacher behavior can be described with the Interpersonal Circumplex on the dimensions of communion (warmth, sensitivity) and agency (initiative, control). In an observational study, we investigated whether a teacher's interpersonal behavior in dyadic interactions with a student is complementary to the student's communion and scholastic competence: Does the teacher act communal to the extent that the student behaves communal, and does the teacher act more agentic the less competent the student is? In 39 primary and secondary schools, we conducted direct classroom observations for two teacher-student dyads each (78 dyads). Using Structural Summary Method, we found as expected that teacher communion was positively associated with student communion, to the detriment of students who have not yet learned to behave in a communal manner. Further, results showed a negative association between teacher agency and student competence, suggesting that teachers engaged in adaptive teaching. Results further showed that weak teacher communion was related to low student competence. We discuss the implications for teacher education and training, namely that teachers should be trained to prevent falling into patterns of dysfunctional, non-communal behavior when confronted with a particular set of student characteristics and behaviors.

description: Recent constructions of quantum low-density parity-check (QLDPC) codes provide optimal scaling of the number of logical qubits and the minimum distance in terms of the code length, thereby opening the door to fault-tolerant quantum systems with minimal resource overhead. However, the hardware path from nearest-neighbor-connection-based topological codes to long-range-interaction-demanding QLDPC codes is a challenging one. Given the practical difficulty in building a monolithic architecture for quantum computers based on optimal QLDPC codes, it is worth considering a distributed implementation of such codes over a network of interconnected quantum processors. In such a setting, all syndrome measurements and logical operations must be performed using high-fidelity shared entangled states between the processing nodes. Since probabilistic many-to-1 distillation schemes for purifying entanglement are inefficient, we investigate quantum error correction based entanglement purification in this work. Specifically, we employ QLDPC codes to distill GHZ states, as the resulting high-fidelity logical GHZ states can interact directly with the code used to perform distributed quantum computing (DQC), e.g. for fault-tolerant Steane syndrome extraction. This protocol is applicable beyond DQC since entanglement purification is a quintessential task of any quantum network. We use the min-sum algorithm (MSA) based iterative decoder for distilling $3$-qubit GHZ states using a rate $0.118$ family of lifted product QLDPC codes and obtain an input threshold of $\approx 0.7974$ under i.i.d. single-qubit depolarizing noise. This represents the best threshold for a yield of $0.118$ for any GHZ purification protocol. Our results apply to larger size GHZ states as well, where we extend our technical result about a measurement property of $3$-qubit GHZ states to construct a scalable GHZ purification protocol.

description: The Ward-Takahashi identities are considered as the generalization of the Noether currents available to quantum field theory and include quantum fluctuation effects. Usually, they take the form of relations between correlation functions, which ultimately correspond to the relation between coupling constants of the theory. For this reason, they play a central role in the construction of renormalized theory, providing strong relations between counter-terms. Since last years, they have been intensively considered in the construction of approximate solutions for nonperturbative renormalization group of tensorial group field theories. The construction of these identities is based on the formal invariance of the partition function under a unitary transformation, and Ward's identities result from a first-order expansion around the identity. Due to the group structure of the transformation under consideration, it is expected that a first-order expansion is indeed sufficient. We show in this article that this does not seem to be the case for a complex tensor theory model, with a kinetic term involving a Laplacian.

The Role of the Ground Targets in the Atmospheric Correction of the EO Data

Publisher: name: figshare
Year: 2018
Subjects: subject: 90905 Photogrammetry and Remote Sensing
subject: FOS: Environmental engineering

description: Empirical atmospheric correction techniques, like EML or RELM methods, use measurements of reflectance on the ground using ground targets. The purpose of the ground targets in atmospheric correction of Earth observation data is to set a clear, single, well-characterised targets that will serve as model, standard examples of these types of Earth surface. The ground targets are stable, unchanging temporarily and spectrally flat, that's why they are important for the atmospheric correction of the airborne images. The uniform special-temporal stability of the GCP's is necessary for the calibration and atmospheric correction of the EO data. Provision of spectral ground target data for the image classification is therefore a technique which is widely used in radiometric calibration and quantitative analysis (Rollin et al). The target size is related to the sensor spatial resolution, radiometric quality and also to other site-specific factors such as atmospheric conditions and the contrasting reflectance of surrounding surfaces. The ground data are important key element in the techniques of the atmospheric correction both in ELM and in RELM methods for accurate results in image interpretation, because the empir- ical line method for the atmospheric correction is only possible when calibration ground target are available. Important is to choose targets ranged from dark reflectance targets (like asphalt) until those having bright reflective (e.g. concrete, sand, or light soils). Using correctly chosen ground targets allows to receive highly satisfactory results in the at- mospheric correction process of the EO data.

description: The two heavy quarks in a baryon which contains two heavy quarks and a light one, can constitute a scalar or axial vector diquark. We study electromagnetic radiations of such baryons, (i) Ξ_{(bc)_1} -> Ξ_{(bc)_0}+γ, (ii) Ξ_{(bc)_1}^* -> Ξ_{(bc)_0}+γ, (iii) Ξ_{(bc)_0}^{**}(1/2, l=1) -> Ξ_{(bc)_0}+γ, (iv) Ξ_{(bc)_0}^{**}(3/2, l=1) -> Ξ_{(bc)_0}+γand (v) Ξ_{(bc)_0}^{**}(3/2, l=2) -> Ξ_{(bc)_0}+γ, where Ξ_{(bc)_{0(1)}}, Ξ^*_{(bc)_1} are S-wave bound states of a heavy scalar or axial vector diquark and a light quark, and Ξ_{(bc)_0}^{**}(l is bigger than 1) are P- or D-wave bound states of a heavy scalar diquark and a light quark. Analysis indicates that these processes can be attributed into two categories and the physical mechanisms which are responsible for them are completely distinct. Measurements can provide a good judgment for the diquark structure and better understanding of the physical picture.

description: We show how two different mobile-immobile type models explain the observation of negative diffusion of excitons reported in experimental studies in quasi-two-dimensional semiconductor systems. The main reason for the effect is the initial trapping and a delayed release of free excitons in the area close to the original excitation spot. The density of trapped excitons is not registered experimentally. Hence, the signal from the free excitons alone includes the delayed release of not diffusing trapped particles. This is seen as the narrowing of the exciton density profile or decrease of mean-squared displacement which is then interpreted as a negative diffusion. The effect is enhanced with the increase of recombination intensity as well as the rate of the exciton-exciton binary interactions.

We show that there is no Luscher c/R term in the static-quark potential, which is contrary to both the prediction of various effective string models, and the results of some recent lattice Monte Carlo studies. It is also noted that the glueball masses extracted from classical supergravity tend to finite, coupling-independent constants in the strong coupling limit, even as the string tension tends to infinity in the same limit; this is a counter-intuitive result.

description: Software-defined networks (SDN) enable flexible and effective communication systems that are managed by centralized software controllers. However, such a controller can undermine the underlying communication network of an SDN-based system and thus must be carefully tested. When an SDN-based system fails, in order to address such a failure, engineers need to precisely understand the conditions under which it occurs. In this article, we introduce a machine learning-guided fuzzing method, named FuzzSDN, aiming at both (1) generating effective test data leading to failures in SDN-based systems and (2) learning accurate failure-inducing models that characterize conditions under which such system fails. To our knowledge, no existing work simultaneously addresses these two objectives for SDNs. We evaluate FuzzSDN by applying it to systems controlled by two open-source SDN controllers. Further, we compare FuzzSDN with two state-of-the-art methods for fuzzing SDNs and two baselines for learning failure-inducing models. Our results show that (1) compared to the state-of-the-art methods, FuzzSDN generates at least 12 times more failures, within the same time budget, with a controller that is fairly robust to fuzzing and (2) our failure-inducing models have, on average, a precision of 98% and a recall of 86%, significantly outperforming the baselines.
Radiative Decays of Heavy Mesons and the Determination of the Strong g-Coupling

description: The strong g-coupling characterizes the interaction of heavy mesons with pions in typical vertices $H^*Hπ$, $H^*H^*π$, where $(H^*;H)$ stands for vector and pseudoscalar $(B^*;B)$ or $(D^*;D)$ heavy mesons. Its estimation by different theoretical methods has led to a wide range of possible values. We describe a new approach to the determination of g, which exploits the rare radiative decays $B^*\to Bγγ$ and $D^*\to Dγγ$. It is shown that the branching ratio of $D^*\to Dγγ$ can be expressed as a function of a single unknown $g$ and we calculate it to be in the measurable range between $1.6\times 10^{-6}$ and $3.3\times 10^{-5}$ for 0.25 < g < 1.

We show that these kind of heterostructures are very stable due to extreamly low interfacial strain. The formation of a 2DEG/2DHG has been investigated in case of Zn$_2$Mo$_3$O$_8$/Mg$_2$Mo$_3$O$_8$ and polarization discontinuity has been found to be driving mechanism. The sheet carrier densities and charge localization in these kind of heterostrcutures have been found to be of the same order of magnitude in other well known system that hosts 2DEG through similar mechanism, such as AlN/Al(Ga)N or ZnO/Zn(Mg)O. In addition to conventional applications of a 2DEG, these materials hold promise to exciting pioneering technolgy such as piezo-phototronics using solar radiation, as they are also capable of absorbing a significant fraction of it due to low optical gap of $\sim$ 2 eV

description: Modern neural networks are over-parameterized and thus rely on strong regularization such as data augmentation and weight decay to reduce overfitting and improve generalization. The dominant form of data augmentation applies invariant transforms, where the learning target of a sample is invariant to the transform applied to that sample. We draw inspiration from human visual classification studies and propose generalizing augmentation with invariant transforms to soft augmentation where the learning target softens non-linearly as a function of the degree of the transform applied to the sample: e.g., more aggressive image crop augmentations produce less confident learning targets. We demonstrate that soft targets allow for more aggressive data augmentation, offer more robust performance boosts, work with other augmentation policies, and interestingly, produce better calibrated models (since they are trained to be less confident on aggressively cropped/occluded examples). Combined with existing aggressive augmentation strategies, soft target 1) doubles the top-1 accuracy boost across Cifar-10, Cifar-100, ImageNet-1K, and ImageNet-V2, 2) improves model occlusion performance by up to $4\times$, and 3) halves the expected calibration error (ECE). Finally, we show that soft augmentation generalizes to self-supervised classification tasks. Code available at https://github.com/youngleox/soft_augmentation

description: The new mechanism for the generation of the chiral generations is proposed based on the SU(1,1) horizontal gauge symmetry. The appearance of the chiral generations is controlled by the coupling constant s of the model. This is crucial in the grand unification scheme. The resulting chiral generations naturally acquire the hierarchal Yukawa coupli ng matrices. Propriety of the model to the observed hierarchical structure is discussed nume rically under the minimal parameter set.

description: The late-time nonlinear Lagrangian displacement field is highly correlated with the initial field, so reconstructing it could enable us to extract primordial cosmological information. Our previous work [1] carefully studied the displacement field reconstructed from the late time density field using the iterative method proposed by Ref. [2] and found that it does not fully converge to the true, underlying displacement field (e.g., $\sim 8\%$ offset at $k\sim 0.2 \ihMpc$ at $z=0.6$). We also constructed the Lagrangian perturbation theory model for the reconstructed field, but the model could not explain the discrepancy between the true and the reconstructed fields in the previous work. The main sources of the discrepancy were speculated to be a numerical artifact in the displacement estimator due to the discreteness of the sample. In this paper, we develop two new estimators of the displacement fields to reduce such numerical discreteness effect, the normalized momentum estimator~(NME) and the rescaled resumed estimator~(RRE). We show that the discrepancy Ref. [1] reported is not due to the numerical artifacts. We conclude that the method from Ref. [2] cannot fully reconstruct the shape of the nonlinear displacement field at the redshift we studied, while it is still an efficient BAO reconstruction method. In parallel, by properly accounting for the UV-sensitive term in a reconstruction procedure with an effective field theory approach, we improve the theoretical model for the reconstructed displacement field, by almost five times, from $\sim 15\%$ to the level of a few \% at $k\sim 0.2\ihMpc$ at the redshift $z=0.6$.

description: Recently, there has been a growing interest for mixed-categorical meta-models based on Gaussian process (GP) surrogates. In this setting, several existing approaches use different strategies either by using continuous kernels (e.g., continuous relaxation and Gower distance based GP) or by using a direct estimation of the correlation matrix. In this paper, we present a kernel-based approach that extends continuous exponential kernels to handle mixed-categorical variables. The proposed kernel leads to a new GP surrogate that generalizes both the continuous relaxation and the Gower distance based GP models. We demonstrate, on both analytical and engineering problems, that our proposed GP model gives a higher likelihood and a smaller residual error than the other kernel-based state-of-the-art models. Our method is available in the open-source software SMT.

description: A remarkable feature of the models with interactions exhibiting higher-spin (HS) gauge symmetries in $d>2$ is that their most symmetric vacua require (anti)-de Sitter (AdS) geometry rather than the flat one. In striking parallelism to what might be expected of M theory HS gauge theories describe infinite towers of fields of all spins and possess naturally space-time SUSY and Chan-Paton type inner symmetries. In this paper, we analyze at the level of the equations of motion the simplest non-trivial HS model which describes HS gauge interactions (on the top of the usual supergravitational and (Chern-Simons) Yang-Mills interactions) of massive spin-0 and spin-1/2 matter fields in d=2+1 AdS space-time. The parameter of mass of the matter fields is identified with the vev of a certain auxiliary field in the model. The matter fields are shown to be arranged into d3 N=2 massive hypermultiplets in certain representations of $U(n)\times U(m)$ Yang-Mills gauge groups. Discrete symmetries of the full system are studied, and the related N=1 supersymmetric truncations with O(n) and Sp(n) Yang-Mills symmetries are constructed. The simplicity of the model allows us to elucidate some general properties of the HS models. In particular, a new result, which can have interesting implications to the higher-dimensional models, is that our model is shown to admit an "integrating" flow that proves existence of a non-local Bäcklund-Nicolai-type mapping to the free system.

description: Semiconductor quantum dots operated dynamically are the basis of many quantum technologies such as quantum sensors and computers. Hence, modelling their electrical properties at microwave frequencies becomes essential to simulate their performance in larger electronic circuits. Here, we develop a self-consistent quantum master equation formalism to obtain the admittance of a quantum dot tunnel-coupled to a charge reservoir under the effect of a coherent photon bath. We find a general expression for the admittance that captures the well-known semiclassical (thermal) limit, along with the transition to lifetime and power broadening regimes due to the increased coupling to the reservoir and amplitude of the photonic drive, respectively. Furthermore, we describe two new photon-mediated regimes: Floquet broadening, determined by the dressing of the QD states, and broadening determined by photon loss in the system. Our results provide a method to simulate the high-frequency behaviour of QDs in a wide range of limits, describe past experiments, and propose novel explorations of QD-photon interactions.
