description: We present a method for the arbitrage-free interpolation of plain-vanilla option prices and implied volatilities, which is based on a system of integral equations that relates terminal density and option prices. Using a discretization of the terminal density, we write these integral equations as a system of linear equations. We show that the kernel matrix of this system is in general ill-conditioned, so that it can not be solved for the discretized density using a naive approach. Instead, we construct a sparse model for the kernel matrix using the singular value decomposition (SVD), which allows us not only to systematically improve the condition number of the kernel matrix, but also determines the computational effort and accuracy of our method. In order to allow for the treatment of realistic inputs that may contain arbitrage, we reformulate the system of linear equations as an optimization problem, in which the SVD-transformed density minimizes the error between the input prices and the arbitrage-free prices generated by our method. To further stabilize the method in the presence of noisy input prices or arbitrage, we apply an $L_1$-regularization to the SVD-transformed density. Our approach, which is inspired by recent progress in theoretical physics, offers a flexible and efficient framework for the arbitrage-free interpolation of plain-vanilla option prices and implied volatilities, without the need to explicitly specify a stochastic process, expansion basis functions or any other kind of model. We demonstrate the capabilities of our method on a number of artificial and realistic test cases.
Optimally displaced threshold detection for discriminating coherent states

description: Discriminating two coherent states is a fundamental problem in both classical and quantum communications. The optimal quantum detection for discriminating two coherent states requires real-time feedback loops and high control complexity. Therefore, it is of practical importance to study near-optimum quantum detection techniques having simple implementation structures. Our research aim is to study one promising near-optimum quantum detection, the optimally displaced threshold detection (ODTD) for a generalized Kennedy receiver. We first analytically study the performance of the Kennedy-like receiver with ODTD in a realistic optical fiber communication (OFC) system with noises and imperfect devices. Then we propose a heuristic greedy search algorithm to design these parameters. We prove that the ODTD asymptotically approaches the Kennedy receiver with threshold detection when the signal power is large. We also clarify the connection between the generalized Kennedy receiver with threshold detection and the one-port homodyne detection. We show that the ODTD can outperform the homodyne detection in a realistic OFC system. To embed the ODTD into a free-space optical communication system, we propose a conditional dynamics based Kennedy (CD-Kennedy) receiver combined with the optical combining technique and the diversity technique. We analytically study the error probability of the CD-Kennedy receiver. Numerical results show that both the original Kennedy receiver and the optimized displacement receiver fail in the presence of either turbulence or thermal noise. We show that the proposed CD-Kennedy receiver can outperform the homodyne receiver in either weak turbulence or small thermal noise. At last, we combine the ODTD with the binary modulated continuous variable-quantum key distribution (CV-QKD) based on the post-selection scheme. We derive the secret key rate for a binary modulated CV-QKD using ODTD and post-selection under both individual and collective beamsplitter attacks. We optimize the post selected area and the coherent amplitude for different transmission efficiency of the channel under different thermal noises. Numerical results show that the secret key rate using ODTD can surpass that using the classical coherent detection under different transmission efficiencies and different thermal noises.

description: In the canton of Bern in the 1960s and 1970s, guardianship authorities and schools often turn to the educational counselling service (ECS), the child and adolescent psychiatric service (CAPS) or the Neuhaus children observation center when they notice deviant behavior in children and adolescents. In the assessments carried out by these institutions, the mother often becomes the focus of attention. In this contribution, we reconstruct the different lines of argumentation of the ECS, CAPS, and the Neuhaus in child placement processes: they assess the mothers’ parenting, describe how work-related absences affect the children and adolescents under investigation, or describe mothers who do not cooperate as incompetent. From this perspective, being a mother becomes investigable, assessable and mobilizable – and thus a priori discreditable. Social and psychiatric diagnoses confirm each other and ultimately produce the «neglected» child that is to be placed in a home or a foster family.

Is the decay of the Higgs boson to a photon and a dark photon currently observable at the LHC?

description: Many attempts have been made to observe the decay of the Higgs boson to a photon and an invisible massless dark photon. For this decay to be potentially observable at the LHC, new mediators that communicate between the Standard Model and the dark photon must exist. In this Letter, we study bounds on such mediators coming from the Higgs signal strengths, oblique parameters, electric dipole moment of the electron and unitarity. We find that the branching ratio of the Higgs boson to a photon and a dark photon is constrained to be far smaller than the sensitivity of current collider searches, thus calling for a reconsideration of current experimental efforts.

description: Relationships between the X-ray and radio behavior of black hole X-ray binaries during outbursts have established a fundamental coupling between the accretion disks and radio jets in these systems. We begin by reviewing the prevailing paradigm for this disk-jet coupling, also highlighting what we know about similarities and differences with neutron star and white dwarf binaries. Until recently, this paradigm had not been directly tested with dedicated high-angular resolution radio imaging over entire outbursts. Moreover, such high-resolution monitoring campaigns had not previously targetted outbursts in which the compact object was either a neutron star or a white dwarf. To address this issue, we have embarked on the Jet Acceleration and Collimation Probe Of Transient X-Ray Binaries (JACPOT XRB) project, which aims to use high angular resolution observations to compare disk-jet coupling across the stellar mass scale, with the goal of probing the importance of the depth of the gravitational potential well, the stellar surface and the stellar magnetic field, on jet formation. Our team has recently concluded its first monitoring series, including (E)VLA, VLBA, X-ray, optical, and near-infrared observations of entire outbursts of the black hole candidate H1743-322, the neutron star system Aquila X-1, and the white dwarf system SS Cyg. Here we present preliminary results from this work, largely confirming the current paradigm, but highlighting some intriguing new behavior, and suggesting a possible difference in the jet formation process between neutron star and black hole systems.

description: In recent years, large-scale transformer decoders such as the GPT-x family of models have become increasingly popular. Studies examining the behavior of these models tend to focus only on the output of the language modeling head and avoid analysis of the internal states of the transformer decoder. In this study, we present a collection of methods to analyze the hidden states of GPT-2 and use the model's navigation of garden path sentences as a case study. To enable this, we compile the largest currently available dataset of garden path sentences. We show that Manhattan distances and cosine similarities provide more reliable insights compared to established surprisal methods that analyze next-token probabilities computed by a language modeling head. Using these methods, we find that negating tokens have minimal impacts on the model's representations for unambiguous forms of sentences with ambiguity solely over what the object of a verb is, but have a more substantial impact of representations for unambiguous sentences whose ambiguity would stem from the voice of a verb. Further, we find that analyzing the decoder model's hidden states reveals periods of ambiguity that might conclude in a garden path effect but happen not to, whereas surprisal analyses routinely miss this detail.

description: Following the approach outlined in [26], convergence to SLE$_6$ of the Exploration Processes for the correlated bond-triangular type models studied in [11] is established. This puts the said models in the same universality class as the standard site percolation model on the triangular lattice [27]. In the context of these models, the result is proven for all domains with boundary Minkowski dimension less than two. Moreover, the proof of convergence applies in the context of general critical 2D percolation models and for general domains, under the stipulation that Cardy's Formula can be established for domains in this generality.

description: Most near-term quantum information processing devices will not be capable of implementing quantum error correction and the associated logical quantum gate set. Instead, quantum circuits will be implemented directly using the physical native gate set of the device. These native gates often have a parameterization (e.g., rotation angles) which provide the ability to perform a continuous range of operations. Verification of the correct operation of these gates across the allowable range of parameters is important for gaining confidence in the reliability of these devices. In this work, we demonstrate a procedure for sample-efficient verification of continuously-parameterized quantum gates for small quantum processors of up to approximately 10 qubits. This procedure involves generating random sequences of randomly-parameterized layers of gates chosen from the native gate set of the device, and then stochastically compiling an approximate inverse to this sequence such that executing the full sequence on the device should leave the system near its initial state. We show that fidelity estimates made via this technique have a lower variance than fidelity estimates made via cross-entropy benchmarking. This provides an experimentally-relevant advantage in sample efficiency when estimating the fidelity loss to some desired precision. We describe the experimental realization of this technique using continuously-parameterized quantum gate sets on a trapped-ion quantum processor from Sandia QSCOUT and a superconducting quantum processor from IBM Q, and we demonstrate the sample efficiency advantage of this technique both numerically and experimentally.

description: Il presente lavoro di ricerca vuole indagare in che modo un progetto interdisciplinare condiviso dalla classe possa favorire la collaborazione, le relazioni tra compagni, l’ascolto e la conoscenza reciproci. I bambini e la docente intraprendono un viaggio alla scoperta di sé e delle città immaginarie che permette loro di conoscere meglio sé stessi e gli altri. A gruppi, i ragazzi creano le proprie città e alcuni degli aspetti che le caratterizzano: le descrizioni, gli abitanti, le tradizioni e le culture, le loro specificità, le leggende di come sono state fondate, gli opuscoli turistici e così via. Il percorso, di durata annuale, considera diverse discipline come l’italiano, la geografia e le arti e permette ai bambini di sviluppare molte competenze trasversali. Le osservazioni diaristiche tenute dall’insegnante e le produzioni dei bambini forniscono dei dati qualitativi che permettono di sostenere che un progetto di questo tipo migliora le dinamiche relazionali, favorendo così la collaborazione, l’ascolto e l’aiuto reciproco. Grazie all’attuazione di lavori a gruppi e ad attività sulla narrazione di sé e sulle identità competenti, gli allievi hanno inoltre l’opportunità di approfondire la conoscenza dei compagni e quella personale, dei propri punti di forza e di quelli altrui. Tali aspetti portano i bambini a rivalutare la forza del gruppo-classe e a considerare lo stare insieme come un momento dal quale trarre beneficio. Relatrice: Marina Bernasconi
Constraining the ${\rm\overline{K}N}$ coupled channel dynamics using femtoscopic correlations at the LHC

description: The interaction of $\rm{K}^{-}$ with protons is characterised by the presence of several coupled channels, systems like ${\rm \overline{K}^0}$n and $πΣ$ with a similar mass and the same quantum numbers as the $\rm{K}^{-}$p state. The strengths of these couplings to the $\rm{K}^{-}$p system are of crucial importance for the understanding of the nature of the $Λ(1405)$ resonance and of the attractive $\rm{K}^{-}$p strong interaction. In this article, we present measurements of the $\rm{K}^{-}$p correlation functions in relative momentum space obtained in pp collisions at $\sqrt{s}~=~13$ TeV, in p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}~=~5.02$ TeV, and (semi)peripheral Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}~=~5.02$ TeV. The emitting source size, composed of a core radius anchored to the $\rm{K}^{+}$p correlation and of a resonance halo specific to each particle pair, varies between 1 and 2 fm in these collision systems. The strength and the effects of the ${\rm \overline{K}^0}$n and $πΣ$ inelastic channels on the measured $\rm{K}^{-}$p correlation function are investigated in the different colliding systems by comparing the data with state-of-the-art models of chiral potentials. A novel approach to determine the conversion weights $ω$, necessary to quantify the amount of produced inelastic channels in the correlation function, is presented. In this method, particle yields are estimated from thermal model predictions, and their kinematic distribution from blast-wave fits to measured data. The comparison of chiral potentials to the measured $\rm{K}^{-}$p interaction indicates that, while the $πΣ-\rm{K}^{-}$p dynamics is well reproduced by the model, the coupling to the ${\rm \overline{K}^0}$n channel in the model is currently underestimated.

description: We present a computational protocol, based on density matrix perturbation theory, to obtain non-adiabatic, frequency-dependent electron-phonon self-energies for molecules and solids. Our approach enables the evaluation of electron-phonon interaction using hybrid functionals, for spin-polarized systems, and the computational overhead to include dynamical and non-adiabatic terms in the evaluation of electron-phonon self-energies is negligible. We discuss results for molecules, as well as pristine and defective solids.
Drift waves in the corona: heating and acceleration of ions at frequencies far below the gyro frequency

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: In the solar corona, several mechanisms of the drift wave instability can make the mode growing up to amplitudes at which particle acceleration and stochastic heating by the drift wave take place. The stochastic heating, well known from laboratory plasma physics where it has been confirmed in numerous experiments, has been completely ignored in past studies of coronal heating. However, in the present study and in our very recent works it has been shown that the inhomogeneous coronal plasma is, in fact, a perfect environment for fast growing drift waves. As a matter of fact, the large growth rates are typically of the same order as the plasma frequency. The consequent heating rates may exceed the required values for a sustained coronal heating by several orders of magnitude. Some aspects of these phenomena are investigated here. In particular the analysis of the particle dynamics within the growing wave is compared with the corresponding fluid analysis. While both of them predict the stochastic heating, the threshold for the heating obtained from the single particle analysis is higher. The explanation for this effect is given.

We then propose the usage of nonmonotonic upper probabilities as a tool to derive consistent joint upper probabilities for the contextual hidden variables. Finally, we show that for the extreme example of no error, the GHZ state allows for the definition of a joint upper probability that is consistent with the strong correlations.

Financial incentives for green buildings in Canada : a spatio-temporal analysis
Creators: name: Rana, Anber
Publisher: name: University of British Columbia
Year: 2021

description: Green buildings (GBs) are considered to be a more cost-effective and viable solution than transport and other industry sectors to attain carbon mitigation targets. To promote the large-scale adaptation of GBs, one of the key “on-ground efforts” from the government include the development of appropriate financial incentives (FIs). Keeping in view the diverse scope and scale of FIs, an evaluation of FIs is critically important to increase the rate of construction of GBs and to meet desired mitigation targets. The evaluation of FIs involves consideration of the complex nature of building, stakeholders’ perspectives and spatio-temporal design and economic parameters that are rarely considered in conventional studies. Hence, there is a need for pragmatic decision-making that will help in making FIs planning that is beneficial to all stakeholders. In order to address, this need, the main objective of this research is to develop a decision support framework that can evaluate the effectiveness and efficiency of FIs available for GBs in Canada. This objective was achieved in five distinct steps. First, the research reviewed the existing status of FIs in Canada and the techniques used to evaluate FIs, which helped to identify knowledge gaps and specific research requirements in this area. The second step determined the impact of occupancy profiles of residential buildings on estimating viable energy-saving measures. The third step investigated the effectiveness of available FIs for a range of design and economic parameters. The fourth step evaluated the efficiency of available FIs for single buildings and neighborhoods from private and government perspectives. The last step investigated the environmental impacts of operation strategies of a public building and trade-offs between human health and their implication on eligible FIs. The framework presents realistic impacts of the variability in occupancy, operation, building archetypes, stakeholders perspectives, location and economic parameters on the effectiveness and efficiency of incentive policies. The results obtained have the potential to be used by investors and policymakers to increase GBs and achieve sustainable neighborhoods by providing an evaluation method. The policy recommendations can help design and allocate FIs to areas that will yield the largest benefits for all stakeholders.
Dynamic Singularities in Cooperative Exclusion

description: We investigate cooperative exclusion, in which the particle velocity can be an increasing function of the density. Within a hydrodynamic theory, an initial density upsteps and downsteps can evolve into: (a) shock waves, (b) continuous compression or rarefaction waves, or (c) a mixture of shocks and continuous waves. These unusual phenomena arise because of an inflection point in the current versus density relation. This anomaly leads to a group velocity that can either be an increasing or a decreasing function of the density on either side of these wave singularities.

description: Recent experiment has unveiled an anomalously strong electron-electron attraction in one-dimensional copper-oxide chain Ba$_{2-x}$Sr$_x$CuO$_{3+δ}$. While the near-neighbor electron attraction $V$ in the one-dimensional extended Hubbard chain has been examined recently, its effect in the Hubbard model beyond the one-dimensional chain remains unclear. We report a density-matrix renormalization group study of the extended Hubbard model on long four-leg cylinders on the square lattice. We find that the near-neighbor electron attraction $V$ can notably enhance the long-distance superconducting correlations while simultaneously suppressing the charge-density-wave correlations. Specifically, for a modestly strong electron attraction, the superconducting correlations become dominant over the CDW correlations with a Luttinger exponent $K_{sc}\sim 1$ and strong divergent superconducting susceptibility. Our results provide a promising way to realize long-range superconductivity in the doped Hubbard model in two dimensions. The relevance of our numerical results to cuprate materials is also discussed.

description: The sensitivity of laser interferometers can be pushed into regimes that enable the direct observation of quantum behaviour of mechanical oscillators. In the past, membranes with subwavelength thickness (thin films) have been proposed as high-mechanical-quality, low-thermal-noise oscillators. Thin films from a homogenous material, however, generally show considerable light transmission accompanied by heating due to light absorption, which typically reduces the mechanical quality and limits quantum opto-mechanical experiments in particular at low temperatures. In this work, we experimentally analyze a Michelson-Sagnac interferometer including a translucent silicon nitride (SiN) membrane with subwavelength thickness. We find that such an interferometer provides an operational point being optimally suited for quantum opto-mechanical experiments with translucent oscillators. In case of a balanced beam splitter of the interferometer, the membrane can be placed at a node of the electro-magnetic field, which simultaneously provides lowest absorption and optimum laser noise rejection at the signal port. We compare the optical and mechanical model of our interferometer with experimental data and confirm that the SiN membrane can be coupled to a laser power of the order of one Watt at 1064 nm without significantly degrading the membrane's quality factor of the order 10^6, at room temperature.

description: The behavior of the low-frequency electromagnon in multiferroic DyMnO3 has been investigated in external magnetic fields and in a magnetically ordered state. Significant softening of the electromagnon frequency is observed for external magnetic fields parallel to the a-axis (BIIa), revealing a number of similarities to a classical soft mode behavior known for ferroelectric phase transitions. The softening of the electromagnon yields an increase of the static dielectric permittivity which follows a similar dependence as predicted by the Lyddane-Sachs-Teller relation. Within the geometry BIIb the increase of the electromagnon intensity does not correspond to the softening of the eigenfrequency. In this case the increase of the static dielectric permittivity seem to be governed by the motion of the domain walls.

description: We analyzed the network structure of real-time object detection models and found that the features in the feature concatenation stage are very rich. Applying an attention module here can effectively improve the detection accuracy of the model. However, the commonly used attention module or self-attention module shows poor performance in detection accuracy and inference efficiency. Therefore, we propose a novel self-attention module, called 2D local feature superimposed self-attention, for the feature concatenation stage of the neck network. This self-attention module reflects global features through local features and local receptive fields. We also propose and optimize an efficient decoupled head and AB-OTA, and achieve SOTA results. Average precisions of 49.0% (71FPS, 14ms), 46.1% (85FPS, 11.7ms), and 39.1% (107FPS, 9.3ms) were obtained for large, medium, and small-scale models built using our proposed improvements. Our models exceeded YOLOv5 by 0.8% -- 3.1% in average precision.

Measurement of muon pairs produced via $γγ$ scattering in non-ultraperipheral Pb+Pb collisions at $\sqrt{s_{_\mathrm{NN}}} = 5.02$ TeV with the ATLAS detector

description: Results of a measurement of dimuon photoproduction in non-ultraperipheral Pb+Pb collisions at $\sqrt{s_{_\mathrm{NN}}} = 5.02$ TeV are presented. The measurement uses ATLAS data from the 2015 and 2018 Pb+Pb data-taking periods at the LHC with an integrated luminosity of $1.94~\mathrm{nb}^{-1}$. The $γγ\rightarrow μ^+μ^-$ pairs are identified via selections on pair momentum asymmetry and acoplanarity. Differential cross-sections for dimuon production are measured in different centrality, average muon momentum and pair rapidity intervals as functions of acoplanarity and $k_\perp$, the transverse momentum kick of one muon relative to the other. Measurements are also made as a function of the rapidity separation of the muons and the angle of the muon pair relative to the second-order event plane to test whether magnetic fields generated in the quark-gluon plasma affect the measured muons. A prior observation of a centrality-dependent broadening of the acoplanarity distribution is confirmed. Furthermore, the improved precision of the measurement reveals a depletion in the number of pairs having small acoplanarity or $k_{\perp}$ values in more central collisions. The acoplanarity distributions in a given centrality interval are observed to vary with the mean-$p_{\mathrm{T}}$ of the muons in the pair, but the $k_{\perp}$ distributions do not. Comparisons with recent theoretical predictions are made. The predicted trends associated with effects of magnetic fields on the dimuons are not observed.

description: This paper presents karma mechanisms, a novel approach to the repeated allocation of a scarce resource among competing agents over an infinite time. Examples include deciding which ride hailing trip requests to serve during peak demand, granting the right of way in intersections or lane mergers, or admitting internet content to a regulated fast channel. We study a simplified yet insightful formulation of these problems where at every instant two agents from a large population get randomly matched to compete over the resource. The intuitive interpretation of a karma mechanism is "If I give in now, I will be rewarded in the future." Agents compete in an auction-like setting where they bid units of karma, which circulates directly among them and is self-contained in the system. We demonstrate that this allows a society of self-interested agents to achieve high levels of efficiency without resorting to a (possibly problematic) monetary pricing of the resource. We model karma mechanisms as dynamic population games and guarantee the existence of a stationary Nash equilibrium. We then analyze the performance at the stationary Nash equilibrium numerically. For the case of homogeneous agents, we compare different mechanism design choices, showing that it is possible to achieve an efficient and ex-post fair allocation when the agents are future aware. Finally, we test the robustness against agent heterogeneity and propose remedies to some of the observed phenomena via karma redistribution.
