Looking for an extra dimension with tomographic cosmic shear

Subjects: subject: Astrophysics (astro-ph)

description: The cosmic acceleration was discovered in one of the brane-based models. We are interested in discriminating this model from the dark energy by tomographic cosmic shear. Growth factors are different in the two models when one adjusts parameters to get nearly identical H(z). The two models could be distinguished with independent determinations of both geometrical factors and the growth factor. We introduce new parameterizations to separate the influence of geometry and the influence of growth on cosmic shear maps. We find that future observations will be able to distinguish between both models.

description: The Aubry transition between sliding and pinned phases, driven by the competition between two incommensurate length scales, represents a paradigm that is applicable to a large variety of microscopically distinct systems. Despite previous theoretical studies, it remains an open question to what extent quantum effects modify the transition, or are experimentally observable. An experimental platform that can potentially reach the quantum regime has recently become available in the form of trapped laser-cooled ions subject to a periodic optical potential [A. Bylinskii, D. Gangloff, I. Counts, and V. Vuletic, Nature Materials 15, 717 (2016)]. Using Path-Integral Monte Carlo (PIMC) simulation methods, we analyze the impact of quantum tunneling on the sliding-to-pinned transition in this system, and determine the phase diagram in terms of incommensuration and potential strength. We propose new signatures of the quantum Aubry transition that are robust against thermal and finite-size effects, and that can be observed in future experiments.

Keyframe animation of implicit models
Creators: name: White, David I.
Publisher: name: University of British Columbia
Year: 2010

description: We present an approach that automatically constructs physically plausible in-between frames, given keyframes of arbitrary implicit surface geometry and feature points registered between adjacent keyframes. This extends to usable keyframe control of computer animated fluid-like materials. Most current implicit surface morphs do not allow feature point tracking and none guarantee physically plausible in-between frames of arbitrary motion. Standard triangle surface mesh morphing techniques do not guarantee physically plausible in-betweens either, nor can they handle topological changes. Current fluid control approaches do not respect keyframes nor track feature points. Our variational approach finds a volume mapping between keyframes which minimizes a physics-based objective function using Gauss-Newton modified to handle linear constraints. We then create as-rigid-as-possible trajectories of the volume respecting this map, which we use to create physically plausible in-between frames.

description: We study classical integrability of the supersymmetric U(N) $σ$ model with the Wess-Zumino-Witten term on full and half plane. We demonstrate the existence of nonlocal conserved currents of the model and derive general recursion relations for the infinite number of the corresponding charges in a superfield framework. The explicit form of the first few supersymmetric charges are constructed. We show that the considered model is integrable on full plane as a concequence of the conservation of the supersymmetric charges. Also, we study the model on half plane with free boundary, and examine the conservation of the supersymmetric charges on half plane and find that they are conserved as a result of the equations of motion and the free boundary condition. As a result, the model on half plane with free boundary is integrable. Finally, we conclude the paper and some features and comments are presented.

description: Several levels of the Lorraine Group (Upper Ordovician) in upstate New York (USA) have yielded low-diversity, exceptionally preserved, pyritized invertebrate assemblages dominated by the trilobite Triarthrus eatoni. Sedimentological and taphonomic features suggest dysoxic bottom-water conditions, with limited transport and rapid burial by distal turbidites. Echinoderms are extremely rare in these strata. Here we report, for the first time, the occurrence of the anomalocystitid mitrate Enoploura popei in the Konservat-Lagerstätte of Beecher's Trilobite Bed. A pyritized specimen of this stylophoran was CT-scanned and three-dimensionally reconstructed. The mitrate is laterally compressed, but its 3D-rendering provided several insights into its internal anatomy and taphonomy. The recurved position of the single feeding appendage (aulacophore) is consistent with ligament-induced, post mortem contraction. This posture and the collapse of one lateral series of cover plates indicate that the individual was probably not buried alive. Nevertheless, a portion of the distal aulacophore shows clear evidence of exceptionally preserved soft parts (ambulacral system) in between two sets of slightly open cover plates and the underlying ossicles. One of the most intriguing features of this specimen is its close association with a sinuous, elongated, pyritized trace fossil, which enters the stylophoran through the mouth and disappears into the proximal aulacophore. In marked contrast with other skeletal parts of the specimen (theca and distal part of the aulacophore), the proximal rings of the aulacophore are heavily disrupted and disarticulated. Proximal rings are usually decay-resistant skeletal regions in stylophorans. Therefore, close association of this disrupted region with a trace fossil penetrating it suggests the action of an unknown infaunal scavenger. Location of this trace suggests targeting during early decay of the large muscular proximal aulacophore.

description: Biologically-informed neural networks (BINNs), an extension of physics-informed neural networks [1], are introduced and used to discover the underlying dynamics of biological systems from sparse experimental data. In the present work, BINNs are trained in a supervised learning framework to approximate in vitro cell biology assay experiments while respecting a generalized form of the governing reaction-diffusion partial differential equation (PDE). By allowing the diffusion and reaction terms to be multilayer perceptrons (MLPs), the nonlinear forms of these terms can be learned while simultaneously converging to the solution of the governing PDE. Further, the trained MLPs are used to guide the selection of biologically interpretable mechanistic forms of the PDE terms which provides new insights into the biological and physical mechanisms that govern the dynamics of the observed system. The method is evaluated on sparse real-world data from wound healing assays with varying initial cell densities [2].

description: Neocrinus goedertorum sp. nov., an exceptionally well preserved, small-sized crinoid of the family Balanocrinidae, was found from the late Eocene to Oligocene Makah Formation, on the northern shore of the Olympic Peninsula in Washington State, USA. The specimen of the new species possesses ten arms, and is characterized by synarthrial articulation in the primibrachials, and embayed synarthrial and symmorphial articulation in the proximal secundibrachials. These characters lead to its assignment to the balanocrinid genus Neocrinus that is now widely distributed from the bathyal depths of western Pacific as well as in the western Atlantic. The present discovery extends the stratigraphic record of the genus Neocrinus at least to the Oligocene.

description: Sea urchins in the genus Tripneustes have fast growth and population density fluctuations. In New South Wales (NSW) Australia and New Zealand, the endemic species T. australiae occurs in the subtropical to temperate regions on rocky reefs and seagrass meadows. In aggregations, T. australiae can strip these habitats of macroalgae and seagrass. We used Reef Life Survey data to follow the density of T. australiae from 2008 to 2024 at three locations, Solitary Islands (30°S), Sydney (33.8°S) and Jervis Bay (35°S). In these surveys, T. australiae was most common at the Solitary Islands in subtropical northern NSW and declined in density poleward. Numbers of T. australiae were low at Jervis Bay near its cold range edge. At the Solitary Islands and Sydney, T. australiae appeared in conspicuous numbers followed by decrease on an approximate decadal scale. In Sydney the density of T. australiae increased following mass mortality of resident sea urchins during the 2022 floods. At present, T. australiae appears to be undergoing range extension and in 2024 became conspicuous in southern NSW, as far south as Narooma (36°S). Targeted surveys at six locations from the Solitary Islands to Narooma revealed what appears to be the presence of several cohorts of T. australiae, indicating pulses of recruitment.The drivers of the population dynamics of T. australiae are likely to be related to climate and other factors and are important to understand.

The topics covered are largely focused on active galactic nuclei (AGN) and include (1) the selection of AGN via X-ray emission and optical variability, (2) nuclear outbursts in galaxies due to transient fueling of their supermassive black holes, (3) moderate-luminosity AGN at high redshift (z > 4) found via application of "dropout" techniques to X-ray sources, and (4) the host-galaxy morphologies of X-ray selected AGN. I also describe the substantial challenges to obtaining wide-field X-ray data with sufficient sensitivity to complement JDEM properly.

description: The integument of sea cucumbers is known for its interesting nutritional value due to its high protein composition and low lipid content. In Algeria, studies have been carried out on the fresh integument of several species of sea cucumbers. This study builds on previous findings by analyzing the nutritional composition and pepsin digestibility of the dried product "bêche-de-mer" from five sea cucumber species collected in the Mostaganem region. The dry product was then used for culinary purposes by preparing two popular dishes commonly consumed in Maghrebi cuisine ("minced sea cucumber-based sausage" and "sea cucumber bourek"). A tasting session was carried out on a sample of the population of the Mostaganem region in order to have an idea of the quality of each prepared dish. The estimated nutritional content showed lipid levels ranging from 1.7 to 3.3%, protein levels ranging from 47.9% to 69.6% and ash levels varying from 38.7 to 57.7%. The positive reactions from the majority of participants in the tasting survey encourage the exploration of sea cucumbers, which are not traditionally part of our culinary practices.

description: Sea cucumbers have been harvested and consumed by Chinese and other Asian populations for a thousand years. Fisheries captures to service Asian seafood markets progressively extended to countries in the tropical Pacific, then the Indian Ocean and more recently to the rest of the world. The tropical fisheries are mostly artisanal and multi-species focused, while temperate ones focus on fewer species and are more industrialized. The number of exploited species has increased greatly in recent decades to reach more than 80. Fisheries have often followed a 'boom-and-bust' cycle. Illegal, unreported and unregulated (IUU) harvesting is widespread, especially in low-income countries. Some of the highly sought-after species have been overfished to critically low densities in many localities. Conservation issues have increasingly been raised and research developed on holothuroids, both at the species level, on taxonomy, biology and ecology and at the ecosystem level, on biodiversity, fisheries, aquaculture and markets. Advances in conservation are being facilitated by the efforts of international bodies, including FAO, CITES, IUCN, as well as regional ones such as SPC and WIOMSA, and national research and fisheries administrations across the globe. Many knowledge gaps remain regarding maintaining and restoring sea cucumber population resilience, the data and information gaps, regions of interest and species at risk. Here, we propose research and steps that might help to refine and put in action the processes / instruments necessary for better conservation.

description: Pretrained contextualized language models such as BERT have achieved impressive results on various natural language processing benchmarks. Benefiting from multiple pretraining tasks and large scale training corpora, pretrained models can capture complex syntactic word relations. In this paper, we use the deep contextualized language model BERT for the task of ad hoc table retrieval. We investigate how to encode table content considering the table structure and input length limit of BERT. We also propose an approach that incorporates features from prior literature on table retrieval and jointly trains them with BERT. In experiments on public datasets, we show that our best approach can outperform the previous state-of-the-art method and BERT baselines with a large margin under different evaluation metrics.

description: Sea urchin (Echinodermata: Echinoidea) teeth mineralize in two stages. The first-stage mineral consists of arrays of curving plates of different types and of elongated structures termed needles when they have smaller diameters and prisms when their diameters increase. Then, second-stage mineral cements the plates and needle/prisms together. This paper reports novel high-resolution synchrotron microComputed Tomography (microCT) data of teeth from three species of Odontophora, a taxon of multiple, shallow-water echinoid species. The reconstructed volume elements (voxels) are smaller than 1.3 µm, and this permits the first accurate, threedimensional quantification of plate thicknesses and of needle/prism diameters in sea urchin teeth. Measurements for species within the three odontophoran families Toxopneustidae, Echinometridae, and Strongylocentrotidae are reported, specifically, mean values and their standard deviations; the main focus, however, is on the spatial variation of thickness within single carinar process plates and of diameter along selected prisms' lengths. Possible functional consequences of variation of these structures are examined qualitatively. Finally, prospects for extending the study to higher resolutions are discussed.

description: The two main approaches in interpreting the significance of non-radial fossil echinoderms (carpoids) have consistently produced the same two distinct clusters of results for over a century of investigation. Studies based on conceptual models imbued with Haeckelian precepts consider bilaterally symmetric or asymmetric morphologies of carpoids plesiomorphic for the phylum. These approaches do not find a place for carpoids within an existing phylogenetic framework for the phylum because it is assumed that they primitively lack pentaradiality. Emphasis on differences between these taxa and pentaradial echinoderms forces them outside of and downward from more crownward clades. It is crucial to examine the data supporting these supposed differences. Is it worth considering non-pentaradial echinoderms as members of a well-known group of echinoderms, the blastozoans, which already includes many secondarily-derived, non-pentaradial members? Followers of an empirical model think so, presenting an integration of paleontology, embryology, body wall homology, and image analysis that derives echinoderms from a bilaterian, archimeric larva, not bilateral adults. Unprecedented modification of a single mesocoel (hydrocoel) initiated the pentaradial adult echinoderm, most parsimoniously with five primary lobes in stem forms of each major clade within the phylum. The unique water vascular system led to rearrangement of adult axes that literally have no parallel with those of any other invertebrate, representing an iconic synapomorphy for the Echinodermata. There are few, if any, developmental or stratigraphic data defending carpoids as 'bilateral precursors'. Their free appendage is now shown to be an ambulacrum, undermining any supposition of a 'head', 'tail', or 'gill slits'. Pentaradiality is plesiomorphic for the phylum, obviating the requirement for a triradial intermediate (helicoplacoids) between carpoids and pentaradial forms. Carpoids, a subset of blastozoans, exploited motility as a feeding mode, leading to extraordinary

description: The giant HII region 30 Doradus is known for its violent internal motions and bright diffuse X-ray emission, suggesting the existence of supernova remnants (SNRs), but no nonthermal radio emission has been detected. Recently, Lazendic et al. compared the H-alpha/H-beta and radio/H-alpha ratios and suggested two small radio sources to be nonthermal and thus SNR candidates; however, no optical or X-ray counterparts were detected. We have used high-resolution optical images and high-dispersion spectra to examine the morphological, spectral, and kinematic properties of these two SNR candidates, and still find no optical evidence supporting their identification as SNRs. We have also determined the X-ray luminosities of these SNR candidates, and find them 1-3 orders of magnitude lower than those commonly seen in young SNRs. High extinction can obscure optical and X-ray signatures of an SNR, but would prohibit the use of a high radio/H-alpha ratio to identify nonthermal radio emission. We suggest that the SNR candidate MCRX J053831.8-690620 is associated with a young star forming region; while the radio emission originates from the obscured star forming region, the observed optical emission is dominated by the foreground. We suggest that the SNR candidate MCRX J053838.8-690730 is associated with a dust/molecular cloud, which obscures some optical emission but not the radio emission.

description: We compare the performance of a quantum radar based on two-mode squeezed states with a classical radar system based on correlated thermal noise. With a constraint of equal number of photons $N_S$ transmitted to probe the environment, we find that the quantum setup exhibits an advantage with respect to its classical counterpart of $\sqrt{2}$ in the cross-mode correlations. Amplification of the signal and the idler is considered at different stages of the protocol, showing that no quantum advantage is achievable when a large-enough gain is applied, even when quantum-limited amplifiers are available. We also characterize the minimal type-II error probability decay, given a constraint on the type-I error probability, and find that the optimal decay rate of the type-II error probability in the quantum setup is $\ln(1+1/N_S)$ larger than the optimal classical setup, in the $N_S\ll1$ regime. In addition, we consider the Receiver Operating Characteristic (ROC) curves for the scenario when the idler and the received signal are measured separately, showing that no quantum advantage is present in this case. Our work characterizes the trade-off between quantum correlations and noise in quantum radar systems.
The sea cucumbers of the Algerian coastal waters: an overview of their taxonomy, ecology, the nascent fisheries and illegal trade

description: The present work aims to provide an overview of the various studies carried out on commercially important sea cucumbers species in the Algerian coastal areas. Herein, we present the taxonomic contribution related to the revision of some species of the Holothuriida, Synallactida and Dendrochirotida orders. Concerning the biology and ecology field, studies have focused on: 1) biometrics, growth and population dynamics; 2) the reproduction of Holothuria (Platyperona) sanctori Delle Chiaje, 1823, Holothuria (Roweothuria) poli Delle Chiaje, 1824, and Holothuria (Holothuria) tubulosa Gmelin, 1791 and 3) the feeding behavior and the analysis of the digestive contents of some species belonging to the genus Holothuria [Holothuria (R.) poli, H. (H.) tubulosa, H. (P.) sanctori and H. (P.) forskali] and Parastichopus (Parastichopus regalis). All these obtained data could be used for the sea cucumbers fisheries that are poorly managed. In fact, in Algeria the harvesting of sea cucumbers is growing rapidly and is capable of extracting significant amounts of these benthic animals. Hence, there is an urgent need for effective management in order to avoid the destruction of the sea cucumbers stock.

This leads to the classification of multiple Taft algebras as well as pointed Yetter-Drinfeld modules and their corresponding Nichols algebras. In particular, when the ground-field $k$ is the complex field and $G$ is a finite abelian group, we classify quiver Hopf algebras over $G$, multiple Taft algebras over $G$ and Nichols algebras in $^{kG}_{kG} {\cal YD}$. We show that the quantum enveloping algebra of a complex semisimple Lie algebra is a quotient of a semi-path Hopf algebra.

description: We calculate the tree-level open-string amplitudes for the scattering of four massless particles with diphoton final states. These amplitudes are required to reproduce those of standard model at the tree level in the low energy limit. After low energy stringy corrections, we found that they have similar form to the same processes induced by exchange of the Kaluza-Klein(KK) excitations of graviton in ADD scenario. Using this similarity, we apply constraints on the KK mass scale $M_D$ to the string scale $M_S$. The results are consistent with constraints from the 4-fermion scattering, about $0.6-0.9$ TeV.

description: We investigate the relationships between water quality and socioeconomic factors in California at the county level for the years 1993 to 2006 using 24 water quality indicators coming from seven different types of water bodies. We estimate these relationships using three classes of models: the traditional per capita income-pollution level - Environmental Kuznets Curve (EKC) - specifications, a more inclusive model containing main socioeconomic variables such as agricultural intensity, land use, ethnic composition, population density and educational attainment, and a model that includes the socioeconomic variables while accounting for spatial correlations too. For most water quality indicators, we do not find support for EKC specifications. For pollutants like phosphorus and total suspended solids, the level of agricultural activity is a significant determinant of water quality in California, but for other surface water pollutants commonly considered agricultural pollutants, such as ammonia and nitrate, the level of agricultural activity is not statistically significant. We find that education, ethnic composition, age structure, land use, population density, and water area are all significantly correlated with various indicators of water quality.

description: The cosmological magnetic field is one of the important physical quantities which affect strongly the cosmic microwave background (CMB) power spectrum. Recent CMB observations have been extended to higher multipoles $l\gtrsim$1000, and they resultantly exhibit an excess power than the standard model prediction in cosmological theory which best fits the Wilkinson Microwave Anisotropy Probe (WMAP) data at lower multipoles $l\lesssim$900. We calculate the CMB temperature anisotropies generated by the power-law magnetic field at the last scattering surface (LSS) in order to remove the tension between theory and observation at higher multipoles and also place an upper limit on primordial magnetic field. In our present calculation we take account of the effect of ionization ratio exactly without approximation. This effect is very crucial to precisely estimate the effect of the magnetic field on CMB power spectrum. We consider both effects of the scalar and vector modes of magnetic field on the CMB anisotropies, where current data are known to be insensitive to the tensor mode which we ignore in the present study. In order to constrain the primordial magnetic field, we evaluate likelihood function of the WMAP data in a wide range of parameters of the magnetic field strength $|\mathbf{B}|_λ$ and the power-law spectral index $n$, along with six cosmological parameters in flat Universe models, using the technique of the Markov Chain Monte Carlo(MCMC) method. We find that the upper limit at $2σ$ C.L. turns out to be $|\mathbf{B}_λ|\lesssim 3.9 $nG at 1 Mpc for any $n_B$ values, which is obtained by comparing the calculated result including the Sunyaev-Zeldovich(SZ) effect with recent WMAP data of the CMB anisotropies.

description: We show that the core of each strongly size monotonic hedonic game is not empty and is externally stable. This is in sharp contrast to other sufficient conditions for core non-emptiness which do not even guarantee the existence of a stable set in such games.

description: Additional file 2. Development of the letrozole-resistant MCF7LR tumors in vivo. a For the development of letrozole-resistant tumors, xenografted MCF7AC1 tumors were chronically exposed to letrozole therapy. At 25 weeks, a subset of tumor-bearing mice in the letrozole group (n = 9) developed resistance to letrozole therapy in vivo. At 27 weeks, letrozole-resistant (MCF7LR) mice were randomized to tamoxifen (n = 4) or Z-endoxifen (n = 5) treatments. Data are presented as mean ± SEM. b Dotplot displaying the baseline-adjusted area under the tumor volume curve for the MCF7LR tumor-bearing mice randomized to Z-endoxifen or tamoxifen treatments.

BRDF acquisition with basis illumination
Creators: name: Achutha, Shruthi
Publisher: name: University of British Columbia

description: To create a realistic image we need to characterize how light reflects off a surface. In optics terminology, the complete Bidirectional Reflectance Distribution Function is needed. At a given point on a surface the BRDF is a function of two directions, one toward the light and one toward the viewer. Any device for measuring the 4D reflectance data has to obtain measurements over the hemisphere of incident and exitant directions which can be quite tedious if done using the brute-force approach. In this thesis, we describe an efficient image-based acquisition setup that has no moving parts and can acquire reflectance data in a matter of a few minutes. We make this possible by using curved reflective surfaces that eliminate the need to move either the camera or the light source. The acquisition speedup mostly comes from the way we optically sample the BRDF data into a suitable basis. This also saves us the post-process compression of data. We then encode the data into a compact form that is suitable for use in various rendering systems.
Status of chiral doublers of heavy-light hadrons in light of recent BaBar Cleo, Belle and Selex D_s states

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We explain the main idea of the chiral doublers scenario, originating from simultaneous constraints of chiral symmetry and of heavy quark spin symmetry on effective theories of heavy-light hadrons. In particular we discuss chiral doublers for mesons, chiral doublers for excited mesons, chiral doublers for baryons and chiral doublers for excited baryons. We point out the arguments why new states D_s(2317) and D_s(2457) might be viewed as chiral doublers of D_s and D_s^*. Then we comment on non-strange mesons D_0(2308) and D_1'(2427) observed by Belle and Focus, and on Theta_c(3099) signal observed by H1. Finally, we point out that very recent discovery by SELEX of D_s(2632), if confirmed by other experiments and if spin-parity of this state is 1^-, may be interpreted as a signal for chiral doubler of D_{s1}(2536). Such an identification implies another narrow, spin-parity 2^- D_s state ca 37 MeV above the new 1^-, corresponding to chiral partner of D_{s2}.

description: We estimate the causal effect of immigrants' legal status on criminal behavior exploiting exogenous variation in migration restrictions across nationalities driven by the last round of the European Union enlargement. Unique individual-level data on a collective clemency bill enacted in Italy five months before the enlargement allow us to compare the post-release criminal record of inmates from new EU member countries with a control group of pardoned inmates from candidate EU member countries. Difference-in-differences in the probability of re-arrest between the two groups before and after the enlargement show that obtaining legal status lowers the recidivism of economically motivated offenders, but only in areas that provide relatively better labor market opportunities to legal immigrants. We provide a search-theoretic model of criminal behavior that is consistent with these results.
Means of a Dirichlet process and multiple hypergeometric functions

description: The Lauricella theory of multiple hypergeometric functions is used to shed some light on certain distributional properties of the mean of a Dirichlet process. This approach leads to several results, which are illustrated here. Among these are a new and more direct procedure for determining the exact form of the distribution of the mean, a correspondence between the distribution of the mean and the parameter of a Dirichlet process, a characterization of the family of Cauchy distributions as the set of the fixed points of this correspondence, and an extension of the Markov-Krein identity. Moreover, an expression of the characteristic function of the mean of a Dirichlet process is obtained by resorting to an integral representation of a confluent form of the fourth Lauricella function. This expression is then employed to prove that the distribution of the mean of a Dirichlet process is symmetric if and only if the parameter of the process is symmetric, and to provide a new expression of the moment generating function of the variance of a Dirichlet process.

description: We investigate two classes of quantum control problems by using frequency-domain optimization algorithms in the context of ultrafast laser control of quantum systems. In the first class, the system model is known and a frequency-domain gradient-based optimization algorithm is applied to searching for an optimal control field to selectively and robustly manipulate the population transfer in atomic Rubidium. The other class of quantum control problems involves an experimental system with an unknown model. In the case, we introduce a differential evolution algorithm with a mixed strategy to search for optimal control fields and demonstrate the capability in an ultrafast laser control experiment for the fragmentation of Pr(hfac)$_3$ molecules.

description: Today's quantum computers are comprised of tens of qubits interacting with each other and the environment in increasingly complex networks. In order to achieve the best possible performance when operating such systems, it is necessary to have accurate knowledge of all parameters in the quantum computer Hamiltonian. In this article, we demonstrate theoretically and experimentally a method to efficiently learn the parameters of resonant interactions for quantum computers consisting of frequency-tunable superconducting qubits. Such interactions include, for example, those to other qubits, resonators, two-level state defects, or other unwanted modes. Our method is based on a significantly improved swap spectroscopy calibration and consists of an offline data collection algorithm, followed by an online Bayesian learning algorithm. The purpose of the offline algorithm is to detect and roughly estimate resonant interactions from a state of zero knowledge. It produces a square-root reduction in the number of measurements. The online algorithm subsequently refines the estimate of the parameters to comparable accuracy as traditional swap spectroscopy calibration, but in constant time. We perform an experiment implementing our technique with a superconducting qubit. By combining both algorithms, we observe a reduction of the calibration time by one order of magnitude. We believe the method investigated will improve present medium-scale superconducting quantum computers and will also scale up to larger systems. Finally, the two algorithms presented here can be readily adopted by communities working on different physical implementations of quantum computing architectures.

A set of moves for Johansson representation of 3-manifolds. An outline

description: A Dehn sphere in a closed 3-manifold M is a 2-sphere immersed in M with only double curve and triple point singularities. The Dehn sphere S fills M if it defines a cell-decomposition of M. The inverse image in S^{2} of the double curves of S is the Johansson diagram of S and if S fills M it is possible to reconstruct M from the diagram. A Johansson representation of M is the Johansson diagram of a filling Dehn sphere of M. In a recent paper of J. M. Montesinos it is proved that every closed 3-manifold has a Johansson representation coming from a nulhomotopic filling Dehn sphere. In this paper a set of moves for Johansson representations of 3-manifolds is given. In a forthcoming paper it is proved that this set of moves suffices for relating different Johansson representations of the same 3-manifold coming from nulhomotopic filling Dehn spheres. The proof of this result is outlined here.
