Chaos of a Markov operator and the fourth moment condition

description: We analyze from the viewpoint of an abstract Markov operator recent results by Nualart and Peccati, and Nourdin and Peccati, on the fourth moment as a condition on a Wiener chaos to have a distribution close to Gaussian. In particular, we are led to introduce a notion of chaos associated to a Markov operator through its iterated gradients and present conditions on the (pure) point spectrum for a sequence of chaos eigenfunctions to converge to a Gaussian distribution. Convergence to gamma distributions may be examined similarly.

description: We propose a technique for performing quantum state tomography of photonic polarization-encoded multi-qubit states. Our method uses a single rotating wave plate, a polarizing beam splitter and two photon-counting detectors per photon mode. As the wave plate rotates, the photon counters measure a pseudo-continuous signal which is then Fourier transformed. The density matrix of the state is reconstructed using the relationship between the Fourier coefficients of the signal and the Stokes' parameters that represent the state. The experimental complexity, i.e. different wave plate rotation frequencies, scales linearly with the number of qubits.

description: We study images of the unit ball under certain special classes of quasiregular mappings. For homeomorphic, i.e., quasiconformal mappings problems of this type have been studied extensively in the literature. In this paper we also consider non-homeomorphic quasiregular mappings. In particular, we study (topologically) closed quasiregular mappings originating from the work of J. Väisälä and M. Vuorinen in 1970's. Such mappings need not be one-to-one but they still share many properties of quasiconformal mappings. The global behavior of closed quasiregular mappings is similar to the local behavior of quasiregular mappings restricted to a so-called normal domain.

description: We compare the locations of 82 X-ray binaries (XRBs) detected in the merging Antennae galaxies by Zezas et al., based on observations taken with the Chandra X-Ray Observatory, with a catalog of optically selected star clusters presented by Whitmore et al., based on observations taken with the Hubble Space Telescope. Within the 2 sigma positional uncertainty of 0.58", we find 22 XRBs are coincident with star clusters, where only 2-3 chance coincidences are expected. The ages of the clusters were estimated by comparing their UBVI, Halpha colors with predictions from stellar evolutionary models. We find that 14 of the 22 coincident XRBs (64%) are hosted by star clusters with ages of 6 Myr or less. Five of the XRBs are hosted by young clusters with ages 10-100 Myr, while three are hosted by intermediate age clusters with 100-300 Myr. Based on the results from recent N-body simulations, which suggest that black holes are far more likely to be retained within their parent clusters than neutron stars, we suggest that our sample consists primarily of black hole binaries with different ages.

description: Mindful parenting and parenting cognitions likely have important linkages to each other and to parent-child communication, but these linkages have not been tested. In this article, we test the bidirectional linkages between mindful parenting and parenting cognitions (sense of competence, parent-centered attributions) and the underlying mediational processes that link them to parent-child communication (parental solicitation and youth disclosure). Longitudinal, autoregressive cross-lagged models were run within a longitudinal sample of rural and suburban early adolescents and their mothers (n = 421; mean adolescent age = 12.14, 46% male, 73% white). Significant bidirectional linkages were found between mindful parenting and parenting cognitions across Time 1 and Time 2. Greater mindful parenting at Time 1 was associated with more positive parenting cognitions (e.g., greater perceptions of parental competence and fewer negative parent-centered attributions or self-blame) at Time 2. More positive parenting cognitions at Time 1 were also associated with greater levels of mindful parenting at Time 2. Mindful parenting at Time 2 mediated the association between parenting cognitions (both parent-centered attributions and sense of competence) at Time 1 and parental solicitation at Time 3. Mindful parenting and parenting cognitions influence each other over time. Parenting cognitions can affect parental solicitation via increases in mindful parenting. The discussion focuses on potential underlying processes.

description: The Alaska Region of the US Fish and Wildlife Service began a requirements analysis for a regional data management system in early 2020. A needs assessment was completed in January 2021 to identify mandatory requirements and better understand staff needs and desired features (https://doi.org/10.7944/P9T1UDMY). This report built upon that assessment by providing a system suitability analysis. System requirements and needs and wants of the staff were categorized and placed in a Quality Function Deployment (QFD) Model, along with the most common systems used by staff and several options in use by other DOI and Federal agencies. Overall, modular systems that have been purpose-built to manage the life cycle of data scored highest and appear to be the most adaptive in meeting staff wants and needs beyond core requirements. Systems emerged in several groupings; those currently in use today, open-source modular systems, third-party subscriber platforms, and outsourced solutions.

description: Sensors that harness exclusively quantum phenomena (such as entanglement) can achieve superior performance compared to those employing only classical principles. Recently, a technique based on postselected, weakly-performed measurements has emerged as a method of overcoming technical noise in the detection and estimation of small interaction parameters, particularly in optical systems. The question of which other types of noise may be combatted remains open. We here analyze whether the effect can overcome decoherence in a typical field sensing scenario. Benchmarking a weak, postselected measurement strategy against a strong, direct strategy we conclude that no advantage is achievable, and that even a small amount of decoherence proves catastrophic to the weak-value amplification technique.

description: We will investigate the norm closure of the unitary and similarity orbits of normal operators in unital, simple, purely infinite C*-algebras. An operator theoretic proof will be given to the classification of when two normal operators are approximately unitarily equivalent in said algebras with trivial K_1-group. Some upper and lower bounds for the distance between unitary orbits will be obtained based on these methods. In addition, a complete characterization of when one normal operator is in the closed similarity orbit of another normal operator will be given for unital, simple, purely infinite C*-algebras and type III factors with separable predual.

description: Additional file 7. The combination does not affect autophagic flux in glioblastoma cells. NCH82 cells were treated with 48 µM temozolomide (TMZ) combined with 2.66 µM SKI-II (TMZ+SKI-II) in the presence and absence of 100 nM Bafilomycin A1 (BA1) under 21% O2 and 3% O2. (A, B) Cell extracts were separated on SDS- PAGE and transferred on nitrocellulose membrane. DMSO and (TMZ+SKI-II) gels were run in parallel. Representative blots are shown. The expression levels of p62 (Ai, Bi) and LC3-II (Aii, Bii) were quantified and normalized to GAPDH. Autophagic flux under basal conditions (DMSO) and under treatment (TMZ + SKI-II) was determined by the subtraction of LC3-II levels without BA1 (Ctrl) from LC3-II levels with BA1 (Aiii, Biii). LC3-II (n = 3); p62 (n = 2). The results are shown as mean (±SD). Two-way ANOVA followed by Tukey’s multiple comparisons test was performed for statistical analysis.

description: We demonstrate that thousands of periodic nano-craters are fabricated on a subwavelength-diameter tapered optical fiber, an optical nanofiber, by irradiating with just a single femtosecond laser pulse. A key aspect of the fabrication is that the nanofiber itself acts as a cylindrical lens and focuses the femtosecond laser beam on its shadow surface. We also demonstrate that such periodic structures on the nanofiber, act as a 1-D photonic crystal (PhC). Such PhC structures on the nanofiber will strongly enhance the field confinement in such a tapered fiber-based system and may open new avenues in nanophotonics and quantum information technology.

description: We propose a novel scheme for probabilistic teleportation when the information of the partially entangled state is only available for the sender. This is in contrast with the fact that the receiver must know the non-maximally entangled state in previous typical schemes for the teleportation. Additionally, we illustrate two potential applications of the novel scheme to probabilistically teleport an unknown two-level quantum state from a sender to a receiver with the help of an assistant, who plays distinguishable roles under different communication conditions, and the applications indicate that our proposal could improve the security and enlarge the applied range of probabilistic teleportation.

description: We demonstrate that in the supersymmetric extensions of a class of generalized (or K) field theories introduced recently, the static energy satisfies a BPS bound in each topological sector. Further, the corresponding soliton solutions saturate the bound. We also find strong indications that the BPS bound shows up in the SUSY algebra as a central extension, as is the case in the well-known supersymmetric field theories with standard kinetic terms.

description: The Alaska Region of the US Fish and Wildlife Service began a requirements analysis for a regional data management system in early 2020. A needs assessment was completed to identify mandatory requirements and better understand staff needs and desired features. The needs assessment aimed to understand: 1) current data management practices of staff; 2) quantity and format of the data staff produce; 3) where data are stored; 4) data management challenges; and 5) desired features that staff would like to have incorporated into a future system. Staff who work with scientific data in the Alaska Region were given the opportunity to complete a questionnaire and participate in individual interviews regarding their data management practices. Supervisors and staff in other leadership roles were also interviewed. Staff expressed a desire for a regional data management system that is easy to use and improves efficacy. Commonly requested features among staff were the ability for dynamic searching, enhanced analytics, and options for data visualization. Staff and leadership desired the ability to track projects and major milestones. Desired attributes were classified into system requirements, needs and wants. The needs assessment also revealed numerous opportunities for improvements related to data governance. The second phase of this project was a systems suitability analysis, completed in July 2021 (https://doi.org/10.7944/P9VDJSON).

description: Exact results of pair transfer probabilities for the Richardson model with equidistant or random level spacing are presented. The results are then compared either to particle-particle random phase approximation (ppRPA) in the normal phase or quasi-particle random phase approximation (QRPA) in the superfluid phase. We show that both ppRPA and QRPA are globally well reproducing the exact case although some differences are seen in the superfluid case. In particular the QRPA overestimates the pair transfer probabilities to excited states in the vicinity of the normal-superfluid phase transition, which might explain the difficult in detecting collective pairing phenomena as for example the Giant Pairing Vibration. The shortcoming of QRPA can be traced back to the breaking of particle number that is used to incorporate pairing. A method, based on direct diagonalization of the Hamiltonian in the space of two quasi-particle projected onto good particle number is shown to improve the description of pair transfer probabilities in superfluid systems.

description: Simulations based on experimental data obtained from multifragmenting quasifused nuclei produced in central 129Xe + natSn collisions have been used to deduce event by event freeze-out properties on the thermal excitation energy range 4-12 AMeV. From these properties and temperatures deduced from proton transverse momentum fluctuations constrained caloric curves have been built. At constant average volumes caloric curves exhibit a monotonous behaviour whereas for constrained pressures a backbending is observed. Such results support the existence of a first order phase transition for hot nuclei.

Dynamics of stellar black holes in young star clusters with different metallicities - I. Implications for X-ray binaries

description: We present N-body simulations of intermediate-mass (3000-4000 Msun) young star clusters (SCs) with three different metallicities (Z=0.01, 0.1 and 1 Zsun), including metal-dependent stellar evolution recipes and binary evolution. Following recent theoretical models of wind mass loss and core collapse supernovae, we assume that the mass of the stellar remnants depends on the metallicity of the progenitor stars. In particular, massive metal-poor stars (Z<=0.3 Zsun) are enabled to form massive stellar black holes (MSBHs, with mass >=25 Msun) through direct collapse. We find that three-body encounters, and especially dynamical exchanges, dominate the evolution of the MSBHs formed in our simulations. In SCs with Z=0.01 and 0.1 Zsun, about 75 per cent of simulated MSBHs form from single stars and become members of binaries through dynamical exchanges in the first 100 Myr of the SC life. This is a factor of >~3 more efficient than in the case of low-mass (<25 Msun) stellar black holes. A small but non-negligible fraction of MSBHs power wind-accreting (10-20 per cent) and Roche lobe overflow (RLO, 5-10 per cent) binary systems. The vast majority of MSBH binaries that undergo wind accretion and/or RLO were born from dynamical exchange. This result indicates that MSBHs can power X-ray binaries in low-metallicity young SCs, and is very promising to explain the association of many ultraluminous X-ray sources with low-metallicity and actively star forming environments.
