description: We provide a schematic framework for understanding observations of jet suppression in soft state black hole X-ray binaries based on the Blandford-Payne process and the net magnetic flux threading the black hole. Due to the geometrical thinness of soft state disks, mass-loading of field lines is ineffective compared to both geometrically thick disks as well as thin disks with greater black hole threading flux, a simple physical picture that allows us to understand the weakness of jets in radiatively efficient thin disks accreting in the prograde direction around high-spinning black holes. Despite a simplicity that forbids insights into the complexity of turbulent-driven evolution or the physics of the observed short-term time variability, we show how the breadth of this framework is such that it can serve as a coarse-grained foundation for understanding black hole accretion and jet formation across the mass scale.

description: We consider a quantum computation that only extracts one bit of information per $N$-qubit quantum state preparation. This is relevant for error mitigation schemes where the remainder of the system is measured to detect errors. We optimize the estimation of the expectation value of an operator by its linear decomposition into bitwise-measurable terms. We prove that optimal decompositions must be in terms of reflections with eigenvalues $\pm1$. We find the optimal reflection decomposition of a fast-forwardable operator, and show a numerical improvement over a simple Pauli decomposition by a factor $N^{0.7}$

description: With current space-based missions it is now possible to obtain age-sensitive asteroseismic information for tens of thousands of red giants. This provides a promising opportunity to study the Galactic structure and evolution. We use asteroseismic data of red giants, observed by Kepler, to test the current theoretical framework of modelling the Galaxy based on population synthesis modeling and the use of asteroseismic scaling relations for giants. We use the open source code Galaxia to model the Milky Way and find the distribution of the masses predicted by Galaxia to be systematically offset with respect to the seismically-inferred observed masses. The Galactic model overestimates the number of low mass stars, and these stars are predominantly old and of low metallicity. Using corrections to the $Δν$ scaling relation suggested by stellar models (available for download) significantly reduces the disagreement between predicted and observed masses. For a few cases where non-seismic mass estimates are available, the corrections to $Δν$ also improve the agreement between seismic and non-seismic mass estimates. The disagreement between predictions of the Galactic model and the observations is most pronounced for stars with ${\rm [Fe/H]}0$ or for $T_{\rm eff}>4700$ K. Altering the star formation rate in order to suppress stars older than 10 Gyr improves the agreement for mass but leads to inconsistent color distributions. We also tested the predictions of the TRILEGAL Galactic model. However, unlike {\sl Galaxia}, it had difficulties in reproducing the photometric properties of the Kepler Input Catalog because it overestimates the number of blue stars. We conclude that either the scaling relations and/or the Galactic models need to be revised to reconcile predictions of theory with asteroseismic observations.

description: Al occupancy and local structure (bond length and bond angles) for monoclinic \b{eta}-(AlxGa1-x)2O3 alloys, with Al compositions (x) up to 90%, have been determined from Rietveld refinement of x-ray diffraction data. Al atom preferentially occupies octahedron (Oh) atomic site in comparison to tetrahedron (Td) atomic site. However, sizable number of Td atomic sites i.e. 20% for Al composition of 5% remain occupied by Al atoms, which is found to increase sharply with Al composition. The Oh atomic sites are not fully occupied by Al atoms even for Al composition of 90%. The lattice parameters (band gap) of \b{eta}-(AlxGa1-x)2O3 alloy decrease (increases) linearly with Al composition, but a change in slope of variation of both lattice parameters and band gap is observed at around Al composition of 50%. The lattice is found to be distorted for Al compositions more than 50% as indicated by large change in the bond angles. The lattice distortion is determined to be the origin for the observed change in slope for the variation of both lattice parameters and band gap for monoclinic \b{eta}-(AlxGa1-x)2O3 alloy system. Our results provide an insight in to the local structure of \b{eta}-(AlxGa1-x)2O3 alloys, which are required to have better understanding of their physical properties.

description: Waveguide QED with cold atoms provides a potent platform for the study of non-equilibrium, many-body, and open-system quantum dynamics. Even with weak coupling and strong photon loss, the collective enhancement of light-atom interactions leads to strong correlations of photons arising in transmission, as shown in recent experiments. Here we apply an improved mean-field theory based on higher-order cumulant expansions to describe the experimentally relevant, but theoretically elusive, regime of weak coupling and strong driving of large ensembles. We determine the transmitted power, squeezing spectra and the degree of second-order coherence, and systematically check the convergence of the results by comparing expansions that truncate cumulants of few-particle correlations at increasing order. This reveals the important role of many-body and long-range correlations between atoms in steady state. Our approach allows to quantify the trade-off between anti-bunching and output power in previously inaccessible parameter regimes. Calculated squeezing spectra show good agreement with measured data, as we present here.

description: We compute the hadronic running of the electromagnetic and weak couplings in lattice QCD with $N_{\mathrm{f}}=2+1$ flavors of $\mathcal{O}(a)$ improved Wilson fermions. Using two different discretizations of the vector current, we compute the quark-connected and -disconnected contributions to the hadronic vacuum polarization (HVP) functions $\barΠ^{γγ}$ and $\barΠ^{γZ}$ for Euclidean squared momenta $Q^2\leq 7\,\mathrm{GeV}^2$. Gauge field ensembles at four values of the lattice spacing and several values of the pion mass, including its physical value, are used to extrapolate the results to the physical point. The ability to perform an exact flavor decomposition allows us to present the most precise determination to date of the $\mathrm{SU}(3)$-flavor-suppressed HVP function $\barΠ^{08}$ that enters the running of $\sin^2θ_{\mathrm{W}}$. Our results for $\barΠ^{γγ}$, $\barΠ^{γZ}$ and $\barΠ^{08}$ are presented in terms of rational functions for continuous values of $Q^2$ below $7 \,\mathrm{GeV}^2$. We observe a tension of up to $3.5$ standard deviation between our lattice results for $Δα^{(5)}_{\mathrm{had}}(-Q^2)$ and estimates based on the $R$-ratio for space-like momenta in the range $3$--$7\,\mathrm{GeV}^2$. The tension is, however, strongly diminished when translating our result to the $Z$ pole, by employing the Euclidean split technique and perturbative QCD, which yields $Δα^{(5)}_{\mathrm{had}}(M_Z^2)=0.027\,73(15)$ and agrees with results based on the $R$-ratio within the quoted uncertainties.

description: These are the slides from the LIBER 2020 Session Super-Charging Your RDM Impact. Session Description: Open Science has boosted the importance of Research Data Management (RDM). Research libraries have a key role in RDM, consisting of supporting the entire data life cycle through providing knowledge, skills, infrastructure and tools. To keep Research Data Findable, Accessible, Interoperable and Reusable (FAIR), we need to train our staff. This session focuses on several training programmes developed by LIBER institutions, teaching librarians and libraries the necessary skills to establish successful RDM. The first paper will present recommendations for research libraries to boost their research infrastructure impact, and to raise their research data services’ standards. The aim is to provide fresh ideas, in order to spark new discussions and deliberations among research infrastructure stakeholders on how research libraries can a) become catalytics actors in the research infrastructure ecosystem, b) strengthen their engagement with research infrastructures and c) raise awareness on research data infrastructures and management as well as open science. Secondly, Sven Vlaeminck and Olaf Siegert will introduce a successful data training program, developed for young economists and business researchers. After identifying a gap between increasingly data-intensive work and a lack of training provided in this area, this program was set up to train doctoral candidates in good practices in managing and documenting research data. In the talk, they will highlight the backgrounds of the workshop format as a spin-off from other library projects, describe the training elements and discuss the outcome of the evaluation of these events by participants. The plans of ZBW – Leibniz Information Centre for Economics for the future use of these workshop formats to foster open science practices and research integrity will also be discussed. Finally, Dr. Susanna Nykyri and Dr. Katja Fält will discuss responsible RDM collaboration in all university libraries in Finland within the context of national Open Science coordination and open data learning requirements and opportunities. They create joint solutions for research support services in RDM and open data, and share knowledge, material and best practices. RDM development work at Tampere University will also be discussed. The Tampere University Library trains researchers on RDM, OA publishing and research visibility, and coordinates the data service, which joins services of different service providers and supports RDM on a one-stop-shop basis.

description: Particle accelerators and storage rings have been transformative instruments of discovery, and, for many applications, innovations in particle-beam cooling have been a principal driver of that success1. Beam cooling reduces the spread in particle positions and momenta, while keeping the number of particles constant, and combats diffusive effects, thereby enabling particle accumulation and the production and preservation of intense beams. In the case of particle colliders, cooling increases the likelihood of observing rare physics events. One of the most important conceptual and technological advances in this area was stochastic cooling (SC), which was instrumental in the discovery of the W and Z bosons at CERN and the top quark at Fermilab2-6. SC reduces the random motion of the beam particles through granular sampling and correction of the beams phase-space structure, thus bearing resemblance to a Maxwells demon. The extension of SC from the microwave regime up to optical frequencies and bandwidths has long been pursued as it could increase the achievable cooling rates by three to four orders of magnitude and provide a powerful new tool for future accelerators. First proposed nearly thirty years ago, Optical Stochastic Cooling (OSC) replaces the conventional microwave elements of SC with optical-frequency analogs and is, in principle, compatible with any species of charged-particle beam7,8. Here we describe the first experimental demonstration of OSC in a proof-of-principle experiment9 at the Fermi National Accelerator Laboratorys Integrable Optics Test Accelerator10.

It is found that the sink strength strongly depends on misorientation angle. We also show that the ADFT is able to reproduce reasonably well the elastic properties and the point defect formation volume in $α$-iron.

description: Older adults population is growing at a faster pace than the evolution of health care system. Older adults have unique health care needs. It is imperative that all future physicians are prepared to care for the older adults. In 2009, the Canadian Geriatrics Society published its first set of core competencies for caring for older adults for graduating medical students. Based on the Geriatrics 5Ms and Can MEDS frameworks we revised the 2009 competencies using a modified Delphi method. Three Delphi surveys wee conducted from Oct 2019- June 2021. Consensus for all final competencies were >80 %.
 The new 33 core Aging Care 5Ms competencies were categorized under 7 major themes: aging, caring for older adults, mind, mobility and functions, medications, multi-complexity and matters the most. The aging care 5Ms competencies and a companion appendix were disseminated to Medical council of Canada and all Canadian Medical faculty deans in Jan 2022.

description: Exciton-polaritons have become an emerging platform for implementing non-Hermitian physics. The implementation commonly requires control of both the real and imaginary parts of the eigenmodes of the system. We present an experimental method to achieve this purpose using microcavities with sub-wavelength gratings as reflectors. The reflectivity and reflection phase of the grating can be changed by its geometric parameters and they determine the energy and linewidth of the polariton modes. We demonstrate that this method allows a wide range of possible polariton energy and linewidth, suitable for implementing non-Hermitian polariton systems with coupled modes.

description: Time evolving surfaces can be modeled as two-dimensional Functional time series, exploiting the tools of Functional data analysis. Leveraging this approach, a forecasting framework for such complex data is developed. The main focus revolves around Conformal Prediction, a versatile nonparametric paradigm used to quantify uncertainty in prediction problems. Building upon recent variations of Conformal Prediction for Functional time series, a probabilistic forecasting scheme for two-dimensional functional time series is presented, while providing an extension of Functional Autoregressive Processes of order one to this setting. Estimation techniques for the latter process are introduced and their performance are compared in terms of the resulting prediction regions. Finally, the proposed forecasting procedure and the uncertainty quantification technique are applied to a real dataset, collecting daily observations of Sea Level Anomalies of the Black Sea

description: Background
 Students and professors who had academic activities at the University Hospital of PUCPR participated in the activities. Patients/complex cases were previously selected and authorization was requested for visits to the bed and analysis of the medical records by the students involved in order to collect information, according to the specific needs of each undergraduate course. Afterwards, a previous discussion per course took place with the professors. The ultimate goal was the general discussion between all courses. For this general discussion, teams composed of ten students were organized, with at least one member from each course, who should answer the following guiding questions: 1) What information do colleagues from other professions have about the patient? 2) With regard to health care, what is the next step? 3) Describe the group's future expectations for the patient. After a 30-minute discussion, the teams' interlocutors presented items discussed with teachers acting as facilitators.
 •Summary of Results
 Activities took place in 2018, 2019 and 2022 involving approximately 400 students in teams of up to 10 students. The duration of each meeting was 1h30. In the first year, it was held in the form of team presentations in a large auditorium. In subsequent years, it was decided to distribute students in circular tables, composing small interprofessional teams for greater interaction.
 •Discussion and Conclusion
 From the discussions, points of attention that were not detected in isolation emerged, such as: unwanted drug interactions requiring better integration between physicians and pharmacists; the patient's body image interfering with food acceptance, asthenia and difficulties with physiotherapeutic activities; need to include the social service to direct the patient after discharge; dental intervention in the adjustment of prostheses, improving the patient's nutritional quality; integration of palliative care concepts. As a conclusion of students and teachers, the experience provided an expansion of the vision of patient-centered action and interprofessional action.

description: We consider optical spectroscopy of molecular junctions from the quantum transport perspective when radiation field is quantized and optical response of the system is simulated as photon flux. Using exact expressions for photon and electronic fluxes derived within the nonequilibrium Green function (NEGF) methodology and utilizing fourth order diagrammatic perturbation theory in molecular coupling to radiation field we perform simulations employing realistic parameters. Results of the simulations are compared to the bare perturbation theory (PT) usually employed in studies on nonlinear optical spectroscopy to classify optical processes. We show that the bare PT violates conservation laws, while flux conserving NEGF formulation mixes optical processes.

description: Second-generation Canadians are often referred to as the children of immigrants. Second-generation Canadians may find themselves in a position where the values of their parents or ethnic group are different to those of dominant Canadian culture; this dynamic has been documented within the second-generation South Asian Canadian population. The South Asian community traditionally views discussions of sexuality and intimate relations as taboo. This may have implications for how young second-generation South Asian Canadian womxn access sexual and reproductive health (SRH) information and care. This multi-method qualitative study explored the experiences of young second-generation South Asian Canadian women and other pregnancy capable people (womxn) accessing and receiving SRH information and care in Ontario through an anonymous online survey and in-depth interviews. We found that womxn's dual identity as Canadian and South Asian plays a role in their access to comprehensive SRH information and adequate SRH care. Privacy and confidentiality within the healthcare system impact use of information and services for this community. There is an evident need for improved information resources and education across all generations.

description: We realize higher-form symmetries in F-theory compactifications on non-compact elliptically fibered Calabi-Yau manifolds. Central to this endeavour is the topology of the boundary of the non-compact elliptic fibration, as well as the explicit construction of relative 2-cycles in terms of Lefschetz thimbles. We apply the analysis to a variety of elliptic fibrations, including geometries where the discriminant of the elliptic fibration intersects the boundary. We provide a concrete realization of the 1-form symmetry group by constructing the associated charged line operator from the elliptic fibration. As an application we compute the symmetry topological field theories in the case of elliptic three-folds, which correspond to mixed anomalies in 5d and 6d theories.

"User interaction mining: discovering the gap between the conceptual model of a geospatial search engine and its corresponding user mental model" describes a case study conducted at the National Geographic Institute of Spain. In this research, twenty-one participants, including novice and expert users, performed a search task with a new geospatial search engine. Their interactions were recorded as event logs and analysed with process mining techniques. The results helped to identify areas for improvement in product design that come from understanding the differences between the conceptual design of the interface and the mental model of the users. This case study illustrates the potential that interaction mining can add to the design and evaluation of new user interfaces.
Universal fluctuations and ergodicity of generalized diffusivity on critical percolation clusters

description: Despite a long history and a clear overall understanding of properties of random walks on an incipient infinite cluster in percolation, some important information on it seems to be missing in the literature. In the present work, we revisit the problem by performing massive numerical simulations for (sub)diffusion of particles on such clusters. Thus, we discuss the shape of the probability density function (PDF) of particles' displacements, and the way it converges to its long-time limiting scaling form. Moreover, we discuss the properties of the mean squared displacement (MSD) of a particle diffusing on the infinite cluster at criticality. This one is known not to be self-averaging. We show that the fluctuations of the MSD in different realizations of the cluster are universal, and discuss the properties of the distribution of these fluctuations. These strong fluctuations coexist with the ergodicity of subdiffusive behavior in the time domain. The dependence of the relative strength of fluctuations in time-averaged MSD on the total trajectory length (total simulation time) is characteristic for diffusion in a percolation system and can be used as an additional test to distinguish this process with disorder-induced memory from processes with otherwise similar behavior, like fractional Brownian motion with the same value of the Hurst exponent.

They include, in particular, $e^-e^+\to f\bar{f}$ and $e^-e^+\to W^-W^+$, where we validate the results of our implementation, improved with fixed-order corrections, with those obtained from the most precise calculations. We also show, for the first time, results for the Higgs-Strahlungs process, $e^-e^+\to ZH$, in YFS resummation including fixed-order improvements up to order $α^3L^3$.

description: We numerically study the finite-size droplet condensation-evaporation transition in two dimensions. We consider and compare two orthogonal approaches, namely at fixed temperature and at fixed density, making use of parallel multicanonical simulations. The equivalence between Ising model and lattice gas allows us to compare to analytical predictions. We recover the known background density (at fixed temperature) and transition temperature (at fixed density) in the thermodynamic limit and compare our finite-size deviations to the predicted leading-order finite-size corrections.

description: A variety of compounds, for example doped paraelectrics and polar metals, exhibit both ferroelectricity and correlated electronic phenomena such as low-density superconductivity and anomalous transport. Characterizing such properties is tied to understanding the quantum dynamics of inversion symmetry breaking in the presence of itinerant electrons. Here, we present a comprehensive analysis of the normal state properties of a metal near a quantum critical transition to a ferroelectric state, in both two and three dimensions. Starting from a minimal model of electrons coupled to a \emph{transverse} polar phonon via a Rashba-type spin-orbit interaction, we compute the dynamical response of both electrons and phonons. We find that the system can evince both Fermi and non-Fermi liquid phases, as well as enhanced pairing in both singlet and triplet channels. Furthermore, we systematically compute corrections to one-loop theory and find a tendency to quantum order-by-disorder, leading to a phase diagram that can include second order, first order, and finite-momentum phase transitions. Finally, we show that the entire phase diagram can be controlled via application of external strain, either compressive or volume-preserving. Our results provide a map of the dynamical and thermodynamical phase space of quantum ferroelectic metals, which can serve in characterizing existing materials and in seeking applications for quantum technologies.

description: The Near Earth Object Wide-field Infrared Survey Explorer (NEOWISE) Reactivation mission released data from its first full year of observations in 2015. This data set includes ~2.5 million exposures in each of W1 and W2, effectively doubling the amount of WISE imaging available at 3.4 and 4.6 microns relative to the AllWISE release. We have created the first ever full-sky set of coadds combining all publicly available W1 and W2 exposures from both the AllWISE and NEOWISE-Reactivation (NEOWISER) mission phases. We employ an adaptation of the unWISE image coaddition framework (Lang 2014), which preserves the native WISE angular resolution and is optimized for forced photometry. By incorporating two additional scans of the entire sky, we not only improve the W1/W2 depths, but also largely eliminate time-dependent artifacts such as off-axis scattered moonlight. We anticipate that our new coadds will have a broad range of applications, including target selection for upcoming spectroscopic cosmology surveys, identification of distant/massive galaxy clusters, and discovery of high-redshift quasars. In particular, our full-depth AllWISE+NEOWISER coadds will be an important input for the Dark Energy Spectroscopic Instrument (DESI) selection of luminous red galaxy and quasar targets. Our full-depth W1/W2 coadds are already in use within the DECam Legacy Survey (DECaLS) and Mayall z-band Legacy Survey (MzLS) reduction pipelines. Much more work still remains in order to fully leverage NEOWISER imaging for astrophysical applications beyond the solar system.

description: A 790-nm-driven high-harmonic generation source with a repetition rate of 6 kHz is combined with a toroidal-grating monochromator and a high-detection-efficiency photoelectron time-of-flight momentum microscope to enable time- and momentum-resolved photoemission spectroscopy over a spectral range of $23.6$-$45.5$ eV with sub-100-fs time resolution. Three-dimensional (3D) Fermi surface mapping is demonstrated on graphene-covered Ir(111) with energy and momentum resolutions of $\lesssim$$100$ meV and $\lesssim$$0.1$ $Å^{-1}$, respectively. The table-top experiment sets the stage for measuring the $k_z$-dependent ultrafast dynamics of 3D electronic structure, including band structure, Fermi surface, and carrier dynamics in 3D materials as well as 3D orbital dynamics in molecular layers.

description: Quantum information, in the form of entanglement with an ancilla, can be transmitted to a third system through interaction. Here, we investigate this process of entanglement transmission perturbatively in time. Using the entanglement monotone negativity, we determine how the proclivity of an interaction to either generate, transfer or lose entanglement depends on the choice of Hamiltonians and initial states. These three proclivities are captured by Hamiltonian- and state-dependent quantities that we call negativity susceptibility, negativity transmissibility and negativity vulnerability respectively. These notions could serve, for example, as cost functions in quantum technologies such as machine-learned quantum error correction.

description: We present two-dimensional gaseous kinematics of the inner 1.2 $\times$ 1.8 kpc$^2$ of the Seyfert 2 galaxy NGC3081, from optical spectra (5600--7000Å) obtained with the GMOS integral field spectrograph on the Gemini North telescope at a spatial resolution of $\approx$ 100pc. We have identified two-components in the line emitting gas. A narrower component (FWHM $\approx$ 60-100km s$^{-1}$), which appears to be gas in the galaxy disk, and which shows a distorted rotation pattern, is observed over the whole field of view. A broader component (FWHM $\approx$150-250 km s$^{-1}$) is present in the inner $\approx$ 2arcsec (200pc) and shows blueshifts and redshifts in the near and far sides of the galaxy, respectively, consistent with a bipolar outflow. Assuming this to be the case, we estimate that the mass outflow rate in ionized gas ($\dot{M}_{out}$) is between 1.9 $\times 10^{-3}$M$_{\odot}$ yr$^{-1}$ and 6.9 $\times 10^{-3}$M$_{\odot}$ yr$^{-1}$. The subtraction of a rotation model from the narrower component velocity field reveals a pattern of excess blueshifts of $\approx$ 50km s$^{-1}$ in the far side of the galaxy and similar excess redshifts in the near side, which are cospatial with a previously known nuclear bar. We interpret these residuals as due to gas following non-circular orbits in the barred potential. Under the assumption that these motions may lead to gas inflows, we estimate an upper limit for the mass inflow rate in ionized gas of $ϕ$ $\approx$ 1.3 $\times 10^{-2}$M$_{\odot}$ yr$^{-1}$.

2D Ising Field Theory in a Magnetic Field: The Yang-Lee Singularity

description: We study Ising Field Theory (the scaling limit of Ising model near the Curie critical point) in pure imaginary external magnetic field. We put particular emphasis on the detailed structure of the Yang-Lee edge singularity. While the leading singular behavior is controlled by the Yang-Lee fixed point ($=$ minimal CFT ${\cal M}_{2/5}$), the fine structure of the subleading singular terms is determined by the effective action which involves a tower of irrelevant operators. We use numerical data obtained through the "Truncated Free Fermion Space Approach" to estimate the couplings associated with two least irrelevant operators. One is the operator $T{\bar T}$, and we use the universal properties of the $T{\bar T}$ deformation to fix the contributions of higher orders in the corresponding coupling parameter $α$. Another irrelevant operator we deal with is the descendant $L_{-4}{\bar L}_{-4}ϕ$ of the relevant primary $ϕ$ in ${\cal M}_{2/5}$. The significance of this operator is that it is the lowest dimension operator which breaks integrability of the effective theory. We also establish analytic properties of the particle mass $M$ ($=$ inverse correlation length) as the function of complex magnetic field.

Series reversion for electrical impedance tomography with modeling errors

description: This work extends the results of [Garde and Hyvönen, Math. Comp. 91:1925-1953] on series reversion for Calderón's problem to the case of realistic electrode measurements, with both the internal admittivity of the investigated body and the contact admittivity at the electrode-object interfaces treated as unknowns. The forward operator, sending the internal and contact admittivities to the linear electrode current-to-potential map, is first proven to be analytic. A reversion of the corresponding Taylor series yields a family of numerical methods of different orders for solving the inverse problem of electrical impedance tomography, with the possibility to employ different parametrizations for the unknown internal and boundary admittivities. The functionality and convergence of the methods is established only if the employed finite-dimensional parametrization of the unknowns allows the Fréchet derivative of the forward map to be injective, but we also heuristically extend the methods to more general settings by resorting to regularization motivated by Bayesian inversion. The performance of this regularized approach is tested via three-dimensional numerical examples based on simulated data. The effect of modeling errors related to electrode shapes and contact admittances is a focal point of the numerical studies.

The Extreme Walking Behavior in a 331-TC Model

description: It is quite possible that the Technicolor problems are related to the poorly known self-energy expression, or the way chiral symmetry breaking (CSB) is realized in non-abelian gauge theories. Actually, the only known laboratory to test the CSB mechanism is QCD. The TC dynamics may be quite different from the QCD , this fact has led to the walking TC proposal making the new strong interaction almost conformal and changing appreciably its dynamical behavior. There are different ways to obtain of extreme walking (or quasi-conformal) technicolor theories, in this paper we propose an scheme to obtain this behavior based on an extension of the electroweak sector of the standard model, in the context of so called 331-TC model.

A Unified Description for Polarization-Transfer Mechanisms in Magnetic Resonance in Static Solids: Cross Polarization and DNP

description: Polarization transfers are crucial building blocks in magnetic resonance experiments, i.e., they can be used to polarize insensitive nuclei and correlate nuclear spins in multidimensional NMR spectroscopy. The polarization can be transferred either across different nuclear spin species or from electron spins to the relatively low-polarized nuclear spins. The former route occurring in solid-state NMR (ssNMR) can be performed via cross polarization (CP), while the latter route is known as dynamic nuclear polarization (DNP). Despite having different operating conditions, we opinionate that both mechanisms are theoretically similar processes in ideal conditions, i.e., the electron is merely another spin-1/2 particle with a much higher gyromagnetic ratio. Here, we show that the CP and DNP processes can be described using a unified theory based on average Hamiltonian theory (AHT) combined with fictitious operators. The intuitive and unified approach has allowed new insights on the cross effect (CE) DNP mechanism, leading to better design of DNP polarizing agents and extending the applications beyond just hyperpolarization. We explore the possibility of exploiting theoretically predicted DNP transients for electron-nucleus distance measurements--like routine dipolar-recoupling experiments in solid-state NMR.
