description: The nitrogen-vacancy (NV) center has enabled widespread study of nanoscale nuclear magnetic resonance (NMR) spectroscopy at low magnetic fields. NMR spectroscopy at high magnetic fields significantly improves the technique's spectral resolution, enabling clear identification of closely related chemical species. However, NV-detected NMR is typically performed using AC sensing through electron spin echo envelope modulation (ESEEM), a hyperfine spectroscopic technique that is not feasible at high magnetic fields. Within this paper, we have explored an NV-detected NMR technique for applications of high field NMR. We have demonstrated optically detected magnetic resonance (ODMR) with the NV Larmor frequency of 230 GHz at 8.3 Tesla, corresponding to a proton NMR frequency of 350 MHz. We also demonstrated the first measurement of electron-electron double resonance detected NMR (EDNMR) using the NV center and successfully detected $^{13}C$ nuclear bath spins. The described technique is limited by the longitudinal relaxation time ($T_1$), not the transverse relaxation time ($T_2$). Future applications of the method to perform nanoscale NMR of external spins at 8.3 T and even higher magnetic fields are also discussed.

description: We study the Schwinger process in a uniform non-Abelian electric field using a dynamical approach in which we evolve an initial quantum state for gluonic excitations. We evaluate the spectral energy density and number density in the excitations as functions of time. The total energy density has an ultraviolet divergence which we argue gets tamed due to asymptotic freedom, leading to $g^4E^4t^4$ growth, where $g$ is the coupling and $E$ the electric field strength. We also find an infrared divergence in the number density of excitations whose resolution requires an effect such as confinement.

description: We study the $S_3$-symmetric two Higgs doublet model by adding two generations of vector like leptons (VLL) which are odd under a discrete $Z_2$ symmetry. The lightest neutral component of the VLL acts as a dark matter (DM) whereas the full VLL set belongs to a dark sector with no mixings allowed with the standard model fermions. We analyse the model in light of dark matter and collider searches. We show that the DM is compatible with the current relic density data as well as satisfying all direct and indirect dark matter search constraints. We choose some representative points in the model parameter space allowed by all aforementioned dark matter constraints and present a detailed collider analysis of multi-lepton signal viz. the mono-lepton, di-lepton, tri-lepton and four-lepton along with missing transverse energy in the final state using both the cut-based analysis and multivariate analysis respectively at the high luminosity 14 TeV LHC run.

SunPy Proposal for Enhancement 9: Release Pattern for SunPy Core (SEP 0009)

description: This SEP defines a release pattern for the SunPy core package and defines a versioning system. Since SunPy is being used more widely both by users as well as developers as a dependency, it is important to have clear and predictable releases.  This is especially important to support other Python packages which have SunPy as a dependency (e.g. affiliated packages). A predictable release and support cycle for the SunPy core package will aid these packages in planning their own development cycle.

The focus of this SEP is not to prescribe how quickly the core package improves through the introduction of new features or API changes but how and when release occur and how they are described.

Test/non-test variations in the composing behaviours of academic ESL writers
Creators: name: Hall, Ernest W.
Publisher: name: University of British Columbia
Year: 2010

description: Fluctuations in the quality of text produced by an individual writer from day to day have long been recognized, but variations in composing processes which may account for this have largely been overlooked as an area of study in the composition research both in English as a first language and in English as a second language. While process tracing research has revealed great variation among individual writers and among types of writers, and in the quality of writing an individual may produce from time to time, fluctuation in writing behaviours has been ignored. By closely observing, through video techniques, six ESL writers who had demonstrated considerable inconsistency in the quality of their writing, this study examined differences in their behaviours as they wrote in two situations: one a practice essay composition test, and the other an actual English composition proficiency examination. The subjects observed were selected because they had failed the examination at least twice before contrary to the predictions of their instructors. The researcher speculated that this inconsistency in their ability to perform was related to the heightened stress of the examination situation. Between the situations, variations were observed in the complexity of the texts generated, in the allocation of time to various composing activities, in the writers' pausing behaviours, and in the type of alterations they made while inscribing. In addition, each of the six writers displayed a unique profile in approaching the writing tasks. The findings of the study suggest that assessment and instructional practices need to address writing problems as distinct from language proficiency problems and that assessment and instruction practices need to attend to behaviours during the writing act while accounting for student writers who are unusually apprehensive about writing or who suffer from high levels of anxiety in test situations. The findings also reiterate the long-standing suspicion about the validity of assessing writing skill based on a single sample of a student's writing.
Hybridized hyperbolic surface phonon polaritons at α-MoO3 and polar dielectric interfaces

description: Surface phonon polaritons (SPhPs) in polar dielectrics offer new opportunities for infrared nanophotonics due to sub-diffraction confinement with low optical losses. Though the polaritonic field confinement can be significantly improved by modifying the dielectric environment, it is challenging to break the fundamental limits in photon confinement and propagation behavior of SPhP modes. In particular, as SPhPs inherently propagate isotropically in these bulk polar dielectrics, how to collectively realize ultra-large field confinement, in-plane hyperbolicity and unidirectional propagation remains elusive. Here, we report an approach to solve the aforementioned issues of bulk polar dielectric's SPhPs at one go by constructing a heterostructural interface between biaxial van der Waals material (e.g., MoO3) and bulk polar dielectric (e.g., SiC, AlN, and GaN). Due to anisotropy-oriented mode couplings at the interface, the hybridized SPhPs with a large confinement factor (>100) show in-plane hyperbolicity that has been switched to the orthogonal direction as compared to that in natural MoO3. More interestingly, this proof of concept allows steerable, angle-dependent and unidirectional polariton excitation by suspending MoO3 on patterned SiC air cavities. Our finding exemplifies a generalizable framework to manipulate the flow of nano-light and engineer unusual polaritonic responses in many other hybrid systems consisting of van der Waals materials and bulk polar dielectrics.

A resummed perturbative estimate for the quarkonium spectral function in hot QCD

description: By making use of the finite-temperature real-time static potential that was introduced and computed to leading non-trivial order in Hard Thermal Loop resummed perturbation theory in recent work, and solving numerically a Schrödinger-type equation, we estimate the quarkonium (in practice, bottomonium) contribution to the spectral function of the electromagnetic current in hot QCD. The spectral function shows a single resonance peak which becomes wider and then disappears as the temperature is increased beyond 450 MeV or so. This behaviour can be compared with recently attempted lattice reconstructions of the same quantity, based on the ``maximum entropy method'', which generically show several peaks. We also specify the dependence of our results on the spatial momentum of the electromagnetic current, as well as on the baryon chemical potential characterising the hot QCD plasma.

Doping-driven Mott transition in La_{1-x}Sr_xTiO_3 via simultaneous electron and hole doping of t2g subbands

description: The insulator to metal transition in LaTiO_3 induced by La substitution via Sr is studied within multi-band exact diagonalization dynamical mean field theory at finite temperatures. It is shown that weak hole doping triggers a large interorbital charge transfer, with simultaneous electron and hole doping of t2g subbands. The transition is first-order and exhibits phase separation between insulator and metal. In the metallic phase, subband compressibilities become very large and have opposite signs. Electron doping gives rise to an interorbital charge flow in the same direction as hole doping. These results can be understood in terms of a strong orbital depolarization.

description: For a given Jacobi-Jordan algebra $A$ and a vector space $V$ over a field $k$, a non-abelian cohomological type object ${\mathcal H}^{2}_{A} \, (V, \, A)$ is constructed: it classifies all Jacobi-Jordan algebras containing $A$ as a subalgebra of codimension equal to ${\rm dim}_k (V)$. Any such algebra is isomorphic to a so-called \emph{unified product} $A \, \natural \, V$. Furthermore, we introduce the bicrossed (semi-direct, crossed, or skew crossed) product $A \bowtie V$ associated to two Jacobi-Jordan algebras as a special case of the unified product. Several examples and applications are provided: the Galois group of the extension $A \subseteq A \bowtie V$ is described as a subgroup of the semidirect product of groups ${\rm GL}_k (V) \rtimes {\rm Hom}_k (V, \, A)$ and an Artin type theorem for Jacobi-Jordan algebra is proven. The key tools for classifying supersolvable and flag Jacobi-Jordan algebras are introduced.

description: An exotic approach to hadrons is discussed. It is based on the recently developed open-closed string duality explicitly conjectured as the AdS/CFT correspondence. Mesons as well as pentaquarks are studied in this approach. Spins are introduced as distribution functions over the string, and a second quantization method of string theory is examined and used to estimate the mass and decay width of various hadrons. This approach provides a way to understand the structure of flavor by a configuration of probe branes.

At the threshold of prompt collapse, we find type II critical phenomena (apparent horizon mass and maximum curvature scale as powers of distance from the threshold) for $κ\gtrsim 0.43$, and type I critical phenomena (lifetime scales as logarithm of distance from the threshold) for $κ\lesssim 0.42$. The type I critical solution is static, while the type II critical solution is not self-similar (as in higher dimensions) but contracting quasi-statically.

description: Motivated by recent Hall-effect experiment in YbRh$_2$Si$_2$, we study ground state properties of a Kondo lattice model in a two-dimensional square lattice using variational Monte Carlo method. We show that there are two types of phase transition, antiferromagnetic transition and topological one (Fermi surface reconstruction). In a wide region of parameters, these two transitions occur simultaneously without the breakdown of Kondo screening, accompanied by a discontinuous change of the Hall coefficient. This result is consistent with the experiment and gives a novel theoretical picture for the quantum critical point in heavy fermion systems.

description: We define and study the probability current and the Hamiltonian operator for a fully general set of Dirac matrices in a flat spacetime with affine coordinates, by using the Bargmann-Pauli hermitizing matrix. We find that with some weak conditions on the affine coordinates, the current, as well as the spectrum of the Dirac Hamiltonian, thus all of quantum mechanics, are independent of that set. These results allow us to show that the tensor Dirac theory, which transforms the wave function as a spacetime vector and the set of Dirac matrices as a third-order affine tensor, is physically equivalent to the genuine Dirac theory, based on the spinor transformation. The tensor Dirac equation extends immediately to general coordinate systems, thus to non-inertial (e.g. rotating) coordinate systems.

Analytical and numerical methods, based on the mean-field description of the condensate, are developed to study both stationary as well as time-dependent propagation processes. We apply these methods to the propagation of a condensate through an atomic quantum dot in a waveguide, discuss the nonlinear transmission spectrum and show that resonant transport is generally suppressed due to an interaction-induced bistability phenomenon. Finally, we establish a link between the nonlinear features of the transmission spectrum and the self-consistent quasi-bound states of the quantum dot.

description: We show that the classical scale symmetry of a particle moving in cosmic string background is broken upon inequivalent quantization of the classical system, leading to anomaly. The consequence of this anomaly is the formation of single bound state in the coupling interval γ\in(-1,1). The inequivalent quantization is characterized by a 1-parameter family of self-adjoint extension parameter ω. It has been conjectured that the formation of loosely bound state in cosmic string background may lead to the so called anomalous scattering cross section for the particles, which is usually seen in molecular physics.

description: The risk for severe illness and mortality from COVID-19 significantly increases with age. As a result, age-stratified modeling for COVID-19 dynamics is the key to study how to reduce hospitalizations and mortality from COVID-19. By taking advantage of network theory, we develop an age-stratified epidemic model for COVID-19 in complex contact networks. Specifically, we present an extension of standard SEIR (susceptible-exposed-infectious-removed) compartmental model, called age-stratified SEAHIR (susceptible-exposedasymptomatic-hospitalized-infectious-removed) model, to capture the spread of COVID-19 over multitype random networks with general degree distributions. We derive several key epidemiological metrics and then propose an age-stratified vaccination strategy to decrease the mortality and hospitalizations. Through extensive study, we discover that the outcome of vaccination prioritization depends on the reproduction number R0. Specifically, the elderly should be prioritized only when R0 is relatively high. If ongoing intervention policies, such as universal masking, could suppress R0 at a relatively low level, prioritizing the high-transmission age group (i.e., adults aged 20-39) is most effective to reduce both mortality and hospitalizations. These conclusions provide useful recommendations for age-based vaccination prioritization for COVID-19.

description: We consider one of the simplest time-dependent backgrounds in M-theory, describing the shrinking away of the M-theory dimension with the other spatial dimensions static. As the M-theory dimension becomes small, the situation becomes well-described by string theory in a singular cosmological background where the string coupling tends to zero but the $α'$-corrections become large, near the cosmic singularity. We compute these $α'$-corrections, both for the background and for linearized perturbations, in heterotic string theory, and show they may be reproduced by a map from eleven-dimensional M-theory.

description: Let K be a field of characteristic p>0, and let q be a power of p. We determine all polynomials f in K[t]\K[t^p] of degree q(q-1)/2 such that the Galois group of f(t)-u over K(u) has a transitive normal subgroup isomorphic to PSL_2(q), subject to a certain ramification hypothesis. As a consequence, we describe all polynomials f in K[t], of degree not a power of p, such that f is functionally indecomposable over K but f decomposes over an extension of K. Moreover, except for one ramification setup (which is treated in the companion paper arxiv:0707.1837), we describe all indecomposable polynomials f in K[t] of non-p-power degree which are exceptional, in the sense that x-y is the only absolutely irreducible factor of f(x)-f(y) which lies in K[x,y]. It is known that, when K is finite, a polynomial f is exceptional if and only if it induces a bijection on infinitely many finite extensions of K.

description: The multi-frequency Sedentary Survey is a flux limited, statistically well-defined sample of highly X-ray dominated BL Lacertae objects (HBLs) which includes 150 sources. In this paper, the third of the series, we report the results of a dedicated optical spectroscopy campaign that, together with results from other independent optical follow up programs, led to the spectroscopic identification of all sources in the sample. We carried out a systematic spectroscopic campaign for the observation of all unidentified objects of the sample using the ESO 3.6m, the KPNO 4m, and the TNG optical telescopes. We present new identifications and optical spectra for 76 sources, 50 of which are new BL Lac objects, 18 are sources previously referred as BL Lacs but for which no redshift information was available, and 8 are broad emission lines AGNs. We find that the multi-frequency selection technique used to build the survey is highly efficient (about 90%) in selecting BL Lacs objects. We present positional and spectroscopic information for all confirmed BL Lac objects. Our data allowed us to determined 36 redshifts out of the 50 new BL Lacs and 5 new redshifts for the previously known objects. The redshift distribution of the complete sample is presented and compared with that of other BL Lacs samples. For 26 sources without recognizable absorption features, we calculated lower limits to the redshift using a method based on simulated optical spectra with different ratios between jet and galaxy emission. For a subsample of 38 object with high-quality spectra, we find a correlation between the optical spectral slope, the 1.4 GHz radio luminosity, and the Ca H&K break value, indicating that for powerful/beamed sources the optical light is dominated by the non-thermal emission from the jet.

The effects of visual format and mode of presentation on nonnative speaker comprehension of verbal information
Creators: name: Fitzpatrick, Dale Mary
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to gather data on nonnative speakers' comprehension of spoken language presented via the audio mode (sound only) or the video mode (sound + picture). More specifically, the research examined the effects of three visual formats (or picture content)--contained in the video channel—on comprehension of verbal information carried in the audio channel of broadcast news stories. The three visual formats under investigation were: (1) high redundancy (HR): voice-over-film with similar verbal and visual content; (2) low redundancy (LR): voice-over-film with dissimilar verbal and visual content, and (3) talking head: newscaster only presentation, without film. A smaller follow-up study examined the effect of visuals with a group of subjects of higher second-language proficiency. The procedure utilized a between-and-within-subjects design and nine news stories videotaped from CBC television, categorized according to visual format. Stimulus news stories were presented to subjects via either the video or audio mode. After each story, actual comprehension o£ verbal information was measured using a test of cued-recall and perceived language comprehension was measured using a self-reporting question. In the video mode, subjects were also asked to rate the difficulty of each story. The results of an analysis of variance indicated that, under the conditions of the present study, subjects scored significantly higher on a test o£ cued recall when news stories were presented via the video mode. Significant differences were also found between language comprehension scores for each of the visual formats. Highest scores were obtained for the HR stories, and lowest scores for the TH stories. From the results of the follow-up study, it appears the comprehension-facilitating effect of visuals is not as strong for subjects of higher proficiency. Results are discussed in light of literature on media and learning, the relationship between aural and visual channels, visual format effects and television news, listening comprehension, and visual information processing. Implications and suggestions for further study are presented.

feedback of research results

description: This policy recommendation covers general feedback of the results of research studies conducted with data provided through 1+MG to data subjects. The 1+MG policy covers: ● what information should and should not (necessarily) be shared with data subjects (and potentially other people interested in 1+MG); ● how this information should be shared (e.g. through which medium and in which language(s)). The 1+MG policy only applies to analyses conducted in the context of 1+MG data sharing. Data uses addressed in the primary data collection context should be covered by local policies. In an analysis of current guidelines and best practices, we identified three important principles to provide feedback of general research results to data subjects: transparency, accountability, and the fair distribution of benefits. Providing feedback towards data subjects about general research results contributes to transparency, and as a result, accountability, about conducted studies with health data. Factors that contribute to the need for transparency and accountability, both towards data subjects and the general public, are the use of public funding to set up the infrastructure, collect the data, and conduct the studies, and the fact that in observational research, it is often difficult to provide a detailed account of the exact studies that will be conducted with the data at the moment the data subject is informed about participation. In the long run, providing feedback may add to the (prolonged) trust of data subjects and the broader society in 1+MG and health research in general. The third principle, fair distribution of benefits from the data infrastructure, should not only be seen as the fair distribution of the resulting clinical progress, but also as the fair distribution of knowledge gained from the use of data. Sharing general research results adds to this knowledge sharing. Based on these three principles, a recommendation to provide feedback of general research results to data subjects is set up. Other considerations are taken into account when determining how to provide this feedback. In the 1+MG federated infrastructure, the responsibility to engage with data subjects lies with the signatories. It is therefore presumed that feedback is organised by the national nodes. Practical issues, such as restricted time and expertise available to develop information that is clear to data subjects, are taken into account. Below we summarise the recommendations and provide a short list of best practices.

Particle creation in nonstationary large N quantum mechanics

description: We consider an analog of particle production in a quartic $O(N)$ quantum oscillator with time-dependent frequency, which is a toy model of particle production in the dynamical Casimir effect and de Sitter space. We calculate exact quantum averages, Keldysh propagator, and particle number using two different methods. First, we employ a kind of rotating wave approximation to estimate these quantities for small deviations from stationarity. Second, we extend these results to arbitrarily large deviations using the Schwinger-Keldysh diagrammatic technique. We show that in strongly nonstationary situations, including resonant oscillations, loop corrections to the tree-level expressions effectively result in an additional degree of freedom, $N \to N + \frac{3}{2}$, which modifies the average number and energy of created particles.

description: Venus’ appearance is deceptive. The history of scientific research about Venus is full of mistaken assumptions that are sooner or later refuted by new observations. Ancient civilizations wrongly interpreted the morning and evening stars as 2 stars. Giovanni Cassini claimed to have observed moons. More recently, scientists assumed that Venus’ reflective clouds prevented solar energy from reaching its surface, leaving it cold. Its surface is actually hotter than Mercury’s surface. Even today, sophisticated numerical models that work to predict the behavior of atmospheres on other planets are unable to reproduce even basic properties of the atmosphere of Venus.

A new family of exceptional polynomials in characteristic two

description: We produce a new family of polynomials f(x) over fields K of characteristic 2 which are exceptional, in the sense that f(x)-f(y) has no absolutely irreducible factors in K[x,y] besides the scalar multiples of x-y; when K is finite, this condition is equivalent to saying there are infinitely many finite extensions L/K for which the map c --> f(c) is bijective on L. Our polynomials have degree (2^e-1)*2^(e-1), where e is odd. Combined with our previous paper arxiv:0707.1835, this completes the classification of indecomposable exceptional polynomials of degree not a power of the characteristic. The strategy of our proof is to identify the curves that can arise as the Galois closure of the branched cover P^1 --> P^1 induced by an exceptional polynomial f. In this case, the curves turn out to be x^(q+1)+y^(q+1)=a+T(xy), where T(z)=z^(q/2)+z^(q/4)+...+z. Our proofs rely on new properties of ramification in Galois covers of curves, as well as the computation of the automorphism groups of all curves in a certain 2-parameter family.
