description: Variable selection is a difficult problem that is particularly challenging in the analysis of high-dimensional genomic data. Here, we introduce the CAR score, a novel and highly effective criterion for variable ranking in linear regression based on Mahalanobis-decorrelation of the explanatory variables. The CAR score provides a canonical ordering that encourages grouping of correlated predictors and down-weights antagonistic variables. It decomposes the proportion of variance explained and it is an intermediate between marginal correlation and the standardized regression coefficient. As a population quantity, any preferred inference scheme can be applied for its estimation. Using simulations we demonstrate that variable selection by CAR scores is very effective and yields prediction errors and true and false positive rates that compare favorably with modern regression techniques such as elastic net and boosting. We illustrate our approach by analyzing data concerned with diabetes progression and with the effect of aging on gene expression in the human brain. The R package "care" implementing CAR score regression is available from CRAN.

description: Absorption features in stellar atmospheres are often used to calibrate photocentric velocities for kinematic analysis of further spectral lines. The Li feature at $\sim$ 6708 Å is commonly used, especially in the case of young stellar objects for which it is one of the strongest absorption lines. However, this is a complex line comprising two isotope fine-structure doublets. We empirically measure the wavelength of this Li feature in a sample of young stars from the PENELLOPE/VLT programme (using X-Shooter, UVES and ESPRESSO data) as well as HARPS data. For 51 targets, we fit 314 individual spectra using the STAR-MELT package, resulting in 241 accurately fitted Li features, given the automated goodness-of-fit threshold. We find the mean air wavelength to be 6707.856 Å, with a standard error of 0.002 Å (0.09 km/s) and a weighted standard deviation of 0.026 Å (1.16 km/s). The observed spread in measured positions spans 0.145 Å, or 6.5 km/s, which is up to a factor of six higher than typically reported velocity errors for high-resolution studies. We also find a correlation between the effective temperature of the star and the wavelength of the central absorption. We discuss how exclusively using this Li feature as a reference for photocentric velocity in young stars could potentially be introducing a systematic positive offset in wavelength to measurements of further spectral lines. If outflow tracing forbidden lines, such as [O i] 6300 Å, are actually more blueshifted than previously thought, this then favours a disk wind as the origin for such emission in young stars.

description: In the framework of bilinear control of the Schrödinger equation with bounded control operators, it has been proved that the reachable set has a dense complemement in ${\cal S}\cap {\cal H}^{2}$. Hence, in this setting, exact quantum control in infinite dimensions is not possible. On the other hand it is known that there is a simple choice of operators which, when applied to an arbitrary state, generate dense orbits in Hilbert space. Compatibility of these two results is established in this paper and, in particular, it is proved that the closure of the reachable set of bilinear control by bounded operators is dense in ${\cal S}\cap {\cal H}^{2}$. The requirements for controllability in infinite dimensions are also related to the properties of the infinite dimensional unitary group.

They resuscitated patients and enrolled them in the registry with informed consent. All of the data were reviewed by the well-trained EM staff who majored in critical care and decided on the final inclusion. After excluding septic shock-mimic cases, EM physicians collected numerous variables, including demographic data, laboratory data, radiologic results, treatment-related parameters, and clinical outcomes. For the secondary analysis, investigators who were involved this study extracted additional data, such as culture results, and time-to-positivity.

description: The rigorous quantum mechanical description of the collective interaction of many molecules with the radiation field is usually considered numerically intractable, and approximation schemes must be employed. Standard spectroscopy usually contains some levels of perturbation theory, but under strong coupling conditions, other approximations are used. A common approximation is the 1-exciton model in which processes involving weak excitations are described using a basis comprising of the ground state and singly excited states of the molecule cavity-mode system. In another frequently used approximation in numerical investigations, the electromagnetic field is described classically, and the quantum molecular subsystem is treated in the mean-field Hartree approximation with its wavefunction assumed to be a product of single molecules' wavefunctions. The former disregards states that take long time to populate, and is therefore essentially a short time approximation. The latter is not limited in this way, but by its nature, disregards some intermolecular and molecule-field correlations. In this work, we directly compare results obtained from these approximations when applied to several prototype problems involving the optical response of molecule-in-optical cavities systems. In particular, we show that our recent model investigation (J. Chem. Phys. 157, 114108 (2022)) of the interplay between the electronic strong coupling and molecular nuclear dynamics using the truncated 1-exciton approximation agrees very well with the semiclassical mean-field calculation.

description: This paper outlines arbitral tribunals’ power to order provisional measures undertheauspicesofI.C.S.I.D.Arbitration;that is,investor-state arbitration. The scope of a tribunal’s power is cumbersome to discern, especially when there are possible interferences with state sovereignty. More recently, tribunals have ordered provisional measures to suspend a domestic criminal investigation or proceeding. Is this an infringement on a states sovereign prerogatives or a response to, for example, dilatory tactics by a rogue state? The crux of the issue is this: a state will always be in a position to utilize its prosecutorial powers in order to frustrate the arbitration by putting immense pressure on the investor, its employees, or its witnesses, in other words: “playing games” in local courts. In order to guarantee procedural integrity of the arbitration and, as a corollary, the legitimacy of investor-state arbitration in its entirety, the provisional measure is a practical tool that can be used effectively. On a similar vein, “sovereignty” should not force tribunals to tie their hands when serious interference with the arbitral procedure is making the procedure unfair at best,or a nullity at worst. However, legal text both empowers and constrains the tribunal. The I.C.S.I.D. Convention only allows a tribunal to “recommend” provisional measures. As seen in light of investor-state case law, in an informal (perhaps de facto) stare decisis context, a number of tribunals seem to have justiﬁed the ordering of provisional measures. In the shadow of this construction lurks the de-legitimizing of the entire investor-state arbitration system. At the same time, rogue sovereigns playing games in local courts have the same de-legitimizing effect.

description: The addition of a Ricci coupling to Einstein-scalar-Gauss-Bonnet theories makes general relativity a cosmological attractor. Previous work considered a quadratic coupling function with two independent coupling constants in such theories and showed that static, spherically symmetric, spontaneously scalarized black holes are radially stable beyond a critical value of the Ricci coupling constant. Here we demonstrate that these black holes are affected by a quadrupole instability which leads to two new branches of static, axially symmetric scalarized black holes. We discuss the properties of these solutions and provide embedding diagrams.

description: We study transport properties of a single-molecule magnet (SMM) weakly coupled to one nonmagnetic and one ferromagnetic lead. Using the diagrammatic technique in real time, we calculate transport in the sequential and cotunneling regimes for both ferromagnetic and antiferromagnetic exchange coupling between the molecule's LUMO level and the core spin. We show that the current flowing through the system is asymmetric with respect to the bias reversal, being strongly suppressed for particular bias polarizations. Thus, the considered system presents a prototype of a SMM spin diode. In addition, we also show that the functionality of such a device can be tuned by changing the position of the molecule's LUMO level and strongly depends on the type of exchange interaction.

description: A regular class of static, cylindrically symmetric pure magnetic field metrics is rederived in a different metric ansatz in all dimensions. Radial, time dependent perturbations show that for dimensions d>3 such spacetimes are stable at both near r\approx0 and large radius r\rightarrow\infty. In a different gauge these stability analysis and similar results were known beforehand. For d=3, however, simultaneous stability requirement at both, near and far radial distances can not be reconciled for time - dependent perturbations. Restricted, numerical geodesics for neutral particles reveal a confinement around the center in the polar plane. Charged, time-like geodesics for d=4 on the other hand are shown numerically to run toward infinity.

description: The formation of molecular gas in interstellar clouds is a slow process, but is enhanced by gas compression. Magnetohydrodynamic (MHD) waves create compressed quasiperiodic linear structures, referred to as striations. Striations are observed at column densities where the atomic to molecular gas transition takes place. We explore the role of MHD waves in the CO chemistry in regions with striations within molecular clouds. We target a region with striations in the Polaris Flare cloud. We conduct a CO J=2-1 survey in order to probe the molecular gas properties. We use archival starlight polarization data and dust emission maps in order to probe the magnetic field properties and compare against the CO properties. We assess the interaction of compressible MHD wave modes with CO chemistry by comparing their characteristic timescales. The estimated magnetic field is 38 - 76 $μ$G. In the CO integrated intensity map, we observe a dominant quasi-periodic intensity structure, which tends to be parallel to the magnetic field orientation and has a wavelength of one parsec approximately. The periodicity axis is $\sim$ 17 degrees off from the mean magnetic field orientation and is also observed in the dust intensity map. The contrast in the CO integrated intensity map is $\sim 2.4$ times larger than the contrast of the column density map, indicating that CO formation is enhanced locally. We suggest that a dominant slow magnetosonic mode with estimated period $2.1 - 3.4$ Myr, and propagation speed $0.30 - 0.45$ km~s$^{-1}$, is likely to have enhanced the formation of CO, hence created the observed periodic pattern. We also suggest that, within uncertainties, a fast magnetosonic mode with period 0.48 Myr and velocity $2.0$ km~s$^{-1}$ could have played some role in increasing the CO abundance. Quasiperiodic CO structures observed in striation regions may be the imprint of MHD wave modes.

Разнообразие вызовов, которые сейчас стоят перед ЕС, их чрезвычайная масштабность и разносторонность дают основание говорить о системном кризисе евроинтеграционного процесса, который не является случайностью, а выступает результатом длительного накопления предпосылок еще с периода триумфальной евроинтеграции.
High-precision solution of the Dirac Equation for the hydrogen molecular ion using a basis-set expansion

description: The Dirac equation for H$_2^+$ is solved numerically by expansion in a basis set of two-center exponential functions, using different kinetic balance schemes. Very high precision (27-32 digits) is achieved, either with the dual kinetic balance, which provides the fastest convergence, or without imposing any kinetic balance condition. Application to heavy molecular ions is also illustrated. Calculation of relativistic sum rules shows that this method gives an accurate representation of the complete Dirac spectrum, making it a promising tool for calculations of QED corrections in molecular systems.
Partisanship, ideology, and civic autonomy : towards a comprehensive framework for measuring autonomy in Canadian cities
Creators: name: Kowalchuk, Katelynn Rae
Publisher: name: University of British Columbia
Year: 2022

description: Notwithstanding the expansion of the role, capacity and democratic legitimacy of municipal governments in modern public life in Canada, they remain vulnerable to the whims of their respective provincial governments. Smith and Spicer’s (2018) work, “The Local Autonomy of Canada’s Largest Cities”, is the first attempt within the Canadian urban politics field to quantitatively measure local autonomy in Canadian cities, drawing on previous qualitative research within Canada and international quantitative indices. Most of their measures of local autonomy are naturally suited to quantitative research (such as per capita expenditures); however, other measures are more challenging to place within a quantitative framework, prompting the opportunity for critique and refinement. My thesis argues that two of Smith and Spicer’s indicators of political autonomy are not fully supported by the literature, lack a strong theoretical narrative for their explanatory power, and are limited by the constraints of their strictly quantitative methodology. Additionally, I contend that their universality is overestimated, and that political autonomy would be captured more powerfully through an understanding of the historical context and the motivations of powerful actors in cities and provincial capitals. These two measures of political autonomy, and Smith and Spicer’s index more broadly, would benefit from additional nuance stemming from historical qualitative research which can illuminate the details, contingencies, and unique dynamics that can be lost within the requirements of quantitative research. My thesis aims to demonstrate the importance of capturing this nuance through an examination of the history of Vancouver politics vis-à-vis the BC provincial government throughout the 1930s. This historiography supports my assertion that political actors are not bound by the institutional constraints assumed by Smith and Spicer’s measures of political interconnectivity. Rather than Smith and Spicer’s assumption that politically migratory politicians will always support policy which favours municipalities, one can adopt an alternative institutionalist lens which instead assumes the careerist aspirations of Canadian politicians and how they behave when vying for political power. The presence of a political threat further contributes to this behaviour, suggesting that the index may benefit from accounting for ideological and partisan conflicts.

description: The investigation of the feedback cycle in galaxy clusters has historically been performed for systems where feedback is ongoing ("mature-feedback" clusters), that is where the central radio galaxy has inflated radio lobes, pushing aside the intracluster medium (ICM). In this pilot study we present results from "pre-feedback" clusters, where the central newly active radio galaxies (age $<10^{3}$ yr) may not yet have had time to alter the thermodynamic state of the ICM. We analyze $Chandra$ and MUSE observations of two such systems, evaluating the hot gas entropy and cooling time profiles, and characterizing the morphology and kinematics of the warm gas. Based on our exploratory study of these two sources, we find that the hot gas meets the expectations for an as-yet unheated ICM. Specifically, the entropy and cooling time of pre-feedback clusters within 20 kpc from the center fall below those of mature-feedback clusters by a factor $\sim$2. We speculate that with an estimated mechanical power of $\sim10^{44} - 10^{45}$ erg s$^{-1}$, the two young radio galaxies may restore the entropy levels in a few tens of Myr, which are typical values of power outbursts and lifetimes for radio galaxies in clusters. Conversely, the properties of the gas at $\sim10^{4}$ K seem to remain invariant between the two feedback stages, possibly suggesting that the warm gas reservoir accumulates over long periods ($10^{7}$ - $10^{8}$ yr) during the growth of the radio galaxy. We conclude that the exploratory results obtained from our analysis of two cluster-central young radio galaxies are crucial in the context of understanding the onset of active galactic nuclei feedback, and they provide enough motivation for further investigation of similar cases.

description: Dickson's Lemma is a simple yet powerful tool widely used in termination proofs, especially when dealing with counters or related data structures. However, most computer scientists do not know how to derive complexity upper bounds from such termination proofs, and the existing literature is not very helpful in these matters. We propose a new analysis of the length of bad sequences over (N^k,\leq) and explain how one may derive complexity upper bounds from termination proofs. Our upper bounds improve earlier results and are essentially tight.

description: We report on the first multi-wavelength Swift monitoring campaign performed on SDSS J164100.10+345452.7, a nearby narrow-line Seyfert 1 galaxy formerly known as radio quiet which was recently detected both in the radio (at 37 GHz) and in the $γ$-rays, which hints at the presence of a relativistic jet. During our 20-month Swift campaign, while pursuing the primary goal of assessing the baseline optical/UV and X-ray properties of J1641, we caught two radio flaring episodes, one each year. Our strictly simultaneous multi-wavelength data closely match the radio flare and allow us to unambiguously link the jetted radio emission of J1641. Indeed, for the X-ray spectra preceding and following the radio flare a simple absorbed power-law model is not an adequate description, and an extra absorption component is required. The average spectrum of J1641 can be best described by an absorbed power law model with a photon index $Γ=1.93\pm0.12$, modified by a partially covering neutral absorber with a covering fraction $f=0.91_{-0.03}^{+0.02}$. On the contrary, the X-ray spectrum closest to the radio flare does not require such extra absorber and is much harder ($Γ_{\rm flare} \sim 0.7\pm0.4$), thus implying the emergence of a further, harder spectral component. We interpret this as the jet emission emerging from a gap in the absorber. The fractional variability we derive in the optical/UV and X-ray bands are found to be lower than the typical values reported in the literature, since our observations of J1641 are dominated by the source being in a low state. Under the assumption that the origin of the 37 GHz radio flare is the emergence of a jet from an obscuring screen also observed in the X-rays, the derived total jet power is $P^{\rm tot}_{\rm jet}=3.5\times10^{42}$ erg s$^{-1}$, comparable to the lowest measured in the literature.

We introduced triangular-shaped ferromagnetic bond disorder in the S=1 bilinear-biquadratic model on a triangular lattice. It is shown that the coupling between the impurity magnetic moment and nonmagnetic excitation in the bulk yields single-moment anisotropy and long-range anisotropic interaction between impurity magnetic moments. This interaction can induce unconventional spin-freezing phenomena observed in triangular magnet, NiGa2S4.

description: Designs for screening experiments usually include factors with two levels only. Adding a few four-level factors allows for the inclusion of multi-level categorical factors or quantitative factors with possible quadratic or third-order effects. Three examples motivated us to generate a large catalog of designs with two-level factors as well as four-level factors. To create the catalog, we considered three methods. In the first method, we select designs using a search table, and in the second method, we use a procedure that selects candidate designs based on the properties of their projections into fewer factors. The third method is actually a benchmark method, in which we use a general orthogonal array enumeration algorithm. We compare the efficiencies of the new methods for generating complete sets of non-isomorphic designs. Finally, we use the most efficient method to generate a catalog of designs with up to three four-level factors and up to 20 two-level factors for run sizes 16, 32, 64, and 128. In some cases, a complete enumeration was infeasible. For these cases, we used a bounded enumeration strategy instead. We demonstrate the usefulness of the catalog by revisiting the motivating examples.

description: We investigate possible symmetry properties of the scalar sector of Multi-Higgs-Doublet Models, and, to some extent, the generalization of such models to gauge groups other than $SU(2)_L\times U(1)_Y$. In models where the ${\cal C}$ (charge conjugation) violating operator $\hat{C}$ is not present, the scalar potential is invariant under a group larger than the gauge group, O(4) when the Higgs fields are doublets. If the Higgs fields develop aligned vacuum expectation values, this symmetry will break to an O(3) subgroup, which in general is further broken by loop corrections involving the gauge bosons. Assuming such corrections are small, the physical properties of the Higgs sector will approximately organize into representations of SO(3). If the vacuum expectation values of the Higgs fields are aligned in the direction of the ${\cal C}$ even fields, the mass spectra of the charged and ${\cal C}$ odd sectors will be degenerate. Moreover, if the Higgs fields develop a pair of non-aligned vacuum expectations values, so that the charge conjugation symmetry is spontaneously broken (but not the U(1) electromagnetic gauge invariance), a pair of light charged Higgs bosons should appear.

description: Context: this paper describes the detection of wide binary and multiple central stars (CSs) of Galactic planetary nebulae (PNe) using the most up-to-date data available from the Gaia Data Release 3 (Gaia DR3). Aims: the objective of this study is to benefit from the Gaia DR3's reliable measurements of parallax and proper motion to reveal the binary, ternary, and quadruple CSs of planetary nebulae. Methods: in our search for the binary and multiple CSs in the Gaia archive, we adopted the criteria provided in the literature to ensure that the CS and its partner(s) have comparable parallaxes and proper motions. Results: we have detected a total of 45 binary and multiple stellar systems coupled with the CSs of PNe. Based on the standard error of the parallax, this sample was divided into four categories: highest probable, probable, possible, and uncertain systems, which comprise 18, 8, 10, and 9 objects, respectively. Except for A35, NGC246 and IC 3568, the radial velocities of the CSs companions are unknown for our PNe sample. The radial velocity measurements of these three companion stars are comparable to their linked CSs. The results show the detection of a highly probable quadruple system, and a probable quadruple system: NGC6853 and PHRJ1129-6012, respectively. In addition, we found one highly probable (Fr 2-42), one probable (M 1-58) and two possible (IC 2553 and PHRJ1123-6030) ternary CS systems. The results further show that the primary components of eight wide and very wide binary systems are actually close binary systems. Moreover, the masses of the components of nine PN binary and multiple wide systems were calculated.

description: We show that the hybrid inflation is naturally realized in the framework of a supersymmetric axion model, which is consistent with the WMAP observation if the Peccei-Quinn symmetry breaking scale is around 10^{15}GeV. By solving the post inflationary scalar dynamics, it is found that the scalar partner of the axion, saxion, oscillates with large amplitude and its decay produces a huge entropy and dilutes the axion. As a result, the axion coherent oscillation can be the dominant component of the dark matter in the Universe. Cosmological gravitino and axino problems are solved.

Topological and disorder corrections to the transverse Wiedemann-Franz law and Mott relation in kagome magnets

description: The Wiedemann-Franz law and Mott relation are textbook paradigms on the ratios of the thermal and thermoelectric conductivities to electrical conductivity, respectively. Deviations from them usually reveal insights for intriguing phases of matter. The recent topological kagome magnets TbMn$_6$Sn$_6$ and Mn$_3$Ge show confusingly opposite derivations in the Hall measurement. We calculate the topological and disorder corrections to the Wiedemann-Franz law and Mott relation for the Hall responses in topological kagome magnets. The calculation indicates the dominance of the topological correction in the experiments. More importantly, we derive analytic correction formulas, which can universally capture the two opposite experiments with the chemical potential as the only parameter and will be a powerful guidance for future explorations on the magnetic topological matter.

The role of the chromospheric magnetic canopy in the formation of a sunspot penumbra

description: While it is being conjectured that a chromospheric canopy plays a role in penumbra formation, it has been difficult to find observational evidence of the connectivity between the photosphere and the chromosphere. We investigate the existence of a chromospheric canopy as a necessary condition for the formation of a penumbra and aim to find the origin of the inclined magnetic fields. Spectropolarimetric observations of NOAA AR 12776 from the GRIS@GREGOR instrument were analyzed. Atmospheric parameters were obtained from the deep photospheric Ca I 10839 Å line (VFISV inversion code), the mostly photospheric Si I 10827 Å line (SIR inversion code) and the chromospheric He I 10830 Å triplet (HAZEL inversion code). In the deepest atmospheric layers, we find that the magnetic properties (inclination and field strength distribution) measured on the sunspot sector with fully fledged penumbra are similar to those measured on the sector without penumbra. Yet, in higher layers, magnetic properties are different. In the region showing no penumbra, almost vertical chromospheric magnetic fields are observed. Additionally, thin filamentary structures with a maximum width of 0.1 arcsec are seen in photospheric high-resolution TiO-band images in this region. The existence of a penumbra is found to be discriminated by the conditions in the chromosphere. This indicates that a chromospheric canopy is a necessary condition for the formation of a penumbra. However, our results demonstrate that inclined fields in the chromospheric canopy are not needed for the development of inclined fields in the photosphere. We question the `fallen-magnetic-flux-tubes' penumbra formation scenario and favor a scenario, in which inclined fields emerge from below the surface and are blocked by the overlying chromospheric canopy.

Tuning microwave losses in superconducting resonators

description: Performance of superconducting resonators, particularly cavities for particle accelerators and micro cavities and thin film resonators for quantum computations and photon detectors has been improved substantially by recent materials treatments and technological advances. As a result, the niobium cavities have reached the quality factors $Q\sim 10^{11}$ at 1-2 GHz and 1.5 K and the breakdown radio-frequency (rf) fields $H$ close to the dc superheating field of the Meissner state. These advances raise the question whether the state-of-the-art cavities are close to the fundamental limits, what these limits actually are, and to what extent the $Q$ and $H$ limits can be pushed by the materials nano structuring and impurity management. These issues are also relevant to many applications using high-Q thin film resonators, including single-photon detectors and quantum circuits. This topical review outlines basic physical mechanisms of the rf nonlinear surface impedance controlled by quasiparticles, dielectric losses and trapped vortices, as well as the dynamic field limit of the Meissner state. Sections cover ways of engineering an optimum quasiparticle density of states and superfluid density to reduce rf losses and kinetic inductance by pairbreaking mechanisms related to magnetic impurities, rf currents, and proximity-coupled metallic layers at the surface. A section focuses on mechanisms of residual surface resistance which dominates rf losses at ultra low temperatures. Microwave losses of trapped vortices and their reduction by optimizing the concentration of impurities and pinning potential are also discussed.

Publisher: name: University of British Columbia

description: Purification and characterization of membrane proteins is often limited by the ability to reconstitute membrane proteins into a soluble state with a membrane mimetic, while ensuring the protein is in a native state. Here we present a method to stabilize the entire E. coli membrane proteome into a soluble state using the peptidisc library, simultaneously purify a target protein, as well as verify native conformation of the target utilizing a native ligand of the target membrane protein. We purify two β-barrels, the ferrichrome receptor FhuA, and the vitamin B-12 receptor BtuB, as well as three α-helical protein complexes, the inner membrane translocon SecYEG, and the expanded holo-translocon (HTL), and a novel expanded holo-translocon we term the HMD complex. We purify these proteins with native ligands and antibodies in a highly pure and soluble state, as well as identify native interactors via mass spectrometry analysis. This is the first time any of these proteins have been purified via their native ligands, in a soluble state in the absence of detergent, as well as the first time the HMD complex has been isolated. This offers a rapid methodology to fish for target membrane proteins in soluble, native states.

description: In view of the precise data available on inclusive polarized electron scattering off polarized proton targets in the nucleon resonance excitation region, we compare these results with the coherent sum of resonant contributions to the polarized structure function $g_1$ and virtual photon asymmetry $A_1$. To this goal, we employ the nucleon resonance electroexcitation amplitudes determined for photon virtualities $Q^2$ $<$ 5.0 GeV$^2$ from analyses of the CLAS data on exclusive electroproduction off protons in the resonance region. Most of the well established resonances of four star PDG status in the mass range up to 1.75~GeV are included. We find that the resonance-like structures observed in the inclusive $g_1$ data are related to the resonant contributions in the entire range of photon virtuality $Q^2$ where the data on $g_1$ are available. In the range of invariant mass of the final hadron system $W$ $>$ 1.5 GeV, the data on the asymmetry $A_1$ are well reproduced even when accounting for resonant contributions only, especially for the larger values of $Q^2$ and energies analysed. This observation offers an interesting hint to quark-hadron duality seen in polarized inclusive electron scattering observables.
