description: Quantum oxide materials possess a vast range of properties stemming from the interplay between the lattice, charge, spin and orbital degrees of freedom, in which electron correlations often play an important role. Historically, the spin-orbit coupling was rarely a dominant energy scale in oxides. It however recently came to the forefront, unleashing various exotic phenomena connected with real and reciprocal-space topology that may be harnessed in spintronics. In this article, we review the recent advances in the new field of oxide spin-orbitronics with a special focus on spin-charge interconversion from the direct and inverse spin Hall and Edelstein effects, and on the generation and observation of topological spin textures such as skyrmions. We highlight the control of spin-orbit-driven effects by ferroelectricity and give perspectives for the field.

description: Off-farm income is a permanent, significant component of total income for many farm households. In 1986, half of all farm households depended mainly on off-farm income for family living expenses, while two-fifths depended primarily on farm income. Less than a tenth of the households depended on both farm and off-farm income. Farm commodity programs are important in maintaining income levels for many farm households, but those that depend primarily on off-farm income probably receive greater benefits from policies designed to initiate and maintain growth in the overall economy. This report examines the relative importance of farm and off-farm sources of income by type of farm, farm size, region, and proximity to major metro employment centers.

description: An important aspect of the study of Quark-Gluon Plasma (QGP) in ultra-relativistic collisions of heavy ions is the ability to identify, in experimental data, a subset of the jets that were strongly modified by the interaction with the QGP. In this work, we propose studying deep learning techniques for this purpose. Samples of $Z+$jet events were simulated in vacuum and medium and used to train deep neural networks with the objective of discriminating between medium- and vacuum-like jets. Dedicated Convolutional Neural Networks, Dense Neural Networks and Recurrent Neural Networks were developed and trained, and their performance was studied. Our results show the potential of these techniques for the identification of jet quenching effects induced by the presence of the QGP.

Shock Wave Structure in a Strongly Nonlinear Granular Lattice with Viscous Dissipation

description: The shock wave structure in a one-dimensional lattice (e.g. granular chain) with a power law dependence of force on displacement between particles with viscous dissipation is considered and compared to the corresponding long wave approximation. A dissipative term depending on the relative velocity between neighboring particles is included in the discrete model to investigate its influence on the shape of steady shock profiles. The critical viscosity coefficient is obtained from the long-wave approximation for arbitrary values of the exponent n and denotes the transition from an oscillatory to a monotonic shock profile in stronly nonlinear systems. The expression for the critical viscosity coefficient converges to the known equation for the critical viscosity in the weakly nonlinear case. Values of viscosity based on this expression are comparable to the values obtained in the numerical analysis of a discrete particle lattice with a Herzian contact interaction corresponding to n = 3/2. An initial disturbance in a discrete system approaches a stationary shock profile after traveling a short distance that is comparable to the width of the leading pulse of a stationary shock front. The shock front width is minimized when the viscosity is equal to its critical value.

description: After explaining the motivation for this article, I briefly recapitulate the methods used to determine, somewhat coarsely, the rotation curves of our Milky Way Galaxy and other spiral galaxies, especially in their outer parts, and the results of applying these methods. Recent observations and models of the very inner central parts of galaxian rotation curves are only briefly described. I then present the essential Newtonian theory of (disk) galaxy rotation curves. The next two sections present two numerical simulation schemes and brief results. Application of modified Newtonian dynamics to the outer parts of disk galaxies is then described. Finally, attempts to apply Einsteinian general relativity to the dynamics are summarized. The article ends with a summary and prospects for further work in this area.

Text-music relations in Richard Strauss's Im Abendrot
Creators: name: Parson, Laurel Jeanne
Publisher: name: University of British Columbia
Year: 2012

description: This thesis examines in detail the ways in which music and text relate to and condition each other in Richard Strauss's Im Abendrot (1948), the first of the Vier letzte Iieder. The first chapter consists of an analysis and interpretation of the text itself, a poem written by Joseph von Eichendorff. Interpretation of the poem is based on its place in the context of Eichendorff’s other poetry, as well as on internal details of imagery and structure. An ostensibly slight alteration which Strauss made in the poem produces a significant change of Perspective and tone : in the last line of Eichendorff’s poem--Ist das etwa der Tod?--death is contemplated from adistance; in Strauss's version--Ist dies etwa der Tod?--the narrator stands at its very threshold, anticipating with mixed emotions the profound metamorphosis which is imminent. This reading of the poem is further suggested by Im Abendrot's relation to the texts of the three remaining songs in the cycle, and also by the connections, conceptual as well asmusical, between the Vier letzte Iieder and Strauss's early tone poem, Tod und Verklarung. Subsequent chapters deal with aspects of Strauss’s musical setting as they relate to the text, specifically in the areas of formal/motivic, harmonic, melodic, and metric/rhythmic structure. The concluding material raises some questions, arising as a result of this specific analysis, about the nature of text-music relations in general, and points to potential areas of further. study.

description: The swelling equilibrium of Olympic gels, which are composed of entangled cyclic polymers, is studied by Monte Carlo Simulations. In contrast to chemically crosslinked polymer networks, we observe that Olympic gels made of chains with a \emph{larger} degree of polymerization, $N$, exhibit a \emph{smaller} equilibrium swelling degree, $Q\propto N^{-0.28}ϕ_{0}^{-0.72}$, at the same polymer volume fraction $ϕ_{0}$ at network preparation. This observation is explained by a desinterspersion process of overlapping non-concatenated rings upon swelling.

description: The influence of correlation effects on the orbital moments for transition metals and their alloys is studied by first-principle relativistic Density Functional Theory in combination with the Dynamical Mean-Field Theory. In contrast to the previous studies based on the orbital polarization corrections we obtain an improved description of the orbital moments for wide range of studied systems as bulk Fe, Co and Ni, Fe-Co disordered alloys and 3$d$ impurities in Au. The proposed scheme can give simultaneously a correct dynamical description of the spectral function as well as static magnetic properties of correlated disordered metals.

description: We propose a new type of Josephson junction formed by two superconductors close to the superconductor-Mott-insulator transition, one of which is doped with holes and the other is doped with electrons. A self-organized Mott-insulating depletion region is formed at the interface between two superconductors, giving rise to an asymmetric response of current to the external voltage. The collective excitations of the depletion region result in a novel phase dynamics that can be measured experimentally in the noise spectrum of the Josephson current.

description: A simple Arduino-based potentiostat has been developed. This potentiostat design is cost effective for low budget applications and educational purposes. The resolution and linear response of the developed potentiosat was evaluated. A cyclic voltammetry of potassium ferricyanide K3[Fe(CN)6] was performed to compare the potentiostat electrochemical performance with a commercial one. To show the portable potentiostat capabilities, cyclic voltammograms were also performed at different scan rates. Finally, the diffusion coefficient of potassium ferricyanide was calculated in a solution containing a known concentration of the salt using the Randles-Sevcik equation

description: We investigate a factor that can affect the number of links of a specific stock in a network between stocks created by the minimal spanning tree (MST) method, by using individual stock data listed on the S&P500 and KOSPI. Among the common factors mentioned in the arbitrage pricing model (APM), widely acknowledged in the financial field, a representative market index is established as a possible factor. We found that the correlation distribution, $ρ_{ij}$, of 400 stocks taken from the S&P500 index shows a very similar with that of the Korean stock market and those deviate from the correlation distribution of time series removed a nonlinearity by the surrogate method. We also shows that the degree distribution of the MSTs for both stock markets follows a power-law distribution with the exponent $ζ\sim$ 2.1, while the degree distribution of the time series eliminated a nonlinearity follows an exponential distribution with the exponent, $δ\sim 0.77$. Furthermore the correlation, $ρ_{iM}$, between the degree k of individual stock, $i$, and the market index, $M$, follows a power-law distribution, $ \sim k^γ$, with the exponent $γ_{\textrm{S&P500}} \approx 0.16$ and $γ_{\textrm{KOSPI}} \approx 0.14$, respectively. Thus, regardless of the markets, the indivisual stocks closely related to the common factor in the market, the market index, are likely to be located around the center of the network between stocks, while those weakly related to the market index are likely to be placed in the outside.

The conical flow from quenched jets in sQGP

subject: FOS: Physical sciences

description: Starting with a reminder of what is strongly coupled Quark-Gluon Plasma (sQGP), we proceed to recent advances in jet quenching and heavy quark diffusion, with a brief summary of various results based on AdS/CFT correspondence. The conical flow is a hydrodynamical phenomenon created by energy and entropy deposited by high energy jets propagating in matter, similar in nature to well known sonic boom from the supersonic planes. After a brief review, we discuss excitations of two hydro modes -- sound and ``diffuson'' -- which can be excited in this way. We also study expanding matter case, with a variable sped of sound, and use adiabatic invariants to show that the parameter $v/T$ ($v$ velocity in the wave, $T$ temperature) is increasing, up to a factor 3, during expansion. At the end we discuss recent results of the Princeton group which derived conical flow from AdS/CFT.

description: In this paper, we define a new spinor classification that encompasses the recently proposed spin-half bosons with mass dimension three-half. As it will be shown, these particles, which are governed by a first-order equation and consequently provide a local theory, belong to a specific subclass of class-2 spinors within the bosonic classification, playing a similar role to Dirac spinors within the Lounesto classification. Such bosonic classification is shown to be closely connected with the usual fermionic Lounesto classification, and thus, evincing a symmetry between Dirac fermions and spin-half bosons.

Trends in the Hired Farm Work Force, 1945-87

name: Oliveira, Victor J.
Publisher: name: Unknown
Year: 1989
Subjects: Labor and Human Capital

description: New technology, nonfarm labor conditions, farm prices, and government policies have altered both the size and composition of the hired farm work force. Average annual farm employment dropped 70 percent between 1945 and 1987. Although family members continue to provide the major portion of agricultural labor, hired farmworkers contribute relatively more labor now, 36 percent in 1987 compared with 22 percent in 1945. The numbers of domestic workers and legally admitted foreign nationals doing hired farmwork have stabilized in recent years after wide variations responding to wartime labor shortages, changes in government work programs, and increased mechanization. The number of illegal aliens working in U.S. agriculture is unknown owing to lack of accurate data, but the increase in apprehensions of these aliens after 1965 suggests a large population. The Immigration Reform and Control Act of 1986 will probably significantly influence the composition of the hired farm work force.
Lully's Psyché (1671) and Locke's Psyche (1675) : contrasting national approaches to musical tragedy in the seventeenth century
Creators: name: Wiese, Helen Lloy
Publisher: name: University of British Columbia
Year: 2012

description: The English semi-opera, Psyche (1675), written by Thomas Shadwell, with music by Matthew Locke, was thought at the time of its performance to be a mere copy of Psyche (1671), a French tragedie-ballet by Moliere, Pierre Corneille, and Philippe Quinault, with music by Jean- Baptiste Lully. This view, accompanied by a certain attitude that the French version was far superior to the English, continued well into the twentieth century. This view is misleading; although the English play was adapted from the French, both were representative of two well-developed native theatrical traditions. Therefore, though there are certain parallels, both in plot and in the subject matter of some musical numbers, the differences in structure, both of the drama and of the music, are more significant. This thesis is a comparative study of the two plays, analyzing both their dramatic and musical structures, and examining them both from the context of the two theatrical traditions. It is concluded that the literary approach to tragedy of French theater resulted in the separation of drama and music, the latter relegated to the prologue, or to end-of-act diversions called intercedes. This allowed Lully to have great control over his music, and in Psyche (1671), he was concerned with the form of each intermede as a whole instead of striving for a variety of forms and ensembles within individual songs. Most of his songs and dances are solo airs in binary form; he makes little use of chorus and ensembles. On the contrary, the music in Psyche (1675) on many occasions was integrated with the plot, and was scattered randomly throughout the play. This prevented Locke from having artistic control over his compositions; Shadwell, the lyricist, determined where the music would occur, the ensembles to be used, and the moods of songs. Shadwell and Locke were concerned with the variety in each individual piece, rather than with unifying the overall form of musical scenes, and the overwhelming majority of songs have a combination of solo voice, ensembles, and chorus. Therefore, Psyche is not an unoriginal copy, but is a reinterpretation of the myth using the aesthetic of the Restoration tragic theater.
The importance of historic pollards for livestock

description: Presentation by Jill Butler of the Woodland Trust given at the 2018 Farm Woodland Forum meeting held on 10-11th July at the Allerton Project, UK on the importance of historic pollards for livestock Across Europe and into Turkey, trees have been cut as pollards since time immemorial. Different species of tree have been cut in a variety of traditional ways for a whole range of valuable products, but principally for tree 'hay' or fodder, fruits, wood fuel or building materials. From Scandinavia to the Mediterranean, from Portugal to Turkey. Interestingly the practice was not exported to the New World with European immigrants. Tree fodder from pollards helped farmers and commoners offset the risks that they faced from poor summers – principally drought but also high rainfall and long cold winters. Before the coming of oil and plastics they were essential for providing other essential household goods and were on the doorstep. This contrasts with coppice which was often unavailable to local communities as it was used for industrial purposes such as mining and smelting or exported away from the community to growing towns and cities. The importance of the cultural heritage value of the trees should be used to help justify the protection of ancient pollards and their historic landscapes as much as their biodiversity, ecosystem service and tourism values. It should also be used to encourage the establishment and cutting of new pollards to restore or renew traditional landscapes in the same way that historic buildings and archaeological artefacts are conserved for future generations to enjoy.

description: Parafermionic zero modes, $\mathbb{Z}_n$-symmetric generalizations of the well-known $\mathbb{Z}_2$ Majorana zero modes, can emerge as edge states in topologically nontrivial strongly correlated systems displaying fractionalized excitations. In this paper, we investigate how signatures of parafermionic zero modes can be detected by its effects on the properties of a quantum dot tunnel-coupled to a system hosting such states. Concretely, we consider a strongly-correlated 1D fermionic model supporting $\mathbb{Z}_4$ parafermionic zero modes coupled to an interacting quantum dot at one of its ends. By using a combination of density matrix renormalization group calculations and analytical approaches, we show that the dot's zero-energy spectral function and average occupation numbers can be used to distinguish between trivial, $\mathbb{Z}_4$ and $2\times \mathbb{Z}_2$ phases of the system. The present work opens the prospect of using quantum dots as detection tools to probe non-trivial topological phases in strongly correlated systems.

description: Yellowballs (YBs) were first discovered during the Milky Way Project citizen-science initiative (MWP; Simpson et al. 2012). MWP users noticed compact, yellow regions in Spitzer Space Telescope mid-infrared (MIR) images of the Milky Way plane and asked professional astronomers to explain these "yellow balls." Follow-up work by Kerton et al. (2015) determined that YBs likely trace compact photo-dissociation regions associated with massive and intermediate-mass star formation. YBs were included as target objects in a version of the Milky Way Project launched in 2016 (Jayasinghe et al. 2016), which produced a listing of over 6000 YB locations. We have measured distances, cross-match associations, physical properties, and MIR colors of ~500 YBs within a pilot region covering the l= 30 - 40 degrees, b= +/- 1 degree region of the Galactic plane. We find 20-30% of YBs in our pilot region contain high-mass star formation capable of becoming expanding H II regions that produce MIR bubbles. A majority of YBs represent intermediate-mass star-forming regions whose placement in evolutionary diagrams suggest they are still actively accreting, and may be precursors to optically-revealed Herbig Ae/Be nebulae. Many of these intermediate-mass YBs were missed by surveys of massive star-formation tracers and thus this catalog provides information for many new sites of star formation. Future work will expand this pilot region analysis to the entire YB catalog.

description: This work investigates the formation of primordial black holes within a radiation fluid with an anisotropic pressure. We focus our attention on the initial conditions describing cosmological perturbations in the super horizon regime, using a covariant form of the equation of state in terms of pressure and energy density gradients. The effect of the anisotropy is to modify the initial shape of the cosmological perturbations with respect to the isotropic case. Using the dependence of the threshold $δ_\mathrm{c}$ for primordial black holes with respect to the shape of cosmological perturbations, we estimate here how the threshold is varying with respect to the amplitude of the anisotropy. If this variation is large enough it could lead to a significant variation of the abundance of PBHs.

description: It is of extreme importance to monitor and manage the battery health to enhance the performance and decrease the maintenance cost of operating electric vehicles. This paper concerns the machine-learning-enabled state-of-health (SoH) prognosis for Li-ion batteries in electric trucks, where they are used as energy sources. The paper proposes methods to calculate SoH and cycle life for the battery packs. We propose autoregressive integrated modeling average (ARIMA) and supervised learning (bagging with decision tree as the base estimator; BAG) for forecasting the battery SoH in order to maximize the battery availability for forklift operations. As the use of data-driven methods for battery prognostics is increasing, we demonstrate the capabilities of ARIMA and under circumstances when there is little prior information available about the batteries. For this work, we had a unique data set of 31 lithium-ion battery packs from forklifts in commercial operations. On the one hand, results indicate that the developed ARIMA model provided relevant tools to analyze the data from several batteries. On the other hand, BAG model results suggest that the developed supervised learning model using decision trees as base estimator yields better forecast accuracy in the presence of large variation in data for one battery.

description: We prove that twist-3 soft-gluon-pole (SGP) cross section for single spin asymmetries (SSA) is determined by a certain ``primordial'' twist-2 cross section up to kinematic and color factors in the leading order perturbative QCD. In particular, for the processes in which the partonic hard scattering occurs among massless partons, the invariance of the ``primordial'' partonic cross section under scale transformation leads to remarkable simplification of the SGP cross section, reproducing compact form that was recently observed for pion production $p^\uparrow p\to πX$ and direct-photon production $p^\uparrow p\to γX$.

description: Transfer payments (cash or goods, mostly from Government programs, received by individuals for which no work is currently done) are an important source of income in nonmetro areas, accounting for 18.7 percent of annual personal income. Social Security and medical payments account for nearly two-thirds of transfer payments to nonmetro areas. Transfers, which continue even if local employment falls during recessions, may make local economies more stable in the short run. However, nonmetro economies that greatly depend on transfer income may be sensitive to changes in Government programs affecting the payments.
An Ahousat elder's songs : transcription and analysis
Creators: name: Bowles, Kathleen E.
Publisher: name: University of British Columbia

description: This study examines the development of a comprehensive transcription method for Northwest Coast Native music. In the past, ethnomusicologists have presented methodologies which sometimes lacked data useful for present comparative studies. For this reason, research for this study was conducted in the field to gain a more complete understanding of both musical and cultural characteristics. Eighteen songs were recorded for this study between November 1990 and February 1991. They were sung by Mr. Peter Webster, an Ahousat elder of the Central Nuu-chah-nulth people located on Flores Island near Tofino on Vancouver Island, British Columbia. Melodies, drum rhythms and song texts were discussed in depth with Mr. Webster, thus providing many musical and cultural insights from an 'emie' (inside) point of view. Much of this information is included with the song transcriptions and analyses. Song texts are presented in the T'aat'aaqsapa dialect of the Nuu-chah-nulth language, together with English translations, Comparisons are also made with Ida Halpern's 1974 recording, Nootka: Indian Music of the Pacific Northwest to determine the extent of musical continuity and variation over this brief period. One of the limitations of my work has been the lack of opportunity to record songs during the ceremonies in which they are usually performed, such as potlatches or tlukwanas. Another limitation has been the Western notation system, which, as received, is not sufficiently flexible for the transcription of Native music. For this study, additional descriptive signs have beau created to adapt the Native musical characteristics to the Western notation system. While the method developed in this study has facilitated the transcription of Nuu-chah-nulth music, there is still a need for further development of an independent notation system. A clear, comprehensive transcription method, flexible enough to accommodate this music, has been the primary aim of this study. If this transcription method is useful for transcribing other Native musics, then future comparative music studies will benefit from it.

description: This report, Deliverable D5.3 – Report on the Modularization of CEPD and Micro-credentialing, is a key output of Work Package 5 (WP5) of the Modular Continuing Higher Education by Micro-credentials (MCE) project, co-funded by the Erasmus+ programme. MCE aims to support the transformation of European universities by integrating micro-credentials into their lifelong learning offerings, aligning these developments with learner needs, institutional strategies, and evolving European and national policy frameworks. The overarching objective of WP5 is to test modularization and micro-credentialing practicesthrough real-world pilots that reflect the diversity of institutional contexts and learner demands. Within this framework, Task 5.3 specifically addresses the need to monitor and evaluate stakeholder acceptance of micro-credentials—one of the critical success factors for their sustainable uptake and institutional integration. This task contributes directly to the MCE project’s ambition to create an evidence base for policy recommendations (WP6) and to support institutional development (WP3, WP4). To that end, this report presents the methodological approach, data collection tools, and key findings from a large-scale evaluation involving 705 respondents across 22 pilot courses delivered by MCE partner institutions. Stakeholders included students, professors/course designers, higher education institution (HEI) managers, and external stakeholders (e.g., employers and professional organisations). The evaluation was structured around five core dimensions drawn from D5.1: 1. Relative Advantage 2. Compatibility 3. Complexity 4. Trialability 5. Observability Each dimension was operationalised through validated survey items and Likert-scale responses, ensuring consistency across stakeholder groups and institutions. Data were collected with either the Millisecond Inquisit platform or other GDPR-compliant tools to guarantee methodological robustness and compliance with data protection regulations.

description: Solar Orbiter observed an interplanetary coronal mass ejection (ICME) event at 0.8 AU on 2020 April 19. The ICME was also observed by Wind at 1 AU on 2020 April 20. An interplanetary shock wave was driven in front of the ICME. We focus on the transmission of the magnetic fluctuations across the shock and analyze the characteristic wave modes of solar wind turbulence near the shock observed by both spacecraft. The ICME event is characterized by a magnetic helicity based technique. The shock normal is determined by magnetic coplanarity method for Solar Orbiter and using a mixed coplanarity approach for Wind. The power spectra of magnetic field fluctuations are generated by applying both a fast Fourier transform and Morlet wavelet analysis. To understand the nature of waves observed near the shock, we use the normalized magnetic helicity as a diagnostic parameter. The wavelet reconstructed magnetic field fluctuation hodograms are used to further study the polarization properties of waves. We find that the ICME-driven shock observed by Solar Orbiter and Wind is a fast forward oblique shock with a more perpendicular shock angle at 1 AU. After the shock crossing, the magnetic field fluctuation power increases. Most of the magnetic field fluctuation power resides in the transverse fluctuations. In the vicinity of the shock, both spacecraft observe right-hand polarized waves in the spacecraft frame. The upstream wave signatures fall in a relatively broad and low-frequency band, which might be attributed to low-frequency MHD waves excited by the streaming particles. For the downstream magnetic wave activity, we find oblique kinetic Alfven waves with frequencies near the proton cyclotron frequency in the spacecraft frame. The frequency of the downstream waves increases by a factor of 7-10 due to the shock compression and the Doppler effect.
The rhythmic nature of Bill Evans' melodies

description: Jazz composers and scholars have praised American pianist Bill (William John) Evans as a superior improviser. But oddly, considering the renown gained by Evans, his music is only recently being analyzed in any theoretical detail. An essential aspect of Evans' style, in my opinion, is his ability to satisfy the harmonic obligations of the theme and, at the same time, establish a maximum degree of rhythmic contrast with the metrical pattern of the original harmonic succession. This paper examines the rhythmic relationship of Evans' melodies to the chord changes over various timespans of the theme and its variations. A method of accent analysis is developed to describe this relation and is applied to excerpts firm two of his solos with a distinct bebop character. According to the provided criteria, this analytical method defines the strongest melodic accents ("points of emphasis") in the melodic accent pattern in relation to the different chordal accents generated by the theme's harmonic progressions and to a lesser extent by the interpolated substitutes that together constitute the hypermetrical accent pattern. In comparing these accent patterns and the accent processes of "coincidence", "synchronization", "cross-accent", and "convergence" they articulate we determine some of the techniques Evans uses to create rhythmic contrast between the theme and its variations. On the grounds of this study, one may conclude that the rhythmic structures of melody shown to be in "Peri's Scope" and "Beautiful Love" are characteristic of Evans' improvisations, especially in the early stages of his career. Hence, one may use this type of analysis to investigate the improvisational styles of Evans' predecessors: innovators such as Charlie Parker and Bud Powell, and those of some of his contemporaries, such as the pianist Red Garland. Finally, the original concepts, terms, and processes identified by this method of accent analysis may help the jazz student to recognize the possible relations of melodic pitches to underlying chords during the course of performance. It seems likely, then, that this type of analysis can form the basis for a pedagogical method that has a distinctly rhythmic-harmonic aspect, an aspect that deserves more attention in jazz education.

description: A subgraph $H$ of a graph $G$ is isometric if the distances between vertices in $H$ coincide with the distances between the corresponding vertices in $G$. We show that for any integer $n\ge 1$, there is a graph on $3^{n+O(\log^2 n)}$ vertices that contains isometric copies of all $n$-vertex graphs. Our main tool is a new type of distance labelling scheme, whose study might be of independent interest.
