Refleksiv praksislæring i relation til den klassiske læringspsykologi: Del I
Creators: name: Pjengaard, Søren
Publisher: name: CEPRA-striben
Year: 2016

description: Formålet med denne og de efterfølgende to artikler
er at placere UCN’s læringstilgang, Refleksiv praksislæring,
i sammenhæng med de klassiske læringspsykologiske
teorier. Udgangspunktet er, at ingen
nøjagtig ved, hvad der sker socialt, psykologisk,
fysiologisk og adfærdsmæssigt, når læring finder
sted. Mange vil derfor i lighed med undertegnede
advare imod at reducere læring til teknik, metodik,
en bestemt logik og tilhørende evidensresultater.
At beskæftige sig med, hvad, hvordan og hvorfor
mennesker lærer, kalder på ydmyghed, forsigtighed
og en villighed til at lade sig konfrontere med det
videnskabelige paradoks. Grundantagelsen bag
Refleksiv praksislæring er, at det er refleksivt muligt
at skelne mellem forskellige læringsteoretiske
optikker uden at adskillige og afkoble dem helt fra
hinanden, men snarere anvende optikkerne integrativt
og pluralistisk og derigennem lære sammen,
i og af praksis. Artiklerne kan læses hver for sig,
men det største udbytte af læsningen kommer
ved at læse og bearbejde de tre artikler som et
sammenhængende hele.

description: We provide an analytic derivation of the bifurcation conditions for localized bulging in an inflated hyperelastic tube of arbitrary wall thickness and axisymmetric necking in a hyperelastic sheet under equibiaxial stretching. It has previously been shown numerically that the bifurcation condition for the former problem is equivalent to the vanishing of the Jacobian determinant of the internal pressure $P$ and resultant axial force $N$, with each of them viewed as a function of the azimuthal stretch on the inner surface and the axial stretch. This equivalence is established here analytically. For the latter problem for which it has recently been shown that the bifurcation condition is not given by a Jacobian determinant equal to zero, we explain why this is the case and provide an alternative interpretation.

description: We construct all (2+1)-dimensional PDEs depending only on 2nd-order derivatives of unknown which have the Euler-Lagrange form and determine the corresponding Lagrangians. We convert these equations and their Lagrangians to two-component forms and find Hamiltonian representations of all these systems using Dirac's theory of constraints. We consider three-parameter integrable equations that are cubic in partial derivatives of the unknown applying our method of skew factorization of the symmetry condition. Lax pairs and recursion relations for symmetries are determined both for one-component and two-component forms. For cubic three-parameter equations in the two-component form we obtain recursion operators in $2\times 2$ matrix form and bi-Hamiltonian representations, thus discovering three new bi-Hamiltonian (2+1) systems.

description: We identify and describe how intense short light pulses couple to massless Dirac fermions in two-dimensional systems. The ensuing excitation dynamics exhibits unusual scaling with the wavelength of the light due the linear dispersion of the band structure and the fact that light coupling is efficient only close to the Dirac points. We exploit these features to achieve valley polarization of more than 70 % with simple pulse shapes. Quantitative results are given for pristine graphene.

description: With the widely used method of correlation matrix analysis, this study reveals the change of traffic states on parallel motorways in North Rhine-Westphalia, Germany. In terms of the time series of traffic flow and velocity, we carry out a quantitative analysis in correlations and reveal a high level of strongly positive traffic flow correlation and rich structural features in the corresponding correlation matrices. The strong correlation is mainly ascribed to the daily time evolution of traffic flow during the periods of rush hours and non-rush hours. In terms of free flow and congestion, the structural features are able to capture the average traffic situation we derive from our data. Furthermore, the structural features in correlation matrices for individual time periods corroborate our results from the correlation matrices regarding a whole day. The average correlations in traffic flows and velocities over all pairwise sections disclose the traffic behavior during each individual time period. Our contribution uncovers the potential application of correlation analysis on the study of traffic networks as a complex system.

description: Entangling gates in trapped-ion quantum computing have primarily targeted stationary ions with initial motional distributions that are thermal and close to the ground state. However, future systems will likely incur significant non-thermal excitation due to, e.g., ion transport, longer operational times, and increased spatial extent of the trap array. In this paper, we analyze the impact of such coherent motional excitation on entangling-gate error by performing simulations of Molmer-Sorenson (MS) gates on a pair of trapped-ion qubits with both thermal and coherent excitation present in a shared motional mode at the start of the gate. We discover that a small amount of coherent displacement dramatically erodes gate performance in the presence of experimental noise, and we demonstrate that applying only limited control over the phase of the displacement can suppress this error. We then use experimental data from transported ions to analyze the impact of coherent displacement on MS-gate error under realistic conditions.

Refleksive rum og formativ evaluering i undervisning
Creators: name: Christensen, Torben Spanget
Publisher: name: CEPRA-striben
Year: 2016

description: Artiklen er inddelt i to hovedafsnit, som hver giver et perspektiv på refleksion og formativ evaluering i undervisningen. Første del handler om indhold i det refleksive rum og om begrundelserne herfor. Evaluering og refleksion skal handle om noget, idet det ellers er en meningsløs aktivitet, og i skolesammenhæng skal det selvfølgelig handle om faglig læring og tilegnelse af kompetencer. Den måde, evaluering og refleksion får næring på, er via feedback fra lærer til elev og omvendt og feedback mellem eleverne indbyrdes. Artiklen vil behandle disse feedbackprocesser. Endelig er bedømmelse et væsentligt aspekt ved refleksion og evaluering. Bedømmelse er en summativ evaluering af en elevs faglige standpunkt eller en elevs arbejdsproces. Hvis bedømmelsen indgår løbende i undervisningen og ikke har form af karaktergivning, men er en formuleret og udfoldet respons, kan man også tale om formativ bedømmelse. Anden del gennemgår i hovedtræk et forskningsprojekt om den fagligt evaluerende lærer-elevsamtale, der i praksis arbejder med evaluering, refleksion, feedback og bedømmelse og kan ses som et forsøg på at opbygge et refleksionsrum i undervisningens praksis.

Om forholdet mellem evaluering med formative og summative formål
Creators: name: Harlen, Wynne
Publisher: name: CEPRA-striben
Year: 2016

description: Denne artikel diskuterer forholdet mellem evaluering med to af
dets hovedformål – at støtte læring og at opsummere det lærte.
Begge formål er centrale i en effektiv uddannelsespraksis, men der
er aspekter, der drejer sig om, hvorvidt det er brugbart at anse dem
for at være begrebsmæssigt og pragmatisk adskilte. Som udgangspunkt
for denne diskussion vil første del af kapitlet fremstille denne
skelnen ved hjælp af modeller for evaluering til læring og evaluering
af læring. Anden og tredje del behandler spørgsmål om, hvorvidt
dokumentation, der er indsamlet til det ene formål, kan bruges
til det andet. Den fjerde del overvejer, om der er en skala
af formål frem for et modsætningspar, og om denne
distinktion mellem formativ og summativ evaluering
er brugbar eller redundant. I en tid hvor praksis først
lige er ved at indhente teori i relation til formativ
evaluering, er det uundgåeligt, at dette kapitel
vil stille flere spørgsmål, end det
besvarer. Slutteligt vil det konkludere,
at distinktionen mellem
formative og summative
formål med evaluering for
nuværende bør opretholdes,
mens evalueringssystemer
bør inkludere visse forholdsregler,
der gør det muligt at
bruge dokumentation, der er
indsamlet af lærere, til begge
formål. Det skal understreges, at
begreberne ’formativ evaluering’
og ’summativ evaluering’ og ’evaluering
til læring’ og ’evaluering af læring’
bruges synonymt i dette kapitel.

Relative distribution of dark matter, gas, and stars around cosmic filaments in the IllustrisTNG simulation

description: We present a comprehensive study of the distribution of matter around different populations of large-scale cosmic filaments, using the IllustrisTNG simulation at z=0. We computed the dark matter (DM), gas, and stellar radial density profiles of filaments, and we characterise the distribution of the baryon fraction in these structures. We find that baryons exactly follow the underlying DM distribution only down to r~7 Mpc to the filament spines. At shorter distances (r<7 Mpc), the baryon fraction profile of filaments departs from the cosmic value $Ω_\mathrm{b} / Ω_\mathrm{m}$. While in the r~0.7-7 Mpc radial domain this departure is due to the radial accretion of the warm-hot intergalactic medium (WHIM) towards the filament cores (creating an excess of baryons with respect to the cosmic fraction), the cores of filaments (r<0.7 Mpc) show a clear baryon depletion instead. The analysis of the efficiency of active galactic nuclei (AGN) feedback events in filaments reveals that they are potentially powerful enough to eject gas outside of the gravitational potential wells of filaments. We show that the large-scale environment (i.e. denser versus less dense, hotter versus colder regions) has a non-negligible effect on the absolute values of the DM, gas, and stellar densities around filaments. Nevertheless, the relative distribution of baryons with respect to the underlying DM density field is found to be independent of the filament population. Finally, we provide scaling relations between the gas density, temperature, and pressure for the different populations of cosmic filaments. We compare these relations to those pertaining to clusters of galaxies, and find that these cosmic structures occupy separate regions of the density-temperature and density-pressure planes.

Grid-based calculations of redshift-space matter fluctuations from perturbation theory: UV sensitivity and convergence at the field level

description: Perturbation theory (PT) has been used to interpret the observed nonlinear large-scale structure statistics at the quasi-linear regime. To facilitate the PT-based analysis, we have presented the GridSPT algorithm, a grid-based method to compute the nonlinear density and velocity fields in standard perturbation theory (SPT) from a given linear power spectrum. Here, we further put forward the approach by taking the redshift-space distortions into account. With the new implementation, we have, for the first time, generated the redshift-space density field to the fifth order and computed the next-to-next-to-leading order (2 loop) power spectrum and the next-to-leading order (1 loop) bispectrum of matter clustering in redshift space. By comparing the result with corresponding analytical SPT calculation and $N$-body simulations, we find that the SPT calculation (A) suffers much more from the UV sensitivity due to the higher-derivative operators and (B) deviates from the $N$-body results from the Fourier wavenumber smaller than real space $k_{\rm max}$. Finally, we have shown that while Padé approximation removes spurious features in morphology, it does not improve the modeling of power spectrum and bispectrum.

Approaching the theoretical limit in quantum gate decomposition
Creators: name: Rakyta, Péter

Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this work we propose a novel numerical approach to decompose general quantum programs in terms of single- and two-qubit quantum gates with a $CNOT$ gate count very close to the current theoretical lower bounds. In particular, it turns out that $15$ and $63$ $CNOT$ gates are sufficient to decompose a general $3$- and $4$-qubit unitary, respectively, with high numerical accuracy. Our approach is based on a sequential optimization of parameters related to the single-qubit rotation gates involved in a pre-designed quantum circuit used for the decomposition. In addition, the algorithm can be adopted to sparse inter-qubit connectivity architectures provided by current mid-scale quantum computers, needing only a few additional $CNOT$ gates to be implemented in the resulting quantum circuits.

description: We describe a technique, applicable to liquid-argon-based dark matter detectors, allowing for discrimination of alpha-decays in detector regions with incomplete light collection from nuclear-recoil-like events. Nuclear recoils and alpha events preferentially excite the liquid argon (LAr) singlet state, which has a decay time of ~6 ns. The wavelength-shifter TPB, which is typically applied to the inside of the active detector volume to make the LAr scintillation photons visible, has a short re-emission time that preserves the LAr scintillation timing. We developed a wavelength-shifting polymeric film - pyrene-doped polystyrene - for the DEAP-3600 detector and describe the production method and characterization. At liquid argon temperature, the film's re-emission timing is dominated by a modified exponential decay with time constant of 279(14) ns and has a wavelength-shifting efficiency of 46.4(2.9) % relative to TPB, measured at room temperature. By coating the detector neck (a region outside the active volume where the scintillation light collection efficiency is low) with this film, the visible energy and the scintillation pulse shape of alpha events in the neck region are modified, and we predict that through pulse shape discrimination, the coating will afford a suppression factor of O($10^{5}$) against these events.

Frugal $U(1)_X$ models with non-minimal flavor violation for $b \to s \ell \ell$ anomalies and neutrino mixing

description: We analyze the class of models with an extra $U(1)_X$ gauge symmetry that can account for the $b \to s \ell \ell$ anomalies by modifying the Wilson coefficients $C_{9e}$ and $C_{9μ}$ from their standard model values. At the same time, these models generate appropriate quark mixing, and give rise to neutrino mixing via the Type-I seesaw mechanism. Apart from the gauge boson $Z'$, these frugal models only have three right-handed neutrinos for the seesaw mechanism, an additional $SU(2)_L$ scalar doublet for quark mixing, and a SM-singlet scalar that breaks the $U(1)_X$ symmetry. This set-up identifies a class of leptonic symmetries, and necessitates non-zero but equal charges for the first two quark generations. If the quark mixing beyond the standard model were CKM-like, all these symmetries would be ruled out by the latest flavor constraints on Wilson coefficients and collider constraints on $Z'$ parameters. However, we identify a single-parameter source of non-minimal flavor violation that allows a wider class of $U(1)_X$ symmetries to be compatible with all data. We show that the viable leptonic symmetries have to be of the form $L_e \pm 3 L_μ- L_τ$ or $L_e - 3 L_μ+ L_τ$, and determine the $(M_{Z^\prime}, g_{Z^\prime})$ parameter space that may be probed by the high-luminosity data at the LHC.

A Statistical Detection of Wide Binary Systems in the Ultra-Faint Dwarf Galaxy Reticulum II

description: Binary stars can inflate the observed velocity dispersion of stars in dark matter dominated systems such as ultra-faint dwarf galaxies (UFDs). However, the population of binaries in UFDs is poorly constrained by observations, with preferred binary fractions for individual galaxies ranging from a few percent to nearly unity. Searching for wide binaries through nearest neighbor (NN) statistics (or the two-point correlation function) has been suggested in the literature, and we apply this method for the first time to detect wide binaries in a UFD. By analyzing the positions of stars in Reticulum II (Ret II) from Hubble Space Telescope images, we search for angularly resolved wide binaries in Ret II. We find that the distribution of their NN distances shows an enhancement at projected separations of $<1$ arcsec relative to a model containing no binaries. We show that such an enhancement can be explained by a wide~binary fraction of $f_b\approx0.007^{+0.008}_{-0.003}$ at separations of more than 3000 AU. Under the assumption that the binary separation distribution is similar to that in the Milky Way, the total binary fraction in Ret II may be on the order of 50%. We also use the observed magnitude distribution of stars in Ret II to constrain the initial mass function over the mass range $0.34-0.78~M_{\odot}$, finding that a shallow power-law slope of $1.01 \le α\le 1.15$ matches the data.

til, at de svageste elever i skolen løftes til gavn for

description: Artiklen præsenterer en analyse af dele af resultaterne
fra et fireårigt forskningsprojekt gennemført
2009 – 2013 omhandlende evaluering i folkeskolen
og implementeringen af de nationale test. Med inddragelse
af Bernsteins teori om pædagogiske modeller
samt empiri fra projektet analyseres testenes
konstitutive virkninger i forhold til undervisningen
og deres betydninger for eleverne.
Analysen viser, at testene kan have virkninger, som
står i modsætning til de intentioner deres introduktion
blev begrundet med, og at dette blandt andet
kan forstås med reference til deres summative design.
Elevernes måder at forstå deres egne testresultater
var præget af en orientering mod præstation og
hierarki. Dette problematiseres.

Nationale test – Ønskede egenskaber og indfriede krav?
Creators: name: Allerup, Peter
Publisher: name: CEPRA-striben
Year: 2016

description: De danske nationale test fulde navn er egentlig ”De Nationale It-baserede Adaptive Obligatoriske Test”. Det fulde navn fremhæver, til forskel fra det forkortede, flere vigtige sider af disse test i sammenligning med mange andre typer af test. Altså nogle signaler om, hvad der gør netop disse test specielle. Testene er resultatet af nogle krav om udvikling af nye evalueringsinstrumenter, som fandt sted for ca. 15 år siden, og i dag indgår testene rutinemæssigt i skolens hverdag. Derfor er det også et passende tidspunkt at spørge, om nogle af de krav og intentioner, der oprindeligt lå bag ved udviklingen, faktisk er blevet indfriet og kan demonstreres opfyldt gennem egenskaber, som man kan undersøge via indsamlede data i dag. Denne artikel har til formål at beskrive et par af de oprindelige krav: Sammenlignelighed af testresultater, adaptiv-itet i forhold til elevers færdighedsniveau og evne til at formidle brugbare evalueringsresultater – set i lys af deres aktualitet i den pædagogiske verden dengang og nu. Vi kan med et kik over skulderen i dag spørge, om det blev, som vi ønskede og krævede det – eller om der mangler noget?

description: De nationale test har fået en ny rolle som grundlag for vurderingen af skolens succes. Dermed flyttes fokus fra folkeskolens brede dannelseshorisont, som den kommer til udtryk i fx formålsparagraffen, og i denne artikel vil jeg identificere 4 afledte, potentielle problemer ved udviklingen. Problemerne er ikke skarpt adskilte, men viser på hver sin måde en væsentlig pædagogisk faldgrube. Slutteligt vil jeg skitsere et bud på, hvordan evalueringsforskning kan være med til at vende denne udvikling således, at skolen – og ikke mindst dens pædagogiske praksis – kan opfattes som byggende på nogle formål, der har værdi i sig selv.

description: The eFEDS survey is a proof-of-concept mini-survey designed to demonstrate the survey science capabilities of SRG/eROSITA. It covers an area of 140 square degrees where 542 galaxy clusters have been detected out to a redshift of 1.3. The eFEDS field is partly embedded in the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) S19A data release, which covers 510 square degrees, containing approximately 36 million galaxies. This galaxy catalogue is used to construct a sample of 180 shear-selected galaxy clusters. In the common area to both surveys, about 90 square degrees, we investigate the effects of selection methods in the galaxy cluster detection by comparing the X-ray selected, eFEDS, and the shear-selected, HSC-SSP S19A, galaxy cluster samples. There are 25 shear-selected clusters in the eFEDS footprint. The relation between X-ray bolometric luminosity and weak-lensing mass is investigated, and it is found that the normalization of the bolometric luminosity and mass relation of the X-ray selected and shear-selected samples is consistent within $1σ$. Moreover, we found that the dynamical state and merger fraction of the shear-selected clusters is not different from the X-ray selected ones. Four shear-selected clusters are undetected in X-rays. A close inspection reveals that one is the result of projection effects, while the other three have an X-ray flux below the ultimate eROSITA detection limit. Finally, 43% of the shear-selected clusters lie in superclusters. Our results indicate that the scaling relation between X-ray bolometric luminosity and true cluster mass of the shear-selected cluster sample is consistent with the eFEDS sample. There is no significant population of X-ray underluminous clusters, indicating that X-ray selected cluster samples are complete and can be used as an accurate cosmological probe.

Doping a moiré Mott Insulator: A t-J model study of twisted cuprates

description: We theoretically investigate twisted structures where each layer is composed of a strongly correlated material. In particular, we study a twisted t-J model of cuprate multilayers within the slave-boson mean field theory. This treatment encompasses the Mott physics at small doping and self consistently generates d-wave pairing. Furthermore, including the correct inter-layer tunneling form factor consistent with the symmetry of the Cu $d_{x^2-y^2}$ orbital proves to be crucial for the phase diagram. We find spontaneous time reversal (T) breaking around twist angle of $45^\circ$, although only in a narrow window of twist angles. Moreover, the gap obtained is small and the Chern number vanishes, implying a non-topological superconductor. At smaller twist angles, driving an interlayer current however can lead to a gapped topological phase. The energy-phase relation of the interlayer Josephson junction displays notable double-Cooper-pair tunneling which dominates around $45^o$. The twist angle dependence of the Josephson critical current and the Shapiro steps are consistent with recent experiments. Utilizing the moiré structure as a probe of correlation physics, in particular of the pair density wave state, is discussed.

description: Denne studien undersøker 141 norske fem-åringers kunnskap om bokstaver, tall og geometriske figurer. I tillegg beskriver vi likheter og forskjeller mellom barnehagene når det gjelder barnas gjenkjennelse av bokstaver, tall og geometriske figurer. Dataene ble samlet inn gjennom en metode der barna selv løste oppgaver som involverer tall, former og bokstaver via en elektronisk web-portal. Resultater viste at en relativt høy andel av barna i vår studie gjenkjente mange av bokstavene, tallene og de geometriske figurene. Allikevel var det noen variasjoner i utvalget. Spesielt fant vi relativt stor variasjon mellom barnehager. Resultatene er diskutert i forhold til et stadig økt fokus på tidlig intervensjon.

description: The angular orientation of an anisotropic scatterer with cylindrical symmetry in a linearly polarized light field represents an optomechanical librator. Here, we propose and theoretically analyze an optimal measurement scheme for the two angular degrees of freedom of such a librator. The imprecision-backaction product of this scheme reaches the Heisenberg uncertainty limit. Furthermore, we propose and analyze a realistic measurement scheme and show that, in the absence of spinning motion around the symmetry axis, measurement-based ground-state cooling of the rotational degrees of freedom of an anisotropic point scatterer levitated in an optical trap is feasible.
Vurdering af kvalitet: Inklusion som eksempel

description: Pædagogisk kvalitet ses inden for uddannelsesforskningen
og den pædagogiske forskning som
et flerdimensionelt, værdiladet, meningsbærende
og målrettet fænomen (SirajBlatchford & Mayo
2012). Det betyder, at kvalitet i dagtilbuddet dels er
holdbar i betydningen bestandig og kulturgenerel,
men også foranderlig og kontekstuelt påvirkelig.
Dermed er kvalitet ikke endegyldig, og at enes om
en endegyldig definition er hverken muligt eller
attråværdigt (Sheridan 2012, 36). Således mener
den svenske kvalitetsforsker Sonja Sheridan, at man
skal medregne både den såkaldte objektivistiske
tilgang til kvalitet, hvor der opereres med et sæt af
målbare karakteristika og den relativistiske tilgang,
hvor den subjektive oplevelse af kvalitet inddrages
(Sheridan 2012).

description: Tendenser som evidensbaseret praksis og løbende
faglig evaluering ændrer måden, den offentlige
sektor styres på. Disse tendenser har fælles forankring
i en forestilling om, at ”sikker viden” skal være
ledetråd for udvikling af velfærdsydelser. ”Sikker
viden” introduceres i artiklen som et nyt styringsprincip
i den offentlige sektor, som er forskelligt fra
mål og resultater, der i årtier har været det dominerende
styringsprincip. Ved at undersøge den nye
folkeskolereform og undervisningsmetoder knyttet
til reformens læringsmål vises, hvordan ”sikker
viden” er blevet et grundlæggende styringsprincip
i folkeskolen. I organiseringen af ”sikker viden”
spiller læringsvejledere en central rolle for at
implementere nye undervisningsmetoder, som
er knyttet til folkeskolereformens læringsmål.
Læringsvejlederen træder således frem i en ny
rolle i folkeskolernes organisation. Det diskuteres,
hvilken betydning læringsve lederen kan have for
relationen mellem lærere og ledelse.

description: The betweenness centrality (BC) is an important quantity for understanding the structure of complex large networks. However, its calculation is in general difficult and known in simple cases only. In particular, the BC has been exactly computed for graphs constructed over a set of $N$ points in the infinite density limit, displaying a universal behavior. We reconsider this calculation and propose an expansion for large and finite densities. We compute the lowest non-trivial order and show that it encodes how straight are shortest paths and is therefore non-universal and depends on the graph considered. We compare our analytical result to numerical simulations obtained for various graphs such as the minimum spanning tree, the nearest neighbor graph, the relative neighborhood graph, the random geometric graph, the Gabriel graph, or the Delaunay triangulation. We show that in most cases the agreement with our analytical result is excellent even for densities of points that are relatively low. This method and our results provide a framework for understanding and computing this important quantity in large spatial networks.

description: The thermal deformation of the critical point action of the 2D tricritical Ising model gives rise to an exact scattering theory with seven massive excitations based on the exceptional $E_7$ Lie algebra. The high and low temperature phases of this model are related by duality. This duality guarantees that the leading and sub-leading magnetisation operators, $σ(x)$ and $σ'(x)$, in either phase are accompanied by associated disorder operators, $μ(x)$ and $μ'(x)$. Working specifically in the high temperature phase, we write down the sets of bootstrap equations for these four operators. For $σ(x)$ and $σ'(x)$, the equations are identical in form and are parameterised by the values of the one-particle form factors of the two lightest $\mathbb{Z}_2$ odd particles. Similarly, the equations for $μ(x)$ and $μ'(x)$ have identical form and are parameterised by two elementary form factors. Using the clustering property, we show that these four sets of solutions are eventually not independent; instead, the parameters of the solutions for $σ(x)/σ'(x)$ are fixed in terms of those for $μ(x)/μ'(x)$. We use the truncated conformal space approach to confirm numerically the derived expressions of the matrix elements as well as the validity of the $Δ$-sum rule as applied to the off-critical correlators. We employ the derived form factors of the order and disorder operators to compute the exact dynamical structure factors of the theory, a set of quantities with a rich spectroscopy which may be directly tested in future inelastic neutron or Raman scattering experiments.

description: В статье рассматривается связь орфографии с другими языковыми уровнями, такими как фонетика, морфология и синтаксис. Орфография, как система правил написания слов, напрямую зависит от фонетического состава языка, структуры морфем и синтаксических конструкций. В статье подчёркивается важность понимания взаимодействия этих уровней для формирования орфографических норм, которые помогают сохранять логичность и структуру языка. Обсуждаются примеры, иллюстрирующие влияние фонетики на орфографию, а также роль морфологии и синтаксиса в определении правил написания слов и употребления знаков препинания. Автор также акцентирует внимание на трудностях и особенностях орфографического нормирования, возникающих в ходе исторического развития языка. Приведены примеры орфографических правил и их соответствия фонетическим, морфологическим и синтаксическим законам.
