description: A complex-valued signal is improper if it is correlated with its complex conjugate. The dimension of the improper signal subspace, i.e., the number of improper components in a complex-valued measurement, is an important parameter and is unknown in most applications. In this letter, we introduce two approaches to estimate this dimension, one based on an information- theoretic criterion and one based on hypothesis testing. We also present reduced-rank versions of these approaches that work for scenarios where the number of observations is comparable to or even smaller than the dimension of the data. Unlike other techniques for determining model orders, our techniques also work in the presence of additive colored noise.

description: Software is a field of rapid changes: the best technology today becomes obsolete in the near future. If we review the graduate attributes of any of the software engineering programs across the world, life-long learning is one of them. The social and psychological aspects of professional development is linked with rewards. In organizations, where people are provided with learning opportunities and there is a culture that rewards learning, people embrace changes easily. However, the software industry tends to be short-sighted and its primary focus is more on current project success; it usually ignores the capacity building of the individual or team. It is hoped that our software engineering colleagues will be motivated to conduct more research into the area of software psychology so as to understand more completely the possibilities for increased effectiveness and personal fulfillment among software engineers working alone and in teams.

description: El presente proyecto de investigación aborda la importancia de integrar a la sociedad civil dentro del proceso de hechura de las Políticas Públicas, a través de mecanismos certeros que fomenten la Participación Ciudadana. Para con ello, contar con ciudadanas y ciudadanos que conozcan ampliamente el contexto en el cual las Políticas Públicas desean incidir, considerando que los gobiernos no siempre cuentan con especialistas en todas las aristas que involucran el trabajo de la gestión administrativa. Tal es el caso de los temas que comprenden a la Migración, donde la participación corresponsable entre gobierno y ciudadanía da fundamento a la identificación de la o las problemáticas sociales y económicas que componen el fenómeno migratorio.El proyecto desglosará las Políticas Públicas que se han implementado en las presentes gestiones de gobierno tanto federal como estatal, y ello, permitirá observar cuál es el panorama de la Migración en el Municipio de Cuautlancingo, Puebla, así como también conocer cuáles han sido las acciones que se han puesto en marcha en un Municipio que a pesar de no ser considerado como de alta migración, está viviendo un incremento gradual de su población migrante y de ingreso de remesas al territorio.

description: We have undertaken a study of the globular cluster (GC) systems of a large sample of elliptical and spiral galaxies in order to test predictions of galaxy formation models. Here we present results for the giant Virgo elliptical NGC 4472 (M49). The galaxy was observed in 3 filters (BVR) using the Mosaic Imager on the Kitt Peak 4-m telescope. Our images roughly double the radial coverage of previous CCD observations of NGC 4472. We have combined the Mosaic data with spectroscopic data and HST data in order to fully characterize the level of contamination in our GC sample. The radial profile of the GC system is fit fairly well by a de Vaucouleurs law out to 17 arc minutes (~80 kpc), but the profile falls slightly below the de Vaucouleurs law between 17 and 23 arc minutes. The bimodal color distribution observed in past studies appears in our data. We find a small metallicity gradient in the inner 8 arc minutes of the GC system due to the increasing ratio of blue to red clusters. The gradient vanishes, however, when the entire radial extent of the data is taken into account. We estimate a total of 5,900 GCs in NGC 4472 out to 23 arc minutes, yielding a specific frequency of 3.6+/-0.6 within this radius. This value is smaller than that found by previous studies of NGC 4472. We examine the implications of these results with regard to predictions made by four galaxy formation models, and find that all four models have at least one inconsistency with the data. [abridged]

description: It is notoriously difficult to localize short $γ$-ray bursts (sGRBs) and their hosts to measure their redshifts. These measurements, however, are critical to constrain the nature of sGRB progenitors, their redshift distribution and the $r$-process element enrichment history of the universe. Here, we present spectroscopy of the host galaxy of GRB111117A and measure its redshift to be $z = 2.211$. This makes GRB111117A the most distant high-confidence short duration GRB detected to date. Our spectroscopic redshift supersedes a lower, previously estimated photometric redshift value for this burst. We use the spectroscopic redshift, as well as new imaging data to constrain the nature of the host galaxy and the physical parameters of the GRB. The rest-frame X-ray derived hydrogen column density, for example, is the highest compared to a complete sample of sGRBs and seems to follow the evolution with redshift as traced by the hosts of long GRBs (lGRBs). The host lies in the brighter end of the expected sGRB host brightness distribution at $z = 2.211$, and is actively forming stars. Using the host as a benchmark for redshift determination, we find that between 43 and 71 per cent of all sGRB redshifts should be missed due to host faintness for hosts at $z\sim2$. The high redshift of GRB111117A is evidence against a lognormal delay-time model for sGRBs through the predicted redshift distribution of sGRBs, which is very sensitive to high-$z$ sGRBs. From the age of the universe at the time of GRB explosion, an initial neutron star (NS) separation of $a_0 < 3.2~R_\odot$ is required in the case where the progenitor system is a circular pair of inspiralling NSs. This constraint excludes some of the longest sGRB formation channels for this burst.

Band structure of a two-dimensional (2D) electron gas in the presence of 2D electric and magnetic modulations and of a perpendicular magnetic field

description: Two-dimensional (2D) periodic electric modulations of a 2D electron gas split each Landau level into the well-known butterfly-type spectrum described by a Harper-type equation multiplied by an envelope function. This equation is slightly modified for 2D magnetic modulations but the spectrum remains qualitatively the same. The same holds if both types of modulations are present. The modulation strengths do not affect the structure of the butterfly-type spectrum, they only change its scale or its envelope. The latter is described by the ratio $α$ of the flux quantum $h/e$ to the flux per unit cell. Exact numerical and approximate analytical results are presented for the energy spectrum as a function of the magnetic field. For integer $α$ the internal structure collapses into a band for all cases. The bandwidth at the Fermi energy depends on the modulation strength, the electron density, and, when both modulations are present, on the phase difference between them. In the latter case if the modulations have a $π/2$ phase difference, the bandwidth at the Fermi energy is nearly independent of the magnetic field and the commensurability oscillations of the diffusive contribution to the resistivity disappear.

Suore, santi, sibille in un processo alla pittura sacra agli esordi del Seicento / Sisters, saints, sibyls in a trial to the sacred painting at the beginning of the 17th century
Creators: name: Moretti, Massimo
Publisher: name: eum
Year: 2019

description: In una chiesa di un monastero di clarisse del ducato di Urbino, nel marzo del 1601, il pittore Giorgio Picchi, in accordo con i sindaci e alcune suore, tenta di distruggere gli affreschi dello stimato Giustino Episcopi, artista della generazione precedente, con la promessa di pitture più allegre e più belle. Interrogato dal tribunale ecclesiastico, Picchi viene accusato di aver violato la clausura e di aver tentato di sostituire delle immagini sacre senza le autorizzazioni previste. I sostenitori lo difesero appellandosi alla convenienza di sostituire le immagini delle sibille con più appropriate figure di santi. Il processo Picchi-Episcopi, come il celebre interrogatorio a Veronese del 1573, è un’indagine sulla pittura sacra dopo il Concilio, sulla condotta del pittore, sui soggetti e sulla maniera di rappresentarli. Attraverso documenti inediti e un confronto con la precettistica del tempo, il contributo, perseguendo un auspicio che fu di Paolo Prodi, intende offrire nuove riflessioni sull’applicazione dei decreti tridentini nelle diocesi particolari. In March 1601, in a church of a monastery of Clarisse in the Duchy of Urbino, the painter Giorgio Picchi, with the support of the mayors and some of the nuns of the convent, tried to destroy the frescoes of the esteemed Giustino Episcopi, an artist of the previous generation. Although Picchi had promised to make more cheerful and beautiful paintings, he was accused for having violated the enclosure and for having tried to replace sacred images without the required authorizations. Some witnesses defended him, appealing to the convenience of replacing the images of the sibyls with more appropriate figures of saints. The Picchi-Episcopi trial, together with the famous interrogation to Veronese in 1573, is not only an investigation on sacred painting after the Council in general, but also on the painter’s behavior, on the paintings’ subjects and on the way of representing them. Through unpublished documents and a comparison with the literature of the time, the essay, pursuing a suggestion by Paolo Prodi, intends to offer new reflections on the application of the Tridentine decrees in the particular dioceses.

description: We report on the critical current density Jc and the vortex dynamics of pristine and 3 MeV proton irradiated (cumulative dose equal to 2x10^16 cm^-2) $β$-FeSe single crystals. We also analyze a remarkable dependence of the superconducting critical temperature Tc, Jc and the flux creep rate S on the sample mounting method. Free-standing crystals present Tc =8.4(1)K, which increases to 10.5(1)K when they are fixed to the sample holder by embedding them with GE-7031 varnish. On the other hand, the irradiation has a marginal effect on Tc. The pinning scenario can be ascribed to twin boundaries and random point defects. We find that the main effect of irradiation is to increase the density of random point defects, while the embedding mainly reduces the density of twin boundaries. Pristine and irradiated crystals present two outstanding features in the temperature dependence of the flux creep rate: S(T) presents large values at low temperatures, which can be attributed to small pinning energies, and a plateau at intermediate temperatures, which can be associated with glassy relaxation. From Maley analysis, we observe that the characteristic glassy exponent μ changes from ~ 1.7 to 1.35-1.4 after proton irradiation.

Subjects: classificationCode: 350713
subject: Project management

description: Oman’s petroleum industry is a high-value economic sector managed by a group of people with distinctly different cultures to the workforce they lead. Since the discovery of oil in the 1970s, Oman’s investment environment has attracted multinational companies. Historically, these companies have imported Western Managers from their headquarters to lead Indian and other blue-collar workers from South Asia. Oman’s national culture and the expatriate’s home country culture combine to create a unique framework within which leaders in the oil and gas construction industry operate. The ability of expatriate managers to lead teams from other cultures affects the delivery of oil and gas projects and government revenue from petroleum product sales. This study explores expectations of leadership from the perspective of blue-collar workers in Oman’s oil and gas construction projects. A quantitative research method was employed to build a greater understanding of the topic. The data was analysed to determine if any of the factors being investigated significantly affect leader effectiveness ratings. The research found that leaders must be autocratic, innovative, control the work, and maintain performance standards to be effective in Oman’s oil and gas construction industry. The implications for Western expatriate leaders are significant. Western leaders are taught to be consultative, to be authentic, to be transformational. To be effective in Oman’s oil and gas construction sector, leaders must be able to adjust their leadership style to match the requirements of the project environment.

description: To identify the optimum conditions for the optical trapping of a droplet under microgravity, we theoretically analyzed the efficiency of trapping with counter laser beams. We found that the distance between the two foci is an important parameter for obtaining stable trapping conditions. We also performed an optical trapping experiment with counter laser beams under microgravity. The experimental results correspond well to the theoretical prediction.

description: Homogeneous wavelets and framelets have been extensively investigated in the classical theory of wavelets and they are often constructed from refinable functions via the multiresolution analysis. On the other hand, nonhomogeneous wavelets and framelets enjoy many desirable theoretical properties and are often intrinsically linked to the refinable structure and multiresolution analysis. In this paper we shall provide a comprehensive study on connecting homogeneous wavelets and framelets to nonhomogeneous ones with the refinable structure. This allows us to understand better the structure of homogeneous wavelets and framelets as well as their connections to the refinable structure and multiresolution analysis.

description: A new method is introduced for characterizing and analyzing materials with random heterogeneous microstructure. The method begins with classifiers which process information from high-fidelity analyses of small-sized simulated microstructures. These classifiers are subsequently used in a multipass moving window to identify subregions of potentially critical microscale behavior such as strain concentrations. In the derivation of the method, it is shown how information theory-based concepts can be formulated in a Bayesian decision theory framework that addresses microstructural issues. Furthermore, it is shown how a sequence of classifiers can be constructed to refine the analysis of microstructure. While the method presented herein is general, a relatively simple example of a two-dimensional, two-phase composite is used to illustrate the analysis steps.

description: In a companion paper, Maiolino et al. (2000) presented various observational evidences for "anomalous" dust properties in the circumnuclear region of AGNs and, in particular, the reduced E(B-V)/N_H and Av/N_H ratios, the absence of the silicate absorption feature in mid-IR spectra of Sy2s and the absence of the carbon dip in UV spectra of reddened Sy1s. In this paper we discuss various explanations for these facts. The observational constraints favor a scenario where coagulation, catalyzed by the high densities in the circumnuclear region, yields to the formation of large grains. The resulting extinction curve is featureless, flatter than Galactic and the E(B-V)/N_H and Av/N_H ratios are significantly reduced. These results should warn about an unappropriate use of the standard Galactic extinction curve and Av/N_H ratio when dealing with the extreme gas conditions typical of the circumnuclear clouds of AGNs. We also investigated alternative scenarios for the observed anomalous properties of dust in AGNs. Some of these scenarios might explain some of the observed properties for a few objects, but they generally fail to account for all of the observational constraints obtained for the large sample of AGNs studied in these works.

description: A general linear stability analysis of simple metal nanowires is presented using a continuum approach which correctly accounts for material-specific surface properties and electronic quantum-size effects. The competition between surface tension and electron-shell effects leads to a complex landscape of stable structures as a function of diameter, cross section, and temperature. By considering arbitrary symmetry-breaking deformations, it is shown that the cylinder is the only generically stable structure. Nevertheless, a plethora of structures with broken axial symmetry is found at low conductance values, including wires with quadrupolar, hexapolar and octupolar cross sections. These non-integrable shapes are compared to previous results on elliptical cross sections, and their material-dependent relative stability is discussed.

Carotid stiffness in an Australian rural community subpopulation: Associations with cardiovascular risk and identifying novel bioengineering changes in advanced computer simulation models

description: Background: Carotid stiffness is a novel biomarker for vascular aging and has been associated with the development and progression of cardiovascular disease. This thesis aims to better understand the mechanisms and parameters of carotid stiffness and explore the interactions between carotid stiffness and other cardiovascular risk factors. In Chapters 1A and 1B, we demonstrate the paucity of data to assess the burden of carotid atherosclerosis in rural populations and the lack of standardised methods to evaluate carotid stiffness. Methods: In Chapters 2A and 2B, we developed a series of software simulations to evaluate the interactions between aortic and carotid stiffness under two different pulse pressure settings. In Chapters 3 and 4, we performed cross-sectional analyses of five-year follow-ups of the participants in the Ararat Health Study, including a carotid ultrasound examination. In Chapter 5, we performed longitudinal analyses of the influence of changes in systolic, mean arterial and pulse pressure and carotid stiffness at a five-year follow-up. Results and discussion: In Chapters 2A and 2B, we found that with the increase of Young’s modulus for the entire aorta and segments of the aortic tree, the deformation, compliance and von Mises stress increase for the aorta and carotid arteries. In Chapter 3, we found associations between multiple carotid stiffness parameters and the presence of carotid plaques. Carotid compliance, distensibility and strain parameters were lower, while β stiffness indices and Ep were higher in participants with carotid plaques than in those without. In Chapter 4, we found that increased IMT was positively associated with prolonged QRS duration. Increased IMT was also positively associated with age, systolic and mean arterial pressure. 19 Furthermore, mean IMT values were higher in participants with QRS > 100 ms compared to participants with QRS ≤ 100 ms. In Chapter 5, we demonstrated the influence of longitudinal changes in systolic, mean arterial and pulse pressure on carotid distensibility and compliance. We report that positive changes or increases in systolic and pulse pressure across five years are associated with lower carotid compliance and distensibility. This work pioneered an understanding of the interactions between aortic stiffness and carotid stiffness and the role of blood pressure changes on carotid stiffness. Another highlight is the need for further rural research on carotid artery disease. Finally, we highlight the need for the correct determination of carotid stiffness measurements that will help ascertain its utility in clinical decision-making.

The recently proposed coarse-grained entropy approach by Brandenberger et. al. is applied to systems which may have a non-zero initial entropy. We find that although the the particle production is amplified as a result of boson statistics, the (coarse-grained) entropy generation is {\em attenuated} when initial particles are present.

description: Radical positions are often inspired by "absolute certainty" (a common situation regarding civil society organizations, without legally formalized public responsibilities, environmental issues and certain minorities, often interconnected) or by the interests of the powerful, formulators and interpreters of the new law. We can see it this month with the absolute failure of the Climate Summit this month, after two-week meeting ended without a crucial agreement in Madrid and the popular phenomena of the phenomena of the teenage activist Greta Thunberg. Global themes are already a reality we have to live with and, in many cases, but not always, until we accept them as correctly motivated. However, this does not mean accepting as certain some debatable measures desired or imposed by great powers, such as the definition of immense natural areas as a "heritage of humanity", possibly compromising the right of peoples to freely dispose of their wealth (as defined by in the Covenant on Civil and Political Rights, UN, 16/1211966), The "sins" committed in the past by the US, as they were or are the destruction of forests and indigenous peoples and atmospheric pollution, do not constrain or inhibit them. Finally, they tend to divide the world into two blocks separated by the gap in development, resulting in disturbing tensions and conflicts in the name of the good World Order.

description: A composite material comprising randomly distributed spherical particles of two different isotropic dielectric-magnetic materials is homogenized using the second-order strong-property-fluctuation theory in the long-wavelength approximation. Whereas neither of the two constituent materials by itself supports planewave propagation with negative phase velocity (NPV), the homogenized composite material (HCM) can. The propensity of the HCM to support NPV propagation is sensitive to the distributional statistics of the constituent material particles, as characterized by a two--point covariance function and its associated correlation length. The scope for NPV propagation diminishes as the correlation length increases.

description: The Schrödinger equation for an electron in a mesoscopic ring, in the presence of the Rashba and linear Dresselhaus terms of the spin-orbit interaction (SOI) and of a magnetic field $B$, is solved exactly. The effective electric fields of these terms as well as $B$ have perpendicular and radial components. The interplay between them and $B$ and their influence on the spectrum is studied. The transmission through such a ring, with two leads connected to it, is evaluated as a function of the SOI strengths and of the orientations of these fields. The Rashba and Dresselhaus terms affect the transmission in different ways. The transmission through a series of rings with different radii and with SOI in both arms of the rings or only in one of them is also evaluated. For weak magnetic fields $B\leq 1$ T the influence of the Zeeman term on the transmission, assessed by perturbation theory, is negligible.

description: User participation is considered an effective way to conduct requirements engineering, but user-developer perception gaps in requirements understanding occur frequently. Since user participation in practice is not as active as we expect and the requirements perception gap has been recognized as a risk that negatively affects projects, exploring whether user-developer perception gaps in requirements understanding will hinder user participation is worthwhile. This will help develop a greater comprehension of the intertwined relationship between user participation and perception gap, a topic that has not yet been extensively examined. This study investigates the direct and mediating influences of user-developer requirements perception gaps on user participation by integrating requirements uncertainty and top management support. Survey data collected from 140 subjects were examined and analyzed using structural equation modeling. The results indicate that perception gaps have a direct negative effect on user participation and negate completely the positive effect of top management support on user participation. Additionally, perception gaps do not have a mediating effect between requirements uncertainty and user participation because requirements uncertainty does not significantly and directly affect user participation, but requirements uncertainty indirectly influences user participation due to its significant direct effect on perception gaps. The theoretical and practical implications are discussed, and limitations and possible future research areas are identified.

description: The essence of shear instability is fully revealed both mathematically and physically. A general sufficient and necessary stable criterion is obtained analytically within linear context. It is the analogue of Kelvin-Arnol'd theorem, i.e., the stable flow minimizes the kinetic energy associated with vorticity. Then the mechanism of shear instability is explored by combining the mechanisms of both Kelvin-Helmholtz instability (K-H instability) and resonance of waves. It requires both concentrated vortex and resonant waves for the instability. The waves, which have same phase speed with the concentrated vortex, have interactions with the vortex to trigger the instability. We call this mechanism as "concentrated vortex instability". The physical explanation of shear instability is also sketched. Finally, some useful criteria are derived from the theorem. These results would intrigue future works to investigate the other hydrodynamic instabilities.

description: Acoustic metasurfaces manipulate waves with specially designed structures and achieve properties that natural materials cannot offer. Similar surfaces work in audio frequency range as well and lead to marvelous acoustic phenomena that can be perceived by human ears. Being intrigued by the famous Maoshan Bugle phenomenon, we investigate large scale metasurfaces consisting of periodic steps of sizes comparable to the wavelength of audio frequency in both time and space domains. We propose a theoretical method to calculate the scattered sound field and find that periodic corrugated surfaces work as spatial filters and the frequency selective character can only be observed at the same side as the incident wave. Maoshan Bugle phenomenon can be well explained with the method. Finally, we demonstrate that the proposed method can be used to design acoustical landscapes, which transform impulsive sound into famous trumpet solos or other melodious sound.
Ontology of Entrepreneurship

description: Fifteen renditions of the Entrepreneur located in within six ‘eras’ are found via a broad review of Entrepreneurship ontological literature. A Critical Realist analytical approach reveals that these renditions and eras correspond to an evolution of the entrepreneurial behaviour within evolving social settings in Europe from the late 1600’s until the present. It is proposed that the Weberian disenchantment of Europe beginning in the far west and moving east over a period of three centuries created an existential social tension that fractured the psyche of those habituated to the static Feudal Order. A feedback loop emerges that drives ever increasing uncertainty that destabilises not only Europe, but the sense of control felt by individuals. Those who lived outside the Feudal Order who traditionally were subject to uncertainty are recognised as the entrepreneur in the literature. These outcasts and outsiders have superior personal control and agency are placed to manage and exploit uncertainty which they see as opportunity. Biosciences regarding personal agency, control, psychological limiters and developmental psychology offer tangential support for the proposition that there really is an entrepreneurial personality. Two further aspects are considered. The first is the, to date, barely examined source of insight that is the ‘Aha! Moment’. The second is that of the ‘ecosystem’ which, though a useful heuristic, is found to be theoretically indeterminate. An alternative is proposed via the adoption of Urie Bronfenbrenner’s Bio-Ecological Model along with a process model reflecting the conditions revealed for entrepreneurship

description: We discuss the current developments by the European Twisted Mass Collaboration in extracting parton distribution functions from the quasi-PDF approach. We concentrate on the non-perturbative renormalization prescription recently developed by us, using the RI$'$ scheme. We show results for the renormalization functions of matrix elements needed for the computation of quasi-PDFs, including the conversion to the $\overline{\rm MS}$ scheme, and for renormalized matrix elements. We discuss the systematic effects present in the $Z$-factors and the possible ways of addressing them in the future.

Terremoto e ricostruzione strategica: il complesso di Villa la Quiete e la Casa del Giardiniere a Treia / Earthquake and strategic reconstruction: the complex of Villa la Quiete and the Gardener's House in Treia (Mc)

description: Il complesso di Villa la Quiete viene realizzato a Treia dal gonfaloniere Luigi Angelini che, nel 1815, commissiona all’architetto Giuseppe Valadier il progetto di un “Casino di campagna”. L’edificio principale viene realizzato attorno al 1820, all’interno di un grande parco di circa 4 ettari, ricco di vegetazione secolare successivamente arricchito con costruzioni accessorie (tempietti, rotonde, terrazzamenti e sottopassi). Il fabbricato adibito a Casa del Giardiniere costituisce, assieme a quattro propilei, l’ingresso monumentale a questo grande ed articolato sistema. Il terremoto che ha colpito l’Italia centrale nel 2016 ha fortemente danneggiato le strutture edificate ed il comune di Treia, che ne detiene la proprietà, ha intrapreso un percorso progettuale per il restauro, il riuso ed il miglioramento antisismico degli edifici presenti, al fine di restituire alla fruizione pubblica questo importante complesso monumentale. Il progetto per il restauro della “casa del giardiniere” è il primo tassello di questo più ampio programma. The “Villa La Quiete” complex was built in Treia by the gonfalonier Luigi Angelini who, in 1815, entrusts the project of a “Country Casino” to the architect Giuseppe Valadier. The main building was built around 1820, inside a large park of about 4 hectares, rich in ancient vegetation; later the accessory constructions were built (small temples, pedestrian routes, terracing and underpasses). The building named the Gardener’s House, together with the four propylaea, constitutes the monumental entrance to this large and complex system. The earthquake that struck central Italy, in 2016, severely damaged the built structures and the municipality of Treia, which owns the property, has started a project for the restoration, reuse and anti-seismic improvement of the buildings, to return this important monumental complex to public use. The project for the restoration of the “Gardener’s House” is the first step of this broader program.

description: Measurements and theoretical calculations of meson form factors are essential for our understanding of internal hadron structure and QCD, the dynamics that bind the quarks in hadrons. The pion electromagnetic form factor has been measured at small space-like momentum transfer $|q^2| < 0.3$~GeV$^2$ by pion scattering from atomic electrons and at values up to $2.5$~GeV$^2$ by scattering electrons from the pion cloud around a proton. On the other hand, in the limit of very large (or infinite) $Q^2=-q^2$, perturbation theory is applicable. This leaves a gap in the intermediate $Q^2$ where the form factors are not known. As a part of their 12 GeV upgrade Jefferson Lab will measure pion and kaon form factors in this intermediate region, up to $Q^2$ of $6$~GeV$^2$. This is then an ideal opportunity for lattice QCD to make an accurate prediction ahead of the experimental results. Lattice QCD provides a from-first-principles approach to calculate form factors, and the challenge here is to control the statistical and systematic uncertainties as errors grow when going to higher $Q^2$ values. Here we report on a calculation that tests the method using an $η_s$ meson, a 'heavy pion' made of strange quarks, and also present preliminary results for kaon and pion form factors. We use the $n_f=2+1+1$ ensembles made by the MILC collaboration and Highly Improved Staggered Quarks, which allows us to obtain high statistics. The HISQ action is also designed to have small discretisation errors. Using several light quark masses and lattice spacings allows us to control the chiral and continuum extrapolation and keep systematic errors in check.
