subject: animal food origin

description: This paper attempts to identify the perception of the quality of food of animal origin by Polish consumers and their opinion on higher quality with particular emphasis on the chosen methods of production and processing referring to the protection of the environment and animal welfare. In 2013 a quantitative study of the project: “BIOFOOD – innovative, functional products of animal origin” was conducted. Analysis of the results can be noted that the surveyed respondents declared a relatively high level of compliance with the statement that the high quality food of animal origin is produced in an environmentally friendly manner, taking into account the rights of farm animals and using the organic production. At the same time there was a relatively high level of acceptance in relation to the method for increasing the quality of food of animal origin ie. the use of production, including animal husbandry that respects the rights of farm animals
A Simple System For Coleman-De Luccia Transitions

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: This paper presents a simple framework that organizes thin-wall Coleman-De Luccia instantons based on the Euclidean geometries of their original and tunneled vacuum patches. We consider all a priori allowed vacuum pairs (de Sitter or Anti-de Sitter for either patch, Minkowski can be obtained as a limit of either), and $O(4)$-symmetric thin-wall geometries connecting them. For each candidate bounce geometry, either a condition under which a solution to the $O(4)$-invariant equations of motion exists is derived, or the would-be vacuum transition is ruled out. For the parameter regimes in which a solution exists, we determine whether expansion/contraction of the bounce supplies a negative mode in the second variation of the Euclidean action. All results follow from the monotonicity of a single function.

description: The recent Comment by Vorontsov [arXiv:2007.13696] claims that surface pair-density-wave superconductivity with critical temperature higher than the bulk FFLO critical temperature is not supported by microscopic theory. The conclusion is reached by using an approximate semi-microscopic quasiclassical approach. Here we show that a fully microscopic approach unambiguously demonstrates the existence of surface pair-density-wave superconductivity.

title: Ofsted 2005 : a new relationship with primary headteachers?
Creators: name: Watts, Yvonne Joy
Publisher: name: The Open University
Year: 2012

description: This study concerns the role of the English primary school headteacher within the school inspection process, specifically after the implementation of the key changes made by Ofsted to their inspection framework in 2005. These amendments were considerable, and included moving to shorter inspections with less notice given, alongside schools being required to undertake self- evaluation to inform the inspectorate. Much of a primary school's self-evaluation falls to the headteacher and the study focuses on the implications of Ofsted's New Relationship with Schools for the head. Mixed methods are used for the study. A questionnaire survey was sent to all 749 primary headteachers whose schools were inspected in November 2006 and follow-up interviews were undertaken with a sample of these. The extent of a head's autonomy is considered, to investigate whether variations in approach make any difference to the outcomes for a school. This practitioner study is undertaken by a serving primary headteacher which helps inform the research focus and data analysis. It includes some personal reflection from the researcher, including a consideration of the implications of the research on her professional role. The findings indicate that the primary headteachers in the study believe the new inspection process to have both advantages and disadvantages. Although there is some criticism of Ofsted, most heads recognise the need to be accountable, even though multiple accountabilities to a variety of stakeholders weigh heavily for some. The study concludes that the respondent heads who approach the inspection process with confidence and belief in their school and its practices may help to support a positive outcome by ensuring the school will be seen in the best light possible. This finding may be of interest to primary head teachers and could help to inform their professional practice.

description: The paper presents an explanation of the essence of creation of consumer communities that have been developing for several years on the marketing market. A hypothesis was made that says that the mechanism of interdependence existing in the consumer community can be used to create sustainable consumption on the market. The method of literature study was used in the article. In the introduction it was proved that regardless of whether a community is formed independently around the brand or not, its existence is initiated by a company and its members interact by providing one another with the patterns of consumption. The reasons for consumers’ belonging to communities around the brand were described. The presented literature analysis revealed that the appropriate management of the community around the brand can serve the company to create a sustainable product consumption.

description: Motivated by the recent discovery of superconductivity in the infinite-layer (Sr,Nd)NiO$_2$ films with Sr content $x \simeq0.2$ [Li et al., Nature (London) \textbf{572}, 624 (2019)], we examine the effects of electron correlations and Sr-doping on the electronic structure, Fermi surface topology, and magnetic correlations in (Nd,Sr)NiO$_2$ using a combination of dynamical mean-field theory of correlated electrons and band-structure methods. Our results reveal a remarkable orbital selective renormalization of the Ni $3d$ bands, with $m$*/$m\sim 3$ and 1.3 for the $d_{x^2-y^2}$ and $d_{3z^2-r^2}$ orbitals, respectively, that suggests orbital-dependent localization of the Ni $3d$ states. We find that upon hole doping (Nd,Sr)NiO$_2$ undergoes a Lifshitz transition of the Fermi surface which is accompanied by a change of magnetic correlations from the three-dimensional (3D) Néel $G$-type (111) to the quasi-2D $C$-type (110). We show that magnetic interactions in (Nd,Sr)NiO$_2$ demonstrate an unanticipated frustration, which suppresses magnetic order, implying the importance of in-plane spin fluctuations to explain its superconductivity. Our results suggest that frustration is maximal for Sr-doping $x \simeq 0.1$--0.2, which is in agreement with an experimentally observed doping value Sr $x \simeq 0.2$ of superconducting (Nd,Sr)NiO$_2$.

description: The most important stakeholder of any organization is the consumer. Today’s consumers are socially and ecologically aware and are increasingly guided by ethical criteria. Pro-social activity of companies, changes in management, informing the client, reliable messages about the benefi ts of consumption of the offered products increase the fi rm’s competitiveness on the market, as well as its impact on economic effi ciency. The aim of this article is to show whether and what principles of corporate social responsibility in the area of relationships with consumers are usually taken into account in the activities of enterprises. We analysed companies of the SME sector, agribusiness from Mazowieckie – own research carried out in 2011. And nationwide sample companies examined by PARP in 2011. To compare the analysis of CSR activities in the area of relationships with consumers regarding large companies, good practices are included in reports FOB 2011–2013. The analysis shows that socially responsible market practices in the area of relationships with consumers lead to building a sustainable competitive advantage based on trust.

title: Dialogue-with-self : reflective learning for the professional development of postgraduate pharmacists
Creators: name: Black, Patricia Elizabeth
Publisher: name: The Open University
Year: 2006

description: The aim of this study was to explore learning, and dialogue-with-self in facilitating reflection on learning and professional practice, with postgraduate pharmacists.

 The study was set in the context of a Prescribing Course for pharmacists where the participants were exposed to a systematic reflective learning approach that was new to them as learners, and which was facilitated by a structured written Reflective Portfolio.

 Data were generated from a phenomenological study that included focus groups and individual interviews as the methods of enquiry. The inductive approach to data collection and analysis generated a Model of Reflection that has not previously been described that illustrates the complexities of reflective learning. The study therefore challenges the simplicity with which 'reflection' has generally been portrayed in the literature, and indicates why students and practitioners may experience difficulties with it. It is proposed that the research provides a significant contribution to the understanding of reflection for learning and professional practice development since this Model of Reflection is arguably transferable or relatable to other health professions and other disciplines.

 This study has confirmed that postgraduate pharmacy students perceive learning in ways that are compatible with existing published literature, particularly that relating to deep and surface approaches to learning, and that they perceive reflective learning to be analogous with a deep learning approach.

 The study challenges the notion expressed in the literature that reflective dialogue-with-others through face-to-face interaction is essential for learners to develop their skill in reflection and applying it to professional practice. The study has shown that reflection for learning and practice is achievable by pharmacists principally through dialogue-with-self using the medium of a structured written portfolio that facilitates systematic reflection.

 The study has also raised questions about the Royal Pharmaceutical Society's model for continuing professional development (CPD), and provides some insight into the apparent mistrust that pharmacists have of it and their professional body. Therefore, this research also has implications for the Pharmacy regulator's policy and recommended practice regarding CPD.

description: We examine whether the LHCb vector $ud\bar{c}\bar{s}$ state $X(2900)$ can be interpreted as a kinematical cusp effect arising from $\bar D^*K^*$ and $\bar D_1 K^*$ interactions. The production amplitude is modelled as a triangle diagram with hadronic final state interactions. A satisfactory fit to the Dalitz plot projection is obtained that leverages the singularities of the production diagram without the need for $\bar{D}K$ resonances. A somewhat better fit is obtained if the final state interactions are strong enough to generate resonances, although the evidence in favour of this scenario is not conclusive.

description: AbstractIn pursuit of reducing the dead-weight of precast concrete structures, one approach is by adopting lightweight concrete. EN 13369:2013 specifies a minimum cube compressive strength of at least 18 MPa for the lightweight concrete to be eligible for use in reinforced precast concrete products. This study conducts an experiment using LECA and EPA to produce lightweight concrete for structural use. Density, concrete quality, and strength of various mixes are observed by conducting cube compressive test and UPV test. Two phases of experiments were conducted, where the first phase variable is the percentage of LECA replacing the normal coarse aggregate, while the second phase variable is the percentage of EPA replacing the sand proportion. The optimum concrete mix is found to be the mix with 60% LECA and 50% EPA replacements, which achieved D1.8 lightweight density category that surpasses the specified minimum cube compressive strength and falls under the good quality concrete type according to the UPV rating. In summary, the inclusion of LECA and EPA into the concrete mix will decrease the cube compressive strength, lower the density, escalate the slump value and the travelling time of the ultrasonic pulse, but at the same time able to produce lightweight structural concrete

description: This study investigates the pairwise shock transmission and volatility spillover of Ethereum with Ripple, Stellar and Monero. The BEKK model has been deployed between 8 August 2015 and 30 September 2019. The results indicate a significant shock transmission from Ethereum to Ripple and Monero, but not on Stellar. On the other hand, shock transmission is only found from Ripple to Ethereum. Bi-directional volatility spillover was identified between Ethereum and both Ripple and Stellar. Uni-directional volatility spillover was present from Ethereum to Monero but not vice versa

description: We present phase-resolved optical spectroscopy of the eclipsing nova-like cataclysmic variable EC21178-5417 obtained between 2002 and 2013. The average spectrum of EC21178-5417 shows broad double-peaked emission lines from HeII 4686 Å (strongest feature) and the Balmer series. The high-excitation feature, CIII/NIII at 4640-4650 Å, is also present and appears broad in emission. A number of other lines, mostly HeI, are clearly present in absorption and/or emission. The average spectrum of EC21178-5417 taken at different months and years shows variability in spectral features, especially in the Balmer lines beyond H$γ$, from pure line emission, mixed line absorption and emission to pure absorption lines. Doppler maps of the HeII 4686 Å emission reveal the presence of a highly-inclined asymmetric accretion disc and a two spiral arm-like structure, whereas that of the Balmer lines (H$α$ and H$β$) reveal a more circular accretion disc. There is no evidence of a bright spot in the Doppler maps of EC21178-5417 and no emission from the secondary star is seen in the tomograms of the HeII 4686 Å and Balmer lines. Generally, the emission in EC21178-5417 is dominated by emission from the accretion disc. We conclude that EC21178-5417 is a member of the RW Tri or UX UMa sub-type of nova-like variables based on these results and because it shows different spectral characteristics at different dates. This spectral behaviour suggests that EC21178-5417 undergoes distinct variations in mass transfer rate on the observed time scales of months and years.

description: Research has demonstrated that the use of weather index insurance is one of the most effective ways of cushioning smallholders against the vagaries of nature like excess rains and drought hence improving smallholders’ food insecurity status. We use cross sectional data from 401 farm households in Embu County, eastern Kenya and a propensity score matching technique. We model the effects of adoption of weather index based insurance decision on food security of the smallholder farmers. We find that a positive impact on food security is associated with the uptake of index insurance. This suggests that index insurance technology can benefit farmers more through up-scaled use of index based insurance in the context of their socio-economic conditions and institutional arrangements.

description: The article presents sources and a scope of professional information which was researched by Polish and British village citizens as well as a comparative analysis of the preferences of both groups in the study area. The empirical research was conducted in November and December 2015 among 147 farmers and agriculture-related living in Poland and among 76 farmers and agriculture-related living in the UK. The results of the comparative analysis show that the source of expert information for both groups were mostly websites of the manufacturers and distributors of agricultural inputs (almost ¾ of responses) and agricultural magazines (over ⅔ responses). In order to solve professional problems Poles more often than the Brits used the social media as well as used state consultants, but the British used private advisory services more frequently than the Polish. In both countries, respondents were interested in a variety of information on agriculture and environment. However, British respondents paid more attention to the innovation aspect of agriculture than Polish citizens from the countryside, while the Poles were more interested in the agricultural production than those polled in the UK.

description: Reported in this paper is the impact of the fluctuations of the geometry of the nano-meter gas containers in the medium on the NMR line shape of the gas inside of the nano-containers. We calculate exactly the NMR line shape of the gas of spin-1/2 carrying molecules for two typical dynamics of the nano-container volume and the orientation with respect to the external magnetic field: (i) for a Gaussian stochastic dynamics, and (ii) for the regular harmonic vibrations. For the Gaussian ensemble of static disordered containers having an infinite correlation time, $τ_{\sf c} \to \infty $, the overall line shape is shown to obey a logarithmic low frequency asymptotics, $ I(ω) = {const} \times \ln (\frac{1}ω)$, at $ω\to 0$, and exponentially decaying asymptotics in a high frequency domain. For the Gaussian ensemble of the rapidly fluctuating containers of a finite $τ_{\sf c}$, the overall line shape has a bell-shaped profile with $\sim ω^{-4}$ far wing behaviour. In addition, we calculate exactly a satellite structure of the NMR line shape when the nano-bubbles in a liquid are affected by the harmonic deformations due to the acoustic waves.

description: We analyse the distribution and origin of OVI in the Circumgalactic Medium (CGM) of dark-matter haloes of $\sim 10^{12}$ M$_\odot$ at $z\sim1$ in the VELA cosmological zoom-in simulations. We find that the OVI in the inflowing cold streams is primarily photoionized, while in the bulk volume it is primarily collisionally ionized. The photoionized component dominates the observed column density at large impact parameters ($\gtrsim 0.3 R_{\rm vir}$), while the collisionally ionized component dominates closer in. We find that most of the collisional OVI, by mass, resides in the relatively thin boundaries of the photoionized streams. We discuss how the results are in agreement with analytic predictions of stream and boundary properties, and their compatibility with observations. This allows us to predict the profiles of OVI and other ions in future CGM observations and provides a toy model for interpreting them.

Recombinant expression and functional characterization of human hephaestin : a multicopper oxidase with ferroxidase activity
Creators: name: Griffiths, Tanya A. M.
Publisher: name: University of British Columbia
Year: 2010

description: Human hephaestin is a transmembrane protein that has been implicated in duodenal iron export. Mutations in the murine hephaestin gene produce microcytic, hypochromic anemia that is refractory to oral iron therapy. Hephaestin shares -50% sequence identity with the plasma multicopper ferroxidase ceruloplasmin including conservation of residues involved in disulfide bond formation and metal coordination. Based on this similarity to ceruloplasmin, human hephaestin may also bind copper and possess ferroxidase activity. To test this hypothesis, human hephaestin cDNA has been cloned by reverse transcription of human duodenal mRNA. Following in vitro mutagenesis to engineer the encoded polypeptide so that it was suitable for expression and purification, the cDNA was cloned into the expression vector pNUT and introduced into baby hamster kidney cells. After selection with methotrexate, the baby hamster kidney cells secreted the recombinant human hephaestin into the medium at a level of -2 mg/L. Purification was achieved by a single immunoaffinity chromatography step. As judged by SDS-PAGE, N-terminal sequence analysis, and matrix assisted laser desorption ionization time-of-flight mass spectrometry, the purified hephaestin was homogeneous with a mass of 129,600 Da suggesting a carbohydrate content of -7.7%. Inductively coupled plasma mass spectrometry revealed that recombinant hephaestin contained an average of 3.13 atoms of copper per protein molecule. A visible absorption maximum was observed at 607 nm that is consistent with the presence of a Type 1 copper site. By using ferrous ammonium sulfate as a substrate, recombinant hephaestin was shown to have ferroxidase activity with a Km of 2.1 fiM for Fe(II). Lastly, urea PAGE showed that hephaestin was able to oxidize Fe(II) to Fe(III) that was acceptable by apo transferrin to form diferric transferrin.

description: Human capital is an important factor in the economic growth of the country, therefore it should be developed and supported. One of the components of human capital is health, which can improve through physical activity. This is especially important for young people who are just shaping their habits.The aim of the article was to examine the preferences of young people in Warsaw in terms of physical activity as a form of leisure activity. It is encouraging that among the respondents there was neither the one person who did not practice any sport. Nearly 37 % of the respondents declared that they take physical activity 1–2 times a week, and 29 % even 3–4 times a week, which should be assessed very positively. The main motive of physical activity among people surveyed were health reasons. Young people of Warsaw are aware of good consequences and willing to take physical activity. Especially popular among them is running and dancing, which certainly is associated with the current fashion.

By imposing a four-fold symmetry and employing $Gaia$ proper motions, we are able to infer the behaviour of the velocity ellipsoid between $\approx3$ and $\approx30$ kpc from the centre of the Galaxy. We detect the presence of two distinct components: a dominant non-rotating halo-like population and a much smaller rotating disc-like population. We demonstrate that the halo RR Lyrae can be described as a superposition of an isotropic and radially-biased parts. The radially-biased portion of the halo is characterised by a high orbital anisotropy $β\approx0.9$ and contributes between 50\% and 80\% of the halo RR Lyrae at $5

description: Given a non-empty closed convex subset $\mathsf{F}$ of density matrices, we formulate conditions that guarantee the existence of an $\mathsf{F}$-morphism (namely, a completely positive trace-preserving linear map that maps $\mathsf{F}$ into itself) between two arbitrarily chosen density matrices. While we allow errors in the transition, the corresponding map is required to be an exact $\mathsf{F}$-morphism. Our findings, though purely geometrical, are formulated in a resource-theoretic language and provide a common framework that comprises various resource theories, including the resource theories of bipartite and multipartite entanglement, coherence, athermality, and asymmetric distinguishability. We show how, when specialized to some situations of physical interest, our general results are able to unify and extend previous analyses. We also study conditions for the existence of maximally resourceful states, defined here as density matrices from which any other one can be obtained by means of a suitable $\mathsf{F}$-morphism. Moreover, we quantitatively characterize the paradigmatic tasks of optimal resource dilution and distillation, as special transitions in which one of the two endpoints is maximally resourceful.

description: This paper examines a new parallel computation model called bulk synchronous farm (BSF) that focuses on estimating the scalability of compute-intensive iterative algorithms aimed at cluster computing systems. In the BSF model, a computer is a set of processor nodes connected by a network and organized according to the master/slave paradigm. A cost metric of the BSF model is presented. This cost metric requires the algorithm to be represented in the form of operations on lists. This allows us to derive an equation that predicts the scalability boundary of a parallel program: the maximum number of processor nodes after which the speedup begins to decrease. The paper includes several examples of applying the BSF model to designing and analyzing parallel nu-merical algorithms. The large-scale computational experiments conducted on a cluster computing system confirm the adequacy of the analytical estimations obtained using the BSF model.

description: An analysis of institutional data to understand the outcome of the many obstacles faced by students from historically disadvantaged backgrounds is important in order to work towards promoting equity and inclusion for all students. We use 10 years of institutional data at a large public research university to investigate the grades earned (both overall and in STEM courses only) by students categorized on four demographic characteristics: gender, race/ethnicity, low-income status, and first-generation college student status. We find that on average across all years of study and for all clusters of majors, underrepresented minority students experience a larger penalty to their mean overall and STEM GPA than even the most disadvantaged non-URM students. Moreover, the underrepresented minority students with additional disadvantages due to socioeconomic status or parental education level were even further penalized in their average GPA. Furthermore, we also find that while women in all demographic groups had a higher average overall GPA, these gender differences are almost completely non-existent in STEM GPA except among the most privileged students. These findings suggest that there is need to provide support to bridge the gaps that emanate from historical disadvantages to certain groups.

description: The movement toward bio-economy means the complex system changes, it concerns such wide and important aspects as food security, resource efficiency, biodiversity, job creation, GDP production. Purpose of the article – generalizing of the basic parameters of food security and outlining of the impact directions of the bio-economy. There are analyzed the meaning of food security in the article, described the links between food security and the bioeconomy, determined that the bioeconomy has the potential to improve food security through the development of more efficient systems of agricultural production which can significantly increase the production of food by increasing the sustainability of the agricultural sector, which is essential in the long term. We consider that there is some scope for the development of the bioeconomy in Ukraine, including the sector of biofuels production and «green» sector without endangering food security. Dilemmas «food or fuel» for Ukraine is not acute at this stage, however, the benefits from the bioeconomy transition are quite significant.
On the Boundary Ergodic Problem for Fully Nonlinear Equations in Bounded Domains with General Nonlinear Neumann Boundary Conditions

description: We study nonlinear Neumann type boundary value problems related to ergodic phenomenas. The particularity of these problems is that the ergodic constant appears in the (possibly nonlinear) Neumann boundary conditions. We provide, for bounded domains, several results on the existence, uniqueness and properties of this ergodic constant.
On the early evolution of massive star clusters: the case of cloud D1 and its embedded cluster in NGC 5253

description: We discuss a theoretical model for the early evolution of massive star clusters and confront it with the ALMA, radio and infrared observations of the young stellar cluster highly obscured by the molecular cloud D1 in the nearby dwarf spheroidal galaxy NGC 5253. We show that a large turbulent pressure in the central zones of D1 cluster may cause individual wind-blown bubbles to reach pressure confinement before encountering their neighbors. In this case stellar winds are added to the hot shocked wind pockets of gas around individual massive stars that leads them to meet and produce a cluster wind in time-scales less than $10^5$ yrs. In order to inhibit the possibility of cloud dispersal, or the early negative star formation feedback, one should account for mass loading that may come, for example, from pre-main sequence (PMS) low-mass stars through photo-evaporation of their proto-stellar disks. Mass loading at a rate in excess of 8$\times 10^{-9}$ M$_{\odot}$ yr$^{-1}$ per each PMS star is required to extend the hidden star cluster phase in this particular cluster. In this regime, the parental cloud remains relatively unperturbed, while pockets of molecular, photoionized and hot gas coexist within the star forming region. Nevertheless, the most likely scenario for cloud D1 and its embedded cluster is that the hot shocked winds around individual massive stars should merge at an age of a few millions of years when the PMS star proto-stellar disks vanish and mass loading ceases that allows a cluster to form a global wind.

title: Flat space cosmology and phase transitions in four dimensions
Creators: name: Breunhölder, Veronika
Publisher: name: TU Wien
Year: 2015
Subjects: subject: Flat space holography
subject: Phase transitions

description: We generalize a phase transition between three-dimensional hot flat space and a cer- tain type of flat space cosmology to four dimensions. To do so, an analogue of this cosmology is constructed in four dimensions and novel flat space boundary conditions are established, that differ from the usual boundary conditions of asymptotically flat space in four dimensions. Also we construct the Lie algebra of asymptotic Killing vectors that preserve these boundary conditions. A generalization of the phase transition can then be found straightforwardly. We will find that there are some differences in possible interpretations as compared to the three-dimensional version, which will also be discussed.

description: Euclidean quantum gravity is reconsidered, in the conformal mode approximation. Applying techniques from glass theory, we argue that the Euclidean partition function hides metastable states, which can be counted. This may reconcile conflicting results on the uniqueness of the de Sitter vacuum, and may be relevant to the cosmological constant problem.

description: This case study identified the subjective change in a patient diagnosed with Borderline Personality Disorder (BPD) by analyzing the dynamic patterns that emerged during discursive interaction with her therapist during a successful long-term psychotherapy. A qualitative analysis was conducted by applying the Model of Analysis of Discursive Positioning in Psychotherapy (MAPP), tracking voices and the personal positions of the patient and therapist in all sessions. Subsequently, dynamic patterns were identified and the hypothetical attractors were defined (i.e., the most stable patterns in the interaction of voices) using the Space State Grid (SSG) technique. Five sessions (representing the initial, middle and final stages) were selected to describe the trajectory of the patient’s subjective change. These sessions highlight the presence of different attractors and depict the intersubjective interaction that developed during the process. The results suggest a process of subjective transformation from a monological to a dialogical dimension, a change supported by therapeutic interaction based on propositional and reflective discursive aspects; a transition from a state of dissociation of the patient to a reorganization of her subjectivity. The most relevant characteristics of this process as an emergent quality of psychotherapy and its relation to the patient’s positive outcomes are discussed.

description: Landau damping is an essential mechanism for ensuring collective beam stability in particle accelerators. Precise knowledge of how strong Landau damping is, is key to making accurate predictions on beam stability for state-of-the-art high energy colliders. In this paper we demonstrate an experimental procedure that would allow quantifying the strength of Landau damping and the limits of beam stability using an active transverse feedback as a controllable source of beam coupling impedance. In a proof-of-principle test performed at the Large Hadron Collider stability diagrams for a range of Landau Octupole strengths have been measured. In the future, the procedure could become an accurate way of measuring stability diagrams throughout the machine cycle.
