description: Through my practice-led research, The Archive of Gestures, I unearth gestures and alternative narratives left out of the Israeli accounts of the occupation in Palestine, dealing with the body as a form and source of archive. I do this by re-enacting, analysing, and commenting on these gestures and the contexts in which they were produced. Most importantly, I develop processes that allow me to engage with the bodies of the audience members through participatory choreographic work. In this way, I aim to disseminate the bodily archives I generate, making them accessible to others, and reflecting on who can create, own, and access archives in the Palestinian colonial context. My research, which I consider a form of a decolonial gesture, collects and revives fragments of a gestural collective narrative in confrontation with the structural erasures of the colonial situation. In my thesis I engage with different theories—from archive reappropriation as decolonial practice, to the body as a valuable site of the archive, to audience participation theories on creating afterlives of the event and facilitating the emergence of new decolonial subjectivities. I also analyse relevant artisitc works from Palestine and around the world that deal with decolonial archives, the body as a source of archive, and audience participation as a form of creating shared experience. My gestural archive retrieves stories related to my own biography as a refugee in the Palestinian diaspora, later as an occupied subject in Palestine, and now as citizen of the world living in the United Kingdom. Methodologically, I construct my bodily archive by engaging with informal archival material (videos, pictures, written documents), oral histories, and imagination. I explore using these different forms of physical archives in tandem with the bodily archives in order to investigate techniques to unearth, as well as revive and disseminate, the movements and gestures in the archived narratives. I also combine theory and practice to discover forms of constructing and transmitting a living archive of gestures as a contribution to the production of new knowledge.

description: The nonlinear instability of anti-de Sitter spacetime has recently been established with the striking result that generic initial data collapses to form black holes. This outcome suggests that confined matter generically collapses, and that collapse can only be halted -- at most -- by nonlinear bound states. Here we provide evidence that such mechanism can operate even in asymptotically flat spacetimes, by studying the evolution of the Einstein-Klein-Gordon system for a self-interacting scalar field. We show that (i) configurations which do not collapse promptly can do so after successive reflections off the potential barrier, but (ii) that at intermediate amplitudes and Compton wavelengths, collapse to black holes is replaced by the appearance of oscillating soliton stars. Finally, (iii) for very small initial amplitudes, the field disperses away in a manner consistent with power-law tails of massive fields. Minkowski is stable against gravitational collapse. Our results provide one further piece to the rich phenomenology of gravitational collapse and show the important interplay between bound states, blueshift, dissipation and confinement effects.

description: The lack of evidence for superparticles at the CERN LHC, along with the rather high value of the Higgs mass, has sharpened the perception that supersymmetric model parameter space is highly electroweak fine-tuned (EWFT). We compare three measures of fine-tuning in SUSY models. 1. \Del_HS measures a terms containing large log contributions to m_Z that are inevitable in models defined at scales much higher than the electroweak scale. 2. \Del_BG measures variation in m_Z against variation of model parameters and allows for correlations among high scale parameters which are not included in \Del_HS. 3. The model-independent \Del_EW measures how naturally a model can generate the measured value of m_Z=91.2 GeV in terms of weak scale parameters alone. We hypothesize an overarching Ultimate Theory (UTH) wherein the high scale soft terms are all correlated. The UTH might be contained within the more general effective SUSY theories popular in the literature. For \Del_HS, EWFT can be overestimated by neglecting additional non-independent terms which lead to large cancellations. For \Del_BG, EWFT can be overestimated by applying the measure to the effective theories instead of to the UTH. The measure \Del_EW allows for the possibility of parameter correlations which should be present in the UTH and, since it is model-independent, provides the same value of EWFT for the effective theories as should occur for the UTH. We find that the well-known mSUGRA/CMSSM model is fine-tuned under all three measures so that it is unlikely to contain the UTH. The non-universal Higgs model NUHM2 appears fine-tuned with \Del_HS,BG > 10^3. But since \Del_EW can be as small as 7 (corresponding to 14% fine-tuning), it may contain the UTH for parameter ranges which allow for low true EWFT.

description: Self-consistent transport simulation of ITER scenarios is a very important tool for the exploration of the operational space and for scenario optimisation. It also provides an assessment of the compatibility of developed scenarios (which include fast transient events) with machine constraints, in particular with the poloidal field (PF) coil system, heating and current drive (H&CD), fuelling and particle and energy exhaust systems. This paper discusses results of predictive modelling of all reference ITER scenarios and variants using two suite of linked transport and equilibrium codes. The first suite consisting of the 1.5D core/2D SOL code JINTRAC [1] and the free boundary equilibrium evolution code CREATE-NL [2,3], was mainly used to simulate the inductive D-T reference Scenario-2 with fusion gain Q=10 and its variants in H, D and He (including ITER scenarios with reduced current and toroidal field). The second suite of codes was used mainly for the modelling of hybrid and steady state ITER scenarios. It combines the 1.5D core transport code CRONOS [4] and the free boundary equilibrium evolution code DINA-CH [5].

description: Pharmaceuticals are a new class of water contaminants that need to be effectively removed. This study combines GO@Fe3O4 with CeO2 nanoparticles via a simple procedure known as heterogeneous visible-light-driven photocatalyst. The photocatalytic potential of the GO@Fe3O4@CeO2 was examined via photodegradation of tamoxifen (TMX) and doxorubicin (DOX) under visible-light excitation. The crystallinity and morphology of the synthesized photocatalyst was characterized utilizing SEM, EDS, XRD, FTIR, VSM, and UV–vis. The UV–Vis analyses provided the bandgap value of 3.17 eV for GO@Fe3O4@CeO2. Then, the influence of some key factors such as pH (3–10), photocatalyst dose (0.006-0.04 g), and time (0-120) were studied. The findings indicated that TMX and DOX degradation via GO@Fe3O4@CeO2 photocatalyst could achieve 97% within 60 min and 98% within 90 min, respectively.

description: Measurement of the average values of the input and output powers of a device can give insight into the transfer function (TF) of that device, but this approach usually hides the real impact of certain propagation phenomena. However, to the best of our knowledge, measurements of the TF of nonlinear optical loop mirrors have always been carried out using this approach [1-3], which may lead to underestimating the impact of dispersive and nonlinear effects. Here we present the experimental measurement of the TF of a nonlinear optical loop mirror (NOLM), made from the experimental measurements of the input and output intensity profiles of the device, using a frequency-resolved optical gating (FROG) technique [4-6]. Our approach clearly highlights the impact of dispersion effects and Kerr nonlinearity on the NOLM's TF.

description: Program synthesis is the process of generating a computer program following a set of specifications, which can be a high-level description of the problem and/or a set of input-output examples. The synthesis can be modeled as a search problem in which the search space is the set of all the programs valid under a grammar. As the search space is vast, brute force is usually not viable and search heuristics, such as genetic programming, also have difficulty navigating it without any guidance. In this paper we present HOTGP, a new genetic programming algorithm that synthesizes pure, typed, and functional programs. HOTGP leverages the knowledge provided by the rich data-types associated with the specification and the built-in grammar to constrain the search space and improve the performance of the synthesis. The grammar is based on Haskell's standard base library (the synthesized code can be directly compiled using any standard Haskell compiler) and includes support for higher-order functions, $λ$-functions, and parametric polymorphism. Experimental results show that, when compared to $6$ state-of-the-art algorithms using a standard set of benchmarks, HOTGP is competitive and capable of synthesizing the correct programs more frequently than any other of the evaluated algorithms.

description: The enhancement of a cryogenic radio frequency 22 pole trap instrument by the addition of ring electrodes is presented in detail. The ring electrodes tightly surround the poles and only a fraction of the applied electric potential penetrates to the trap axis, facilitating the fine control of slow cold ions. A precise computational model, describing the effective mechanical potential created by the applied static and rf fields, governing the ion behaviour, is employed to demonstrate and understand the operation of our setup. The use of ring electrodes for improved extraction of cold stored ions is shown. Variable trapping potentials, placed on one ring electrode, can be used to control the evaporation of only those $\text{H}^+$ ions from the trap, whose kinetic energy exceeds the barrier. This ring electrode trapping opens new possibilities to study processes of minimal kinetic energy release, e. g. spin exchange. We propose a robust modified method for the determination of temperature dependent ion molecule reaction rates, resistant to effects caused by neutral gas freezing and demonstrate it on the reaction of $\text{CO}^+$/$\text{CO}_2^+$ with $\text{H}_2$/$\text{D}_2$. Finally, the use of a supercontinuum laser for quick localisation of spectroscopic bands is examined on the $\text{N}_2^+$ Meinel system.

description: Measures of functional bone adaptation have often been applied to archaeological populations to reconstruct behaviours from the past. Although there has been increasing interest in women’s history and feminist archaeology, work that centres functional adaptation in women is still uncommon. The three most frequently used methods, entheseal changes (EC), long bone cross-sectional geometry (CSG), and degenerative joint changes (DJC), have rarely been applied in conjunction. Skeletal collections from Scotland have not been studied as frequently as others in Britain and activity data are in short supply. The primary aim of this thesis was to investigate patterns of skeletal changes compatible with social allocations of labour in urban medieval Scotland (c.800-1600 CE). The secondary aim was to determine the accuracy, value, and efficacy of using the three individual and concurrent methods. Sociohistorical, clinical, and palaeopathological data were synthesised to contextualise interpretations of functional adaptation. 204 individuals from medieval Edinburgh, Leith, St Andrews, Perth, and Dunbar were examined. The effects of gender and social status on bone were found via all three methods. Females showed evidence of a wide variety of strenuous labour that was similar for both high and low status groups. Women’s work was bimanual, but asymmetrical, and often performed below shoulder level using the elbow and forearm such as sweeping with a broom or holding an object with one arm. Evidence of labour in males was asymmetrical and consistent with frequent work at or above shoulder level. Men’s tasks were more often unimanual, specialised, and had less variety like carrying heavy objects on one shoulder. High status males, however, displayed less wear at the shoulder and more use of the forearm. Affluent and educated men likely performed more detailed and specialised sedentary tasks like writing or fine metalworking. This research confirms the value of clinical, anatomical, and kinesiological data to interpreting bone functional adaptation and highlights the effects of a highly gendered and stratified society on bone. This work adds to the growing field of feminist bioarchaeology and reveals the extraordinary contribution of women to the economy in urban medieval Scotland.

description: Nucleation in systems with a metastable liquid-gas critical point is the prototypical example of a two-step nucleation process, in which the appearance of the critical nucleus is preceded by the formation of a liquid-like density fluctuation. So far, the majority of studies on colloidal and protein crystallization have focused on one-component systems, and we are lacking a clear description of two-step nucleation processes in multicomponent systems, where critical fluctuations involve coupled density and concentrations inhomogeneities. Here, we examine the nucleation process of a binary mixture of patchy particles designed to nucleate into a diamond lattice. By combining Gibbs-ensemble simulations and direct nucleation simulations over a wide range of thermodynamic conditions, we are able to pin down the role of the liquid-gas metastable phase diagram on the nucleation process. In particular, we show that the strongest enhancement of crystallization occurs at an azeotropic point with the same stoichiometric composition of the crystal.

title: Studies on renovascular hypertension
Creators: name: Mackay, Alistair
Publisher: name: University of Glasgow
Year: 1980

description: Aspects of the pathogenesis, diagnosis, prognosis and management of renal artery stenosis have been studied in 86 hypertensive patients and in experimental animals. PATHOGENESIS: Mean exchangeable sodium was normal in patients with unilateral renal artery stenosis compared with normo-tensive controls, but the relation between exchangeable sodium and blood pressure was significant and negative (r = -0.62, p <0.001) in contrast to other forms of hypertension. Patients with the lowest exchangeable sodium had hyponatraemia, hypokalaemia, and secondary hyperaldosteronism - the "hyponatraemic hypertensive syndrome". Urinary sodium excretion from the unaffected kidney correlated positively (r = +0.51, p <0.01) with arterial pressure, possibly reflecting the phenomenon of pressure natriuresis. Patients who responded least well to subsequent surgery excreted least sodium from the unaffected kidney for a given arterial pressure, and maintained this relationship after surgery. The findings suggest an important role for arterial pressure in the control of sodium balance in contrast to Conn's syndrome where the roles are reversed. Before surgery arterial pressure was disproportionately high for a given plasma angiotensin II concentration in patients with unilateral renal artery stenosis in comparison with normal individuals infused with angiotensin II. After successful surgery this relation fell towards normal, consistent with a slow pressor action of angiotensin II in renovascular hypertension. Cigarette smoking was found to be significantly commoner (p <0.001) in patients with non-malignant hypertension and renal artery stenosis (84% smoked) than in age- and sex-matched controls with non-malignant hypertension without renal artery stenosis who were inpatients (46% smoked) or were attending the Glasgow Blood Pressure Clinic (44% smoked). The differences were significant for men and women separately, and for subgroups with renal artery occlusion, fibromuscular hyperplasia, and stenosis due to atheroma. 91% of patients with renal artery stenosis and malignant-phase hypertension at the time of presentation also smoked. Fibromuscular hyperplasia is one cause of renal artery stenosis whose aetiology remains obscure. Of 23 patients with this condition 21 were women, but no relationship between fibromuscular hyperplasia and pregnancy could be established. The right renal artery was involved twice as often as the left, perhaps reflecting a greater, degree of nephroptosis on that side.

description: PER1 and PER2 are among the class A β-lactamase enzymes, which have evolved clinically to form antibiotic resistance and have significantly expanded their spectrum of activity. Hence, there is a need to study the clinical mutation responsible for such β-lactamase mediated antibiotic resistance. Alterations in catalytic centre and Ω-loop structure could be the cause of antibiotic resistance in these β-lactamase enzymes. Structural and functional alterations are caused due to mutations on or near the catalytic centre, which results in active site plasticity and are responsible for its expanded spectrum of activity in these class A β-lactamase enzymes. Multiple sequence alignment, structure, kinetic, molecular docking, MMGBSA and molecular dynamic simulation comparisons were done on 38 clinically mutated and wild class A β-lactamase enzymes. This work shows that PER1 and PER2 enzymes contains most unique mutations and have altered Ω-loop structure, which could be responsible for altering the structure-activity relationship and extending the spectrum of activity of these enzymes. Alterations in molecular docking, MMGBSA, kinetic values reveals the modification in the binding and activity of these clinically mutated enzymes with antibiotics. Further, the cause of these alterations can be revealed by active site interactions and H-bonding pattern of these enzymes with antibiotics. Met69Gln, Glu104Thr, Tyr105Trp, Met129His, Pro167Ala, Glu168Gln, Asn170His, Ile173Asp and Asp176Gln mutations were uniquely found in PER1 and PER2 enzymes. These mutations occurs at catalytic important residues and results in altered interactions with β-lactam antibiotics. Hence, these mutations could be responsible for altering the structure-activity of PER1 and PER2 enzymes. Communicated by Ramaswamy H. Sarma

description: Let $\mathfrak{g}$ be a Leibniz algebra and $E$ a vector space containing $\mathfrak{g}$ as a subspace. All Leibniz algebra structures on $E$ containing $\mathfrak{g}$ as a subalgebra are explicitly described and classified by two non-abelian cohomological type objects: ${\mathcal H}{\mathcal L}^{2}_{\mathfrak{g}} \, (V, \, \mathfrak{g})$ provides the classification up to an isomorphism that stabilizes $\mathfrak{g}$ and ${\mathcal H}{\mathcal L}^{2} \, (V, \, \mathfrak{g})$ will classify all such structures from the view point of the extension problem - here $V$ is a complement of $\mathfrak{g}$ in $E$. A general product, called the unified product, is introduced as a tool for our approach. The crossed (resp. bicrossed) products between two Leibniz algebras are introduced as special cases of the unified product: the first one is responsible for the extension problem while the bicrossed product is responsible for the factorization problem. The description and the classification of all complements of a given extension $\mathfrak{g} \subseteq \mathfrak{E} $ of Leibniz algebras are given as a converse of the factorization problem. They are classified by another cohomological object denoted by ${\mathcal H}{\mathcal A}^{2}(\mathfrak{h}, \mathfrak{g} \, | \, (\triangleright, \triangleleft, \leftharpoonup, \rightharpoonup))$, where $(\triangleright, \triangleleft, \leftharpoonup, \rightharpoonup)$ is the canonical matched pair associated to a given complement $\mathfrak{h}$. Several examples are worked out in details.

description: The tight-binding method is employed to investigate the effects of three typical in-plane electric fields on the electronic structure of a triangular zigzag graphene quantum dot. The calculation shows that the single-electron eigenstates evolute independently in two subspaces no matter how the electric fields change. The electric field with fixed-geometry gates chooses several scattered parts of the zero-energy eigenspace as the new zero-energy eigenstates, regardless of the field strength. Moreover, the new zero-energy eigenstates remain unchanged and the associated levels are linear as the field strength. In contrast, the new nonzero-energy eigenstates mix mutually and the associated levels are nonlinear as the field strength. By comparing the effects of three electric fields, we demonstrate that the degeneracy of the zero-energy eigenstates accounts for the linearity of the associated levels.

description: Synthesis of a series of new urea and thiourea derivatives of 2-pyridyl piperazine was accomplished by reacting various isocyanates and isothiocyanates in the presence of triethylamine (TEA) at 50 °C. All the title compounds were obtained in high yields and their structures were characterized by IR, 1H, 13C NMR, Mass spectral, and Elemental analysis. The synthesized compounds were screened for in vitro and in silico antioxidant and antimicrobial activities. All the title compounds exhibited potent antioxidant and antimicrobial activities. Out of all, 2c and 2f against DPPH, H2O2 and Nitro oxide have exhibited significant activity and the levels of activity were higher than the reference compounds, ascorbic acid and BHT. Whereas 2a, 2c, 2f and 2j have shown prominent activity in terms of zone of inhibition against all the microbial strains tested than the standards such as levofloxacin and nystatin. In addition in silico studies also conveyed the same that is 2a, 2c, 2f and 2j have displayed the highest binding energies against peroxiredoxins and DNA gyrase protein than the standards akin to the rest of the compounds. In overall, 2c and 2f have exhibited most promising antioxidant and antimicrobial activity than the rest of the title compounds in vitro and in silico. Hence, 2c and 2f will stand as a lead and promising antioxidant and antimicrobial drug candidates in future. Communicated by Ramaswamy H. Sarma

description: Das Projekt "Open Data Format" entwickelt im Rahmen von KonsortSWD der NFDI ein offenes Datenformat, um den Austausch und die Nachnutzung von Forschungsdaten zu verbessern und den Zugang zu Dokumentationsmaterialen unmittelbar über die Statistik-Software zu ermöglichen. Gegenwärtig verwenden Sozialwissenschaftler:innen zur Analyse der Daten verschiedene und teilweise proprietäre Software, die Metadaten auf unterschiedliche Weise verarbeitet. Datenformate von statistischen Softwarepaketen, sind nur teilweise kompatibel und stellen ein Hindernis für Replikationsstudien dar. Insbesondere gefährden proprietäre Datenformate die in den FAIR-Prinzipien verankerte Forderung nach Interoperabilität. Darüber hinaus ist das Potential verfügbarer Metadaten für Datennutzer:innen nicht ausgeschöpft. Das Offene Datenformat kann mit mehrsprachigen Metadaten sowie weiterführenden Links zu Datenportalen angereichert werden, was den direkten Zugang zu Dokumentationsmaterialien über die Statistik-Software selbst ermöglicht. Der Vortrag gibt einen Einblick in den aktuellen Arbeitsstand des Projektes, wie die Spezifikation des Metadaten Profils sowie die Entwicklung von Import- und Export-Filtern für die Statistik-Programme R und Stata.

description: Sophisticated analysis of modern large-scale structure surveys requires mock catalogs. Mock catalogs are used to optimize survey design, test reduction and analysis pipelines, make theoretical predictions for basic observables and propagate errors through complex analysis chains. We present a new method, which we call "quick particle mesh", for generating many large-volume, approximate mock catalogs at low computational cost. The method is based on using rapid, low-resolution particle mesh simulations that accurately reproduce the large-scale dark matter density field. Particles are sampled from the density field based on their local density such that they have N-point statistics nearly equivalent to the halos resolved in high-resolution simulations, creating a set of mock halos that can be populated using halo occupation methods to create galaxy mocks for a variety of possible target classes.

description: The joint effect of gravity and thermal misbalance on the dynamics of acoustic-gravity waves (AGW) in the solar atmosphere is considered. It is shown that the heating and cooling taken in the form of power functions lead to the linear dependence of stationary temperature profile. Estimates of the ratio of the characteristic length associated with thermal processes to the gravitational height show a predominant influence of thermal processes in the temperature range up to 2 MK and a comparable influence on the dynamics of AGW in the range from 2 to 10 MK. A study of the dispersion properties of AGW in an isothermal atmosphere showed that in regimes with an overwhelming influence of thermal processes, the acoustic cut-off frequency decreases up to $\sqrtγ$ times. At the same time, the maximum frequency of the gravitational mode (analog of the Brunt-Vaisala frequency in the medium without non-adiabatic heating and cooling) decreases with increasing power of thermal processes, and then the gravitational mode can become purely oscillatory.

Consistency of the tachyon warm inflationary universe models

description: This study concerns the consistency of the tachyon warm inflationary models. A linear stability analysis is performed to find the slow-roll conditions, characterized by the potential slow-roll (PSR) parameters, for the existence of a tachyon warm inflationary attractor in the system. The PSR parameters in the tachyon warm inflationary models are redefined. Two cases, an exponential potential and an inverse power-law potential, are studied, when the dissipative coefficient $Γ=Γ_0$ and $Γ=Γ(ϕ)$, respectively. A crucial condition is obtained for a tachyon warm inflationary model characterized by the Hubble slow-roll (HSR) parameter $ε_{_H}$, and the condition is extendable to some other inflationary models as well. A proper number of e-folds is obtained in both cases of the tachyon warm inflation, in contrast to existing works. It is also found that a constant dissipative coefficient $(Γ=Γ_0)$ is usually not a suitable assumption for a warm inflationary model.

description: Theoretical analyses of two phenothiazine derivatives, 10-[3-(dimethylamino)-2-methylpropyl]phenothiazine-2-carbonitrile (CYM) and 2-[4-[3-(2-chlorophenothiazin-10-yl)propyl]piperazin-1-yl]ethanol (PAZ) are reported using density functional theory (DFT) and molecular dynamics (MD) simulations. Spectroscopic studies, different electronic and chemical parameters are predicted. Red and yellow in electrostatic potential plot is in rings and oxygen atom in PAZ and C≡N and rings in CYM are sensitive to nucleophilic attacks. The blue in hydrogen atoms refer to electrophilic attack in both PAZ and CYM. Stability of the protein–ligand complex formed with these derivatives and angiotensin-converting enzyme 2 (ACE2) was investigated using MD simulation. Radius of gyration of C-alpha atom of 6VW1 displayed the conformational convergence toward a compact structure leading to stable 6VW1–ligand complex which are also in agreement with root mean square fluctuation (RMSF) values. Localized area predicts reactive sites for Au and H2O molecules interaction with these compounds for further practical applications. Charge density is localized on both molecules and also tries to move toward Au–Au dimer and water molecule and such they are expected to contribute to the sensing performance.

description: In this paper, we introduce the $L_p$ geominimal surface area for all $-n\neq p<1$, which extends the classical geominimal surface area ($p=1$) by Petty and the $L_p$ geominimal surface area by Lutwak ($p>1$). Our extension of the $L_p$ geominimal surface area is motivated by recent work on the extension of the $L_p$ affine surface area -- a fundamental object in (affine) convex geometry. We prove some properties for the $L_p$ geominimal surface area and its related inequalities, such as, the affine isoperimetric inequality and a Santaló style inequality. Cyclic inequalities are established to obtain the monotonicity of the $L_p$ geominimal surface areas. Comparison between the $L_p$ geominimal surface area and the $p$-surface area is also provided.

description: We consider supersymmetric field theories on compact manifolds M and obtain constraints on the parameter dependence of their partition functions Z_M. Our primary focus is the dependence of Z_M on the geometry of M, as well as background gauge fields that couple to continuous flavor symmetries. For N=1 theories with a U(1)_R symmetry in four dimensions, M must be a complex manifold with a Hermitian metric. We find that Z_M is independent of the metric and depends holomorphically on the complex structure moduli. Background gauge fields define holomorphic vector bundles over M and Z_M is a holomorphic function of the corresponding bundle moduli. We also carry out a parallel analysis for three-dimensional N=2 theories with a U(1)_R symmetry, where the necessary geometric structure on M is a transversely holomorphic foliation (THF) with a transversely Hermitian metric. Again, we find that Z_M is independent of the metric and depends holomorphically on the moduli of the THF. We discuss several applications, including manifolds diffeomorphic to S^3 x S^1 or S^2 x S^1, which are related to supersymmetric indices, and manifolds diffeomorphic to S^3 (squashed spheres). In examples where Z_M has been calculated explicitly, our results explain many of its observed properties.
