description: We have performed an angle-resolved photoemission spectroscopy (ARPES) study of Nd$_{1.85}$Ce$_{0.15}$CuO$_{4}$ (NCCO) in order to elucidate the origin of the high-energy kink (HEK) observed in the high-$T_{\rm c}$ superconductors (HTSCs). The energy scale of the HEK in NCCO is large compared with that in hole-doped HTSCs, consistent with previous ARPES studies. From measurement in a wide momentum region, we have demonstrated that between the hole- and electron-doped HTSCs the energy position of the HEK is shifted approximately by the amount of the chemical potential difference. Also, we have found that around $(π, 0)$ the HEK nearly coincides with the band bottom while around the node the band reaches the incoherent region and the HEK appears at the boundary between the coherent and incoherent regions.

description: Explicitly orbital-dependent approximations to the exchange-correlation energy functional of density functional theory typically not only depend on the single-particle Kohn-Sham orbitals but also on their occupation numbers in the ground state Slater determinant. The variational calculation of the corresponding exchange-correlation potentials with the Optimized Effective Potential (OEP) method therefore also requires a variation of the occupation numbers with respect to a variation in the effective single-particle potential, which is usually not taken into account. Here it is shown under which circumstances this procedure is justified.

Small island governance and global-local change in King Island, Tasmania
Creators: name: Jones, ER
Publisher: name: University Of Tasmania
Year: 2023

description: It is claimed that small islands fall prey to powerful forces that transform place and life, creating major political, economic, social and environmental challenges simultaneously global and local in their reach and impact. This research examines whether, how and to what extent modes of governing fail or succeed to support such challenges of change. A qualitative work positioned between island studies and cultural geography, it fuses notions of island, place and governance in a case study that examines how members of a small island population dealt with global-local change. The setting was King Island, remote dependant of Australian island state Tasmania. Three methods were used: community observation by the researcher, analysis of primary and secondary documentary evidence, and the interpretation of three rounds of interviews conducted with King Islanders over six months. Data were first categorised, described and analysed in terms of the strengths, weaknesses, opportunities and threats or challenges that islanders perceived in relation to quality of life. Second, four challenges of chief significance to participants were examined in depth: governance, population, land use and tenure, and climate. Hermeneutic analysis of these four cases points to both failures and successes to manage global-local change in the short term, which participants explained in terms of particular mindsets in King Island contoured by local (island) place, and tensions over relational place with two powerful sovereign governments. Examples of the potential of governance‚ÄövÑvÆdealt with in depth in the final discussion‚ÄövÑvÆsuggest that both failures and successes of various kinds and intensities are possible in small island systems. Such insights stand as conclusive and object lessons in two ways. First, what appears to be governing failure can lead to change and opportunity for growth in governing capacity and outcomes for the common good. Second, occupants of small islands can indeed find ways to manage their global-local challenges.

description: A Lorentz and gauge symmetry preserving regularization method is proposed in 4 dimension based on momentum cutoff. We use the conditions of gauge invariance or freedom of shift of the loop-momentum to define the evaluation of the terms carrying Lorentz indices, e.g. proportional to k_μk_ν. The remaining scalar integrals are calculated with a four dimensional momentum cutoff. The finite terms (independent of the cutoff) are unambiguous and agree with the result of dimensional regularization.

description: Background: HER2 is considered as one of the most important, predictive biomarkers in oncology. The diagnosis of HER2 positive cancer types such as breast- and gastric cancer is usually based on immunohistochemical HER2 staining of tumour tissue. However, the current immunohistochemical methods do not provide localized information about HER2's functional state. In order to generate signals leading to cell growth and proliferation, the receptor spontaneously forms homodimers, a process that can differ between individual cancer cells. Materials and methods: HER2 overexpressing tumour cells were dissociated from formalin-fixed paraffin-embedded (FFPE) patient's biopsy sections, subjected to a heat-induced antigen retrieval procedure, and immobilized on microchips. HER2 was specifically labelled via a two-step protocol involving the incubation with an Affibody-biotin compound followed by the binding of a streptavidin coated quantum dot (QD) nanoparticle. Cells with membrane bound HER2 were identified using fluorescence microscopy, coated with graphene to preserve their hydrated state, and subsequently examined by scanning transmission electron microscopy (STEM) to obtain the locations at the single molecule level. Label position data was statistically analysed via the pair correlation function, yielding information about the presence of HER2 homodimers. Results: Tumour cells from two biopsies, scored HER2 3+, and a HER2 negative control sample were examined. The specific labelling protocol was first tested for a sectioned tissue sample of HER2-overexpressing tumour. Subsequently, a protocol was optimized to study HER2 homodimerization in single cells dissociated from the tissue section. Electron microscopy data showed membrane bound HER2 in average densities of 201-689 proteins/μm2. An automated, statistical analysis of well over 200,000 of measured protein positions revealed the presence of HER2 homodimers in 33 and 55% of the analysed images for patient 1 and 2, respectively. Conclusions: We introduced an electron microscopy method capable of measuring the positions of individually labelled HER2 proteins in patient tumour cells from which information about the functional status of the receptor was derived. This method could take HER2 testing a step further by examining HER2 homodimerization directly out of tumour tissue and may become important for adjusting a personalized antibody-based drug therapy. © 2019 The Author(s).
Effective slip boundary conditions for arbitrary periodic surfaces: The surface mobility tensor

description: In a variety of applications, most notably microfluidic design, slip-based boundary conditions have been sought to characterize fluid flow over patterned surfaces. We focus on laminar shear flows over surfaces with periodic height fluctuations and/or fluctuating Navier scalar slip properties. We derive a general formula for the "effective slip", which describes equivalent fluid motion at the mean surface as depicted by the linear velocity profile that arises far from it. We show that the slip and the applied stress are related linearly through a tensorial mobility matrix, and the method of domain perturbation is then used to derive an approximate formula for the mobility law directly in terms of surface properties. The specific accuracy of the approximation is detailed, and the mobility relation is then utilized to address several questions, such as the determination of optimal surface shapes and the effect of random surface fluctuations on fluid slip.

The effect of some environmental factors upon the CO₂ exchange and the effect of photoperiod upon the development of Hordeum vulgare L.
Creators: name: Hubbard, William Frederick
Publisher: name: University of British Columbia
Year: 2011

description: Experiments were conducted with a Blue M "Vapor-Temp" controlled environment apparatus to show the effect of temperature, light intensity, relative humidity and age upon the rate of CO₂ exchange for twelve barley varieties. All varieties showed an increase in CO₂ uptake with an increase in temperature to a certain optimum, varying with variety. When the temperature was raised above this point, the rate of CO₂ uptake decreased. In all varieties tested the rate of CO₂ uptake increased as light intensity was increased up to 2400 ft. candles. Three out of four varieties tested showed significant changes in rate of CO₂ uptake with changes in relative humidity. All varieties tested showed an initial decrease in rate of CO₂ uptake per unit leaf area as the plants aged from 15 to 30 days. Above this age there was little change in rate of CO₂ exchange. Experiments were also conducted in photoperiod chambers to determine the developmental response of different barley varieties to different photoperiods. It was found that the varieties differed in overall response to photoperiod. Within a variety there was a difference in rate of development between plants subjected to different photoperiods. The optimal photoperiod for head differentiation and for head appearance was 21 or 24 hours for all varieties.
Video-based intervention for individuals with autism
Creators: name: Rayner, CS
Publisher: name: University Of Tasmania
Year: 2023

description: This doctoral research investigated video-based intervention (VBI) for individuals with autism. Without effective intervention, individuals with autism are likely to experience difficulties with functioning at home, progressing at school, and becoming independent in the community. VBI is a promising educational approach for this population. However, this thesis highlights several important practical and theoretical questions relating to VBI for individuals with autism that have, to date, remained unanswered. In particular, this doctoral research focuses on whether there is a positive relationship between a participant's imitation ability and the effectiveness of VBI. It also explores the question of whether one type of model (an adult, a peer, a sibling, or the participant themselves) is more effective than the others. Five boys diagnosed with autism and aged between nine and 15 years participated in the three intervention studies. Each study utilised a single-case research design. In the first study, the participant's imitation assessment (interview and observation-based formats) suggested that he was suited to VBI. As a result of the video modelling (VM) procedures (with an adult-as-model), the participant's completion of two daily living tasks improved. In the second study, no improvements were observed across three target behaviours as a result of either the adult-as-model or the sibling-as-model VBI conditions. The findings of the second study could be explained, at least in part, by limitations in the participant's imitation skills, as evidenced by his imitation assessment scores. In the third study, no differences in the effectiveness of the adult-as-model compared with the peer or sibling-as-model conditions were evident for teaching the three boys to tie a shoelace knot. Also, a backward chaining procedure was found to be more effective than the video prompting procedures. Imitation assessment scores, as well as adaptive behaviour age equivalents and severity of autistic impairment scores, could be used to explain differences in acquisition of the target behaviour across participants in the third study. Overall, the findings are consistent with the hypothesis that participants who demonstrate stronger imitation skills are more likely to benefit from VBI. No consistent differences between the effectiveness of sibling, peer, or adult models were identified. The findings of the three studies are considered in terms of how these and other variables influence the effectiveness of VBI. The contribution of these findings to the field and their implications for both research and practice are discussed.

description: Hot dense helium is studied with first-principles computer simulations. By combining path integral Monte Carlo and density functional molecular dynamics, a large temperature and density interval ranging from 1000 to 1000000 K and 0.4 to 5.4 g/cc becomes accessible to first-principles simulations and the changes in the structure of dense hot fluids can be investigated. The focus of this article are pair correlation functions between nuclei, between electrons, and between electrons and nuclei. The density and temperature dependence of these correlation functions is analyzed in order to describe the structure of the dense fluid helium at extreme conditions.

description: Abstract

World Health Organization (WHO), in 2020, ovarian cancer ranks as the fourth most common cancer found in women in the world after breast cancer, colorectal cancer, and uterine corpus cancer. More than 200,000 deaths are recorded annually, which are predominantly women with weak economies in both developing and developed countries. The country with the highest number is sub-Saharan Africa, including South Africa (40/100,000). In Africa. Ranks sixth in Indonesia as a cancer disease. This type of research is a case control study with a retrospective approach (retrospective study), namely research that explains the relationship between the effect (ovarian cancer) and internal risks (family history, parity), and external risks (use of oral contraceptives, Drugs that increase fertility) The results of the study illustrate that there is a relationship between family history and the incidence of ovarian cancer at Melati Perbaungan General Hospital Medan.Based on the results of the study it was found that the variables associated with the incidence of ovarian cancer in the Pirngadi Medan General Hospital, family history, were p=0.000 (p<0.05) with OR=12.00, parity p=0.001 (p<0, 05) with OR=9.07, contraceptive use p=0.001 (p<0.05) with OR=11.08 and use of fertility drugs p=0.027 (p<0.05) with OR=4.50).    It is suggested to health workers that promotion efforts be made to the public regarding factors related to the incidence of ovarian cancer but primary prevention efforts also need to be carried out. And to mothers who have paid attention to and care about the factors that influence the incidence of ovarian cancer and good health practices are expected to continue to maintain them.

description: The non-linear effects operating at the recombination epoch generate a non-Gaussian signal in the CMB anisotropies. Such a contribution is relevant because it represents a major part of the second-order radiation transfer function which must be determined in order to have a complete control of both the primordial and non-primordial part of non-Gaussianity in the CMB anisotropies. We provide an estimate of the level of non-Gaussianity in the CMB arising from the recombination epoch which shows up mainly in the equilateral configuration. We find that it causes a contamination to the possible measurement of the equilateral primordial bispectrum shifting the minimum detectable value of the non-Gaussian parameter f^equil_NL by Delta f^equil_NL= O(10) for an experiment like Planck.

Συνακόλουθα, περιλαμβάνει και τη λειτουργία των διακυβερνητικών θεσμών στον διεθνή χώρο. Ως βασική περίπτωση προς ανάλυση τίθεται το διεθνικό οργανωμένο έγκλημα. Η έρευνα εστιάζει στον εντοπισμό και την εξήγηση των τρόπων με τους οποίους ένα διεθνικό φαινόμενο όπως το οργανωμένο έγκλημα εμφανίζεται και αναπτύσσεται στο διεθνές σύστημα, συνδέεται με τα κράτη και τους διεθνείς θεσμούς και προκαλεί ορισμένες συνέπειες.

Natural salt licks as a part of the ecology of the mountain goat
Creators: name: Hebert, Daryll Marvin
Publisher: name: University of British Columbia
Year: 2011

description: The role of natural earth licks in the ecology of the mountain goat (Oreamnos americanus (Blainville)) was studied during the summers of 1965 and 1966 in the Rocky Mountain Trench of southern B.C. The patterns of movements of the animals were determined as they used the licks and the vegetation, lick soils and blood serum were analyzed with respect to sodium content. The predicated use of licks as suggested by other workers involves the idea that sodium may be the attracting element. The present study examined seasonal and differential patterns of movement, along with periodicity of use, in order to determine the resultant interplay of animal movement and sodium and water content of the vegetation. The goat encounters such additional risks as predation, parasitism, hunting and joint use while using the lick seasonally. Since the goats use the lick differentially in time, each sex is affected to a different degree by the above factors. Differential use also produces characteristic patterns of grouping and molting. Periodicity of use occurred mainly in the afternoon, although distance travelled and complexity of the lick may affect time of entry, length of stay and group size. The frequency of use differed at each lick, with the average time of use by an individual being one to three weeks. Environmental factors such as temperature and weather appear to regulate the movement to and from the lick. Analysis of the vegetation revealed that sodium was extremely low and that potassium was present in sufficient quantities to meet the requirements of the animal. No significant trends were found to exist from spring to fall or due to changes in elevation, as far as sodium and total ash were concerned. Observations indicated that animals select certain licks over others and select sites within a lick. These high licking sites were shown to have a higher sodium content. Newly established licks had a higher sodium content than did old licks, however, highly preferred sites were not always higher in calcium, phosphorus or cobalt. A normal range of serum sodium values was established for the goat but due to the regulatory function of the kidney, changes in serum sodium due to lick use could not be detected. Serum sodium decreased with age. A female with a kid had a low serum value. It appears that the level of deficiency causing the craving is not sufficient to show up in serum analysis. Animals died during trapping operations and a selenium deficiency was suspected. Gross symptoms approximated those attributed to white muscle disease and the vegetation contained selenium in amounts which are known to cause this myopathy.

Students' understanding of statistical inference : implications for teaching
Creators: name: Reaburn, Robyn
Publisher: name: University Of Tasmania
Year: 2023

description: It was of concern to the researcher that students were successfully completing introductory tertiary statistics units (if success is measured by grades received), without having the ability to explain the principles behind statistical inference. In other words, students were applying procedural knowledge (surface learning) without concurrent conceptual knowledge. This study had the aim of investigating if alternative teaching strategies could assist students in gaining the ability to explain the principles behind two tools of statistical inference: P-values and confidence intervals for the population mean. Computer simulations were used to introduce students to statistical concepts. Students were also introduced to alternative representations of hypothesis tests, and were encouraged to give written explanations of their reasoning. Time for reflection, writing and discussion was also introduced into the lectures. It was the contention of the researcher that students are unfamiliar with the hypothetical, probabilistic reasoning that statistical inference requires. Therefore students were introduced to this form of reasoning gradually throughout the teaching semester, starting with simple examples that the students could understand. It was hoped that by the use of these examples students could make connections that would form the basis of further understanding. It was found that in general, students' understanding of P-values, as demonstrated by the reasoning used in their written explanations, did improve over the four semesters of the study. Students‚ÄövÑvº understanding of confidence intervals also improved over the time of the study. However for confidence intervals, where simple examples were more difficult to find, student understanding did not improve to the extent that it did for P-values. It is recommended that statistics instructors need to appreciate that tertiary students, even those with pre-tertiary mathematics, may not have a good appreciation of probabilistic processes. Students will also be unfamiliar with hypothetical, probabilistic reasoning, and will find this difficult. Statistics instructors, therefore, need to find connections that students can make to more familiar contexts, use alternative representations of statistical processes, and give students time to reflect and write on their work.

Here, the first molecularly defined cobalt pincer complex is disclosed for the dehydrogenation of formic acid in aqueous medium under mild conditions. Crucial for catalytic activity is the use of the specific complex 3. Compared to related ruthenium and manganese complexes 7 and 8, this optimal cobalt complex showed improved performance. DFT computations support an innocent non-classical bifunctional outer-sphere mechanism on the triplet state potential energy surface. © 2019 The Authors. Published by Wiley-VCH Verlag GmbH & Co.

By applying an external magnetic field in proximity of a Feshbach resonance, we adjust the free-space scattering length to observe a series of resonances in mixed dimensions. By monitoring 3-body inelastic losses, we measure the magnetic field values corresponding to the mix-dimensional scattering resonances and find a good agreement with the theoretical predictions based on simple energy considerations.

description: A mechanism for generating metric perturbations in inflationary models is considered. Long-wavelength inhomogeneities of light scalar fields in a decoupled sector may give rise to superhorizon fluctuations of couplings and masses in the low-energy effective action. Cosmological phase transitions may then occur that are not simultaneous in space, but occur with time lags in different Hubble patches that arise from the long-wavelength inhomogeneities. Here an interesting model in which cosmological perturbations may be created at the electroweak phase transition is considered. The results show that phase transitions may be a generic source of non-Gaussianity.

description: Nonlinear optical properties and carrier relaxation dynamics in graphene, suspended in three different solvents, are investigated using femtosecond (80 fs pulses) Z-scan and degenerate pumpprobe spectroscopy at 790 nm. The results demonstrate saturable absorption property of graphene with a nonlinear absorption coefficient, $beta$, of ~2 to 9x10^-8 cm/W. Two distinct time scales associated with the relaxation of photoexcited carriers, a fast one in the range of 130-330 fs (related to carrier-carrier scattering) followed by a slower one in 3.5-4.9 ps range (associated with carrier-phonon scattering) are observed.

description: The effect of chemical solvents on the wetting state of laser-structured surfaces over time is systematically examined in this paper. By using a 300-fs laser, nanostructures were generated on Ti6Al4V, subsequently cleaned in an ultrasonic bath with different solvents and stored in ambient air. The static contact angle showed significant differences for cleaning with various solvents, which, depending on the applied cleaning and time, amounted up to 100°. X-ray photoelectron spectroscopy analyses reveal that the cleaning of the laser-structured surfaces affects the surface chemistry and the aging behavior of the surfaces, even with highly volatile solvents. The effect of the chemical surface modification is particularly noticeable when using alcohols for cleaning, which, due to their OH groups, cause highly hydrophilic behavior of the surface after one day of storage. Over the course of 14 days, enrichment with organic groups from the atmosphere occurs on the surface, which leads to poorer wetting on almost every structured surface. In contrast, the cleaning in hexane leads to a fast saturation of the surface with long-chain carbon groups and thus to a time-independent hydrophobic behavior.

description: We study quantum interference corrections to the conductivity in (Ga,Mn)As ferromagnetic semiconductors using a model with disordered valence band holes coupled to localized Mn moments through a p-d kinetic-exchange interaction. We find that at Mn concentrations above 1% quantum interference corrections lead to negative magnetoresistance, i.e. to weak localization (WL) rather than weak antilocalization (WAL). Our work highlights key qualitative differences between (Ga,Mn)As and previously studied toy model systems, and pinpoints the mechanism by which exchange splitting in the ferromagnetic state converts valence band WAL into WL. We comment on recent experimental studies and theoretical analyses of low-temperature magnetoresistance in (Ga,Mn)As which have been variously interpreted as implying both WL and WAL and as requiring an impurity-band interpretation of transport in metallic (Ga,Mn)As.

Non-Linear tomographic inversion of active source seismic data: An investigation of the basement structure of Eastern Tasmania
Creators: name: Lorimer, T
Publisher: name: University Of Tasmania
Year: 2023

description: A genetic algorithm has been developed for the inversion of seismic traveltime data and applied to a tomographic investigation of central-eastern Tasmania. The investigation used four shots and twelve stations across a 100 km east-west section of the post Devonian cover of the Tasmania Basin. This area lies across the inferred but poorly understood contact between the Eastern and Western Tasmanian Terranes, which has proven difficult to image in previous geophysical studies. The genetic algorithm developed in this project is portable across all parallel and non-parallel Unix-based computing platforms, and interfaces with an existing, ad- vanced, fast marching forward model code. The algorithm was applied both at low resolution with subsequent model refinement by a subspace inversion method in a two- step approach, and at higher resolution to directly invert the data using a one-step approach. The one-step implementation yielded superior exploration of the model space, and sufficient exploitation of the possible solutions when applied to the sparse noisy data acquired during the controlled source investigation. This demonstrates the viability of a one-step Monte-Carlo approach to seismic traveltime tomography in cases of sparse data coverage. The results of the inversions show a high velocity anomaly at 6 km depth and 147.4 degrees longitude, coincident with a long-wavelength magnetic anomaly, and is interpereted as an ultramafic unit of possible oceanic crustal affinity. This supports both thick and thin-skinned tectonic models with oceanic crust beneath the Eastern Tasmanian Terrane, though the thin-skinned scenario is preferred on the basis of ex- isting gravity data. A model is suggested in which this oceanic unit is part of the allochthonous boninite-tholeiite stack overlying the Western Tasmanian Terrane.

description: We investigate the impact of the tau and bottom Yukawa couplings on the transport dynamics for electroweak baryogenesis in supersymmetric extensions of the Standard Model. Although it has generally been assumed in the literature that all Yukawa interactions except those involving the top quark are negligible, we find that the tau and bottom Yukawa interaction rates are too fast to be neglected. We identify an illustrative "lepton-mediated electroweak baryogenesis" scenario in which the baryon asymmetry is induced mainly through the presence of a left-handed leptonic charge. We derive analytic formulae for the computation of the baryon asymmetry that, in light of these effects, are qualitatively different from those in the established literature. In this scenario, for fixed CP-violating phases, the baryon asymmetry has opposite sign compared to that calculated using established formulae.

2-Auslander algebras associated with reduced words in Coxeter groups

description: In this paper we investigate the endomorphism algebras of standard cluster tilting objects in the stably 2-Calabi-Yau categories $\Sub{Λ_w}$ with elements $w$ in Coxeter groups in \cite{BIRSc}. They are examples of the 2-Auslander algebras introduced in \cite{I1}. Generalizing work in \cite{GLS1} we show that they are quasihereditary, even strongly quasihereditary in the sense of \cite{R}. We also describe the cluster tilting object giving rise to the Ringel dual, and prove that there is a duality between $\Sub{Λ_w}$ and the category $\mathcal{F}(Δ)$ of good modules over the quasihereditary algebra. When $w = uv$ is a reduced word, we show that the 2-Calabi-Yau triangulated category $\underline{\Sub}Λ_v$ is equivalent to a specific subfactor category of $\underline{\Sub}Λ_w.$ This is applied to show that a standard cluster tilting object $M$ in $\Sub{Λ_w}$ and the cluster tilting object $Λ_w\oplusΩ{M}$ lie in the same component in the cluster tilting graph.

description: We define an extension of predicate logic, called Binding Logic, where variables can be bound in terms and in propositions. We introduce a notion of model for this logic and prove a soundness and completeness theorem for it. This theorem is obtained by encoding this logic back into predicate logic and using the classical soundness and completeness theorem there.

description: Abstract Today, aggressive verbal behavior is generally perceived as a threat to integrity and democratic quality of public discussions, including those online. However, we argue that, in more restrictive political regimes, communicative aggression may play constructive roles in both discussion dynamics and empowerment of political groups. This might be especially true for restrictive political and legal environments like Russia, where obscene speech is prohibited by law in registered media and the political environment does not give much space for voicing discontent. Taking Russian YouTube as an example, we explore the roles of two under-researched types of communicative aggression—obscene speech and politically motivated hate speech—within the publics of video commenters. For that, we use the case of the Moscow protests of 2019 against non-admission of independent and oppositional candidates to run for the Moscow city parliament. The sample of over 77,000 comments for 13 videos of more than 100,000 views has undergone pre-processing and vocabulary-based detection of aggression. To assess the impact of hate speech upon the dynamics of the discussions, we have used Granger tests and assessment of discussion histograms; we have also assessed the selected groups of posts in an exploratory manner. Our findings demonstrate that communicative aggression helps to express immediate support and solidarity. It also contextualizes the criticism towards both the authorities and regime challengers, as well as demarcates the counter-public.

description: We analyze an adaptive finite element/boundary element procedure for scalar elastoplastic interface problems involving friction, where a nonlinear uniformly monotone operator such as the p-Laplacian is coupled to the linear Laplace equation on the exterior domain. The problem is reduced to a boundary/domain variational inequality, a discretized saddle point formulation of which is then solved using the Uzawa algorithm and adaptive mesh refinements based on a gradient recovery scheme. The Galerkin approximations are shown to converge to the unique solution of the variational problem in a suitable product of L^p- and L^2-Sobolev spaces.
