Publisher: name: University of British Columbia
Year: 2013

description: Background: Obstructive sleep apnea (OSA) and obesity are major independent risk factors for cardiovascular disease; nearly 70% of OSA patients are obese. This thesis examines the vascular effects of sleep disordered breathing in a mouse model with diet-induced obesity. Markers of oxidative stress and inflammation were also determined in these mice. Methods: Mice were divided into four groups for 6 weeks: i) mice subjected to intermittent hypoxia alone (IH) ii) mice fed a high fat (60%) diet alone (HFIA), iii) mice subjected to intermittent hypoxia and a high fat diet and (HFIH) iv) mice subjected to intermittent air (IA) alone. Vasodilatory and contractility responses were examined in isolated aortas to assess changes in endothelial function. Markers of oxidative stress (MDA and TAC) and inflammation (CRP) levels were measured and finally, eNOS expression in the aortas was evaluated. Results: Only mice subjected to intermittent hypoxia and a high fat diet showed endothelial dysfunction. Intermittent hypoxia alone increased plasma oxidative stress and inflammatiory markers but adding high fat diet further increased those markers. High fat diet alone did not increase oxidative stress or inflammation. Total antioxidant capacity and aortic eNOS expression were not significantly different between the groups. Conclusion: there is a synergistic effect between intermittent hypoxia and high fat diet since only their combination of caused endothelial dysfunction. These data suggest that aortic endothelial dysfunction may be mediated by increased oxidative stress and inflammation.

description: For a real-valued function V from the Faddeev-Marchenko class, we prove the norm resolvent convergence, as εgoes to 0, of a family S_εof one-dimensional Schrödinger operators on the line of the form S_ε:= -D^2 + ε^{-2} V(x/ε). Under certain conditions the family of potentials converges in the sense of distributions to the first derivative of the Dirac delta-function, and then the limit of S_εmight be considered as a "physically motivated" interpretation of the one-dimensional Schrödinger operator with potential δ'.

description: Leopardus is a genus that, despite currently being widely distributed in South America, shows until now a fragmentary fossil record. Among Leopardus, L. pardalis is the largest species, having an historical range that includes tropical and subtropical habitats from southern U.S.A. to southern South America but, as usual in the ocelot lineage, fossil remains that can be interpreted with certainty are restricted to the Late Pleistocene of southern U.S.A. and Brazil. Here we present a new record (a fragment of right maxillary plus zygomatic with P4–M1; incomplete left mandible with the coronoid process, part of c1 alveolus and p3–m1; isolated right c1) from the Late Pleistocene of Arroyo Toropí, Corrientes province, Argentina. The bearing level was dated with Optically Stimulated Luminescence (OSL) to 98.4 ka (Marine Isotopic Stage, MIS 5c). Present environmental requirements of L. pardalis and climatic reconstructions carried out here suggest a compatible scenario with MIS 5 for this fossil, which is concordant with the associated dating (ca. 98.4 ka). Leopardus pardalis appears to be part of a subtropical fauna, with Tayassu pecari and Euphractus sexcinctus, which inhabited the region during warm and wet climatic events of MIS 5c. Phytoliths and other vertebrates are congruent with its presence, since the inferred conditions are similar to the present one. The new record is relevant not only because it is the first fossil record of the species for the Pleistocene of Argentina, but also because it is placed 1800 km south of the closest accurately identified published fossil.

Imbalanced Fermi Gases at Unitarity

description: We consider imbalanced Fermi gases with strong attractive interactions, for which Cooper-pair formation plays an important role. The two-component mixtures consist either of identical fermionic atoms in two different hyperfine states, or of two different atomic species both occupying only a single hyperfine state. In both cases, the number of atoms for each component is allowed to be different, which leads to a spin imbalance, or spin polarization. Two different atomic species also lead to a mass imbalance. Imbalanced Fermi gases are relevant to condensed-matter physics, nuclear physics and astroparticle physics. They have been studied intensively in recent years, following their experimental realization in ultracold atomic Fermi gases. The experimental control in such a system allows for a systematic study of the equation of state and the phase diagram as a function of temperature, spin polarization and interaction strength. In this review, we discuss the progress in understanding strongly-interacting imbalanced Fermi gases, where a main goal is to describe the results of the highly controlled experiments. We start by discussing Feshbach resonances, after which we treat the imbalanced Fermi gas in mean-field theory to give an introduction to the relevant physics. We encounter several unusual superfluid phases, including phase separation, gapless Sarma superfluidity, and supersolidity. To obtain a more quantitative description of the experiments, we review also more sophisticated techniques, such as diagrammatic methods and the renormalization-group theory. We end the review by discussing two theoretical approaches to treat the inhomogeneous imbalanced Fermi gas, namely the Landau-Ginzburg theory and the Bogoliubov-de Gennes approach.

description: Metoposaurids are some of the most commonly occurring tetrapods in non-marine Upper Triassic sediments in the northern hemisphere of Pangea. Since the first description of a metoposaurid in 1842, nearly two dozen species have been named, but many of these have been regarded with increasing skepticism by modern workers because of minor differences used to validate novel species and sometimes novel genera. More recent comprehensive descriptions and evaluations of intraspecific variation from several presumed monospecific bonebeds of metoposaurids have prompted reevaluation of holotypes due to variation in proposed apomorphies. Four metoposaurid species were named from the Popo Agie Formation exposures of Wyoming, U.S.A., but at present, only a single species, Anaschisma browni, is considered valid following a recent redescription of two of these taxa (An. browni and An. brachygnatha). The other two taxa, Borborophagus wyomingensis and Koskinonodon princeps, have not been redescribed since their original description in 1929. A redescription of the holotypes of these two taxa is presented here to assess their historic synonymy with An. browni and to provide a detailed, updated record of the Popo Agie Formation metoposaurids in light of a historic relative lack of attention compared with other North American deposits. Our confirmation of the conspecificity of all four Popo Agie Formation metoposaurids permits a detailed discussion of potential ontogenetic variation in the Popo Agie Formation metoposaurids and latitudinal variability in An. browni.

description: von Laue's theorem, as well as its generalized form, is strictly proved in detail for its sufficient and necessary condition (SNC). This SNC version of Laue's theorem is used to analyze the infinitely extended electrostatic field produced by a charged metal sphere in free space, and the static field confined in a finite region of space. It is shown in general that the total (Abraham = Minkowski) EM momentum and energy for the electrostatic field cannot constitute a Lorentz four-vector. A derivative von Laue's theorem, which provides a criterion for a Lorentz invariant, is also presented.

description: Let $Υ$ be a compact, negatively curved surface. From the (finite) set of all closed geodesics on $Υ$ of length $\leq L$, choose one, say $γ_{L}$, at random and let $N (γ_{L})$ be the number of its self-intersections. It is known that there is a positive constant $κ$ depending on the metric such that $N (γ_{L})/L^{2} \rightarrow κ$ in probability as $L\rightarrow \infty$. The main results of this paper concern the size of typical fluctuations of $N (γ_{L})$ about $κL^{2}$. It is proved that if the metric has constant curvature -1 then typical fluctuations are of order $L$, in particular, $(N (γ_{L})-κL^{2})/L$ converges weakly to a nondegenerate probability distribution. In contrast, it is also proved that if the metric has variable negative curvature then fluctuations of $N (γ_{L})$ are of order $L^{3/2}$, in particular, $(N (γ_{L})-κL^{2})/L^{3/2}$ converges weakly to a Gaussian distribution. Similar results are proved for generic geodesics, that is, geodesics whose initial tangent vectors are chosen randomly according to normalized Liouville measure.

description: We show that the resonant coupling of phonons and magnons can be exploited to generate spin currents at room temperature. Surface acoustic wave (SAW) pulses with a frequency of 1.55 GHz and duration of 300 ns provide coherent elastic waves in a ferromagnetic thin film/normal metal (Co/Pt) bilayer. We use the inverse spin Hall voltage in the Pt as a measure for the spin current and record its evolution as a function of time and external magnetic field magnitude and orientation. Our experiments show that a spin current is generated in the exclusive presence of a resonant elastic excitation. This establishes acoustic spin pumping as a resonant analogue to the spin Seebeck effect.

description: We propose a new theory of gravitation, in which the affine connection is the only dynamical variable describing the gravitational field. We construct the simplest dynamical Lagrangian density that is entirely composed from the connection, via its curvature and torsion, and is an algebraic function of its derivatives. It is given by the contraction of the Ricci tensor with a tensor which is inverse to the symmetric, contracted square of the torsion tensor, $k_{μν}=S^ρ_{λμ}S^λ_{ρν}$. We vary the total action for the gravitational field and matter with respect to the affine connection, assuming that the matter fields couple to the connection only through $k_{μν}$. We derive the resulting field equations and show that they are identical with the Einstein equations of general relativity with a nonzero cosmological constant, if the tensor $k_{μν}$ is regarded as the metric tensor. The cosmological constant is simply a constant of proportionality between the two tensors, which together with $c$ and $G$ provides a natural system of units in gravitational physics. This theory therefore provides a physically valid construction of the metric as an algebraic function of the connection, and naturally explains dark energy as an intrinsic property of spacetime. The observed accelerating expansion of the Universe may be the strongest evidence for torsion.

description: Leopardus is a genus that, despite currently being widely distributed in South America, shows until now a fragmentary fossil record. Among Leopardus, L. pardalis is the largest species, having an historical range that includes tropical and subtropical habitats from southern U.S.A. to southern South America but, as usual in the ocelot lineage, fossil remains that can be interpreted with certainty are restricted to the Late Pleistocene of southern U.S.A. and Brazil. Here we present a new record (a fragment of right maxillary plus zygomatic with P4–M1; incomplete left mandible with the coronoid process, part of c1 alveolus and p3–m1; isolated right c1) from the Late Pleistocene of Arroyo Toropí, Corrientes province, Argentina. The bearing level was dated with Optically Stimulated Luminescence (OSL) to 98.4 ka (Marine Isotopic Stage, MIS 5c). Present environmental requirements of L. pardalis and climatic reconstructions carried out here suggest a compatible scenario with MIS 5 for this fossil, which is concordant with the associated dating (ca. 98.4 ka). Leopardus pardalis appears to be part of a subtropical fauna, with Tayassu pecari and Euphractus sexcinctus, which inhabited the region during warm and wet climatic events of MIS 5c. Phytoliths and other vertebrates are congruent with its presence, since the inferred conditions are similar to the present one. The new record is relevant not only because it is the first fossil record of the species for the Pleistocene of Argentina, but also because it is placed 1800 km south of the closest accurately identified published fossil.

description: Questo libro ha vinto il “Premio Tesi di Dottorato 2023” istituito da Sapienza Università Editrice.
Nelle Genealogiae deorum gentilium XIV 7 Boccaccio afferma: «grammatica precepta atque rethorice plena notitia oportuna est». In età ormai matura, dichiara che nella formazione di un uomo di lettere la conoscenza della grammatica e della retorica è un elemento necessario. Rhetorica eloquentia armat sonda il peso delle strutture retoriche nella prosa narrativa boccacciana. Scegliendo di interrogare l’istanza formale delle opere dal Filocolo al De casibus, ne sono indagati i significati più profondi, nonché il rapporto che intercorre tra ars bene dicendi e ars bene vivendi. L’amplificatio e l’evidentia rappresentano una chiave per l’esame della scrittura e del pensiero di Boccaccio, che apre la strada a un più completo ragionamento sui contenuti etici, morali e filosofici della sua produzione.
Error detection for soft computing applications
Creators: name: Thomas, Anna
Publisher: name: University of British Columbia
Year: 2013

description: Hardware errors are on the rise with reducing chip sizes, and power constraints have necessitated the involvement of software in hardware error detection. At the same time, emerging workloads in the form of soft computing applications, (e.g., multimedia applications) can tolerate most hardware errors as long as the erroneous outputs do not deviate significantly from error-free outcomes. We term outcomes that deviate significantly from the error-free outcomes as Egregious Data Corruptions (EDCs). In this thesis, we propose a technique to place detectors for selectively detecting EDC causing errors in an application. Our technique identifies program locations for placing high coverage detectors for EDCs using static analysis and runtime profiling. We evaluate our technique on six benchmarks to measure the EDC coverage under given performance overhead bounds. Our technique achieves an average EDC coverage of 82%, under performance overheads of 10%, while detecting only 10% of the Non-EDC and benign faults. We also explore the performance-resilience tradeoff space, by studying the effect of compiler optimizations on the error resilience of soft computing applications, both with and without our technique.

description: I present a construction of connected affine algebraic supergroups G_V associated with simple Lie superalgebras g of Cartan type and with g-modules V. Conversely, I prove that every connected affine algebraic supergroup whose tangent Lie superalgebra is of Cartan type is necessarily isomorphic to one of the supergroups G_V that I introduced. In particular, the supergroup constructed in this way associated with g := W(n) and its standard representation is described somewhat more in detail. In addition, *** an "Erratum" is added here *** after the main text to fix a mistake which was kindly pointed out to the author by prof. Masuoka after the paper was published: this "Erratum" is accepted for publication in "Forum Mathematicum", it appears here in its final form (but prior to proofreading). In it, I also explain more in detail the *Existence Theorem* for algebraic supergroups of Cartan type which comes out of the main result in the original paper.

"Can you leave the light on? I'm afraid of the dark." : feminist criticism and the life writing of Virginia Woolf and Gloria Anzaldúa
Creators: name: Coulson, Marcella Meghan
Publisher: name: University of British Columbia
Year: 2013

description: This project works with Virginia Woolf’s Moments of Being and Gloria Anzaldúa’s Borderlands: La Frontera to suggest that the problem of representing material feminisms in relational women’s life writing is located in white feminists’ desire to remain at home in their criticism. Bringing feminist theories on materiality, politics of belonging and affect together, I reflect on the ways my white privilege permits my criticism to haunt the very subjects whom it suggests I am writing for. In doing so, I demonstrate the ways feminism can be used by white feminists to protect the authority of white feminist criticism, and thus reinforce the white feminist’s privileged position as the subject of feminism. In this way, marking whiteness works to maintain white women’s privilege in feminism, rather than disturb their constructions of identity as feminists. I work with Gloria Anzaldúa’s borderland theory to work through this problem by reflecting on my experiences of being in other women’s criticism. This enables me to work through affective, yet material boundaries between the white feminist self and other feminists. I argue that silence about the affective experiences of the contradictions that characterize white privilege for feminists permits white feminists to lean on the comforts of their knowledge of feminism, and to refuse to acknowledge other women’s writings as criticism.

description: Here, we report new dental remains of a large giraffid from the Late Miocene of Pakistan. The new material improves our knowledge of the dental morphology of this extinct sivatherine giraffid, as it sheds light on intra-clade morphological variability within Late Miocene sivatherine giraffids. Fossils were recovered from sediments within the Nagri and Dhok Pathan formations (Middle Siwaliks, Late Miocene) from the sites Nagri, Dhok Pathan, Kauliar and Padhri in Pakistan. Presence of these fossils in Late Miocene sediments in Pakistan demonstrates the stratigraphic range of Bramatherium grande, which was present in the Indo-Pakistani region and the Greco-Iranian region from 11.2 to ca. 3.4 Ma and 11.2 to 9.0 Ma, respectively. The new fossils provide additional data that help resolve the phylogenetic relationships of these large Late Miocene sivatheres. The new findings highlight the presence of Bramatherium grande in the Indo-Pakistani region during the Late Miocene and provide evidence for the synonymy of Bramatherium grande and Bramatherium magnum, with Bramatherium grande having priority.

Using extensive Keck LRIS/DEIMOS spectroscopy in conjunction with ten-band ground-based, Spitzer, and HST imaging, we investigate the buildup of the red sequence in groups and clusters at high redshift. Nearly all of the brightest and most massive red-sequence galaxies are found within the bounds of the clusters and groups. Despite the prevalence of these red-sequence galaxies, we find that the average cluster galaxy has a spectrum indicative of a star-forming galaxy, with a star formation rate between those of z~1 field galaxies and moderate redshift cluster galaxies. The average group galaxy is even more active, exhibiting properties indicative of a starburst. The presence of massive, red galaxies and the high fraction of starbursting galaxies suggest that significant processing is occurring in the group environment at z~1 and earlier. There is a deficit of low-luminosity red-sequence galaxies in all Cl1604 clusters and groups, suggesting that such galaxies transition to the red sequence at later times. Extremely massive (10^12) red sequence galaxies are also absent from the Cl1604 clusters and groups. We suggest that such galaxies form at later times through merging processes. There are also large populations of transition galaxies at intermediate stellar masses present in the groups and clusters, suggesting that such masses are important in the buildup of the red-sequence mass function at z~1. Through a comparison of the transitional populations present in the Cl1604 clusters and groups, we find evidence that massive blue cloud galaxies are quenched earliest in the most dynamically relaxed systems and at progressively later times in dynamically unrelaxed systems.

description: The first known primate fossil from the Atlantic Coastal Plain, a mandibular fragment representing the family Omomyidae, is described from the early Eocene Fisher/Sullivan Site in northeastern Virginia. The jaw, containing m1–m2, was found near the base of the Potapaco Member, Bed B, of the Nanjemoy Formation, indicating an early Ypresian age, ca. 54.5 Ma. As the specimen lacks diagnostic antemolar dentition, its precise identity cannot be confidently determined. However, its diminutive size and plesiomorphic molar morphology suggest that it represents a primitive omomyid. Comparison with a diversity of omomyids finds that nearly all omomyid genera are larger and/or derived in various features compared to the Nanjemoy specimen. Closest resemblances are to the primitive omomyids Steinius, Anemorhysis, Loveina, Melaneremia, and especially Teilhardina.
A Variable Partial Covering Model for the Seyfert 1 Galaxy MCG-6-30-15

description: We propose a simple spectral model for the Seyfert 1 Galaxy MCG-6-30-15 that can explain most of the 1 - 40 keV spectral variation by change of the partial covering fraction, similar to the one proposed by Miller et al. (2008). Our spectral model is composed of three continuum components; (1) a direct power-law component, (2) a heavily absorbed power-law component by mildly ionized intervening matter, and (3) a cold disk reflection component far from the black hole with moderate solid-angle (Ω/2π \approx 0.3) accompanying a narrow fluorescent iron line. The first two components are affected by the surrounding highly ionized thin absorber with N_H \approx 10^{23.4}cm-2 and log ξ \approx 3.4. The heavy absorber in the second component is fragmented into many clouds, each of which is composed of radial zones with different ionization states and column densities, the main body (N_H \approx 10^24.2cm-2, log ξ \approx 1.6), the envelope (N_H \approx 10^22.1cm-2, log ξ \approx 1.9) and presumably a completely opaque core. These parameters of the ionized absorbers, as well as the intrinsic spectral shape of the X-ray source, are unchanged at all. The central X-ray source is moderately extended, and its luminosity is not significantly variable. The observed flux and spectral variations are mostly explained by variation of the geometrical partial covering fraction of the central source from 0 (uncovered) to \sim0.63 by the intervening ionized clouds in the line of sight. The ionized iron K-edge of the heavily absorbed component explains most of the seemingly broad line-like feature, a well-known spectral characteristic of MCG-6-30-15. The direct component and the absorbed component anti-correlate, cancelling their variations each other, so that the fractional spectral variation becomes the minimum at the iron energy band; another observational characteristic of MCG-6-30-15 is thus explained.

New insights into the Be/X-ray binary system MXB 0656-072

description: The X-ray transient MXB 0656-072 is a poorly studied member of high-mass X-ray binaries. Based on the transient nature of the X-ray emission, the detection of pulsations, and the early-type companion, it has been classified as a Be X-ray binary (Be/XRB). However, the flaring activity covering a large fraction of a giant outburst is somehow peculiar. Our goal is to investigate the multiwavelength variability of the high-mass X-ray binary MXB 0656-072. We carried out optical spectroscopy and analysed all RXTE archive data, performing a detailed X-ray-colour, spectral, and timing analysis of both normal (type-I) and giant (type-II) outbursts from MXB 0656-072 This is the first detailed analysis of the optical counterpart in the classification region (4000-5000 A). From the strength and ratio of the elements and ions, we derive an O9.5Ve spectral type, in agreement with previous classification. This confirms its Be nature. The characterisation of the Be/XRB system relies on Balmer lines in emission in the optical spectra, long-term X-ray variability, and the orbital period vs. spin period and EW(Hα) relation. The peculiar feature that distinguishes the type-II outburst is flaring activity, which occurs during the whole outburst peak, before a smoother decay. We interpret it in terms of magneto-hydrodynamic instability. Colour and spectral analysis reveal a hardening of the spectrum as the flux increases. We explored the aperiodic X-ray variability of the system for the first time, finding a correlation of the central frequency and rms of the main timing component with luminosity, which extends up to a "saturation" flux of 1E-8 erg/cm^2/s. A correlation between timing and spectral parameters was also found, pointing to an interconnection between the two physical regions responsible for both phenomenologies.

description: Here we report a new cricetid s.l., Caecocricetodon yani, gen. et sp. nov., discovered in the early Oligocene of the Caijiachong Formation in Yunnan Province, China. The new cricetid differs from all known cricetids or stem muroids by its particular molar pattern displaying numerous crests and spurs. Our phylogenetic analysis based on a matrix including 42 taxa and 72 characters indicates that the new species has a close relationship with Paracricetodontinae, forming a monophyletic clade with Paracricetodon and Trakymys. The new cricetid also has a likely close relationship with Pappocricetodon. However, the genus Pappocricetodon is polyphyletic in our analysis. Considering the similarity of the brachydont lophodont teeth of Caecocricetodon and glirids, we propose that the new species underwent convergent evolution with dormice, possibly adapting to an arboreal ecological niche in Oligocene of southern China.

description: In this paper we present an algorithm for rapid Bayesian analysis that combines the benefits of nested sampling and artificial neural networks. The blind accelerated multimodal Bayesian inference (BAMBI) algorithm implements the MultiNest package for nested sampling as well as the training of an artificial neural network (NN) to learn the likelihood function. In the case of computationally expensive likelihoods, this allows the substitution of a much more rapid approximation in order to increase significantly the speed of the analysis. We begin by demonstrating, with a few toy examples, the ability of a NN to learn complicated likelihood surfaces. BAMBI's ability to decrease running time for Bayesian inference is then demonstrated in the context of estimating cosmological parameters from Wilkinson Microwave Anisotropy Probe and other observations. We show that valuable speed increases are achieved in addition to obtaining NNs trained on the likelihood functions for the different model and data combinations. These NNs can then be used for an even faster follow-up analysis using the same likelihood and different priors. This is a fully general algorithm that can be applied, without any pre-processing, to other problems with computationally expensive likelihood functions.

description: Η ιστορία της επιστήμης της λογικής ανάγεται πολλούς αιώνες πίσω, στην εποχή του Αριστοτέλη, ο οποίος υπήρξε και θεμελιωτής της. Τους δύο τελευταίους αιώνες η εξέλιξη της ήταν ραγδαία και πλέον αποτελεί απαραίτητο στοιχείο σε όλες τις επιστήμες. Από τα τέλη του 19ου αιώνα, η μαθηματική λογική ανέκυψε ως φυσικό επακόλουθο της ανάγκης κατασκευής μιας αυστηρής γλώσσας για την περιγραφή περίπλοκων μαθηματικών θεωριών. Η μαθηματική λογική συναντάται και ως τυπική λογική, λόγω του αυστηρού χαρακτήρα της και συμβολική, λόγω των συμβόλων που χρησιμοποιεί αντί για λέξεις. Τα δύο σημαντικότερα είδη μαθηματικής λογικής είναι ο προτασιακός λογισμός και ο κατηγορηματικός λογισμός. Στην παρούσα εργασία περιγράφουμε τη γλώσσα του κατηγορηματικού λογισμού και πιο συγκεκριμένα το συντακτικό, τη σημασιολογία και τους μηχανισμούς εξαγωγής συμπερασμάτων της. Στη συνέχεια επιχειρείται η μετατροπή προτάσεων φυσικής γλώσσας στην τυπική γλώσσα του κατηγορηματικού λογισμού. Πιο συγκεκριμένα, οι προτάσεις φυσικής γλώσσας που θα μεταγραφούν στη κατηγορηματική γλώσσα έχουν προέλθει από τους φιλοσοφικούς διαλόγους του Πλάτωνα. Σε αυτά τα έργα γίνεται μια προσπάθεια ορισμού μιας έννοιας, όπου από διάφορες προκείμενες προτάσεις καταλήγουν σε ένα συμπέρασμα. Τέλος, με το βασικό μηχανισμό εξαγωγής συμπερασμάτων της κατηγορηματικής λογικής, θα ελέγξουμε την ορθότητα αυτών των συμπερασμάτων.

description: We classify the connected Lie subgroups of the symplectic group $Sp(2,\mathbb{R})$ whose elements are matrices in block lower triangular form. The classification is up to conjugation within $Sp(2,\mathbb{R})$. Their study is motivated by the need of a unified approach to continuous 2D signal analyses, as those provided by wavelets and shearlets.
