description: Construction spaces are constantly evolving, dynamic environments in need of continuous surveying, inspection, and assessment. Traditional manual inspection of such spaces proves to be an arduous and time-consuming activity. Automation using robotic agents can be an effective solution. Robots, with perception capabilities can autonomously classify and survey indoor construction spaces. In this paper, we present a novel identification-on-the-fly approach for coarse classification of indoor spaces using the unique signature of clutter. Using the context granted by clutter, we recognize common indoor spaces such as corridors, staircases, shared spaces, and restrooms. The proposed clutter slices pipeline achieves a maximum accuracy of 93.6% on the presented clutter slices dataset. This sensor independent approach can be generalized to various domains to equip intelligent autonomous agents in better perceiving their environment.

description: Σκοπός της παρούσας εργασίας είναι να εντοπίσει τη διαφορετική προσέγγιση που παρουσιάζουν τα δύο φύλα κατά την παρακολούθηση σεξιστικών χιουμοριστικών διαφημίσεων. Η διαφορετική αυτή προσέγγιση θα εξεταστεί με μία μη λεκτική μέθοδο ελέγχου, με τη χρήση του Ηλεκτροεγκεφαλογραφήματος (EEG). Για τις ανάγκες της μελέτης πραγματοποιήθηκε πείραμα με τη συνεργασία των επιστημών της Διαφήμισης και της Νευροεπιστήμης, έχοντας ως σημείο αναφοράς τη σεξιστική προσέγγιση, μέσα από τη διαφήμιση. Αναλύοντας τα αποτελέσματα του πειράματος, παρατηρήθηκε ότι στα εγκεφαλικά κύματα του δέκτη ενός σεξιστικού χιουμοριστικού μηνύματος καταγράφηκαν ποικίλες αντιδράσεις, που χρήζουν περαιτέρω στατιστικής ανάλυσης και μελέτης. Η συνεισφορά της εργασίας αυτής είναι ότι αναπτύσσει το πλαίσιο που ενδείκνυται προς μελέτη από τις επιστήμες της Διαφήμισης και της Νευροεπιστήμης. Επίσης, αποδεικνύει την ύπαρξη σημαντικών στοιχείων, τα οποία χρήζουν μελέτης, ώστε σε μελλοντική έρευνα να διερευνηθεί περαιτέρω ο τρόπος που αποκωδικοποιούνται τα σεξιστικά χιουμοριστικά ερεθίσματα από τον ανθρώπινο εγκέφαλο.
description: The purpose of this study is to identify the different approaches of the two Sexes, while watching sexist humorous advertisements. This different approach will be addressed through non-verbal methods of testing, using the Electroencephalogram (EEG). To achieve this study, an experiment was performed with the collaboration of science of Advertising and Neuroscience, where the experiment had the content of the sexist approach through advertising. The analysis reveals that there is statistical significance in brain waves of a receiver of sexist humorous message. The contribution of this work is to develop the appropriate framework to study the collaboration of Advertising and Neuroscience. It also demonstrates the existence of significant elements that should be addressed and will reveal in future research the way that sexist humorous stimuli are decoded in the human brain.

Detonating Failed Deflagration Model of Thermonuclear Supernovae I. Explosion Dynamics
Creators: name: Plewa, Tomasz
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a detonating failed deflagration model of Type Ia supernovae. In this model, the thermonuclear explosion of a massive white dwarf follows an off-center deflagration. We conduct a survey of asymmetric ignition configurations initiated at various distances from the stellar center. In all cases studied, we find that only a small amount of stellar fuel is consumed during deflagration phase, no explosion is obtained, and the released energy is mostly wasted on expanding the progenitor. Products of the failed deflagration quickly reach the stellar surface, polluting and strongly disturbing it. These disturbances eventually evolve into small and isolated shock-dominated regions which are rich in fuel. We consider these regions as seeds capable of forming self-sustained detonations that, ultimately, result in the thermonuclear supernova explosion. Preliminary nucleosynthesis results indicate the model supernova ejecta are typically composed of about 0.1-0.25 Msun of silicon group elements, 0.9-1.2 Msun of iron group elements, and are essentially carbon-free. The ejecta have a composite morphology, are chemically stratified, and display a modest amount of intrinsic asymmetry. The innermost layers are slightly egg-shaped with the axis ratio ~1.2-1.3 and dominated by the products of silicon burning. This central region is surrounded by a shell of silicon-group elements. The outermost layers of ejecta are highly inhomogeneous and contain products of incomplete oxygen burning with only small admixture of unburned stellar material. The explosion energies are ~1.3-1.5 10^51 erg.

description: With the advancement of the Internet of Things (IoT) and communication platform, large scale sensor deployment can be easily implemented in an urban city to collect various information. To date, there are only a handful of research studies about understanding the usage of urban public spaces. Leveraging IoT, various sensors have been deployed in an urban residential area to monitor and study public space utilization patterns. In this paper, we propose a data processing system to generate space-centric insights about the utilization of an urban residential region of multiple points of interest (PoIs) that consists of 190,000m$^2$ real estate. We identify the activeness of each PoI based on the spectral clustering, and then study their corresponding static features, which are composed of transportation, commercial facilities, population density, along with other characteristics. Through the heuristic features inferring, the residential density and commercial facilities are the most significant factors affecting public place utilization.

Ludwig Wittgenstein on Rationalism

Publisher: name: University of Notre Dame
Year: 2024

description: If “rationalism” refers to the thesis that there is a right way to do whatever it is that we do—a way that we, with our reason, can discover—then Ludwig Wittgenstein is a critic of rationalism. For our words and deeds are justified only by the rules of particular language-games—but these language-games are themselves justified only insofar as they meet our needs; certainly none of them need be justified by reference to any of the others. Together, our language-games constitute our form of life; though this form of life is not entirely arbitrary—some of its features can be explained by reference to our nature—nonetheless, it could be different in many ways. Indeed, it *has* been—and therefore probably *will* be—different in many ways; on some level, we all know this. Philosophy at its worst is the attempt to forget it; philosophy at its best is, therefore, the attempt to remember it.

description: Earthquakes and solar flares are phenomena involving huge and rapid releases of energy characterized by complex temporal occurrence. By analysing available experimental catalogs, we show that the stochastic processes underlying these apparently different phenomena have universal properties. Namely both problems exhibit the same distributions of sizes, inter-occurrence times and the same temporal clustering: we find afterflare sequences with power law temporal correlations as the Omori law for seismic sequences. The observed universality suggests a common approach to the interpretation of both phenomena in terms of the same driving physical mechanism.
A professional development model based on interrelated principles of teacher learning
Creators: name: Hoban, Garry
Publisher: name: University of British Columbia
Year: 2009

description: This study explored the value of a professional development model and identified issues to be considered when using the model in a secondary school setting. The design of the model was based on three interrelated principles to support teachers in: (a) developing an awareness of their beliefs, (b) considering alternative perspectives from colleagues and their own students, and (c) generating a community learning environment to promote interplay between the principles of awareness and alternatives. This model guided the organization of a professional development program for three secondary science teachers over a period of two and a half years. Two research questions were addressed in the study: (l) How did the teachers understand their practice and in what ways did their understanding change as a result of the professional development program? and (2) What features of the professional development program influenced change in the teachers' understanding of their practice? As a result of the program there was a substantial change in how the teachers understood their practice. The teachers identified five common features of the program that enhanced this change: (a) personal reflections, (b) student tapes, (c) group discussions, (d) experimenting with their practice, and (e) feedback on their ideas. These features were consistent with the above three principles and were represented in models of their own learning, but not in the same configuration as in the proposed professional development model. - Two strengths of the professional development model are., evident from the study. First, the model provides an organizational framework to support teachers in sustained knowledge-building within their community. Second, the model is underpinned by a theoretical basis for teacher learning relating individual and social influences on knowledge construction. This basis is consistent with a social constructivist perspective on learning and with Dewey's (1938) theory of learning through experience. Issues to consider when using the model center on the ethical concerns of students disclosing information about their learning experiences and the need for collegiality to encourage teachers to share ideas. The main implication of the study is that organizers of professional development programs should not only consider each principle of teacher learning, but the interrelationship between them to provide teachers with opportunities for sustained knowledge-building.

description: We report the abundance analysis of one red giant branch star in the metal-poor outer halo globular cluster NGC 5694. We obtain [Fe/H] = -1.93, based on the ionized lines, and our metallicity measurement is in good agreement with previous estimates. We find that [Ca+Ti/2Fe] and [Cu/Fe] of NGC 5694 are about 0.3 -- 0.4 dex lower than other globular clusters with similar metallicities, but similar to some LMC clusters and stars in some dwarf spheroidal galaxies. Differences persist, however, in the abundances of neutron capture elements. The unique chemical abundance pattern and the large Galactocentric distance (30 kpc) and radial velocity (-138.6 +/- 1.0 km/sec) indicate that NGC 5694 had an extragalactic origin.

description: Within the postgraduate program of the Geology Department, I was assigned the following thesis topic : “ Laboratory and in situ tests to determine the hydraulic conductivity in the unsaturated zone in the Anthemountas basin”. Firstly, I refer to the geological, geomorphological and hydrological characteristics of the area. Secondly, the ratio of the hydraulic conductivity is defined and how to identify it. Also, I mention the methods by which the ratio of the hydraulic conductivity is calculated either in the laboratory or outdoors. Then, by using the method of screening, the 20 samples taken from the basin of Anthemounta were classified and then characterized by the coefficient of the hydraulic conductivity. As a result, some conclusions on the permeability of the studied area were made and consequently, the coefficient of the hydraulic conductivity.

description: This work proposes an unsupervised fusion framework based on deep convolutional transform learning. The great learning ability of convolutional filters for data analysis is well acknowledged. The success of convolutive features owes to convolutional neural network (CNN). However, CNN cannot perform learning tasks in an unsupervised fashion. In a recent work, we show that such shortcoming can be addressed by adopting a convolutional transform learning (CTL) approach, where convolutional filters are learnt in an unsupervised fashion. The present paper aims at (i) proposing a deep version of CTL; (ii) proposing an unsupervised fusion formulation taking advantage of the proposed deep CTL representation; (iii) developing a mathematically sounded optimization strategy for performing the learning task. We apply the proposed technique, named DeConFuse, on the problem of stock forecasting and trading. Comparison with state-of-the-art methods (based on CNN and long short-term memory network) shows the superiority of our method for performing a reliable feature extraction.

description: This study focuses on mixed-variable black-box optimization (MV-BBO), addressing continuous, integer, and categorical variables. Many real-world MV-BBO problems involve dependencies among these different types of variables, requiring efficient methods to optimize them simultaneously. Recently, stochastic optimization methods leveraging the mechanism of the covariance matrix adaptation evolution strategy have shown promising results in mixed-integer or mixed-category optimization. However, such methods cannot handle the three types of variables simultaneously. In this study, we propose CatCMA with Margin (CatCMAwM), a stochastic optimization method for MV-BBO that jointly optimizes continuous, integer, and categorical variables. CatCMAwM is developed by incorporating a novel integer handling into CatCMA, a mixed-category black-box optimization method employing a joint distribution of multivariate Gaussian and categorical distributions. The proposed integer handling is carefully designed by reviewing existing integer handlings and following the design principles of CatCMA. Even when applied to mixed-integer problems, it stabilizes the marginal probability and improves the convergence performance of continuous variables. Numerical experiments show that CatCMAwM effectively handles the three types of variables, outperforming state-of-the-art Bayesian optimization methods and baselines that simply incorporate existing integer handlings into CatCMA.

description: Schizophyllum amplum (Agaricales, Schizophyllaceae) is reported for the first time in Malta and Estonia. The collections from Malta were examined morphologically and compared with previously published accounts of this species. The specimens from Estonia and Malta were sequence d after PCR amplification with ITS1F and ITS4 for ITS region. The sequences were then compared to other sequences deposited in public databases using BLASTn. Genetically the ITS rDNA data obtained from the Maltese and Estonian specimens are 99% similar but show some differences from other sequences of S. amplum (L43381 and L43382) deposited in GenBank. A multigenetic approach with a larger number of specimens should be employed to define the currently accepted genetic limits for Schizophyllum species.

description: Cancer cells reprogram metabolism to support rapid proliferation and survival. Energy metabolism is particularly important for growth. A genome scale metabolic model (GSMM) is a mathematical formalization of metabolism which allows simulation and hypotheses testing of metabolic strategies using Constraint-Based Modeling. One of the widely used generic human metabolic models is Recon 2.2, containing 7785 reactions, 5324 metabolites and 1675 genes. The accuracy of predictions using GSMMs is dependent on accurate gene associations to reactions. Current GSMMs do not consider intracellular protein localization in annotating GPR relationships which may lead to false positives.
In this study, protein localization data obtained from 10 different studies were used to verify the intracellular location of each protein. Mismatches between protein localization and reaction location were corrected. The modified RECON 2.2 (RECON 2.4) includes 8133 reactions, 5799 metabolites and 1758 genes, an increase of 5%, 10% and 5% in size, respectively.
The improved model can better predict essential genes. Essential genes were tested by comparing to previously published CRISPR screens.

description: Breast density, which is the ratio between fibroglandular tissue (FGT) and total breast volume, can be assessed qualitatively by radiologists and quantitatively by computer algorithms. These algorithms often rely on segmentation of breast and FGT volume. In this study, we propose a method to directly assess breast density on MRI, and provide interpretations of these assessments. We assessed breast density in 506 patients with breast cancer using a regression convolutional neural network (CNN). The input for the CNN were slices of breast MRI of 128 x 128 voxels, and the output was a continuous density value between 0 (fatty breast) and 1 (dense breast). We used 350 patients to train the CNN, 75 for validation, and 81 for independent testing. We investigated why the CNN came to its predicted density using Deep SHapley Additive exPlanations (SHAP). The density predicted by the CNN on the testing set was significantly correlated with the ground truth densities (N = 81 patients, Spearman's rho = 0.86, P < 0.001). When inspecting what the CNN based its predictions on, we found that voxels in FGT commonly had positive SHAP-values, voxels in fatty tissue commonly had negative SHAP-values, and voxels in non-breast tissue commonly had SHAP-values near zero. This means that the prediction of density is based on the structures we expect it to be based on, namely FGT and fatty tissue. To conclude, we presented an interpretable deep learning regression method for breast density estimation on MRI with promising results.

The Politics of Place: How Southern Identity Shapes Americans' Political Beliefs

Subjects: subject: South, public opinion, race, identity

description: ABSTRACT This dissertation investigates the role of place-based identification in influencing Americans’ political attitudes and policy preferences. Specifically, I argue that Southern identity (i.e., identification with the American South) is an influential but omitted factor that affects American public opinion and political behavior. This dissertation includes three overarching arguments. First, the South residency variables and other inconsistent identity measurements are insufficient in helping us understand how and why sub-national identifications shape American public opinion and behavior. A new sub-national identity framework and survey measurement are needed to understand the values and norms people associate with social groups to understand how social identities translate into political beliefs. Second, this work argues that Southern identity has political consequences for Black Americans and White Americans. Finally, I contend that Southern identity is associated with beliefs that reflect theSouth’s perceived communal, traditional, and hierarchical culture elements. The primary contribution of this dissertation is the creation of a novel multidimensional scale of Southern identity that was motivated and constructed from analysis of a variety of South-related qualitative data. Em-ploying the Southern identity scale, I assess its affect on Americans’ views about various race, social, and economic-related political issues, and public policies. Analyses from three original surveys suggest that Southern identity is, in fact, associated with distinct and nuanced political beliefs for both Black and White Americans. Specifically, Southern identity is associated with more group-centric and communalistic attitudes for Black and White Americans. Regarding social issues, Southern identity is associated with more conservative, hierarchical, and tradi-tional attitudes across racial groups. With respect to economic policies, Southern identity is associated with communalistic and group centric attitudes as well. These results hint at a chal-lenge to the claim that Southern identity among Black Americans is not as politically relevant as it is for White Americans. This work also speaks to the need for more nuanced approaches to understanding American’s political beliefs across race and place. xvi

description: Στον εμπορικό κόσμο και στη σημερινή εποχή πρωταρχικός στόχος από τη σύλληψη ακόμη της ίδρυσης μίας εταιρείας είναι το κέρδος. Το μάρκετινγκ είναι η επιστήμη που έχει επιφορτισθεί με το ρόλο της προσέλκυσης δυνητικών πελατών, αύξησης του πελατολογίου και κατ’ επέκταση εκτόξευση των κερδών. Πώς όμως τροφοδοτείται το σύστημα αυτό με τις κατάλληλες πληροφορίες οι οποίες θα βεβαιώσουν την αδιάλειπτη επιτυχημένη λειτουργία του; Πώς συλλέγονται, αξιοποιούνται και μετατρέπονται σε αξιοποιήσιμες πληροφορίες τα δεδομένα που άπλετα υπάρχουν στον επιχειρηματικό κόσμο; Την απάντηση στα παραπάνω ερωτήματα καλείται να δώσει η επιστήμη της εξόρυξης των δεδομένων μέσω των ισχυρότατων εργαλείων και μεθόδων που διαθέτει. Η παρούσα εργασία έρχεται να παρουσιάσει, να επιβεβαιώσει και να βελτιώσει περεταίρω αποτελέσματα παλιότερων ερευνών γύρω από τη χρήση των τεχνικών της εξόρυξης δεδομένων πάνω σε επιχειρηματικά δεδομένα και πιο συγκεκριμένα γύρω από την πρόβλεψη διανομής μερίσματος. Η πρόβλεψη διανομής μερίσματος ή όχι είναι ζωτικής σημασίας τόσο για υποψήφιους, όσο και για υπάρχοντες επενδυτές και μετόχους, αφού πρόκειται για ίδιο όφελος.

Primary children’s perceptions of mathematical problem solving

description: This study explores primary children's perceptions of mathematical problem-solving. A review of current literature in this area indicated a need to focus on children's thoughts and ideas. The children's perceptions of what a math problem is, their problem-solving process and their stated use and preference for problem-solving strategies were investigated. For this study, seven grade two students from the researcher's primary classroom were interviewed individually. A set of research questions provided a guide for the researcher during the interviews, but allowed flexibility so that both the subject and the researcher could add questions or information as required. A natural conversational flow was desired. The interviews were transcribed and analyzed. Individual student descriptions as well as comparisons between students in significant areas were prepared. It was found that the children had varied definitions for what a math problem is. Although some children had difficulty articulating a definition, they demonstrated an understanding through their examples. Most of the children stated that a math problem has words and some math and is like a story. A few children also indicated that a math problem could just involve numbers, depending on the level of difficulty. All of the children indicated that they had a problem-solving process in place. This process ranged from "try to figure out the answer and write it down" to a multi-step metacognitive process that involved thinking about the problem, trying different ways to solve it and checking your work. Five of the seven children stated that they included a "looking back" step as part of their problem solving process. This group of children could name several problem-solving strategies and indicated that they each used a variety of strategies for different purposes. The children indicated they preferred the strategies of mental calculations, using a calculator, working with number patterns and asking someone for help. When asked what strategies they use, all the children indicated they used drawings and mental math for some problems. When asked why they used particular strategy, the most common response was because, "they help me." Because the interviews proved viable for this age group and gave the interviewer a wealth of information about the students' thinking, it was suggested that this type of assessment could be applied to classroom use.

description: We present results of a Monte Carlo simulation of the three dimensional Thirring model with the number of fermion flavors N_f varied between 2 and 18. By identifying the lattice coupling at which the chiral condensate peaks, simulations are be performed at couplings g^2(N_f) corresponding to the strong coupling limit of the continuum theory. The chiral symmetry restoring phase transition is studied as N_f is increased, and the critical number of flavors estimated as N_{fc}=6.6(1). The critical exponents measured at the transition do not agree with self-consistent solutions of the Schwinger-Dyson equations; in particular there is no evidence for the transition being of infinite order. Implications for the critical flavor number in QED_3 are briefly discussed.

description: The resonance X(1810) discovered in $J/ψ\to γωϕ$ by BESII is considered as a candidate of $0^{++}$ $Q^2\bar{Q}^2$ state. This model predicts that $X\toωϕ, K^* K^*$ are the two dominant decay channels and $X\to KK, ηη, ηη'$ are suppressed. The cross sections of $γγ\to X\to ωϕ, K^* K^*$ are estimated.

description: The Telescope to Observe Planetary Systems (TOPS) is a proposed space mission to image in the visible (0.4-0.9 micron) planetary systems of nearby stars simultaneously in 16 spectral bands (resolution R~20). For the ~10 most favorable stars, it will have the sensitivity to discover 2 R_E rocky planets within habitable zones and characterize their surfaces or atmospheres through spectrophotometry. Many more massive planets and debris discs will be imaged and characterized for the first time. With a 1.2m visible telescope, the proposed mission achieves its power by exploiting the most efficient and robust coronagraphic and wavefront control techniques. The Phase-Induced Amplitude Apodization (PIAA) coronagraph used by TOPS allows planet detection at 2 lambda/d with nearly 100% throughput and preserves the telescope angular resolution. An efficient focal plane wavefront sensing scheme accurately measures wavefront aberrations which are fed back to the telescope active primary mirror. Fine wavefront control is also performed independently in each of 4 spectral channels, resulting in a system that is robust to wavefront chromaticity.

An Efficient Algorithm for Solving the Phase Field Crystal Model

description: We present and discuss the development of an unconditionally stable algorithm used to solve the evolution equations of the Phase Field Crystal (PFC) model. This algorithm allows for an arbitrarily large algorithmic time step. As the basis for our analysis of the accuracy of this algorithm, we determine an effective time step in Fourier space. We then compare our calculations with a set of representative numerical results, and demonstrate that this algorithm is an effective approach for the study of the PFC models, yielding a time step effectively 180 times larger than the Euler algorithm for a representative set of material parameters. As the PFC model is just a simple example of a wide class of density functional theories, we expect this method will have wide applicability to modeling systems of considerable interest to the materials modeling communities.

description: Based on published data, we have produced a sample of 256 radio sources whose trigonometric parallaxes and proper motions were measured by VLBI. This sample contains Galactic masers associated with massive protostars and stars in active star-forming regions. It also includes young low-mass stars from the Gould Belt region whose radio observations were performed in continuum. Based on this, most complete sample of sources to date, we have estimated the velocities $(U,V,W)_\odot$ and the parameters of the angular velocity of Galactic rotation $Ω_0, Ω^{(1)}_0, ... , Ω^{(4)}_0$ and obtained a new estimate of the distance fromthe Sun to the Galactic center, $R_0=8.15^{+0.04}_{-0.20}$ kpc. The parameters of the Galactic spiral density wave have been found from the series of radial, $V_R$, and residual tangential, $ΔV_{circ}$, velocities of stars. The amplitudes of the radial and tangential velocity perturbations are $f_R=7.0\pm0.9$ km s$^{-1}$ and $f_θ=3.8\pm1.1$ km s$^{-1}$, the perturbation wavelengths are $λ_R=2.3\pm0.2$ kpc and $λ_θ=2.0\pm0.4$ kpc, and the Sun's phases in the spiral density wave are $(χ_\odot)_R=-163^\circ\pm9^\circ$ and $(χ_\odot)_θ=-137^\circ\pm10^\circ$ for the adopted four-armed spiral pattern.

description: We consider quantum communication in the case that the communicating parties not only do not share a reference frame but use imperfect quantum communication channels, in that each channel applies some fixed but unknown unitary rotation to each qubit. We discuss similarities and differences between reference frames within that quantum communication model and gauge fields in gauge theory. We generalize the concept of refbits and analyze various quantum communication protocols within the communication model.

description: The objectives were to develop a novel three-dimensional technology for imaging naturally occurring shear wave (SW) propagation, demonstrate feasibility on human volunteers and quantify SW velocity in different propagation directions. Imaging of natural SWs generated by valve closures has emerged to obtain a direct measurement of cardiac stiffness. Recently, natural SW velocity was assessed in two dimensions on parasternal long axis view under the assumption of a propagation direction along the septum. However, in this approach the source localization and the complex three-dimensional propagation wave path was neglected making the speed estimation unreliable. High volume rate transthoracic acquisitions of the human left ventricle (1100 volume/s) was performed with a 4D ultrafast echocardiographic scanner. Four-dimensional tissue velocity cineloops enabled visualization of aortic and mitral valve closure waves. Energy and time of flight mapping allowed propagation path visualization and source localization, respectively. Velocities were quantified along different directions. Aortic and mitral valve closure SW velocities were assessed for the three volunteers with low standard deviation. Anisotropic propagation was also found suggesting the necessity of using a three-dimensional imaging approach. Different velocities were estimated for the three directions for the aortic (3.4$\pm$0.1 m/s, 3.5$\pm$0.3 m/s, 5.4$\pm$0.7 m/s) and the mitral (2.8$\pm$0.5 m/s, 2.9$\pm$0.3 m/s, 4.6$\pm$0.7 m/s) valve SWs. 4D ultrafast ultrasound alleviates the limitations of 2D ultrafast ultrasound for cardiac SW imaging based on natural SW propagations and enables a comprehensive measurement of cardiac stiffness. This technique could provide stiffness mapping of the left ventricle.
