description: Stripe phases, in which the rotational symmetry of charge density is spontaneously broken, occur in many strongly correlated systems with competing interactions. One representative example is the copper-oxide superconductors, where stripe order is thought to be relevant to the mechanism of high-temperature superconductivity. Identifying and studying the stripe phases in conventional strongly correlated systems are, however, challenging due to the complexity and limited tunability of these materials. Here we uncover stripe phases in WSe2/WS2 moiré superlattices with continuously gate-tunable charge densities by combining optical anisotropy and electronic compressibility measurements. We find strong electronic anisotropy over a large doping range peaked at 1/2 filling of the moiré superlattice. The 1/2-state is incompressible and assigned to a (insulating) stripe crystal phase. It can be continuously melted by thermal fluctuations around 35 K. The domain configuration revealed by wide-field imaging shows a preferential alignment along the high-symmetry axes of the moiré superlattice. Away from 1/2 filling, we observe additional stripe crystals at commensurate filling 1/4, 2/5 and 3/5. The anisotropy also extends into the compressible regime of the system at incommensurate fillings, indicating the presence of electronic liquid crystal states. The observed filling-dependent stripe phases agree with the theoretical phase diagram of the extended Hubbard model on a triangular lattice in the flat band limit. Our results demonstrate that two-dimensional semiconductor moiré superlattices are a highly tunable platform to study the stripe phases and their interplay with other symmetry breaking ground states.

description: In this interview, Courteney Morin and Paul Seesequasis discuss the politics of Indigenous historical photography, repatriation and visual reclamation, and the urgency felt to identify and story ancestor’s memories. Seesequasis provides additional context about the Nelson exhibit Turning the Lens: Indigenous Archive Project, which exemplifies complicated historical experiences of Sinixt and Ktunaxa Nations in the Nelson region. Seesequasis shares how mislabeled and unlabeled photographs in the Nelson Museum Archive spurred discourse around which photos belong to which Nation, thus rendering the forthcoming book Turning the Lens chapter on British Columbia as contentious. Seesequasis’s commitment and passion for representations of visual survivance and authentic community connections is made clear by his patience and support of the process in Nelson and the book. Moreover, his reverence for ancestors in the archival photographs, respect for cultural protocols, and caring methodology is made clear throughout our interview. Seesequasis was a delight to speak with and my hope is that archivists, activists, and academics take note of his steadfast responsibility to community and principled ethic that not everything need digitizing nor does everything in the archive need to be public facing. Cultural and community protocols and governance should be at the forefront of museums and archives’ engagements with Indigenous ancestors and materials. The Nelson Museum, Archives & Gallery is a case study that underscores best practices in territories with complex and layered histories.

Quasinormal modes of plane-symmetric anti-de Sitter black holes: a complete analysis of the gravitational perturbations

description: We study in detail the quasinormal modes of linear gravitational perturbations of plane-symmetric anti-de Sitter black holes. The wave equations are obtained by means of the Newman-Penrose formalism and the Chandrasekhar transformation theory. We show that oscillatory modes decay exponentially with time such that these black holes are stable against gravitational perturbations. Our numerical results show that in the large (small) black hole regime the frequencies of the ordinary quasinormal modes are proportional to the horizon radius $r_{+}$ (wave number $k$). The frequency of the purely damped mode is very close to the algebraically special frequency in the small horizon limit, and goes as $ik^{2}/3r_{+}$ in the opposite limit. This result is confirmed by an analytical method based on the power series expansion of the frequency in terms of the horizon radius. The same procedure applied to the Schwarzschild anti-de Sitter spacetime proves that the purely damped frequency goes as $i(l-1)(l+2)/3r_{+}$, where $l$ is the quantum number characterizing the angular distribution. Finally, we study the limit of high overtones and find that the frequencies become evenly spaced in this regime. The spacing of the frequency per unit horizon radius seems to be a universal quantity, in the sense that it is independent of the wave number, perturbation parity and black hole size.

description: Given the importance of meat consumption, and the proportion of consumers' income spent on meat, this study estimates the demand for eight meat categories using two different functional forms. An inverse almost ideal demand system (IAIDS), and linear double-log price dependent demand models are specified. In most cases, flexibilities obtained from both methods are comparable and show that the demand for meat products is price inflexible. In addition, there are regional as well as seasonal variations in the demand for meat products.

Abelian family symmetries and the simplest models that give theta13=0 in the neutrino mixing matrix
Creators: name: Low, Catherine I.
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: I construct predictive models of neutrino mass and mixing that have fewer parameters, both in the lepton sector and overall, than the default seesaw model. The predictions are theta13=0 and one massless neutrino, with the models having a Z4 or Z2 symmetry and just one extra degree of freedom: one real singlet Higgs field. It has been shown that models with an unbroken family symmetry, and with no Higgs fields other than the Standard Model Higgs doublet produce masses and mixing matrices that have been ruled out by experiment. Therefore, this article investigates the predictions of models with Abelian family symmetries that involve Higgs singlets, doublets and triplets, in the hope that they may produce the maximal and minimal mixing angles seen in the best fit neutrino mixing matrix. I demonstrate that these models can only produce mixing angles that are zero, maximal or unconfined by the symmetry. The maximal mixing angles do not correspond to physical mixing, so an Abelian symmetry can, at best, ensure that theta13=0, while leaving the solar and atmospheric mixing angles as free parameters. To generate more features of the best-fit mixing matrix a model with a non-Abelian symmetry and a complicated Higgs sector would have to be used.

description: We describe the concept of a new gamma ray scintronic detector targeting a time resolution of the order of 25 ps FWHM, with millimetric volume reconstruction and high detection efficiency. Its design consists of a monolithic large PbWO4 scintillating crystal with an efficient photocathode directly deposited on it. With an index of refraction higher for the photocathode than for the crystal, this design negates the total reflection effect of optical photons at the crystal/photo-detector optical interface, and thus largely improves optical coupling between the crystal and the photodetector. This allows to detect efficiently the Cherenkov light produced by 511 keV photoelectric conversions in PbWO4, and to optimize the detector time resolution. Furthermore, the low-yield, fast scintillation light produced additionally by PbWO4 increases the detected photon statistics by a factor 10, thus fostering accurate (3 dimensional) localization of the gamma ray interaction within the crystal and providing a fair measurement of the deposited energy. This paper lists the technological challenges that have to be overcome in order to build this scintronic detector. We show that all the key technologies have now been demonstrated and present results of a preliminary Monte Carlo simulation, which include an innovative event reconstruction algorithm to support the claimed performances of the detector.

description: The presence and behavior of private labels add a significant dimension to price competition among the food system's subsectors. Recent surveys in two college towns in Texas show a larger price difference between national brands and private labels than previous studies. The increase in price differences are attributed to "horizontal" and "vertical" influences on prices and also to advertising and the proliferation of brands. This competitive process gives the consumer the advantage of new products and products with brand appeal (national brands) as well as low cost copies (private labels) of these successful products.
Fiber-optic probe for electro-optic sampling
Creators: name: Chandani, Sameer M.
Publisher: name: University of British Columbia
Year: 2009

description: In-circuit probing of high-speed circuits is becoming a common need as circuit complexity and operating frequencies increase. Electrical methods are not generally capable of probing internal points that are not matched to 50 Ω. Electro-optic sampling is a proven technique for noninvasive in-circuit probing of high-speed circuits, but remains a laboratory tool used by a few experts. This work is aimed at designing and developing a fiber optic based electro-optic sampling system that can be used by test engineers to measure the voltage waveform at internal points. The use of a fiber based pulsed laser and confinement of the optical sampling pulses to fiber optic cables and components results in a compact probe station style system that is easy to use. A novel fiber optic based sampling tip has been designed, built, tested and incorporated into a custom designed microwave probe station. The sampling tip has been made by attaching AlGaAs, an electro-optic material to the end of a fiber optic cable and thinned to a thickness of 1.6 μm using selective wet etching. A theoretical model has been developed to describe the characteristics of the tip when exposed to an external electric field. Measurements of the electric field over a coplanar waveguide structure with 60 μm center and 30 μm gaps have been successfully made. The measurements are consistent with results obtained from an electrostatic simulation of the coplanar waveguide. The electro-optic sampling tip has a V[sub π] of 2200 kV when used as a sensor over the coplanar waveguide at a height of 6 μm above the surface of the conductor. The tip can also be accurately placed over a test point by monitoring the power reflected from the surface of the circuit. A phase locked loop (PLL) has been implemented to synchronize the optical sampling pulses to the signal driving the circuit. The PLL successfully locks the optical pulses and signal driving the circuit to a reference oscillator without degrading the phase noise of the optical sampling pulses.

We consider the most general Seiberg-Witten map which commutes with hermiticity and complex conjugation and a noncommutative matrix parameter, $θ^{μν}$, which is of ``magnetic'' type. Our results for SU(N) can be readily generalized to cover the case of general nonsemisimple gauge groups when the symmetric Seiberg-Witten map is used. Connection with the Atiyah-Singer index theorem is also made.

description: Potato producers in Colorado (and nationwide) have been facing a continued downward trend in potato commodity prices. In an attempt to increase demand for potatoes, these growers had Colorado State University (CSU) researchers perform a market study regarding the viability of marketing a value-added potato. A survey was performed which asked consumers to identify important potato characteristics, their willingness to pay for these characteristics, and what might prompt them to purchase more fresh or processed potatoes in the future. This paper discusses the results and recommendations that CSU made to the Colorado potato producers.

description: We study the information quantities, including the holographic entanglement entropy (HEE), mutual information (MI) and entanglement of purification (EoP), over Gubser-Rocha model. The remarkable property of this model is the zero entropy density at ground state, in term of which we expect to extract novel, even singular informational properties in zero temperature limit. Surprisedly, we do not observe any singular behavior of entanglement-related physical quantities under the zero temperature limit. Nevertheless, we find a peculiar property from Gubser-Rocha model that in low temperature region, the HEE decreases with the increase of temperature, which is contrary to that in most holographic models. We argue that this novel phenomenon is brought by the singular property of the zero temperature limit, of which the analytical verification is present. In addition, we also compare the features of the information quantities in Gubser-Rocha model with those in Reissner-Nordstrom Anti-de Sitter (RN-AdS) black hole model. It is shown that the HEE and MI of Gubser-Rocha model are always larger than those of RN-AdS model, while the EoP behaves in an opposite way. Our results indicate that MI and EoP could have different abilities in describing mixed state entanglement.

The Panel is unique because the unit of analysis is the individual store, and the same stores will be surveyed over time. Linking information on management practices and store and market characteristics with measures for key performance measures provides useful information for both strategic and tactical decisions. Descriptive findings are presented for stores groups by ownership group size and format. Results from a multivariate analysis of relationships between store performance and key performance drivers also are presented.

description: A sample of Louisiana households was surveyed by mail to estimate their degree of support for compulsory country-of-origin labeling of fresh or frozen beef in grocery stores and restaurants. This potential requirement for grocery stores and restaurants was supported by 93 and 88 percent of respondents, respectively. Binomial probit analysis identified the socioeconomic characteristics of consumers with respect to their decision on the labeling of fresh or frozen beef in grocery stores and restaurants. Important variables for both types of outlets were "prefer domestic over imported durable goods," "consider domestic beef safer than imported beef," and "male."

description: It is well-known that direct analytic continuation of DGLAP evolution kernel (splitting functions) from space-like to time-like kinematics breaks down at three loops. We identify the origin of this breakdown as splitting functions are not analytic function of external momenta. However, splitting functions can be constructed from square of (generalized) splitting amplitudes. We establish the rule of analytic continuation for splitting amplitudes, and use them to determine the analytic continuation of certain holomorphic and anti-holomorphic part of splitting functions and transverse-momentum dependent distributions. In this way we derive the time-like splitting functions at three loops without ambiguity. We also propose a reciprocity relation for singlet splitting functions, and provide non-trivial evidence that it holds in QCD at least through three loops.

The data cover the jet transverse momentum range from 61 to 620 GeV/c, extending the reach by almost 150 GeV/c compared with previous measurements at the Tevatron. The results are in good agreement with next-to-leading order perturbative QCD predictions using the CTEQ6.1M parton distribution functions.

description: This reflection begins with the introduction of a Vancouver-centric AI community as a use case to explore what we might learn about the capacity of generative AI to support community building. The inquiry begins an adventure in uncovering previous theory that speaks to the idea that assertions can be made which are specific to a particular place and history. Aligned with situated and place-based knowing, what we discover in breaking apart what makes the Vancouver AI Community Meetup work might inspire those who are considering the development of their own localized communities centered around curiosity toward, integration of, experimentation with, and resistance to public and private generative AI. We propose that at its core, the Vancouver AI community of practice (CoP) demonstrates that building a successful tech community requires a delicate balance of regular engagement, inclusivity, continuous documentation, and social sharing, and a commitment to facilitating formal and informal learning. By embracing these principles, other emerging communities may be able to draw inspiration from Vancouver’s example and cultivate their own vibrant ecosystems of innovation and collaboration.

description: We have obtained HST/STIS far- and near-UV photometry of globular clusters in four fields in the gE galaxy M87. To a limit of m(FUV) = 25 we detect a total of 66 globular clusters (GCs) in common with the deep HST optical-band study of Kundu et al. (1999). Despite strong overlap in V- and I-band properties, the M87 GCs have UV/optical properties that are distinct from clusters in the Milky Way and in M31. M87 clusters, especially metal-poor ones, produce larger hot HB populations than do Milky Way analogues. Cluster mass is probably not a factor in these distinctions. The most metal-rich M87 GCs in our sample are near Z_sun and overlap the local E galaxy sample in estimated Mg_2 line indices. Nonetheless, the clusters produce much more UV light at a given Mg_2, being up to 1 mag bluer than any gE galaxy in (FUV-V) color. The M87 GCs do not appear to represent a transition between Milky Way-type clusters and E galaxies. The differences are in the correct sense if the clusters are significantly older than the E galaxies. Comparisons with Galactic open clusters indicate that the hot stars lie on the extreme horizontal branch, rather than being blue stragglers, and that the EHB becomes well populated for ages > 5 Gyr. We find that 43 of our UV detections have no optical-band counterparts. Most appear to be UV-bright background galaxies, seen through M87. Eleven NUV variable sources detected at only one epoch in the central field are probably classical novae. [Abridged]

description: In order to combine silicon technology with the functionality of magnetic systems, a number of ferromagnetic (FM) materials have been suggested for the fabrication of metal/semiconductor heterojunctions. In this work, we present a systematic study of several candidate materials in contact with the Si surface. We employ density-functional theory calculations to address the thermodynamic stability and magnetism of both pseudomorphic CsCl-like $M$Si ($M$=Mn, Fe, Co, Ni) thin films and Heusler alloy $M_2$MnSi ($M$=Fe, Co, Ni) films on Si(001). Our calculations show that Si-termination of the $M$Si films is energetically preferable during epitaxy since it minimizes the energetic cost of broken bonds at the surface. Moreover, we can explain the calculated trends in thermodynamic stability of the $M$Si thin films in terms of the $M$-Si bond-strength and the $M$ 3d orbital occupation. From our calculations, we predict that ultrathin MnSi films are FM with sizable spin magnetic moments at the Mn atoms, while FeSi and NiSi films are nonmagnetic. However, CoSi films display itinerant ferromagnetism. For the $M_2$MnSi films with Heusler-type structure, the MnSi termination is found to have the highest thermodynamic stability. In the FM ground state, the calculated strength of the effective coupling between the magnetic moments of Mn atoms within the same layer approximately scales with the measured Curie temperatures of the bulk $M_2$MnSi compounds. In particular, the Co$_2$MnSi/Si(001) thin film has a robust FM ground state as in the bulk, and is found to be stable against a phase separation into CoSi/Si(001) and MnSi/Si(001) films. Hence this material is of possible use in FM-Si heterojunctions and deserves further experimental investigations.

description: A substantial administrative burden is placed on healthcare professionals as they manage and progress through their careers. Identity verification, pre-employment screening and appraisals: the bureaucracy associated with each of these processes takes precious time out of a healthcare professional's day. Time that could have been spent focused on patient care. In the midst of the COVID-19 crisis, it is more important than ever to optimize these professionals' time. This paper presents the synthesis of a design workshop held at the Royal College of Physicians of Edinburgh (RCPE) and subsequent interviews with healthcare professionals. The main research question posed is whether these processes can be re-imagined using digital technologies, specifically Self-Sovereign Identity? A key contribution in the paper is the development of a set of user-led requirements and design principles for identity systems used within healthcare. These are then contrasted with the design principles found in the literature. The results of this study confirm the need and potential of professionalising identity and credential management throughout a healthcare professional's career.

description: This article discusses the production of a mobile poetry app, conceived by members of the faculty of UBC's Critical Indigenous Studies unit and the current Poet Laureate of the City of Vancouver, and developed by a team of graduate students at UBC's Centre for Digital Media. While exploring and endorsing the underdeveloped cultural potential for digitally-enhanced, site-specific literary experiences and relational technology in general, the article also presents a narrative around a key point of contention that emerged among the app's designers during the creative process. Namely, how the use of standard styles of visual maps and navigational workflows in mobile apps amplify historical injustices deriving from settler colonialism's appropriation and use of land and labour. The narrative then follows the app designers' attempts to envision a novel human-computer wayfinding interface to transcend these problematic geographical norms, and deploy technology in such a way as to possibly restore equity to nonhuman entities like ecosystems, flora and fauna, and the land itself.

description: El trabajo ha cubierto un doble objetivo, por un lado se ha determinado la importancia relativa de los atributos del vino que influyen en la conformación de las preferencias de los consumidores de Castilla-La Mancha, y por otro se ha analizado la actitud de los consumidores hacia los vinos con certificación de Denominación de Origen (D.O.) más importantes de Castilla-La Mancha (D.O. La Mancha y D.O. Valdepeñas), con respecto al más conocido en el ámbito nacional (D.O. Rioja). Como resultado del primer objetivo, los atributos más relevantes son el precio, el color (tinto, blanco), la certificación y el origen, por este orden, y del segundo objetivo, se obtiene que la D.O. La Mancha y la D.O. Valdepeñas son percibidas como de vinos más baratos, de consumo más habitual y con una menor imagen de prestigio, mientras que los vinos de la D.O. Rioja son percibidos como vinos de prestigio y caros, por lo que su consumo se considera apropiado para ocasiones especiales. PALABRAS CLAVE: Denominación de Origen, Comportamiento del Consumidor, Análisis Conjunto, Simulación, Posicionamiento de Marcas. SUMMARY. This paper covers a dual objective. On the one hand, the relative importance was determined of the wine attributes that influence the formation of consumer preferences in Castilla-La Mancha. On the other, consumer attitude was analysed towards wine with Castilla-La Mancha's most important Designation of Origin (D.O.) certifications (D.O. La Mancha and D.O. Valdepeñas), compared with the best-known wine in the national ambit (D.O. Rioja). As a result of the first objective, the most relevant attributes are price, colour (red, white), certification and origin, in this order. The second objective shows that D.O. La Mancha and D.O. Valdepeñas are considered cheaper wines, of habitual consumption and a lower prestige image, while D.O. Rioja wines are seen as prestigious and expensive, so their consumption is considered appropriate for special occasions.

description: Previous work on applications of Abstract Differential Geometry (ADG) to discrete Lorentzian quantum gravity is brought to its categorical climax by organizing the curved finitary spacetime sheaves of quantum causal sets involved therein, on which a finitary (:locally finite), singularity-free, background manifold independent and geometrically prequantized version of the gravitational vacuum Einstein field equations were seen to hold, into a topos structure. This topos is seen to be a finitary instance of both an elementary and a Grothendieck topos, generalizing in a differential geometric setting, as befits ADG, Sorkin's finitary substitutes of continuous spacetime topologies. The paper closes with a thorough discussion of four future routes we could take in order to further develop our topos-theoretic perspective on ADG-gravity along certain categorical trends in current quantum gravity research.

description: RESUMEN - La evolución de la Política Agrícola Común (PAC) desde una política de apoyo a los precios hacia unos pagos más desconectados de la producción se enmarca en un contexto internacional más amplio, en el que otros países de la OCDE también reforman sus políticas en la misma dirección. El presente trabajo explica el significado del "desacoplamiento" de las políticas desde el punto de vista legal de la Organización Mundial de Comercio (OMC), y desde una perspectiva empírica como la adoptada por los trabajos de la OCDE. Se presentan los principales argumentos de eficiencia y distribución en favor del desacoplamiento y se analiza el alcance de las reformas en distintos países de la OCDE. Finalmente se argumenta en favor de la definición de unos objetivos nítidos que permitan diseñar de manera eficiente las política más apropiadas para alcanzarlos. PALABRAS CLAVE: desacoplamiento, Política Agrícola Común (PAC), países de la OCDE SUMMARY - The evolution of the Common Agricultural Policy (CAP) from price support to payments that are more decoupled from production is part of a broader international context in which other OECD countries have also reformed in a similar direction. This paper explains the meaning of "decoupling" from the legal perspective of the World Trade Organization (WTO), and from a more empirical approach as the one adopted by the OECD work on decoupling. The main arguments in favour of decoupling -both from efficiency and distribution considerations- are discussed and the scope of the reforms in different OECD countries is analyzed. Finally it is argued that a good definition of the objectives is needed in order to design the most appropriate policies.

description: Resumen : El objetivo de este trabajo es medir el cambio de la productividad en la agricultura chilena durante el período 1961-96. La Productividad Total de los Factores (PTF) fue calculada mediante índices Törnqvist. Los datos utilizados para estimar estos índices incluyen precios y cantidades de 51 cultivos, de la mano de obra, de la tierra, del capital y de factores intermedios. El análisis revela que mientras los productos crecieron un 2,69% anual, el uso de factores de producción bajó un 0,09%; por lo tanto, la PTF creció a una tasa promedio anual del 2,78% entre 1961 y 1996. Se realizó además un análisis para siete períodos correspondientes a diferentes regímenes políticos. La PTF creció a un promedio anual de 1,83% con Alessandri (1961-64), 3,12% bajo el período de Frei Montalva (1965-70), 1,52% durante Allende (1971-73), 6,11% en la primera parte del régimen de Pinochet y -0,28% en el segundo período de Pinochet (1981-89), 3,12% bajo Aylwin (1990-93) y 5,28% bajo Frei Ruiz-Tagle (1994-96). Los resultados sugieren que el programa de reforma agraria implementado en los sesenta no tuvo un efecto negativo en el crecimiento de la PTF. Palabras Claves: Productividad Total de los Factores; Indice Törnqvist; Agricultura; Chile Abstract: The main objective of this paper is to determine the productivity growth in the Chilean Agricultural sector during the 1961-1996 period. Total Factor Productivity (TFP) was calculated using the Törnqvist index, which is a discrete approximation to the Divisia index. The data used to estimate these indexes are prices and quantities for 51 crops, and for four inputs - labor, land, capital and intermediate factors. The rate of annual growth for the period 1961-96 was 2,69% and 0,09%, for products and inputs, respectively. Therefore, the TFP grew at an average annual rate of 2,78%. Given a significant annual variability in TFP growth, an analysis was carried out for seven sub-periods corresponding to different political regimes. TFP grew at an annual average of 1,83% with Alessandri (1961-64), 3,12% under the period of Frei Montalva (1965-70), 1,52% during the Allende years (1971-73), 6,11% during the first part of the Pinochet regime and 0,28% in the second period of Pinochet (1981-89), 3,12% during Aylwin (1990-93) and 5,28% under Frei Ruiz-Tagle (1994-96). The results suggest that the land reform program implemented in the 1960s did not have a negative effect on TFP growth, as has been previously argued by some authors.

description: The quantum-spin-Hall (QSH) phase of 2D topological insulators has attracted increased attention since the onset of 2D materials research. While large bulk gaps with vanishing edge gaps in atomically thin layers have been reported, verifications of the QSH phase by resistance measurements are comparatively few. This is partly due to the poor uniformity of the bulk gap induced by the substrate over a large sample area and/or defects induced by oxidation. Here, we report the observation of the QSH phase at room-temperature in the 1T'-phase of few-layer MoS2 patterned onto the 2H semiconducting phase using low-power and short-time laser beam irradiation. Two different resistance measurements reveal hallmark transport conductance values, ~e2/2h and e2/4h, as predicted by the theory. Magnetic-field dependence, scanning tunneling spectra, and calculations support the emergence of the room-temperature QSH phase. Although further experimental verification is still desirable, our results provide feasible application to room-temperature topological devices.

description: We introduce RPM-Net, a deep learning-based approach which simultaneously infers movable parts and hallucinates their motions from a single, un-segmented, and possibly partial, 3D point cloud shape. RPM-Net is a novel Recurrent Neural Network (RNN), composed of an encoder-decoder pair with interleaved Long Short-Term Memory (LSTM) components, which together predict a temporal sequence of pointwise displacements for the input point cloud. At the same time, the displacements allow the network to learn movable parts, resulting in a motion-based shape segmentation. Recursive applications of RPM-Net on the obtained parts can predict finer-level part motions, resulting in a hierarchical object segmentation. Furthermore, we develop a separate network to estimate part mobilities, e.g., per-part motion parameters, from the segmented motion sequence. Both networks learn deep predictive models from a training set that exemplifies a variety of mobilities for diverse objects. We show results of simultaneous motion and part predictions from synthetic and real scans of 3D objects exhibiting a variety of part mobilities, possibly involving multiple movable parts.
