description: The Walecka many-body field theory is investigated in the context of quantum nonextensive statistical mechanics, characterized by a dimensionless parameter $q$. We consider nuclear matter described statistically by a power-law distribution which generalizes the standard Fermi-Dirac distribution ($q = 1$). We show that the scalar and vector meson fields become more intense due to the nonextensive effects ($q \neq 1$). From a numerical treatment, we also show that as the nonextensive parameter $q$ increases, the nucleon effective mass diminishes and the equation of state becomes stiffer. Finally, the usual Maxwell construction seems not to be necessary for isotherms with temperatures in the range 14 Mev$

description: We give a simple introduction to the properties and use of ultrastable optical cavities, which are increasingly common in atomic and molecular physics laboratories for stabilizing the frequency of lasers to linewidths at the kHz level or below. Although the physics of Fabry-Perot interferometers is part of standard optics curricula, the specificities of ultrastable optical cavities, such as their high finesse, fixed length, and the need to operate under vacuum, can make their use appear relatively challenging to newcomers. Our aim in this work is to bridge the gap between generic knowledge about Fabry-Perot resonators and the specialized literature about ultrastable cavities. The intended audience includes students setting up an ultrastable cavity in a research laboratory for the first time and instructors designing advanced laboratory courses on optics and laser stabilization techniques.

description: Large-scale interaction networks of human communication are often modeled as complex graph structures, obscuring temporal patterns within individual conversations. To facilitate the understanding of such conversational dynamics, episodes with low or high communication activity as well as breaks in communication need to be detected to enable the identification of temporal interaction patterns. Traditional episode detection approaches are highly dependent on the choice of parameters, such as window-size or binning-resolution. In this paper, we present a novel technique for the identification of relevant episodes in bi-directional interaction sequences from abstract communication networks. We model communication as a continuous density function, allowing for a more robust segmentation into individual episodes and estimation of communication volume. Additionally, we define a tailored feature set to characterize conversational dynamics and enable a user-steered classification of communication behavior. We apply our technique to a real-world corpus of email data from a large European research institution. The results show that our technique allows users to effectively define, identify, and analyze relevant communication episodes.

Belgian avant-gardism, 1887-1889 : Les Vingt, L’Art Moderne and the utopian vision
Creators: name: DeFina, Carol Ann
Publisher: name: University of British Columbia
Year: 2010

description: In 1883 a group of Belgian artists wishing to challenge the hegemony of the Brussels Academy founded the organization, Les Vingt, on the principles of egalitarianism and artistic freedom and elected Octave Maus, editor of the self-proclaimed avant-garde journal, L'Art Moderne, as its secretary. Henceforth, Les Vingt assumed the identity of Belgium's leading visual exponent of modernité and L'Art Moderne became its foremost champion. In actuality, the alliance the Vingtistes formed with L'Art Moderne allowed Octave Maus and his co-editor Edmund Picard to gain control of the group's operations. The journal's editors, through their association with the Belgian social reform movement, had formulated an artistic concept they called l'art social and Les Vingt was to become the incarnation of this new doctrine of social art. During the period of 1887 to 1889, however, while the Belgian workers' movement erupted in a succession of strikes and demonstrations, Maus and Picard radically changed their strategy in marketing Les Vingt to its viewing public. They campaigned for a revised, "depoliticized" avant-garde identity for the group, and the model they chose to represent this new identity was French divisionism. The group's appropriation of divisionism, however, signified a forfeiture of many of the group's original ideals. Furthermore, it became a point of conflict for those Vingtistes who chose to remain loyal to their own styles. This conflict is evident in the case of James Ensor, one of the group's important founding members. During this period, he developed his own personal imagery that was a synthesis of Flemish and modern themes and motifs. This imagery made a bold, critical attack upon Les Vingt's capitulation to French divisionism, which signified an acqui-esence to the ardently Francophile tastes of the Brussels bourgeoisie. The focus of this thesis is an analysis of Les Vingt's avant-garde identity as it evolved out of its relationship with L'Art Moderne, and how that relationship led to the importation of divisionism. Ensor's conflict with Les Vingt and his provocative Flemish imagery is also examined as a means of assessing the significance of Les Vingt's adoption of the French art style.

description: We develop a robust method to extract the pole configuration of a given partial-wave amplitude. In our approach, a deep neural network is constructed where the statistical errors of the experimental data are taken into account. The teaching dataset is constructed using a generic S-matrix parametrization, ensuring that all the poles produced are independent of each other. The inclusion of statistical error results into a noisy classification dataset which we should solve using the curriculum method. As an application, we use the elastic $πN$ amplitude in the $I(J^P)=1/2(1/2^{-})$ sector where $10^6$ amplitudes are produced by combining points in each error bar of the experimental data. We fed the amplitudes to the trained deep neural network and find that the enhancements in the $πN$ amplitude are caused by one pole in each nearby unphysical sheet and at most two poles in the distant sheet. Finally, we show that the extracted pole configurations are independent of the way points in each error bar are drawn and combined, demonstrating the statistical robustness of our method.

Nature of $X(3872)$ from its radiative decay

description: We study the radiative decay of $X(3872)$ based on the assumption that $X(3872)$ is regarded as a $c\overline{c}$ charmonium with quantum number $J^{PC}=1^{++}$ ($J,\,P,\,C$ represent the spin, parity and charge conjugation, respectively). The form factors of $X(3872)$ transitions to $J/ψγ$ and $ψ'γ$ ($ψ'$ denotes $ψ(2S)$ throughout the paper) are calculated in the framework of the covariant light-front quark model. The phenomenological wave function of a meson depends on the parameter $β$, whose inverse essentially describes the confinement scale. In the present work, the parameters $β$ for the vector $J/ψ$ and $ψ'$ mesons will be determined through their decay constants, which are obtained from the experimental values of their partial decay widths to the electron-positron pair. For $X(3872)$, we determined the value of $β$ by the decay width of $X(3872)\rightarrow ψ'γ$. Then, we examined the width of $X(3872)\to J/ψγ$ in a manner of parameter-free prediction and compared it with the experimental value. As a result, an inconsistency or contradiction occurs between the widths of $X(3872)\to J/ψγ$ and $X(3872)\to ψ'γ$. We thus conclude that $X(3872)$ cannot be a pure $c\overline c$ resonance and that other components are necessary in its wave function.

description: Many of today's online services provide personalized recommendations to their users. Such recommendations are typically designed to serve certain user needs, e.g., to quickly find relevant content in situations of information overload. Correspondingly, the academic literature in the field largely focuses on the value of recommender systems for the end user. In this context, one underlying assumption is that the improved service that is achieved through the recommendations will in turn positively impact the organization's goals, e.g., in the form of higher customer retention or loyalty. However, in reality, recommender systems can be used to target organizational economic goals more directly by incorporating monetary considerations such as price awareness and profitability aspects into the underlying recommendation models. In this work, we survey the existing literature on what we call Economic Recommender Systems based on a systematic review approach that helped us identify 133 relevant papers. We first categorize existing works along different dimensions and then review the most important technical approaches from the literature. Furthermore, we discuss common methodologies to evaluate such systems and finally outline the limitations of today's research and future directions.

description: We consider a one-dimensional chain of N equidistantly spaced noninteracting qubits embedded in an open waveguide. In the frame of single-excitation subspace, we systematically study the evolution of qubits amplitudes if the only qubit in the chain was initially excited. We show that the temporal dynamics of qubits amplitudes crucially depend on the value of kd, where k is the wave vector, d is a distance between neighbor qubits. If kd is equal to an integer multiple of $π$, then the qubits are excited to a stationary level which scales as SN^{-1}S. We show that in this case, it is the dark states which prevent qubits from decaying to zero even though they do not contribute to the output spectrum of photon emission. For other values of kd the excitations of qubits have the form of damping oscillations, which represent the vacuum Rabi oscillations in a multi-qubit system. In this case, the output spectrum of photon radiation is defined by a subradiant state with the smallest width.

description: Current densities are induced in the electronic structure of molecules when they are exposed to external magnetic fields. Aromatic molecular rings sustain net diatropic ring currents, whereas the net ring current in antiaromatic molecular rings is paratropic and flows in the opposite, non-classical direction. We present computational methods and protocols to calculate, analyse and visualise magnetically induced current densities in molecules. Calculated ring-current strengths are used for quantifying the degree of aromaticity. The methods have been demonstrated by investigating ring-current strengths and the degree of aromaticity of aromatic, antiaromatic and non-aromatic six-membered hydrocarbon rings. Current-density pathways and ring-current strengths of aromatic and antiaromatic porphyrinoids and other polycyclic molecules have been studied. The aromaticity and current density of Möbius-twisted molecules has been investigated to find the dependence on the twist and the spatial deformation of the molecular ring. Current densities of fullerene, gaudiene and toroidal carbon nanotubes have also been studied.

description: Massive black hole binaries (MBHBs) could be the loudest gravitational-wave (GW) sources in milli-Hertz (mHz) GW band, but their dynamical evolution may stall when the black holes reach the innermost parsec of a galaxy. Such a "final-parsec problem" could be solved if MBHB forms in a gas-rich environment, such as an active galactic nucleus (AGN), but other solutions not involving AGNs also exist. Testing the correlation between these mHz GW sources and AGNs is difficult in real observation because AGNs are ubiquitous. To overcome this difficult, we use a statistical method, first designed to constrain the host galaxies of stellar-mass binary black holes, to search for a MBHB-AGN correlation in different astrophysical scenarios. We find that by detecting only one MBHB at $z \lesssim 0.5$, a mHz GW detector, such as the Laser Interferometer Space Antenna (LISA), can already distinguish different merger scenarios thanks to the precise localization of the source. Future detector networks and deeper AGNs surveys can further testify the MBHB-AGN correlation up to a redshift of $z\sim 2$ even if only a small fraction of MBHBs merge inside AGNs. These constraints will help settle the long-standing debate on the possible solutions to the final-parsec problem.

description: La bambola, nelle sue svariate manifestazioni di sostituto della donna reale, da almeno quarant’anni a questa parte è un soggetto al centro delle poetiche di tanti artisti che attraverso essa veicolano stereotipi, idee ed esperienze legate all’universo femminile. Eppure nel corso del tempo è profondamente mutato il modo di intendere e rappresentare questo oggetto, che è uno dei più discussi e controversi dei nostri tempi proprio per l’inquietante familiarità che non lascia indifferente chi lo osserva. Soprattutto nel caso delle real dolls o sex dolls, così verosimili e curate nei minimi dettagli da sembrare reali. Trascurando le polemiche e gli aspetti legati al discutibile business erotico di cui queste bambole fanno parte, ciò che non si può ignorare è che sempre più spesso esse sono al centro di progetti d’arte che sembrano veri e propri studi psicologici intorno alla sfera emotiva dell’individuo.
Sono numerosi gli artisti che attraverso un abile uso dello strumento fotografico, unito a set studiati nei minimi particolari, agli accessori e alle pose, impegnano la propria ricerca intorno alla possibilità di far trasparire sentimenti da un soggetto che notoriamente non può provarli.
Ma perché è così importante dotare di un’anima questi corpi inanimati? Perché abbiamo tanto bisogno di questi surrogati per far emergere sentimenti ed emozioni umane?
Dopo l’uso smodato e ossessivo della poetica della bambola in ambito surrealista, a partire dagli anni Settanta questo soggetto viene recuperato e utilizzato come una sorta di specchio in cui far riflettere quel processo di manipolazione e reificazione di un corpo dalla fisicità sempre più artificiale, e dei progressi della chirurgia plastica e dell’ingegneria genetica come tappe cruciali della costruzione di un uomo-macchina-cosa. Tra gli esponenti di quest’arte, notoriamente definita post-umana, vi sono il pioniere Helmut Newton, seguito da Cindy Sherman, Nick Knight, Charles Ray e Vanessa Beecroft, solo per citarne alcuni.
Ciò che tuttavia viene indagato è l’inversione di marcia che possiamo notare in molti artisti. Nelle poetiche di Laurie Simmons, Beatrice Morabito, Azusa Itagaki e Elena Dorfman, emerge l’urgenza di recuperare umanità e vulnerabilità, caratteristiche che i messaggi massmediali hanno a lungo tentato di annullare in nome di una spersonalizzante omologazione e della cultura del successo a tutti i costi. È così che la bambola da classico stereotipo della donna-oggetto, di un corpo sempre più manipolato e artificiale, diventa un soggetto da amare e di cui prendersi cura o con cui condividere esperienze reali ed affettive. Riflesso di una società affetta da autismo e narcisismo?

I emphasize the theoretical-model dependence of these results. I discuss supersymmetric dark matter constraints at colliders (mainly LHC) in various theoretical contexts: the standard Cosmological-Constant-Cold-Dark-Matter (Lambda-CDM) model, (super)string-inspired ones and non-equilibrium relaxation dark energy models. I then investigate the capability of LHC measurements in asserting whether supersymmetric matter (if discovered) constitutes part, or all, of the astrophysical dark matter. I also discuss prospects for improving the constraints in future precision facilities, such as the International Linear Collider.

description: The pion-nucleon bremsstrahlung $π+N\Longrightarrowγ'+π'+N'$ is studied in a new form of current conservation. According to this condition, the internal and external particle radiation parts of the $πN$ radiation amplitude have opposite signs, i.e., they contain terms which must cancel each other. Therefore, one has a screening of the internal and external particle radiation in the $πN$ bremsstrahlung. In particular, it is shown that the double $Δ$ exchange diagram with the $Δ-γ' Δ'$ vertex cancel against the appropriate longitudinal part of the external particle radiation diagrams. Consequently, a model independent relation between the magnetic dipole moments of the $Δ^+$ and $Δ^{++}$ resonances and the anomalous magnetic moment of the proton $μ_p$ is obtained, where $μ_Δ$ is expressed by $μ_p$ as $μ_{Δ^+}={{M_Δ}\over {m_p}} μ_p$ and $μ_{Δ^{++}}={3\over 2}μ_{Δ^+}$ in agreement with the values extracted from the fit for the experimental cross section of the $π^+ p\toγ'π^+ p$ reaction.

description: We study the gravitational wave (GW) spectrum produced by acoustic waves in the early universe, such as would be produced by a first order phase transition, focusing on the low-frequency side of the peak. We confirm with numerical simulations the Sound Shell model prediction of a steep rise with wave number $k$ of $k^9$ to a peak whose magnitude grows at a rate $(H/k_\text{p})H$, where $H$ is the Hubble rate and $k_\text{p}$ the peak wave number, set by the peak wave number of the fluid velocity power spectrum. We also show that hitherto neglected terms give a shallower part with amplitude $(H/k_\text{p})^2$ in the range $H \lesssim k \lesssim k_\text{p}$, which in the limit of small $H/k$ rises as $k$. This linear rise has been seen in other modelling and also in direct numerical simulations. The relative amplitude between the linearly rising part and the peak therefore depends on the peak wave number of the velocity spectrum and the lifetime of the source, which in an expanding background is bounded above by the Hubble time $H^{-1}$. For slow phase transitions, which have the lowest peak wave number and the loudest signals, the acoustic GW peak appears as a localized enhancement of the spectrum, with a rise to the peak less steep than $k^9$. The shape of the peak, absent in vortical turbulence, may help to lift degeneracies in phase transition parameter estimation at future GW observatories.

description: We show how gauge coupling unification near the Planck scale $M_P\sim 10^{19}$ GeV can be achieved in the framework of supersymmetry, facilitating a full unification of all forces with gravity. Below the conventional GUT scale $M_{GUT}\sim 10^{16}$ GeV physics is described by a Supersymmetric Standard Model whose particle content is that of three complete $\mathbf{27}$ representations of the gauge group $E_6$. Above the conventional GUT scale the gauge group corresponds to a left-right symmetric Supersymmetric Pati-Salam model, which may be regarded as a ``surrogate SUSY GUT'' with all the nice features of SO(10) but without proton decay or doublet-triplet splitting problems. At the TeV scale the extra exotic states may be discovered at the LHC, providing an observable footprint of an underlying $E_6$ gauge group broken at the Planck scale. Assuming an additional low energy $U(1)_X$ gauge group, identified as a non-trivial combination of diagonal $E_6$ generators, the $μ$ problem of the MSSM can be resolved.

description: In this paper we complete the set of diagnostic tools for synchrotron emitting sources presented by Del Zanna et al. (Astron. Astrophys. 453, 621, 2006) with the computation of inverse Compton radiation from the same relativistic particles. Moreover we investigate, for the first time, the gamma-ray emission properties of Pulsar Wind Nebulae in the light of the axisymmetric jet-torus scenario. The method consists in evolving the relativistic MHD equations and the maximum energy of the emitting particles. The particle energy distribution function is split in two components: the radio one connected to a relic population born at the outburst of the supernova and the other associated to the wind population continuously accelerated at the termination shock and emitting up to the gamma-ray band. We consider the general Klein-Nishina cross section and three different photon targets: the nebular synchrotron photons, far-infrared thermal ones and the cosmic microwave background. The overall synchrotron spectrum is fitted assuming an excess of injected particles and a steeper power law with respect to previous models. The TeV emission has the correct shape but is in excess of the data. This is due to the nebular magnetic field structure as obtained by the simulations. The jet-torus morphology is visible in high-resolution gamma-ray synthetic maps too. We present a preliminary exploration of time variability in the X and gamma-ray bands.

description: Machine understanding of user utterances in conversational systems is of utmost importance for enabling engaging and meaningful conversations with users. Entity Linking (EL) is one of the means of text understanding, with proven efficacy for various downstream tasks in information retrieval. In this paper, we study entity linking for conversational systems. To develop a better understanding of what EL in a conversational setting entails, we analyze a large number of dialogues from existing conversational datasets and annotate references to concepts, named entities, and personal entities using crowdsourcing. Based on the annotated dialogues, we identify the main characteristics of conversational entity linking. Further, we report on the performance of traditional EL systems on our Conversational Entity Linking dataset, ConEL, and present an extension to these methods to better fit the conversational setting. The resources released with this paper include annotated datasets, detailed descriptions of crowdsourcing setups, as well as the annotations produced by various EL systems. These new resources allow for an investigation of how the role of entities in conversations is different from that in documents or isolated short text utterances like queries and tweets, and complement existing conversational datasets.

description: Building a \BBz experiment with the ability to probe neutrino mass in the inverted hierarchy region requires the combination of a large detector mass sensitive to \BBz, on the order of 1-tonne, and unprecedented background levels, on the order of or less than 1 count per year in the \BBz signal region. The MAJORANA Collaboration proposes a design based on using high-purity enriched Ge-76 crystals deployed in ultra-low background electroformed Cu cryostats and using modern analysis techniques that should be capable of reaching the required sensitivity while also being scalable to a 1-tonne size. To demonstrate feasibility, the collaboration plans to construct a prototype system, the MAJORANA DEMONSTRATOR, consisting of 30 kg of 86% enriched \Ge-76 detectors and 30 kg of natural or isotope-76-depleted Ge detectors. We plan to deploy and evaluate two different Ge detector technologies, one based on a p-type configuration and the other on n-type.

description: We report the first Nernst effect measurement on the new iron-based superconductor LaO$_{1-x}$F$_{x}$FeAs $(x=0.1)$. In the normal state, the Nernst signal is negative and very small. Below $T_{c}$ a large positive peak caused by vortex motion is observed. The flux flowing regime is quite large compared to conventional type-II superconductors. However, a clear deviation of the Nernst signal from normal state background and an anomalous depression of off-diagonal thermoelectric current in the normal state between $T_{c}$ and 50 K are observed. We propose that this anomaly in the normal state Nernst effect could correlate with the SDW fluctuations.

description: High-resolution observations of ionized and molecular gas in the nuclear regions of galaxies are indispensable for delineating the interplay of star formation, gaseous inflows, stellar radiation, and feedback processes. Combining our new ALMA band 3 mapping and archival VLT/MUSE data, we present a spatially resolved analysis of molecular and ionized gas in the central 5.4 Kpc region of NGC 1365. We find the star formation rate/efficiency (SFR/SFE) in the inner circumnuclear ring is about 0.4/1.1 dex higher than in the outer regions. At a linear resolution of 180 pc, we obtain a super-linear Kennicutt-Schmidt law, demonstrating a steeper slope (1.96$\pm$0.14) than previous results presumably based on lower-resolution observations. Compared to the northeastern counterpart, the southwestern dust lane shows lower SFE, but denser molecular gas, and larger virial parameters. This is consistent with an interpretation of negative feedback from AGN and/or starburst, in the sense that the radiation/winds can heat and interact with the molecular gas even in relatively dense regions. After subtracting the circular motion component of the molecular gas and the stellar rotation, we detect two prominent non-circular motion components of molecular and ionized hydrogen gas, reaching a line-of-sight velocity of up to 100 km/s. We conclude that the winds or shocked gas from the central AGN may expel the low-density molecular gas and diffuse ionized gas on the surface of the rotating disk.

The residential construction industry : problems in shifting from new construction to renovation activities
Creators: name: Dodds, Carol
Publisher: name: University of British Columbia
Year: 2010

description: This thesis studies the response of the residential construction industry to the growing market for residential renovation, and its ability and willingness to transfer operations into renovation activities. The industry includes firms specializing in land development, new house-building, speculative and contract renovation projects. The thesis is concerned with the inherent industry constraints in meeting housing demand. The increasing importance of residential renovation relative to new housing construction is examined. A review of the new residential and renovation sectors follows, comparing and contrasting the nature and characteristics of both sectors. It is found that small and medium-sized firms within the new residential construction sector are most able to enter into residential renovation activities. The thesis reveals that the industry has so far shown a small scale response to the potential market for residential renovation, and has been inhibited by a number of barriers to entry. These include rigidities in the institutional approach to the residential renovation construction process. Other barriers arise from the inherent differences between renovation and new construction activities. Proposals are made to facilitate a more effective and efficient renovation construction process. These should induce the industry to be more able and willing to adjust to the increased pace and scale of residential renovation activity expected in the future. In turn, the maintenance and rejuvenation of the existing housing stock will be facilitated in accordance with future housing demand.

description: The diffuse $γ$-ray spectrum at sub-PeV energy region has been measured for the first time by the Tibet-AS$γ$ experiment. It will shed new light on the understanding of origin and propagation of Galactic cosmic rays at very high energies. It has been pointed out that the traditional cosmic ray propagation model based on low energy measurements undershoot the new data, and modifications of the model with new ingredients or alternative propagation framework is required. In this work, we propose that the hadronic interactions between freshly accelerated cosmic rays and the medium surrounding the sources, which was neglected in the traditional model, can naturally account for the Tibet-AS$γ$ diffuse emission. We show that this scenario gives a consistent description of other secondary species such as the positron spectrum, the boron-to-carbon ratio, and the antiproton-to-proton ratio. As a result, the electron spectrum above 10 TeV will have a hardening due to this secondary component, which may be tested by future measurements.

description: This paper presents a differential geometric control approach that leverages SE(3) group invariance and equivariance to increase transferability in learning robot manipulation tasks that involve interaction with the environment. Specifically, we employ a control law and a learning representation framework that remain invariant under arbitrary SE(3) transformations of the manipulation task definition. Furthermore, the control law and learning representation framework are shown to be SE(3) equivariant when represented relative to the spatial frame. The proposed approach is based on utilizing a recently presented geometric impedance control (GIC) combined with a learning variable impedance control framework, where the gain scheduling policy is trained in a supervised learning fashion from expert demonstrations. A geometrically consistent error vector (GCEV) is fed to a neural network to achieve a gain scheduling policy that remains invariant to arbitrary translation and rotations. A comparison of our proposed control and learning framework with a well-known Cartesian space learning impedance control, equipped with a Cartesian error vector-based gain scheduling policy, confirms the significantly superior learning transferability of our proposed approach. A hardware implementation on a peg-in-hole task is conducted to validate the learning transferability and feasibility of the proposed approach.
Taxonomy of scalar potential with U-dual fluxes

description: In the context of $N =1$ four-dimensional type IIB supergravity theories, the U-dual completion arguments suggest to include four S-dual pairs of fluxes in the holomorphic superpotential, namely the so-called $(F, \, H), \, (Q, \, P), \, (P^\prime, Q^\prime)$ and $(H^\prime, \, F^\prime)$. These can generically induce cubic polynomials for the complex-structure moduli as well as the Kähler-moduli in the flux superpotential. In this article, we explore the insights of the four-dimensional non-geometric scalar potential in the presence of such generalized U-dual fluxes by considering an explicit type IIB toroidal compactification model based on an orientifold of ${\mathbb T}^6/({\mathbb Z}_2 \times {\mathbb Z}_2)$ orbifold. First, we observe that the flux superpotential induces a huge scalar potential having a total of 76276 terms involving 128 flux parameters and 14 real scalars. Subsequently, we invoke a new set of (the so-called) ``axionic fluxes" comprising combinations of the standard fluxes and the RR axions, and it turns out that these axionic fluxes can be very useful in rewriting the scalar potential in a relatively compact form. In this regard, using the metric of the compactifying toroidal sixfold, we present a new formulation of the effective scalar potential, which might be useful for understanding the higher-dimensional origin of the various pieces via the so-called ``dimensional oxidation" process. We also discuss the generalized Bianchi identities and the tadpole cancellation conditions, which can be important while seeking the physical (AdS/dS) vacua in such models.

description: Airborne LiDAR systems have the capability to capture the Earth's surface by generating extensive point cloud data comprised of points mainly defined by 3D coordinates. However, labeling such points for supervised learning tasks is time-consuming. As a result, there is a need to investigate techniques that can learn from unlabeled data to significantly reduce the number of annotated samples. In this work, we propose to train a self-supervised encoder with Barlow Twins and use it as a pre-trained network in the task of semantic scene segmentation. The experimental results demonstrate that our unsupervised pre-training boosts performance once fine-tuned on the supervised task, especially for under-represented categories.
