description: Haliplus (Liaphlus) fulvus (Fabricius, 1801) NEW BRUNSWICK: York Co., New Maryland, Charters Settlement, 45° 49.55΄ N, 66° 43.32΄ W, 18.V.2003, R. P. Webster, coll., mixed forest in small eutrophic pond in dense vegetation (4, RWC). This widely distributed Holarctic species was formerly known in North America as Haliplus (Liaphlus) subguttatus Crotch, 1873 and Haliplus (Liaphlus) salinarius Wallis, 1933, two names that were synonymized by Vondel (1991). Brigham (1996) accepted the synonymy of H. fulvus and H. salinarius, but disagreed about H. subguttatus. Since 1991, long series of both Nearctic species have been examined by BJV, but no reliable characters have been found to distinguish the two species and the shape of the aedeagus of H. subguttatus falls within the range of variation exhibited by specimens of H. fulvus. Accordingly, the synonymy of Vondel (1991) is maintained here. This species was recorded from Nova Scotia by Wallis (1933), and then from Newfoundland by Roughley (1991) and Vondel (1991) (Fig. 1). In the Old World it is widely distributed from Iceland throughout Europe, south to North Africa, east through the Middle East, south to Iraq, and across Central Asia and Siberia as far as Lake Baikal (Vondel 1991). Vondel (1991) summarized its biology, indicating that it is found in clear or peaty stagnant or slowly running water, in lakes, pools, canals, rivers, and ditches, and has even been recorded in brackish water. Larvae probably feed on algae such as Nitella while adults are omnivorous feeding on algae, pollen, and invertebrates such as oligochaetes.

description: Miniaturized optical imaging systems typically utilize 2-dimensional (2D) actuators to acquire images over a 2D field of view (FOV). Piezoelectric tubes are most compact, but usually produce sub-millimeter FOVs and are difficult to fabricate at scale, leading to high costs. Planar piezoelectric bending actuators (benders) are capable of much larger actuations and are substantially lower cost, but inadequate for 2D steering. We presented a multi-beam fiber scanning platform that generated multi-millimeter 2D scans with a 1D actuator by maximizing the mechanical coupling effect in its orthogonal axis. We further expanded the FOV by demonstrating mosaiced fields driven with spiral and cycloid trajectories, where three optical fibers were optimized to resonate with identical paths in synchronicity. Leveraging optical coherence tomography with a long coherence length laser, we acquired depth-multiplexed images of biological samples at 12.6 um resolution. This multi-fold improvement in scanning coverage and cost-effectiveness promises to accelerate the advent of piezoelectric optomechanics in compact devices such as endoscopes and headsets, and miniaturized microscopes at point-of-care.

Il calcio all’università

description: Questo numero del “Semestrale di Studi e Ricerche di Geografia” si
distingue da tutti gli altri, che compaiono nella Collana del Dipartimento
di Geografia umana della Sapienza Università di Roma, giacché è la
prima volta che viene analizzata un’esperienza didattica (Geografia del
calcio) effettuata nell’ambito dei percorsi didattici dei Corsi di laurea
geografici: triennale e biennale. Tale circostanza, peraltro, testimonia la
stretta relazione da sempre esistente tra il Dipartimento di Geografia
umana e i rispettivi Corsi di laurea.
La stessa compagine che ha partecipato a questa attività di insegnamento,
costituita da docenti ed esperti di varia estrazione disciplinare e
professionale, rappresenta un altro elemento di novità, che sottolinea uno
degli aspetti più interessanti rilevabile nell’ultima riforma dell’Università:
l’apertura del mondo accademico alle realtà culturali, economiche e
politiche presenti nella società. E proprio l’inserimento dell’iniziativa
nelle “Altre attività formative”, riscontrabili nei curricola universitari, ha
consentito di valorizzare al meglio le opportunità offerte dalla riforma.
Non mi dilungo sugli aspetti formali e istituzionali che sono stati
puntualmente trattati nel contributo scritto da Riccardo Morri, mentre
mi sembra che vada segnalato, anche se non meraviglia più di tanto per
l’influenza che il calcio riveste nella società, la notevole risonanza che
l’iniziativa dei Corsi di laurea ha suscitato nei mass media (giornali, radio,
televisione, Internet).

description: We explore the observational appearance of the merger of a low-mass star with a white dwarf (WD) binary companion. We are motivated by Schreiber et al. (2016), who found that multiple tensions between the observed properties of cataclysmic variables (CVs) and standard evolution models are resolved if a large fraction of CV binaries merge as a result of unstable mass transfer. Tidal disruption of the secondary forms a geometrically thick disk around the WD, which subsequently accretes at highly super-Eddington rates. Analytic estimates and numerical hydrodynamical simulations reveal that outflows from the accretion flow unbind a large fraction >~ 90% of the secondary at velocities ~500-1000 km/s within days of the merger. Hydrogen recombination in the expanding ejecta powers optical transient emission lasting about a month with a luminosity > 1e38 erg/s, similar to slow classical novae and luminous red novae from ordinary stellar mergers. Over longer timescales the mass accreted by the WD undergoes hydrogen shell burning, inflating the remnant into a giant of luminosity ~300-5000 L_sun, effective temperature T_eff ~ 3000 K and lifetime ~1e4-1e5 yr. We predict that ~1e3-1e4 Milky Way giants are CV merger products, potentially distinguishable by atypical surface abundances. We explore whether any Galactic historical slow classical novae are masquerading CV mergers by identifying four such post-nova systems with potential giant counterparts for which a CV merger origin cannot be ruled out. We address whether the historical transient CK Vul and its gaseous/dusty nebula resulted from a CV merger.

description: We introduce an efficient and accurate readout measurement scheme for single and multi-qubit states. Our method uses Bayesian inference to build an assignment probability distribution for each qubit state based on a reference characterization of the detector response functions. This allows us to account for system imperfections and thermal noise within the assignment of the computational basis. We benchmark our protocol on a quantum device with five superconducting qubits, testing initial state preparation for single and two-qubit states and an application of the Bernstein-Vazirani algorithm executed on five qubits. Our method shows a substantial reduction of the readout error and promises advantages for near-term and future quantum devices.

description: Nereid is a small irregular moon of Neptune that displays large-, moderate-, and small-amplitude photometric variations on both fast and slow time scales. The central mystery of Nereid is now to explain the physical mechanism of these unique brightness changes and why they change with time. To characterize Nereid's variability, we have been using the SMARTS telescopes on Cerro Tololo for synoptic monitoring from 1999 to 2006. We present a well-sampled photometric time series of 493 magnitudes on 246 nights mostly in the V-band. In combination with our earlier data (for 774 magnitudes over 362 nights), our 20-year data set is the most comprehensive for any small icy body in our Solar System. Our yearly light curves show that Nereid displays various types of behaviors: large amplitude brightenings and fadings (1987 to 1990); moderate-amplitude variation about the average phase curve (1993-1997, 2003, 2005), moderate-amplitude variation and systematically brighter by roughly one-quarter magnitude throughout the entire season (2004); and nearly constant light curves superimposed on a surprisingly large-amplitude opposition surge (1998, 1999, 2000, 2006). Other than in 2004, Nereid's variations were closely centered around a constant phase curve that is well fit with a Hapke model for the coherent backscattering opposition surge mechanism with angular scale of 0.7+-0.1 degrees. In our entire data set from 1987-2006, we find no significant periodicity. We propose that the year-to-year changes in the variability of Nereid are caused by forced precession (caused by tidal forces from Neptune) on the spin axis of a nonspherical Nereid, such that cross-sectional areas and average albedos change as viewed from Earth.

description: Egorov's theorem for transversally elliptic operators, acting on sections of a vector bundle over a compact foliated manifold, is proved. This theorem relates the quantum evolution of transverse pseudodifferential operators determined by a first order transversally elliptic operator with the (classical) evolution of its symbols determined by the parallel transport along the orbits of the associated transverse bicharacteristic flow. For a particular case of a transverse Dirac operator, the transverse bicharacteristic flow is shown to be given by the transverse geodesic flow and the parallel transport by the parallel transport determined by the transverse Levi-Civita connection. These results allow us to describe the noncommutative geodesic flow in noncommutative geometry of Riemannian foliations.

Il viaggio come scoperta e incontro

description: journey as discovery and meeting
The journey has a vast polysemous meaning which remains strong even though
narrowing its meanings to more specifically geographical contents. The «act of
moving from one place to another» has a spatial value, which is founded in
fundamental geographical terms like distance and orientation, to the more
complex ones like globalisation. Change and complexity are strategic concepts
of modern geography, which find considerable confirmation in the acceleration
taking place in the mobility of people and goods. And mobility (tourism and the
migratory phenomenon are significant expressions of this, despite their huge
differences) produces new forms of discovery and meeting.
Keywords
Mobility, distance, tourism, intercultural.

Le voyage en tant que découverte et rencontre
Le voyage renvoie à la polysémie d’un vaste champ sémantique et tout cela est
vrai même si l’on le regarde d’un point de vue géographique. L’acte de se déplacer d’un lieu à l’autre a une valeur intrinsèque qui est liée à l’espace, bien
sûr, reposant sur des termes géographiques fondamentaux tels que la distance
ou l’orientation jusqu’à ceux plus complexes, par exemple la mondialisation. La
géographie contemporaine a choisi le changement et la complexité en tant que
concepts stratégiques. La mobilité, chaque jour plus accélérée, des personnes et
des marchandises en est la cause première. C’est donc la mobilité même qui
crée à son tour de nouvelles formes de découverte et de rencontre (le tourisme
et le phénomène migratoire peuvent en représenter, au-delà des différences,
des expressions significatives et importantes).

It was reported from Nova Scotia by Downie and Arnett (1996), however, we have not found specimens in any reference collection consulted, there are no published specimen records of the species from Nova Scotia, and it was not reported from the province by Roughley (1991). Consequently we remove it from the faunal list of Nova Scotia. However, since it has been found in neighbouring New Brunswick it should be sought in Nova Scotia.

description: We address the interesting temperature range of a glass forming system where the mechanical properties are intermediate between those of a liquid and a solid. We employ an efficient Monte-Carlo method to calculate the elastic moduli, and show that in this range of temperatures the moduli are finite for short times and vanish for long times, where `short' and `long' depend on the temperature. By invoking some exact results from statistical mechanics we offer an alternative method to compute shear moduli using Molecular Dynamics simulations, and compare those to the Monte-Carlo method. The final conclusion is that these systems are not "viscous fluids" in the usual sense, as their actual time-dependence concatenates solid-like materials with varying local shear moduli.

description: The possible existence of a liquid-liquid critical point in deeply supercooled water has been a subject of debate in part due to the challenges associated with providing definitive experimental evidence. Pioneering work by Mishima and Stanley [Nature 392, 164 (1998) and Phys. Rev. Lett. 85, 334 (2000)] sought to shed light on this problem by studying the melting curves of different ice polymorphs and their metastable continuation in the vicinity of the expected location of the liquid-liquid transition and its associated critical point. Based on the continuous or discontinuous changes in slope of the melting curves, Mishima suggested that the liquid-liquid critical point lies between the melting curves of ice III and ice V. Here, we explore this conjecture using molecular dynamics simulations with a purely-predictive machine learning model based on ab initio quantum-mechanical calculations. We study the melting curves of ices III, IV, V, VI, and XIII using this model and find that the melting lines of all the studied ice polymorphs are supercritical and do not intersect the liquid-liquid transition locus. We also find a pronounced, yet continuous, change in slope of the melting lines upon crossing of the locus of maximum compressibility of the liquid. Finally, we analyze critically the literature in light of our findings, and conclude that the scenario in which melting curves are supercritical is favored by the most recent computational and experimental evidence. Thus, although the preponderance of experimental and computational evidence is consistent with the existence of a second critical point in water, the behavior of the melting lines of ice polymorphs does not provide strong evidence in support of this viewpoint, according to our calculations.

This emergent functionality poses a challenge to safety assurance. The main contribution of this paper is a process for the safety assurance of emergent behaviour in autonomous robotic swarms called AERoS, following the guidance on the Assurance of Machine Learning for use in Autonomous Systems (AMLAS).

We obtain asymptotic expressions and also show how corrections can be calculated perturbatively. We pay special attention to low-frequency modes in anti-de Sitter space because they govern the hydrodynamic properties of a gauge theory fluid according to the AdS/CFT correspondence. The latter may have experimental consequencies for the quark-gluon plasma formed in heavy ion collisions.

Probing the uniaxial strain-dependent valley drift and Berry curvature in monolayer MoSi$_2$N$_4$

description: We use ab initio calculations and theoretical analysis to investigate the influence of in-plane strain field on valley drifts and Berry curvatures in the monolayer MoSi$_2$N$_4$, a prototypical septuple atomic layered two-dimensional material. The low energy electron and hole valleys drift far off the K/K' point under uniaxial strains. The direction and strength of valley drift strongly depend on the nature of the charge carrier and uniaxial strain with a more substantial response along the zigzag path. Our findings are governed by the interplay between microscopic orbital contribution and symmetry lowering. The changing geometric properties of Bloch states affect the Berry curvatures and circular dichroism. Specifically, Berry curvature dipole is significantly enhanced under the tensile strain along armchair and zigzag directions. Meanwhile, the particle-hole asymmetry arising from non-equivalent electron and hole valley drifts relax the selection rules, thus reducing the degree of circular polarization up to ~0.98. Therefore, strain engineering of valley physics in the monolayer MoSi$_2$N$_4$ is of prime importance for valleytronics.

description: Introduction: This review assesses current evidence supporting dose de-escalated rituximab therapy in pemphigus vulgaris, compared to standard protocols. Primary outcome measures were remission and relapse rates. Adverse effects, cumulative steroid dosages, and serological markers of disease activity were also reported. Areas covered: A literature search was performed to look for reports describing the use of de-escalated rituximab therapy in pemphigus vulgaris. Results from heterogenous studies showed a large variation in remission and relapse rates. Complete remission rates from de-escalated treatment ranged from 41.7 to 100.0%, while rates in the control groups ranged from 60.0 to 90.9%. Relapse rates varied from 8.0 to 81.3% in the de-escalated group and from 0.0 to 72.4% in the control group. Of the 165 patients included in this report, only two major adverse effects were reported. Expert Opinion: Overall, dose de-escalated rituximab protocols reported to date appear effective and safe. However, it is unclear if treatment effect parallels that of standard regimens in regard to disease control in the long term. A lower limit of effective dosing for rituximab in pemphigus vulgaris has not yet been reached or defined. The role for and timing of repeated cycles of low-dose rituximab therapy require further exploration.

description: Finding the optimal size of deep learning models is very actual and of broad impact, especially in energy-saving schemes. Very recently, an unexpected phenomenon, the ``double descent'', has caught the attention of the deep learning community. As the model's size grows, the performance gets first worse, and then goes back to improving. It raises serious questions about the optimal model's size to maintain high generalization: the model needs to be sufficiently over-parametrized, but adding too many parameters wastes training resources. Is it possible to find, in an efficient way, the best trade-off? Our work shows that the double descent phenomenon is potentially avoidable with proper conditioning of the learning problem, but a final answer is yet to be found. We empirically observe that there is hope to dodge the double descent in complex scenarios with proper regularization, as a simple $\ell_2$ regularization is already positively contributing to such a perspective.

description: Phase transitions are ubiquitous in nature, ranging from protein folding and denaturisation, to the superconductor-insulator quantum phase transition, to the decoupling of forces in the early universe. Remarkably, phase transitions can be arranged into universality classes, where systems having unrelated microscopic physics exhibit identical scaling behaviour near the critical point. Here we present an experimental and theoretical study of the Bose-Einstein condensation phase transition of an atomic gas, focusing on one prominent universal element of phase transition dynamics: the spontaneous formation of topological defects during a quench through the transition. While the microscopic dynamics of defect formation in phase transitions are generally difficult to investigate, particularly for superfluid phase transitions, Bose-Einstein condensates (BECs) offer unique experimental and theoretical opportunities for probing such details. Although spontaneously formed vortices in the condensation transition have been previously predicted to occur, our results encompass the first experimental observations and statistical characterisation of spontaneous vortex formation in the condensation transition. Using microscopic theories that incorporate atomic interactions and quantum and thermal fluctuations of a finite-temperature Bose gas, we simulate condensation and observe vortex formation in close quantitative agreement with our experimental results. Our studies provide further understanding of the development of coherence in superfluids, and may allow for direct investigation of universal phase-transition dynamics.

description: The virtual meeting was a success. Several people told us that this was "the best virtual meeting they had seen so far", which, a year into the pandemic and without a commercial provider in the back, is a great success. The biggest point of criticism was the timing: We had programming from UTC 17:00-22:00 (evening and night in central Europe, afternoon on the US East Coast, during the day in South America and on the US West coast, but in the middle of the night for Asia and Australia). There is no good solution, but at least some variation in session time might go a long way to make it easier for all to attend at least some sessions. Feedback also indicates that the schedule was too compressed. Poster sessions and social contacts with the tool Gathertown worked out really well for all that used it. Our way of combining several services (Zoom for plenary and break-out rooms, Zenodo for uploading and viewing posters and proceedings, Google forms for registration and abstract submission, gathertown) allowed for a very low-cost meeting with little overhead (total cost: 600 $ for gathertown, zoom was provided through an institutional subscription, just 4 people on the LOC).

description: In equilibrium, the Mermin-Wagner theorem prohibits the continuous symmetry breaking for all dimensions $d\leq 2$. In this work, we discuss that this limitation can be circumvented in non-equilibrium systems driven by the spatio-temporally long-range anticorrelated noise. We first compute the lower and upper critical dimensions of the $O(n)$ model driven by the spatio-temporally correlated noise by means of the dimensional analysis. Next, we consider the spherical model, which corresponds to the large $n$ limit of the $O(n)$ model and allows us to compute the critical dimensions and critical exponents, analytically. Both results suggest that the critical dimensions increase when the noise is positively correlated in space and time, and decrease when anticorrelated. We also report that the spherical model with the correlated noise shows the hyperuniformity and giant number fluctuation even well above the critical point.

piacevole. Sempre che non ci venga l’intenzione di comprenderlo fino in fondo come Alcides Antuña Cavallero […]. Indignato per ciò che il calcio provocava nel mondo intero, il poveretto pretese di capirlo.
Vide la stessa passione negli stadi di tutto il mondo. “È un fenomeno universale” si disse. In un parco del Camerun vide un padre giocare con
suo figlio. “Contribuisce al dialogo tra generazioni” si disse. A Rio de
Janeiro vide un negro uscire da una favela e un bianco dal suo  appartamento per giocare la stessa partita sulla spiaggia di Copacabana. “È un rito di pacificazione sociale” si disse. A Monaco vide giocare con efficacia teutonica e a Siviglia verificò che anche allo stadio la gente voleva
atteggiarsi ad artista. “È un’espressione culturale come tutte le altre” si
disse. Vide due tifosi discutere di calcio, poi quattro, e poi dieci all’angolo
di una strada di Riyadh. “È un mezzo di comunicazione” si disse. Vide una pietra schiantarsi contro la testa di un arbitro a Hong Kong. “È una valvola di sfogo” si disse. Vide gli operai spendere energie dietro al pallone in un sobborgo di Buenos Aires. “È una forma di distrazione” si disse. Il calcio provocava più cose di quanto avesse immaginato, ma lui non riusciva a capire il perché e cominciava a spazientirsi. Teneva lo sguardo inchiodato sul mappamondo di suo figlio maggiore come se quel pallone pieno di paesi fosse la sintesi della sua ricerca» (Jorge Valdano, in AA.VV., 2002, pp. 5-6).

A computerized tomographic evaluation of brain morphology in first episode psychotic patients
Creators: name: Smith, Geoffrey Norman
Publisher: name: University of British Columbia

description: A growing body of computerized tomography (CT) research suggests that a significant proportion of schizophrenic patients have enlargement of the third and lateral cerebral ventricles and of the cortical sulci. Preliminary results indicate that these anomalies are present at the onset of schizophrenia and are associated with variables putatively linked to poor prognosis. Evidence of ventricular dilation in nonschizophrenic psychotic patients suggests that these morphological anomalies are not specific to the diagnosis of schizophrenia. There is much variability in the estimated prevalence of ventricular and sulcal dilation and several recent studies report no enlargement. Differences between studies in methodology, in the severity of illness of the patients, and in control group selection have been proposed as probable biases contributing to inconsistencies in the research literature. The purpose of the present study was to test a number of hypotheses suggested by the previous research. The first three predict that first episode schizophrenic and nonschizophrenic psychotic patients have 1. Enlarged lateral ventricles, 2. Enlarged third ventricle, and 3. Dilated cortical sulci. The fourth hypothesis predicts that these three brain anomalies are associated with variables putatively linked to poor prognosis (poor premorbid adjustment, negative symptoms, disrupted smooth-pursuit eye movements). The fifth hypothesis predicts that medical patients chosen from radiology records have smaller ventricles and sulci than do healthy control subjects. Measurements were taken from the CT scans of a representative sample of carefully diagnosed first episode, functionally psychotic patients. There were 31 schizophrenic, 20 schizo-phreniform, 18 bipolar, 16 depressed, three paranoid, and three schizoaffective patients. A volunteer control group of 44 healthy individuals was used for comparison. In order to evaluate possible biases due to the type of control subjects that are used, a second group comprised of 30 medical patients was obtained from radiology records. The results of this study indicate significant enlargement of the third ventricle in schizophrenic patients but failed to detect significant lateral ventricular enlargement or cortical atrophy in this patient group. No brain anomalies were found in schizophreniform, bipolar or depressed patient groups and no significant association was found between variables putatively associated with poor prognosis and any brain measure for any patient group. The third ventricle and cortical sulci were significantly smaller in the medical group than in the volunteer control group. The results are discussed in terms of the implications they have for previously reported findings and for future research. The present findings also underscore some methodological difficulties associated with using medical control subjects.

description: We reexamine different examples of reduction chains $\mathfrak{g} \supset \mathfrak{g}'$ of Lie algebras in order to show how the polynomials determining the commutant with respect to the subalgebra $\mathfrak{g}'$ leads to polynomial deformations of Lie algebras. These polynomial algebras have already been observed in various contexts, such as in the framework of superintegrable systems. Two relevant chains extensively studied in Nuclear Physics, namely the Elliott chain $\mathfrak{su}(3) \supset \mathfrak{so}(3)$ and the chain $\mathfrak{so}(5) \supset \mathfrak{su}(2) \times \mathfrak{u}(1)$ related to the Seniority model, are analyzed in detail from this perspective. We show that these two chains both lead to three-generator cubic polynomial algebras, a result that paves the way for a more systematic investigation of nuclear models in relation to polynomial structures arising from reduction chains. In order to show that the procedure is not restricted to semisimple algebras, we also study the chain $\hat{S}(3) \supset \mathfrak{sl}(2,\mathbb{R}) \times \mathfrak{so}(2)$ involving the centrally-extended Schr{ö}dinger algebra in $(3+1)$-dimensional space-time. The approach chosen to construct these polynomial algebras is based on the use of the Lie-Poisson bracket, so that all the results are presented in the Poisson (commutative) setting. The advantage of considering this approach {\it vs.} the enveloping algebras is emphasized, commenting on the main formal differences between the polynomial Poisson algebras and their noncommutative analogue. As an illustrative example of the latter, the three-generator cubic algebra associated to the Elliott chain is reformulated in the Lie algebraic (noncommutative) setting.

description: While it is commonly observed that the shape dynamics of mammalian cells can undergo large random fluctuations, theoretical models aiming at capturing cell mechanics often focus on the deterministic part of the motion. In this paper, we present a framework that couples an active gel model of the cell mechanical scaffold with the complex cell metabolic system stochastically delivering the chemical energy needed to sustain an active stress in the scaffold. Our closure assumption setting the magnitude of the fluctuations is that the chemo-mechanical free energy of the cell is controlled at a target homeostatic value. Our model rationalizes the experimental observation that the cell shape fluctuations depend on the mechanical environment that constraints the cell. We apply our framework to the simple case of a cell migrating on a one dimensional track to successfully capture the different regimes of the cell mean square displacement along the track as well as the magnitude of the long time scale effective diffusive motion of the cell.

description: Fiducial markers can encode rich information about the environment and can aid Visual SLAM (VSLAM) approaches in reconstructing maps with practical semantic information. Current marker-based VSLAM approaches mainly utilize markers for improving feature detections in low-feature environments and/or for incorporating loop closure constraints, generating only low-level geometric maps of the environment prone to inaccuracies in complex environments. To bridge this gap, this paper presents a VSLAM approach utilizing a monocular camera along with fiducial markers to generate hierarchical representations of the environment while improving the camera pose estimate. The proposed approach detects semantic entities from the surroundings, including walls, corridors, and rooms encoded within markers, and appropriately adds topological constraints among them. Experimental results on a real-world dataset collected with a robot demonstrate that the proposed approach outperforms a traditional marker-based VSLAM baseline in terms of accuracy, given the addition of new constraints while creating enhanced map representations. Furthermore, it shows satisfactory results when comparing the reconstructed map quality to the one reconstructed using a LiDAR SLAM approach.
