description: Quantum phase estimation is one of the most powerful quantum primitives. This work proposes a new approach for the problem of multiple eigenvalue estimation: Quantum Multiple Eigenvalue Gaussian filtered Search (QMEGS). QMEGS leverages the Hadamard test circuit structure and only requires simple classical postprocessing. QMEGS is the first algorithm to simultaneously satisfy the following two properties: (1) It can achieve the Heisenberg-limited scaling without relying on any spectral gap assumption. (2) With a positive energy gap and additional assumptions on the initial state, QMEGS can estimate all dominant eigenvalues to $ε$ accuracy utilizing a significantly reduced circuit depth compared to the standard quantum phase estimation algorithm. In the most favorable scenario, the maximal runtime can be reduced to as low as $\log(1/ε)$. This implies that QMEGS serves as an efficient and versatile approach, achieving the best-known results for both gapped and gapless systems. Numerical results validate the efficiency of our proposed algorithm in various regimes.

description: Using a generalisation of the detailed balance for systems maintained out of equilibrium by contact with 2 reservoirs at unequal temperatures or at unequal densities, we recover the fluctuation theorem for the large deviation funtion of the current. For large diffusive systems, we show how the large deviation funtion of the current can be computed using a simple additivity principle. The validity of this additivity principle and the occurence of phase transitions are discussed in the framework of the macroscopic fluctuation theory.

description: The aim of the research was to analyze the possibility of using mobile laser scanning systems to acquire information for production and/or updating of a basic map and to
propose a no-reference index of this accuracy assessment. Point clouds have been analyzed in terms of content of interpretation and geometric potential. For this purpose, the accuracy
of point clouds with a georeference assigned to the base map objects was examined. In order to conduct reference measurements, a geodetic network was designed and also additional
static laser scanning data has been used. The analysis of mobile laser scanning (MLS) data accuracy was conducted with the use of 395 check points. In the paper, application of the
total Error of Position of the base-map Objects acquired with the use of MLS was proposed. Research results were related to reference total station measurements. The resulting error values indicate the possibility to use an MLS point cloud in order to accurately determine
coordinates for individual objects for the purposes of standard surveying studies, e.g. for updating some elements of the base map content. Nevertheless, acquiring MLS point clouds
with satisfying accuracy not always is possible, unless specific resolution condition is fulfilled. The paper presents results of accuracy evaluation in different classes of base-map
elements and objects.

description: We present the results of a long-term high-resolution spectroscopy campaign on the O-type stars in NGC 6231. We revise the spectral classification and multiplicity of these objects and we constrain the fundamental properties of the O-star population. Almost three quarters of the O-type stars in the cluster are members of a binary system. The minimum binary fraction is 0.63, with half the O-type binaries having an orbital period of the order of a few days. The eccentricities of all the short-period binaries are revised downward, and henceforth match a normal period-eccentricity distribution. The mass-ratio distribution shows a large preference for O+OB binaries, ruling out the possibility that, in NGC 6231, the companion of an O-type star is randomly drawn from a standard IMF. Obtained from a complete and homogeneous population of O-type stars, our conclusions provide interesting observational constraints to be confronted with the formation and early-evolution theories of O stars.

Acting upon versus telling about false-beliefs : a comparison of two procedures for accessing young children's early theories of mind
Creators: name: Hala, Suzanne Marie Pauline
Publisher: name: University of British Columbia
Year: 2010

description: This report is intended to help arbitrate the unsettled matter of when in the course of their early cognitive development children first evidence some "theory-like" understanding of their own and others' mental lives. To this end, this study directly compared results obtained through the administration of two competing assessment procedures, each of which has been used to support conflicting claims regarding the earliest age at which children first evidence an understanding of the possibility of false beliefs. A substantial body of recent research has contributed to a growing, but perhaps premature consensus that children under 4 years of age do not recognize the possibility of counterfactual beliefs in others and consequently lack any early theory of mind. Much of the evidence in support of this late-onset view is based upon the use of an "unexpected change" task developed by Wimmer and Perner (1983) in which children are asked to predict where an inadequately informed story character will search for an object. In contrast to these findings results obtained using a recently developed hide-and-seek task, which directly assessed children's abilities to generate misleading clues in order to produce a false-belief in another, offered strong support for a much earlier-onset position (Chandler, Fritz & Hala, in press). Despite strong methodologic reasons in favour of accepting the results of this investigation the possibility remained that the 3-year-olds in the Chandler et al. study were a special population that might also have succeeded in the unexpected change task had they been given it. To guard against this possibility the present study provided a within-subject comparison of both the unexpected change procedure and the newer hide-and-seek procedure based on the responses of 30 children ages 3.0, 3.5 and 4.0 years. A further test of false-belief understanding was provided by asking subjects to comment directly upon their opponent's belief based on subjects' own misleading actions. As predicted even young 3-year-olds demonstrated the ability to provide misleading clues to their opponent but when faced with the unexpected change task these youngest subjects performed poorly. When responding to the false-belief question based on their own deceptive actions, however, even these youngest subjects showed strong evidence of understanding the possibility of false beliefs in others.

description: La fotografia, per sua stessa natura, racchiude in sé molteplici aspetti: è allo stesso tempo documento della realtà che rappresenta, oggetto dotato di proprie caratteristiche tecniche, espressione di una visione artistica e strumento di documentazione storica e di mediazione culturale. Nel corso del tempo la fotografia è stata chiamata a rispondere ai diversi ruoli che la caratterizzano e con l’avvento delle tecnologie digitali le sue funzioni sono state largamente potenziate. Questo contributo prende in esame questi diversi aspetti, a partire dagli archivi fotografici di supporto allo studio della storia dell’arte, passando per l’attività di catalogazione e documentazione fotografica dei beni culturali in Italia, fino alla fotografia artistica e al suo uso per le mostre virtuali. La concezione e gestione della fotografia, di cui si delineano meriti e problematiche, è analizzata anche attraverso l’analisi della sua disciplina a livello normativo e con il supporto di iniziative e buone pratiche. L’esigenza che emerge è quella di giungere ad una maggiore consapevolezza della polisemia insita nella fotografia, la cui peculiare e complessa natura può essere valorizzata efficacemente solo adottando un approccio scientifico trasversale.

Photography, for its nature, covers different aspects: it is at the same time a document of reality, an object with its own technical characteristics, an expression of artistic vision and a tool for the historical documentation and cultural mediation towards other cultural assets. Through the ages, photography responded differently to those roles and with the advent of digital technologies its functions have been extended. This contribution examines these various aspects, starting from the photographic archives supporting the study of Art History, through the activity of cataloging and the photographic documentation of cultural heritage in Italy, up to art photography and virtual exhibitions. The conception and management of photography in the modern era, their merits and problems, is studied analysing its regulations and some good practices. Furthermore, the paper highlights the need of a wider awareness of the polysemy of photography, whose peculiar and complex nature can be effectively tackled just adopting a holistic, scientific approach.

description: Dynamic analysis based on the full-system emulator QEMU is widely used for various purposes. However, it is challenging to run firmware images of embedded devices in QEMU, especially the process to boot the Linux kernel (we call this process rehosting the Linux kernel.) That's because embedded devices usually use different system-on-chips (SoCs) from multiple vendors and only a limited number of SoCs are currently supported in QEMU. In this work, we propose a technique called peripheral transplantation. The main idea is to transplant the device drivers of designated peripherals into the Linux kernel. By doing so, it can replace the peripherals in the kernel that are currently unsupported in QEMU with supported ones, thus making the Linux kernel rehostable. After that, various applications can be built upon. We implemented this technique inside a prototype system called ECMO and applied it to 815 firmware images, which consist of 20 kernel versions, 37 device models, and 24 vendors. The result shows that ECMO can successfully transplant peripherals for all the 815 Linux kernels. Among them,710 kernels can be successfully rehosted, i.e., launching a user-space shell (87.1% success rate). The failed cases are mainly because the root file system format (ramfs) is not supported by the kernel. We further build three applications, i.e., kernel crash analysis, rootkit forensic analysis, and kernel fuzzing, based on the rehosted kernels to demonstrate the usage scenarios of ECMO

description: We study gradings by abelian groups on associative algebras with involution over an arbitrary field. Of particular importance are the fine gradings (that is, those that do not admit a proper refinement), because any grading on a finite-dimensional algebra can be obtained from them via a group homomorphism (although not in a unique way). We classify up to equivalence the fine gradings on simple associative algebras with involution over the field of real numbers (or any real closed field) and, as a consequence, on the real forms of classical simple Lie algebras.

description: We study D-brane inflation in a warped conifold background that includes brane-position dependent corrections for the nonperturbative superpotential. Instead of stabilizing the volume modulus chi at instantaneous minima of the potential and studying the inflation dynamics with an effective single field (radial distance between a brane and an anti-brane) phi, we investigate the multi-field inflation scenario involving these two fields. The two-field dynamics with the potential V(phi,chi) in this model is significantly different from the effective single-field description in terms of the field phi when the field chi is integrated out. The latter picture underestimates the total number of e-foldings even by one order of magnitude. We show that a correct single-field description is provided by a field psi obtained from a rotation in the two-field space along the background trajectory. This model can give a large number of e-foldings required to solve flatness and horizon problems at the expense of fine-tunings of model parameters. We also estimate the spectra of density perturbations and show that the slow-roll parameter eta_{psi psi}=M_{pl}^2 V_{,psi psi}/V in terms of the rotated field psi determines the spectral index of scalar metric perturbations. We find that it is generally difficult to satisfy, simultaneously, both constraints of the spectral index and the COBE normalization, while the tensor to scalar ratio is sufficiently small to match with observations.

description: We present a novel graph transformer framework, HAMLET, designed to address the challenges in solving partial differential equations (PDEs) using neural networks. The framework uses graph transformers with modular input encoders to directly incorporate differential equation information into the solution process. This modularity enhances parameter correspondence control, making HAMLET adaptable to PDEs of arbitrary geometries and varied input formats. Notably, HAMLET scales effectively with increasing data complexity and noise, showcasing its robustness. HAMLET is not just tailored to a single type of physical simulation, but can be applied across various domains. Moreover, it boosts model resilience and performance, especially in scenarios with limited data. We demonstrate, through extensive experiments, that our framework is capable of outperforming current techniques for PDEs.

A trial reading of Robert Browning's The Ring and the Book
Creators: name: Hines, Susan C.
Publisher: name: University of British Columbia
Year: 2010

description: The following study focuses on the allegorical import of the trial in Robert Browning's long poem, The Ring and the Book; borrowing from various theories in phenomenological and rhetorical criticism and from recent legal research in jury dynamics, it develops the idea that a reader's autonomous response to this particular text may be a deceptive illusion. Like jury members, Browning's audience is asked to determine the truth of a specific incident and to deliberate on the guilt or innocence of the monologists who appear before them. However, prone to the rhetoric of inconsequential hearsay, highly emotional testimony and persuasive legal exposition, readers are inclined to make the same errors of perception as jurors who tend to judge persons by their performances rather than by the evidence presented. In a discussion that moves from the rhetorical effects of Browning's legal metaphor to the philosophical ramifications of the authority by which literary and legal interpretations are canonized, this essay highlights the aesthetic and ethical similarities between the work of the poet, the lawmaker, and the reader. That agents involved in producing this story—the poet, the lawyers, and The Ring and the Book's many readers—must rationalize the facts of the case and piece together information so that the story-line is logical and coherent, is both a reconstructive and a recreative activity; for where the facts themselves provide few answers, where gaps appear in the text, the onus is on the interpreter to "fill out" the narrative. So, all judgment is, in effect, the result of a highly tenuous process which is hardly clear cut By emphasizing the burden of judgment in his poem, Browning succeeds at making his readers only too aware of their potential misjudgments. And, by forcing his audience into the position of a jury, he demonstrates how any trial may well be a mis-trial.

description: The Traditional Approximation of Rotation (TAR) is a treatment of the hydrodynamic equations of rotating and stably stratified fluids in which the action of the Coriolis acceleration along the direction of the entropy and chemical stratifications is neglected because it is weak in comparison with the buoyancy force. The dependent variables in the equations for the dynamics of gravito-inertial waves (GIWs) then become separable into radial and horizontal parts as in the non-rotating case. The TAR is built on the assumptions that the star is spherical (i.e. its centrifugal deformation is neglected) and uniformly rotating. We study the feasibility of carrying out a generalisation of the TAR to account for the centrifugal acceleration in the case of strongly deformed uniformly and rapidly rotating stars (and planets), and to identify the validity domain of this approximation. We built analytically a complete formalism that allows the study of the dynamics of GIWs in spheroidal coordinates which take into account the flattening of rapidly rotating stars by assuming the hierarchies of frequencies adopted within the TAR in the spherical case and by deriving a generalised Laplace tidal equation for the horizontal eigenfunctions of the GIWs and their asymptotic wave periods, which can be used to probe the structure and dynamics of rotating deformed stars with asteroseismology. Using 2D ESTER stellar models, we determine the validity domain of the generalised TAR as a function of the rotation rate of the star normalised by its critical angular velocity and its pseudo-radius. This generalisation allows us to study the signature of the centrifugal effects on GIWs in rapidly rotating deformed stars. We found that the effects of the centrifugal acceleration in rapidly rotating early-type stars on GIWs are theoretically detectable in modern space photometry using observations from Kepler.

One of the main goals of this project is to build a distributed database of lung CT scans in order to enable automated image analysis through a data and cpu GRID infrastructure. The basic modules of our lung-CAD system, a dot-enhancement filter for nodule candidate selection and a neural classifier for false-positive finding reduction, are described. The system was designed and tested for both internal and sub-pleural nodules. The results obtained on the collected database of low-dose thin-slice CT scans are shown in terms of free response receiver operating characteristic (FROC) curves and discussed.

description: We experimentally investigate the evolution of spatial phase correlations in a rapidly quenched inhomogeneous Bose gas of rubidium using off-resonant matter-wave interferometry. We measure the phase coherence length $\ell$ of the sample and directly probe its increase during the early stage of condensate growth before vortices are formed. Once the vortices are formed stably in the quenched condensate, the measured value of $\ell$ is shown to be linearly proportional to the mean distance between the vortex. These results confirm the presence of phase coarsening prior to vortex formation, which is crucial for a quantitative understanding of the resultant defect density in samples undergoing critical phase transitions.

Classification algorithms for Intelligent Transport Systems

description: Intelligent Transport Systems (ITS) consists in the application of ICT to transport to offer new and improved services to the mobility of people and freights. While
using ITS, travellers produce large quantities of data that can be collected and analysed to study their behaviour and to provide information to decision makers and
planners. The thesis proposes innovative deployments of classification algorithms for Intelligent Transport System with the aim to support the decisions on traffic
rerouting, bus transport demand and behaviour of two wheelers vehicles. The first part of this work provides an overview and a classification of a selection
of clustering algorithms that can be implemented for the analysis of ITS data.
The first contribution of this thesis is an innovative use of the agglomerative hierarchical clustering algorithm to classify similar travels in terms of their origin and destination, together with the proposal for a methodology to analyse drivers’ route choice behaviour using GPS coordinates and optimal alternatives. The clusters
of repetitive travels made by a sample of drivers are then analysed to compare observed route choices to the modelled alternatives. The results of the analysis show that drivers select routes that are more reliable but that are more expensive in terms of travel time. Successively, different types of users of a service that provides information on the real time arrivals of bus at stop are classified using Support Vector Machines. The results shows that the results of the classification of different types of bus transport users can be used to update or complement the census on
bus transport flows. Finally, the problem of the classification of accidents made by two wheelers vehicles is presented together with possible future application of
clustering methodologies aimed at identifying and classifying the different types of accidents.

description: Ultra-light dark matter perturbs the orbital motion of binary pulsars, in particular by causing peculiar time variations of a binary's orbital parameters, which then induce variations in the pulses' times-of-arrival. Binary pulsars have therefore been shown to be promising detectors of ultra-light dark matter. To date, the sensitivity of binary pulsars to ultra-light dark matter has only been studied for dark matter masses in a narrow resonance band around a multiple of the binary pulsar orbital frequency. In this study we devise a two-step, bayesian method that enables us to compute semi-analytically the sensitivity for all masses, also away from the resonance, and to combine several observed binaries into one global sensitivity curve. We then apply our method to the case of a universal, linearly-coupled, scalar ultra-light dark matter. We find that with next-generation radio observatories the sensitivity to the ultra-light dark matter coupling will surpass that of solar-system constraints for a decade in mass around $m\sim10^{-21}$ $\text{eV}$, even beyond resonance.

description: We study covariant equations in quantum cosmology of an extended minisuperspace obtained by the Eisenhart--Duval lift. We find that a Dirac-type equation is naturally introduced in the extended minisuperspace. Explicit forms of the fundamental solutions are yielded for specific models.

STOP-IT Computer Vision Tool: Automatic identification of abnormal behavior
Creators: name: Bakalos, Nikolaos
Publisher: name: Zenodo
Year: 2019
Subjects: COMPUTER VISION, network of cameras, behaviour classification,

description: The Coordinated Network of Cameras tool is based on a Deep-Non-linear Auto-Regressive Moving Average (Deep-NARMA) filter that leverages the representational capabilities of Convolutional Neural Networks (CNN), properly modified to cope with the autoregressive nature of a tapped delay line, and transforms the inputs in an efficient non-linear feature map. The proposed classifier achieves an effective feature representation of the heterogeneous inputs but it simultaneously introduces an input-and output memory. We also propose a novel data fusion processing of different modalities to improve the detection accuracy of unusual behavior. Specifically, alongside the normal RGB surveillance, we can also leverage thermal imaging.

description: Generally, gross errors exist in observations, and they affect the accuracy of
results. We review methods to detect the gross errors by Robust estimation method based
on L1-estimation theory and their validity in adjustment of geodetic networks with different
condition. In order to detect the gross errors, we transform the weight of accidental model
into equivalent one using not standardized residual but residual of observation, and apply
this method to adjustment computation of triangulation network, traverse network, satellite
geodetic network and so on. In triangulation network, we use a method of transforming
into equivalent weight by residual and detect gross error in parameter adjustment without
and with condition. The result from proposed method is compared with the one from using
standardized residual as equivalent weight. In traverse network, we decide the weight by
Helmert variance component estimation, and then detect gross errors and compare by the
same way with triangulation network In satellite geodetic network in which observations
are correlated, we detect gross errors transforming into equivalent correlation matrix by
residual and variance inflation factor and the result is also compared with the result from
using standardized residual. The results of detection are shown that it is more convenient
and effective to detect gross errors by residual in geodetic network adjustment of various
forms than detection by standardized residual.

description: Il presente lavoro ha l’obiettivo di analizzare due tele conservate nella chiesa di Santa Chiara a Montelupone (Macerata), chiusa al pubblico in seguito al terremoto del 2016. Si tratta di una copia dell’Annunciazione di Federico Barocci già nella cappella dei duchi di Urbino del santuario di Loreto, per la quale si  è cercato di capire il rapporto con le altre copie o derivazioni della bottega del pittore di Urbino, e della pala dell'altare maggiore della chiesa, raffigurante una Madonna con Bambino e santi attribuita al pittore messinese Onofrio Gabrieli per via della firma: in questo caso il dipinto è stato inserito nel percorso del maestro siciliano, figura dalla carriera itinerante, di cui la tela marchigiana costituisce un ennesimo tassello.

The following work aims to analyze two paintings preserved in the church of Santa Chiara in Montelupone (Macerata), still closed to the public following the earthquake of 2016. It is about a copy of the Annunciation by Federico Barocci, yet in the chapel of dukes of Urbino in the sanctuary of Loreto, for which we tried to understand the relationship with the other copies or derivation from the shop of the painter of Urbino, and the altarpiece of the church, depicting a Madonna with Child and Saints attributed to Onofrio Gabrieli because of his signature: in this case the work of art has been inserted in the Sicilian master’s path, person with a traveling career, which the canvas for Marche is yet another piece.

description: MOTIVATION: Over the past 50 years, our ability to model protein sequences with evolutionary information has progressed in leaps and bounds. However, even with the latest deep learning methods, the modelling of a critically important class of proteins, single orphan sequences, remains unsolved. RESULTS: By taking a bioinformatics approach to semi-supervised machine learning, we develop Profile Augmentation of Single Sequences (PASS), a simple but powerful framework for building accurate single-sequence methods. To demonstrate the effectiveness of PASS we apply it to the mature field of secondary structure prediction. In doing so we develop S4PRED, the successor to the open-source PSIPRED-Single method, which achieves an unprecedented Q3 score of 75.3% on the standard CB513 test. PASS provides a blueprint for the development of a new generation of predictive methods, advancing our ability to model individual protein sequences. AVAILABILITY: The S4PRED model is available as open source software on the PSIPRED GitHub repository (https://github.com/psipred/s4pred), along with documentation. It will also be provided as a part of the PSIPRED web service (http://bioinf.cs.ucl.ac.uk/psipred/). SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

description: We study both analytically and numerically the gravitational fields of stars in f(R) gravity theories. We derive the generalized Tolman-Oppenheimer-Volkov equations for these theories and show that in metric f(R) models the Parameterized Post-Newtonian parameter $γ_{\rm PPN} = 1/2$ is a robust outcome for a large class of boundary conditions set at the center of the star. This result is also unchanged by introduction of dark matter in the Solar System. We find also a class of solutions with $γ_{\rm PPN} \approx 1$ in the metric $f(R)=R-μ^4/R$ model, but these solutions turn out to be unstable and decay in time. On the other hand, the Palatini version of the theory is found to satisfy the Solar System constraints. We also consider compact stars in the Palatini formalism, and show that these models are not inconsistent with polytropic equations of state. Finally, we comment on the equivalence between f(R) gravity and scalar-tensor theories and show that many interesting Palatini f(R) gravity models can not be understood as a limiting case of a Jordan-Brans-Dicke theory with $ω\to -3/2$.

description: In this article, the classification of underground space types is analyzed. It is established that there are objects that are taxed in the tax code of Ukraine and there are
those that are not taxed. The results of the research are justified by the lack of mechanisms and technical solutions of three-dimensional objects of commercial space taxation, which
have been intensively developing in Ukraine. The ways of solving legal conflicts regarding registration and taxation of real estate objects are suggested. Based on the study of the
legislative base and normative legal documents in the sphere of land relations, a classifier of three-dimensional space objects, which today are fully or partially used for commercial
purposes in various types of economic activity has been proposed. The analysis of the regulatory and legal framework regarding the taxation of underground space facilities has been
carried out. Objects for which the taxation of land is charged and those objects for which there is no charge for the use of underground space have been identified. A methodology
for the justified calculation of a decreasing percentage ratio for calculating a normative monetary evaluation (NME) is developed for the cases where the object of an underground
commercial space is located at a distance from the center in one of the proposed zones.
Alcune pale d'altare cinque e seicentesche nella chiesa di San Francesco a Fermo / Some 16th and 17th century altarpieces in the church of San Francesco in Fermo

description: L’articolo prende in esame quattro pale d’altare della chiesa di San Francesco a Fermo, accomunate dal fatto di essere state quasi del tutto trascurate dalla storiografia. Un confronto con opere di Lorenzo Lotto e Antonio Liberi da Faenza evidenzia i punti di tangenza con la coeva cultura figurativa veneto-romagnola. Si presentano poi alcuni dipinti, conservati ad Ascoli e a Monteprandone, che per la cifra stilistica sembrano da legare allo stesso ignoto autore delle tele fermane. Nel secondo paragrafo si approfondiscono le circostanze relative alla committenza di due pale d’altare del Seicento, la Madonna col Bambino e i santi Antonio Abate e Maria Maddalena, firmata da Gaspare Celio, e una Immacolata Concezione tra santi, attribuita al pittore romano Benigno Vangelini. Si sottolinea inoltre il forte messaggio, sia religioso che civico, espresso da tali opere.

This essay examines four altarpieces from the church of San Francesco in Fermo with the common feature that they’ve been almost neglected by the local historiography. A comparison with some paintings of Lorenzo Lotto and Antonio Liberi da Faenza highlights on the agreement with a Venetian figurative language inflected by the culture of Romagna. Some paintings from Ascoli and Monteprandone are then presented because of their style that links them to the same unknown author of the paintings from Fermo. The second paragraph sets out the context of two 17th century altarpieces’ patronage: a Madonna and child with saints Antonio Abate e Maria Maddalena, signed by Gaspare Celio, and an Immaculate Conception with saints, attributed to the Roman painter Benigno Vangelini. For both the paintings, the strong message, religious and civic together, is underlined.

description: We implement coherent delocalization as a tool for improving the two primary metrics of atomic clock performance: systematic uncertainty and instability. By decreasing atomic density with coherent delocalization, we suppress cold-collision shifts and two-body losses. Atom loss attributed to Landau-Zener tunneling in the ground lattice band would compromise coherent delocalization at low trap depths for our $^{171}$Yb atoms; hence, we implement for the first time delocalization in excited lattice bands. Doing so increases the spatial distribution of atoms trapped in the vertically-oriented optical lattice by $\sim7$ times. At the same time we observe a reduction of the cold-collision shift by 6.5(8) times, while also making inelastic two-body loss negligible. With these advantages, we measure the trap-light-induced quenching rate and natural lifetime of the ${}^3$P${}_0$ excited-state as $5.7(7)\times10^{-4}$ $E_r^{-1}s^{-1}$ and 19(2) s, respectively.
