description: Cette séance aura pour objet l’Annuaire des Allemands à Paris de 1854, un « bottin du commerce » compilant un total de 4 772 adresses de particuliers et d’entreprises germaniques domiciliés à Paris et dans sa banlieue en 1854. Elle s’intéressera à la base de données créée par l’Institut historique allemand et aux visualisations de ces données sur un plan historique de Paris. Nous focaliserons notre intervention sur le quartier Richelieu, un des fiefs de l’immigration allemande au XIXe siècle, largement oubliée aujourd’hui. Intervenants

 Le séminaire lié au programme de recherche « Richelieu. Histoire du quartier » explore les méthodes de recherche mises en œuvre dans l’étude d’un quartier, d’une rue ou d’un bâtiment. En 2018-2019 a été réalisé l’état des lieux des principaux éléments ayant façonné ce secteur au fil des siècles. Puis, en 2021-2022, son histoire urbaine, architecturale, sociale, économique et culturelle sur un large XIXe siècle a été documentée par l’analyse de corpus iconographiques hétérogènes. Pour ce troisième cycle, les intervenants poursuivent ces réflexions en interrogeant des cas d’étude mêlant travaux historiques et pratiques numériques. Il s’agit de croiser et questionner les pratiques propres à la rencontre entre ces disciplines. Cartographie, photogrammétrie et modélisation fournissent des outils d’exposition de l’iconographie et de clarification des problématiques qu’elle soulève. Constitutif de certains courants, comme le spatial turn, l’espace urbain et architectural est aussi abordé dans ses usages par la société, et à travers les réseaux qui en sous-tendent les transformations. Ce dialogue interdisciplinaire ouvre des perspectives d’exploitation, d’exposition et de pérennisation des sources. En partenariat avec l’École nationale des chartes (ENC), le Centre allemand d’histoire de l’art (DFK Paris), la Bibliothèque nationale de France (BnF), l’École polytechnique fédérale de Lausanne (EPFL), le Centre André Chastel, et avec le soutien de la Banque de France et de la Fondation des sciences du patrimoine (FSP)

description: Greenberger-Horne-Zeilinger (GHZ) paradox provides an all-versus-nothing test for the quantum nonlocality. In all the GHZ paradoxes known so far each observer is allowed to measure only two alternative observables. Here we shall present a general construction for GHZ paradoxes in which each observer measuring more than two observables given that the system is prepared in the $n$-qudit GHZ state. By doing so we are able to construct a multi-setting GHZ paradox for the $n$-qubit GHZ state, with $n$ being arbitrary, that is genuine $n$-partite, i.e., no GHZ paradox exists when restrict to a subset of number of observers for a given set of Mermin observables. Our result fills up the gap of the absence of a genuine GHZ paradox for the GHZ state of an even number of qubits, especially the four-qubit GHZ state as used in GHZ's original proposal.

Two HW-manifolds M_1 and M_2 are cohomological rigid if and only if a homeomorphism between M_1 and M_2 is equivalent to an isomorphism of graded rings H^{*}(M_1,F_2) and H^{*}(M_2,F_2). We prove that HW-manifolds are cohomological rigid.

description: We consider the probability for a colour-singlet qqbar pair to emit a gluon, in strongly and smoothly ordered antenna showers. We expand to second order in alphaS and compare to the second-order QCD matrix elements for Z -> 3 jets, neglecting terms suppressed by 1/NC^2. We give a prescription that corrects the shower to the matrix-element result at this order for both soft and hard emissions, thereby explicitly reducing its dependence on evolution- and renormalization-scale choices. We confirm that the choice of pT for both of these scales absorbs all logarithms through order alphaS^2, and contrast this with various alternatives. We include these corrections in the VINCIA shower generator and study the impact on LEP event-shape and fragmentation observables. An uncertainty estimate is provided for each event, in the form of a vector of alternative weights.

description: The dynamics of Quark-gluon plasma (QGP) as a lump of deconfined free quarks and gluons is elaborated. Based on the first principal we construct the Lagrangian that represents the dynamics of QGP. To induce a hydrodynamics approach, we substitute the gluon fields with flow fields. As a result, the derived equation of Motion (E.O.M) for gluon dominated QGP shows the form that similar to Euler equation, and the energy momentum tensor also represents explicitly the system of ideal fluid. Combining the E.O.M and energy momentum tensor, the pressure and energy density distribution as the equation of states are analytically derived.

description: N=4 Poincare supergravity has a global SU(1,1) duality symmetry that acts manifestly only on shell as it involves duality rotations of vector fields. A U(1) subgroup of this symmetry is known to be anomalous at the quantum level in the presence of a non-trivial gravitational background. We first derive this anomaly from a novel perspective, by relating it to a similar anomaly in conformal supergravity where SU(1,1) acts off shell, using the fact that N=4 Poincare supergravity has a superconformal formulation. We explicitly construct the corresponding local and nonlocal anomalous terms in the one-loop effective action. We then study how this anomaly is reflected in the supergravity S-matrix. Calculating one-loop N=4 supergravity scattering amplitudes (with and without additional matter multiplets) using color/kinematics duality and the double-copy construction we find that a particular U(1) symmetry which was present in the tree-level amplitudes is broken at the quantum level. This breaking manifests itself in the appearance of new one-loop N=4 supergravity amplitudes that have non-vanishing soft-scalar limits (these amplitudes are absent in N>4 supergravities). We discuss the relation between these symmetry-violating amplitudes and the corresponding U(1) anomalous term in the one-loop supergravity effective action.

A sub-ensemble theory of ideal quantum measurement processes

description: To elucidate ideal measurements, one must explain how individual events emerge from quantum theory which deals with statistical ensembles, and how different may end up with different final states. This so-called "measurement problem" is tackled with two guidelines. On the one hand, the dynamics of the macroscopic apparatus A coupled to the tested system S is described mathematically within a standard quantum formalism, where "q-probablities" remain devoid of interpretation. On the other hand, interpretative principles are introduced to account for the expected features of ideal measurements. Most of the five principles, which relate the quantum formalism to physical reality, are straightforward and refer to macroscopic variables. The process can be identified with a relaxation of S+A to thermodynamic equilibrium, not only for a large ensemble $\scriptE$ of runs but even for its sub-ensembles. The different mechanisms of quantum statistical dynamics that ensure the relaxation are exhibited. The additional information provided by the sub-ensembles remove Schrödinger's quantum ambiguity of the final density operator for $\scriptE$ which hinders its direct interpretation, and bring out a commutative behaviour of the pointer observable at the final time. The latter property supports the introduction of a last principle, needed to switch from the statistical ensembles and sub-ensembles described by quantum theory to individual experimental events. It amounts to identify some formal "q-probabilities" with ordinary frequencies, but only those which refer to the final pointer indications. The desired properties of ideal measurements, in particular the uniqueness of the result for each individual run and von Neumann's reduction, are thereby recovered with economic interpretations. The status of Born's rule involving both A and S is re-evaluated, and contextuality is made obvious.

Energy spectrum of black holes : a new view
Creators: name: Majhi, Abhishek
Publisher: name: arXiv
Year: 2013
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Energy of a black hole is usually quantized by invoking some area quantization scheme after expressing the energy in terms of the horizon area. However, in this approach one has to quantize the local and asymptotic energy of the black hole separately and the two results do not manifest any physical correspondence with each other. Here, as opposed to this practice, we find the unique energy spectrum of black holes by adopting a top-down approach. The physical links among the underlying quantum theory, statistical mechanics and thermodynamics of the black hole horizon play the central role in determining the energy spectrum. The energy spectrum that we obtain, explicitly reveals the correspondence between asymptotic and local observations through the presence of the surface gravity of the horizon as a parameter in the spectrum, rather than being expressed as a function of area and consequently getting quantized in the usual approach. Thus, our result presents a new view as far as black hole energy quantization is concerned. The calculations are performed using the quantum geometric description of black hole horizons as laid down by loop quantum gravity.

There are some new results. In particular, we give new "colorful" extensions of the max-min Caratheodory theorem. In the end of the paper, we list some consequences of the topological Radon and Tverberg theorems (like Helly and Centerpoint theorems), valid over a more general class of max-T semirings, where multiplication is a triangular norm.

description: A universal schema for diagonalization was popularized by N. S. Yanofsky (2003) in which the existence of a (diagonolized-out and contradictory) object implies the existence of a fixed-point for a certain function. It was shown that many self-referential paradoxes and diagonally proved theorems can fit in that schema. Here, we fit more theorems in the universal schema of diagonalization, such as Euclid's theorem on the infinitude of the primes and new proofs of Boolos (1997) for Cantor's theorem on the non-equinumerosity of a set with its powerset. Then, in Linear Temporal Logic, we show the non-existence of a fixed-point in this logic whose proof resembles the argument of Yablo's paradox. Thus, Yablo's paradox turns for the first time into a genuine mathematico-logical theorem in the framework of Linear Temporal Logic. Again the diagonal schema of the paper is used in this proof, and also it is shown that G. Priest's inclosure schema (1997) can fit in our universal diagonal/fixed-point schema. We also show the existence of dominating (Ackermann-like) functions (which dominate a given countable set of functions---like primitive recursives) using the schema.

Evaluation of the Impact of Financial Sector Reforms on Stock Market Efficiency: The Case of Egypt
Creators: name: Saleh, Mohamed
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Financial economics

description: This thesis aims at contributing to the literature on the Egyptian stock market efficiency by empirically conducting a financial sector reforms impact assessment on the efficiency of the stock market at large as measured by the main index issued by the Egyptian Exchange, and on individual stocks that were impacted with stock market specific reforms at one point of time. Efficiency parameter estimates are conducted on a time-varying basis stemming from the believe that stock markets evolve through time, and so does the level of efficiency. The adopted statistical techniques utilized the Kalman Filters technique to obtain the time-varying efficiency parameters for the autoregressive model at the market and individual stocks level. Other deterministic models would have only resulted in a single point estimate for efficiency which does not render assessing the time-varying impact of reforms on efficiency feasible. The positivism philosophy and a deductive approach has been adopted based on the statistical nature of this research and the well-grounded theories covering the stock markets efficiency. The financial sector reforms are presented with specific focus on capital markets reforms. Proxy variables have been constructed to capture reforms, with some of those reforms impact being tested on the market level, and others on individual stocks level. The proxy variables construction is based on the trading data obtained from the Egyptian Exchange after segregating the data in such a manner to construct proxy variables that reflects the different reforms, and on the dates of introducing the reform measures. Ranking the reforms impact on the time-varying efficiency parameter indicated that the implemented financial sector reform program, per se, had the biggest impact on improving the efficiency on the market level, the free float percent to be of a significant positive impact when assessed on both, individual stocks and the market. Another important factor is the presence of wide circuit breakers and price limits for traded securities. The wider the price limits, the greater the positive impact on price efficiency. Most of the proxy variables yielded results conforming with the prior expectations regarding its impact on the time varying efficiency, apart from few on the market and on the individual stocks levels. Reforms’ ranking provides guidance to designing future reform plans as it shows the positive impact of having a clearly identified and announced reform plan, the importance of market depth reforms as represented by the free float of companies, the necessity of not having hindrances for the price adjustment mechanisms, and the importance of having sizable offerings to the public. Liquidity enhancement reforms such as the same-day trading had a positive impact on efficiency on the market level, albeit with a smaller magnitude.
Constructing numerically stable Kalman filter-based algorithms for gradient-based adaptive filtering

description: This paper addresses the numerical aspects of adaptive filtering (AF) techniques for simultaneous state and parameters estimation arising in the design of dynamic positioning systems in many areas of research. The AF schemes consist of a recursive optimization procedure to identify the uncertain system parameters by minimizing an appropriate defined performance index and the application of the Kalman filter (KF) for dynamic positioning purpose. The use of gradient-based optimization methods in the AF computational schemes yields to a set of the filter sensitivity equations and a set of matrix Riccati-type sensitivity equations. The filter sensitivities evaluation is usually done by the conventional KF, which is known to be numerically unstable, and its derivatives with respect to unknown system parameters. Recently, a novel square-root approach for the gradient-based AF by the method of the maximum likelihood has been proposed. In this paper, we show that various square-root AF schemes can be derived from only two main theoretical results. This elegant and simple computational technique replaces the standard methodology based on direct differentiation of the conventional KF equations (with their inherent numerical instability) by advanced square-root filters (and its derivatives as well). As a result, it improves the robustness of the computations against roundoff errors and leads to accurate variants of the gradient-based AFs. Additionally, such methods are ideal for simultaneous state estimation and parameter identification since all values are computed in parallel. The numerical experiments are given.

In this paper we describe minimal binomial generating sets of $I_L$ and their invariants. We use as a main tool a graph construction on equivalence classes of fibers of $I_L$. As one application of the theory developed we characterize binomial complete intersection lattice ideals, a longstanding open problem in the case of non-positive lattices.

description: This research explores the association between various levels of Public-Client Participation (PCP) and the efficiency of Asset Delivery Performance (ADP) in terms of impact on the success of PPP+ infrastructure delivery performance in Kuwait by means of the utilisation of public client guidance. The risk and equity levels of PCP were found to be the dominant factors that have an influence on delivery performance, although the cost and time taken for ADP was an early indicator of the overall performance of the PPP+. The investigation into the provision of the PPP+ infrastructure encompassed various implementations of the integrated schemes, including PPP, BOT, BOOT, and DB. The literature review identified that there had, to date, only been limited research focusing solely on PCP and success with PPP+. An investigation was made into how the public-client relationship could be more effectively involved in decision-making in the early stages of PPP+. The current inefficient performance delivery of PPP+ schemes in Kuwait indicated the need to explore the ways in which the efficiency of asset delivery was affected by the various levels of PCP which were incorporated into public-client guidance. As both cost and time were found to have a significant impact on ADP, providing an early indication of the eventual overall performance delivery, a quantitative method was therefore applied to establish the relationship between these two determinants. A total of 415 data points was collected from public and private sector participants in Kuwait. The results showed a significant correlation between the risk and equity of PCP and the cost and time of ADP in PPP projects. This offered a structural basis for a model framework and the resulting logistic regression framework was designed as ΔC and ΔT 3D models to represent the complexity of the interrelated variables. In addition, ΔC and ΔT 2D models were extracted from this original model to produce a more targeted public-client guidance in PPP. The illustration of such practical solutions, in terms of public-client guidance, could benefit key decision makers, enhance and encourage the participation of the private sector and the implementation of PPP scheme in Kuwait.

description: The thesis concerns the analysis of the Active Galactic Nuclei. These are galaxies with an active core. The most luminous type of Active Galactic Nuclei is Quasar. It contains the supermassive black hole at the center. One of the least known subtype of Quasars are: Weak emission-Line Quasars. Their recognizable feature are weak emission-lines. The primary goal of PhD thesis is to evaluate the global parameters such as: the black hole mass, the accretion rate, spin of the black hole, and the inclination of weak emission-line quasars based on the continuum fit method. This method apart from the literature black hole masses estimation methods does not depend on the observed Full Width at Half Maximum of emission line, which could be biased due to the weakness or lack of the emission lines in these quasars. Using the Spectral Energy Distribution of quasars, I have fitted the geometrically thin and optically thick accretion disk model described by Novikov \& Thorne equations. I have obtained the model of the continuum of the accretion disk for the 10 weak emission-line quasars. The second project concerned the description of abnormal, deep absorption of SDSS J110511.15+530806.5 quasar. I checked the correctness of the thesis posed that corona and warm skin concept above/around an accretion disk explain this phenomenon.

description: It is generally believed that the resolution in digital holography is limited by the size of the captured holographic record. Here, we present a method to circumvent this limit by self-extrapolating experimental holograms beyond the area that is actually captured. This is done by first padding the surroundings of the hologram and then conducting an iterative reconstruction procedure. The wavefront beyond the experimentally detected area is thus retrieved and the hologram reconstruction shows enhanced resolution. To demonstrate the power of this concept, we apply it to simulated as well as experimental holograms.

description: Στην παρούσα εργασία πραγματοποιήθηκαν πειράματα στηλών με σκοπό τη μελέτη της κινητικότητας βαρέων μετάλλων σε εδάφη με προσθήκη βιοεξανθρακωμάτων (biochars).Οι πρώτες ύλες που χρησιμοποιήθηκαν για την παρασκευή των biochars προήλθαν από λυματολάσπη που συλλέχθηκε από τις ταινιοφιλτρόπρεσσες του βιολογικού καθαρισμού Χανίων, από το οργανικό κλάσμα απορριμμάτων που παρελήφθη από την ΔΕΔΙΣΑ, καθώς και από φλοιούς ρυζιού από ριζόμυλο της περιοχής Θεσσαλονίκης.
Πιο συγκεκριμένα στον πρώτο κύκλο πραγματοποιήθηκαν πειράματα εκρόφησης με τέσσερα πληρωτικά μέσα (έδαφος χωρίς προσθήκες, έδαφος με biochar απο λυματολάσπη, έδαφος με biochar από το οργανικό κλάσμα των απορριμμάτων, έδαφος με biochar από φλοιούς ρυζιού). Τα μέταλλα που εξετάστηκαν σε αυτή την φάση ήταν το Cr(III), το Cr(VI)και το Аs(V). Η διαβροχή των στηλών επιλέχτηκε έτσι ώστε να ανταποκρίνεται σε μια ρεαλιστική βροχόπτωση για την περιοχή των Χανίων και εν συνεχεία ελήφθησαν δείγματα που μετρήθηκαν στην ατομική απορρόφηση για να προσδιοριστούν οι συγκεντρώσεις των προς μελέτη βαρέων μετάλλων. Από τα αποτελέσματα συμπεραίνουμε ότι το έδαφος έδειξε μια αρκετά καλή συμπεριφορά στη συγκράτηση των βαρέων μετάλλων και ότι η προσθήκη των biochars άλλοτε βελτίωσε και άλλοτε όχι την προσροφητική ικανότητα του εδάφους. Έτσι για παράδειγμα, στην περίπτωση του Cr(III),ενώ το έδαφος χωρίς προσθήκες εκρόφησε 1,5% της συνολικής ποσότητας του Cr (III), στη στήλη με χώμα και biochar από φλοιούς ρυζιού εκροφήθηκε συνολικά  2,7%. Για τις στήλες με biochar από το οργανικό κλάσμα των απορριμμάτων και τη λάσπη τα αντίστοιχα ποσοστά ήταν 1% και 0,5%.
Στον δεύτερο κύκλο πειραμάτων επιλέχτηκαν τρία πληρωτικά μέσα: χώμα χωρίς προσθήκες, χώμα και biochar από φλοιούς ρυζιού, χώμα και biochar από λυματολάσπη. Ετοιμάστηκαν διαλύματα Cr(VI)με συγκεντρώσεις 1mg/L, 3mg/Lκαι 10mg/L, τα οποία χρησιμοποιήθηκαν για τη διαβροχή των στηλών σε κάθε σετ πειραμάτων. Το άλας που χρησιμοποιήθηκε ήταν το K2CrO4. Από τα διαγράμματα που προέκυψαν διαπιστώνουμε ότι η επίτευξη συνθηκών πλήρους διαρροής στο δεδομένο χρόνο διαβροχής συμβαίνει μόνο για την περίπτωση των υψηλών συγκεντρώσεων (10mg/l, 3mg/l).

description: The present study aimed to explore the quantitative effects of sodium-glucose cotransporter-2 (SGLT-2) inhibitors on liver functions in patients with nonalcoholic fatty liver disease (NAFLD). A total of 4771 patients with NAFLD were included for analysis by means of nonlinear mixed effect modeling, where the change rates of liver functions were taken as the evaluation indexes so as to eliminate the potential baseline effects. For ALT and AST, the Emax of SGLT-2 inhibitors was −17.8% and −13.9%, respectively, and the ET50 was 6.86 weeks and 10 weeks, respectively. Furthermore, the duration time to achieve 25%, 50%, 75%, and 80% Emax were 2.3 weeks, 6.86 weeks, 20.6 weeks, 27.5 weeks in ALT, 3.4 weeks, 10 weeks, 30 weeks, 40 weeks in AST, respectively. Thus, to realize the plateau period (80% of Emax) of SGLT-2 inhibitors on ALT and AST in patients with NAFLD, 100 mg/day canagliflozin (or 10 mg/day dapagliflozin or 10 mg/day empagliflozin) needs to be taken for 20.6 weeks and 30 weeks, respectively. The present study explored the quantitative effects of SGLT-2 inhibitors on liver functions and recommends a therapeutic regimen in patients with NAFLD.

description: Μεγάλες ποσότητες πλαστικών καταλήγουν στα οικοσυστήματα κάθε χρόνο, είτε με τη μορφή απορριμμένων ή χαμένων αντικειμένων, είτε σαν διαρροές από ΧΥΤΑ ή μονάδες παραγωγής πλαστικών, με αποτέλεσμα να συσσωρεύονται, έχοντας αρνητικές συνέπειες για τη θαλάσσια ζωή. Τα μικροπλαστικά εισέρχονται στο περιβάλλον αυτοτελή αντικείμενα, όπως τα pellets, ή σαν αποτέλεσμα κατάτμησης μεγαλύτερων αντικειμένων.
Για την πραγματοποίηση της εργασίας αυτής, μέσα σε διάστημα 3 μηνών συγκεντρώθηκαν, μετά από κοσκίνισμα, δείγματα εκβρασμένων τμημάτων πλαστικών αντικειμένων και πλαστικών pellets παραγωγής από την επιφάνεια και από βάθος υποστρώματος μέχρι 10cm, 4 παραλιών της Βόρειας Κρήτης, με τη μέθοδο της συστηματικής δειγματοληψίας. Τα pellets διαχωρίστηκαν σε 6 κατηγορίες με βάση το χρώμα (νέα λευκά, παλαιά λευκά, υπόλευκα, πορτοκαλί, καφέ και έγχρωμα), ενώ τα τμήματα πλαστικών σε 4 κλάσεις μεγέθους (0-4mm, 4-15mm, 15-50mm και >50mm) και για κάθε κατηγορία μετρήθηκαν οι αφθονίες και τα βάρη σε g. Μετρήθηκαν, επίσης, οι αφθονίες των πλαστικών που καλύπτονταν από πίσσα. Μετά από στατιστική επεξεργασία των δεδομένων, εξήχθησαν συμπεράσματα σχετικά με τις κατανομές των πλαστικών συνολικά, αλλά και των επιμέρους κατηγοριών, κατά μήκος και κατά πλάτος των παραλιών, αλλά και στην επιφάνεια σε σχέση με το υπόστρωμα, καθιστώντας έτσι δυνατή την κατανόηση της συμπεριφοράς των πλαστικών αλλά και των ίδιων των παραλιών.

description: In this paper we define a relative rigid fundamental group, which associates to a section $p$ of a smooth and proper morphism $f:X\rightarrow S$ in characteristic $p$, a Hopf algebra in the ind-category of overconvergent $F$-isocrystals on $S$. We prove a base change property, which says that the fibres of this object are the Hopf algebras of the rigid fundamental groups of the fibres of $f$. We explain how to use this theory to define period maps as Kim does for varieties over number fields, and show in certain cases that the targets of these maps can be interpreted as varieties.

description: This thesis considers Malta, part of the understudied subject area of small states, and outlines a media system which is the product of a micro economy and unique societal culture. Taking a case-study approach, three news organisations are examined to understand the editorial routines, ownership and management structures, and social and cultural factors that affect the day-to-day business of creating news. To establish the fit between what is asserted by staff and what is actually taking place in the news-generation process, in-depth interviews with key stakeholders of each organisation are conducted alongside qualitative textual analysis of the content they publish. Contrary to previous research, we find advocacy continues to dominate Maltese journalism, indicating that the country has retained similarities to other media systems within its geographic region. However, this advocacy presents in different ways, influencing the nature of each organisation’s respective reporting and reflecting individual workplace cultures, routines and ownership structures, as well as constituting a response to the politically involved society in which they operate. This conflicts with the ideal typification advanced by Hallin and Mancini. The findings highlight the merits of the Maltese tradition – found wanting in the US objectivity canon. In this small state, journalistic advocacy extends media diversity and contributes to the high level of political engagement among its population.

description: This paper extends Alexander duality to the setting of parametrized homology. Let X with be a compact subset of R^n x R (n \geq 2) satisfying certain conditions, let Y be its complement, and let p be the projection onto the second factor. Both X and Y are parametrized spaces with respect to the projection. The parametrized homology is a variant of zigzag persistent homology that measures how the homology of the level sets of the space changes as we vary the parameter. We show that if (X, p|_X) has a well-defined parametrized homology, then the pair (Y, p|_Y) has a well-defined reduced parametrized homology. We also establish a relationship between the parametrized homology of (X, p|_X) and the reduced parametrized homology of (Y, p|_Y).

description: The infinite upper triangular Pascal matrix is $T = [\binom{j}{i}]$ for $0\leq i,j$. It is easy to see that any leading principle square submatrix is triangular with determinant $1$, hence invertible. In this paper, we investigate the invertibility of arbitrary square submatrices $T_{r,c}$ comprised of rows $r=[r_0,\ldots,r_m]$ and columns $c=[c_0,\ldots,c_m]$ of $T$. We show that $T_{r,c}$ is invertible iff $r \leq c$ (i.e., $r_i \leq c_i$ for $i=0, \ldots, m$), or equivalently, iff all diagonal entries are nonzero. To prove this result we establish a connection between the invertibility of these submatrices and polynomial interpolation. In particular, we apply the theory of Birkhoff interpolation and \polya{} systems.
