Practice and its Overflows: Reflections on Order and Mess
Creators: name: Suchman, Lucy
Publisher: name: Tecnoscienza – Italian Journal of Science & Technology Studies
Year: 2011

description: The starting point of this paper is the problem of how STS researchers make the objects of their research, considering that researchers are an integral part of the practices through which their research objects are made. A “center of coordination” in an airport is used as an example to show how a schedule, used as an ordering device within the ongoing work, operates at the same time as a form of normative prescription for what the work should come to. The schedule demonstrates how prescriptive representations presuppose the work of their enactment, in ways that differ from representations used to describe “natural” events, insofar as the former are constitutive of the processes and practices to which the artifacts are accountable. Finally the paper draws on the work of John Law (2004) to show how consistent relations, i.e. orderings, are maintained through routines that, in producing other relations, constitute mess. In this respect, the order created by the researcher in analyzing the situated use of the schedule is not different in kind from the order created by the members’ practices to manage the traffic of planes.

A Text of Texts…almost a Texture
Creators: name: Gherardi, Silvia
Publisher: name: Tecnoscienza – Italian Journal of Science & Technology Studies
Year: 2011

description: This lecture intends to be a journey through ongoing conversations that over time gave a situated meaning to the black box of STS. It tells the story (or rather stories) of how these perspectives have influenced the study targets of various groups of researchers, mainly sociologists and students of organization, technology and science. Using a narrative technique, it places the reference texts of the authors who have helped to build the STS perspective centre stage. The lecture focuses on traditions, authors and intellectual and research trajectories, and then concentrates on the ways in which we are preparing to pass the baton to a younger generation of academics, both in Italy and elsewhere. It also highlights how this new generation is acquiring relevance in the ongoing debate surrounding the social sciences. The texts examined represent the dense texture of the diverse STS perspectives.

description: CeCu$_2$Si$_2$ is an exemplary correlated electron metal that features two domes of unconventional superconductivity in its temperature-pressure phase diagram. The first dome surrounds an antiferromagnetic quantum critical point, whereas the more exotic second dome may span the termination point of a line of $f$-electron valence transitions. This behavior has received intense interest, but what has been missing are ways to access the high pressure behavior under milder conditions. Here we study Si $\rightarrow$ P chemical substitution, which compresses the unit cell volume but simultaneously weakens the hybridization between the $f$- and conduction electron states and encourages complex magnetism. At concentrations that show magnetism, applied pressure suppresses the magnetic ordering temperature and superconductivity is recovered for samples with low disorder. These results reveal that the electronic behavior in this system is controlled by a nontrivial combination of effects from unit cell volume and electronic shell filling. Guided by this topography we discuss prospects for uncovering a valence fluctuation quantum phase transition in the broader family of Ce-based ThCr$_2$Si$_2$-type materials through chemical substitution.

description: We present a method of sensing AC magnetic fields. The method is based on the construction of a robust qubit by the application of continuous driving fields. Specifically, magnetic noise and power fluctuations of the driving fields do not operate within the robust qubit subspace, and hence, robustness to both external and controller noise is achieved. We consider trapped-ion based implementation via the dipole transitions, which is relevant for several types of ions, such as the $^{40}{\rm{Ca}}^{+}$, $^{88}{\rm{Sr}}^{+}$, and the $^{138}{\rm{Ba}}^{+}$ ions. Taking experimental errors into account, we conclude that the coherence time of the robust qubit can be improved by up to $\sim 4$ orders of magnitude compared to the coherence time of the bare states. We show how the robust qubit can be utilized for the task of sensing AC magnetic fields, leading to an improvement of $\sim 2$ orders of magnitude of the sensitivity. In addition, we present a microwave based sensing scheme that is suitable for ions with a hyperfine structure, such as the $^{9}{\rm{Be}}^{+}$,$^{25}{\rm{Mg}}^{+}$,$^{43}{\rm{Ca}}^{+}$,$^{87}{\rm{Sr}}^{+}$,$^{137}{\rm{Ba}}^{+}$,$^{111}{\rm{Cd}}^{+}$,$^{171}{\rm{Yb}}^{+}$, and the $^{199}{\rm{Hg}}^{+}$ ions. This scheme enables the enhanced sensing of high frequency fields at the GHz level.

description: In this work the conducting properties of graphene lattice with a particular concentration of defect (5\% and 10\%) has been studied. The real space block recursion method introduced by Haydock et al. has been used in presence of the random distribution of defects in graphene. This Green function based method is found more powerful than the usual reciprocal based methods which need artificial periodicity. Different resonant states appear because of the presence of topological and local defects are studied within the framework of Green function.
A Pati-Salam SUSY GUT with Yukawa Unification

description: Previous studies of a three family Yukawa unified supersymmetric grand unified theory (SUSY GUT) with SO(10) or Pati-Salam (PS) gauge symmetry proposed by Raby and students show that this model is able to fit low energy and inflation observables. However, the fit to low energy observables is not great especially for $\sin2β$, and up and down quark masses. In this paper, we show that by choosing PS as the gauge group and modifying the Yukawa sector, the low energy fit improves significantly while other qualities of the model are maintained. In particular, the lightest SUSY particle is the neutralino with mass of order 300 - 500 GeV, the lightest stop and sbottom have mass of order 3 - 5 TeV and the CP odd Higgs mass is of order 5 - 6 TeV, so we are in the decoupling limit for the light Higgs. In addition, we reinterpret gluino simplified model analyses by the ATLAS and CMS collaborations and find that the most stringent gluino mass bound for our model is $M_{\tilde{g}}\sim1.9\,\text{TeV}$. The current best fit point, consistent with this bound, with gluino mass $M_{\tilde{g}}=1.9\,\text{TeV}$ has $χ^2/\text{dof}\approx1.12$, compared to the best fit point of the previous model with $χ^2/\text{dof}=1.90$. We find that predictions for the electric dipole moment of the electron, the branching ratio $BR(μ\rightarrow e γ)$ and the CP violating angle in the lepton sector, $\sinδ$, are affected significantly as compared to previous results. In summary, we are unable to rule out this model or place an upper bound on gluino mass accessible by this run of the LHC because the $χ^2/\text{dof}$ of this model is well below $2σ$ even for a gluino mass as high as 2.7 TeV. On the bright side, this means that this model is still viable and we might find low energy SUSY particles in the near future.

description: Η εργασία αυτή πραγματεύεται το πρόβλημα του σχεδιασμού τροχιάς για ένα αυτόνομο όχημα. Ο σχεδιασμός τροχιάς είναι ένα απαραίτητο τμήμα στην προετοιμασία μιας αποστολής, καθώς ένα αυτόνομο όχημα θα πρέπει να γνωρίζει εκ των προτέρων την διαδρομή που πρέπει να ακολουθήσει. Το πρόβλημα είναι ανοικτό καθώς δεν υπάρχει λύση που να καλύπτει κάθε πιθανή περίπτωση, ενώ υπάρχει πληθώρα τρόπων αντιμετώπισης του προβλήματος στην επιστημονική βιβλιογραφία οι οποίοι εστιάζουν σε διαφορετικές κατηγορίες οχημάτων, περιβάλλοντα, εργαλεία ή και συγκεκριμένες τεχνικές.
Στην εργασία αυτή θα παρουσιασθεί μια νέα πρόταση για την επίλυση του προβλήματος, η οποία αντιμετωπίζει τόσο την δημιουργία ασφαλών (χωρίς συγκρούσεις) τροχιών, όσο και την βελτιστοποίηση τους ως προς τα εκάστοτε επιθυμητά κριτήρια. Συγκεκριμένα, για την δημιουργία των τροχιών έχει εφαρμοστεί μια προσέγγιση βασισμένη σε αρχές κινηματικής ενώ για την βελτιστοποίηση χρησιμοποιείται μια μεθοδολογία με γενετικούς αλγόριθμους.  Βασικός στόχος της πρότασης είναι η δυνατότητα εφαρμογής σε πραγματικά χαρτογραφικά δεδομένα και σε διαφορετικούς τύπους οχημάτων, ενώ έμφαση έχει δοθεί και στην διατήρηση μιας εύκολα παραμετροποιήσιμης και επεκτάσιμης συνολικής δομής ώστε να μπορούν να καλυφθούν ανάγκες που δεν έχουν προβλεφθεί και μελετηθεί εκ των προτέρων.
Στα εισαγωγικά κεφάλαια της εργασίας παρατίθεται μια σύντομη περιγραφή του προβλήματος, μια ανασκόπηση μεθόδων επίλυσης με ιδιαίτερη μνεία σε κάποιες συναφείς τεχνικές καθώς και κάποια προαπαιτούμενα στοιχεία για την κατανόηση της προτεινόμενης μεθοδολογίας. Στην συνέχεια θα παρουσιασθεί αναλυτικά τόσο ο μηχανισμός δημιουργίας τροχιών όσο και ο μηχανισμός βελτιστοποίησης τους, μαζί με αποτελέσματα από ενδεικτικές δοκιμές με πραγματικά χαρτογραφικά δεδομένα. Στα τελευταία κεφάλαια θα συζητηθεί η επέκταση της μεθοδολογίας αυτής ώστε να καλύπτει περιπτώσεις ταυτόχρονου σχεδιασμού τροχιάς για πολλαπλά οχήματα, ενώ αντίστοιχα θα παρουσιαστούν και θα σχολιαστούν τα αποτελέσματα των σχετικών δοκιμών. Τέλος, στον επίλογο θα γίνει ένας γενικός απολογισμός της συνολικής πρότασης και υλοποίησης, και θα παρατεθούν σημεία που χρήζουν επιπλέον διερεύνησης και αποτελούν ενδεχόμενες μελλοντικές εργασίες.

description: Nanocomposite hydrogels offer remarkable potential for applications in bone tissue engineering. They are synthesized through the chemical or physical crosslinking of polymers and nanomaterials, allowing for the enhancement of their behaviour by modifying the properties and compositions of the nanomaterials involved. However, their mechanical properties require further enhancement to meet the demands of bone tissue engineering. Here, we present an approach to improve the mechanical properties of nanocomposite hydrogels by incorporating polymer grafted silica nanoparticles into a double network inspired hydrogel (gSNP Gels). The gSNP Gels were synthesised via a graft polymerization process using a redox initiator. gSNP Gels were formed by grafting 2-acrylamido-2-methylpropanesulfonic acid (AMPS) as the first network gel followed by a sequential second network acrylamide (AAm) onto amine functionalized silica nanoparticles (ASNPs). We utilized glucose oxidase (GOx) to create an oxygen-free atmosphere during polymerization, resulting in higher polymer conversion compared to argon degassing. The gSNP Gels showed excellent compressive strengths of 13.9 ± 5.5 MPa, a strain of 69.6 ± 6.4%, and a water content of 63.4% ± 1.8. The synthesis technique demonstrates a promising approach to enhance the mechanical properties of hydrogels, which can have significant implications for bone tissue engineering and other soft tissue applications.
Information Dimension of Stochastic Processes on Networks: Relating Entropy Production to Spectral Properties

description: We consider discrete stochastic processes, modeled by classical master equations, on networks. The temporal growth of the lack of information about the system is captured by its non-equilibrium entropy, defined via the transition probabilities between different nodes of the network. We derive a relation between the entropy and the spectrum of the master equation's transfer matrix. Our findings indicate that the temporal growth of the entropy is proportional to the logarithm of time if the spectral density shows scaling. In analogy to chaos theory, the proportionality factor is called (stochastic) information dimension and gives a global characterization of the dynamics on the network. These general results are corroborated by examples of regular and of fractal networks.

description: Though formally reunified in 1990, the Federal Republic of Germany in many ways remains a deeply divided country. East Germans face higher unemployment rates, lower wages, worse access to healthcare, and decaying infrastructure among other challenging circumstances. Significant portions of the East German population feel alienated from the political system, with the most established parties – largely dominated by West German politicians – seemingly unable to connect with the East German electorate. Meanwhile, the communist successor party Die Linke and the right-wing populist Alternative für Deutschland (AfD) frequently gain pluralities – in some cases even majorities – of the East German vote in state and federal elections. In their campaigns, these parties often evoke sentiments of Ostalgie, nostalgia for the socialist past, and present themselves as East German Volksparteien, people’s parties. In this paper, I analyze the rhetoric of members of the German Bundestag towards the communist German Democratic Republic (GDR) and East Germany as a region. A sentiment analysis of all speeches given in the Bundestag between 1990 and 2021 reveals that representatives of PDS/Die Linke and the AfD are significantly more positive in their rhetoric towards East Germany and the GDR than their peers from the established, more centrist parties. Further, whether or not a representative was born in East Germany has little effect on their expressed sentiment towards the region and its communist past. Through natural language processing, this study contributes empirically to scholarly conversations around alienation, representation, and populism in postcommunist East Germany.

description: We introduce a multi-mode squeezing coefficient to characterize entanglement in $N$-partite continuous-variable systems. The coefficient relates to the squeezing of collective observables in the $2N$-dimensional phase space and can be readily extracted from the covariance matrix. Simple extensions further permit to reveal entanglement within specific partitions of a multipartite system. Applications with nonlinear observables allow for the detection of non-Gaussian entanglement.

description: Spiking neural network (SNN), as the next generation of artificial neural network (ANN), offer a closer mimicry of natural neural networks and hold promise for significant improvements in computational efficiency. However, the current SNN is trained to infer over a fixed duration, overlooking the potential of dynamic inference in SNN. In this paper, we strengthen the marriage between SNN and event-driven processing with a proposal to consider a cutoff in SNN, which can terminate SNN anytime during inference to achieve efficient inference. Two novel optimisation techniques are presented to achieve inference efficient SNN: a Top-K cutoff and a regularisation.The proposed regularisation influences the training process, optimising SNN for the cutoff, while the Top-K cutoff technique optimises the inference phase. We conduct an extensive set of experiments on multiple benchmark frame-based datasets, such asCIFAR10/100, Tiny-ImageNet, and event-based datasets, including CIFAR10-DVS, N-Caltech101 and DVS128 Gesture. The experimental results demonstrate the effectiveness of our techniques in both ANN-to-SNN conversion and direct training, enabling SNNs to require 1.76 to 2.76x fewer timesteps for CIFAR-10, while achieving 1.64 to 1.95x fewer timesteps across all event-based datasets, with near-zero accuracy loss. These findings affirms the compatibility and potential benefits of our techniques in enhancing accuracy and reducing inference latency when integrated with existing methods.

description: Cellular automata (CAs) are notable computational models exhibiting rich dynamics emerging from the local interaction of cells arranged in a regular lattice. Graph CAs (GCAs) generalise standard CAs by allowing for arbitrary graphs rather than regular lattices, similar to how Graph Neural Networks (GNNs) generalise Convolutional NNs. Recently, Graph Neural CAs (GNCAs) have been proposed as models built on top of standard GNNs that can be trained to approximate the transition rule of any arbitrary GCA. We note that existing GNCAs can violate the locality principle of CAs by leveraging global information and, furthermore, are anisotropic in the sense that their transition rules are not equivariant to isometries of the nodes' spatial locations. However, it is desirable for instances related by such transformations to be treated identically by the model. By replacing standard graph convolutions with E(n)-equivariant ones, we avoid anisotropy by design and propose a class of isotropic automata that we call E(n)-GNCAs. These models are lightweight, but can nevertheless handle large graphs, capture complex dynamics and exhibit emergent self-organising behaviours. We showcase the broad and successful applicability of E(n)-GNCAs on three different tasks: (i) isotropic pattern formation, (ii) graph auto-encoding, and (iii) simulation of E(n)-equivariant dynamical systems.

description: We present the first results from applying the spectral inversion technique in the cloudy L dwarf regime. Our new framework provides a flexible approach to modelling cloud opacity which can be built incrementally as the data requires, and improves upon previous retrieval experiments in the brown dwarf regime by allowing for scattering in two stream radiative transfer. Our first application of the tool to two mid-L dwarfs is able to reproduce their near-infrared spectra far more closely than grid models. Our retrieved thermal, chemical, and cloud profiles allow us to estimate $T_{\rm eff} = 1796^{+23}_{-25}$ K and $\log g = 5.21^{+0.05}_{-0.08}$ for 2MASS J05002100+0330501 and for 2MASSW J2224438-015852 we find $T_{\rm eff} = 1723^{+18}_{-19}$ K and $\log g = 5.31^{+0.04}_{-0.08}$, in close agreement with previous empirical estimates. Our best model for both objects includes an optically thick cloud deck which passes $τ_{cloud} \geq 1$ (looking down) at a pressure of around 5 bar. The temperature at this pressure is too high for silicate species to condense, and we argue that corundum and/or iron clouds are responsible for this cloud opacity. Our retrieved profiles are cooler at depth, and warmer at altitude than the forward grid models that we compare, and we argue that some form of heating mechanism may be at work in the upper atmospheres of these L dwarfs. We also identify anomalously high CO abundance in both targets, which does not correlate with the warmth of our upper atmospheres or our choice of cloud model, and find similarly anomalous alkali abundance for one of our targets. These anomalies may reflect unrecognised shortcomings in our retrieval model, or inaccuracies in our gas phase opacities.

description: The Role of Civil Society Involvement in Crisis Management – is a task focused on exploring the increasingly recognized role of civil society in crisis management. In T2.3, civil society includes volunteers, non-governmental organizations (NGOs), and local communities. In order to identify the main challenges and best practices relating to the role of civil society in crisis management, a set of qualitative research methods were employed including semi-structured interviews, focus groups, and case studies with SnR organizations and volunteers, as well as local communities. This extensive research involving 45 semi-structured interviews, 3 focus groups, and 32 case studies allowed for the emergence of patterns and themes pinpointing the advantages, challenges, best practices, and limitations of civil society involvement in crisis management. The data collection and analysis in T2.3 culminated in D2.3 – Report on the Role of Civil Society Involvement in Crisis Management. D2.3 includes a detailed description of the research findings that are categorized according to the emergent themes. It also includes a SWOT analysis based on the themes. Moreover, the report and SWOT analysis are contextualized with the broader crisis management literature for further relevance. D2.3 concludes with a set of recommendations for future research, as well as the crisis management field more broadly.

description: Discovery of unexpected properties of the Higgs boson offers an intriguing opportunity of shedding light on some of the most profound puzzles in particle physics. The Beyond Standard Model (BSM) decays of the Higgs boson could reveal new physics in a direct manner. Future electron-positron lepton colliders operating as Higgs factories, including CEPC, FCC-ee and ILC, with the advantages of a clean collider environment and large statistics, could greatly enhance the sensitivity in searching for these BSM decays. In this work, we perform a general study of Higgs exotic decays at future $e^+e^-$ lepton colliders, focusing on the Higgs decays with hadronic final states and/or missing energy, which are very challenging for the High-Luminosity program of the Large Hadron Collider (HL-LHC). We show that with simple selection cuts, $O(10^{-3}\sim10^{-5})$ limits on the Higgs exotic decay branching fractions can be achieved using the leptonic decaying spectator $Z$ boson in the associated production mode $e^+e^-\rightarrow Z H$. We further discuss the interplay between the detector performance and Higgs exotic decay, and other possibilities of exotic decays. Our work is a first step in a comprehensive study of Higgs exotic decays at future lepton colliders, which is a key ingredient of Higgs physics that deserves further investigation.

description: This paper is concerned with the intrinsic geometric structure of interior transmission eigenfunctions arising in wave scattering theory. We numerically show that the aforementioned geometric structure can be much delicate and intriguing. The major findings can be roughly summarized as follows. If there is a cusp on the support of the underlying potential function, then the interior transmission eigenfunction vanishes near the cusp if its interior angle is less than $π$, whereas the interior transmission eigenfunction localizes near the cusp if its interior angle is bigger than $π$. Furthermore, we show that the vanishing and blowup orders are inversely proportional to the interior angle of the cusp: the sharper the angle, the higher the convergence order. Our results are first of its type in the spectral theory for transmission eigenvalue problems, and the existing studies in the literature concentrate more on the intrinsic properties of the transmission eigenvalues instead of the transmission eigenfunctions. Due to the limitedness of the computing resources, our study is by no means exclusive and complete. We consider our study only in a certain geometric setup including corner, curved corner and edge singularities. Nevertheless, we believe that similar results hold for more general cusp singularities and rigorous theoretical justifications are much desirable. Our study enriches the spectral theory for transmission eigenvalue problems. We also discuss its implication to inverse scattering theory.

description: We study an extended Standard Model with a gauged U(1)$^{\prime}$ flavor symmetry, motivated not only by the fermion mass hierarchy but also by the excesses in $B \to K^{(*)} l l$ reported by the LHCb collaborations. The U(1)$^{\prime}$ charges are assigned to quarks and leptons in a flavor-dependent manner, and flavored Higgs doublets are also introduced in order to detail the Yukawa couplings at the renormalizable level. Then, the fermion mass hierarchy is realized by the vacuum alignment of the Higgs doublets. In this model, flavor-changing currents involving the gauge boson of U(1)$^{\prime}$ and the scalars generated by the Higgs doublets are predicted and the observables in the $B \to K^{(*)} l l$ process possibly deviate from the Standard Model predictions. We study the possibility that these new flavor-changing interactions can explain the excesses in the $B \to K^{(*)} l l$ process, and we derive some predictions for the other flavor-violating processes based on the analysis. We specifically investigate the $ΔF=2$ processes and the other $B$ decays: e.g., $B \to X_s γ$ and $B \to D^{(*)} τν$, where the deviations are reported by the Belle and $BABAR$ collaborations.

description: Pseudocapacitors are energy-storage devices characterized by fast and reversible redox reactions that enable them to store large amounts of electrical energy at high rates. We simulate the response of pseudocapacitive electrodes under realistic conditions to identify the microscopic factors that determine their performance, focusing on ruthenia (RuO2) as a prototypical electrode material. Electronic-structure methods are used together with a self-consistent continuum solvation (SCCS) model to build a complete dataset of free energies as the surface of the charged electrode is gradually covered with protons under applied voltage. The resulting dataset is exploited to compute hydrogen-adsorption isotherms and charge-voltage responses by means of grand-canonical sampling, finding close agreement with experimental voltammetry. These simulations reveal that small changes on the order of 5 μF/cm2 in the intrinsic double-layer capacitance of the electrode-electrolyte interface can induce variations of up to 40 μF/cm2 in the overall pseudocapacitance.

description: A method is derived for the quantitative analysis of signals that are composed of superpositions of isolated, time-localized "events". Here these events are taken to be well represented as rescaled and phase-rotated versions of generalized Morse wavelets, a broad family of continuous analytic functions. Analyzing a signal composed of replicates of such a function using another Morse wavelet allows one to directly estimate the properties of events from the values of the wavelet transform at its own maxima. The distribution of events in general power-law noise is determined in order to establish significance based on an expected false detection rate. Finally, an expression for an event's "region of influence" within the wavelet transform permits the formation of a criterion for rejecting spurious maxima due to numerical artifacts or other unsuitable events. Signals can then be reconstructed based on a small number of isolated points on the time/scale plane. This method, termed element analysis, is applied to the identification of long-lived eddy structures in ocean currents as observed by along-track measurements of sea surface elevation from satellite altimetry

description: We establish existence and uniqueness of the solution to the Dyson equation for the density-density response function in time-dependent density functional theory (TDDFT) in the random phase approximation (RPA). We show that the poles of the RPA density-density response function are forward-shifted with respect to those of the non-interacting response function, thereby explaining mathematically the well known empirical fact that the non-interacting poles (given by the spectral gaps of the time-independent Kohn-Sham equations) underestimate the true transition frequencies. Moreover we show that the RPA poles are solutions to an eigenvalue problem, justifying the approach commonly used in the physics community to compute these poles.

description: The Nelson model, describing a quantum mechanical particle linearly coupled to a bosonic field, exhibits the infrared problem in the sense that no ground state exists at arbitrary total momentum. However, passing to a non-Fock representation, one can prove the existence of so-called dressed one-particle states. In this article, we give a simple non-perturbative proof for the existence of such one-particle states at arbitrary coupling strength and for almost all total momenta in a physically motivated momentum region. Our results hold both for the non- and the semi-relativistic Nelson model.

National Association of Women Artists (1889-1978) 89th Annual Exhibition, May 11th thru May 28th, 1978
Creators: name: No Name Supplied
Publisher: name: No Publisher Supplied
Year: 1978

description: The National Association of Women Artists (NAWA) was established in 1889 and is the oldest professional women's fine arts organization in the United States. NAWA's mission is to promote awareness of, and interest in, visual art created by women in the United States. As part of this effort NAWA holds an annual exhibition of works by members of the association and publishes an exhibition catalog to accompany or commemorate the annual exhibitions. These catalogs not only function as an exhibition catalog, but also as a document that summarizes the structure, membership, and activities of the association.Information that can be found in these catalogs includes lists of officers, members of the executive board and committees, prize winners, lists of exhibitor and members, and images of some of the artwork exhibited. Catalogs from the 2000s also include information on NAWA events and activities beyond the annual exhibition.Please note that the numbering of the annual catalogs was adjusted in 1960 and again in 1971. For example, NAWA designated the annual exhibition in 1960 as the 70th Anniversary Exhibition after 1959 was the 67th Annual Exhibition. These adjustments appear to have been made to reflect the date of the founding of the association, so that, by 1989, the annual exhibition commemorated the 100-year anniversary of the founding of NAWA in 1889.

description: We report on temperature-dependent magnetospectroscopy of two HgTe/CdHgTe quantum wells below and above the critical well thickness $d_c$. Our results, obtained in magnetic fields up to 16 T and temperature range from 2 K to 150 K, clearly indicate a change of the band-gap energy with temperature. The quantum well wider than $d_c$ evidences a temperature-driven transition from topological insulator to semiconductor phases. At the critical temperature of 90 K, the merging of inter- and intra-band transitions in weak magnetic fields clearly specifies the formation of gapless state, revealing the appearance of single-valley massless Dirac fermions with velocity of $5.6\times10^5$ m$\times$s$^{-1}$. For both quantum wells, the energies extracted from experimental data are in good agreement with calculations on the basis of the 8-band Kane Hamiltonian with temperature-dependent parameters.

description: We provide a procedure to determine if a given nonlocal operator in a large N holographic CFT is dual to a local bulk operator on the geometry associated with a particular code subspace of the CFT. This procedure does not presuppose knowledge of the bulk geometry. We are able to pick out local operators in a large region of the bulk, called the "localizable region,"' that can extend beyond event horizons in certain cases. The method relies heavily on the quantum-error correcting structure of AdS/CFT and, in particular, on entanglement wedge reconstruction. As a byproduct of this machinery, we are able to reconstruct the metric in the localizable region up to a conformal factor. This suggests a connection between our program and the recent light-cone cut approach to bulk reconstruction.
