One Hundred Years: A Centennial Celebration of the National Association of Women Artists, October 16 - December 31, 1988
Creators: name: No Name Supplied
Publisher: name: No Publisher Supplied
Year: 1988

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: Ο σκοπός της παρούσας εργασίας είναι η εξέταση του εθνικιστικού ή αντιεθνικιστικού προφίλ του Σύριζα κατά την διακυβέρνησή του την περίοδο 2015-2019. Η θεματική αυτή επιλέγεται, καθώς παρουσιάζει αρκετά μεγάλο ενδιαφέρον η ανάλυση των ιδεολογικών πτυχών ενός κόμματος το οποίο εντάσσεται στην αριστερά, ως προς τις θέσεις του περί εθνικής κυριαρχίας (εθνικισμού), έννοια που παρουσιάζεται ως βασική στη συγκεκριμένη διπλωματική εργασία. Έμφαση θα δοθεί σε ένα μείζον θέμα που μπορεί αρχικά να φαίνεται ως παράδοξο, δηλαδή η σχέση του εθνικισμού που είναι μια ιδεολογία που θα περίμενε κανείς να συναντάται εν πολλοίς στην (άκρα) δεξιά και το κέντρο, με την αριστερά και ένα κόμμα που εκπροσωπεί τη ριζοσπαστική της πτέρυγα. Η δομή της εργασίας θα βασιστεί πάνω σε εμπειρικό υλικό (συνεντεύξεις, άρθρα, ομιλίες), που συναντάται στην εξεταζόμενη περίοδο της διακυβέρνησης του Σύριζα και έχει σχέση με τα μεγάλα και κρίσιμα εθνικά ζητήματα της Ελλάδας, και σε βιβλιογραφία που θα περιλαμβάνει θεωρίες περί εθνικισμού. Τελικός σκοπός της εκπόνησης αυτής της εργασίας είναι το να αποφανθεί αν και κατά πόσο η ρητορική του Σύριζα κατά την «πρώτη φορά Αριστερά» χαρακτηρίζεται εθνικιστική, αντι-εθνικιστική ή ενδεχομένως κάτι άλλο
description: The aim of the present thesis is the examination of the nationalistic or anti-nationalistic profile of Syriza during its’ administration in 2015-2019. This subject area is being chosen, because there is so much interest in analyzing the ideological strands of a political party that is considered left-wing in regards to its’ national sovereignty (nationalism) views, a concept that is presented as very crucial in this specific thesis. A major issue, which may seem initially as paradox, will be emphasized and this is the correlation between nationalism, an ideology that is expected to be found mostly in (far)-Right and the Centre, the Left and a party that represents its’ radical flank. The structure of the thesis will be based on empirical material (interviews, articles, rallies), that can be found in the examined period of the Syriza administration and is related with the great and critical national affairs of Greece, and on bibliography including theories of nationalism. The final aim of carrying out this thesis is to adjudge if and whether Syriza’s discourse during its’ “Left for the first time” era can be defined as nationalistic, anti-nationalistic or, potentially, something else

description: Humanities have convincingly argued that they need transnational research opportunities and through the digital transformation of their disciplines also have the means to proceed with it on an up to now unknown scale. The digital transformation of research and its resources means that many of the artifacts, documents, materials, etc. that interest humanities research can now be combined in new and innovative ways. Due to the digital transformations, (big) data and information have become central to the study of culture and society. Humanities research infrastructures manage, organise and distribute this kind of information and many more data objects as they becomes relevant for social and cultural research.

description: We propose a new approach for generating synthetic earthquake catalogues based on the physics of soft glasses. The continuum approach produces yield-stress materials based on Lattice-Boltzmann simulations. We show that, if the material is stimulated below yield stress, plastic events occur, which have strong similarities with seismic events. Based on a suitable definition of displacement in the continuum, we show that the plastic events obey a Gutenberg-Richter law with exponents similar to those for real earthquakes. We further find that average acceleration, energy release, stress drop and recurrence times scale with the same exponent. The approach is fully self-consistent and all quantities can be calculated at all scales without the need of ad hoc friction or statistical laws. We therefore suggest that our approach may lead to new insight into understanding of the physics connecting the micro and macro scale of earthquakes.

description: As a quantum resource, quantum coherence plays an important role in modern physics. Many coherence measures and their relations with entanglement have been proposed, and the dynamics of entanglement has been experimentally studied. However, the knowledge of general results for coherence dynamics in open systems is limited. Here we propose a coherence factorization law, which describes the evolution of coherence passing through any noisy channels characterized by genuinely incoherent operations. We use photons to implement the quantum operations and experimentally verify the law for qubits and qutrits. Our work is a step toward the understanding of the evolution of coherence when the system interacts with the environment, and will boost the study of more general laws of coherence.

description: Electromagnetic (EM) wave detection over a large spectrum has recently attracted significant amount of attention. Traditional electronic EM wave sensors use large metallic probes which distort the field to be measured and also have strict limitations on the detectable RF bandwidth. To address these problems, integrated photonic EM wave sensors have been developed to provide high sensitivity and broad bandwidth. Previously we demonstrated a compact, broadband, and sensitive integrated photonic EM wave sensor, consisting of an organic electro-optic (EO) polymer refilled silicon slot photonic crystal waveguide (PCW) modulator integrated with a gold bowtie antenna, to detect the X band of the electromagnetic spectrum. However, due to the relative large RC constant of the silicon PCW, such EM wave sensors can only work up to tens of GHz. In this work, we present a detailed design and discussion of a new generation of EM wave sensors based on EO polymer refilled plasmonic slot waveguides in conjunction with bowtie antennas to cover a wider electromagnetic spectrum from 1 GHz up to 10THz, including the range of microwave, millimeter wave and even terahertz waves. This antenna-coupled plasmonic-organic hybrid (POH) structure is designed to provide an ultra-small RC constant, a large overlap between plasmonic mode and RF field, and strong electric field enhancement, as well as negligible field perturbation. A taper is designed to bridge silicon strip waveguide to plasmonic slot waveguide. Simulation results show that our device can have an EM wave sensing ability up to 10 THz. To the best of our knowledge, this is the first POH device for photonic terahertz wave detection.

description: We numerically investigate the electronic structures around a vortex core in a bilayer superconducting system, with s-wave pairing, Rashba spin-orbit coupling and Zeeman magnetic field, with use of the quasiclassical Green's function method. The Bardeen-Cooper-Schrieffer (BCS) phase and the so-called pair-density wave (PDW) phase appear in the temperature-magnetic-field phase diagram in a bulk uniform system [Phys. Rev. B 86, 134514 (2012)]. In the low magnetic field perpendicular to the layers, the zero-energy vortex bound states in the BCS phase are split by the Zeeman magnetic field. On the other hand, the PDW state appears in the high magnetic field, and sign of the order parameter is opposite between the layers. We find that the vortex core suddenly shrinks and the zero-energy bound states appear by increasing the magnetic field through the BCS-PDW transition. We discuss the origin of the change in vortex core structure between the BCS and PDW states by clarifying the relation between the vortex bound states and the bulk energy spectra. In the high magnetic field region, the PDW state and vortex bound states are protected by the spin-orbit coupling. These characteristic behaviors in the PDW state can be observed by scanning tunneling microscopy/spectroscopy.

description: A neutral boundary layer was generated in the laboratory to analyze the mean velocity field and the turbulence field within and above an array of two-dimensional obstacles simulating an urban canopy. Different geometrical configurations were considered in order to investigate the main characteristics of the flow as a function of the aspect ratio (AR) of the canopy. To this end, a summary of the two-dimensional fields of the fundamental turbulence parameters is given for AR ranging from 1 to 2. The results show that the flow field depends strongly on AR only within the canyon, while the outer flow seems to be less sensitive to this parameter. This is not true for the vertical momentum flux, which is one of the parameters most affected by AR, both within and outside the canyon. The experiments also indicate that, when (i.e. the skimming flow regime), the roughness sub-layer extends up to a height equal to 1.25 times the height of the obstacles (H), surmounted by an inertial sub-layer that extends up to 2.7 H. In contrast, for (i.e. the wake-interference regime) the inertial sub-layer is not present. This has significant implications when using similarity laws for deriving wind and turbulence profiles in canopy flows. Furthermore, two estimations of the viscous dissipation rate of turbulent kinetic energy of the flow are given. The first one is based on the fluctuating strain rate tensor, while the second is related to the mean strain rate tensor. It is shown that the two expressions give similar results, but the former is more complicated, suggesting that the latter might be used in numerical models with a certain degree of reliability. Finally, the data presented can also be used as a dataset for the validation of numerical models.

description: We investigate the logarithmic negativity in strongly-disordered spin chains in the random-singlet phase. We focus on the spin-1/2 random Heisenberg chain and the random XX chain. We find that for two arbitrary intervals the disorder-averaged negativity and the mutual information are proportional to the number of singlets shared between the two intervals. Using the strong-disorder renormalization group (SDRG), we prove that the negativity of two adjacent intervals grows logarithmically with the intervals length. In particular, the scaling behavior is the same as in conformal field theory, but with a different prefactor. For two disjoint intervals the negativity is given by a universal simple function of the cross ratio, reflecting scale invariance. As a function of the distance of the two intervals, the negativity decays algebraically in contrast with the exponential behavior in clean models. We confirm our predictions using a numerical implementation of the SDRG method. Finally, we also implement DMRG simulations for the negativity in open spin chains. The chains accessible in the presence of strong disorder are not sufficiently long to provide a reliable confirmation of the SDRG results.

description: We consider a periodic-parabolic eigenvalue problem with a non-negative potential $λm$ vanishing on a non-cylindrical domain $D_m$ satisfying conditions similar to those for the parabolic maximum principle. We show that the limit as $λ\to\infty$ leads a periodic-parabolic problem on $D_m$ having a unique periodic-parabolic principal eigenvalue and eigenfunction. We substantially improve a result from [Du & Peng, Trans. Amer. Math. Soc. 364 (2012), p. 6039-6070]. At the same time we offer a different approach based on a periodic-parabolic initial boundary value problem. The results are motivated by an analysis of the asymptotic behavior of positive solutions to semi-linear logistic periodic-parabolic problems with temporal and spacial degeneracies.

description: We show how to use properties of the quantum conditional mutual information to obtain continuity bounds for information characteristics of quantum channels depending on their input dimension. First we prove tight estimates for variation of the output Holevo quantity with respect to simultaneous variations of a channel and of an input ensemble. Then we obtain tight continuity bounds for output conditional mutual information for a single channel and for $n$ copies of a channel. As a result tight and close-to-tight continuity bounds for basic capacities of quantum channels depending on the input dimension are obtained. They complement the Leung-Smith continuity bounds depending on the output dimension.

description: The GRadient Ascent Pulse Engineering (GRAPE) method is widely used for optimization in quantum control. GRAPE is gradient search method based on exact expressions for gradient of the control objective. It has been applied to coherently controlled closed and open quantum systems. In this work, we adopt GRAPE method for optimizing objective functionals for open quantum systems driven by both coherent and incoherent controls. In our case, the tailored or engineered environment acts on the system as control via it time-dependent decoherence rates $γ_k(t)$ or, equivalently, via it spectral density of the environment $n_ω(t)$. To develop GRAPE approach for this problem, we compute gradient of various objectives for general N-level open quantum systems both for piecewise class of control. The case of a single qubit is considered in details and solved analytically. For this case, an explicit analytical expression for evolution and objective gradient is obtained via diagonalization of a $3\times 3$ matrix determining the system's dynamics in the Bloch ball. The diagonalization is obtained by solving a cubic equation via Cardano's method. The efficiency of the algorithm is demonstrated through numerical simulations for the state-to-state transition problem and its complexity is estimated.

Our results demonstrate that, after Klein tunneling through the barrier, the electron acquires an extra energy which depends on the rate of change the barrier height in time. If such a rate is negative, the electron loses energy and ends up as a valence band state after leaving the barrier, which effectively behaves as a positively charged quasi-particle

description: Die vorliegende Handreichung entsteht im Arbeitspaket „Neue Ansätze der Open-Access-Finanzierung“ im Rahmen des BMBF-geförderten Projekts open-access.network 2.

Schwerpunkt des Arbeitspaketes ist es, Workshops und Informationsveranstaltungen zu organisieren, die sich mit der Umsetzung eines (integrierten) Informationsbudgets sowie mit neuen Ansätzen der Finanzierung von Diamond Open Access befassen.

Die Workshopreihe entstand vor dem Hintergrund, dass Hochschulen und Forschungseinrichtungen angehalten sind, integrierte Informationsbudgets zu erarbeiten. Diese Vorgabe resultierte aus den Empfehlungen des Wissenschaftsrates (2022) sowie dem DFG-Förderprogramm „Open-Access-Publikationskosten“. Wie kann und soll ein einrichtungsbezogenes umfassendes Kosten- und Ressourcenmonitoring praktisch umgesetzt werden? Zu dieser Frage besteht bei den Verantwortlichen in den Einrichtungen ein hoher Fortbildungs- und Austauschbedarf. Dies zeigte sich in den hohen Zahlen der Teilnehmer*innen und der durchgehend sehr guten Resonanz auf unsere Workshopreihe „Finanzielle Gestaltung der Open-Access-Transformation an Hochschulen und Wissenschaftseinrichtungen“.

Die hier dokumentierten Veranstaltungen fanden seit Herbst 2023 statt. Mit dieser Handreichung wird der dort gesammelte Wissensschatz gebündelt dokumentiert und allen Interessierten zur Verfügung gestellt. 

Diese Publikation wird weiter wachsen: Als „living document“ wird sie kontinuierlich erweitert werden. Dies geschieht zum einen dynamisch auf unserer Internetseite. Außerdem werden wir Zwischenversionen dieser Handreichung als zitierfähiges Dokument auf Zenodo veröffentlichen.

The study shows that in perpendicular magnetic field resistance oscillates due to electric field induced Landau-Zener transitions between quantum levels that corresponds to geometric resonances between cyclotron orbits and periodic modulation of electron density of states. Magnetic field tilt inverts these oscillations. Surprisingly the strongest inverted oscillations are observed at a tilt corresponding to nearly absent modulation of the electron density of states in regime of magnetic breakdown of semiclassical electron orbits. This phenomenon establishes an example of quantum resistance oscillations due to Landau quantization, which occur in electron systems with a constant density of states.

description: Missing data are a common problem in experimental and observational physics. They can be caused by various sources, either an instrument's saturation, or a contamination from an external event, or a data loss. In particular, they can have a disastrous effect when one is seeking to characterize a colored-noise-dominated signal in Fourier space, since they create a spectral leakage that can artificially increase the noise. It is therefore important to either take them into account or to correct for them prior to e.g. a Least-Square fit of the signal to be characterized. In this paper, we present an application of the {\it inpainting} algorithm to mock MICROSCOPE data; {\it inpainting} is based on a sparsity assumption, and has already been used in various astrophysical contexts; MICROSCOPE is a French Space Agency mission, whose launch is expected in 2016, that aims to test the Weak Equivalence Principle down to the $10^{-15}$ level. We then explore the {\it inpainting} dependence on the number of gaps and the total fraction of missing values. We show that, in a worst-case scenario, after reconstructing missing values with {\it inpainting}, a Least-Square fit may allow us to significantly measure a $1.1\times10^{-15}$ Equivalence Principle violation signal, which is sufficiently close to the MICROSCOPE requirements to implement {\it inpainting} in the official MICROSCOPE data processing and analysis pipeline. Together with the previously published KARMA method, {\it inpainting} will then allow us to independently characterize and cross-check an Equivalence Principle violation signal detection down to the $10^{-15}$ level.

description: Sickle cell anaemia is an inherited disease in which red blood cells become rigid and change from the normal disc shape characteristic of these cells into a sickle-like shape. These abnormally shaped cells stack together and can obstruct small blood vessels, leading to severe pain and tissue damage. They are also fragile and can often burst apart, giving rise to anaemia.Patients with sickle cell anaemia produce 10 to 30 times more of a natural by-product of oxygen metabolism called reactive oxygen species (ROS) than healthy patients. Oxidative stress is an imbalance that results when more ROS are produced than the body’s antioxidant defences can handle. It is thought to be behind certain dysfunctions in people with sickle cell anaemia.A team of researchers in Basra in southern Iraq studied 42 patients with sickle cell anaemia and found evidence of alterations in the levels of oxidative stress markers, indicating oxidative stress. They also found increased levels of ROS that were associated with decreased levels of antioxidant enzymes and their co-factors.“The results suggest that these antioxidant enzymes can be used as effective therapeutic targets for the treatment of this disease. Also, supplementing patients with substances that possess antioxidant properties could reduce the complications of the disease,” says biochemist Lamia Al-Naama, the lead author of the paper. Substances that decrease the frequency of episodes of red blood cell destruction or employing molecular approaches that can reduce ROS production could alter the course of the disease and the incidence of associated complications, she adds.The sickle cell trait is found in 6.5% of southern Iraqis. The estimated incidence of children born with two sickle cell genes (homozygous for the disease) and thus demonstrating characteristics of the disease is about one in one thousand births.Al-Naama says it is now vital to conduct further research to understand the ethnic and geographic origins of the sickle cell gene present in southern Iraqis. “This would contribute to a better understanding and interpretation of the clinical variety and seriousness of sickle cell anaemia patients [in the region],” she says.One question the team plan to investigate is whether similar observations would be found in patients with different genetic — and thus ethnic and geographical — origins of sickle cell anaemia. They will also research the effects of antioxidant enzymes or their mimics as antioxidant supplements in sickle cell anaemia patients.Other InformationPublished in: QScience.com Highlights, Published by Nature Research for Hamad bin Khalifa University Press (HBKU Press)

description: We treat a problem at the interface of dynamical systems and equilibrium statistical physics. It is well-known that the geometric pressure function $$t\in\mathbb R\mapsto \sup_μ\left\{h_μ(T_2)-t\int\log |dT_2(x)|dμ(x)\right\}$$ of the Chebyshev quadratic map $T_2(x)=1-2x^2$ $(x\in\mathbb R)$ is not differentiable at $t=-1$. We show that this phase transition can be "removed", by an arbitrarily small singular perturbation of the map $T_2$ into Hénon-like diffeomorphisms. A proof of this result relies on an elaboration of the well-known inducing techniques adapted to Hénon-like dynamics near the first bifurcation.

description: The clinical phenotype of 1q21.1 microdeletion syndrome is highly heterogeneous. It is characterized by dysmorphic facial features, microcephaly, and developmental delay. Several congenital defects, including cardiac, ocular, skeletal anomalies, and psychiatric or behavioural abnormalities, have also been described. Here, we report on two siblings with substantial intrafamilial phenotypic variability carrying a heterozygous deletion of the 1q21.1 region spanning a known critical genomic area (∼1.35 Mb). The microdeletion was inherited from the unaffected father. Patients described here show a spectrum of clinical features, a portion of which overlap with those previously reported in patients with 1q21.1 microdeletions. In addition, we review the clinical reports of 66 individuals with this condition. These findings extend and substantiate the current clinical understanding of recurrent copy number variations in the 1q21.1 region.
Entwicklung von Selbsteinschätzung und Leistung beim Üben mit Selbstdiagnosebögen

description: Die Idee hinter den Selbstdiagnosebögen ist es die Verantwortung für das Lernen bei den Lernenden zu fördern und die Nutzung der Übungshasen zu optimieren. Es Üben nicht alle dieselben Inhalte, sondern jeder übt individuell nach seinem eigenen Bedarf. Erfahrungsberichte aus der Praxis bestätigen die Umsetzung dieser Ideen. Sie berichten aber auch von unzureichender Passung von Selbsteinschätzung und Leistung, die sich im Laufe der Verwendung verbessert (Reiff 2008, Achilles 2011). Es stellt sich daher die Frage, wie das Verhältnis von Einschätzung und Leistung zu unterschiedlichen Zeitpunkten ist und wie es sich im Laufe der Zeit verändert.

description: Doctors in Pakistan report the case of a surgical sponge left inside a patient’s body during a medical procedure and only discovered 15 years later.The report, published in the Qatar Medical Journal, describes the case of a 40-year-old woman who visited the Aga Khan University Hospital in Karachi complaining of nausea, loss of appetite, and discomfort in the lower abdominal region.The woman had been experiencing these symptoms for over 10 years. During the past five years, her appetite was reduced, she lost 3 kg in weight and experienced fewer bowel movements.Examining her medical history, the doctors noted that she had given birth three times — twice by natural vaginal delivery, and once by emergency Caesarian section, some 15 years earlier.Her blood tests and urinalysis were normal, so the doctors performed a CT scan of the woman’s abdomen and pelvis that yielded surprising results. The scan showed that the woman bore a rounded mass with thin metallic coils in her lower left abdomen.The doctors then suspected that a surgical sponge had been left inside her body during the C-section surgery. After discussions with the patient and her family, the doctors decided that surgical intervention was necessary to remove the foreign body left behind. A follow-up exam performed one year later showed that the patient had recovered well and remained free of any symptoms.“She initially developed feelings of anger and resentment towards her obstetrician,” says Muhammad Abdul Rehman, lead author of the case study. “She wanted to know if this was a direct mistake of the attending doctor and how it could even take place, [but] as her anger subsided, she realized that this was an unfortunate and rare event, and nothing had been done deliberately.”The first case of the retention of a surgical sponge or other foreign body, called gossypiboma, was described in 1884. It is estimated to occur once in every 1,000 or 1,500 abdominal surgeries. This may be a conservative estimate, however, and it may occur more frequently.It almost always occurs as a result of human error, and is, therefore, preventable. Some researchers are now studying whether the use of barcoded or radiofrequency identification-tagged sponges could reduce its occurrence or prevent it altogether.“The most important measure to avoid such mishaps is to improve communication amongst members of the operating team, especially scrub nurses, technicians and surgeons,” says Abdul Rehman. “Strict adherence to sponge-counting protocols is also important.”Other InformationPublished in: QScience.com Highlights, Published by Nature Research for Hamad bin Khalifa University Press (HBKU Press)
