description: Production of conductive composite electrodes for extracellular recording and stimulation Multielectrode arrays, or MEAs, are increasingly indispensable technologies in bioscience, especially within fundamental neuroscience and cardiac electrophysiology [1]. They generally consist of arrangements of electrodes that allow for the targeting of several sites in parallel within a tissue or cell culture for extracellular recording and stimulation. While commercially available MEAs have many positive features, in particular their biocompatibility, chemical stability and reasonable electrode density, they are often difficult to produce at scale, making them expensive to procure. This high cost and the limited availability of different electrode configurations makes it difficult for many research labs to conduct extensive trials in parallel, slowing down the rate of progress in the biosciences. Here, an alternative method of fabricating MEAs will be described. This method utilizes the flexibility of additive manufacturing technologies, specifically Photopolymer Inkjet Printing or PolyJet printing, to create complex electrode array channels that are filled with a conductive composite comprised of silver paste dispersed in α-terpineol to form the electrodes. By way of experimental validation, the MEAs produced using this method were subsequently used to stimulate nervous tissue ex vivo. Spira, Micha E., and Aviad Hai.

description: Because of the pandemia, the workshop on ``Structure-Preserving Discretizations for Nonlinear Systems of Hyperbolic, Involution-Constrained Partial Differential Equations on Manifolds" could not be realized in the usual format or in the new hybrid format. Only one participant (P. Helluy) was able to physically come the MFO. He worked remotely with C. Klingenberg on a structure preserving time integration for kinetic models. This allows to building efficient schemes for solving conservation laws. A preprint describing this work, with applications to MHD, can be found here: \texttt{https://hal.archives-ouvertes.fr/hal-02965967}. Meanwhile, C. Klingenberg organized a remote seminar on the topics of the workshop. From September 2020 to December 2020, 13 talks were given online by participants to the workshop and other personalities.
Mesoscopic magnetoelectric effect in chaotic quantum dots

description: The magnitude of the inverse Faraday effect (IFE), a static magnetization due to an ac electric field, can be strongly increased in a mesoscopic sample, sensitive to time-reversal symmetry (TRS) breaking. Random rectification of ac voltages leads to a magnetization flux, which can be detected by an asymmetry of Hall resistances in a multi-terminal setup. In the absence of applied magnetic field through a chaotic quantum dot the IFE scale, quadratic in voltage, is found as an analytic function of the ac frequency, screening, and coupling to the contacts and floating probes, and numerically it does not show any effect of spin-orbit interaction. Our results qualitatively agree with a recent experiment on TRS-breaking in a six-terminal Hall cross.

How does India build in its border states? A case study of statebuilding in the NEFA region( 1950-1970)

Year: 2023
Subjects: subject: Statebuilding

description: State building in India’s borders has been a complicated and dynamic process. In this paper I will use the cases of NEFA (North-east Frontier Agency), the erstwhile Arunachal Pradesh, and Nagaland to argue that India approaches state building differently in both cases. Even though both had similar interactions with the British colonial state, the priorities of the newly independent India shifted as it started to secure its borders. State building outcomes look different when there is ethnic mobilization against the state, India finds it harder to build in its borders as it faces resistance. This can change drastically when there is an internationally significant border where the other side seeks to stake a claim in the land. State building will be more effective, and India is able to deliver on welfare schemes. This paper offers a theory of state building by India in its borderlands and looks at its effectiveness. The postcolonial state building process and the accompanying violence shifted the state building and national integration outcomes of both the states drastically
Vector Autoregressive Models With Measurement Errors for Testing Ganger Causality

Year: 2009
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: This paper develops a method for estimating parameters of a vector autoregression (VAR) observed in white noise. The estimation method assumes the noise variance matrix is known and does not require any iterative process. This study provides consistent estimators and shows the asymptotic distribution of the parameters required for conducting tests of Granger causality. Methods in the existing statistical literature cannot be used for testing Granger causality, since under the null hypothesis the model becomes unidentifiable. Measurement error effects on parameter estimates were evaluated by using computational simulations. The results show that the proposed approach produces empirical false positive rates close to the adopted nominal level (even for small samples) and has a good performance around the null hypothesis. The applicability and usefulness of the proposed approach are illustrated using a functional magnetic resonance imaging dataset.

Variational Methods for Evolution (hybrid meeting)

Publisher: name: Zürich : EMS Publ. House
Year: 2020
Subjects: subject: Konferenzschrift
subject: 510

description: Variational principles for evolutionary systems take advantage of the rich toolbox provided by the theory of the calculus of variations. Such principles are available for Hamiltonian systems in classical mechanics, gradient flows for dissipative systems, but also time-incremental minimization techniques for more general evolutionary problems. The new challenges arise via the interplay of two or more functionals (e.g. a free energy and a dissipation potential), new structures (systems with nonlocal transport, gradient flows on graphs, kinetic equations, systems of equations) thus encompassing a large variety of applications in the modeling of materials and fluids, in biology, in multi-agent systems, and in data science. This workshop brought together a broad spectrum of researchers from calculus of variations, partial differential equations, metric geometry, and stochastics, as well as applied and computational scientists to discuss and exchange ideas. It focused on variational tools such as minimizing movement schemes, optimal transport, gradient flows, and large-deviation principles for time-continuous Markov processes, $\Gamma$-convergence and homogenization.

description: This mini-workshop focused on chromatic phenomena and duality as unifying themes in algebra, geometry, and topology. The overarching goal was to establish a fruitful exchange of ideas between experts from various areas, fostering the study of the local and global structure of the fundamental categories appearing in algebraic geometry, homotopy theory, and representation theory. The workshop started with introductory talks to bring researches from different backgrounds to the same page, and later highlighted recent progress in these areas with an emphasis on the interdisciplinary nature of the results and structures found. Moreover, new directions were explored in focused group work throughout the week, as well as in an evening discussion identifying promising long-term goals in the subject. Topics included support theories and their applications to the classification of localizing ideals in triangulated categories, equivariant and homotopical enhancements of important structural results, descent and Galois theory, numerous notions of duality, Picard and Brauer groups, as well as computational techniques.

Lefschetz Properties in Algebra, Geometry and Combinatorics (hybrid meeting)
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2020
Subjects: subject: Konferenzschrift
subject: 510

description: The themes of the workshop are the Weak Lefschetz Property - WLP - and the Strong Lefschetz Property - SLP. The name of these properties, referring to Artinian algebras, is motivated by the Lefschetz theory for projective manifolds, initiated by S. Lefschetz, and well established by the late 1950's. In fact, Lefschetz properties of Artinian algebras are algebraic generalizations of the Hard Lefschetz property of the cohomology ring of a smooth projective complex variety. The investigation of the Lefschetz properties of Artinian algebras was started in the mid 1980's and nowadays is a very active area of research. Although there were limited developments on this topic in the 20th century, in the last years this topic has attracted increasing attention from mathematicians of different areas, such as commutative algebra, algebraic geometry, combinatorics, algebraic topology and representation theory. One of the main features of the WLP and the SLP is their ubiquity and the quite surprising and still not completely understood relations with other themes, including linear configurations, interpolation problems, vector bundle theory, plane partitions, splines, $d$-webs, differential geometry, coding theory, digital image processing, physics and the theory of statistical designs, etc. among others.

description: (Abridged) We complete the census of nuclear X-ray activity in 100 early type Virgo galaxies observed by the Chandra X-ray Telescope as part of the AMUSE-Virgo survey, down to a (3sigma) limiting luminosity of 3.7E+38 erg/s over 0.5-7 keV. The stellar mass distribution of the targeted sample, which is mostly composed of formally `inactive' galaxies, peaks below 1E+10 M_Sun, a regime where the very existence of nuclear super-massive black holes (SMBHs) is debated. Out of 100 objects, 32 show a nuclear X-ray source, including 6 hybrid nuclei which also host a massive nuclear cluster as visible from archival HST images. After carefully accounting for contamination from nuclear low-mass X-ray binaries based on the shape and normalization of their X-ray luminosity function, we conclude that between 24-34% of the galaxies in our sample host a X-ray active SMBH (at the 95% C.L.). This sets a firm lower limit to the black hole occupation fraction in nearby bulges within a cluster environment. At face value, the active fraction -down to our luminosity limit- is found to increase with host stellar mass. However, taking into account selection effects, we find that the average Eddington-scaled X-ray luminosity scales with black hole mass as M_BH^(-0.62^{+0.13}_{-0.12}), with an intrinsic scatter of 0.46^({+0.08}_{-0.06}) dex. This finding can be interpreted as observational evidence for `down-sizing' of black hole accretion in local early types, that is, low mass black holes shine relatively closer to their Eddington limit than higher mass objects. As a consequence, the fraction of active galaxies, defined as those above a fixed X-ray Eddington ratio, decreases with increasing black hole mass.

Publisher: name: University of British Columbia
Year: 2011

description: An intermediate image beta ray spectrometer has been constructed using the two magnets from two thin lens spectrometers, previously in use in this laboratory. A surface barrier type detector replaces the scintillator -photomultiplier arrangement used before, resulting in greatly reduced background noise. The performance of this spectrometer is considerably better than the two it replaces, having resolutions of 0.51 %, 0.7 %, 0.94 % and 2.2 % at transmissions of 0.49 %, 0.96 %, 1.26 % and 5.96 %. The normal energy range is from 25 Kev, to 1.5 Mev but it can be extended to 2.0 Mev with some loss of transmission. An examination of the beta spectrum of Eu¹⁵⁴ was carried out with this instrument. A Kurie plot of the continuum has been made and six primary beta groups found with end point energies of 1.866 Mev, 1.198 Mev , 0.976 Mev , 0.843 Mev , 0.579 Mev , and 0.274 Mev with relative abundances of 10.8 %. 0.67 %, 4.6 %, 17.0 %, 37.8 %, and 29.1 %. Both end-points and relative intensities are in excellent agreement with data from other workers.
Stochastic Processes under Constraints (hybrid meeting)

Year: 2020
Subjects: subject: Konferenzschrift
subject: 510

description: The analysis of random processes under various constraints and conditions has been a central theme in the theory of stochastic processes, which links together several mathematical subdisciplines. The connection between potential theory and a certain type of conditioning of Markov processes via Doob's h-transform can be seen as a classical highlight. The last decades have seen further exciting and highly interesting developments which are related to the title of the workshop such as the analysis of persistence exponents for various classes of processes and various types of penalization problems. Many of these problems are rooted in questions from statistical mechanics. The workshop aims to investigate the topic stochastic processes under constraints from all these different perspectives.

description: We aim to characterise the properties of the stellar clusters in the Milky Way. Utilising an expectation-maximisation method we determined that the cluster FSR0358, originally discovered by J.D.Kirkpatrick, is the most likely real cluster amongst the cluster candidates from Froebrich et al.. Here we present new deep high resolution near infrared imaging of this object obtained with UKIRT. The analysis of the data reveals that FSR0358 (Kirkpatrick1) is a 5+-2Gyr old open cluster in the outer Milky Way. Its age, metallicity of Z=0.008 and distance from the Galactic Centre of 11.2kpc are typical for the known old open galactic clusters. So far six of the FSR cluster candidates have been identified as having an age above 5Gyr. This shows the significance of this catalogue in enhancing our knowledge of the oldest open clusters in the Galaxy.

description: We present a study of the propagation of higher-order spatial modes in a waveguided parametric down-conversion photon pair source. Observing the multimode photon pair spectrum from a periodically poled KTiOPO$_4$ waveguide allowed us to isolate individual spatial modes through their distinctive spectral properties. We have measured directly the spatial distribution of each mode of the photon pairs, confirming the findings of our waveguide model, and demonstrated by coincidence measurements that the total parity of the modes is conserved in the nonlinear interaction. Furthermore, we show that we can combine the advantages of a waveguide source with the potential to generate spatially entangled photon pairs as in bulk crystal down-converters.

description: Studies of interlayer transport in layered metals have generally made use of zero temperature conductivity expressions to analyze angle-dependent magnetoresistance oscillations (AMRO). However, recent high temperature AMRO experiments have been performed in a regime where the inclusion of finite temperature effects may be required for a quantitative description of the resistivity. We calculate the interlayer conductivity in a layered metal with anisotropic Fermi surface properties allowing for finite temperature effects. We find that resistance maxima are modified by thermal effects much more strongly than resistance minima. We also use our expressions to calculate the interlayer resistivity appropriate to recent AMRO experiments in an overdoped cuprate which led to the conclusion that there is an anisotropic, linear in temperature contribution to the scattering rate and find that this conclusion is robust.

The State of Francis Fukuyama
Creators: name: Nelson, Hank
Publisher: name: Canberra, ACT: Coral Bell School of Asia Pacific Affairs, College of Asia and the Pacific, The Australian National University
Year: 2006

description: Professor Francis Fukuyama, currently Bernard L Schwartz Professor of International Political Economy at Johns Hopkins University, was born in Chicago in 1952, and has a BA from Cornell and a doctorate in political science from Harvard. He has worked with the RAND Corporation, the Department of State specialising on the Middle East, and continues to serve on several significant boards such as the President’s Council on Bioethics and the National Endowment for Democracy. Something of the range of his interests can be gauged from the fact that he has written monographs on Russia and the Third World, the consequences of the biotechnology revolution, and social capital. He became widely known with the publication of The End of History and the Last Man in 1992. Translated into many languages, the head of bestseller lists and awarded major international prizes, The End of History and the Last Man provoked popular and academic debates; but his two most recent books, State Building: Governance and World order in the TwentyFirst Century (2004) and After the Neocons: America at the Crossroads (2006) have more immediate relevance to Australia. His shift from identifying as a neoconservative to asserting that neoconservatism was ‘something’ he ‘could no longer support’, has been reported widely in Australia. He had contributed to the neoconservatist underpinning of the war in Iraq and he had joined the initial celebration at the fall of Sadam Hussein, but he has concluded that the American theoretical justification for the war was wrong and its execution incompetent, and he has called for a new direction in American foreign policy, a ‘Realistic Wilsonianism’. While Fukuyama’s changing evaluation of the arguments of his one-time neocon colleagues has illuminated major issues about American policy and the war in Iraq, his general thinking about failed or weak states and foreign intervention has received less attention in Australia. And it is those considerations that have implications for Australian policies in East Timor, Bougainville, Papua New Guinea, Solomon Islands and the other islands where Australia has primary responsibility for any external interventions requiring personnel and cash. Where there have been debates in Australia, they have tended to be concerned with the immediate and practical, not the long-term and theoretical, but as Fukuyama and others have demonstrated, much foreign aid and intervention has been determined by theoretical assumptions that are unproven or false

Year: 2023

description: Background— Thrombosis and thromboembolism has been linked to Coronavirus Disease 2019 (COVID-19), andacute ischemic stroke has been reported in several patients.Case Description— A patient with recent COVID-19 occurred 13 days prior to admission, presented with acuteischemic stroke with an initial National Institutes of Health stroke scale (NIHSS) score of 36. Computerized to-mography angiogram demonstrated occlusion of the basilar artery with mismatch on the cerebral perfusion analysis.He was successfully treated with aspiration thrombectomy and NIHSS score improved to 1 on the second day postprocedure. He made a full recovery and has returned to his normal activities (modified Rankin Scale 0 at discharge).Serological studies showed elevated IgM and IgG anticardiolipin antibodies that remained elevated 7 weeks after theinitial infection.Conclusions— Basilar artery thrombosis can be associated with COVID-19 and may be mediated through elevatedanticardiolipin antibodies.
Discovery of a Luminous Blue Variable with an Ejection Nebula Near the Quintuplet Cluster

description: We report on the discovery of a luminous blue variable (LBV) lying ~7 pc in projection from the Quintuplet cluster. This source, which we call LBV G0.120-0.048, was selected for spectroscopy owing to its detection as a strong source of Paschen-alpha excess in a recent narrowband imaging survey of the Galactic center region with HST/NICMOS. The K-band spectrum is similar to that of the Pistol Star and other known LBVs. The new LBV was previously cataloged as a photometric variable star, exhibiting brightness fluctuations of up to ~1 mag between 1994 and 1997, with significant variability also occurring on month-to-month time scales. The luminosity of LBV G0.120-0.048, as derived from 2MASS photometry, is approximately equivalent to that of the Pistol Star. However, the time-averaged brightness of LBV G0.120-0.048 between 1994 and 1997 exceeded that of the Pistol Star; LBV G0.120-0.048 also suffers more extinction, which suggests that it was intrinsically more luminous in the infrared than the Pistol Star between 1994 and 1997. Paschen-alpha images reveal a thin circular nebula centered on LBV G0.120-0.048 with a physical radius of ~0.8 pc. We suggest that this nebula is a shell of ejected material launched from a discrete eruption that occurred between 5000 and 10,000 years ago. Because of the very short amount of time that evolved massive stars spend in the LBV phase, and the close proximity of LBV G0.120-0.048 to the Quintuplet cluster, we suggest that this object might be coeval with the cluster and may have once resided within it.

description: This is a continuation of our preceding paper devoted to signatures of quantum chaos in the geometric collective model of atomic nuclei. We apply the method by Peres to study ordered and disordered patterns in quantum spectra drawn as lattices in the plane of energy vs. average of a chosen observable. A good qualitative agreement with standard measures of chaos is manifested. The method provides an efficient tool for studying structural changes of eigenstates across quantum spectra of general systems.

Ernst Juengers "Innere Emigration"
Creators: name: Juergens, Thorsten Arnd
Publisher: name: University of British Columbia
Year: 2011

description: Diese These ist ein Versuch, Ernst Juengers innere Emigration waehrend der Hitlerjahre zu behandeln, um damlt einen Beitrag zum Verstaendnis und zur Klaerung des Begriffs "innere Emigration" zu bringen. Im ersten Kapitel wird der Begriff der inneren Emigration im allgemeinen besprochen, die Entstehungsgeschlchte des Konzepts und die Moeglichkeit einer unabhaengigen Existenz im totalitaeren dritten Reich. Nach dieser Einfuehrung wendet sich die Diskussion den Werken Juengers zu. Die Werke, die gewaehlt wurden, sind folgende: das Essay Das abenteuerliche Herz, beide Fassungen (I929, 1935), der Roman Auf den Mar- morklippen (1942), die Tagebuecher Strahlungen einschl. dem Nachkriegstagebuch Jahre der Okkupation und die Essays Ueber die Linie (I950) und Per Waldgang (1951). Durch die Auswahl der Werke wurde versucht, ein zusammenhaengendes Bild von Juengers Gedankenwelt von der Vorhitlerzeit, durch die Hitlerzeit bis in die Spaetnachkriegszeit zu geben. Hieraus wird erkenntllch, dass Juenger schon vor der Hitlerdiktatur ein verfremdeter Individualist der verinnerlichung und ein Pessimist in Hinslcht auf die Kulturentwicklung war. Seine introvertierte Existenz und seine Gedankenwelt erleichtern den Gang in die innere Emigration, die die schon zuvor bestehenden Veranlagungen nur verstaerkte. Waehrend der Hitlerjahre waechst Juengers intellektueller Widerstand zu neuen Formen. Doch werden die Erlebnisse an der Ostfront zu einem Wendepunkt, denn hier erlischt in ihm im Angesicht der Greueltaten beinahe der musische Mensch. Anstatt zu kapitulieren, wendet sich Juenger zum Gegenkampf und geht durch Der Friede (1944) zum aktiven geistigen Widerstand ueber, Auch in der Nachkriegszeit blieb Juenger ein intellektueller Einzelgaenger, denn die Technokratie in Gestalt der Atombombe und der Nihilismus bleiben eine totalitaere Gefahr fuer das Individuum. Juengers Schicksal war das eines hohen Geistes, der In einer ihm fremden Zeitepoche des kulturellen Verfalls lebte. Die Hitlerdiktatur sowie die innere Emigration waren nur Steigerungen der allgemeinen Entwicklung der faktischen Umwelt, dem Niedergang einer Kulturepoche; von ihr wendet Juenger seinen Blick ab und erkennt einen metahistorischen Weltenplan der Urmaechte. Juenger relativiert also die totalitaere Umwelt durch sein metaphysisches Wertbewusstsein und nur aus diesem heraus kann Juengers innere Emigration beurteilt werden.

description: We present results of comprehensive seismic modelling of the B-type main-sequence pulsator $ν$ Eridani, which consists in parallel fitting of the pulsational frequencies and corresponding values of the complex, nonadiabatic parameter $f$, defined by the bolometric flux perturbation. This kind of studies, which we call {\it complex asteroseismology}, provides a unique test of stellar opacities. Our results indicate a preference for the OPAL data.

External gates and transport in biased bilayer graphene

description: We formulate a theory of transport in graphene bilayers in the weak momentum scattering regime in such a way as to take into account contributions to the electrical conductivity to leading and next-to-leading order in the scattering potential. The response of bilayers to an electric field cannot be regarded as a sum of terms due to individual layers. Rather, interlayer tunneling and coherence between positive- and negative-energy states give the main contributions to the conductivity. At low energies, the dominant effect of scattering on transport comes from scattering within each energy band, yet a simple picture encapsulating the role of collisions in a set of scattering times is not applicable. Coherence between positive- and negative-energy states gives, as in monolayers, a term in the conductivity which depends on the order of limits. The application of an external gate, which introduces a gap between positive- and negative-energy states, does not affect transport. Nevertheless the solution to the kinetic equation in the presence of such a gate is very revealing for transport in both bilayers and monolayers.

description: Geoscience Australia has a large holding of surface sediment samples, such as stream and overbank sediments, from geochemical surveys conducted over more than 50 years across the Australian continent. Geochemical data from these surface materials are of national importance as they can contribute significantly to establishing geochemical environmental baselines and their use in land management, as well as aiding in the discovery of new mineral deposits. Samples from these legacy surveys provide valuable insights into areas of Australia that are remote, difficult to access, or have since been developed. The age of a large number of these surveys, however, means that the original results included data for a smaller range of chemical elements, typically with poorer analytical precision and accuracy than those of modern surveys. This small range of chemical elements also typically doesn’t include important elements for modern use, such as critical minerals (i.e. Co, Bi, REEs), which are increasing in their importance. As part of Geoscience Australia’s Exploring for the Future program, a collection of over 9000 samples from these surveys was reanalysed using modern analytical techniques for a suite of 60 chemical elements. These samples cover several regions within Australia, including Kakadu, Cape York, the Mount Isa region, and near the Canberra region. The new analytical data maximise the value of the historical geochemical surveys and will provide new insights into the mineral potential of these regions and improve the quality of geochemical environmental baselines.
This data release includes: 1) information on the surveys and their samples; 2) quality assurance results; 3) a discussion of sample preparation and analytical methods used; 4) results for total content geochemistry (XRF and LA-ICP-MS); and 5) individual element maps for each of the regions for preliminary interpretation of the data.
Acquisition and release of this dataset forms part of a larger program aimed at creating a levelled geochemical baseline for the whole Australia (Main and Champion, 2020).

A compositional link between rocky exoplanets and their host stars
Creators: name: Adibekyan, Vardan
Publisher: name: Zenodo

description: Young stars and planets both grow by accreting material from the proto-stellar disks. Planetary structure and formation models assume a common origin of the building blocks, yet, thus far, there is no direct observational evidence correlating the composition of rocky planets to their host stars. Here we present evidence of a tight chemical link between rocky planets and their host stars. The iron-mass fraction of the most precisely characterized rocky planets is compared to that of their building blocks, as inferred from the atmospheric composition of their host stars. We find a clear and statistically significant correlation between the two. Our results explain the deviations from the Earth-like densities of planets which have been previously considered as anomalous. We also find that on average the iron-mass fraction of planets is higher than that of the primordial iron content in the planet building blocks, owing to the disk-chemistry and planet formation processes. Finally, our results provide some hints that the giant impact alone is not responsible for the high-densities of super-Mercuries. We conclude that rocky planet composition depends on the chemical composition of the proto-planetary disk and contains signatures about planet formation processes. I propose an oral contribution to speak about these very recent results which are accepted for publication in Science.

Compressed sensing reconstruction of a string signal from interferometric observations of the cosmic microwave background

description: We propose an algorithm for the reconstruction of the signal induced by cosmic strings in the cosmic microwave background (CMB), from radio-interferometric data at arcminute resolution. Radio interferometry provides incomplete and noisy Fourier measurements of the string signal, which exhibits sparse or compressible magnitude of the gradient due to the Kaiser-Stebbins (KS) effect. In this context the versatile framework of compressed sensing naturally applies for solving the corresponding inverse problem. Our algorithm notably takes advantage of a model of the prior statistical distribution of the signal fitted on the basis of realistic simulations. Enhanced performance relative to the standard CLEAN algorithm is demonstrated by simulated observations under noise conditions including primary and secondary CMB anisotropies.
