Year: 2022

description: Tendo em vista que na Ciência Aberta participam diferentes atores, emerge a necessidade de verificar como o profissional bibliotecário entende essa nova forma de fazer a ciência acontecer. O profissional bibliotecário configura-se como um dos facilitadores entre o pesquisador e a Ciência Aberta. No cenário acadêmico, fica evidente que o compartilhamento, o reuso e a forma colaborativa de fazer ciência são as maiores vantagens da Ciência Aberta. Sendo assim, esta investigação compreende a dimensão da Ciência Aberta e o bibliotecário universitário, a fim de entender como este profissional percepciona e contribui para a Ciência Aberta. Através de um estudo de caso, os 73 bibliotecários do Instituto Federal de Educação, Ciência e Tecnologia de São Paulo (IFSP) responderam a um inquérito por questionário com perguntas relacionadas à Ciência Aberta e a análise documental, a partir do site das bibliotecas do IFSP, foi outro instrumento utilizado na recolha dos dados. A investigação é de natureza exploratória com uma abordagem qualitativa. Verificou-se que a maior parte dos bibliotecários tem conhecimento do que é a Ciência Aberta. O acesso aberto e os dados abertos são os termos mais conhecidos quando se menciona a Ciência Aberta. No entanto, os bibliotecários reclamam maior apoio institucional na sua implementação. Diante dessa realidade, torna-se imprescindível repensar a ação dos bibliotecários e das instituições para um trabalho colaborativo em prol da Ciência Aberta.

Accountability in archival science
Creators: name: Parkinson, Jane
Publisher: name: University of British Columbia
Year: 2008

description: Laws proclaiming freedom of information have been introduced in many countries in the past twenty years, creating familiarity with the idea that governments can achieve accountability by providing public access to current records. Some archivists hold the view that the preservation and accessibility of non-current records in archival repositories is similarly related to the principle of accountability; however this idea is not widely diffused and even less accepted, primarily because the concept of accountability is imprecise and has not been integrated into archival theory. This thesis analyses the concept of accountability and demonstrates its relevance in the context of archival science. It provides an explanation of the relationship between accountability and record keeping, which is found in an agent's obligation to create, preserve and provide access to records in order to account to the source of authority for the actions documented by the records. Also, it shows the connection between the concept of accountability and other administrative, legal, political and ethical values, a connection which is found in the complex and sometimes abstract social relationships that involve delegation of authority. Then, the thesis proceeds to examine the appearance of the concept of accountability in archival literature on issues of preservation, ownership, accessibility and management of records, and analyses it in relation to archival as well as administrative, political or legal concerns. Finally, the accountability owed by archivists is examined, through analysis of the claims made by repositories, users and the archival profession for authority over archives and theircare. The thesis proposes that recognition of the importance for archives of meeting accountability obligations depends on the general understanding of records as evidence of actions, and acknowledgement of an organizational and public interest in their preservation.

description: An approach to determine the kinetic beam energy at the $10^{-5}$ level is presented, which corresponds to an improvement by more than one order of magnitude compared to conventional methods. Particularly, collinear fluorescence and resonance ionization spectroscopy measurements on rare isotope beams, where the beam energy is a major contribution to the uncertainty, can benefit from this method. The approach is based on collinear spectroscopy and requires no special equipment besides a wavelength meter, which is commonly available. Its advent is demonstrated in a proof-of-principle experiment on a Ni beam. In preparation for the energy measurement, the rest-frame transition frequencies of the $3d^9 4s\;^3\mathrm{D}_3 \rightarrow 3d^9 4p\;^3\mathrm{P}_2$ transitions in neutral nickel isotopes have been identified to be $ν_0(^{58}\mathrm{Ni})=850\,343\,678\,(20)$ MHz and $ν_0(^{60}\mathrm{Ni})=850\,344\,183\,(20)$ MHz.

description: The question whether quiescent black hole X-ray binaries are capable of powering relativistic outflows is addressed by means of simultaneous radio/X-ray observations of a nearby system steadily emitting X-rays below 1e-8 times the Eddington luminosity. The robust detection of a radio counterpart suggests that a synchrotron emitting outflow is being powered by this system, even though its degree of collimation remains unknown, and hard to investigate. With the inclusion of the A0620-00 data, the non linear radio/X-ray correlation for hard state black hole X-ray binaries appears to hold down to very low quiescent luminosities. However, an increasing number of outliers is being found at higher luminosities, questioning the universality of such correlation, or at least its normalization.

description: We have measured the thermal conductivity of the one-dimensional (1D) S=1/2 Heisenberg antiferromagnetic spin system of Sr2Cu1-xPdxO3 single crystals including nonmagnetic impurities of Pd2+. It has been found that the mean free path of spinons along the 1D spin chain at low temperatures is very close to the average length of finite spin chains between spin defects estimated from the magnetic susceptibility measurements. This proves that the thermal conduction due to spinons at low temperatures in Sr2CuO3 is ballistic as theoretically expected [Zotos et al.: Phys. Rev. Lett. 55 (1997) 11029].

Στην παρούσα ανασκόπηση, έγινε η προσπάθεια να συγκεντρωθούν όλα τα στοιχεία που αφορούν την υπόθεση της Νόσου Alzheimer ως διαβήτη τύπου 3 και των κοινών παθοφυσιολογικών μηχανισμών μεταξύ της ΝΑ και του ΣΔ2. Διερευνήθηκαν ενδελεχώς οι βιβλιογραφικές βάσεις δεδομένων PubMed και Google Scholar. Το χρονικό όριο για την αναζήτηση τέθηκε μεταξύ 2000 και 2020 και η αναζήτηση στις βιβλιογραφικές βάσεις δεδομένων είχε διάρκεια από τον Νοέμβριο του 2019 έως τον Φεβρουάριο του 2020. Όπως φαίνεται από τις έρευνες, η ΝΑ μοιράζεται πολλά κοινά στοιχεία με ασθένειες που αφορούν την αντίσταση στην ινσουλίνη, όπως η διαταραχή στη σηματοδότηση της ινσουλίνης, η νευροφλεγμονή, το οξειδωτικό στρες, τα τελικά προϊόντα προχωρημένης γλυκοζυλίωσης, η μιτοχονδριακή δυσλειτουργία και το μεταβολικό σύνδρομο. Επίσης, υπάρχουν δεδομένα ερευνών που παρουσιάζουν βελτιώσεις με την χορήγηση αντιδιαβητικών φαρμάκων σε ασθενείς με ΝΑ, όπως η ενδορινική ινσουλίνη, η μετφορμίνη, τα ινκρετινομιμητικά και οι θειαζολιδινεδιόνες (PPARγ αγωνιστές). Επομένως, η ΝΑ θα μπορούσε να θεωρηθεί ως μια μεταβολική νόσος που προκαλείται από την αντίσταση στην ινσουλίνη του εγκεφάλου.
description: Globally, the incidence of Type 2 Diabetes and Alzheimer’s Disease epidemics is growing rapidly and has huge financial and emotional costs. In the present review, an attempt was made to gather all the data concerning the case of Alzheimer’s Disease as type 3 diabetes and the common pathophysiological mechanisms between Alzheimer’s Disease and Type 2 Diabetes. The PubMed and Google Scholar bibliographic databases were thoroughly researched. The time limit for the search was set between 2000 and 2020 and the search in the bibliographic databases lasted from November 2019 to February 2020. As can be seen from the surveys, AD shares many common elements with diseases related to insulin resistance, such as insulin signaling disorder, neuroinflammation, oxidative stress, advanced glycosylation end products, mitochondrial dysfunction, and metabolic syndrome. There are also research data showing improvements in the administration of antidiabetic drugs to patients with AD, such as intranasal insulin, metformin, incretinomimetics, and thiazolidinediones (PPARγ agonists). Therefore, AD could be considered as a metabolic disease caused by insulin resistance in the brain.

description: The incidence of hepatocellular carcinoma (HCC) keeps rising year by year, and became the second leading cause of cancer-related death. Some studies have found that liraglutide, a GLP-1 analog, may decrease the tumor cells proliferation. Due to this, the aim of this work is to investigate the antiproliferative potential of exenatide, another GLP-1 analog. Cell proliferation was assessed by direct count with Trypan blue dye exclusion. Flow cytometry was used to determinate autophagy and nuclear staining. Morphometric analysis was used to verify senescence and apoptosis. The mechanism that induced cell growth inhibition was analyzed by Western Blot. Treatment with exenatide significantly decreases cell proliferation and increases autophagy, both in relation to control and liraglutide. In addition, mTOR inhibition was greater in cells treated with exenatide. In relation to chronic treatment, exenatide does not allow cellular regrowth by preventing some resistance mechanism that the cells can acquire. These results suggest that exenatide has a potent anti-proliferative activity via mTOR modulation and, among the GLP-1 analogs tested, could be in the future an alternative for HCC treatment.

description: We present a Chandra-LETGS observation of the Seyfert 1 galaxy Mrk 279. This observation was carried out simultaneously with HST-STIS and FUSE, in the context of a multiwavelength study of this source. The Chandra pointings were spread over ten days for a total exposure time of ~360 ks. The spectrum of Mrk279 shows evidence of broad emission features, especially at the wavelength of the OVII triplet. We quantitatively explore the possibility that this emission is produced in the broad line region (BLR). We modeled the broad UV emission lines seen in the FUSE and HST-STIS spectra following the ``locally optimally emitting cloud" approach. We find that the X-ray lines luminosity derived from the best fit BLR model can match the X-ray features, suggesting that the gas producing the UV lines is sufficient to account also for the X-ray emission. The spectrum is absorbed by ionized gas whose total column density is ~5x10^{20} cm^{-2}. The absorption spectrum can be modeled by two distinct gas components (log xi ~ 0.47 and 2.49, respectively) both showing a significant outflow velocity. However, the data allow also the presence of intermediate ionization components. The distribution of the column densities of such extra components as a function of the ionization parameter is not consistent with a continuous, power law-like, absorber, suggesting a complex structure for the gas outflow for Mrk 279 (abridged).

Theoretical planetary mass spectra - a predition for COROT

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: The satellite COROT will search for close-in exo-planets around a few thousand stars using the transit search method. The COROT mission holds the promise of detecting numerous exo-planets. Together with radial velocity follow-up observations, the masses of the detected planets will be known. We have devised a method for predicting the expected planetary populations and compared it to the already known exo-planets. Our method works by looking at all hydrostatic envelope solutions of giant gas planets that could possibly exist in arbitrary planetary nebulae and comparing the relative abundance of different masses. We have completed the first such survey of hydrostatic equilibria in an orbital range covering periods of 1 to 50 days. Statistical analysis of the calculated envelopes suggests division into three classes of giant planets that are distinguished by orbital separation. We term them classes G (close-in), H, and J (large separation). Each class has distinct properties such as a typical mass range. Furthermore, the division between class H and J appears to mark important changes in the formation: For close-in planets (classes G and H) the concept of a critical core-mass is meaningless while it is important for class J. This result needs confirmation by future dynamical analysis.

description: A microscopic theory is presented for the observed electronic disorder in superconducting Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$. The essential phenomenology is shown to be consistent with the existence of two types of interstitial oxygen dopants: those serving primarily as charge reserviors and those close to the apical plane contributing both carriers and electrostatic potential to the CuO$_2$ plane. The nonlinear screening of the latter produces nanoscale variations in the doped hole concentration, leading to electronic inhomogeneity. Based on an unrestricted Gutzwiller approximation of the extended t-$J$ model, we provide a consistent explanation of the correlation between the observed dopant location and the pairing gap and its spatial evolutions. We show that the oxygen dopants are the primary cause of both the pairing gap disorder and the quasiparticle interference pattern.

Mathematical modelling of the onset of transformation from austenite to pearlite under non-continuous cooling conditions
Creators: name: Pham, Tri T.
Publisher: name: University of British Columbia
Year: 2008

description: The temperature at which a new phase forms is an important parameter in the genesis of final microstructure. For diffusional transformation processes, prediction of this temperature on cooling, until now, relied upon empirical equations which are based on the cooling rate or degree of undercooling. To develop a method that is capable of predicting the onset of transformation in the steel, applicable to industrial processing conditions, a theoretical study has been conducted to critically examine the consequences and implications of the Scheil additivity rule in relation to the incubation of the austenite decomposition. An "ideal" isothermal transformation curve for the start of transformation from austenite to pearlite has been developed based on the assumption of the consumed fractional incubation time being additive. The curve is characteristic of the chemistry and the austenite grain size of the steel. A mathematical relationship between the experimental time to the start of transformation and the ideal incubation time was quantified, and two methods for deriving an "ideal" T77' curve from the controlled cooling experiments were established in this study. The derived "ideal" T77' curve was used for predicting the start of transformation from austenite to pearlite for three different cooling conditions; namely, continuous, semi-continuous and non-continuous cooling conditions. The predictions were consistent in all cases and compared favourably against other methods which have been employed frequently frequently to estimate the transformation start temperature for non-isothermal conditions.

description: We solve time-harmonic Maxwell's equations in anisotropic, spatially homogeneous media in intersections of $L^p$-spaces. The material laws are time-independent. The analysis requires Fourier restriction-extension estimates for perturbations of Fresnel's wave surface. This surface can be decomposed into finitely many components of the following three types: smooth surfaces with non-vanishing Gaussian curvature, smooth surfaces with Gaussian curvature vanishing along one-dimensional submanifolds, but without flat points, and surfaces with conical singularities. Our estimates are based on new Bochner-Riesz estimates with negative index for non-elliptic surfaces.

description: We find the model completion of the theory modules over $A$, where $A$ is a finitely generated commutative algebra over a field $K$. This is done in a context where the field $K$ and the module are represented by sorts in the theory, so that constructible sets associated with a module can be interpreted in this language. The language is expanded by additional sorts for the Grassmanians of all powers of $K^n$, which are necessary to achieve quantifier elimination. The result turns out to be that the model completion is the theory of a certain class of ``big'' injective modules. In particular, it is shown that the class of injective modules is itself elementary. We also obtain an explicit description of the types in this theory.

description: This essay deals with the integration of the Church of the Ionian Islands into the Autocephalous Church of Greece. The historical and political events concerning the course of the Ionian Islands during the Venetian rule are presented in a summary with references to the 11th and 12th centuries up to the final Union of the Islands with the rest of Greece in 1864. Initially the institutions of the Archpriests and the Holy Order are analyzed. Furthermore the period of the Latin rule in the Ionian Islands is presented as well as the relations between the Latin clergy and the Orthodox population and also the period of the British protectorate presence. The official recognition of the Church of Greece as Autocephalous by means of the Patriarchal and Synodic Volume 1850 follows and finally the complete Union of the Church of the Ionian Islands occurring in the year of 1866.
Rotation numbers of invariant manifolds around unstable periodic orbits for the diamagnetic Kepler problem

description: In this paper, a method to construct topological template in terms of symbolic dynamics for the diamagnetic Kepler problem is proposed. To confirm the topological template, rotation numbers of invariant manifolds around unstable periodic orbits in a phase space are taken as an object of comparison. The rotation numbers are determined from the definition and connected with symbolic sequences encoding the periodic orbits in a reduced Poincaré section. Only symbolic codes with inverse ordering in the forward mapping can contribute to the rotation of invariant manifolds around the periodic orbits. By using symbolic ordering, the reduced Poincaré section is constricted along stable manifolds and a topological template, which preserves the ordering of forward sequences and can be used to extract the rotation numbers, is established. The rotation numbers computed from the topological template are the same as those computed from their original definition.

Conflicts of Interest between Sharia and International Sale of Goods: Does CISG Interest Fit with Islamic Law?

description: Obligations to pay interest are widely accepted in commerce. However, in Muslim-majority countries subject to sharia law, they are normally forbidden. The United Nations Convention on Contracts for the International Sale of Goods (‘CISG’) art 78 imposes an interest obligation. Consequently, many have been reluctant to accede to the Convention. The CISG Advisory Council has partially addressed how the CISG interest obligation is affected by prohibitions on interest. What remains unresolved is whether this renders the CISG compatible with sharia law. To date, perceptions of their compatibility have relied on generalised views of both the Islamic prohibitions and CISG interest. This article seeks to truly determine whether sharia and the CISG are reconcilable on the question of interest. It examines the basis for Islamic prohibitions on riba and gharar, but importantly, considers differing approaches across individual Muslim-majority states. Likewise, interpretation of the CISG interest obligation is considered in detail. Given this richer contextual landscape, we analyse whether sharia ‘fits’ with the CISG. We conclude that the CISG and sharia are compatible if slight modifications to Opinion No 14 are adopted. This may encourage greater accession to the CISG by Muslim countries as part of their push to adopt laws that attract more international trade
The emergence of dark matter-deficient ultra-diffuse galaxies driven by scatter in the stellar mass-halo mass relation and feedback from globular clusters

description: In addition to their low stellar densities, ultra-diffuse galaxies (UDGs) have a broad variety of dynamical mass-to-light ratios, ranging from dark matter (DM) dominated systems to objects nearly devoid of DM. To investigate the origin of this diversity, we develop a simple, semi-empirical model that predicts the structural evolution of galaxies, driven by feedback from massive star clusters, as a function of their departure from the mean SMHM relation. The model predicts that a galaxy located $\gtrsim 0.5$ dex above the mean relation at $M_{\rm halo}=10^{10}M_{\odot}$ will host a factor of $\sim 10-100$ larger globular cluster (GC) populations, and that feedback from these GCs drives a significant expansion of the stellar component and loss of DM compared to galaxies on the SMHM relation. This effect is stronger in haloes that collapse earlier and have enhanced star formation rates at $z\gtrsim2$, which leads to increased gas pressures, stellar clustering, and mean cluster masses, and significantly enhances the energy loading of galactic winds and its impact on the DM and stellar orbits. The impact on galaxy size and DM content can be large enough to explain observed galaxies that contain nearly the universal baryon fraction, as well as NGC1052-DF2 and DF4 and other isolated UDGs that contain almost no DM. The trend of increasing galaxy size with GC specific frequency observed in galaxy clusters also emerges naturally in the model. Our predictions can be tested with large and deep surveys of the stellar and GC populations in dwarfs and UDGs. Because stellar clustering drives the efficiency of galactic winds, it may be a dominant factor in the structural evolution of galaxies and should be included as an essential ingredient in galaxy formation models.

description: We employ MUSE/VLT data to study the ionised and highly ionised gas phases of the feedback in Circinus, the closest Seyfert 2 galaxy to us. The analysis of the nebular emission allowed us to detect a remarkable high-ionisation gas outflow beyond the galaxy plane traced by the coronal lines [Fe VII] $λ$6089 and [Fe X] $λ$6374, extending up to 700 pc and 350 pc NW from the nucleus, respectively. This is the first time that the [Fe X] emission is observed at such distances from the central engine in an AGN. The gas kinematics reveals expanding gas shells with velocities of a few hundred km s$^{-1}$, spatially coincident with prominent hard X-ray emission detected by Chandra. Density and temperature sensitive line ratios show that the extended high-ionisation gas is characterized by a temperature reaching 25000 K and an electron density > 10$^2$ cm$^{-3}$. We found that local gas excitation by shocks produced by the passage of a radio jet leads to the spectacular high-ionisation emission in this object. This hypothesis is fully supported by photoionisation models that accounts for the combined effects of the central engine and shocks. They reproduce the observed emission line spectrum at different locations inside and outside of the NW ionisation cone. The energetic outflow produced by the radio jet is spatially located close to an extended molecular outflow recently reported using ALMA which suggests that they both represent different phases of the same feedback process acting on the AGN.

description: Gravitomagnetism--a motional coupling of matter analogous to the Lorentz force in electromagnetism--has observable consequences for any scenario involving differing mass currents. Examples include gyroscopes located near a rotating massive body, and the interaction of two orbiting bodies. In the former case, the resulting precession of the gyroscope is often called ``frame dragging,'' and is the principal measurement sought by the Gravity Probe-B experiment. The latter case is realized in the earth-moon system, and the effect has in fact been confirmed via lunar laser ranging (LLR) to approximately 0.1% accuracy--better than the anticipated accuracy of the Gravity-Probe-B result. This paper shows the connnection between these seemingly disparate phenomena by employing the same gravitomagnetic term in the equation of motion to obtain both gyroscopic precession and modification of the lunar orbit. Since lunar ranging currently provides a part in a thousand fit to the gravitomagnetic contributions to the lunar orbit, this feature of post-Newtonian gravity is not adjustable to fit any anomalous result beyond the 0.1% level from Gravity Probe-B without disturbing the existing fit of theory to the 36 years of LLR data.

description: Η δίγλωσση ανάπτυξη και οι επιδόσεις των δίγλωσσων ατόμων στους επιμέρους τομείς της γλώσσας, όπως η φωνολογία, η μορφολογία, η σημασιολογία και η σύνταξη, έχουν κατά καιρούς μονοπωλήσει το ερευνητικό ενδιαφέρον. Σκοπός της παρούσας εργασίας είναι να διερευνηθεί ο βαθμός κατάκτησης του συνοπτικού παρελθοντικού χρόνου, αορίστου, στον τομέα της παραγωγής από δίγλωσσους μαθητές των τάξεων του δημοτικού σχολείου με βάση τα ερευνητικά δεδομένα που αφορούν τους παράγοντες που επηρεάζουν τη δίγλωσση ανάπτυξη. Για τη διεξαγωγή της έρευνας και τη συλλογή δεδομένων χρησιμοποιήθηκε το τεστ αξιολόγησης του συνοπτικού παρελθοντικού χρόνου (αορίστου) «The Perfective Past Tense Test- PPTT» των Stavrakaki και Clahsen (2009). Το δείγμα αποτέλεσαν 10 δίγλωσσοι και τυπικά αναπτυσσόμενοι μαθητές ηλικίας 7 έως 11 ετών. Την ομάδα ελέγχου αποτέλεσαν 12 μονόγλωσσοι και τυπικά αναπτυσσόμενοι μαθητές, επίσης ηλικίας 7 έως 11 ετών. Όλοι αξιολογήθηκαν στον ομαλό και ανώμαλο σχηματισμό του αορίστου υπαρκτών ρημάτων, μη υπαρκτών ρημάτων και ψευδορημάτων. Τα αποτελέσματα έδειξαν ότι ο βαθμός κατάκτησης του χρόνου ποικίλει τόσο μεταξύ των ομάδων μονόγλωσσων και δίγλωσσων μαθητών όσο και μεταξύ των δίγλωσσων μαθητών εντός της ομάδας. Έτσι, παρατηρήθηκε ότι, οι διαφορές αυτές δεν οφείλονται στην ύπαρξη της διγλωσσίας αλλά σε παράγοντες όπως η ηλικία, η σχολική εκπαίδευση, η κυριαρχία και το ποσοστό έκθεσης στην κάθε γλώσσα και οι μορφολογικές ιδιαιτερότητες του χρόνου.
description: The bilingual development and performance of bilingual speakers in specific areas of language, such as phonology, morphology, semantics and syntax have occasionally monopolized the research interest. The aim of this study is to investigate whether bilingual primary school students are capable of using the Perfective Past Tense based on research data, which concern the factors affecting bilingual development. «The Perfective Past Tense Test- PPTT» developed by Stavrakaki and Clahsen (2009) is used for the purposes of this research study and data collection. The sample consisted of 10 bilingual and typically developing primary school students of the age 7 to 11 years. The control group consisted of 12 monolingual and typically developing primary school students of the age 7 to 11 years. All those participants were tested in the regular and irregular formation of Past Tense existing verbs and novel verbs, rhymes and non rhymes. Taking into account the results of this research study, the degree of mastery varies both between monolingual and bilingual groups and between bilingual primary school students within the group. Thus, those differences were not due to the existence of bilingualism but to factors such as age, schooling, language dominance and exposure and morphological features of the tense.
Theory of helimagnons in itinerant quantum systems II: Nonanalytic corrections to Fermi-liquid behavior

description: A recent theory for the ordered phase of helical or chiral magnets such as MnSi is used to calculate observable consequences of the helical Goldstone modes or helimagnons. In systems with no quenched disorder, the helimagnon contributions to the specific heat coefficient is shown to have a linear temperature dependence, while the quasi-particle inelastic scattering rate is anisotropic in momentum space and depends on the electronic dispersion relation. For cubic lattices the generic temperature dependence is given by a non-Fermi-liquid T^(3/2) behavior. The contribution to the temperature dependence of the resistivity is shown to be T^(5/2) in a Boltzmann approximation. The helimagnon thus leads to nonanalytic corrections to Fermi-liquid behavior. Implications for experiments, and for transport theories beyond the Boltzmann level, are discussed.

Equilibrium and non-equilibrium dynamics of the sub-ohmic spin-boson model

description: Employing the non-perturbative numerical renormalization group method, we study the dynamics of the spin-boson model, which describes a two-level system coupled to a bosonic bath with spectral density J(omega) propto omega^s. We show that, in contrast to the case of ohmic damping, the delocalized phase of the sub-ohmic model cannot be characterized by a single energy scale only, due to the presence of a non-trivial quantum phase transition. In the strongly sub-ohmic regime, s<<1, weakly damped coherent oscillations on short time scales are possible even in the localized phase - this is of crucial relevance, e.g., for qubits subject to electromagnetic noise.

Calculated electronic and magnetic properties of the half-metallic, transition metal based Heusler compounds

description: In this work, results of {\it ab-initio} band structure calculations for $A_2BC$ Heusler compounds that have $A$ and $B$ sites occupied by transition metals and $C$ by a main group element are presented. This class of materials includes some interesting half-metallic and ferromagnetic properties. The calculations have been performed in order to understand the properties of the minority band gap and the peculiar magnetic behavior found in these materials. Among the interesting aspects of the electronic structure of the materials are the contributions from both $A$ and $B$ atoms to states near the Fermi energy and to the total magnetic moment. The magnitude of the total magnetic moment, which depends as well on the kind of $C$ atoms, shows a trend consistent with the Slater-Pauling type behavior in several classes of these compounds. The localized moment in these magnetic compounds resides at the $B$ site. Other than in the classical Cu$_2$-based Heusler compounds, the $A$ atoms in Co$_2$, Fe$_2$, and Mn$_2$ based compounds may contribute pronounced to the total magnetic moment.

Neural Transformation Learning for Deep Anomaly Detection Beyond Images

description: Data transformations (e.g. rotations, reflections, and cropping) play an important role in self-supervised learning. Typically, images are transformed into different views, and neural networks trained on tasks involving these views produce useful feature representations for downstream tasks, including anomaly detection. However, for anomaly detection beyond image data, it is often unclear which transformations to use. Here we present a simple end-to-end procedure for anomaly detection with learnable transformations. The key idea is to embed the transformed data into a semantic space such that the transformed data still resemble their untransformed form, while different transformations are easily distinguishable. Extensive experiments on time series demonstrate that our proposed method outperforms existing approaches in the one-vs.-rest setting and is competitive in the more challenging n-vs.-rest anomaly detection task. On tabular datasets from the medical and cyber-security domains, our method learns domain-specific transformations and detects anomalies more accurately than previous work.

description: The first phase of studies of the neutrino mass and mixing is essentially over. The outcome is the discovery of non-zero neutrino mass and determination of the dominant structure of the lepton mixing matrix. In some sense this phase was very simple, and nature was very collaborative with us: Two main effects - the vacuum oscillations and the adiabatic conversion in matter (the MSW-effect) - provide complete interpretation of the experimental results. Furthermore, with the present accuracy of measurements the $3ν-$mixing analysis is essentially reduced to the $2ν$ consideration. I will present a concise and comprehensive description of this first phase. The topics include: (i) the concept of neutrino mixing in vacuum and matter; (ii) physics of the oscillations and adiabatic conversion; (iii) the experimental evidences of the flavor transformations and determination of the oscillation parameters. Some implications of the obtained results are discussed. Comments are given on the next phase of the field that will be much more involved.

Land use and automobile dependence: planning for sustainability in urban regions
Creators: name: Parker, Anthony H.
Publisher: name: University of British Columbia
Year: 2008

description: This thesis investigates how planning for urban land use, form, and design can contribute to reducing society's dependence on automobiles. It provides a synthesis of current literature on this subject and an analysis of this problem within the context of Canadian metropolitan areas. It discusses specific land use and design criteria for reduced automobile dependence, and provides insights into the implementation of these ideas in the Canadian context. The Vancouver metropolitan area provides a focus for this work. The thesis concludes that changing existing land use patterns is essential to achieving long-term reductions in automobile use; that such changes must involve higher densities, greater mixing of land uses, and better design; and that, though there are many strong barriers to change, change can be achieved. It concludes, however, that transforming the auto-oriented built form of Canadian cities will require not only changes to land use and transportation planning, but also institutional change, a changed role for the planning profession, and the mutual education of all the participants in the urban development process.

Discussion on: “Programmable money: next generation blockchain-based conditional payments” by Ingo Weber and Mark Staples

description: My comment on Weber and Staples (Digit Financ, https://doi.org/10.1007/s42521-022-00064-8 [Titel anhand dieser DOI in Citavi-Projekt übernehmen] , 2022) elaborates an economic perspective of their “programmable money” proposal. While claims issued and tendered for goods and services resemble money, a number of issues must be resolved before this innovation is feasible as money in analog trade or digital finance. These include secondary tradability, permissioned access, standardization and transparency. Programmable money is an important step towards the implementation of contingent commodities in the sense of Arrow and Debreu (Econometrica, 22(3):265–290, 1954) and Debreu (1959).
Pair-Density-Wave in the Strong Coupling Limit of the Holstein-Hubbard model

description: A pair-density-wave (PDW) is a novel superconducting state with an oscillating order parameter. A microscopic mechanism that can give rise to it has been long sought but has not yet been established by any controlled calculation. Here we report a density-matrix renormalization group (DMRG) study of an effective $t$-$J$-$V$ model, which is equivalent to the Holstein-Hubbard model in a strong-coupling limit, on long two-, four- and six-leg triangular cylinders. While a state with long-range PDW order is precluded in one dimension, we find strong quasi-long-range PDW order with a divergent PDW susceptibility as well as the spontaneous breaking of time-reversal and inversion symmetries. Despite the strong interactions, the underlying Fermi surfaces and electron pockets around the $K$ and $K^\prime$ points in the Brillouin zone can be identified. We conclude that the state is valley-polarized and that the PDW arises from intra-pocket pairing with an incommensurate center of mass momentum. In the two-leg case, the exponential decay of spin correlations and the measured central charge $c\approx 1$ are consistent with an unusual realization of a Luther-Emery liquid.
