description: The dissociation of molecules, even the most simple hydrogen molecule, cannot be described accurately within density functional theory because none of the currently available functionals accounts for strong on-site correlation. This problem has led to a discussion of properties that the local Kohn-Sham potential has to satisfy in order to correctly describe strongly correlated systems. We derive an analytic expression for this potential at the dissociation limit and show that the numerical calculations for a one-dimensional two electron model system indeed approach and reach this limit. It is shown that the functional form of the potential is universal, i.e. independent of the details of the system.

description: We study the non-trivial phase of the two-dimensional breathing kagome lattice, displaying both edge and corner modes. The corner localized modes of a two-dimensional flake were initially identified as a signature of a higher-order topological phase but later shown to be trivial for perturbations that were thought to protect them. Using various theoretical and simulation techniques, we confirm that it does not display higher-order topology: the corner modes are of trivial nature. Nevertheless, they might be protected. First, we show a set of perturbations within a tight-binding model that can move the corner modes away from zero energy, also repeat some perturbations that were used to show that the modes are trivial. In addition, we analyze the protection of the corner modes in more detail and find that only perturbations respecting the sublattice or generalized chiral and crystalline symmetries, and the lattice connectivity, pin the corner modes to zero energy robustly. A destructive interference model corroborates the results. Finally, we analyze a muffin-tin model for the bulk breathing kagome lattice. Using topological and symmetry markers, such as Wilson loops and Topological Quantum Chemistry, we identify the two breathing phases as adiabatically disconnected different obstructed atomic limits.

Did the Universe Experienced a Pressure non-Crushing Type Cosmological Singularity in the Recent Past?

description: In the recent literature it has been shown that the $H_0$ tension may be eliminated if an abrupt physics transition changed the Cepheid parameters in the near past of the Universe, nearly $70-150\,$Myrs ago. In this letter we stress the possibility that this abrupt transition was caused by the smooth passage of our Universe through a pressure finite-time cosmological singularity. Being a non-crushing type singularity the pressure singularity can leave its imprints in the Universe, since it occurs globally and literally everywhere. We discuss how this scenario could easily be realized by $F(R)$ gravity, with the strong energy conditions being satisfied without the need for a scalar field or specific matter fluids. We also stress the fact that the pressure singularity can affect the effective gravitational constant of $F(R)$ gravity. Moreover, we stress the fact that pressure singularities can disrupt the trajectories of bound objects in the Universe, which is also pointed out in the literature, even in the context of general relativity. We also show numerically in a general relativistic framework that elliptic trajectories are distorted and changed to different elliptic trajectories when the Universe passes through the pressure singularity. Such a disruption of the trajectories could have tidal effects on the surface of the earth, for example on sea waters and oceans, regarding the distortion of moon's elliptic trajectory. Accordingly, the distortion of earth's trajectory around the sun could have affected climatologically earth $70-150\,$Myrs ago.

description: The need for purely laboratory-based light pseudoscalar particles searches has been emphasized many times in the literature, since astrophysical bounds on these particles rely on several assumptions to calculate the flux produced in stellar plasmas. In this paper we study the use of light from synchrotron accelerators as a source for a photon regeneration experiment also know as "light shining through a wall". Such an experiment can significantly improve present limits on the pseudoscalar particle mass and the pseudoscalar-photon coupling constant obtained from laser experiments. This is possible even using a small number of powerful magnets (B = 10 T), due to the large incident photon flux. On the other hand, the use of a broadband incident photon-beam instead of infrared or optical lasers allows a significant improvement in the mass reach of the experiment (it is possible to test masses up to 0.01 eV without a drop in sensitivity). Large, but still feasible, configurations can explore in a quite model-independent way a large part of the parameter space examined by solar searches and HB stars in globular clusters. Additionally, the proposal may be useful for testing string motivated effective theories containing light and weakly interacting particles.

The Delineation of an Interdisciplinary Specialty in terms of a Journal Set: The Case of Communication Studies

description: A journal set in an interdisciplinary or newly developing area can be determined by including the journals classified under the most relevant ISI Subject Categories into a journal-journal citation matrix. Despite the fuzzy character of borders, factor analysis of the citation patterns enables us to delineate the specific set by discarding the noise. This methodology is illustrated using communication studies as a hybrid development between political science and social psychology. The development can be visualized using animations which support the claim that a specific journal set in communication studies is increasingly developing, notably in the "being cited" patterns. The resulting set of 28 journals in communication studies is smaller and more focused than the 45 journals classified by the ISI Subject Categories as "Communication". The proposed method is tested for its robustness by extending the relevant environments to sets including many more journals.

description: We present a new experimental method to generate quasi-perpendicular supercritical magnetized collisionless shocks. In our experiment, ambient nitrogen (N) plasma is at rest and well-magnetized, and it has uniform mass density. The plasma is pushed by laser-driven ablation aluminum (Al) plasma. Streaked optical pyrometry and spatially resolved laser collective Thomson scattering clarify structures of plasma density and temperatures, which are compared with one-dimensional particle-in-cell simulations. It is indicated that just after the laser irradiation, the Al plasma is magnetized by a self-generated Biermann battery field, and the plasma slaps the incident N plasma. The compressed external field in the N plasma reflects N ions, leading to counter-streaming magnetized N flows. Namely we identify the edge of the reflected N ions. Such interacting plasmas form a magnetized collisionless shock.

description: We consider the nonparametric functional estimation of the drift of a Gaussian process via minimax and Bayes estimators. In this context, we construct superefficient estimators of Stein type for such drifts using the Malliavin integration by parts formula and superharmonic functionals on Gaussian space. Our results are illustrated by numerical simulations and extend the construction of James--Stein type estimators for Gaussian processes by Berger and Wolpert [J.

The inter-relationship of music and English poetry during the Middle Ages (1150-1500)
Creators: name: Badger, Sophie A. F.
Publisher: name: University of British Columbia
Year: 2012

description: This thesis must be regarded as an outline, rather than an exhaustive study, of the inter-relationship of music and poetry during the Middle Ages (that is, from the middle of the twelfth to the end of the fifteenth century). It is always difficult to set limits for creative movements and, when they have been set, to justify them and to work consistently within them, for one cannot make definite divisions between movements, nor confine trends of thought and creative impulse within the boundaries of a definite space of time. The year 1150 was chosen as the first limit of this essay because little in English has come down to us from the first half of the century, and the small amount that has, belongs to the Old English rather than the Middle English tradition. Since medieval and renaissance trends overlapped each other throughout the entire fifteenth century the terminal limit (1500) had to be chosen arbitrarily. The adoption of 1500 has more than the convenience of a round number to recommend it, however, for most of the literature of the fifteenth century belongs to the Middle English tradition; even those developments at the end of the century which look forward to the renaissance are not of such a revolutionary character that they cannot he considered as still part of medieval literature. While music shows some analogies with all its sister arts, it is the art of poetry that it resembles most. The present work, therefore, deals primarily with the characteristics of the form and style of medieval music (special emphasis being given to the music of the church) and its influence on poetic forms like the lyric and liturgical drama. The main contention of the thesis is that, during the monodic period of music, the two arts were completely dependent on one another. With the development of polyphony, however, music became so intricate that it could no longer be used as a vehicle for words. The old union of poetry and music was gone, never to return in quite the same way again. Although it is true that music and poetry came together for a brief period in the Elizabethan Age it was not the same kind of unity. In the renaissance, music and poetry were two mature arts that enhanced one another; either one could be enjoyed without the other, but, in the Middle Ages, (that is, the period in which monodic music flourished) neither the music nor the poetry was complete in itself — they were created for one another.

Tidal disruption events in post-starburst galaxies: the importance of a complete stellar mass function

description: A tidal disruption event (TDE) occurs when a star is destroyed by the strong tidal shear of a massive black hole (MBH). The accumulation of TDE observations over the last years has revealed that post-starburst galaxies are significantly overrepresented in the sample of TDE hosts. Here we address the post-starburst preference by investigating the decline of TDE rates in a Milky-Way like nuclear stellar cluster featuring either a monochromatic (1 M$\odot$) or a complete, evolved stellar mass function. In the former case, the decline of TDE rates with time is very mild, and generally up to a factor of a few in 10 Gyr. Conversely, if a complete mass function is considered, a strong TDE burst over the first 0.1-1 Gyr is followed by a considerable rate drop, by at least an order of magnitude over 10 Gyr. The decline starts after a mass segregation time-scale, and it is more pronounced assuming a more top-heavy initial mass function and/or an initially denser nucleus. Our results thus suggest that the post-starburst preference can be accounted for in realistic systems featuring a complete stellar mass function, even in moderately dense galactic nuclei. Overall, our findings support the idea that starbursting galactic nuclei are characterized by a top-heavy initial mass function; we speculate that accounting for this can reconcile the discrepancy between observed and theoretically predicted TDE rates even in quiescent galaxies.

description: We present the results of an XMM-Newton mosaic covering the central ~200 kpc of the nearby Virgo cluster. We focus on a strong surface brightness discontinuity in the outskirts of the brightest cluster galaxy, M87. Using both XMM-Newton and Suzaku, we derive accurate temperature and metallicity profiles across this feature and show that it is a cold front probably due to sloshing of the Virgo ICM. It is also associated with a discontinuity in the chemical composition. The gas in the inner, bright region of the front is ~40% more abundant in Fe than the gas outside the front, suggesting the important role of sloshing in transporting metals through the ICM. For the first time, we provide a quantitative estimate of the mass of Fe transported by a cold front. This amounts to ~6% of the total Fe mass within the radial range affected by sloshing, significantly more than the amount of metals transported by the AGN in the same cluster core. The very low Fe abundance of only ~0.2 solar immediately outside the cold front at a radius of 90 kpc suggests we are witnessing first-hand the transport of higher metallicity gas into a pristine region, whose abundance is typical of the cluster outskirts. The Mg/Fe and O/Fe abundance ratios remain approximately constant over the entire radial range between the centre of M87 and the faint side of the cold front, which requires the presence of a centrally peaked distribution not only for Fe but also for core-collapse type supernova products. This peak may stem from the star formation triggered as the BCG assembled during the protocluster phase.

description: In this paper, we obtain some new explicit travelling wave solutions of the perturbed KdV equation through recent factorization techniques that can be performed when the coefficients of the equation fulfill a certain condition. The solutions are obtained by using a two-step factorization procedure through which the perturbed KdV equation is reduced to a nonlinear second order differential equation, and to some Bernoulli and Abel type differential equations whose solutions are expressed in terms of the exponential and Weierstrass functions

L'incidenza dell'ambiente spaziale, della microgravità, sul fisico di pur ben addestrati astronauti è rilevante dopo una lunga permanenza fuori dalla Terra. Alcuni degli effetti sono osteoporosi, nausea spaziale, perdita di massa ossea e muscolare, problemi cardiaci e perdita di cognizione visiva. Insomma se sulla Terra sembra facile scavalcare un ostacolo camminando, farlo dopo una lunga permanenza è tutto un altro problema
How does unlabeled data improve generalization in self-training? A one-hidden-layer theoretical analysis

description: Self-training, a semi-supervised learning algorithm, leverages a large amount of unlabeled data to improve learning when the labeled data are limited. Despite empirical successes, its theoretical characterization remains elusive. To the best of our knowledge, this work establishes the first theoretical analysis for the known iterative self-training paradigm and proves the benefits of unlabeled data in both training convergence and generalization ability. To make our theoretical analysis feasible, we focus on the case of one-hidden-layer neural networks. However, theoretical understanding of iterative self-training is non-trivial even for a shallow neural network. One of the key challenges is that existing neural network landscape analysis built upon supervised learning no longer holds in the (semi-supervised) self-training paradigm. We address this challenge and prove that iterative self-training converges linearly with both convergence rate and generalization accuracy improved in the order of $1/\sqrt{M}$, where $M$ is the number of unlabeled samples. Experiments from shallow neural networks to deep neural networks are also provided to justify the correctness of our established theoretical insights on self-training.

description: High-resolution hard X-ray photoemission measurements have been performed to clarify the electronic structure originating from the strong correlation between electrons in bulk Ce 3$d$ core-level spectra of CeNi$_{1-x}$Co$_x$Ge$_2$ (0 $\leq$ $x$ $\leq$ 1). In the Ce 3$d_{5/2}$ core-level spectra, the variation of satellite structures ($f^2$ peaks) shows that the hybridization strength between Ce 4$f$- and conduction electrons gradually increases with Co concentration in good agreement with the results of Ce 3$d-4f$ and 4$d-4f$ resonant photoemission spectroscopies. Particularly, in Ce 3$d_{3/2}$ core-level spectra, the multiplet structures of $f^1$ peaks systematically change with the degeneracy of $f$-states which originates from crystalline electric field effects.

Sum Rates, Rate Allocation, and User Scheduling for Multi-User MIMO Vector Perturbation Precoding

description: This paper considers the multiuser multiple-input multiple-output (MIMO) broadcast channel. We consider the case where the multiple transmit antennas are used to deliver independent data streams to multiple users via vector perturbation. We derive expressions for the sum rate in terms of the average energy of the precoded vector, and use this to derive a high signal-to-noise ratio (SNR) closed-form upper bound, which we show to be tight via simulation. We also propose a modification to vector perturbation where different rates can be allocated to different users. We conclude that for vector perturbation precoding most of the sum rate gains can be achieved by reducing the rate allocation problem to the user selection problem. We then propose a low-complexity user selection algorithm that attempts to maximize the high-SNR sum rate upper bound. Simulations show that the algorithm outperforms other user selection algorithms of similar complexity.

description: Deep-sea environments, in contrast to coastal ecosystems, are generally less adaptive to environmental changes and its species and habitats are therefore more sensitive to climate change impacts.

The ocean has absorbed most of the additiona lheat and about a quarter of the additional atmospheric carbon dioxide from human activities. Even though this has helped keep the planet cooler than it would otherwise be, this has also caused deep-sea ecosystems to increase in temperature and acidity, lose oxygen, and have less food available. 

These changes to deep-sea ecosystems will:

reduce the capacity of deep-sea sediments to store carbon and recycle nutrients;

impact coral reef structure and complexity, reducing associated biodiversity and functions;

impact deep-sea sponges risking, for example, a loss of natural pharmaceuticals; and

impact fishing activities.

By taking decisive action to address climate change, strengthen existing protections, and fill critical knowledge gaps, Scotland can ensure the long-term health and resilience of its unique and valuable deep-sea ecosystems The following actions are recommended:

1. Assess the resilience of the existing Marine Protected Area (MPA) network to climate change. Identify climate change refugia and predict shifts in ecological connectivity, informing adaptive management strategies and the development of strategic approaches to ensure MPAs effectively protect deep-sea features under current and future conditions.

2. Reduce existing human pressures to support resilience and recovery. This will increase the opportunities for resilience of species and habitats to the impacts of climate change, improving their ability to adapt and survive. This protects the many benefits that Scottish people receive from the deep sea.

3. Address knowledge gaps. Impacts of climate-induced environmental change at species, habitat and ecosystem level, that are in addition to the impacts of fishing and pollutants, require continued investigation. This should include pelagic ecosystems, vulnerable and important species (e.g. sponges, corals, fish), deep-sea sediments and the carbon sink.

4. Strongly advocate for global reductions in greenhouse gas emissions.
