title: Enhanced Covers of Regular and Indeterminate Strings using Prefix Tables

description: A \itbf{cover} of a string $\s{x} = \s{x}[1..n]$
  is a proper substring \s{u} of \s{x} such that
  \s{x} can be constructed from possibly overlapping instances of \s{u}.
  A recent paper \cite{FIKPPST13} relaxes this definition --- an \itbf{enhanced cover} \s{u} of \s{x}
  is a border of \s{x} (that is, a proper prefix that is also a suffix)
  that covers a {\it maximum} number of positions in \s{x}
  (not necessarily all)~--- and
  proposes efficient algorithms for the computation of enhanced covers.
  These algorithms depend on the prior computation of the \itbf{border array} $\s{\beta}[1..n]$,
  where $\s{\beta}[i]$ is the length of the longest border of $\s{x}[1..i]$,
  $1 \le i \le n$.
  In this paper, we first show how to compute enhanced covers using instead the \itbf{prefix table}:
  an array $\s{\pi}[1..n]$ such that~$\s{\pi}[i]$
  is the length of the longest substring of \s{x} beginning at position $i$
  that matches a prefix of \s{x}.
  Unlike the border array, the prefix table is robust: its properties
  hold also for \itbf{indeterminate strings} --- that is,
  strings defined on {\it subsets} of the alphabet~$\Sigma$
  rather than individual elements of $\Sigma$.
  Thus, our algorithms, in addition to being more space-efficient than those of \cite{FIKPPST13},
  allow us to easily extend the computation of enhanced covers
  to indeterminate strings. Both for regular and indeterminate strings,
  our algorithms execute in expected linear time and our experimental results suggest that they are faster than those of \cite{FIKPPST13} in practice.
  Along the way we establish an important theoretical result:
  that the expected maximum length of any border of any prefix of a regular string \s{x}
  is approximately 1.64 for binary alphabets, less for larger ones.

description: We have calculated a series of models of outflows from the obscuring torus in active galactic nuclei (AGN). Our modeling assumes that the inner face of a rotationally supported torus is illuminated and heated by the intense X-rays from the inner accretion disk and black hole. As a result of such heating a strong biconical outflow is observed in our simulations. We calculate 3-dimensional hydrodynamical models, assuming axial symmetry, and including the effects of X-ray heating, ionization, and radiation pressure. We discuss the behavior of a large family of these models, their velocity fields, mass fluxes and temperature, as functions of the torus properties and X-ray flux. Synthetic warm absorber spectra are calculated, assuming pure absorption, for sample models at various inclination angles and observing times. We show that these models have mass fluxes and flow speeds which are comparable to those which have been inferred from observations of Seyfert 1 warm absorbers, and that they can produce rich absorption line spectra.

description: This paper addresses the energy management of a grid-connected photovoltaic plant coupled with a battery energy storage device, within the capacity firming specifications of the French Energy Regulatory Commission. The paper contributions are positioned in the continuity of the studies adopting stochastic models for optimizing the bids of renewable energy sources in a day-ahead market by considering a storage device. The proposed deterministic and stochastic approaches are optimization problems formulated as quadratic problems with linear constraints. The case study is a real microgrid with PV production monitored on-site. The results demonstrate the validity of the stochastic formulation by using an ideal predictor that produces unbiased PV scenarios.

description: Background The objective of this scoping review was to systematically explore the current knowledge of cellular and molecular processes that drive and control trauma-associated root resorption, to identify research gaps and to provide a basis for improved prevention and therapy. Methods Four major bibliographic databases were searched according to the research question up to February 2021 and supplemented manually. Reports on physiologic, histologic, anatomic and clinical aspects of root resorption following dental trauma were included. Duplicates were removed, the collected material was screened by title/abstract and assessed for eligibility based on the full text. Relevant aspects were extracted, organized and summarized. Results 846 papers were identified as relevant for a qualitative summary. Consideration of pathophysiological mechanisms concerning trauma-related root resorption in the literature is sparse. Whereas some forms of resorption have been explored thoroughly, the etiology of others, particularly invasive cervical resorption, is still under debate, resulting in inadequate diagnostics and heterogeneous clinical recommendations. Effective therapies for progressive replacement resorptions have not been established. Whereas the discovery of the RANKL/RANK/OPG system is essential to our understanding of resorptive processes, many questions regarding the functional regulation of osteo-/odontoclasts remain unanswered. Conclusions This scoping review provides an overview of existing evidence, but also identifies knowledge gaps that need to be addressed by continued laboratory and clinical research.

The third wave of Indonesia’s food market: Practices at small community markets in Yogyakarta
Creators: name: Widiyanto, Dodi
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2019

description: There is growing awareness among people living in developing countries of the importance of healthy lifestyles. Farmers’ markets (FMs) are a rather new type of market in Indonesia, succeeding traditional and modern markets. They began to appear in 2006 in Bali and were established in Yogyakarta in the early 2010s. This article contributes to limited research in this area by presenting a qualitative analysis of market participants with three main aims: to explore the meanings of local and healthy food from the vendors’/managers’ perspective, to identify the vendors’/managers’ motives for using FMs, and to examine the mechanisms underpinning the performance of FMs. I found no consensus regarding the meanings of local and healthy food. Instead, market participants have a geographically wide concept of ‘local’ that includes perceived high-quality (and healthy) raw materials from all over the Indonesian Archipelago. To assure the quality of food from such distant sources, formal and informal market mechanisms are used in Greater Yogyakarta FMs, as evidenced by the unique practices designed by the markets’ vendors and managers.

Spectral inversion of an indefinite Sturm-Liouville problem due to Richardson

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We study an indefinite Sturm-Liouville problem due to Richardson whose complicated eigenvalue dependence on a parameter has been a puzzle for decades. In atomic physics a process exists that inverts the usual Schrodinger situation of an energy eigenvalue depending on a coupling parameter into the so-called Sturmian problem where the coupling parameter becomes the eigenvalue which then depends on the energy. We observe that the Richardson equation is of the Sturmian type. This means that the Richardson and its related Schrodinger eigevalue functions are inverses of each other and that the Richardson spectrum is therefore no longer a puzzle.

description: Non-Maximum Suppression (NMS) is essential for object detection and affects the evaluation results by incorporating False Positives (FP) and False Negatives (FN), especially in crowd occlusion scenes. In this paper, we raise the problem of weak connection between the training targets and the evaluation metrics caused by NMS and propose a novel NMS-Loss making the NMS procedure can be trained end-to-end without any additional network parameters. Our NMS-Loss punishes two cases when FP is not suppressed and FN is wrongly eliminated by NMS. Specifically, we propose a pull loss to pull predictions with the same target close to each other, and a push loss to push predictions with different targets away from each other. Experimental results show that with the help of NMS-Loss, our detector, namely NMS-Ped, achieves impressive results with Miss Rate of 5.92% on Caltech dataset and 10.08% on CityPersons dataset, which are both better than state-of-the-art competitors.

description: Scattering thresholds and their associated spectral square root branch points are ubiquitous in photonics. In this Letter, we show that the scattering matrix has a simple universal behavior near scattering thresholds. We use unitarity, reciprocity, and time-reversal symmetry to construct a two-parameter model for a two-port scattering matrix near a threshold. We demonstrate this universal behavior in three different optical systems, namely a photonic crystal slab, a planar dielectric interface, and a junction between metallic waveguides of different widths.

description: We report the synthesis and physical properties of a full Heusler compound, MgPd$_2$Sb, which we found to show superconductivity below $T_c$ = 2.2 K. MgPd$_2$Sb was obtained by a two-step solid-state reaction method and its purity and cubic crystal structure (Fm-3m, a=6.4523(1) Å) were confirmed by powder x-ray diffraction. Normal and superconducting states were studied by electrical resistivity, magnetic susceptibility, and heat capacity measurements. The results show that MgPd$_2$Sb is a type-II, weak coupling superconductor ($λ_{e-p}$ = 0.53). The observed pressure dependence of $T_c$ ($ΔT_c / p \approx $ -0.23 K/GPa) is one of the strongest reported for a superconducting Heusler compound. The electronic structure, phonons, and electron-phonon coupling in MgPd$_2$Sb were theoretically investigated. The obtained results are in agreement with the experiment, confirming the electron-phonon coupling mechanism of superconductivity. We compare the superconducting parameters tothose of all reported Heusler-type superconductors.

description: We show that the N=8 superconformal Bagger-Lambert theory based on the Lorentzian 3-algebra can be derived by taking a certain scaling limit of the recently proposed N=6 superconformal U(N)xU(N) Chern-Simons-matter theories at level (k, -k). The scaling limit (and Inonu-Wigner contraction) is to scale the trace part of the bifundamental fields as X_0 -> λ^{-1} X_0 and an axial combination of the two gauge fields as B_μ -> λB_μ. Simultaneously we scale the level as k -> λ^{-1} k and then take λ-> 0 limit. Interestingly the same constraint equation \partial^2 X_0=0 is derived by imposing finiteness of the action. In this scaling limit, M2-branes are located far from the origin of C^4/Z_k compared to their fluctuations and Z_k identification becomes a circle identification. Hence the scaled theory describes N=8 supersymmetric theory of 2-branes with dynamical coupling. The coupling constant is promoted to a space-time dependent SO(8) vector X_0^I and we show that the scaled theory has a generalized conformal symmetry as well as manifest SO(8) with the transformation of the background fields X_0^I.

description: Forschungsvorhaben im Ingenieurbereich sind häufig Verbundprojekte, wie das hier vorgestellte AMTwin. Das Verbundvorhaben AMTwin entwickelt Modelle für die Abbildung von Wechselwirkungen zwischen Material- und Fertigungsprozessparametern und finalen Bauteileigenschaften. Die Bauteile aus Ti6Al4V werden mittels Selektivem Laserschmelzen hergestellt. Die Modellbildung erfolgt auf Mikrostrukturebene und ist auf Daten aus dem Fertigungsprozess und der Werkstoff- und Struktur-prüfung gestützt. Die nachvollziehbare Dokumentation und Verknüpfung der Daten entlang der Prozesskette sind dabei zwei zentrale Herausforderungen für eine erfolgreiche Bearbeitung des Verbundprojekts. Aus der kollaborativen Arbeit resultieren weitere charakteristische Herausforderungen. Um diese Herausforderungen zu effizient bewältigen zu können, ist ein funktionierendes Forschungsdatenmanagement (FDM) zwingend notwendig. Somit ist das FDM mehr als Service als eine zu erfüllende Bedingung der Projektträger zu verstehen. In dieser Arbeit wird ein Konzept für ein praktikables FDM vorgestellt, das den gesamten Forschungsdatenlebenszyklus berücksichtigt. Im Konzept werden die Prozessdaten über Metadaten dokumentiert, deren Metadatenschemata auf einer Ontologie zur Additiven Fertigung basieren. Die Ontologie bildet dabei die Grundlage für eine einheitliche, gemeinsame Fachsprache über Labor- und Projektgrenzen hinweg. Die Idee ist, den Datenfluss bis zum „Open Access Repository and Archive“ zu führen, welches an die Metadaten anknüpft. Gezeigt wird der in Kooperation mit der Beratungsstelle Forschungsdatenmanagement umgesetzte Ansatz auf Basis von Microsoft Sharepoint, der als Möglichkeit der schnellen und einfachen Verbreitung gesehen wird.
China’s cultural diplomacy in Malaysia during Najib Razak’s premiership

description: This article aims to provide an analysis of China’s cultural diplomacy (CCD) in Malaysia in the latter years of the premiership of Najib Razak (2015-2018). It intends to reflect on the efforts China has been exerting in order to increase its soft power in the Southeast Asian nation. The authors have identified and analyzed four major fields of CCD: the activities of two Confucius Institutes; the first overseas campus of a renowned Chinese university; invocations of shared history, embodied mainly by the figure of the legendary admiral-eunuch Zheng He, regularly commemorated as China’s historic envoy of peace; and Malay translations of classical Chinese novels. The article’s findings reveal an intricate pattern of networks involving various actors, both Chinese and Malaysian, state, semi-state, and non-state, pursuing their own particular interests, which tend to converge and overlap with the aims of Chinese cultural diplomacy. The implementation of CCD has also been formed by the local political and societal structures: a) a ‘special’ relation between Razak’s cabinet and the PRC leadership, revolving around party-based diplomacy and intensive economic cooperation especially between 2015 and May 2018; b) the presence of a large Chinese community, which provides opportunities and, at the same time, creates limitations for the China´s cultural diplomacy practice in Malaysia.

description: Interference between two completely independent photons lies at the heart of many photonic quantum information applications such as quantum repeaters, teleportation, and quantum key distribution. Here, we report the observation of Hong-Ou-Mandel (HOM) interference with two independent continuous-wave coherent light sources that are neither synchronized nor share any common reference. To prepare highly indistinguishable photons from two independent laser sources, we employ high-precision frequency-stabilization techniques using the 5S1/2(F=3)-5P1/2(F'=3) transition line of 85Rb atoms. We successfully observe a HOM interference fringe with two independent continuous-wave coherent photons originating from either the frequency-locked and frequency-modulated lasers. An interference fringe involving two-photon beating is also observed when the frequency difference between the two interfering photons is beyond the spectral bandwidth of the individual coherent photons. We carry out further experiments to verify the robustness of the source preparation regardless of the separation distance between the two independent photon sources.

description: We report total abundances and related parameters for the full sample of the FUSE survey of molecular hydrogen in 38 translucent lines of sight. New results are presented for the "second half" of the survey involving 15 lines of sight to supplement data for the first 23 lines of sight already published. We assess the correlations between molecular hydrogen and various extinction parameters in the full sample, which covers a broader range of conditions than the initial sample. In particular, we are now able to confirm that many, but not all, lines of sight with shallow far-UV extinction curves and large values of the total-to-selective extinction ratio, $R_V$ = $A_V$ / $E(B-V)$ -- characteristic of larger than average dust grains -- are associated with particularly low hydrogen molecular fractions ($f_{\rm H2}$). In the lines of sight with large $R_V$, there is in fact a wide range in molecular fractions, despite the expectation that the larger grains should lead to less H$_2$ formation. However, we see specific evidence that the molecular fractions in this sub-sample are inversely related to the estimated strength of the UV radiation field and thus the latter factor is more important in this regime. We have provided an update to previous values of the gas-to-dust ratio, $N$(H$_{\rm tot}$)/$E(B-V)$, based on direct measurements of $N$(H$_2$) and $N$(H I). Although our value is nearly identical to that found with Copernicus data, it extends the relationship by a factor of 2 in reddening. Finally, as the new lines of sight generally show low to moderate molecular fractions, we still find little evidence for single monolithic "translucent clouds" with $f_{\rm H2}$ $\sim$ 1.

description: Recent discovery of spin-orbit torques (SOTs) within magnetic single-layers has attracted attention in the field of spintronics. However, it has remained elusive as to how to understand and how to tune the SOTs. Here, utilizing the single layers of chemically disordered Fe$_x$Pt$_{1-x}$, we unveil the mechanism of the "unexpected" bulk SOTs by studying their dependence on the introduction of a controlled vertical composition gradient and on temperature. We find that the bulk damping like SOT arises from an imbalanced internal spin current that is transversely polarized and independent of the magnetization orientation. The torque can be strong only in the presence of a vertical composition gradient and the SOT efficiency per electric field is insensitive to temperature but changes sign upon reversal of the orientation of the composition gradient, which are in analogue to behaviors of the strain. From these characteristics we conclude that the imbalanced internal spin current originates from a bulk spin Hall effect and that the associated inversion asymmetry that allows for a non-zero net torque is most likely a strain non-uniformity induced by the composition gradient. The fieldlike SOT is a relatively small bulk effect compared to the dampinglike SOT. This work points to the possibility of developing low-power single-layer SOT devices by strain engineering.

description: By cyclic adiabatic change of two control parameters of an optical trap one can induce a circulating current of condensed bosons. The amount of particles that are transported per period depends on the "radius" of the cycle, and this dependence can be utilized in order to probe the interatomic interactions. For strong repulsive interaction the current can be regarded as arising from a sequence of Landau-Zener crossings. For weaker interaction one observes either gradual or coherent mega crossings, while for attractive interaction the particles are glued together and behave like a classical ball. For the analysis we use the Kubo approach to quantum pumping with the associated Dirac monopoles picture of parameter space.

description: Extracellular recordings are severely contaminated by a considerable amount of noise sources, rendering the denoising process an extremely challenging task that should be tackled for efficient spike sorting. To this end, we propose an end-to-end deep learning approach to the problem, utilizing a Fully Convolutional Denoising Autoencoder, which learns to produce a clean neuronal activity signal from a noisy multichannel input. The experimental results on simulated data show that our proposed method can improve significantly the quality of noise-corrupted neural signals, outperforming widely-used wavelet denoising techniques.

description: Die Diplomarbeit beschäftigt sich mit der Beziehung des Einen zum Anderen bei E. Levinas und V. Havel. Im Zentrum der Untersuchung steht die unendliche Verantwortung für den und die Anderen. Der Ausgangspunkt, ist die ethische Beziehung, die auf einer vor-philosophischen Erfahrung gründet. Sie ist gleichzeitig der (Un-)Ort, an dem die Menschlichkeit erfahren wird. Der Andere ist immer schon der Dritte, d. h. viele Andere, er stört und fordert Gerechtigkeit.
Basierend darauf, wird der Verantwortungsdiskurs bei Levinas und Havel in Bezug zueinander gestellt und auf Übereinstimmungen überprüft.

"Who cares?" Das österreichische und deutsche Pflegesystem im Falle eines Pflegefalles
Creators: name: Feigl, Katharina
Year: 2012

description: Due to a demographic shift, and an aging demographic profile, the population comprises a higher percentage of old people in relation to young people. The resultant of this fact is that in the future there will be a higher demand in the area of health care for the aged. The objective of this paper is to give an insight into the health care of the aged systems in Austria and Germany, and to highlight the differences in the systems. The major difference is that a mandatory health care for the nursing care insurance exists in Germany. In Austria health care is divided into seven areas, while in Germany it is only divided into three areas. In Austria the assessment of level of care required may be conducted by a general practitioner, while in Germany this evaluation is conducted by highly qualified health care professionals. The term "dependent on care" is legally recognised in Germany. Positive elements of the Austrian system are; the seven levels care system as well as the substantial amount of care support funds. Positive elements of the German system are; the legal definition of the term "dependent on care", and qualified health care professionals evaluating the level of care required. Further more Austria requires the legal recognition of the term "dependent on care", as well as a reliable and valid evaluation assessment test for identifying the level of care required by a patient.
description: Durch den demographischen Wandel leben immer mehr ältere Menschen und immer weniger junge unter uns. Ein Fakt daraus ist, dass auch die Pflegebedürftigkeit in Zukunft stetig ansteigen wird. Die Ziele dieser Arbeit sind, einen Einblick in die Pflegesysteme Österreichs und Deutschlands zu bekommen und Unterschiede der Systeme aufzuzeigen. Die größte Differenz ist, dass in Deutschland eine obligatorische Pflegeversicherung existiert. In Österreich wird das Pflegegeld in sieben Stufen, in Deutschland in drei Stufen unterteilt. Ist in Österreich die Pflegebegutachtung nur durch einen Arzt erlaubt, so geschieht dies in Deutschland durch Pflegefachpersonal des gehobenen Dienstes. In Deutschland steht der Begriff der Pflegebedürftigkeit gesetzlich fest. Für Österreich sprechen das siebenstufige Pflegesystem und die Höhe des Pflegegeldes. Aus Deutschland kann die gesetzliche Definition des Begriffes der Pflegebedürftigkeit und die Begutachtung durch Pflegepersonal positiviert werden. Österreich benötigt weiters einen Pflegebedürftigkeitsbegriff, sowie ein auf Reliabilität und Validität geprüftes Begutachtungsinstrument zur Feststellung der Pflegebedürftigkeit.
title: The idea of the sacred in neoclassical British gardens of the eighteenth and late twentieth centuries
Creators: name: Charlesworth, Michael
Publisher: name: University of Kent
Year: 1990

description: This study takes as its subject the sacred element in neo-classical gardens of the 18th and late 20th centuries. This element may be represented in the classical idiom (by temples or statues), or translated into the terms of the Christian religion as practised in England. The study argues that sacred ideas are an important motivating force in garden design, and moreover have a prominent socio-political content. It demonstrates this force at work by focussing first on the devotional aspects of Alexander Pope's garden, which, it is argued, displays an ecclesiastical ichnography informed by Roman Catholic values. In the middle of the 18th century, by contrast, political and cultural hostility to Roman Catholicism finds expression in the design of the landscape garden. During the second half of the century the constitutionally assured supremacy of the Church of England is also reflected in landscape garden design. Duncombe Park with Rievaulx Terrace, and Sledmere House, provide examples of these changes. Sacred neo-classical gardening emerges from 19th century eclipse to find its fullest contemporary expression in the work of Ian Hamilton Finlay, whose garden in Scotland is tested here for consistency to the 18th century tradition he often invokes. His work also provides the material for a modern definition of the sacred idea. While it is still connected to political ideas, the sacred is now divorced from involvement with the Christian Churches and allied to imaginative and poetic effects of gardens and landscape. Throughout the study evidence from literature, painting and architectural history is brought to bear on the subject, and it is argued that the connection between signs of the sacred in the garden and actual sacred practices in society is essentially a rhetorical one.

description: The number density of galaxy clusters provides tight statistical constraints on the matter fluctuation power spectrum normalization, traditionally phrased in terms of sigma_8, the root mean square mass fluctuation in spheres with radius 8 h^-1 Mpc. We present constraints on sigma_8 and the total matter density Omega_m0 from local cluster counts as a function of X-ray temperature, taking care to incorporate and minimize systematic errors that plagued previous work with this method. In particular, we present new determinations of the cluster luminosity - temperature and mass - temperature relations, including their intrinsic scatter, and a determination of the Jenkins mass function parameters for the same mass definition as the mass - temperature calibration. Marginalizing over the 12 uninteresting parameters associated with this method, we find that the local cluster temperature function implies sigma_8 (Omega_m0/0.32)^alpha = 0.86+/-0.04 with alpha = 0.30 (0.41) for Omega_m0 < 0.32 (Omega_mo > 0.32) (68% confidence for two parameters). This result agrees with a wide range of recent independent determinations, and we find no evidence of any additional sources of systematic error for the X-ray cluster temperature function determination of the matter power spectrum normalization. The joint WMAP5 + cluster constraints are: Omega_m0 = 0.30+0.03/-0.02 and sigma_8 = 0.85+0.04/-0.02 (68% confidence for two parameters).

Given changes in how people are using electricity, is an AC-only electrical system still the right option for a residence of the future? Conversion losses already are growing with wide use of consumer electronics, and they will get bigger still as photovoltaic and car-charging systems evolve. This is why experts are starting to seriously consider the prospect of hybrid AC/DC residential electrical systems.
