description: In comparative genomics, the rearrangement distance between two genomes (equal the minimal number of genome rearrangements required to transform them into a single genome) is often used for measuring their evolutionary remoteness. Generalization of this measure to three genomes is known as the median score (while a resulting genome is called median genome). In contrast to the rearrangement distance between two genomes which can be computed in linear time, computing the median score for three genomes is NP-hard. This inspires a quest for simpler and faster approximations for the median score, the most natural of which appears to be the halved sum of pairwise distances which in fact represents a lower bound for the median score. In this work, we study relationship and interplay of pairwise distances between three genomes and their median score under the model of Double-Cut-and-Join (DCJ) rearrangements. Most remarkably we show that while a rearrangement may change the sum of pairwise distances by at most 2 (and thus change the lower bound by at most 1), even the most "powerful" rearrangements in this respect that increase the lower bound by 1 (by moving one genome farther away from each of the other two genomes), which we call strong, do not necessarily affect the median score. This observation implies that the two measures are not as well-correlated as one's intuition may suggest. We further prove that the median score attains the lower bound exactly on the triples of genomes that can be obtained from a single genome with strong rearrangements. While the sum of pairwise distances with the factor 2/3 represents an upper bound for the median score, its tightness remains unclear. Nonetheless, we show that the difference of the median score and its lower bound is not bounded by a constant.

title: Low Flow and Drought in a German Low Mountain Range Basin

description: Rising temperatures and changes in precipitation patterns in the last decades have led to an increased awareness on low flow and droughts even in temperate climate zones. The scientific community often considers low flow as a consequence of drought. However, when observing low flow, catchment processes play an important role alongside precipitation shortages. Therefore, it is crucial to not neglect the role of catchment characteristics. This paper seeks to investigate low flow and drought in an integrative catchment approach by observing the historical development of low flows and drought in a typical German low mountain range basin in the federal state of Hesse for the period 1980 to 2018. A trend analysis of drought and low flow indices was conducted and the results were analyzed with respect to the characteristics of the Gersprenz catchment and its subbasin, the Fischbach. It was shown that catchments comprising characteristics that are likely to evoke low flow are probably more likely to experience short-term, seasonal low flow events, while catchments incorporating characteristics that are more robust towards fluctuations of water availability will show long-term sensitivities towards meteorological trends. This study emphasizes the importance of small-scale effects when dealing with low flow events.
title: Smart City Design Differences: Insights from Decision-Makers in Germany and the Middle East/North-Africa Region
Creators: name: Ringel, Marc
Publisher: name: MDPI
Year: 2021

description: Smart cities offer solutions to environmental, economic, and societal problems in urban agglomerations. We investigate the potential for mutual learning in smart city implementation by comparing German approaches (smaller, local projects) to projects implemented in the MENA region (bigger, national designs). We contrast the outside view on these projects with an inside perspective, surveying key decision-makers in five German and seven MENA smart cities. We assess motivation, technology options, and factors that drive or impede smart city implementation. We find strong similarities in the motives to engage in smart cities, offering common ground for mutual good practice exchange. Energy efficiency solutions and - to a lesser extent - renewable energies are of strong interest to policymakers in all countries. In contrast, the appraisal of mobility solutions strongly diverges, showing that technology deployment is far from being a simple "plug and play" solution. Considering these insights can facilitate the overall deployment of smart cities, not only in the surveyed countries but also in global manner.

description: We solve the equation of motion of boundary string field theory allowing generic boundary operators quadratic in $X$, and explore string theory non-perturbative vacua with massive state condensation. Using numerical analysis, a large number of new solutions are found. Their energies turn out to distribute densely in the range between the D-brane tension and the energy of the tachyon vacuum. We discuss an interpretation of these solutions as perturbative closed string states. From the cosmological point of view, the distribution of the energies can be regarded as the so-called landscape of string theory, as we have a vast number of non-perturbative string theory solutions including one with small vacuum energy.

description: For tailored functionalization of cellulose based papers, the interaction between paper fibers and functional additives must be understood. Planar cellulose surfaces represent a suitable model system for studying the binding of additives. In this work, polyelectrolyte multilayers (PEMs) are prepared by alternating dip-coating of the negatively charged cellulose derivate carboxymethyl cellulose and a polycation, either polydiallyldimethylammonium chloride (PDADMAC) or chitosan (CHI). The parameters varied during PEM formation are the concentrations (0.1–5 g/L) and pH (pH = 2–6) of the dipping solutions. Both PEM systems grow exponentially, revealing a high mobility of the polyelectrolytes (PEs). The pH-tunable charge density leads to PEMs with different surface topographies. Quartz crystal microbalance experiments with dissipation monitoring (QCM-D) reveal the pronounced viscoelastic properties of the PEMs. Ellipsometry and atomic force microscopy (AFM) measurements show that the strong and highly charged polycation PDADMAC leads to the formation of smooth PEMs. The weak polycation CHI forms cellulose model surfaces with higher film thicknesses and a tunable roughness. Both PEM systems exhibit a high water uptake when exposed to a humid environment, with the PDADMAC/carboxymethyl cellulose (CMC) PEMs resulting in a water uptake up to 60% and CHI/CMC up to 20%. The resulting PEMs are water-stable, but water swellable model surfaces with a controllable roughness and topography.

description: We analyze the time series of CaII H-line obtained from Hinode/SOT on the solar limb. The time-distance analysis shows that the axis of spicule undergos quasi-periodic transverse displacement at different heights from the photosphere. The mean period of transverse displacement is ~180 s and the mean amplitude is 1 arcsec. Then, we solve the dispersion relation of magnetic tube waves and plot the dispersion curves with upward steady flows. The theoretical analysis shows that the observed oscillation may correspond to the fundamental harmonic of standing kink waves.

Towards Automated Refactoring of Smelly Test Code

Publisher: name: Zenodo
Year: 2023

description: Test Refactoring improves the internal aspects of the software test without modifying its external behavior. However, the test code quality, i.e., design and writing standards, is not commonly prioritized within the industry. Test smells are anti-patterns that can harm the software testing understanding and maintenance. Although academia has constantly explored issues related to test smells and test code quality, there are still opportunities to improve how developers handle test code refactoring. This study initially provides a systematic mapping of the literature, which analyzed 42 primary works about test refactoring. The majority of the studies presented generic refactorings suitable for both production and test code. Some anti-patterns had multiple refactoring strategies, while others lacked a clear strategy. Existing tools have not evolved significantly since their inception, and many refactoring strategies have yet to be evaluated. Also, we investigated the effect of refactoring on the co-occurrence of test smells and observed that restructuring the test code can relocate or remove multiple test smell instances together. In this context, this study seeks to contribute with guidelines for refactoring multiple test smells, providing the order in which the refactoring should be applied to reduce the changes in test code. Furthermore, we intend to automate these guidelines and evaluate them with practitioners.

description: The nuclear structure dependence of direct reactions that remove a pair of like or unlike nucleons from a fast $^{12}$C projectile beam are considered. Specifically, we study the differences in the two-nucleon correlations present and the predicted removal cross sections when using $p$-shell shell-model and multi-$\hbarω$ no-core shell-model (NCSM) descriptions of the two-nucleon overlaps for the transitions to the mass $A$=10 projectile residues. The NCSM calculations use modern chiral two-nucleon and three-nucleon (NN+3N) interactions. The $np$-removal cross sections to low-lying $T$=0, $^{10}$B final states are enhanced when using the NCSM two-nucleon amplitudes. The calculated absolute and relative partial cross sections to the low energy $^{10}$B final states show a significant sensitivity to the interactions used, suggesting that assessments of the overlap functions for these transitions and confirmations of their structure could be made using final-state-exclusive measurements of the $np$-removal cross sections and the associated momentum distributions of the forward travelling projectile-like residues.

Cash transfer schemes

description: India leads all nations in numbers of maternal deaths, with poor, rural women contributing disproportionately to the high maternal mortality ratio. In 2005, India launched the world’s largest conditional cash transfer scheme, Janani Suraksha Yojana (JSY), to increase poor women’s access to institutional delivery, anticipating that facility-based birthing would decrease deaths. Indian states have taken different approaches to implementing JSY. Tamil Nadu adopted JSY with a reorganization of its public health system, and Gujarat augmented JSY with the state-funded Chiranjeevi Yojana (CY) scheme, contracting with private physicians for delivery services. Given scarce evidence of the outcomes of these approaches, especially in states with more optimal health indicators, this cross-sectional study examined the role of JSY/CY and other healthcare system and social factors in predicting poor, rural women’s use of maternal health services in Gujarat and Tamil Nadu. Using the District Level Household Survey (DLHS)-3, the sample included 1584 Gujarati and 601 Tamil rural women in the lowest two wealth quintiles. Multivariate logistic regression analyses examined associations between JSY/CY and other salient health system, socio-demographic, and obstetric factors with three outcomes: adequate antenatal care, institutional delivery, and Cesarean-section. Tamil women reported greater use of maternal healthcare services than Gujarati women. JSY/CY participation predicted institutional delivery in Gujarat (AOR = 3.9), but JSY assistance failed to predict institutional delivery in Tamil Nadu, where mothers received some cash for home births under another scheme. JSY/CY assistance failed to predict adequate antenatal care, which was not incentivized. All-weather road access predicted institutional delivery in both Tamil Nadu (AOR = 3.4) and Gujarat (AOR = 1.4). Women’s education predicted institutional delivery and Cesarean-section in Tamil Nadu, while husbands’ education predicted institutional delivery in Gujarat. Overall, assistance from health financing schemes, good road access to health facilities, and socio-demographic and obstetric factors were associated with differential use of maternity health services by poor, rural women in the two states. Policymakers and practitioners should promote financing schemes to increase access, including consideration of incentives for antenatal care, and address health system and social factors in designing state-level interventions to promote safe motherhood.

description: After some introductory discussion of the definition of Finsler spacetimes and their symmetries, we consider a class of spherically symmetric and static Finsler spacetimes which are small perturbations of the Schwarzschild spacetime. The deviations from the Schwarzschild spacetime are encoded in three perturbation functions $ϕ_0(r)$, $ϕ_1(r)$ and $ϕ_2(r)$ which have the following interpretations: $ϕ_0$ perturbs the time function, $ϕ_1$ perturbs the radial length measurement and $ϕ_2$ introduces a spatial anisotropy which is a genuine Finsler feature. We work out the equations of motion for freely falling particles and for light rays, i.e. the timelike and lightlike geodesics, in this class of spacetimes, and we discuss the bounds placed on the perturbation functions by observations in the Solar system.

description: Symmetries represent a fundamental constraint for physical systems and relevant new phenomena often emerge as a consequence of their breaking. An important example is provided by space- and time-translational invariance in statistical systems, which hold at a coarse-grained scale in equilibrium and are broken by spatial and temporal boundaries, the former being implemented by surfaces - unavoidable in real samples - the latter by some initial condition for the dynamics which causes a non-equilibrium evolution. While the separate effects of these two boundaries are well understood, we demonstrate here that additional, unexpected features arise upon approaching the effective edge formed by their intersection. For this purpose, we focus on the classical semi-infinite Ising model with spin-flip dynamics evolving out of equilibrium at its critical point. Considering both subcritical and critical values of the coupling among surface spins, we present numerical evidence of a scaling regime with universal features which emerges upon approaching the spatio-temporal edge and we rationalise these findings within a field-theoretical approach.

Publisher: name: Zenodo
Year: 2023

description: As internet users progressively increase, nodes and connections' latency, speed, and mobility have become significant concerns. In this dynamic scenario, Heterogeneous Networks predominate, in which communications between devices of different technologies, manufacturers, capacities, and structures occur. Most communications on these networks work through the TCP protocol, which wastes much of the resources available in networks and communications. Using some resources offered by M-PolKA, this research aims to investigate methods of optimization of dynamic multicast connections in heterogeneous environments to provide an alternative to the current demands of computer networks, mitigate the current limitations existing in the current TCP architecture and explore the use of natively multipath protocols, such as the QUIC protocol.

description: Nowadays, the digital world is most focused on storage space and speed. With the growing demand for better bandwidth utilization, efficient image data compression techniques have emerged as an important factor for image data transmission and storage. To date, different approaches to image compression have been developed like the classical predictive coding, popular transform coding and vector quantization. Several second generation coding schemes or the segmentation based schemes are also gaining popularity. Practically efficient compression systems based on hybrid coding which combines the advantages of different traditional methods of image coding have also been developed over the years. In this paper, different hybrid approaches to image compression are discussed. Hybrid coding of images, in this context, deals with combining two or more traditional approaches to enhance the individual methods and achieve better-quality reconstructed images with higher compression ratio. Literature on hybrid techniques of image coding over the past years is also reviewed. An attempt is made to highlight the neuro-wavelet approach for enhancing coding efficiency.

description: We study charged black hole solutions in Einstein-Gauss-Bonnet theory with the dilaton field which is the low-energy effective theory of the heterotic string. The spacetime is D-dimensional and assumed to be static and spherically symmetric with the $(D-2)$-dimensional constant curvature space and asymptotically flat. The system of the basic equations is complex and the solutions are obtained numerically. We identify the allowed parameter region where the black hole solutions exist, and show configurations of the field functions in D=4 -- 6 and 10. We also show the relations of the physical quantities of the black holes such as the horizon radius, the mass, the temperature, and so on, and find several results. The forms of the allowed parameter regions are different depending on the dimension. There is no extreme black hole solution with T=0 that can be obtained by taking the limit of the non-extreme solutions within the parameter range we chose. Entropy of the black holes in the dilatonic theory is always larger than that in the non-dilatonic theory. Our analysis includes the higher order term of the dilaton field which is not in our previous works. Its effect remarkably appears in five dimensions and is given in the appendix. By our analysis it is found that the properties of the black hole solutions strongly depend on the dimension, charge, existence of the dilaton field. Hence both the detailed analyses of the individual systems and the investigations from the systematic point of view are important.

description: The future of science will be determined primarily by the methods and tools that can be used to effectively analyze the huge amounts of data generated by the common use of digital media in scholarly communication, conversations, work processes and social structures. These characteristics, which are subsumed under the term data-intensive science, change the nature of scientific work in the most sustainable way. And most importantly, such expressions as the fact that scientific collaboration is increasingly embedded in a globally connected environment and the growth rate of scientific output in the top ten countries is increasing exponentially and this output is expressed above all by non-traditional, highly dynamic, interconnected assets such as data sets, software, ontologies, slides, videos, blog entries, are responsible for the manifold challenges for Scientometric investigations. COLLNET 2018 has met these challenges and provided an excellent opportunity to discuss the phenomena of collaboration in science, their impact on productivity, innovation, and benefits, and outcomes for individuals, institutions, and economies worldwide. The COLLNET Conference Series and the active COLLNET community have been playing for almost two decades an outstanding role in scholarly communication for improving co-work and collaboration among researchers and practitioners all over the world. This global interdisciplinary research network is to comprise the prominent scientists, who work at present in the field of quantitative science studies. COLLNET 2018 was also a great opportunity for both researchers and practitioners to share experiences, ideas, and research results on all aspects of Webometrics, Informetrics and Scientometrics and to open new avenues for possible research collaborations in the future. This Procedia includes selected papers presented at the 14th International Conference on Webometrics, Informetrics and Scientometrics (WIS) & 19th COLLNET Meeting, which took place during 05 to 08 December 2018 in the University of Macau, Macau. The Conference was organized by the Department of Computer and Information Science, University of Macau, in collaboration with Digital Information Research Labs, India and the COLLNET Coordination Centre, Germany.

description: This paper addresses gender differences in international research collaboration measured through international coauthorship. The study is based on a dataset consisting of 5,554 Norwegian researchers and their publication output during a three-year period (43,641 publications). Two different indicators are calculated. First, the share of researchers that have been involved in international collaboration measured by co-authorship, and second, the share of their publications with international co-authorship. We then develop an index which takes both these indicators into account: The Gender Difference Collaboration Index. The study shows that there are distinct gender differences in international research collaboration in Norway at an overall level. However, when the data is analyzed by scientific field, academic position and publication productivity of the researchers, the gender differences are less pronounced and in some cases, women have higher collaboration rates than men. The differences are largest for personnel in recruitment positions and for less productive researchers.

description: We describe two-field optical techniques to control interactions in Feshbach resonances for two-body scattering in ultra-cold gases. These techniques create a molecular dark state in the closed channel of a magnetically tunable Feshbach resonance, greatly suppressing optical scattering compared to single optical field methods. The dark-state method enables control of the effective range, by creating narrow features that modify the energy dependence of the scattering phase shift, as well as control of the elastic and inelastic parts of the zero-energy s-wave scattering amplitude. We determine the scattering length and the effective range from an effective range expansion, by calculating the momentum-dependent scattering phase shift from the two-body scattering state.

description: The recently discovered 125 GeV boson appears very similar to a Standard Model Higgs, but with data favoring an enhanced h to gamma gamma rate. A number of groups have found that fits would allow (or, less so after the latest updates, prefer) that the h-t-tbar coupling have the opposite sign. This can be given meaning in the context of an electroweak chiral Lagrangian, but it might also be interpreted to mean that a new colored and charged particle runs in loops and produces the opposite-sign hGG amplitude to that generated by integrating out the top, as well as a contribution reinforcing the W-loop contribution to hFF. In order to not suppress the rate of h to WW and h to ZZ, which appear to be approximately Standard Model-like, one would need the loop to "overshoot," not only canceling the top contribution but producing an opposite-sign hGG vertex of about the same magnitude as that in the SM. We argue that most such explanations have severe problems with fine-tuning and, more importantly, vacuum stability. In particular, the case of stop loops producing an opposite-sign hGG vertex of the same size as the Standard Model one is ruled out by a combination of vacuum decay bounds and LEP constraints. We also show that scenarios with a sign flip from loops of color octet charged scalars or new fermionic states are highly constrained.

description: The numerous results obtained with asteroseismology thanks to space missions such as CoRoT and Kepler are providing a new insight on stellar evolution. After five years of observations, CoRoT is going on providing high-quality data. We present here the analysis of the double star HD169392 complemented by ground-based spectroscopic observations. This work aims at characterizing the fundamental parameters of the two stars, their chemical composition, the acoustic-mode global parameters including their individual frequencies, and their dynamics. We have analysed HARPS observations of the two stars to retrieve their chemical compositions. Several methods have been used and compared to measure the global properties of acoustic modes and their individual frequencies from the photometric data of CoRoT. The new spectroscopic observations and archival astrometric values suggest that HD169392 is a wide binary system weakly bounded. We have obtained the spectroscopic parameters for both components, suggesting the origin from the same cloud. However, only the mode signature of HD169392 A has been measured within the CoRoT data. The signal-to-noise ratio of the modes in HD169392B is too low to allow any confident detection. We were able to extract mode parameters of modes for l=0, 1, 2, and 3. The study of the splittings and inclination angle gives two possible solutions with splittings and inclination angles of 0.4-1.0 muHz and 20-40 degrees for one case and 0.2-0.5 muHz and 55-86 degrees for the other case. The modeling of this star with the Asteroseismic Modeling Portal led to a mass of 1.15+/-0.01 Ms, a radius of 1.88+/-0.02 Rs, and an age of 4.33+/-0.12 Gyr, where the uncertainties are the internal ones.

description: We place general constraints on the luminosity and mass of hot X-ray emitting gas residing in extended "hot halos" around nearby massive galaxies. We examine stacked images of 2165 galaxies from the 2MASS Very Isolated Galaxy Catalog (2MVIG), as well as subsets of this sample based on galaxy morphology and K-band luminosity. We detect X-ray emission at high confidence (ranging up to nearly 10σ) for each subsample of galaxies. The average L_X within 50 kpc is 1.0\pm0.1 (statistical) \pm0.2 (systematic) x10^40 erg/s, although the early-type galaxies are more than twice as luminous as the late-type galaxies. Using a spatial analysis, we also find evidence for extended emission around five out of seven subsamples (the full sample, the luminous galaxies, early-type galaxies, luminous late-type galaxies, and luminous early-type galaxies) at 92.7%, 99.3%, 89.3%, 98.7%, and 92.1% confidence, respectively. Several additional lines of evidence also support this conclusion and suggest that about 1/2 of the total emission is extended, and about 1/3 of the extended emission comes from hot gas. For the sample of luminous galaxies, which has the strongest evidence for extended emission, the average hot gas mass is 4x10^9 Msun within 50 kpc and the implied accretion rate is 0.4 Msun/yr.

description: Judging credibility is an important skill that 21st-century learners and citizens should possess as the world continues to present a seemingly infinite number of information from a wide variety of sources- not all of them truthful. This research sought to determine whether students can judge the difference between credible and non-credible sources with and without the use of the CRAAP instrument and whether there is a significant difference between the results of the classes involved. The researcher used the descriptive research design with purposive sampling with ninety (90) Grade 10 students as the respondents. The researcher gave a post-test and a pre-test and also conducted a focus group discussion to verify the results. The researcher found that students find it difficult to evaluate credibility without an instrument as they don't have a guide in what to consider in doing so. It is also measured a significant difference (t=2.00**) between the pre-test and post-test results in all sections, which means that the CRAAP test leads students to the aspects that should be considered in judging or evaluating credibility serves as an effective practice material to develop said skill. Students in the different sections also had similar difficulties and marked improvements (pre-test = 1.27 ns, post-test = 1.35 ns), which the CRAAP test helped address. The CRAAP test helps all kinds of students improve, given that diverse students have diverse ways of learning for the CRAAP test targets a specific skill for the students to improve on.

description: In this paper, we extend some ideas of statistical physics to describe the properties of human mobility. From a physical point of view, we consider the statistical empirical laws of private cars mobility, taking advantage of a GPS database which contains a sampling of the individual trajectories of 2% of the whole vehicle population in an Italian region. Our aim is to discover possible "universal laws" that can be related to the dynamical cognitive features of individuals. Analyzing the empirical trip length distribution we study if the travel time can be used as universal cost function in a mesoscopic model of mobility. We discuss the implications of the elapsed times distribution between successive trips that shows an underlying Benford's law, and we study the rank distribution of the average visitation frequency to understand how people organize their daily agenda. We also propose simple stochastic models to suggest possible explanations of the empirical observations and we compare our results with analogous results on statistical properties of human mobility presented in the literature.
Novas perspectivas de diferenciação de serviços em redes através das Redes Centradas na Informação

description: As Redes Centradas na Informação (ICN) apresentam um novo modelo de comunicação com foco nos dados, isso permite desvincular esses dados de sua origem, uma abordagem que pode potencializar operações que são limitadas pela rede IP atual. Com essa nova perspectiva, a ICN oferece um modelo de comunicação pensado de acordo com o padrão atual de consumo de conteúdos da Internet. Os usuários e as aplicações modernas da Internet buscam recuperar conteúdo sem se preocupar onde eles estão armazenados. Embora a ICN atenda ao requisito imposto, os dados trafegados são tratados sem distinção, independentemente do tipo de aplicação que os geraram, com base no melhor esforço e sem garantias. Em um cenário realista, a rede tende a operar com um tráfego elevado de pacotes oriundos de aplicações e dispositivos heterogêneos. Dessa forma, a rede precisa estar ciente da diferenciação de serviços para oferecer um tratamento adequado aos fluxos de dados de acordo com seus requisitos. Neste contexto, este trabalho investiga uma arquitetura de Rede de Dados Nomeados (NDN), uma abordagem de ICN, ciente da diferenciação de serviços para oferecer uma melhor qualidade de serviço aos usuários e melhor gerenciamento do tráfego da rede. A solução proposta busca maximizar os benefícios já oferecidos pela NDN e explorar questões arquiteturais que têm potencial de alavancar a implantação da NDN ciente de diferenciação de serviços.
