description: Weeds are consider as a significant important biological indicator of crop production resulting to yield loss of about 50%. Identification of weeds is very difficult from their morphological features. Despite wees are the real challenge in farming in the developed, developing and underdeveloped countries. Nevertheless, weeds ar also part of primary producers. Major constrain of crop production are weeds but they are also consider as important aspect of agricultural system in the world. Weeds are wild plants grow in an environment without the contribution of any human activities that that have positive or negative impact to the environment. The aim of the study is to documents weeds of family Boraginaceae and agricultural crops grown in Taif region of Saudi Arabian kingdom in a mountain with an elevation level of (Area A = Al sail 1700 m, Area B = Al Wahat and Al Watit 1500, C = Leeih 1500, D = AL Gaim and Saisad 1500, F = E = Al Shafa 2200 m, F = AL Hada = 2000 m). The study was carried out based on enviromental survey. Diverse number of weeds were identified and collected from the examined study area. Results revealed aggressive weeds species. Echium vulgars, Heliotropium currsivicium and Sisymbrium orientale. Similarly, ten agricultural crops were documented from the study area; Portulaca oleracea,Ficus carica, Phoenix dactylifera, Solanum melongena, Punica granatum, Solanum lycopersicum, Vitis spp, Vicia faba, Cucurbita pepo and Rosa damascene. Findings from the studyof the will aid management control and proposing research toward improved new weed control measures. Also has provided insight on purposeful weeds control in Taif Area.

description: In this communication, we present a new processing method for obtaining oxide ceramic composites based on the ionotropic gelation technique. Nextel 610 fiber fabrics were infiltrated by an alumina-zirconia suspension with a total solid content of 50 vol.% and alginate as the binder. Subsequently, the suspension was slowly cross-linked by adding Al3+ cations and transferred to a gel state. The gelled fabric layers could be easily cut, stacked and shaped, as well as joined to other ceramic materials and composites. Furthermore, the fiber content could be adjusted by pressing the layers together. In summary, the composites produced with this technique presented a very good fiber bundle infiltration, matrix with fine porosity and excellent mechanical properties. Nextel 610/alumina-zirconia composites sintered at 1200°C for 1 h showed bending strength of 306 MPa, interlaminar shear strength of 9.8 MPa and nominal fracture toughness of 13.6 MPa m0.5.

description: Universal factors associated with the emission of a soft boson in gauge theories and gravity, formulated in the light-cone gauge, are presented. The inverse-soft method, for constructing higher-point amplitudes from lower-point ones, using these factors is reviewed. These ideas are then examined in (light-cone) superspace and applied to both the N=4 super Yang-Mills and N=8 supergravity theories. One highlight is a compact result for the quartic interaction vertex in N=8 supergravity, a crucial ingredient for finiteness analyses.

description: We experimentally isolate, characterize and coherently control up to six individual nuclear spins that are weakly coupled to an electron spin in diamond. Our method employs multi-pulse sequences on the electron spin that resonantly amplify the interaction with a selected nuclear spin and at the same time dynamically suppress decoherence caused by the rest of the spin bath. We are able to address nuclear spins with interaction strengths that are an order of magnitude smaller than the electron spin dephasing rate. Our results provide a route towards tomography with single-nuclear-spin sensitivity and greatly extend the number of available quantum bits for quantum information processing in diamond.
Alternance études-emploi au Sénégal, quels effets dans le supérieur ?

description: L'enseignement supérieur sénégalais fait face, depuis plus d'une décennie, à de nombreuses crises d'ordre infrastructurel, social, financier, pédagogique : hausse des effectifs sans augmentation relative des ressources matérielles, humaines, retard dans la perception des bourses mensuelles, difficultés d'accès à l'emploi… L'instauration du système LMD depuis les années 2000 a fait couler beaucoup d'encre. Certains volets, tels que la professionnalisation des formations, tardent toujours à être réalisés. Les étudiants découvrent tardivement le milieu professionnel. Nous notons par ailleurs « un déséquilibre au niveau de la répartition des étudiants dans les différents domaines d'études avec une forte concentration dans les filières dites littéraires avec un taux de 70 %, alors que ceux des filières scientifiques, techniques et professionnelles ne représentent que 30 % des effectifs dans les universités publiques » (CNAES 2013). En 2013, le diagnostic de la Concertation nationale sur l'avenir de l'enseignement supérieur (CNAES), réaffirme l'option stratégique de promotion de cycles professionnels courts dans le système d'enseignement supérieur. 
Le marché du travail est en outre, caractérisé par une surabondance de diplômés de formations générales longues, des créations d'emplois beaucoup plus lentes que la production de diplômés et une absence d'adéquation entre la demande de travail des entreprises et l'offre des diplômés. Leur insertion professionnelle se fait généralement bien après la formation, avec un délai d'insertion supérieur à un (1) an pour 74% des diplômés du supérieur (PSE2014).
Cette problématique nous incite à pousser notre réflexion sur la stratégie à adopter dans le supérieur, afin de leur assurer un accès facile à l'emploi, de réduire la prise en charge de l'Etat, gage de stabilité durable de l'enseignement supérieur sénégalais.
Nous utilisons une extension de l'équation de salaire de Mincer (1974), que nous estimons à travers la procédure en deux étapes de Heckman (1979). Les résultats indiquent qu'au Sénégal, alterner les études supérieures à l'emploi est favorable au Revenu. Un écart de revenu est constaté entre les individus ayant combiné les études à l'emploi, par rapport à ceux qui ne l'ont pas effectué. 
Ces résultats pourraient guider les décideurs dans leur politique éducative à mettre en œuvre dans l'enseignement supérieur.
Carbon, plant and microbial dynamics in Low-Arctic tundra

description: Anthropogenic climate change threatens the stability of Arctic C stores. Soil microbes are central to the C balance of ecosystems as decomposers of soil organic matter and as determinants of plant diversity. In four experiments in the tundra, I address critical gaps in our understanding of the role of soil microbial communities in the response of an Arctic ecosystem to climate change. My objectives were 1) to asses the role of mycorrhizal networks (MN) in plant-plant interactions; 2) to determine the effects of warming and fertilization on the ectomycorrhizal (ECM) community of Betula nana; 3) to determine the effect of warming on soil fungi and bacteria over time; 4) to assess the role of the mycorrhizal symbiosis in C-allocation to rhizosphere organisms. I show that MNs exist in tundra and facilitate transfer of C among Betula nana individuals, but not among the other plants examined. C-transfer among Betula nana pairs through MNs represented 5.5 ± 2.2% of photosynthesis, total belowground transfer of C was 10.7 ± 2.1%. My results suggest that C-transfer through MNs may alter plant interactions, increasing competition by Betula nana, and that this will be enhanced with warming. I show that warming leads to a significant increase of fungi with proteolytic capacity, particularly Cortinarius spp., and a reduction of fungi with high affinities for labile N, especially Russula spp. My findings suggest that warming will alter the ECM community and nutrient cycling, which may facilitate Betula nana in tundra. I show that warming leads to a 28% and 22% reduction in the richness of soil fungi and bacteria in tundra, respectively, as well as corresponding declines in diversity. My data agree with reductions in plant community richness with warming at this site, and suggest that warming will reduce total community diversity in tundra. I show that Gram-negative bacteria and a species-specific community of mycorrhizal fungi are the primary consumers of rhizodeposit C among tundra shrubs. Together, these results strongly suggest that soil microbes play a critical role in plant community dynamics and C-cycling in Arctic tundra, and that this role will become increasingly important as climate warms.

Electron spins at dangling-bond sites near the silicon surface are identified as the source of the nuclear hyperpolarization. This novel polarization method open new avenues for the fabrication of surface engineered nanostructures to create high nuclear-spin polarized solutions without introducing contaminating radicals, and for the study of molecules adsorbed onto surfaces.

description: This research aims to investigate the role of micro-entrepreneurship in empowering Arab refugee women and alleviating poverty in their communities. The study explores the use of micro-enterprises as a mechanism for refugees' empowerment and evaluates its impact on creating a sustainable economy. The objectives include assessing the economic status of refugee women in Lebanon and determining the role of the Arabian government in enhancing women's empowerment. The research sampled 200 women refugees, and it was found that micro-enterprises play a key role in poverty alleviation, but there are other intervening factors such as government commitment, societal engagement, and non-governmental organizations. The study also found that displaced women prefer to find other pathways and networks to support their enterprising activities rather than engaging with formal support agencies. The research suggests that the government should seek other ways of promoting business and helping women and children meet their basic needs when displaced. Finally, the study explores the effectiveness and impact of available pathways for support and advice for displaced and refugee women and analyses the extent to which entrepreneurship is a sustainable conduit for poverty alleviation and empowerment in socio-politically volatile circumstances.

Linear optical response from the odd parity Bardasis-Schrieffer mode in locally non-centrosymmetric superconductors

description: On the recent report of a magnetic field induced first order transition between an even-parity superconductivity and an odd-parity superconductivity in $\mathrm{CeRh_{2}As_{2}}$, the microscopic physics is still under investigation. However, if, in the vicinity of this transition, the coupling strengths of the even and odd pairing channels are comparable, a particle-particle excitonic collective mode referred to as the Bardasis-Schrieffer (BS) mode should generically exist below the pair-breaking continuum. This BS mode can couple to the light and thus affect the optical response of the superconductor, as it arises from a pairing channel with the parity opposite to that of the ground state pairs. Here, by using a generic bilayer model Hamiltonian for the electronic degree of freedom, which is globally centrosymmetric despite each layer being locally non-centrosymmetric, we study the change of the excitation gap of the BS mode with respect to the out-of-plane magnetic fields and demonstrate that its coupling to the light is possible even in the linear response regime. The linear coupling is attributed to the presence of multiple electronic bands, which is a generic feature of a bilayer system. Our result shows the microwave absorption as the signature of the BS mode, and hence a smoking gun signature of the parity-switching at the transition between two superconducting phases.

description: Quantum speed limits such as the Mandelstam-Tamm or Margolus-Levitin bounds offer a quantitative formulation of the energy-time uncertainty principle that constrains dynamics over short times. We show that the spectral form factor, a central quantity in quantum chaos, sets a universal state-independent bound on the quantum dynamics of a complete set of initial states over arbitrarily long times, which is tighter than the corresponding state-independent bounds set by known speed limits. This bound further generalizes naturally to the real-time dynamics of time-dependent or dissipative systems where no energy spectrum exists. We use this result to constrain the scrambling of information in interacting many-body systems. For Hamiltonian systems, we show that the fundamental question of the fastest possible scrambling time -- without any restrictions on the structure of interactions -- maps to a purely mathematical property of the density of states involving the non-negativity of Fourier transforms. We illustrate these bounds in the Sachdev-Ye-Kitaev model, where we show that despite its "maximally chaotic" nature, the sustained scrambling of sufficiently large fermion subsystems via entanglement generation requires an exponentially long time in the subsystem size.

description: In this paper we propose a new approach to estimation of the tail exponent in financial stock markets. We begin the study with the finite sample behavior of the Hill estimator under α-stable distributions. Using large Monte Carlo simulations, we show that the Hill estimator overestimates the true tail exponent and can hardly be used on samples with small length. Utilizing our results, we introduce a Monte Carlo-based method of estimation for the tail exponent. Our proposed method is not sensitive to the choice of tail size and works well also on small data samples. The new estimator also gives unbiased results with symmetrical confidence intervals. Finally, we demonstrate the power of our estimator on the international world stock market indices. On the two separate periods of 2002-2005 and 2006-2009, we estimate the tail exponent.

description: Persistent identifiers (PIDs) are central to FAIR research data management and have become an essential component of applications and services. Also, PID-related metadata are central to the FAIRness of research resources and support their reusability and the reproducibility of research. However, with the growing importance of PIDs in everyday research and more and more also in cultural contexts, the requirements for their efficient usability are also increasing. At the same time, users are confronted with a great variety of very different PID systems and implementation possibilities. The DFG funded project “PID Network Germany” therefore aims to establish a network of stakeholders around the persistent identification of people, organisations, and resources in the field of digital communication in science and culture, which promotes the dissemination and connection of PID systems in Germany. The focus is also on identifying needs and optimization potential for existing PID systems and embedding them in international knowledge graphs. The project findings should lead to recommendations in the order to create a national PID roadmap for Germany. The PID Network Germany complements the endeavor of “PID4NFDI” in particular on the policy level and both projects agreed to closely collaborate. PID4NFDI is a proposal for the Initialization Phase of Base4NFDI, which is currently under review for funding. The central objective of PID4NFDI is to consolidate and evolve the PID service landscape within NFDI at all levels: technical, organisational, methodological, and in communication.

description: We present a theoretical analysis of the temperature-magnetic field-concentration phase diagram of the multiferroic Mn$_{1-x}$M$_{x}$WO$_{4}$ (M=Fe, Zn, Mg), which exhibits three ordered phases, with collinear and non-collinear incommensurate and with a commensurate magnetic order. The middle phase is also ferroelectric. The analysis uses a semi-phenomenological Landau theory, based on a Heisenberg Hamiltonian with a single-ion anisotropy. With a small number of adjustable parameters, the Landau theory gives an excellent fit to all three transition lines, as well as the magnetic and the ferroelectric order parameters. The fit of the magnetic and ferroelectric order parameters is further improved by including the effect of fluctuations near the transitions. We demonstrate the highly frustrated nature of these materials and suggest a simple explanation for the dramatic effects of doping with different magnetic ions at the Mn sites. The model enables an examination of different sets of exchange couplings that were proposed by a number of groups. Small discrepancies are probably a consequence of small errors in the experimental magnetic parameters. In addition, using the Ginzburg criterion we estimate the temperature range in which fluctuations of the order parameters become important.

description: The signals from international pulsar timing arrays have presented a hint of gravitational stochastic background in nHz band frequency. Further confirmation will be based on whether the signals follow the angular correlation curves formulated by the overlap reduction functions, known as Hellings-Downs curves. This paper investigates the non-linear corrections of overlap reduction functions in the present of non-Gaussianity, in which the self-interaction of gravity is first taken into considerations. Based on perturbed Einstein field equations for the second order metric perturbations, and perturbed geodesic equations to the second order, we obtain non-linear corrections for the timing residuals of pulsar timing, and theoretically study corresponding overlap reduction functions for pulsar timing arrays. There is order-one correction for the overlap reduction functions from the three-point correlations of gravitational waves, and thus the shapes of the overlap reduction functions with non-linear corrections can be distinguished from the Hellings-Downs curves.

description: We observe a correlation between the slope of radio lateral distributions, and the mean muon pseudorapidity of 59 individual cosmic-ray-air-shower events. The radio lateral distributions are measured with LOPES, a digital radio interferometer co-located with the multi-detector-air-shower array KASCADE-Grande, which includes a muon-tracking detector. The result proves experimentally that radio measurements are sensitive to the longitudinal development of cosmic-ray air-showers. This is one of the main prerequisites for using radio arrays for ultra-high-energy particle physics and astrophysics.

Anatomy of energy pathways in the subtropical gyre of the North Atlantic
Creators: name: Tedesco, Pauline
Publisher: name: Zenodo
Year: 2023

description: The North Atlantic is a key region in the global ocean circulation and plays a central role in regulating our climate. Its circulation is constrained by energy transfers between time-mean currents at the basin-scale and time-varying ("eddy") flows from hundreds to order one kilometer, including low-frequency mesoscale and submesoscale currents and high-frequency internal waves. Here, we evaluate the eddy kinetic energy budget in the subtropical gyre of the North Atlantic (STG), with a focus on the contribution of the different flows. Sources and sinks of energy, non-local effects — spatial energy redistribution — and eddy-mean energy conversions are evaluated using two state-of-the-art numerical simulations, one without and with a tidal forcing. We show that the energy budget varies within the STG, from the leading-order energy balances to the contributions of time-varying flows. In the STG's Interior, where submesoscale currents and internal waves dominate the eddy reservoir, the main energy sources correspond to wind, tide, and baroclinic instability. At western and eastern boundaries, energy balances are the most complex. (i) Another major energy source is due to mean to eddy energy conversion and (ii) energy is significantly redistributed by non-local effects. At the western boundary, eddy-mean interactions and non-local effects primarily involve mesoscale and submesoscale currents and also internal tides (net contributions increased by a factor >2 in the tidal scenario). At the eastern boundary, both energy contributions primarily involve internal tides (net contribution increased by a factor of 3-4 in the tidal scenario). Our results emphasise the substantial impact of internal tides on the time-mean circulation of the North Atlantic's STG. This advocates for representing their contributions, along with the ones of mesoscale and submesoscale currents, in ocean models.

description: We present an empirical s-process abundance distribution derived with explicit knowledge of the r-process component in the low-metallicity globular cluster M22. We have obtained high-resolution, high signal-to-noise spectra for 6 red giants in M22 using the MIKE spectrograph on the Magellan-Clay Telescope at Las Campanas Observatory. In each star we derive abundances for 44 species of 40 elements, including 24 elements heavier than zinc (Z=30) produced by neutron-capture reactions. Previous studies determined that 3 of these stars (the "r+s group") have an enhancement of s-process material relative to the other 3 stars (the "r-only group"). We confirm that the r+s group is moderately enriched in Pb relative to the r-only group. Both groups of stars were born with the same amount of r-process material, but s-process material was also present in the gas from which the r+s group formed. The s-process abundances are inconsistent with predictions for AGB stars with M =< 3 Msun and suggest an origin in more massive AGB stars capable of activating the Ne-22(alpha,n)Mg-25 reaction. We calculate the s-process "residual" by subtracting the r-process pattern in the r-only group from the abundances in the r+s group. In contrast to previous r- and s-process decompositions, this approach makes no assumptions about the r- and s-process distributions in the solar system and provides a unique opportunity to explore s-process yields in a metal-poor environment.

Complete Genuine Multipartite Entanglement Monotone

description: A complete characterization and quantification of entanglement, particularly the multipartite entanglement, remains an unfinished long-term goal in quantum information theory. As long as the multipartite system is concerned, the relation between the entanglement contained in different partitions or different subsystems need to take into account. The complete multipartite entanglement measure and the complete monogamy relation is a framework that just deals with such a issue. In this paper, we put forward conditions to justify whether the multipartite entanglement monotone (MEM) and genuine multipartite entanglement monotone (GMEM) are complete, completely monogamous, and tightly complete monogamous according to the feature of the reduced function. Especially, with the assumption that the maximal reduced function is nonincreasing on average under LOCC, we proposed a class of complete MEMs and a class of complete GMEMs via the maximal reduced function for the first time. By comparison, it is shown that, for the tripartite case, this class of GMEMs is better than the one defined from the minimal bipartite entanglement in literature under the framework of complete MEM and complete monogamy relation. In addition, the relation between monogamy, complete monogamy, and the tightly complete monogamy are revealed in light of different kinds of MEMs and GMEMs.

description: En 2019, les «affaires pédophiles» font encore régulièrement manchette dans les journaux québécois. Notre thèse propose donc une analyse actuelle du discours de la presse écrite sur la question de la pédophilie et du pédophile, et ce, à travers trois grands quotidiens : Le Soleil, La Presse et Le Devoir. Contrairement à ce que prétend la littérature scientifique, la pédophilie n’est plus simplement abordée tel un crime immonde à réprouver. Elle est aussi associée à un tabou social pouvant nuire à la liberté d’expression artistique. Ceci dit, ce phénomène renvoie encore et toujours à un problème très grave sur lequel le citoyen se doit absolument d’intervenir. En effet, la manière dont les journaux traitent la pédophilie laisse croire que les pédophiles ont désormais infiltré nos organes de contrôle social. Cette perte de confiance à l’endroit des autorités officielles se traduit notamment par une mise en avant de l’action citoyenne dans la « lutte aux pédophiles » ou autrement dit, par la promotion de parents justiciers et de victimes héroïques s’étant eux-mêmes faits justice. À cet égard, la représentation de certains acteurs sociaux nous renseigne sur ce qui est jugé désirable et sur les interventions appropriées en matière de pédophilie. Les pédophiles ne sont plus considérés par la presse comme étant les seuls coupables de ce problème social. Tous ceux et celles qui n’interviennent pas suffisamment le sont tout autant, donnant lieu au phénomène des mères complices et des autorités (sociales et parentales) incapables. Enfin, et à l’instar des études récentes sur les médias, on note une grande part de subjectivité journalistique dans nos articles. Effectivement, les auteurs n’hésitent pas à partager leurs opinions et leurs états d’âme en ce qui concerne l’univers de la pédophilie, favorisant du même coup ce que Taguieff (2006) appelle des logiques conspirationnistes.

description: We outline the theory of sets with distributive operations: multishelves and multispindles, with examples provided by semi-lattices, lattices and skew lattices. For every such a structure we define multi-term distributive homology and show some of its properties. The main result is a complete formula for the homology of a finite distributive lattice. We also indicate the answer for unital spindles and conjecture the general formula for semi-lattices and some skew lattices. Then we propose a generalization of a lattice as a set with a number of idempotent operations satisfying the absorption law.

description: BACKGROUND – Pharmaceutical use for the secondary prevention of cardiac events after acute myocardial infarction (AMI) is widespread, but there is uncertainty as to how (or if) patients use their medicines over long periods of time. Accordingly, the purpose of this thesis is 1) to measure persistence with and adherence to ACE inhibitors, beta blockers and statins, following AMI in BC, 2) to construct a conceptually-driven model of adherence and persistence, with patient demographic, socioeconomic, health status and pharmaceutical use variables, and 3) to determine whether regional variation in adherence and persistence rates exist. METHODS – Using administrative data from the BC Linked Health Database and PharmaNet, I studied a cohort of BC patients who were hospitalized for their first AMI between 2001 and 2005. I measured persistence as days to first 90-day gap in medication, and I measured adherence in two ways: the proportion of days covered (PDC) between first prescription and first 90-day gap, and PDC in the first year post-discharge (1-year PDC). Rates of persistence and adherence were analyzed using Cox proportional hazards models and multivariate logistic regression respectively. RESULTS – Patient persistence and adherence with medication was generally high, with 70% of ACE inhibitor users, 73% of beta blocker users and 78% of statin users persisting at one year. Nearly 89% of users of any class were persistent at 1 year, as opposed to 52% of users of all three concurrently. Factors consistently associated with high adherence and persistence were high income, private insurance, the use of more drug classes (both before and after AMI), and being in the mid-range of age (60-69 years). Sex had mixed effects between classes, with women having higher persistence and adherence with beta blockers and lower with ACE inhibitors. Some regional variation existed, but effects were small and inconsistent. CONCLUSION – Most AMI patients in BC use at least one drug for several years after AMI, but few persist with all three recommended classes. Important next steps include determining the clinical outcomes of adherence and persistence, especially with drug combinations, to more clearly define optimal secondary prevention practices following AMI.

description: Proton and carbon ion therapy is an emerging technique used for the treatment of solid cancers. The monitoring of the dose delivered during such treatments is still a matter of research. A possible technique exploits the information provided by single photon emission from nuclear decays induced by the irradiation. This paper reports the measurements of the spectrum and rate of such photons produced from the interaction of a 80 MeV/u fully stripped carbon ion beam at the Laboratori Nazionali del Sud of INFN, Catania, with a Poly-methyl methacrylate target. The differential production rate for photons with energy E > 2 MeV and emitted at 90 degree is found to be $dN_γ/(dN_C dΩ)=(2.92\pm 0.19)\times 10^{-2}$sr$^{-1}$.

description: In einer mittlerweile überwiegend digitalen Wissenschaftslandschaft ist die dauerhafte und verlässliche Identifizierung der mit
 Forschungsprozessen verknüpften Ressourcen, seiner Akteure und ihrer Publikationen mittels Persistent Identifiern (PIDs) unerlässlich geworden.
 Mit der wachsenden Bedeutung von PIDs im Forschungsalltag und zunehmend auch in kulturellen Kontexten, erhöhen sich aber auch die Anforderungen an das effiziente Zusammenspiel von PID-Systemen, um Nutzenden und ihre Informationssysteme bei der Anwendung von PIDs zu unterstützen.
 Im Vortrag werden die vielfältigen Einsatzmöglichkeiten von PIDs im Veröffentlichungsprozess von Open-Access-Publikationen näher beleuchtet. Besonderer Fokus wird dabei auf den „Digital Object Identifier“ (DOI) für die verlässliche und dauerhafte Auffindbarkeit von digitalen Forschungsobjekten, den Autor:innenidentifikator „ORCID“, die Gemeinsamen Normdatei (GND) und den Organisationsidentifikator „ROR“ gelegt. Erörtert wird welche Chancen und Herausforderungen der Einsatz von PIDs für Autor:innen und publizierende Einrichtungen im Kontext des Open-Access-Publizierens birgt. Im Konkreten wird beschrieben, an welchen Stellen im Open-Access-Publikationsworkflow wissenschaftlicher Einrichtungen, Bibliotheken und Publikationsinfrastrukturen in akademischer Trägerschaft PIDs mitgedacht und verwendet werden sollten. Hierbei wird neben den
 Einsatzmöglichkeiten in institutionellen Open-Access-Verlagen und -Repositorien auch die Verwendung von PIDs in Publikations- und Affiliationsrichtlinien thematisiert. Zudem wird darauf eingegangen, wie die Verbreitung von PIDs an einer Einrichtung unterstützt und Wissen zu PID-Systemen vermittelt werden kann, um das Zusammenspiel zwischen Menschen und Maschinen im Publikationsprozess zu erleichtern. Darüber hinaus werden aktuelle nationale (z. B. ORCID DE) und internationale Initiativen (z. B. Research Data Alliance, OpenAIRE) im Kontext von Open Science vorgestellt, die einen Beitrag zu einer vernetzte PID-Landschaft leisten und einen Rahmen für lokale PID-Anwendungen geben.

description: The applicability of standard methods for compositional analysis is limited for H-containing films. Neutron reflectometry is a powerful, non-destructive method that is especially suitable for these systems due to the large negative scattering length of H. In this work we demonstrate how neutron reflectometry can be used to investigate thin films of yttrium hydride. Neutron reflectometry gives a strong contrast between the film and the surface oxide layer, enabling us to estimate the oxide thickness and oxygen penetration depths. A surface oxide layer of 5-10 nm thickness was found for unprotected yttrium hydride films.

description: The advances in remote sensing technologies have boosted applications for Earth observation. These technologies provide multiple observations or views with different levels of information. They might contain static or temporary views with different levels of resolution, in addition to having different types and amounts of noise due to sensor calibration or deterioration. A great variety of deep learning models have been applied to fuse the information from these multiple views, known as deep multi-view or multi-modal fusion learning. However, the approaches in the literature vary greatly since different terminology is used to refer to similar concepts or different illustrations are given to similar techniques. This article gathers works on multi-view fusion for Earth observation by focusing on the common practices and approaches used in the literature. We summarize and structure insights from several different publications concentrating on unifying points and ideas. In this manuscript, we provide a harmonized terminology while at the same time mentioning the various alternative terms that are used in literature. The topics covered by the works reviewed focus on supervised learning with the use of neural network models. We hope this review, with a long list of recent references, can support future research and lead to a unified advance in the area.

description: Detection of high impedance faults (HIF) has been one of the biggest challenges in the power distribution network. The low current magnitude and diverse characteristics of HIFs make them difficult to be detected by over-current relays. Recently, data-driven methods based on machine learning models are gaining popularity in HIF detection due to their capability to learn complex patterns from data. Most machine learning-based detection methods adopt supervised learning techniques to distinguish HIFs from normal load conditions by performing classifications, which rely on a large amount of data collected during HIF. However, measurements of HIF are difficult to acquire in the real world. As a result, the reliability and generalization of the classification methods are limited when the load profiles and faults are not present in the training data. Consequently, this paper proposes an unsupervised HIF detection framework using the autoencoder and principal component analysis-based monitoring techniques. The proposed fault detection method detects the HIF by monitoring the changes in correlation structure within the current waveforms that are different from the normal loads. The performance of the proposed HIF detection method is tested using real data collected from a 4.16 kV distribution system and compared with results from a commercially available solution for HIF detection. The numerical results demonstrate that the proposed method outperforms the commercially available HIF detection technique while maintaining high security by not falsely detecting during load conditions.
