description: In this paper, we study certain critical Schrödinger-Kirchhoff type systems involving the fractional $p$-Laplace operator on a bounded domain. More precisely, using the properties of the associated functional energy on the Nehari manifold sets and exploiting the analysis of the fibering map, we establish the multiplicity of solutions for such systems.

description: In a recent Letter we proposed a means to realize a quasicrystal with eight-fold symmetry by trapping particles in an optical potential created by four lasers. The quasicrystals obtained in this way, which are closely related to the well-known octagonal tiling, offer unique possibilities to study the effects of quasiperiodicity on physical properties. This method allows to transform the structures, to inflate or deflate them, include interactions or disorder and thus realize a large variety of theoretical models, both classical and quantum. In this paper we derive a number of interesting geometrical properties of the optical quasicrystals, and present some results obtained by numerical calculations.

description: Mangrove forests provide a wealth of important ecosystem functions and services. They are highly productive and support biodiversity, serve as nurseries for fish and crustaceans, and provide coastal protection against storms and erosion. As a source of income for local fisher communities, they offer fish, crabs, shrimps, and mussels, raw materials for building, and medicinal resources. Rapid urbanization on Penang Island over the last few decades has caused the destruction and fragmentation of mangroves on the east coast. Along the western shorelines mangroves remain less fragmented. As coastal and offshore development is encroaching into fishing grounds, there are on-going conflicts between developers and fisher communities whose livelihoods depend on mangroves.

description: L’articolo offre un approfondimento sull’approccio dell’Unione Europea alla Riforma del Settore della Sicurezza (RSS), un concetto che in tempi recenti è diventato tema centrale delle agende di organizzazioni regionali e internazionali. Dopo una breve introduzione al concetto di SSR, l’analisi prende in considerazione l’evoluzione del quadro politico europeo: dai documenti del 2005 e 2006 sviluppati dal Consiglio e dalla Commissione, al più recente ‘Elementi di un quadro strategico dell'UE per sostenere la riforma del settore della sicurezza’ (2016). In seguito, l’articolo si focalizza sulle capacità istituite sia ai livelli centrali che sul campo per migliore il supporto dell’UE ai programmi di RSS nei paesi partner. Una lista degli strumenti, attori e strutture più rilevanti è fornita assieme ad una dettagliata descrizione dei loro ruoli e funzioni. Inoltre, le interviste condotte con funzionari del Servizio Europeo per l’Azione Esterna coinvolti nella RSS forniscono una chiara rappresentazione della capacità europea. Infine, l’ultimo paragrafo analizza l’approccio dell’UE da una prospettiva più concreta. La Repubblica della Georgia è scelta come caso studio per presentare le attività in atto e gli attori/strutture interessati nell’ambito dei programmi europei di RSS. Parole chiave: Unione Europea, Riforma del Settore della Sicurezza, Georgia, Politica, Attori The article provides an insight on the European Union’s approach to Security Sector Reform (SSR), a concept that in recent years has become a central issue on the agendas of regional and international organisations. After a brief introduction to the concept of SSR, the analysis takes in consideration the evolution of the EU policy framework: from the 2005 and 2006 documents developed by the Council and the Commission, to the most recent ‘Elements for an EU-wide strategic framework to support security sector reform’ (2016). Subsequently, it focuses on the capacities established both at the headquarters and in the field to improve EU’s support to SSR programmes in partner countries. A list of the most relevant instruments, actors and structures is offered along with a detailed description of their functions and roles. Furthermore, the interviews conducted with officials of the European External Action Service involved in SSR provide a clear overview of the EU capacity. Finally, the last paragraph analyses the EU’s approach from a closer perspective. The Republic of Georgia is chosen as a case study for presenting the activities in place and the actors/structures involved as part of the European SSR programmes.

description: We compute the next-to-next-to-leading order QCD corrections to the graviton production in models of TeV-scale gravity, within the soft-virtual approximation. For the Arkani-Hamed, Dimopoulos and Dvali (ADD) model we evaluate the contribution to the Drell-Yan cross section, and we present distributions for the di-lepton invariant mass at the LHC with a center-of-mass energy $\sqrt{s_H}=14\text{TeV}$. We find a large $K$ factor ($K\simeq 1.8$) for large values of invariant mass, which is the region where the ADD graviton contribution dominates the cross section. The increase in the cross section with respect to the previous order result is larger than $10\%$ in the same invariant mass region. We also observe a substantial reduction in the scale uncertainty. For the Randall-Sundrum (RS) model we computed the total single graviton production cross section at the LHC. We find an increase between $10\%$ and $13\%$ with respect to the next-to-leading order prediction, depending on the model parameters. We provide an analytic expression for the NNLO $K$ factor as a function of the lightest RS graviton mass.

description: Recent results in telecardiology show that compressed sensing (CS) is a promising tool to lower energy consumption in wireless body area networks for electrocardiogram (ECG) monitoring. However, the performance of current CS-based algorithms, in terms of compression rate and reconstruction quality of the ECG, still falls short of the performance attained by state-of-the-art wavelet based algorithms. In this paper, we propose to exploit the structure of the wavelet representation of the ECG signal to boost the performance of CS-based methods for compression and reconstruction of ECG signals. More precisely, we incorporate prior information about the wavelet dependencies across scales into the reconstruction algorithms and exploit the high fraction of common support of the wavelet coefficients of consecutive ECG segments. Experimental results utilizing the MIT-BIH Arrhythmia Database show that significant performance gains, in terms of compression rate and reconstruction quality, can be obtained by the proposed algorithms compared to current CS-based methods.

description: O aparecimento e reemergência de doenças infecciosas são continuamente documentados na história da humanidade com o delineamento de suas transmissões, sendo fortemente relacionados à globalização econômica, mudanças ambientais, demográficas e tecnológicas. Alguns agentes infecciosos causaram inúmeras mortes antes do seu desaparecimento; outros se tornaram endêmicos (epidemias periódicas) em uma população e, consequentemente, traçou um perfil de desigualdades, destacando regiões pobres e com precários sistemas de saúde. Patologias como a malária, cólera, esquistossomose, tuberculose, arbovírus de maneira geral (enfermidades transmitidas por vetores como mosquitos), problemas respiratórios, dentre outras, têm um impacto significativamente negativo na expectativa de vida da população, e afeta a economia de um país, uma vez que uma população doente tem sua força de trabalho reduzida. Neste cenário, a modelagem tem se tornado uma aliada, contribuindo para a compreensão das complexidades da transmissão e evolução dos patógenos, predição de tendências e seu controle. São modelos que se harmonizam aos contextos variados, capturam características individuais até um nível macro - levando em consideração características regionais, sociais e econômicas da população. Os resultados obtidos guiam áreas da epidemiologia e saúde pública no estudo da dinâmica de transmissão e controle de contágio de doenças infecciosas.

description: For miniaturization, as well as for improving artificial nanopore performance, precise local polymer functionalization and the combination of different functionalities are required. Imagining data driven nanopore design automated nanopore functionalization would be beneficial. Using direct laser writing as one option of automated nanopore polymer functionalization visible light induced polymerizations are beneficial. Here, we demonstrate the functionalization of mesoporous silicafilms with two different polymers using automated laser writing. For this we developed a visible light (400–700 nm and 405 nm) N,N(diethylamino)dithiocarbamoylbenzyl(trimethoxy)silane (SBDC) inifierter initiated polymerization. While transferring this visible light induced polymerization using SBDC to a commercially available microscope, direct, automated laser writing, as well as polymer re‐initiation was demonstrated. Thereby, polymer spots of 37 and 40 μm in diameter were achieved using 1–5 seconds for each irradiated spot.

Staff Complaint Reasons and Handling Mechanisms: Sebeta Town Administration Education Office in Focus, Oromia Regional State, Ethiopia

Year: 2023

description: The objective of this paper was to investigate the nature of staff complaints in Sebeta town education office. The study also assessed the reasons for complaints and examined ways of handling the complaints. In the research, case study research design was used. Data were collected through semi- structured interview guide from four team leaders, four staff members as well as three discipline committee members working in the education office. The respondents were selected purposefully. Based on the research findings, complaints in the office have emanated from the manner the organization is structured with regard to departments and human power, the way of doing things (stringency and unfairness), individual differences, and the challenges from the management. Though the management was open to deal with the complaints from the staff, some of the most common complaints by employees were low pay and benefits, unfair and frequently changing organizational structure, absences of promotion, and high work load. Most employees believe that their concerns cannot be solved at office level. Despite the availability of formal committee at office level to deal with grievance from the employees, nearly all complaints fail to pass through this formal channel.

description: Using a multi-epoch near-infrared spectroscopic dataset of three heavily-spotted T Tauri star systems we use empirical composite spectral models to constrain spot filling factors and temperatures. Empirical composite models are created through a weighted sum of two IRTF Spectral Library dwarf standard spectra, a cooler one for the spots and a hotter one for the photosphere, and then fit to each observed stellar spectra using a Markov-Chain Monte-Carlo algorithm. Fits to individual epochs reveal clear variations in filling factors that are correlated with photometric variability. Covering over one full stellar enables us to calculate the total spot coverage of the stars. Knowing this, we revise the HR diagram placement of our sample and obtain new mass and age estimates using traditional unspotted and new spotted evolutionary models. Our results suggest that a failure to account for spots results in mass and age spreads as large as a factor of two. Additionally, analysis of AAVSO photometric data reveals evidence for spot evolution on timescales as short as a few years.

This study tests the interaction between business and creative orientations of a founder in their influence on innovation in the context of creative entrepreneurial firms and provides recommendations for how creative agents can leverage and manage their innovations based on their creative visions. Determinants on the individual level, such as the founder's creative or business orientations, have a lasting impact on the practices and process of their venture. To trace the imprinting influence of the founder's orientation on innovation, the empirical setting is a time‐lagged study of German firm owners in the cultural and creative industries surveyed 5 years apart. The results show a significant relationship between creative orientation and innovation, whereas business orientation does not significantly relate to innovation. However, creative and business orientations reveal a negative interaction effect. This study contributes empirical evidence to the paradox theory and the interaction between the opposite poles. Our findings provide valuable insights about the relevance of creative orientation and its visionary impact on the firms' innovation process. Furthermore, the results shed new light on the tension between art and the market, as different compositions of the two orientation poles seem to have a varying impact on the degree of innovation. Thus, the study reveals the complexity of creative entrepreneurship and provides managerial guidance for other knowledge‐based industries.

description: In the paper we investigate integrability characteristics for the dispersionless Kadomtsev-Petviashvili hierarchy. These characteristics include symmetries, Hamiltonian structures and conserved quantities. We give a Lax triad to construct a master symmetry and a hierarchy of non-isospectral dispersionless Kadomtsev-Petviashvili flows. These non-isospectral flows, together with the known isospectral dispersionless Kadomtsev-Petviashvili flows, form a Lie algebra, which is used to derive two sets of symmetries for the isospectral dispersionless Kadomtsev-Petviashvili hierarchy. By means of the master symmetry, symmetries, Noether operator and conserved covariants, Hamiltonian structures are constructed for both isospectral and non-isospectral dispersionless Kadomtsev-Petviashvili hierarchies. Finally, two sets of conserved quantities and their Lie algebra are derived for the isospectral dispersionless Kadomtsev-Petviashvili hierarchy.

description: This article reports part of a research project that investigated the learning and social inclusion conditions of ‘newly arrived students’ in Swedish primary schools in two municipalities. Newly arrived students are the category of students who have lived abroad and started their education in Sweden when they were seven years old or older within the last four years. Most of these children and youth have a history of migration. This article focuses firstly on the Swedish migration context, the ‘migration crisis’ in 2015 and the changes in the Swedish reception system that took place soon thereafter and, second, ethnographic observations from Primary Schools of two specific perspectives in education, namely a perspective on ‘Framing of the day and the lesson’ and ‘Study tutoring in the mother tongue in regular teaching’. The results indicated that strong supporting structures and structured social interaction are needed as well as caring and empathy on the part of teachers to promote learning and social inclusion of newly arrived students are required. Furthermore, study tutoring in the mother tongue in regular teaching seems to be important while the study tutors’ view of their mission varies.

Exact Collapse Solutions in D=4, N=4 Gauged Supergravity and Their Generalizations

description: We construct an exact time-dependent solution in $D=4$, ${\cal N}=4$ gauged supergravity, where the gauge fields of the $U(1)\times U(1)$ subgroup of the $SO(4)$ carry independent conserved charges. The solution describes a decaying white hole that settles down to the final state as a static charged black hole. We analyze the global structure and lift the solution back to $D=11$ supergravity. We further extend the theory by adding an extra term in the scalar potential and obtain a more general class of collapse solutions. The result constitutes a charged generalization of the Roberts solution and the dynamical scalar-hairy black hole solutions that have been very recently found by us. The generalized Roberts solutions demonstrate that a scalar coupled to gravity can be unstable even when it is confined by a scalar potential with a fixed point.

E' certamente lecito affermare l'opinione che una tendenza all'empatia ci derivi, in quanto umani, dalla nostra evoluzione; ma sembra poco "scientifico" se non ne vengono fornite le evidenze; a meno di non considerare l' "evoluzionismo" una nuova "fede".

Robust comparison of multi-omics clustering algorithms for subtype discovery in chronic diseases

description: Multi-omics data is becoming increasingly available and there has been significant interest in using it to identify driving mechanisms and subtypes of chronic diseases. Unsupervised machine learning methods such as multi-view clustering analysis have been applied to partition patients based on their omics profiles. Often these methods are evaluated based on how accurately known partitions are recovered and how significant the survival differences between cancer patient subgroups are without accounting for relevant covariates, which is not ideal for discovering clinically actionable subtypes. In addition, the robustness to relatively small differences in the input data has not been considered. Here we have evaluated the stability of clustering results and metrics by resampling patients in publicly available omics datasets. In addition, we used linear models to account for covariates in survival analysis to better characterize the clinical relevance of clustering results. We compared popular multi-omics clustering approaches and considered recent kernel-based approaches that aim to integrate biological information in the form of functional pathways. Our analyses suggested that clustering results obtained from many methods were not reproducible on subsets of the data. Among the tested approaches, integrative non-negative matrix factorization (IntNMF) was particularly stable and yielded clinically relevant results.
Workshop: CESSDA Data Catalogue - What can be Done at the Catalogue End and What Needs Harmonized Metadata?

discoverability

description: CESSDA is the Consortium of European Social Science Data Archives. The CESSDA Data Catalogue provides metadata on research datasets in various languages, harvested from 20+ data repositories located in different countries. All use the same DDI metadata standard but it is not sufficient for a functional user interface (UI), harmonizing the metadata content itself is sometimes needed. For instance, country and data collection time filters in search interfaces rely on the machine-actionable codes in the metadata. The big question is: are there alternatives to this type of resource intensive metadata harmonization? Are there open source tools that would map all variants of country and other geographical names in a different language to the standardized codes, or different ways of documenting date information, and matching it with an ISO code? Social sciences would benefit from dialogue with other research domains relating to this. Another big issue is how to design the search interface so that users can navigate confidently between the language(s) of the metadata, the actual data files and the user interface where the languages may be the same or different? The CESSDA Catalogue team decided to reduce choice by providing the interface in English only but the metadata in different languages. According to our testing, multilingual search gave incomplete results in some languages. Are there open tools where the language analyzers are good enough to manage multilingual search across languages correctly? The aim of the workshop is to discuss possibilities for multilingual data catalogues and their user-facing interfaces in cases where there are no resource for AI enhancements; exchange information on useful tools and best practices; potential cooperation ideas. Posssible discussion items are: – Geographical location information GeoNames.org open source geographical database providing 27 million geographical names, matching country names in different languages to ISO codes and continents, administrative divisions etc. – EU Semantic Interoperability Catalogue – Search interface functionalities and language choices – Language analyzers

description: Divisibility of trinomials by given polynomials over finite fields has been studied and used to construct orthogonal arrays in recent literature. Dewar et al.\ (Des.\ Codes Cryptogr.\ 45:1-17, 2007) studied the division of trinomials by a given pentanomial over $\F_2$ to obtain the orthogonal arrays of strength at least 3, and finalized their paper with some open questions. One of these questions is concerned with generalizations to the polynomials with more than five terms. In this paper, we consider the divisibility of trinomials by a given maximum weight polynomial over $\F_2$ and apply the result to the construction of the orthogonal arrays of strength at least 3.

Analysis of gene regulatory properties underlying trait pleiotropy
Creators: name: González, Aitor
Publisher: name: F1000 Research Limited
Year: 2022

description: Genome-wide association studies (GWAS) have shown that pleiotropic genetic variants affecting multiple traits are relatively common in the genome. A large majority of these variants fall in non-coding regions and are likely gene regulatory variants. In this poster, we have computed the colocalization of 400 GWAS studies and 125 eQTL studies to pinpoint 9099 regulatory variants associated with GWAS traits. Regulatory variants belonging to more than one GWAS trait category have been defined as pleiotropic. We find that pleiotropic variants are clustered around a few pleiotropic genomic regions. Pleiotropic variants are also associated with more gene expression variation in more tissues and bind more transcription factors. In summary these analyses clarify the role of regulatory variants for trait pleiotropy.

description: The current rate of $.50 per hundredweight for drying and storing rough rice at commercial facilities in California produced insufficient revenues to encourage replacement or expansion of existing facilities at current cost levels. Analyses of capital requirements and operating costs, using economic-engineering techniques, show that per hundredweight operating costs, when annual receipts equal storage capacities, are higher than expected revenues for all 11 model plants developed in this study. Models consist of four sizes—100,000, 300,000, 600,000, and 900,000 hundredweight storage capacity--and three types of operations--all upright storage, 60-percent flat storage, and 80-percent flat storage, with high-capacity aeration to aid drying--in varying combinations. Estimated operating costs range from $.52 to $1.50 per hundredweight of rough rice received at 100-percent annual receipt levels. Costs favor the use of flat storage with high-capacity aeration by as much as 22 percent in the larger models. In operations of like type, costs per hundredweight were over 50 percent lower in the largest plant size than the smallest size. Capital requirements ranged from $750,000 to $3.25 million. Diseconomies resulting from reduced rates of plant utilization more than overshadowed economies of size.

Subjects: subject: Algebraic Geometry (math.AG)

description: Consider a singular curve $Γ$ contained in a smooth 3-fold $X$. Assuming the general elephant conjecture, the general hypersurface section $Γ\subset S\subset X$ is Du Val. Under that assumption, this paper describes the construction of a divisorial extraction from $Γ$ by Kustin--Miller unprojection. Terminal extractions from $Γ\subset X$ are proved not to exist if $S$ is of type $D_{2k}, E_7$ or $E_8$ and are classified if $S$ is of type $A_1,A_2$ or $E_6$. The $A_n$ and $D_{2k+1}$ cases shall be considered in a further paper.

description: Describing bacterial phenotypes is an essential component to identify bacterial species and studying biodiversity and evolution. The large-scale integration and analysis of full phenotypic traits of an organism, can enrich existing data and provide novel scientific insights. The lack of tools for efficiently and accurately extracting information in a structured manner can be attributed to heterogeneity and fragmentation of the data sources, variable standards, and limited interoperability of the data. The project Digital Approaches for the Synthesis of Poorly Accessible Biodiversity Information (DiASPora) aims to establish an automated pipeline for the extraction of phenotypic characters from published literature by application of Natural Language Processing and AI models. In this poster, we describe our progress on the development of the web server for automating data curation and thereby enriching the information available in the database for standardized bacterial information ‘BacDive’.
