Planetesimal Dynamics in the Presence of a Giant Planet. II. Dependence on Planet Mass and Eccentricity
Authors: Guo Kangrou , Kokubo Eiichiro
Published: August 2022

The presence of an early-formed giant planet in the protoplanetary disk has mixed influence on the growth of other planetary embryos. Gravitational perturbation from the planet can increase the relative velocities of planetesimals at the mean motion resonances to very high values and impede accretion at those locations. However, gas drag can also align the orbital pericenters of equal-size planetesimals in certain disk locations and make them dynamically quiet and “accretion-friendly” locations for planetesimals of similar sizes. Following the previous paper, where we investigated the effect of a Jupiter-like planet on an external planetesimal disk, we generalize our findings to extrasolar planetary systems by varying the planet parameters. In particular, we focus on the dependence of the planetesimal relative velocities on the mass and eccentricity of the existing planet. We found that the velocity dispersion of identical-mass particles increases monotonically with increasing planet mass. Meanwhile, the dependence of the relative velocity between different-mass planetesimals on their mass ratio becomes weaker as the planet mass increases. While the relative velocities generally increase with increasing planet eccentricity, the velocity dispersion of lower-mass particles (m ≲ 1018 g) is almost independent of planet eccentricity owing to their strong coupling to gas. We find that the erosion limits are met for a wider range of parameters (planet mass/eccentricity, planetesimal mass ratio) when the planetesimal size decreases. Our results could provide some clues for the formation of Saturn’s core, as well as the architecture of some exoplanetary systems with multiple cold giant planets.

Published: August 2022

Synchrotron X-ray emission in young supernova remnants (SNRs) is a powerful diagnostic tool to study the population of high-energy electrons accelerated at the shock front and the acceleration process. We performed a spatially resolved spectral analysis of NuSTAR and XMM-Newton observations of the young Kepler’s SNR, aiming to study in detail its nonthermal emission in hard X-rays. We selected a set of regions all around the rim of the shell and extracted the corresponding spectra. The spectra were analyzed by adopting a model of synchrotron radiation in the loss-limited regime, to constrain the dependence of the cutoff energy of the synchrotron radiation on the shock velocity. We identify two different regimes of particle acceleration, characterized by different Bohm factors. In the north, where the shock interacts with a dense circumstellar medium (CSM), we found a more efficient acceleration than in the south, where the shock velocity is higher and there are no signs of shock interaction with the dense CSM. Our results suggest an enhanced efficiency of the acceleration process in regions where the shock–CSM interaction generates an amplified and turbulent magnetic field. By combining hard X-ray spectra with radio and γ-ray observations of Kepler’s SNR, we modeled the spectral energy distribution. In the light of our results we propose that the observed γ-ray emission is mainly hadronic and originates in the northern part of the shell.
Properties of the Lowest-metallicity Galaxies over the Redshift Range z = 0.2 to z = 1

Published: August 2022

Low-metallicity galaxies may provide key insights into the evolutionary history of galaxies. Galaxies with strong emission lines and high equivalent widths (rest-frame EW(Hβ) ≳ 30 Å) are ideal candidates for the lowest-metallicity galaxies to z ∼ 1. Using a Keck/DEIMOS spectral database of about 18,000 galaxies between z = 0.2 and z = 1, we search for such extreme emission-line galaxies with the goal of determining their metallicities. Using the robust direct T

e
method, we identify eight new extremely metal-poor galaxies (XMPGs) with

O/H ≤7.65, including one at 6.949 ± 0.091, making it the lowest-metallicity galaxy reported to date at these redshifts. We also improve upon the metallicities for two other XMPGs from previous work. We investigate the evolution of Hβ using both instantaneous and continuous starburst models, finding that XMPGs are best characterized by continuous starburst models. Finally, we study the dependence on age of the buildup of metals and the emission-line strength.
A New Method of Fluxgate Magnetometer Offset Vector Determination in the Solar Wind Using Any Magnetic Field Variations
Authors: Wang Guoqiang
Published: August 2022

In-depth study of dynamic processes in the astrophysical plasma environment relies on high-precision measurement of the magnetic field. Fluxgate magnetometers (FGMs) are commonly used on spacecraft to measure the magnetic field. However, their zero offsets vary slowly with time, and therefore need regularly in-flight calibration. Traditional methods of calculating the zero offset are based on properties of Alfvén waves, mirror mode structures, or current sheets. Here, we develop a new method of calculating the zero offset using any interplanetary magnetic field (IMF) variations. We create an offset cube according to the possible range of the IMF strength. The average values of B
L for the IMF variation events approximately obey the normal distribution if there are enough events, where B
L is the magnetic field in the maximum variance direction. Any constant vector added to the natural magnetic field data of the events will make the standard deviation of the normal distribution larger. Thereby, the point is determined to be the zero offset so that the corresponding standard deviation at this point is the minimum in the offset cube. Our test results show that this method has a 95.5% probability of obtaining the zero offset with an error of less than 0.3 nT when 10–21 hr of data are used. Our method provides an option for the in-flight calibration of the spaceborne FGM in the solar wind when there are not enough Alfvén waves, mirror modes, or current sheets.

Authors: Soeroso Noni Novisari , Panggabean Freddy , Tarigan Setia Putra , Zaluchu Fotarisman , Ananda Fannie Rizki
Published: August 2022

Background: Bisphosphonates (BPs) are commonly used as supportive therapy to prevent skeletal-related events in lung cancer patients with bone metastasis, including severe bone pain, hypercalcemia, and pathological fractures. The purpose of this study was to assess the effectiveness of bisphosphonate therapy to reduce pain in non-small cell lung cancer (NSCLC) patients with bone metastasis. 
Methods: This was a cross-sectional study carried on 38 patients diagnosed with lung cancer based on cytology or histopathology findings. Radiological examination such as thoracic CT scan, bone survey, and bone scan was performed to determine bone metastasis. Multimodality therapy is carried out for lung cancer palliative therapy including chemotherapy, radiotherapy, and bisphosphonate therapy (zoledronic acid and ibandronate) as supportive therapy to reducing cancer pain. Pain was assessed using the Visual Analog Scale (VAS) determined by patients themselves. Statistical tests were performed by paired T-test in which p< 0.05 was considered significant. 
Results: As many as 38 patients enrolled in this study consisting of 29 men (76.3%) and 9 women (23.7%). The subtype of adenocarcinoma was mostly found in 31 cases (81.58%) and 7 cases (18.42%) was Squamous Cell Carcinoma. Cancer pain was found in all patients. Measurement of pain prior to treatment showed that most patients had VAS level of 7-10. After bisphosphonate therapy, the VAS level significantly decreased to 1-3 (p<0.01). 
Conclusion: Bisphosphonate therapy was proven to effectively decrease the severity level of cancer pain in lung cancer patients with bone metastasis.
Rate of Epstein-Barr Virus in Gastric Adenocarcinoma in Egyptian Patients in View of the WHO Classification and Correlation with p16 Immunoreactivity
Authors: Samir Safia , Ahmed Hend Okasha , Diab Tarek M. , Mostafa Amr , Elmeligy Hesham A. , Kamel Amira , Khalil Heba
Published: August 2022

BACKGROUND AND AIM: Gastric cancer (GC) is one of the top causes of cancer-related deaths worldwide. According to the Cancer Genome Atlas, there are four subtypes of GC, with the Epstein-Barr virus (EBV) subtype accounting for about 10% of cases. EBV infection causes EBV-associated GC (EBVaGC). The previous research suggested that the presence of the EBV viral genome in gastric carcinomas could be used as a surrogate marker for targeted therapy and optimal GC treatment.

AIM: We aimed to explore the rate of EBV involvement in gastric carcinogenesis from molecular perspective view and to evaluate the role of the tumor-suppressor protein p16 as a marker for diagnosis in GC Egyptian patients in relation to EBV infection.

METHODS: One hundred-four surgically resected GC cases were analyzed. Two methods including quantitative real-time polymerase chain reaction (qPCR) for detecting EBV-derived latent membrane protein-1 (LMP-1) and Epstein-Barr nuclear antigen-1 (EBNA-1) genes as well as immunohistochemistry (IHC) detection of LMP-1 protein and p16 protein on paraffinized tissue blocks were applied.

RESULTS: Using IHC, p16 protein was presented in 90/104 (86.5%) of the GC cases, and EBV LMP-1 was detected in 4 cases (3.84%). qPCR detected 14 cases positive for EBV (13.46%). In EBV positive cases detected using qPCR, no expression of p16 was detected.

CONCLUSION: EBVaGC has a low incidence in Egypt; loss of p16 expression was recognized in EBVaGC and could be considered as a promising biomarker of EBVaGC. The combination of the two methods IHC and qPCR in addition to p16 is recommended for improving the accuracy of identification of infected cancer.
Demonstration of the New IPNI (International Plant Names Index) Registration System
Authors: Wrankmore Emma , Krieger Jonathan , Govaerts Rafaël , Hartley Helen
Published: August 2022

Registration systems have long been in place for names of plant cultivars, fungi, prokaryotes and animals, and more recently for algae (Müller et al. 2022). Yet, despite previous attempts, nothing has become established for vascular plants. The newly released International Plant Names Index (IPNI) registration system aims to address this. We will be demonstrating that this new system can be used to register vascular plant names that are new to science, in addition to names that have been validly published but are not yet in IPNI (The Royal Botanic Gardens, Kew et al. 2022). We will show the different options that are available and explain how we validate the data and ensure its integrity. The demonstration will also focus on the standards we use, and how these are maintained.

The new registration system will allow resources to be used more efficiently and give scientists more control over how and when the names they publish are entered into IPNI and made available for users worldwide. Without registration, indexers must manually check scientific publications from around the world (both hard copy and online) to find newly published names. Registration will release time for indexers to spend on improving data quality, resolving nomenclatural issues, adding missing names, and ensuring IPNI complies with existing and future data standards. The current project is working to ensure that the registration system has a wide uptake to maximise these benefits.
Bootstrapping a Biodiversity Knowledge Graph
Authors: Page Roderic
Published: August 2022

The "biodiversity knowledge graph" is a nice metaphor for connecting biodiversity data sources, but can we actually build it? Do we have sufficient linked data available? Given that a knowledge graph is an aggregation of data from multiple sources, how do we give those sources credit for that data, and how do we handle changes to that data? Given that the classic interface to a knowledge graph is an intimidatingly empty SPARQL query box, how do we make the knowledge within a graph more accessible?

This talk discusses an attempt to build a knowledge graph with an eye on how to maintain the graph in the future. It adopts a model similar to Global Biodiversity Information Facility (GBIF) and CheckListBank where individual data providers make datasets available as independently citable units with Digital Object Identifiers (DOIs). Each dataset comprises linked data in the form of N-triples. To create a knowledge graph we simply download one or more such datasets and add them to a triple store. Each data source is assigned to its own named graph, such that we have provenance for each dataset, and we can update any dataset independently. Furthermore, anyone can build their own knowledge graph by mixing and matching the set of data (people, publications, taxa, etc.) most appropriate to their interests.

To bootstrap this approach, exemplar datasets are created based on data harvested from ORCID, Zenodo, and taxonomic name databases. Each demonstration dataset could be replaced in the future by data published directly by those providers. In some cases there are sufficient shared identifiers (such as DOIs and ORCIDs) to form a graph, but taxonomic data typically forms isolated islands. To help the knowledge graph coalesce we need "glue" in the form of datasets that link pairs of different identifiers, such as Life Science Identifiers (LSIDs) for names to DOIs for publications. With the addition of those cross links we can start to generate bibliographies for taxa, discover communities of taxonomic expertise, and more. This model of building a knowledge graph also opens opportunities for smaller, focussed datasets to be added to the graph using the same approach (as set of N-triples archived in an online repository).

In order to be useful, a knowledge graph needs to be easy to query and visualise. Simply providing a SPARQL endpoint is unlikely to be enough. As part of this project, I developed a GraphQL interface to the knowledge graph to provide a set of standard queries that can support a simple web interface to the graph. This provides a way to explore the graph as it is being developed, which in turn can highlight gaps in connectivity and coverage that need to be addressed.

Published: August 2022

During the recent decade, high-throughput sequencing (HTS) techniques, in particular, DNA metabarcoding, have facilitated increased detection of biodiversity, including harmful algal bloom (HAB) species. In this study, the presence of HAB species and their appearance patterns were investigated by employing molecular and light microscopy-based monitoring in Tokyo Bay, Japan. The potential co-appearance patterns between the HAB species, as well as with other eukaryotes and prokaryotes were investigated using correlation and association rule-based time-series analysis. In total, 40 unique HAB species were detected, including 12 toxin-producing HAB species previously not reported from the area. More than half of the HAB species were present throughout the sampling season (summer to autumn) and no structuring or succession patterns associated with the environmental conditions could be detected. Statistically significant (p < 0.05, rS ranging from −0.88 to 0.90) associations were found amongst the HAB species and other eukaryotic and prokaryotic species, including genera containing growth-limiting bacteria. However, significant correlations between species differed amongst the years, indicating that variability in environmental conditions between the years may have a stronger influence on the microalgal community structure and interspecies interactions than the variability during the sampling season. The association rule-based time-series analysis allowed the detection of a previously reported negative relationship between Synechococcus sp. and Skeletonema sp. in nature. Overall, the results support the applicability of metabarcoding and HTS-based microalgae monitoring, as it facilitates more precise species identification compared to light microscopy, as well as provides input for investigating potential interactions amongst different species/groups through simultaneous detection of multiple species/genera.
New studies on Apiospora (Amphisphaeriales, Apiosporaceae): epitypification of Sphaeria apiospora, proposal of Ap. marianiae sp. nov. and description of the asexual morph of Ap. sichuanensis
Authors: Pintos Ángel , Alvarado Pablo
Published: August 2022

In the present work, an epitype for Sphaeria apiospora, the basionym of the type species of the genus Apiospora, Apiospora montagnei, is selected among collections growing in the host plant species reported in the original protologue, Arundo micrantha. Most samples obtained from localities near that of the lectotype (Perpignan, France) belong to the same species, which is not significantly different from the clade previously named Ap. phragmitis, suggesting that this name is a later synonym of Ap. montagnei. In addition, the name Ap. marianiae is here proposed to accommodate a newly discovered species found in the Balearic Islands (Spain), and the asexual state of Ap. sichuanensis is described for the first time from samples growing in the same islands.
Mezcala – a new segregate genus of mimosoid legume (Leguminosae, Caesalpinioideae, mimosoid clade) narrowly endemic to the Balsas Depression in Mexico
Authors: Hughes Colin E. , Ringelberg Jens J. , Luckow Melissa , Jiménez José Luis Contreras
Published: August 2022

Recent results have demonstrated that the genus Desmanthus is non-monophyletic because the genus Kanaloa is nested within it, with a single species, Desmanthus balsensis placed as sister to the clade comprising Kanaloa plus the remaining species of Desmanthus. Here we transfer D. balsensis to a new segregate genus Mezcala, discuss the morphological features supporting this new genus, present a key to distinguish Mezcala from closely related genera in the Leucaena subclade, and provide a distribution map of M. balsensis.
Phylogenomic assessment prompts recognition of the Serianthes clade and confirms the monophyly of Serianthes and its relationship with Falcataria and Wallaceodendron in the wider ingoid clade (Leguminosae, Caesalpinioideae)

Published: August 2022

The Indo-Pacific legume genus Serianthes was recently placed in the Archidendron clade (sensu Koenen et al. 2020), a subclade of the mimosoid clade in subfamily Caesalpinioideae, which also includes Acacia, Archidendron, Archidendropsis, Falcataria, Pararchidendron, Paraserianthes and Wallaceodendron. Serianthes comprises ca. 18 species, five subspecies and two varieties that are characterised by bipinnately compound leaves with alternate sessile leaflets, branched axillary corymbiform panicles and woody indehiscent pods. Generic relationships, as well as species relationships within genera in the Archidendron clade, remain uncertain. While the sister relationship between Serianthes and the genus Falcataria is strongly supported by molecular data, the distinction between Serianthes and the monotypic genus Wallaceodendron has been questioned, based on their similar flower and fruit morphologies. We combined three gene-enriched hybrid capture DNA sequence datasets (generated from the 964 mimobaits v1 probe set, the expanded 997 mimobaits v2 probe set and the GoFlag angiosperm 408 probe set) and used their overlapping markers (77 loci of the target exonic and flanking regions) to test the monophyly of Serianthes and to investigate generic relationships within the Archidendron clade using 55 ingoid plus two outgroup taxa. We show that Serianthes is monophyletic, confirm the Serianthes + Falcataria sister relationship to Wallaceodendron and recognise this combined clade as the Serianthes clade within the Archidendron clade. We also evaluated the use of overlapping loci across datasets in combination with concordance analyses to test generic relationships and further investigate previously unresolved relationships across the wider ingoid clade. Concordance analysis revealed limited gene tree conflicts near the tips of the Archidendron clade, but increased discordance at the base of the clade, which could be attributed to rapid lineage divergence (radiation) and/or incomplete lineage sorting.

Phylogenetic analyses of DNA sequence data sampling all species of Leucochloron alongside representatives of genera of the Inga and Albizia clades of the larger ingoid clade of mimosoid legumes (sensu Koenen et al. 2020) confirm the non-monophyly of the genus Leucochloron. We show that Leucochloron bolivianum is placed in the Albizia clade, while the remaining four species of Leucochloron are placed in the Inga clade, in line with previous results. To rectify this non-monophyly, L. bolivianum is segregated as the new genus, Boliviadendron, with a single species, Boliviadendron bolivianum, narrowly endemic to the interior Andean valleys of Bolivia. We illustrate this new segregate genus, present a map of its distribution and discuss the striking lack of morphological distinctions between Boliviadendron and Leucochloron, as well as the phylogenetic and morphological affinities of Boliviadendron to the genera Enterolobium and Albizia.
Revisiting the phylogeny and taxonomy of the Pithecellobium clade (Leguminosae, Caesalpinioideae) with new generic circumscriptions

Published: August 2022

We present the most complete molecular phylogeny to date of the Pithecellobium clade of subfamily Caesalpinioideae. This neotropical group was informally recognised (as the Pithecellobium alliance) at the end of the 20th century by Barneby and Grimes (1996) and includes five genera and 33 species distributed from the southern United States and Caribbean Islands to north-eastern South America. Our aims were to further test the monophyly of the group and its genera and to identify sister group relationships within and amongst the genera. A phylogenetic analysis of nuclear ribosomal DNA sequences (ITS and ETS) was performed. The results provide further support for the monophyly of the Pithecellobium clade. The genera Ebenopsis, Pithecellobium and Sphinga were strongly supported as monophyletic. Havardia and Painteria were found to be non-monophyletic, prompting their re-circumscriptions and the description of two new genera: Gretheria and Ricoa. New combinations are made for the three species transferred to the new genera.
A new generic circumscription of Hydrochorea (Leguminosae, Caesalpinioideae, mimosoid clade) with an amphi-Atlantic distribution

Published: August 2022

Hydrochorea and Balizia were established to accommodate four and three species, respectively, that were previously included in different ingoid genera, based primarily on differences in fruit morphology. Both genera have Amazonia as their centre of diversity, extending to Central America and the Brazilian Atlantic Rainforest. Previous phylogenetic evidence showed Balizia to be paraphyletic with respect to Hydrochorea, and species of Hydrochorea and Balizia were placed in a large unresolved polytomy with species of Jupunba. Here we present a new phylogenomic analysis based on 560 exons, from which 686 orthologous alignments were derived for gene tree inference. This analysis confirms a paraphyletic Balizia in relation to Hydrochorea, together with two African species formerly placed in Albizia nested within the clade. Jupunba macradenia was resolved as sister to the clade combining those taxa. However, quartet support is low for several of the branches at the base of the clade combining the genera Jupunba, Balizia and Hydrochorea, suggesting that rapid initial divergence in this group led to extensive incomplete lineage sorting and consequently poor phylogenetic resolution. Because of these phylogenomic complexities, we decided to use morphology as the main guide to consider Hydrochorea as a distinct genus from Jupunba, and Balizia as a new synonym for Hydrochorea. The taxonomic treatment includes the study of collections from various herbaria and fieldwork expeditions. We present a re-circumscribed Hydrochorea accommodating a total of 10 species, including six new combinations, five new synonyms, one new taxonomic status, two corrections of nomenclature category for lectotypes, and a second step lectotype and three new lectotypes. A new species from the Brazilian Amazon is described and illustrated. An identification key for all species of Hydrochorea is presented, together with comments and illustrations.
A survey on temporal network dynamics with incomplete data
Authors: Wu Xing , Mao Shuai , Xiong Luolin , Tang Yang
Published: August 2022

With the development of complex network theory, many phenomena on complex networks, such as infectious disease transmission, information spreading and transportation management, can be explained by temporal network dynamics, to reveal the evolution of the real world. Due to the failure of equipment for collecting data, human subjectivity, and false decisions made by machines when the high accuracy is required, data from temporal networks is usually incomplete, which makes the samples unrepresentative and the model analysis more challenging. This survey concentrates on the pre-processing strategies of incomplete data and overviews two categories of methods on data imputation and prediction, respectively. According to whether each layer in temporal networks has the coupling process, this survey overviews the dynamic modeling approaches in terms of both a single process and coupling processes on complex temporal networks. Moreover, for complex temporal networks with incomplete data, this survey summarizes various characteristic analysis methods, which concentrate on critical nodes identification, network reconstruction, network recoverity, and criticality. Finally, some future directions are discussed for temporal networks dynamics with incomplete data.
The supervision and regulation of climate risks for banks: overview from the perspective of a European practitioner
Authors: Hess Patrick
Published: August 2022

Climate change is one of the most pressing issues of our time, and in the transition to a greener and more environmentally sustainable economy and financial system, banks and their supervisors and regulators play a key role. By giving preference to climate-friendly borrowers and green assets in their financing and investment decisions, banks have a huge leverage over economic actors and financial market participants, and thus can help the transition to a greener economy. At the same time, banks must assess and manage the physical and transition risks that emanate from climate change and impact their clients via various transmission channels, thereby affecting the banks themselves. This risk dimension is the focus of this paper. Based on the euro area perspective it answers from a mainly practical perspective the question whether voluntary action by banks is sufficient, or whether additional regulatory requirements and respective supervisory scrutiny are necessary to cope with climate and environmental risks. Furthermore, the paper assesses whether such regulatory requirements should generally be of a qualitative, or also of a quantitative nature, and also the likelihood that regulators will going forward amend the rulebook to allow supervisors to impose direct capital requirements on banks for climate-related risks.
CED-Net: A more effective DenseNet model with channel enhancement
Authors: Li Xiangqun , Chen Hu , Zheng Dong , Xu Xinzheng
Published: August 2022

In recent years, deep convolutional neural network (CNN) has been applied more and more increasingly used in computer vision, natural language processing and other fields. At the same time, low-power platforms have more and more significant requirements for the size of the network. This paper proposed CED-Net (Channel enhancement DenseNet), a more efficient densely connected network. It combined the bottleneck layer with learned group convolution and channel enhancement module. The bottleneck layer with learned group convolution could effectively increase the network's accuracy without too many extra parameters and computation (FLOPs, Floating Point Operations). The channel enhancement module improved the representation of the network by increasing the interdependency between convolutional feature channels. CED-Net is designed regarding CondenseNet's structure, and our experiments show that the CED-Net is more effective than CondenseNet and other advanced lightweight CNNs. Accuracy on the CIFAR-10 dataset and CIFAR-100 dataset is 0.4 and 1% higher than that on CondenseNet, respectively, but they have almost the same number of parameters and FLOPs. Finally, the ablation experiment proves the effectiveness of the bottleneck layer used in CED-Net.
An Iranian Videogame Industry? Localizing Videogame Production Beyond The “Global” Videogame Industry
Authors: Daiiani Mahsuum , Keogh Brendan
Published: August 2022

Videogame researchers have long considered the role videogames play in different cultural, social, and political contexts around the world. However, when it comes to researching videogame production, literature on the nominally global videogame industry has primarily focused on the dominant sites of North America, Western Europe, and East Asia. In this article, we argue that entrenched conceptualizations of the global videogame industry risk applying Westerncentric models of success and growth that fail to account for how videogame industries emerge from the interplay of global distribution and local conditions. We contribute to a growing body of scholarship that strives to localize videogame production cultures through an analysis of how Iranian videogame developers navigate local cultural, economic, and regulatory contexts alongside global markets, platforms, and genres. By outlining the formative ambivalence with which Iranian developers engage both with and against the “global” videogame industry, we demonstrate the importance of accounting for different local (and translocal) videogame production cultures mediated by global enterprise.
Les socialistes et la ville
Authors: Moret Frédéric
Published: August 2022

L’acuité de la crise urbaine dans la première moitié du XIXe siècle est à l’origine d’une large réflexion émanant des classes dirigeantes contemporaines. À côté des universitaires, des philanthropes, des hygienistes, les socialistes britanniques et français se sont penchés sur les effets sociaux de l’industrialisation dressant un portrait sans complaisance de la société urbaine de ce temps. Leur analyse du fait urbain, qui reprend les discours contemporains, est au cœur de l’élaboration de leurs différents systèmes sociaux. Ils se fixent pour objectif de résoudre et de dépasser les contradictions d’un monde qui leur paraît – dans une période qui pourtant est celle de l’émergence de la société industrielle – se situer au crépuscule de son existence.
La ville, symptôme de dérèglement, est ainsi présentée comme le repoussoir, l’antithèse du modèle harmonieux que construisent Fourier en France, Owen et ses disciples en Grande-Bretagne. Le « village of Unity and Mutual Cooperation » et le phalanstère se situent en milieu rural, à l’écart de toute agglomération. Pourtant, leur forme et leurs fonctions sont marquées de références urbaines. Progressivement, dans les milieux socialistes français, la contradiction entre un discours résolument anti-urbain et la réalité sociale et culturelle des individus et des groupes influencés par ces idées constitue un frein au développement du mouvement. La fuite de la ville, la résolution du problème social par la construction ex nihilo d’une société nouvelle – qu’il est facile de qualifier d’utopiste – ne satisfont plus des socialistes qui réinvestissent la ville de leur désir et de leur projet. Cette prise en compte du fait urbain s’accompagne d’une attention nouvelle au politique, mais aussi à l’histoire, et conduit le mouvement fouriériste, conduit par Victor Considerant après la mort du fondateur, à intégrer les rangs de la gauche républicaine en 1848. Son sort sera lié à celui de la Montagne. Au contraire, le refus d’une évolution semblable chez Owen aboutit à une sclérose du mouvement et à sa progressive perte d’influence.
Topic Detection and Tracking Towards Determining Public Agenda Items
Authors: Komecoglu Basak Buluz , Yilmaz Burcu
Published: August 2022

It is a known fact that all of the events that people in the society are exposed to while continuing their lives have important effects on their quality of life. Events that have significant effects on a large part of the society are shared with the public through news texts. With a perspective that keeps up with the digital age, the problem of automatic detection and tracking of events in the news with natural language processing methods is discussed. An event-based news clustering approach is presented for data regimentation, which is necessary to extract meaningful information from news in the form of heaps in online environments. In this approach, it is aimed to increase clustering performance and speed by making use of named entities. Additionally, an event-based text clustering dataset was created by the researchers and brought to the literature. By using the B-cubed evaluation metric on this test dataset, which consists of 930 different event groups and has a total of 19,848 news, a solution to the event-based text clustering problem was provided with an F-score of over 85%.

Therefore, the components that teachers can apply to prevent peer bullying, education programs, classroom environments, and what needs to be done at the individual level, will be explained with sub-titles. Some suggestions will be made to help teachers support peer relationships.
Premature ventricular contraction recognition using blind source separation and ensemble gaussian naive bayes weighted by analytic hierarchy process
Authors: Oliveira Bruno Rodrigues de , Duarte Marco Aparecido Queiroz , Vieira Filho Jozue
Published: August 2022

Premature Ventricular Contractions (PVC) arrhythmias can be associated with sudden death and acute myocardial infarction, occurring in 50% of the population for Holter monitoring. PVC patterns are very hard to be recognized since their waveforms can be confused with other heartbeats, such as Right and Left Bundle Branch Blocks. This work proposes a new approach for PVC recognition, based on Gaussian Naive Bayes algorithm and AMUSE (Algorithm for Multiple Unknown Signal Extraction), which is a method for the blind source separation problem. This approach provides a set of attributes that are combined by Linear Discriminant Analysis, allowing the training of an ensemble learning. The Analytic Hierarchy Process weights each learned model according to its importance, obtained from the performance metrics. This approach has some advantages over baseline methods since it does not use a pre-processing stage and employs a simple machine learning model trained using only two parameters for each feature. Using a standard dataset for training and test phases, the proposed approach achieves 98.75% accuracy, 90.65% sensitivity, and 99.46% specificity. The best performance was 99.57% accuracy, 98.64% sensitivity, and 99.65% specificity for other datasets. In general, the proposed approach is better than 66% of the state-of-the-art methods concerning accuracy
Zonas limítrofes religiosas en el ritual mortuorio de evangélicos Aymara rurales en la región Arica y Parinacota de Chile
Authors: Slootweg Johanna Corrine
Published: August 2022

El objetivo de este artículo es presentar un análisis acerca de zonas limítrofes religiosas y cómo estas se perciben en sujetos aymara evangélicos rurales de la Región de Arica y Parinacota de Chile en las celebraciones de rituales mortuorios tradicionales aymara católicos. Se enfatizan los derechos de la autodeterminación religiosa de acuerdo con los conceptos de Girardi y de Fornet-Betancourt. Estos facilitan las prácticas de las zonas limítrofes religiosas y las posibilidades de la negociación simbólica, en concordancia con las ideas de Calisaya referente a las prácticas rituales a nivel familiar y comunitario. Fue empleada una metodología de estudio de caso colectivo con técnicas de entrevistas en profundidad, investigación de fuentes secundarias y participación observante dirigida. Los resultados dan cuenta de la solidaridad y el respeto a las tradiciones ancestrales, oponiéndose a visiones que acentúan la violencia interna que se produce en las comunidades rurales entre grupos aymara católicos tradicionales y evangélicos.Palabras clave: zonas limítrofes religiosas, autodeterminación religiosa, negociación simbólica, solidaridad familiar, tradiciones ancestrales aymaras.
“Y el Verbo se hizo carne y habitó entre nosotros” - la transnacionalización sur-sur del pentecostalismo brasileño: la UCKG y el proyecto de la Angola moderna

Este artículo se centró en la conexión transnacional Sur-Sur del pentecostalismo brasileño en Angola, centrándose en representaciones y perspectivas orientadas a la modernización. Se sostiene, por tanto, que la Iglesia Universal del Reino de Dios se inserta en Angola como un agente modernizador responsable de reformas culturales, cuyo objetivo es readaptar a los individuos a la nueva estructura política liberal. Su proselitismo acaba por desmantelar las identidades estables del pasado, centrándose en el surgimiento de una concepción más individualista del sujeto, para afrontar la dinámica económica del capitalismo contemporáneo. Usaremos la idea de una “máquina de resonancia” de Willian Connolly (2005), en la que la cara pública de la UCKG en Angola se constituye en su interfaz con las políticas estatales, los problemas sociales, los acuerdos culturales locales y las regulaciones legales nacionales. Nos interesan particularmente las interacciones entre las prácticas discursivas del IURD y las políticas liberalizadoras estatales, tanto en el discurso público de la Iglesia como en la construcción de sujetos y subjetividades vinculados al neoliberalismo, en lo que Foucault (2008) llamó “autoemprendimiento”. Así, nuestros análisis se benefician del trabajo de campo realizado en la ciudad de Luanda, capital de Angola, entre 2016 y 2018, en el que buscamos analizar los discursos que sustentan la estructura narrativa iurdiana.
The global financial crisis and the speed of capital structure adjustment: Evidence from South Africa
Authors: Moyo Vusani , Markou Demetris
Published: August 2022

Orientation: The 2007–2008 global financial crisis (GFC) represented a negative economic shock that financially constrained most firms globally.Research purpose: This study investigated the impact of the 2007–2008 GFC on firms’ speed of adjustment (SOA) towards target leverage and whether this is a good descriptor of corporate financing for Johannesburg Stock Exchange (JSE)-listed nonfinancial firms.Motivation for the study: There is limited evidence, if any, on how the GFC affected firms’ SOA.Research approach/design and method: This study used panel data drawn from 104 nonfinancial firms listed on the JSE and the partial adjustment model fitted with the random-effects tobit estimator (RE tobit).Main findings: The study firstly documents that JSE-listed nonfinancial firms had positive SOAs prior to, during and post the 2007–2008 GFC. Secondly, firms’ SOA decreased during the financial crisis period, meaning that a global negative economic shock reduces the SOA of all JSE-listed nonfinancial firms. Thirdly, financially constrained firms readily eliminate their target leverage deviation spreads, as they have a persistently higher SOA than financially unconstrained firms. Lastly, the SOA of financially unconstrained firms improved after the 2007–2008 GFC.Contributions/value-add: The dynamic trade-off theory is a good descriptor of the financing behaviour of JSE-listed non-financial firms. A negative economic shock reduces the firms’ SOAs.Practical/managerial implications: Managers should therefore maintain capital buffers in the form of cash reserves and lines of credit to reduce the impact of a negative economic shock on a firms’ SOAs.

Xanthelasma palpebrarum (XP) is the most common cutaneous xanthoma. It is triggered by hyperlipidemia, thyroid dysfunction, and diabetes mellitus. Madarosis, loss of eyebrows, occurs in various diseases ranging from local dermatological disorders to complex systemic diseases. Herein, we present a case of giant XP in a middle-aged female in whom bilateral partial madarosis developed. In polarized contact dermoscopy, the number of hairs on xanthoma plaque was reduced compared to normal.

Published: August 2022

Lethal midline granuloma is a rare aggressive, mutilating disorder of the upper airways. It is most likely secondary to natural killer/T-cell lymphoma and is difficult to diagnose owing to the varied and nonspecific symptoms. It is usually prevalent in the fourth decade of life and carries a poor prognosis. Our patient was a 19-year-old male with disease duration of 3 months, was diagnosed with lethal midline granuloma based on clinical examination, histopathology, and immunohistochemistry. The patient responded well to the first cycle of chemotherapy.

Published: August 2022

Background:

Limitations of echocardiography have long been known for the assessment of right ventricular (RV) systolic function in postoperative tetralogy of Fallot (TOF) patients. In this study, we evaluated the role of RV-global longitudinal strain (GLS) for the assessment of RV systolic function.

Materials and Methods:

It was a single institution prospective observational study of ninety postoperative TOF patients. Detailed 2-dimensional echocardiography along with RV-GLS using speckle tracing imaging was done at baseline and after 1 year. The children were divided into three groups based on duration since total correction, i.e., group A (6 months to 5 years), group B (6–10 years), and group C (>10 years) to assess the differences in RV systolic function. Furthermore, correlation of RV-GLS with RV-fractional area change (FAC), tricuspid annular plane systolic excursion, and tricuspid valve tissue Doppler imaging s' velocity was done.

Results:

In group A patients, a statistically significant increase in RV systolic function was seen over a period of 1 year. However, in group B and C patients, no significant change was seen. There was a strong positive correlation of RV-GLS only with RV-FAC during the first follow-up (r = 0.41, P < 0.01) and second follow-up periods (r = 0.67, P < 0.01).

Conclusion:

RV-GLS has a strong positive correlation with RV-FAC, and it detects preclinical regional myocardial dysfunction even when the RV-FAC is normal and thus must be included in the evaluation of postoperative TOF children.

Endodontic–periodontal combined lesions pose a treatment challenge for clinicians, especially when the lesion is persistent and does not show signs of healing after nonsurgical endodontics. This case report describes interdisciplinary management of a nonhealing combined lesion related to a periapical cyst through an integrated approach of apicoectomy and regenerative periodontics. A 51-year-old male patient presented with a sinus tract for 4 months after endodontic retreatment of the maxillary right central and lateral incisor. Surgical enucleation of the cystic lesion together with regenerative periodontics using bone graft, advanced platelet-rich fibrin plus membrane, and guided tissue regeneration membrane to treat the tunnel bony defect was done. Clinical and radiographic examination at 6 months showed resolution of lesion, reduction in probing depths, and good bone fill of the defect.

Gingival recession can lead to a variety of functional and esthetic problems. The problems associated with the gingival recession include unacceptable esthetics, hypersensitivity, root caries, and difficult plaque control. Gingival recession is a common clinical condition not only in populations with poor standards of oral hygiene but also in people maintaining good oral hygiene. In an esthetically driven era, the success of root coverage requires consideration of each one of the prognostic criteria. Various procedures have been popularized to treat the gingival recession. Zucchelli's technique is a modification of the coronally advanced flap for the treatment of teeth having multiple recessions. The upper hand of this procedure includes the absence of vertical releasing incisions, an appropriate thickness, combining sites of split and full thickness, and the coronal advancement of the flap. This case report presents the treatment of multiple adjacent gingival recessions using Zucchelli's coronally advanced flap.
