Authors: Safavi Mostafa , Khajehnasiri Amirahmad , Ezzati Reza , Rezabeyk Saeedeh 
Published: January 2024

Abstract
This paper proposes a new operational numerical method based on Touchard wavelets for solving fractional pantograph differential equations.
First, we present an operational matrix of fractional integration as well as the fractional derivative of the Touchard wavelets.
Then, by approximating the fractional derivative of the unknown function in terms of the Touchard wavelets and also by using collocation method, the original problem is reduced to a system of algebraic equations.
Finally, to show the accuracy and the validity of the proposed technique, we provide some numerical examples.
Lockerungen im österreichischen Maßnahmenvollzug –
Authors: Stempkowski Monika 
Published: January 2024

Zusammenfassung
Lockerungsmaßnahmen in Form von begleiteten und unbegleiteten Ausgängen sowie Phasen des Probewohnens ermöglichen während der Haft einen Kontakt zur Außenwelt und eine Vorbereitung des sozialen Empfangsraums für die Zeit nach der Entlassung aus dem Vollzug. Im Maßnahmenvollzug (dem österreichischen Pendant zum deutschen Maßregelvollzug) dienen sie darüber hinaus als wesentliche Informationsquelle, ob eine untergebrachte Person ausreichend für ein Leben in Freiheit vorbereitet ist und daher eine bedingte Entlassung erfolgen kann. In der vorliegenden Untersuchung wird die Praxis der Durchführung von Lockerungsmaßnahmen im Maßnahmenvollzug für psychisch kranke Personen beleuchtet. Die Ergebnisse zeigen auf, dass zwar die meisten Personen Lockerungen durchlaufen, aber individualisiert entschieden wird, welche und wie viele Formen von Lockerungen zu Einsatz kommen. Betrachtet man gleichzeitig die Behandlungen im Vollzug (bspw. durch den psychiatrischen oder den sozialen Dienst), Maßnahmen des Entlassungsmanagements, gerichtlich angeordnete Weisungen und die Häufigkeit einer Entlassung in eine betreute Nachsorgeeinrichtung, zeigt sich, dass sich Lockerungen in die jeweilige Behandlungsstrategie dahingehend eingliedern, dass jene Personen, die mehr Behandlung, mehr Nachbetreuung und mehr Kontrolle erfahren, auch häufiger Lockerungen durchlaufen. Bezogen auf die Wiederkehrerrate nach der bedingten Entlassung zeigen sich hingegen keine Unterschiede zwischen Personen mit mehr bzw. weniger Lockerungen. Im Sinne des Risk-Need-Responsivity-Modells kann vermutet werden, dass die Selektion für diese unterschiedlichen Behandlungsintensitäten in dem jeweiligen Rückfallrisiko der Personen begründet liegt. Ist dies der Fall, deuten die Ergebnisse darauf hin, dass die Differenzierung zwischen Personen mit hohen und niedrigem Risiko gelingen dürfte. Mögliche Hintergründe dieser Auswahl und sich daraus ergebende Forschungsfragen werden diskutiert.

Abstract
We propose a tunable all-dielectric zero-index metamaterial based on phase change material. By constructing the alternating rod structure with phase change material and silica material, the zero-refractive index characteristic is realized. In order to verify the equivalent zero-index characteristic, we calculated the electromagnetic field distribution at center frequency. Based on phase invariance, it was found that this kind of metamaterial can achieve equivalent zero refractive index characteristics. To further achieve the polarization-insensitive zero refractive index, we propose a metamaterial structure based on the fishing nets structure. Based on the S-parameter inversion algorithm, the equivalent dielectric constant, equivalent permeability, equivalent impedance, and equivalent refractive index of the metamaterial were extracted. Based on the extracted equivalent parameters and the corresponding electromagnetic field distribution, the designed all-dielectric metamaterial has the tunable equivalent zero refractive index characteristic.

Zusammenfassung
Die stetig voranschreitende Entwicklung im Bereich der Fertigung optischer und elektronischer Elemente auf Basis von Nanotechnologien führt seit Jahren zu einer steigenden Nachfrage nach hochpräzisen Nanomess- und Nanofabrikationsmaschinen (The International Roadmap For Devices And Systems, IEEE, 2020; C. Grant Willson and B. J. Roman, “The future of lithography: SEMATECH litho forum 2008,” ASC Nano, vol. 2, no. 7, pp. 1323–1328, 2008). Als technologisch besonders anspruchsvoll hat sich dabei die Fabrikation auf stark geneigten, gekrümmten, asphärischen und freigeformten Oberflächen herausgestellt (R. Schachtschneider, et al., “Interlaboratory comparison measurements of aspheres,” Meas. Sci. Technol., vol. 29, no. 13pp, p. 055010, 2018). Aufbauend auf den zukunftsweisenden Entwicklungen der Nanopositionier- und Nanomessmaschine 1 (NMM-1) (G. Jäger, E. Manske, T. Hausotte, and J.-J. Büchner, “Nanomessmaschine zur abbefehlerfreien Koordinatenmessung,” tm – Tech. Mess., vol. 67, nos. 7–8, pp. 319–323, 2000) und der Nanopositionier- und Nanomessmaschine 200 (NPMM-200) (E.

Im folgenden Artikel wird davon ausgehend die mechanische und metrologische Charakterisierung der parallelkinematisch aktuierten Rotationserweiterung präsentiert. Hierbei konzentrieren sich durchgeführte Untersuchungen primär auf die kinematisch verursachten Abweichungen des Tool Center Point (TCP) sowie die Detektierung dieser Abweichungen mit einem interferometrischen In-situ-Referenzmesssystem. Darüber kann perspektivisch eine geregelte Kompensation der auftretenden TCP-Abweichungen erfolgen.
Devenir otras. Alternativas sensibles contra la violencia en la literatura escrita por mujeres en México
Authors: Cabrera Manuel María Isabel 
Published: January 2024

Ante los hechos violentos que la población y en particular las mujeres padecen como grupo en México, este trabajo busca sumar al ejercicio crítico de pensar las violencias simbólicas y fácticas, mostrar sus formas de reconocimiento y el trabajo discursivo que apuesta por la vida de las mujeres y la población vulnerable no sólo desde el dolor y la rabia, sino también desde la apuesta por la supervivencia, por las estrategias que permitirían sustraerse al peso avasallador de sus formas, para devenir otras. Este trabajo analiza el trabajo de escritoras que invitan a encontrar en sus reflexiones, historias, relatos y personajes femeninos no sólo a víctimas, sino a subjetividades que evitan por diferentes medios a quedar aprisionadas por conceptos que sólo reiteran la violencia en sus cuerpos y en sus vidas.

The (in)Functioning of the United Nations Security Council in the Context of Russian Aggression: is it Naive to Expect Change?
Authors: Jokšaitė Adriana , Jakovleva Kristina 
Published: January 2024

Russia’s aggression against sovereign Ukraine in February 2022 has once again highlighted the shortcomings of the UNSC mechanism. The UNSC, which continues the work of its predecessor, the League of Nations, and which has the mission of maintaining world peace and security, is incapable, in the context of the war in Ukraine, of adopting the necessary resolutions and other actions that would help to put an end to the ongoing aggression.
The planned reforms of the UNSC have not been implemented in the past, and therefore face the insurmountable obstacle of Russia, one of the 5 permanent members, being the aggressor state and constantly vetoing UNSC resolutions. Both the requirements for amending the UN Charter itself and the voting process legally make it impossible to remove Russia from the UNSC unless the aggressor itself votes to remove its delegation from the UNSC. Observing Russia’s actions during the war in Ukraine, it is safe to say that Russia will not give up the opportunity to continue to enjoy the place in the SC that it took over from the USSR after its collapse in 1991. An analysis of the practice of international law and the historical context in which the UNSC operates leads to the conclusion that the UNSC is currently functioning as an organisation that is unable to fulfil its core functions due to the limitations of the UN Charter. It is hardly possible to revive an organisation in which the aggressor state and the violator of international law have veto power.
Criminal Liability for a Private Party in Outer Space
Authors: Lapienytė Kristina , Prakopaitė Meda 
Published: January 2024

This article analyses whether a private party can be a subject of a criminal deed, since till now this issue has not been exhaustively consolidated either in the legal acts of the Republic of Lithuania nor foreign countries, therefore a necessity arises to ensure that there are no gaps in law that could determine the fact that criminal law would not fulfil a protective function, in other words, the interests of the individual, the society and the state would not be secured.
The article evaluates where the limit is, when space law comes into force and analyzes the legal regulation of outer space. Future problems related to space tourism are revealed and the problem of committing a criminal offence in outer space is assessed.
The analysis carried out in this work shows that the issues of criminal jurisdiction and criminal liability for a private party is quite problematic, as the provisions of many significant international agreements are unclear and differently evaluated. However, the aforementioned problematic issues can be resolved based on the systematic application of legal sources.
Polyphyllin II inhibits NLPR3 inflammasome activation and inflammatory response of Mycobacterium tuberculosis–infected human bronchial epithelial cells
Authors: Cheng Guodong , Ye Gengzhi , Ma Ying , Wang Yuqing 
Published: January 2024

Background: The bronchial infection by Mycobacterium tuberculosis (Mtb) is increasing in prevalence and severity worldwide. Despite appropriate tuberculosis treatment, most patients still develop bronchial stenosis, which often leads to disability. Polyphyllin II (PP2) is a steroidal saponin extracted from Rhizoma Paridis. In this study, we aimed to explore the effect of PP2 on the advancement of Mtb-induced bronchial infection.
Method: The effects of PP2 on cell viability were measured by using MTT and lactate dehydrogenase (LDH) kit. The mRNA and protein levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-8 were elucidated by RT-qPCR and ELISA, respectively. The expression of NLR family pyrin domain containing 3 (NLRP3) related inflammasome (NLRP3, IL-1β, and cleaved-caspase-1) and the activated degree of protein kinase B (AKT)/nuclear factor-kappa B (NF-kB; p-AKT and p-NF-κB) were detected by Western blotting.
Results: PP2 at 0, 1, 5, and 10 μM had little cytotoxicity on 16HBE cells. PP2 inhibited Mtb-induced cell proliferation and decreased LDH levels. We further found that PP2 could suppress Mtb-induced inflammatory responses and activation of NLPR3 inflammasome. Additionally, the role of PP2 in Mtb is associated with the AKT/NF-kB signaling pathway.
Conclusion: PP2 inhibited Mtb infection in bronchial epithelial cells, by inhibiting Mtb-induced inflammatory reactions and activation of NLPR3 inflammasome. These effects may be exerted by suppressing the AKT/NF-kB pathway, which will provide a prospective treatment.
Countee Cullen's Harlem Decadence
Authors: Volpicelli Robert 
Published: January 2024

AbstractThis essay responds to Countee Cullen's reputation within Harlem Renaissance studies as an out-of-date poet who had little concern for the “new” by reassessing his career under the sign of an older, nineteenth-century decadence. In so doing, it stages a larger exploration of the intersection between decadence and the Harlem Renaissance. I begin by sketching a genealogy of African American decadence that extends from W. E. B. Du Bois to second-generation Harlem writers like Richard Bruce Nugent and Wallace Thurman. I highlight Cullen's place within this lineage by examining the poetry from his 1927 Copper Sun in relationship to Charles Cullen's decadent illustrations for that volume. I conclude by showing how Cullen distinguishes himself among other Harlem writers in the way he uses decadence's investments in decay and afterlife to complicate the progressive views of history inherent to both the Harlem Renaissance and the New Negro movement.
Patrimônio líquido de Macapá, Amapá: mapeamento das áreas de ressaca
Authors: Spíndola Raysa Oliveira , Drach Patricia R C 
Published: January 2024

As cidades, dada sua complexidade, estão em constante processo evolutivo e as alterações acontecem em todos os segmentos. Ao estudar a forma urbana é possível entender como as diversas partes da cidade se ordenaram e se interconectaram, integrando o conjunto maior. Para o entendimento das dinâmicas presentes na relação das áreas de ressaca na cidade de Macapá, Amapá, nesta pesquisa foi construída uma linha do tempo a partir da definição dos períodos históricos. Foram considerados relevantes para a cidade os períodos evolutivos que correspondem a eventos que impulsionaram alterações importantes no processo administrativo com implicações diretas no tecido urbano da cidade. Foram, assim, definidos como marcos a fundação da Vila de São José de Macapá, passando pela criação do Território Federal do Amapá e, finalmente com a criação do Estado do Amapá. Os mapas com a evolução urbana da cidade foram produzidos atendendo a estes eventos e, portanto, abrangem o período da fundação em 1758 até o ano de 2020. Para o mapeamento síntese das áreas de ressaca compreendidas no meio urbano de Macapá, foi elaborado um mapa com a indicação de cada área. O processo de urbanização desordenado, aumentado pela migração, resulta em graves problemas sociais enfrentados pelas cidades. Um deles, a falta de moradias, resulta na ocupação das regiões próximas aos núcleos urbanos ainda não ocupados, agregando à cidade novas regiões morfológicas. Esta região apresenta um importante conjunto de áreas de ressaca (áreas úmidas) que estão compreendidas dentro da área urbana da cidade, em que estão sujeitas a profundas transformações ambientais, como o processo de aterramento que vem acontecendo ao longo dos anos.
Unsupervised Deep Feature Learning for Icequake Discrimination at Neumayer Station, Antarctica

Published: January 2024

Abstract
Unsupervised machine learning methods are gaining attention in the seismological community as more and larger datasets of continuous waveforms are collected. Recently, contrastive learning for unsupervised feature learning has shown great success in the field of computer vision and other domains, and we aim to transfer these methods to the domain of seismology. Contrastive learning algorithms use data augmentation to implement an instance-level discrimination task: The feature representations of two augmented versions of the same data example are trained to be similar, when at the same time dissimilar to other data examples. In particular, we use the popular contrastive learning method SimCLR. We test data augmentation strategies varying amplitude and frequency of seismological signals, and apply contrastive learning methods to automatically learn features. We use a dataset containing various mostly cryogenic waveforms detected by an STA/LTA short-term average/long-term average algorithm on continuous waveform recordings from the geophysical observatory at Neumayer station, Antarctica. The quality of the features is evaluated on a hand-labeled dataset that includes icequakes, earthquakes, and spikes, and on a larger unlabeled dataset using a classical clustering method, k-means. Results show that the approach separates the different hand-labeled groups with an accuracy of up to 88% and separates meaningful groups within the unlabeled data. Thus, we provide an effective tool for the unsupervised exploration of large seismological datasets and the automated compilation of event catalogs.
Impact of Lossy Compression Errors on Passive Seismic Data Analyses
Authors: Issah Abdul Hafiz S. , Martin Eileen R. 
Published: January 2024

Abstract
New technologies such as low-cost nodes and distributed acoustic sensing (DAS) are making it easier to continuously collect broadband, high-density seismic monitoring data. To reduce the time to move data from the field to computing centers, reduce archival requirements, and speed up interactive data analysis and visualization, we are motivated to investigate the use of lossy compression on passive seismic array data. In particular, there is a need to not only just quantify the errors in the raw data but also the characteristics of the spectra of these errors and the extent to which these errors propagate into results such as detectability and arrival-time picks of microseismic events. We compare three types of lossy compression: sparse thresholded wavelet compression, zfp compression, and low-rank singular value decomposition compression. We apply these techniques to compare compression schemes on two publicly available datasets: an urban dark fiber DAS experiment and a surface DAS array above a geothermal field. We find that depending on the level of compression needed and the importance of preserving large versus small seismic events, different compression schemes are preferable.
Educadores sociais portugueses: Pertinência, formação e identidade profissional em (re)construção
Authors: Azevedo Silvia , Ferreira Bruno , Luísa Cláudia , Rodrigues Vanda 
Published: January 2024

A Educação Social é uma profissão social e educativa que veio colaborar na cla-rificação de competências face a outras áreas similares, nomeadamente de profissões de ação social, com mais anos de intervenção em Portugal. A identidade profissional dos educadores sociais tem sido realizada pela práxis dos próprios profissionais, mas também fortemente fomentada pela Associação Profissional que os re-presenta, a Associação dos Profissionais Técnicos Superiores de Educação Social (APTSES). O associativismo e os seus movimentos sociais têm sido cruciais no desenvolvimento da profissão e do perfil do educador social. Num panorama de transformações e dinâmicas sociais inesperadas, pautadas ao longo destes últimos anos pela Pandemia da COVID-19 e pela ocupação da Ucrânia pelas tropas russas, a Educação Social revela-se um campo profissional em expansão, cujos instrumentos e metodologias de intervenção exigem uma adequação e avaliação contínuas, uma nova formalização, compromisso e legitimação profissional e científica.

Published: January 2024

Objective: Recurrent aphthous stomatitis (RAS) is a common ulcerative inflammatory condition of the oral mucosa. Considering the contradictory findings of previous research about the association between anxiety and RAS, the present study aimed to determine the prevalence of RAS and its association with anxiety among dentistry students.
Methods: In this descriptive-analytical study, a total of 241 dentistry students of G. University were divided into two groups (those with a history of RAS and healthy subjects) after recording their demographic and required information. Also, Cattell’s questionnaire was used to evaluate the level of anxiety. The results were analyzed using SPSS v.21 software, and a p-value of <0.05 was considered statistically significant.
Results: 2.40% of subjects suffered from RAS. This condition was more prevalent in winter, and its incidence was significantly different between the two groups in terms of the presence of a family history of RAS (p=0.01), food allergy (p=0.05), and regular exercise (p=0.040). Subjects with RAS had a significantly higher anxiety intensity in the areas of lack of ego strength, superego susceptibility, and ergic tension compared to subjects without RAS (p<0.0001).
Conclusion: The results showed that some areas of anxiety, including lack of ego strength, can be predictors of RAS. Therefore, teaching life skills such as anxiety management and its timely diagnosis and treatment can play an essential role in the prevention and treatment of RAS.
