Estimation of spectral spacing and linear ICI effects using IQ constellation images and CNN in gridless WDM systems
Authors: Martinez Zapata Kevin D. , Torres Jhon J. Granada
Published: December 2024

The estimation of spectral spacing (guard band) among optical channels
in gridless WDM systems would be decisive for making swift decisions
in reconfigurable optical add-drop multiplexers (ROADMs) to avoid
linear interchannel interference (ICI) effects during the channel
aggregation process in transit nodes. In this work, we propose a
method based on the construction of heat scatter images from
constellation diagrams along with convolutional neuronal networks
(CNN) to identify when optical channels are spectrally overlapped as
well as the value in GHz of the channel separation in a specific
optical channel without adjacent channels information. We validate our
method in a gridless 16-QAM Nyquist-WDM system with
different channel spacing and optical signal-to-noise ratio (OSNR).
Experimental results demonstrated that overlap detection can be
achieved with 3×16GBd accuracy. Additionally, the
estimation of spectral spacing achieved an error (RMSE) of less than
0.6 GHz. The penalty in accuracy and RMSE is only ∼98% and , respectively, when there is no
knowledge of the OSNR value. Thus, this method has the potential to be
integrated into monitoring tools designed for future dynamic gridless
optical transmission systems.

Dynamically switchable edge-detection and bright-field imaging based on a phase-change nonlocal metasurface
Authors: Guo Kenan , Xiao Shuyuan , Liu Tingting
Published: December 2024

Optical metasurfaces offer significant advantages in enhancing the speed, efficiency, and miniaturization of imaging systems. However, most existing metasurfaces are limited to static functionalities and lack reconfigurability, which is a key feature for practical applications in dynamic environments. In this work, we demonstrate a reconfigurable optical metasurface capable of switching between two distinct imaging functions (edge detection and bright-field imaging) within the visible spectrum. This reconfigurability is achieved by tuning the phase transition of antimony sulfide (Sb2S3), which controls the angular dependence of the magnetic dipole resonance. The phase transition of Sb2S3 from the amorphous phase to the crystalline phase enables different optical transfer functions, achieving high-performance imaging with a numerical aperture of 0.42, isotropic second-order differentiation, and high-resolution imaging, respectively. This approach allows for functional switching on a single surface, opening up possibilities for applications in medical imaging, optical sensing, and microscopy.
Megahertz-rate NO planar laser-induced fluorescence of reacting flows using tunable 5th harmonic Nd:YAG with A-X and B-X excitation
Authors: Leonov Boris , Grunbok Christopher , Miles Richard
Published: December 2024

This article presents the first demonstration of burst-mode nitric oxide planar laser-induced fluorescence measurement of a reacting environment via Nd:YAG 5th harmonic excitation. A tunable pulse-burst laser generated 1 ms bursts of resonant 213 nm radiation at 200 kHz, 500 kHz, and 1 MHz repetition rates with 16 mJ, 3.5 mJ, and 0.75 mJ average pulse energies, respectively. Nitric oxide, naturally formed in the vicinity of an oxy-acetylene flame, was targetted via three excitation schemes: γ(1,0), γ(1,0) + β(5,1), and β(4,1). The generated fluorescence was collected in two separate spectral windows to demonstrate the selectivity of the electronic excitation and explore new filtering approaches for high background luminosity environments: 240 nm - 260 nm and 275 nm - 375 nm. Overall, this new method of UV-light generation for nitric oxide excitation performed very well with a substantial amount of collected signal even with modest energy levels accessible at a 1 MHz rate. The primary advantage of utilizing the 5th harmonic to access nitric oxide resonances was its simplicity and robustness through direct burst mode laser up-conversion and simplified Master Oscillator, Power Amplified (MOPA) frequency control, obviating the need for an optical parametric oscillator.

Tuberculosis (TB) is the first infectious disease to be screened-out from specified pathogen-free cynomolgus macaques (Macaca fascicularis; Mf) using in human pharmaceutical testing. Being in either latent or active stage after exposure to the Mycobacterium tuberculosis complex (MTBC), the monkey gamma-interferon release assay (mIGRA) was previously introduced for early TB detection. However, a notable incidence of indeterminate results was observed. In this study, we compared two positive mitogen references, phytohemagglutinin (PHA) that is used in the QuantiFERON-TB Gold Plus kit (QFT-PHA) and a combination of Concanavalin A and Pokeweed mitogen (ConA+PWM), in a cohort of 316 MTBC-exposed Mf. Following a 29-month follow-up of 100 selected animals, we established a new mIGRA interpretation algorithm that demonstrated a significant shift in the negative and indeterminate cases regardless of whether the QFT-PHA or ConA+PWM was used as a mitogen. That is, if the ODNIL value was ≤0.18, ODMIT-NIL > ODNIL, and the ODTB1/2-NIL were ≥0.05 and ≥25% of individual ODNIL, the mIGRA result was interpreted as ‘positive’. If the ODNIL value was ≤0.18, ODMIT-NIL > ODNIL, and the ODTB-NIL was <0.05, the mIGRA result was interpreted as ‘negative’. If the ODNIL value was >0.18 or the OD of mitogen references [OD(QFT-PHA) and OD(ConA+PWM)] were ≤0.18, the mIGRA result was interpreted as ‘indeterminate’. As a result, negative cases increased by 10–50%, indeterminate cases decreased by 40–80%, and the number of TB-positive cases remained unchanged. Our findings highlight the critical role of mitogens as positive controls in mIGRA interpretation. This study provides the mIGRA value for the TB screening of cynomolgus macaques that enables the identification of true positive and suspicious TB cases for quarantine programs.
The kinaesthetics of assimilation in Sami Blood
Authors: Larsen Mads
Published: December 2024

Cinema is particularly suited for illuminating the kinaesthetic aspects of cultural subjugation. In Sameblod (Sami Blood) (2016), writer–director Amanda Kernell portrays the self-assimilatory journey of an indigenous 14-year-old girl as a result of forced and voluntary exposure to novel bodily experiences. Using as its conceptual point of departure the term ‘kinaesthesia’ – the body’s sensations of movement and spatiality – this article analyses the filmic techniques Kernell uses to offer audiences a vicarious experience of assimilation, and later, cultural revitalization. A century after majority-population Swedes subjected Kernell’s family and other Sámi to social Darwinian racism, the director’s third-eye film turns the camera back at those who portrayed them as inferior. Sami Blood exemplifies how important sensory and affective experiences are for our politics, histories and perception of cultural texts. The film is part of the past decades’ Sámi revitalization, an artistic movement in which screen media have played an important role.

XX, apresentamos, cronologicamente, alguns relatos que ilustram a ocorrência e distribuição geográfica de grandes incêndios nem Portugal continental, bem como o aparecimento dos Mega incêndios.
Arqueologia da Morte entre os séculos III e XIII na cidade de Lisboa
Authors: Dimas Filipa , Casimiro Sílvia
Published: December 2024

A investigação sobre o mundo funerário em contexto urbano, é limitada pela constante reutilização do espaço ao longo do tempo, bem como, pelos constrangimentos inerentes ao desenvolvimento de trabalhos arqueológicos em espaços urbanizados, o que dificulta uma leitura arqueológica das realidades envolvidas. Neste estudo exploram-se as dinâmicas da implantação dos contextos funerários do período compreendido entre os séculos III e XIII, no actual concelho de Lisboa onde, nos últimos anos, a arqueologia preventiva tem colocado a descoberto novas realidades. Para o efeito, foi desenvolvido um levantamento dos sítios tendo por base o Endovélico, recorrendo a critérios crono-espaciais, a par com fontes bibliográficas e documentais. O GeoPortal, foi essencial para a localização e inventariação dos 34 sítios, posteriormente mapeados com o software Quantum GIS. Pretende-se contribuir para o preenchimento de lacunas no conhecimento sobre a paisagem funerária no período compreendido entre o declínio da administração romana e a implementação de cemitérios paroquiais e, consequentemente, atendendo à separação do mundo dos mortos, do mundo dos vivos, para uma melhor leitura do urbanismo da cidade.
Aproximación paleodemográfica a una población altomedieval de la Península Ibérica
Authors: Martín-Alonso José Francisco , Maroto Benavides Rosa M. , G. Roca María , Coppola-Bove Lorenza , López-Gijón Ramón , Laffranchi Zita , Jiménez-Brobeil Sylvia A.
Published: December 2024

En este trabajo se analizan los datos del estudio antropológico y arqueológico del cementerio de Santa María de Tejuela que pueden aportar información sobre aspectos paleodemográficos. El número de individuos asciende a 182, aunque solo 125 tienen edad y sexo asignados. Hay más hombres que mujeres, y la mayoría fallecieron antes de cumplir los 41 años, no habiendo mujeres que vivieran más allá de los 61 años. El número de enterramientos de niños y jóvenes es bajo, y el índice juvenil estimado es significativamente más bajo que el de otras poblaciones contemporáneas de la región. Los subadultos muestran una mortalidad muy elevada en los primeros años de vida. Los resultados de mortalidad de los adultos son consistentes con los de una población rural medieval, con baja esperanza de vida promedio. La escasez de enterramientos infantiles y juveniles proporciona un perfil de mortalidad distinto al esperado en poblaciones preindustriales, no pudiendo atribuirse exclusivamente a factores tafonómicos o metodológicos. Posiblemente estemos ante una población con baja fecundidad, en la que podría haber emigrantes que no formaban familias en el lugar, lo que encajaría con la inestabilidad de la vida en una zona fronteriza.

Macrorrestos vegetais em contextos funerários: rituais, função e processos de formação
Authors: Tereso João Pedro , Costa Vaz Filipe
Published: December 2024

O uso de materiais vegetais foi, e ainda é, uma constante em contextos funerários das mais variadas cronologias, culturas e geografias, onde podem ter funções ou simbolismos variados. No entanto, sendo perecíveis, só se preservam em condições particulares e a sua identificação, recolha e estudo exigem métodos específicos. Este artigo aborda o potencial interpretativo de macrorrestos vegetais preservados através de carbonização e mineralização em contextos de cremação e inumação e fará uma avaliação dos principais desafios no seu estudo.
A madeira é o principal combustível utilizado em cremações. Porém, ainda que o fogo assuma usualmente um valor simbólico nestas práticas, o mesmo nem sempre acontece com a lenha utilizada. Em inumações, o uso intencional do fogo é mais raro, mas ter-se-á verificado desde a Pré-história, assumindo a função de preparação da área de enterramento.

Com o fogo também se conservam frequentemente objetos de madeira, frutas, sementes e restos de alimentos processados, fornecendo informações muito relevantes para caracterizar rituais. Algumas destes podem encontrar-se mineralizados, surgindo usualmente associados a com objetos metálicos.

Os Centros de Especialidades Odontológicas são ambulatórios de especialidade e referências para a Atenção Básica. Objetivo: Avaliar o desempenho dos Centros de Especialidades Odontológicas de Santa Catarina entre 2014 e 2019, considerando a Política Nacional de Saúde Bucal. Metodologia: Utilizaram-se dados do Sistema de Informação Ambulatorial do Sistema único de Saúde e do Cadastro Nacional de Estabelecimentos de Saúde para caracterizar cada tipo de Centro de Especialidades Odontológicas de acordo com os subgrupos de procedimentos odontológicos. As avaliações foram anuais e por macrorregião de saúde, usando o indicador de cumprimento global de metas, classificado em quatro categorias: ruim, regular, bom e ótimo. Resultados: O estudo incluiu 41 Centros de Especialidades Odontológicas: 51% tipo I, 42% tipo II e 7% tipo III. A periodontia atingiu a meta com maior percentual de procedimentos. Houve melhora no desempenho de 2014 a 2016 e redução a partir de 2017. Por macrorregião, predominou a classificação regular em quatro, ótimo em duas e ótimo/boa em uma. Conclusão: O desempenho dos Centros de Especialidades Odontológicas foi insatisfatório nas macrorregiões de Santa Catarina. Pretende-se que estes resultados contribuam na qualidade da assistência em saúde bucal e auxiliem a gestão das práticas odontológicas.

cultura de massa e o vazio existencial, totalitalismo e democracia
Authors: Feiler Adilson Felicio
Published: December 2024

Desde a fase de escrita de seu Para a genealogia da moral, Nietzsche desenvolveu um projeto marcado por uma desconfiança cada vez mais radical sobre as bases fundamentais da cultura. A aristocracia se depreende pela crítica que o filósofo realiza a toda a dimensão gregária, mediante a qual a cultura vem marcada. No decorrer deste trabalho será observado em que medida o esforço de Nietzsche é capaz de contribuir para o projeto político de domínio e de superação. A própria noção de aristocracia tem, na sua dimensão de radicalismo, a virtude como vontade de domínio, um de seus diferenciais. Seria esta virtude compreendida exclusivamente como força, e, por isso, despida da moral, informada pelo cristianismo como projeto civilizatório, para além da cultura de massa e do vazio existencial?
Creatividad polinizadora
Authors: Torre Saturnino de la
Published: December 2024

Para concluir este artículo, me permito mencionar algunos de los rasgos que podrían servir para caracterizar la creatividad polinizadora aplicada a las políticas públicas. Tres de estas características corresponden a tres principios de la polinización: generar mejoras permanentes (principio de evolución y pervivencia); carácter socializador (principio de cooperación). Aquí destacaría el carácter humano sobre el técnico o material; Equilibrio entre la tendencia a la unidad y a la diversidad (Principio de complementariedad) Los opuestos terminan siendo complementarios en algún momento, como la onda y la partícula, el día y la noche, la luz y la sombra, el blanco y el negro, ... Los opuestos son una forma de categorizar la realidad. Estos tres principios debieran regir las actuaciones de las políticas públicas. Generar mejoras que se mantengan en el tiempo, que vayan más allá de los periodos de gobiernos de los dirigentes. Ello se consigue con el diálogo y cooperación interinstitucional y entre partidos políticos. Es preciso terminar con leyes d que cambian al cambiar el partido político dominante por falta de diálogo y consenso. Y en tercer lugar conjugar lo global con lo local; lo colectivo con lo individual, porque no existen contrarios, sino complementarios desde una mirada compleja de la realidad. A ellos debo añadir rasgos como la flexibilidad en las actuaciones. Esa flexibilidad a la hora de tomar decisiones supone sopesar ventajas e inconvenientes y no aplicar las leyes o reglas porque así están establecidas. Valorar el factor humano por encima del material. Es la capacidad de adaptación teniendo en cuenta las circunstancias. Novedad en los planteamientos es avanzar con propuestas nuevas, diferentes a las existentes siempre que conlleven valor. No vale lo nuevo por ser nuevo ni lo joven por ser joven. Ha de ir acompañado de valor social. Colaboración durante todo el proceso. Las genialidades individuales son la excepción. Los avances suelen venir de la cooperación, tomando como base aportaciones anteriores. Es por ello por lo que la colaboración es clave en la subsistencia celular y en la política. Para el genetista Bruce Lipton (2007), la agrupación celular resulta fundamental para su subsistencia. La supervivencia no está en el dominio del más fuerte, como proponía Darwin, sino en la agrupación y cooperación. El resultado de esta forma sabia y creativa de proceder en políticas públicas (fructificación) es dejar marcas constructivas. Esas marcas son como el polen que liberado va transformando la sociedad evolutivamente. Esas marcas o huellas se perpetuán, generación tras generación, contribuyendo al bien común en forma creación de servicios, de instituciones o entidades culturales, educativas, artísticas, jurídicas, de salud; en nuevas construcciones al servicio del ciudadano. La polinización, escribe Vetterlein (2024),  tiene un papel fundamental en la ecoformación, En suma, contribuyen al progreso real de la sociedad.

Construcción y resignificación de Humboldt como espacio de la Pampa Gringa en la dramaturgia de María Rosa Pfeiffer
Authors: Notta Carolina Belén
Published: December 2024

En el presente artículo se analiza un corpus de textos dramáticos de María Rosa Pfeiffer desde los estudios comparados en Literatura y Teatro. En ellos se aborda la construcción de Humboldt como espacio perteneciente a la «zona» (Crolla, 2015) de la Pampa Gringa en la provincia de Santa Fe, donde la mirada de sus pobladores sobre el espacio pone en tensión la localidad y la extranjería, habilitando la pregunta: ¿cuál es mi patria? Por un lado, los inmigrantes suizo-alemanes, a partir del año 1868, entienden el espacio como lugar de llegada a la nueva tierra. Luego, la mirada de la nueva generación de habitantes desde 1970, mediada por la «escritura femenina» (Derrida, 2001), resignifica el espacio, proponiéndolo como lugar de partida para un nuevo viaje y permitiendo nuevas reflexiones sobre la pregunta acerca de la patria y la identidad de los pobladores de Humboldt en la actualidad.
Diálogo entre emigrantes nómadas: Marguerite Yourcenar y yo
Authors: Castellani Jean-Pierre Castellani
Published: December 2024

La relación de Yourcenar con el viaje aparece claramente en el itinerario de su vida reconstituido minuciosamente en biografías recientes, por su epistolario abundante que descubrimos de modo póstumo en el cual comenta detenidamente sus proyectos de viajes, sus experiencias sucesivas y las lecciones que saca de ellas. Nos parece interesante destacar un concepto original del viaje en Yourcenar que se armoniza con su filosofía de la vida y de relacionarla con unas obras suyas, lo que nos da una de las claves de su personalidad compleja y de sus personajes principales. Y completarlo por mi propia experiencia del viaje
L’émancipation par la communication

Published: December 2024

Cette contribution pose un regard historique sur les trajectoires de professionnalisation des communicants à travers l’étude de cas de la campagne prohibitionniste américaine du début du XXe siècle. À travers cette mise en perspective centrée sur l’exemple des femmes de la Fédération pour la Tempérance Scientifique, nous souhaitons remettre au cœur de nos analyses la part d’héritage qui sous-tend les pratiques des professionnels de l’information et de la communication et rendre compte de l’influence du militantisme, de la religion, de la bureaucratie ou encore de l’industrie dans le processus de stabilisation des compétences professionnelles en communication.
El arbitraje laboral individual
Authors: Sánchez del Olmo Víctor
Published: December 2024

La presente obra aborda el estudio integral del arbitraje laboral individual. En este sentido, la monografía comienza con unos primeros capítulos analizando la fundamentación y marco general del sistema arbitral individual como mecanismo de resolución de conflictos individuales. Así, se profundiza sobre su origen y definición, su ubicación normativa y la tipología de arbitrajes. Tras ello, se analiza el sistema arbitral individual a la luz de la Constitución española con el ánimo de verificar que aquel resulta compatible con el derecho fundamental a la tutela judicial efectiva y resulta respetuoso, de igual modo, con el mandato de reserva de jurisdicción. Seguidamente, se trata la voluntariedad como principio vertebrador del sistema. Sin solución de continuidad, se aborda la reflexión que surge a partir del contacto del arbitraje laboral individual con el principio de indisponibilidad de los derechos laborales. Tras ello, la monografía se centra en el análisis individualizado de las instituciones que componen el arbitraje laboral individual, en lo que supone el Capítulo más centrado en el sistema arbitral individual y su estructura. De este modo, se estudia la normativa, no exclusivamente laboral, que pueda tener relevancia para establecer un sistema homogéneo que garantice el buen funcionamiento del mecanismo, dando prioridad a los intereses y derechos de las partes. Se finaliza este Capítulo con la exposición de los conflictos que parecen tener un mejor encaje en el sistema arbitral individual.
Sertifikasi Halal Produk Pangan Impor: Analisis Hukum Perlindungan Konsumen
Authors: Saviera Lesly
Published: December 2024

Globalisasi telah menyebabkan terjadinya peningkatan perdagangan internasional yang signifikan. Hal ini berdampak pada kebebasan konsumen dalam memilih berbagai macam produk dari berbagai negara. Sertifikasi halal menjadi isu krusial di Indonesia, dikarenakan dengan jumlah penduduk muslim yang tinggi.. Tulisan ini menganalisis perlindungan hukum konsumen melalui sertifikasi halal produk pangan impor. Sehingga diketahui bagaimana peraturan perundang-undangan di Indonesia mengatur kebijakan sertifikasi halal produk pangan impor. Masalah ini diatur dalam Undang-Undang Nomor 8 Tahun 1999 tentang Perlindungan Konsumen, Undang-Undang Nomor 33 Tahun 2014 tentang Jaminan Produk Halal, dan Undang-Undang Nomor 18 Tahun 2012 tentang Pangan. Metodologi penelitian yuridis normatif yang digunakan dalam publikasi ini melibatkan pemeriksaan produk hukum seperti Peraturan Perundang-Undangan dan Peraturan Pemerintah.. Studi ini menunjukkan bahwa hukum Indonesia mewajibkan sertifikasi halal untuk produk makanan domestik dan impor. Badan Penjaminan Produk Halal (BPJPH) bertanggung jawab untuk mengawasi proses ini. Pemerintah melalui BPJPH, BPOM (Badan Pengawas Obat dan Makanan), dan lembaga terkait lainnya memiliki peran sebagai pemantau dan memberikan kepastian hukum bahwa produk pangan yang beredar di Indonesia memenuhi persyaratan halal. Kolaborasi antara pemerintah dan masyarakat juga penting untuk menjaga integritas proses sertifikasi halal di Indonesia.
