description: Reactions of silver(I) salts of acetate and trifluoroacetate with 1,3,5-triaza-7-phosphaadamantane (PTA) afforded 1-D coordination polymers [Ag(μ2-PTA-κ2P -:N)(μ2-O2CCH3-κ2O:O′)]n·2nH2O (1) and [Ag(μ2-PTA-κ2P:N)(μ2-O2CCF3-κO)]n·nH2O (2), while a reaction of silver(I)trifluoroacetate with N-methyl-1,3,5-triaza-7-phosphaadamantane (PTAMe) afforded the coordination polymer [Ag(PTAMe)(μ3-O2CCF3-κ3O:O:O’)(μ2-O2CCF3-κ2O:O′)]n (3). The coordination polymers were characterized using single-crystal X-ray diffraction. Nuclear magnetic resonance, infrared, and electron spray ionization mass spectrometries were used to initially establish complexation of Ag(I) to the PTA or PTAMe before recrystallization. In the crystal structures of 1 and 2, coordination of the PTA moieties to Ag(I) is via P and N forming chains that are linked through bridging carboxylates. The resulting structural motif can be described as ladder-like in which –[PTA–Ag–PTA]– chains are the strands while the bridging carboxylates comprising of –[Ag–O–C–O]2– or –[Ag–O]2– metallacycle rungs of the ladder. Compound 3 forms single-stranded coil-like coordination polymers with two non-equivalent Ag(I) centers, both tetrahedrally coordinated by four oxygens from four trifluoroacetates in one and by three oxygens from the trifluoroacetates and in each by the P of the PTAMe with alternating Ag⋯Ag interactions. The crystal structures of all three coordination polymers have a variety of fairly strong hydrogen bonds and intermolecular interactions which contribute stabilization of the crystal lattices.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: PyRQA is a software package that efficiently conducts recurrence quantification analysis (RQA) on time series consisting of more than one million data points. RQA is a method from non-linear time series analysis that quantifies the recurrent behaviour of systems. Existing implementations to RQA are not capable of analysing such very long time series at all or require large amounts of time to calculate the quantitative measures. PyRQA overcomes their limitations by conducting the RQA computations in a highly parallel manner. Building on the OpenCL framework, PyRQA leverages the computing capabilities of a variety of parallel hardware architectures, such as GPUs. The underlying computing approach partitions the RQA computations and enables to employ multiple compute devices at the same time. The goal of this publication is to demonstrate the features and the runtime efficiency of PyRQA. For this purpose we employ a real-world example, comparing the dynamics of two climatological time series, and a synthetic example, reducing the runtime regarding the analysis of a series consisting of over one million data points from almost eight hours using state-of-the-art RQA software to roughly 69 seconds using PyRQA.

description: Single phase multiferroics in which ordered magnetic and ferroelectricity coexist, are of great interest for new multifunctional devices, and among them Y-type hexaferrites are good candidates. Transverse susceptibility measurements, which have been proved to be a versatile tool to study singular properties of bulk and nanoparticle magnetic systems, have been carried out with a broadband system on polycrystalline Y type hexaferrites with composition Ba$_{0.5}$Sr$_{1.5}$Co$_2$Fe$_{12}$O${22}$, optimal to exhibit multiferroic properties. In the temperature range 80-350 K transverse susceptibility measurements with DC fields up to $\pm$5000 Oe reveal different behaviour depending on the sintering temperature. The thermal evolution of the anisotropy field peak exhibit four regions with different slopes: positive in 80-130 K, negative in 130-200 K, constant in 200-280 K and negative in 280-350 K, which can be considered a signature of spin transitions in this compound.

description: Discute-se as representações sociais que operam na constituição das questões das identidades de gênero a partir das animações cinematográficas dos contos de fadas. Trata-se de uma pesquisa bibliográfica com 26 animações cinematográficas dos contos de fadas analisados sob uma perspectiva pós-estruturalista – estudos culturais e estudos de gênero. Observa-se que as animações tradicionais reforçam estereótipos de gênero do modelo ideal de mulher e a submissão frente ao poder patriarcal, entretanto as produções contemporâneas expressam uma crítica em denúncia ao patriarcado e uma ruptura dos padrões arquetípicos normatizados. As animações Cinematográficas apresentam as representações de gênero legitimadas ou marginalizadas, produzindo um repertório de modelos naturaliza- dos na sociedade.

description: In his paper "The Mumford Dynamical System and Hyperelliptic Kleinian Functions" (see arXiv:2402.09218), Victor Buchstaber developed the differential-algebraic theory of the Mumford dynamical system. The key object of this theory is the (P,Q)-recursion introduced in his paper. In the present paper, we further develop the theory of (P,Q)-recursion and describe its connections to the Korteweg-de Vries hierarchy, the Lenard operator, and the Gelfand-Dikii recursion.

description: As well known, magnetic fields in space are distributed very inhomogeneously. Some-times field distributions have forms of filaments with high magnetic field values. As many ob-servations show, such a filamentation takes place in convective cells in the Sun and other astro-physical objects. This effect is associated with the frozenness of the magnetic field into a medium with high conductivity that leads to compression of magnetic field lines and forming magnetic filaments. We show analytically, based on the general analysis, that the magnetic field intensifies in the regions of downward flows in both two-dimensional and three-dimensional convective cells. These regions of the hyperbolic type for magnetic fields play a role of a specific attractor. This analysis was confirmed by numerical simulations for 2D convective cells of the roll-type. Without dissipation the magnetic field grows exponentially in time and does not depend on the aspect ratio between horizontal and vertical scale of the cell. An increase due to compression in the magnetic field in the high conductive plasma is saturated due to the natural limitation associated with dissipative effects when the maximum magnitude of the magnetic field is of the order of the root of the magnetic Reynolds number Rem. For the solar convective zone the mean kinetic energy density exceeds mean magnetic energy density at least for two orders of magnitude that allows one to use the kinematic approximation for the MHD induction equation. In this paper based on the stability analysis we explain why downward flows influence magnetic filaments from making them more flat with orientation along interfaces between convective cells.

description: O fim da II Guerra Mundial precipitou a necessidade de investir na educação como promotora do desenvolvimento. Da expansão das políticas públicas em educação com preocupações com a igualdade de oportunidades até à valorização do «local» e da cooperação entre os diferentes intervenientes locais, a educação compensatória foi assumindo um papel «remediador» das desigualdades sociais. Os programas de educação compensatória/políticas de educação prioritária expandiram-se desde a década de 1960 pelo mundo ocidental. Contudo, as críticas ao conceito e os resultados desanimadores dos primeiros programas, associados a alterações no quadro político, conduziram ao progressivo descrédito e desinvestimento por parte dos(as) decisores(as) políticos(as). O ressurgimento do conceito na década de 1980 marcou uma nova era para a educação compensatória, assente na descentralização e apostada na cooperação entre escolas e comunidades como estratégia de combate à exclusão escolar e social. Neste artigo revisitamos as características dos programas de educação compensatória, assim como os seus principais resultados. Por fim, refletimos sobre o potencial compensatório dos programas, em especial do programa português – Territórios Educativos de Intervenção Prioritária (TEIP).

description: Nowadays, technology is rapidly advancing: bots are writing comments, articles, and reviews. Due to this fact, it is crucial to know if the text was written by a human or by a bot. This paper focuses on comparing structures of the coarse-grained partitions of semantic paths for human-written and bot-generated texts. We compare the clusterizations of datasets of n-grams from literary texts and texts generated by several bots. The hypothesis is that the structures and clusterizations are different. Our research supports the hypothesis. As the semantic structure may be different for different languages, we investigate Russian, English, German, and Vietnamese languages.

description: We review the derivative expansion (DE) method in Casimir physics, an approach which extends the proximity force approximation (PFA). After introducing and motivating the DE in contexts other than the Casimir effect, we present different examples which correspond to that realm. We focus on different particular geometries, boundary conditions, types of fields, and quantum and thermal fluctuations. Besides providing various examples where the method can be applied, we discuss a concrete example for which the DE cannot be applied; namely, the case of perfect Neumann conditions in 2 + 1 dimensions. By the same example, we show how a more realistic type of boundary condition circumvents the problem. We also comment on the application of the DE to the Casimir-Polder interaction which provides a broader perspective on particle-surface interactions.

O objetivo é compreender aspectos da mitologia, do simbolismo e da espiritualidade Guarani na constituição de uma educação pautada na vivência integradora entre ação, emoção e razão como totalidade que reúne dimensões singulares, coletivas, culturais, econômicas e cosmológicas. Dimensões que emergem da integração entre a vivência e convivência com as narrativas míticas ameríndias como princípio educacional do modo de ser Guarani. O encontro com os Guarani contribui com interrogações ao modelo educacional ocidental ao favorecer, portanto, a consideração de outros princípios, outros modos de educar, que considerem a memória ancestral das narrativas míticas, o simbolismo que tece as manifestações do mistério, a espiritualidade que emerge das «belas palavras» – palavras sagradas – que enraízam e situam os Guarani no Tekoá, lugar no qual podem ser o que estão sendo.

description: Materials with strongly correlated electrons exhibit physical properties that are often difficult to predict as they result from the interactions of large numbers of electrons combined with several quantum degrees of freedom. The layered oxide perovskite Sr$_2$RuO$_4$ is a strongly correlated electron material that has been intensively investigated since its discovery due to its unusual physical properties. Whilst recent experiments have reopened the debate on the exact symmetry of the superconducting state in Sr$_2$RuO$_4$, a deeper understanding of the Sr$_2$RuO$_4$ normal state appears crucial as this is the background in which electron pairing occurs. Here, by using low-energy muon spin spectroscopy we discover the existence of magnetism at the surface of Sr$_2$RuO$_4$ in its normal state. We detect static weak dipolar fields yet manifesting below a relatively high onset temperature larger than 50 K, which reveals the unconventional nature of the observed magnetism. We relate the origin of this phase breaking time reversal symmetry to electronic ordering in the form of orbital loop currents that originate at the reconstructed Sr$_2$RuO$_4$ surface. Our observations set a reference for the discovery of the same magnetic phase in other materials and unveil an electronic ordering mechanism that can influence unconventional electron pairing with broken time reversal symmetry in those materials where the observed magnetic phase coexists with superconductivity.

description: Os projetos educativos de agrupamentos de escolas (PEA) de regiões de fronteira de Portugal Continental constituem o material empírico deste artigo. Reconhece-se, através da literatura, que existem desigualdades de oportunidades, também educacionais, nestas regiões. Neste artigo procura-se discutir, recorrendo à análise documental, o modo como escolas de fronteira se mobilizam na rela- ção com o local, nomeadamente com a comunidade e região. A análise sugere diferentes papéis das escolas nesta relação, quer posicionando-se como responsáveis por redes compreensivas para o desenvolvimento local, sensíveis a especificidades locais, quer assumindo uma relação de carácter mais funcionalista e instrumental. As estratégias de ação podem concretizar-se tanto através de um modelo próximo do trabalho em rede, como da abertura das escolas ao exterior. Os/as jovens, a escola, a comunidade ou o património cultural podem constituir-se como o objeto privilegiado desta relação. A análise permitiu ainda constatar que, nos PEA, reside uma intenção de considerar o local e a comunidade como relevantes na dinâmica da escola. Contudo, são raros os PEA que se apropriam, não de um local ou comunidade abstratos, mas de aspetos específicos, designadamente de fronteira.

description: While a stability theory has existed for a long time for the laminar capillary jet, there is a lack of theoretical approaches for the turbulent so far. Experimental results point out, however, that the decomposition mechanisms are similar for the laminar and turbulent case. Therefore, an attempt is made to transfer the approaches of the known stability theory, which in its base features goes back to Rayleigh, to the turbulent case. In order to study the effects of turbulence on the rotationally symmetric surface waves relevant in the laminar case, a model is set up that takes into account the coupling between the turbulent apparent stresses and the elongation of the liquid as a result of jet cross-section changes. This coupling is modeled using Batchelor and Proudman's "Rapid Distortion Theory"; however, the derived results are independent in their qualitative statement of this particular turbulence model. The result of this consideration is that homogeneous turbulence exerts a stabilizing influence on rotationally symmetric surface waves and may even lead to a prevention of this breakup mechanism.

description: To facilitate diagnosis on cardiac ultrasound (US), clinical practice has established several standard views of the heart, which serve as reference points for diagnostic measurements and define viewports from which images are acquired. Automatic view recognition involves grouping those images into classes of standard views. Although deep learning techniques have been successful in achieving this, they still struggle with fully verifying the suitability of an image for specific measurements due to factors like the correct location, pose, and potential occlusions of cardiac structures. Our approach goes beyond view classification and incorporates a 3D mesh reconstruction of the heart that enables several more downstream tasks, like segmentation and pose estimation. In this work, we explore learning 3D heart meshes via graph convolutions, using similar techniques to learn 3D meshes in natural images, such as human pose estimation. As the availability of fully annotated 3D images is limited, we generate synthetic US images from 3D meshes by training an adversarial denoising diffusion model. Experiments were conducted on synthetic and clinical cases for view recognition and structure detection. The approach yielded good performance on synthetic images and, despite being exclusively trained on synthetic data, it already showed potential when applied to clinical images. With this proof-of-concept, we aim to demonstrate the benefits of graphs to improve cardiac view recognition that can ultimately lead to better efficiency in cardiac diagnosis.

description: Background: Myocarditis is a condition that can have severe adverse outcomes and lead to sudden cardiac death if remaining undetected. This study tested the capability of cardiac magnetic field mapping to detect patients with clinically suspected myocarditis. This could open up the way for rapid, non-invasive, and cost-effective screening of suspected cases before a gold standard assessment via endomyocardial biopsy. Methods: Historical cardiac magnetic field maps (n = 97) and data from a state-of-the-art magnetocardiography device (n = 30) were analyzed using the Kullback–Leibler entropy (KLE) for dimensionality reduction and topological quantification. Linear discriminant analysis was used to discern between patients with ongoing myocarditis and healthy controls. Results: The STT segment of a magnetocardiogram, i.e., the section between the end of the S wave and the end of the T wave, was best suited to discern both groups. Using a 250-ms excerpt from the onset of the STT segment gave a reliable classification between the myocarditis and control group for both historic data (sensitivity: 0.83, specificity: 0.85, accuracy: 0.84) and recent data (sensitivity: 0.69, specificity: 0.88, accuracy: 0.80) using the KLE to quantify the topology of the cardiac magnetic field map. Conclusion: The implementation based on KLE can reliably distinguish between clinically suspected myocarditis patients and healthy controls. We implemented an automatized feature selection based on LDA to replace the observer-dependent manual thresholding in previous studies.

description: Purpose: Cancer initialization can be explained as a result of parasitic virus energy consumption leading to randomized genome chemical bonding. Materials and methods: Analysis of experimental data on cell-mediated immunity (CMI) containing about 12,000 cases of healthy humans, cancer patients and patients with precancerous cervical lesions disclosed that the specific cancer and the non-specific lactate dehydrogenase-elevating (LDH) virus antigen elicit similar responses. The specific antigen is effective only in cancer type of its origin but the non-specific antigen in all examined cancers. CMI results of CIN patients display both healthy and cancer state. The ribonucleic acid (RNA) of the LDH virus parasitizing on energy reduces the ratio of coherent/random oscillations. Decreased effect of coherent cellular electromagnetic field on bonding electrons in biological macromolecules leads to elevating probability of random genome reactions. Results: Overlapping of wave functions in biological macromolecules depends on energy of the cellular electromagnetic field which supplies energy to bonding electrons for selective chemical bonds. CMI responses of cancer and LDH virus antigens in all examined healthy, precancerous and cancer cases point to energy mechanism in cancer initiation. Conclusions: Dependence of the rate of biochemical reactions on biological electromagnetic field explains yet unknown mechanism of genome mutation.

description: O artigo em referência parte da discussão sobre a importância da educação para os valores no contexto africano, para se centrar na experiência angolana. Procuramos compreender os pressupostos pedagógicos e políticos que estão na ordem da inclusão da disciplina de educação moral e cívica no sistema educativo angolano. A nossa abordagem inicia‑se por uma breve análise histórica do sistema educativo desde a sua implementação, em 1978, ainda no auge da República Popular de Angola, procurando traçar as mudanças nos objetivos. Segue‑se uma análise de diversos documentos que dão corpo à disciplina de educação moral e cívica no sistema educativo angolano, mas atendendo também a alguns dados sobre a sua implementação. A relevância do papel da educação na construção da democracia é afirmada, em linha com a investigação contemporânea em vários países africanos.

description: Este artigo centra‑se na paisagem e na sua mais‑valia na construção da cidadania territorial, dimensão chave da educação geográfica. Apresenta‑se um projeto educativo inovador, sustentado no projeto «Tejo: Paisagem Cultural» e no Observatório da Paisagem do Tejo, enquadrado nos princípios da Convenção Europeia da Paisagem, que visa apoiar a recolha e a troca de informação, bem como o estabelecimento de protocolos e parcerias entre instituições públicas e comunidades locais, numa lógica de governança territorial. O artigo comporta três pilares de ação, que se interligam e complementam: a) enquadrar a paisagem no quadro da geografia; b) discutir a mais‑valia da paisagem na construção da cidadania territorial e no ensino‑aprendizagem da geografia; c) apresentar um projeto educativo centrado na paisagem e perspetivado no âmbito da relação escola‑município.

que é um modelo pedagógico?

description: A ideia de modelo tem sido ampla e, quase sempre, irrestritamente utilizada nas pesquisas acadêmicas circunscritas naqueles limites que, há pouco mais de dois séculos, nos acostumamos a denominar as ciências do homem. Nesse domínio, o uso de tal ideia tem despertado debates incontáveis, mas, relativa e paradoxalmente, uma atenção menor tem sido dedicada ao próprio problema da dedução do estatuto de objetividade dos modelos empregados. A partir do mapeamento destas dificuldades, o que se propõe é a construção de uma epistemologia alternativa do modelo, não de acordo com a maneira estritamente filosófico‑analítica com que ela vem sendo tratada e não contrária às outras de modo absoluto, mas anterior, elaborada a partir de um deslocamento para um nível dos discursos onde a distinção entre objetos práticos e teóricos é visada como o resultado da articulação de regularidades que os antecede e que pode ser colocada em questão.

description: O presente artigo tem como principais objetivos, por um lado, apresentar o quadro evolutivo do ensino superior à escala global e, por outro, refletir sobre como os países africanos têm reagido a essas dinâmicas globais, com especial ênfase para a realidade moçambicana. Metodologicamente, fez‑se uma revisão bibliográfica sobre as transformações no ensino superior no mundo, no contexto africano e em Moçambique, através da análise de fontes secundárias e do seu cruzamento com fontes primárias previamente selecionadas. Como principais constatações do estudo, destacam‑se, por um lado, que os padrões de funcionamento e de crescimento do ensino superior têm estado a ser decisivamente moldados pelo seu processo de internacionalização e que, por outro lado, a sobrevivência e a afirmação das universidades tende a ser medida em função da forma como elas reagem aos ditames das dinâmicas globais, estando em melhor posição aquelas que apostarem no mercado global de estudantes, conhecimento, tecnologias e cultura. No entanto, assume‑se também que as universidades dos países em desenvolvimento1, em particular as da África subsariana, têm uma lógica estruturante e de funcionamento relativamente diferente, não se enquadrando na lógica global de internacionalização.

description: Let n be a positive integer. We investigate the sequences ((Sm(n))m, which concerns the iteration of the odd divisor function S, given by In this article, we introduced and studied the following invariants: order, m-gonal shape number, type, convexity, and area of n derived from Sm(n). For m = 3, 4, 5, we classify m-gonal shape odd prime integers. According to some numerical computational evidence in the Appendix (see supplemental data), we state conjectures and questions with respect to the existence problem for m-gonal shape numbers. An inductive algorithm for finding m + 1-gonal shape prime integers when an m-gonal shape integer is given. We give some examples and illustrations, for our conjectures and questions.

description: Palaeoecological evidence (pollen, plant macrofossils and diatoms) is described from two peat sequences buried beneath alluvial silts and clays on the Gwent Levels to the southeast of Trowbridge, Cardiff. Radiocarbon dating shows that the peats are of late Holocene age. A negative sea-level tendency, dated to 3750 � 50 14C yrs BP (3900-4350 cal BP) marks the transition from tidal saltmarsh to coastal mire, after which an extensive alder carr developed in the near-shore area, while to landward were areas of mixed oak woodland. Alder carr was succeeded by reedswamp from 3400 � 70 14C yrs BP (4240-3820 cat BP), while tidal saltmarsh was re-established in the area early in the third millennium BP (2600-2800 14C yrs BP; 3050-2500 cat BP). There are indications throughout this period of extensive burning, although in the absence of unequivocal evidence in the pollen and plant macrofossil records for anthropogenic activity in the vicinity, it is possible that these could have been natural ( eg from lightning strikes) rather than being human-induced.
