Speculating with the body: Imagining designs for women’s embodied empowerment within the practice of feminist self-defense

Nikolovska, Bojana January 2024 (has links)
Feminist self-defense is a form of victim prevention training with a plethora of positive physical, mental, and social outcomes. In Human-Computer Interaction (HCI) self-defense is still a relatively under-researched topic. As such, inspired by HCI’s recent interest in feminist causes and corporeal practices, the goal of the study is to explore how embodied interaction design can empower beginner self-defense practitioners. To do so, the study was conducted via two methods: semi-structured interviews with students and teachers, and a participatory speculative design workshop with novice practitioners. This resulted in several speculative design concepts based on the use of felt experiences as a design resource. The concepts demonstrate how design can be used as a vehicle for imagining feminist technology that challenges gender norms and plays the role of scaffolding for cultivating embodied empowerment.

L'eau de l'art contemporain : une dynamique d'une esthétique écosophique / Water of Art : a dynamic of ecosophical aesthetics

Marty, Patrick 19 December 2014 (has links)
L’eau est porteuse d’aspects différents de consciences, tout en étant un espéranto planétaire. Doit-on parler des artistes de l’eau ? ou bien de l’eau des artistes ? Quel que soit le point de vue que l’on considère, il se dégage une synergie de pensées oeuvrant à une réflexion consensuelle et paradigmatique. Cette recherche propose une nouvelle lecture de l’interaction de l’élément naturel avec la place qu’il occupe dans l’art contemporain ; comment l’eau dans l’art contemporain devient, grâce à sa puissance évocatrice, l’Eau de l’Art, une source inépuisable d’adaptabilité transculturelle qui se fait l’écho d’une nécessaire métamorphose. L’eau est devenu un médium parmi tant d’autres. L'eau, matière naturelle par excellence, se retrouve utilisée indifféremment par un peu tous les courants artistiques actuels notamment dans des vidéos, des performances, des sculptures, en architecture ou dans des expériences à la frontière de l’art et des sciences cognitives. On peut examiner trois aspects de la culture de l'eau : en tant que vecteur à la fois d'une culture enracinée, et d'une éthique de l'Universel commun, la force symbolique de l'eau dans l'histoire de l’art, et l'actualité écologique, scientifique et psychologique. L’eau couvre tous les champs du possible, et rend accessible les moindres recoins de la pensée, aussi bien la part d’ombre que la lumière de la psyché humaine. Elle accompagne et interagit sur les non dits des sociétés, car elle contient leurs savoirs ; elle est la matrice de leur philosophie, leur sociabilité, leur géographie (compréhension de l’espace et des milieux de vie), leur communication, leur histoire, leur langage. L’Eau de l’Art dynamise ainsi une esthétique écosophique en puisant dans la poésie du temps. / Water is a messenger of various aspects of consciousness, while being a global Esperanto. Should we talk about artists of water? Or the water of artists? Whatever point of view one considers, a synergy of thoughts emerges involving a consensual and paradigmatic vision. This research proposes a new reading of the interaction of the natural element with its role in contemporary art; how water in contemporary art becomes, with its evocative power, Water of Art, an inexhaustible source of crosscultural adaptability that echoes a necessary metamorphosis. Water has become a medium among many others. Water, a natural material par excellence, is used interchangeably by almost all the current artistic trends, including video, performance, sculpture, architecture and experiences on the frontier of art and cognitive science. There are three aspects of the culture of water: as a vector of both an ingrained culture and the Universal ethic; the symbolic force of water in art history; and the ecological, scientific and psychological information. Water covers all possible fields, and allows access to every corner of the mind, the dark side as well as the light of the human psyche. It supports and interacts on the unspoken aspects of society because it contains their knowledge; it is the matrix of their philosophy, their sociability, their geography (understanding of space and living environments), communication, history, language. Therefore, Water of Art adds a dynamic to ecosophical aesthetics in drawing from the poetics of time.

Optimalizace stroje s permanentními magnety na rotoru pomocí umělé inteligence / Optimization of the permanent magnet machine based on the artificial inteligence

Kurfűrst, Jiří January 2013 (has links)
The dissertation thesis deal with the design and the optimization of the permanent magnet synchronous machine (SMPM) based on the artificial intelligence. The main target is to apply potential optimization methods on the design procedure of the machine and evaluate the effectiveness of optimization and the optimization usefulness. In general, the optimization of the material properties (NdFeB or SmCo), the efficiency maximization with given nominal input parameters, the cogging torque elimination are proposed. Moreover, the magnet shape optimization, shape of the air gap and the shape of slots were also performed. The well known Genetic algorithm and Self-Organizing migrating algorithm produced in Czech were presented and applied on the particular optimization issues. The basic principles (iterations) and definitions (penalty function and cost function) of proposed algorithms are demonstrated on the examples. The results of the vibration generator optimization (VG) with given power 7mW (0.1g acceleration) and the results of the SMPM 1,1kW (6 krpm) optimization are practically evaluated in the collaboration with industry. Proposed methods are useful for the optimization of PM machines and they are further theoretically applied on the low speed machine (10 krpm) optimization and high speed machine (120 krpm) optimization.

Estudo de transistores orgânicos por espectroscopia vibracional não linear e microscopia por modulação de carga / Study of organic transistors by nonlinear vibrational spectroscopy and charge modulation microscopy

Gomes, Douglas José Correia 13 April 2018 (has links)
Esta Tese aborda o estudo de transistores por efeito de campo orgânicos (OFETs do inglês, Organic Feld-Effect Transistors). Entender o comportamento da carga acumulada no canal do OFET, a qual é responsável pelo processo de condução elétrica no dispositivo, é de grande importância para ajudar a melhorar sua eficiência ou a propor um modelo teórico que descreva o comportamento do transistor em todos os seus regimes de operação. Vários trabalhos na literatura investigam o campo elétrico na camada semicondutora do transistor (ao longo do canal) gerado pela acumulação de cargas, porém nenhum investiga o campo na camada dielétrica de OFETs, que é diretamente proporcional à carga acumulada no canal. Investigou-se inicialmente o campo elétrico na camada dielétrica do dispositivo por meio da espectroscopia vibracional por Geração de Soma de Frequências (espectroscopia SFG do inglês, Sum-Frequency Generation). Espectros SFG obtidos nos dispositivos polarizados exibiram uma banda em ~1720 cm-1, devido ao grupo carbonila da camada dielétrica orgânica (PMMA – poli(metil metacrilato)), cuja a amplitude foi proporcional à voltagem de porta aplicada, indicando que esses grupos polares foram orientados sob ação do intenso campo elétrico no dispositivo. Esse sinal SFG induzido pelo campo pode ser devido a duas contribuições, um termo não linear de segunda ordem (devido à reorientação molecular) e outro de terceira ordem (interação entre os campos ópticos e o campo estático no volume do material). Observamos uma redução quase completa do sinal SFG em altas temperaturas (próximas da Tg do polímero dielétrico), indicando que o mecanismo de reorientação molecular é o responsável pelo sinal SFG gerado. Foram realizadas então medidas preliminares de microscopia SFG para mapear esse sinal SFG ao longo do canal de OFETs a base dos polímeros N2200 (semicondutor) e PMMA (dielétrico). Os resultados conseguem demonstrar a variação da densidade de carga acumulada no canal quando o dispositivo está polarizado e próximo à saturação. Usando Microscopia por Modulação de Carga (microscopia CMM do inglês, Charge Modulation Microscopy), que é outro método não invasivo para investigar a acumulação de cargas em um dispositivo operando, mapeamos a distribuição de carga no canal desses OFETs com alta resolução espacial (sub-micrométrica). Além disso, uma simulação da densidade de carga esperada e dos perfis de CMM foi realizada usando um modelo ambipolar para OFETs. Com base nessas simulações, propusemos uma modulação de onda quadrada do OFET, que permite uma comparação mais direta dos perfis de CMM com o perfil de densidade de carga ao longo do canal do transistor. Usando o esquema proposto, esses perfis foram medidos e comparados com o esperado com base no modelo ambipolar. Em geral os perfis de densidade de carga obtidos concordam bem com o modelo, usando apenas um único parâmetro global ajustável, exceto muito próximo do eletrodo de dreno e no regime de saturação profunda, quando os experimentos apresentam um artefato devido à eletro-absorção e não permitem uma comparação precisa com o modelo. Portanto, espera-se que esta Tese tenha contribuído para o avanço de técnicas de caracterização da distribuição de carga em OFETs, e assim melhorar o entendimento de seus mecanismos de funcionamento. / This Thesis deals with the study of Organic Field Effect Transistors (OFETs). Understanding the behavior of the accumulated charge along the OFET channel, which is responsible for the electrical conduction process in the device, is of great importance for improving its efficiency or proposing a theoretical model that describes the behavior of the transistor in all its operating regimes. Several studies in the literature investigate the electric field in the semiconductor layer of the transistor (along the channel) generated by the charge accumulation, but none investigates the field in the OFET dielectric layer, which is directly proportional to the charge accumulated in the channel. The electric field in the dielectric layer of the device was initially investigated by Sum-Frequency Generation (SFG) vibrational spectroscopy. SFG spectra obtained in the polarized devices exhibited a band at ~ 1720 cm-1, due to the carbonyl group of the organic dielectric layer (PMMA - poly (methyl methacrylate)), whose amplitude was proportional to the applied gate voltage, indicating that these polar groups were oriented by the intense electric field in the device. This field-induced SFG signal may be due to two contributions, a second order non-linear term (due to molecular reorientation) and a third order term (interaction between the optical fields and the static field in the material volume). We observed an almost complete reduction of the SFG signal at high temperatures (close to the Tg of the dielectric polymer), indicating that the molecular reorientation mechanism is responsible for the generated SFG signal. Preliminary SFG microscopy measurements were performed to map this SFG signal along the channel of OFET fabricated with N2200 (semiconductor) and PMMA (dielectric) polymers. The results demonstrate the variation of the accumulated charge density along the channel when the device is polarized and close to saturation. Using Charge Modulation Microscopy (CMM), which is another noninvasive method to investigate the accumulation of charges in an operating device, we mapped the charge distribution in the channel of these OFETs with high spatial resolution (sub-micrometer). In addition, a simulation of the expected charge density and CMM profiles was performed using an ambipolar model for OFETs. Based on these simulations, we proposed a square-wave modulation of the OFET, which allows a more direct comparison of the CMM profiles with the charge density profile. Using the proposed scheme, these profiles along the transistor channel were measured and compared with those expected from the ambipolar model. In general, the obtained charge density profiles agree well with the model, using only a single global adjustable parameter, except very close to the drain electrode and in the deep saturation regime, when the experiments have an artifact due to the electro-absorption and do not allow a precise comparison with the model. Therefore, it is expected that this Thesis has contributed to the advancement of techniques to characterize the charge distribution in OFETs, and thus improve the understanding of its operating mechanisms. Keywords: Field-effect transistors. Organic electronics. Nonlinear optics. Sum-frequency generation. Polarization of dielectrics. Charge modulation microscopy.

Alguns aspectos acerca da adsorção de alcanotióis e bases nitrogenadas em ouro via espectroscopia não linear e microscopia de tunelamento de elétrons / Some aspects concerning the adsorption of alkanethiols and uracil derivates on Au via nonlinear spectroscopy and scanning tunneling microscopy

Aguiar, Hilton Barbosa de 15 February 2007 (has links)
Estudos de interface têm presenciado um recente crescimento devido as novas propriedades físico-químicas, que puderam ser explorados com o advento de técnicas com resolução ao nível molecular/atômico. Dessas técnicas, dois ramos que merecem destaque são as Microscopias de Varredura por Ponta de Prova e Espectroscopias Óticas. Neste trabalho fazemos uso de algumas destas técnicas (o Microscópio de Tunelamento de Elétrons e Espectroscopia Vibracional por Geração de Soma de Freqüências) para estudar a adsorção de moléculas alifáticas e aromáticas em Au. Dois casos são abordados: como a rugosidade do substrato influencia no mecanismo de automontagem de monocamadas de alcanotióis e a automontagem de derivados de uracil em interfaces eletroquímicas. No primeiro caso, mostra-se que a quantidade de defeitos moleculares na monocamada adsorvida e extremamente sensível a rugosidade do substrato utilizado. Unem-se os resultados das técnicas acima aos resultados de sondas eletroquímica para se chegar a um modelo. Também e estudado a dependência das etapas de fisisorção e quimisorção em função da concentração da solução de alcanotiól. Para o segundo caso, um derivado halogenado do uracil (5-fluorouracil), mostra-se como a substituição química na base nitrogenada leva a diferentes mecanismos de formação de monocamadas na interface eletroquímica. Imagens de Microscopia de Tunelamento de Elétrons com resolução atômica e molecular mostram que em densidade de cargas negativas as moléculas estão fisisorvidas, porém não formam estruturas periódicas em contraste com uracil e timina, entretanto em densidades de cargas positivas formam estruturas periódicas quimisorvidas, assim como uracil e timina. E discutido como são diferentes os mecanismos de interação intermolecular: no caso dos alcanotiois preponderando às interações de van der Waals e no caso dos derivados de uracil pelas ligações via pontes de hidrogênio são dominantes. / Interface science has experienced a new rebirth since the development of new probes with atomic/molecular resolution, giving new insights about the physical-chemical properties, which differ substantially from the bulk. Among these techniques, two branches deserve special attention: the Scanning Probe Microscopies and Optical Spectroscopy. In this work, two derivatives of theses techniques (the Scanning Tunnelling Microscopy and Vibrational Spectroscopy by Sum-Frequency Generation) are combined giving new insights about the molecular adsorption onto Au. Two examples are focused: how roughness plays a key role in the structure of self-assembled alkanethiol monolayer and the uracil derivatives self-assembling at electrochemical interfaces. For the former, it has been shown that the amount of defects on the adsorbed monolayer is highly sensitive to substrate roughness. Combining the results of each technique with a well-known electrochemical probe, a physical model is proposed. The physisorbed and chemisorbed states are studied as a function of alkanethiol solution concentration as well. For the later case, the chemical substitution of uracil leads to drastically different results for the physisorbed phase (negative charge densities), compared to uracil and thymine. In the chemisorbed phase (positive charge densities) imaging with molecular resolution is achieved showing a quasi-hexagonal structure, similar to the structure of thymine and uracil. It is discussed what are the main driving forces for the self-assembling mechanism: van der Waal interactions for the alkanethiols and hydrogen bonding for uracil derivatives.

Regarding the Constitution of R.O.C on citizen rights , such as work, sexual autonomy, and privacy, however, such ideas above are all referred to whether the permission of sexual trade is OK or NOT. We will look into some regulations of sexual trade, via bits of Grand justice interpretations, to determine if SOMA would be appropriate now days and if it would defy the principle of proportionality and human rights, from the aspect of the Constitution that ought to secure Human rights. Besides collecting related materials, we will further explain the No.666 Grand justice interpretation by combining some scholars’ researches and opinions and some Concurring opinions, and that would be demonstrated on Chapter 2. Secondly, we’ll analyze whether the legalization of sexual trade would be against the social convention, or whether the definition of public order and good morals is permanent. On chapter 3, we’ll establish the main structure and distinguish those who necessarily receive our interview in line up with the cause, problems and ethics of researching. On Chapter 4, we’ll interview the police officers and sexual traders in person to absorb their opinions on by-then regulations, clampdown, human rights of sexual trade and their recommendations. In the final part of the essay, in addition to proposing our discoveries, we will put forward our suggestions on the revision of by-then sexual trade regulations and evaluate the possibilities of validation of sexual trade. Those who feed on sexual trade mostly are afflicted from enormous economic pressure and the ban on sexual trade of regulations make them institutionally deprived. In order to exert the spirit of the Constitution that ought to secure human rights, we advise the government need to enact appropriate laws and rules focusing on sexual trade behavior to effectively replace the clampdown.

MELHORA NA SIMULAÇÃO DA PRODUTIVIDADE DE ARROZ NO RIO GRANDE DO SUL PELA INTRODUÇÃO DE ARROZ HÍBRIDO NO MODELO SIMULARROZ. / IMPROVING THE SIMULATION OF RICE PRODUCTIVITY IN RIO GRANDE DO SUL BY INTRODUCING HYBRIDS IN THE SIMULARROZ MODEL

Ribas, Giovana Ghisleni 25 February 2016 (has links)
Conselho Nacional de Desenvolvimento Científico e Tecnológico / The importance of hybrid rice is increasing because of its higher potential yield compared to n conventional varieties traditionally sown in southern Brazil. The SimulArroz model is a dynamic deterministic mathematical model that simulates the growth, development and grain yield in rice, but the current version of SimulArroz (version 1.0) does not contain the option for hybrid rice. The objective of this dissertation was to calibrate and evaluate the performance of SimulArroz model in simulating the number of leaves, phenology, dry matter accumulation and grain yield of three hybrid rice cultivars in Rio Grande do Sul State, Brazil. Field experiments were conducted in Santa Maria, and in research stations of the Instituto Rio Grandense do Arroz in Cachoeirinha, Uruguaiana, Santa Vitória do Palmar, Cachoeira do Sul, Bagé and Camaquã. The number of main stem leaves, based on the Haun scale, and phenology, based on the Counce scale, and also, plant samples were collected in Santa Maria and Cachoeirinha to determine the dry matter of shoots, leaves, culms, senescent leaves and grain yield. The SimulArroz model is calibrated and evaluated to simulate the number of leaves on the main stem, represented by Haun Stage, phenology, the total dry matter above ground, leaves, stems, senescent leaves and grain yield at 13 % moisture of three hybrid rice cultivars in Rio Grande do Sul. / O arroz híbrido vem ganhando importância por apresentar um potencial produtivo maior do que as cultivares convencionais tradicionalmente semeadas no Sul do Brasil. O modelo SimulArroz é um modelo matemático dinâmico determinístico que simula o crescimento, o desenvolvimento e a produtividade de grãos na cultura do arroz, no entanto a versão atual do SimulArroz (versão 1.0) não contém a opção de simulção para arroz híbrido. Assim, o objetivo nesta dissertação foi calibrar e avaliar o desempenho do modelo SimulArroz em simular o número de folhas, fenologia, o acúmulo de matéria seca e a produtividade de três cultivares de arroz híbrido no Rio Grande do Sul. Foram conduzidos experimentos de campo em Santa Maria, e nas estações regionais de pesquisa do Instituto Rio Grandense do Arroz de Cachoeirinha, Uruguaiana, Santa Vitória do Palmar, Cachoeira do Sul, Bagé e Camaquã. Foram determinados o número de folhas do colmo principal através da escala da Haun e a fenologia conforme a escala de Counce, e também, foram realizadas amostragens de plantas em Santa Maria e Cachoeirinha para determinar a matéria seca total da parte aérea, de folhas, de colmos, de folhas senescentes e produtividade de grãos. O modelo SimulArroz está calibrado e avaliado para simular o número de folhas no colmo principal, representado pelo Estádio de Haun, a fenologia, a matéria seca total da parte aérea, de folhas, de colmos, de folhas senescentes e a produtividade de grãos a 13% de umidade de três híbridos de arroz irrigado no Rio Grande do Sul.

Haplós : towards technologies for, and applications of, somaesthetics

Maranan, Diego Silang January 2017 (has links)
How can vibrotactile stimuli be used to create a technology-mediated somatic learning experience? This question motivates this practice-based research, which explores how the Feldenkrais Method and cognate neuroscience research can be applied to technology design. Supported by somaesthetic philosophy, soma-based design theories, and a critical acknowledgement of the socially-inflected body, the research develops a systematic method grounded in first- and third-person accounts of embodied experience to inform the creation and evaluation of design of Haplós, a wearable, user-customisable, remote-controlled technology that plays methodically composed vibrotactile patterns on the skin in order to facilitate body awareness—the major outcome of this research and a significant contribution to soma-based creative work. The research also contributes to design theory and somatic practice by developing the notion of a somatic learning affordance, which emerged during course of the research and which describes the capacity of a material object to facilitate somatic learning. Two interdisciplinary collaborations involving Haplós contribute to additional fields and disciplines. In partnership with experimental psychologists, Haplós was used in a randomised controlled study that contributes to cognitive psychology by showing that vibrotactile compositions can reduce, with statistical significance, intrusive food-related thoughts. Haplós was also used in Bisensorial, an award-winning, collaboratively developed proof-of-concept of a neuroadaptive vibroacoustic therapeutic device that uses music and vibrotactile stimuli to induce desired mental states. Finally, this research contributes to cognitive science and embodied philosophy by advancing a neuroscientific understanding of vibrotactile somaesthetics, a novel extension of somaesthetic philosophy.

Constantes de acoplamento de vértices com mésons estranhos e charmosos usando as regras de soma da QCD / Coupling constants of vertices with strange and charming mesons using the QCD sum rules

Bruno Osório Rodrigues 12 March 2014 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Neste trabalho, foram calculados os fatores de forma e as constantes de acoplamento dos vértices mesônicos J/ψ DsDs, J/ψ Ds*Ds e J/ψ Ds*Ds*usando a técnica das regras de soma da QCD (RSQCD) até a ordem 5 da OPE. Estes três vértices estão envolvidos em algumas das numerosas hipóteses que tentam explicar a estrutura interna de alguns mésons charmosos exóticos que começaram a ser observados a partir de 2003. Tais mésons não se encaixam no espectro do charmonium e/ou apresentam números quânticos exóticos dentro do modelo CQM (constituent quark model). Um exemplo é o méson Y(4140), cujo decaimento observado é no par J/ψφ enquanto o esperado seria que tivesse decaimento predominante em mésons com open charm, devido à sua massa. Uma das propostas para se entender este méson consiste em estudá-lo como um estado molecular Ds*ar{D}s*, de modo que seu decaimento seria Y(4140) → Ds* ar{D}s* → J/ψφ. Neste processo, aparecerão os vértices de interação estudados neste trabalho, de maneira que o conhecimento mais preciso de seus fatores de forma e de suas constantes de acoplamento pode beneficiar a compreensão sobre a constituição fundamental do Y(4140) assim como a de outros novos estados como o X(4350), Y(4274) e Y(4660) por exemplo. Foram considerados neste trabalho, todos os casos off-shell possíveis para cada um dos três vértices, obtendo assim dois fatores de forma distintos para o vértice J/ψ DsDs, três para o vértice J/ψ Ds*Ds e dois para o vértice J/ψ Ds* Ds*. Nestes três vértices, os fatores de forma para o caso J/ψ off-shell foram bem ajustados por curvas monopolares enquanto os casos Ds e Ds* foram ajustados por curvas exponenciais, o que está de acordo com o comportamento encontrado em trabalhos anteriores do grupo. Os cálculos das constantes de acoplamento tiveram como resultados: g_{J/ψ Ds Ds} = 5.98^{+0.67}_{ -0.58}, g_{J/ψ D*s Ds} = 4.30_{+0.41}^{-0.35}GeV^{-1} e g_{J/ψ Ds* Ds*} = 7.47^{+1.04}_{-0.71}, resultados estes que estão compatíveis com os trabalhos anteriores que utilizaram as RSQCD para o cálculo das constantes de acoplamento dos vértices J/ψ D(*)D(*). / In this work, the form factors and coupling constants of the meson vertices J/ψ DsDs, J/ψ Ds*Ds and J/ψ Ds*Ds* have been calculated with the QCD sum rule (QCDSR) technique up to dimension 5 of the operator product expansion (OPE). These three vertices are involved in some of the numerous hypotheses that attempt to explain the internal structure of some exotic charmed mesons which began to be observed since 2003. Such mesons do not fit in the charmonium spectrum and/or have exotic quantum numbers within the CQM (constituent quark model). An example is the Y(4140) meson, which decays in the pair J/ψφ while the expected would be a dominant decay in open charm mesons. One of the proposals to understand this meson is to study it as a molecular state Ds*{D}s*, so it would decay as Y(4140)→ Ds* {D}s* → J/ψφ.In this process, the vertices studied in this work will appear, so the more accurate knowledge of their form factors and their coupling constants can benefit our understanding of the fundamental constitution of the Y(4140) as well as other new states as the X(4350), Y(4274) and Y (4660) eg. In this study all possible off-shell cases for each of these three vertices were considered, thus obtaining two different form factors for the vertex J/ψ DsDs, three for the vertex J/ψ Ds*Ds and two for the vertex J/ψ Ds* Ds*. In these three vertices, the form factors for the J/ψ off-shell case were well fitted by monopolar curves, while the Ds and Ds* off-shell cases were well fitted by exponential curves which is in agreement with the behavior found in previous work of the group. The calculations of the coupling constants leaded to the following results: g_{J/ψ Ds Ds} = 5.98^{+0.67}_{-0.58}, g_{J/ψ Ds* Ds} = 4.30^{+0.41}_{-0.35}GeV^{-1} and g_{J/ψ Ds* Ds*} = 7.47^{+1.04}_{-0.71}, these results are compatible with previous QCDSR works for the non strange vertices J/ψD(*)D(*).
