description: [Abridged] Theoretical and numerical studies of star formation have shown that magnetic field (B) has a strong influence on both disk formation and fragmentation; even a relatively low B can prevent these processes. However, very few studies investigated the combined effects of B and turbulence. We study the effects of turbulence in magnetized core collapse, focusing on the magnetic diffusion, the orientation of the angular momentum (J) of the protostellar core, and on its consequences on disk formation, fragmentation and outflows. We perform 3D, AMR, MHD simulations of magnetically supercritical collapsing dense cores of 5 Msun using the MHD code RAMSES. A turbulent velocity field is imposed as initial conditions, characterised by a Kolmogorov power spectrum. Different levels of turbulence and magnetization are investigated, as well as 3 realisations for the turbulent velocity field. Magnetic diffusion, orientation of the rotation axis with respect to B, transport of J, disk formation, fragmentation and outflows formation are studied. The turbulent velocity field imposed as initial conditions contains a non-zero J, responsible for a misalignment of the rotation axis. Turbulence is also responsible for an effective turbulent diffusivity in the vicinity of the core. Both effects are responsible for a significant decrease of the magnetic braking, and facilitate the formation of early massive disks for not too high magnetization. Fragmentation can occur even with mu ~ 5 at late time in contrast with 1 Msun cores for which fragmentation is prevented for such values of mu. Slow asymmetric outflows are launched. They carry a mass which is comparable to the mass within the core. Because of misalignment and turbulent diffusion, massive disk formation is possible though their mass and size are still reduced compared to the hydrodynamical case. We find that for mu >= 5, fragmentation can happen.

description: Women of NASA (© 2017 The LEGO Group) é um LEGO que tem, como qualquer outro, uma finalidade lúdica, mas, pelo seu enfoque de cariz científico – Mulheres na Ciência – e pelos casos reais a que se reporta, adquire um potencial educativo significativo na (re)construção da imagem de cientista. Retrata quatro mulheres cientistas que se destacaram pela atividade pioneira exercida na NASA: Margaret Hamilton, Sally Ride, Nancy Roman e Mae Jemison. O LEGO consiste na construção das quatro figuras femininas e de cenários ilustrativos do contexto de trabalho. É acompanhado de um pequeno livro que contém uma curta biografia de cada uma das cientistas. Sendo definido como problema de investigação – Qual é o impacto da exploração do LEGO “Women of NASA” na (re)construção da imagem de cientistas de alunos do 3.º Ciclo do Ensino Básico? – estruturou-se uma atividade de aprendizagem de lápis e papel, segundo um paradigma epistemológico-didático de cariz autossocioconstrutivista, que inclui a consciencialização das ideias prévias dos alunos acerca das pessoas que são cientistas, da construção e interpretação do LEGO, da interpretação das biografias e da reflexão acerca das ideias iniciais e finais, num contexto educativo reflexivo, dialógico e cooperativo. Envolveu 40 alunos de duas turmas de Físico-Química do 7.º ano de escolaridade. As perguntas de cariz reflexivo, que integraram a atividade de aprendizagem, assumiram uma dupla função: pedagógica e investigativa. A análise de conteúdo mostrou a reconstrução das ideias estereotipadas de cientistas, perfilhadas inicialmente pelos alunos.

description: Expansion dynamics at the yoctosecond timescale affect the evolution of the quark gluon plasma (QGP) created in heavy ion collisions. We show how these dynamics are accessible through Hanbury Brown and Twiss (HBT) intensity interferometry of direct photons emitted from the interior of the QGP. A detector placed close to the beam axis is particularly sensitive to early polar momentum anisotropies of the QGP. Observing a modification of the HBT signal at the proposed FoCal detector of the LHC ALICE experiment would allow to measure the isotropization time of the plasma and could provide first experimental evidence for photon double pulses at the yoctosecond timescale.

description: De modo a motivar os alunos para o ensino das Ciências, os professores devem tornar as suas práticas pedagógicas mais ativas e inovadoras, socorrendo-se de variados recursos didáticos. Um recurso promotor da construção de conhecimentos, por parte dos alunos, é o Trabalho Prático de cariz Investigativo (TI). Partindo desta premissa, efetuou-se um estudo, no decurso da Prática de Ensino Supervisionada de um Mestrado em Ensino do 1.º CEB e de Mat/CN no 2.º CEB, com uma turma de 18 alunos, do 6.º ano. O percurso investigativo iniciou-se com a formulação da questão: quais as competências que as atividades práticas de cariz investigativo, no âmbito da educação em ciências, permitem desenvolver nos alunos do 2.º CEB? Pretendeu-se, assim, averiguar se o TI permite desenvolver competências de índole concetual, processual e atitudinal, que sejam promotoras de aprendizagens significativas. Neste sentido, foi utilizada uma metodologia qualitativa, com orientação interpretativa e descritiva, utilizando-se como estratégia investigativa o estudo de caso. Este iniciou-se com a fase de diagnóstico, aplicando-se um inquérito por questionário aos alunos, para perceber a sua motivação e modo de aprender ciências, bem como uma entrevista semiestruturada à professora, para averiguar quais os recursos e estratégias utilizadas; posteriormente, foi realizada uma intervenção pedagógica, com a elaboração de atividades investigativas e, por fim, de modo a proceder-se à avaliação do processo, foi efetuada uma entrevista semiestruturada aos alunos. Os dados recolhidos foram analisados e triangulados e, apesar de este estudo ter sido realizado em período pandémico, com certas restrições à realização de atividades práticas nas escolas, os resultados permitiram perceber as inúmeras potencialidades do trabalho prático de índole investigativo para a Educação em Ciências, nomeadamente, ao nível do desenvolvimento da autonomia, do trabalho colaborativo, do pensamento crítico e criativo, da resolução de problemas, entre outro tipo de competências.

description: Acellular slime mould Physarum polycephalum is a monstrously large single cell visible by an unaided eye. It shows sophisticated behavioural traits in foraging for nutrients and developing an optimal transport network of protoplasmic tubes spanning sources of nutrients. The slime mould sufficiently approximates man-made transport networks on a flat substrate. Does slime mould imitate man-made transport networks on three-dimensional terrain as well as it does on a flat substrate? We simplified the problem to approximation of a single transport route. In laboratory experiments with 3D Nylon terrains of USA and Germany we imitated development of route 20, the longest road in USA, and autobahn 7, the longest national motorway in Europe. We found that slime mould builds longer transport routes on 3D terrains, comparing to flat agar plates yet sufficiently approximates man-made transport routes studied. We discuss how nutrients placed in destination sites affect performance of slime mould, how the mould navigates around elevations, and offer an automaton model of slime mould which might explain variability of the protoplasmic routes constructed. We also display results of scoping experiments with slime mould on 3D terrains of Russia and United Kingdom.

description: O Estudo de Aula tem sido usado na formação contínua de professores um pouco por todo o mundo. Contudo, a sua utilização na formação inicial de professores ainda é pouco estudada. Em Portugal, têm tido lugar algumas investigações no ensino das ciências sobre a implementação do Estudo de Aula na formação inicial, sendo neste âmbito que o nosso trabalho se enquadra. Os estudos têm demonstrado potencialidades do processo no desenvolvimento do conhecimento pedagógico de conteúdo (PCK) dos futuros professores, na promoção dos processos colaborativos, na mudança de foco das ações do (futuro) professor para as atividades e aprendizagens dos alunos. São ainda reportadas aprendizagens nos professores cooperantes participantes no processo. O Content Represention Knowledge (CoRe), que inicialmente foi mais usado para explorar o PCK de professores experientes, tem vindo a ser utilizado, no âmbito da formação inicial de professores, com o objetivo de promover o desenvolvimento do PCK. O CoRe permite uma maior integração da teoria e da prática, aceder a aspetos mais tácitos dos professores cooperantes e assim exibir conhecimento pedagógico e didático muitas vezes não explicitado. Investigamos, utilizando uma análise narrativa, o efeito do uso do CoRe num Estudo de Aula centrado no sistema cardiovascular desenvolvido no âmbito da Prática de Ensino Supervisionada no 2.º CEB de uma escola de Lisboa, centrando a nossa análise no envolvimento da Professora Cooperante. Apresentamos evidências que mostram um processo genuinamente colaborativo envolvendo todos os participantes. A professora cooperante mostra ganhos no entendimento do processo formativo relativamente à sua prática usual.

Application of minority stress and suicide models in bisexual+ versus gay/lesbian young adults
Creators: name: Chang, Cindy
Publisher: name: No Publisher Supplied
Year: 2022

description: Sexual minority (e.g., lesbian, gay, bisexual, pansexual, queer) young adults are at increased risk for suicidal ideation (SI) compared to heterosexual young adults. Several frameworks have been proposed to explain the development of suicide risk, including the Interpersonal Theory of Suicide (IPTS) among the general population and the Minority Stress Model among sexual minority people. However, few studies have examined these frameworks in conjunction, and there is a dearth of research examining risk factors for suicide in bisexual+ individuals. This study addresses these gaps in the literature by examining multiple frameworks for understanding suicide risk in sexual minority young adults, as well as extending this research to the understudied bisexual+ subgroup. A total of 794 sexual minority young adults (49.9% bisexual+ and 50.1% gay/lesbian) completed an online survey at baseline, at one-month follow-up, and at two-month follow-up assessing constructs related to IPTS and the minority stress model as well as SI. In the full sample, all types of minority stress at baseline were significantly associated with SI at two-month follow-up via perceived burdensomeness (PB) and thwarted belongingness (TB) at one-month follow-up. In the bisexual+ subsample, all bisexual-specific minority stressors at baseline were also significantly associated with SI at two-month follow-up via PB at one-month follow-up; internalized binegativity was associated with SI via both PB and TB. However, the effects became non-significant when controlling for previous levels of the mediators and outcome variables. Sexual identity (bisexual+ versus gay/lesbian) did not moderate any associations or indirect effects among the full sample. Findings provide preliminary support for the relevance of minority stress and IPTS for understanding the development of suicide risk among sexual minority young adults, and they highlight the importance of targeting these factors to reduce suicide in this high disparity population.

description: In the exoplanetary era, the Kepler spacecraft is causing a revolution by discovering thousands of new planet candidates. However, a follow up program is needed in order to reject false candidates and to fully characterize the bona-fide exoplanets. Our main aims are: 1./ Detect and analyze close companions inside the typical Kepler PSF to study if they are the responsible of the dim in the Kepler light curves, 2./ Study the change in the stellar and planetary parameters due to the presence of an unresolved object, 3./ Help to validate those Kepler Objects of Interest that do not present any object inside the Kepler PSF and 4./ Study the multiplicity rate in planet host candidates. Such a large sample of observed planet host candidates allows us to do statistics about the presence of close (visual or bounded) companions to the harboring star. We present here Lucky Imaging observations for a total amount of 98 Kepler Objects of Interest. This technique is based on the acquisition of thousands of very short exposure time images. Then, a selection and combination of a small amount of the best quality frames provides a high resolution image with objects having a 0.1 arcsec PSF. We applied this technique to carry out observations in the Sloan i and Sloan z filters of our Kepler candidates. We find blended objects inside the Kepler PSF for a significant percentage of KOIs. On one hand, only 58.2% of the hosts do not present any object within 6 arcsec. On the other hand, we have found 19 companions closer than 3 arcsec in 17 KOIs. According to their magnitudes and i-z color, 8 of them could be physically bounded to the host star.

description: Τα τελευταία χρόνια οι φαρμακευτικές πωλήσεις στην Ελλάδα έχουν υποστεί σημαντική μείωση. Συνέπεια αυτής εξέλιξης αποτελεί ο σκεπτικισμός με τον οποίο αντιμετωπίζουν μεγάλες επιχειρήσεις της φαρμακευτικής βιομηχανίας μελλοντικές τους επενδύσεις. Η ανάγκη για μακροπρόθεσμες και ακριβείς προβλέψεις ως εργαλείο στρατηγικού προγραμματισμού αυξάνει. Στόχος της παρούσας διπλωματικής εργασίας αποτελεί ο σχεδιασμός ενός μοντέλου μακροπρόθεσμης (πολλών βημάτων μπροστά) πρόβλεψης για τις συνολικές πωλήσεις της φαρμακευτικής βιομηχανίας. Προς αυτήν την κατεύθυνση διερευνούμε μεθοδολογίες από τον τομέα της Τεχνητής Νοημοσύνης. Τα Εμπρόσθια Νευρωνικά Δίκτυα και το Προσαρμοστικό Νεύρο-Ασαφές Σύστημα Εξαγωγής Συμπεράσματος υιοθετήθηκαν. Οι συγκεκριμένες τεχνικές έχουν αποδείξει την ανωτερότητά τους έναντι των στατιστικών μεθόδων σε προβλήματα πρόβλεψης ενός βήματος μπροστά. Ωστόσο, η μακροπρόθεσμη πρόβλεψη αποτελεί πρόκληση για τους ερευνητές. Η υλοποίηση των μοντέλων βασίστηκε στα δεδομένα των τελευταίων 14 ετών, τα οποία διατίθενται στην ιστοσελίδα του Εθνικού Οργανισμού Φαρμάκων. Τα αποτελέσματα των δύο μεθοδολογιών συγκρίθηκαν και αξιολογήθηκαν με στόχο τον εντοπισμό του κατάλληλου μοντέλου για το συγκεκριμένο πρόβλημα.
Singleton deformation of higher-spin theory and the phase structure of the three-dimensional O(N) vector model

description: We consider a singleton deformation of the AdS4 higher-spin theory dual to the three-dimensional O(N) vector model. The singleton couples to the higher-spin multiplet only through a marginal boundary interaction. We argue that the effect of such a deformation is to shift N to N+1 in both sides of the holographic correspondance and we show how the gap equations of the three-dimensional O(N) vector model arise from the higher-spin theory. The singleton deformation breaks higher-spin symmetry and gives rise to the well-known 1/N anomalous dimensions of the boundary theory.

Perspectives on sexual minority mental health in India
Creators: name: Kulshreshtha, Rupali
Publisher: name: No Publisher Supplied
Year: 2022

description: A higher mental health burden for non-heterosexual individuals has been consistently demonstrated in the literature, though most of this research has focused on high income countries where homosexuality is considered more socially acceptable (Blondeel et al., 2016; Chakraborty et. al, 2011; Kohut et. al, 2013). The decriminalization of homosexuality in India in 2018 signifies an important legal and social change for sexual minority Indians. However, research on sexual minority adults in India has largely focused on HIV status and risk rather than the experiences and specific mental health needs of this population. Similarly, existing research on mental health treatment in India is limited and largely based on task-shifting to less qualified healthcare workers, primary care integration, and availability of resources.This study aims to contribute to this limited body of research by developing an understanding of the specific mental health needs and experiences of sexual minority adults in Delhi, NCR. Additionally, this study examines perceptions and training gaps of the mental healthcare providers (MHPs) working with sexual minority individuals. An interpretative phenomenological analysis (IPA) approach was used to analyze data from two virtual focus groups – one with sexual minority (SM) adults (n = 8), and the second with mental healthcare providers (n = 7). Six superordinate themes emerged from each focus group discussion. For the SM group, these included the consequences of coming out, the psychological impact of queerness, mental health care experiences, experiences of the self and identity, ecological experiences in the Indian context, and the arc of resilience. For the MHP group these included presenting problems, barriers to care, ecological experiences in the Indian context, provider training issues, therapist growth, and responsibility and accountability. These findings present several implications for understanding the unique experiences and mental health needs of urban sexual minority Indians as well as recommendations for the improvement of MHP training. Strengths and limitations of the current study are discussed and suggestions for further research and policy changes are presented.

Year: 2023
Subjects: Higher education

description: This research project was designed to obtain a greater understanding of the key factors that underpin the organisational and academic quality of non self-accrediting institutions (NSAis), and thus to assist them to navigate the Australian higher education regulatory framework. To support the project an ethnographic study was undertaken within the higher education community of practice. The findings of the study revealed significant issues that affect the academic, cultural, physical, financial and regulatory constructs of the Australian non self-accrediting higher education sector. From these findings a CD-ROM was developed detailing a method for guiding NSAis to prepare for, and maintain compliance with, regulatory requirements associated with gaining approval to deliver higher education courses in Australia. The CD-ROM fills a gap of advice and guidance available to NSAis when considering whether to enter the Australian higher education sector.

description: Este artigo reporta um estudo que procura compreender as perceções de futuros professores do ensino básico sobre a utilização de tecnologia digital na exploração da matemática fora da sala de aula. Optou-se por uma abordagem qualitativa e interpretativa, sendo os dados recolhidos por meio da observação participante, questionários e registos fotográficos. Participaram neste estudo quarenta e oito futuros professores, inscritos numa unidade curricular de Didática da Matemática, que utilizaram a aplicação MathCityMap na realização de um trilho matemático na cidade de Viana do Castelo. Os resultados mostram que valorizaram a experiência, tendo tido a oportunidade de resolver tarefas em contexto real, através de um trabalho cooperativo, promotor do pensamento crítico e do estabelecimento de conexões matemáticas. Consideraram a aplicação motivadora, de fácil utilização e mais interativa do que a versão em papel, referindo ainda o seu contributo para o envolvimento dos alunos numa aprendizagem ativa, o desenvolvimento da orientação espacial e da autonomia. Quanto às limitações, os participantes destacaram a possível falta de acesso à rede Wi-Fi; o facto de alunos mais jovens normalmente não possuírem smartphones; e, em termos de tarefas, a limitação dos formatos de resposta a um valor exato, aproximado ou escolha múltipla.

description: O presente estudo envolveu 25 alunos (2 turmas) e teve a finalidade de desenvolver a consciencialização para o bem-estar animal em alunos do 5.º ano de escolaridade. Os objetivos gerais foram: (i) identificar as conceções que os alunos possuem acerca de diversas situações que envolvam a relação entre o ser humano e os animais; (ii) desenvolver o pensamento crítico dos alunos acerca do bem-estar animal, através de atividades de discussão acerca de diferentes situações envolvendo os animais e com relevância na sociedade; (iii) desenvolver a sua consciencialização acerca do bem-estar animal, através do reconhecimento das ações negativas que se exercem sobre os animais. Metodologicamente teve uma natureza mista de teor quantitativo e qualitativo, com procedimentos próximos de Investigação-Ação. A técnica principal de recolha de dados foi um questionário com questões de natureza fechada e aberta, administrado antes e depois de um conjunto de sessões (plano de intervenção) para as quais foram construídos recursos que visaram trabalhar a utilização dos animais para diversos fins humanos. Este plano, com a duração de dois meses, foi desenvolvido em uma das turmas, sendo a outra o grupo de controlo. No tratamento dos dados quantitativos utilizou-se estatística inferencial com recurso ao SPSS, tendo os dados qualitativos sido submetidos a análise de conteúdo e categorizadas as respostas. Os resultados do estudo indicam que os alunos desenvolveram uma maior consciencialização acerca do bem-estar animal e o seu pensamento crítico, dado que foram capazes de identificar situações de injustiça envolvendo os animais e de argumentar contra elas.

description: We present Herschel spatially resolved images of the debris disc orbiting the subgiant Kappa CrB. Not only are these the first resolved images of a debris disc orbiting a subgiant, but Kappa CrB is a rare example of an intermediate mass star where a detailed study of the structure of the planetary system can be made, including both planets and planetesimal belt(s). The only way to discover planets around such stars using the radial velocity technique is to observe 'retired' A stars, which are cooler and slower rotators compared to their main-sequence counterparts. A planetary companion has already been detected orbiting the subgiant Kappa CrB, with revised parameters of m sin i = 2.1MJ and apl = 2.8AU (Johnson et al. 2008a). We present additional Keck I HIRES radial velocity measurements that provide evidence for a second planetary companion, alongside Keck II AO imaging that places an upper limit on the mass of this companion. Modelling of our Herschel images shows that the dust is broadly distributed, but cannot distinguish between a single wide belt (from 20 to 220AU) or two narrow dust belts (at around 40 and 165AU). Given the existence of a second planetary companion beyond approximately 3AU it is possible that the absence of dust within approximately 20AU is caused by dynamical depletion, although the observations are not inconsistent with depletion of these regions by collisional erosion, which occurs at higher rates closer to the star.

"See amazing" in the classroom: evaluating opportunities for educating about autism in early childhood classrooms

Year: 2022

description: In 2015, Sesame Workshop released See Amazing in All Children, an initiative designed to reduce stigma about autism with resources for young children and their caregivers. This paper explores early childhood teachers’ impressions of materials from this initiative, focusing on its potential use in the classroom. Twelve teachers, stratified by teaching position (general education or special education) and experience with autism (low level of experience or high level of experience), participated in interviews and viewed materials from See Amazing. As the project was designed as an exploratory needs assessment, a grounded theory approach was used to investigate common themes among participants. Participants believed that teaching young children about autism was a valuable practice and identified developmental traits that make early childhood a prime opportunity for doing so. Teachers were enthusiastic about the See Amazing materials and praised the way See Amazing presented autism to young students in a developmentally appropriate way. They generally expressed interest in integrating components into their classrooms and indicated the types of support they would require. Teachers also identified potential challenges or barriers to implementation. Special education teachers and those with more than three years of experience demonstrated deeper pre-existing knowledge and were more likely to have previous experience teaching their students about autism. Teachers with less experience, especially those in general education settings, showed foundational knowledge, but were less confident about teaching their students about autism without further guidance. Overall, this study provides preliminary support for the expansion of See Amazing and related teacher support materials for greater use in early childhood classrooms to teach typical students about autism.

description: Η δρομολόγηση οχημάτων συλλογής αστικών αποβλήτων σε ένα αστικό δίκτυο
διαχείρισης απορριμμάτων είναι ένα πρόβλημα που έχει απασχολήσει τα τελευταία
χρόνια την επιστημονική κοινότητα, τόσο για τους πολίτες μεμονωμένα όσο και για
την πολιτεία συνολικά.
Στην παρούσα διατριβή, προτείνουμε μια μεθοδολογία βελτιστοποίησης της
συλλογής αστικών αποβλήτων σε μία αστική περιοχή που στόχος της είναι η μείωση του κόστους αποκομιδής για την πολιτεία με την καλύτερη δρομολόγηση των απορριμματοφόρων. Τα μοντέλα που προτείνουμε βασίζονται στον μικτό ακέραιο γραμμικό προγραμματισμό. Η εφαρμογή τους αναμένουμε να δώσει αρκετά καλά αποτελέσματα, τα οποία μπορούν να εφαρμοστούν στην πράξη δίνοντας μεγάλη ακρίβεια και βελτιώνοντας πολύ την αρχική κατάσταση.

description: We demonstrate a narrow line, fiber loop laser using Erbium-doped fiber as the gain material, stabilized by using a microsphere as a transmissive frequency selective element. Stable lasing with a linewidth of 170 kHz is observed, limited by the experimental spectral resolution. A linear increase in output power and a red-shift of the lasing mode were also observed with increasing pump power. Its potential application is also discussed.

description: Σε μια καταναλωτική κοινωνία όπου παρατηρείτε έντονη ανταγωνιστικότητα καθώς και επιλεκτική αγορά προϊόντων ο τομές της διαχείρισης της εφοδιαστικής αλυσίδας είναι σημαντικός για την βιωσιμότητα μια εταιρίας. Στην παρούσα διπλωματική εργασία ασχολούμαστε με το ανοιχτό κλειστό πρόβλημα δρομολόγησης οχημάτων ( open close vehicle routing problem ). Το συγκεκριμένο πρόβλημα εφαρμόζεται κυρίως από εταιρίες στις οποίες ο αριθμός των ιδιόκτητων οχημάτων, δεν επαρκεί για την συνολική κάλυψη της ζήτησης. Σκοπός του προβλήματος είναι η εύρεση μονοπατιών ελάχιστου κόστους. Όλα τα οχήματα ξεκινώντας από την αποθήκη προσπαθούν να καλύψουν την συνολική ζήτηση, χωρίς να παραβιάζονται οι περιορισμοί της χωρητικότητας καθώς και της μέγιστης απόσταση που μπορούν να διανύσουν. Η ιδιαιτερότητα του συγκεκριμένου προβλήματος είναι, τα ενοικιαζόμενα οχήματα να μην έχουν τη δυνατότητα να επιστρέψουν στην αποθήκη.
Αρχικά για την εύρεση μια αρχικής εφικτής λύσης χρησιμοποιήθηκε ο αλγόριθμος του GRASP και στην συνέχεια, για την βελτίωση της, εφαρμόστηκε ο αλγόριθμος Ant Colony Optimization, σε συνδυασμό με τρεις αλγόριθμους τοπικής αναζήτησης (2-opt , 1-1 exchange, 1-0 relocate). Ο αλγόριθμος εφαρμόστηκε σε γνωστά παράδειγμα από την βιβλιογραφία όπου και συγκριθήκαν τα αποτελέσματα τους. Για την επίλυση του συγκεκριμένου προβλήματος αναπτύχθηκε αλγόριθμος σε περιβάλλον matlab.

description: The nitrogen-vacancy centre (NV) has drawn much attention for over a decade, yet detailed knowledge of the photophysics needs to be established. Under typical conditions, the NV can have two stable charge states, negative (NV-) or neutral (NV0), with photo induced interconversion of these two states. Here, we present detailed studies of the ionization dynamics of single NV centres in bulk diamond at room temperature during illumination in dependence of the excitation wavelength and power. We apply a recent method which allows us to directly measure the charge state of a single NV centre, and observe its temporal evolution. Results of this work are the steady state NV- population, which was found to be always < 75% for 450 to 610 nm excitation wavelength, the relative absorption cross-section of NV- for 540 to 610 nm, and the energy of the NV- ground state of 2.6 eV below the conduction band. These results will help to further understand the photo-physics of the NV centre.
