title: Institutionelle Rahmenbedingungen der Ermöglichung und Förderung einer professionellen Ausübung des Lehrberufs an deutschen Regelschulen
Creators: name: Dolshenko, Nick

description: Die vorliegende Arbeit setzt an dem Gedanken an, dass sich die Professionalität von Lehrpersonen nicht allein schon aus dem bloßen beruflichen Agieren ergibt, sondern diese zunächst angeeignet und gepflegt werden muss. In der Schulentwicklungs- und Professionsforschung besteht jedoch das Problem, dass nicht ausreichend darüber aufgeklärt ist, inwiefern die Einzelschule als Sozialisationsort die Professionalisierung von Lehrpersonen bedingt. Dieses Problem wurde hier angegangen und es erfolgte der Bestimmungsversuch, ob und wie sich die Professionalisierung fördernde Rahmenbedingung von Einzelschulen bestimmen lassen. Über die Bearbeitung der Literatur zur Professionsforschung im Lehrberuf erfolgten vier zentrale Ergebnisse: Erstens konnte ein innovatives Modell zur Genese eines professionellen Habitus im Kontext vom beruflichen Agieren im Feld der Schule konzipiert werden. Eine zweite Modellkonzeption veranschaulicht die Dynamik zwischen Gelingensfaktoren von Professionalisierung im Lehrberuf. Drittens, erfolgte eine Bewertung der Schulkulturanalyse von Helsper et al. als eine geeignete Methode zur Bestimmung professionalisierungsfördernder Rahmenbedingungen von Schulen mithilfe von Fallstudien. Viertens konnte erörtert werden, warum sich professionelle Praxen im Feld immer fallspezifisch und aus sich selbst heraus bewähren müssen und sich Praxisformen nicht beliebig auf Schulen übertragen oder sich ihnen „überstülpen“ lassen. Indem diese Arbeit veranschaulicht, dass sich die Schule als Sozialisationsort maßgeblich auf die Herausbildung von professionellen oder nicht-professionellen Wahrnehmungs-, Denk- und Handlungsmustern auswirkt, zeigt sie, dass der Zusammenhang von Schulkultur und Professionalisierung in der Professions- und Schulentwicklungsforschung künftig stärker berücksichtigt werden sollte.

description: In this paper, we consider left-invariant para-complex structures on six-dimensional nilpotent Lie groups. A complete list of six-dimensional nilpotent Lie groups that admit para-Kähler structures is obtained, explicit expressions for para-complex structures are found, and curvature properties of associated para-Kähler metrics are investigated. It is shown that paracomplex structures are nilpotent and the corresponding para-Kähler metrics are Ricci-flat.

description: We have developed a method for deriving the distribution of the Milky Way's interstellar medium as a function of longitude, latitude, distance and line-of-sight velocity. This method takes as input maps of reddening as a function of longitude, latitude, and distance and maps of line emission as a function of longitude, latitude, and line-of-sight velocity. We have applied this method to datasets covering much of the Galactic plane. The output of this method correctly reproduces the line-of-sight velocities of high-mass star forming regions with known distances from Reid et al. (2014) and qualitatively agrees with results from the Milky Way kinematics literature. These maps will be useful for measuring flows of gas around the Milky Way's spiral arms and into and out of giant molecular clouds.

Da descolonização inacabada ao limiar da independência

description: O “25 de Abril de 1974” encontrou o território de Timor-Leste numa situação de subdesenvolvimento, apesar das melhorias que, desde a segunda metade da década de 1960, muito por força da pressão internacional, ali haviam sido introduzidas. No entanto, a herança portuguesa revelar-se-ia a vários níveis, serviria de diferenciação dos Timorenses de Leste perante o ocupante e, em larga medida, tem sido incorporada na identidade do novo Estado. A criação de partidos políticos, com a descolonização, por falta de experiência e de verdadeiras elites, conduziu a uma cerrada luta política, que Portugal não conseguiu tutelar e que a Indonésia aproveitou para concretizar um desígnio que, desde a sua formação, animava sobretudo o sector militar. Por sua vez, a Austrália, no imediato, tentou não se comprometer directamente; mas, posteriormente, apoiou a anexação. A retirada de Portugal, sem que o processo de descolonização do território houvesse terminado, e a conjuntura internacional, possibilitaram uma anexação e uma ocupação violentas, contrariadas por uma resistência que surpreendeu o mundo. Portugal conseguiu depois, interna e externamente, manter viva a “Questão de Timor-Leste”, participando simultaneamente em conversações com a Indonésia, sob patrocínio da ONU, que culminaram com o acordo e o referendo de 1999. Entretanto, a diáspora timorense encontrou vários tipos de ajuda em Portugal, para os que ficaram e para os que procuravam outros destinos, sobretudo a Austrália. A construção do novo país tem contado com uma significativa ajuda oficial, multilateral e bilateral, da antiga Metrópole, mas também de organismos autónomos e da iniciativa privada.

Nonlinear model of ice surface softening during friction

description: The ice surface softening during friction is shown as a result of spontaneous appearance of shear strain caused by external supercritical heating. This transformation is described by the Kelvin-Voigt equation for viscoelastic medium, by the relaxation equations of Landau-Khalatnikov-type and for heat conductivity. The study reveals that the above-named equations formally coincide with the synergetic Lorenz system, where the order parameter is reduced to shear strain, stress acts as the conjugate field, and temperature plays the role of a control parameter. Using the adiabatic approximation, the stationary values of these quantities are derived. The examination of dependence of the relaxed shear modulus on strain explains the ice surface softening according to the first-order transition mechanism. The critical heating rate is proportional to the relaxed value of the ice shear modulus and inversely proportional to its typical value.

description: Physical realizations of the canonical phase measurement for the optical phase are unknown. Single-shot phase estimation, which aims to determine the phase of an optical field in a single shot, is critical in quantum information processing and metrology. Here we present a family of strategies for single-shot phase estimation of coherent states based on adaptive non-Gaussian, photon counting, measurements with coherent displacements that maximize information gain as the measurement progresses, which have higher sensitivities over the best known adaptive Gaussian strategies. To gain understanding about their fundamental characteristics and demonstrate their superior performance, we develop a comprehensive statistical analysis based on the Bayesian optimal design of experiments, which provides a natural description of these non-Gaussian strategies. This mathematical framework, together with numerical analysis and Monte Carlo methods, allows us to determine the asymptotic limits in sensitivity of strategies based on photon counting designed to maximize information gain, which up to now had been a challenging problem. Moreover, we show that these non-Gaussian phase estimation strategies have the same functional form as the canonical phase measurement in the asymptotic limit differing only by a scaling factor, thus providing the highest sensitivity among physically-realizable measurements for single-shot phase estimation of coherent states known to date. This work shines light into the potential of optimized non-Gaussian measurements based on photon counting for optical quantum metrology and phase estimation.

Neon Metin, um periódico clandestino em língua portuguesa editado pela Renetil (1989-1996). Contributos para a história do pré-jornalismo independentista em Timor-Leste
Creators: name: Gomes, Adelino
Publisher: name: Povos e Culturas
Year: 2015

description: A Renetil (Resistência Nacional dos Estudantes Timorenses) concebeu, produziu, editou e distribuiu clandestinamente, durante oito anos, um boletim informativo em língua portuguesa intitulado Neon Metin. O II Encontro de Jornalistas de Língua Portuguesa (Brasília, 1989) chegou a debater, por sua causa, a admissão de Timor-Leste como oitavo membro. Cruzando metodologias quantitativas e qualitativas (inquéritos por questionário, entrevistas pessoais e em grupo e análise documental), reconstitui-se o modo de produção, analisam-se características editoriais do periódico e identificam-se, pela primeira vez, elementos do respectivo “Corpo Redactório”, vários dos quais ocupam hoje lugares de proeminência no Governo, na Assembleia Nacional, no aparelho de Estado, ONG e empresariado. Numa leitura crítica dos exemplares preservados em fontes e arquivos da Resistência e da solidariedade internacional, e recorrendo a critérios e categorias classificativas consagradas na historiografia jornalística portuguesa, surpreendem-se em Neon Metin dispositivos técnicos, critérios editoriais, procedimentos, práticas e constrangimentos que, salvaguardadas circunstâncias e especificidades históricas, tecnológicas e culturais, ecoam: por um lado, a índole jornalística das Gazetas e relações de notícias do periodismo português da Restauração da Independência, das invasões napoleónicas e da guerra civil de 1846-1847 (Tengarrinha, 2013; Sousa, 2008); e, por outro, as “armas de papel” com que jovens portugueses, colaboradores de publicações periódicas clandestinas e do exílio, combateram, entre 1963 e 1974, a ditadura de Salazar e Caetano (Pereira, 2013). Quinhentos anos depois da chegada a Lifau, a língua que o colonizador impôs no comércio, na guerra e na religião, servia ao colonizado de “bala maubere” no combate a nova colonização.

Lifau, berço da nacionalidade leste timorense
Creators: name: Ruas, Joana
Publisher: name: Povos e Culturas

description: Lifau foi a cidade onde as religiões, as culturas e as línguas se cruzaram e entrechocaram caoticamente. Foi um estranho abraço entre uma entidade oriental diversificada e outra, ocidental, arrogante dos seus valores e das suas armas. Foi um abraço de desejo e de medo, o áspero combate de conviver e o desespero de ter de se alienar para sobreviver. Na Europa, com a ruína da verdade absoluta, a exigência moral de cada homem foi posta à prova nos tumultos do mundo, no choque das paixões e no desconhecido que cada um traz em si mesmo. A moral que haviam escolhido para dar uma forma ao informe da vida, enredava-se não raro nas intrigas dos poderosos e na tremenda ânsia de lucros fáceis. Como tinha surgido na Europa, a noção de nação surgiu em Timor à medida que o critério religioso foi sendo substituído por um critério social. Uma política espiritual aliada à perseverança com que Portugal defendia os povos à sua guarda de agressores externos, supriu as bases de uma fé sem teologia dos neófitos. As gerações que se lhes seguiram puderam usufruir do benefício da sua firmeza e admirar estes homens dos tempos passados cuja força, determinação e coragem moldaram as fronteiras étnicas e religiosas de uma parte do território e o perfil de uma nova nação. Os povos de Timor-Leste tiveram que viver, sem que disso tivessem consciência, a trajetória da modernidade entendida como a tradição da rutura e a aceitação de viver um tempo inédito.

Os plurilinguismos de Timor-Leste

Publisher: name: Povos e Culturas
Year: 2015

description: Ao abordarmos a problemática das Línguas e Cultura na Textura da Nação Timorense, pareceu-nos pertinente estabelecer um percurso do contacto linguístico entre timorenses e outros povos, relacionando esse contacto com a construção das suas identidades plurilingues. Fundamentámos esta nossa opção no facto de as línguas não expressarem apenas essas identidades, mas também de as construírem, sendo, enquanto símbolos identitários, portadoras de conteúdo cultural (Dorian,1999). Situando-nos no contexto de Timor-Leste, onde o multilinguismo contribuiu para as lutas entre reinos, tendo sido aproveitado pelos portugueses, durante o período colonial, para dividir o povo timorense, o que conduziu ao fracasso das lutas pela independência. Já numa época mais recente, o povo timorense suplantou as suas divergências, face à necessidade de “unificar o combate” contra o invasor indonésio (Mattoso, 2012), adquirindo, assim, o tétum uma função de coesão social, de unidade nacional e identitária, entre outras. E que funções desempenham as restantes línguas endógenas e exógenas? E de que modo contribuem as línguas para a construção dessas identidades múltiplas? São estes, sumariamente, os propósitos que conduzirão a nossa reflexão neste texto.

We explore the sum uncertainty relations for arbitrary $N$ mutually noncommutative observables based on ($α,β,γ$) WWYD skew information. A series of uncertainty inequalities are derived. We show by detailed example that our results cover and improve the previous ones based on the original Wigner-Yanase (WY) skew information. Finally, we establish new sum uncertainty relations in terms of the ($α,β,γ$) MWWYD skew information for arbitrary $N$ quantum channels.

description: We present Exo-Transmit, a software package to calculate exoplanet transmission spectra for planets of varied composition. The code is designed to generate spectra of planets with a wide range of atmospheric composition, temperature, surface gravity, and size, and is therefore applicable to exoplanets ranging in mass and size from hot Jupiters down to rocky super-Earths. Spectra can be generated with or without clouds or hazes with options to (1) include an optically thick cloud deck at a user-specified atmospheric pressure or (2) to augment the nominal Rayleigh scattering by a user-specified factor. The Exo-Transmit code is written in C and is extremely easy to use. Typically the user will only need to edit parameters in a single user input file in order to run the code for a planet of their choosing. Exo-Transmit is available publicly on Github with open-source licensing at https://github.com/elizakempton/Exo_Transmit .

description: „Certainty-Based Marking“ (CBM) ist eine Methode zur Bewertung von geschlossenen Aufgabenformaten wie Single- oder Multiple-Choice. Die Lernenden geben bei jeder Aufgabe zusätzlich an, wie sicher sie sich mit ihrer Antwort sind. Diese Arbeit untersucht in einer experimentellen Online-Studie, ob CBM im Rahmen der Quiz-App „MedizinWissen2go“ sowie allgemein für Lernapps im Quiz-Format einen Mehrwert bietet. Neben einer allgemeinen Evaluation des Ansatzes liegt das Hauptaugenmerk auf der Betrachtung eines potenziell positiven Einflusses auf realistische Wissenseinschätzungen. Dies bezieht sich auf Selbsteinschätzungen von Lernenden sowie auf die Wissensdiagnostik. Die Studie konnte einen Mehrwert von CBM für diese beiden Bereiche nicht nachweisen. Eine kritische Auseinandersetzung mit den Ergebnissen und der Methodik der Arbeit bildet die Grundlage zur Diskussion der Frage, inwiefern Quiz-Apps und speziell „MedizinWissen2go“ dennoch von CBM profitieren können.

description: Anomalous diffusion is a common phenomenon observed in underground solute transport, soil water infiltration and sediment movement, etc. Time and space fractional derivative advection-dispersion equation (FADE) has been widely employed as the governing equation to characterize above mentioned anomalous diffusion related processes. However, a main problem in application of time and space FADE model to describe the real-world mass transport processes, is its low computation efficiency for long-time range and large irregular domain cases. This study offers a new algorithm in which the Kansa method is used for vector space fractional derivative term discretization and then analytical approach for resulted time fractional ordinary system. The influence of node distribution mode and node numbers on accuracy and convergence rate are analysed through the numerical examples in one and two dimensional cases. To test the application potentials of present methods, we offer the numerical results of two dimensional time and space FADE models in continuous and discrete cases. It shows that the solute plumes in heterogeneous and anisotropic media, can be well simulated by using present method compared with the previous time-consumed particle Monte-Carlo methods.

description: Despite its small size, the asteroid 4 Vesta has been completely differentiated to core and mantle. Its composition is similar to howardite--eucrite--diogenite (HED) meteorites of which the detailed petrology is known. Therefore, Vesta is a good target for understanding the differentiation of terrestrial planets. A new differentiation model for crust formation has been developed by taking magma ocean fluid dynamics, chemical equilibrium, the presence of $^{26}$Al, and cooling into consideration with a special focus on crystal separation. The role of crystal size, thickness of the conductive lid, and fO$_{2}$ are evaluated as parameters. The results show that large crystals of at least 1 cm settled and formed a kilometer-thick cumulate layer of orthopyroxene with Mg$\#$ of 0.70-0.90 in ~20 thousand years, which almost agrees with the Mg$\#$ of diogenites. Smaller grain sizes formed thinner layers.

description: Spatial heteroskedasticity refers to stochastically changing variances and covariances in space. Such features have been observed in, for example, air pollution and vegetation data. We study how volatility modulated moving averages can model this by developing theory, simulation and statistical inference methods. For illustration, we also apply our procedure to sea surface temperature anomaly data from the International Research Institute for Climate and Society.

description: The rise of topological insulators in recent years has broken new ground both in the conceptual cognition of condensed matter physics and the promising revolution of the electronic devices. It also stimulates the explorations of more topological states of matter. Topological crystalline insulator is a new topological phase, which combines the electronic topology and crystal symmetry together. In this article, we review the recent progress in the studies of SnTe-class topological crystalline insulator materials. Starting from the topological identifications in the aspects of the bulk topology, surface states calculations and experimental observations, we present the electronic properties of topological crystalline insulators under various perturbations, including native defect, chemical doping, strain, and thickness-dependent confinement effects, and then discuss their unique quantum transport properties, such as valley-selective filtering and helicity-resolved functionalities for Dirac fermions. The rich properties and high tunability make SnTe-class materials promising candidates for novel quantum devices.

Portugal e os portugueses em geral, têm sido, desde a primeira hora, convictos e activos – senão mesmo apaixonados – promotores e defensores da causa timorense, tanto no seu caminho para a libertação e independência, que tem como marco principal o referendo de 30 de Agosto de 1999, como desde a histórica criação da República Democrática de Timor-Leste, a 20 de Maio de 2002. As múltiplas iniciativas e demonstrações de solidariedade do povo português no contexto do processo que conduziu à independência de Timor-Leste disso são inequívoca expressão. Apoiamos hoje em dia, com idêntico afinco, um país independente e soberano, num estreito relacionamento enraizado em afecto e amizade mútuos, mas simultaneamente consubstanciado em estreitos e dinâmicos laços de cooperação em várias áreas com a vocação de contribuir, da melhor forma possível, para apoiar Timor-Leste no seu caminho para o pleno desenvolvimento.

description: Uncertainty relation is a fundamental issue in quantum mechanics and quantum information theory. By using modified generalized variance (MGV), and modified generalized Wigner-Yanase-Dyson skew information (MGWYD), we identify the total and quantum uncertainty of quantum channels. The elegant properties of the total uncertainty of quantum channels are explored in detail. In addition, we present a trade-off relation between the total uncertainty of quantum channels and the entanglement fidelity and establish the relationships between the total uncertainty and entropy exchange/coherent information. Detailed examples are given to the explicit formulas of the total uncertainty and the quantum uncertainty of quantum channels. Moreover, utilizing a realizable experimental measurement scheme by using the Mach-Zehnder interferometer proposed in Nirala et al. (Phys Rev A 99:022111, 2019), we discuss how to measure the total/quantum uncertainty of quantum channels for pure states.

description: Near Earth Objects (NEOs) are small Solar System bodies whose orbits bring them close to the Earth's orbit. We are carrying out a Warm Spitzer Cycle 11 Exploration Science program entitled NEOSurvey --- a fast and efficient flux-limited survey of 597 known NEOs in which we derive diameter and albedo for each target. The vast majority of our targets are too faint to be observed by NEOWISE, though a small sample has been or will be observed by both observatories, which allows for a cross-check of our mutual results. Our primary goal is to create a large and uniform catalog of NEO properties. We present here the first results from this new program: fluxes and derived diameters and albedos for 80 NEOs, together with a description of the overall program and approach, including several updates to our thermal model. The largest source of error in our diameter and albedo solutions, which derive from our single band thermal emission measurements, is uncertainty in eta, the beaming parameter used in our thermal modeling; for albedos, improvements in Solar System absolute magnitudes would also help significantly. All data and derived diameters and albedos from this entire program are being posted on a publicly accessible webpage at nearearthobjects.nau.edu .

description: Azobenzene macrocycles are widely investigated as potential drug delivery systems and as part of molecular machines due to their photo-responsive properties. Herein, we detect the formation of a series of new azobenzene macrocycles that feature up to eight switchable repeating units. High-resolution mass spectrometry and ion mobility (IM) mass spectrometry experiments and 1H and diffusion-ordered spectroscopy (DOSY) NMR are used to detect the presence of the macrocycles that contain 10 to 40 aromatic rings in the gas phase and solution, respectively. The responsiveness of the Z-to-E photo-switching of the smallest of the macrocycles, exhibiting 2 azobenzene units and in total 10 aromatic rings, separated with column chromatography, is studied with irradiation experiments, using both UV-Vis light and thermal excitation and relaxation, and monitoring the sample with UV-Vis absorption and 1H NMR spectroscopy. DFT calculations are used to understand the conformation of this isolated species in solution.

description: Spatiotemporal activity prediction, aiming to predict user activities at a specific location and time, is crucial for applications like urban planning and mobile advertising. Existing solutions based on tensor decomposition or graph embedding suffer from the following two major limitations: 1) ignoring the fine-grained similarities of user preferences; 2) user's modeling is entangled. In this work, we propose a hypergraph neural network model called DisenHCN to bridge the above gaps. In particular, we first unify the fine-grained user similarity and the complex matching between user preferences and spatiotemporal activity into a heterogeneous hypergraph. We then disentangle the user representations into different aspects (location-aware, time-aware, and activity-aware) and aggregate corresponding aspect's features on the constructed hypergraph, capturing high-order relations from different aspects and disentangles the impact of each aspect for final prediction. Extensive experiments show that our DisenHCN outperforms the state-of-the-art methods by 14.23% to 18.10% on four real-world datasets. Further studies also convincingly verify the rationality of each component in our DisenHCN.

description: An ideal solid-state supermirror (SM) neutron polarizer assumes total reflection of neutrons from the SM coating for one spin-component and total absorption for the other, thus providing a perfectly polarized neutron beam at the exit. However, in practice, the substrate's neutron-nucleai optical potential does not match perfectly that for spin-down neutrons in the SM. For a positive step in the optical potential (as in a Fe/SiN(x) SM on Si substrate), this mismatch results in spin-independent total reflection for neutrons with small momentum transfer Q, limiting the useful neutron bandwidth in the low-Q region. To overcome this limitation, we propose to replace Si single-crystal substrates by media with higher optical potential than that for spin-down neutrons in the SM ferromagnetic layers. We found single-crystal sapphire and single-crystal quartz as good candidates for solid-state Fe/SiN(x) SM polarizers. To verify this idea, we coated a thick plate of single-crystal sapphire with a m=2.4 Fe/SiN(x) SM. At the T3 instrument at the ILL, we measured the spin-up and spin-down reflectivity curves with 7.5 A neutrons incident from the substrate to the interface between the substrate and the SM coating. The results of this experimental test were in excellent agreement with our expectations: the bandwidth of high polarizing power extended significantly into the low-Q region. This finding, together with the possibility to apply a strong magnetizing field, opens a new road to produce high-efficient solid-state SM polarizers with an extended neutron wavelength bandwidth and near-to-perfect polarizing power.

description: As a result of mass-digitisation efforts, cultural heritage and research institutions have had to adapt their practices to account for shifts in what cultural stewardship and the study of cultural memory entails. Representations of cultural assets in the form of 3D models within disciplines such as architecture, art, archaeology, and 3D reconstruction are particularly heterogeneous in formats and structure, ergo standardized access and visualisation tools face new challenges. Furthermore, cultural memory preservation requires the active participation of diverse audiences who can easily access, search and enrich datasets through annotations and critical interpretations. This poster presents the development of a suite of tools as part of the NFDI4Culture project focusing on such enrichment. The toolchain facilitates the annotation of 3D data within a knowledge graph (Wikibase) and a sophisticated rendering environment (Kompakkt), so that 3D objects’ geometry, attendant metadata and annotations are accessible and searchable as part of the semantic web. The extended abstract for this poster is published separately as part of the DHd 2022 Proceedings and is available here: https://zenodo.org/record/6328155

description: The observational cosmology with distant Type Ia supernovae (SNe) as standard candles claims that the Universe is in accelerated expansion, caused by a large fraction of dark energy. In this paper we investigate the SN Ia environment, studying the impact of the nature of their host galaxies on the Hubble diagram fitting. The supernovae (192 SNe) used in the analysis were extracted from Joint-Light-curves-Analysis (JLA) compilation of high-redshift and nearby supernovae which is the best one to date. The analysis is based on the empirical fact that SN Ia luminosities depend on their light curve shapes and colors. We confirm that the stretch parameter of Type Ia supernovae is correlated with the host galaxy type. The supernovae with lower stretch are hosted mainly in elliptical and lenticular galaxies. No significant correlation between SN Ia colour and host morphology was found. We also examine how the luminosities of SNe Ia change depending on host galaxy morphology after stretch and colour corrections. Our results show that in old stellar populations and low dust environments, the supernovae are slightly fainter. SNe Ia in elliptical and lenticular galaxies have a higher $α$ (slope in luminosity-stretch) and $β$ (slope in luminosity-colour) parameter than in spirals. However, the observed shift is at the 1-$σ$ uncertainty level and, therefore, can not be considered as significant. We confirm that the supernova properties depend on their environment and that the incorporation of a host galaxy term into the Hubble diagram fit is expected to be crucial for future cosmological analyses.

description: This is the second deliverable of Waorkpackage 5. It aims to provide tips and tools for the organization of international events for SMEs, both online and in presence. At the time of the proposal writing, almost all the events were designed for running in presence, and the experience of the clusters (partners of the project) was mainly related to the organization of this kind of networking and business events. The clusters are used to face Volatility, Uncertainty, Complexity, and Ambiguity (VUCA): four main challenges in the cluster mission to support European SMEs in increasing their competitiveness and resilience. These challenges were exacerbated by Covid 19 pandemic and made the whole consortium to re-think and re-build the organization of events and networking opportunities for SMEs. The management of the typical cluster activities thus changed during the project duration, and the partners had the possibility to explore new ways of building relationships with SMEs and with the selected countries outside Europe, carefully evaluating the changing travelling conditions due to the sanitary emergency and also studying new and innovative tools for creating business meeting. During the pandemic, clusters constantly monitored markets in search for new challenges and trends to develop, test, and evaluate targeted services for their members. Lastly, they established strategic partnerships with other ecosystems as gateways to go-to-market opportunities and support for companies. By acting this way, clusters became an important tool for SMEs to stay connected with the markets. This was done by organizing webinars to provide market insights, enhance companies´ visibility and matchmaking opportunities. Moreover, by strengthening the exchange of information between organizations, clusters acted as a marketplace with collaboration offers and hints on funding opportunities for their members. All these changes also affected the FoodPackLab 2.0 activities and the planned events. In this deliverable we are thus presenting the know-how of the consortium partners in the organization of in-presence events (i.e. before pandemic); the new digital tools that were adopted for networking during pandemic; new approaches for b2b meetings to face travelling restrictions; tips and tricks for hybrid meetings organized in the last months of the project. In the final conclusion paragraph a new way of managing this kind of projects is highlighted.

description: The mixed spin-1/2 and spin-5/2 Ising model is investigated on the Bethe lattice in the presence of a magnetic field $h$ via the recursion relations method. A ground-state phase diagram is constructed which may be needful to explore important regions of the temperature phase diagrams of a model. The order-parameters, the corresponding response functions and internal energy are thoroughly investigated in order to typify the nature of the phase transition and to get the corresponding temperatures. So, in the absence of the magnetic field, the temperature phase diagrams are displayed in the case of an equal crystal-field on the $(k_{\textrm{B}}T/|J|, \,D/|J|)$ plane when $q=3,4$, $5$ and $6$. The model only exhibits the second-order phase transition for appropriate values of physical parameters of a model.

description: Particle contamination of extreme ultraviolet (EUV) photomasks is one of the numerous challenges in nanoscale semiconductor fabrication, since it can lead to systematic device failures when disturbed patterns are projected repeatedly onto wafers during EUV exposure. Understanding adhesion of particle contamination is key in devising a strategy for cleaning of photomasks. In this work, particle contamination is treated as a particle-plane problem in which surface roughness and the interacting materials have major influences. For this purpose, we perform vacuum atomic force microscopy (AFM) contact measurements to quantify the van der Waals (vdW) forces between tip and sample. We introduce this as a vacuum AFM-based methodology that combines numerical Hamaker theory and Blind Tip Reconstruction (BTR). We have determined the Hamaker constants of $15x10^{-20} J$ and $13x10^{-20} J$ for the material systems of a silicon (Si) tip with both aluminum oxide ($Al_{2}O_{3}$) and native silicon dioxide ($SiO_{2}$) on Si substrates, respectively. Our methodology allows an alternative, quick and low-cost approach to characterize the Hamaker constant within the right order of magnitude for any material combination.
