description: Populations of heterogeneous phase oscillators with frustrated random interactions exhibit a quasi-glassy state in which the distribution of local fields is volcano-shaped. In a recent work [Phys. Rev. Lett. 120, 264102 (2018)] the volcano transition was replicated in a solvable model using a low-rank, random coupling matrix $\mathbf M$. We extend here that model including tunable nonreciprocal interactions, i.e. ${\mathbf M}^T\ne \mathbf M$. More specifically, we formulate two different solvable models. In both of them the volcano transition persists if matrix elements $M_{jk}$ and $M_{kj}$ are enough correlated. Our numerical simulations fully confirm the analytical results. To put our work in a wider context, we also investigate numerically the volcano transition in the analogous model with a full-rank random coupling matrix.

description: De nombreuses études documentent les risques de la pratique du vélo durant le printemps, l’été et l’automne. Or, les risques du vélo d’hiver, et les potentielles particularités associées à cette saison, n’ont, à ce jour, été que très peu explorés. De plus, aucune recherche ne porte sur les disparités entre les risques perçus par les cyclistes et les risques observés. Cette recherche vise à documenter les risques liés à la pratique du vélo d’hiver à Montréal et à identifier les écarts entre les risques perçus et réels. Les données primaires sont issues d’observations non participatives des trajets de dix cyclistes entre les mois de février et de mars 2022 à Montréal, et de dix entretiens semi-dirigés. L’analyse des données a permis d’identifier les risques des déplacements à vélo l’hiver et d’infirmer certaines hypothèses d’une pratique plus dangereuse. En effet, les cyclistes ne considèrent pas que les déplacements durant l’hiver sont plus dangereux que durant les autres saisons. Le principal risque du vélo d’hiver est, comme pour les autres saisons, associé à la cohabitation avec les véhicules motorisés. Ce risque est accentué par la réduction de l’espace de circulation sur les voies routières et les bandes cyclables lorsqu’il y a une accumulation de neige en bordure de la chaussée. Aussi, les chutes sont très rares et les situations problématiques associées à l’entretien du réseau cyclable ne représentent pas un enjeu pour ces personnes. Ainsi, grâce à une planification supplémentaire, telle que l’établissement au préalable d’un trajet jugé sécuritaire et la priorisation du réseau cyclable protégé et entretenu, la pratique du vélo d’hiver n’engendre pas de risques supplémentaires pour les cyclistes initié.e.s comparativement aux autres saisons.

description: From DFT based calculations establishing energy-volume equations of state and electron localization mapping, the electronic structure and crystal chemistry changes from Sn2TiO4 to Sn2TiO6 by oxidation are rationalized; the key effect being the destabilization of divalent tin SnII towards tetravalent state SnIV leading to rutile Sn2TiO6 as experimentally observed. The subsequent electronic structure change is highlighted in the relative change of the electronic band gap which increases from ~1eV up to 2.2 eV and the 1.5 times increase of the bulk modulus assigned to the change from covalently SnII based compound to the more ionic SnIV one. Such trends are also confronted with the relevant properties of black SnIIO characterized by very small band gap.

description: In this paper we develop a microscopic analysis of the light scattering on a periodic two-level atomic array coupled to an optical nanofiber. We extend the scattering matrix approach for two-level system interaction with nanofiber fundamental waveguiding mode HE_{11}, that allows us modeling the scattering spectra. We support these results considering the dispersion of the polaritonic states formed by the superposition of the fundamental mode of light HE_{11} and the atomic chain states. To illustrate our approach we start with considering a simple model of light scattering over atomic array in the free space. We discuss the Bragg diffraction at the atomic array and show that the scattering spectrum is defined by the non-symmetric coupling of two-level system with nanofiber and vacuum modes. The proposed method allows considering two-level systems interaction with full account for dipole-dipole interaction both via near fields and long-range interaction owing to nanofiber mode coupling.

description: In the present work, extended Argon ion bombardment was used to modify anatase TiO2 nanotube (NTs) layers. In situ X-ray photoelectron spectroscopy revealed a high content of sub-oxide formed (Ti3+, Ti2+ states) in the nanotube layers. These samples were tested for their ability to show open-circuit photocatalytic hydrogen evolution. We found for UV (cw laser 325nm) illumination as well as for AM1.5 conditions, a strongly enhanced H2 evolution activity in absence of the usual noble metal-nanoparticle decoration. We conclude therefore that these sub-oxide states can play an important role in the activation of TiO2 nanotubes - namely as a H2 evolution co-catalyst.

description: While social media plays a vital role in communication nowadays, misinformation and trolls can easily take over the conversation and steer public opinion on these platforms. We saw the effect of misinformation during the COVID-19 pandemic when public health officials faced significant push-back while trying to motivate the public to vaccinate. To tackle the current and any future threats in emergencies and motivate the public towards a common goal, it is essential to understand how public motivation shifts and which topics resonate among the general population. In this study, we proposed an interactive visualization tool to inspect and analyze the topics that resonated among Twitter-sphere during the COVID-19 pandemic and understand the key factors that shifted public stance for vaccination. This tool can easily be generalized for any scenario for visual analysis and to increase the transparency of social media data for researchers and the general population alike.
Spin Partners of the $B^{(*)}\bar{B}^{(*)}$ resonances with a different approach than the Breit-Wigner parameterization

Publisher: name: arXiv
Year: 2023
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In general, resonances are obtained by the Breit-Wigner parameterization. However, it is not entirely appropriate to use this parameterization with near-threshold resonances such as the $Z_b(10610)$ and the $Z_b(10650)$, as Breit-Wigner does not contain the threshold effect. To eliminate this defect, a recently proposed alternative distribution, the Sill, is used to predict possible heavy quark spin symmetry partners of the $Z_b(10610)$ and the $Z_b(10650)$. With the Sill values of the $Z_b(10650)$ and the $Z_b(10610)$ states, assuming these exotics generate molecular states consisting of contact and a pion exchange potential, heavy quark spin symmetry partners are examined with $S$ and $D$-wave contributions. In the light of the Sill type resonance approach, all the partners are found as bound states.

description: We deal with the higher-order fractional Laplacians by two methods: the integral method and the system method. The former depends on the integral equation equivalent to the differential equation. The latter works directly on the differential equations. We first derive nonexistence of positive solutions, often known as the Liouville type theorem, for the integral and differential equations. Then through an delicate iteration, we show symmetry for positive solutions.

description: We present an angle-resolved photoemission spectroscopy study of the single-layer T*-type structured cuprate SmLa$_{1-x}$Sr$_x$CuO$_4$ with unique five-fold pyramidal oxygen coordination. Upon varying oxygen content, T*-SmLa$_{1-x}$Sr$_x$CuO$_4$ evolved from a Mott-insulating to a metallic state where the Luttinger sum rule breaks down under the assumption of a large hole-like Fermi surface. This is in contrast with the known doping evolution of the structural isomer La$_{2-x}$Sr$_x$CuO$_4$ with six-fold octahedral coordination. In addition, quantitatively characterized Fermi surface suggests that the empirical $T_\mathrm{c}$ rule for octahedral oxygen-coordination systems does not apply to T*-SmLa$_{1-x}$Sr$_x$CuO$_4$. The present results highlight unique properties of the T*-type cuprates possibly rooted in its oxygen coordination, and necessitate thorough investigation with careful evaluation of disorder effects.

To determine the coherence times of superpositions of all orders in the 4-dimensional Hilbert space, we use a phase-cycling technique and find that, when electrical effects were allowed to decay, these times scale as expected for a field-like decoherence mechanism such as the interaction with surrounding $^{29}$Si nuclear spins.

Publisher: name: University of Alberta Library
Year: 2022

In this paper, a relationship between a load applied on the inner ring and strains measured on the outer ring of a bearing is studied. A linear relationship is confirmed under different loading conditions. Finite element analysis of a cylindrical rolling element bearing with 11 rollers is conducted in ANSYS to collect the strain data on the outer ring of the bearing. Static load and varying loads are applied to the inner ring of the bearing. Strains collected on the outer ring show a linear relationship to the radial load applied on the inner ring. The linear coefficient k is identical under static and sinusoid varying loads for each roller. With the linear relationship, a simple method is proposed to calculate the contact force between a roller and the outer ring very accurately with an error of less than 1.5%, according to the simulation results.

We show that $L_n$ is almost the same as $Ω_{n}$ except for some boundary points. We also present an upper bound for the number of vertices of $Ω_{n}$.

Order-2 Asymptotic Optimality of the Fully Distributed Sequential Hypothesis Test

Subjects: subject: Applications (stat.AP)

description: This work analyzes the asymptotic performances of fully distributed sequential hypothesis testing procedures as the type-I and type-II error rates approach zero, in the context of a sensor network without a fusion center. In particular, the sensor network is defined by an undirected graph, where each sensor can observe samples over time, access the information from the adjacent sensors, and perform the sequential test based on its own decision statistic. Different from most literature, the sampling process and the information exchange process in our framework take place simultaneously (or, at least in comparable time-scales), thus cannot be decoupled from one another. Two message-passing schemes are considered, based on which the distributed sequential probability ratio test (DSPRT) is carried out respectively. The first scheme features the dissemination of the raw samples. Although the sample propagation based DSPRT is shown to yield the asymptotically optimal performance at each sensor, it incurs excessive inter-sensor communication overhead due to the exchange of raw samples with index information. The second scheme adopts the consensus algorithm, where the local decision statistic is exchanged between sensors instead of the raw samples, thus significantly lowering the communication requirement compared to the first scheme. In particular, the decision statistic for DSPRT at each sensor is updated by the weighted average of the decision statistics in the neighbourhood at every message-passing step. We show that, under certain regularity conditions, the consensus algorithm based DSPRT also yields the order-2 asymptotically optimal performance at all sensors.

A quasi-monoenergetic photon beam produced via the laser Compton scattering technique was irradiated on the active-target time-projection chamber filled with helium gas, and trajectories of charged decay particles emitted from $^4$He were measured. Our data suggest that the $^4$He($γ, n$)$^3$He and $^4$He($γ, p$)$^3$H cross sections peak around 26 MeV. This result contradicts the previous experimental data reported by Shima et al. but is consistent with other experimental results.

description: Smart home energy management systems help the distribution grid operate more efficiently and reliably, and enable effective penetration of distributed renewable energy sources. These systems rely on robust forecasting, optimization, and control/scheduling algorithms that can handle the uncertain nature of demand and renewable generation. This paper proposes an advanced ML algorithm, called Recurrent Trend Predictive Neural Network based Forecast Embedded Scheduling (rTPNN-FES), to provide efficient residential demand control. rTPNN-FES is a novel neural network architecture that simultaneously forecasts renewable energy generation and schedules household appliances. By its embedded structure, rTPNN-FES eliminates the utilization of separate algorithms for forecasting and scheduling and generates a schedule that is robust against forecasting errors. This paper also evaluates the performance of the proposed algorithm for an IoT-enabled smart home. The evaluation results reveal that rTPNN-FES provides near-optimal scheduling $37.5$ times faster than the optimization while outperforming state-of-the-art forecasting techniques.

description: Our most important Zn resources occur within clastic-dominated (CD-type) deposits, which are located in a small number of Proterozoic and Phanerozoic sedimentary basins. The most common model for CD-type mineralisation involves sedimentary exhalative (SEDEX) processes, i.e. the venting of metal bearing fluids into a restricted, anoxic H2S-bearing (euxinic) water column. In the Carpentaria Zn Province (Australia), multiple world class deposits are hosted in Proterozoic (1.6 Ga) stratigraphy, where models of the ancient sulfur cycle have also been developed. Focusing on the most recent discovery – the Teena deposit – we report bulk rock and isotopic data (δ34Spyrite values) that provide information on the sulfur cycle during the diagenetic and hydrothermal evolution of the Teena sub-basin. In contrast to the SEDEX model, intervals containing abundant pyrite with highly positive δ34S values (>25 ‰) correspond with euxinic conditions that developed due to high organic loading (i.e. productivity) and not basin restriction. This basin wide feature, which can also be mistaken as a hydrothermal pyrite halo, is genetically unrelated to the subsequent hydrothermal mineralisation that formed beneath the palaeo-seafloor. The formation of CD-type deposits in the Proterozoic does not, therefore, require euxinic conditions.

description: This research examines the experiences and motivation of high school learners of French who participated in a short student exchange program. For most students, positive family attitudes and experiences in early high school supported motivation, despite a challenging transition when the subject became elective. Anticipation of their exchange allowed students to imagine themselves becoming successful speakers of French, increasing motivation. In France, immersive engagement with host families established connections and enhanced self-confidence. The study suggests that the exchange program was a transformational experience, linking academic ambitions and a desire to travel, and boosting motivation before, during and after the program.

description: Im Zuge der archäologischen Erschließung Ägyptens und des Vorderen Orients im 19. Jahrhundert kamen zahlreiche Menschendarstellungen aus den Kulturen des Altertums zum Vorschein, die auch jenseits der Altertums‐ und Kunstwissenschaften große Faszination auszuüben vermochten. Dabei wurden insbesondere altägyptische Statuen und Reliefs weniger als ästhetische Repräsentationen, sondern als mimetisch‐typologische Darstellungen wahrgenommen, die nicht nur bestimmte Individuen, sondern ganze Völker mit ihren charakteristischen physischen Merkmalen abbilden. Vor diesem Hintergrund avancierten Abbildungen dieser Bildwerke zu wichtigen visuellen Referenzen anthropologischer Publikationen und sollten die Konstanz vermeintlicher Rassenmerkmale und damit die Gültigkeit wissenschaftlicher Klassifikationen belegen. Anhand vornehmlich deutschsprachiger Publikationen aus dem 19. und frühen 20. Jahrhundert rekonstruiert der Beitrag die epistemologischen Voraussetzungen und bildästhetischen Prämissen der anthropologischen Lektüre altägyptischer Menschendarstellungen und geht der Frage nach, warum sich dieses Verfahren weitgehend auf Objekte aus den Kulturen des Alten Orients konzentrierte. Im Fokus steht hier die klassizistische Kunst‐ und Körperauffassung, die auf der einen Seite einer anthropologischen Lektüre von Objekten aus der klassischen Antike im Wege stand, auf der anderen aber dazu beitrug, den ägyptischen jenen mimetischen und typologischen Charakter zuzuweisen, der sie als visuelle Referenzen auch für die physische Anthropologie attraktiv machte.

description: Recent experiments with droplets impacting a macro-textured superhydrophobic surfaces revealed new regimes of bouncing with a remarkable reduction of the contact time. We present here a comprehensive numerical study that reveals the physics behind these new bouncing regimes and quantify the role played by various external and internal forces that effect the dynamics of a drop impacting a complex surface. For the first time, three-dimensional simulations involving macro-textured surfaces are performed. Aside from demonstrating that simulations reproduce experiments in a quantitative manner, the study is focused on analyzing the flow situations beyond current experiments. We show that the experimentally observed reduction of contact time extends to higher Weber numbers, and analyze the role played by the texture density. Moreover, we report a non-linear behavior of the contact time with the increase of the Weber number for application relevant imperfectly coated textures, and also study the impact on tilted surfaces in a wide range of Weber numbers. Finally, we present novel energy analysis techniques that elaborate and quantify the interplay between the kinetic and surface energy, and the role played by the dissipation for various Weber numbers.
Inhibition of NF-kappaB signalling by a family of type III secretion system effector proteins during Salmonella infection
Creators: name: Jennings, Elliott James
Publisher: name: Imperial College London
Year: 2018

description: During Salmonella infection, bacterial proteins called ‘effectors’ are translocated into host cells by two type III secretion system apparatuses encoded by Salmonella-pathogenicity island 1 and 2. These effectors manipulate host cell processes to facilitate the formation of an intracellular replicative niche, to prevent bacterial clearance, and ultimately promote bacterial transmission to another susceptible host. A subset of SPI-2 T3SS effector proteins manipulate innate immune signalling pathways thereby preventing formation of an appropriate immune response. In this thesis, I identify three related effector proteins - GtgA, GogA, and PipA, as sufficient to inhibit NF-kappaB signalling when expressed ectopically. Furthermore, I demonstrate that GtgA, GogA, and PipA are zinc metalloproteases that inhibit NF-kappaB signalling by cleaving the NF-kappaB transcription factor subunits p65, cRel, and RelB, but not NF-kappaB1 (p105/p50) or NF-kappaB2 (p100/p52). Accordingly, in Salmonella-infected cells, p65 was cleaved dependent on gtgA, gogA, and pipA leading to inhibition of NF-kappaB signalling. To investigate the molecular basis for substrate recognition, mutational analysis of residues in close proximity to the p65 cleavage site (G40/R41) was done and showed that the P1’ residue (R41 in p65) is a critical determinant of substrate specificity. In NF-kappaB1 and NF-kappaB2, a proline residue is present at the corresponding site and this residue prevents cleavage by GtgA, GogA, and PipA. I also present the crystal structure of GtgA alone and in complex with the N-terminal domain of p65. The crystal structure demonstrates the importance of the P1’ residue in substrate specificity and supports a model of DNA mimicry as the mechanism of substrate recognition. This thesis therefore provides detailed insight into the functions and mechanism of substrate recognition, for a family of previously uncharacterised Salmonella virulence proteins.

The DINACON-V controller was used with the CCD to achieve high performance and low noise. The CCD system photometric characteristics are presented. A spatial autocorrelation analysis of flat-field images was performed to reveal the dependence of substrate voltage on the lateral charge spreading. The investigation of the dispersion index for the optimal choice of exposure time is discussed. Studies of the patterns of fringes were carried out in comparison with previous detectors. The amplitude of fringes with CCD261-84 was significantly lower, compared to previous-generation detectors. The results of using a new camera for imaging and spectral observations at the Russian 6 m telescope with the SCORPIO-2 multimode focal reducer are considered. The developed CCD camera system makes it possible to significantly increase the sensitivity in the 800-1000 spectral range.

Interplay between vitamin D and metabolic factors in colorectal cancer development: a molecular epidemiology approach
Creators: name: Al-Dabhani, Kawthar
Publisher: name: Imperial College London
Year: 2019

description: Observational studies have reported that higher levels of serum vitamin D are associated with lower risk of colorectal cancer (CRC) and metabolic syndrome (MetS). Given the fact that MetS and its components are also associated with CRC, the potential causal pathways between vitamin D, MetS and its components, and CRC are not well understood. At the same time, observational studies have inherit limitations and can only assess association rather than causation. Alternatively, the Mendelian randomisation (MR) approach uses genetic variants as proxies for an environmental exposure and can be used to provide more robust evidence for potential causality. In this thesis I used a variety of methods to study the interlinked effects of vitamin D, MetS, and CRC. Mediation analysis was used to assess whether the association between vitamin D and CRC was mediated by MetS in the EPIC cohort. I further assessed the potential causal association between vitamin D and CRC using both individual and summary-level data in EPIC, UK Biobank, the GECCO consortium and data from the SUNLIGHT consortium. Moreover, I assessed the direction of potential causal relationship between vitamin D and MetS components using summary-level data from genetic consortia. Among the 2,300 participants in EPIC, MetS mediated ~18% of the association between vitamin D and CRC. No significant causal association between vitamin D and CRC was found for either the individual-level data in EPIC (OR: 1.03, 95%CI: 0.99 – 1.06), or for the larger studies using summary-level data in the UK Biobank (OR: 0.86, 95%CI: 0.68 – 1.08) or GECCO (OR: 0.92, 95%CI: 0.76 – 1.10). I also assessed the potential causal association between vitamin D and MetS components and found that a 1 standard deviation decrease in the natural log transformed 25-hydroxyvitamin D (25(OH)D) was associated with a 4% increase in HbA1c levels. The results also showed that high BMI and low levels of HDL cholesterol reduced the levels of 25(OH)D, and that high levels of HbA1c and SBP increased 25(OH)D levels. To conclude, no evidence for a causal association was found between vitamin D and CRC. Further research needs to be conducted to understand the inconsistency of results between observational and MR analyses of vitamin D and CRC. Moreover, evidence of causality was found between vitamin D and MetS components; however, present methods cannot reliably infer the directionality of these associations.

description: In a radio interferometer, the determination of geometrical antenna positions relies on accurate calibration of the dry and wet delay of the atmosphere above each antenna. For the Atacama Large Millimeter/Submillimeter Array (ALMA), which has baseline lengths up to 16 kilometers, the geography of the site forces the height above mean sea level of the more distant antenna pads to be significantly lower than the central array. Thus, both the ground level meteorological values and the total water column can be quite different between antennas in the extended configurations. During 2015, a network of six additional weather stations was installed to monitor pressure, temperature, relative humidity and wind velocity, in order to test whether inclusion of these parameters could improve the repeatability of antenna position determinations in these configurations. We present an analysis of the data obtained during the ALMA Long Baseline Campaign of Oct. through Nov. 2015. The repeatability of antenna position measurements typically degrades as a function of antenna distance. Also, the scatter is more than three times worse in the vertical direction than in the local tangent plane, suggesting that a systematic effect is limiting the measurements. So far we have explored correcting the delay model for deviations from hydrostatic equilibrium in the measured air pressure and separating the partial pressure of water from the total pressure using water vapor radiometer (WVR) data. Correcting for these combined effects still does not provide a good match to the residual position errors in the vertical direction. One hypothesis is that the current model of water vapor may be too simple to fully remove the day-to-day variations in the wet delay. We describe possible avenues of improvement, including measuring and applying more accurate values of the sky coupling efficiency of the WVRs.

Dynamics of the histone modification H3K27me3 on plant development
Creators: name: Mermaz, Benoit
Publisher: name: Imperial College London
Year: 2019

description: In plants, the H3K27me3 modification, established by the subunit of the Polycomb Repressive Complex 2 showing a methyltransferase activity, is present at more than 4400 genes, which are mostly transcription factors involved in major plants developmental processes. The first aim of this thesis is to test whether nascent RNA could be present at PRC2 targeted genes and whether these nascents RNA could act as anchor point for cis-elements to recruit PRC2 to a specific locus. The presence of nascent RNA at Polycomb repressed genes was demonstrated in Arabidopsis before adapting a new innovative chromatin tool, called Chromatin Isolation by RNA Precipitation (ChIRP), to isolate and identify proteins interacting with nascent RNA. The fully optimized method revealed nineteen candidate proteins to interact specifically with the nascent RNA at the FLC locus (Chapter 3) but the link to PRC2 recruitment is yet to be shown and should be investigated in the future. The second aim of this thesis is to determine the effects of the H3K27me3 erasers on plant development. The flowering time, the fertility and the embryo to seedling transition were studied in different Arabidopsis plants lacking the different demethylases, REF6, ELF6 and JMJ13. It showed antagonist phenotype suggesting very distinct roles. Flowering time studies identified four potential targets of JMJ13, FLC, SNZ, AGL24 and SOC1 that require further validation (Chapter 4) while the effect of ELF6 and REF6 on the flowering time have been described several years ago. Fertility studies showed JMJ13 promotes stamen elongation while ELF6 suppresses stamen and promotes pistil elongations. Seed analysis revealed that the seed size and weight are negatively affected by the demethylases and that REF6 and ELF6 share redundancy (Chapter 5). Germination rate analysis showed JMJ13 suppresses germination while ELF6 and REF6 promote it and the embryo-to-seedling transition study revealed ELF6 is partially required to generate true leaves (Chapter 6). The characterisation of the effects of the demethylases on Arabidopsis development has started recently and should be investigated to better understand the regulation of plant life cycle by the histone demethylases.

description: The discovery of superconducting materials has led to their use in technological marvels such as magnetic-field sensors in MRI machines, powerful research magnets, short transmission cables, and high-speed trains. Despite such applications, the uses of superconductors are not widespread because they function much below room-temperature, hence the costly cooling. Since the discovery of Cu- and Fe-based high-temperature superconductors (HTS), much intense effort has tried to explain and understand the superconducting phenomenon. While no exact explanations are given, several trends are reported in relation to the materials basis in magnetism and spin excitations. In fact, most HTS have antiferromagnetic undoped 'parent' materials that undergo a superconducting transition upon small chemical substitutions in them. As it is currently unclear which 'dopants' can favor superconductivity, this manuscript investigates crystal structure changes upon chemical substitutions, to find clues in lattice parameters for the superconducting occurrence. We review the chemical substitution effects on the crystal lattice of iron-arsenide-based crystals (2008 to present). We note that (a) HTS compounds have nearly tetragonal structures with a-lattice parameter close to 4 A, and (b) superconductivity can depend strongly on the c-lattice parameter changes with chemical substitution. For example, a decrease in c-lattice parameter is required to induce 'in-plane' superconductivity. The review of lattice parameter trends in iron-arsenides presented here should guide synthesis of new materials and provoke theoretical input, giving clues for HTS.

Community Engagement Index

description: We present an integrated approach to the quantitative assessment of science communication activities of research projects. In particular, we introduce the community engagement index and the communication effectiveness quadrants plot. The former is a metric integrating all communication activities into one single index and representing the engagement of a community with the project. The latter is a dynamic graph to monitor and improve the performance of communication products. Our methodology can be applied to research initiatives of different kinds and geographical scope. Indeed it has been tested on a diverse set of EU-funded projects on disparate thematic areas.

description: Der russische Überfall auf die Ukraine im Februar 2022 hat neben den verheerenden Folgen vor allem für die ukrainische Bevölkerung auch zu globalen Verwerfungen geführt. Die Rivalität zwischen den Großmächten USA und China, die sich im letzten Jahrzehnt sukzessive aufgebaut hat, scheint sich durch den Ukraine-Konflikt zu einer Konfliktkonstellation zwischen den USA, der NATO, der EU und ihren Verbündeten auf der einen und Russland, China und ihren Verbündeten auf der anderen Seite zu erweitern und zu verschärfen. Südkorea gehört zu einer Reihe von Ländern, die sich in dieser Situation noch enger an den Westen binden wollen. Vor diesem Hintergrund beschäftigt sich der folgende Text damit, wie Südkorea – mit dem neuen konservativen Präsidenten Yoon Suk-yeol etwas mehr als ein Jahr im Amt – auf den Ukraine-Konflikt und die daraus resultierenden weltpolitischen Herausforderungen reagiert und was die Gründe dafür sind.
