description: EuroFIR AISBL – new centre of excellence for data on food launchedThe new centre of excellence for data on the composition of food in Europe, EuroFIR AISBL, was launched in Brussels as continuation of the EC-funded EuroFIR Network of Excellence, which ran from 2005 until June this year.

The Managing Director of EuroFIR AISBL, Paul Finglas from the Institute of Food Research in Norwich, UK, described the importance of this new organisation: “Accurate information on what is in our food is more important than ever and many, including regulators, health professionals, scientists as well as the food industry, rely on food composition data to do their jobs. The EuroFIR Network brought together key experts from across Europe to ensure that we have good quality data on our food, and EuroFIR AISBL is continuing and developing this work”.

EuroFIR AISBL is funded by membership from academic institutions, regulators, food industry and individual food and nutrition professionals. Members receive a number of benefits including use of the eSearch facility allowing simultaneous online searching of the most up-to-date and standardised food composition datasets, access to specialised data sets such as the eBASIS database on plant bioactive compounds, and tailored consultancy and training.

At a EuroFIR AISBL stakeholder event held in Brussels earlier this year, external partners of the organisation came together to listen to presentations from those involved in the AISBL, the European Commission (EC), and from organisations with links to the project including the European Committee for Standardisation (CEN), the European Prospective Investigation into Cancer (EPIC), and the European Food Safety Authority (EFSA).

description: We explore the shape and internal structure of diblock copolymer (di-BCP) nanoparticles (NPs) by using the Ginzburg-Landau free-energy expansion. The self-assembly of di-BCP lamellae confined in emulsion droplets can form either ellipsoidal or onion-like NPs. The corresponding inner structure is a lamellar phase that is either perpendicular to the long axis of the ellipsoids (L$_\perp$) or forms a multi-layer concentric shell (C$_\parallel$), respectively. We focus on the effects of the interaction parameter between the A/B monomers $τ$, and the polymer/solvent $χ$, as well as the NP size on the nanoparticle shape and internal morphology. The aspect ratio ($l_{\rm AR}$) defined as the length ratio between the long and short axes is used to characterize the overall NP shape. Our results show that for the solvent that is neutral towards the two blocks, as $τ$ increases, the $l_{\rm AR}$ of the NP first increases and then decreases, indicating that the NP becomes more elongated and then changes to a spherical NP. Likewise, decreasing $χ$ or increasing the NP size can result in a more elongated NP. However, when the solvent has a preference towards the A or B blocks, the NP shape changes from striped ellipsoid to onion-like sphere by increasing the A/B preference parameter strength. The critical condition of the transition from an L$_\perp$ to C$_\parallel$ phase has been identified. Our results are in good agreement with previous experiments, and some of our predictions could be tested in future experiments.

description: The origin of the pseudogap behavior, found in many high-$T_c$ superconductors, remains one of the greatest puzzles in condensed matter physics. One possible mechanism is fermionic incoherence, which near a quantum critical point allows pair formation but suppresses superconductivity. Employing quantum Monte Carlo simulations of a model of itinerant fermions coupled to ferromagnetic spin fluctuations, represented by a quantum rotor, we report numerical evidence of pseudogap behavior, emerging from pairing fluctuations in a quantum-critical non-Fermi liquid. Specifically, we observe enhanced pairing fluctuations and a partial gap opening in the fermionic spectrum. However, the system remains non-superconducting until reaching a much lower temperature. In the pseudogap regime the system displays a "gap-filling" rather than "gap-closing" behavior, consistent with experimental observations. Our results provide the first unambiguous lattice model realization of a pseudogap state in a strongly correlated system, driven by superconducting fluctuations.

description: The UniProtKB/Swiss-Prot Plant Protein Annotation Program has been actively collaborating with other resources. We recently started to collaborate with Araport, the Arabidopsis portal, and we provide Araport with all the gene model corrections that we introduced on the bases of our trans-species family annotation. We are also completing the knowledgebase by importing missing information from EnsemblPlants.

Manual expert curation of UniProtKB/Swiss-Prot is complemented by expert-driven automatic annotation of UniProtKB/TrEMBL entries to build comprehensive, high quality sets of proteins covering complete proteome of several plant species. The complete proteomes of Arabidopsis and rice are synchronized with the ones proposed by Araport and Gramene respectively.

Data from high-throughput proteomics experiments constitute a rich potential source of annotations for UniProtKB. Certified experimental peptides that uniquely match the product of a single gene are used to generate annotations describing post-translational modifications and protein processing events, and to confirm protein existence. Around 2’600 Arabidopsis entries are now containing annotations extracted from 11 reviewed articles describing large scale proteomics experiments.

description: It is known that the loss of phase coherence of Cooper pairs in two-dimensional (2D) superconductivity corresponds to the unbinding of vortex-antivortex pairs with the quasi-long-range order (quasi-LRO) in the order-parameter phase field, described by the Berezinskii-Kosterlizt-Thouless (BKT) transition of a 2D XY model. Here we show that the second-order Josephson coupling can induce an exotic superconducting phase in a bilayer system. By using tensor-network methods, the partition function of the 2D classical model is expressed as a product of 1D quantum transfer operator, whose eigen-equation can be solved by an algorithm of matrix product states rigorously. From the singularity shown by the entanglement entropy of the 1D quantum analogue, various phase transitions can be accurately determined. Below the BKT phase transition, an inter-layer Ising long-range order is established at $T_{Ising}$, and the phase coherence of both intra-layers and inter-layers is locked together. For two identical layers, the Ising transition coincides with the BKT transition at a multi-critical point. For two inequivalent layers, however, there emerges an intermediate quasi-LRO phase ($T_{Ising}

description: An effective 3D descriptor should be invariant to different geometric transformations, such as scale and rotation, robust to occlusions and clutter, and capable of generalising to different application domains. We present a simple yet effective method to learn general and distinctive 3D local descriptors that can be used to register point clouds that are captured in different domains. Point cloud patches are extracted, canonicalised with respect to their local reference frame, and encoded into scale and rotation-invariant compact descriptors by a deep neural network that is invariant to permutations of the input points. This design is what enables our descriptors to generalise across domains. We evaluate and compare our descriptors with alternative handcrafted and deep learning-based descriptors on several indoor and outdoor datasets that are reconstructed by using both RGBD sensors and laser scanners. Our descriptors outperform most recent descriptors by a large margin in terms of generalisation, and also become the state of the art in benchmarks where training and testing are performed in the same domain.

One main ingredient in order to establish these relations is Blaschke's shaking procedure, by which the problem can be reduced from arbitrary convex bodies to anti-blocking bodies. As a consequence of our results, we obtain an upper bound on the lattice point enumerator in terms of the successive minima, which is equivalent to Minkowski's upper bound on the volume in terms of the successive minima.

BACKGROUND: HIV self-testing (HIVST) is effective in improving the uptake of HIV testing among key populations. Complementary data on the economic evaluation of HIVST is critical for planning and scaling up HIVST. This study aimed to evaluate the cost of a community-based organisation (CBO)-led HIVST model implemented in China. METHODS: An economic evaluation was conducted by comparing a CBO-led HIVST model with a CBO-led facility-based HIV rapid diagnostics testing (HIV-RDT) model. The full economic cost, including fixed and variable cost, from a health provider perspective using a micro costing approach was estimated. We determined the incremental cost-effectiveness ratios of these two HIV testing models over a 2-yeartime horizon (i.e. duration of the programs), and reported costs using US dollars (2021). RESULTS: From January 2017 to December 2018, a total of 4633 men were tested in the HIVST model, and 1780 men were tested in the HIV-RDT model. The total number of new diagnoses was 155 for HIVST and 126 for the HIV-RDT model; the HIV test positivity was 3.3% (95% confidence interval (CI): 2.8-3.9) for the HIVST model and 7.1% (95% CI: 5.9-8.4) for the HIV-RDT model. The mean cost per person tested was USD10.38 for HIVST and USD41.45 for HIV-RDT. The mean cost per diagnosed person was USD310.12 for HIVST compared with USD585.58 for HIV-RDT. CONCLUSION: Compared to facility-based HIV-RDT, a CBO-led HIVST program is cheaper and more effective among MSM living in China.

Facilitating Sexual and Gender Minority (SGM) Indigenous Youth to Grow into Resilience  through Cultural Intersections
Creators: Anna Wilson
Publisher: name: University of Alberta Library
Year: 2016

This paper explores how transgender youth can grow into resilience through

the mixture of cultural intersections (concept of Métissage) on the history of Two Spirit (TS)

people, Navajo culture, and the Alaskan Two Spirit Braided Resiliency Framework, which can

help transgender youth to develop their own conception of gender beautifully.

First, Western research on the risk factors and protective factors of SGM youth will be

examined. Second, the concept of Métissage will be explained in the context of the Canadian

Indian Residential School Crisis (IRS). Third, the history of Two Spirit (TS) people and Navajo

culture will be explored. Fourth, the two spirit of concept of circularity will be braided into

Maenette Benham AhNee-Benham’s educational leadership model. This circulates as an

Indigenous ecological macro-system circulating resiliency through youths’ meso-systems into

their micro-systems (Masten, 2015, p. 220). Fifth, the Alaskan Two Spirit Braided Resiliency

Framework will braid the strands of this research together enabling transgender youth to develop

their own conception of gender beautifully. Implications for future practice in public institutions

will be provided in an effort to meet these challenges to promote the best practices possible for

helping two spirit and Indigenous transgender youth grow into resilience.

description: For minimum-error channel discrimination tasks that involve only unitary channels, we show that sequential strategies may outperform the parallel ones. Additionally, we show that general strategies that involve indefinite causal order are also advantageous for this task. However, for the task of discriminating a uniformly distributed set of unitary channels that forms a group, we show that parallel strategies are, indeed, optimal, even when compared to general strategies. We also show that strategies based on the quantum switch cannot outperform sequential strategies in the discrimination of unitary channels. Finally, we derive an absolute upper bound for the maximal probability of successfully discriminating any set of unitary channels with any number of copies for the most general strategies that are suitable for channel discrimination. Our bound is tight since it is saturated by sets of unitary channels forming a group k-design.

Year: 2025

description: This thesis explores the role of Augmented Reality (AR) in improving vocabulary retention among English language learners. With the advancement of educational technologies, AR has emerged as a powerful tool that can create immersive and interactive learning environments. The paper discusses how AR applications, such as 3D visualizations and real-world overlays, can engage learners more effectively than traditional methods, leading to better memory retention and contextual understanding of vocabulary items. The study also reviews existing literature, presents practical examples of AR use in English language teaching, and highlights the challenges of integrating AR into classroom settings, particularly in developing contexts.

description: As HPC systems continue to grow to exascale, the amount of data that needs to be saved or transmitted is exploding. To this end, many previous works have studied using error-bounded lossy compressors to reduce the data size and improve the I/O performance. However, little work has been done for effectively offloading lossy compression onto FPGA-based SmartNICs to reduce the compression overhead. In this paper, we propose a hardware-algorithm codesign for an efficient and adaptive lossy compressor for scientific data on FPGAs (called CEAZ), which is the first lossy compressor that can achieve high compression ratios and throughputs simultaneously. Specifically, we propose an efficient Huffman coding approach that can adaptively update Huffman codewords online based on codewords generated offline, from a variety of representative scientific datasets. Moreover, we derive a theoretical analysis to support a precise control of compression ratio under an error-bounded compression mode, enabling accurate offline Huffman codewords generation. This also helps us create a fixed-ratio compression mode for consistent throughput. In addition, we develop an efficient compression pipeline by adopting cuSZ's dual-quantization algorithm to our hardware use cases. Finally, we evaluate CEAZ on five real-world datasets with both a single FPGA board and 128 nodes (to accelerate parallel I/O). Experiments show that CEAZ outperforms the second-best FPGA-based lossy compressor by 2.3X of throughput and 3.0X of ratio. It also improves MPI_File_write and MPI_Gather throughputs by up to 28.9X and 37.8X, respectively.

description: Legged robots have excellent terrestrial mobility for traversing diverse environments and thus have the potential to be deployed in a wide variety of scenarios. However, they are susceptible to falling and leg malfunction during locomotion. Although the use of a large number of legs can overcome these problems, it makes the body long and leads to many legs being constrained to contact with the ground to support the long body, which impedes maneuverability. To improve the locomotion maneuverability of such robots, the present study focuses on dynamic instability, which induces rapid and large movement changes, and uses a 12-legged robot with a flexible body axis. Our previous work found that the straight walk of the robot becomes unstable through Hopf bifurcation when the body axis flexibility is changed, which induces body undulations. Furthermore, we developed a simple controller based on the Hopf bifurcation and showed that the instability facilitates the turning of the robot. In this study, we newly found that the straight walk becomes unstable through pitchfork bifurcation when the body-axis flexibility is changed in a way different from that in our previous work. In addition, the pitchfork bifurcation induces a transition into a curved walk, whose curvature can be controlled by the body-axis flexibility. We developed a simple controller based on the pitchfork-bifurcation characteristics and demonstrated that the robot can perform a turning maneuver superior to that with the previous controller. This study provides a novel design principle for maneuverable locomotion of many-legged robots using intrinsic dynamic properties.
Can Super Resolution be used to improve Human Pose Estimation in Low Resolution Scenarios?

description: The results obtained from state of the art human pose estimation (HPE) models degrade rapidly when evaluating people of a low resolution, but can super resolution (SR) be used to help mitigate this effect? By using various SR approaches we enhanced two low resolution datasets and evaluated the change in performance of both an object and keypoint detector as well as end-to-end HPE results. We remark the following observations. First we find that for people who were originally depicted at a low resolution (segmentation area in pixels), their keypoint detection performance would improve once SR was applied. Second, the keypoint detection performance gained is dependent on that persons pixel count in the original image prior to any application of SR; keypoint detection performance was improved when SR was applied to people with a small initial segmentation area, but degrades as this becomes larger. To address this we introduced a novel Mask-RCNN approach, utilising a segmentation area threshold to decide when to use SR during the keypoint detection step. This approach achieved the best results on our low resolution datasets for each HPE performance metrics.

description: Let $ k $ be a field, $ G $ a totally ordered abelian group and $ \mathbb K = k((G)) $ the maximal field of generalised power series, endowed with the canonical valuation $ v $. We study the group $ v \mathrm{-Aut} K $ of valuation preserving automorphisms of a subfield $ k(G)\subseteq K\subseteq \mathbb K $, where $ k(G) $ is the fraction field of the group ring $ k[G] $. Under the assumption that $ K $ satisfies two lifting properties we are able to generalise and refine Hofberger's decomposition of $ v \mathrm{-Aut}\mathbb K $ and prove a structure theorem decomposing $ v\mathrm{-Aut} K $ into a 4-factor semi-direct product of notable subgroups. We then identify a large class of Hahn fields satisfying the two aforementioned lifting properties. Next we focus on the group of strongly additive automorphisms of $ K $. We give an explicit description of the group of strongly additive internal automorphisms in terms of the groups of homomorphisms $ \mathrm{Hom}(G,k^\times) $ of $ G $ into $ k^\times $ and $ \mathrm{Hom}(G,1+I_K) $ of $ G $ into the group of 1-units of the valuation ring of $ K $. Finally, we specialise our results to some relevant special cases. In particular, we extend the work of Schilling on the field of Laurent series and that of Deschamps on the field of Puiseux series.

Year: 2014

description: This thesis describes investigations into the optical and device design of organic light-emitting diodes (OLEDs) with the aim of exploring the factors controlling the spatial emission pattern of OLEDs and developing novel OLEDs with directional emission by applying wavelength-scale photonic microstructure. The development of directional OLEDs was broken down into two steps: the development of efficient narrow linewidth OLEDs and the integration of wavelength-scale photonic microstructures into narrow linewidth OLEDs. The narrow linewidth OLEDs were developed using europium (Eu) complexes. The electrical optimisation of solution-processed Eu-based OLEDs using commercially available materials was investigated. The optimised Eu-based OLEDs gave an external quantum efficiency of 4.3% at a display brightness of 100 cd/m². To our knowledge, this is the highest efficiency reported for solution-processed Eu-based OLED devices, and the efficiency roll-off has been reduced compared with other reported references. Photonic microstructures were applied to develop directional OLEDs using the efficient Eu-based OLEDs. Two contrasting strategies were used. One was to embed photonic microstructures into Eu-based OLEDs, the other was to couple photonic microstructures externally onto the devices. The microstructured devices developed by the former strategy boosted the emitted power in desired angles in both s- and p-polarisations and doubled the fraction of emission in an angle range of 4⁰. The devices developed by the external coupling strategy achieved even higher directionality and the out-coupled emission was a confined beam with easy control of beam steering. Around 90% of the emitted power was confined in an angular range of 20⁰ in the detection plane. The optical properties can be optimised independently without compromising the electrical properties of devices, which gives major advantages in terms of effectiveness and versatility. Optical models were also developed to investigate the out-coupling mechanism of various trapped modes and develop OLEDs with stronger directionality.

description: The transfer of chirality across length-scales is an intriguing and universal natural phenomenon. However, connecting the properties of individual building blocks to the emergent features of their resulting large-scale structure remains a challenge. In this work, we investigate the origins of mesophase chirality in cellulose nanocrystal suspensions, whose self-assembly into chiral photonic films has attracted significant interest. By correlating the ensemble behaviour in suspensions and films with a quantitative morphological analysis of the individual nanoparticles, we reveal an inverse relationship between the cholesteric pitch and the abundance of laterally-bound composite particles. These bundles thus act as colloidal chiral dopants, analogous to those used in molecular liquid crystals, providing the missing link in the hierarchical transfer of chirality from the molecular to the colloidal scale.

description: The simple symplectic triple systems over the real numbers are classified up to isomorphism, and linear models of all of them are provided. Besides the split cases, one for each complex simple Lie algebra, there are two kinds of non-split real simple symplectic triple systems with classical enveloping algebra, called unitarian and quaternionic types, and five non-split real simple symplectic triple systems with exceptional enveloping algebra.

description: The measurement of parameters that describe kinetic processes is important in the study of molecular interactions. It enables a deeper understanding of the physical mechanisms underlying how different biological entities interact with each other, such as viruses with cells, vaccines with antibodies, or new drugs with specific diseases. In this work, we study theoretically the use of quantum sensing techniques for measuring the kinetic parameters of molecular interactions. The sensor we consider is a plasmonic resonance sensor -- a label-free photonic sensor that is one of the most widely used in research and industry. The first type of interaction we study is the antigen BSA interacting with antibody IgG1, which provides a large sensor response. The second type is the enzyme carbonic anhydrase interacting with the tumor growth inhibitor benzenesulfonamide, which produces a small sensor response. For both types of interaction we consider the use of two-mode Fock states, squeezed vacuum states and squeezed displaced states. We find that these quantum states offer an enhancement in the measurement precision of kinetic parameters when compared to that obtained with classical light. The results may help in the design of more precise quantum-based sensors for studying kinetics in the life sciences.

description: A set grading on the split simple Lie algebra of type $D_{13}$, that cannot be realized as a group-grading, is constructed by splitting the set of positive roots into a disjoint union of pairs of orthogonal roots, following a pattern provided by the lines of the projective plane over $GF(3)$. This answers in the negative Question 1.11 in Elduque-Kochetov monograph (2013). Similar non-group gradings are obtained for types $D_n$ with $n$ congruent to 1 modulo 12, by substituting the lines in the projective plane by blocks of suitable Steiner systems.

description: Trapped-ion quantum simulators, in analog and digital modes, are considered a primary candidate to achieve quantum advantage in quantum simulation and quantum computation. The underlying controlled ion-laser interactions induce all-to-all two-spin interactions via the collective modes of motion through Cirac-Zoller or Molmer-Sorensen schemes, leading to effective two-spin Hamiltonians, as well as two-qubit entangling gates. In this work, the Molmer-Sorensen scheme is extended to induce three-spin interactions via tailored first- and second-order spin-motion couplings. The scheme enables engineering single-, two-, and three-spin interactions, and can be tuned via an enhanced protocol to simulate purely three-spin dynamics. Analytical results for the effective evolution are presented, along with detailed numerical simulations of the full dynamics to support the accuracy and feasibility of the proposed scheme for near-term applications. With a focus on quantum simulation, the advantage of a direct analog implementation of three-spin dynamics is demonstrated via the example of matter-gauge interactions in the U(1) lattice gauge theory within the quantum link model. The mapping of degrees of freedom and strategies for scaling the three-spin scheme to larger systems, are detailed, along with a discussion of the expected outcome of the simulation of the quantum link model given realistic fidelities in the upcoming experiments. The applications of the three-spin scheme go beyond the lattice gauge theory example studied here and include studies of static and dynamical phase diagrams of strongly interacting condensed-matter systems modeled by two- and three-spin Hamiltonians.

title: Affinity-Maintenance Strategies and Relationship Satisfaction

Year: 1996

description: This study examined the influence of affinity maintenance strategies (i.e., positivity, openness, assurances and sharing tasks) on relationship satisfaction. An individual's perception of his or her partner's affinity-maintenance behaviors was investigated. Gender differences and sex-role attitudes were also examined. Using Stafford and Canary's (1991) Affinity-Maintenance Strategy Measure and Hendrick's (1988) Relationship Assessment Scale, positive correlations were found between the frequency of positivity and relationship satisfaction for males and females. The perception of partner's use of sharing tasks was positively correlated with relationship satisfaction. Gender differences were not found in how frequently males or females utilized affinity-maintenance strategies within their relationship. Using Hem's Sex Role Inventory (1974), subjects rating high in expressiveness utilized affinity-maintenance strategies more than subjects rating low in expressiveness. Implications for future research and couple's therapy are discussed.
Statistical Uncertainties of the $N_\text{DW} = 1$ QCD Axion Mass Window from Topological Defects

description: We review results from QCD axion string and domain wall simulations and propagate the associated uncertainties, including QCD uncertainties, into the calculation of the axion relic density. We compare two different sets of studies and, using cosmological constraints, perform statistical inference on the axion mass window in the post-inflationary Peccei-Quinn symmetry breaking scenario. For dark matter axions in recent simulations inferring a moderately infrared-dominated spectrum, this leads to a median dark matter axion mass of 0.50 meV, while the 95% credible interval at highest posterior density is between 0.48 and 0.52 meV. For alternative simulations including in addition string-domain wall decays (but with different overall inference on the spectrum), these numbers are 0.22 meV and [0.16, 0.27] meV. Relaxing the condition that axions are all of the dark matter, the axion mass window is completed by an upper bound of around 80 meV, which comes from dark radiation constraints. This confirms that the axion mass can be constrained rather precisely regarding statistical uncertainties and further calls for a more detailed analysis of the various sources of systematic uncertainties plaguing the simulations.

description: In this work, it is investigated the behavior of the efficiency at maximum power of a quantum dot molecule, acting as a device for photovoltaic conversion. A theoretical approach using a master equation, considering the effect of the energy offsets, and the width of the quantum barrier, identifies realistic physical conditions that enhance the photovoltaic response of the photocell. The results show the potentiality of increasing the gain in 30\% of maximum power delivered per molecule if compared with a single quantum dot. Also, the system exhibits gain when compared to the Chambadal-Novikov efficiency at maximum power, without exceeding Carnot's efficiency, as expected from the second law of thermodynamics.

description: Cette campagne de mesure s'inscrit dans le cadre du cours d'océanographie expérimentale du programme de M1 Physique et Sciences de l'Ingénieur (M1 PSI) et du cours d'océanographie physique du programme de L3 Physique de l'Environnement (L3 PE) de l'Université du Sud Toulon-Var. Elle a pour objectif de permettre aux étudiants de prendre connaissance des principes fondamentaux de la planification et de la réalisation d'une campagne à la mer et de se familiariser avec les instruments les plus couramment utilisés (CTD, ADCP, thermosalinographe, flotteurs dérivants...). L'objet scientifique principal de la campagne 2009 était la caractérisation de la circulation entre la côte et le Courant Nord (ou courant Liguro-Provençal) dans la zone toulonaise, et plus particulièrement au voisinage du site ANTARES. Il s'agissait d'illustrer et décrire les structures thermo-halines (CTD et thermosalinographe) associées au courant, de calculer les vitesses géostrophiques inhérentes ou les vitesses lagrangiennes (lâchers de flotteurs de surface) pour des comparaisons avec les vitesses mesurées par l'ADCP. En complément de ce plan général, deux opérations liées à des projets de recherche en cours ont planifiées lors de la campagne (récupération/déploiement glider de la DT INSU et test de portée radar HF) afin de présenter de façon concrète deux autres techniques d'observation aux étudiants et ainsi d'élargir la portée pédagogique de la campagne.Les projets de rattachement sont les missions pédagogiques, M1 Physique et Sciences de l'Ingénieur (M1 PSI) et L3 Physique de l'Environnement (L3 PE) de l'Université du Sud Toulon-Var, Radiale glider ANTARES, projet ECCOP.
