description: Cache timing attack is a type of side channel attack where the leaking timing information due to the cache behaviour of a crypto system is used by an attacker to break the system. Advanced Encryption Standard (AES) was considered a secure encryption standard until 2005 when Daniel Bernstein claimed that the software implementation of AES is vulnerable to cache timing attack. Bernstein demonstrated a remote cache timing attack on a software implementation of AES. The original AES implementation can methodically be altered to prevent the cache timing attack by hiding the natural cache-timing pattern during the encryption while preserving its semantics. The alternations while preventing the attack should not make the implementation very slow. In this paper, we report outcomes of our experiments on designing and implementing a number of possible countermeasures.
Development of diode-pumped Alexandrite laser systems for atmospheric remote sensing
Creators: name: Coney, Alexander Thomas
Publisher: name: Imperial College London
Year: 2019

description: The aim of this work is to produce a diode-pumped alexandrite proof-of-concept Master Oscillator Power Amplifier (MOPA) design for satellite-based lidar. Atmospheric remote sensing enables accurate weather predictions, climate change observations and detailed atmospheric topography. Current space-based lidar systems use diode-pumped Nd:YAG systems and are limited to the harmonics of 1064 nm, 532 nm and 355 nm. Alexandrite sources offer a range of operation from 720 nm - 820 nm. This allows lidar techniques such as resonance scattering to be used, providing more topographical data and profiling over a greater altitude range. A diode-pumped alexandrite Q-switched oscillator is developed with a record-breaking pulse energy of 3.80 mJ. This involves multiple cavity designs and iterations. A diode-pumped seed oscillator is produced with an M-squared of 1.06 for amplifier characterisation. A novel amplifier design, the diamond geometry, is introduced. This produces the world's first diode-pumped alexandrite amplifier with a gain of 1.73. The multi-pass amplifier is experimentally optimised with seed wavelength and crystal temperature. The results are used to verify modelling based on a Frantz-Nodvik analysis. The proposed diode-pumped alexandrite MOPA design consists of a single-longitudinal mode ring oscillator producing 5 mJ which seeds a two-stage amplifier, producing 50 mJ. The pre-amplifier and power amplifier are based on the diamond geometry. The proposed design is optimised for seed wavelength, crystal temperature, pump pulse duration and number of passes. The design is scalable, offering optimum operation at 750 nm but with a further option for 770 nm (potassium lidar). A diode-pumped Nd:YAG MOPA is produced, enabling a comparison between alexandrite and current satellite-based lidar sources. The Q-switched zig-zag oscillator produces a pulse energy of 98 mJ. This is amplified to 265 mJ within a zig-zag amplifier. The system has been developed within Leonardo. This company developed the ALADIN laser launched in 2018.

description: Recent progress in our studies of propagators and three-point functions in Landau gauge for QCD and QCD-like theories is presented. Special emphasis is put on the properties of the three-gluon vertex and the quark-gluon vertex. The effect of unquenching is investigated. Furthermore, an exploratory study for a large number of light flavours is described, from where clear evidence for the qualitative behaviour of propagators in the so-called conformal window can be extracted.

description: Pathogenic mutations in lamin A/C (LMNA) lead to nuclear structural abnormalities, mesenchymal tissue damage, and laminopathies, which have numerous tissue-specific and progeria phenotypes, including mandibuloacral dysplasia type A. However, how LMNA mutations lead to accelerated mesenchymal-derived cell senescence and disease development remains unclear. Here, we established a replicative senescence model in vitro using induced pluripotent stem cell-derived mesenchymal stem cells (iMSCs) from patients with homozygous LMNA p.R527C mutation (LMNA R527C iMSCs). R527C iMSCs exhibited marked cell senescence and stemness potential attenuation, accompanied by immunophenotypic changes when expanded to passage 13 in vitro. Transcriptome analysis revealed that DNA replication, nuclear structure, and chromatin-related gene sets were the most significant changes in R527C iMSCs during replicative senescence, and pathways such as cell cycle, DNA replication, cell adhesion, and inflammation might play important roles in senescence.

description: We describe quasi-Hopf twist deformations of flat closed string compactifications with non-geometric R-flux using a suitable cochain twist, and construct nonassociative deformations of fields and differential calculus. We report on our new findings in using this formalism to construct perturbative nonassociative field theories on these backgrounds. We describe the modifications to the usual classification of Feynman diagrams into planar and non-planar graphs. The example of phi(4) theory is studied in detail and the one-loop contributions to the two-point function are calculated.

description: We have demonstrated the laser frequency offset locking via the Rb tripod-type double dark resonances electromagnetically induced transparency (EIT) system. The influence of coupling fields power and detuning on the tripod-type EIT profile is detailed studied. In a wide coupling fields detuning range, the narrower EIT dip has an ultranarrow linewidth of 590 KHz, which is about one order narrower than the natural linewidth of Rb. Without the additional frequency stabilization of the coupling lasers, we achieve the relative frequency fluctuation of 60 KHz in a long time of ~2000s, which is narrower than the short-time linewidth of each individual laser.

OOP

description: The once-only principle (OOP) is a principle which states that public administrations should collect information from citizens and businesses only once, and then share and reuse this information. This is seen as a way to increase government efficiency and reduce the administrative burden of citizens and businesses in their interactions with public administrations. In the context of the European Single Market, data should not only be shared internally within a country but also between Member States. In spite of political expectations and technical advances, the cross-border implementation of the OOP in the EU has been limited to a few services so far. The Once-Only Principle Project (TOOP) is an EU-funded large-scale project which aims to explore and demonstrate the OOP on a cross-border pan-European scale, focusing on reducing the administrative burden of businesses. This will be achieved by developing a federated architecture for interconnecting information systems in different countries, and testing this in multiple pilots. TOOP has the potential to provide lessons learned which may assist future implementation and a wider usage of the OOP. This is expected to bring positive changes both for public administrations and public service users across Europe and beyond. This position paper describes the current state of affairs as regards the implementation of the OOP in Europe and explains the project’s approach towards OOP, summarizing the motivation and ambition behind the project.

description: We observed RX J0520.5-6932 in the X-rays and studied the optical light curve of its counterpart to verify it as a Be/X-ray binary. We performed an XMM-Newton anticipated target of opportunity observation in January 2013 during an X-ray outburst of the source in order to search for pulsations and derive its spectral properties. We monitored the source with Swift to follow the evolution of the outburst and to look for further outbursts to verify the regular pattern seen in the optical light curve with a period of ~24.4 d. The XMM-Newton EPIC light curves show coherent X-ray pulsations with a period of 8.035331(15) s (1 sigma). The X-ray spectrum can be modelled by an absorbed power law with photon index of ~0.8, an additional black-body component with temperature of ~0.25 keV and an Fe K line. Phase-resolved X-ray spectroscopy reveals that the spectrum varies with pulse phase. We confirm the identification of the optical counterpart within the error circle of XMM-Newton at an angular distance of ~0.8 arcsec, which is an O9Ve star with known Halpha emission. By analyzing the combined data from three OGLE phases we derived an optical period of 24.43 d.The X-ray pulsations and long-term variability, as well as the properties of the optical counterpart, confirm that RX J0520.5-6932 is a Be/X-ray binary pulsar in the Large Magellanic Cloud. Based on the X-ray monitoring of the source we conclude that the event in January 2013 was a moderately bright type-I X-ray outburst, with a peak luminosity of 1.79e36 erg/s.

We illustrate our method by demonstrating how to measure topological invariants in a two-dimensional quantum Hall-like model.

description: We analyze the phase structure of mass- and spin-imbalanced unitary Fermi gases in harmonic traps. To this end, we employ Density Functional Theory in the local density approximation. Depending on the values of the control parameters measuring mass and spin imbalance, we observe that three regions exist in the trap, namely: a superfluid region at the center, surrounded by a mixed region of resonantly interacting spin-up and spin-down fermions, and finally a fully polarized phase surrounding the previous two regions. We also find regimes in the phase diagram where the existence of a superfluid region at the center of the trap is not energetically favored. We point out the limitations of our approach at the present stage, and call for more detailed (ab initio) studies of the equation of state of uniform, mass-imbalanced unitary Fermi gases.

description: Processing data received as a stream is a task commonly performed by modern embedded devices, in a wide range of applications such as multimedia (encoding/decoding/ playing media), networking (switching and routing), digital security, scientific data processing, etc. Such processing normally tends to be calculation intensive and therefore requiring significant processing power. Therefore, hardware acceleration methods to increase the performance of such applications constitute an important area of study. In this paper, we present an evaluation of one such method to process streaming data, namely multi-processor pipeline architecture. The hardware is based on a Multiple-Processor System on Chip (MPSoC), using a data encryption algorithm as a case study. The algorithm is partitioned on a coarse grained level and mapped on to an MPSoC with five processor cores in a pipeline, using specifically configured Xtensa LX3 cores. The system is then selectively optimized by strengthening and pruning the resources of each processor core. The optimized system is evaluated and compared against an optimal single-processor System on Chip (SoC) for the same application. The multiple-processor pipeline system for data encryption algorithms used was observed to provide significant speed ups, up to 4.45 times that of the single-processor system, which is close to the ideal speed up from a five-stage pipeline.

description: Intrasaccular flow disruptors treat cerebral aneurysms by diverting the blood flow from the aneurysm sac. Residual flow into the sac after the intervention is a failure that could be due to the use of an undersized device, or to vascular anatomy and clinical condition of the patient. We report a machine learning model based on over 100 clinical and imaging features that predict the outcome of wide-neck bifurcation aneurysm treatment with an intravascular embolization device. We combine clinical features with a diverse set of common and novel imaging measurements within a random forest model. We also develop neural network segmentation algorithms in 2D and 3D to contour the sac in angiographic images and automatically calculate the imaging features. These deliver 90% overlap with manual contouring in 2D and 83% in 3D. Our predictive model classifies complete vs. partial occlusion outcomes with an accuracy of 75.31%, and weighted F1-score of 0.74.

description: As surrogate functions of $L_0$-norm, many nonconvex penalty functions have been proposed to enhance the sparse vector recovery. It is easy to extend these nonconvex penalty functions on singular values of a matrix to enhance low-rank matrix recovery. However, different from convex optimization, solving the nonconvex low-rank minimization problem is much more challenging than the nonconvex sparse minimization problem. We observe that all the existing nonconvex penalty functions are concave and monotonically increasing on $[0,\infty)$. Thus their gradients are decreasing functions. Based on this property, we propose an Iteratively Reweighted Nuclear Norm (IRNN) algorithm to solve the nonconvex nonsmooth low-rank minimization problem. IRNN iteratively solves a Weighted Singular Value Thresholding (WSVT) problem. By setting the weight vector as the gradient of the concave penalty function, the WSVT problem has a closed form solution. In theory, we prove that IRNN decreases the objective function value monotonically, and any limit point is a stationary point. Extensive experiments on both synthetic data and real images demonstrate that IRNN enhances the low-rank matrix recovery compared with state-of-the-art convex algorithms.

description: In this work we present theoretical calculations and analysis of the vibronic structure of the spin-triplet optical transition in diamond nitrogen-vacancy centres. The electronic structure of the defect is described using accurate first-principles methods based on hybrid functionals. We devise a computational methodology to determine the coupling between electrons and phonons during an optical transition in the dilute limit. As a result, our approach yields a smooth spectral function of electron-phonon coupling and includes both quasi-localized and bulk phonons on equal footings. The luminescence lineshape is determined via the generating function approach. We obtain a highly accurate description of the luminescence band, including all key parameters such as the Huang-Rhys factor, the Debye-Waller factor, and the frequency of the dominant phonon mode. More importantly, our work provides insight into the vibrational structure of nitrogen vacancy centres, in particular the role of local modes and vibrational resonances. In particular, we find that the pronounced mode at 65 meV is a vibrational resonance, and we quantify localization properties of this mode. These excellent results for the benchmark diamond nitrogen-vacancy centre provide confidence that the procedure can be applied to other defects, including alternative systems that are being considered for applications in quantum information processing.

description: Diese Arbeit untersucht die an technologische Konnektivität gelegten Hoffnungen in der Entstehungsgeschichte des Internets und vergleicht diese mit verschiedenen literarischen Science-Fiction Werken. Dazu wurden Aussagen von Pionieren der Computerwissenschaft kontextualisiert. Außerdem wurden diverse Science-Fiction Werke mit realen technologischen Praktiken in Vergleich gesetzt um die Kontinenz soziotechnologischer Strukturen aufzuweisen. Während ein Teil der untersuchten Werke keine direkte Relation zu den verglichenen Technologien aufweist, sondern sie in einer Nähe der beschriebenen sozialen Verhältnisse ihres Gebrauchs gestellt werden, lässt sich ein anderer Teil in Äußerungen von Personen in der technologischen Entwicklung des Internets wiederfinden. Über die Ideengeschichte des Internets hinweg bis zu dessen gegenwärtigen Ausformungen wurde ein Glaube an ein grundlegendes Prinzip der Kybernetik, aus Steigerung der Kommunikation und Konnektivität allgemeine Effizienz hervorzubringen, gefunden. Dieser von Internetpionieren und in Science-Fiction Werken formulierter Traum, so das Fazit, kann im Kontext des entstandenen Platformkapitalismus jedoch nicht als erfüllt angesehen werden.

barriers

description: This deliverable presents the TOOP pilot participants’ perception of the key barriers and drivers for the cross-border implementation of the once-only principle (OOP), which were studied on the basis of a literature review, survey, focus group interviews and workshops. In regards to legal challenges, key concerns for cross-border OOP implementation include meeting the requirements of lawfulness and compliance, legal value and validity of data exchanged, privacy, data protection and protecting confidentiality. Key technical barriers are found around technical and semantic interoperability. The study also identified that reluctance to change existing systems may act as a barrier; it is therefore expected that the architecture for cross-border OOP is compatible with existing national solutions. Organisational and political barriers relate to organisational inertia, low political prioritisation of the OOP, multiple stakeholders and interests, limited resources, organisational interoperability and different pricing policies. Last but not least, demonstrating the benefits for businesses and public administrations is perceived very important.
Does a strong particle accelerator arise very close to the light cylinder in a pulsar magnetosphere?

description: We examine if an efficient particle acceleration takes place by a magnetic-field-aligned electric field near the light cylinder in a rotating neutron star magnetosphere. Constructing the electric current density with the actual motion of collision-less plasmas, we express the rotationally induced, Goldreich-Julian charge density as a function of position. It is demonstrated that the 'light cylinder gap', which emits very high energy photons via curvature process by virtue of a strong magnetic-field-aligned electric field very close to the light cylinder, will not arise in an actual pulsar magnetosphere.

description: We report on a study of the dijet invariant-mass distribution in events with one identified lepton, a significant imbalance in the total event transverse momentum, and two jets. This distribution is sensitive to the possible production of a new particle in association with a $W$ boson, where the boson decays leptonically. We use the full data set of proton-antiproton collisions at 1.96 TeV center-of-mass energy collected by the Collider Detector at the Fermilab Tevatron and corresponding to an integrated luminosity of 8.9 fb$^{-1}$. The data are found to be consistent with standard-model expectations, and a 95$\%$ confidence level upper limit is set on the cross section for a $W$ boson produced in association with a new particle decaying into two jets.

description: Abstract: Background and purpose: Neonatal hyperbilirubinemia, also known as neonatal jaun-dice, is a common and frequent clinical condition with a complex etiology that can lead to brain damage in severe cases. Early recognition of hyperbilirubinemia and timely intervention and treatment can help reduce the occurrence of sequelae. This study was conducted to identify whether the gut microbiota composition can distinguish neonates with hyperbilirubinemia. Methods: Meconium samples were collected from 69 neonates with neonatal jaundice (NJ) and 69 age- and sex-matched neonates without clinically significant jaundice (healthy controls; HCs) for 16S rRNA gene sequencing and microbiome analysis. Results: Compared with HCs, the Chao 1 richness index of the gut microbiota was significantly decreased in the NJ group. The relative abundance of the probiotic gut bacterium, Lactobacillus, was significantly lower in the NJ group than in the HC group, whereas the abundances of potentially harmful gut bacteria, such as Esche-richia coli and Staphylococcus, were significantly higher in the NJ group than in HCs. Correlation of the gut microbiota and clinical indicators revealed a positive correlation between Escherichia coli/Staphylococcus and serum total bilirubin levels. Finally, the results of a random forest ma-chine-learning method to evaluate the possibility of using NJ-associated gut microbiota composi-tions as potential NJ biomarkers revealed an area under the curve of 96.88%. Conclusions: The abundances of Escherichia coli and Staphylococcus were positively correlated with serum total bili-rubin levels. Hence, the gut microbiota composition is a potential biomarker of NJ.

description: A search for laser light from the directions of Alpha Centauri A and B was performed by examining 15362 optical, high-resolution spectra obtained between 2004 and 2018. None of the spectra exhibit laser emission lines. The threshold was 10% of the continuum intensity of the spectra of both stars at all wavelengths between 3850 and 6900 Å. This search would have revealed optical laser light from the directions of Alpha Cen B if the laser had a power at least 1.4 to 5.4 MW (depending on wavelength) and was positioned within the 1 arcsecond field of view (projecting to 1.3 AU), for a benchmark 10-meter laser launcher. For Alpha Cen A, the laser power must be 3 times greater for detection. Lasers of smaller aperture would also have been detected but would require more power. Considering all optical surveys, a growing desert is emerging in the search for extraterrestrial technology.

description: Quantum entanglement is notorious for being a very fragile resource. Significant efforts have been put into the study of entanglement degradation in the presence of a realistic noisy environment. Here, we present a theoretical and an experimental study of the decoherence properties of entangled pairs of qubits. The entanglement dynamics of maximally entangled qubit pairs is shown to be related in a simple way to the noise representation in the Bloch sphere picture. We derive the entanglement level in the case when both qubits are transmitted through any arbitrary unital Pauli channel, and compared it to the case when the channel is applied only to one of the qubits. The dynamics of both cases was verified experimentally using an all-optical setup. We further investigated the evolution of partially entangled initial states. Different dynamics was observed for initial mixed and pure states of the same entanglement level.

description: Chicken (Gallus gallus domesticus) as one of the most economically important farm animals plays a major role in human food production and has been widely used as a key animal model that is presumed to be typical of avian and generally applicable to mammals in studies of developmental biology, virology, oncogenesis, and immunology. To get a better understanding of avian biology, global analysis of gene expression across multiple tissues is needed, which will aid genome annotation and support functional annotation of avian genes. We present a large-scale RNA-Seq dataset representing all the major organ systems from adult Lohmann White domesticus chickens. An open-access chicken tissue gene expression atlas (TGEA) (https://chickenatlas.avianscu.com/) is presented based on the expression of 224 samples across 38 well-defined chicken tissues. Network-based cluster analysis of this dataset grouped genes according to dimensionality reduction and whole-body co-expression patterns, which were used to infer the function of uncharacterized genes from their co-expression with genes of known function. We describe the distribution and tissue specificity of 21,430 genes present in the chicken gene expression atlas and assign those signatures, where possible, to specific tissue populations or pathways. To better understand the functions of GPCRs in avian, we quantified the transcript levels of 254 nonodorant GPCRs in all tissues. Cluster analysis placed many GPCRs into expected anatomical and functional groups and predicted previously unidentified roles for less-studied receptors. We also produced this atlas to analyze male and female mRNA expression profiles in chicken somatic and gonad tissues. Our analyses uncovered numerous cases of somatic sex-biased mRNA expression, with the largest proportion found in the chicken pineal body, pituitary, and liver. This high-resolution gene expression atlas for chickens is, to our knowledge, the largest transcriptomic dataset of any avian to date. It provides a resource to improve the annotation of the current reference genome for chicken, presenting a model transcriptome for avian, and can be used as a resource for predicting roles for incompletely characterized GPCRs, exploring sex-biased specific gene expression, and for other purposes.

description: Point process is the dominant paradigm for modeling event sequences occurring at irregular intervals. In this paper we aim at modeling latent dynamics of event propagation in graph, where the event sequence propagates in a directed weighted graph whose nodes represent event marks (e.g., event types). Most existing works have only considered encoding sequential event history into event representation and ignored the information from the latent graph structure. Besides they also suffer from poor model explainability, i.e., failing to uncover causal influence across a wide variety of nodes. To address these problems, we propose a Graph Regularized Point Process (GRPP) that can be decomposed into: 1) a graph propagation model that characterizes the event interactions across nodes with neighbors and inductively learns node representations; 2) a temporal attentive intensity model, whose excitation and time decay factors of past events on the current event are constructed via the contextualization of the node embedding. Moreover, by applying a graph regularization method, GRPP provides model interpretability by uncovering influence strengths between nodes. Numerical experiments on various datasets show that GRPP outperforms existing models on both the propagation time and node prediction by notable margins.

Did Gamma Ray Burst Induce Cambrian Explosion?

description: One longstanding mystery in bio-evolution since Darwin's time is the origin of the Cambrian explosion that happened around 540 million years ago (Mya), where an extremely rapid increase of species occurred. Here we suggest that a nearby GRB event ~500 parsecs away, which should occur about once per 5 Gy, might have triggered the Cambrian explosion. Due to a relatively lower cross section and the conservation of photon number in Compton scattering, a substantial fraction of the GRB photons can reach the sea level and would induce DNA mutations in organisms protected by a shallow layer of water or soil, thus expediting the bio-diversification. This possibility of inducing genetic mutations is unique among all candidate sources for major incidents in the history of bio-evolution. A possible evidence would be the anomalous abundance of certain nuclear isotopes with long half-lives transmuted by the GRB photons in geological records from the Cambrian period. Our notion also imposes constraints on the evolution of exoplanet organisms and the migration of panspermia.

legal landscape

description: This deliverable includes an inventory of the legal landscape and the regulations (both existing and emerging) that will have an impact on TOOP pilot activities across the Pilot Areas. It focuses on the legal drivers and barriers and explains how these barriers will be addressed within the context of TOOP. The overall structure and logic of the deliverable emerges from the need to ensure that TOOP: Complies with existing legislation and satisfies national legal and policy requirements; Provides a framework that can be applied to other pilots outside the context of TOOP (i.e. to ensure that the solution approach can be generalised to other once-only use cases); Is in line with emerging legislation on the once-only principle, including specifically the recently proposed Single Digital Gateway Regulation. In order to meet these objectives, this deliverable firstly identifies key legal principles with a basis in EU law, in order to identify horizontally applicable rules that govern the application of the once-only principle, and to create a legal assessment framework that allows legal barriers and challenges to be identified in any once-only use case. Secondly, it identifies and describes specific applicable legislation per pilot area in order to identify concrete legal requirements for the execution of the pilots. In practical terms, this can be understood as the application of the legal assessment framework to the three selected pilot areas. Thirdly, it proposes a legal solution framework (i.e. a set of legal tools) that can be applied in the three pilot areas to ensure that TOOP operates in compliance with existing law. The next steps, which are not yet fully developed in the present report, although an initial outline is provided, will be to instantiate the toolbox, i.e. to draft specific framework agreements, terms and conditions and policies that can be used in the actual development and roll-out of the pilots, which will be created in cooperation with pilot leaders. These texts are not incorporated in this deliverable, since the motivational scenarios of the pilots are still under development, but will be reported on as a part of D2.13 (sustainability plan). In addition, in the course of the TOOP project the legal drivers and barriers are reiterated and re-evaluated within D2.13 (sustainability plan), based on the experiences in the pilots, in order to ensure the long-term usability of TOOP outputs, taking into account the development of the Single Digital Gateway Regulation in the course of the project.
