description: ObjectiveTo examine changes in arterial blood pressure (ABP) after birth in extremely preterm infants.Study DesignProspective observational study of infants 230/7 – 266/7 weeks gestational age (GA). Antihypotensive therapy use and ABP measurements were recorded for the first 24 hours.ResultsA cohort of 367 infants had 18,709 ABP measurements recorded. ABP decreased for the first three hours, reached a nadir at 4 – 5 hours, then increased at an average rate of 0.2 mmHg / hour. The rise in ABP from hour 4 – 24 was similar for untreated infants (n=164) and infants given any antihypotensive therapy (n=203), a fluid bolus (n=135), or dopamine (n=92). GA specific trends were similar. ABP tended to be lower as GA decreased, but varied widely at each GA.ConclusionArterial blood pressure increased spontaneously over the first 24 postnatal hours for extremely preterm infants. The rate of rise in ABP did not change with antihypotensive therapy.

description: 2018 - 2019
description: The research activity, described in this Ph. D. thesis, was dedicated to the development of a novel carbon black (CB) primary particle model, with accurate morphology, to be used in coarse-grained (CG) molecular dynamics (MD) simulations. In particular, systems containing carbon black nanoparticles embedded in melts of polyethylene (PE) of varying molecular weigth (Mw), have been simulated, using a multiscale approach starting from the atomistic to the coarse-grained level. Simulations were performed either in mono and bidisperse PE melts, and in presence of either graphite or carbon black nanoparticle. The results obtained show that in bidisperse PE melts, a phase separation of the polymer takes place at the interface with the fillers, with the low Mw fraction being the most abundant one. The driving force for this phase separation has been proved to be entropical in nature, and greatly influenced by the shape and morphology of the filler (graphite or CB). These findings can help to understand experimental results and to address improvement of the dispersion of CB fillers in polyethylene matrices. Another part of the Ph. D. has been dedicated to the development of an all-atom model of 2-vinyl pyridine polymer, since no models were available in the literature, for the use in molecular dynamics simulations.

description: One of the most mysterious astrophysical states is the common envelope (CE) phase of binary evolution, in which two stars are enshrouded by the envelope shed by one of them. Interactions between the stars and the envelope shrinks the orbit. The CE can lead to mergers or to a subsequent phase of interactions. Mergers may involve any combination of two compact objects and/or stars. Some involving white dwarfs, may produce Type Ia supernovae, while merging neutron stars may yield gamma-ray bursts, and merging compact objects of all kinds produce gravitational radiation. Since CEs can arise from a variety of different initial conditions, and due to the complexity of the processes involved, it is difficult to predict their end states. When many systems are being considered, as in population synthesis calculations, conservation principles are generally employed. Here we use angular momentum in a new way to derive a simple expression for the final orbital separation. This method provides advantages for the study of binaries and is particularly well-suited to higher order multiples, now considered to be important in the genesis of potential mergers. Here we focus on CEs in binaries, and the follow-up paper extends our formalism to multiple star systems within which a CE occurs.

description: A disturbed diurnal blood pressure profile is one of the most important risk factors of cardiovascular diseases. This review analyzes the use of simultaneous diurnal ambulatory blood pressure monitoring (ABPM) and motion activity monitoring (actigraphy) to obtain additional information for correct interpretation of ABPM results in clinically significant decision-making. The article considers practical aspects of actigraphy in expert ABPM for clock-independent calculation of the parameters of nighttime and daytime blood pressure (BP); detection of BP changes during sleep; connection with respiratory disturbances during sleep, motion activity, and body position; and sleep deprivation in shift workers. Original illustrations of simultaneous ABPM and actigraphy are provided.
description: Ein gestörtes tageszeitabhängiges Blutdruckprofil ist einer der wichtigsten Risikofaktoren für Herz-Kreislauf-Erkrankungen. In der vorliegenden Übersichtsarbeit wird die Bedeutung der gleichzeitigen Durchführung des ambulanten Blutdruckmonitorings (ABPM) und der Messung der Bewegungsaktivität (Aktigraphie) beschrieben. Durch die Aktigraphie werden zusätzliche Informationen für die korrekte Interpretation des ABPM gewonnen, die zu klinisch relevanten Entscheidungen beitragen. In diesem Artikel werden praktische Aspekte der Aktigraphie in der Anwendung durch Experten bei ABPM zur uhrzeitunabhängigen Berechnung der Parameter des Blutdrucks (BP) am Tag und in der Nacht betrachtet, zur Erkennung von BP-Veränderungen während des Schlafs, zum Zusammenhang mit Atmungsstörungen während des Schlafs, zur Bewegungsaktivität und zur Körperposition sowie zum Schlafentzug bei Schichtarbeitern. Originalabbildungen der durchgeführten ABPM und Aktigraphie illustrieren exemplarisch die Daten.

description: Given a perfect field $k$ of characteristic $p>0$, a smooth proper $k$-scheme $Y$, a crystal $E$ on $Y$ relative to $W(k)$ and a finite group $G$ acting on $Y$ and $E$, we show that, viewed as virtual $k[G]$-module, the reduction modulo $p$ of the crystalline cohomology of $E$ is the de Rham cohomology of $E$ modulo $p$. On the way we prove a base change theorem for the virtual $G$-representions associated with $G$-equivariant objects in the derived category of $W(k)$-modules.

description: This article describes recommended activities of social workers, psychologists and psychiatric staff within the neonatal intensive care unit (NICU). NICU mental health professionals (NMHPs) should interact with all NICU parents in providing emotional support, screening, education, psychotherapy and teleservices for families. NMHPs should also offer educational and emotional support for the NICU health-care staff. NMHPs should function at all levels of layered care delivered to NICU parents. Methods of screening for emotional distress are described, as well as evidence for the benefits of peer-to-peer support and psychotherapy delivered in the NICU. In the ideal NICU, care for the emotional and educational needs of NICU parents are outcomes equal in importance to the health and development of their babies. Whenever possible, NMHPs should be involved with parents from the antepartum period through after discharge.

description: Post-modernist film adaptations of Shakespeare often deconstruct the Shakespeare myth, as do Baz Luhrmann’s prolific Romeo + Juliet (1996), Lloyd Kaufman’s lowbudget Tromeo and Juliet (1996) and Fumitoshi Oizaki’s anime production, Romeo × Juliet (2007), all of which draw on pop pastiche. Reducing reality to an imitation of signs these films inflate signs that are deprived of their essence. Placing Romeo and Juliet into a world that continually references itself through an abundance of signs, these films ask how true, authentic love can be experienced.

description: Asking students to generate a prediction before presenting the correct answer is a popular instructional strategy. This study tested whether a person’s degree of confidence in a prediction is related to their curiosity and surprise regarding the answer. For a series of questions about numerical facts, participants (N = 29) generated predictions and rated their confidence in the prediction before seeing the correct answer. The increase in pupil size before viewing the correct answer was used as a physiological marker of curiosity, and the increase in pupil size after viewing the correct answer was used as a physiological marker of surprise. The results revealed that the pupillometric marker of curiosity was most pronounced if students were slightly more confident in their prediction than usual, and it was lower for predictions made with either very high or very low confidence. Furthermore, the results showed that high-confidence prediction errors and low-confidence correct responses yielded a pupillary surprise response, suggesting that highly unexpected results evoke surprise, independent of the correctness of the prediction. Together, results suggest that confidence in a prediction plays an important role in the occurrence of epistemic emotions such as curiosity and surprise.

description: Purpose Many start-ups do not survive the first few years of business. Previous studies suggest that networks play a role in start-ups' success, but this positive effect has limits. The purpose of this paper is to answer the call for a better understanding of the dark side of networks and the variables that condition variables' effect on the likelihood of start-ups' survival. Design/methodology/approach A longitudinal research design includes 139 start-ups (102 from Germany and 37 from Portugal) and a total of 252 participants. A generalized linear mixed model (GLMM)was applied to estimate all the coefficients, to test the mediation (H1), the moderation (H2) and the moderated mediation (H3) while considering the economic situation of the start-up (sales growth), start-ups' networking behavior, creativity orientation and ultimately the likelihood of survival. Findings Based on an empirical study from two different countries, the results show that effective networking is contingent on the start-up's economic situation and creative potential. Specifically, the results point to situations in which early sales growth may lead to external networking, which, in contexts of low creativity-oriented start-ups, can compromise the start-ups' success. Originality/value Based on the findings, the authors compare scenarios in which networking increases the chances for start-up survival with situations where networking can have adverse effects. This study highlights the importance of considering specific start-up parameters, such as start-ups' economic situation and level of creativity orientation, in the business venturing literature.
Tunable cylindrical shell as an element in acoustic metamaterial

description: Elastic cylindrical shells are fitted with an internal mechanism which is optimized so that, in the quasi-static regime, the combined system exhibits prescribed effective acoustic properties. The mechanism consists of a central mass supported by an axisymmetric distribution of elastic stiffeners. By appropriate selection of the mass and stiffness of the internal mechanism, the shell's effective acoustic properties (bulk modulus and density) can be tuned as desired. Subsonic flexural waves excited in the shell by the attachment of stiffeners are suppressed by including a sufficiently large number of such stiffeners. Effectiveness of the proposed metamaterial is demonstrated by matching the properties of a thin aluminum shell with a polymer insert to those of water. The scattering cross section in water is nearly zero over a broad range of frequencies at the lower end of the spectrum. By arranging the tuned shells in an array the resulting acoustic metamaterial is capable of steering waves. As an example, a cylindrical-to-plane wave lens is designed by varying the bulk modulus in the array according to the conformal mapping of a unit circle to a square.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Through the interaction of Higgs with heavy quarks in standard model, we have systematically studied and predicted the production of excited doubly heavy baryons based on non-relativistic QCD theory. The decay widths, differential distributions, and major theoretical uncertainties of the excited doubly heavy baryons via the process $H \rightarrow \langle QQ'\rangle[n] \rightarrow Ξ_{QQ'}+ \bar {Q'} + \bar {Q}$ are discussed in detail. The spin and color quantum number of the intermediate $P$-wave diquark state $\langle QQ'\rangle[n]$ can be $\langle cc\rangle[^{1}P_{1}]_{\mathbf{\bar 3}}$, $\langle cc\rangle[^{3}P_{J}]_{\mathbf{6}}$, $\langle bc\rangle[^{1}P_{1}]_{\mathbf{\bar 3}/ \mathbf{6}}$, $\langle bc\rangle[^{3}P_{J}]_{\mathbf{\bar 3}/ \mathbf{6}}$, $\langle bb \rangle[^{1}P_{1}]_{\mathbf{\bar 3}}$ and $\langle bb\rangle[^{3}P_{J}]_{\mathbf{6}}$, with $J=0, 1, 2$. The contributions from all summed $P$-wave states can be about $3.05\%$, $3.23\%$ and $2.19\%$ of the $S$-wave states for the production of $Ξ_{cc}$, $Ξ_{bc}$ and $Ξ_{bb}$, accordingly. Therefore, there will be about 0.41$\times10^4$ events of $Ξ_{cc}$, 6.35$\times10^4$ events of $Ξ_{bc}$ and 0.28$\times10^4$ events of $Ξ_{bb}$ produced per year at the HL-LHC, and a smaller number of events would be produced at the CEPC or ILC but with a cleaner background to be measured by the experiments.

Les enseignants, les infirmières et les médecins ont du mal à reconnaître et à traiter efficacement les situations de harcèlement. Les risques principaux pour ces adolescents sont la détresse psychique et la suicidalité. Le but de cette recension de littérature est de faire un état des lieux sur le sujet et de proposer des stratégies de préventions infirmières par le biais de la théorie de McGill. Méthode : Les bases de données PubMed et CINHAL ont permis de recenser 82 articles exploitables, après l’ajout de filtres. Neuf articlessont choisis pour ce travail aprèsune analyse critique avec les grilles de Fortin. Résultats : Trois à cinq élèves sur dix sont impliqués dans le harcèlement scolaire et/ou cyberharcèlement. Les symptômes dépressifs sont quatre fois plus présents chez les victimes des deux types de harcèlementque chez les non-victimes. Les victimes de harcèlement sont trois fois plus sujettes à considérer le suicide que les non-victimes.Des propositions de stratégies d’interventions infirmières ont pu être relevées. Conclusion : Les stratégies d’interventions ressorties sont l’apprentissage à travers la formation et l’implantation de programmes de prévention du suicide dans les écoles. Des recherches futures sont nécessaires, afin de faire un état des lieux national et européen, d’impliquer davantage la discipline infirmière et de mettre en place des interventions pour faire face à ce nouveau problème de santé publique.

description: The β-emitting 99Tc isotope is a high-yield fission product in 235U and 239Pu nuclear reactors, raising special concern in nuclear waste management due to its long half-life and the high mobility of pertechnetate (TcO4−). Under the conditions of deep nuclear waste repositories, Tc is retained through biotic and abiotic reduction of TcO4− to compounds like amorphous TcO2 ⋅ xH2O precipitates. It is generally accepted that these precipitates have linear (Tc(μ-O)2(H2O)2)n chains, with trans H2O. Although corresponding Tc−Tc and Tc−O distances have been obtained from extended X-ray absorption fine structure (EXAFS) spectroscopy, this structure is largely based on analogy with other compounds. Here, we combine density-functional theory with EXAFS measurements of fresh and aged samples to show that, instead, TcO2 ⋅ xH2O forms zigzag chains that undergo a slow aging process whereby they combine to form longer chains and, later, a tridimensional structure that might lead to a new TcO2 polymorph.

Objectifs : Donner des interventions infirmières précoces qui permettront au patient d’améliorer sa qualité de vie. Méthode : Pour la recherche d’articles scientifiques, les bases de données CINAHL et Pubmed ont été utilisées. Ceci a permis de sélectionner six articles qui ont été analysés à l’aide de deux grilles d’analyse issues du Fortin (2010). Ces articles ont été choisis en regardant la langue (français et anglais), la limite dans le temps (maximum dix ans) et la correspondance avec la question de recherche. Résultats : La synthèse des résultats a fait émerger les trois thèmes suivants : la qualité de vie, l’estime de soi et l’espoir. Discussion : L’articulation des résultats se fait avec la théorie de la gestion des symptômes. Le fait de minimiser les déficits fonctionnels, d’augmenter le niveau de dépendance, de soutenir les proches, faire des tournées infirmières privilégiant le confort et l’absence de péjoration de l’état de santé du patient ainsi que l’évaluation de l’estime de soi et la recherche d’une symptomatologie dépressive sont des interventions infirmières permettant de répondre à la question de recherche initiale. Conclusion : Ce travail permet aux infirmières d’avoir des pistes pour des interventions pratiques qui aideront le patient à améliorer sa qualité de vie. Le travail interdisciplinaire doit également être favorisé, ce qui permettra une prise en charge holistique du patient ayant subi un AVC.
Antiferromagnetic Heisenberg Model on the Icosahedron: Influence of Connectivity and the Transition from the Classical to the Quantum Limit

description: The antiferromagnetic Heisenberg model on the icosahedron, which consists of 20 edge-sharing triangles and belongs to the icosahedral $I_h$ symmetry group, presents unconventional properties at the classical and quantum level. These originate in the frustrated nature of the interactions between the spins. For classical spins the magnetization is discontinuous in a magnetic field. Here we examine the importance of the connectivity of the icosahedron for the appearance of the magnetization discontinuity, and also investigate the transition from the classical to the quantum limit. The influence of connectivity on the magnetic properties is revealed by considering the cluster as being made up of a closed strip of a triangular lattice with two additional spins attached. The classical magnetization discontinuity is shown to evolve continuously from the discontinuity effected by these two spins when they are uncoupled to the cluster. In the second part the transition from the classical to the quantum limit is examined by focusing on the low energy spectrum taking fully into account the spatial and the spin symmetry of the model in the characterization of the states. A symmetry analysis of the highly degenerate due to the connectivity lowest energy classical manifold identifies as its direct fingerprint the low energy quantum states for spin magnitude as low as $s=1$, with the latter following a tower of states behavior which relates to the icosahedron having a structure reminiscent of a depleted triangular lattice. The classical character of the AHM for small $s$ is also detected on the ground state energy and correlation functions. On the other hand the classical magnetization discontinuity in a field eventually disappears for small $s$, after a weak reentrant behavior.

Résultats: Un certain nombre de mesures ont été élaborées pour améliorer la collaboration interdisciplinaire: l’implantation de nouveaux guidelines et protocoles, l’intervention d’un médecin de transition ou d’une équipe infirmière spécialisée/psychiatre, l’encouragement à la participation individuelle pour favoriser un meilleur fonctionnement d’équipe, la création de nouvelles équipes interdisciplinaires pour améliorer les soins et la réorganisation d’une équipe pour mieux s’adapter à la complexité des patients. Discussion: Alors que les recherches recommandent plusieurs interventions pour faire face aux différentes barrières à la collaboration, la rencontre de professionnels sur le terrain amène des éléments concrets et une contextualisation. Cependant, les mesures répertoriées sont difficilement généralisables étant donné la spécificité de chaque service.

description: In the standard asymptotic expansion of four dimensional static asymptotically flat spacetimes, the coefficient of the first subleading term of the lapse function can be identified with the mass of the spacetime. Using the Hamiltonian formalism we show that, in asymptotically locally anti-de Sitter spacetimes endowed with a scalar field, the mass can read off in the same way only when the boundary conditions are compatible with the asymptotic realization of the anti-de Sitter symmetry. In particular, this implies that some prescriptions for computing the mass of a hairy spacetime are not suitable when the scalar field breaks the asymptotic anti-de Sitter invariance.

description: Postpartum haemorrhage (PPH) is an obstetric emergency where timely identification and intervention is paramount. It is thus recommended that all women birth in, or next to, hospitals that are well-equipped with resources necessary for managing heavy bleeding. In the out-of-hospital setting, where these resources are inherently limited, the risk of mortality from PPH is significantly increased. Yet, no standardised guideline exists for managing this in the prehospital setting. A scoping review will hence be performed to map the available literature to identify the scope of knowledge on this topic, which will help with developing clinical practice guidelines.
Equitable proof-of-work mining rewards

Publisher: name: Imperial College London

description: We present Reward-All Nakamoto-Consensus (Reward-All), a Proof-of-Work cryptocurrency that rewards each miner with a number of coins that is directly proportional to its individual mining power, rather than in proportion to its relative share of the entire network’s mining power as done in Bitcoin. Unlike their Bitcoin counterparts, miners in Reward-All do not have to win the leader-election process to earn coins, and only lose earned coins after block reorganizations of a configurable minimum length occur. We present a detailed specification of Reward-All, along with a prototype implementation, and an evaluation of its practicality and eﬀiciency. Additionally, we provide an analysis of the security of Reward-All, where mining is modeled as a Markov Decision Process, and the advantages of optimal mining strategies are quantified. Under reasonable configurations, Reward-All achieves near-perfect incentive compatibility, and near-zero censorship susceptibility, for adversarial mining shares up to 45%, while retaining the same chain quality as Bitcoin’s Nakamoto Consensus (Nakamoto). However, Reward-All pays for these advantages with a regression in subversion gain resilience compared to Nakamoto. Furthermore, under Reward-All’s approach, the growth rate of the total coin supply correlates closely with the growth rate of mining power invested in the network. This enables miners to mint coins at a stable hash-based cost of production, and enables all rewarded coins to correspond to an approximately equal number of hashing attempts on average. Consequently, depending on the network transaction-fees, Reward-All improves miners’ waiting times for rewards, and incentivizes forming mining pools smaller than required in Bitcoin for an equal level of reward stability. Moreover, rewards in Reward-All exhibit significantly lower variance for non-majority miners compared to Nakamoto, enabling unprecedented reward stability.

description: Tumor necrosis factor-alpha (TNF-α) plays a central role in the molecular pathogenesis of periodontal disease. However, the epigenetic regulation attributable to microbial and inflammatory signals at the biofilm gingival interface are poorly understood. In this study, we investigated the DNA methylation alteration within the TNFA promoter in human gingival biopsies from different stages of periodontal disease, and explored the regulatory mechanism of TNFA transcription by DNA methylation.

description: Problématique : Les conséquences de l’apparition d’un locked-in syndrome (LIS) provoque un bouleversement total sur tous les aspects reliés à l’individu, impliquant l’établissement de stratégies d’adaptation, surtout au niveau de la communication. Objectif : Définir comment l’infirmier1 peut participer à l’établissement de stratégies de communication permettant au patient adulte atteint de LIS de retrouver une interaction avec son environnement. Méthode : Deux bases de données ont été utilisées pour la recherche des articles scientifiques qui ont permis l’élaboration de ce travail, CINAHL et Pubmed. Le LIS constituant un sujet peu recensé par la littérature en raison de sa faible incidence, l’« effet boule de neige » par l’intermédiaire de GoogleScholar a permis de compléter les recherches. De plus, deux articles de neuro-réhabilitation ont été ajoutés afin d’étayer les résultats. Résultats : La synthèse des résultats de huit articles préalablement sélectionnés a permis d’identifier trois thèmes principaux : les capacités motrices et cognitives, le développement de la communication et l’utilisation de moyens alternatifs et la qualité de vie. Discussion : Le rôle infirmier est présent et nécessaire au sein de la réhabilitation. De nombreux outils d’aide à la communication existent et leur développement fait partie intégrante de tout programme de réhabilitation. Le rétablissement de la communication a un impact considérable sur la qualité de vie du patient LIS, et représente ainsi un élément essentiel au maintien de cette dernière.
Noncoercive nonlinear elliptic equations in unbounded domains

description: This research thesis is mainly devoted to the study of noncoercive Dirich let problems with discontinuous coefficients in unbounded domains. The presence of the noncoercive operator does not allow us to use classical the orems to achieve existence results. Further complications arise as a conse quence of the unboundedness of the domain that yields to the lack of com pactness results. To overcome these difficulties, on one hand we approximate the solution of the problem by the solutions of suitable coercive nonlinear Dirichlet problems. On the other hand, we introduce suitable Sobolev spaces where opportune compactness results hold. [edited by Author]
Convergence and variance reduction for stochastic differential equations in sampling and optimisation
Creators: name: Chak, Martin
Publisher: name: Imperial College London
Year: 2022

description: Three problems that are linked by way of motivation are addressed in this work. In the first part of the thesis, we study the generalised Langevin equation for simulated annealing with the underlying goal of improving continuous-time dynamics for the problem of global optimisation of nonconvex functions. The main result in this part is on the convergence to the global optimum, which is shown using techniques from hypocoercivity given suitable assumptions on the nonconvex function. Alongside, we investigate numerically the problem of parameter tuning in the continuous-time equation. In the second part of the thesis, this last problem is addressed rigorously for the underdamped Langevin dynamics. In particular, a systematic procedure for finding the optimal friction matrix in the sampling problem is presented. We give an expression for the gradient of the asymptotic variance in terms of solutions to Poisson equations and present a working algorithm for approximating its value. Lastly, regularity of an associated semigroup, twice differentiable-in-space solutions to the Kolmogorov equation and weak numerical convergence rates of order one are shown for a class of stochastic differential equations with superlinearly growing, non-globally monotone coefficients. In the relation to the previous part, the results allow the use of Poisson equations for variations of Langevin dynamics not permissible before.

Towards optimal operation of power systems with high IBR penetration: a stability-constrained optimization approach
Creators: name: Chu, Zhongda
Publisher: name: Imperial College London
Year: 2022

description: Renewable Energy Sources (RES) have been massively integrated into the modern electric power system in the past few decades due to the environmental and sustainability concerns throughout the world. As a result, the power electronic converters are anticipated to acquire a steadily increasing role as they are the key element for the interface between RES and the grid. However, owing to the intermittency of the RES and the distinguished features of the Inverter-Based Resources (IBRs). The main focus of this thesis is to develop optimal system operation strategies to maintain the security and stability of the grid while considering the fast and accurate control of the IBR units. To achieve this, we investigate challenges in different areas. Regarding system frequency and low inertia issues, the main challenges are the incorporation of differential equation-based frequency dynamics into algebraic equation-based optimization problem as well as the optimal utilization of the frequency support from different sources. We first target on the optimal system scheduling on a transmission system level to achieve system operation cost minimization while maintaining the frequency security. In addition, the frequency stability problem in microgrids after unintentional islanding events is also studied. We consider the frequency support from WTs, PV and storage systems as well as noncritical load shedding to ensure the microgrid frequency security after unintentional islanding events. Furthermore, a SCC-constrained Unit Commitment (UC) model is developed, maintaining a minimum SCC level at different locations in the system such that enough reactive current could be supplied during the fault to trigger the protection devices and maintain the post-fault voltages. Moreover, the static voltage stability in systems with high IBR penetration is also investigated considering the interactions among the IBR units and their reactive power support capability within rating limits.
