description: Background: Score-based survival prediction in patients with advanced heart failure (HF) is complicated. Easy-to-use prognostication tools could inform clinical decision-making and palliative care delivery. Objective: To compare the prognostic utility of the Seattle HF model (SHFM), the surprise question (SQ), and the number of HF hospitalizations (NoH) within the last 12 months for predicting 1-year survival in patients with advanced HF. Methods: We retrospectively analyzed data from a cluster-randomized controlled trial of advanced HF patients, predominantly with reduced ejection fraction. Primary outcome was the prognostic discrimination of SHFM, SQ (“Would you be surprised if this patient were to die within 1 year?”) answered by HF cardiologists, and NoH, assessed by receiver operating characteristic (ROC) curve analysis. Optimal cut-offs were calculated using Youden’s index (SHFM: <86% predicted 1-year survival; NoH ≥ 2). Results: Of 535 subjects, 82 (15.3%) had died after 1-year of follow-up. SHFM, SQ, and NoH yielded a similar area under the ROC curve [SHFM: 0.65 (0.60–0.71 95% CI); SQ: 0.58 (0.54–0.63 95% CI); NoH: 0.56 (0.50–0.62 95% CI)] and similar sensitivity [SHFM: 0.76 (0.65–0.84 95% CI); SQ: 0.84 (0.74–0.91 95% CI); NoH: 0.56 (0.45–0.67 95% CI)]. As compared to SHFM, SQ had lower specificity [SQ: 0.33 (0.28–0.37 95% CI) vs. SHFM: 0.55 (0.50–0.60 95% CI)] while NoH had similar specificity [0.56 (0.51–0.61 95% CI)]. SQ combined with NoH showed significantly higher specificity [0.68 (0.64–0.73 95% CI)]. Conclusion: SQ and NoH yielded comparable utility to SHFM for 1-year survival prediction among advanced HF patients, are easy-to-use and could inform bedside decision-making.

Alle origini del rogo votivo e della metallurgia alpina Il culto del fuoco nell?Et� del Rame nel caso del Pigloner Kopf
Creators: name: Oberrauch, Hanns
Publisher: name: Universit� degli studi di Trento
Year: 2021

description: The archaeological site Pigloner Kopf (Vadena/Pfatten, South Tyrol, Italy) has revealed unexpected elements related to the local Bell Beaker culture, like the local production of shaft-hole axes, typologically linked to the Balkans and the Danube region. The site also shows the oldest evidence of ritual burnt offerings in the Eastern Alps. The mostly burnt animal bones, cereals, flint tools and fragments of pottery could be interpreted as the remains of a rock sanctuary with burnt offerings. The site can be considered as a prototype of the alpine places of worship and mountain sanctuaries. These burning rituals were practised from the beginning of the Bronze Age until the late Roman Empire. The aim of the paper is to present the results of the study of materials and their analyses, focussing on the metallurgical industry, composed mostly by objects produced with local copper, like 10 miniaturised shaft-hole axes, 7 awls and a pin and also by imported objects like a dagger blade and spiral ornaments. The deposition of copper tools in hoards in association with burnt offerings suggest a ritual interpretation of the site, dated to the late Copper Age with Bell Beaker elements in lithics and pottery.

description: The rising rate of preprints and publications, combined with persistent inadequate reporting practices and problems with study design and execution, have strained the traditional peer review system. Automated screening tools could potentially enhance peer review by helping authors, journal editors, and reviewers to identify beneficial practices and common problems in preprints or submitted manuscripts. Tools can screen many papers quickly, and may be particularly helpful in assessing compliance with journal policies and with straightforward items in reporting guidelines. However, existing tools cannot understand or interpret the paper in the context of the scientific literature. Tools cannot yet determine whether the methods used are suitable to answer the research question, or whether the data support the authors' conclusions. Editors and peer reviewers are essential for assessing journal fit and the overall quality of a paper, including the experimental design, the soundness of the study's conclusions, potential impact and innovation. Automated screening tools cannot replace peer review, but may aid authors, reviewers, and editors in improving scientific papers. Strategies for responsible use of automated tools in peer review may include setting performance criteria for tools, transparently reporting tool performance and use, and training users to interpret reports.

Stabilisation of therapeutic proteins using surface engineering and ionic liquids
Creators: name: Bui-Le, Liem
Publisher: name: Imperial College London
Year: 2020

description: The temperature sensitivity of proteins hinders the bioavailability and safety of therapeutic antibodies and vaccines. These biomolecules require storage at 2 – 8 °C from manufacturing to administration to prevent thermal degradation, known as the ‘cold chain’. However, the cold chain cannot be implemented in resource-limited areas with inadequate infrastructure. Stabilising proteins at room temperature would break the ‘cold chain’ and allow life-saving treatments to be distributed to resource-limited areas, where infectious diseases can account for over half the mortality rate. In this thesis, surface engineering and ionic liquids were used to improve the storage-lifetime of proteins (Chapter 3 – 5). Surface engineering can improve thermal stability whilst increasing solubility in ionic liquids; however, ionic liquid-protein interactions are misapprehended and often contradictory. Therefore, a holistic multi-technique framework — a combination of scattering and spectroscopic techniques — was developed on the green fluorescent protein and avidin as an archetypal probe to decipher the complex interactions (Chapter 3). The framework revealed the effect of ionic liquid anion nuances on protein structure and stability. Surface engineering has been applied for the first time to ligand‐binding proteins (Chapter 4) and antibodies (Chapter 5) to create a thermally stable biofluid. Surface-engineering of avidin revealed a nanoconjugate with retention of activity and a half denaturation temperature of 139.0 °C and observed no denaturation after equivalent storage at 25 °C for 160 days. For the surface-engineering of antibodies, a maximum half denaturation temperature of 198.2 °C, while retaining binding activity, revealing that the high stability was transferable. However, a potential trade-off between thermal stability and bioavailability was observed. Regardless, the unprecedented transferable thermal stability presented herein provides a blueprint for stabilising vaccine candidates, avoiding the use of ultra-low temperature freezers. The stabilisation of these vaccines will be necessary for their dissemination to the unimmunised population to prevent or end a pandemic.

description: This paper compares and contrasts the emission of two high nulling fraction pulsars, PSRs J1738-2330 and J1752+2359. In both pulsars the emission bursts appear in a quasi-periodic fashion with typical separations of several hundred pulses, and in J1738-2330 there is evidence of two underlying periodicities with memory persisting for at least 11 bursts. By contrast, in J1752+2359 the pattern coherence is rapidly lost and the burst/null lengths appear to be selected randomly from their respective quasi-normal distributions. The typical emission bursts of J1738-2330 exhibit a steady exponential decay of on-pulse energy accompanied by a flickering emission characterized by short frequent nulls towards their end. In the bursts of J1752+2359 the flickering is absent, the decay more pronounced and the energy released during each bright phase is approximately constant. Unlike J1738-2330, the average profiles for the first and the last pulses of J1752+2359 bursts differ slightly from the pulsar's overall profile, hinting at differences between the two pulsars in their transitions from null to burst state (and vice-versa). During its long null phases, J1752+2359 is found to emit random weak inter-burst pulses (IBPs) whose profile peak is somewhat offset with respect to the overall average profile. Such pulses have no equivalent in J1738-2330 or in any known pulsar hitherto. They may pervade the entire emission of this pulsar and have a separate physical origin to normal pulses. On the basis of our comparison we conclude that a pulsar's nulling fraction, even when high, remains a poor guide to its detailed subpulse behaviour, as previously found for pulsars with small nulling fractions.

description: In this paper, we present the first general solution to the automatic reconfiguration problem of timed discrete-event systems. We extend the recursive forcible backtracking approach which had been already solved the automatic reconfiguration problem of untimed discrete-event systems. In particular, we first solve the timed centralized reconfiguration problem using a specific timed eligibility set. Then, we study the identity between the solutions to an arbitrary timed centralized reconfiguration problem and its corresponding decentralized version. It turns out that the solutions to both cases are identical to each other. So, the solution obtained by the proposed theory is interestingly invariant to systematic distributions.

description: Indigo, one of the most ancient and abundant dyes in human history, has recently emerged as a potential functional motif due to its intriguing photochemical properties. This review aims to provide insights into both the preparation of these molecules and their utilization in molecular systems. First, the synthesis of the indigo core as well as available methods to derivatize indigo are described to outline synthetic strategies to build the desired molecular structures. Then, the photochemical behavior of indigos is discussed, with particular focus on E-Z photoisomerization and photoinduced electron transfer. Connections between the molecular structures and their photochemical properties are highlighted and serve as guiding principles for designing indigos to be applied as photoresponsive tools.

description: Multivariate data that combine binary, categorical, count and continuous outcomes are common in the social and health sciences. We propose a semiparametric Bayesian latent variable model for multivariate data of arbitrary type that does not require specification of conditional distributions. Drawing on the extended rank likelihood method by Hoff [Ann. Appl. Stat. 1 (2007) 265-283], we develop a semiparametric approach for latent variable modeling with mixed outcomes and propose associated Markov chain Monte Carlo estimation methods. Motivated by cognitive testing data, we focus on bifactor models, a special case of factor analysis. We employ our semiparametric Bayesian latent variable model to investigate the association between cognitive outcomes and MRI-measured regional brain volumes.

description: What role do affective states play in cognition? In this work, we use contemporary cognitive research to address this question. We first de-fine emotions with respect to the much wider class of affective states, showing how each of them can affect our judgement. We then describe a poorly investigated sub-class of affective states called ?epistemic feel-ings?, which make a particularly strong impact on our thinking process-es. We then turn to consider a subclinical condition, ?alexithymia?, characterized by an inability to perceive real emotions. Alexithymics have normal intelligence, however they have impaired awareness of their own emotions. By analyzing the skills alexithymics preserve and the difficulties they face, we show that numerous fundamental social skills ? for understanding, evaluating and judging human behavior ? rely deeply on emotions.
Clustering of Local Group distances: publication bias or correlated measurements? I. The Large Magellanic Cloud

description: The distance to the Large Magellanic Cloud (LMC) represents a key local rung of the extragalactic distance ladder. Yet, the galaxy's distance modulus has long been an issue of contention, in particular in view of claims that most newly determined distance moduli cluster tightly - and with a small spread - around the "canonical" distance modulus, (m-M)_0 = 18.50 mag. We compiled 233 separate LMC distance determinations published between 1990 and 2013. Our analysis of the individual distance moduli, as well as of their two-year means and standard deviations resulting from this largest data set of LMC distance moduli available to date, focuses specifically on Cepheid and RR Lyrae variable-star tracer populations, as well as on distance estimates based on features in the observational Hertzsprung-Russell diagram. We conclude that strong publication bias is unlikely to have been the main driver of the majority of published LMC distance moduli. However, for a given distance tracer, the body of publications leading to the tightly clustered distances is based on highly non-independent tracer samples and analysis methods, hence leading to significant correlations among the LMC distances reported in subsequent articles. Based on a careful, weighted combination, in a statistical sense, of the main stellar population tracers, we recommend that a slightly adjusted canonical distance modulus of (m-M)_0 = 18.49 +- 0.09 mag be used for all practical purposes that require a general distance scale without the need for accuracies of better than a few percent.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: One of the outstanding problems of classical celestial mechanics was the restricted 3-body prob- lem, in which a planetoid of small mass is subject to the Newtonian attraction of two celestial bodies of large mass, as it occurs, for example, in the sun-earth-moon system. On the other hand, over the last decades, a systematic investigation of quantum corrections to the Newtonian potential has been carried out in the literature on quantum gravity. The present paper studies the effect of these tiny quantum corrections on the evaluation of equilibrium points. It is shown that, despite the extreme smallness of the corrections, there exists no choice of sign of these corrections for which all qualitative features of the restricted 3-body problem in Newtonian theory remain unaffected. Moreover, first-order stability of equilibrium points is characterized by solving a pair of algebraic equations of fifth degree, where some coefficients depend on the Planck length. The coordinates of stable equilibrium points are slightly changed with respect to Newtonian theory, because the planetoid is no longer at equal distance from the two bodies of large mass. The effect is conceptually interesting but too small to be observed, at least for the restricted 3-body problems available in the solar system.

Mechanics of biofunctionalised bioconducting microfibres for the treatment of spinal cord injury
Creators: name: Corridori, Ilaria
Publisher: name: Universit� degli studi di Trento
Year: 2021

description: Spinal cord injury causes the partial or total loss of the anatomical and functional continuity of the spinal cord tissue, leading to the damage of the organs controlled by nerves that branch off downstream the injury. This thesis analyses the mechanics of two possible treatments based on two different approaches: intraspinal microstimulation (ISMS) and tissue engineering. These two approaches have a common rationale, the delivery of electrical stimuli to the injured spinal cord. In the literature, the feasibility of the electrodes for ISMS is often limited to the analysis of stiffness. The mechanical validation of the device is then focused on the step after the in vivo implantation, considering the interplay with the surrounding tissue. In this work, the mechanical performance of an innovative intraspinal microstimulation device is evaluated thoroughly before the in vivo step, to avoid the waste of material, animals, and time. The study involves the characterisation of the single components (electrodes), prototypes, and possible failure mechanisms. A work on silk fibroin hydrogels for the regeneration of the spinal cord is also presented. Silk fibroin is a highly versatile material for biomedical purposes, and thus largely used in tissue engineering. Moreover, it has piezolectric properties subjected to micro and nanostructure. Given the proven benefits of electrical stimulation in the regeneration of the spinal cord after injury, different approaches studied in literature often require the use of external devices to generate electrical stimuli. This thesis aims to study the mechanical properties of silk fibroin hydrogels obtained by applying an electric field to silk fibroin solutions, to investigate the eventual increase of the microstructure orientation and consequent improvement of the piezoelectric effects of fibroin.

description: The petroleum industry is often faced with accidental spills and discharges that pollute valuable natural resources such as soil. The purpose of this study was to assess bioremediation potential of an on-site landfarming unit (LU), a highly economical solution that complies with the zero-waste policy, for bioremediation of the contaminated soil after an actual diesel fuel leakage in a fuel depot. The first aim was to evaluate the effects of different climates on hydrocarbon bioremediation. For this reason, a part of the contaminated soil was moved from the initial location with a sub-Mediterranean climate to an LU at another location with a temperate continental climate. Our results demonstrated that remediation in sub-Mediterranean climate is less effective than the remediation in a temperate continental climate. The second aim of this study was to evaluate the effect of different plant species on the microbial population during bioremediation. For that purpose, 365-day monitoring of phospholipid fatty acids (PLFA) was performed. Our results support the hypothesis that plant-assisted bioremediation can diminish toxic effects of diesel-polluted soil and that the changes in plant species during bioremediation cause changes in the microbial population. The main objective of this study was to implement a landfarming bioremediation technique after an actual diesel fuel pollution in the sub-Mediterranean climate and diminish toxic effects of pollutants in soil. Since soil bioremediation is performed by soil microorganisms, their communities are primarily affected by the growing vegetation and climatic conditions. For future bioremediation strategies or ex situ approaches, it is crucial to assess the influence of a specific climate on the degradation rate of hydrocarbons in soil and select the most efficient plant species for this purpose.

description: Models for effort and cost estimation are important for distributed software development as well as for collocated software and system development. Standard cost models only insufficiently consider the characteristics of distributed development such as dissimilar abilities at the different sites or significant overhead due to remote collaboration. Therefore, explicit cost models for distributed development are needed. In this article, we present the initial development of a cost overhead model for a Spanish global software development organization. The model was developed using the CoBRA approach for cost estimation. As a result, cost drivers for the specific distributed development context were identified and their impact was quantified on an empirical basis. The article presents related work, an overview of the approach, and its application in the industrial context. Finally, we sketch the inclusion of the model in an approach for systematic task allocation and give an overview of future work.

A non-classical role for polycomb repressive complex 2 in co-ordinating adherens junctions and canonical Wnt signalling in embryonic stem cells and differentiation
Creators: name: Owen, Ceris Ifan
Publisher: name: Imperial College London
Year: 2020

description: Polycomb repressive complex 2 (PRC2) has a well characterised role in maintaining gene silencing and is essential for normal development, tissue homeostasis and is frequently dysregulated in cancer. The classical role of PRC2 is to catalyse post-translational modification of histone tails, with tri-methylation of Histone 3 lysine 27 strongly associated with gene silencing. Recent studies have highlighted additional non-classical roles for PRC2 including methylation of non-histone substrates, direct transcriptional activation and association with cell signalling cascades. Here I show that loss of core PRC2 components results in reduced Wnt signalling in embryonic stem cells (ESCs). Mouse ESCs that lack Suz12 show virtually undetectable canonical Wnt signalling. ESCs lacking Suz12 fail to differentiate. Intriguingly, efficient downregulation of pluripotency genes, but failure of induction of lineage specific genes is observed. In addition to the contribution to canonical Wnt signalling, beta-catenin also complexes with E-cadherin at cell surface adherens junctions. Importantly, altered E-cadherin localisation is observed in PRC2 null ES cells. E-cadherin localisation is normalised at cell-cell contacts between PRC2 mutant and wild type ES cells when grown together. Normalisation of E-cadherin localisation occurs concomitant to reestablishment of canonical Wnt signalling, and rescue of neuronal differentiation. The dual residency protein Afadin, a constituent of the intracellular adherens junction complex is also shown to have altered subcellular localisation in the absence of Jarid2 or Suz12. Taken together these results suggests a potential non-classical role for PRC2 in regulation of the adherens junctions, which in turn modifies the contribution of cadherin associated beta-catenin to Wnt signalling, and differentiation.

description: Current images of the supermassive black hole (SMBH) candidates at the center of our Galaxy and M87 have opened an unprecedented era for studying strong gravity and the nature of relativistic sources. Very-long-baseline interferometry (VLBI) data show images consistent with a central SMBH within General Relativity (GR). However, it is essential to consider whether other well-motivated dark compact objects within GR could produce similar images. Recent studies have shown that dark matter (DM) halos modeled as self-gravitating systems of neutral fermions can harbor very dense fermionic cores at their centers, which can mimic the spacetime features of a black hole (BH). Such dense, horizonless DM cores can satisfy the observational constraints: they can be supermassive and compact and lack a hard surface. We investigate whether such cores can produce similar observational signatures to those of BHs when illuminated by an accretion disk. We compute images and spectra of the fermion cores with a general-relativistic ray tracing technique, assuming the radiation originates from standard $α$ disks, which are self-consistently solved within the current DM framework. Our simulated images possess a central brightness depression surrounded by a ring-like feature, resembling what is expected in the BH scenario. For Milky Way-like halos, the central brightness depressions have diameters down to $\sim 35\, μ$as as measured from a distance of approximately $8\,$kpc. Finally, we show that the DM cores do not possess photon rings, a key difference from the BH paradigm, which could help discriminate between the models.

Automatic Reconfiguration of Untimed Discrete-Event Systems

description: This work introduces a general formulation of the reconfiguration problem for untimed discrete-event systems (DES), which can be treated directly by supervisory control theory (SCT). To model the reconfiguration requirements we introduce the concept of reconfiguration specification (RS); here reconfiguration events (RE) are introduced to force a transition from one system configuration to another. Standard SCT synthesis is employed to obtain a reconfiguration supervisor (RSUP) in which designated states serve as the source states for RE. The reconfiguration problem itself is formulated as that of establishing guaranteed finite reachability of a desired RE source state in RSUP from the current state in RSUP at which a change in configuration is commanded by an external user. The solvability (or otherwise) of this reachability problem is established by backtracking as in standard dynamic programming.

description: Phase transitions are a common phenomenon in condensed matter and act as a critical degree of freedom that can be employed to tailor the mechanical or electronic properties of materials. Understanding the fundamental mechanisms of the thermodynamics and kinetics of phase transitions is, thus, at the core of modern materials design. Conventionally, studies of phase transitions have, to a large extent, focused on pristine bulk phases. However, realistic materials exist in a complex form; their microstructures consist of different point and extended defects. The presence of defects impacts the thermodynamics and kinetics of phase transitions, but has been commonly ignored or treated separately. In recent years, with the significant advances in theoretical and experimental techniques, there has been an increasing research interest in modeling and characterizing how defects impact or even dictate phase transitions. The present review systematically discusses the recent progress in understanding the kinetics of defect-characterized phase transitions, derives the key mechanisms underlying these phase transitions, and envisions the remaining challenges and fruitful research directions. We hope that these discussions and insights will help to inspire future research and development in the field.

description: The median-voter hypothesis (MVH) predicts convergence of two party platforms across a one-dimensional political spectrum during majoritarian elections. From the viewpoint of the MVH, an explanation of polarization is that each election has a different median voter so that a party cannot please all the median voters at the same time. We consider two parties competing to win voters along a one-dimensional spectrum and assume that each party nominates one candidate out of two in the primary election, for which the electorates represent only one side of the whole population. We argue that all the four candidates will come to the same distance from the median of the total population through best-response dynamics.

description: In the context of topflavor seesaw model, we study the production of the heavy charged gauge boson ${W_{H}}$ associated with a top quark at the LHC. Focusing on the searching channel $pp\rightarrow tW_H\rightarrow t\bar{t}b \rightarrow lνjjbbb$, we carry out a full simulation of the signal and the relevant standard model backgrounds. The kinematical distributions of final states are presented. It is found that the backgrounds can be significantly suppressed by sets of kinematic cuts, and the signal of the heavy charged boson might be detected at the LHC with $\sqrt{s}=14$ TeV. With a integrated luminosity of $\LL= $ 100 $fb^{-1}$, a $8.3 σ$ signal significance can be achieved for $m_{W_H}=1.6$ TeV.
