Do altmetrics correlate with the quality of papers? A large-scale empirical study based on F1000Prime data

description: In this study, we address the question whether (and to what extent, respectively) altmetrics are related to the scientific quality of papers (as measured by peer assessments). Only a few studies have previously investigated the relationship between altmetrics and assessments by peers. In the first step, we analyse the underlying dimensions of measurement for traditional metrics (citation counts) and altmetrics - by using principal component analysis (PCA) and factor analysis (FA). In the second step, we test the relationship between the dimensions and quality of papers (as measured by the post-publication peer-review system of F1000Prime assessments) - using regression analysis. The results of the PCA and FA show that altmetrics operate along different dimensions, whereas Mendeley counts are related to citation counts, and tweets form a separate dimension. The results of the regression analysis indicate that citation-based metrics and readership counts are significantly more related to quality, than tweets. This result on the one hand questions the use of Twitter counts for research evaluation purposes and on the other hand indicates potential use of Mendeley reader counts.

description:

At length stripped of any free and independent voice by male writers, Haitian and African novelists shattered the taboos surrounding sex and a liberated sexual expression during the second half of the 20th century. By exploring sexuality and sensuality in their work, these writers courageously managed to break free from the outskirts of society and reshape the inferior identity unjustly attributed to them by the literary canons. As there is a gap in in-depth research on this subject, our study aims to explore the different ways in which female sexuality is constructed on paper. The novels by Calixthe Beyala, Frieda Ekotto, Ken Bugul, Margaret Papillon, Yanick Lahens and Kettly Mars will allow us to focus on three themes often recurring in the female universe: violence, madness and prostitution. Particularly, the research will take into consideration the enunciative and discursive modalities, as well as the stylistic techniques that enabled these authors to enhance a strong female subjectivity through their bodies.

description: Using 7.5-year spectroscopic monitoring data of a sample of 17 Palomar-Green QSOs (PG QSOs) (z=0.061-0.371), we obtain the optical spectral slope for each object at all epochs by a power-law fit to the spectra in continuum bands. All of these 17 PG QSOs exhibit obvious spectral slope variability. Most of the 17 objects show anti-correlation between the spectral slope and the rest-frame 5100$Å$ continuum flux while five of them exist strong anti-correlation (correlation coefficient R larger than 0.5). For the ensemble of these 17 PG QSOs, a strong anti-correlation between the average spectral slope and the average rest-frame 5100$Å$ luminosity is found while no correlation is found between the spectral slope and the Eddington ratio. A median anti-correlation between spectral slope changes and continuum flux variations is also found which indicates a hardening of the spectrum during bright phases. Accretion disk (jet) instability models with other mechanisms associated with changes in the accretion processes are promising.

description: Adenomatous polyposis coli (APC) is mutated in colon cancers. During normal development, APC proteins are essential negative regulators of Wnt signaling and have cytoskeletal functions. Many functions have been proposed for APC proteins, but these have often rested on dominant-negative or partial loss-of-function approaches. Thus, despite intense interest in APC, significant questions remain about its full range of cellular functions and about how mutations in the gene affect these. We isolated six new alleles of Drosophila APC2. Two resemble the truncation alleles found in human tumors and one is a protein null. We generated ovaries and embryos null for both APC2 and APC1, and assessed the consequences of total loss of APC function, allowing us to test several previous hypotheses. Surprisingly, although complete loss of APC1 and APC2 resulted in strong activation of Wingless signaling, it did not substantially alter cell viability, cadherin-based adhesion, spindle morphology, orientation or selection of division plane, as predicted from previous studies. We also tested the hypothesis that truncated APC proteins found in tumors are dominant negative. Two mutant proteins have dominant effects on cytoskeletal regulation, affecting Wnt-independent nuclear retention in syncytial embryos. However, they do not have dominant-negative effects on Wnt signaling.

description: There has been substantial interest in estimating the value of a graph parameter, i.e., of a real-valued function defined on the set of finite graphs, by querying a randomly sampled substructure whose size is independent of the size of the input. Graph parameters that may be successfully estimated in this way are said to be testable or estimable, and the sample complexity $q_z=q_z(ε)$ of an estimable parameter $z$ is the size of a random sample of a graph $G$ required to ensure that the value of $z(G)$ may be estimated within an error of $ε$ with probability at least 2/3. In this paper, for any fixed monotone graph property $\mathcal{P}=\mbox{Forb}(\mathcal{F})$, we study the sample complexity of estimating a bounded graph parameter $z_{\mathcal{P}}$ that, for an input graph $G$, counts the number of spanning subgraphs of $G$ that satisfy $\mathcal{P}$. To improve upon previous upper bounds on the sample complexity, we show that the vertex set of any graph that satisfies a monotone property $\mathcal{P}$ may be partitioned equitably into a constant number of classes in such a way that the cluster graph induced by the partition is not far from satisfying a natural weighted graph generalization of $\mathcal{P}$. Properties for which this holds are said to be recoverable, and the study of recoverable properties may be of independent interest.
Se débrouiller à Dakar : langue(s) et culture(s) urbaines dans la bande dessinée Goorgoorlou de T.T. Fons

description:

In his successful comics series Goorgoorlou, the Senegalese journalist and cartoonist T.T. Fons depicts the difficulties of the day-to-day life in Dakar through the tragicomic adventures of the hero Goor, a symbol of the Senegalese everyman struggling with debts, political unrest, social distress and cultural paradoxes. This article introduces the economic, political and cultural context before discussing the linguistic features and the Italian translation of the series. Through vibrant images and a shared urban language, T.T. Fons shapes a national conscience out of a satirical publication and offers the readers a window into the dynamic linguistic landscape of Dakar. Goor speaks to all those who feel abandoned and deceived by the government in a way that truly reflects the multi-faceted linguistic system of urban Senegal: a skilful and authentic blend of French, Wolof, humoristic distortions and local idioms. Because its linguistic configuration acts as a de facto legitimation of an emerging urban culture between the late 1980s and the early 2000s, providing a suitable translation of the comics series into Italian has proved to be a challenging endeavour.

description: We present XMM-Newton observations of three optically-selected z > 0.6 clusters from the ESO Distant Cluster Survey (EDisCS), comprising the first results of a planned X-ray survey of the full EDisCS high-redshift sample. The EDisCS clusters were identified in the Las Campanas Distant Cluster Survey as surface brightness fluctuations in the optical sky and their masses and galaxy populations are well described by extensive photometric and spectroscopic observations. We detect two of the three clusters in the X-ray and place a firm upper limit on diffuse emission in the third cluster field. We are able to constrain the X-ray luminosity and temperature of the detected clusters and estimate their masses. We find the X-ray properties of the detected EDisCS clusters are similar to those of X-ray-selected clusters of comparable mass and -- unlike other high-redshift, optically-selected clusters -- are consistent with the T - sigma and L_x - sigma relations determined from X-ray selected clusters at low redshift. The X-ray determined mass estimates are generally consistent with those derived from weak lensing and spectroscopic analyses. These preliminary results suggest that the novel method of optical selection used to construct the EDisCS catalog may, like selection by X-ray luminosity, be well-suited for identification of relaxed, high-redshift clusters whose intracluster medium is in place and stable by z ~ 0.8.

description: Routing is a widespread approach to transfer information from a source node to a destination node in many deployed wireless ad-hoc networks. Today's implemented routing algorithms seek to efficiently find the path/route with the largest Full-Duplex (FD) capacity, which is given by the minimum among the point-to-point link capacities in the path. Such an approach may be suboptimal if then the nodes in the selected path are operated in Half-Duplex (HD) mode. Recently, the capacity (up to a constant gap that only depends on the number of nodes in the path) of an HD line network i.e., a path) has been shown to be equal to half of the minimum of the harmonic means of the capacities of two consecutive links in the path. This paper asks the questions of whether it is possible to design a polynomial-time algorithm that efficiently finds the path with the largest HD capacity in a relay network. This problem of finding that path is shown to be NP-hard in general. However, if the number of cycles in the network is polynomial in the number of nodes, then a polynomial-time algorithm can indeed be designed.
Esclusioni etniche nei regolamenti cultuali greci: la norma di Paros (IG XII 5, 225)

description:

This study aims to examine a well-known inscription (IG XII.5, 225) dated to the mid-fifth century BC and found in Paroikia, near the acropolis of the ancient polis of Paros. It shows a typical formula of access limitation to local cults: according to most scholars, the cult in question is to be identified with the worship of Kore Astos (the Citizen), who is mentioned in the second line. The Dorians are excluded from this cult, as is shown by the expression (xenoi Dorie) appearing at the beginning of the text in a very relevant position. On the basis of a close comparison between this text and other epigraphs as well as literary documents containing proscriptions which prevent foreigners from participating in cults, it can be concluded that our text offers the only known example of such a limitation pertaining a specific ethnos. The reason for this rule established in Paros lies in the background of the Pentecontaetia, when political relations between Athens and its allies against the Dorians were bolstered not only politically, but also through cultual practices. Kore was a pivotal deity in strengthening the sense of sharing cultural traits in both Parioi and Athenians; perhaps it is for this reason that those people who did not belong to the Ionian ethnos (the Dorians first) were excluded from this cult.

description: Dark matter in the halos surrounding galaxy groups and clusters can annihilate to high-energy photons. Recent advancements in the construction of galaxy group catalogs provide many thousands of potential extragalactic targets for dark matter. In this paper, we outline a procedure to infer the dark matter signal associated with a given galaxy group. Applying this procedure to a catalog of sources, one can create a full-sky map of the brightest extragalactic dark matter targets in the nearby Universe ($z\lesssim 0.03$), supplementing sources of dark matter annihilation from within the Local Group. As with searches for dark matter in dwarf galaxies, these extragalactic targets can be stacked together to enhance the signals associated with dark matter. We validate this procedure on mock $\textit{Fermi}$ gamma-ray data sets using a galaxy catalog constructed from the $\texttt{DarkSky}$ $N$-body cosmological simulation and demonstrate that the limits are robust, at $\mathcal{O}(1)$ levels, to systematic uncertainties on halo mass and concentration. We also quantify other sources of systematic uncertainty arising from the analysis and modeling assumptions. Our results suggest that a stacking analysis using galaxy group catalogs provides a powerful opportunity to discover extragalactic dark matter and complements existing studies of Milky Way dwarf galaxies.

description: Genetic changes affecting gene expression contribute to phenotypic divergence; thus, understanding how regulatory networks controlling gene expression change over time is critical for understanding evolution. Prior studies of expression differences within and between species have identified properties of regulatory divergence, but technical and biological differences among these studies make it difficult to assess the generality of these properties or to understand how regulatory changes accumulate with divergence time. Here, we address these issues by comparing gene expression among strains and species of Drosophila with a range of divergence times and use F1 hybrids to examine inheritance patterns and disentangle cis- and trans-regulatory changes. We find that the fixation of compensatory changes has caused the regulation of gene expression to diverge more rapidly than gene expression itself. Specifically, we observed that the proportion of genes with evidence of cis-regulatory divergence has increased more rapidly with divergence time than the proportion of genes with evidence of expression differences. Surprisingly, the amount of expression divergence explained by cis-regulatory changes did not increase steadily with divergence time, as was previously proposed. Rather, one species (Drosophila sechellia) showed an excess of cis-regulatory divergence that we argue most likely resulted from positive selection in this lineage. Taken together, this work reveals not only the rate at which gene expression evolves, but also the molecular and evolutionary mechanisms responsible for this evolution.

Greek/Latin bilingual inscriptions of Rome provide us with the opportunity to study the interaction/overlapping and linguistic mixtures between Greek and Latin speakers in the multiethnic Roman population from different points of view. By studying such texts as a whole (heterogeneous for typology, production, destination, chronology) I was able to distinguish various expressions of bilingualism: translation, transliteration, code-switching, juxtaposition of the two languages, isolated Greek words in Latin contexts and vice versa. The relationship between Latin and Greek is detectable through both epigraphic and linguistic style (layout, hierarchy, lexicon, morphological and phonetic facets).

A Caribbean Reading of American Cultural Idealism
Creators: name: Morrison, Derrilyn E.

description:

In Middle Passages, Edward Kamau Brathwaite’s poetic discourse propels the reader through the landscape of a postmodern American society where the cultural achievements, despite the historical suffering of modern African American people, are regathered and offered through the poetic lens of re-memory as an American artifact of excelling cultural value. In this paper, Brathwaite’s poetic discourse joins that of Claudia Rankine, whose Don’t Let Me Be Lonely offers a contemporary poetic confrontation between the American media’s distillation of history and the poetic re-memory of those events, through the eyes of the Black community. The collections maintain strong political overtones in their historicizing of the suffering that African peoples have endured wherever they are in the black diaspora. Read together, they challenge the mythological depictions of mainstream America as a nation that embraces cultural difference, while upholding the need for continuing a discourse that contests mainstream representations of the status quo of the black American community.

Aim of this article is to explore some paths of meaning in the lyrics of the South African poet Ingrid de Kok. I will analyse her relationship with the history of her country in various collections and the difficult balance between collective and personal ethos, trying to highlight her linguistic search for ethical spaces not colonized by the widespread and still racially loaded ideologies of her country. One of the main features in de Kok’s poetry, I think, is her capacity to allow opposing realities to coexhist. My article will deal with the notion of juxtaposition the way it comes across in some of her poems, both from a linguistic point of view and in terms of its imagery.

We consistently account for the contributions coming from both the box and triangle diagrams that contribute to the dissociation processes. The cross section is dominated by the D* \bar D and D* \bar D* channels. When summing up the four channels we find a maximum total cross section of about 2.3 mb at sqrt(s) \approx 4.1 GeV. We compare our results to the results of other model calculations.

description:

Drawing on the work of Elizabeth Freeman (2010), this study offers a contribution to the literary debate over historical progress and irregular temporalities by proposing an analysis of Rehana Rossouw’s timely novel New Times (2017). The book, all centred around the themes of betrayal versus remembrance, tells the story of a young journalist trying to heal secret wounds in the year after South Africa’s first democratic elections. While her identity is continuously questioned because of her male nickname, mixed slave heritage and uncertain sexuality, Ali starts her new job for the aptly-titled The New Times by uncovering the new government’s first signs of corruption and blindness towards the AIDS plague. By investigating what is left of the colonial in the supposedly postcolonial era, Rossouw’s novel takes a brave stand in a literary tradition that has rarely dared to deconstruct the myth of Mandela and of Liberation Day itself, calling for a deeper understanding of the often fractured temporalities of political change.

description: MicroRNAs (miRNAs) are a class of small RNAs that silence gene expression. In animal cells, miRNAs bind to the 3' untranslated regions of specific mRNAs and inhibit their translation. Although some targets of a handful of miRNAs are known, the number and identities of mRNA targets in the genome are uncertain, as are the developmental functions of miRNA regulation. To identify the global range of miRNA-regulated genes during oocyte maturation of Drosophila, we compared the proteome from wild-type oocytes with the proteome from oocytes lacking the dicer-1 gene, which is essential for biogenesis of miRNAs. Most identified proteins appeared to be subject to translation inhibition. Their transcripts contained putative binding sites in the 3' untranslated region for a subset of miRNAs, based on computer modeling. The fraction of genes subject to direct and indirect repression by miRNAs during oocyte maturation appears to be small (4%), and the genes tend to share a common functional relationship in protein biogenesis and turnover. The preponderance of genes that control global protein abundance suggests this process is under tight control by miRNAs at the onset of fertilization.

description: We employ several unsupervised machine learning techniques, including autoencoders, random trees embedding, and t-distributed stochastic neighboring ensemble (t-SNE), to reduce the dimensionality of, and therefore classify, raw (auxiliary) spin configurations generated, through Monte Carlo simulations of small clusters, for the Ising and Fermi-Hubbard models at finite temperatures. Results from a convolutional autoencoder for the three-dimensional Ising model can be shown to produce the magnetization and the susceptibility as a function of temperature with a high degree of accuracy. Quantum fluctuations distort this picture and prevent us from making such connections between the output of the autoencoder and physical observables for the Hubbard model. However, we are able to define an indicator based on the output of the t-SNE algorithm that shows a near perfect agreement with the antiferromagnetic structure factor of the model in two and three spatial dimensions in the weak-coupling regime. t-SNE also predicts a transition to the canted antiferromagnetic phase for the three-dimensional model when a strong magnetic field is present. We show that these techniques cannot be expected to work away from half filling when the "sign problem" in quantum Monte Carlo simulations is present.

description: Synchrotron is considered the dominant emission mechanism in the production of gamma-ray burst photons in the prompt as well as in the afterglow phase. Polarization is a characteristic feature of synchrotron and its study can reveal a wealth of information on the properties of the magnetic field and of the energy distribution in gamma-ray burst jets. In this paper I will review the theory and observations of gamma-ray bursts polarization. While the theory is well established, observations have prove difficult to perform, due to the weakness of the signal. The discriminating power of polarization observations, however, cannot be overestimated.

description: Kinesins are microtubule-based motor proteins that transport cargo to specific locations within the cell. However, the mechanisms by which cargoes are directed to specific cellular locations have remained elusive. Here, we investigated the in vivo movement of the Schizosaccharomyces pombe kinesin Tea2 to establish how it is targeted to microtubule tips and cell ends. Tea2 is loaded onto microtubules in the middle of the cell, in close proximity to the nucleus, and then travels using its intrinsic motor activity primarily at the tips of polymerizing microtubules. The microtubule-associated protein Mal3, an EB1 homologue, is required for loading and/or processivity of Tea2 and this function can be substituted by human EB1. In addition, the cell-end marker Tea1 is required to anchor Tea2 to cell ends. Movement of Tea1 and the CLIP170 homologue Tip1 to cell ends is abolished in Tea2 rigor (ATPase) mutants. We propose that microtubule-based transport from the vicinity of the nucleus to cell ends can be precisely regulated, with Mal3 required for loading/processivity, Tea2 for movement and Tea1 for cell-end anchoring.

We study two `toy applications' from the world of Luttinger liquid physics: the survival of power laws in lowly-excited states as well as the spectral function of high-energy `block' excitations which feature several single-particle Fermi edges.

description: Tempo2 is a new software package for the analysis of pulsar pulse times of arrival. In this paper we describe in detail the timing model used by tempo2, and discuss limitations on the attainable precision. In addition to the intrinsic slow-down behaviour of the pulsar, tempo2 accounts for the effects of a binary orbital motion, the secular motion of the pulsar or binary system, interstellar, Solar system and ionospheric dispersion, observatory motion (including Earth rotation, precession, nutation, polar motion and orbital motion), tropospheric propagation delay, and gravitational time dilation due to binary companions and Solar system bodies. We believe the timing model is accurate in its description of predictable systematic timing effects to better than one nanosecond, except in the case of relativistic binary systems where further theoretical development is needed. The largest remaining sources of potential error are measurement error, interstellar scattering, Solar system ephemeris errors, atomic clock instability and gravitational waves.

description:

This article examines the dual themes of vodou and mysticism in the novel Les arbres musiciens (1957) by Jacques Stéphen Alexis (1922-1961). If Compère Général Soleil (1955), his first novel, barely touches the question, it is his second novel, Les arbres musiciens, that develops this aspect. This one testifies to an excellent knowledge of Haitian vodou and its origins. The article thus shows the relationship that Jacques Stéphen Alexis has in his poetics with ancient Egypt, in particular, and Africa in general.

description: A new fluorogenic cyanine dye was synthesized and found to have low fluorescence quantum yield in fluid solution and in the presence of double-stranded DNA but 80-fold enhanced fluorescence in viscous glycerol solution. An RNA aptamer selected for binding to the new dye exhibits K(d) = 87 nM and 60-fold fluorescence enhancement. The dye-aptamer pair is a fluoromodule that can be incorporated into fluorescent sensors and labels.
Generalized Weinberg's approach to the a0/f0 case

description: The problem of whether it is possible to distinguish composite from elementary particles is studied in the framework of Weinberg's approach. The possibility to extend this approach to the case of unstable particles in the presence of inelastic channels is considered. The interplay between the low-energy scattering data and the admixture of a bare state in the resonance is discussed, and the implications for the a0(980)/f0(980) case are outlined.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Resolution enhancement in in-line holography by numerical compensation of vibrations

description: Mechanical vibrations of components of the optical system is one of the sources of blurring of interference pattern in coherent imaging systems. The problem is especially important in holography where the resolution of the reconstructed objects depends on the effective size of the hologram, that is on the extent of the interference pattern, and on the contrast of the interference fringes. We discuss the mathematical relation between the vibrations, the hologram contrast and the reconstructed object. We show how vibrations can be post-filtered out from the hologram or from the reconstructed object assuming a Gaussian distribution of the vibrations. We also provide a numerical example of compensation for directional motion blur. We demonstrate our approach for light optical and electron holograms, acquired with both, plane- as well as spherical-waves. As a result of such hologram deblurring, the resolution of the reconstructed objects is enhanced by almost a factor of 2. We believe that our approach opens up a new venue of post-experimental resolution enhancement in in-line holography by adapting the rich database/catalogue of motion deblurring algorithms developed for photography and image restoration applications.
Do tau lepton branching fractions obey Benford's law?

description: According to Benford's law, the most significant digit in many datasets is not uniformly distributed, but obeys a well defined power law distribution with smaller digits appearing more often. Among one of the myriad particle physics datasets available, we find that the leading decimal digit for the $τ$ lepton branching fraction shows marginal disagreement with the logarithmic behavior expected from the Benford distribution. We quantify the deviation from Benford's law using a $χ^2$ function valid for binomial data, and obtain a $χ^2$ value of 16.9 for nine degrees of freedom, which gives a $p$-value of about 5%, corresponding to a 1.6$σ$ disagreement. We also checked that the disagreement persists under scaling the branching fractions, as well as by redoing the analysis in a numerical system with a base different from 10. Among all the digits, `9' shows the largest discrepancy with an excess of $4σ$. This discrepancy is because the digit `9' is repeated for three distinct groups of correlated modes, with each group having a frequency of two or three, leading to double-counting. If we count each group of correlated modes only once, the discrepancy for this digit also disappears and we get pristine agreement with Benford distribution.

Experimental statistics of veering triangulations

description: Certain fibered hyperbolic 3-manifolds admit a $\mathit{\text{layered veering triangulation}}$, which can be constructed algorithmically given the stable lamination of the monodromy. These triangulations were introduced by Agol in 2011, and have been further studied by several others in the years since. We obtain experimental results which shed light on the combinatorial structure of veering triangulations, and its relation to certain topological invariants of the underlying manifold.

description: My dad, Horace William (Bill) Palmer, talked quite a bit about the Arctic convoys, but only when I asked him. They were transporting food, fuel, and munitions to Russia in Murmansk and Arkhangelsk. He served on various ships, including HMS Forrester, and said they were all nervous and frightened about a German battleship which was based in the Norwegian fjord—that it would come out when a convoy was passing and bomb or fire shells at the convoy. This was the Tirpitz, a very powerful ship which could fire shells 17 miles, so the convoy wouldn't even see it. In reality, any ships that were sunk were sunk by torpedoes from German submarines. Convoy ships were vulnerable and were attacked as they passed Norway. Dad's Royal Navy records said that he joined as a volunteer in 1933, so he must have gone straight from Chatham into the Navy. I don't think he had another job before this. He could remember seeing the huge amount of ice in the water, and the ice gathering on the ship's structure as they got further north. Sailors had to bash the ice off; otherwise, the ship could become unstable. I've seen pictures of the ship covered in ice.The noise in the engine rooms of the warships damaged his hearing, and he was invalided out of the Navy by about 1947. He was awarded the medals during the 2000s.
