description: Lattice discretizations of continuous manifolds are common tools used in a variety of physical contexts. Conventional discrete approximations, however, cannot capture all aspects of the original manifold, notably its topology. In this paper we discuss an approximation scheme due to Sorkin which correctly reproduces important topological aspects of continuum physics. The approximating topological spaces are partially ordered sets (posets), the partial order encoding the topology. Now, the topology of a manifold $M$ can be reconstructed from the commutative C*-algebra $\cc(M)$ of continuous functions defined on it. In turn, this algebra is generated by continuous probability densities in ordinary quantum physics on $M$. The latter also serve to specify the domains of observables like the Hamiltonian. For a poset, the role of this algebra is assumed by a noncommutative C$^*$-algebra $\ca $. This fact makes any poset a genuine `noncommutative' (`quantum') space, in the sense that the algebra of its `continuous functions' is a noncommutative C$^*$-algebra. We therefore also have a remarkable connection between finite approximations to quantum physics and noncommutative geometries. We use this connection to develop various approximation methods for doing quantum physics using $\ca$.

description: Background: The CD4/CD8 ratio is an indicator of immunosenescence and a predictor of all-cause mortality in HIV-infected patients. The effects of different ART regimens on CD4/CD8 ratio recovery remain unclear. Methods: Clinical cohort study of ART-treated patients from the CFAR Network of Integrated Clinical Systems (CNICS). We included ART-naive adults with HIV infection who achieved undetectable HIV RNA during the first 48 weeks of treatment and had additional follow-up 48 weeks after virological suppression (VS). Primary endpoints included increase in CD4/CD8 ratio at both timepoints and secondary endpoints were CD4/CD8 ratio recovery at cut-offs of ≥0.5 or ≥1.0. Results: Of 3971 subjects who met the study criteria, 1876 started ART with an NNRTI, 1804 with a PI and 291 with an integrase strand transfer inhibitor (INSTI). After adjusting for age, sex, race, year of entry, risk group, HCV serostatus, baseline viral load and baseline CD4/CD8 ratio, subjects on an NNRTI showed a significantly greater CD4/CD8 ratio gain compared with those on a PI, either 48 weeks after ART initiation or after 48 weeks of HIV RNA VS. The greater CD4/CD8 ratio improvement in the NNRTI arm was driven by a higher decline in CD8 counts. The INSTI group showed increased rates of CD4/CD8 ratio normalization at the ≥1.0 cut-off compared with the PI group. Conclusions: NNRTI therapy was associated with a greater increase in the CD4/CD8 ratio compared with PIs. NNRTI- and INSTI-based first-line ART were associated with higher rates of CD4/CD8 ratio normalization at a cutoff of 1.0 than a PI-based regimen, which might have clinical implications.

description: Motivated by the entropy computations relevant to the evaluation of decrease in entropy in bit reset operations, the authors investigate the deficit in an entropic inequality involving two independent random variables, one continuous and the other discrete. In the case where the continuous random variable is Gaussian, we derive strong quantitative bounds on the deficit in the inequality. More explicitly it is shown that the decay of the deficit is sub-Gaussian with respect to the reciprocal of the standard deviation of the Gaussian variable. What is more, up to rational terms these results are shown to be sharp.

Για την εκπλήρωση των ερευνητικών στόχων και την απάντηση των ερευνητικών ερωτημάτων διεξήχθη ποιοτική έρευνα με τη χρήση ημιδομημένων συνεντεύξεων σε 14 άτομα που εργάζονται στο Πανεπιστήμιο Πειραιά (μέλη ΔΕΠ και άτομα του διοικητικού). Η ανάλυση έγινε με τη χρήση κωδίκων και συχνοτήτων. Ένα από τα βασικά συμπεράσματα της Διπλωματικής ήταν ότι τα ελληνικά πανεπιστήμια ακολούθησαν συγκεκριμένες θεσμικές μεταρρυθμίσεις για να ανταποκριθούν στις διαφοροποιημένες εκπαιδευτικές ανάγκες των σπουδαστών επιχειρώντας παράλληλα να παρέχουν ποιοτικές υπηρεσίες μάθησης. Επιπλέον, η Διπλωματική ανέδειξε ότι εν μέσω της πανδημίας η Ελλάδα ανταποκρίθηκε άμεσα στην αντιμετώπιση κομβικών εκπαιδευτικών ζητημάτων. Η πρωτογενής έρευνα ανέδειξε επίσης την ανάγκη εφαρμογής νέων εκπαιδευτικών προσεγγίσεων με την βοήθεια των νέων τεχνολογιών. Ωστόσο, οι συμμετέχοντες στην έρευνα θεωρούν ότι η τηλεεκπαίδευση είναι μια σημαντική ευκαιρία. Επίσης, η Διπλωματική ανέδειξε κάποια από τα βασικά προβλήματα της τριτοβάθμιας εκπαίδευσης στην Ελλάδα (π.χ. έλλειψη κατάρτισης από το προσωπικό, έλλειψη υποστήριξης από το κράτους, μη εξελιγμένα τεχνολογικά μέσα, δυσκολίες πρόσβασης και επικοινωνίας). Ενθαρρυντικό είναι το γεγονός ότι οι επιδόσεις των φοιτητών αυξήθηκαν. Ωστόσο, μειώθηκε η κοινωνικοποίηση τους αλλά και το ερευνητικό τους έργο. Αναφορικά με την αποτελεσματικότητα των ελληνικών εκπαιδευτικών μεταρρυθμίσεων σε θεσμικό πλαίσιο, η Διπλωματική ανέδειξε ότι οι μεταρρυθμίσεις αυτές δεν διευκόλυναν την εκπαιδευτική διαδικασία.

description: In this paper we explore some general aspects of the embeddings associated with brane-localized gravity. In particular we show that the consistency of such embeddings can require (or impose) very specific relations between all the involved bulk and brane matter source parameters. We specifically explore the embeddings of 3-branes with non-zero spatial 3-curvature $k$ into 5-dimensional spacetime bulks, and show that for such embeddings, a 5-dimensional bulk cosmological constant is not able to produce the exponential suppression of the geometry thought necessary to localize gravity to the brane.

description: Lyman alpha emission presents a means of identifying very high redshift galaxies, provided such objects can be reliably distinguished from foreground emission-line galaxies. Here we report on a program of imaging and spectroscopic studies being conducted with the Keck telescope, in concert with additional efforts from the ground and with HST, to study such high-redshift objects over the range from z=3 to 7. The first deep narrow-band imaging studies with Keck are used to show that strong Lyman alpha emitters, such as have been seen in high-redshift quasar fields at z>4.5, can be found in the field populations. Based on studies of the HDF and the Hawaii Survey Fields these are significant contributors to the star formation rates at these epochs.

description: Background: Studies suggest lower risk of breast cancer in women with HIV versus without HIV. These estimates may be biased by lower life expectancy and younger age distribution of women with HIV. Our analysis evaluated this bias and characterized secular trends in breast cancer among women with HIV initiating antiretroviral therapy. We hypothesized breast cancer risk would increase over time as mortality decreased. Setting: Women with HIV prescribed antiretroviral therapy in the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) from 1997 through 2016. Methods: We estimated breast cancer hazard (cause-specific hazard ratios) and cumulative incidence accounting for competing risks (subdistribution hazard ratios) to assess changes in breast cancer risk over time. This was assessed overall (1997-2016) and within/across calendar periods. Analyses were adjusted for race/ethnicity and inverse probability weighted for cohort. Cumulative incidence was graphically assessed by calendar period and race/ethnicity. Results: We observed 11,587 women during 1997-2016, contributing 63 incident breast cancer diagnoses and 1,353 deaths [73,445 person-years (median followup = 4.5 years)]. Breast cancer cumulative incidence was 3.2% for 1997-2016. We observed no secular trends in breast cancer hazard or cumulative incidence. There were annual declines in the hazard and cumulative incidence of death (cause-specific hazard ratios and subdistribution hazard ratios: 0.89, 95% confidence interval: 0.87 to 0.91) which remained within and across calendar periods. Conclusions: These findings contradict the hypothesis of increasing breast cancer risk with declining mortality over time among women with HIV, suggesting limited impact of changing mortality on breast cancer risk. Additional inquiry is merited as survival improves among women with HIV.
Targeting G-quadruplex DNA in promoters of cardiac function-related genes
Creators: name: Zhou, Wenhua
Publisher: name: Imperial College London
Year: 2012

description: G-quadruplexes (G4) are four-stranded DNA secondary structures, which are involved in a diverse range of biological processes. Although the anti-cancer potential of G4s in promoters of oncogenes has been thoroughly investigated, the functions of promoter G4s in non-cancer-related genes are not well understood. The aims of this thesis are (i) to investigate the biological importance of promoter G4s in cardiac function-related genes, and (ii) to explore the feasibility and potential of multitargeting strategy at the single gene level. These aims have been achieved by revealing the prevalence of G4s in TRRs (transcription regulatory regions) of cardiac function-related genes via bioinformatics approaches, and then investigating potential biological significance of G4s in promoters of human MEF2D and TnIc genes via a combination of biophysical, molecular, and cell biology approaches. By using bioinformatics approaches, TRRs of cardiac function-related genes were found to be enriched by potential G4-forming sequences. According to these results, G4s from the promoters of human MEF2D and TnIc were chosen and subjected to biophysical characterisations in solution. By using EMSA, DMS footprinting, CD and smFRET spectroscopy, the formation, thermodynamic stability, and unfolding kinetics of MEF2D and TnIc G4s were investigated. Briefly, in 100 mM K+, the MEF2DG4 can adopt a hybrid of very stable parallel/anti-parallel G4(s), while the TnIc MNSG4 and -80G4 are able to adopt anti-parallel and parallel structures, respectively, with comparable stability as compared to other oncogene G4s. Subsequently, cooperative regulatory roles of TnIc G4s as enhancers once stabilised by a G4-binding ligand (di-copper complex) were observed in vitro mainly by dual luciferase reporter assays in HEK293 cells. Three possible G4-mediated mechanisms have been proposed. This work provides the first indication about the biological significance of promoter G4s in cardiac function-related genes, and the feasibility to target multiple G4s at the single gene level.

description: Optically pumped magnetometers are becoming a promising alternative to cryogenically-cooled superconducting magnetometers for detecting and imaging biomagnetic fields. Magnetic field detection is a completely non-invasive method, which allows one to study the function of excitable human organs with a sensor placed outside the human body. For instance, magnetometers can be used to detect brain activity or to study the activity of the heart. We have developed a highly sensitive miniature optically pumped magnetometer based on cesium atomic vapor kept in a paraffin-coated glass container. The magnetometer is optimized for detection of biological signals and has high temporal and spatial resolution. It is operated at room- or human body temperature and can be placed in contact with or at a mm-distance from a biological object. With this magnetometer, we detected the heartbeat of an isolated guinea-pig heart, which is an animal widely used in biomedical studies. In our recordings of the magnetocardiogram, we can in real-time observe the P-wave, QRS-complex and T-wave associated with the cardiac cycle. We also demonstrate that our device is capable of measuring the cardiac electrographic intervals, such as the RR- and QT-interval, and detecting drug-induced prolongation of the QT-interval, which is important for medical diagnostics.

description: Temperate forests are characterised by variable light quality (i.e. spectral composition of light) at or near the forest floor. These understory environments have a high concentration of green light, as red and blue light are preferentially absorbed by upper canopy leaves. Understory species may be well-adapted for using green light to drive photosynthesis. Angiosperms have been shown to use green light for photosynthesis, but this ability has not been demonstrated in shade-dwelling bryophytes. In this study, net photosynthetic rate (PN) of three temperate understory species of moss (Dichodontium pellucidum (Hedw.) Schimp., Leucobryum albidum (Brid. ex P.Beauv) Lindb. and Amblystegium serpens (Hedw.) Schimp.) was measured under green, red + blue, and red + blue + green light to assess green light use efficiency. All three species were capable of photosynthesising beyond their respiratory demands using solely green light, with higher green light use efficiency measured in plants collected from areas with greater canopy cover, suggesting growth in a green light concentrated environment increases green light use efficiency. Each species was also collected from sites differing in their degree of canopy cover and grown under three light treatments (high light, low light, and green light). Photosynthetic efficiency (chlorophyll fluorescence), tissue nitrogen and carbon isotope concentrations were assessed after a short growth period. Growth conditions had little effect on leaf chemistry and monochromatic green light did not significantly degrade photosynthetic efficiency. This study provides the first evidence to date of positive net ‘green light photosynthesis’ in mosses.

description: Comparison among graphs is ubiquitous in graph analytics. However, it is a hard task in terms of the expressiveness of the employed similarity measure and the efficiency of its computation. Ideally, graph comparison should be invariant to the order of nodes and the sizes of compared graphs, adaptive to the scale of graph patterns, and scalable. Unfortunately, these properties have not been addressed together. Graph comparisons still rely on direct approaches, graph kernels, or representation-based methods, which are all inefficient and impractical for large graph collections. In this paper, we propose the Network Laplacian Spectral Descriptor (NetLSD): the first, to our knowledge, permutation- and size-invariant, scale-adaptive, and efficiently computable graph representation method that allows for straightforward comparisons of large graphs. NetLSD extracts a compact signature that inherits the formal properties of the Laplacian spectrum, specifically its heat or wave kernel; thus, it hears the shape of a graph. Our evaluation on a variety of real-world graphs demonstrates that it outperforms previous works in both expressiveness and efficiency.

description: Background: Age-related macular degeneration is a progressive eye disease affecting the macula and causing acute visual loss particularly in elder people. The aim of the study was an attempt to discern an influence of expression levels and functional genetic polymorphisms of selected genes related to the extracellular matrix turnover or neovascularization on age-related macular degeneration occurrence and progression. Methods: We conducted a case-control study of 200 polish patients with recognized age-related macular degeneration (dry and wet) and compared the results with those obtained from matched 100 healthy control subjects. TaqMan Genotyping Assays were employed to examine the following single nucleotide polymorphisms: matrix metalloproteinase (MMP)-2 −735C/T, MMP-7 −181A/G, MMP-9 −1702T/A, and −1562C/T; tissue inhibitors of metalloproteinase (TIMP)-2 −418G/C; vascular endothelial growth factor (VEGF) +405 G/C and +936 C/T, VEGFR-2 +1719 T/A and −271 G/A. Real-time polymerase chain reaction was assessed to determine the mRNA quantity. Serum levels of proteins were measured using enzyme-linked immunosorbent assay. Results: The single nucleotide polymorphism genotyping showed that TT genotype for MMP-9 −1702T/A and CC genotype for VEGF +936C/T increase markedly the risk of age-related macular degeneration but do not influence on its progression. Additionally, the possible protective effect of CC genetic variant in MMP-9 −1562C/T polymorphism against progression of age-related macular degeneration was observed. We also found significant differences in systemic expression levels of MMP-2, -7, -9, TIMP-2, vascular endothelial growth factor, VEGFR-2, and pigment epithelium-derived factor between studied group. The research demonstrated evident differences in serum levels of MMP-2, -7, -9, TIMP-2, vascular endothelial growth factor, and pigment epithelium-derived factor between wet and dry age-related macular degeneration patients. Conclusions: We can conclude that disturbances in angiogenic homeostasis and processes of extracellular matrix turnover occurring in age-related macular degeneration-affected ocular tissues may be reflected in changes in systemic expression levels of the investigated genes.

description: Background: Most studies of stroke in people living with HIV (PLWH) do not use verified stroke diagnoses, are small, and/or do not differentiate stroke types and subtypes.Setting: CNICS, a U.S. multisite clinical cohort of PLWH in care.Methods: We implemented a centralized adjudication stroke protocol to identify stroke type, subtype, and precipitating conditions identified as direct causes including infection and illicit drug use in a large diverse HIV cohort.Results: Among 26,514 PLWH, there were 401 strokes, 75% of which were ischemic. Precipitating factors such as sepsis or same-day cocaine use were identified in 40% of ischemic strokes. Those with precipitating factors were younger, had more severe HIV disease, and fewer traditional stroke risk factors such as diabetes and hypertension. Ischemic stroke subtypes included cardioembolic (20%), large vessel atherosclerosis (13%), and small vessel (24%) ischemic strokes. Individuals with small vessel strokes were older, were more likely to have a higher current CD4 cell count than those with cardioembolic strokes and had the highest mean blood pressure of the ischemic stroke subtypes.Conclusion: Ischemic stroke, particularly small vessel and cardioembolic subtypes, were the most common strokes among PLWH. Traditional and HIV-related risk factors differed by stroke type/subtype. Precipitating factors including infections and drug use were common. These results suggest that there may be different biological phenomena occurring among PLWH and that understanding HIV-related and traditional risk factors and in particular precipitating factors for each type/subtype may be key to understanding, and therefore preventing, strokes among PLWH.

description: BINOL derived chiral phosphoric acids (CPAs) are widely known for their high selectivity. Numerous 3,3’ substituents are used for a variety of stereoselective reactions and theoretical models of their effects are provided. However, experimental data about the structural space of CPA complexes in solution is extremely rare and so far restricted to NMR investigations of binary TRIP/imine complexes featuring two E- and two Z-imine conformations. Therefore, in this paper the structural space of 16 CPA/imine binary complexes is screened and 8 of them are investigated in detail by NMR. For the first time dimers of CPA/imine complexes in solution were experimentally identified, which show an imine position similar to the transition state in transfer hydrogenations. Furthermore, our experimental and computational data revealed an astonishing invariance of the four core structures regardless of the different steric and electronic properties of the 3,3’-substituent. However, a significant variation of E/Z-ratios is observed, demonstrating a strong influence of the 3,3’-substituents on the stabilization of the imine in the complexes. These experimental E/Z-ratios cannot be reproduced by calculations commonly applied for mechanistic studies, despite extensive conformational scans and treatment of the electronic structure at a high level of theory with various implicit solvent corrections. Thus, this first detailed experimental data about the structural space and influence of the 3,3’ substituent on the energetics of CPA/imine complexes can serve as basis to validate and improve theoretical predictive models.

description: We present new $n=(1,1)$ and $n=(1,0)$ supersymmetric generalization of the Liouville equation, which originate from a geometrical approach to describing the classical dynamics of Green--Schwarz superstrings in $N=2,~D=3$ and $N=1,~D=3$ target superspace. Considered are a zero curvature representation and Bäcklund transformations associated with the supersymmetric non--linear equations.

description: Background: We investigated the prospective association between a brief self-report measure of engagement in human immunodeficiency virus (HIV) care (the Index of Engagement in HIV Care; hereafter "Index") and suboptimal retention and viral suppression outcomes. Methods: The Centers for AIDS Research Network of Integrated Clinical Systems cohort study combines medical record data with patient-reported outcomes from 8 HIV clinics in the United States, which from April 2016 to March 2017 included the 10-item Index. Multivariable logistic regression was used to estimate the risk and odds ratios of mean Index scores on 2 outcomes in the subsequent year: (1) not keeping ≥75% of scheduled HIV care appointments; and (2) for those with viral suppression at Index assessment, having viral load >200 copies/mL on ≥1 measurement. We also used generalized linear mixed models (GLMMs) to estimate the risk and odds ratios of appointment nonattendance or unsuppressed viral load at any given observation. We generated receiver operating characteristic curves for the full models overlaid with the Index as a sole predictor. Results: The mean Index score was 4.5 (standard deviation, 0.6). Higher Index scores were associated with lower relative risk of suboptimal retention (n = 2576; logistic regression adjusted risk ratio [aRR], 0.88 [95% confidence interval,. 87-.88]; GLMM aRR, 0.85 [.83-.87]) and lack of sustained viral suppression (n = 2499; logistic regression aRR, 0.75 [.68-.83]; GLMM aRR, 0.74 [.68-.80]). The areas under the receiver operating characteristic curve for the full models were 0.69 (95% confidence interval,. 67-.71) for suboptimal retention and 0.76 (.72-.79) for lack of sustained viral suppression. Conclusions: Index scores are significantly associated with suboptimal retention and viral suppression outcomes.

description: Unraveling ultrafast dynamical processes in highly excited molecular species has an impact on our understanding of chemical processes such as combustion or the chemical composition of molecular clouds in the universe. In this article we use short (<7 fs) XUV pulses to produce excited cationic states of benzene molecules and probe their dynamics using few-cycle VIS/NIR laser pulses. The excited states produced by the XUV pulses lie in an especially complex spectral region where multi-electronic effects play a dominant role. We show that very fast τ ≈ 20 fs nonadiabatic processes dominate the relaxation of these states, in agreement with the timescale expected for most excited cationic states in benzene. In the CH3+ fragmentation channel of the doubly ionized benzene cation we identify pathways that involve structural rearrangement and proton migration to a specific carbon atom. Further, we observe non-trivial transient behavior in this fragment channel, which can be interpreted either in terms of propagation of the nuclear wavepacket in the initially excited electronic state of the cation or as a two-step electronic relaxation via an intermediate state.

description: We report the detection of two exoplanets and a further tentative candidate around the M-dwarf stars Gl96 and Gl617A, based on radial velocity measurements obtained with the SOPHIE spectrograph at the Observatoire de Haute-Provence. Both stars were observed in the context of the SOPHIE exoplanet consortium's dedicated M-dwarf subprogramme, which aims to detect exoplanets around nearby M-dwarf stars through a systematic survey. For Gl96, we present the discovery of a new exoplanet at 73.9 d with a minimum mass of 19.66 earth masses. Gl96 b has an eccentricity of 0.44, placing it among the most eccentric planets orbiting M stars. For Gl617A we independently confirm a recently reported exoplanet at 86.7 d with a minimum mass of 31.29 earth masses. Both Gl96 b and Gl617A b are potentially within the habitable zone, though Gl96 b's high eccentricity may take it too close to the star at periapsis.

description: "Life Science Database Cross Search" is a knowledge infrastructure for life science researchers. This service was originally developed in Database Center for Life Science (DBCLS), and was transferred to National Bioscience Database Center (NBDC) in 2011. It provides a web search service across more than 670 public databases (containing 15 million entries). This open infrastructure supports the research data to be "FAIR". For instance, on the point of principle F2 (provided rich meta data) and F3 (indexed in searchable resource), which are difficult to achieve by each data provider or general search engine, our search system can fulfill the terms. Our infrastructure also accelerates the utilization of semantically integrated life science data.

description: Background: Among people living with HIV (PLWH), physical intimate partner violence (IPV) is associated with poor virologic, psychiatric, and behavioral outcomes. We examined non-physical, psychological intimate partner violence (psy-IPV) and HIV care outcomes using data from two U.S. consortia. Methods: We conducted multivariable analyses with robust standard errors to compare patients indicating/not indicating psy-IPV. Results: Among PLWH (n = 5950), 9.5% indicated psy-IPV; these individuals were younger (− 3; 95% CI [− 2,-4], p-value < 0.001), less likely to be on antiretroviral treatment (ART) (0.73 [0.55,0.97], p = 0.03), less adherent to ART (− 4.2 [− 5.9,-2.4], p < 0.001), had higher odds of detectable viral load (1.43 [1.15,1.78], p = 0.001) and depression (2.63 [2.18,3.18], p < 0.001), and greater use of methamphetamines/crystal [2.98 (2.30,3.87),p < 0.001], cocaine/crack [1.57 (1.24,1.99),p < 0.001], illicit opioids [1.56 (1.13,2.16),p = 0.007], and marijuana [1.40 (1.15,1.70), p < 0.001]. Conclusion: Psychological IPV, even in the absence of physical or sexual IPV, appears to be associated with HIV care outcomes and should be included in IPV measures integrated into routine HIV care.

description: Depuis 2005, le Service d’archéologie préventive d’Eure-et-Loir a pris en charge près de 40 % des diagnostics prescrits sur le département. De la préparation des opérations à la diffusion des résultats, l’équipe d’archéologues place le diagnostic au cœur d’une démarche scientifique globale. Le séminaire de Caen était donc l’occasion de partager ces 13 années d’expérience et de pratique du diagnostic en collectivité territoriale. Après avoir brièvement exposé le cadre de cette pratique, l’accent est mis sur trois principaux axes de travail issus de la recherche conduite lors des diagnostics : la connaissance des contextes chrono-stratigraphiques à l’échelle du département, la modélisation de l’occupation des territoires, l’utilisation des données isolées dans des réflexions multiscalaires.

From the preparation of operations to the dissemination of results, the team of archaeologists places this kind of operation at the heart of a global scientific approach. The Caen seminar was therefore an opportunity to share these 13 years of experience and practice of evaluations in territorial authorities. After a brief presentation of the framework of this practice, the emphasis was placed on three main lines of work resulting from the research conducted during the diagnoses: knowledge of chrono-stratigraphic contexts on the scale of the department, modeling of the occupation of territories, and the use of isolated data in multiscalar reflections.
