description: We report the discovery of a low-mass companion to the nearby (d = 47 pc) F7V star HD 984. The companion is detected 0.19" away from its host star in the L' band with the Apodizing Phase Plate on NaCo/VLT and was recovered by L'-band non-coronagraphic imaging data taken a few days later. We confirm the companion is co-moving with the star with SINFONI integral field spectrograph H+K data. We present the first published data obtained with SINFONI in pupil-tracking mode. HD 984 has been argued to be a kinematic member of the 30 Myr-old Columba group, and its HR diagram position is not altogether inconsistent with being a ZAMS star of this age. By consolidating different age indicators, including isochronal age, coronal X-ray emission, and stellar rotation, we independently estimate a main sequence age of 115$\pm$85 Myr (95% CL) which does not rely on this kinematic association. The mass of directly imaged companions are usually inferred from theoretical evolutionary tracks, which are highly dependent on the age of the star. Based on the age extrema, we demonstrate that with our photometric data alone, the companion's mass is highly uncertain: between 33 and 96 M$_{\rm Jup}$ (0.03-0.09 M$_{\odot}$) using the COND evolutionary models. We compare the companion's SINFONI spectrum with field dwarf spectra to break this degeneracy. Based on the slope and shape of the spectrum in the H-band, we conclude that the companion is an M$6.0\pm0.5$ dwarf. The age of the system is not further constrained by the companion, as M dwarfs are poorly fit on low-mass evolutionary tracks. This discovery emphasizes the importance of obtaining a spectrum to spectral type companions around F-stars.

description: BackgroundIn Zambia the vast majority of chest radiographs (CXR) are read by clinical officers who have limited training and varied interpretation experience, meaning lower inter-rater reliability and limiting the usefulness of CXR as a diagnostic tool. In 2010–11, the Zambian Prison Service and Ministry of Health established TB and HIV screening programs in six prisons; screening included digital radiography for all participants. Using front-line clinicians we evaluated sensitivity, specificity and inter-rater agreement for digital CXR interpretation using the Chest Radiograph Reading and Recording System (CRRS).MethodsDigital radiographs were selected from HIV-infected and uninfected inmates who participated in a TB and HIV screening program at two Zambian prisons. Two medical officers (MOs) and two clinical officers (COs) independently interpreted all CXRs. We calculated sensitivity and specificity of CXR interpretations compared to culture as the gold standard and evaluated inter-rater reliability using percent agreement and kappa coefficients.Results571 CXRs were included in analyses. Sensitivity of the interpretation “any abnormality” ranged from 50–70% depending on the reader and the patients’ HIV status. In general, MO’s had higher specificities than COs. Kappa coefficients for the ratings of “abnormalities consistent with TB” and “any abnormality” showed good agreement between MOs on HIV-uninfected CXRs and moderate agreement on HIV-infected CXRs whereas the COs demonstrated fair agreement in both categories, regardless of HIV status.ConclusionsSensitivity, specificity and inter-rater agreement varied substantially between readers with different experience and training, however the medical officers who underwent formal CRRS training had more consistent interpretations.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-016-1460-z) contains supplementary material, which is available to authorized users.

description: В работе осуществлен аналитический обзор результатов прямого геохимического опробования и данных водорастворенных газов, полученных при глубоком бурении. По результатам сопоставления составов газов подтверждается наличие как минимум двух различных типов газов. При этом газ, характеризующийся как глубинный, имеет четкие черты схожие с газами разрушающихся нефтяных скоплений. Сделано предположение, что близповерхностные газы, обогащенные азотом и углекислым газом, могут быть связаны с углистыми отложениями верхней юры и нижнего мела. Рекомендовано проведение площадных геохимических опробований с использованием искусственных сорбентов по ароматическим углеводородам. Отмечена необходимость выделения в разрезе мезозойско-кайнозойских отложений потенциальных ловушек пластов-коллекторов и перекрывающих их флюидоупоров для опоискования в них залежей нефти и газа.

description: В статье приводится аналитический обзор результатов прямых геохимических исследований Вилюйской синеклизы одной из перспективных на нефть и газ территорий востока Сибирской платформы. Показано, что над всеми продуктивными структурами получены профильные контрастные аномалии. При этом установлено общее нарастание легких углеводородных (УВ) компонентов от флангов к ее центру и приуроченность наиболее ощутимых микроконцентраций тяжелых углеводородов (ТУ) к периклинальным участкам продуктивных структур. Также отмечается пятнистый характер профильных аномалий над продуктивными структурами. Приведены результаты работ, проведенных в 2016 году на южной периклинали Средневилюйского газоконденсатного месторождения. Зафиксированы относительно высокие значения бензола и толуола над зонами распространения залежей T1-Па и T1 -III. Сделано предположение, что максимальные значения Б/Т могут быть приурочены к зонам нефтяных скоплений. Сделан вывод, что в комплексе с другими геолого-геофизическими методами прямые геохимические исследования позволят увеличить достоверность прогноза перспектив нефтегазоносности слабоизученных территорий.

Целью работы было выявление информативных геохимических параметров для дифференцирования природного фона и поверхностных естественных проявлений нефти (высачивание) от техногенных углеводородных полей, сформировавшихся при разливах нефти и нефтепродуктов. Методами битуминологии, ИК-Фурье и газовой хромато-масс-спектрометрии было выполнено сравнительное изучение состава битумоидов органического вещества проб современных осадков (почв), естественных нефтепроявлений и нефтезагрязнений техногенного генезиса. Показано, что генетическими параметрами при диагностике загрязнения почв нефтью и нефтепродуктами могут служить углеводороды-биомаркеры и характерные особенности химической структуры и группового компонентного состава битумоидов.

description: A new computational method for finite-temperature properties of strongly correlated electrons is proposed by extending the variational Monte Carlo method originally developed for the ground state. The method is based on the path integral in the imaginary-time formulation, starting from the infinite-temperature state that is well approximated by a small number of certain random initial states. Lower temperatures are progressively reached by the imaginary-time evolution. The algorithm follows the framework of the quantum transfer matrix and finite-temperature Lanczos methods, but we extends them to treat much larger system sizes without the negative sign problem by optimizing the truncated Hilbert space on the basis of the time-dependent variational principle (TDVP). This optimization algorithm is equivalent to the stochastic reconfiguration (SR) method that has been frequently used for the ground state to optimally truncate the Hilbert space. The obtained finite-temperature states allow an interpretation based on the thermal pure quantum (TPQ) state instead of the conventional canonical-ensemble average. Our method is tested for the one- and two-dimensional Hubbard models and its accuracy and efficiency are demonstrated.

description: Abstract Background Linkage to HIV care is crucial to the success of antiretroviral therapy (ART) programs worldwide, loss to follow up at all stages of the care continuum is frequent, and long-term prospective studies of care linkage are currently lacking. Methods Consecutive clients who tested HIV-positive were enrolled from four HIV testing centers (1 health facility and 3 community-based centers) in the Kilimanjaro region of Tanzania as part of the larger Coping with HIV/AIDS in Tanzania (CHAT) prospective observational study. Biannual interviews were conducted over 3.5 years, assessing care linkage, retention, and mental health. Bivariable and multivariate logistic regression analyses were conducted to determine associations with early death (prior to the second follow up interview) and delayed (>6 months post-test) or failed care linkage. Results A total of 263 participants were enrolled between November, 2008 and August, 2009 and 240 participants not already linked to care were retained in the final dataset. By 6 months after enrollment, 169 (70.4 %) of 240 participants had presented to an HIV care and treatment facility; 41 (17.1 %) delayed more than 6 months, 15 (6.3 %) died, and 15 (6.3 %) were lost to follow up. Twenty-six patients died before their second follow up visit and were analyzed in the early death group (10.8 %). Just 15 (9.6 %) of those linked to care had started ART within 6 months, but 123 (89.1 %) of patients documented to be ART eligible by local guidelines had started ART by the end of 3.5 years. On multivariate analysis, male gender (OR 1.72; 95 % CI 1.08, 2.75), testing due to illness (OR 1.63; 95 % CI 1.01, 2.63), and higher mean depression scale scores (4 % increased risk per increase in depression score; 95 % CI 1 %, 8 %) were associated with early death. Testing at a community versus a hospital-based site (OR 2.89; 95 % CI 1.79, 4.66) was strongly associated with delaying or never entering care. Conclusions Nearly 30 % of the cohort did not have timely care linkage, ART initiation was frequently delayed, and testing at a hospital outpatient department versus community-based testing centers was strongly associated with successful care linkage.

description: BACKGROUND: Malawi's national antiretroviral therapy program provides atazanavir/ritonavir-based second line regimens which cause concentration-dependent rise in indirect bilirubin. We sought to determine if elevated bilirubin, as a surrogate of atazanavir/ritonavir adherence, can aid in the evaluation of second line virological failure in Malawi.

METHODS: We conducted a cross-sectional study of HIV-infected patients ≥15 years who were on boosted protease inhibitor-based second line antiretroviral therapy for at least 6 months in two urban HIV clinics in Lilongwe, Malawi. Antiretroviral therapy history and adherence data were extracted from the electronic medical records and blood was drawn for viral load, complete blood count, total bilirubin, and CD4 cell count at a clinic visit. Factors associated with virological failure were assessed using multivariate logistic regression model.

RESULTS: Out of 376 patients on second line antiretroviral therapy evaluated, 372 (98.9%) were on atazanavir/ritonavir-based therapy and 142 (37.8%) were male. Mean age was 40.9 years (SD ± 10.1), mean duration on second line antiretroviral therapy was 41.9 months (SD ± 27.6) and 256 patients (68.1%) had elevated bilirubin >1.3 mg/dL. Overall, 35 (9.3%) patients had viral load >1000 copies/ml (virological failure). Among the virologically failing vs. non-failing patients, bilirubin was elevated in 34.3% vs. 72.0% respectively (p < 0.001), although adherence by pill count was similar (62.9% vs. 60.7%, p = 0.804). The odds of virological failure were higher for adults aged 25-40 years (adjusted odds ratio (aOR) 2.5, p = 0.048), those with CD4 cell count <100 (aOR 17.5, p < 0.001), and those with normal bilirubin levels (aOR 5.4, p < 0.001); but were lower for the overweight/obese patients (aOR 0.3, p = 0.026). Poor pill count adherence (aOR 0.7, p = 0.4) and male gender (aOR 1.2, p = 0.698) were not associated with second line virological failure.

CONCLUSIONS: Among patients receiving atazanavir/ritonavir-based second line antiretroviral therapy, bilirubin levels better predicted virological failure than pill count adherence. Therefore, strategic use of bilirubin and viral load testing to target adherence counseling and support may be cost-effective in monitoring second line antiretroviral therapy adherence and virological failure. Drug resistance testing targeted for patients with virological failure despite elevated bilirubin levels would facilitate timely switch to third line antiretroviral regimens whenever available.

description: Водные растворы солей влияют на равновесные условия и кинетические параметры гидратообразования природного газа в засоленных пористых средах. С увеличением концентрации растворов понижается температура гидратообразования газов за счет снижения активности воды, однако смещение равновесных условий может также зависеть от ионного состава электролита, который влияет на структуру воды. Одним из методов выявления изменения структуры воды является определение вязкости растворов. В работе изучена зависимость вязкости растворов хлоридов натрия и кальция, гидрокарбоната натрия методом Стокса и получены значения констант Вη уравнения Джонса-Доула. Установлено, что катионы натрия, кальция и гидрокарбонат-анион относятся к структурообразующим, а анион хлора к структуроразрушающим.

Creators: name: Kronfuss, Clara Anna-Maria
Year: 2023

description: Hintergrund: Schnelle und effektive Regenerationsmethoden rücken durch die großen Wettkampf- bzw. Trainingsbelastungen im Sport immer mehr in den Vordergrund. Eine relativ neue Regenerationsmethode ist die Ganzkörpertherapie auch „whole body cryotherapy“ (WBC) bzw. „partial body therapy“ (PBC) genannt. Ziel: Das Ziel dieser Masterarbeit war es die Auswirkungen von WBC bzw. PBC auf die Regenerations- und Leistungsfähigkeit bei Leistungs- und Freizeitsportler/innen zu beschreiben. Methodik: Die wissenschaftliche Fragestellung wurde anhand einer systematischen Literaturanalyse beantwortet. Dafür wurden relevante Studien aus der Online-Datenbank „PubMed“, nach diversen Auswahlkriterien („athlete“, „adults“, „whole body cryotheapy“, „partial body cryotherapy“, usw.) ausgesucht, analysiert und zur Beantwortung der Fragestellung herangezogen. Insgesamt wurden 82 Studien gefunden, von denen 22 alle Auswahlkriterien und die Anforderungen der Volltextanalyse erfüllten. Ergebnisse: In allen Studien wurde durch die WBC bzw. PBC die Körpertemperatur für circa 10 Minuten stark gesenkt. Durch diesen Effekt kam es zu verschiedenen physiologischen und leistungsspezifischen Auswirkungen, die jedoch nur selten zwischen den analysierten Studien einstimmig waren. So konnten bei der Laktatkonzentration, der maximale Sauerstoffaufnahme, der Kreatinkinase, das Myoglobin, dem C-reaktives Protein und bei verschiedenen Zytokinen keine eindeutigen Effekte nach WBC festgestellt werden. Insgesamt wurden vermehrt positive Effekte bei den Testosteronwerten, exzentrischen Belastungen, Sprintfähigkeit, maximalen Drehmoment, Schlageffizienz beim Tennis und Schmerzempfinden nach WBC beobachtet. Negative Auswirkungen nach WBC wurden nach einem Marathonlauf beschrieben. Schlussfolgerung: Trotz häufig diskutierter auch negativer Auswirkungen von Ganzkörperkälteinterventionen nach Belastung wurden im folgenden Review vor allem positive bzw. keine Auswirkungen auf die Regeneration- und Leistungsfähigkeit beobachtet. Abschließend soll erwähnt werden, dass es auf diesem Gebiet noch zu wenige Studien gibt, um zu aussagekräftigen Ergebnissen zu kommen.

description: Abstract Background The language of “participant-driven research,” “crowdsourcing” and “citizen science” is increasingly being used to encourage the public to become involved in research ventures as both subjects and scientists. Originally, these labels were invoked by volunteer research efforts propelled by amateurs outside of traditional research institutions and aimed at appealing to those looking for more “democratic,” “patient-centric,” or “lay” alternatives to the professional science establishment. As mainstream translational biomedical research requires increasingly larger participant pools, however, corporate, academic and governmental research programs are embracing this populist rhetoric to encourage wider public participation. Discussion We examine the ethical and social implications of this recruitment strategy. We begin by surveying examples of “citizen science” outside of biomedicine, as paradigmatic of the aspirations this democratizing rhetoric was originally meant to embody. Next, we discuss the ways these aspirations become articulated in the biomedical context, with a view to drawing out the multiple and potentially conflicting meanings of “public engagement” when citizens are also the subjects of the science. We then illustrate two uses of public engagement rhetoric to gain public support for national biomedical research efforts: its post-hoc use in the “care.data” project of the National Health Service in England, and its proactive uses in the “Precision Medicine Initiative” of the United States White House. These examples will serve as the basis for a normative analysis, discussing the potential ethical and social ramifications of this rhetoric. Summary We pay particular attention to the implications of government strategies that cultivate the idea that members of the public have a civic duty to participate in government-sponsored research initiatives. We argue that such initiatives should draw from policy frameworks that support normative analysis of the role of citizenry. And, we conclude it is imperative to make visible and clear the full spectrum of meanings of “citizen science,” the contexts in which it is used, and its demands with respect to participation, engagement, and governance.

description: Standard quantum state preparation methods work by preparing a required state locally and then distributing it to a distant location by a free-space propagation. We instead study procedures of preparing a target state at a remote location in the presence of an interacting background medium on which no control is required, manipulating only local dissipation. In mathematical terms, we characterize a set of reduced steady states stabilizable by local dissipation. An explicit local method is proposed by which one can construct a wanted one-site reduced steady state at an arbitrary remote site in a lattice of any size and geometry. In the chain geometry we also prove uniqueness of such a steady state. We demonstrate that the convergence time to fixed precision is smaller than the inverse gap, and we study robustness of the scheme in different medium interactions.

description: As one of the probes of universe, strong gravitational lensing systems allow us to compare different cosmological models and constrain vital cosmological parameters. This purpose can be reached from the dynamic and geometry properties of strong gravitational lensing systems, for instance, time-delay $Δτ$ of images, the velocity dispersion $σ$ of the lensing galaxies and the combination of these two effects, $Δτ/σ^2$. In this paper, in order to carry out one-on-one comparisons between $Λ$CDM universe and $R_h=ct$ universe, we use a sample containing 36 strong lensing systems with the measurement of velocity dispersion from the SLACS and LSD survey. Concerning the time-delay effect, 12 two-image lensing systems with $Δτ$ are also used. In addition, Monte Carlo (MC) simulations are used to compare the efficiency of the three methods as mentioned above. From simulations, we estimate the number of lenses required to rule out one model at the $99.7\%$ confidence level. Comparing with constraints from $Δτ$ and the velocity dispersion $σ$, we find that using $Δτ/σ^2$ can improve the discrimination between cosmological models. Despite the independence tests of these methods reveal a correlation between $Δτ/σ^2$ and $σ$, $Δτ/σ^2$ could be considered as an improved method of $σ$ if more data samples are available.

Creators: name: Hlisc, Daniel
Year: 2023

description: Da im Zuge von Demonstrationen gegen die Maßnahmen zur Bekämpfung von SARS-CoV-2 in Österreich und Deutschland nicht nur die Maßnahmen an sich kritisiert wurden, sondern von gewissen Personen auch Verschwörungsnarrative geäußert und höchst problematische historische Analogien konstruiert wurden, erfolgt in der vorliegenden Arbeit eine Analyse des Geschichtsbewusstseins dieser Protestierenden anhand konkreter Äußerungen. Dabei wird folgenden zwei Forschungsfragen nachgegangen: Welche Dimensionen der Sinnbildungsleistung im Geschichtsbewusstsein bestimmter Personen können dazu beigetragen haben 1) Analogien zwischen Abläufen/Praktiken/Gesetzen während der Zeit des Nationalsozialismus und Maßnahmen zur Bekämpfung von SARS-CoV-2 herzustellen. 2) mit antisemitischen Verschwörungsnarrativen das Aufkommen und die Bekämpfung von SARS-CoV-2 zu erklären. Als Methode werden die Kommunikationstheorie von Niklas Luhmann sowie die Hermeneutik nach Hans-Georg Gadamer herangezogen. Als theoretische Grundlage dienen die Ausführungen Jörn Rüsens zu den Dimensionen der Sinnbildungsleistung des Geschichtsbewusstseins. Die Analyse der Äußerungen legt den Schluss nahe, dass sich hierbei die Sinnbildung über die ästhetische, politische sowie moralische Dimension vollzogen haben könnte. Während die religiöse Dimension keine Rolle spielt, wurde die kognitive Dimension marginalisiert bzw. instrumentalisiert – beispielsweise durch revisionistische, pseudowissenschaftliche Inhalte, welche lediglich den eigenen Standpunkt bestätigen sollen, nicht aber wissenschaftlichen Kriterien entsprechen.

description: We study dark matter (DM) production in the mono-Z channel at the 13 TeV LHC both in an effective field theory framework as well as in simplified models with vector mediators, using a multivariate analysis. For DM-quark effective operators with scalar, vector, and tensor couplings and DM mass of 100 GeV, the 5$σ$ reach in the DM interaction scale $Λ$ is around 2, 1, and 3 TeV, respectively, for 3 ab$^{-1}$ and assuming a 5\% systematic uncertainty on the total background normalization. For simplified models with leptophobic vector mediators, the 5$σ$ reach for the mass of the mediator is 1.7 TeV also assuming a 5\% systematics and 3 ab$^{-1}$ of integrated luminosity. The reach for the dark matter interaction scale obtained with the multivariate analysis using a likelihood function discriminant is at least twice as high as that obtained from a simple cut and count analysis, once systematics on the background normalization larger than a few percent are taken into account. Moreover, the reach is much more stable against degradation due these systematic uncertainties.

description: BackgroundSequencing of both healthy and disease singletons yields many novel and low frequency variants of uncertain significance (VUS). Complete gene and genome sequencing by next generation sequencing (NGS) significantly increases the number of VUS detected. While prior studies have emphasized protein coding variants, non-coding sequence variants have also been proven to significantly contribute to high penetrance disorders, such as hereditary breast and ovarian cancer (HBOC). We present a strategy for analyzing different functional classes of non-coding variants based on information theory (IT) and prioritizing patients with large intragenic deletions.MethodsWe captured and enriched for coding and non-coding variants in genes known to harbor mutations that increase HBOC risk. Custom oligonucleotide baits spanning the complete coding, non-coding, and intergenic regions 10kb up- and downstream of ATM, BRCA1, BRCA2, CDH1, CHEK2, PALB2, and TP53 were synthesized for solution hybridization enrichment. Unique and divergent repetitive sequences were sequenced in 102 high-risk, anonymized patients without identified mutations in BRCA1/2. Aside from protein coding and copy number changes, IT-based sequence analysis was used to identify and prioritize pathogenic non-coding variants that occurred within sequence elements predicted to be recognized by proteins or protein complexes involved in mRNA splicing, transcription, and untranslated region (UTR) binding and structure. This approach was supplemented by in silico and laboratory analysis of UTR structure.Results15,311 unique variants were identified, of which 245 occurred in coding regions. With the unified IT-framework, 132 variants were identified and 87 functionally significant VUS were further prioritized. An intragenic 32.1kb interval in BRCA2 that was likely hemizygous was detected in one patient. We also identified 4 stop-gain variants and 3 reading-frame altering exonic insertions/deletions (indels).ConclusionsWe have presented a strategy for complete gene sequence analysis followed by a unified framework for interpreting non-coding variants that may affect gene expression. This approach distills large numbers of variants detected by NGS to a limited set of variants prioritized as potential deleterious changes.Electronic supplementary materialThe online version of this article (doi:10.1186/s12920-016-0178-5) contains supplementary material, which is available to authorized users.

A noncommutative version of the Julia-Wolff-Caratheodory Theorem

description: The classical Julia-Wolff-Carath{é}odory Theorem characterizes the behaviour of the derivative of an analytic self-map of a unit disc or of a half-plane of the complex plane at certain boundary points. We prove a version of this result that applies to noncommutative self-maps of noncommutative half-planes in von Neumann algebras at points of the distinguished boundary of the domain. Our result, somehow surprisingly, relies almost entirely on simple geometric properties of noncommutative half-planes, which are quite similar to certain geometric properties of classical hyperbolic spaces.
