The relevance of the article is due to the increased interest in the cultural heritage of the last century. The creative achievements and worldviews of priest Alexander Men, which are a significant component of the spiritual Russian culture, have been investigated. The works of Alexander are open to secular culture, science, to other faiths, non-Christian religions and deep church roots, they are accessible and simple for readers. Alexander Men did not create a special doctrine, because his main task was spiritual enlightenment and the exaltation of souls. Alexander Men was gifted not only with an analytical mind but also with a prophetic gift. Predictions about future are picked up by ignorant people and not only mislead them, but also become a source of distorted ideas about the Bible argued Alexander Men. First of all, Alexander Men in his researches seeks to answer the main questions that concern people, to reveal the very essence of the mysterious book of the Bible, to make its deep content not only a narrow circle of specialists, but also a wide reader. In the article a comprehensive analysis of the interpretation of the theologian's apocalyptic prophecies has been conducted. Alexander Men denies literal understanding of the Apocalypse images and emphasizes to allegorical character of this book. Numerous symbols, fantastic images and visions are revealed through the images of the prophetic books of the Old Testament. His initial thesis is to understand the Apocalypse as a permanent reality. Therefore, according to the theologian Alexander, apocalyptic prophecies are constantly being fulfilled and reproduced. The reasons for not accepting the apocalyptic reflections of Alexander Men by Orthodox priests have been defined: contradictory interpretations of Scripture, admiration for scientific facts, inclination for Catholicism, distortion of spiritual Orthodox practice, excessive liberalism, ecumenism, admiration for Western theology. However, Alexander Men played an important role in the Orthodox Church, he had many adherents (believers, priests, and researchers) and he is still mentioned in articles and conferences.

Objective: Unexpectedly wide distribution (90%) of hemoglobin oxygen saturation (sO2) within red cell concentrates (RCCs) has recently been observed. Causes of such variability are not yet completely explained whereas the roles of oxygen and oxidative lesions during the storage of RCCs are known. The objectives of the present study are to characterize sO2 distribution in RCCs produced in a Swiss blood center and to investigate the influence of processing and donors’ characteristics.Methods: The level of sO2 was measured in 1701 leukocyte-depleted RCCs derived from whole blood donations in both top–bottom (TB; component filtered, SAGM) and top–top (TT; whole blood filtration, PAGGSM) RCCs. The sO2 value was measured non-invasively through the PVC bag prior to storage by resonance Raman spectroscopy. Gender, age, blood type, hemoglobin level, and living altitude of donors, as well as process method and time-to-process were recorded.Results: Overall, the sO2 exhibited a wide non-Gaussian distribution with a mean of 51.2 ± 18.5%. Use of top-top kits resulted in a 16% higher sO2 (P < 0.0001) than with top-bottom ones. Waiting time before processing only had a modest impact, but the blood processing itself reduced the sO2 by almost 12% (P < 0.0001). sO2 was also significantly affected by some donors’ characteristics. RCCs from men exhibited 25% higher sO2 (P < 0.0001) than those donated by women. Multivariate analysis revealed that the apparent correlation observed with hemoglobin level and age was actually due to multicollinearity with the sex variable. Finally, we noticed no significant differences across blood type but found that altitude of residence was associated with the sO2 (i.e., higher in higher living place).Conclusion: These data confirm wide sO2 distribution in RCCs reported recently. The sO2 was impacted by the processing and also by donors’ characteristics such as the gender and the living altitude, but not by the hemoglobin level, blood group and donor age. This study provides new hints on the factors influencing red blood cells storage lesions, since they are known to be related to O2 content within the bags, giving clues to better process and to better store RCCs and therefore potentially improve the efficacy of transfusion.

Apocalyptic problems were relevant throughout the development of Christian culture. The content of apocalyptic works consisted mainly of eschatological revelations, that is, prophecies concerning the future of the end of the world. The book "Revelation of John" (Apocalypse) is an integral part of the New Testament Canon, and incorporates profound Christian ideas. During the research, the features of the modern scientific interpretation of the book "Revelation of John the Theologian" were revealed. The classical approaches to the interpretation of the book of the Apocalypse, their disadvantages and advantages were defined. The analysis of modern English, American and Russian Biblical studies on the interpretation of "Revelation of John the Theologian" was done. The book "Revelation of John" is the most eschatological work of the New Testament, which caused ambiguous reactions from the fathers and teachers of the early Church. Great attention was devoted to the commentary of the Apocalypse by Western Latin authors, reflecting the interest in this book in the Latin environment. As a result, starting from II century Christian authors read, commented and used the "Revelation of John." The importance of thoughtful use of interpretive approaches to the apocalypse's justification was first openly announced by the counter-reformatory authors of the end of XVI - beginning. XVII century. The development of domestic academic bible studies began at the Kiev Theological Academy. S. Solsky in his work "A brief essay on the history of sacred bibliology and exegesis" paid special attention to the history of the interpretation of the Scriptures. Among contemporary domestic researchers, in this context scientific achievements of S. Holovashchenko should be noted. Among the main general principles of modern biblical hermeneutics, he defined: a critical study of the text, an important idea of the author's personality, grammatical and philological analysis of the text, definition of the literary genre, establishing the original authentic meaning of the text first, and then clarifying its present relevance. English and American Bibleists are engaged in a detailed study of apocalyptic problems and their studies are considered the most systematic in our time.

Rationale: Characterization of Regolith And Trace Economic Resources (CRATER), an Orbitrap™‐based laser desorption mass spectrometry instrument designed to conduct high‐precision, spatially resolved analyses of planetary materials, is capable of answering outstanding science questions about the Moon's formation and the subsequent processes that have modified its (sub)surface. Methods: Here, we describe the baseline design of the CRATER flight model, which requires <20 000 cm3 volume, <10 kg mass, and <60 W peak power. The analytical capabilities and performance metrics of a prototype that meets the full functionality of the flight model are demonstrated. Results: The instrument comprises a high‐power, solid‐state, pulsed ultraviolet (213 nm) laser source to ablate the surface of the lunar sample, a custom ion optical interface to accelerate and collimate the ions produced at the ablation site, and an Orbitrap mass analyzer capable of discriminating competing isobars via ultrahigh mass resolution and high mass accuracy. The CRATER instrument can measure elemental and isotopic abundances and characterize the organic content of lunar surface samples, as well as identify economically valuable resources for future exploration. Conclusion: An engineering test unit of the flight model is currently in development to serve as a pathfinder for near‐term mission opportunities. [ABSTRACT FROM AUTHOR]

The article deals with the main apocalyptic themes and motives in the modern religious literature of Jehovah's Witnesses and Seventh-day of Adventists. The relevance of the apocalyptic perspective in the light of the acute problems of the present, in particular, in the context of the global world situation, is indicated. Author analyzed global problems in accordance with certain Biblical signs of "time of the end", apocalyptic feelings and expectations in the religious literature of Jehovah's Witnesses and Seventh-day of Adventists. A comparative analysis reveals the common and distinctive features of apocalyptic themes, plots and moods in the religious literature of Jehovah's Witnesses and Seventh-day of Adventists. In this research author used general scientific and special methods. The main research approach was the systematic approach, which allowed integrating the diversity of the investigated material into apocalyptic problems in the field of philosophy and theology in order to carry out a coherent definition of the main themes and motifs in the Protestant literature. A comparative method was also used in this research. The main ideas in the religious literature of Jehovah's Witnesses in this context are: the proclamation of the Second Coming of Christ on Earth during the crisis periods; emphasis on the Millennial Kingdom in the Sky, the opposition of secular power to the Divine Structure. Seventh-day Adventist сoncept: judgment, Second Coming of Jesus Christ, first resurrection and ascension of saints; Armageddon, the devastation of the earth and the destruction of the wicked; Millennial kingdom of the righteous in heaven; The second resurrection and the last judgment; New Land.

Background: HEALWA is an online library of evidence-based health information resources that are available to Washington state health practitioners. To increase awareness and use of HEALWA among health practitioners in rural areas, the National Network of Libraries of Medicine Pacific Northwest Region and Washington State University Spokane co-funded an outreach librarian position to provide instruction on using HEALWA. Case Presentation: After attempts at frequent in-person workshops failed due to lack of attendance, a one-hour-long webinar targeted at rural nurses was developed to be delivered once a month. These webinars introduced participating health professionals to HEALWA, including how to set up their access and how to navigate the resource. To accommodate the busy schedules and different learning styles of the target audience, the workshops occurred both as monthly webinars and in-person, when available, in addition to an online self-guided tutorial. Continuing education credit was obtained through the Washington State Nurses Association, and a partnership with the Washington State Nursing Commission improved promotion of the webinars. Evaluations for both the webinars and workshops have been largely positive. Conclusions: The webinar series, coupled with in-person workshops and an online tutorial, reached nurses in rural areas of Washington state to increase awareness of HEALWA. To further facilitate access to HEALWA instruction, a recorded version of the live webinar is in development.

After blood donation, the red blood cells (RBCs) for transfusion are generally isolated by centrifugation and then filtrated and supplemented with additive solution. The consecutive changes of the extracellular environment participate to the occurrence of storage lesions. In this study, the hypothesis is that restoring physiological levels of uric and ascorbic acids (major plasmatic antioxidants) might correct metabolism defects and protect RBCs from the very beginning of the storage period, to maintain their quality. Leukoreduced CPD-SAGM RBC concentrates were supplemented with 416 µM uric acid and 114 µM ascorbic acid and stored during six weeks at 4 °C. Different markers, i.e., haematological parameters, metabolism, sensitivity to oxidative stress, morphology and haemolysis were analyzed. Quantitative metabolomic analysis of targeted intracellular metabolites demonstrated a direct modification of several metabolite levels following antioxidant supplementation. No significant differences were observed for the other markers. In conclusion, the results obtained show that uric and ascorbic acids supplementation partially prevented the metabolic shift triggered by plasma depletion that occurs during the RBC concentrate preparation. The treatment directly and indirectly sustains the antioxidant protective system of the stored RBCs.

Purpose: Medical libraries need to actively review their service models and explore partnerships with other campus entities to provide better-coordinated clinical research management services to faculty and researchers. TRAIL (Translational Research and Information Lab), a five-partner initiative at the University of Washington (UW), explores how best to leverage existing expertise and space to deliver clinical research data management (CRDM) services and emerging technology support to clinical researchers at UW and collaborating institutions in the Pacific Northwest. Methods: The initiative offers 14 services and a technology-enhanced innovation lab located in the Health Sciences Library (HSL) to support the University of Washington clinical and research enterprise. Sharing of staff and resources merges library and non-library workflows, better coordinating data and innovation services to clinical researchers. Librarians have adopted new roles in CRDM, such as providing user support and training for UW’s Research Electronic Data Capture (REDCap) instance. Results: TRAIL staff are quickly adapting to changing workflows and shared services, including teaching classes on tools used to manage clinical research data. Researcher interest in TRAIL has sparked new collaborative initiatives and service offerings. Marketing and promotion will be important for raising researchers’ awareness of available services.Conclusions: Medical librarians are developing new skills by supporting and teaching CRDM. Clinical and data librarians better understand the information needs of clinical and translational researchers by being involved in the earlier stages of the research cycle and identifying technologies that can improve healthcare outcomes. At health sciences libraries, leveraging existing resources and bringing services together is central to how university medical librarians will operate in the future.

Bardyn, Tania P., Resnick, Taryn, and Camina, Susan K.
- Abstract
How translational researchers use data is becoming an important support function for libraries to understand. Libraries' roles in this increasingly complex area of Web librarianship are often unclearly defined. The authors conducted two focus groups with physicians and researchers at an academic medical center, the UCLA David Geffen School of Medicine, to gain a better understanding of the current state of data use and data management practices among translational researchers. Data management practices varied widely among departments, disciplines, and research centers, but common areas of concern important to Web librarianship included privacy, data access, and data stewardship. The results provided qualitative information about creating, managing, maintaining, and validating data in clinical and research environments, and challenges working with clinical research data in universities. These results inform current practices around data access, data sharing, and privacy of research participant data. Libraries can build on existing Web skills by instructing users how to find open source and commercial data sets, partnering to establish and implement improved data collection and archiving practices, and teaching principles of ethical data use.

29. Library Blogs: What's Most Important for Success within the Enterprise?
- Author

Bardyn, Tania P.
- Abstract
Library blogs exchange information and ideas on everything from the everyday, such as library services, to the profound, such as values held by librarians (high-quality reliable resources, academic freedom, open access, and so on). According to medical librarians who maintain library blogs, a typical month includes two to four contributors writing and posting about two to four posts--but barely any feedback. In fact, only one out of 22 blogs surveyed received comments on a regular basis, suggesting that almost all librarian bloggers these days find themselves struggling with the problems of how to integrate content into the enterprise and how to engage users in library initiatives. So should library management support blogs in the enterprise? The answer is yes. Of course, this presumes two "givens": (1) an adequate blog software package; and (2) creative librarians. If these two givens are not present in the organization, they must be addressed before there are any major efforts to implement and sustain a successful library blog in an enterprise. The library organization's leaders and management team are responsible for understanding, establishing, and managing the following five factors for library blog implementation and sustainable success: (1) The library organization's strategies, objectives, and plans are "clear" and "well-conceived"; (2) The library organization understands the complicated nature of the "value proposition" of a blog within the enterprise; (3) "Multiple supporting enterprise initiatives" have been incorporated into the blog; (4) Librarians continuously "engage" library management in improving the blog and related workflows; and (5) The library organization invests in "advertent" IT experimentation. These factors are for every manager who supervises librarians who blog or lead Web 2.0 initiatives and are in addition to the two givens.

- Abstract
Librarians at New York City's Bellevue Hospital Center needed to write a 3-year strategic plan that included technology data. In this article, they describe how they surveyed doctors and residents about their technology and internet use to determine what the Bellevue Medical Library needed to do in order to support those who deliver medical care. Specifically, they needed to know where doctors use computers, why and where they use the internet, and where they search for information. They explain how they chose survey questions, reveal what they learned from the doctors' completed surveys, and describe how that data was used to plan services. The results helped them write their plan and justify a big budget increase to purchase more computers. Five tips are presented for writing survey questions about technology and internet use.

The COSIMA instrument onboard the Rosetta spacecraft collected and analyzed samples of individual particles from the coma of Comet67P/ Churyumov-Gerasimenko. Initial results of the analysis of several particles have been presented elsewhere while analyses of the organic component of the dust particles has been shown to compare favor ably to laboratory spectra of IOM extracted from the Orguil and Murchison meteorites. Here we will compare the spectra of the same two particles to laboratory spectra of organic grain coatings produced via Surface Mediated Reactions of CO, H2 and N2 on amorphous iron silicate grains.

Persistent budget deficits and extremely high interest rates (while inflation remains relatively low) have been a distinct feature of the 2010–2013 period in Ukraine. By using a statistical technique of the vector autoregressive − vector error correction (VAR/VEC) model, it is established that: a) the budget deficit is a factor behind the exchange rate depreciation and an increase in the interest rate, with a very strong contractionary effect on output; b) a higher interest rate contributes to worsening of the budget balance and a significant decrease in output (both are standard macroeconomic relationships); c) nominal exchange rate depreciation permanently widens the budget deficit, combined with a temporary increase in the interest rate and short-lived output contraction. It is worth noting that upward interest rate pressure is the only statistically significant effect of a positive output shock. According to the variance decomposition, the budget balance determines up to 50% and the interest rate upwards of 40% of changes in the output, respectively. It is confirmed that an increase in output is of marginal importance for the budget balance. On the whole, our findings argue in favour of fiscal discipline in Ukraine as a stabilisation policy tool.

Physics ,QC1-999 - Abstract
The mixedness of a quantum state is usually seen as an adversary to topological quantization of observables. For example, exact quantization of the charge transported in a so-called Thouless adiabatic pump is lifted at any finite temperature in symmetry-protected topological insulators. Here, we show that certain directly observable many-body correlators preserve the integrity of topological invariants for mixed Gaussian quantum states in one dimension. Our approach relies on the expectation value of the many-body momentum-translation operator and leads to a physical observable—the “ensemble geometric phase” (EGP)—which represents a bona fide geometric phase for mixed quantum states, in the thermodynamic limit. In cyclic protocols, the EGP provides a topologically quantized observable that detects encircled spectral singularities (“purity-gap” closing points) of density matrices. While we identify the many-body nature of the EGP as a key ingredient, we propose a conceptually simple, interferometric setup to directly measure the latter in experiments with mesoscopic ensembles of ultracold atoms.

The D/H ratio is a clue to the origin and evolution of hydrogen-bearing chemical species in Solar system materials. D/H has been observed in the coma of many comets, but most such measurements have been for gaseous water. We present the first in situ measurements of the D/H ratios in the organic refractory component of cometary dust particles collected at very low impact speeds in the coma of comet 67P/Churyumov-Gerasimenko (hereafter 67P) by the COSIMA instrument onboard Rosetta. The values measured by COSIMA are spatial averages over an approximately 35 × 50 µm2 area. The average D/H ratio for the 25 measured particles is (1.57 ± 0.54) × 10−3, about an order of magnitude higher than the Vienna Standard Mean Ocean Water (VSMOW), but more than an order of magnitude lower than the values measured in gas-phase organics in solar-like protostellar regions and hot cores. This relatively high averaged value suggests that refractory carbonaceous matter in comet 67P is less processed than the most primitive insoluble organic matter (IOM) in meteorites, which has a D/H ratio in the range of about 1 to 7 × 10−4. The cometary particles measured in situ also have a higher H/C ratio than the IOM. We deduce that the measured D/H in cometary refractory organics is an inheritance from the presolar molecular cloud from which the Solar system formed. The high D/H ratios observed in the cometary particles challenges models in which high D/H ratios result solely from processes that operated in the protosolar disc.

Here, we report the detection of phosphorus and fluorine in solid particles collected from the inner coma of comet 67P/Churyumov-Gerasimenko measured with the COmetary Secondary Ion Mass Analyser (COSIMA) instrument on-board the Rosetta spacecraft, only a few kilometers away from the comet nucleus. We have detected phosphorus-containing minerals from the presented COSIMA mass spectra, and can rule out e.g. apatite minerals as the source of phosphorus. This result completes the detection of life-necessary CHNOPS-elements in solid cometary matter, indicating cometary delivery as a potential source of these elements to the young Earth. Fluorine was also detected with CF$^+$ secondary ions originating from the cometary dust., 5 pages, 1 figure, 1 table, supplementary 2 tables and 2 figures

Physics ,QC1-999 - Abstract
External driving is emerging as a promising tool for exploring new phases in quantum systems. The intrinsically nonequilibrium states that result, however, are challenging to describe and control. We study the steady states of a periodically driven one-dimensional electronic system, including the effects of radiative recombination, electron-phonon interactions, and the coupling to an external fermionic reservoir. Using a kinetic equation for the populations of the Floquet eigenstates, we show that the steady-state distribution can be controlled using the momentum and energy relaxation pathways provided by the coupling to phonon and Fermi reservoirs. In order to utilize the latter, we propose to couple the system and reservoir via an energy filter which suppresses photon-assisted tunneling. Importantly, coupling to these reservoirs yields a steady state resembling a band insulator in the Floquet basis. The system exhibits incompressible behavior, while hosting a small density of excitations. We discuss transport signatures and describe the regimes where insulating behavior is obtained. Our results give promise for realizing Floquet topological insulators.

Physics ,QC1-999 - Abstract
The interaction between light and matter can give rise to novel topological states. This principle was recently exemplified in Floquet topological insulators, where classical light was used to induce a topological electronic band structure. Here, in contrast, we show that mixing single photons with excitons can result in new topological polaritonic states—or “topolaritons.” Taken separately, the underlying photons and excitons are topologically trivial. Combined appropriately, however, they give rise to nontrivial polaritonic bands with chiral edge modes allowing for unidirectional polariton propagation. The main ingredient in our construction is an exciton-photon coupling with a phase that winds in momentum space. We demonstrate how this winding emerges from the finite-momentum mixing between s-type and p-type bands in the electronic system and an applied Zeeman field. We discuss the requirements for obtaining a sizable topological gap in the polariton spectrum and propose practical ways to realize topolaritons in semiconductor quantum wells and monolayer transition metal dichalcogenides.

The instrument COSIMA (COmetary Secondary Ion Mass Analyzer) onboard of the European Space Agency mission Rosetta collected and analyzed dust particles in the neighborhood of comet 67P/Churyumov‐Gerasimenko. The chemical composition of the particle surfaces was characterized by time‐of‐flight secondary ion mass spectrometry. A set of 2213 spectra has been selected, and relative abundances for CH‐containing positive ions as well as positive elemental ions define a set of multivariate data with nine variables. Evaluation by complementary chemometric techniques shows different compositions of sample groups collected during two periods of the mission. The first period was August to November 2014 (far from the Sun); the second period was January 2015 to February 2016 (nearer to the Sun). The applied data evaluation methods consider the compositional nature of the mass spectral data and comprise robust principal component analysis as well as classification with discriminant partial least squares regression, k‐nearest neighbor search, and random forest decision trees. The results indicate a high importance of the relative abundances of the secondary ions C+ and Fe+ for the group separation and demonstrate an enhanced content of carbon‐containing substances in samples collected in the period with smaller distances to the Sun., Extraterrestrial dust particles from the neighborhood of comet 67P/Churyumov‐Gerasimenko have been collected by the instrument COSIMA onboard of the European Space Agency mission Rosetta. The composition of the particles was characterized by time‐of‐flight secondary ion mass spectrometry giving evidence of minerals and macromolecular organic substances. A specific multivariate evaluation of the mass spectral data by chemometric methods indicates an enhanced content of carbon‐containing substances in samples collected in a period with smaller distances to the Sun.
