Modeling of Spray Cooling with a Moving Steel Slab during the Continuous Casting Process
Authors: Ma Haibo , Lee Justina , Tang Kaile , Liu Rui , Lowry Michael , Silaen Armin , Zhou Chenn Q.
Published: October 2018

During continuous casting secondary cooling, heat is removed from slab surface through spraying water from arrays of nozzles. Efficient and uniform heat removal without causing slab cracking is desired. The present study focuses on the development and validation of a reliable numerical model which can accurately predict spray formation from flat‐fan atomizers and the heat transfer between impinging droplets and a moving hot steel slab. Water droplets are considered as the discrete phase and are tracked in a Lagrangian framework to allow detailed modeling of breakup, coalescence, and impingement. The droplet size and the heat transfer coefficient on the slab surface are validated. Both simulations show good agreements with the experimental measurements in the center of the spray, where fine droplets are generated through multiple collisions. After droplets impinge on the slab surface, a narrow low temperature region is created inside the spray coverage, and the relative motion of the spray shifts the coverage toward the upstream. Future studies are necessary in order to improve the prediction of droplet‐air interaction near the edge of the spray, where small droplets tend to coalesce and form large ones due to a lower possibility of collision.
As Easy as ABC? Teaching and Learning About Letters in Early Literacy
Authors: Kaye Elizabeth L. , Lose Mary K.
Published: October 2018

Letter learning is nuanced, complex, and essential to the development of an effective literacy processing system. Forming and naming letters, rapidly differentiating between visually similar letters, and recognizing their sound correspondences are foundational to becoming a reader and writer. Indeed, control over letters affects monitoring, searching, and self‐correcting in reading and writing. The authors argue for (a) assessment that monitors evolving letter knowledge, (b) instruction that is focused and brief and capitalizes on students’ unique strengths and ways of knowing, and (c) isolated letter work that is balanced with the use of authentic texts. Transcripts of teacher–student interactions during reading and writing, personal alphabet books, magnetic letter sorts, and links to teacher resources illustrate how letter learning can be fostered in a variety of activity settings while ensuring student engagement and supporting overall literacy development.

Published: October 2018

Introduction

Evidence indicates that associations between diet and Alzheimer's disease may occur through biomarker pathways such as amyloid‐β (Aβ); however, few studies have investigated dietary/Aβ relationships, and no study has investigated this relationship in women.

Methods

Dietary patterns were extrapolated for 115 participants from the Women's Health Aging Project. Aβ deposition was measured via in vivo F‐18 florbetaben positron emission tomography scanning.

Results

Participants were, on average, aged 70 years (±2.63 SD), had 13 years of education (±3.57 SD), a BMI of 28 kg/m2 (±5.46 SD), and a daily energy intake of 5161 kJ (±1679.03 SD). Four dietary patterns were identified: high fat, Mediterranean, junk food, and low fat. Adherence to the junk food diet was a significant predictor of Aβ deposition (β = .10, P = .03).

Discussion

This study highlights the potential of diet to influence neurodegenerative disease and as a potential modifiable lifestyle risk factor for Alzheimer's disease.
Correlates of expected eMental Health intervention uptake among Filipino domestic workers in China
Authors: Hall Brian J. , Shi Wei , Garabiles Melissa R. , Chan Edward W. W.
Published: October 2018

Background.

Transnational migrant populations face critical barriers to mental health service utilization that perpetuate mental health disparities globally. Overseas Filipino workers (OFWs) number over 2 million globally and 25% are female domestic workers. Structural barriers prevent equitable access to mental health services for this population. Electronic mental health (eMental Health) intervention is a scalable alternative to face-to-face treatment. The current study sought to identify key correlates of intention to use eMental Health within a community of female Filipino domestic workers living and working in Macao (SAR), China.

Methods.

Respondent-driven sampling implemented at a community field site was used to reach a sample of 1364 female domestic workers. A multivariable adjusted partial proportional-odds (PPO) model was used to assess relevant correlates of intent to use eMental Health.

Results.

The majority (62.8%) reported being likely to utilize eMental Health. The adjusted PPO model showed that younger age (18–25, 26–35, 36–45v.over 55), longer time as an OFW, being likely (v.neutral and unlikely) to seek professional services, willingness to pay for services (v.not), belief that mental health services are a priority (v.low priority), having access to Wi-Fi outside the employer's home (v.not), and higher levels of social support were associated with increased odds of intent to use eMental Health.

Conclusions.

eMental Health is a promising intervention with high potential for uptake among OFWs. The majority of the study population owned a smartphone and were able to connect to the Internet or Wi-Fi. Future work will rigorously evaluate eMental Health programs for use among OFWs.

Authors: Ghazali Aiham Daniel , Deilhes Elsa , Thomas Julie , Laland Catherine , Thévenot Sarah , Richer Jean Pierre , Oriot Denis
Published: October 2018

Background

Hand hygiene is the primary measure for reducing nosocomial infections based on 7 steps recommended by the WHO. The aim of this study was to assess the duration and the quality of hand hygiene before and after simulation-based training (SBT).

Methods

The study took place in a University Hospital Pediatric Department among its residents and nurses. In assessment A, 10 hand-rubbing procedures per participant during a work day were scored by observers using a validated, anatomically based assessment scale. Two weeks later, all participants received a didactic course and SBT, followed 1 month later by assessment B, observation of 10 hand-rubbing procedures. Assessments were performed by 2 independent observers. Before-and-after testing was used to evaluate the demonstration of theoretical knowledge.

Results

In total, 22 participants were included, for whom 438 hand hygiene procedures were assessed: 218 for assessment A and 220 for assessment B. The duration of hand rubbing increased from 31.16 seconds in assessment A to 35.75 seconds in assessment B (P=.04). In assessment A, participants averaged 6.33 steps, and in assessment B, participants averaged 6.03 steps (difference not significant). Significant improvement in scores was observed between assessments A and B, except for the dorsal side of the right hand. The wrist and interdigital areas were the least-cleaned zones. A difference between assessments A and B was observed for nail varnish (P=.003) but not for long nails or jewelry. Theoretical scores increased from 2.83 to 4.29 (scale of 0–5; P<.001).

Conclusion

This study revealed that an optimal number of steps were performed during hand-rubbing procedures and that SBT improved the duration and quality of hand hygiene, except for the dorsal right side. Emphasis should be placed on the specific hand areas that remained unclean after regular hand-rubbing procedures.
New data from Jebel Moya and Shaqadud (central Sudan): implications for Late Mesolithic interconnectivity with the Sahara
Authors: Brass Michael , Adam Ahmed H. A. , Wellings Joss
Published: October 2018

Building upon Brass’ previous research on Jebel Moya, which included a comprehensive reanalysis of the pottery from Wellcome's 1911–14 expeditions curated at the British Museum, new research activities by the University College London–University of Khartoum–NCAM Expedition to the Southern Gezira project have included locating and examining for the first time the Late Mesolithic sherds from Jebel Moya curated at the National Museum in Khartoum. Representative samples from the sites of Shaqadud Midden and Shaqadud S21 at the British Museum have also been re-examined. The aims of these activities were threefold: to test the reliability and cohesiveness of and patterning in the Shaqadud collection through the expanded application of attribute analysis, to determine if Caneva's observations of décor patterns on Jebel Moya's Late Mesolithic sherds could be replicated and to obtain better visibility into the nature of its pottery assemblage from this time, and to use the resulting data to test the viability of the central Sudan being a fulcrum of cultural interchanges during the late sixth and early fifth millennium BC. We conclude that there was a piecemeal establishment of networks along which there was diffusion of ideas and animals, and perhaps low numbers of people, into the central and south-central Sudan.
The drivers and consequences of unstablePlasmodiumdynamics: a long-term study of three malaria parasite species infecting a tropical lizard
Authors: Otero Luisa , Schall Jos J. , Cruz Virnaliz , Aaltonen Kristen , Acevedo Miguel A.
Published: October 2018

Understanding the consequences of environmental fluctuations for parasite dynamics requires a long-term view stretching over many transmission cycles. Here we studied the dynamics of three malaria parasites (Plasmodium azurophilum,P. leucocyticaandP. floridense) infecting the lizardAnolis gundlachi, in the rainforest of Puerto Rico. In this malaria–anole system we evaluated temporal fluctuations in individual probability of infection, the environmental drivers of observed variation and consequences for host body condition andPlasmodiumparasites assemblage. We conducted a total of 15 surveys including 10 from 1990 to 2002 and five from 2015 to 2017. During the early years, a lizard's probability of infection by allPlasmodiumspecies appeared stable despite disturbances ranging from two hurricanes to short droughts. Over a longer timescale, probability of infection and overall prevalence varied significantly, following non-linear relationships with temperature and rainfall such that highest prevalence is expected at intermediate climate measures. A perplexing result was that host body condition was maximized at intermediate levels of rainfall and/or temperature (when risk of infection was highest), yet we found no significant decreases in body condition due to infection.Plasmodiumparasite species composition varied through time with a reduction and near local extinction ofP. floridense. Our results emphasize the need for long-term studies to reveal host–parasite dynamics, their drivers and consequences.
CoStorm: a term map system to aid in a collaborative ideation process
Authors: Zhang Chengwei , López-Parra Marcelo , Chen Junyu , Tian Ling
Published: October 2018

The decisions made during the early stages of a design process have a huge impact on a product. Owing to the explosion of preliminary ideas, however, designers easily lose track of important ideas and significant information and end up being buried in a pile of plain words. Failing to locate an idea in the context of idea generation makes it difficult to generate new ideas or take optimized decisions. In this study, the authors propose the term map approach to provide a complete bird's eye view of all ideas, which is a higher-dimension graphical representation that helps in inspiring ideas and making decisions among design team members. A software application named CoStorm is developed. Through the case study of the cash-flattener module, which is a crucial component of an automated teller machine, this method is found to contribute in facilitating the ideation and decision-making progress.
Frontal Subduction of the Mid‐Atlantic Bight Shelf Water at the Onshore Edge of a Warm‐Core Ring
Authors: Zhang Weifeng G. , Partida Jacob
Published: October 2018

This work studies the subduction of the shelf water along the onshore edge of a warm‐core ring that impinges on the edge of the Mid‐Atlantic Bight continental shelf. The dynamical analysis is based on observations by satellites and from the Ocean Observatories Initiative Pioneer Array observatory as well as idealized numerical model simulations. They together show that frontogenesis‐induced submesoscale frontal subduction with order‐one Rossby and Froude numbers occurs on the onshore edge of the ring. The subduction flow results from the onshore migration of the warm‐core ring that intensifies the density front on the interface of the ring and shelf waters. The subduction is a part of the cross‐front secondary circulation trying to relax the intensifying density front. The dramatically different physical and biogeochemical properties of the ring and shelf waters provide a great opportunity to visualize the subduction phenomenon. Entrained by the ring‐edge current, the subducted shelf water is subsequently transported offshore below a surface layer of ring water and alongside of the surface‐visible shelf‐water streamer. It explains the historical observations of isolated subsurface packets of shelf water along the ring periphery in the slope sea. Model‐based estimate suggests that this type of subduction‐associated subsurface cross‐shelfbreak transport of the shelf water could be substantial relative to other major forms of shelfbreak water exchange. This study also proposes that outward spreading of the ring‐edge front by the frontal subduction may facilitate entrainment of the shelf water by the ring‐edge current and enhances the shelf‐water streamer transport at the shelf edge.

Published: October 2018

Despite the significance of biogenic methane generation in coal beds, there has never been a systematic long-term evaluation of the ecological response to biostimulation for enhanced methanogenesis in situ. Biostimulation tests in a gas-free coal seam were analysed over 1.5 years encompassing methane production, cell abundance, planktonic and surface associated community composition and chemical parameters of the coal formation water. Evidence is presented that sulfate reducing bacteria are energy limited whilst methanogenic archaea are nutrient limited. Methane production was highest in a nutrient amended well after an oxic preincubation phase to enhance coal biofragmentation (calcium peroxide amendment). Compound-specific isotope analyses indicated the predominance of acetoclastic methanogenesis. Acetoclastic methanogenic archaea of the Methanosaeta and Methanosarcina genera increased with methane concentration. Acetate was the main precursor for methanogenesis, however more acetate was consumed than methane produced in an acetate amended well. DNA stable isotope probing showed incorporation of 13C-labelled acetate into methanogenic archaea, Geobacter species and sulfate reducing bacteria. Community characterisation of coal surfaces confirmed that methanogenic archaea make up a substantial proportion of coal associated biofilm communities. Ultimately, methane production from a gas-free subbituminous coal seam was stimulated despite high concentrations of sulfate and sulfate-reducing bacteria in the coal formation water. These findings provide a new conceptual framework for understanding the coal reservoir biosphere.

Reversible and nonvolatile electric-field control of the physical properties of topological insulators is essential for fundamental research and development of practical electronic devices. Here, we report the integration of topological insulator films with ferroelectric Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) single crystals in the form of ferroelectric field-effect devices that allow us to tune the electronic properties of topological insulator films in a reversible and nonvolatile manner. Specifically, gating of Cr-doped Bi2Se3 films with the PMN-PT layer is shown to provide a means to reversibly tune and modulate the carrier density and carrier type, as well as its other properties, such as the conductance, magnetoconductance, Fermi level, phase coherence length, and screening factor of electron–electron interaction by polarization switching at room temperature. These findings provide a simple and direct approach for probing the quantum transport properties of topological insulator films through ferroelectric gating by using PMN-PT. The combination of topological insulators with both ferroelectrically and piezoelectrically active PMN-PT thus offers a promising step toward exploring topological insulator/ferroelectric(piezoelectric) hybrid devices that could utilize not only the ferroelectric field-effect of topological insulator/PMN-PT structures but also the unique properties of respective materials.

Multi environment testing helps identify stable genotypes especially for adverse abiotic stress situations. In the era of climate change and multiple abiotic stresses, it becomes important to analyze stability of rice lines under both irrigated and stress conditions. Mutants are an important genetic resource which can help in revealing the basis of natural variation. We analyzed 300 EMS induced mutants of aus rice cultivar Nagina22 (N22) for their G × E interaction and stability under low phosphorus (P), water limited and irrigated conditions. Environmental effect and interaction were more significant than genotypic contribution on grain yield (GY), productive tillers (TN) and plant height (PH) under these three environmental conditions in dry season, 2010. GY and TN were more affected by low P stress than by water limited condition, but PH was not significantly different under these two stresses. Mutants G17, G209, G29, G91, G63 and G32 were stable for GY in decreasing order of stability across the three environments but G254 and G50 were stable only in low P, G17 and G45 only in water limited and G295 and G289 only in normal irrigated condition. We then selected and evaluated 3 high yielding mutants, 3 low yielding mutants and N22 for their stability and adaptability to these 3 environments in both wet and dry seasons for six years (2010–2015). The most stable lines based on the combined analysis of 12 seasons were G125 (NH210) under normal condition, G17 (NH686), G176 (NH363) and G284 (NH162) in low P condition and G176 (NH363) under water limited condition. G176 was the best considering all 3 conditions. When screened for 15 Pup1 gene-specific markers, G176 showed alleles similar to N22. While two other low-P tolerant lines G17 and G65 showed N22 similar alleles only at k-1 and k-5 but a different allele or null allele at 13 other loci. These stable mutants are a valuable resource for varietal development and to discover genes for tolerance to multiple abiotic stresses.

Hepatitis C virus (HCV) exploits an extensive network of host proteins to maintain chronic infection. Using RNA-Seq technology, we identified 30 host genes that were differentially expressed in cell culture grown HCV (HCVcc)-infected cells. Of these candidate genes, we selected solute carrier family 3 member 2 (SLC3A2) for further investigation. SLC3A2, also known as CD98hc, is a member of the solute carrier family and encodes a subunit of heterodimeric amino acid transporter. SLC3A2 and LAT1 constitute a heterodimeric transmembrane protein complex that catalyzes amino acid transport. In this study, we showed that HCV upregulated both mRNA and protein expression levels of SLC3A2 and this upregulation occurred through NS3/4A-mediated oxidative stress. HCV also elevated SLC3A2/LAT1 complex level and thus mammalian target of rapamycin complex 1 (mTORC1) signaling was activated. We further showed that L-leucine transport level was significantly increased in Jc1-infected cells as compared with mock-infected cells. Using RNA interference technology, we demonstrated that SLC3A2 was specifically required for the entry step but not for other stages of the HCV life cycle. These data suggest that SLC3A2 plays an important role in regulating HCV entry. Collectively, HCV exploits SLC3A2 for viral propagation and upregulation of SLC3A2 may contribute to HCV-mediated pathogenesis.

Dynamics of multiple protoplanets embedded in gas and pebble discs and its dependence on Σ and ν parameters
Authors: Brož M. , Chrenko O. , Nesvorný D. , Lambrechts M.
Published: October 2018

Protoplanets of super-Earth size may get trapped in convergence zones for planetary migration and form gas giants there. These growing planets undergo accretion heating, which triggers a hot-trail effect that can reverse migration directions, increase planetary eccentricities, and prevent resonant captures of migrating planets. In this work, we study populations of embryos that are accreting pebbles under different conditions, by changing the surface density, viscosity, pebble flux, mass, and the number of protoplanets. For modelling, we used the FARGO-THORIN two-dimensional (2D) hydrocode, which incorporates a pebble disc as a second pressure-less fluid, the coupling between the gas and pebbles, and the flux-limited diffusion approximation for radiative transfer. We find that massive embryos embedded in a disc with high surface density (Σ = 990 g cm−2 at 5.2 au) undergo numerous “unsuccessful” two-body encounters that do not lead to a merger. Only when a third protoplanet arrives in the convergence zone do three-body encounters lead to mergers. For a low-viscosity disc (ν = 5 × 1013 cm2 s−1), a massive co-orbital is a possible outcome, for which a pebble isolation develops and the co-orbital is further stabilised. For more massive protoplanets (5 M⊕), the convergence radius is located further out, in the ice-giant zone. After a series of encounters, there is an evolution driven by a dynamical torque of a tadpole region, which is systematically repeated several times until the co-orbital configuration is disrupted and planets merge. This may be a way to solve the problem that co-orbitals often form in simulations but they are not observed in nature. In contrast, the joint evolution of 120 low-mass protoplanets (0.1 M⊕) reveals completely different dynamics. The evolution is no longer smooth, but rather a random walk. This is because the spiral arms, developed in the gas disc due to Lindblad resonances, overlap with each other and affect not only a single protoplanet but several in the surrounding area. Our hydrodynamical simulations may have important implications for N-body simulations of planetary migration that use simplified torque prescriptions and are thus unable to capture protoplanet dynamics in its full glory.
Radiation-resistant materials based on mica in the construction industry
Authors: Shishelova Tamara , Zhitov V.
Published: October 2018

Burial of radioactive waste is an urgent contemporary problem. The development of materials for the disposal of radioactive waste is also topical. In this paper, we consider the possibility of using mica to solve these problems. Mica has been known for a long time and studied by researchers from almost all countries of the world. The areas of its use are constantly expanding and renewing. Mica has high electrical insulation properties. Because of this, the field of application of mica was the electrotechnical industry for a long time. Currently, the range of using mica is quite wide. In this paper, attention is paid to the relatively promising areas of its use. The possibility of using composite materials based on mica as materials for protection against radioactive emissions and disposal of radioactive waste is considered. The object of the study: samples of a composite material based on mica, or the mikalexs. The method of recording ionizing radiation and the mass spectroscopic method were used to study linear coefficients of μ attenuation from gamma radiation of mikalexes on the basis of various micas after bombardment with 5 MeV, 10 MeV, 25 MeV electron beams. We used: a cesium source of γ-radiation with E = 0.661 MeV and a cobalt source with E = 1.25 MeV. Research results on the μ linear attenuation coefficients on γ-radiation of mikalexes based on various micas after their bombardment with electron fluxes showed that electron bombardment increases the penetrating power of gamma radiation in the mikalex. The dependence of the coefficient of linear attenuation on the type of mica used was determined. A new field of use of composite materials based on mica (micalex) for radiation protection and the disposal of radiation waste and their use in ultrahigh vacuum.

Optical chemical sensor for solving leak detection problems
Authors: Maslennikov Aleksandr , Zubkov Ilya , Pautov V.
Published: October 2018

The main features of the construction of gas analytical leak detection systems are noted, from the point of view of the sensitive element and the test substance (gas) used in the leak tightness control. It is shown that when checking the tightness of functioning systems, the standard leak detection equipment is of little use because it is impossible, in most cases, to use the specific test gases necessary for its operation. The use of solid-state gas analytical sensors for the construction of leak detection systems for operating process equipment is proposed. It is shown that one of the most suitable is the optical chemical sensor because of its low sensitivity to the humidity of the carrier gas, which, in such a process of leak detection, is atmospheric air. The properties of the proposed sensor are investigated, which are most important when used in leak detection systems. These parameters are the dynamic characteristics of the sensor, which are determined depending on the operating temperature and pressure of the sensor. The obtained data showed the prospects of using the investigated sensor and also allowed to outline ways of improving and optimizing its design.

Published: October 2018

The study is devoted to the objects of unfinished construction (hereinafter - UCO). The problem of the UCOs is urgent both for the regions and for the Russian Federation as a whole. The main reasons for the large number of the unfinished construction objects are analyzed in the paper. The global experience of solving the issue of long-term construction is considered. The unfinished objects spoil the architectural outlook of the city, while the lands are used inefficiently and the necrosis of capital occurs. In Russia, as a rule, conservation of these objects is not done that creates a real threat to life and health of people. The state and society cannot count on the economic effect of these objects, and they do not justify the goals and the means invested in them. Based on the conclusions drawn, measures are proposed that will allow preventing the suspension of the objects under construction at the moment, and complete the construction of the objects that begun earlier.

Acceleration of the cycle of extended reproduction of the active part of fixed assets in construction
Authors: Alekseeva Tatyana
Published: October 2018

One of the main reasons hindering the scientific and technological development of construction and the national economy as a whole is the mismatch of the cycles of expanded reproduction of the active part of fixed assets in construction as the basic cycles of the development of construction. The renovation of the active part of the fixed assets of construction organizations in the conditions of shrinking the investment base of construction is very slow, and, as a result, there is no timely provision of construction work with the new high-performance construction equipment and vehicles. Financial leasing, as world experience shows, is an effective tool for updating the fixed assets of construction organizations, but its share is too small in the total volume of investments in the active part of fixed assets in construction. There is a need to develop new mechanisms that would ensure synchronization of the basic cycles of development in construction and contribute to the development of leasing technologies in the construction sector. As a result of scientific research, a new mechanism for accelerating the cycles of expanded reproduction of the active part of the fixed assets in construction was developed. It is titled “innovative leasing engineering,” which allows to synchronize them with construction and investment cycles, contributes to increasing the volume of financial leasing in construction, and also provides timely support and capacity of strengthening the innovation wave in construction, eventually contributing to the accelerated transition of the investment and construction complex, as well as the national economy as a whole, to a new technological order.

Authors: Kankhva Vadim
Published: October 2018

The purpose of this article is to expand knowledge about qualitative and quantitative criteria for assessing investment risks and the properties of investment processes from the point of view of presenting real dynamic processes of investment exchange in the target information space. The method of the entropy of cover is the main method that is considered in the article when analyzing and managing risks. The paper suggests the grouping of the main risks in accordance with classification criteria and management levels, since the ranking of risks is associated with certain types of investments. Also, the article considers the main provisions using the information measure - the entropy of cover, which allow leading to the search for optimal information management of investment risk. The proposed methodology has sufficient flexibility, and it can be used to solve a variety of problems in the analysis of investment projects. It does not require a global restructuring of the financial management system, allows attracting resources already available and is an effective tool in the struggle against uncertainty.

Authors: Sobol Alexander , Fadeev Oleg
Published: October 2018

The article discusses the formation of the system of risk management and evaluation of the effectiveness of integrated project risk management in the space rocket sector. The classification of the integrated project risks for knowledge-based enterprise in the space rocket sector and credit institution was made. The main methods of project risks evaluation, which can be applied in the space rocket sector, are described. The scheme of integrated project risk management was made on the basis of the life cycle approach when implementing projects in the space rocket sector. When implementing project risks in the space rocket sector, an enlarged scheme of the Regulations on Integrated Project Risk Management System, was developed. An issue of integrated risk management in the space rocket sector using a system of measures being named the “Value-at-Risk” (VaR) was reviewed. It was concluded that there was a need for project implementation in the space rocket sector using a complex, effective, and integrated system of risk management.

Published: October 2018

The authors consider the problem of gender inequality in wages, which exists in Russia and throughout the world. A gender-sensitive budget is one way of overcoming gender inequality. The authors study the local budgets of two municipal organizations in the city of Novosibirsk, the local police and the local school, and analyze whether there is gender inequality in wages. They then provide an internal policy on ensuring equal pay for work of equal complexity, which can be used as a guide in state (budgetary) organizations in Russia when drawing up and executing their budgets.
Towards combining the innovation ecosystem concept with intermediary approach to regional innovation development
Authors: Gamidullaeva Leyla
Published: October 2018

Research and development is becoming a global phenomenon implemented on a purely collaborative basis. This leads to the need to search for partners, resources and ideas outside the company. Active development of information and digital technologies in the international practice has promoted gradual emergence of new forms of innovation intermediaries, which have not yet been applied in Russia. We suppose these new forms could be successfully implemented into the Russian innovation ecosystem. The present research is devoted to searching ways to unite the innovation ecosystem concept with the theory of innovation intermediation, emphasizing specific types of innovation intermediation and fundamental mechanisms thereof, supporting incentives and the role in an innovation ecosystem. The research results may be implemented into managerial practices in order to improve and increase the innovation feature and competitiveness of regional innovation systems of the Russian Federation and of concrete enterprises in particular.
High-resolution Distributed ISAR Imaging based on Sparse Representation
Authors: Li Yuanyuan , Fu Yaowen , Zhang Wenpeng
Published: October 2018

Distributed ISAR technique has the potential to increase the cross-range resolution by exploiting multi-channel echoes from distributed virtual equivalent sensors. In the existing imaging approaches, the echoes acquired from different sensors are rearranged into an equivalent single-channel ISAR signal. Then, the missing data between the observation angles of any two adjacent sensors is restored by interpolation. However, the interpolation method can be very inaccurate when the gap is large or the signal-to-noise (SNR) of echoes is low. In this paper, we discuss sparse representation of distributed ISAR echoes since the scattering field of the target is usually composed of only a limited number of strong scattering centres, representing strong spatial sparsity. Then, by using sparse algorithm (Orthogonal Matching Pursuit algorithm, OMP), the positions and amplitudes of the scattering points in every range bin can be recovered and the final ISAR image with high cross-range resolution can be obtained. Results show the effectiveness of the proposed method.
Initial Alignment of Large Azimuth Misalignment Angle in SINS based on Reduced Multiple Fading Factors Strong Tracking CKF

Published: October 2018

Aiming at the problem that Cubature Kalman Filter(CKF) has low accuracy and robustness under the condition of strapdown inertial navigation system(SINS) initial alignment due to model error and external disturbance, Reduced Multiple Strong Tracking Cubature Kalman Filter(RMSTCKF) is proposed, and the algorithm flow and sub-optimal solution of multiple fading factor are derived. Multiple fading factor can improve tracking ability under each state according to the degree of uncertainty of different states, having stronger adaptability and robustness. Applying RMSTCKF to large azimuth misalignment angle error function described by Euler platform error angle(EPEA), carrying out the simulation under two different conditions, namely noise mismatch and the base is disturbed, and making contrast between RSTCKF and RCKF, the simulation results show that the filter accuracy and convergence rate of RMSTCK when system noise mismatches with true noise are obviously better than RSTCKF and RCKF, having better practical value in engineering.

Using Neuroimaging to Detect Covert Awareness and Determine Prognosis of Comatose Patients: Informing Surrogate Decision Makers of Individual Patient Results
Authors: Graham Mackenzie , Doherty Colin , Naci Lorina
Published: October 2018

Robust prognostic indicators of neurological recovery are urgently needed for acutely comatose patients. Functional neuroimaging is a highly sensitive tool for uncovering covert cognition and awareness in behaviorally nonresponsive patients with prolonged disorders of consciousness, and may be applicable to acutely comatose patients. Establishing a link between early detection of covert awareness in acutely comatose patients and eventual recovery of function could have significant implications for patient prognosis, treatment, and end-of-life decisions. Because functional neuroimaging of acutely comatose patients is currently limited to the research context, ethical guidelines for disseminating a patient's individual research results to clinical teams and surrogate decision makers are needed. We propose an ethical framework composed of four conditions that can guide ethical disclosure of individual results of neuroimaging research in the acute care context.
