AbstractThis article aims to evaluate the impact of a mentorship program to enhance the training of clinical and research scientists in obstetrics and gynecology (OBGYN). A departmental course was developed for junior faculty and fellows based on their areas of interest. The research was IRB-approved. The curriculum consisted of monthly interactive workshops for an interdisciplinary group of trainees in OBGYN. Themes included research, education, and leadership in academic OBGYN. There was a strong emphasis on participatory exercises. Examples of curriculum topics included manuscript publication and review, grant writing, working with an IRB, promotion, and time management. Pre- and post-course questionnaires assessed participants' confidence in skills related to the course topics. Generalized linear models were used to assess changes in post-course response, using each question as the dependent variable and an indicator for post-course as the predictor variable. The control group was composed of junior faculty and fellows before the course was initiated. Outcome measures included the number and impact factor of published manuscripts. A Wilcoxon rank-sum test was used to assess outcome measures. Of the 118 attendees, 26 (22.0%) were junior faculty, 35 (29.66%) were clinical fellows, and 28 (23.7%) were research fellows, other research staff, or students. For each 3-year course series, an average of 20 participants completed the post-course surveys, of which 72% were clinical fellows, 22% were assistant professors, and 5% were instructors. The data revealed a statistically significant change in the participant's overall confidence in skills related to research, education, and leadership when comparing the cumulative results from the pre-to-post course surveys (p < 0.001). Specifically, participants noted improved confidence in their skills related to clinical and translation research (p < 0.001) and leadership and academic career advancement (p = 0.001). Additionally, junior faculty and clinical fellows who attended the course had a higher number of publications during the course period compared with controls (p = 0.003 and p = 0.008, respectively). This subspecialty-tailored, departmental training program was effective in increasing junior faculty and clinical fellows' confidence in skills related to career advancement and research and in the number of peer-reviewed publications.
Analysis of the light shift in the hyper-Ramsey scheme of two-level atom interrogation in an optically dense medium
Authors: Barantsev K.A. , Litvinov A.N. 
Published: September 2019

Abstract
The properties of the Ramsey resonance and its sensitivity to the light shift of the atomic transition frequency are investigated in the case of the hyper-Ramsey interrogation in an optically dense medium of cold atoms. The shape of the interrogating pulses varies significantly due to the processes of absorption and dispersion in the atomic medium, which leads to a distortion of the Ramsey resonance and a periodic change in the central minimum to the maximum and vice versa. The dependence of the position of the central resonance on the light shift of the atomic transition is found with the attenuation of radiation in the medium taken into account. It is shown that in a certain section of the medium this dependence becomes N-shaped.
Tetrafluoroethylene as a fuel component for an atomic fluorine generator of a supersonic continuous-wave chemical HF laser
Authors: Fedorov I.A. 
Published: September 2019

Abstract
A cheap and widely accessible combination (one of non-saturated perfluorocarbons), i.e. C2F4 tetrafluoroethylene, is proposed as an alternative fuel component for an atomic fluorine generator of a supersonic cw chemical HF laser of self-contained type. Combustion products of the hypergolic F2 – C2F4 – He mixture do not contain active relaxants of vibrationally excited HF(v) molecules. According to estimates, the atomic fluorine yield under comparable conditions is about 70 % in relation to that of the atomic fluorine generator operating on the F2 – D2 – He mixture which is the ‘basic’ one for a HF laser. The specific power is reduced by 23 % with an improvement in a set of the fuel performance and a significant reduction in the cost of triggering the laser in the course of its bench tests.

Published: September 2019

Abstract
Comparative experimental study of superluminescent diodes (SLDs) with active layers containing one, two, or three 5.0-nm-wide quantum wells symmetrically positioned in the waveguide layer is performed. It is shown that an increase in the number of quantum wells leads to narrowing of the superluminescence spectrum and weakens the dependence of its width on the pump level. Simultaneously, the degree of polarisation of the output radiation noticeably increases. For example, rather reliable high-power narrow-band SLDs with a spectral halfwidth smaller than 8 nm and polarisation ratio TE/TM exceeding 20 dB are developed.
Cluster-based topological features of nodes in a multiplex network—from a network of networks perspective

Published: September 2019

Abstract
In the gathered multiplex systems, nodes inherit a part of their original system’s topological features, as in the world economic system, national policies and resource distribution bring industry advantages and resource advantages to the domestic industry. Although they represent one of the important original topological features of nodes, the inherited topological features of nodes have not received sufficient attention and have hardly been analyzed by existing network models. In our research, we defined the inherited topological features of nodes as ‘cluster-based topological features. To accurately calculate the cluster-based topological features of nodes in multiplex networks, we first provide a network model to summarize the multiplex networks into a calculable network of networks (NoN). Based on our network model, we propose a series of algorithms for calculating industries’ cluster-based topological features. Our calculating process contains 2 steps: ‘abstracting’ the NoN into one-layer calculable network; ‘inheriting’ subnetworks’ topological features into the inner nodes. Our network model and calculation algorithms are applied in a series of theoretical and empirical multiplex networks. The results not only confirm the realizability of our model but also produce several interesting findings, the most important of which is that some unremarkable nodes in multiplex network may have a very high contributory value from NoN perspective.

Abstract
Recent experimental and theoretical work on hydrogen-like absorption spectra of excitons in external magnetic fields revealed new effects when the Coulomb interaction becomes comparable to the magnetic perturbation. We present a theoretical approach that allows for calculation of absorption spectra for any value of magnetic field. This approach opens the possibility to compute the optical functions i.e. reflectivity, transmission and absorption including the excitonic effects for various strength of external magnetic field.
Isotope-geochronological (SHRIMP-RG) studies of zircon from muscovite-tourmaline granites of the Kolmozero-Voronya greenstone belt: insights for sources of rare metal pegmatites
Authors: Kudryashov N M , Udoratina O V , Coble M A 
Published: September 2019

Abstract
The article provides data on the U-Pb isotope (SHRIMP RG) study of tourmaline-muscovite granites of the Kolmozero-Voronya greenstone belt. The tourmaline-muscovite granites formed in the time span of 2451±60 Ma, which corresponds with the previously obtained age of tantalite from rare metal pegmatites of the Vasin-Myl’k deposit. The obtained age indicates the Paleoproterozoic formation stage of granites and, probably, associated rare metal pegmatites.

Abstract
The glasses were found in the tuffisites of Orto-Yiarginskoe field (Anabar region, Arctic Siberia). The composition of the glasses is comparable with the composition of the glasses from the Popigai impact structure and the gneisses of the Archean basement of the Anabar folded system. The age of the studied glasses is comparable with the age of the glasses of the Popigai impact structure. Mineralogical studies were carried out using scanning electron microscopy (MIRA 3 LMU, Tescan Ltd) with the INCA Energy 450+ XMax 80 microanalysis system (Oxford Instruments Ltd). The age of the glasses is determined by the 40Ar-39Ar method in the Collective Use Center of the IGM SB RAS.

Abstract
Parasitic Hymenoptera is important natural enemies to control pest population but threatened by habitat transformation. It is important to know the sustainable management agroecosystem that may conserve beneficial insects. There is still minimum research about the effect of riparian buffers effect on Hymenoptera diversity. The objectives of this research were to study parasitic Hymenoptera species richness and abundance in oil palm and rubber plantation, investigate the effect of riparian sites on diversity and species composition across the different habitat. The research was conducted in Jambi Province, Sumatra, Indonesia which consists of two different agroecosystems, oil palm, and rubber plantation. Parasitic Hymenoptera was collected by direct sampling using insect nets and traps using a yellow pan and malaise traps. Parasitic Hymenoptera species richness was different among oil palm and rubber plantation. Oil palm had higher species richness than rubber plantation. Riparian buffers sites, either oil palm or rubber plantation, had higher numbers of parasitic Hymenoptera species richness and abundance than upland dry sites. These results are related to the high number of wild flowering plants species richness in riparian buffers sites. Community structure between riparian and dry agroecosystem was not different. The same agroecosystem provided the same feeding source and host for parasitoid. Therefore, managing sustainable agroecosystem should consider the presence of wild flowering plants that may preserve parasitic Hymenoptera diversity in providing natural enemy services in an agroecosystem.

Published: September 2019

Abstract

Elaeidobius kamerunicus is a well-known insect pollinator of oil palm. The presence of E. kamerunicus directly creates sustainability in oil palm plantations and successfully increase palm oil production in Indonesia. However, recent reports showed that there are morphometric differences across islands that might be due to different selection pressures that might influence the genetic diversity of the weevil. The aim of this research is to study and analyze E. kamerunicus genetic diversity from various locations in Indonesia. Samples were taken using a purposive sampling method from post-anthesis male flowers from 16 regions oil palm centers in Indonesia. Insect DNA amplified by PCR technique using 11 SSR primer. The results showed that some of the SSR markers used were polymorphic. The highest percentage of polymorphic loci is the population of Central Kalimantan, West Java, and Papua. The Population of E. kamerunicus in Indonesia has a close relationship and most of the population does not result from inbreeding. Phylogenetic tree constructed using DARwin formed three groups containing mixtures of five spatial distribution regions (islands). The high PIC value and the formation groups indicate the high genetic diversity of E. kamerunicus in Indonesia.

Abstract
Doublecortin-like kinase 1 (DCLK1) promotes tumour proliferation in human colorectal cancer (CRC). To elucidate the mechanism and clinical relevance of this association, we performed expression analysis using commercially available colon carcinoma cell lines (SW480, HCT116, CaCO2, SW48 and SKCO1) and immunohistochemical analysis of 200 resected CRC samples for correlation with clinical features. DCLK1 showed a high level of expression, especially in SW480 and HCT116 cells. Silencing DCLK1 expression using short hairpin DCLK1 (shDCLK1) RNA inhibited the growth and invasion capacities of these cell lines, which showed signs of entering into the mesenchymal–epithelial transition (MET). We found evidence of a strong correlation of DCLK1 expression with that of Tribbles homolog 3 (TRIB3), and silencing TRIB3 also led to the MET phenotype in these cells. In the clinical samples, compared with samples showing low expression of DCLK1, high expression was associated with poor prognosis in terms of overall and recurrence-free survival (P &lt; 0.0001). The results of univariate and multivariate analysis suggested that high expression of DCLK1 in clinical colon cancer samples was tied to poor prognosis, cancer invasion depth and lymph node metastasis. DCLK1 expression correlates with malignant grade of colon cancer and offers a potential treatment target.
Treatment for Early, Uncomplicated Coccidioidomycosis: What Is Success?

Published: September 2019

AbstractThe care of primary pulmonary coccidioidomycosis remains challenging. Such infections produce a variety of signs, symptoms, and serologic responses that cause morbidity in patients and concern in treating clinicians for the possibility of extrapulmonary dissemination. Illness may be due to ongoing fungal growth that produces acute inflammatory responses, resulting in tissue damage and necrosis, and for this, administering an antifungal drug may be of benefit. In contrast, convalescence may be prolonged by other immunologic reactions to infection, even after fungal replication has been arrested, and in those situations, antifungal therapy is unlikely to yield clinical improvement. In this presentation, we discuss what findings are clinical indicators of fungal growth and what other sequelae are not. Understanding these differences provides a rational management strategy for deciding when to continue, discontinue, or reinstitute antifungal treatments.

Published: September 2019

AbstractBackgroundThe Finnish government has emphasized the need to expedite educational transitions. We study if a late start of upper secondary education is related to health-related selection, namely health-compromising behaviours in adolescence.MethodsA large cohort of adolescents from the seventh (12–13 years) and ninth (15–16 years) grades answered online classroom surveys (total n = 10 873). They were followed to the start of upper secondary education, obtained from the Joint Application Registry. We compared those who continued studies directly from the ninth grade with later starters. We measured late bedtime, breakfast not every school day, tooth brushing less than twice-a-day, monthly alcohol consumption, weekly smoking, daily energy drinks, physical activity &lt;6 days/week and excessive screen time. Multilevel logistic regressions and latent class analyses were conducted.ResultsIn gender and school adjusted models in the seventh grade, all behaviours except physical activity predicted the late start. The strongest predictor was smoking, OR = 2.96 (CI = 2.25–3.89). In the ninth grade, smoking, breakfast, tooth brushing and energy drinks, OR = 1.80, (CI = 1.36–2.39, strongest), were predictive. After controlling for sociodemographic background and academic achievement, associations for alcohol and screen time became non-significant in the seventh grade. In the ninth grade, only screen time remained significant, OR = 1.33 (CI = 1.04–1.71). Health-compromising behaviours formed clusters. Belonging to the unhealthy cluster predicted the late start in both grades, in adjusted models only in the seventh grade.ConclusionsStudents with health-compromising behaviours are less likely to start upper secondary education directly after the compulsory education. This may increase the risk for fragmentary educational trajectories and work careers.
A teaching protocol demonstrating the use of EasyClone and CRISPR/Cas9 for metabolic engineering of Saccharomyces cerevisiae and Yarrowia lipolytica
Authors: Milne N , Tramontin L R R , Borodina I 
Published: September 2019

ABSTRACT
We present a teaching protocol suitable for demonstrating the use of EasyClone and CRISPR/Cas9 for metabolic engineering of industrially relevant yeasts Saccharomyces cerevisiae and Yarrowia lipolytica, using β-carotene production as a case study. The protocol details all steps required to generate DNA parts, transform and genotype yeast, and perform a phenotypic screen to determine β-carotene production. The protocol is intended to be used as an instruction manual for a two-week practical course aimed at M.Sc. and Ph.D. students. The protocol details all necessary steps for students to engineer yeast to produce β-carotene and serves as a practical introduction to the principles of metabolic engineering including the concepts of boosting native precursor supply and alleviating rate-limiting steps. It also highlights key differences in the metabolism and heterologous production capacity of two industrially relevant yeast species. The protocol is divided into daily experiments covering a two-week period and provides detailed instructions for every step meaning this protocol can be used ‘as is’ for a teaching course or as a case study for how yeast can be engineered to produce value-added molecules.

ABSTRACT
SIGNALS, the Star formation, Ionized Gas, and Nebular Abundances Legacy Survey, is a large observing programme designed to investigate massive star formation and H ii regions in a sample of local extended galaxies. The programme will use the imaging Fourier transform spectrograph SITELLE at the Canada–France–Hawaii Telescope. Over 355 h (54.7 nights) have been allocated beginning in fall 2018 for eight consecutive semesters. Once completed, SIGNALS will provide a statistically reliable laboratory to investigate massive star formation, including over 50 000 resolved H ii regions: the largest, most complete, and homogeneous data base of spectroscopically and spatially resolved extragalactic H ii regions ever assembled. For each field observed, three datacubes covering the spectral bands of the filters SN1 (363–386 nm), SN2 (482–513 nm), and SN3 (647–685 nm) are gathered. The spectral resolution selected for each spectral band is 1000, 1000, and 5000, respectively. As defined, the project sample will facilitate the study of small-scale nebular physics and many other phenomena linked to star formation at a mean spatial resolution of ∼20 pc. This survey also has considerable legacy value for additional topics, including planetary nebulae, diffuse ionized gas, and supernova remnants. The purpose of this paper is to present a general outlook of the survey, notably the observing strategy, galaxy sample, and science requirements.

ABSTRACT
We present the results of a 3-yr long, medium-resolution spectroscopic campaign aimed at identifying very metal-poor stars from candidates selected with the CaHK, metallicity-sensitive Pristine survey. The catalogue consists of a total of 1007 stars, and includes 146 rediscoveries of metal-poor stars already presented in previous surveys, 707 new very metal-poor stars with $\rm [Fe/H] \lt -2.0$, and 95 new extremely metal-poor stars with $\rm [Fe/H] \lt -3.0$. We provide a spectroscopic [Fe/H] for every star in the catalogue, and [C/Fe] measurements for a subset of the stars (10 per cent with $\rm [Fe/H] \lt -3$ and 24 per cent with $-3 \lt \rm [Fe/H] \lt -2$) for which a carbon determination is possible, contingent mainly on the carbon abundance, effective temperature and signal-to-noise ratio of the stellar spectra. We find an average carbon enhancement fraction ([C/Fe] ≥ +0.7) of 41 ± 4 per cent for stars with $-3 \lt \rm [Fe/H] \lt -2$ and 58 ± 14 per cent for stars with $\rm [Fe/H] \lt -3$, and report updated success rates for the Pristine survey of 56 per cent and 23 per cent to recover stars with $\rm [Fe/H] \lt -2.5$ and $\lt -3$, respectively. Finally, we discuss the current status of the survey and its preparation for providing targets to upcoming multi-object spectroscopic surveys such as William Herschel Telescope Enhanced Area Velocity Explorer.
