Deriving the Stellar Labels of LAMOST Spectra with the Stellar LAbel Machine (SLAM)
Authors: Zhang Bo , Liu Chao , Deng Li-Cai 
Published: January 2020

Abstract
The LAMOST survey has provided 9 million spectra in its Data Release 5 (DR5) at R ∼ 1800. Extracting precise stellar labels is crucial for such a large sample. In this paper, we report the implementation of the Stellar LAbel Machine (SLAM), which is a data-driven method based on support vector regression (SVR), a robust nonlinear regression technique. Thanks to the capability to model highly nonlinear problems with SVR, SLAM can generally derive stellar labels over a wide range of spectral types. This gives it a unique capability compared to other popular data-driven methods. To illustrate this capability, we test the performance of SLAM on stars ranging from T
eff ∼ 4000 to ∼8000 K trained on LAMOST spectra and stellar labels. At g-band signal-to-noise ratio (S/N
g
) higher than 100, the random uncertainties of T
eff, log g, and [Fe/H] are 50 K, 0.09 dex, and 0.07 dex, respectively. We then set up another SLAM model trained by APOGEE and LAMOST common stars to demonstrate its capability of dealing with high dimensional problems. The spectra are from LAMOST DR5 and the stellar labels of the training set are from APOGEE DR15, including T
eff, log g, [M/H], [α/M], [C/M], and [N/M]. The cross-validated scatters at

are 49 K, 0.10 dex, 0.037 dex, 0.026 dex, 0.058 dex, and 0.106 dex for these parameters, respectively. This performance is at the same level as other up-to-date data-driven models. As a byproduct, we also provide the latest catalog of ∼1 million LAMOST DR5 K giant stars with SLAM-predicted stellar labels in this work.
Nonlinear Convergence of Solar-like Stars Chromospheres Using Millimeter, Submillimeter, and Infrared Observations
Authors: Tapia-Vázquez F. , De la Luz V. 
Published: January 2020

Abstract
In this work, we present a new methodology to fit the observed and synthetic spectrum of solar-like stars at millimeter, submillimeter, and infrared wavelengths through semiempirical models of the solar chromosphere. We use the Levenberg–Marquardt algorithm as a Nonlinear method, PakalMPI as the semiempirical model of the solar chromosphere, and recent observations from the Atacama Large Millimeter/submillimeter Array of Alpha Centauri A as a test case. Our results show that we can use solar chromospheric semiempirical models as an input model to reproduce the observed spectrum of solar-like stars. The new profiles show similarities to the solar chromosphere as a minimum of temperature (without the restriction from CO emission) and a plateau in the high chromosphere. Our method provides a new fast numerical tool to estimate the physical conditions of solar-like stars.
Migration intentions of graduate students of medical universities in Russia and some CIS countries
Authors: Oksinenko Valeriia G. 
Published: January 2020

AbstractThe shortage of young medical workers in Russia is a long-standing and acute problem; its solution, even in part, is impossible without taking into account a whole set of factors. An empirical analysis of the results of the survey of graduates of medical and non-medical specializations in Russia and CIS countries gives grounds to identify graduates of medical faculties as a homogeneous group, which has similar migration patterns and relatively low variance in the impact of various factors on these patterns. When making decision about migration for employment graduates of medical specialties are less susceptible to the imbalance in the development of regions of Russia, but more sensitive to social factors. The findings of the paper confirm the importance of ongoing efforts in the field of social and economic policy keeping in mind its potential effectiveness to retain medical workers in regions of Russia.
The Cemented Femoral Stem: Selecting the Ideal Patient
Authors: Spitzer Andrew I 
Published: January 2020

abstract
A woman who is elderly, lightweight, and low demand has traditionally been considered an ideal candidate for a cemented femoral stem, ffetients who are young, heavy, and high demand have been considered higher risk for failure and, therefore, better suited for cementless femoral stems. However, modern cement techniques and implants have improved outcomes in high-risk cohorts, and stress shielding, thigh pain, and osteolysis have emerged as long-term challenges for cementless femoral stems. Recently reported positive bone remodeling around a cemented, triple-tapered, polished, collarless stem behaving according to the taper-slip philosophy of femoral stem fixation may widen the traditional indications for cemented femoral stems. Paradoxically, patiente initially thought to be poor candidates for cemented fixation may benefit most from the long-term bone preservation and positive loading characteristics of this new generation of cemented stem technology.
Frequent plateletpheresis donations & its effect on haematological parameters
Authors: Nayak Sweta , Coshic Poonam , Pandey R.M. , Chatterjee Kabita 
Published: January 2020

Background & objectives:
The well-being of donors undergoing frequent plateletpheresis has been a matter of concern. The aim of this study was to analyze the effect of frequent plateletpheresis on the haematological parameters (HP) of repeat donors.

Methods:
The study was conducted during February 2016 to March 2017 on all the repeat plateletpheresis donors undergoing the 2nd plateletpheresis within a month of the first in a tertiary care centre. Donors repeating plateletpheresis 3rd and 4th times were also studied. The values of the HP observed on follow up after plateletpheresis done on three different separators were compared.

Results:
HPs of the 98 donors were similar at follow up except mean platelet volume (P<0.05). Of the 98 donors, 35 were followed up within a week and 63 were followed up within 8-30 days. No significant alteration was found in the HPs except a significant difference in the variation of platelet counts of the two groups (P=0.025). In 34 donors who presented 3rd time for plateletpheresis (mean gap between 1st and 3rd plateletpheresis=31 days), no significant differences in the HPs were found except the platelet distribution width (P<0.05). Minimal difference in the HP was found in the baseline and the follow up of 3rd plateletpheresis i.e., at 4th plateletpheresis donation. Plateletpheresis through all the three cell separators used had similar effects on the follow up HPs.

Interpretation & conclusions:
Repeated plateletpheresis can be done without any detrimental effects on the cell counts of the plateletpheresis donors. The three cell separators yielded similar post-donation follow up haematological parameters.
Assessing the susceptibility of highly pathogenic avian influenza H5N1 viruses to oseltamivir using embryonated chicken eggs
Authors: Tare Deeksha S. , Kode Sadhana S. , Hurt Aeron C. , Pawar Shailesh D. 
Published: January 2020

Background & objectives:
The susceptibility of influenza viruses to neuraminidase inhibitors (NAIs) is studied using enzyme-based assays, sequence analysis and in vitro and in vivo studies. Oseltamivir carboxylate (OC) is the active prodrug of the NAI oseltamivir. There is lack of information on the use of embryonated chicken eggs for studying susceptibility of highly pathogenic avian influenza (HPAI) H5N1 viruses to antiviral drugs. The aim of the present study was to assess the use of 10 day old embryonated chicken eggs for studying antiviral susceptibility of HPAI H5N1 viruses.

Methods:
Two HPAI H5N1 viruses isolated from India were used in the study. Fluorescence-based NAI assay was performed to determine antiviral susceptibility of these viruses. In ovo antiviral assays were carried out using 10 day old embryonated chicken eggs. The virus dilutions were incubated with 14 μg/ml of OC and inoculated in the allantoic cavity. In the eggs, 50 per cent egg infectious dose (EID50) titres as well as mortality were quantitated.

Results:
The two viruses used were susceptible to OC in the NAI assay. It was found that there was a significant drop in EID50 titres; however, no significant protection from mortality after OC treatment was observed.

Interpretation & conclusions:
By measuring viral titres, the egg model was suitable to study the susceptibility of HPAI viruses to antiviral drugs along with NAI assay. The present study highlights the use of eggs as a model to study susceptibility of HPAI viruses to OC.
Is it necessary to focus on morphologically normal acrosome of sperm during intracytoplasmic sperm injection?
Authors: Zahiri Ziba , Ghasemian Fatemeh 
Published: January 2020

Background & objectives:
The detailed assessment of sperm morphology is important in the semen of infertile men because there is a low proportion of normal spermatozoa. One of the parameters of such sperm morphology is the acrosome, and its effect on assisted reproductive outcomes is controversial. This study was undertaken to evaluate the association between different forms of acrosome on the chromatin status and the assisted reproductive outcomes.

Methods:
A total of 1587 unstained sperms from 514 infertile men were captured and analyzed for different acrosome forms (normal, large, small, skew, amorphous acrosome and without acrosome) in real time during intracytoplasmic sperm injection into oocytes. The association between the percentage of sperms with atypical acrosome and head shapes and the sperm chromatin status was studied. Fertilization, zygote and embryo quality and clinical pregnancy rates were calculated for different groups of sperms.

Results:
The highest frequency of irregular shapes of acrosomes, such as small, large and amorphous, was observed in abnormal ellipticity, anteroposterior symmetry and angularity parameters, respectively (P<0.05). The fertilization rate of injected sperms with large (P<0.01) and small (P=0.001) acrosomes and without acrosome (P=0.001) was significantly lower in comparison with normal acrosomes. The quality of zygotes (Z3, P=0.05), embryos (grade C, P<0.05) and the pregnancy rate (P=0.001) from injected sperms with large acrosomes were significantly lower compared with normal acrosomes.

Interpretation & conclusions:
Our findings showed that the different sperm acrosome morphologies (e.g., large, small, and without acrosome) might negatively relate with chromatin integrity and decrease the sperm's fertility potential and pregnancy rate during intracytoplasmic sperm injection (ICSI) cycles.
Very high stratospheric influence observed in the free troposphere over the northern Alps – just a local phenomenon?
Authors: Trickl Thomas , Vogelmann Hannes , Ries Ludwig , Sprenger Michael 
Published: January 2020

Abstract. The atmospheric composition is strongly influenced by a
change in atmospheric dynamics, which is potentially related to climate
change. A prominent example is the doubling of the stratospheric ozone
component at the Zugspitze summit station (2962 m a.s.l.,
Garmisch-Partenkirchen, Germany) between the mid-seventies and 2005, roughly
from 11 to 23 ppb (43 %). Systematic efforts for identifying and
quantifying this influence have been made since the late 1990s. Meanwhile,
routine lidar measurements of ozone and water vapour carried out at
Garmisch-Partenkirchen (German Alps) since 2007, combined with in situ and
radiosonde data and trajectory calculations, have revealed that
stratospheric intrusion layers are present on 84 % of the yearly
measurement days. At Alpine summit stations the frequency of intrusions
exhibits a seasonal cycle with a pronounced summer minimum that is
reproduced by the lidar measurements. The summer minimum disappears if one
looks at the free troposphere as a whole. The mid- and upper-tropospheric
intrusion layers seem to be dominated by very long descent on up to
hemispheric scale in an altitude range starting at about 4.5 km a.s.l.
Without interfering air flows, these layers remain very dry, typically with
RH ≤5 % at the centre of the intrusion. Pronounced ozone
maxima observed above Garmisch-Partenkirchen have been mostly related to a
stratospheric origin rather than to long-range transport from remote
boundary layers. Our findings and results for other latitudes seem to
support the idea of a rather high contribution of ozone import from the
stratosphere to tropospheric ozone.
Cloud_cci Advanced Very High Resolution Radiometer post meridiem (AVHRR-PM) dataset version 3: 35-year climatology of global cloud and radiation properties
Authors: Stengel Martin , Stapelberg Stefan , Sus Oliver , Finkensieper Stephan , Würzler Benjamin , Philipp Daniel , Hollmann Rainer , Poulsen Caroline , Christensen Matthew , McGarragh Gregory 
Published: January 2020

Abstract. We present version 3 of the Cloud_cci Advanced Very High Resolution Radiometer post meridiem (AVHRR-PM) dataset, which contains a comprehensive set of cloud and radiative flux properties on a global scale covering the period of 1982 to 2016. The properties were retrieved from AVHRR measurements recorded by the afternoon (post meridiem – PM) satellites of the National Oceanic and Atmospheric Administration (NOAA) Polar Operational Environmental Satellite (POES) missions. The cloud properties in version 3 are of improved quality compared with the precursor dataset version 2, providing better global quality scores for cloud detection, cloud phase and ice water path based on validation results against A-Train sensors.
Furthermore, the parameter set was extended by a suite of broadband radiative flux properties. They were calculated by combining the retrieved cloud properties with thermodynamic profiles from reanalysis and surface properties. The flux properties comprise upwelling and downwelling and shortwave and longwave broadband fluxes at the surface (bottom of atmosphere – BOA) and top of atmosphere (TOA). All fluxes were determined at the AVHRR pixel level for all-sky and clear-sky conditions, which will particularly facilitate the assessment of the cloud radiative effect at the BOA and TOA in future studies. Validation of the BOA downwelling fluxes against the Baseline Surface Radiation Network (BSRN) shows a very good agreement. This is supported by comparisons of multi-annual mean maps with NASA's Clouds and the Earth's Radiant Energy System (CERES) products for all fluxes at the BOA and TOA. The Cloud_cci AVHRR-PM version 3 (Cloud_cci AVHRR-PMv3) dataset allows for a large variety of climate applications that build on cloud properties, radiative flux properties and/or the link between them. For the presented Cloud_cci AVHRR-PMv3 dataset a digital object identifier has been issued: https://doi.org/10.5676/DWD/ESA_Cloud_cci/AVHRR-PM/V003 (Stengel et al., 2019).
Seasonal variation of the principal tidal constituents in the Bohai Sea
Authors: Wang Daosheng , Pan Haidong , Jin Guangzhen , Lv Xianqing 
Published: January 2020

Abstract. The seasonal variation of tides plays a significant role
in water level changes in coastal regions. In this study, seasonal
variations of four principal tidal constituents, M2, S2, K1,
and O1, in the Bohai Sea, China, were studied by applying an enhanced
harmonic analysis method to two time series: 1-year sea level observations
at a mooring station (named E2) located in the western Bohai Sea and 17-year
sea level observations at Dalian. At E2, the M2 amplitude and phase lag
have annual frequencies, with large values in summer and small values in
winter, while the frequencies of S2 and K1 amplitudes are also
nearly annual. In contrast, the O1 amplitude increases constantly from
winter to autumn. The maxima of phase lags appear twice in 1 year for
S2, K1, and O1, taking place near winter and summer. The
seasonal variation trends estimated by the enhanced harmonic analysis at
Dalian are different from those at E2, except for the M2 phase lag. The
M2 and S2 amplitudes show semi-annual and annual cycles,
respectively, which are relatively significant at Dalian. The results of
numerical experiments indicate that the seasonality of vertical eddy
viscosity induces seasonal variations of the principal tidal constituents at
E2. However, the tested mechanisms, including seasonally varying
stratification, vertical eddy viscosity, and mean sea level, do not
adequately explain the observed seasonal variations of tidal constituents at
Dalian.
Controversies and consensus in research on dialogic teaching and learning
Authors: Asterhan Christa S. C. , Howe Christine , Lefstein Adam , Matusov Eugene , Reznitskaya Alina 
Published: January 2020

Scholarly interest in dialogic pedagogy and classroom dialogue is multi-disciplinary and draws on a variety of theoretical frameworks. On the positive side, this has produced a rich and varied body of research and evidence. However, in spite of a common interest in educational dialogue and learning through dialogue, cross-disciplinary engagement with each other’s work is rare. Scholarly discussions and publications tend to be clustered in separate communities, each characterized by a particular type of research questions, aspects of dialogue they focus on, type of evidence they bring to bear, and ways in which standards for rigor are constructed. In the present contribution, we asked four leading scholars from different research traditions to react to four provocative statements that were deliberately designed to reveal areas of consensus and disagreement[1]. Topic-wise, the provocations related to theoretical foundations, methodological assumptions, the role of teachers, and issues of inclusion and social class, respectively. We hope that these contributions will stimulate cross- and trans-disciplinary discussions about dialogic pedagogy research and theory.[1] The authors of this article are five scholars, the dialogic provocateur and the four respondents. The order of appearance of the authors was determined alphabetically.

Burnout, Perceived Stress, Sleep Quality, and Smartphone Use: A Survey of Osteopathic Medical Students
Authors: Brubaker Jennifer R. , Beverly Elizabeth A. 
Published: January 2020

AbstractContextBurnout is a psychological syndrome that results from prolonged exposure to stressful work activities and includes 3 dimensions: emotional exhaustion (EE), depersonalization (DP), and low sense of personal accomplishment (PA). Burnout is a widespread problem in numerous professions but is particularly high among medical students, residents, and early-career physicians compared with college graduates of similar age. However, minimal research has addressed burnout in osteopathic medical students.ObjectiveTo assess levels of burnout in osteopathic medical students and to examine the relationship among burnout, perceived stress, sleep quality, and smartphone use.MethodsThis study used a cross-sectional study design and an anonymous, electronic questionnaire service to administer the Maslach Burnout Inventory, the Perceived Stress Scale-4, the Pittsburgh Sleep Quality index, and the Smartphone Addiction Scale Short Version.ResultsA total of 385 participants (mean [SD] age, 25 [2.4] years; 208 [54.0%] women; 286 [74.3%] white; 138 [35.8%] second-year osteopathic medical students [OMSs]) completed the survey. Of the 385 participants, 9 (2.3%) reported high EE, 67 (17.4) reported high DP, and 310 (80.5) reported a high level of low PA. When comparing dimensions of burnout by gender, only levels of PA differed by gender, with men reporting higher levels of burnout compared with women (χ12=5.2,P=.022). Further, levels of DP differed by year in medical school (χ2=17.3,P=.008), with post-hoc comparisons showing differences between OMS I and OMS III (F=4.530,df=3,P=.004). Linear regression models showed that higher perceived stress (standardized β=0.5,P<.001), poorer sleep quality (standardized β=0.2,P=.001), and higher smartphone addiction scores (standardized β=0.1,P<.001) were associated with higher EE. Similarly, higher perceived stress (standardized β=0.2,P<.001), poorer sleep quality (standardized β=0.2,P=.001), and higher smartphone addiction scores (standardized β=0.2,P=.001) were associated with higher DP. Only higher perceived stress was associated with higher levels of low PA (standardized β=−0.4,P<.001).ConclusionsThese findings suggest independent associations with EE, DP, perceived stress, sleep quality, and smartphone use. Additional research with a larger, more diverse sample is needed to confirm these findings. If confirmed, wellness interventions can be designed to target 2 modifiable factors: sleep quality and smartphone use.
Taxonomy of the Lateral Strain Patterns at the Sphenobasilar Synchondrosis for Osteopathic Cranial Manipulative Medicine
Authors: Capobianco John D. , Shermon Suzanna 
Published: January 2020

Abstract
Lateral strain is a type of nonphysiologic cranial dysfunction that occurs at the sphenobasilar synchondrosis. In this dysfunction, the sphenoid and occiput rotate in the same directions along 2 vertical axes. There is currently no consensus on the nomenclature for this cranial dysfunction. In this article, the authors provide a standard nomenclature for lateral strains using the historical writings of pioneers in osteopathic medicine, including William Gardner Sutherland, DO, Anne L. Wales, DO, and Harold Magoun, DO. The authors establish the following consensus: (1) Lateral strains are named for the side to which the basisphenoid shifts; (2) The more prominent greater wing of the sphenoid is on the same side to which the basisphenoid shifts; (3) In vault and fronto-occipital holds, the holds form a parallelogram shape, with the index fingers pointing to the same side as the more prominent greater wing; and (4) The hand that is on the side of the prominent greater wing will shift anteriorly while the hand on the opposite side will shift posteriorly.
