Fetal Heart Rate Patterns in Monochorionic Twins Following Acute Twin-Twin Transfusion
Background. We present here 2 cases of acute twin-twin transfusion occurred during vaginal labor in monochorionic-diamniotic twin pregnancies. Case. Fetal heart rate tracings showed tachycardia in the donor twin in the first case, while they showed reassuring patterns in both twins in the second case. Conclusion. These differences in changes of fetal heart rate in the donor twins following acute twin-twin transfusion may be resulted from the differences in amount of transfusion and elapsed time

Recently, crime and delinquency have been changing during adolescence.It is suggested that an obscurity of reality and fiction in the present advanced information society and a feeling of emptiness from anxiety of uneasiness are causes.Nevertheless, there has never been an empirical study providing evidence towards those claims.
This study indicates the relation of socially delinquent and emptiness among college students.The socially delinquent was suggested to concerns attitudes of disvalue to the socially delinquent and cognitive distorted(Yoshizawa & Yoshida,2004).Thus,this study tested the relationships between emptiness,cognitive distortion,and social delinquency.
Consequently,the suggested model was different in men and women.In men, a direct effect towards apathy and an indirect effect of cognitive distortion to the socially delinquent were found.In addition,a mediating effect of egocentricity of cognitive distortion mediating the association between emptiness from anxiety of uneasiness and the socially delinquent was indicated.In women,a direct effect towards an emptiness from an anxiety of uneasiness to social delinquency and a mediating effect towards a denigrating fallaciousness of cognitive distortion mediating the association between loneliness of emptiness and socially delinquent was indicated
Cosmic Galaxy-IGM HI Relation at Probed in the COSMOS/UltraVISTA deg Field
We present spatial correlations of galaxies and IGM HI in the
COSMOS/UltraVISTA 1.62 deg field. Our data consist of 13,415 photo-
galaxies at with and the Ly forest absorptions in
the background quasar spectra selected from SDSS data with no signature of
damped Ly system contamination. We estimate a galaxy overdensity
in an impact parameter of 2.5 pMpc, and calculate the Ly
forest fluctuations whose negative values
correspond to the strong Ly forest absorptions. We identify weak
evidence of an anti-correlation between and with a Spearman's rank correlation coefficient of suggesting
that the galaxy overdensities and the Ly forest absorptions positively
correlate in space at the confidence level. This positive
correlation indicates that high- galaxies exist around an excess of HI gas
in the Ly forest. We find four cosmic volumes, dubbed
-, that have extremely large (small) values of () and (), three
out of which, -, significantly depart from the correlation,
and weaken the correlation signal. We perform cosmological hydrodynamical
simulations, and compare with our observational results. Our simulations
reproduce the correlation, agreeing with the observational results. Moreover,
our simulations have model counterparts of -, and suggest
that the observations pinpoint, by chance, a galaxy overdensity like a
proto-cluster, gas filaments lying on the sightline, a large void, and
orthogonal low-density filaments. Our simulations indicate that the significant
departures of - are produced by the filamentary large-scale
structures and the observation sightline effects.Comment: 14 pages, 12 figures. Accepted for publication in Ap
Crystallinity of In-Ga-Zn-oxide (IGZO) in CAAC-IGZO vertical FET
Oxide semiconductor field-effect transistors (OSFETs) are actively developed [1]. In particular, there are many reports on a typical oxide semiconductor, In-Ga-Zn oxide (IGZO) [2]. An OSFET is fabricated with a planar structure in many cases; however, a vertical FET (VFET) with a current path perpendicular to a substrate can be fabricated with an area overhead comparable to one trench hole, and is gathering attention [3]. The VFET structure enables OSFETs to be highly integrated, and also allows the resolution of displays to be higher.

Usefulness of Non-Uniform Heating and Quenching Method for Residual Stress of Bimetallic Roll: FEM Simulation Considering Creep Behavior
Bimetallic rolls are widely used in steel rolling industries because of the excellent hardness, wear resistance and high temperature properties. Controlling the residual stress distribution is important to improve the roll fatigue life due to the compressive residual stress at the roll surface. Recently, to reduce the tensile residual stress appearing at the roll center, quenching heat treatment is performed just after heating the roll non-uniformly instead of heating the roll uniformly with enough time. In this paper, therefore, the residual stresses are compared after between the uniform heating quenching and the non-uniform heating quenching on the basis of the FEM simulation. The results show that tensile stresses at the roll center for non-uniform heating are smaller than that for uniform heating by 400MPa although the same compressive stresses appear at the surface. The effect of creep on stress relaxation is also considered in this study. By considering creep, the maximum tensile residual stress decreases by 8% for uniform heating and by 15% for non-uniform heating
Residual stress generation mechanism for hot strip composite rolls during quenching process
Composite rolls are widely used in hot rolling mill because of the excellent hardness, wear resistance and high temperature properties. During hot rolling process, composite rolls are subjected to heating-cooling thermal cycles from the hot strip contact and water cooling. The thermal stress is added to already existing residual stress. The thermal fatigue cracking appears at roll surface, and the fracture is possible happen in roll centre when the tensile stress exceeds the centre strength. Therefore, residual stress plays an important role in composite roll. In this paper, FEM (finite element method) simulation is performed to investigate the generation mechanism of the residual stress during quenching process. It should be notedthat a large number of experimental data of the core and shell materials are utilized for the wide range oftemperature considering the quenching process. The results verify that initially the tensile stress appears on the roll surface but finally the compressive stress occurs.Proceedings of 4th International Conference on Fracture Fatigue and Wear, FFW 2015, Ghent University, Belgium, 27-28 August 201
Dual supermassive black holes at close separation revealed by the Hyper Suprime-Cam Subaru Strategic Program
The unique combination of superb spatial resolution, wide-area coverage, and
deep depth of the optical imaging from the Hyper Suprime-Cam (HSC) Subaru
Strategic Program is utilized to search for dual quasar candidates. Using an
automated image analysis routine on 34,476 known SDSS quasars, we identify
those with two (or more) distinct optical point sources in HSC images covering
796 deg^2. We find 421 candidates out to a redshift of 4.5 of which one hundred
or so are more likely after filtering out contaminating stars. Angular
separations of 0.6 - 4.0" correspond to projected separations of 3 - 30 kpc, a
range relatively unexplored for population studies of luminous dual quasars.
Using Keck-I/LRIS and Gemini-N/NIFS, we spectroscopically confirm three dual
quasar systems at z < 1, two of which are previously unknown out of eight
observed, based on the presence of characteristic broad emission lines in each
component, while highlighting that the continuum of one object in one of the
pairs is reddened. In all cases, the [OIII]5007 emission lines have mild
velocity offsets, thus the joint [OIII] line profile is not double-peaked. We
find a dual quasar fraction of 0.26+/-0.18% and no evidence for evolution. A
comparison with the Horizon-AGN simulation seems to support the case of no
evolution in the dual quasar fraction when broadly matching the quasar
selection. These results may indicate a scenario in which the frequency of the
simultaneous triggering of luminous quasars is not as sensitive as expected to
the cosmic evolution of the merger rate or gas content of galaxies.Comment: 11 pages; 12 figures; Accepted for publication in The Astrophysical

First Data Release of the Hyper Suprime-Cam Subaru Strategic Program
The Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) is a three-layered
imaging survey aimed at addressing some of the most outstanding questions in
astronomy today, including the nature of dark matter and dark energy. The
survey has been awarded 300 nights of observing time at the Subaru Telescope
and it started in March 2014. This paper presents the first public data release
of HSC-SSP. This release includes data taken in the first 1.7 years of
observations (61.5 nights) and each of the Wide, Deep, and UltraDeep layers
covers about 108, 26, and 4 square degrees down to depths of i~26.4, ~26.5, and
~27.0 mag, respectively (5sigma for point sources). All the layers are observed
in five broad bands (grizy), and the Deep and UltraDeep layers are observed in
narrow bands as well. We achieve an impressive image quality of 0.6 arcsec in
the i-band in the Wide layer. We show that we achieve 1-2 per cent PSF
photometry (rms) both internally and externally (against Pan-STARRS1), and ~10
mas and 40 mas internal and external astrometric accuracy, respectively. Both
the calibrated images and catalogs are made available to the community through
dedicated user interfaces and database servers. In addition to the pipeline
products, we also provide value-added products such as photometric redshifts
and a collection of public spectroscopic redshifts. Detailed descriptions of
all the data can be found online. The data release website is

The Hobby–Eberly Telescope Dark Energy Experiment (HETDEX) Survey Design, Reductions, and Detections
We describe the survey design, calibration, commissioning, and emission-line detection algorithms for the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX). The goal of HETDEX is to measure the redshifts of over a million Lyα emitting galaxies between 1.88 < z < 3.52, in a 540 deg2 area encompassing a comoving volume of 10.9 Gpc3. No preselection of targets is involved; instead the HETDEX measurements are accomplished via a spectroscopic survey using a suite of wide-field integral field units distributed over the focal plane of the telescope. This survey measures the Hubble expansion parameter and angular diameter distance, with a final expected accuracy of better than 1%. We detail the project’s observational strategy, reduction pipeline, source detection, and catalog generation, and present initial results for science verification in the Cosmological Evolution Survey, Extended Groth Strip, and Great Observatories Origins Deep Survey North fields. We demonstrate that our data reach the required specifications in throughput, astrometric accuracy, flux limit, and object detection, with the end products being a catalog of emission-line sources, their object classifications, and flux-calibrated spectra
大学から発信する薬剤師・薬学生向けeラーニング教材のアウトカムと今後の課題
In order to confirm the efficacy of the medicine and early detection of adverse effects, we created avirtual physical assessment for e-learning materials for pharmacists/pharmacy students, which isavailable on the internet free of charge. In the breakdown of user attributes, pharmacists were the mostfrequent users, followed by pharmacy students, nurses, nutritionists, and others. “How to use astethoscope” was the most commonly accessed item in basic learning.“ Hearing heart sounds” had thehighest average access time. Furthermore, the access number for heart sounds was the highest fromamong the items in“ listening to sounds” in case learning. This suggested that the learner was interestedin listening to heart sounds using a stethoscope. Moreover, the accuracy rate of normal sounds of thelungs, heart and bowels was approximately 80%, but for abnormal sounds, it was less than 50%, exceptfor bubbling rale and Cheyne-Stokes respiration. In the future, the problems found in these educationaloutcomes need to be improved and used to create better teaching materials
