Abstract
We present a “super-deblended” far-infrared (FIR) to (sub)millimeter photometric catalog in the Cosmic Evolution Survey (COSMOS), prepared with the method recently developed by Liu et al., with key adaptations. We obtain point-spread function fitting photometry at fixed prior positions including 88,008 galaxies detected in VLA 1.4, 3 GHz, and/or MIPS 24 μm images. By adding a specifically carved mass-selected sample (with an evolving stellar mass limit), a highly complete prior sample of 194,428 galaxies is achieved for deblending FIR/(sub)mm images. We performed “active” removal of nonrelevant priors at FIR/(sub)mm bands using spectral energy distribution fitting and redshift information. In order to cope with the shallower COSMOS data, we subtract from the maps the flux of faint nonfitted priors and explicitly account for the uncertainty of this step. The resulting photometry (including data from Spitzer, Herschel, SCUBA2, AzTEC, MAMBO, and NSF’s Karl G. Jansky Very Large Array at 3 and 1.4 GHz) displays well-behaved quasi-Gaussian uncertainties calibrated from Monte Carlo simulations and tailored to observables (crowding, residual maps). Comparison to ALMA photometry for hundreds of sources provides a remarkable validation of the technique. We detect 11,220 galaxies over the 100–1200 μm range extending to z
phot ∼ 7. We conservatively selected a sample of 85 z > 4 high-redshift candidates significantly detected in the FIR/(sub)mm, often with secure radio and/or Spitzer/IRAC counterparts. This provides a chance to investigate the first generation of vigorous starburst galaxies (SFRs ∼ 1000 M
⊙ yr−1). The photometric and value-added catalogs are publicly released.
A Systematic Analysis of Stellar Populations in the Host Galaxies of SDSS Type I QSOs

Published: August 2018

Abstract
We investigate the relationship between host galaxies’ stellar content and active galactic nuclei (AGNs) for optically selected QSOs with z < 0.5. There is a total of 82 QSOs that we select from the Sloan Digital Sky Survey. These 82 QSOs have both Wide-field Infrared Survey Explorer data and measurable stellar content. With the help of the stellar population synthesis code STARLIGHT, we determine the luminosity fractions of AGNs, stellar population ages, and star formation histories (SFHs) of host galaxies. We find that there is a correlation between the SFH and AGN properties, which suggests a possible delay from star formation to AGN. This probably indicates that the AGN activity correlates with the star formation activity, which consistent with a coevolution scheme for black hole and host galaxies.
The Opacity of the Intergalactic Medium Measured along Quasar Sightlines at z ∼ 6

Published: August 2018

Abstract
We publicly release a new sample of 34 medium resolution quasar spectra at 5.77 ≤ z
em ≤ 6.54 observed with the Echellette Spectrograph and Imager on the Keck telescope. This quasar sample represents an ideal laboratory to study the intergalactic medium (IGM) during the end stages of the epoch of reionization, and constrain the timing and morphology of the phase transition. For a subset of 23 of our highest signal-to-noise ratio spectra (S/N > 7, per 10 km s−1 pixel), we present a new measurement of the Lyα forest opacity spanning the redshift range 4.8 ≲ z ≲ 6.3. We carefully eliminate spectral regions that could be causing biases in our measurements due to additional transmitted flux in the proximity zone of the quasars, or extra absorption caused by strong intervening absorption systems along the line of sight. We compare the observed evolution of the IGM opacity with redshift to predictions from a hydrodynamical simulation with uniform ultraviolet background (UVB) radiation, as well as two semi-numerical patchy reionization models, one with a fluctuating UVB and another with a fluctuating temperature field. Our measurements show a steep rise in opacity at z ≳ 5.0 and an increased scatter and thus support the picture of a spatially inhomogeneous reionization process, consistent with previous work. However, we measure significantly higher optical depths at 5.3 ≲ z ≲ 5.7 than previous studies, which reduces the contrast between the highest opacity Gunn–Peterson troughs and the average opacity trend of the IGM, which may relieve some of the previously noted tension between these measurements and reionization models.

Abstract
The orientation of galaxy spin vectors within the large-scale structure has been considered an important test of our understanding of structure formation. We investigate the angular changes of galaxy spin vectors in clusters—denser environments than are normally focused upon—using hydrodynamic zoomed simulations of 17 clusters YZiCS and a set of complementary controlled simulations. The magnitude by which galaxies change their spin vector is found to be a function of their rotational support, with larger cumulative angular changes of spin vectors when they have initially lower V

θ
/σ. We find that both mergers and tidal perturbations can significantly swing spin vectors, with larger changes in spin vector for smaller pericenter distances. Strong tidal perturbations are also correlated with the changes in stellar mass and specific angular momentum of satellite galaxies. However, changes in spin vector can often result in a canceling out of previous changes. As a result, the integrated angular change is always much larger than the angular change measured at any instant. Also, overall, the majority of satellite galaxies do not undergo mergers or sufficiently strong tidal perturbation after infall into clusters, and thus they end up suffering little change to their spin vectors. Taken as a whole, these results suggest that any signatures of spin alignment from the large-scale structure will be preserved in the cluster environment for many gigayears.
Magnetic Flux Cancelation as the Buildup and Trigger Mechanism for CME-producing Eruptions in Two Small Active Regions
Authors: Sterling Alphonse C. , Moore Ronald L. , Panesar Navdeep K. 
Published: August 2018

Abstract
We follow two small, magnetically isolated coronal mass ejection (CME)-producing solar active regions (ARs) from the time of their emergence until several days later, when their core regions erupt to produce the CMEs. In both cases, magnetograms show: (a) following an initial period where the poles of the emerging regions separate from each other, the poles then reverse direction and start to retract inward; (b) during the retraction period, flux cancelation occurs along the main neutral line of the regions; (c) this cancelation builds the sheared core field/flux rope that eventually erupts to make the CME. In the two cases, respectively 30% and 50% of the maximum flux of the region cancels prior to the eruption. Recent studies indicate that solar coronal jets frequently result from small-scale filament eruptions, with those “minifilament” eruptions also being built up and triggered by cancelation of magnetic flux. Together, the small-AR eruptions here and the coronal jet results suggest that isolated bipolar regions tend to erupt when some threshold fraction, perhaps in the range of 50%, of the region's maximum flux has canceled. Our observed erupting filaments/flux ropes form at sites of flux cancelation, in agreement with previous observations. Thus, the recent finding that minifilaments that erupt to form jets also form via flux cancelation is further evidence that minifilaments are small-scale versions of the long-studied full-sized filaments.
Signature of Planetary Mergers on Stellar Spins

Published: August 2018

Abstract
One of the predictions of high-eccentricity planetary migration is that many planets will end up plunging into their host stars. We investigate the consequence of planetary mergers on their stellar hosts’ spin period. Energy and angular momentum conservation indicate that planet consumption by a star will spin up the star. We find that our proof-of-concept calculations align with the observed bifurcation in the stellar spin-period in young clusters. For example, after a Sun-like star has eaten a Jupiter-mass planet it will spin up by ∼60% (i.e., spin period is reduced by ∼60%), causing an apparent gap in the stellar spin-period between stars that consumed a planet and those that did not. The spun-up star will later spin down due to magnetic braking, consistent with the disappearance of this bifurcation in clusters (≳300 Myr). The agreement between the calculations presented here and the observed spin-period color diagram of stars in young clusters provides circumstantial evidence that planetary accretion onto their host stars is a generic feature of planetary-system evolution.
NGC 7793 P9: An Ultraluminous X-Ray Source Evolved from a Canonical Black Hole X-Ray Binary

Published: August 2018

Abstract
Transient ultraluminous X-ray sources (ULXs) provide an important link bridging transient low-mass X-ray binaries and ULXs. Here we report the first discovery of both a canonical sub-Eddington outburst and an ultraluminous super-Eddington outburst from an unusual transient ULX, NGC 7793 P9, with a variability factor higher than 103. Its X-ray spectrum switches between the typical high/soft state and the steep power-law state during the canonical outburst. The inner radius of the accretion disk and the disk temperature–luminosity correlation suggest that P9 harbors a stellar-mass black hole (BH). At the beginning of the ultraluminous outburst, we observe a cool outer disk with a hard Comptonized spectrum, implying a transition to the ULX regime. When the luminosity increases to L ≳ 3 × 1039 erg s−1, P9 shows a significantly curved spectrum that can be described by either a slim disk or a strongly curved Comptonized corona. The phenomenological model suggests that the hot disk observed near the peak of the ultraluminous outburst is coincidentally consistent with the extension of the thermal track. Utilizing more physical Comptonized disk models, we suggest that the corona cools down and the apparent disk-like spectrum is dominated by soft Comptonization. The significant variability above 1 keV supports this two-component scenario. The spectral evolution can also be interpreted with the supercritical accretion model. All these indicate that a canonical BH X-ray binary can show properties of a ULX.
On the Orbital Properties of Millisecond Pulsar Binaries
Authors: Hui C. Y. , Wu Kinwah , Han Qin , Kong A. K. H. , Tam P. H. T. 
Published: August 2018

Abstract
We report a detailed analysis of the orbital properties of a binary millisecond pulsar (MSP) with a white dwarf (WD) companion. Positive correlations between the orbital period P
b and eccentricity ϵ are found in two classes of MSP binaries with a He WD and with a CO/ONeMg WD, though their trends are different. The distribution of P
b is not uniform. Deficiency of sources at P
b ∼ 35–50 days (Gap 1) have been mentioned in previous studies. On the other hand, another gap at P
b ∼ 2.5–4.5 days (Gap 2) is identified for the first time. Inspection of the relation between P
b and the companion masses M
c revealed the subpopulations of MSP binaries with a He WD separated by Gap 1, above which P
b is independent of M
c (horizontal branch) but below which P
b correlates strongly with M
c (lower branch). A distinctive horizontal branch and a lower branch separated by Gap 2 were identified for the MSP binaries with a CO/ONeMg WD at shorter P
b and higher M
c. Generally, M
c are higher in the horizontal branch than in the lower branch for the MSP binaries with a He WD. These properties can be explained in terms of a binary orbital evolution scenario in which the WD companion was ablated by a pulsar wind in the post-mass-transfer phase.

Abstract
Transitional millisecond pulsars are accreting millisecond pulsars that switch between accreting X-ray binary and millisecond radio pulsar states. Only a handful of these objects have been identified so far. Terzan 5 CX1 is a variable hard-X-ray source in the globular cluster Terzan 5. In this paper, we identify a radio counterpart to CX1 in deep Very Large Array radio continuum data. Chandra observations over the last 14 years indicate that CX1 shows two brightness states: in 2003 and 2016 the source was the brightest X-ray source in the cluster (at L
X ∼ 1033 erg s−1), while in many intermediate observations, its luminosity was almost an order of magnitude lower. We analyze all available X-ray data of CX1, showing that the two states are consistent with the spectral and variability properties observed for the X-ray active and radio pulsar states of known transitional millisecond pulsars. Finally, we discuss the prospects for the detection of CX1 as a radio pulsar in existing timing data.
Universal Design for Virtual Worlds
Authors: Krueger Alice , Ludwig Ann , Ludwig David 
Published: August 2018

We describe three broad approaches to the issue of accessibility design within Virtual Worlds. Our intent is to stimulate the thinking of content designers within Virtual Worlds about these approaches.
Approach 1: Minimal accessibility design principles incorporated into the Virtual World
For much of the current state of Virtual Worlds, this is the default situation: Minimal consideration has been given during design or construction to accessibility issues. This may be the preferred approach when the intent of the designer is artistic creativity.
Approach 2: Emulate Real World accessibility design principles in the Virtual World
In this approach, the designer replicates various aspects of Real World accessibility within the virtual setting. This approach is preferred when the intent is to create learning opportunities about Real World Universal Design or accessibility standards and requirements.
Approach 3: Incorporate only accessibility design principles that are appropriate for the Virtual World
This approach is focused entirely on the virtual environment. The only constraints of importance to the designer are those of the technology itself; Real World accessibility standards are not considered relevant.
We then use these three perspectives to address Virtual World accessibility in landscapes, structures, movement, communication, and perceived environments.
Designers should consider which approach best fits the desired intent and audience of their creation.
We advocate that for most builds, designers incorporate accessibility principles that are appropriate for the Virtual World, and not be constrained to a literal translation of Real World standards and requirements. We conclude that this is a definition of Universal Design for Virtual Worlds.
‘Othering’ and ‘Self-othering’ in the Book of Tobit: A Jungian approach
Authors: Efthimiadis-Keith Helen 
Published: August 2018

The Book of Tobit is replete with various instances of ‘othering’ that hold the potential for alienation and a variety of strong emotions. For example, Tobit ‘others’ Anna by insisting that she had stolen a goat, whereas she had not. Following a Jungian paradigm, this paper reads the various ‘otherings’ inherent in the interrelationships between the characters as reflections of the main character’s relationship with himself. In so doing, it analyses these relationships through Jung’s concepts of Eros/Logos and anima/animus to determine the nature of Tobit’s ‘self-othering’ and its effect on those around him. It is concluded, among others, that Tobit’s multiple ‘self-otherings’ and his ‘othering’ of ‘other’ characters are because of his suppression of his anima-Eros function that has, in turn, given rise to a dominant (and demonic) animus-Logos.
Systematic Theology – An experiential approach: Core assumptions of my ‘Invitation to Systematic Theology’
Authors: Nürnberger Klaus 
Published: August 2018

Nürnberger’s ‘Faith in Christ Today: Invitation to Systematic Theology’ is meant to serve the proclamation of the Word of God in modern times. Based on ‘experiential realism’, as used by science, it restricts itself to immanent reality, avoids the reification of idealised abstractions and biblical metaphors and follows an emergent-evolutionary hermeneutic. God’s self-disclosure manifests itself as (1) creative power in the cosmic process as explored by science, (2) benevolent intentionality as proclaimed on the basis of the Christ-event and (3) a motivating and transforming vision in the community of believers. Classical doctrines are reconceptualised in action terms, rather than ontological terms. Christology: The ministry, death and elevation of Jesus of Nazareth as God’s messianic representative manifest God’s redemptive intentionality. Trinity: The God manifest in Christ is identical with the God of Israel and the Creator of the universe and the divine Spirit transforming and empowering the community of believers. Eschatology: The thrust of God’s vision of comprehensive optimal well-being moves through time like a horizon opening up ever new vistas, challenges and opportunities.Intradisciplinary and/or interdisciplinary implications: The task of Systematic Theology is to offer as comprehensive and consistent a presentation of the Christian faith as possible under current circumstances. This involves the retrieval of the biblical message from its ancient conceptualisations and to repackage it in current world view assumptions. To reach a readership informed by modern science, technology, commerce and the consumer culture, Nürnberger’s Systematic Theology applies the approach of experiential realism as practised by the positive sciences: restricting its analyses to immanent reality and avoiding metaphysical constructs. It follows a consistent emergent-evolutionary hermeneutic and works on an interdisciplinary basis, using insights from modern physics, biology, neurology and sociology. God is conceptualised as the transcendent Source and Destiny of experienced reality. The core of the Christian message is God’s suffering, transforming acceptance of the unacceptable, which involves us in its dynamics. It is geared to transformation rather than perfection. It is applied to all aspects of reality, including, for example, entropy, death and natural evil and so on. In this way, the author hopes to help Christians to regain their intellectual integrity and the credibility of their message.
Responses of developmental and physiological traits to manipulated incubation conditions in broiler embryos at hypoxic high altitude
Authors: Babacanoğlu Elif 
Published: August 2018

Abstract. The effects of hypoxia at
increased altitude levels on the cardio-respiratory development of broiler
embryos are distinct in comparison with those at sea level. The aim of the
study was to investigate the effects of high incubation temperature (H) and
oxygen supplementation (O) during hypoxic high altitude (HA) on developmental
and physiological traits of embryos and hatching performance of embryonated
hatching eggs in broilers at different embryonic stages. A total of 1280 eggs
obtained from broiler breeders laid at sea level were used. Eggshell quality
characteristics were measured for 20 eggs. The rest of the 1260 eggs were
divided into seven incubation condition (IC) groups (180 eggs per group)
including a control group at 37.8 ∘C and 21 % O2; O
groups, with daily 1 h 23.5 % O2 supplementation at
37.8 ∘C as O0−11, O12−21, and O18−21; H groups
at 38.5 ∘C high incubation temperature at 21 % O2 as
H0−11, H12−21, and H18−21 from days 0 to 11, 12 to 21, and 18 to 21 of incubation,
respectively. All groups were incubated in three different incubators at
hypoxic HA. The effect of IC was determined on eggshell temperature, hatching
performance, embryo development, right ventricular (RV) to total ventricular
(TV) ratio, and blood parameters. The highest egg water loss and embryonic
mortality and the lowest hatchability were in the H0−11 group, which
depended on increased eggshell temperature during incubation. On day 18 of
incubation, due to the decreased egg water loss in the O12−21 and
O18−21 groups, there was an increase in hatchability in fertile eggs
similar to the middle and late H groups. Towards the end of incubation,
embryo/chick weights were not different and RV and TV weights increased in
the treated groups, and the RV ∕ TV ratio changed between 15 and
26 %. At hatching, yolk
sac weight increased in H0−11 and H12−21 groups. The O groups
had the lowest serum tri-iodothyronine (T3) concentration as distinct
from H groups. The serum thyroxine (T4) concentration increased in the
treated groups, dependent on sex of the embryo. Blood hemoglobin
concentration of O groups decreased relative to other groups. The hematocrit
value was the lowest in the O12−21 and highest in the H12−21
groups. The H and O treatments during pre-hatch hypoxic HA condition can be
positively evaluated on physiological traits of embryos after half of
incubation depended on the timing of the IC exposure to the hatching eggs
obtained from broiler breeders at sea level.
