Background: One of important missions from American Collage of Sports Medicine (ASCM) is to support physical activity in community. During high impact physical activity, oxygen consumption in whole bodies are increasing 20 times. This increasing of oxygen consumption may lead to increase of free radical production that can cause cell damage. One of free radicals, Hydrogen peroxide causes damage in red blood cell (erythrocyte) membrane, with the result decreasing of red blood cell life time, moreover inducing anemia. Substance that can inhibit damage cell caused by free radical called antioxidant. Antioxidants are plentiful in fruit and vegetables, especially colorfull fruits and vegetables. One of fruit that well known as antioxidant source is red guava (Psidium guajava). Red guava containing lycopen which is has high antioxidant activity. The aim of this study is to understand effect of red guava juice treatment to red blood cell serum level in respondent who given physical activity. Standard of comparison in this study is vitamin C (zegavit 500 mg). Method: this study used quasi experiment, independent variable is vitamin C (zegavit 500 mg) and red guava juice treatment, dependent variable is red blood cell serum level. Results: The result of this study showed that there was no decreasing indication in red blood cells serum level of 3 groups. Conclusion: The conclusion in this study is there was no difference between red guava juice and vitamin C (zigavit 500 mg) treatment to avoid decreasing of red blood cells serum level after high impact physical activities.

The Polarization of X-Rays from Warped Black Hole Accretion Disks
Authors: Abarr Quincy , Krawczynski Henric 
Published: January 2020

Abstract
It is commonly assumed that in black hole (BH) accretion disks the angular momenta of the disk and the BH are aligned. However, for a significant fraction of stellar-mass BHs and supermassive BHs, the momenta may not be aligned. In such systems, the interplay of disk viscosity and general relativistic frame dragging can cause the disk to warp or break into two (or more) distinct planes; this is called the Bardeen–Petterson effect. We have developed a general relativistic ray-tracing code to find the energy spectra and polarization of warped accretion disks, accounting for the emission from the disk and for photons reflecting one or multiple times off the warped accretion disk segments. We find that polarization angle can be used to give a lower limit on the misalignment angle when a previous measurement of the jet, which is thought be aligned with the BH angular momentum, can be spatially resolved.
Using Multi-line Spectropolarimetric Observations of Forbidden Emission Lines to Measure Single-point Coronal Magnetic Fields
Authors: Dima Gabriel I. , Schad Thomas A. 
Published: January 2020

Abstract
Polarized magnetic dipole (M1) emission lines provide important diagnostics for the magnetic field dominating the evolution of the solar corona. This paper advances a multi-line technique using specific combinations of M1 lines to infer the full vector magnetic field for regions of optically thin emission that can be localized along a given line of sight. Our analytical formalism is a generalization of the “single-point inversion” approach introduced by Plowman. We show that combinations of M1 transitions for which each is either a

transition or has equal Landé g-factors for the upper and lower levels contain degenerate spectropolarimetric information that prohibits the application of the single-point inversion technique. This may include the pair of Fe xiii lines discussed by Plowman. We identify the Fe xiii 10747 Å and Si x 14301 Å lines as one alternative combination for implementing this technique. Our sensitivity analysis, based on coronal loop properties, suggests that for photon noise levels around 10−4 of the line intensity, which will be achievable with the National Science Foundation’s Daniel K. Inouye Solar Telescope, magnetic fields with sufficient strength (∼10 G) and not severely inclined to the line of sight (≲35°) can be recovered with this method. Degenerate solutions exist, though we discuss how added constraints may help resolve them or reduce their number.

Abstract
We study the

luminosity line ratio in a sample of nearby (z < 0.05) galaxies: 25 star-forming galaxies (SFGs) from the xCOLD GASS survey, 36 hard X-ray-selected active galactic nucleus (AGN) host galaxies from the BAT AGN Spectroscopic Survey, and 37 infrared-luminous galaxies from the SCUBA Local Universe Galaxy Survey. We find a trend for r
31 to increase with star formation efficiency (SFE). We model r
31 using the UCL-PDR code and find that the gas density is the main parameter responsible for the variation of r
31, while the interstellar radiation field and cosmic-ray ionization rate play only a minor role. We interpret these results to indicate a relation between SFE and gas density. We do not find a difference in the r
31 value of SFGs and AGN host galaxies, when the galaxies are matched in SSFR (〈r
31〉 = 0.52 ± 0.04 for SFGs and 〈r
31〉 = 0.53 ± 0.06 for AGN hosts). According to the results of the UCL-PDR models, the X-rays can contribute to the enhancement of the CO line ratio, but only for strong X-ray fluxes and for high gas density (n
H > 104 cm−3). We find a mild tightening of the Kennicutt–Schmidt relation when we use the molecular gas mass surface density traced by CO(3–2) (Pearson correlation coefficient R = 0.83), instead of the molecular gas mass surface density traced by CO(1–0) (R = 0.78), but the increase in correlation is not statistically significant (p-value = 0.06). This suggests that the CO(3–2) line can be reliably used to study the relation between SFR and molecular gas for normal SFGs at high redshift and to compare it with studies of low-redshift galaxies, as is common practice.

Abstract
High synchrotron peak (HSP;

Hz) BL Lac objects are some of the most extreme accelerators in the universe. Those found at high redshifts (z > 1) challenge our understanding of blazar evolution models and are crucial for cosmological measurements of the extragalactic background light. In this paper, we study a high-z BL Lac object, 4FGL J2146.5-1344, detected to be at z = 1.34 using the photometric dropout technique. We collected multiwavelength data for this source from optical up to γ-rays, in order to study its spectral energy distribution (SED). In particular, this source was observed for the first time with the Nuclear Spectroscopic Telescope Array, which accurately measures the synchrotron emission of this blazar up to 50 keV. Despite being classified as an HSP BL Lac object, the modeling of the SED reveals that this source likely belongs to the “masquerading BL Lac” class, which comprises flat spectrum radio quasars appearing as disguised BL Lac objects.
The Original Anisotropy of TeV Cosmic Rays in the Local Interstellar Medium

Published: January 2020

Abstract
This paper presents the original anisotropy that TeV cosmic rays (CRs) have in the local interstellar medium. This anisotropy is obtained using a method of flux mapping with the Liouville theorem and a magnetohydrodynamic (MHD) heliosphere model of the electromagnetic field to remove the particle propagation effects hidden in the measurements made by the Tibet ASγ experiment at Earth. The original interstellar anisotropy turns out to be almost a pure dipole, which results from a diffusion flow of CRs escaping along the local interstellar magnetic field into the northern Galactic halo. The observed anisotropy maps at Earth appear quite complex because the heliosphere distorts the dipole anisotropy, generating a significant amount of high-order multipoles, while interstellar magnetic field fluctuations contribute to some weak anisotropy on small angular scales. It is found that the density gradient of these CRs points approximately toward Vela in the Local Bubble, providing experimental evidence to show that the local supernova is making a special contribution to the TeV CRs we see at Earth. This special contribution will keep growing in the future tens of thousand years. The original anisotropy also reveals that the CRs spread from the source primarily along the interstellar magnetic field, while experiencing a nearly isotropic pitch-angle scattering process caused by interstellar turbulence.

Abstract
We report two secure (

) and one tentative (z ≈ 3.767) spectroscopic confirmations of massive and quiescent galaxies through K-band observations with Keck/MOSFIRE and Very Large Telescope/X-Shooter. The stellar continuum emission, absence of strong nebular emission lines, and lack of significant far-infrared detections confirm the passive nature of these objects, disfavoring the alternative solution of low-redshift dusty star-forming interlopers. We derive stellar masses of log(M

⊙) ∼ 11 and ongoing star formation rates placing these galaxies ≳1–2 dex below the main sequence at their redshifts. The adopted parameterization of the star formation history suggests that these sources experienced a strong (

M
⊙ yr−1) and short (∼50 Myr) burst of star formation, peaking ∼150–500 Myr before the time of observation, all properties reminiscent of the characteristics of submillimeter galaxies (SMGs) at z > 4. We investigate this connection by comparing the comoving number densities and the properties of these two populations. We find a fair agreement only with the deepest submillimeter surveys detecting not only the most extreme starbursts but also more normal galaxies. We support these findings by further exploring the Illustris TNG cosmological simulation, retrieving populations of both fully quenched massive galaxies at z ∼ 3–4 and SMGs at z ∼ 4−5, with number densities and properties in agreement with the observations at z ∼ 3 but in increasing tension at higher redshift. Nevertheless, as suggested by the observations, not all of the progenitors of quiescent galaxies at these redshifts shine as bright SMGs in their past, and, similarly, not all bright SMGs quench by z ∼ 3, both fractions depending on the threshold assumed to define the SMGs themselves.
A Unified Framework for X-shaped Radio Galaxies
Authors: Garofalo David , Joshi Ravi , Yang Xiaolong , Singh Chandra B. , North Max , Hopkins Matthew 
Published: January 2020

Abstract
We propose a radically different picture for X-shaped radio galaxies compared with existing models as transition objects between cold-mode accreting, low-spinning retrograde black holes and low-spinning prograde black holes. This model explains their smaller average black hole masses; their general aversion for cluster compared with isolated environments; the negligible difference in spectral index between primary and secondary jets, despite a time difference in their formation; their absence among the most powerful radio quasars and radio galaxies; and their connection to the elusive Fanaroff–Riley I quasar class, among others. The key to their formation is cold gas accretion onto Schwarzschild black holes.
Testing the Prediction of Fuzzy Dark Matter Theory in the Milky Way Center
Authors: Li 李 Zhi 智 , Shen 沈 Juntai 俊太 , Schive 薛 Hsi-Yu 熙于 
Published: January 2020

Abstract
The fuzzy dark matter model (FDM; also known as quantum wave dark matter model) argues that light bosons with a mass of

are a possible candidate for dark matter in the universe. One of the most important predictions of FDM is the formation of a soliton core instead of a density cusp at the center of galaxies. If FDM is the correct theory of dark matter, then the predicted soliton core can help form the Central Molecular Zone (CMZ) in the Milky Way. We present high-resolution hydrodynamical simulations of gas flow patterns to constrain the properties of the soliton core based on a realistic Milky Way potential. We find that a dense center is required to form a reasonable CMZ. The size and kinematics of the CMZ offer a relatively strong constraint on the inner enclosed mass profile of the Galaxy. If a soliton core is not considered, a compact nuclear bulge alone with a radially varying mass-to-light ratio can match the observed size and kinematics of the CMZ. A soliton core model with a mass of

and a core radius of

, together with a less massive nuclear bulge with a constant mass-to-light ratio, also agrees nicely with the current data. Such an FDM soliton core corresponds to a boson mass of

, which could be further constrained by the improved determination of the mass-to-light ratio in the Galactic center.
