The Swan: Data-driven Inference of Stellar Surface Gravities for Cool Stars from Photometric Light Curves
Authors: Sayeed Maryum , Huber Daniel , Wheeler Adam , Ness Melissa K. 
Published: March 2021

Abstract
Stellar light curves are well known to encode physical stellar properties. Precise, automated, and computationally inexpensive methods to derive physical parameters from light curves are needed to cope with the large influx of these data from space-based missions such as Kepler and TESS. Here we present a new methodology that we call “The Swan,” a fast, generalizable, and effective approach for deriving stellar surface gravity (

) for main-sequence, subgiant, and red giant stars from Kepler light curves using local linear regression on the full frequency content of Kepler long-cadence power spectra. With this inexpensive data-driven approach, we recover

to a precision of ∼0.02 dex for 13,822 stars with seismic

values between 0.2 and 4.4 dex and ∼0.11 dex for 4646 stars with Gaia-derived

values between 2.3 and 4.6 dex. We further develop a signal-to-noise metric and find that granulation is difficult to detect in many cool main-sequence stars (T
eff ≲ 5500 K), in particular K dwarfs. By combining our

measurements with Gaia radii, we derive empirical masses for 4646 subgiant and main-sequence stars with a median precision of ∼7%. Finally, we demonstrate that our method can be used to recover

to a similar mean absolute deviation precision for a TESS baseline of 27 days. Our methodology can be readily applied to photometric time series observations to infer stellar surface gravities to high precision across evolutionary states.
The Dielectric Function of “Astrodust” and Predictions for Polarization in the 3.4 and 10 μm Features
Authors: Draine B. T. , Hensley Brandon S. 
Published: March 2021

Abstract
The dielectric function of interstellar dust material is modeled using observations of extinction and polarization in the infrared, together with estimates for the mass of interstellar dust. The “astrodust” material is assumed to be a mix of amorphous silicates and other materials, including hydrocarbons producing an absorption feature at 3.4 μm. The detailed shape of the 10 μm polarization profile depends on the assumed porosity and grain shape, but the 10 μm spectropolarimetric data are not yet good enough to clearly favor one shape over another, nor to constrain the porosity. The expected 3.4 μm feature polarization is consistent with existing upper limits, provided the 3.4 μm absorption is preferentially located in grain surface layers; a separate population of non-aligned carbonaceous grains is not required. We predict the 3.4 μm polarization feature to be (Δp)3.4 μm/p(10 μm) ≈ 0.016, just below current upper limits. Polarization by the same grains at submillimeter wavelengths is also calculated.
Mass and Density of Asteroid (16) Psyche
Authors: Siltala Lauri , Granvik Mikael 
Published: March 2021

Abstract
We apply our novel Markov Chain Monte Carlo (MCMC)–based algorithm for asteroid mass estimation to asteroid (16) Psyche, the target of NASA’s eponymous Psyche mission, based on close encounters with 10 different asteroids, and obtain a mass of (1.117 ± 0.039) × 10−11
M
⊙. We ensure that our method works as expected by applying it to asteroids (1) Ceres and (4) Vesta, and find that the results are in agreement with the very accurate mass estimates for these bodies obtained by the Dawn mission. We then combine our mass estimate for Psyche with the most recent volume estimate to compute the corresponding bulk density as (3.88 ± 0.25) g cm−3. The estimated bulk density rules out the possibility of Psyche being an exposed, solid iron core of a protoplanet, but is fully consistent with the recent hypothesis that ferrovolcanism would have occurred on Psyche.
A Stationary Drake Equation Distribution as a Balance of Birth-death Processes
Authors: Kipping David 
Published: March 2021

Abstract
Previous critiques of the Drake Equation have highlighted its deterministic nature, implying that the number of civilizations is the same at all times. Here, I build upon earlier work and present a stochastic formulation. The birth of civilizations within the galaxy is modeled as following a uniform rate (Poisson) stochastic process, with a mean rate of λ

C
. Each then experiences a constant hazard rate of collapse, which defines an exponential distribution with rate parameter λ

L
. Thus, the galaxy is viewed as a frothing landscape of civilization birth and collapse. Under these assumptions, I show that N in the Drake Equation must follow another Poisson distribution, with a mean rate (λ

C
/λ

L
). This is used to demonstrate why the Copernican Principle does not allow one to infer N, as well evaluating the algebraic probability of being alone in the galaxy.

Abstract
Expanding on the work of Snyder et al., we present merger pair analysis of mock surveys from the IllustrisTNG suite of 3D cosmological simulations. Our results, shown in the context of previous work with Illustris-1, are consistent with a flattening of the pair fraction curve at a redshift of z = 2.
Effect of bismuth additions on the thermophysical and thermodynamical properties of E-AlMgSi (Aldrey) aluminum semiconductor alloy

The economic feasibility of using aluminum as a conductive material is explained by the favorable ratio of its cost to the cost of copper. In addition, one should take into account that the cost of aluminum has remained virtually unchanged for many years.
When using conductive aluminum alloys for the manufacture of thin wire, winding wire, etc., certain difficulties may arise in connection with their insufficient strength and a small number of kinks before fracture. Aluminum alloys have been developed in recent years which even in a soft state have strength characteristics that allow them to be used as a conductive material.
The electrochemical industry is one of the promising application fields of aluminum. E-AlMgSi (Aldrey) conductor aluminum alloys represent this group of alloys. This work presents data on the temperature dependence of heat capacity, heat conductivity and thermodynamic functions of the E-AlMgSi (Aldrey) aluminum alloy doped with bismuth. The studies have been carried out in "cooling" mode. It has been shown that the heat capacity and thermodynamic functions of the E-AlMgSi (Aldrey) aluminum alloy doped with bismuth increase with temperature and the Gibbs energy decreases. Bismuth additions of up to 1 wt.% reduce the heat capacity, heat conductivity, enthalpy and entropy of the initial alloy and increase the Gibbs energy.

Published: March 2021

Introduction: The His-Phe-Arg-Trp sequence corresponding to the 6-9th amino acid residue of the adrenocorticotropic hormone molecule (ACTH6-9) is the critical pharmacophore of all endogenous melanocortin receptor agonists. In order to effects prolongation it may be stabilized by the addition of the amino acid sequence Pro-Gly-Pro (PGP) to the C-terminus. The aim of this work was to study the effect of ACTH6-9-PGP (HFRWPGP) on the processes of memory consolidation in the model of passive avoidance conditioning in comparison with ACTH4-7-PGP effects.
Materials and methods: The study was carried out on the model of passive avoidance conditioning. The effects of ACTH6-9-PGP were studied after its intraperitoneal injection to male Wistar rats at doses of 0.5, 5, 50, 150, and 450 μg/kg 15 minutes before the experiment, whereas the effects of ACTH4-7-PGP– under the similar conditions at doses of 50, 150, and 450 μg/kg.
Results and discussion: It was found that ACTH6-9-PGP had a pronounced stimulating effect on the memory consolidation process in the dose range from 0.5 μg/kg to 150 μg/kg, significantly increasing the latent period of an animal entering the dark chamber. Administration of ACTH4-7-PGP led to an improvement in the consolidation processes of the acquired conditioned reflex at the doses of 50 μg/kg and 450 μg/kg.
Conclusion: The range of effective doses of ACTH6-9-PGP is lower than that of ACTH4-7-PGP, which indicates the greater activity of HFRWPGP sequence in relation to memory consolidation processes and allows considering this peptide as a promising molecule for creating nootropic pharmacological drugs.

Published: March 2021

AbstractIn this work, we used measures of diversity and biogeographic patterns to evaluate the response of dung-beetle assemblages (Coleoptera: Scarabaeidae: Scarabaeinae) at two cattle ranches with different management systems on the southern Mexican High Plateau. The number of individuals and biomass were used as the primary diversity attributes of the assemblage. The 1D and 2D true diversity indexes of these attributes were examined, and the attributes were classified according to Halffter’s biogeographical patterns. In total, 1375 Scarabaeinae adults were collected, representing 11 species and seven genera. Site management regime did not significantly affect species richness or assemblage structure when the number of individuals was considered. However, species diversity and biomass turnover were higher in the system with holistic management than in that with semitechnified management. The proportions of Halffter’s biogeographical patterns also differed between the two production systems. In conclusion, the location under holistic management, despite having cattle production, contained a significant proportion of the Scarabaeinae species that are typical of the Mexican High Plateau. In contrast, the semitechnified system negatively impacted beetle abundance, leading to half the individuals, the dominance of species with high biomass, and the absence of groups typical of the region.
A prospective randomized double-blinded study of dexmedetomidine versus propofol infusion for orbital surgeries
Authors: Mukherjee Bipasha , Backiavathy Varsha , Sujatha R. 
Published: March 2021

PURPOSE:
Orbital surgeries are traditionally taken up under general anesthesia. Local anesthesia combined with moderate sedation can also be considered as an alternative option. This study was performed to compare the safety and efficacy of dexmedetomidine and propofol infusion for orbital surgeries under local anesthesia.

METHODS:
Twenty patients undergoing orbital surgery by a single surgeon were enrolled in this prospective randomized study. Selected patients were randomly administered dexmedetomidine (Group D) or propofol (Group P). Hemodynamic and respiratory effects, sedation levels, recovery profile, analgesic properties, and satisfaction levels of the patients and the surgeon were assessed.

RESULTS:
There was a significant decrease in mean arterial pressures following drug administration compared to initial measurements in both the groups. However, a statistically significant decrease in heart rate was observed only in Group P. The sedation score at the end of loading dose was 3.3 ± 0.82 in Group D and 2.5 ± 0.52 in Group P and this difference was also statistically significant (P value-0.027). The surgeon's satisfaction score was 6.5 ± 0.71 in Group D and 5.6 ± 1.07 in Group P (P value – 0.045). There were no statistically significant differences observed in patients' satisfaction, pain, and anxiety scores in either group. No major hemodynamic changes or complications were noted in either of the groups.

CONCLUSION:
Dexmedetomidine, in comparison to propofol, provides better sedation levels with good hemodynamic stability. It also offers better surgeon satisfaction, thus providing a useful alternative for general anesthesia in selective patients undergoing orbital surgery.
Inverting peripheral hyperopic defocus into myopic defocus among myopic schoolchildren using addition power of multifocal contact lens
Authors: Allinjawi Kareem , Kaur Sharanjeet , Akhir Saadah M. , Mutalib Haliza A. 
Published: March 2021

PURPOSE:
The purpose was to determine the minimum near-addition power needed using Proclear® multifocal D-Design contact lens (adds: +1.50 D, +2.50 D, +3.00 D, and +3.50 D) to invert the pattern of relative hyperopic defocus in the peripheral retina into relative myopic defocus among the eyes of myopic schoolchildren.

METHODS:
Twenty-seven right eyes (24 females and 3 males) of 27 myopic schoolchildren aged between 13 and 15 years were included in this study. The measurements of central refraction, peripheral refraction (between 35° temporal and 35° nasal visual field in 5° steps), and lag of accommodation were conducted using the Grand-Seiko WR-5100K open-field autorefractometer initially without correction (WC), followed by with correction using four different addition powers of Proclear® multifocal D-Design contact lens in random sequence. Axial length was measured using a handheld probe ultrasound A-scan (Tomey AL-2000).

RESULTS:
The relative peripheral refractive error showed high hyperopic defocus of +1.08 ± 1.24 D at 35° nasal and +1.06 ± 1.06 D at 35° temporal visual field WC. All Proclear multifocal contact lenses (MFCLs) decreased the peripheral hyperopic defocus with increasing addition powers (F [2.938, 47.001] = 13.317, P < 0.001). However, only +3.00 D addition and +3.50 D addition (P = 0.001) could invert the peripheral hyperopic defocus into peripheral myopic defocus. Apart from that, the +3.00 D addition lens showed the lowest lag of accommodation (+1.10 ± 0.83 D) among the other MFCL adds (P = 0.002).

CONCLUSION:
A +3.00 D addition Proclear MFCL is the optimal addition power that can invert the pattern of peripheral hyperopic defocus into myopic defocus.
