Аналіз асортименту рослин оранжереї ботанічного саду "Поділля" Вінницького Національного аграрного університету
Authors: Монарх В. В. 
Published: May 2020

Доведено, що місцем, відведеним під озеленення приміщення, в якому на обмеженій площі розміщено екзотичні рослини в поєднанні з водними пристроями та малими архітектурними формами, є оранжерея ботанічного саду "Поділля" Вінницького національного аграрного університету. Її основне призначення є не тільки естетичне задоволення гостей та жителів міста, відпочинок на природі в будь-який сезон року, а й розмноження та інтродукція видів рослин інших кліматичних зон. Вперше проведено сучасну оцінку асортименту рослин оранжереї ботанічного саду "Поділля" ВНАУ, відповідно до якої в оранжереї нараховують 44 родини, 88 родів та 94 види рослин. Висвітлено, що головним компонентом оранжереї є види, що належать до різних родин та відрізняються за вимогами, необхідними для їх росту та розвитку. Асортимент видів, представлених в оранжереї, є надзвичайно широкий. Встановлено, що рослини за вимогами до місцезростання належать до різних кліматичних зон. Тому для їх декоративності та відмінного росту в оранжереї необхідним є створення відповідним умов. Досліджено, що рослини різних природних ареалів зростання розташовані в оранжереї хаотично без дотримання певного порядку чи систематики. Види інтродуцентів, які є в оранжереї ботанічного саду різняться за відношенням до температури, прийнятної для їх нормального росту і розвитку, тому і розміщувати їх варто групами чи колекціями, наприклад: зона рослин тропіків, зона рослин субтропіків, зона рослин сухих субтропіків, зона рослин Середземномор'я та зона рослин Азії. Враховуючи встановлену малу кількість представників рослин сухих субтропіків в оранжереї ботанічного саду, обов'язковим є поповнення колекції сукулентів та створення флораріуму і кактусарію.

Authors: Караванович Х. Б. , Глібовицька Н. І. 
Published: May 2020

Досліджено особливості акумуляції хімічних елементів деревними рослинами в умовах впливу Битків-Бабчинського нафтового родовища. Рентгенофлуоресцентним методом встановлено концентрацію алюмінію, цинку, титану, феруму, стронцію, нікелю, купруму, арсену, брому, рубідію, молібдену, паладію, аргентуму, плюмбуму, ванадію у сухій масі листкових пластинок клена гостролистого, бука лісового, ліщини звичайної, берези повислої, липи серцелистої та осики, що зростають у забрудненому нафтопродуктами довкіллі. За допомогою програм CorelDRAW та ImageJ розраховано частку некротизованої тканини асиміляційних органів деревних рослин в умовах впливу родовища. Встановлено прямо пропорційну залежність між ураженням листкових пластинок дерев некрозами та накопиченням хімічних елементів рослинами. Зафіксовано відсутність арсену, брому, молібдену, паладію, аргентуму, плюмбуму, ванадію у листках клена, бука, липи. Виявлено зростання вмісту хімічних елементів у асиміляційних органах дослідних дерев у такому ряді: Mo → Pb → Pd → Ag → Br → As → V → Ni → Rb → Cu → Sr → Ti → Zn → Fe → Al. Частка некротизації листків в умовах Битків-Бабчинського нафтового родовища зростає у ряді дослідних рослин: бук → клен → липа → осика → береза → ліщина. Максимальною акумулятивною здатністю хімічних елементів володіє ліщина, мінімальною – бук та клен. Враховуючи значні кумулятивні ресурси ліщини, доцільно використовувати вид як фіторемедіант забрудненого хімічними елементами довкілля. Клен та бук належать до рослин-елімінаторів, які вибірково та в невеликих кількостях поглинають токсиканти з довкілля, що зумовлено наявністю у цих видів потужних протекторних механізмів. Береза, липа та осика відзначаються цінними біоіндикаторними характеристиками та їх можна використовувати для оцінювання екологічного напруження середовища.
Функционирование русскоязычного интертекста в переводе: лингвоаксиология перевода постмодернистского текста
Authors: Karpukhina V.N. 
Published: May 2020

Основная задача статьи выявить ключевые лингвоаксиологические стратегии переводческого дискурса при передаче постмодернистского текста с русского языка на английский. В результате исследования было определено, что русскоязычный интертекст романа Бориса Акунина ориентирован на максимальное узнавание массовой аудиторией. Однако за легко опознаваемыми интертекстуальными элементами романа скрывается двойная ирония автора ирассказчика в тексте, что создает специфические аксио-генные ситуации переоценки текстов русской классической литературы. Эндрю Бромфильд, переводчик романа Акунина на английский язык, адекватно воссоздает прагматический потенциал иронических отсылок интертекста. Аксиогенные ситуации иронического использования сюжетных ходов русских модернистских текстов вромане Акунина при переводе остаются в пространстве затекстовой информации.The paper considers precedent text creating Russian intertext in the novelThe Diamond Chariotby Boris Akunin and its translation into English. The object under consideration is intertextual allusions, both in the original and in translation of the novel. The subject analyzed is the postmodernist translators discourse. The paper aims at revealing the key axiological linguistic strategies used in translation of the postmodernist text from Russian into English. The research resulted in the fact that Russian intertext of Boris Akunins novel is made for being understandable by mass audience. But the authors and narrators irony lies beneath those recognizable intertextual elements which create specific axiogenic situations of re-evaluation Russian classic literature texts. Andrew Bromfield, the translator of Akunins novel into English, reconstructs adequately the pragmatic potential of intertextual ironic allusions. Axiogenic situations of ironic usage of Russian modernist texts plots in Akunins novel go behind the scene in translation.

Published: May 2020

Abstract
We use the second Gaia data release (Gaia DR2), combined with Radial Velocity Experiment spectroscopic surveys, to identify the substructures in the nearby stellar halo. We select 3845 halo stars kinematically and chemically and determine their density distribution in energy and angular momentum space. To select the substructures from overdensities, we reshuffle the velocities and estimate their significance. Two statistically significant substructures, GR-1 and GR-2, are identified. GR-1 has a high binding energy and small z-angular momentum. GR-2 is metal-rich but retrograde. They are both new substructures, and may be accretion debris of dwarf galaxies.
Studying the Local Magnetic Field and Anisotropy of Magnetic Turbulence by Synchrotron Polarization Derivative
Authors: Zhang Jian-Fu , Hu Ke , Cho Jungyeon , Lazarian Alex 
Published: May 2020

Abstract
Due to the inevitable accumulation of observational information in the direction of the line of sight, it is difficult to measure the local magnetic field of magnetohydrodynamic (MHD) turbulence. However, a correct understanding of the local magnetic field is a prerequisite for reconstructing the Galactic 3D magnetic field. We study how to reveal the local magnetic field direction and the eddy anisotropy on the basis of the statistics of synchrotron polarization derivative with respect to the squared wavelength dP/dλ
2. In the low-frequency and strong Faraday rotation regime, we implement numerical simulations in the combination of multiple statistic techniques, such as structure function, quadrupole ratio modulus, spectral correlation function, correlation function anisotropy, and spatial gradient techniques. We find that (1) statistic analysis of dP/dλ
2 indeed reveals the anisotropy of underlying MHD turbulence, the degree of which increases with the increase of the radiation frequency; and (2) the synergy of both correlation function anisotropy and gradient calculation of dP/dλ
2 enables the measurement of the local magnetic field direction.
Oceanographic Considerations for Exoplanet Life Detection
Authors: Olson Stephanie L. , Jansen Malte , Abbot Dorian S. 
Published: May 2020

Abstract
Liquid water oceans are at the center of our search for life on exoplanets because water is a strict requirement for life as we know it. However, oceans are dynamic habitats—and some oceans may be better hosts for life than others. In Earth’s ocean, circulation transports essential nutrients such as phosphate and is a first-order control on the distribution and productivity of life. Of particular importance is upward flow from the dark depths of the ocean in response to wind-driven divergence in surface layers. This “upwelling” returns essential nutrients that tend to accumulate at depth via sinking of organic particulates back to the sunlit regions where photosynthetic life thrives. Ocean dynamics are likely to impose constraints on the activity and atmospheric expression of photosynthetic life in exo-oceans as well, but we lack an understanding of how ocean dynamics may differ on other planets. We address this issue by exploring the sensitivity of ocean dynamics to a suite of planetary parameters using ROCKE-3D, a fully coupled ocean–atmosphere general circulation model. Our results suggest that planets that rotate slower and have higher surface pressure than Earth may be the most attractive targets for remote life detection because upwelling is enhanced under these conditions, resulting in greater nutrient supply to the surface biosphere. Seasonal deepening of the mixed layer on high-obliquity planets may also enhance nutrient replenishment from depth into the surface mixed layer. Efficient nutrient recycling favors greater biological activity, more biosignature production, and thus more detectable life. More generally, our results demonstrate the importance of considering oceanographic phenomena for exoplanet life detection and motivate future interdisciplinary contributions to the emerging field of exo-oceanography.
Electric Current Evolution at the Footpoints of Solar Eruptions
Authors: Barczynski Krzysztof , Aulanier Guillaume , Janvier Miho , Schmieder Brigitte , Masson Sophie 
Published: May 2020

Abstract
Electric currents play a critical role in the triggering of solar flares and their evolution. The aim of the present paper is to test whether the surface electric current has a surface or subsurface fixed source as predicted by the circuit approach of flare physics, or is the response of the surface magnetic field to the evolution of the coronal magnetic field as the MHD approach proposes? Out of all 19 X-class flares observed by SDO from 2011 to 2016 near the disk center, we analyzed the only nine eruptive flares for which clear ribbon hooks were identifiable. Flare ribbons with hooks are considered to be the footprints of eruptive flux ropes in MHD flare models. For the first time, fine measurements of the time evolution of electric currents inside the hooks in the observations as well as in the OHM 3D MHD simulation are performed. Our analysis shows a decrease of the electric current in the area surrounded by the ribbon hooks during and after the eruption. We interpret the decrease of the electric currents as due to the expansion of the flux rope in the corona during the eruption. Our analysis brings a new contribution to the standard flare model in 3D.
The Angular Momentum of the Circumgalactic Medium in the TNG100 Simulation

Published: May 2020

Abstract
We present an analysis of the angular momentum content of the circumgalactic medium (CGM) using TNG100, one of the flagship runs of the IllustrisTNG project. We focus on Milky Way–mass halos (∼1012
M
⊙) at z = 0 but also analyze other masses and redshifts up to z = 5. We find that the CGM angular momentum properties are strongly correlated with the stellar angular momentum of the corresponding galaxy: the CGM surrounding high-angular momentum galaxies has a systematically higher angular momentum and is better aligned to the rotational axis of the galaxy itself than the CGM surrounding low-angular momentum galaxies. Both the hot and cold phases of the CGM show this dichotomy, though it is stronger for colder gas. The CGM of high-angular momentum galaxies is characterized by a large wedge of cold gas with rotational velocities at least ∼1/2 of the halo’s virial velocity, extending out to ∼1/2 of the virial radius, and by biconical polar regions dominated by radial velocities suggestive of galactic fountains; both of these features are absent from the CGM of low-angular momentum galaxies. These conclusions are general to halo masses ≲1012
M
⊙ and for z ≲ 2, but they do not apply for more massive halos or at the highest redshift studied. By comparing simulations run with alterations to the fiducial feedback model, we identify the better alignment of the CGM to high-angular momentum galaxies as a feedback-independent effect and the galactic winds as a dominant influence on the CGM’s angular momentum.
The Rotation Curve, Mass Distribution, and Dark Matter Content of the Milky Way from Classical Cepheids
Authors: Ablimit Iminhaji , Zhao Gang , Flynn Chris , Bird Sarah A. 
Published: May 2020

Abstract
With the increasing number of large stellar survey projects, the quality and quantity of excellent tracers for studying the Milky Way are rapidly growing, one of which is the classical Cepheids. Classical Cepheids are high-precision standard candles with very low typical uncertainties (<3%) available via the mid-infrared period–luminosity relation. About 3500 classical Cepheids identified from the Optical Gravitational Lensing Experiment, All-Sky Automated Survey for Supernova, Gaia, Wide-field Infrared Survey Explorer, and Zwicky Transient Facility survey data have been analyzed in this work, and their spatial distributions show a clear signature of Galactic warp. Two kinematical methods are adopted to measure the Galactic rotation curve (RC) in the Galactocentric distance range of

. Gently declining RCs are derived by both the proper motion (PM) method and three-dimensional velocity vector (3DV) method. The largest sample of classical Cepheids with the most accurate 6D phase-space coordinates available to date are modeled in the 3DV method, and the resulting RC is found to decline at the relatively smaller gradient of (−1.33 ± 0.1)

. Comparing to results from the PM method, a higher rotation velocity ((232.5 ± 0.83)

) is derived at the position of the Sun in the 3DV method. The virial mass and local dark matter density are estimated from the 3DV method, which is the more reliable method,

and

GeV, respectively.
The Chiral Puzzle of Life
Authors: Globus Noemie , Blandford Roger D. 
Published: May 2020

Abstract
Biological molecules chose one of two structurally chiral systems which are related by reflection in a mirror. It is proposed that this choice was made, causally, by cosmic rays, which are known to play a major role in mutagenesis. It is shown that magnetically polarized cosmic rays that dominate at ground level today can impose a small, but persistent, chiral bias in the rate at which they induce structural changes in simple, chiral monomers that are the building blocks of biopolymers. A much larger effect should be present with helical biopolymers, in particular, those that may have been the progenitors of ribonucleic acid and deoxyribonucleic acid. It is shown that the interaction can be both electrostatic, just involving the molecular electric field, and electromagnetic, also involving a magnetic field. It is argued that this bias can lead to the emergence of a single, chiral life form over an evolutionary timescale. If this mechanism dominates, then the handedness of living systems should be universal. Experiments are proposed to assess the efficacy of this process.
Stochastic Turbulent Acceleration in a Fractal Environment
Authors: Sioulas Nikos , Isliker Heinz , Vlahos Loukas 
Published: May 2020

Abstract
We analyze the stochastic acceleration of particles inside a fully developed turbulent plasma. It is well known that large-amplitude magnetic fluctuations and coherent structures in such an environment obey a fractal scaling, and our specific aim is to study for the first time the effects of the fractality of these environments on stochastic acceleration. We have shown that an injected Maxwellian energy distribution is heated and forms a high-energy tail in a very short time. Using standard parameters for the low solar corona, the injected Maxwellian distribution of electrons gets heated from the initial 100 eV to 10 KeV, and the power-law index of the high-energy tail is about −2.3. The high-energy tail starts around 100 keV, and reaches 10 MeV. The index of the power-law tail depends on the system size, and it is in good agreement with observed values for realistic system sizes. The heating and acceleration process is very fast (∼2 s). The reason why the acceleration time is so short is that the particles are trapped within small-scale parts of the fractal environment, and their scattering mean free path reduces drastically. The presence of small-scale activity also easily pulls particles from the thermal pool, so there is no need for a seed population. The mean square displacement in space and energy is superdiffusive for the high-energy particles.

Abstract
In 2018, the near-Earth object (155140) 2005 UD (hereafter UD) experienced a close fly by of the Earth. We present results from an observational campaign involving photometric, spectroscopic, and polarimetric observations carried out across a wide range of phase angles (0.°7–88°). We also analyze archival NEOWISE observations. We report an absolute magnitude of H
V = 17.51 ± 0.02 mag and an albedo of p
V = 0.10 ± 0.02. UD has been dynamically linked to Phaethon due their similar orbital configurations. Assuming similar surface properties, we derived new estimates for the diameters of Phaethon and UD of D = 5.4 ± 0.5 km and D = 1.3 ± 0.1 km, respectively. Thermophysical modeling of NEOWISE data suggests a surface thermal inertia of

and regolith grain size in the range of 0.9–10 mm for UD and grain sizes of 3–30 mm for Phaethon. The light curve of UD displays a symmetric shape with a reduced amplitude of Am(0) = 0.29 mag and increasing at a linear rate of 0.017 mag/° between phase angles of 0° and ∼25°. Little variation in light-curve morphology was observed throughout the apparition. Using light-curve inversion techniques, we obtained a sidereal rotation period P = 5.235 ± 0.005 hr. A search for rotational variation in spectroscopic and polarimetric properties yielded negative results within observational uncertainties of ∼10% μm−1 and ∼16%, respectively. In this work, we present new evidence that Phaethon and UD are similar in composition and surface properties, strengthening the arguments for a genetic relationship between these two objects.

Published: May 2020

<p class="0abstract">Computing and measuring the total capacity of a data network are a remarkably difficult problem. These metrics are directly linked to the available bandwidth to each wireless internet of things (IoT) device of the network. In this paper, the authors study the performance metrics associated with capacity traffic in multi-hop wireless mesh networks (WMNs). It is dedicated to Internet access assuming a time division multiple access (TDMA). They focus simultaneously on three key operating metrics, the total network capacity (TNC), total application network capacity (TANC), and the Average message time (AMS). They also analyze how parameters such as forward error correction (FEC) and acknowledgments (ACK) affect the overall network capacity under different operating conditions. Theoretical network capacity for WMNs, in this paper, is explored to draw attention to the number of open research issues</p>
Health-Related Quality of Life Among Middle-Aged Adults With Chronic Ankle Instability, Copers, and Uninjured Controls
Authors: Kosik Kyle B. , Johnson Nathan F. , Terada Masafumi , Thomas-Fenwick Abbey C. , Mattacola Carl G. , Gribble Phillip A. 
Published: May 2020

Context
People with chronic ankle instability (CAI) display a lower regional and global health-related quality of life (HRQoL). Examinations of HRQoL outcomes associated with CAI have addressed younger adults, restricting our understanding of the long-term consequences of CAI.

Objective
To compare ankle regional and global HRQoL in middle-aged participants with and those without CAI.

Design
Cross-sectional study.

Setting
Laboratory.

Patients or Other Participants
A total of 59 middle-aged volunteers, consisting of 18 with CAI (age = 50.2 ± 9.3 years), 17 who were ankle-sprain copers (age = 54.5 ± 8.7 years), and 24 uninjured controls (age = 56.7 ± 10.0 years).

Main Outcome Measure(s)
Participants completed the Foot and Ankle Disability Index (FADI) and the Patient-Reported Outcomes Measurement Information System Adult Profile. Regional HRQoL was assessed using the FADI Activities of Daily Living and Sport subscales. Global HRQoL was measured using the 43-item Patient-Reported Outcomes Measurement Information System Adult Profile, which contains 7 short forms—Physical Function, Pain Interference, Fatigue, Depression, Sleep Disturbance, Anxiety, and Ability to Participate in Social Roles and Activities. Separate Kruskal-Wallis tests were used to determine between-groups differences.

Results
Middle-aged participants with CAI had lower scores on both subscales of the FADI than the coper and control groups (all P values &lt;.001). Participants with CAI scored lower on the Physical Function (U = 116.0, z = −2.78, P = .005) and Ability to Participate in Social Roles and Activities (U = 96.0, z = −3.09, P = .002) subscales but higher on the Pain Interference (U = 144.0, z = −2.36, P = .02), Fatigue (U = 110.0, z = −2.72, P = .006), and Depression (U = 110.5, z = −2.91, P = .004) subscales than the control group. Participants with CAI also scored lower on the Physical Function (U = 74.5, z = −2.79, P = .005) and Ability to Participate in Social Roles and Activities (U = 55.0, z = −3.29, P = .001) subscales but higher on the Fatigue (U = 90.0, z = −2.09, P = .04) and Depression (U = 96.5, z = −1.97, P = .048) subscales than the coper group.

Conclusions
Middle-aged participants with CAI displayed worse ankle regional and global HRQoL than their age-matched healthy counterparts and copers. These results demonstrated that CAI can affect HRQoL outcomes in middle-aged adults.
