Abstract
We have conducted a survey of candidate hot subdwarf (HSD) stars in the southern sky searching for fast transits, eclipses, and sinusoidal-like variability in the Evryscope light curves. The survey aims to detect transit signals from Neptune-size planets to gas giants, and eclipses from M-dwarfs and brown dwarfs. The other variability signals are primarily expected to be from compact binaries and reflection effect binaries. Due to the small size of HSDs (R ≈ 0.2 R
⊙), transit and eclipse signals are expected to last only ≈20 minutes, but with large signal depths (up to completely eclipsing if the orientation is edge on). With its 2 minute cadence and continuous observation, the Evryscope is well placed to recover these fast transits and eclipses. The very large field of view (8150 deg2) is critical to obtain enough HSD targets, despite their rarity. We identified ≈11,000 potential HSDs from the 9.3 M Evryscope light curves for sources brighter than m

g
= 15. With our machine-learning spectral classifier, we flagged high confidence targets and estimate the total HSDs in the survey to be ≈1400. The light-curve search detected three planet transit candidates, shown to have stellar companions from follow-up analysis. We discovered several new compact binaries (including two with unseen degenerate companions), two eclipsing binaries with M-dwarf companions, as well as new reflection effect binaries and others with sinusoidal-like variability. Four of the discoveries are being published in separate follow-up papers, and we discuss the follow-up potential of the other discoveries.
Modeling the IRIS Lines During a Flare. I. The Blue-wing Enhancement in the Mg II k Line
Authors: Hong Jie , Li Ying , Ding M. D. , Zhou Yu-Hao 
Published: February 2020

Abstract
The Interface Region Imaging Spectrograph (IRIS) Mg ii k line serves as a very good tool to diagnose the heating processes in solar flares. Recent studies have shown that apart from the usual red asymmetries that are interpreted as the result of condensation downflows, this line could also show a blue-wing enhancement. To investigate how such a blue asymmetry is formed, we perform a grid of radiative hydrodynamic simulations and calculate the corresponding line profiles. We find that such a spectral feature is likely to originate from the upward plasma motion in the upper chromosphere. However, the formation region that is responsible for the blue-wing enhancement could be located in an evaporation region, in an upward-moving blob, and even an upward-moving condensation region. We discuss how the electron beam parameters affect these different dynamics of the atmosphere.

Abstract
Switchbacks (rotations of the magnetic field) are observed on the Parker Solar Probe. Their evolution, content, and plasma effects are studied in this paper. The solar wind does not receive a net acceleration from switchbacks that it encountered upstream of the observation point. The typical switchback rotation angle increased with radial distance. Significant Poynting fluxes existed inside, but not outside, switchbacks, and the dependence of the Poynting flux amplitude on the switchback radial location and rotation angle is explained quantitatively as being proportional to (B sin(θ))2. The solar wind flow inside switchbacks was faster than that outside due to the frozen-in ions moving with the magnetic structure at the Alfvén speed. This energy gain results from the divergence of the Poynting flux from outside to inside the switchback, which produces a loss of electromagnetic energy on switchback entry and recovery of that energy on exit, with the lost energy appearing in the plasma flow. Switchbacks contain 0.3–10 Hz waves that may result from currents and the Kelvin–Helmholtz instability that occurs at the switchback boundaries. These waves may combine with lower frequency magnetohydrodynamic waves to heat the plasma.

Published: February 2020

Abstract
Bat (Chiroptera) assemblages in the western North America remain understudied despite their importance to ecosystem function and vulnerability to multiple anthropogenic stressors. We present the first large-scale survey that we are aware of for bat fauna in the Black Rock Plateau of northwestern Nevada in the northern Great Basin Desert. We conducted surveys using both acoustic and mist net methods, documenting 14 species across 19 sites sampled during a four-night period in August 2016. We surveyed over water sources, usually surrounded by cliff and canyon habitat, and in salt desert scrub, sagebrush, and woodland habitats, detecting multiple sensitive bat species (spotted bat Euderma maculatum, little brown bat Myotis lucifugus, canyon bat Parastrellus hesperus) in the canyon habitats of the High Rock region. We analyzed regional species diversity and present the utility of using multiple detection methods to enhance understanding of Chiroptera biodiversity at both local and regional scales. Our results demonstrate the utility of “BioBlitz” approaches in documenting local and regional diversity and provide insight into areas with species assemblages or vulnerable species. Knowledge of these sites is increasingly important for future disease surveillance and population monitoring.
Creative Juices: Sweat in Paradise Lost
Authors: Bradley Beatrice 
Published: February 2020

ABSTRACT
This article focuses on Adam's perspiration at the scene of his awakening in Paradise Lost, where immediately after his creation he finds himself “In balmy sweat.” Milton pointedly rejects the precedent of medieval scholastic writers, who excluded sweat from prelapsarian life and understood the substance as oriented toward death. Instead, Milton presents sweat as necessary to generation and linked to polymorphic birth processes in the garden. In Adam's sweaty body, Milton depicts the first man on the borders of dissolution in order to make sensible the profusion of divine love that Adam experiences in Eden. Ultimately, sweat is a marker of continuity—rather than rupture—between prelapsarian life and the fallen present.
“Till Body Up to Spirit Work”: Maimonidean Prophecy and Monistic Sublimation in Paradise Regained
Authors: Earle Philippa 
Published: February 2020

ABSTRACT
This article argues that central to understanding Paradise Regained is Milton's Hebraic monism. By amalgamating the philosophy of Maimonides on prophecy and active intellect with his own, Milton logically answers key questions which, for scholars of the poem, remain unsettled: why does the Son enter the wilderness in the first place? How does he survive here for 40 days, and how, precisely, is paradise regained? For Milton, the Son's obedience and intellectual progress effects the transmutation of his body and heightens the capacity of his active intellect. As an intellectually perfect being, the Son experiences what Maimonides terms “veridical dreams,” and this achievement is essential both to his survival and to his regaining paradise. Scholars hitherto have confined Milton's monism to Paradise Lost. This article shows that Maimonides offers new insights to the philosophy, and posits the significance of it for unlocking Paradise Regained.
A New Method for Angular Speed Measurement with Absolute Encoder
Authors: Akkaya Ramazan , Kazan Fatih Alpaslan 
Published: February 2020

The encoders are electromechanical devices that give information about the angular position and the number of turns of the shaft, which they are connected. These devices are divided into digital or analogue according to output types. On digital outputs, the output can be binary coded, gray coded or pulsed. The frequency (M) or period (T) method produces accurate results in pulse-output encoders. However, these methods alone cannot give accurate results in some encoder types, which are saw tooth type encoders that produce analogue outputs in different shapes. In this study, a new method was proposed, which reduces the relative error ratio too much below 1 % in an absolute encoder that produces an analogue output ranging from 0 V to 5 V according to the angular position of the shaft. Unlike in the studies in the literature, M method and Analog Digital Converter (ADC) were used together. Thanks to this proposed method (M + ADC), it is possible to increase the measurement accuracy of the encoders with analogue output in all speed regions.
Academic, cognitive and physical outcomes of two strategies to integrate movement in classroom: active lessons and active breaks
Authors: Méndez-Giménez A. 
Published: February 2020

El principal objetivo fue revisar la evidencia científica sobre los efectos de dos estrategias que integran movimiento en las clases de aula (clases académicas físicamente activas y descansos activos) en resultados académicos, cognitivos y de salud. Las clases físicamente activas refuerzan el contenido académico conectándolo directamente con determinadas actividades físicas, mientras que los descansos activos utilizan la AF como recuperación de la carga académica sin conectar necesariamente con contenidos curriculares. Se examinan las revisiones y meta-análisis publicadas en los últimos cinco años y se pone el foco en implicaciones docentes relevantes. Se concluye que integrar movimiento en las clases académicas tiene el potencial no solo de mejorar los niveles de actividad física modera y vigorosa de los estudiantes durante la jornada escolar, sino también de incrementar facilitadores del aprendizaje como la concentración, la cognición y el tiempo en la tarea, así como las funciones ejecutivas de organización, y el rendimiento académico.
The main objective was to review the scientific evidence about the effects of two strategies that integrate movement in classroom lessons (physically active academic lesson and active brakes) on academic, cognitive and health outcomes. Physically active lessons reinforce academic contents by directly connecting them with certain physical activities, while active breaks use physical activity as a recovery from the academic load without necessarily connect with curricular contents. Systematic reviews and meta-analysis published in the last five years are examined and the focus is on relevant teaching implications. It is concluded that integrating movement in academic lessons has the potential not only to improve levels of students´ moderate and vigorous physical activity during school day, but also to increase learning facilitators such as concentration, cognition and time on task, as well as the executive functions of organization, and academic performance.
Effects of Intermittent Calf Muscle Electrical Stimulation on Walking Capacity in Claudicants Living with Type 2 Diabetes
Authors: Ellul Christian , Formosa Cynthia , Gatt Alfred 
Published: February 2020

Background:
First-line therapy for diabetic patients presenting with intermittent claudication includes supervised exercise programs to improve walking distance. However, exercise comes with a variety of barriers and may be contraindicated in certain conditions. The aim of this study was to evaluate whether calf muscle electrostimulation improves claudication distance.

Methods:
A prospective, one-group, pretest-posttest study design was used on 40 participants living with type 2 diabetes mellitus, peripheral artery disease (ankle brachial pressure index, <0.90), and calf muscle claudication. Calf muscle electrostimulation of varying frequencies (1–250 Hz) was prescribed on both limbs for 1-hour daily sessions for 12 consecutive weeks. The absolute claudication distance (ACD) was measured at baseline and after the intervention.

Results:
The recruited cohort (30 men and ten women; mean age, 71 years; mean ankle brachial pressure index, 0.70) registered a mean ± SD baseline ACD of 333.71 ± 208 m. After a mean ± SD of 91.68 ± 6.23 days of electrical stimulation, a significant mean ± SD increase of 137 ± 136 m in the ACD (P = .001, Wilcoxon signed rank test) was registered. Improvement was found to be sex independent, but age was negatively correlated with proportion of improvement (r = –0.361; P = .011, Pearson correlation test).

Conclusions:
Electrical stimulation of varying frequencies on ischemic calf muscles significantly increased the maximal walking capacity in claudicants with type 2 diabetes. This therapeutic approach should be considered in patients with impaired exercise tolerance or as an adjunct treatment modality.

Aims: Across the globe, outsourcing services has become more complex and sophisticated. The aim of this study is to establish the level of satisfaction of Nigerian construction firms on outsourced services at construction phase of building with a view to assisting construction firms in their decision on whether to outsourced a particular work section or not.
Study Design: Survey Research Design.
Place and Duration of Study: The study took place in Ogun State, Nigeria, between June 2019 and December 2019.
Methodology: The study focused on outsourcing and targeted at outsourcing services offered during construction phase of building. The research combined a wide-ranging literature review and questionnaire survey. A well-structured questionnaire was designed and distributed to construction firms in Ogun state. A total of 73 of the survey questionnaires were administered out of which 47 representing 64.4% were adequately filled and returned. Data obtained were analysed using frequency, percentage, mean, relative importance index and ranking.
Results: Findings from the study revealed that piling is the most often outsourced work during construction phase of building, followed by electrical installation, cladding and mechanical installation. The results of the study revealed major reasons for outsourcing to include specialization, technology advancement and core competences. Ability to meet changing needs, service-level contract agreement with outsourcer and excessive dependence on vendor reliability were revealed to be the major challenges that affect the ability of the Nigerian construction firms to successfully outsource services. It was also established that Nigerian construction firms have high level of satisfaction on the outsourced services during the construction phase of building.
Conclusion: The study suggested that Nigerian construction firms should give consideration to piling, cladding, basement and mechanical installation in outsourcing and concreting, formwork, plumbing installation and roofing in in-house.

Published: February 2020

AbstractAlong with the increasing aggravation of energy and environmental problems, the demand and utilization of renewable energy have increased. The rational design of advanced functional materials serves as a critical point for the improvement of performance and the practical application in renewable energy devices. Layered double hydroxides (LDHs) with 2D layered structures are promising energy materials for their unique physical and chemical properties. Nevertheless, the applications are limited by the structure of stacking with irrational electronic structure, sluggish mass transfer, and low activity. The exfoliation of LDHs into single‐ or few‐layered nanosheets appears to be a promising approach to overcome the above disadvantages. Herein, the recent progress on the development of exfoliation strategies for LDHs including liquid phase exfoliation, plasma‐induced exfoliation, and other advanced exfoliation strategies is highlighted and the applications in energy conversion and storage are systematically introduced.
Interfacial and Bulk Magnetic Properties of Stoichiometric Cerium Doped Terbium Iron Garnet Polycrystalline Thin Films

Published: February 2020

AbstractOne of the best magneto‐optical claddings for optical isolators in photonic integrated circuits is sputter deposited cerium‐doped terbium iron garnet (Ce:TbIG) which has a large Faraday rotation (≈−3500° cm−1 at 1550 nm). Near‐ideal stoichiometry of Ce0.5Tb2.5Fe4.75O12 is found to have a 44 nm magnetic dead layer that can impede the interaction of propagating modes with garnet claddings. The effective anisotropy of Ce:TbIG on Si is also important, but calculations using bulk thermal mismatch overestimate the effective anisotropy. Here, X‐ray diffraction measurements yield highly accurate measurements of strain that show anisotropy favors an in‐plane magnetization in agreement with the positive magnetostriction of Ce:TbIG. Upon doping TbIG with Ce, a slight decrease in compensation temperature occurs which points to preferential rare‐earth occupation in dodecahedral sites and an absence of cation redistribution between different lattice sites. The high Faraday rotation, large remanent ratio, large coercivity, and preferential in‐plane magnetization enable Ce:TbIG to be an in‐plane latched garnet, immune to stray fields with magnetization collinear to direction of light propagation.

Published: February 2020

AbstractWithin the framework of stochastic reactive molecular dynamics simulations a statistical method for generating fluorinated graphene structures with desirable fluorine distribution is developed. Electronic transport properties of fluorinated graphene in a wide range of functionalization degrees and system ordering are investigated. A strong correlation between irregularities in fluorine distribution and electronic properties is found. In particular, proposed consideration allows for the reproduction of both the experimentally observed electron–hole asymmetry in transport properties of fluorinated graphene and a recently revealed conductivity peak at 10% fluoride content.
