Abstract
The recent detection of circularly polarized, long-duration (>8 hr), low-frequency (∼150 MHz) radio emission from the M4.5 dwarf GJ 1151 has been interpreted as arising from a star–planet interaction via the electron cyclotron maser instability. The existence or parameters of the proposed planets have not been determined. Using 20 new HARPS-N observations, we put 99th-percentile upper limits on the mass of any close companion to GJ 1151 at

. With no stellar, brown dwarf, or giant planet companion likely in a close orbit, our data are consistent with detected radio emission emerging from a magnetic interaction between a short-period terrestrial-mass planet and GJ 1151 (https://github.com/benjaminpope/video).

Namen prispevka je poskus vrednotenja družbenega vidika trajnostnega razvoja Velenja, ki v evropskem merilu sodi med mala industrijska mesta. Pri vrednotenju smo uporabili v tujini uveljavljeno orodje Social Sustainability Framework in ga prilagodili lokalnemu kontekstu. Ugotovili smo, da je Velenje mesto z visoko stopnjo družbene trajnostnosti v treh od štirih ocenjenih sklopov: dobrin in družbene infrastrukture, družbenega in kulturnega življenja ter vpliva, ki ga ima lokalno prebivalstvo na razvoj. Največja slabost mesta je slabša prilagodljivost in prožnost kot posledica na dveh večjih podjetjih temelječega gospodarstva. Ocenjujemo, da ima uporabljeno orodje veliko uporabno vrednost za urbano načrtovanje in urbani razvoj. //

The purpose of the article was to evaluate the social sustainability of Velenje, which falls into the category of small industrial towns on the European scale. The evaluation was done by using Social Sustainability Framework, an established tool that was adjusted to the local context. It was determined that Velenje is a town with a high level of social sustainability both in the areas of goods and social infrastructure, social and cultural life, as well as the influence that the local inhabitants have on development. The town’s greatest disadvantage is its reduced adaptability level and flexibility, which is the consequence of an economy based on only two major companies. We believe that the tool has the potential to be useful for urban planning and development.

Preučevanje intenzivnosti erozijskih procesov spada med temeljne in pogosto obravnavane geomorfološke dejavnosti ter običajno vključuje tako terenske meritve kot tudi računalniško modeliranje. V Sloveniji so terenske meritve redke, zato prevladuje modeliranje erozijskih procesov. Pri slednjem je zaradi svoje preprostosti kljub pomanjkljivostim zelo priljubljena Gavrilovićeva enačba v več različicah. V prispevku predstavljamo uporabnost geografskih informacijskih sistemov pri izračunu posameznih členov Gavrilovićeve enačbe. Z njeno pomočjo smo za panonska gričevja severovzhodne Slovenije ocenili intenzivnost erozije. //

The study of the intensity of erosion processes is one of the fundamental and often treated geomorphological activities. It usually involves both field measurements, as well as computer modelling. In Slovenia, field measurements are rare, so modelling of erosion processes prevail. Due to its simplicity the Gavrilović equation (and its derivatives) is very popular for the calculations of erosion; despite its shortcomings. The paper presents the usefulness of geographic information systems in the calculation of individual parameters of Gavrilović equation. The Gavrilović equation was used to calculate the intensity of erosion in Pannonian low-hills of north-eastern Slovenia.
Origin of the residual line width under frequency-switched Lee–Goldburg decoupling in MAS solid-state NMR

Published: February 2020

Abstract. Homonuclear decoupling sequences in solid-state nuclear magnetic resonance (NMR) under
magic-angle spinning (MAS) show experimentally significantly larger residual
line width than expected from Floquet theory to second order. We present an
in-depth theoretical and experimental analysis of the origin of the residual
line width under decoupling
based on frequency-switched Lee–Goldburg (FSLG) sequences. We analyze the effect of experimental pulse-shape errors (e.g., pulse
transients and B1-field inhomogeneities) and use a Floquet-theory-based
description of higher-order error terms that arise from the interference
between the MAS rotation and the pulse sequence. It is shown that the
magnitude of the third-order auto term of a single homo- or heteronuclear
coupled spin pair is important and leads to significant line broadening
under FSLG decoupling. Furthermore, we show the dependence of these
third-order error terms on the angle of the effective field with the
B0 field. An analysis of second-order cross terms is presented that
shows that the influence of three-spin terms is small since they are
averaged by the pulse sequence. The importance of the inhomogeneity of the radio-frequency (rf) field
is discussed and shown to be the main source of residual line broadening
while pulse transients do not seem to play an important role.
Experimentally, the influence of the combination of these error terms is
shown by using restricted samples and pulse-transient compensation. The
results show that all terms are additive but the major contribution to the
residual line width comes from the rf-field inhomogeneity for the standard
implementation of FSLG sequences, which is significant even for samples with
a restricted volume.
Raphael's Homeric and Biblical Metamorphosis
Authors: Adkins David 
Published: February 2020

ABSTRACT
Why does Raphael metamorphose in his descent to Eden, and why does Milton initially disguise the metamorphosis as a simile? Though the episode is traditionally considered more Virgilian than Homeric, it is its Homeric dimension that answers these questions. Milton intervenes, I suggest, in the ancient debate on whether Hermes transforms into or merely descends like a gull. But by suggesting and then correcting the simile-reading, Milton also instructs his readers not to read the Bible's metamorphoses like Calvin, whose hermeneutics often resemble those of pagan grammarians, particularly those who read Hermes's likeness to the bird figuratively. By exploring the debates on two descents, that of Hermes and that of the Holy Spirit in the Gospels, I demonstrate how Milton employs Homeric imitation to contest Calvin's theory of accommodation and to present history as more marvelous than myth.
Milton's Chivalric Tragedy: The Persistence of Romance in Book 9 of Paradise Lost
Authors: Cook Trevor 
Published: February 2020

ABSTRACT
Milton's most consequential statement regarding his plans for an Arthurian epic occurs in the proem to book 9 of Paradise Lost, in which he seemingly refuses to debase his current project with the trivialities of chivalric romance. His loftier subject will instead be the tragedy of Adam and Eve. Milton's account of the Fall is obviously a Christian tragedy with classical precedents. However, judging by the frequency with which it follows romance conventions, book 9 of Paradise Lost can also be read as a chivalric tragedy, a mode not only familiar to Milton's contemporaries but also well suited to his political agenda and lifelong fondness for Arthurian literature. In fact, the proem does not reject romance outright, only a particular model associated with royalist propaganda. Its purpose is instead to prepare the reader, in true romance fashion, for the hero's choice between the genre's more superficial trappings and the righteous quests of the truly chivalrous.
Similarity, Attraction, and Compromise Effects: Original Findings, Recent Empirical Observations, and Computational Cognitive Process Models
Authors: Wollschlaeger Lena M. , Diederich Adele 
Published: February 2020

Abstract
Preference reversals—a decision maker prefers A over B in one situation but B over A in another—demonstrate that human behavior violates invariance assumptions of (utility-based) rational choice theories. In the field of multi-alternative multi-attribute decision-making research, 3 preference reversals received special attention: similarity, attraction, and compromise effects. The 3 so-called context effects are changes in (relative) choice probabilities for 2 choice alternatives after a third “decoy” option is added to the set. Despite their simplicity, the effects demonstrate that choice probabilities in multi-alternative decision making are contingent on the local context, that is, on the choice set under consideration. Because of their simplicity, on the other hand, similarity, attraction, and compromise effects have been successfully examined in numerous studies to date, and they have become of increasing interest for differentiating between computational cognitive process models of multi-alternative multi-attribute decision making. However, the stimulus arrangement for producing the effects seems to vary between studies, which becomes challenging when model accounts are compared. The purpose of this review is to present various paradigms in a coherent way and describe various model accounts based on a common structure.

El objetivo del presente estudio fue conocer la tipología de los goles marcados en el fútbol profesional español mediante un análisis observacional. Los 1137 goles (508 en Primera división y 629 Segunda división) marcados en los 421 partidos de fútbol correspondientes a la temporada 2017-2018 en Primera y Segunda división fueron analizados. Todos los goles se clasificaron en función de su tipología. De manera general, la mayoría de los goles se anotaron con las extremidades inferiores, al primer toque y desde dentro del área. No se obtuvieron diferencias significativas (p > 0,05) al comparar la tipología de los goles en función de la categoría de la competición. Sin embargo, se observaron diferencias significativas (p < 0,05) al comparar los diferentes puestos específicos. Los resultados obtenidos sugieren que se deben plantear tareas de entrenamiento específicas, en función del puesto específico, con el fin de optimizar el rendimiento de cara a gol de los futbolistas.
The aim of the present investigation was to know the typology of the goals scored in Spanish professional soccer through an observational analysis. 1137 goals (508 First division and 629 Second division) scored in 421 soccer matches corresponding to the 2017-2018 season in First and Second division were analyzed. All the goals were classified according to their typology. In general, most of the goals were scored with the legs, at the first touch and from within the area. No significant differences were obtained (p> 0.05) when comparing the typology of goals according to the category of the competition. However, significant differences were observed (p <0.05) when comparing the different playing positions. The results obtained suggest that specific training tasks should be proposed, depending on the playing position, in order to optimize the performance of the players' goal.

Aims: The study examined the impact of insurance sector development on foreign direct investment in Nigeria.
Study Design: The ex-post facto research design was employed to observe the study components in retrospect. Secondary data spanning 1996 to 2017 was sourced and collated from the World Development Indicators, Central Bank of Nigeria statistical bulletin and National Insurance Commission annual balance sheets.
Place and Duration of Study: Department of Banking and Finance, Niger Delta University, Wilberforce Island, Bayelsa State, Nigeria. The study was carried out between November 2019 to January 2020.
Methodology: The ex-post facto research design was employed to observe the study components in retrospect. Secondary data spanning 1996 to 2017 was sourced and collated from the World Development Indicators, Central Bank of Nigeria statistical bulletin and National Insurance Commission annual balance sheets. The time series data was estimated using the least square technique.
Results: The results indicates that; the total asset size of the insurance sector exerts a negative and statistically insignificant impact on foreign direct investment inflow to Nigeria, total insurance business investment exerts a positive and statistically insignificant impact on foreign direct investment inflow to Nigeria and finally, total insurance premium exerts a negative and statistically significant impact on foreign direct investment inflow to Nigeria.
Conclusion: The study concludes that insurance sector development does not attract foreign investment inflow to Nigeria. The study recommends that the insurance sector should be revamped in order to absorb risk and uncertainty and be a vehicle for risk transfer and minimization. A policy of restructuring would help instil public confidence, boost insurance policy sales, increase insurance premium and invariably increase the availability of investible funds to boost economic activity. The study suggests that these would help attract foreign direct investment to meet domestic funding needs of Nigeria.

Published: February 2020

AbstractObstructive jaundice caused by metastasis of lung cancer to distal common bile duct (CBD) is extremely rare. Here, we report a 70‐year‐old man presented with progressive jaundice and generalized weakness for 1 month. He had a medical history of stage IIB (pT2N1M0) lung adenocarcinoma, for which he had undergone surgical treatment and subsequent adjuvant chemotherapy 3 years ago. Endoscopic retrograde cholangiopancreatography (ERCP) revealed a distal CBD stricture. Histopathological examination of the biopsy specimen taken from the stricture site demonstrated adenocarcinoma with positive for cytokeratin‐7 and thyroid transcription factor‐1 on immunohistochemistry. The findings confirmed the diagnosis of metastasis of recurrent lung adenocarcinoma to the CBD. The patient's jaundice improved after insertion of an endoscopic retrograde bile duct (ERBD) drainage plastic stent at the time of ERCP. He was then started on target therapy with afatinib after discharge. The ERBD stent was removed 3 months later. He had remained in stable condition without jaundice during the 1‐year follow‐up period. In conclusion, obstructive jaundice caused by metastatic adenocarcinoma to the CBD is a rare manifestation of lung cancer. An accurate diagnosis is crucial in further treatment for such a patient.
Designing real time model mobile monitoring system for model predictive control in a nonlinear continuous stirred tank reactor
Authors: Djarum Danny Hartanto , Ahmad Zainal 
Published: February 2020

AbstractA continuous stirred tank reactor (CSTR) plays a major role in many process industries, and its control strategy could be very critical in achieving desirable yields, conversion, rates, and minimizing the formation of side products. CSTR control over a wide operating range has been a major issue to control engineers as it exhibits a highly nonlinear behaviour and time varying behaviour. A traditional control mechanism like a proportional–integral–derivative (PID) controller although still widely used, may not be sufficient in achieving optimum performance and robustness. In this study, model predictive control (MPC) strategy is developed for a nonlinear dynamic CSTR process, and the performance was compared with the traditional PID controller. The result shows that for a small set point change, MPC has similar performance to the PID controller. MPC performed much better when subjected to a much larger set point change in which the response time is 12 times faster and is able to reduce up to 60% of the loop interaction. The second part of this study is to design a real‐time mobile monitoring system (proof of concept). The overall design allows for real‐time updates on the performance of CSTR remotely. Engineers will be notified when the equipment fails to run at its full performance and generate critical analysis based on the historical data of the equipment. Lastly, a real‐time safety alert allows accidents to be predicted ahead before it happens and allows workers to be notified in real time.
“Easterlies”‐induced precipitation in eastern Patagonia: Seasonal influences of ENSO'S FLAVOURS and SAM
Authors: Agosta Eduardo A. , Hurtado Santiago I. , Martin Paula B. 
Published: February 2020

AbstractThe seasonal influence of the phases of El Niño‐Southern Oscillation (ENSO) and of Southern Annular Mode (SAM) on precipitation over eastern Patagonia is examined. Also, their impact in generating persistent daily easterly moisture flux leading to daily precipitation events. The significant signatures of the drivers on precipitation are found in March–April–May (MAM), June–July–August (JJA) for ENSO and November–December–January (NDJ) for SAM. Over the east coast, precipitation is mainly favoured owing to an overall growth of the seasonal mean number of precipitation days (~30%) by central Niño in JJA and by negative SAM phase in NDJ, and growth of the frequency of persistent events of daily westward moisture flux (~90%) by eastern Niña in MAM. A great spatial variability shapes the anomalies. Evidence is shown for weakened seasonal westerlies linked to Eastern Pacific Niño in MAM. Enhanced daily easterlies with net daily westward moisture flux in the region lead to strong daily precipitation. Growth in precipitation intensity in the northeast coast is also associated with Eastern Pacific Niño in MAM. In the interior lands, south of 45°S, westward moisture flux is increased up to ~200% by negative SAM phase in NDJ. The nature of extratropical low‐frequency transient eddies travelling over the South Pacific will influence the frequency and intensity of daily local precipitation as well as the persistent westward flux during ENSO events.
