Grand challenges for global brain sciences
Authors:   Global Brain Workshop 2016 Attendees
Published: December 2016

The next grand challenges for science and society are in the brain sciences. A collection of 60+ scientists from around the world, together with 15+ observers from national, private, and foundations, spent two days together discussing the top challenges that we could solve as a global community in the next decade. We settled on three challenges, spanning anatomy, physiology, and medicine. Addressing all three challenges requires novel computational infrastructure. The group proposed the advent of The International Brain Station (TIBS), to address these challenges, and launch brain sciences to the next level of understanding.

Statistical analysis of surface roughness of machined graphite by means of CNC milling
Authors: Sánchez López Orquídea , Rosas González Armando , Hernández Castillo Ignacio 
Published: December 2016

The aim of this research is to analyze the influence of cutting speed, feed rate and cutting depth on the surface finish of grade GSP-70 graphite specimens for use in electrical discharge machining (EDM) for material removal by means of Computer Numerical Control (CNC) milling with low-speed machining (LSM). A two-level factorial design for each of the three established factors was used for the statistical analysis. The analysis of variance (ANOVA) indicates that cutting speed and feed rate are the two most significant factors with regard to the roughness obtained with grade GSP-70 graphite by means of CNC milling. A second order regression analysis was also conducted to estimate the roughness average (Ra) in terms of the cutting speed, feed rate and cutting depth. Finally, the comparison between predicted roughness by means of a second order regression model and the roughness obtained by machined specimens considering the combinations of low and high levels of roughness is also presented.
Fast calculation of the maximum power point of photovoltaic generators under partial shading

Published: December 2016

This paper presents a method to calculate the energy production of photovoltaic generators considering partial shading or mismatched conditions. The proposed method is based on the complete one-diode model including the bypass diode in its exponential form, where the current and voltage values of the modules composing the photovoltaic panel array are calculated without using the Lambert-W function. In addition, the method introduces a procedure to calculate the vicinity of the maximum power points, which enables the reduction of the operations required to obtain the global maximum. The proposed method provides short simulation times and high accuracy. On the other hand, since the method does not require complex mathematical functions, it can be implemented straightforwardly on known software packages and development languages such as C and C++. Those characteristics make this method a useful tool to evaluate the economic viability and return-of-investment time of photovoltaic installations. Simulation results and comparisons with a classical procedure confirm the good performance of the proposed method in terms of execution time and accuracy.

Published: December 2016

This paper presents results stemming from a comparative experimental analysis of two warm-mix asphalts (WMA) and a dense-graded hot-mix asphalt (HMA). In order to evaluate asphalt mixture behavior, physical and rheological tests were conducted, including tests on resilient modulus, resistance to moisture-induced damage, resistance to fatigue and resistance to permanent deformation. Samples studied were subjected to short (STOA) and long-term (LTOA) aging. As far as asphalt mixture composition is concerned, the same particle size distribution and coarse aggregate were employed for both mixture types. The control HMA mixture was produced with AC 60-70, and the WMAs used the same asphalt cement modified with two chemical additives (Rediset WMX® and Cecabase RT®). The modified mixtures exhibited better resistance to permanent deformation, aging and moisture-induced damage (versus the control mixture). Likewise, WMAs generally saw increased fatigue resistance under controlled-stress loading, which rheological characterization showed is mainly attributable to binder additives and their concomitant modifications.

Published: December 2016

Oriental Chaco, part of the Great American Chaco, embraces a plain area with soft slopes towards the west-east region. In this region, different kinds of landscapes and vegetation converge, both conditioned by topographical and pluviometric gradients. This region undergoes processes of fragmentation and habitat loss due to intense human activities such as deforestation, agricultural exploitation, construction of a dam, and pollution. In order to contribute to the knowledge of the Oriental Chaco biodiversity, we studied the herpetofauna during one year. We sampled four sites between the coordinates 25° 00' S, 58° 00' W and 27º 00' S, 61º 00' W in the provinces of Chaco and Formosa. Eighty-eight species were registered in the studied places. The higher biodiversity was in grid 46.

Authors: Barbosa Orivaldo Alves , De Souza Anna Dorotheia Bezerra , Vasconcelos Cristiane Souza , Lemos Paola Lima 
Published: December 2016

Transverse myelitis (TM) is a clinical syndrome in which an inflammatory process injures the spinal cord potentially resulting in weakness, sensory abnormalities and autonomic dysfunction. The main causes are post-infectious, post-vaccination, autoimmune and demyelinating diseases. In a literature review based on five cases of TM during pregnancy and puerperal period have been reported. We report a female patient in the immediate postpartum period who presented acute transverse myelites after receiving double viral vaccine (measles and rubella). After exclusion of other causes, patient received methylprednisolone in high doses ( 1000 mg for 3 consecutives days) and had complete clinical reversal. Thus it is intended to report this rare occurrence which is post-vaccination TM in the postpartum period.

Microgenetic Learning Analytics Methods: Hands-on Sequence Analysis Workshop Report
Authors: Aghababyan Ani , Martin Taylor , Janisiewicz Phillip , Close Kevin 
Published: December 2016

Learning analytics is an emerging discipline and, as such, it benefits from new tools and methodological approaches. This work reviews and summarizes our workshop on microgenetic data analysis techniques using R, held at the 2nd annual Learning Analytics Summer Institute in Cambridge, Massachusetts on June 30th, 2014. Specifically, this paper introduces educational researchers to our experience using data analysis techniques with the RStudio development environment to analyze temporal records of 52 elementary students’ affective and behavioral responses to a digital learning environment. In the RStudio development environment, we used methods such as hierarchical clustering and sequential pattern mining. We also used RStudio to create effective data visualizations of our complex data. The scope of the workshop, and this paper, assumes little prior knowledge of the R programming language, and thus covers everything from data import and cleanup to advanced microgenetic analysis techniques. Additionally, readers will be introduced to software setup, R data types, and visualizations. This paper not only adds to the toolbox for learning analytics researchers (particularly when analyzing time series data), but also shares our experience interpreting a unique and complex dataset.

Gas, Grass or Ass, No One Rides for Free: The Mohawk Mayor
Authors: Casson Rebecca 
Published: December 2016

In November 2013 Darryn Lyons, a former celebrity photographer well-known for his colourful antics, was directly elected as mayor of Geelong, the second largest city in the State of Victoria, Australia. Also known as “Mr Paparazzi” and “The Mohawk Mayor”, Lyons’s leadership lasted just 30 months before the Victorian State Government sacked him and dissolved the entire Geelong Council, revealing a pre-existing culture of bullying that appeared to be compounded by Lyons’s celebrity persona. How did Lyons’s persona affect Geelong’s newly established procedures for a directly elected mayor? Drawing on one particularly controversial incident, and using data collected from Lyons’s autobiography, together with media articles, official documents and social media, this article discusses how - as a celebrity politician - Lyons appeared to be unable to effectively separate his celebrity persona from his public persona. This seemed to drown out Geelong’s important issues, and undermined the legitimacy of local government. The current literature on directly elected mayors does not include consideration of how electing a celebrity as mayor complicates the problems of legitimacy in local government, and there is a paucity of literature on directly elected celebrity mayors in Australia. An emerging literature on directly elected mayors primarily addresses problems with legitimacy in contemporary politics, while the literature on celebrity politics changing legitimacy has been well established. Using the Lyons case, this article examines both literatures and contributes to the national and international debate on directly elected celebrity mayors.

The ‘Numerus Clausus’ Principle for Securitiesin the Polish Legal SystemSummaryMost specialists on the doctrine of Polish private law hold that thereis a numerus clausus principle for securities in Polish law, although it hasnot been specifically put into words in any act of legislation. According tothe principle only those types of securities may be issued which are regulated by a statute. This means a prohibition on the issue of securities thathave not been legally recognised. There are only a few opinions that saythere is no numerus clausus on securities in Polish legal doctrine. Thisquestion has been the subject of a heated debate, which has attenuatedover the last years. However, many issues have neither been scrutinised nor even noticed. There are still several points worthy of consideration.The author’s aim in this paper is to review the arguments for and againstnumerus clausus; some of them have never been examined before. Hisanalysis leads him to conclude that there is a numerus apertus (i.e. norestrictions) on some securities, such as bonds, while others such asshares, which endow their holder with special rights, are subject to legalrestrictions. The article is an offshoot of research for a dissertation onprivate law conducted on an individual research programme supervisedby Dr. M. Spyra at Collegium Invisibile in the 2013/2014 academic year.
ON THE RADIAL VELOCITY DETECTION OF ADDITIONAL PLANETS IN TRANSITING, SLOWLY ROTATING M-DWARF SYSTEMS: THE CASE OF GJ 1132

Published: December 2016

ABSTRACT
M-dwarfs are known to commonly host high-multiplicity planetary systems. Therefore, M-dwarf planetary systems with a known transiting planet are expected to contain additional small planets (r

p
≤ 4 R
⊕, m

p
≲ 20 M
⊕) that are not seen in transit. In this study, we investigate the effort required to detect such planets using precision velocimetry around the sizable subset of M-dwarfs that are slowly rotating (P
rot ≳ 40 days), and hence more likely to be inactive. We focus on the test case of GJ 1132. Specifically, we perform a suite of Monte-Carlo simulations of the star’s radial velocity signal, featuring astrophysical contributions from stellar jitter due to rotationally modulated active regions, as well as Keplerian signals from the known transiting planet and hypothetical additional planets not seen in transit. We then compute the detection completeness of non-transiting planets around GJ 1132 and consequently estimate the number of RV measurements required to detect those planets. We show that, with 1 m s−1 precision per measurement, only ∼50 measurements are required to achieve a 50% detection completeness for all non-transiting planets in the system, as well as planets that are potentially habitable. Throughout this work, we advocate the use of Gaussian process regression as an effective tool for mitigating the effects of stellar jitter including stars with high activity. Given that GJ 1132 is representative of a large population of slowly rotating M-dwarfs, we conclude with a discussion of how our results may be extended to other systems with known transiting planets, such as those that will be discovered with TESS.
RADIATIVE TRANSFER MODEL OF DUST ATTENUATION CURVES IN CLUMPY, GALACTIC ENVIRONMENTS
Authors: Seon Kwang-Il , Draine Bruce T. 
Published: December 2016

ABSTRACT
The attenuation of starlight by dust in galactic environments is investigated through models of radiative transfer in a spherical, clumpy interstellar medium (ISM). We show that the attenuation curves are primarily determined by the wavelength dependence of absorption rather than by the underlying extinction (absorption+scattering) curve; the observationally derived attenuation curves cannot constrain a unique extinction curve unless the absorption or scattering efficiency is specified. Attenuation curves consistent with the “Calzetti curve” are found by assuming the silicate-carbonaceous dust model for the Milky Way (MW), but with the 2175 Å bump suppressed or absent. The discrepancy between our results and previous work that claimed the Small Magellanic Cloud dust to be the origin of the Calzetti curve is ascribed to the difference in adopted albedos; we use the theoretically calculated albedos, whereas the previous works adopted albedos derived empirically from observations of reflection nebulae. It is found that the attenuation curves calculated with the MW dust model are well represented by a modified Calzetti curve with a varying slope and UV bump strength. The strong correlation between the slope and UV bump strength, as found in star-forming galaxies at

, is well reproduced when the abundance of the UV bump carriers is assumed to be 30%–40% of that of the MW dust; radiative transfer effects lead to shallower attenuation curves with weaker UV bumps as the ISM is more clumpy and dustier. We also argue that some local starburst galaxies have a UV bump in their attenuation curves, albeit very weak.
THE FRAGMENTATION AND STABILITY OF HIERARCHICAL STRUCTURE IN SERPENS SOUTH
Authors: Friesen R. K. , Bourke T. L. , Francesco J. Di , Gutermuth R. , Myers P. C. 
Published: December 2016

ABSTRACT
Filamentary structures are ubiquitous in molecular clouds, and have been recently argued to play an important role in regulating the size and mass of embedded clumps through fragmentation and mass accretion. Here, we reveal the dynamical state and fragmentation of filamentary molecular gas associated with the Serpens South protocluster through analysis of wide (

) observations of NH3 (1, 1) and (2, 2) inversion transitions with the Green Bank Telescope. Detailed modeling of the NH3 lines reveals that the kinematics of the cluster and surrounding filaments are complex. We identify hierarchical structure using a dendrogram analysis of the NH3 emission. The distance between neighbor structures that are embedded within the same parent structure is generally greater than expected from a spherical Jeans analysis, and is in better agreement with cylindrical fragmentation models. The NH3 line width-size relation is flat, and average gas motions are sub- or trans-sonic over all physical scales observed. Subsonic regions extend far beyond the typical 0.1 pc scale previously identified in star-forming cores. As a result, we find a strong trend of decreasing virial parameter with increasing structure mass in Serpens South. Extremely low virial parameters on the largest scales probed by our data suggest that the previously observed, ordered magnetic field is insufficient to support the region against collapse, in agreement with large radial infall motions previously measured toward some of the filaments. A more complex magnetic field configuration in the dense gas, however, may be able to support the filaments.
VERY LONG-PERIOD PULSATIONS BEFORE THE ONSET OF SOLAR FLARES

Published: December 2016

ABSTRACT
Solar flares are the most powerful explosions occurring in the solar system, which may lead to disastrous space weather events and impact various aspects of our Earth. It remains a big challenge in modern astrophysics to understand the origin of solar flares and predict their onset. Based on the analysis of soft X-ray emission observed by the Geostationary Operational Environmental Satellite, this work reports a new discovery of very long-periodic pulsations occurring in the preflare phase before the onset of solar flares (preflare-VLPs). These pulsations typically have periods of 8–30 min and last for about 1–2 hr. They are possibly generated from LRC oscillations of plasma loops where electric current dominates the physical process during magnetic energy accumulation in the source region. Preflare-VLPs provide essential information for understanding the triggering mechanism and origin of solar flares, and may be a convenient precursory indicator to help us respond to solar explosions and the corresponding disastrous space weather events.
