Hyperbolic topology and bounded locally homeomorphic quasiregular mappings in 3-space
Authors: Apanasov Boris
Published: May 2020

We use our new type of bounded locally homeomorphic quasiregular mappings in the unit 3-ball to address long standing problems for such mappings, including the Vuorinen injectivity problem. The construction of such mappings comes from our construction of non-trivial compact 4-dimensional cobordisms $M$ with symmetric boundary components and whose interiors have complete 4-dimensional real hyperbolic structures. Such bounded locally homeomorphic quasiregular mappings are defined in the unit 3-ball $B^3\subset \mathbb{R}^3$ as mappings equivariant with the standard conformal action of uniform hyperbolic lattices $\Gamma\subset \operatorname{Isom} H^3$ in the unit 3-ball and with its discrete representation $G=\rho(\Gamma)\subset \operatorname{Isom} H^4 $. Here, $G$ is the fundamental group of our non-trivial hyperbolic 4-cobordism $M=(H^4\cup\Omega(G))/G,$ and the kernel of the homomorphism $\rho\!:\! Gamma\rightarrow G$ is a free group $F_3$ on three generators.

,,Apparent Life“: Botanik, Visualität und Literatur bei Erasmus Darwin1
Authors: Kaulbarsch Vera
Published: May 2020

,,GENTLE READER! — Lo, here a CAMERA OBSCURA is presented to thy view, in which are lights and shades dancing on a whited canvas, and magnified into apparent life!“220 Mit dieser Ansprache beginnt das lange Prosagedicht The Loves of the Plants, der zweite
Teil des insgesamt zwei Bände umfassenden Gedichtes The Botanic Garden (1791), in dem der Naturphilosoph, Arzt und Dichter Erasmus Darwin versucht, die damals neuen botanischen Erkenntnisse Carl von Linnés literarisch darzustellen. Eine solche Zusammenführung von bahnbrechender
naturwissenschaftlicher Forschung und literarischer Sprache entpuppt sich auf mehreren Ebenen als ein gewagtes Experiment. Im Zentrum von Darwins Text steht das in Systema Naturae (1735) formulierte Klassifizierungssystem Linnés, der die Aufteilung in männliche und weibliche
Pflanzenteile zur Grundlage seiner Taxonomie machte. Im 18. Jahrhundert rückte somit die Sexualität von Pflanzen – und insbesondere der Blüten, da u.a. Anzahl und Anordnung von Stempel und Staubblättern die sexuelle Kategorisierung bestimmte221 –
auf eine Weise in den Mittelpunkt, die Linné und anderen Vertretern der These der Pflanzensexualität wiederholt den Vorwurf der Obszönität einbrachte.222 Darwins Projekt einer Literarisierung der neuen Botanik kreuzt sich dabei mit Linnés Anliegen, die
Sexualität der Pflanzen immer wieder in Analogie zur menschlichen Sexualität zu setzen: ,,Linnaeus consistently went beyond biological analogies in order to import social analogies into his descriptions of plant life.“223 Während Linné somit
auf revolutionäre Weise die Botanik in einen Diskurs transformiert, in dem Sexualität und Geschlechterrollen verhandelbar werden, kleidet Darwin wiederum diese radikalen Ideen in eine dichterische Sprache, die überaus konventionell ist. Darwins Lehrgedichte stehen am Ende einer
Lyriktradition, als deren herausragender Vertreter Alexander Pope gilt.224 Bereits wenige Jahre nach Erscheinen seiner Gedichte wirkt sein Stil für die nachfolgende Generation überlebt und altmodisch – Coleridge findet sich ,,nauseate[d]“225 angesichts
Darwins Lyrik, während Byron ,,flimsy DARWIN“ als ,,the mighty master of unmeaning rhyme“226 abkanzelt. Auch wenn eine gewisse Ermüdung bei der Lektüre der sturen Gleichmäßigkeit des Reimschemas durchaus verständlich ist, möchte die
folgende Auseinandersetzung mit The Loves of the Plants nicht nur die Radikalität der von Darwin rezipierten Ideen berücksichtigen, sondern auch herausarbeiten, welche Komplexität das Gedicht als ein literarischer Text bietet. Hierzu gehört auch die Form dieses Poem
with Philosophical Notes, das eine Zweiteilung in die lyrische Darstellung und einen Fußnotenapparat mit wissenschaftlichen Anmerkungen vornimmt.

Published: May 2020

Introducción: el estado de alarma por la actual pandemia por coronavirus 2019 (COVID-19) ha obligado a adoptar medidas especiales tanto en cirugía electiva como en cirugía urgente no demorable con el objeto de minimizar el riesgo de contagio. Sin embargo, dichas medidas difieren en numerosos aspectos entre centros hospitalarios y sociedades científicas. Además, la falta de experiencia y formación sobre el modo de actuar en estas situaciones aumentan la incertidumbre y el riesgo de contagio accidental.

Objetivo: presentamos nuestra experiencia tras la realización de la primera cirugía urgente abdominal realizada en nuestro centro sobre un paciente positivo para COVID-19.

Caso clínico: varón de 21 años con dolor en fosa iliaca derecha (FID) y síndrome emético de dos días compatible con apendicitis aguda. Comentaba anosmia desde hacía 2 semanas tras volver de un viaje a Londres. Se le practicó la prueba de detección de ARN del SARS-CoV-2 en cepillado nasofaringeo que resultó positiva. Se actívó el protocolo hospitalario para paciente quirúrgicos COVID-19 positivo y se realizó una apendicectomía abierta por apendicitis gangrenosa perforada.

Discusión: se trata de la primera experiencia quirúrgica urgente con una paciente positivo para COVID-19 realizada en el Hospital Virgen de Valme. Tras la activación del protocolo quirúrgico detectamos diversos problemas relacionados con la formación en este tipo de situaciones y con los equipos de protección individual. Creemos imprescindible que cada centro debe ofrecer formación teórica y práctica mediante simulación de las situaciones urgentes y en el manejo de los equipo de protección así como optimizar los equipos de protección individual para mejorar el confort y la visión del cirujano.

Mesenteric solitary fibrous tumor: keys to diagnosis.
Authors: Garrido Márquez I , Dávila Arias C , Moya Sánchez E
Published: May 2020

El tumor fibroso solitario es una rara neoplasia de origen mesenquimal que normalmente aparece en la pleura, pero no de forma exclusiva. Es importante conocer que podemos encontrarlo en localizaciones extrapleurales, como es el caso del mesentérico.

El diagnóstico preoperatorio es difícil debido a las manifestaciones clínicas inespecíficas, por lo que en muchas ocasiones se realiza mediante el análisis histológico tras las extirpación quirúrgica.

Existen hallazgos radiológicos que pueden orientar hacia su diagnóstico y posible malignización, por lo que son de gran importancia para realizar un correcto abordaje y manejo preoperatorio.

Published: May 2020

In recent years, the number of researches in the field of artificial limbs has increased significantly in order to improve the performance of the use of these limbs by amputees. During this period, High-Density surface Electromyography (HD-sEMG) signals have been employed for hand gesture identification, in which the performance of the classification process can be improved by using robust spatial features extracted from HD-sEMG signals. In this paper, several algorithms of spatial feature extraction have been proposed to increase the accuracy of the SVM classifier, while the histogram oriented gradient (HOG) has been used to achieve this mission. So, several feature sets have been extracted from HD-sEMG signals such as; features extracted based on HOG denoted by (H); features have been generated by combine intensity feature with H features denoted as (HI); features have been generated by combine average intensity with H features denoted as (AIH). The proposed system has been simulated by MATLAB to calculate the accuracy of the classification process, in addition, the proposed system is practically validated in order to show the ability to use this system by amputees. The results show the high accuracy of the classifier in real-time which leads to an increase in the possibility of using this system as an artificial hand.

TÜRKİYE’DE KATILIM BANKALARI VE MEVDUAT BANKALARININ FAİZ VE KAR ORANLARI İLE TAKİPTEKİ KREDİ ORANLARI ARASINDAKİ İLİŞKİSİNİN BELİRLENMESİ
Authors: KOLUKISA Harun
Published: May 2020

Katılım bankaları mevduat bankalarına göre
göreceli olarak daha yüksek kar/faiz oranlarından kredi kullandırmaktadır. Daha
yüksek maliyetle kredi kullandıran katılım bankalarını mevduat bankalarına
tercih eden müşterilerin daha düşük ödeme gücüne sahip sorunlu müşteri kitlesi
olacağı ve bunun sonucu olarak da katılım bankalarının takipteki kredi
oranlarının mevduat bankalarının takipteki kredi oranlarına göre daha yüksek
olacağı öngörülmektedir. Bu çalışmada Ocak 2005 ve Eylül 2015 tarihleri arasında Türkiye’de faaliyet
gösteren Katılım Bankalarının kredi kullandırımlarında uygulanan aylık kar
oranları ve takipteki kredi oranları (NPL-non performing loan), Türkiye’de
faaliyet gösteren Mevduat Bankaların kredi kullandırımlarında uygulanan aylık
faiz oranları ve takipteki kredi oranları verileri kullanılmıştır. Katılım
bankaları ve mevduat bankalarının kar ve faiz oranları ile takipteki kredi
oranları arasındaki ilişki; korelasyon, VAR, Granger nedensellik ve etki-tepki
analizleriyle incelenmiştir. Analizler neticesinde takipteki kredi oranlarının
direkt olarak kar/faiz oranlarının bir sonucu olmadığı yönünde bulgular elde
edilmiştir. Analiz sonuçlarına göre, öngörüldüğü gibi katılım bankalarının
mevduat bankalarından daha yüksek kar/faiz oranından kredi kullandırması
takipteki kredi oranlarını doğrudan etkilemediği belirlenmiştir.

Periodic Narrowband Radio Wave Emissions and Inward Plasma Transport at Saturn's Magnetosphere
Authors: Wing S. , Brandt P. C. , Mitchell D. G. , Johnson J. R. , Kurth W. S. , Menietti J. D.
Published: May 2020

The abrupt brightening of an Energetic Neutral Atom (ENA) blob or cloud has been interpreted as plasma injection in the Kronian magnetosphere (termed ENA injection herein). Morphologically, there appears to be two types of abrupt ENA cloud brightening: (1) the brightening of a large cloud usually seen at distances >10–12 R
s (R
s ∼ 60,268 km) in the midnight or postmidnight region; (2) the brightening of a smaller cloud usually seen at distances <10–12 R
s around 21–03 magnetic local time. Among many radio waves observed at Saturn, type 2 ENA injections correlate best with the 5 kHz narrowband (NB) waves. Using Cassini Ion and Neutral Camera (INCA) and Radio and Plasma Wave Science (RPWS) data, we examine the periodicities of the type 2 ENA injections and the 5 kHz NB emissions as well as their cross-correlations, which have been previously used to measure the lag times or phase differences. Because correlational analysis can only establish linear relationships, we also use mutual information to establish linear and nonlinear relationships. On average, the peak of the 5 kHz NB emission lags those of the type 2 ENA injection by about a few minutes to 2 hr. The injection of hot plasma to the inner magnetosphere can lead to temperature anisotropy, which can generate electrostatic upper hybrid waves, which upon encountering the high-density gradient at the outer edge of the Enceladus density torus, can mode convert to Z mode and then to O mode. The 5 kHz NB waves commonly propagate in the O mode.
A Tidal Disruption Event Candidate Discovered in the Active Galactic Nucleus SDSS J022700.77-042020.6

Published: May 2020

We report the discovery of a tidal disruption event (TDE) candidate occurring in the active galactic nucleus (AGN) SDSS J022700.77-042020.6. A sudden increase in flux from J0227-0420 during the second half of 2009 appears in the long-term optical, UV, and near-IR (NIR) light curves. A plateau phase, following an initial decline, is seen in the near-UV (NUV) and optical light curves. We find possible evidence that the plateau in the NUV band may lag behind the optical ones by ∼70–80 days with also a much shorter duration, that is, ∼7–15 days against ∼40–50 days. The long-term NUV/optical (after the plateau phase), NIR, and mid-infrared (MIR) light curves can be well characterized with a form of L(t) ∝ t
−β
, consistent with the expectation of a TDE. The plateaus can be explained if stellar streams collide with the preexisting disk at different radii. Though the overall fallback rate decreases, the material in the outer disk drifts inward and increases the local accretion rate in the inner region, producing the NUV/optical plateaus. The possible lag is then attributed to viscosity delay. The index β of the NIR J, H, and K

bands (∼1.4–3.3) is steeper than that of the UV/optical (∼0.7–1.3) and MIR bands (∼0.9–1.8), which may suggest that a certain fraction of the dust in the inner region of the torus may be sublimated during the TDE phase. Our results indicate that, due to collisions between stellar debris and the preexisting disk, the light curves of TDEs occurring in AGNs may show distinctive features, which may shed new light on the accretion process.

Petits corps malades. De la valeur des tares dans l’adoption internationale
Authors: Roux Sébastien
Published: May 2020

Depuis 2005 le nombre d’enfants adoptés à l’international a chuté d’environ 80 %. Cette contraction des flux s’est accompagnée d’une transformation du profil des enfants accueillis, et la majorité des adoptés appartiennent aujourd’hui à la catégorie dite « des enfants à particularités » ou des « enfants à besoins spécifiques ». Si ces expressions recouvrent en réalité une grande diversité de situations, la plupart des enfants n’en souffre pas moins d’une pathologie ou d’un trouble, curable ou non, qui transforme singulièrement les modalités par lesquelles ces familles se constituent. À partir d’une enquête ethnographique conduite en France et au Vietnam, cet article interroge l’irruption de la médecine dans l’accompagnement à la parentalité adoptive et le poids des diagnostics dans la réalisation des projets de vie. En analysant les pratiques et les discours des acteurs impliqués, cette contribution révèle le processus ambigu qui accorde progressivement aux enfants moins désirés une valeur insoupçonnée, et interroge les modalités par lesquelles se façonnent et se transforment les vies familiales.

Au début de l’année, la Roumanie a connu des mouvements de protestation. Ceux-ci s’opposent à une dérive « illibérale » 1 , caractéristique de plusieurs pays d’Europe centrale. Ils s’inscrivent dans une histoire et une situation sociale particulières. De quel avenir sont-ils porteurs ?
Réflexions sur la prévention des risques naturels en Nouvelle-Calédonie : un regard géohistorique
Authors: Le Duff Matthieu , Dumas Pascal , Allenbach Michel
Published: May 2020

La Nouvelle-Calédonie connaît un cadre institutionnel particulier interdisant une mise en application simple de la règlementation métropolitaine en matière de prévention des risques naturels. À ce jour, les institutions locales n’ont pas apporté de réponses globales à cette question qui pose pourtant de nombreux enjeux. Certains dispositifs existent néanmoins et dans cet article nous proposons d’apporter un éclairage historique sur ceux-ci, afin de mieux saisir les lignes de forces et de faiblesses des stratégies déployées sur ce territoire au fil de l’histoire. Notre objectif est de contribuer à la réflexion sur ce sujet essentiel de la stratégie à construire en matière de prévention des risques naturels en Nouvelle-Calédonie.
Le nihilisme comme destin de la philosophie moderne. Le diagnostic de Jacobi et de Fichte
Authors: Radrizzani Ives
Published: May 2020

L’accusation de nihilisme portée par Jacobi contre Fichte en marge de la Querelle de l’athéisme avait à l’origine une tout autre cible, les Lumières, accusées d’accorder un rôle démesuré à la raison humaine conduisant à la suppression de toute transcendance. Paradoxalement, celui dont Jacobi fait son adversaire privilégié est très largement d’accord avec le diagnostic sévère porté sur les Lumières, qu’il estime à son tour responsables de la dérive nihiliste. Les remèdes préconisés par les deux penseurs pour remédier au mal de l’époque sont toutefois diamétralement opposés. Tandis que l’un se fait l’avocat d’un rationalisme prémoderne en prônant moins de raison, l’autre estime au contraire nécessaire d’instaurer plus de raison.
Estimating the time interval between transmission generations when negative values occur in the serial interval data: using COVID-19 as an example

The coronavirus disease 2019 (COVID-19) emerged in Wuhan, China in the end of 2019, and soon became a serious public health threat globally. Due to the unobservability, the time interval between transmission generations (TG), though important for understanding the disease transmission patterns, of COVID-19 cannot be directly summarized from surveillance data. In this study, we develop a likelihood framework to estimate the TG and the pre-symptomatic transmission period from the serial interval observations from the individual transmission events. As the results, we estimate the mean of TG at 4.0 days (95%CI: 3.3-4.6), and the mean of pre-symptomatic transmission period at 2.2 days (95%CI: 1.3-4.7). We approximate the mean latent period of 3.3 days, and 32.2% (95%CI: 10.3-73.7) of the secondary infections may be due to pre-symptomatic transmission. The timely and effectively isolation of symptomatic COVID-19 cases is crucial for mitigating the epidemics.

Authors: Sun Guangxun ,   School of Mathematics and Statistics, Central South University, Changsha 410083, China, Dai Binxiang
Published: May 2020

Based on ecological significance, a delayed diffusive predator-prey system with food-limited and nonlinear harvesting subject to the Neumann boundary conditions is investigated in this paper. Firstly, the sufficient conditions of the stability of nonnegative constant steady state solutions of system are derived. The existence of Hopf bifurcation is obtained by analyzing the associated characteristic equation and the conditions of Turing instability are derived when the system has no delay. Furthermore, the occurrence conditions the Hopf bifurcation are discussed by regarding delay expressing the gestation time of the predator as the bifurcation parameter. Secondly, by using upper-lower solution method, the global asymptotical stability of a unique positive constant steady state solution of system is investigated. Moreover, we also give the detailed formulas to determine the direction, stability of Hopf bifurcation by applying the normal form theory and center manifold reduction. Finally, numerical simulations are carried out to demonstrate our theoretical results.
A Bibliometric Analysis of the Papers Published in the Journal of Artificial Intelligence in Education from 2015-2019
Authors: Baek Clare , Doleck Tenzin
Published: May 2020

To analyze the current research status and trends of the artificial intelligence in education field, we applied bibliometric methods to examine the articles published in one of the representative journals of the field, International Journal of Artificial Intelligence in Education, from 2015 to 2019. We analyzed 135 articles retrieved from the Web of Science database and examined prolific countries, collaboration networks, prolific authors, keywords, and the citations the articles received. Through examining keywords, we found that the authors largely focused on students and learning. Through examining prolific authors and countries, we found active publication of corresponding authors from United States, United Kingdom, Canada, and Germany. We found international collaboration among some researchers and institutions, such as strong collaboration network between United States and Canada. We suggest reinforcement in building more widespread international partnership and expanding collaboration network by including diverse institutions. International collaboration and expanded institutional network can improve research by incorporating various perspectives and expertise.
A Numerical Analysis of the Dynamic Stall Mechanisms on a Helicopter Rotor from Light to Deep Stall
Authors: Castells Camille , Richez François , Costes Michel
Published: May 2020

A loose coupling methodology between computational fluid dynamics and Comprehensive Analysis codes (elsA/HOST) is used to simulate a helicopter rotor in dynamic stall condition. Three stalled forward flight conditions have been selected in the wind tunnel 7A rotor test data to
investigate the evolution of the stall mechanisms from a light stall to a deep stall condition. A decrease in the RPM is used to increase the rotor load. The lower the RPM the more severe the stall is. A double stall is observed in the lowest RPM case. The simulations are in satisfactory agreement
with the experiment and are used to identify the mechanisms leading to the different stall events, notably the blade–vortex interaction. Rotormaps of the flow-separation regions are computed from numerical results, and similar regions of separated flow are observed in all the cases.
These flow-separations originate from different aeroelastic mechanisms depending on their position on the rotor disk. As the rotor thrust coefficient is increased, some of these flow separations grow and lead to stall events.
Regional Development Agencies in Turkey on the Scope of Governance and Local Elites: An Evaluation after 10-years-experience
Authors: Sadioğlu Uğur , Dede Kadir , Göçoğlu Volkan
Published: May 2020

Under the influence of globalization and the European Union membership accession process, important administrative reform initiatives have been taken in Turkey in the 2000s in the framework of economic, social, political, cultural and technological needs. In this process, central government agencies and administrations, public financial management, local governments and similar public organizations have undergone important transitions. The most important initiative taken to achieve regional governance is the establishment of Regional Development Agencies (RDAs). The present study performs a 10-year longitudinal analysis of RDAs in Turkey in the context of governance and local elites. The first phase of the study was conducted in 2010, and the second phase was conducted in 2019. The aim of the study is to evaluate whether RDAs have realized their potential in local democracy, sustainable development and decentralization, as well as to define the characteristics of policies to be pursued in line with further development of these agencies. Consequently, it has been observed that maintaining a centralized state tradition, along with institutional deficiencies, has transformed RDAs into an apparatus of the central government.
Happiness, Love, Sustainable Development, and the Law: The Concept of a New Social Model and the Role of State and Law
Authors: Pličanič Senko
Published: May 2020

In the article, the author discusses the main reasons for the failure to achieve sustainable development. He believes that the main reason for that failure is the excessive and one-sided orientation of Western civilization toward the material dimension of our lives. Behind that lies an even deeper mechanism that controls our actions: the human desire “to be happy”. The author believes that we are not aware that the path to happiness is associated with both spiritual and material growth, not material growth alone. Our obsession with materials is rooted in the belief that material (economic) growth is the way to happiness. We have interfered in the environment and in other people’s lives so recklessly primarily due to our material insatiability. However, love is essential in our lives, and the path to love goes through spiritual and material growth. Therefore, the author stresses the necessity of transforming the existing development paradigm into a new one with a comprehensive view of development, which will include spiritual and material growth. We should “use” the state and the law as primary tools in achieving happiness as our main goal. To achieve sustainable development, we need a “sustainable state” and “sustainable law”.
