Endobiogenika ir funkcijų biologija pagrįsta keturiomis mokslinėmis sąvokomis:1. Žmogaus organizmas yra sudėtinga visuma, susidedanti iš dalių: organų,audinių, ląstelių, branduolių ir genų, kiekviena jų užtikrina tikslų funkcionavimą ir šios organizmo dalys nuolat tarpusavyje sąveikauja.2. Endokrininė sistema valdo medžiagų (angliavandenių, baltymų, riebalų) metabolizmą ir vienu metu gali valdyti save, todėl endokrininė sistema laikoma pagrindine organizmo valdytoja.3. Endokrininė sistema lemia biožymenų (kraujo elementų: raudonųjų ir baltųjų kraujo kūnelių, neutroflų, limfocitų, eozinoflų, monocitų; fermentų, elektrolitų ir kt.) išskyrimą į kraujotaką.4.

MEMPERKUAT EKSISTENSI PENDIDIKAN ISLAM DI ERA 4.0
Authors: Syakhrani Abdul Wahab 
Published: March 2020

Tulisan ini berupaya mendorong perlunya reformasi masif di tubuh pendidikan Islam. Reformasi ini diperlukan agar pendidikan Islam mampu menjawab tantangan dan tuntutan zaman yang terus mengalami perubahan. Selain itu, tulisan ini juga berupaya memberikan tawaran solutif kepada pendidikan Islam dalam menghadapi Era Revolusi Industri 4.0. Sebagaimana dikertahui bersama, bahwa era 4.0 membawa dampak yang luas dalam segala lini kehidupan, tak terkecuali dalam bidang pendidikan. Era yang melahirkan fenomena disruption ini menuntut dunia pendidikan Islam untuk turut menyesuaikan diri. Lulusan pendidikan Islam kini dihadapkan pada tantangan, tuntutan, dan kebutuhan baru yang belum pernah ada sebelumnya. Sehingga perlu dilakukan pembaruan dan inovasi terhadap sistem, tata kelola, kurikulum, kompetensi sumber daya manusia, sarana dan prasarana, budaya, etos kerja, dan lain-lain. Jika tidak demikian, pendidikan Islam akan semakin tertinggal dan usang. Oleh karena itu, perlu dicari langkah-langkah kongkrit bagi pendidikan Islam agar mampu tetap bersaing di era disrupsi ini. Langkah solutifnya adalah dengan turut mendisrupsikan diri.
SNAFU: The Semantic Network and Fluency Utility
Authors: Zemla Jeffrey C. , Cao Kesong , Mueller Kimberly D. , Austerweil Joseph L. 
Published: March 2020

AbstractThe verbal fluency task—listing words from a category or words that begin with a specific letter—is a common experimental paradigm that is used to diagnose memory impairments and to understand how we store and retrieve knowledge. Data from the verbal fluency task are analyzed in many different ways, often requiring manual coding that is time intensive and error-prone. Researchers have also used fluency data from groups or individuals to estimate semantic networks—latent representations of semantic memory that describe the relations between concepts—that further our understanding of how knowledge is encoded. However computational methods used to estimate networks are not standardized and can be difficult to implement, which has hindered widespread adoption. We present SNAFU: the Semantic Network and Fluency Utility, a tool for estimating networks from fluency data and automatizing traditional fluency analyses, including counting cluster switches and cluster sizes, intrusions, perseverations, and word frequencies. In this manuscript, we provide a primer on using the tool, illustrate its application by creating a semantic network for foods, and validate the tool by comparing results to trained human coders using multiple datasets.
Titta: A toolbox for creating PsychToolbox and Psychopy experiments with Tobii eye trackers
Authors: Niehorster Diederick C. , Andersson Richard , Nyström Marcus 
Published: March 2020

AbstractWe present Titta, an open-source toolbox for controlling eye trackers manufactured by Tobii AB from MATLAB and Python. The toolbox provides a wrapper around the Tobii Pro SDK, providing a convenient graphical participant setup, calibration and validation interface implemented using the PsychToolbox and PsychoPy toolboxes. The toolbox furthermore enables MATLAB and Python experiments to communicate with Tobii Pro Lab through the TalkToProLab tool. This enables experiments to be created and run using the freedom of MATLAB and Python, while the recording can be visualized and analyzed in Tobii Pro Lab. All screen-mounted Tobii eye trackers that are supported by the Tobii Pro SDK are also supported by Titta. At the time of writing, these are the Spectrum, Nano, TX300, T60XL, X3-120, X2-60, X2-30, X60, X120, T60 and T120 from Tobii Pro, and the 4C from Tobii Tech.
A Cancellation Nanoflare Model for Solar Chromospheric and Coronal Heating. III. 3D Simulations and Atmospheric Response
Authors: Syntelis P. , Priest E. R. 
Published: March 2020

Abstract
Inspired by recent observations suggesting that photospheric magnetic flux cancellation occurs much more frequently than previously thought, we analytically estimated the energy released from reconnection driven by photospheric flux cancellation, and propose that it can act as a mechanism for chromospheric and coronal heating. Using two-dimensional simulations we validated the analytical estimates and studied the resulting atmospheric response. In the present work, we set up 3D resistive MHD simulations of two canceling polarities in a stratified atmosphere with a horizontal external field to further validate and improve upon the analytical estimates. The computational evaluation of the parameters associated with the energy release are in good qualitative agreement with the analytical estimates. The computational Poynting energy flux into the current sheet is in good qualitative agreement with the analytical estimates, after correcting the analytical expression to better account for the horizontal extent of the current sheet. The atmospheric response to the cancellation is the formation of hot ejections, cool ejections, or a combination of both hot and cool ejections, which can appear with a time difference and/or be spatially offset, depending on the properties of the canceling region and the resulting height of the reconnection. Therefore, during the cancellation, a wide spectrum of ejections can be formed, which can account for the variety of multi-thermal ejections associated with Ellerman bombs, UV bursts, and IRIS bombs, and also other ejections associated with small-scale canceling regions and spicules.

Abstract
Long-period Mira variable stars are considered to have relatively high initial masses and may be potentially useful as tracers of spiral arm structure of the Milky Way. From 2004 to 2017, we monitored long-period Mira candidates selected from the IRAS color–color diagram in the near-infrared K′ band. As an initial result of this study, we found 108 Mira variables and determined their periods, mean magnitudes, and amplitudes. Most of them are located between 0° and 90° in Galactic longitude. The peak of their period distribution is at around 500 days, which is longer than the typical value for Mira variables selected in optical surveys. Distances to our Mira variables have also been estimated using the period–luminosity relation (PLR) in 3.4 μm with the help of a three-dimensional map of interstellar extinction. While the K

s
-band PLR has a large scatter at longer periods (log P > 2.6), the PLR based on the Wide-field Infrared Survey Explorer 3.4 μm data has a much smaller scatter. We compare the spatial distribution of our sample to the spiral arms in the literature, and discuss the possible association of the long-period Mira variables with the spiral arms although the limited spatial coverage and the limited distance accuracy of the current sample prevent us from drawing a firm conclusion.

Reaction time (RT) is important in learning. Relationship of RT to Intelligent Quotient (IQ) and Working Memory (WM) has not been studied in Sri Lankans. To measure the visual RT(VRT), discrimination RT (DRT) and choice RT (CRT) of young adults and to correlate these reaction times (RTs) to IQ and WM. A cross sectional study was conducted among 200 volunteers (18-28 years). RTs were measured using the “reaction timer software” developed locally. WM was assessed using “digit span backward test (DSBT)”. IQ was assessed using Raven’s standard progressive matrices (RSPM). Mean, SD of VRT, CRT and DRT in males were 292.85±32.88ms, 395.75±75.62ms and 407.45±82.11ms respectively. The respective values in females were 317.85±43.15ms, 452.68±96.47ms and 454.26±93.5ms. RTs were faster (p<0.05) in males. VRT was faster (p<0.05) than CRT and DRT in both sexes. CRT and DRT did not differ significantly in both sexes (p>0.05). Mean IQ scores of males and females were 52.17± 6.2 and 51.74±6.2. Respective DSBT scores were 7.55±1.62 and 7.64±1.33. IQ and DSBT scores were not differed (p>0.05) between sexes. RTs had negative correlations with IQ and DSBT score. Only the correlations of IQ with VRT of males (-0.203) and DRT (-0.225) and CRT (-0.235) of females were significant (p<0.05). Significant negative correlation (-0.293) of DSBT score was observed with DRT of females only. RTs were shorter in males. IQ and WM capacity showed negative correlations with RTs. Further studies are necessary to assess the contribution of the processing speed on the IQ and WMC.
LO STATO ATTUALE DEI GHIACCIAI ITALIANI E LA LORO RECENTE EVOLUZIONE

Published: March 2020

Mountain glaciers represent an important hydrological and touristic resource, and their recent evolution provides a dramatic evidence of climate change for the general public. Glacier inventories, quantifying glacier characteristics and evolution, are an important tool to describe and manage high mountain glacier environments and Italy has developed a long tradition in this sector. Our country was the first to provide itself with a glacier inventory, compiled by Comitato Glaciologico Italiano and CNR, showing a glacier surface of 530 km2. A recent project, coordinated by UniversitÃ Statale di Milano with the support of private bodies and the cooperation of Comitato EvK2CNR and Comitato Glaciologico Italiano, led to the development of the new Italian Glacier Inventory, a national atlas produced from the analysis of color orthophotos at high resolution acquired between 2005 and 2011. The New Italian Glacier Inventory lists 903 glaciers, covering an area of 370 km2. The largest part of glacier area is located in Val dâ€™Aosta (36.15% of the total), followed by Lombardia and South Tyrol. 84% of glaciers (considering the number of glaciers) have an area lower than 0.5 km2 and jointly account for 21% of the total glacier surface. Glaciers larger than 1 Km2 make up 9.4% of the total number, but cover 67.8% of the total glacier area. The comparison between data from the New Italian Glacier Inventory and the CGI-CNR inventory (1959-1962) shows a 30% reduction in glacier area in Italy; considering instead the World Glacier Inventory or WGI, published at the end of the â€˜80s, which reported 1381 glaciers and an area of 609 km2, glacier loss sums up to 478 glaciers and an area of 239 km2 (-39%). This shrinkage has led to rapid and significant changes to high mountain landscapes, notably glacier fragmentation, an increase in deglaciated areas, the formation of proglacial lakes and the development of pioneer vegetation.

Published: March 2020

Background:
Discovery of serum myelin oligodendrocyte glycoprotein (MOG) antibody testing in demyelination segregated MOG-IgG disease from AQ-4-IgG positive NMOSD.

Aims:
To study clinico-radiological manifestations, pattern of laboratory and electrophysiological investigations and response to treatment through follow up in MOG-IgG positive patients.

Method:
Retrospective data of MOG-IgG positive patients was collected. Demographics, clinical manifestations at onset and at follow up and relapses, anti AQ-4-IgG status, imaging and all investigations were performed, treatment of relapses and further immunomodulatory therapy were captured.

Results:
In our 30 patients, F: M ratio was 2.75:1 and adult: child ratio 4:1. Relapses at presentation were optic neuritis {ON}(60%), longitudinally extensive transverse myelitis {LETM}(20%), acute disseminated encephalomyelitis {ADEM}(13.4%), simultaneous ON with myelitis (3.3%) and diencephalic Syndrome (3.3%). Salient MRI features were ADEM-like lesions, middle cerebellar peduncle fluffy infiltrates, thalamic and pontine lesions and longitudinally extensive ON {LEON} as well as non-LEON. Totally, 50% patients had a relapsing course. Plasma exchange and intravenous immunoglobulin worked in patients who showed a poor response to intravenous methylprednisolone. Prednisolone, Azathioprine, Mycophenolate and Rituximab were effective attack preventing agents.

Conclusions:
MOG-IgG related manifestations in our cohort were monophasic/recurrent/simultaneous ON, myelitis, recurrent ADEM, brainstem encephalitis and diencephalic Syndrome. MRI features suggestive of MOG-IgG disease were confluent ADEM-like lesions, middle cerebellar peduncle fluffy lesions, LETM, LEON and non-LEON. Where indicated, patients need to go on immunomodulation as it has a relapsing course and can accumulate significant disability. Because of its unique manifestations, it needs to be considered as a distinct entity. To the best of our knowledge, this is the largest series of MOG-IgG disease reported from India.
Les risques de la symbolisation du mal. Essai de confrontation entre La Symbolique du mal et La Littérature et le mal
Authors: Costa Cristina Henrique da 
Published: March 2020

Cet article compare deux livres majeurs : La Symbolique du mal, de Paul Ricœur et La Littérature et le mal, de Georges Bataille. L’articulation de ces deux penseurs que tout semble opposer répond à l’espoir de dégager une forme de compatibilité productive entre eux à travers leur intérêt commun pour le langage du mal. On insistera tout d’abord sur Ricœur : c’est en reconnaissant que le dire de l’expérience du mal passe d’abord nécessairement par un langage symbolique qu’il nous permet de penser l’insistance de Bataille sur la place de la littérature quant au mal. On montrera ensuite que l’affirmation par Bataille d’une lucidité littéraire moderne du mal, tout en permettant de confirmer les thèses de Ricœur au sujet du caractère à la fois historique et langagier de l’expérience du mal, nous conduit aussi à en formuler la principale conséquence : que le langage du mal, marqué du sceau de la créativité poétique, ne peut sans doute pas être tenu pour achevé. On soulignera enfin l’intérêt de cette approche pour interpréter, avec la littérature, les nouvelles expériences du mal aujourd’hui.
Empirically Supported Strategies for Encouraging Critical Thinking
Authors: McCrackin Sarah D. 
Published: March 2020

Critical thinking is the ability to construct and evaluate arguments (Facione, 1990). Teaching students to think critically is undeniably one of the most important goals of university education. Accordingly, much of the teaching literature provides suggestions for improving critical thinking among students. Unfortunately, many of these papers contain anecdotal evidence, relying heavily on personal testimony without the support of empirical data and statistical analysis (Abrami et al., 2008; Behar-Horenstein & Niu, 2011). These findings have important implications for instructors who try to foster critical thinking in their classrooms. The present workshop addresses this problem by discussing the following three teaching techniques which have been empirically tested and found to reliably improve critical thinking across multiple investigations: (a) the use of higher-order questioning (Barnett & Francis, 2012; Fenesi, Sana, & Kim, 2014; Renaud & Murray, 2007; Renaud & Murray, 2008; Smith, 1977; Williams, Oliver, & Stockdale, 2004); (b) peer-to-peer interaction (Abrami et al., 2008; Smith, 1997); and (c) explicit critical thinking instruction (Abrami et al., 2008; Bangert-Drowns, & Bankert, 1990; Behar-Horenstein et al., 2010; Tiruneh et al., 2016).
This workshop is intended for members of all disciplines seeking to work together to develop an empirically supported framework for teaching critical thinking at the university level.
A Criação do imaginário em narrativas de estudantes brasileiros: perspectivas a partir das Olimpíadas de Língua Portuguesa
Authors: Valério Gleiser Mateus Ferreira 
Published: March 2020

Em O fictício e o imaginário, Iser parte da distinção entre realidade e ficcional, abrindo espaço para um terceiro elemento - o imaginário. Para tal, converte-o em experiência do que o autor denomina em um "como se". Por meio de escolhas, o indivíduo seleciona as "chaves" de leitura que utilizará para perceber e receber o texto literário e, deste modo, conceber suas próprias narrativas. Pelo imaginário, o texto se torna algo possível e desenvolve o processo representativo. No presente artigo, a categoria lugar será uma destas “chaves”, partindo das Olimpíadas de Língua Portuguesa (OLP). Durante a realização do concurso, os estudantes participam de um processo pedagógico que se utiliza da Literatura como forma do jovem perceber o “ser” e o “estar no mundo”, partindo de seu lugar (espacial e de fala) no qual se situa para criar narrativas pessoais. Para tal, a OLP tem como tema "O lugar onde vivo", sendo assim, um elemento de seleção é instaurado para o processo criativo que é o espaço vivenciado e experimentado pelo educando. Nesta análise, será utilizado, como base, o poema "As Marias do meu lugar", selecionado e publicizado nas coletâneas de poemas do projeto, ao lado de autores como Carlos Drummond Andrade e Fernando Pessoa, dando um caráter de escrita autoral à produção juvenil. O objetivo não será apenas questionar o processo criativo, mas também trazer o elemento local como potencializador do imaginário ao descrever um espaço fora dos grandes centros ou de capitais – a individualidade de uma pequena cidade do interior do Nordeste brasileiro, seu povo e suas particularidades.
