Published: January 2021

Abstract
As COVID-19 cases continue to rise globally, many researchers have developed mathematical models to help capture the dynamics of the spread of COVID-19. Specifically, the compartmental SEIR model and its variations have been widely employed. These models differ in the type of compartments included, nature of the transmission rates, seasonality, and several other factors. Yet, while the spread of COVID-19 is largely attributed to a wide range of social behaviors in the population, several of these SEIR models do not account for such behaviors. In this project, we consider novel SEIR-based models that incorporate various behaviors. We created a baseline model and explored incorporating both explicit and implicit behavioral changes. Furthermore, using the Next Generation Matrix method, we derive a basic reproduction number, which indicates the estimated number of secondary cases by a single infected individual. Numerical simulations for the various models we made were performed and user-friendly graphical user interfaces were created. In the future, we plan to expand our project to account for the use of face masks, age-based behaviors and transmission rates, and mixing patterns.

A TANULMÁNY CÉLJA
Tanulmányunkban a borturizmusban résztvevők utazási szokásait, borrégiókkal és pincészetekkel kapcsolatos elvárásait és preferenciáit vizsgáltuk.
ALKALMAZOTT MÓDSZERTAN
A releváns szakirodalmi vonatkozások összefoglalását követően a Nagy Bor Teszt 2018-as adatai alapján elemeztük a borral kapcsolatos utazási hajlandóságot és preferenciákat. Az online kérdőíves felmérés keretében 8552 fő borturizmussal kapcsolatos válaszait vizsgáltuk, majd az utazási gyakoriság alapján három csoportot elemeztünk részletesen: a rendszeres utazókat, akik legalább évente vesznek részt borral kapcsolatos utazáson, a ritkábban utazókat, akik ennél ritkábban utaznak ilyen céllal, és a nyitottakat, akik még soha nem voltak ilyen úton, de szívesen részt vennének valamikor.
LEGFONTOSABB EREDMÉNYEK
Válaszadóink magas érdeklődést mutattak a borhoz köthető utazással kapcsolatban. Azt tapasztaltuk, hogy eltérések vannak az utazási gyakoriság alapján létrejött csoportok között a borvidék kiválasztása, és a konkrét borászat kiválasztása terén is. A rendszeres utazók nyitottabbak a kevésbé ismert borvidékek irányába, mint a ritkábban utazók. A borászattal kapcsolatos elvárásaik terén is igényesebbek, a borászat által nyújtott élmény (például hangulat, szolgáltatások, étkezés) erőteljesebben jelenik meg körükben, mint a többi csoportnál. A ritkábban utazók, illetve a nyitottak csoportja az ismert borvidékeket látogatná szívesen, és számukra a döntést erőteljesebben befolyásolja, hogy a környéken milyen egyéb látnivalók és programok érhetőek el.
GYAKORLATI JAVASLATOK
Kutatásunk rávilágított arra, hogy a látogatók számára a helyszín (hangulat, vendégtér, kiegészítő szolgáltatások stb.), étkezési lehetőségek, borász jelenléte is meghatározó szerepet játszik a pincészet kiválasztásánál, vagyis a borturisták komplex élményt keresnek. A borászatnak tehát érdemes szolgáltatáscsomagot kialakítani. Hasznos lehet más piaci szereplőkkel együttműködni (például az étkezési és szálláslehetőség tekintetében), és ezt eleve felkínálni az érdeklődőknek. A desztinációknak is figyelembe kell venniük, hogy az utazók nagy része (mintánk háromnegyede) egy hétvégét, 2-3 napot töltene borhoz kapcsolódó utazással, tehát programcsomagot érdemes ajánlani számukra. Miután a borvidék ismertsége és pincészetei mellett ugyanúgy fontosak a látnivalók, programlehetőségek, események, így utóbbiakat javasolt fejleszteni, illetve összehangolni.
Köszönetnyilvánítás: A Nagy Bor Teszt kutatás 2018-ban a Winelovers, a Magyar Turisztikai Ügynökség, a Vinoport, a Borászportál, valamint a Borkollégium támogatásával készült.
Overlooked Tertiary Sulci Serve as a Meso-Scale Link between Microstructural and Functional Properties of Human Lateral Prefrontal Cortex

Published: January 2021

Understanding the relationship between neuroanatomy and function in portions of cortex that perform functions largely specific to humans such as lateral prefrontal cortex (LPFC) is of major interest in systems and cognitive neuroscience. When considering neuroanatomical–functional relationships in LPFC, shallow indentations in cortex known as tertiary sulci have been largely unexplored. Here, by implementing a multimodal approach and manually defining 936 neuroanatomical structures in 72 hemispheres (in both males and females), we show that a subset of these overlooked tertiary sulci serve as a meso-scale link between microstructural (myelin content) and functional (network connectivity) properties of human LPFC in individual participants. For example, the posterior middle frontal sulcus (pmfs) is a tertiary sulcus with three components that differ in their myelin content, resting-state connectivity profiles, and engagement across meta-analyses of 83 cognitive tasks. Further, generating microstructural profiles of myelin content across cortical depths for each pmfs component and the surrounding middle frontal gyrus (MFG) shows that both gyral and sulcal components of the MFG have greater myelin content in deeper compared with superficial layers and that the myelin content in superficial layers of the gyral components is greater than sulcal components. These findings support a classic, yet largely unconsidered theory that tertiary sulci may serve as landmarks in association cortices, as well as a modern cognitive neuroscience theory proposing a functional hierarchy in LPFC. As there is a growing need for computational tools that automatically define tertiary sulci throughout cortex, we share pmfs probabilistic sulcal maps with the field.SIGNIFICANCE STATEMENTLateral prefrontal cortex (LPFC) is critical for functions that are thought to be specific to humans compared with other mammals. However, relationships between fine-scale neuroanatomical structures largely specific to hominoid cortex and functional properties of LPFC remain elusive. Here, we show that these structures, which have been largely unexplored throughout history, surprisingly serve as markers for anatomical and functional organization in human LPFC. These findings have theoretical, methodological, developmental, and evolutionary implications for improved understanding of neuroanatomical–functional relationships not only in LPFC, but also in association cortices more broadly. Finally, these findings ignite new questions regarding how morphological features of these neglected neuroanatomical structures contribute to functions of association cortices that are critical for human-specific aspects of cognition.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a multisystemic disease that mainly affects the lungs and skin. It is considered to be a small and medium-vessel vasculitis. Although neurologic manifestations of EGPA are reported, usually consisting of peripheral neuropathy, central nervous system manifestations are quite rare, those described being cerebral infarctions or hemorrhages.
We present the case of a 79-year-old woman diagnosed in 2016 with EGPA, being treated with Prednisone and Azathioprine, who presented to the Neurological Emergency Department with right hemiplegia, dysmetria in the left arm and right hemi-hypoesthesia. CT (computed tomography) and MRI (Magnetic resonance imaging) findings on admission described lacunar strokes. The patient presented with low creatinine clearance on admission (positive for chronic renal disease), grade III hypertension, ischemic cardiomyopathy and right calf deep vein thrombosis. The patient was started on neuroprotective and neurotrophic treatment associated with parenteral hydration, anticoagulant and hypotensive drugs . The patient’s symptoms partially improved, with possibility of independently maintaining a sitting position and upright stance with unilateral sustenance at discharge.
Patients suffering from vasculitides must be carefully observed in order to prevent or treat complications that may emerge.

OBJECTIVES:
To describe neonatal and maternal characteristics of the largest prospective cohort of newborns from mothers with coronavirus disease 2019 (COVID-19), the data of which were prospectively collected from the nationwide registry of the Spanish Society of Neonatology.

METHODS:
Between March 8, 2020, and May 26, 2020, the data of 503 neonates born to 497 mothers diagnosed with COVID-19 during pregnancy or at the time of delivery were collected by 79 hospitals throughout Spain.

RESULTS:
Maternal symptoms were similar to that of the general population, with 5% of severe forms. In 45.8% of asymptomatic women at the time of delivery, severe acute respiratory syndrome coronavirus 2 infection was detected because of recommendations established in Spain to perform COVID-19 screening in all women admitted to the hospital for labor. The rate of preterm deliveries was 15.7% and of cesarean deliveries, 33%. The most common diagnostic test was detection of viral RNA by polymerase chain reaction of nasopharyngeal swabs at a median age of 3 hours after delivery (1–12 hours). Almost one-half of neonates were left skin-to-skin after delivery, and delayed clamping of umbilical cords was performed in 43% of neonates. Also, 62.3% of asymptomatic neonates were managed with rooming-in. Maternal milk was received by 76.5% of neonates, 204 of them as exclusive breastfeeding.

CONCLUSIONS:
The current study indicates that there is no need for separation of mothers from neonates, allowing delayed cord clamping and skin-to-skin contact along with maintenance of breastfeeding in a high percentage of newborns from mothers with COVID-19.
Analytical construction of the projectile motion trajectory in midair
Authors: Chudinov Peter , Eltyshev Vladimir , Barykin Yuri 
Published: January 2021

A classic problem of the motion of a projectile thrown at an angle to the horizon is studied. Air resistance force is taken into account with the use of the quadratic resistance law. An analytic approach is mainly applied for the investigation. Equations of the projectile motion are solved analytically for an arbitrarily large period of time. The constructed analytical solutions are universal, that is, they can be used for any initial conditions of throwing. As a limit case of motion, the vertical asymptote formula is obtained. The value of the vertical asymptote is calculated directly from the initial conditions of motion. There is no need to study the problem numerically. The found analytical solutions are highly accurate over a wide range of parameters. The motion of a baseball, a tennis ball, and a shuttlecock of badminton are presented as examples.
LA CIVILIZACIÓN DE LOS CUERPOS: LAS PEDAGOGÍAS SEXUALES Y DE GÉNERO EN LA EDUCACIÓN PRIMARIA COSTARRICENSE
Authors: Gamboa Barboza María Isabel 
Published: January 2021

Tras un análisis de discurso y con el objeto de estudiar los mecanismos disciplinares de las sexualidades y los géneros existentes en los programas de la educación primaria costarricense, se sugiere que estos son producto de dos tendencias discursivas: una liberal y otra conservadora. A diferencia de los hallazgos de una investigación que se realizó anteriormente, con programas producidos a lo largo de más de cuatro décadas, en la que predominó un tipo de rechazo a la diversidad sexual, en los actuales, el conservadurismo tiene untinte especialmente misógino.

An Audacious Argument for Modesty
Authors: Bérubé Michael 
Published: January 2021

It is notable that Pardis Dabashi's paper at the 2019 MLA convention, “the pressure to intervene: A case for the modest (Young) Critic,” caused such a stir—insofar as it mounted a gentle argument against ritual stir-causing, and the gentleness of the argument was central to its point. As Dabashi wrote, “the language of the scholarly intervention—that is, the articulation of the stakes of one's argument—has a way of ossifying hunches into convictions” (4). The idea, clearly, was to ratchet down the level of agon and hubris in scholarly debate and to foreground the perspectives of younger scholars making their first forays into the fray: “since thus far the post-critical debates held in widely circulated and visible academic forums have mostly been conducted among professionally secure, mid-late career scholars, we've not yet had the chance to discuss the kind of epistemic modesty that matters very deeply to early-career-stage scholars now, that is, scholars entering graduate programs in or around 2008” (2). Dabashi suspects, at least as this professionally secure, mid-to-late-career scholar hears her, that the cohort entering the desiccated post-2008 (and especially post-2015) job market does not see the profession in the terms that have dominated debate about the purpose of criticism over the past ten or twelve years:The field of critical production for us is deeply heterogenous, syncretic: the mixing of critical and (at least some) postcritical methods has become something we take for granted. And early-career scholars of this generation—who don't really have a horse in the race of re-orientating ourselves vis-à-vis the text—would advocate instead, it seems to me, for re-orienting ourselves vis-à-vis each other—that is, laterally, scholar to scholar.

Composición florística y aspectos de la estructura de la vegetación en sistemas agroforestales con cacao (Theobroma cacao L. - Malvaceae) en el departamento del Huila, Colombia
Authors: Mercedes Ordoñez Claudia , Rangel-Ch J. Orlando 
Published: January 2021

Con base en la composición florística y en aspectos de la estructura (área basal y número de individuos), se caracterizó la vegetación en sistemas agroforestales (SAF) ubicados en 47 plantaciones con cacao (Theobroma cacao) en el departamento del Huila, Colombia. La vegetación en dichos sistemas estaba dominada por las especies Pseudosamanea guachapele, Musa paradisiaca, Erythrina poeppigiana, Gmelina arborea, Psidium guajava, Manguifera indica y Cordia alliodora. Las especies aracterísticas-dominantes a nivel regional fueron Gliricidia sepium, Cordia alliodora, Amyris pinnata y Persea americana. Los sistemas agroforestales con mayor riqueza fueron el de Pseudosamanea guachapele, con 36 especies y el de Musa paradisiaca, con 25. La altura de los individuos oscilaba entre 3 y 21 m, y el mayor valor se presentó en el sistema de P. guachapele; el área basal fue 64,30 m2, los mayores valores se registraron en los sistemas agroforestales de P. guachapele, con 16.41 m2 y en el de E. poeppigiana, con 18,03 m2. La participación de T. cacao a nivel regional en el área basal es de 56,63 m2 y el número total de individuos es de 4.808. En los sitios con exposición libre (cultivo limpio en 11.000 m2) la altura promedio de los individuos de cacao era de 3,5 m, el área basal, de 15,31 m2, con 1.101 individuos. Esta cantidad es casi igual a la que se encontraría en un área de igual extensión en el sistema agroforestal bajo sombra de P. guachapele (1.386 individuos) y cinco veces mayor que aquel con presencia de todas las especies asociadas pero sin T. cacao (217 individuos). Aparte de la cosecha de cacao, estos sistemas ofrecen madera, frutos y leña, y proveen servicios ecosistémicos relacionados con la protección del suelo y la conservación de la biodiversidad.

A pesar de la importancia ecológica y económica de la Orinoquía colombiana, aún son escasos los studios básicos sobre la vegetación, los cuales se requieren para planificar el manejo y la conservación de la flora de esta región. El objetivo de este estudio fue analizar la riqueza, composición y distribución geográfica de las plantas vasculares de la cuenca baja del río Pauto (Casanare-Colombia). Se hicieron muestreos de la vegetación durante las temporadas de sequía y lluvias en cuadrantes de 1x1 m en las sabanas y en parcelas de 50x20 m en los bosques, incluyendo áreas con transformación antropogénica. e registraron 701 especies, 421 géneros y 121 familias en un catálogo sistemático; 52 de las especies no se habían registrado previamente en la flora de la Orinoquía. En las sabanas, las familias con mayor riqueza fueron Leguminosae sensu lato (43), Cyperaceae (42) y Poaceae (38); y en los bosques, Leguminosae sensu lato (49), Malvaceae y Rubiaceae (26 cada una). Las formas de crecimiento con más especies fueron las hierbas (294), seguidas de árboles (129) y sufrútices (111). La mayoría de las especies están ampliamente distribuidas en el Neotrópico y muchas se encuentran en las selvas húmedas, bosques secos y sabanas de Suramérica. En el futuro es necesario incrementar los muestreos en sabanas y en el estrato herbáceo de los bosques ribereños, así como los esfuerzos de categorización de las amenazas de la flora regional de la Orinoquía.

The phenomena of increasing total IgE level in Soil Transmitted Helminthiasis and its protective role in resistance of infection remains unclear. The purpose of this study was to determine the correlation between total IgE and the intensity of Soil transmitted helminthiasis among farmers in these area. Total 162 farmer, age ranged 25-80 years participated in this cross sectional analytic study. Kato-Katz method was used to diagnose Soil Transmitted Helminthiasis and to determined infection intensity based on egg per gram (EPG). Total IgE levels were measured by enzyme linked flourescent assay (ELFA). The results of this study showed that 13,56% farmer positive for Soil Transmitted Helminthiasis, with single infection of Ascaris lumbricoides were 1,85%, 9,26% for Trichuris trichiura, 0,61% for Hookworm and mixed infection that were 1,23% for A.lumbricoides+T.trichiura 0,61% for A.lumbricoides+Hookworm. The intensity of infection were in mild category. Total IgE level in Soil transmitted Helminthiasis group was significantly different compared with noninfected group (p<0.05, t-test). There was significant correlation between EPG and total IgE level (r=0.667, p=0.001, Spearman test). As a conclusion total IgE level was significantly correlated with EPG, this fact can be used to develop management of Soil Transmitted Helminthiasis theraphy.
Effect of Different Complementary Feeding on Iron Deficiency Anemia and Growth in Breastfed Infants: Home-Made VS Commercial

Published: January 2021

After approximately 6 months of age, term breastfed infants are increasingly depend on other sources of iron to avoid iron deficiency anemia, due to the depletion of the low concentration of iron in human milk. The appropriate complementary feeding must include a balance composition of foods containing an adequate amount of macro- and micronutrients to avoid iron deficiency anemia. This study aimed to compare the risk of iron deficiency and growth in breastfeed infants receiving commercial fortified complementary foods or home-made. A cross-sectional study was held on April-June 2016 to evaluate infants aged 6-24 months with breast feeding intake for 6 month of life. Complementary feeding practices were determined by questionnaire; an unquantified food frequency and feeding practices questionnaire was used to determine usual food intake. Biochemical assessment of haemoglobin (Hb), serum ferritin (SF) and serum iron (SI) level were measured. Anthropometric were assessed using WHO Child Growth Standard 2005. Statistical analysis used were Chi-square Test. Thirty eight infants were enrolled, mean age of 16.2 (SD 10.5) months. 17 infants consumed commercial complementary foods and 21 infants use home-made. Infants with home-made had lower Hb level, SF and SI than those receiving commercial complementary food, and had higher risk of underweight, stunted and wasted. Infants with home-made complementary food had lower haemoglobin, serum feritin and serum iron levels than those in fortified complementary food CF; and a higher risk of stunted and wasted than children with commercial fortified CF.
