Published: January 2021

Der unternehmensübergreifende Datenaustausch in der Welt von Industrie 4.0 birgt für Unternehmen immense Potenziale. So können Unternehmen wertvolles Wissen über den Einsatz ihrer Produkte gewinnen und ihren Kunden innovative Dienstleistungen anbieten. Umgekehrt können Kunden die Produkte zielgerichteter einsetzen, wenn sie beispielsweise Produktions- und Materialdetails kennen. Doch dabei möchte kein Unternehmen für sich geschäftskritisches Wissen an einen Partner im Wertschöpfungsnetzwerk freigeben. Zu groß ist das Risiko, Einblicke in beispielsweise Forschungs- und Entwicklungsergebnisse zu gewähren oder dem Kunden eine Kostenkalkulation aufgrund des genauen Prozessablaufes zu ermöglichen. Es ergibt sich die Frage, welche Daten bedenkenlos ausgetauscht werden können und in welchen Daten implizit wertvolles Wissen enthalten ist. Aus diesem Grund stellt der vorliegende Beitrag ein Vorgehensmodell zur Identifikation von schützenswertem Wissen vor dem Hintergrund des unternehmensübergreifenden automatisierten Datenaustauschs von Maschinen über Netzwerkplattformen vor. Mit Hilfe des Modells lassen sich Daten und Wissen analysieren und auf Basis der Schutzbedarfe und enthaltenen Potenziale einstufen. Ein möglichst umfangreicher unternehmensübergreifender Datenaustausch bei möglichst geringem Verlust von Know-how soll ermöglicht werden. Anschließend wird die Erprobung des Modells im Rahmen eines Anwendungsbeispiels vorgestellt und ein Ausblick gegeben.
Partial cortico-hippocampectomy in cats, as therapy for refractory temporal epilepsy: A descriptive cadaveric study
Authors: Zilli Jessica , Kressin Monika , Schänzer Anne , Kampschulte Marian , Schmidt Martin J.
Published: January 2021

Cats, similar to humans, are known to be affected by hippocampal sclerosis (HS), potentially causing antiepileptic drug (AED) resistance. HS can occur as a consequence of chronic seizure activity, trauma, inflammation, or even as a primary disease. In humans, temporal lobe resection is the standardized therapy in patients with refractory temporal lobe epilepsy (TLE). The majority of TLE patients are seizure free after surgery. Therefore, the purpose of this prospective cadaveric study is to establish a surgical technique for hippocampal resection in cats as a treatment for AED resistant seizures. Ten cats of different head morphology were examined. Pre-surgical magnetic resonance imaging (MRI) and computed tomography (CT) studies of the animals’ head were carried out to complete 3D reconstruction of the head, brain, and hippocampus. The resected hippocampal specimens and the brains were histologically examined for tissue injury adjacent to the hippocampus. The feasibility of the procedure, as well as the usability of the removed specimen for histopathological examination, was assessed. Moreover, a micro-CT (mCT) examination of the brain of two additional cats was performed in order to assess temporal vasculature as a reason for possible intraoperative complications. In all cats but one, the resection of the temporal cortex and the hippocampus were successful without any evidence of traumatic or vascular lesions in the surrounding neurovascular structures. In one cat, the presence of mechanical damage (a fissure) of the thalamic surface was evident in the histopathologic examination of the brain post-resection. All hippocampal fields and the dentate gyrus were identified in the majority of the cats via histological examination. The study describes a new surgical approach (partial temporal cortico-hippocampectomy) offering a potential treatment for cats with clinical and diagnostic evidence of temporal epilepsy which do not respond adequately to the medical therapy.
Patient-reported outcomes for diabetes and hypertension care in low- and middle-income countries: A scoping review
Authors: Masyuko Sarah , Ngongo Carrie J. , Smith Carole , Nugent Rachel
Published: January 2021

Introduction

Patient-reported outcome measures (PROMs) assess patients’ perspectives on their health status, providing opportunities to improve the quality of care. While PROMs are increasingly used in high-income settings, limited data are available on PROMs use for diabetes and hypertension in low-and middle-income countries (LMICs). This scoping review aimed to determine how PROMs are employed for diabetes and hypertension care in LMICs.

Methods

We searched PubMed, EMBASE, and ClinicalTrials.gov for English-language studies published between August 2009 and August 2019 that measured at least one PROM related to diabetes or hypertension in LMICs. Full texts of included studies were examined to assess study characteristics, target population, outcome focus, PROMs used, and methods for data collection and reporting.

Results

Sixty-eight studies met the inclusion criteria and reported on PROMs for people diagnosed with hypertension and/or diabetes and receiving care in health facilities. Thirty-nine (57%) reported on upper-middle-income countries, 19 (28%) reported on lower-middle-income countries, 4 (6%) reported on low-income countries, and 6 (9%) were multi-country. Most focused on diabetes (60/68, 88%), while 4 studies focused on hypertension and 4 focused on diabetes/hypertension comorbidity. Outcomes of interest varied; most common were glycemic or blood pressure control (38), health literacy and treatment adherence (27), and acute complications (22). Collectively the studies deployed 55 unique tools to measure patient outcomes. Most common were the Morisky Medication Adherence Scale (7) and EuroQoL-5D-3L (7).

Conclusion

PROMs are deployed in LMICs around the world, with greatest reported use in LMICs with an upper-middle-income classification. Diabetes PROMs were more widely deployed in LMICs than hypertension PROMs, suggesting an opportunity to adapt PROMs for hypertension. Future research focusing on standardization and simplification could improve future comparability and adaptability across LMIC contexts. Incorporation into national health information systems would best establish PROMs as a means to reveal the effectiveness of person-centered diabetes and hypertension care.

Derechos de propiedad, compañías petroleras, Estado y renta en Venezuela
Authors: Mora Contreras Jesús
Published: January 2021

RESUMEN: Este artículo muestra que las compañías petroleras internacionales han estado haciendo negocios en Venezuela durante más de cuatro quintas partes de casi un siglo de historia de la industria petrolera en este país (1917-2009). Muestra también que lo que ha cambiado para ellas a lo largo del tiempo es la manera de hacer negocios en la industria petrolera venezolana, valga decir, los términos y condiciones de acceso a las actividades de exploración y producción que les ha impuesto el propietario del recurso natural, relacionados particularmente con el reparto de la renta petrolera internacional. El artículo, dividido en cuatro secciones, es una síntesis de la historia del derecho de propiedad del subsuelo, de las compañías petroleras, del Estado y de la renta petrolera internacional en Venezuela desde 1920 hasta el presente. ABSTRACT: This paper shows that in almost a century of history of the Venezuelan oil industry (1917-2009), International Oil Companies (IOCs) have been doing business in this country for just more than fourth fifth of this period (74/92 years). It shows too that during that time, what has been changing in this country for the oil companies, IOCs or National Oil Companies (NOCs), is the way of doing business in the upstream of the oil industry: the terms and conditions of the owner of the underground property rights. Terms and conditions mean in this context how much of the oil generated rents in the underground public and national property rights goes to the pockets of the oil companies and government. This paper summarizes the history of the underground property rights, oil companies, the State, and rent in Venezuela from 1920 up to the present.
Migraciones trasatlánticas y globalización: brasileños en tierras lusas y el poder de las redes sociales
Authors: Padilla Beatriz
Published: January 2021

El objetivo de este texto es contextualizar la inmigración latinoamericana a Portugal, que presenta características de diversos sistemas migratorios (ibérico, latinoamericano, lusófono) usando como ejemplo el caso de los brasileños. Este caso revela, por un lado, la compleja relación que Brasil y Portugal tienen como consecuencia de las antiguas relaciones coloniales y de las múltiples migraciones en ambos sentidos; y, por otro, la influencia y modus operandi de las redes sociales a partir de una etnografía multisituada en origen y destino. El análisis de los flujos y de su inserción en el mercado de trabajo y de las redes sociales permite abordar el doble entorno de las migraciones ilustrando el papel que juegan dichas redes en la integración de los brasileños en la sociedad de acogida. El abordaje a las redes sociales asume múltiples facetas que incluyen la informalidad/formalidad de las mismas, las diferencias de género y las formas de solidaridad y reciprocidad étnica.
Sociedad civil y poder político en República Dominicana
Authors: Espinal Rosario , Morgan Jana , Hartlyn Jonathan
Published: January 2021

República Dominicana registra un alto nivel de asociacionismo social y activismo político en el contexto latinoamericano. Esto, sin embargo, no se ha traducido en mayor capacidad de la sociedad civil dominicana para reformar el sistema político y mejorar la democracia. Con este planteamiento de fondo, se exploran dos preguntas. La primera es si existe una tendencia a la coparticipación en las organizaciones sociales y políticas que reduce la capacidad de presión de la sociedad civil sobre los partidos y el Estado. La segunda refiere a la naturaleza del vínculo de los participantes en organizaciones de la sociedad civil con el Estado y los partidos. El análisis muestra el involucramiento de un segmento de participantes en actividades cívicas, también en actividades partidarias y en redes clientelares.
La contingencia de la independencia y de la revolución: perspectivas teóricas y comparadas sobre América latina
Authors: Knöbl Wolfgang
Published: January 2021

Este artículo compara las revoluciones francesa y estadounidense del último tercio del siglo XVIII con la independencia y la revolución en la América Latina de inicios del siglo XIX, bajo una perspectiva teórica particular. Centrándose principalmente en las etapas iniciales de estos eventos revolucionarios, se demostrará que a) en los tres casos, el camino hacia un quiebre revolucionario con el viejo régimen no fue predeterminado y b) particularmente en las Américas, el tema de la Nación no fue del todo resuelto por los revolucionarios. Ésta es una de las explicaciones más importantes de por qué, en adelante, la construcción de la Nación –y del Estado– en América Latina y Norteamérica no fue un proceso cómodo ni linear.
«Sexilios»: hacia una nueva poética de la erótica caribeña
Authors: Martínez-san Miguel Yolanda
Published: January 2021

Tomando como punto de partida las definiciones de sexilio que manejan los críticos de estudios sobre la sexualidad en el Caribe y los estudiantes de subgrado estadounidense, este ensayo estudia el exilio de las minorías sexuales en Puerto Rico y Cuba. Este estudio se enfoca en el sexilio de personajes masculinos y analiza cómo Luis Rafael Sánchez, Reinaldo Arenas y Manuel Ramos Otero representan la definición tradicional del sexilio para explorar de qué maneras puede transformarse esta noción al añadírsele la acepción que aportan las nuevas generaciones de estudiantes de subgrado. El ensayo concluye entonces evaluando las ventajas y desventajas de proponer el sexilio como una poética de la erótica caribeña que redefine los discursos sobre identidad colectiva en el Caribe.
La consolidación democrática en Paraguay
Authors: Fretes Carreras Luis Antonio
Published: January 2021

Este trabajo pretende identificar las debilidades y mutaciones del proyecto de transición iniciado en el Paraguay con el golpe militar de 1989, así como también señalar aquellos elementos que a lo largo de veinte años permitieron la continuidad de las estructuras y las prácticas autoritarias originadas en la dictadura. Que la victoria y el advenimiento del gobierno de la Alianza Patriótica para el Cambio (APC) en el 2008 significan una ruptura con las bases de la transición y alteraron el rumbo del proceso político transformando los espacios estratégicos de disputa e incorporando nuevas temáticas y actores. Esta descripción pretende afirmar que el proceso político del Paraguay es un caso que demuestra como los cambios constitucionales, la implantación de nuevas instituciones y sanción de singulares normas de contenido democrático no implican automáticamente el fin de la transición de un régimen autoritario hacia otro democrático y el advenimiento de su consolidación.
Análisis organizacional del Partido de la Democracia Social Brasileña en el estado de San Pablo (1988-2006)
Authors: Miceli Kerbauy María Teresa , AssumpçÃo Raiane
Published: January 2021

El artículo representa un enfoque teórico-metodológico para el análisis de la dinámica organizacional de los partidos políticos en la actualidad, a partir de una investigación realizada sobre el Partido de la Democracia Social Brasileña (PSDB) en el estado de San Pablo (periodo entre 1988 hasta 2006). Se partió de la hipótesis de que la estructura y las normas institucionales de determinado partido, o incluso sus resultados electorales, son insuficientes tanto para explicar el funcionamiento interno, como el papel de la organización partidaria en el sistema político electoral. Mediante un enfoque que articula los patrones de relaciones, los resultados electorales y la ocupación de cargos partidarios, se identificaron los factores que explican el capital político que circuló en el interior del partido y garantizó su dinámica organizacional a lo largo del periodo analizado.

How to Represent Abstract Concepts? From the Perspective of Conceptual Metaphor Theory
Authors: Huang Yanli
Published: January 2021

How human understand and represent concepts is always a hot topic in cognitive psychology. According to the conceptual metaphor theory 1, 2, understanding and representing abstract concepts rely on concrete concepts via metaphoric mappings. In this review, we discussed three core issues with the aim to have a comprehensive understanding of conceptual metaphors. First, I describe the underlying process of metaphoric mappings. Lakoff and Johnson (1999) 2 put forward that the source domain (concrete concepts) can be used to represent the target domain (abstract concepts). The metaphoric mappings from source domains to target domains are characterized as image schemas, which structure and provide sensory-motor grounding for abstract concepts. Then, I concerned on the directionality (the second issue) and automaticity (the third issue) of metaphoric mappings. According to conceptual metaphor theory, metaphoric mappings have the directionality from the concrete domain to the abstract domain, which is an automatic and obligatory process with neither effort nor awareness. However, directionality and automaticity were debated by recent research. In this article, by focusing on the three important issues I provided a comprehensive review which would help deepen our understanding about the nature of metaphoric mappings.
HEAT TRANSFER ENHANCEMENT AND FRICTION IN DOUBLE PIPE HEAT EXCHANGER WITH VARIOUS NUMBER OF LONGITUDINAL GROOVES
Authors: Sunu Putu Wijaya , Anakottapary Daud Simon , Suarta I Made , Santosa I Dewa Made Cipta , Suarsana Ketut
Published: January 2021

It has been found out that heat exchangers with longitudinal grooves produce better heat transfer than those without longitudinal grooves. However, up to now, there have been few investigations and applications of longitudinal grooves in relation to heat transfer associated with friction from the annulus of a heat exchanger. The present investigation examined the effects of longitudinal grooves in a double pipe heat exchanger on the characteristics of heat transfer and friction. Longitudinal rectangular grooves were carved into the outer side of a tube at a specified depth (t) and width (l). The effect of the number of longitudinal grooves, Reynolds number (Re), on the thermal and hydraulic performance was evaluated based on the heat exchanger experimental data. A total of four pipes were used: one pipe with 2 grooves, one pipe with 4 grooves, one pipe with 6 grooves and one pipe with 8 grooves. Water, hot and cold, was used as the working fluid. The test was performed with the cold water as the working fluid, with the Reynolds number from about 33 000 to 46 000 in a counter-flow scheme. The result showed that the number of grooves improved the heat transfer and caused a pressure drop. The increase in heat transfer ranged from 1.05 to 1.15, and the pressure loss of the system reached almost 30% as compared with the smooth annulus, the annulus with no groove. The installation of longitudinal grooves in a heat exchanger system enhanced the process of the heat flow through the boundary but provided a compensation for the pressure loss, which was correlated with the friction and pumping power.

Lay Definitions of Cultural Appropriation in U.S. Community and College Student Samples
Authors: Katzarska-Miller Iva , Faucher Ford , Kramer Lilly , Reysen Stephen
Published: January 2021

In three studies we examined lay definitions of cultural appropriation in U.S. community and college student samples. In a fourth study we examined correlates of perceptions of cultural appropriation. Using community and undergraduate student samples (Studies 1-2), and popular media articles (Study 3) we examined definitions of cultural appropriation following Rogers’ (2006) typology of cultural exchange, dominance, and subordination. The results across three studies revealed that cultural appropriation was defined predominantly as cultural exploitation. In Study 4 we examined political correctness (emotion and activism), social justice, empathy (perspective taking and empathic concern), and political orientation as correlates of cultural appropriation perceptions. Using canonical correlations, we found that cultural exploitation was the primary contributor to the synthetic predictor, and political orientation, emotion political correctness, activism political correctness, and social justice made significant contributions to the criterion variable, but not empathy. Implication and further research directions are discussed.
Do Tunisian Universities need organizational commitment?
Authors: HAJRI Mehdi
Published: January 2021

Higher Education is a real lever of growth for developing countries such as Tunisia. The aim of our study is to show the importance of organizational commitment in the intention of running the university well.

As a result, the review of the literature enabled us to analyze a concept of attitude at work, namely organizational commitment, which in our opinion can constitute a major lever for carrying out the university development strategies.

It has been established that academics remain committed to their vocation and thereby demonstrate their continued commitment to their students despite the workload, administrative tasks and research carried out (Houston et al., 2006).

Published: January 2021

Administration is a tool that helps to improve the internal issues of any institution as long as they are used correctly and effectively to address the areas of opportunity that may exist. The research aims to prove that proper management can help develop useful competencies for university students entering the world of work. The methodology implemented is quantitative in nature, using the survey technique. The universe studied was 72 students, considering a convenience sample due to the very small number of the population, since the main purpose is to corroborate or refute the proposed hypothesis where it is said that the Faculty of Engineering of the Amazcala Campus carries out its administration efficiently to verify that the teachers develop in the students the necessary labor competencies for their graduation to the professional field. Among the most important results, it was found that administrative management must communicate the agreements that are made and verify that students are acquiring the necessary knowledge for the professional field.

CTRP9 protects against MIA-induced inflammation and knee cartilage damage by deactivating the MAPK/NF-κB pathway in rats with osteoarthritis
Authors: Zheng Shicheng , Ren Jing , Gong Sihai , Qiao Feng , He Jinlong
Published: January 2021

C1q/TNF-related protein 9 (CTRP9), the closest paralog of adiponectin, has been reported to protect against inflammation-related diseases. However, its role in regulating osteoarthritis (OA) has not been fully elucidated. First, a rat model of OA was generated. Furthermore, rats with OA were injected with different doses of recombinant CTRP9 protein (rCTRP9), and the knee cartilage damage was evaluated. Finally, the phosphorylation of p38 and the secretion of matrix metalloproteinases (MMPs) were detected by Western blotting and enzyme-linked immunosorbent assay. Results revealed that CTRP9 was highly expressed in adipose tissue, followed by skeletal muscle and cartilage tissue, and less expressed in liver, kidney and lung. Moreover, the expression of CTRP9 significantly decreased in the monosodium iodoacetate (MIA) group in the knee cartilage and knee synovial fluid, and the contents of interleukin-1β (IL-1β) and IL-6 significantly increased in knee synovial fluid. In addition, rCTRP9 alleviated MIA-induced inflammation, oxidative stress and knee cartilage damage in a dose-dependent way. In addition, rCTRP9 could attenuate the expression of p38MAPK and p-p38 and suppress the expression of nuclear factor-kappa B (NF-κB), p65 and MMPs. Collectively, the results of the present study suggested that CTRP9 alleviates the inflammation of MIA-induced OA through deactivating p38MAPK and NF-κB signaling pathways in rats.
Thermal Stress Development in Low Dimensional Silicon Film: An Analytical Approach
Authors: Yilbas Bekir Sami , Alassar R. S. M. , Al-Dweik Ahmad Y.
Published: January 2021

Thermal excitation of the low dimensional silicon film is introduced and an analytical approach is adopted for the solution of the transport equation. In the analysis, the phonon radiative transport equation is converted into an integral form of the Fredholm equation of the second kind. The analytical approach is extended to include the formulation of thermal stresses for the following cases: (i) stress-free at the edges and (ii) one edge is constrained to have maximum stress while the other edge is set to be stress-free. The analytical and numerical results are evaluated for comparisons. The findings demonstrate that both results are in good agreement. The dimensionless temperature rise at the film mid-thickness becomes sharp for small thickness film. The peak value of thermal stress at the film mid-thickness becomes larger as the film thickness is reduced further. Stress waves generated initially are compressive at the film mid-thickness and they become tensile at both ends of the stress-free film, which becomes more apparent as time increases. Two consecutive compressive and tensile stresses are generated at the mid-thickness of the film as the stress boundary condition is changed to the maximum stress at one edge of the film.
Mathematical models for information classification and recognition of multi-target optical remote sensing images
Authors: Zhang Haiqing , Han Jun
Published: January 2021

Traditionally, three-dimensional model is used to classify and recognize multi-target optical remote sensing image information, which can only identify a specific class of targets, and has certain limitations. A mathematical model of multi-target optical remote sensing image information classification and recognition is designed, and a local adaptive threshold segmentation algorithm is used to segment multi-target optical remote sensing image to reduce the gray level between images and improve the accuracy of feature extraction. Remote sensing image information is multi-feature, and multi-target optical remote sensing image information is identified by chaotic time series analysis method. The experimental results show that the proposed model can effectively classify and recognize multi-target optical remote sensing image information. The average recognition rate is more than 95%, the maximum robustness is 0.45, the recognition speed is 98%, and the maximum time-consuming average is only 14.30 s. It has high recognition rate, robustness, and recognition efficiency.
Analytical solution of one-dimensional Pennes’ bioheat equation
Authors: Wang Hongyun , Burgei Wesley A. , Zhou Hong
Published: January 2021

Pennes’ bioheat equation is the most widely used thermal model for studying heat transfer in biological systems exposed to radiofrequency energy. In their article, “Effect of Surface Cooling and Blood Flow on the Microwave Heating of Tissue,” Foster et al. published an analytical solution to the one-dimensional (1-D) problem, obtained using the Fourier transform. However, their article did not offer any details of the derivation. In this work, we revisit the 1-D problem and provide a comprehensive mathematical derivation of an analytical solution. Our result corrects an error in Foster’s solution which might be a typo in their article. Unlike Foster et al., we integrate the partial differential equation directly. The expression of solution has several apparent singularities for certain parameter values where the physical problem is not expected to be singular. We show that all these singularities are removable, and we derive alternative non-singular formulas. Finally, we extend our analysis to write out an analytical solution of the 1-D bioheat equation for the case of multiple electromagnetic heating pulses.
New emotional model environment for navigation in a virtual reality

Published: January 2021

Emotions are commonly considered to be the most expressive of everyday human experiences, giving a sense of fullness and reality of life. The ability to recognize human emotions as a manifestation of higher intelligence is desirable feature. There are several models of emotional experience that can become the basis for building a universal emotional recognition system. In this article, we check the correctness of the designed emotional model. We check the evaluation of the system’s operation by human observers.
Temporal Prediction Signals for Periodic Sensory Events in the Primate Central Thalamus
Authors: Matsuyama Kei , Tanaka Masaki
Published: January 2021

Prediction of periodic event timing is an important function for everyday activities, while the exact neural mechanism remains unclear. Previous studies in nonhuman primates have demonstrated that neurons in the cerebellar dentate nucleus and those in the caudate nucleus exhibit periodic firing modulation when the animals attempt to detect a single omission of isochronous repetitive audiovisual stimuli. To understand how these subcortical signals are sent and processed through the thalamocortical pathways, we examined single-neuron activities in the central thalamus of two macaque monkeys (one female and one male). We found that three types of neurons responded to each stimulus in the sequence in the absence of movements. Reactive-type neurons showed sensory adaptation and gradually waned the transient response to each stimulus. Predictive-type neurons steadily increased the magnitude of the suppressive response, similar to neurons previously reported in the cerebellum. Switch-type neurons initially showed a transient response, but after several cycles, the direction of firing modulation reversed and the activity decreased for each repetitive stimulus. The time course of Switch-type activity was well explained by the weighted sum of activities of the other types of neurons. Furthermore, for only Switch-type neurons the activity just before stimulus omission significantly correlated with behavioral latency, indicating that this type of neuron may carry a more advanced signal in the system detecting stimulus omission. These results suggest that the central thalamus may transmit integrated signals to the cerebral cortex for temporal information processing, which are necessary to accurately predict rhythmic event timing.

SIGNIFICANCE STATEMENTSeveral cortical and subcortical regions are involved in temporal information processing, and the thalamus will play a role in functionally linking them. The present study aimed to clarify how the paralaminar part of the thalamus transmits and modifies signals for temporal prediction of rhythmic events. Three types of thalamic neurons exhibited periodic activity when monkeys attempted to detect a single omission of isochronous repetitive stimuli. The activity of one type of neuron correlated with the behavioral latency and appeared to be generated by integrating the signals carried by the other types of neurons. Our results revealed the neuronal signals in the thalamus for temporal prediction of sensory events, providing a clue to elucidate information processing in the thalamocortical pathways.

Promoting oligodendrocyte (OL) differentiation represents a promising option for remyelination therapy for treating the demyelinating disease multiple sclerosis (MS). The Wnt effector transcription factor 7-like 2 (TCF7l2) was upregulated in MS lesions and had been proposed to inhibit OL differentiation. Recent data suggest the opposite yet underlying mechanisms remain elusive. Here, we unravel a previously unappreciated function of TCF7l2 in controlling autocrine bone morphogenetic protein (BMP)4-mediated signaling. Disrupting TCF7l2 in mice of both sexes results in oligodendroglial-specific BMP4 upregulation and canonical BMP4 signaling activationin vivo. Mechanistically, TCF7l2 binds toBmp4gene regulatory element and directly represses its transcriptional activity. Functionally, enforced TCF7l2 expression promotes OL differentiation by reducing autocrine BMP4 secretion and dampening BMP4 signaling. Importantly, compound genetic disruption demonstrates that oligodendroglial-specific BMP4 deletion rescues arrested OL differentiation elicited by TCF7l2 disruptionin vivo. Collectively, our study reveals a novel connection between TCF7l2 and BMP4 in oligodendroglial lineage and provides new insights into augmenting TCF7l2 for promoting remyelination in demyelinating disorders such as MS.

SIGNIFICANCE STATEMENTIncomplete or failed myelin repairs, primarily resulting from the arrested differentiation of myelin-forming oligodendrocytes (OLs) from oligodendroglial progenitor cells, is one of the major reasons for neurologic progression in people affected by multiple sclerosis (MS). Usingin vitroculture systems andin vivoanimal models, this study unraveled a previously unrecognized autocrine regulation of bone morphogenetic protein (BMP)4-mediated signaling by the Wnt effector transcription factor 7-like 2 (TCF7l2). We showed for the first time that TCF7l2 promotes oligodendroglial differentiation by repressing BMP4-mediated activity, which is dysregulated in MS lesions. Our study suggests that elevating TCF7l2 expression may be possible in overcoming arrested oligodendroglial differentiation as observed in MS patients.
Primera parte. Del conflicto armado a la paz ambiental. Capítulo 4. Los conflictos ambientales: una desapercibida fuente de desplazamiento en Colombia

En el siglo XXI, las dinámicas derivadas o vinculadas con el medioambiente se configuran como un objeto de estudio por sus implicaciones sobre el desplazamiento forzado, la seguridad alimentaria y el surgimiento de nuevas enfermedades, entre otros. Los desastres naturales, el cambio climático, la crisis del agua y los conflictos ambientales son catalogados como amenazas para la humanidad por organizaciones como el Fondo Económico Mundial y la Organización de las Naciones Unidas. En particular, la degradación y mala gestión de los recursos ha incidido en el surgimiento de estas amenazas. Los países en vía de desarrollo en su propósito de alcanzar un crecimiento económico constante y altos estándares de calidad de vida se han encaminado en la sobreexplotación de sus recursos naturales, ocasionando efectos adversos sobre el medioambiente. Por ejemplo, Colombia, es el segundo país con más biodiversidad en el mundo y a su vez, es el segundo con más conflictos ambientales después de India en el 2016. La extracción de minerales y la explotación de petróleo se han constituido como las principales causas generadoras de estos conflictos.

Sarcoidosis is an inflammatory granulomatous disease that can affect any organ. Up to one-quarter of patients with systemic sarcoidosis may have evidence of cardiac involvement. The clinical manifestations of cardiac sarcoidosis (CS) include heart block, atrial arrhythmias, ventricular arrhythmias and heart failure. The diagnosis of CS can be challenging given the patchy infiltration of the myocardium but, with the increased availability of advanced cardiac imaging, more cases of CS are being identified. Immunosuppression with corticosteroids remains the standard therapy for the acute inflammatory phase of CS, but there is an evolving role of steroid-sparing agents. In this article, the authors provide an update on the diagnosis of CS, including the role of imaging; review the clinical manifestations of CS, namely heart block, atrial and ventricular arrhythmias and heart failure; discuss updated management strategies, including immunosuppression, electrophysiological and heart failure therapies; and identify the current gaps in knowledge and future directions for cardiac sarcoidosis.

A série de televisão Game of Thrones (GoT) se tornou um fenômeno cultural, provocando sua avaliação por fãs da saga literária A Song of Ice and Fire (ASoIaF), na qual é baseada. Assumindo, a partir da teoria foucaultiana, as interações fânicas como práticas discursivas e estas como reveladoras de epistemes, a pesquisa analisa como a produção discursiva de fãs de ASoIaF sobre GoT é epistemicamente fundamentada. O método arqueológico foi aplicado à análise dos comentários produzidos em tais interações ocorridas no principal fórum de fãs de ASoIaF. Os resultados revelam quatro formações discursivas, que vão do reconhecimento à reclamação da adaptação. Elas têm em comum a referência ao cânone literário como balizar de tais avaliações, revelando esta instância como sua base epistêmica. Com base na noção foucaultiana de ordem do discurso, propomos haver uma ordem do cânone que norteia a construção de verdades pelos fãs acerca da transmidiação do universo ficcional.

We improved common metamaterial perfect absorber (MPA) by integrating four embedded inductors or replacing four embedded capacitors in the same compact structure. The obtained results confirmed that the lumped-capacitors MPA maintains an extreme thickness t = λ/940, where λ is operating wavelength at 106.3 MHz. Besides, by replacing these capacitors by inductors in the initial designed-MPA structure, we obtained an effective thickness of t = λ/53 at 1.9 GHz. Furthermore, we explained the absorption mechanism in terms of the magnetic energy and power loss distributions related to the impedance-matching effect.

Published: January 2021

The paper presents an approach to design the adaptive output tracking controller for disturbed Twin Rotor Multi-Input Multi-Output System (TRMS) by using a time receding observer of functional disturbances for compensative control purpose, without using conventional methods as a neural network. To do this, first the disturbed Euler-Lagrange model of TRMS is converted to an equivalent bilinear form. And then, secondly an optimal disturbances estimator for this disturbed bilinear system is constructed based on time receding minimizing their effect. The complete output tracking controller for TRMS is created then by combining an exact linearization controller with the proposed disturbances estimation mechanism. Simulation results show that the here suggested controller meet completely the expected output tracking performances.
