Authors: Yoo Junsang , Lee Jeonghoon , Rhee Poong-Lyul , Chang Dong Kyung , Kang Mira , Choi Jong Soo , Bates David W , Cha Won Chul
Published: August 2020

BACKGROUND

Physicians’ alert overriding behavior is considered to be the most important factor leading to failure of computerized provider order entry (CPOE) combined with a clinical decision support system (CDSS) in achieving its potential adverse drug events prevention effect. Previous studies on this subject have focused on specific diseases or alert types for well-defined targets and particular settings. The emergency department is an optimal environment to examine physicians’ alert overriding behaviors from a broad perspective because patients have a wider range of severity, and many receive interdisciplinary care in this environment. However, less than one-tenth of related studies have targeted this physician behavior in an emergency department setting.

OBJECTIVE

The aim of this study was to describe alert override patterns with a commercial medication CDSS in an academic emergency department.

METHODS

This study was conducted at a tertiary urban academic hospital in the emergency department with an annual census of 80,000 visits. We analyzed data on the patients who visited the emergency department for 18 months and the medical staff who treated them, including the prescription and CPOE alert log. We also performed descriptive analysis and logistic regression for assessing the risk factors for alert overrides.

RESULTS

During the study period, 611 physicians cared for 71,546 patients with 101,186 visits. The emergency department physicians encountered 13.75 alerts during every 100 orders entered. Of the total 102,887 alerts, almost two-thirds (65,616, 63.77%) were overridden. Univariate and multivariate logistic regression analyses identified 21 statistically significant risk factors for emergency department physicians’ alert override behavior.

CONCLUSIONS

In this retrospective study, we described the alert override patterns with a medication CDSS in an academic emergency department. We found relatively low overrides and assessed their contributing factors, including physicians’ designation and specialty, patients’ severity and chief complaints, and alert and medication type.
Using Character-Level and Entity-Level Representations to Enhance Bidirectional Encoder Representation From Transformers-Based Clinical Semantic Textual Similarity Model: ClinicalSTS Modeling Study (Preprint)
Authors: Xiong Ying , Chen Shuai , Chen Qingcai , Yan Jun , Tang Buzhou
Published: August 2020

BACKGROUND

With the popularity of electronic health records (EHRs), the quality of health care has been improved. However, there are also some problems caused by EHRs, such as the growing use of copy-and-paste and templates, resulting in EHRs of low quality in content. In order to minimize data redundancy in different documents, Harvard Medical School and Mayo Clinic organized a national natural language processing (NLP) clinical challenge (n2c2) on clinical semantic textual similarity (ClinicalSTS) in 2019. The task of this challenge is to compute the semantic similarity among clinical text snippets.

OBJECTIVE

In this study, we aim to investigate novel methods to model ClinicalSTS and analyze the results.

METHODS

We propose a semantically enhanced text matching model for the 2019 n2c2/Open Health NLP (OHNLP) challenge on ClinicalSTS. The model includes 3 representation modules to encode clinical text snippet pairs at different levels: (1) character-level representation module based on convolutional neural network (CNN) to tackle the out-of-vocabulary problem in NLP; (2) sentence-level representation module that adopts a pretrained language model bidirectional encoder representation from transformers (BERT) to encode clinical text snippet pairs; and (3) entity-level representation module to model clinical entity information in clinical text snippets. In the case of entity-level representation, we compare 2 methods. One encodes entities by the entity-type label sequence corresponding to text snippet (called entity I), whereas the other encodes entities by their representation in MeSH, a knowledge graph in the medical domain (called entity II).

RESULTS

We conduct experiments on the ClinicalSTS corpus of the 2019 n2c2/OHNLP challenge for model performance evaluation. The model only using BERT for text snippet pair encoding achieved a Pearson correlation coefficient (PCC) of 0.848. When character-level representation and entity-level representation are individually added into our model, the PCC increased to 0.857 and 0.854 (entity I)/0.859 (entity II), respectively. When both character-level representation and entity-level representation are added into our model, the PCC further increased to 0.861 (entity I) and 0.868 (entity II).

CONCLUSIONS

Experimental results show that both character-level information and entity-level information can effectively enhance the BERT-based STS model.
Detecting Subclinical Social Anxiety Using Physiological Data from a Wrist-worn Wearable: A Small-Scale Feasibility Study (Preprint)
Authors: Shaukat Jali Ruksana , Van Zalk Nejra , Boyle David
Published: August 2020

BACKGROUND

Subclinical (i.e., threshold) social anxiety can greatly affect young people’s lives, but existing solutions appear inadequate considering its rising prevalence. Wearable sensors may provide a novel way to detect social anxiety and result in new opportunities for monitoring and treatment that would be greatly beneficial for sufferers, society and healthcare services. Nevertheless, indicators such as skin temperature from wrist-worn sensors have not been used in prior work on physiological social anxiety detection.

OBJECTIVE

This study aimed to investigate whether subclinical social anxiety in young adults can be detected using physiological data obtained from wearable sensors, including Heart Rate (HR), Skin Temperature (ST) and Electrodermal Activity (EDA).

METHODS

Young adults (N = 12) with self-reported subclinical social anxiety (measured by the widely used self-reported version of the Liebowitz Social Anxiety Scale, LSAS-SR) participated in an impromptu speech task. Physiological data was collected using an E4 Empatica wearable device. Using the pre-processed data and following a supervised machine learning approach, various classification algorithms such as Support Vector Machine (SVM), Decision Tree, Random Forest and K-Nearest Neighbours (KNN) were used to develop models for three different contexts. Models were trained to (1) classify between baseline and socially anxious states, (2) differentiate between baseline, anticipation anxiety and reactive anxiety states, and (3) classify between social anxiety experienced by individuals with differing social anxiety severity. The predictive capability of the singular modalities was also explored in each of the three supervised learning experiments. The generalisability of the developed models was evaluated using 10-fold cross validation as a performance index.

RESULTS

With modalities combined, the developed models yielded accuracies between 97.54% and 99.48% when detecting between baseline and socially anxious states. Models trained to differentiate between baseline, anticipation anxiety and reactive anxiety states yielded accuracies between 95.18% and 98.10%. Alongside this, the models developed to detect between social anxiety experienced by individuals with differing anxiety severity scores successfully classified with accuracies between 98.86% and 99.52%. Surprisingly, EDA was identified as the most effective singular modality when differentiating between baseline and social anxiety states, whereas ST was the most effective modality when differentiating between anxiety experienced by individuals with differing social anxiety severity.

CONCLUSIONS

The results indicate that it is possible to accurately detect social anxiety as well as distinguish between levels of severity in young adults by leveraging physiological data collected from wearable sensors.
KIAI INTERPERSONAL MANAGERIAL: HENRY MINTZBERG PERSPECTIVE
Authors: Karim Abdul , Afnan Dikhorir
Published: August 2020

The applicative theory used as a supporting statement is the concept of Henry Mintzberg's interpersonal managerial role. It is undeniable to see the gap between management theory and the concept of social interaction in Islam. The term defined by some experts is bounded value, individual, and nonexclusive. The theory emphasizes more on the system through management functions, whereas in Islam, the leadership figures are more desirable. This study answers, how is the application of interpersonal managerial roles in the Al-Ishlah Islamic Boarding School from Henry Mintzberg's perspective? The method used in this study is qualitative research with observation and interview instruments as tools of data collection. From the results of data collection, researchers conducted descriptive analysis steps namely categorization, reduction, and interpretation. The results show that Kiai's interpersonal managerial role forms as: first, Kiai al-Ishlah figure, and the ceremonial stage of the leadership. Second, the pattern of the al-Ishlah Islamic boarding school organization, personal improvement, independence, productivity, and special training. Third, educational cooperation and equality cooperation. The implication is that it is understandable that management theory is not the main theory used in an Islamic boarding school because the managerial role of Kiai managerial firmly determines the pace of Islamic boarding school management

UMA ANÁLISE SOBRE O WHATSAPP E SUAS RELAÇÕES COM A EDUCAÇÃO: dos aplicativos às tecnologias frugais
Authors: Bortolazzo Sandro Faccin
Published: August 2020

Este artigo desenvolve uma análise sobre o aplicativo de mensagens instantâneas WhatsApp e suas relações com a educação. O texto examina o WhatsApp enquanto uma tecnologia frugal, ou seja, de fácil uso e baixo custo. O estudo está organizado a partir de dois movimentos, sendo o primeiro uma apresentação do aplicativo, e o segundo desenvolve uma reflexão sobre as vantagens e desvantagens da utilização do WhatsApp na educação escolarizada. Para ambos intentos, acionam-se autores como Gere (2008), Tomilinson (2008), Whitesides (2012), entre outros, explorando aspectos sobre as tecnologias frugais, educação e cultura digital. Os achados da análise indicam um aplicativo que tem crescido em termos de popularidade. Entre as vantagens dos seus usos estão o reduzido custo, o entrecruzamento de linguagens e a mobilidade. Já entre as desvantagens pode-se considerar certa continuação da função de professor para além do expediente laboral, apontando indícios de um sistema tecnológico orientado a uma cultura do imediatismo.

Published: August 2020

ResumenLos murciélagos desempeñan un papel fundamental en los ecosistemas, ya que efectúan múltiples interacciones bióticas como la dispersión de semillas, polinización y el control de plagas, además de que poseen hábitos alimenticios muy variados. En Nayarit se han registrado 67 especies de quirópteros, pero ningún estudio se ha enfocado en las zonas urbanas del estado. Nuestro objetivo fue evaluar la diversidad y abundancia de murciélagos en las áreas verdes de la zona urbana de Tepic, Nayarit. Se realizó un muestro en nueve sitios empleando una red de 12 metros, colocada de 18:00 h a 23:00 h., durante el periodo de noviembre del 2015 a noviembre del 2016, en el cual se acumuló un total de 45 horas/red. Se muestrearon tres tipos de hábitat urbanos: plazas, zanjones y parques. Con los datos recabados se estimó el índice de diversidad alfa de Shannon y se realizó una prueba de t modificada por Hutchenson para comparar los distintos ecosistemas. Se registraron tres especies de murciélagos (Artibeus lituratus, Artibeus jamaicensis y Artibeus hirsutus). Los parques resultaron el ecosistema que registró la mayor diversidad y abundancia de murciélagos, mientras que la especie que se documentó con mayor frecuencia fue A. lituratus.Palabras clave: ambientes antropizados, parques urbanos, quirópteros.AbstractThe bats play a fundamental role in the ecological processes of ecosystems, they carry out multiple biotic interactions such as seed dispersers, pollination, and pest control, they also have very varied feeding habits.

This article aims to deal with the questionsof that does the concept of kufu’ influence marriage in the circle of Muslim-Arab creoles society? Why it happens and what are the relevant factors conditioning the phenomenon of marriage? Applying sociology of law in approaching the case, this article finds that although in the Arab-Muslim tradition kufu’ (equity) which means nasab(descent) considered can guarantee and strengthen a harmonic marriage relation, understanding on the nasab concept has shifted significantly. This article argues that nasab in the context of modern society has not become a primary reference in deciding marriage.

This article examines how the meaning of s{aduqa>tdannih}lahis seen from the semantic approach The term or word used by the Koran to indicate dowryis three: fari>d}ah, uju>r,, and s{aduqa>t. However, the word s{aduqa>t. which indicates the meaning of dowry in general without any designation of time must exclude it. In addition, it is also accompanied by the word nihlah which indicates the status and purpose or function of the bride price. So this word was chosen to be studied. The word will be approached by the semantic theory of Toshihiko Izutsu. There are two meanings that are explored namely the basic meaning and relational meaning.
Quantum Algorithms for Simulating the Lattice Schwinger Model
Authors: Shaw Alexander F. , Lougovski Pavel , Stryker Jesse R. , Wiebe Nathan
Published: August 2020

The Schwinger model (quantum electrodynamics in 1+1 dimensions) is a testbed for the study of quantum gauge field theories. We give scalable, explicit digital quantum algorithms to simulate the lattice Schwinger model in both NISQ and fault-tolerant settings. In particular, we perform a tight analysis of low-order Trotter formula simulations of the Schwinger model, using recently derived commutator bounds, and give upper bounds on the resources needed for simulations in both scenarios. In lattice units, we find a Schwinger model onN/2physical sites with coupling constantx−1/2and electric field cutoffx−1/2Λcan be simulated on a quantum computer for time2xTusing a number ofT-gates or CNOTs inO~(N3/2T3/2xΛ)for fixed operator error. This scaling with the truncationΛis better than that expected from algorithms such as qubitization or QDRIFT. Furthermore, we give scalable measurement schemes and algorithms to estimate observables which we cost in both the NISQ and fault-tolerant settings by assuming a simple target observable–the mean pair density. Finally, we bound the root-mean-square error in estimating this observable via simulation as a function of the diamond distance between the ideal and actual CNOT channels. This work provides a rigorous analysis of simulating the Schwinger model, while also providing benchmarks against which subsequent simulation algorithms can be tested.
‘Azl Sebagai Pencegah Kehamilan (Studi Perbandingan Antara Mazhab Hanafi dan Mazhab Syafi’i)
Authors: Djawas Mursyid , Misran Misran , Ujong Cut Putrau
Published: August 2020

‘Azl mungkin metode kontrasepsi tertua di dunia, karena ‘azl cara efektif untuk mencegah kehamilan.’azl berarti menarik penis dari vagina keluarnya sperma. Pastinya orang yang melakukan ‘azl (senggama terputus) ada maksudnya,seperti menunda kehamilan atau menjaga jarak dari anak sebelumnya. Karena Ketika sperma yang dikeluarkan di luar vagina pasti tidak akan terjadi pembuahan sehingga tidak terjadi kehamilan. Dalam konteks kekinian ‘azl mengalami pergeseran, ini dapat kita lihat dari pelaksanaan maksud dan tujuan program keluarga berencana (KB), yaitu mengatur jumlah kelahiran. Pengertian secara khusus KB adalah pencegahan konsepsi atau pencegahan pertemuan sel mani laki-laki dengan sel telur perempuan. Jika dilihat hasilnya nya antara ‘azl dan KB adalah sama, karena tujuannya sama-sama untuk mencegah pembuahan (kehamilan), tapi yang membedakan antara KB dan ‘azl hanya pada proses dan alat yang digunakan, ‘azl tidak mengggunakan alat apapun (secara alami) sendangkan KB mengunakan alat kontrasepsi baik berupa pil kb atau suntikan obat. Berdasarkan hasil istinbath hukum antara mazhab hanafi dan mazhab syafi`i, praktek ‘azl di bolehkan, meskipun berbeda pendapat dari segi pelaksanaanya. Mazhab hanafi membolehkan praktek ‘azl dilakukan oleh pasangan suami istri asal adanya persetujuan dari istri, sedangkan menurut pandangan mazhab syafi`i praktek ‘azl  malah dibebaskan tanpa harus adanya persetujuan dari istri.
Persepsi Masyarakat Tentang Pelaksanaan Iddah Wanita Karier Karena Cerai Mati Di Kec. Blangkejeren Kab. Gayo Lues
Authors: Devy Soraya , Maryam Maryam
Published: August 2020

Perkembangan dunia modern dewasa ini, banyak kaum wanita muslimah yang aktif di berbagai bidang, baik itu politik, sosial dan lainnya. Perempuan yang bekerja disebut sebagai wanita karier. Persepsi masyarakat bahwa seorang wanita karier yang tetap berkarier selama menjalani iddahnya karena cerai mati oleh suaminya dianggap menentang hukum islam. Karena menurut pemahaman masyarakat tersebut dalam masa iddah tidak boleh keluar rumah apalagi bekerja diluar rumah, memakai pakaian yang celup dengan warna kecuali hitam dan tidak dibolehkan bersolek. Permasalahan dalam penelitian ini adalah bagaimana persepsi masyarakat tentang pelaksanaan iddah wanita karier karena cerai mati di Kecamatan Blangkejeren Kabupaten Gayo Lues dan bagaimana tinjauan hukum Islam terhadap persepsi masyarakat tentang pelaksanaan iddah wanita karier karena cerai mati di Kecamatan Blangkejeren Kabupaten Gayo Lues. Untuk mencapai tujuan tersebut, peneliti menggunakan pendekatan kualitatif. Metode penelitian yang dipakai untuk meneliti ini adalah studi kepustakaan dan studi lapangan dengan metode wawancara, angket dan dokumentasi. Hasil yang didapati adalah 98% responden mengetahui bahwa apabila wanita karier yang ditinggal mati oleh suaminya maka wanita tersebut harus beriddah serta masyarakat juga memahami bagi wanita karier yang ditinggal mati oleh suaminya tersebut maka wanita tersebut harus berhenti bekerja selama menjalankan masa tunggunya yakni selama 4 bulan 10 hari, 100% responden menyetujui bahwa wanita karier yang sedang menjalankan iddahnya tersebut dilarang keluar rumah, bersolek, memakai pakaian yang celup dengan warna kecuali hitam dan dilarang menikah. 100% responden menyetujui bahwa persepsi tersebut muncul dari kebiasaan masyarakat setempat. Menurut tinjauan hukum Islam wanita karier yang di cerai mati oleh suaminya tersebut boleh bekerja tetapi memiliki batasan-batasan terhadapnya. Misalnya perempuan tersebut boleh berhias yakni hanya untuk memenuhi syarat dari pekerjaannya, dengan tujuan agar wanita karier tersebut tidak di pecat dari pekerjaanya.

Published: August 2020

This research departs from the fact that learning with nuances of guidance in extraordinary elementary schools has not been done much so that the purpose of this study is to find out data about these matters. This study uses a quantitative approach with descriptive methods with 34 teachers as respondents. Areas that become indicators are mastery of identification and assessment of students, the ability of teaching theories & principles of educational learning, and the development of learning tools with instructional learning principles. The results showed that in the mastery of identification and assessment, most of the students were in the less competent category, a few were competent, and the rest were less skilled. The ability to master learning theory and educational learning principles shows that most of them are in the competent category and the rest are in the weak and incompetent category, while the ability to develop learning tools following nuanced learning guidance is mostly in the category of resting competent very competent, incompetent and less competent. Based on the data obtained in the research results, it shows that the competence of elementary school class teachers is extraordinary in carrying out guided learning and shows excellent competence so that it still requires development assistance using various techniques, methods, strategies, and appropriate approaches.
TESSITURAS LABIRÍNTINCAS: A MISE EN ABYME E A METALEPSE COMO RAMIFICAÇÕES DA NARRATIVA, EM “BANDERSNATCH’, EPISÓDIO DA SÉRIE BLACK MIRROR
Authors: Da Costa Alexandre Rodrigues
Published: August 2020

Neste artigo, analisamos o episódio “Bandersnatch”, da série de TV Black Mirror, criada por Charlie Brooker e produzida pelo canal de streaming Netflix, a partir dos conceitos de mise en abyme e metalepse, como possibilidade de criação de narrativas ramificadas e labirínticas. Dessa maneira, investigamos de que forma a permutação permite a “Bandersnatch” interagir com o telespectador e, baseando-nos na fragmentação que decorre desse processo, relacionamos a mise en abyme e a metalepse ao conceito de imagem-tempo, de Gilles Deleuze, e aos conceitos de Cronos e Aion, que ele explora a partir dos textos estoicos. Além disso, estabelecemos comparações entre “Bandersnatch” e os filmes A origem, de Christopher Nolan, Os olhos da cidade são meus, de Bigas Luna, e Eu te amo, eu te amo, de Alain Resnais, com o objetivo de perceber como a mise en abyme e a metalepse dilaceram a progressão e a linearidade, ao fazerem com que a repetição e a circularidade colapsem a narrativa e a ofereçam como um jogo de realidades instáveis.

Memória cultural e o espaço (re)imaginado em Hóspedes da Noite, de Licínio Azevedo
Authors: Vieira Tiago , Macedo Isabel
Published: August 2020

O cinema desempenha um papel ativo na formação da nossa compreensão do passado e na definição da agenda para futuros atos de lembrança no seio da sociedade, dado que constitui um meio de memória cultural e visual sobre os países e os espaços e períodos representados. O Grande Hotel da Beira, símbolo de luxo no período colonial, é-nos apresentado em Hóspedes da noite, por dois ex-funcionários, que relembram a sua grandiosidade, enquanto, em simultâneo ouvimos os testemunhos dos novos donos que ocupam este espaço, e que reacendem a memória das deslocações forçadas e dos impactos da Guerra Civil em Moçambique. As memórias do período colonial, mesmo não sendo evocadas (não há qualquer referência ao período colonial), assomam na imagem como a emanação fantasmagórica que inscreve o então presente e eiva o futuro, fazendo com que a preocupação central personagens seja a sobrevivência.

Medición de materiales con radiación Terahertz
Authors: Escobar Mejía Andrés Felipe
Published: August 2020

La radiación Terahertz (THz) o Rayos T, define las ondas electromagnéticas con un rango de frecuencias entre 0,1 THz y 10 THz. Es posible categorizar las técnicas de detección de radiación en la banda de los THz en técnicas coherentes e incoherentes. La principal diferencia entre ellas es que en la técnica coherente se determinan tanto la amplitud como la fase de la señal recibida; pero, en la técnica incoherente, solo se mide la intensidad de la señal.La espectroscopía THz en el dominio del tiempo es, generalmente un método coherente. Los detectores directos como los piroeléctricos son principalmente detectores incoherentes.  Este artículo presenta la medición experimental de diferentes materiales cuando se irradian con radiación de terahertz, aplicando técnicas de espectroscopia THz en el dominio del tiempo. La radiación es emitida por una antena fotoconductora, excitada por un láser de femtosegundos. Los resultados se obtienen al medir el pulso THz transmitido a través de los materiales al implementar sistemas de detección coherentes e incoherentes, al analizar los datos obtenidos, se logró obtener el índice de refracción y coeficiente de absorción, en caso de la técnica coherente, y el coeficiente de absorción en la técnica incoherente, para los distintos materiales estudiados en este trabajo.

El propósito investigativo que inspira este artículo es comparar el impacto de tres estrategias motivadoras en evaluaciones escritas frente al método de la evaluación tradicional en Programación de Computadores. Se acudió a un estudio durante seis semestres con grupos de una misma asignatura. Cada grupo se dividió en dos subgrupos; con uno de ellos se aplicó la metodología presentada y con el otro se aplicó la forma tradicional de evaluación escrita, todo ello apoyado en características fisiológicas del cerebro, la manera como aprende el cerebro y la estrategia Brain Based Learning. Los resultados evidencian que cuando el cerebro se encuentra en momentos de tensión, una acción bien conducida permite que elementos clave de aprendizaje se ubiquen en la memoria a largo plazo. Se concluye que, si se tienen claros los objetivos de una evaluación y su diseño es apropiado, conviene aplicar estas estrategias en las evaluaciones escritas tanto en programación de computadores como en otras áreas disciplinares. Se ha adoptó un enfoque cuantitativo asociado a un estudio de caso grupal.

El compensador estático de potencia para distribución (D-STATCOM, Distribution Static Power Compensator) es un dispositivo para la compensación de potencia reactiva en redes eléctricas de distribución que tiene ventajas sobre los capacitores convencionales debido a que evita resonancias de potencia y pueden} realizar una compensación continua, alcanzando factores de potencia cercanos a la unidad. Este artículo describe la implementación de un D-STATCOM para compensación reactiva en redes de distribución, haciendo una rigurosa explicación de cada uno de sus componentes. Se desarrolló un inversor trifásico de seis pulsos con dos niveles. Se describe completamente la implementación del hardware de las diferentes etapas (sensores, conmutación de potencia, elementos pasivos y procesador). El firmware que permite la operación del D-STATCOM se implementó en un DSP TMS3202F (Texas Instruments) con un enfoque modular. La correcta operación del prototipo de D-STATCOM se validó con resultados experimentales. Resultados mostraron una apropiada corrección del factor de potencia, reducción de la corriente demandada por la red eléctrica y un correcto funcionamiento del sistema de control, algoritmos y hardware.

Published: August 2020

Este artículo presenta el diseño de una estrategia inteligente, para el diagnóstico automático de procesos industriales mediante la predicción con Redes Neuronales Artificiales (RNAs) y clasificación difusa. Para diseñar la estrategia de diagnóstico se utilizó información histórica del proceso. La clasificación fue implementada como herramienta para el agrupamiento difuso de patrones. Las RNAs de configuración multicapa fueron entrenadas para predecir los estados funcionales del proceso. Las salidas en la etapa de predicción son las entradas del clasificador. En el esquema de diagnóstico propuesto la estimación de los estados funcionales es presentada a los operarios de los procesos, como información futura para generar las acciones preventivas antes de la transición hacia un estado de falla. La estrategia propuesta fue implementada sobre un sistema de control convencional; y sobre un sistema de producción de aire medicinal.

Los sistemas solares de paneles orientables mejoran grandemente su desempeño, basado no solamente en el movimiento en el momento indicado, sino también una adecuada estrategia de movimiento para describir esa rotación.  El control de un Sistema de Panel Solar Orientable de dos grados de libertad fue simulado para un esquema de control que combina acciones Proporcional, Integral y Derivativa con un lazo interno de control de par computado. Este lazo interno de control permite el cálculo de torques en las juntas.  Fueron evaluadas dos plantas del modelo dinámico del Panel Solar Orientable: analítica y Simmechanics. Tres casos de movimiento fueron simulados: aleatorio, a una posición segura y final del ciclo diario. Las ganancias del controlador se hallaron usando la oscilación sostenida del segundo método de sincronización Nichols-Ziegler. Para ahorrar energía durante el movimiento, se requiere movimiento no subamortiguado, obtenido mediante la anulación de la componente integral del controlador. Errores de posición teóricos muy pequeños para ángulos de elevación y azimut, sugieren que el esquema Proporcional Dreivativo con Control de Torque Calculado es satisfactorio para controlar el movimiento del panel durante el día.

Los aceites de origen vegetal fueron una de las principales fuentes de aceites lubricantes antes de la aparición del petróleo. Actualmente, debido a la baja estabilidad térmica y a la oxidación, no se emplean con la misma frecuencia en el sector industrial. Sin embargo, los diferentes ácidos grasos que componen los aceites vegetales pueden reducir significativamente el coeficiente de fricción. Para optimizar la lubricación, el aceite vegetal puede ser mezclado con aditivos. En esta investigación, se realizó un estudio comparativo del poder lubricante del aceite de Ajonjolí con Cera polietilénica y Parafina como aditivos. Esta propiedad, fue evaluada mediante ensayos de desgaste preventivo y presión extrema en un tribómetro cuatro bolas. Los resultados experimentales, mostraron que para la prueba de desgaste preventivo D.P la mezcla con cera polietilénica, presenta el menor diámetro promedio de huella, mientras para la prueba de extrema presión E.P la mezcla con parafina dio una mayor resistencia a la carga aplicada, obteniendo un punto de soldadura a 32 Kg-F (314N) siendo mayor que para el aceite y con cera polietilénica (24 Kg-F (235N)). En relación al coeficiente de fricción los resultados obtenidos muestran que no existe diferencia entre el aceite y las mezclas con los diferentes aditivos. A partir de estos resultados, se puede concluir que el rendimiento del aceite de ajonjolí como lubricante, se puede mejorar mediante su mezcla con parafina y cera polietilénica, sin embargo, los porcentajes añadidos deben determinarse correctamente.

Reduced activation of energy metabolism increases adiposity in humans and other mammals. Thus, exploring dietary and molecular mechanisms able to improve energy metabolism is of paramount medical importance because such mechanisms can be leveraged as a therapy for obesity and related disorders. Here, we show that a designer protein-deprived diet enriched in free essential amino acids can 1) promote the brown fat thermogenic program and fatty acid oxidation, 2) stimulate uncoupling protein 1 (UCP1)-independent respiration in subcutaneous white fat, 3) change the gut microbiota composition, and 4) prevent and reverse obesity and dysregulated glucose homeostasis in multiple mouse models, prolonging the healthy life span. These effects are independent of unbalanced amino acid ratio, energy consumption, and intestinal calorie absorption. A brown fat-specific activation of the mechanistic target of rapamycin complex 1 seems involved in the diet-induced beneficial effects, as also strengthened by in vitro experiments. Hence, our results suggest that brown and white fat may be targets of specific amino acids to control UCP1-dependent and -independent thermogenesis, thereby contributing to the improvement of metabolic health.

Reduced activation of energy metabolism increases adiposity in
humans and other mammals. Thus, exploring dietary and molecular mechanisms able
to improve energy metabolism is of paramount medical importance, as such
mechanisms can be leveraged as a therapy for obesity and related disorders.
Here, we show that a designer protein-deprived diet
enriched in free essential amino acids can i) promote the brown fat
thermogenic program and fatty acid oxidation, ii) stimulate uncoupling
protein 1 (UCP1)-independent respiration in subcutaneous white fat, iii) change
the gut microbiota composition, and iv) prevent and reverse obesity and
dysregulated glucose homeostasis in multiple mouse models, prolonging the healthy
lifespan. These effects are independent of unbalanced amino acid ratio,
energy consumption, and intestinal calorie absorption. A brown fat-specific
activation of the mechanistic target of rapamycin complex 1 seems involved in the
diet-induced beneficial effects, as also strengthened by in vitro experiments. Hence, our results suggest that brown and
white fat may be targets of specific amino acids to control UCP1-dependent
and -independent thermogenesis, thereby contributing
