Enhancing the Kramers–Kronig receiver via dispersion-based spatial diversity
Authors: Blech Lior , Antonelli Cristian , Mecozzi Antonio , Eldar Yonina C. , Shtaif Mark
Published: May 2020

We report a scheme for reconstructing the complex envelope of an optical signal from two decorrelated measurements of its intensity. The decorrelation is achieved by splitting the received optical signal into two copies, and by dispersing one of the copies prior to photo detection. The reconstructed complex-valued signal is obtained by means of an iterative algorithm that requires only a few tens of iterations. The starting point of the search procedure is produced by Kramers–Kronig (KK) reconstruction. With this procedure, the continuous-wave tone that accompanies the received signal is reduced by 5 dB to 6 dB compared to the requirement of a KK receiver alone.

We experimentally demonstrate the utilization of adaptive optics (AO) to mitigate intra-group power coupling among linearly polarized (LP) modes in a graded-index few-mode fiber (GI FMF). Generally, in this fiber, the coupling between degenerate modes inside a modal group tends to be stronger than between modes belonging to different groups. In our approach, the coupling inside the

L
P

11

group can be represented by a combination of orbital-angular-momentum (OAM) modes, such that reducing power coupling in OAM set tends to indicate the capability to reduce the coupling inside the

GI FMF. The power coupling is mitigated by shaping the amplitude and phase of the distorted OAM modes. Each OAM mode carries an independent 20-, 40-, or 100-Gbit/s quadrature-phase-shift-keying data stream. We measure the transmission matrix (TM) in the OAM basis within

group, which is a subset of the full LP TM of the FMF-based system. An inverse TM is subsequently implemented before the receiver by a spatial light modulator to mitigate the intra-modal-group power coupling. With AO mitigation, the experimental results for

An Experimental Performance Comparison of Widely Used Face Detection Tools
Authors: Kabakus Abdullah Talha
Published: May 2020

Face detection is the task of detecting faces on photos, videos as well as the streaming data such as a webcam. Face detection, which is a specific type of general-purpose object detection, is a key prerequisite for many other artificial intelligence tasks such as face verification, face tagging and retrieval, and face tracking. In addition to that, nowadays, face detection is commonly used in daily routines such as social media, and camera software of smartphones. As a result of this necessity, several face detection tools have been proposed. In this study, an experimental performance comparison of well-known face detection tools in terms of (1) accuracy, and (2) elapsed time of detection, which has become even more critical criteria especially when the face detection mechanism is utilized for a real-time system, is proposed. As a result of this experimental study, it is aimed that shed light on the much-concerned query “which face detection tool provides the best performance?”. In addition to that, this study succeeds in showing that convolutional neural networks achieve great accuracy for face detection.
ck-NN: A Clustered k-Nearest Neighbours Approach for Large-Scale Classification
Authors: Ullah Rafi , Khan Ayaz H. , Emaduddin S.M.
Published: May 2020

k-Nearest Neighbor (k-NN) is a non-parametric algorithm widely used for the estimation and classification of data points especially when the dataset is distributed in several classes. It is considered to be a lazy machine learning algorithm as most of the computations are done during the testing phase instead of performing this task during the training of data. Hence it is practically inefficient, infeasible and inapplicable while processing huge datasets i.e. Big Data. On the other hand, clustering techniques (unsupervised learning) greatly affect results if you do normalization or standardization techniques, difficult to determine "k" Value. In this paper, some novel techniques are proposed to be used as pre-state mechanism of state-of-the-art k-NN Classification Algorithm. Our proposed mechanism uses unsupervised clustering algorithm on large dataset before applying k-NN algorithm on different clusters that might running on single machine, multiple machines or different nodes of a cluster in distributed environment. Initially dataset, possibly having multi dimensions, is pass through clustering technique (K-Means) at master node or controller to find the number of clusters equal to the number of nodes in distributed systems or number of cores in system, and then each cluster will be assigned to exactly one node or one core and then applies k-NN locally, each core or node in clusters sends their best result and the selector choose best and nearest possible class from all options. We will be using one of the gold standard distributed framework. We believe that our proposed mechanism could be applied on big data. We also believe that the architecture can also be implemented on multi GPUs or FPGA to take flavor of k-NN on large or huge datasets where traditional k-NN is very slow.
El concepto de infancia en la Baja Edad Media en Castilla a través de los «Espejos de Príncipes» (siglos XIII-XV)
Authors: Asenjo Travesí Enrique
Published: May 2020

Durante la Baja Edad Media, Castilla vive un resurgir de la literatura sapiencial en lo tocante a la formación moral e intelectual de los príncipes. Es este un fenómeno novedoso al calor del resurgir de la cultura clásica y la revisión de los textos latinos bajo una nueva dimensión en esta época. Los reinos bajomedievales hispanos adoptaron una nueva visión de los textos clásicos no solo desde el punto de vista moralizante cristiano, sino desde una óptica laica y más práctica. La literatura sapiencial o los «Espejos de Príncipes» constituyen un ejemplo del afán por formar al buen príncipe o monarca ante un contexto político cambiante y novedoso, pero también, como un recurso habitual en la Edad Media, se hace mirando al pasado clásico como referente inicial.
Los manuales pioneros en la construcción de la Didáctica General en España
Authors: Heredia Manrique Alfonso
Published: May 2020

Este trabajo se enmarca dentro de la historia de las disciplinas pedagógicas, en este caso se refiere a los antecedentes de la Didáctica General en España, en cuyo origen encontramos un conjunto de manuales que llevan por título el de Didáctica Pedagógica y publicados en las dos primeras décadas del siglo XX. Así se realiza un análisis de estos manuales en cuanto a su organización interna y al valor que presentan los contenidos de cada parte, que vienen a ser de Metodología General, Metodología Especial y Organización Escolar. Los resultados de la comparación realizada nos llevan a la conclusión de que la Didáctica Pedagógica encarna la búsqueda de una mayor autonomía de la parte metodológica o didáctica dentro de la Pedagogía; y donde la Metodología General, que tiene un escaso desarrollo, será el germen de la Didáctica General, centrando sus contenidos básicos en torno al método, los procedimientos y las formas de enseñanza.
Los cómics en la construcción de la propuesta educativa en el primer franquismo
Authors: Sanchidrián Fernández José Carlos
Published: May 2020

En los años posteriores a la finalización de la Guerra Civil 1936-1939, España tuvo que asumir las consecuencias dramáticas producidas por la insurrección. Debió enfrentarse no solo a la crisis de identidad de las dos Españas, sino al mantenimiento de un orden basado en el autoritarismo de corte fascista. La educación de niños y jóvenes constituyó uno de los esenciales argumentos en los que se apoyó el Gobierno de la nación para desplegar toda una política de adoctrinamiento compresivo y homogenizante que asegurase la llamada «paz social». Los cómics que aparecieron en esos años fueron uno de los instrumentos para la educación no formal de la población escolar.
A escola primária teuto-brasileira rural: educação e sincretismo em Santa Catarina
Authors: Santos Ademir Valdir dos
Published: May 2020

Objetiva analisar a origem da escola primária teuto-brasileira rural em Santa Catarina e sua instituição nas primeiras décadas do século xx. A metodologia é embasada na pesquisa documental, usando relatório, estatutos, termos de inspeção, estatísticas, livro, cadernos e fotografias. As análises são pautadas por bibliografia que aborda relações entre a educação e a imigração teuta. O exame das transformações por que passaram as escolas fundadas pelos imigrantes alemães em Santa Catarina mostra que, inicialmente, elas foram constituídas como escolas alemãs. Mas devido às modificações econômicas, políticas e socioculturais das primeiras décadas do século xx, construíram uma nova identidade, que amalgamou à germanidade elementos tipicamente brasileiros. Os resultados mostram que a escola primária teuto-brasileira rural é expressão de sincretismo, sendo originada do amálgama entre os dados germânicos trazidos com a imigração e as componentes culturais brasileiras.

Instruyendo sobre la recreación: Alcocer y la moderación en el XVI, clave en la educación para el juego
Authors: López De Prado Ortiz-Arce Ignacio
Published: May 2020

En el año 1559 Francisco de Alcocer, fraile franciscano, escribe un tratado sobre el juego. La intención del fraile no es otra que instruir y poner orden en un asunto que tanto daño ocasionaba en la sociedad del XVI. Los juegos en general, pero especialmente los de azar, debido a su gran difusión y lo desmesurado de las apuestas, traerán consigo la existencia de diversas leyes, tanto canónicas como civiles. Todas estas leyes se prestarán a una gran confusión en cuanto a la interpretación de las mismas. Los razonamientos de los diferentes juristas sostienen posturas contrapuestas, desde que el juego es siempre lícito, a que no se podrá realizar sin pecado mortal. La moderación será la piedra angular que dictará la permisibilidad de la práctica lúdica.

Sperm protein markers for Holstein bull fertility at National Artificial Insemination Centers in Indonesia
Authors: Rosyada Zulfi Nur Amrina , Ulum Mokhamad Fakhrul , Tumbelaka Ligaya I. T. A. , Purwantara Bambang
Published: May 2020

Background and Aim: Holstein cows and heifers are widely bred in Indonesia by artificial insemination (AI) to increase population and milk production. Sperm fertility is modulated by genetic factors, but the analysis of sperm quality is still based on macro- and microscopic characteristics. This study aimed to analyze both sperm quality and proteins of Holstein bulls at different fertility levels. Materials and Methods: The frozen semen samples were collected from the Indonesia National AI Center. They were classified based on the reproductive efficiency data and were grouped into high fertile (HF) and low fertile (LF). Sperm qualities were evaluated by microscopic evaluation. The Holstein sperm proteins were extracted using phenylmethanesulfonyl fluoride as a protease inhibitor and the benzidine detergent extraction method. Discontinuous sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) was conducted to analyze the molecular weights (MWs) of the sperm proteins. The data obtained were analyzed by a t-test using the one-factor bull fertility level, and Spearman's correlation analysis was used to identify the correlation between the sperm microscopic evaluation parameters and protein bands. Results: The sperm motility post-freeze thawing was not significantly different between the HF and LF (p>0.05). The HF level had a higher percentage of viability, intact plasma membrane integrity, and intact acrosomes than the LF (p<0.05). Five protein bands were found in the SDS-PAGE of sperm proteins of Holstein bulls with different concentrations. Sperm proteins with MWs of 17.51 kDa, 14.87 kDa, 33.71 kDa, and 41.97 kDa were abundant in the Holstein bulls with an HF level, while 55 kDa proteins were abundant in the LF level of Holstein bulls. The sperm of Holstein bulls in the HF level contained proteins of about 33.71 kDa that were not detected in the LF. Conclusion: The sperm protein with a molecular weight of 33.71 kDa was predicted to be a specific protein biomarker that influences bull fertility. Sperm fertilization abilities were also determined by the sperm proteins, the morphology of sperm acrosomes, and the quality of plasma membranes. This method can be used to select bulls with high fertility to increase the population of Holstein bulls.
Comparison of canine stifle kinematic analysis after two types of total knee arthroplasty: A cadaveric study
Authors: Thitiyanaporn Chaiyakorn , Chantarapanich Nattapon , Sompaisarnsilp Somchai , Thengchaisri Naris
Published: May 2020

Background and Aim: Osteoarthritis is a common consequence of cranial cruciate ligament rupture (CCLR) in the canine stifle. Total knee replacement is a valuable method for managing end-stage osteoarthritis. Materials and Methods: Two new designs of total knee replacement implants were fabricated with information from computed tomography scans. Canine hind limbs of cadavers were tested with a biomechanical testing machine with C-arm fluoroscopy. The four groups tested were as follows: Intact stifles (INTACT), CCLR, total knee arthroplasty (TKA) with a peg on top of the tibial component (TKAP), and TKA with no peg on top of the tibial component (TKAN). Extension, flexion, adduction, abduction, internal rotation, external rotation, cranial translation, caudal translation, and range of motion were measured. Results: The cranial translation of the tibia relative to the femur increased significantly after cutting off the cranial cruciate ligament. After arthroplasty, adduction/abduction and cranial/caudal translation within the TKAN group was increased compared with the intact stifle group. In the TKAP group, only adduction was greater than it was in the intact stifle group. Conclusion: The design of the prosthesis used for the TKAP group was more appropriate for total knee replacement in dogs than the design of the prosthesis for the TKAN group.

Clinical Decompensation and Outcomes in Patients With Compensated Cirrhosis and a Hepatic Venous Pressure Gradient ≥20 mm Hg
Authors: Jindal Ankur , Bhardwaj Ankit , Kumar Guresh , Sarin Shiv Kumar
Published: May 2020

INTRODUCTION:

Hepatic venous pressure gradient (HVPG) of ≥10 mm Hg predicts clinical decompensation (CD) in compensated cirrhosis. A proportion of cirrhotic patients at presentation have high HVPG (≥20 mm Hg) and are compensated. The natural history, spectrum of CD, and mortality in this group is largely unknown.

METHODS:

Consecutive compensated cirrhotic patients with HVPG ≥6 mm Hg (n = 741) were followed up for 3–6 months for the development of any CD. Patients were classified based on the baseline HVPG (6 to <12 mm Hg [low HVPG, Gr.A, n = 163], 12 to <20 mm Hg [intermediate HVPG, Gr.B, n = 437] and ≥20 mm Hg [high HVPG, Gr.C, n = 141]). We analyzed the predictors of first CD, HVPG response to carvedilol, and mortality in these groups.

RESULTS:

CD developed in 217 (29.3%) patients during a mean follow-up of 1.6 ± 0.4 years, and those who developed CD had higher baseline HVPG (17.02 ± 4.79 vs 14.28 ± 4.86; P < 0.001). First CD was seen earlier (1.3 ± 0.7 years vs 1.5 ± 0.6 years and 1.6 ± 0.5 years, P = 0.02) and more frequently (44.7% vs 11% and 31.1%, P < 0.01) in high HVPG groups compared with low and intermediate HVPG groups, with higher mortality rates. Patients in the high HVPG group compared with the low HVPG group more often had NASH-cirrhosis (35.5% vs 19.6%; P 0.001), higher liver stiffness values (45.06 ± 20.46 vs 20.09 ± 5.47 kPa, P < 0.001), and lower platelet counts (113.37 ± 72.57 vs 151.7 ± 87.30/cmm, P < 0.001). Patients with HVPG ≥12 mm Hg received carvedilol, and a repeat HVPG performed in a proportion after 9.3 ± 2.4 months showed response (≥20% reduction in HVPG or <12 mm Hg) in 31.6% patients (Gr. B, 44.9% > Gr. C, 22.2%, P < 0.05). Baseline HVPG (HVPG ≥12 to <20 mm Hg [Hazard ratio: 2.73] and HVPG ≥20 mm Hg [Hazard ratio: 4.48], P < 0.001) independently predicted CD.

DISCUSSION:

HVPG ≥20 mm Hg in patients with compensated cirrhosis independently predicts early and more frequent CD and poor outcomes. These patients should be labeled as “high-risk compensated cirrhosis,” and early and effective interventions to reduce portal pressure should be initiated to improve long-term outcomes.

Published: May 2020

INTRODUCTION:

We assessed whether celiac disease-associated mortality is increased in Finland among patients diagnosed in the 21st century, given recent improvements in diagnostic and treatment facilities.

METHODS:

Biopsy-proven patients with celiac disease (Marsh III) and dermatitis herpetiformis aged 20–79 years (median 50 years) diagnosed 2005–2014 (n = 12,803) were identified from the national dietary grant registry. Dates and causes of death were obtained from Statistics Finland. Overall mortality and causes of death were compared with reference individuals (n = 38,384) matched for age, sex, and area of residence (at the time of celiac disease diagnosis) selected from the Population Information System.

RESULTS:

During a mean follow-up of 7.7 years (SD ±3.0 years), 884 (6.9%) and 2,613 (6.8%) deaths occurred among the celiac cohort and reference group, respectively. Overall mortality (hazard ratio [HR] 1.01, 95% confidence intervals [CIs] 0.94–1.09), mortality from all malignancies (HR 1.11, 95% CI 0.96–1.27), gastrointestinal tract malignancies (HR 1.21, 95% CI 0.56–1.71), or cardiovascular diseases (HR 0.91, 95% CI 0.77–1.07) were not increased among patients with celiac disease. Overall, mortality from lymphoproliferative diseases (HR 2.36, 95% CI 1.65–3.39) and nonmalignant digestive diseases (HR 2.19, 95% CI 1.40–3.43) was increased, but HRs decreased after the exclusion of the first 2 years of follow-up (HR 1.71, 95% CI 1.10–2.66 and HR 1.75, 95% CI 1.01–3.05, respectively).

DISCUSSION:

The overall mortality in adult celiac disease diagnosed 2005–2014 was not increased. Mortality from lymphoproliferative diseases was increased but lower than previously reported.
“The Humble Petition of Johana Nyewuame Bekrah”: Becoming/Being Gã, Straddling “Spaces”, and Negotiating Boundaries in the Gold Coast Christian “Model Town” (Abokobi), ca. 1860–1980
Authors: Sewordor Ernest Sasu Kwame
Published: May 2020

By the mid-nineteenth century, Basel Mission (BM) evangelical activities on the Gold Coast had expanded beyond the Accra littoral and this significantly informed the establishment of many Pietist Christian urban enclaves or Salems for African converts. Salems therefore became sites that epitomized Basel missionary encounters on the Gold Coast. Abokobi, as an envisioned “Model Town,” is key because it was the only Salem established completely outside the sociopolitical ambit of an existing Accra polity. Abokobi is thus uniquely positioned for examining how intercultural exchanges shaped contested memories and for revealing the ways that African women of slave ancestry renegotiated identity and belonging. The assumption that the Christian outlook of Salems was enough to blur ethnic, hierarchical, and gendered differences is questioned in this study because such a notion misleads and shifts scholarly enquiry away from understanding the nuances of the everyday experiences of families of servile ancestry in Abokobi and other BM religious centers.
A Comprehensive Study of Weighted Product Model for Selecting the Best Product in Our Daily Life
Authors: Goswami Shankha Shubhra , Behera Dhiren Kumar , Mitra Dr Soupayan
Published: May 2020

Goal: the main objective of this research paper is to select the best laptop model among 6 models actually available in the market by applying multiple criteria decision making methodology (MCDM) on the basis of a physical market survey and opinions of 100 people specially consists of students. Since, choosing an appropriate laptop model among thousands of different available models is quite a challenging task for the students.

Design / Methodology / Approach: for this present analysis, a combined approach of analytic hierarchy process (AHP) and weighted product model (WPM) is developed. Where, AHP is used to calculate the criteria weightages and WPM is used to choose the best option and to rank the alternatives. The selection process is done based on the following seven important criteria of the laptop i.e. processor, hard disk capacity, operating system, RAM, screen size, brand, color.

Results: The final outcome result shows that Model 5 is the best choice among these 6 models followed by Model 3 and Model 2 whereas model 4 is the worst one among them. The specifications of the best laptop model 5 among this group are having I5 processor, 1TB hard disk capacity, windows operating system, 8GB RAM, 15.6-inch display, HP brand and color silver.

Limitations of the investigation: Since the weightages calculation and the final ranking mainly depends on the structure of the pair-wise comparison matrix (shown in Table 5) and the decision matrix (shown in Table 8), so the final results may vary based on the opinion of the other decision maker. Moreover, if the same problem is solved by applying other MCDM tools, the final output results may or may not be same.

Practical implications: From this present research work, students who are willing to buy a laptop can get a general guideline about the best laptop model and their specifications in the present market. Moreover, the laptop manufacturing companies can also get some ideas about the present market scenario since this analysis is based on the actual market survey which can help to frame their future strategies.

Originality / Value: Although, many literatures have been recorded related to the applications of MCDM tools in solving different decision making problems in different areas but very limited research work have been done in solving our daily life decision problems by applying MCDM.
Moderate Range Static Magnetic Field Promoted Variation of Blood Parameters: An In vitro Study
Authors: Mustafa Bestoon T. , Yaba Sardar P. , Ismail Asaad H.
Published: May 2020

This study was undertaken to investigate the influence of a homogenous and uniform static magnetic field (SMF) on the main blood cell counts in vitro experiment. Fresh blood samples were collected from albino rats and exposed to SMF (2.4, 6, 25, 50, 75, and 100 mT) versus 15–60 min. Results showed a significant change of blood counts under the low field effects. A 2.4 mT was a trend of white blood cells (WBCs) count increase non-linearly. However, a 6 mT exposure reduced WBCs with about 39%. Other variations fluctuated within 30%. The 25 mT decreased red blood cells (RBCs), hemoglobin, and hematocrit levels with 13% similarly. The lower exposure field, (2.4 and 6) mT, and effects on RBCs were 6% fluctuation. The 6 mT reduced platelet counts with half in comparison to control blood samples. About 20% increase obtained due to 50 mT exposure during all period. None of 75 and 100 mT exposures dominated blood counts alterations. The quiet magnetic field exposure for a certain time can be interesting to control blood cell count-related diseases.
Representing future generations in the deliberative valuation of ecosystem services
Authors: Mavrommati Georgia , Rogers Shannon , Howarth Richard B. , Borsuk Mark E.
Published: May 2020

Even though decisions taken today about managing ecosystem services are likely to have an effect on future generations’ well-being, decision making is based largely on current generations’ values, including altruistic concern for posterity. Deliberative forms of citizen engagement can provide a methodological framework for incorporating sustainability considerations in the valuation task and for understanding the reasoning behind peoples’ choices. This paper uses a deliberative form of citizen engagement to better understand the temporal dimensions of social values by incorporating into the valuation task two plausible future scenarios and assigning to the participants the role of trustees for future generations. In particular, we employed the deliberative multicriteria evaluation (DMCE) method with eleven groups in which a total of 67 participants assessed the relative importance of ten ecosystem services in the Upper Merrimack River watershed in New Hampshire. Our results suggest that a deliberative form of citizen engagement provides the appropriate space for incorporating intergenerational concerns into decision making. Participants set environmental targets by prioritizing the satisfaction of basic human needs, securing human and environmental health, and avoiding the loss of ecosystem services that cannot be substituted and may lead to irreversible future losses. This finding suggests that when preferences are socially constructed, then ethical values underpin valuations, making it possible to integrate ecosystem service tradeoffs into environmental decisions in a manner that respects the environmental rights of future generations.

La propuesta que nos hace Alfonso López Quintás, catedrático emérito de filosofía de la Universidad Complutense de Madrid y uno de los grandes pensadores españoles, en La ética o es transfiguración o no es nada, es la de emprender un camino de crecimiento personal. Forma parte esencial de nuestra existencia el crecimiento en una doble vertiente: biológica y espiritual. El crecimiento natural impone sus propios límites, a través de unas reglas que limitan nuestra vida. Sin embargo, los límites de nuestro crecimiento personal están íntimamente relacionados con el proceso mismo, que podemos llamar camino de la vida. Los límites de nuestro crecimiento irán apareciendo en el camino, pero el modo en el que recorremos nuestra senda vital es capital a la hora de determinar cómo recorreremos el camino que nos es propio. Esto es lo que nos plantea López Quintás en esta obra, cómo crecer a través del conocimiento de la propia realidad y de nuestra capacidad para transformarla.

Published: May 2020

Halocnemumstrobilaceum (Pall.) Bib. is a perennial grayish-green subshrub. The plant has rooting branches, which forms curtines up to two meters and belongs to salt-accumulating hypergalophytes. H. strobilaceum dominates desert and desert-steppe communities. Its cenopopulations spatial structure and ontogenetic composition can be used for analyzing the state of phytocenosis in general, but also for identifying features of living conditions. For example, H. strobilaceum is an indicator of gas and oil content (plant in this case is in a state of dwarfism and depression under conditions of high bituminosity), groundwater in the desert (thickets are formed), water body salinization, but primarily it‘s used as a permanent indicator of saline soils, because its development optimal is higher than 0.6–1.0 %. Ecological scales is one of those methods, which used to characterize the phytoindication properties of species coenopopulations. This study contains the investigation results of the cenopopulation of H. strobilaceum in the territory adjacent to the VAO “Himprom”, Kirov district, Volgograd city. The cenopopulation was characterized by such factors as soil moisture and acidity, cryoclimatic, thermoclimatic, salt regime, continental and arid climate, soil moisture variability, illumination / shading. Others research methods included Ripley‘s function and local density map. The study found that H. strobilaceumcenopopulation was aging and had a random spatial pattern, which indicates natural, stable living conditions, which means that it occupied its fundamental ecological niche. Under these conditions, the species is stenovalent to such parameters as illumination / shading, soil moisture variability and soil acidity. Therefore, H. strobilaceum can be used as a phytoindicator of the habitat by the above characteristics. Key words: cenopopulation, Halocnemumstrobilaceum, phytoindication, ecological scales, age states, Ripley‘s function, local density map.

COVID-19 pandemic has forced technology to evolve as the most challenging means of delivering teaching in addressing the cordon sanitaire. Technology has already been transforming most operation in medical education and secured strong footage in medical schools. NUMed, like any other higher educational institution, has started planning and implementing various strategies to ensure teaching is not hampered during this crisis. ReCaps, online tutorials, discussion boards, online seminars, webinars and quizzes were utilized in reflecting on the current situation. The paper assesses and mitigates the immediate change that has breached the boundaries of students and staffs to be engaged with strategic planning and adoption during the COVID-19 situation. This paper illustrates the interrelatedness and navigates across borders to leverage the possible planning and implementing educational technology as the pedagogical means to ensure the quality of medical education is preserved in fact enhanced through these strategies.

Bridging the Gap Between Probabilistic Model Checking and Probabilistic Planning: Survey, Compilations, and Empirical Comparison
Authors: Klauck Michaela , Steinmetz Marcel , Hoffmann Jörg , Hermanns Holger
Published: May 2020

Markov decision processes are of major interest in the planning community as well as in the model checking community. But in spite of the similarity in the considered formal models, the development of new techniques and methods happened largely independently in both communities. This work is intended as a beginning to unite the two research branches. We consider goal-reachability analysis as a common basis between both communities. The core of this paper is the translation from Jani, an overarching input language for quantitative model checkers, into the probabilistic planning domain definition language (PPDDL), and vice versa from PPDDL into Jani. These translations allow the creation of an overarching benchmark collection, including existing case studies from the model checking community, as well as benchmarks from the international probabilistic planning competitions (IPPC). We use this benchmark set as a basis for an extensive empirical comparison of various approaches from the model checking community, variants of value iteration, and MDP heuristic search algorithms developed by the AI planning community. On a per benchmark domain basis, techniques from one community can achieve state-ofthe-art performance in benchmarks of the other community. Across all benchmark domains of one community, the performance comparison is however in favor of the solvers and algorithms of that particular community. Reasons are the design of the benchmarks, as well as tool-related limitations. Our translation methods and benchmark collection foster crossfertilization between both communities, pointing out specific opportunities for widening the scope of solvers to different kinds of models, as well as for exchanging and adopting algorithms across communities.
Concrete confinement with TRM versus FRP jackets at elevated temperatures

Despite the clear cost, ease of installation, and construction schedule advantages of confinement of concrete structural elements with fibre-reinforced polymers (FRPs) for strength and deformability enhancement, concerns as to their performance at elevated temperature, or in fire, remain. The results of a series of elevated temperature experiments on FRP and textile reinforced mortar (TRM) strengthening systems for confinement of circular concrete columns are presented. The behaviour and effectiveness of the respective confining systems is studied up to temperatures of 400 °C. A total of 24 concrete cylinders were wrapped in the hoop direction with different amounts of FRP or TRM, heated to steady-state temperatures between 20 and 400 °C, and loaded to failure in concentric axial compression under a steady-state thermal regime. The results indicate that the effectiveness of the FRP confining system bonded with epoxy decreased considerably, but did not vanish, with increasing temperatures, in particular within the region of the glass transition temperature of the epoxy resin/adhesive. Conversely, the TRM confining system, bonded with inorganic mortar rather than epoxy, demonstrated superior performance than the FRP confining system at 400 °C as compared against tests performed at ambient temperature.

INTRODUÇÃO: Climatério é a passagem entre o período reprodutivo e não reprodutivo da mulher, caracterizado pelos fogachos e sudorese que geram alterações em sua qualidade de vida, podendo interferir no sono e nas atividades rotineiras. OBJETIVO: Avaliar a qualidade do sono e nível de insônia de mulheres no climatério e comparar com mulheres de ciclo menstrual regular.  MÉTODO: A coleta de dados foi realizada de janeiro a abril de 2018.  Foram coletados dados pessoais, data da última menstruação, uso de medicações, se pratica atividade física, uso de bebida alcoólica ou cigarro, além de dados antropométricos. Aplicou-se 3 questionários: o Índice Menopausal de Kupperman (IMK), aplicado nas mulheres que estavam no climatério; Índice de Qualidade do Sono de Pittsburgh (PSQI-BR) e o Índice de gravidade da insônia. RESULTADOS: A amostra foi constituída por 53 mulheres sendo 30 com ciclo menstrual regular e 23 no período do climatério. A média de idade foi de 45±9 anos, peso de 70±7 kg e altura de 158 ±4 cm. Observou-se que em relação à gravidade da sintomatologia climatérica, 61% das mulheres obtinham sintomas moderados e apresentavam qualidade do sono ruim onde apenas as mulheres no climatério foram avaliadas com presença de distúrbio do sono e 67% das mulheres que estavam no climatério obtinham insônia leve a moderada.  Houve diferença significativa entre a qualidade do sono (p=0,001) e a gravidade da insônia (p=0,014) entre os grupos. CONCLUSÕES: Mulheres climatéricas possuem pior qualidade do sono e insônia leve a moderada em comparação com mulheres que menstruam regularmente.
A intervenção fisioterapêutica na reabilitação pós cirurgia de redesignação de sexo masculino para feminino: relato de caso
Authors: Rose bezerra alves ferreira Barbara , Junio do Espirito Santo Carmo da Silva Flavio
Published: May 2020

DESCRIÇÃO DO CASO: Este relato de caso de uma mulher transexual, 48 anos de idade, com 15 anos de pós cirurgia de redesignação sexual (CRS) sem queixas. Durante a avaliação inicial foram coletados os dados sociodemográficos, avaliação da dor através da escala visual analógica visual (EVA), a qualidade de vida pelo SF-36, a função sexual pelo QS-F. Foi realizada a avaliação do assoalho pélvico (AP) inspeção, palpação e força seguindo o esquema PERFECT. Após a avaliação foram identificadas estenose vaginal, falta de consciência perineal, fraqueza dos músculos do assoalho pélvico e a relatou dor durante a relação sexual. INTERVENÇÃO: Foi sugerido um programa de exercícios através dos dilatadores vaginais, terapia comportamental, treino dos músculos do AP. O programa tinha por objetivo 10 sessões com 40 minutos de duração cada, duas vezes na semana. Ao final do programa foram coletadas a EVA, SF-36 e a avaliação do AP seguindo o esquema PERFECT. Entretanto, o QS-F não foi aplicado ao final do programa proposto devido a inatividade sexual da paciente por 3 meses, inclusive durante o tempo do programa. RESULTADOS: Após a avalição final a paciente apresentou melhora da consciência perineal, penetração via vaginal sem desconforto, entretanto, não houve melhora da força dos músculos do AP. CONSIDERAÇÕES FINAIS: A CRS promove alteração anatômica, podendo ocasionar disfunções urogenitais e/ou sexuais. Neste estudo, a fisioterapia promoveu melhora da conscientização perineal e da estenose vaginal. Com tudo, são necessários mais estudos sobre a fisioterapia nesta população, garantindo assistência e acompanhamento de forma adequada durante este processo, reduzindo suas possíveis complicações tardias.
