Abstract
Patellofemoral pain syndrome (PFPS), the most common source of knee pain among physically active individuals, is defined as anterior knee pain involving the patella and retinaculum that excludes other intraarticular and peri-patellar pathology. Differences in the activation and endurance of the quadriceps components, causing an imbalance in the forces controlling patellar tracking during flexion and extension in the knee joint, appear to be the most commonly reported risk factors for PFPS. The aim of this study was to determine the differences in bioelectric activity of vastus medialis and rectus femoris muscles during half knee bend position in runners with PFPS. The sample comprised 20 recreational runners (15 males, 5 females; aged 27 ± 5 years) reporting knee pain and diagnosed with PFPS. The age- and sex-matched control group consisted of recreational runners who did not report knee pain. The myon electromyographic system was used to determine the changes in the electromyographic median frequency during a half squat position. The decrease in the median frequency of vastus medialis and rectus femoris muscles was significantly greater in runners with PFPS in comparison to the control group (p < 0.01 for right and left vastus medialis and right rectus femoris; p < 0.05 for left rectus femoris). There is a relationship between knee pain related to PFPS and the imbalance of bioelectric activity of vastus medialis and rectus femoris muscles. Achieving the muscular balance within the thigh muscles can be an important factor in the rehabilitation process of PFPS.

Abstract
The rectus femoris (RF) has a region-specific functional role; that is, the proximal region of the RF contributes more than the middle and distal regions during hip flexion. This study aimed to investigate whether RF strain injury affected the region-specific functional role of the muscle. We studied seven soccer players with a history of unilateral RF strain injury. Injury data were obtained from a questionnaire survey and magnetic resonance imaging (MRI). Multichannel surface electromyographic (SEMG) signals were recorded from the proximal to distal regions of the RF with 24 electrodes during isometric knee extension and hip flexion. The SEMG signals of each channel during hip flexion were normalised by those during knee extension for the injured and non-injured RF (HF/KE), and compared among the proximal, middle, and distal regions. Six RF strain injuries showed a low signal area in MRI. There was no significant difference in muscle strength between the injured and non-injured RF. While the HF/KE in the proximal region was significantly higher than those in the middle and distal regions in the non-injured RF, a difference in the HF/KE was seen only between the proximal and distal regions of the injured RF. Furthermore, the HF/KE of the most proximal channel in the injured RF was significantly lower than that in the non-injured RF. However, there was no significant difference between injured and non-injured areas in the HF/KE. Our findings suggest that the region-specific functional role of the RF muscle is partly affected by RF strain injury.

Abstract
The aim of this study was to compare the acute effects of performing half squats (HSs) with different loading intensities (1, 3, and 5 repetitions maximum [RM], and 60% 1RM) and a different number of sets (1, 2, and 3) on the countermovement jump (CMJ) performance of 18 highly-trained male subjects. Participants were submitted to four experimental conditions (1RM, 3RM, 5RM, and 60% 1RM) in randomized order. The CMJ was assessed before and after each set. Differences in CMJ performance between the distinct experimental conditions and individual responses in CMJ performance induced by the different protocols were analyzed via the magnitude-based inference method. Overall, significant improvements were detected in individual CMJ heights after each activation protocol. It can be concluded that the use of 1 to 3 sets of HSs performed at moderate-to-high loads may be an effective strategy to improve jump performance in highly-trained subjects. Nevertheless, despite the high efficiency of the protocols tested here, coaches and researchers are strongly encouraged to perform individualized assessments within the proposed range of loads and sets, to find optimal and tailored post-activation potentiation protocols.

This paper describes some fusion techniques for achieving high accuracy species identification from images of different plant organs. Given a series of different image organs such as branch, entire, flower, or leaf, we firstly extract confidence scores for each single organ using a deep convolutional neural network. Then, various late fusion approaches including conventional transformation-based approaches (sum rule, max rule, product rule), a classification-based approach (support vector machine), and our proposed hybrid fusion model are deployed to determine the identity of the plant of interest. For single organ identification, two schemes are proposed. The first scheme uses one Convolutional neural network (CNN) for each organ while the second one trains one CNN for all organs. Two famous CNNs (AlexNet and Resnet) are chosen in this paper. We evaluate the performances of the proposed method in a large number of images of 50 species which are collected from two primary resources: PlantCLEF 2015 dataset and Internet resources. The experiment exhibits the dominant results of the fusion techniques compared with those of individual organs. At rank-1, the highest species identification accuracy of a single organ is 75.6% for flower images, whereas by applying fusion technique for leaf and flower, the accuracy reaches to 92.6%. We also compare the fusion strategies with the multi-column deep convolutional neural networks (MCDCNN) [1]. The proposed hybrid fusion scheme outperforms MCDCNN in all combinations. It obtains from + 3.0% to + 13.8% improvement in rank-1 over MCDCNN method. The evaluation datasets as well as the source codes are publicly available.

Abbreviation Detection in Vietnamese Clinical Texts
Authors: Vo Chau , Cao Tru , Ho Bao 
Published: April 2019

Abbreviations have been widely used in clinical notes because generating clinical notes often takes place under high pressure with lack of writing time and medical record simplification. Those abbreviations limit the clarity and understanding of the records and greatly affect all the computer-based data processing tasks. In this paper, we propose a solution to the abbreviation identification task on clinical notes in a practical context where a few clinical notes have been labeled while so many clinical notes need to be labeled. Our solution is defined with a semi-supervised learning approach that uses level-wise feature engineering to construct an abbreviation identifier, from using a small set of labeled clinical texts and exploiting a larger set of unlabeled clinical texts. A semi-supervised learning algorithm, Semi-RF, and its advanced adaptive version, Weighted Semi-RF, are proposed in the self-training framework using random forest models and Tri-training. Weighted Semi-RF is different from Semi-RF as equipped with a new weighting scheme via adaptation on the current labeled data set. The proposed semi-supervised learning algorithms are practical with parameter-free settings to build an effective abbreviation identifier for identifying abbreviations automatically in clinical texts. Their effectiveness is confirmed with the better Precision and F-measure values from various experiments on real Vietnamese clinical notes. Compared to the existing solutions, our solution is novel for automatic abbreviation identification in clinical notes. Its results can lay the basis for determining the full form of each correctly identified abbreviation and then enhance the readability of the records.

El concepto de cultura como clave para el análisis de la relación entre las subjetividades e instituciones en G. Deleuze
Authors: Gulino Pablo Martín 
Published: April 2019

<p>El presente trabajo pretende señalar al concepto de cultura expresado en la obra Nietzsche y la filosofía de G. Deleuze, como una clave para comprender la producción de subjetividades e instituciones así como la relación entre ambas. De este modo, pretendemos señalar a la cultura como el elemento que nos muestra la compleja trama de fenómenos en la que se ve envuelta la producción de sujetos e instituciones. Así también, y en relación con esta complejidad, se inscribe una manera no causal de comprender la relación entre las instituciones y los sujetos. De esta forma, entendemos que la cultura puede ser entendida como el concepto que nos permite observar la complejidad que esconde la producción de sujetos e instituciones así como su relación no lineal entre estas.</p><p> </p>
El biopoder patriarcapitalista y la destrucción de la masculinidad. La resistencia en clave femenina y feminista
Authors: Bordón Gabriele Camila V. 
Published: April 2019

<p>El feminismo permite nuevas formas de interpretar la propuesta foucaultiana sobre la biopolítica. El biopoder se emplaza en una estructura patriarcapitalista, heredera del Estado moderno, donde sus mecanismos de control de la población se vuelven claves en el cuerpo percibido femenino o cuerpa, término apropiado por el feminismo contemporáneo. El entramado de luchas no es solo en política, en términos de esfera pública, sino que la vista se vuelve sobre el espacio doméstico, lugar que históricamente se asocia y se restringe a la feminidad. En él hay cuatro mecanismos representativos: el sexo falocéntrico, el aborto, el parto y el feminicidio. Estos mecanismos disponen fuerzas productivas en el trabajo, en una lógica binaria, jerárquica y sexual. Operan como estrategias dos figuras, tomadas de la antropóloga Rita Segato, el varón moralizador y la mujer sospechosa. El análisis del juego poder-resistencia permite el encuentro de puntos de fuga. El espacio de lucha es principalmente el lugar doméstico, lo privado o lo íntimo, lo otro binario en relación al Estado y al interés público. La resistencia es al saber normalizador de las prácticas de lo cotidiano, que significa normalizar sobre los cuerpos y la vida principalmente de mujeres e identidades que se perciban femeninas.</p><p> </p>

Abstract
However, while low pressure carburizing (LPC) is now well established for smaller components and conventional conditions (up to 980 °C), a number of difficulties are expected when considering high temperature LPC of large components. First, conventional carburizing steels will undergo extensive grain growth during an exposure to 1050 °C for 20 hours; while there are solutions to avoid the problem for shorter durations, there are no materials adapted to such heat-treatment durations. Second, the long exposure at high temperature means that the possibility of significant creep deformation should be considered. And third, the hardenability of the material commonly used for wind turbine gears (18CrNiMo7-6) may not be sufficient when switching from oil to gas quenching. The present work attempts to address these issues. On the basis of theoretical alloy design, numerical modeling and experimental work, two purposely designed steel compositions were industrially cast. They were used to manufacture large wind turbine gears and extensively tested. Experimental results are compared to those obtained with a standard 18CrNiMo7-6. Based on a full analysis of the possible production routes, a cost benefit of 20 % is estimated by switching from the actual to the newly developed manufacturing route.

Prophylactic regimens with fluconazole for candidiasis in neonates under 1.500g: A retrospective chart review of two cohorts
Authors: Silva-Rios J. , Camargos P. , Correa L. , Romanelli R. 
Published: April 2019

BACKGROUND: The incidence rate of invasive candidiasis in newborns with birth weight below 1,500 g ranges from 2% to 8%, and fluconazole prophylaxis in neonatal units is recommended when the incidence of invasive candidiasis is higher than 5%. This study aimed to compare the effectiveness of targeted prophylaxis and universal prophylaxis with fluconazole in the prevention of invasive candidiasis. METHODS: This was a historical cohort comparing the targeted prophylaxis for newborns weighing less than 1,500 g and the universal prophylaxis for newborns weighing less than 1,000 g. RESULTS: The overall incidence rate of invasive candidiasis was 5.25% and was reduced from 7.1% to 3.72% with universal prophylaxis ( p = 0.04). In a multivariate analysis, the significant factors associated with the development of candidiasis were birth weight less than 1,000 g, prolonged hospitalization, previous surgery, prolonged use of mechanical ventilation, prior exposure to antimicrobial treatments, and use of targeted prophylaxis. CONCLUSIONS: Universal prophylaxis had lower incidence of invasive candidiasis, and preventive measures considering the risk factors are mandatory to reduce the incidence of invasive candidiasis.
