Results of the First BioASQ Workshop
Venue: BioASQ@CLEF
Year: 2013

The goal of the BioASQ project is to push the research frontier towards hybrid information systems. We aim to promote systems and approaches that are able to deal with the whole diversity of the Web, especially for, but not restricted to the context of bio medicine. This goal is pursued by the organization of challenges. The first challenge consisted of two tasks: semantic indexing and question answering. 157 systems were registered by 12 different participants for the semantic indexing task, of which between 19 and 29 participated in each batch. The question answering task was tackled by 15 systems, which were developed by three different organizations. Between 2 and 5 of these systems addressed each batch. Overall, the best systems were able to outperform the strong baselines provided in the experiments in two out of three settings. This suggests that advances over the state of the art were achieved through the BioASQ challenge but also that the benchmark in itself is very challenging. In this paper, we present the data used during the challenge as well as the technologies which were at the core of the participants' frameworks.
Continuing differentiation of human mesenchymal stem cells and induced chondrogenic and osteogenic lineages in electrospun PLGA nanofiber scaffold.
Venue: Biomaterials
Year: 2007

Nanofibers have recently gained substantial interest for potential applications in tissue engineering. The objective of this study was to determine whether electrospun nanofibers accommodate the viability, growth, and differentiation of human mesenchymal stem cells (hMSCs) as well as their osteogenic (hMSC Ob) and chondrogenic (hMSC Ch) derivatives. Poly(d,l lactide co glycolide) (PLGA) beads with a PLA:PGA ratio of 85:15 were electrospun into non woven fibers with an average diameter of 760+ 210 nm. The average Young's modulus of electrospun PLGA nanofibers was 42+ 26 kPa, per nanoindentation with atomic force microscopy (AFM) Human MSCs were seeded 1 4 weeks at a density of 2 x 10(6)cells/mL in PLGA nanofiber sheets. After 2 week culture on PLGA nanofiber scaffold, hMSCs remained as precursors upon immunoblotting with hKL12 antibody. SEM taken up to 7 days after cell seeding revealed that hMSCs, hMSC Ob and hMSC Ch apparently attached to PLGA nanofibers. The overwhelming majority of hMSCs was viable and proliferating in PLGA nanofiber scaffolds up to the tested 14 days, as assayed live/dead tests, DNA assay and BrdU. In a separate experiment, hMSCs seeded in PLGA nanofiber scaffolds were differentiated into chodrogenic and osteogenic cells. Histological assays revealed that hMSCs continuously differentiated into chondrogenic cells and osteogenic cells after 2 week incubation in PLGA nanofibers. Taken together, these data represent an original investigation of continuous differentiation of hMSCs into chondrogenic and osteogenic cells in PLGA nanofiber scaffold. Consistent with previous work, these findings also suggest that nanofibers may serve as accommodative milieu for not only hMSCs, but also as a 3D carrier vehicle for lineage specific cells.
High drug loading system of hollow carbon dots doxorubicin: preparation, in vitro release and pH targeted research.
Venue: Journal of materials chemistry. B
Year: 2019

Hollow carbon dots (HCDs) as drug carriers, and doxorubicin (DOX) as a model drug, were selected to prepare a HCDs DOX loading system. First, HCDs were prepared by a hydrothermal method and characterized by transmission electron microscopy (TEM) powder X ray diffraction (PXRD) and nuclear magnetic resonance (13C NMR) UV vis absorption, Fourier transform infrared (FT IR) and X ray photoelectron spectroscopies (XPS) The HCDs were then used to load DOX. The drug loading system of HCDs DOX was characterized by zeta potential measurements, and UV vis absorption and fluorescence spectroscopies. We then studied the drug loading, formation mechanism, cytotoxicity, in vitro release and pH targeted properties. HCDs DOX was found to have a high drug (DOX) loading ratio ~42.9% and better sustained pH targeted release and lower cytotoxicity than those of DOX. In the HCDs DOX system, interactions between the HCDs and DOX were electrostatic resulting in the formation of N[double bond, length as m dash]C via the coupling of NH2 (on HCDs) and C[double bond, length as m dash]O (on DOX) In vitro release of HCDs DOX conformed to the Weibull model and Fick diffusion, consistent with that of free DOX. We report, for the first time, that the: (i) functional groups on the HCD surfaces (not their hollow structure) play a key role in drug loading; (ii) the carrier (HCDs) did not change the in vitro release model or mechanism of DOX before and after loading by the HCDs.
Ansiedad ante el examen escrito en la materia de matematicas de estudiantes de dos escuelas secundarias del estado de Colima, Mexico
Year: 2014

espanolBausela (2005) senala que la ansiedad ante los examenes provoca un fracaso escolar en un gran numero de alumnos, no por tener problemas de aprendizaje, sino por los niveles de ansiedad que presentan ante estos. Marcuello (s.f. menciona que la ansiedad puede presentarse antes, durante y despues de un examen, en tres areas: nivel fisico, psicologico y de comportamiento. Podemos resaltar que los estudiantes sufren distintos trastornos antes y durante el examen escrito, que pueden alterar los resultados y provocar una calificacion negativa que en otras condiciones seria favorable. El presente estudio es transversal (Hernandez, Fernandez y Baptista, 2010) Se aplico el test de Reynolds y Richmond (1997) CMAS R (Escala de ansiedad manifiesta en ninos) Se aplico al test a 72 estudiantes en dos grupos, uno en situacion de examen y otro en clase regular. Los resultados muestran diferencias entre ambos grupos, obteniendo mayores niveles de ansiedad el grupo en situacion de examen. Las principales diferencias se observan en la ansiedad total y en la subescala inquietud/hipersibilidad. Asi, se comprueba que los estudiantes en condicion de examen tienen mayores niveles de ansiedad, siendo necesario disenar estrategias que les permita manejarla de forma efectiva, o considerar alternativas para la evaluacion. EnglishBausela (2005) indicates that test anxiety causes school failure in a large number of students, not by learning problems, but anxiety levels that come before them. Marcuello (sf) mentions that anxiety can occur before, during and after examination in three areas: physical, psychological and behavioral level. We can note that the students suffer various disorders before and during the written examination, which may alter the results and lead to a negative rating that in other circumstances would be favorable. The present study is cross sectional (Hernandez Fernandez and Baptista, 2010) Test Reynolds and Richmond (1997) CMAS R (Scale manifest anxiety in children) was applied. Test was applied to 72 students in two groups, one in a situation of exam and another regular class. The results show differences between groups, obtaining higher levels of anxiety in the group exam situation. The main differences were observed in overall anxiety and restlessness/hipersibilidadsubscale. Thus, is verified that students exam condition have higher levels of anxiety, being necessary to design strategies that allow them to manage it effectively, or consider alternatives for evaluation.
"I want my eyes." Blindness and Perception of the World in Polish Translations of Charles Dickens's The Cricket on the Hearth
Year: 2018

The article discusses Polish translations of Charles Dickens's The Cricket on the Hearth in terms of the vocabulary related to the blind girl Bertha, one of The Cricket's characters. The translations are compared and juxtaposed; the way their authors managed to talk about Bertha's disability is presented within the context of both political correctness and the practices of the Polish publishing houses in the twentieth century.
The SAGE Model of Social Psychological Research
Venue: Perspectives on psychological science a journal of the Association for Psychological Science
Year: 2018

We propose a SAGE model for social psychological research. Encapsulated in our acronym is a proposal to have a synthetic approach to social psychological research, in which qualitative methods are augmentative to quantitative ones, qualitative methods can be generative of new experimental hypotheses, and qualitative methods can capture experiences that evade experimental reductionism. We remind social psychological researchers that psychology was founded in multiple methods of investigation at multiple levels of analysis. We discuss historical examples and our own research as contemporary examples of how a SAGE model can operate in part or as an integrated whole. The implications of our model are discussed.
Neuropatogenesis inducida por el virus del sida: estrategias terapeuticas frente a la neurodegeneracion inducida por la glucoproteina gp120/Tat en el sistema nervioso central
Year: 2011

La neuroinflamacion constituye un proceso clave en la neuropatogenesis del virus del sida como consecuencia de la activacion aberrante de receptores de quimiocinas (CXCR4, CX3CR1 y CCR5) ya que la liberacion de citocinas proinflamatorias por las celulas infectadas amplifica la neurotoxicidad microglial y genera lipoperoxidos y especies reactivas de oxigeno que, en ultima instancia, danan la neurona. Por otro lado, la neurotoxina Tat induce alteraciones dendriticas por interaccion con el receptor LRP (receptor de lipoproteinas de baja densidad) e induce una excesiva estimulacion de los receptores de N metil D aspartato. Ademas, la interaccion aberrante de la glucoproteina gp120 con el receptor CXCR4 induce apoptosis dependiente de caspasa 3 (tambien libera ceramida) y activa las proteinas apoptoticas p53 y retinoblastoma como mecanismos neurotoxicos asociados a la disfuncion neural en el virus de la inmunodeficiencia humana 1 (VIH 1) Asimismo, la gliosis/activacion microglial y la liberacion de factores virales por los monocitos infectados, y el incremento de determinadas quimiocinas en el liquido cefalorraquideo (MCP 1 y fractalcina, entre otras) contribuyen a la neuropatogenesis del VIH 1. Por otro lado, se han detectado depositos de alfa sinucleina y de beta amiloide en cerebros post mortem de seropositivos de edad avanzada. Ademas, se han descrito varios marcadores sistemicos relacionados con los efectos degenerativos del virus y de sus neurotoxinas en el sistema nervioso central, tales como osteopontina, CD163 y fractalcina, entre otros. Por ultimo, se han realizado ensayos clinicos basados en estrategias protectoras relacionadas con la inhibicion de proteinas apoptoticas (inhibidores de GSK 3 beta) con inhibidores de la activacion microglial (minociclina) antioxidantes (selegilina) o factores troficos (IGF 1, hormona del crecimiento o eritropoyetina) que muestran efectos beneficiosos como tratamientos complementarios a la terapia antirretroviral.

Efficient Deep Neural Network for Photo realistic Image Super Resolution
Year: 2019

Recent progress in the deep learning based models has improved photo realistic (or perceptual) single image super resolution significantly. However, despite their powerful performance, many methods are difficult to apply to real world applications because of the heavy computational requirements. To facilitate the use of a deep model under such demands, we focus on keeping the network efficient while maintaining its performance. In detail, we design an architecture that implements a cascading mechanism on a residual network to boost the performance with limited resources via multi level feature fusion. In addition, our proposed model adopts group convolution and recursive scheme in order to achieve extreme efficiency. We further improve the perceptual quality of the output by employing the adversarial learning paradigm and a multi scale discriminator approach. The performance of our method is investigated through extensive internal experiments and benchmark using various datasets. Our results show that our models outperform the recent methods with similar complexity, for both traditional pixel based and perception based tasks.
A novel convolutional neural network based fault recognition method via image fusion of multi vibration signals
Venue: Comput. Ind.
Year: 2019

This paper proposed a novel fault recognition method for rotating machinery on the basis of multi sensor data fusion and bottleneck layer optimized convolutional neural network (MB CNN) A conversion method converting vibration signals from multiple sensors to images is proposed that can integrate information to get richer features than vibration signals from single sensor. By this method feature maps of different fault types can be obtained without tedious parameter adjustments. Based on the feature maps from multi sensor data, a corresponding novel convolutional neural network is also constructed. The constructed network performs the bottleneck layers with an increased number of input features to avoid information lost. The data at the same time node can be fused by the convolutional kernels of which the size matches the number of sensors. Practical examples of diagnosis for the wind power test rig and the centrifugal pump test rig are given in order to verify the effectiveness of the proposed approaches, and prediction accuracy of 99.47% and 97.32% is obtained respectively. Otherwise, the performances of other conventional methods such as deep belief network (DBN) support vector machine (SVM) and artificial neural network (ANN) are evaluated for contrast with the proposed method. As shown in the results, the novel convolutional neural network obtains higher recognition accuracy and faster convergence speed.
Covid 19: Mental health services must be boosted to deal with "tsunami" of cases after lockdown
Venue: BMJ
Year: 2020

Mental health should be a "core element" of the response to the covid 19 pandemic, with greater investment to cope with a predicted surge in cases after lockdown, say psychiatrists and the World Health Organization. A survey by the Royal College of Psychiatrists of 1369 of its members at the beginning of May found that 43% were seeing an increase in urgent and emergency cases, including patients who had suicidal thoughts or were self harming. At the same time 45% reported a fall in routine appointments, suggesting that self isolation, shielding, school closures, and fear of engaging with health services because of the risk of infection may be keeping patients away. Wendy Burn, president of the Royal College of Psychiatrists, said, "We are already seeing the devastating impact of covid 19 on mental health with more people in crisis.
Design Patterns and Extensibility of REST API for Networking Applications
Venue: IEEE Transactions on Network and Service Management
Year: 2016

REST architectural style has become a prevalent choice for distributed resources, such as the northbound API of software defined networking (SDN) As services often undergo frequent changes and updates, the corresponding REST APIs need to change and update accordingly. To allow REST APIs to change and evolve without breaking its clients, a REST API can be designed to facilitate hypertext driven navigation and its related mechanisms to deal with structure changes in the API. This paper addresses the issues in hypertext driven navigation in REST APIs from three aspects. First, we present REST Chart, a Petri Net based REST service description framework and language to design extensible REST APIs, and it is applied to cope with the rapid evolution of SDN northbound APIs. Second, we describe some important design patterns, such as backtracking and generator, within the REST Chart framework to navigate through large scale APIs in the RESTful architecture. Third, we present a client side differential cache mechanism to reduce the overhead of hypertext driven navigation, addressing a major issue that affects the application of REST API. The proposed approach is applied to applications in SDN, which is integrated with a generalized SDN controller, SOX. The benefits of the proposed approach are verified in different conditions. Experimental results on SDN applications show that on average, the proposed cache mechanism reduces the overhead of using the hypertext driven REST API by 66% while fully maintaining the desired flexibility and extensibility of the REST API.
Finite Element Simulation on NPGCS Precast Shear Wall Spatial Structure Model
Venue: Advances in Civil Engineering
Year: 2019

Seismic performance is basically required in precast shear wall. This study focuses on evaluation and improvement on precast shear wall seismic performance. By carrying out the finite element simulation on a precast shear wall spatial model with new connector from a practical high rise precast residential building, which was named as NPGCS and experimentally tested by low cyclic reversed lateral loads in early studies, the performance results including strengths, stiffness, stress, and concrete damage ratio distributions were obtained, and the reliability of NPGCS spatial model was verified. According to the testing results, the finite element simulation for the NPGCS spatial model is reliable and relatively accurate, especially for applying contact and beam elements into numerical analysis of precast interfaces and dowel shear actions, respectively. The strengths, stiffness, stress, and concrete damage ratio distributions from the simulation also supported the experimental results and conclusions.
Do early parental postnatal depression, attachment style and perceived social support affect neurodevelopmental outcomes of premature infants?
Venue: Infant behavior development
Year: 2020

The birth of a premature infant is both a stressful event for both parents and associated with an increased rate of postnatal depression (PND) Additionally some mothers may have delayed feelings of attachment to their babies because of the medical procedures or possible medical complications. Social support is known as an important factor for well being in the postnatal period. However there is scarce data about these factors for fathers. We aimed to identify the impact of parental PND, attachment style and social support on premature infant development considering the prematurity degree and risk groups.  This prospective study was conducted by including 96 infants who were born preterm. Mothers and fathers were given Edinburgh Postnatal Depression Scale (EPDS) Adult Attachment Style Scale (AASS) and Multidimensional Scale of Perceived Social Support (MSPSS) to fill out when their infants' corrected age was 3 months. The developmental evaluation was conducted with Bayley III at the corrected 6 months and 18 months of age.  Postnatal depression scores were more in mothers than fathers, the rates of secure attachment and social support were similar between mothers and fathers. Factors associated with the neurodevelopmental outcomes including prematurity degree and risk groups, EPDS, AASS and MSPSS scores were analyzed for both parents. In multivariate analysis, fathers' depression scores were inversely associated with cognitive development (p 0.030, R2 0.080, B= 0.283) and mothers' anxious/ambivalent attachment style was inversely associated with language development (p 0.011, R2 0.108, B= 0.329) at the age of corrected 6 months old.  Our findings underscore that the efforts to improve developmental outcomes of premature infants should include parental well being taking into account new fathers' depressive symptomatology and maternal anxious/ambivalent attachment.
A comparison of technologies for remediation of heavy metal contaminated soils
Year: 2017

Soil contamination with persistent and potentially (eco)toxic heavy metal(loid)s is ubiquitous around the globe. Concentration of these heavy metal(loid)s in soil has increased drastically over the last three decades, thus posing risk to the environment and human health. Some technologies have long been in use to remediate the hazardous heavy metal(loid)s. Conventional remediation methods for heavy metal(loid)s are generally based on physical, chemical and biological approaches, which may be used in combination with one another to clean up heavy metal(loid) contaminated soils to an acceptable and safe level. This review summarizes the soil contamination by heavy metal(loid)s at a global scale, accumulation of heavy metal(loid)s in vegetables to toxic levels and their regulatory guidelines in soil. In this review, we also elucidate and compare the pool of available technologies that are currently being applied for remediation of heavy metal(loid) contaminated soils, as well as the economic aspect of soil remediation for different techniques. This review article includes an assessment of the contemporary status of technology deployment and recommendations for future remediation research. Finally, the molecular and genetic basis of heavy metal(loid) (hyper)accumulation and tolerance in microbes and plants is also discussed. It is proposed that for effective and economic remediation of soil, a better understanding of remediation procedures and the various options available at the different stages of remediation is highly necessary.
AN ETHICAL MARKETING PERSPECTIVE: CORPORATE SOCIAL RESPONSIBILITES FOR STRENGTHENING CORPORATE BRAND MANAGEMENT (STUDY CASE IN FAST MOVING CONSUMER GOODS
Year: 2020

In this 21st century perspective of marketing strategy for strengthening brand management are very important in business. Using principal of business ethic focusing ini ethical marketing will help stong brand in consumer mind. Ethical marketing activities are shown in Corporate Social Responsibilites affect Brand Strengthening. In recent years the surrounding world has had an increased interest, focus and demand for responsibility and sustainability. Therefore, A corporation's formulation of its ideal identity should reflect how the firm wants to deal with the social and environmental aspects of its business. This first step is the most difficult one because a firm's management has to adapt the definition of the desired identity to the ideal identity, whereas management is predisposed to strive for their conception of the desired identity. For instance, the desired identity may be that management wants to develop an excellent sustainable business, whereas the consumer does not reward the efforts that are made in this respect. The reflection on the ideal identity with respect to CSR should lead to a choice for one or more of the following CSR strategies: reputation management, building a virtuous corporate brand, and ethical product differentiation. As the result, the brand will win the consumer mind according to the marketing research from well known market research companies in Indonesia.
