Construção De Detector De Estímulo Com Neurônio Pulsante Via Evolução Diferencial

Computational neuroscience seeks to understand the mechanisms and functions of the nervous system through the construction of realistic mathematical models of neural networks and the realization of large-scale computer simulations. However, the creation of these mechanisms are still a distant reality, and thus, current research has sought to reproduce, in general, simple tasks of the nervous system. Therefore, The Izhikevich spiking neuron model was chosen because of their excellent performance computing, while preserving many of the desirable biological features. Thus, this paper proposes the construction of detectors based on Izhikevich spiking neuron model, who are able to detect external stimuli, i.e., to pulse when they are stimulated by current pulses from the external environment. For this, we have performed a set of simulations involving tuning the parameters of the Izhikevich spiking neuron model, as well as tuning the magnitude of current stimulation via the method of differential evolution optimization. As a result, it was possible to find a set of solutions that automatically adjust the parameters of the spiking neuron, so that it behaves as a stimuli detector. Furthermore, based on sample average rate of correct solutions obtained in the first set of simulation, four among the best solutions were selected in order to validate and analyze the average success rates depending on the values of probability of occurrence of stimuli. It is hoped that these results will contribute to a better analysis of the behavior of artificial neurons in the construction of sensors with greater biological plausibility.
A Numerical Model for Oil/Water Separation from a Solid Particle

A NUMERICAL MODEL FOR OIL/WATER SEPARATION FROM A SOLID PARTICLE Eric Sheung-Chi Fan Master of Applied Science Department of Mechanical & Industrial Engineering University of Toronto 2010 A computational fluid dynamics model has been developed to study an oil-coated particle immersed in a uniform aqueous flow, to determine the conditions that favour oil separation. The governing flow equations are discretized using a finite volume approach, and the oil/water interface is captured using the Volume-of-Fluid (VOF) method in a 2D spherical coordinate system. The model predicts different mechanisms for oil separation. At a Reynolds number, Re, equal to 1, and at a low capillary number, Ca ¿ 1, the high interfacial tension can induce rapid contact line motion, to the extent that the oil film can advance past its equilibrium position and separate from the particle. This mechanism requires that the contact angle measured through the oil phase is large. On the other hand, as Ca approaches 1, the shear exerted by the external flow stretches the oil into a thread that will eventually rupture and separate.
MELODIES, MEMORIES, AND MEANING: THE USE OF MUSIC THERAPY FOR PERSONS WITH DEMENTIA

Dementia is a growing public health issue, as there are 24.3 million people currently diagnosed worldwide. Being that there is no cure, non-pharmacological interventions are important to optimize quality of life for this population. Music therapy is a nonpharmacological intervention with fine usability for dementia patients. This thesis will examine the positive effects of music therapy on the behavioral symptoms, mood management, self-esteem, language skills, cognition, and reminiscence for the individual with dementia based on existing literature and will provide practice recommendations for the clinical use of music therapy and research. A short literature review will focus on the field of visual art therapy, for the purpose of examining the effect and usability of the fine arts as non-pharmacological interventions.
Meta-Gig: Empowering anyone to create crowd marketplaces

Few have the power to create crowd markets. Existing marketplaces may thus not embody workers’ or requesters’ needs. In this paper, we imagine a future where anyone could create the crowd markets they desire. We study the characteristics of the markets that 40 workers and 40 requesters from Amazon Mechanical Turk propose. We uncover that workers pushed for marketplaces that either empowered workers to set their own salaries without requiring a minimum wage or had intelligent algorithms that could automatically decide the salaries while also ensuring everyone received a minimum wage. Requesters were consistent in their preference of paying by commission and preferred markets that automatically set the salary. Both workers and requesters advocated for mechanisms to ensure quality and flexible time schedules in the market. We conclude by discussing design implications from our findings.

A Critique of the Agrarian Policies under Neoliberalism: Reasons for Agrarian Distress in the Current Indian Context

The National Agricultural Policy of the Ministry of Agriculture, Government of India (2000), said: “Agriculture has become a relatively unrewarding profession due to a generally unfavourable price regime and low-value addition, causing abandoning of farming and increasing migration from rural areas. The situation is likely to be exacerbated further in the wake of integration of agricultural trade in the global system, unless immediate corrective measures are taken. ” Throughout the course of this essay, we examine the agrarian crisis in India in the neoliberal era i.e. the impact on land holdings, credit availability, pricing policy etc. We also discuss the impact of such policies on both farmers and agricultural labourers with some focus on female agricultural workforce to capture the gender dimension.

The Uncertainty of Tropical Cyclone Intensity and Structure Based on Different Parameterization Schemes of Planetary Boundary Layer

Based on different parameterization schemes of planetary boundary layer (PBL), the uncertainty of intensity and structure of the Super-strong Typhoon Rammasun (1409) is investigated using the WRF model (v3.4) with six PBL parameterization schemes. Results indicate that PBL uncertainty leads to the uncertainty in tropical cyclone (TC) prediction, which increases with forecast time. The uncertainty in TC prediction is mainly reflected in the uncertainty in TC intensity, with significant differences in the TC intensity forecasts using various PBL schemes. The uncertainty in TC prediction is also reflected in the uncertainty in TC structures. Greater intensity is accompanied by smaller vortex width, tighter vortex structure, stronger wind in the near-surface layer and middle and lower troposphere, stronger inflow (outflow) wind at the lower (upper) levels, stronger vertical upward wind, smaller thickness of the eye wall, smaller outward extension of the eye wall, and warmer warm core at the upper levels of eye. PBL height, surface upward heat flux and water vapor flux are important factors that cause the uncertainty in TC intensity and structure. The more surface upward heat flux and water vapor flux and the lower PBL height, the faster TC development and the stronger TC intensity.
The Relevance Of Acceptance And Commitment Therapy (ACT) In The Treatment Of Emotional Numbing Among The Adolescents: A Narrative Review

The issue of emotional numbing is a serious emotional challenge among the adolescents and which is greatly impacting on them negatively and sometimes goes unnoticed until the damage is done. The study explored the concept of emotional numbing, its symptoms and the causes for a clear understanding of the phenomenon. It also examined the Acceptance and Commitment therapy (ACT), its core processes as a suitable therapeutic property to resolve the emotional problem of the adolescents who go through such pain. The ACT is a process and mindfulness model which promotes psychological flexibility through fostering openness, awareness and engagement as illustrated in its six core processes. It was observed that the ACT promotes emotional awareness through the functions of the six core processes of the ACT model and as a result, could be adopted to manage the challenges of emotional numbing among the adolescents. The researchers therefore recommend that the therapists identify such adolescents in the schools and address their issues with the ACT model.
Aspergillus fumigatus-derived demethoxyfumitremorgin
 C inhibits proliferation of PC3 human prostate cancer cells through
 p53/p21-dependent G1 arrest and apoptosis induction

Human prostate cancer is the second most frequently diagnosed cancer worldwide, and its incidence rate continues to increase. Advanced prostate cancer is more difficult to treat than early forms due to its chemotherapy resistance. There is need for more effective agents that can inhibit the progression of advanced prostate cancer. Demethoxyfumitremorgin C (DMFTC) was isolated from the fermentation extract of the marine fungus Aspergillus fumigatus. Antiproliferative activity of DMFTC against human prostate cancer PC3 cells was examined through cell cycle analysis by flow cytometry, the fluorescent nuclear imaging analysis with propidium iodide (PI), and proteins expression related to cell cycle arrest and apoptosis were investigated via Western blotting. DMFTC inhibited PC3 cells growth through G1 phase cell cycle arrest and apoptosis induction. It activated the tumor suppressor p53 and the Cdk inhibitor p21, which regulate the cell progression into the G1 phase. Additionally, PI-positive late apoptotic non-viable cells were increased and the expression levels of the G1-positive downstream regulators cyclin D, cyclin E, Cdk2, and Cdk4 were decreased by DMFTC treatment. These results suggest that DMFTC induces G1 arrest and apoptosis induction through regulation of p53/p21-dependent cyclin-Cdk complexes, and it may be a useful therapeutic agent for the treatment of human advanced prostate cancer.
GIS Approach for the Analysis of the Socio-Sanitary Stakes of Water Use in the Lobo Watershed in Nibehibe (Central-Western Côte d'Ivoire)

Water is a precious natural resource that is essential for many uses, but its quality is faced with several problems, including pollution linked to human activities, hence the need to contribute to improving the quality of drinking water. Given the importance of the resource, the health of the population in terms of hygiene needs and the quality of the water consumed is paramount. It is within this framework that this work falls within the scope of this project, the objective of which is to analyze the health impacts to which the populations are exposed due to the use of water in the Lobo watershed in Nibéhibé. To achieve this objective, the working method was based on literature review and field surveys. The documentary research consisted in circumscribing the contours of the subject in order to better understand it. As for the field surveys, they were dominated by interviews and a questionnaire addressed to households and health structures. Using the simple random selection method without discount and the use of a statistical equation, we found a sample of 384 households to be surveyed, distributed in three departments (Daloa, Vavoua and Zoukougbeu). Population surveys, combined with spatially referenced data under GIS, made it possible to assess not only the spatial distribution of the importance of water-related diseases, but also the areas at health risk. The results highlighted health risk indicators that expose households to water-related diseases linked to the mode of water supply. Also, the contraction of these diseases by households is due to the uncontrolled use of multiple uses and the risky behavior of the population with regard to hygiene and sanitation practices. In addition, we note that those in rural areas are the most affected because of the insufficient level of access to drinking water and adequate sanitation. Thus, these diseases cause great loss of human life and contribute to the disorganization of the social structure.
Thermo-Optical Effects in Plasmonic Metal Nanostructures

The effects of the temperature on the surface plasmon resonance (SPR) in noble metal nanoparticles at various temperatures ranging from 77 to 1190 K are reviewed. A temperature increase results in an appreciable red shift and leads to a broadening of the SPR in the nanoparticles (NPs). This observed thermal expansion along with an increase in the electron-phonon scattering rate with rising temperature emerge as the dominant physical mechanisms producing the red shift and broadening of the SPR. Strong temperature dependence of surface plasmon enhanced photoluminescence from silver (Ag) and copper (Cu) NPs is observed. The quantum photoluminescence yield of Ag nanoparticles decreases as the temperature increases, due to a decrease in the plasmon enhancement resulting from an increase in the electron-phonon scattering rate. An anomalous temperature dependence of the photoluminescence from Cu nanoparticles was also observed; the quantum yield of photoluminescence increases with the temperature. The interplay between the SPR and the interband transitions plays a critical role in this effect. The surface-plasmon involved laser heating of a dense 2D layer of gold (Au) NPs and of Au NPs in water colloids is also examined. A strong increase in the Au NP temperature occurs, when the laser frequency approaches the SPR. This finding supports the resonant plasmonic character of the laser heating of metal NPs. The sharp blue shift of the surface plasmon resonance in colloidal Au NPs at temperatures exceeding the water boiling point indicates the vapor-bubble formation near the surface of the NPs. K e yw o r d s: metal nanoparticles, surface plasmon resonance, temperature effects, electronphonon scattering, nanoparticle thermal expansion, plasmon enhanced photoluminescence, light-induced heating.
