A functionalized fluorochrome based on quinoline benzimidazole conjugate: From facile design to highly sensitive and selective sensing for picric acid
Venue: Dyes and Pigments
Year: 2019

Two important fluorophores (quinoline and benzimidazole) have been successfully combined to achieve a novel fluorochrome with desirable fluorescent performance in solution and solid state. This original fluorochrome exhibits not only visual fluorescence quenching toward picric acid (PA) over other nitroaromatics and common interferents, but also ppb level (4.86 ppb) of detection limit in semi aqueous solution. In addition, the other sensing properties such as rapid response (second level) good environmental compatibility (pH tolerability) and sensitivity are also evidentially revealed. The dominant quenching mechanism involves a synergistic effect of inner filter effect and photoinduced electron transfer (PET) which is fully supported by spectral analysis, 1H NMR assay, morphological studies, lifetime experiments and theoretical calculation. Noteworthily, the fluorochrome can be readily used in real water samples for quantitative determination of PA and processed as fluorescent paper or thin layer chromatography (TLC) plate for naked eye detection, which enable itself to be functionalized as applicable PA sensor.
Research on Anomaly Detection Method Based on DBSCAN Clustering Algorithm
Venue: 2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT)
Year: 2020

With the rapid development of Internet technology and communication technology, more and more computer systems and networks have been maliciously attacked by intruders. Network security has been seriously threatened to a certain extent, and network security technology has also attracted more and more attention from the public. As a security protection technology for actively monitoring network data, intrusion detection technology effectively compensates for the defects of traditional security protection technologies such as firewalls and data encryption, and has become an important research field in network security. Based on this, it is very important to design the security mechanism of the system to prevent unauthorized access to system resources and data. This paper uses a DBSCAN algorithm for anomaly detection clustering algorithm. Algorithms that can be used for massive data processing have become a research hotspot in anomaly detection. Normal behavior profiles are formed on audit records and adjusted in time as program behavior changes. Experimental results show that, compared with other algorithms, anomaly detection based on the DBSCAN algorithm can improve the detection rate of the data set, and significantly improve the accuracy of anomaly detection.
Una ciudad para todos: accesibilidad cognitiva en el espacio publico
Year: 2020

La accesibilidad cognitiva ha sido la gran olvidada por nuestra sociedad, tanto desde el punto de vista normativo como arquitectonico, y mas aun, en el ambito del urbanismo. Para que el mayor numero de personas puedan alcanzar de forma segura la autonomia fisica, sensorial y cognitiva, e deben evitar los impedimentos que suponen las barreras fisicas o de percepcion. Partiendo del concepto de accesibilidad universal y centrandome en la cognitiva, he realizado mi trabajo sobre el estudio de la misma en los Jardines del Buen Retiro, por ser un espacio publico utilizado por todo tipo de personas, y con un amplio abanico de posibilidades de ocio y cultura. He tratado de localizar esas barreras que merman la accesibilidad cognitiva del parque, para posteriormente disenar unas propuestas que pudieran resolver estos impedimentos. La base de la accesibilidad cognitiva de un espacio tiene su origen en un buen diseno del mismo, que puede apoyarse en referencias multimodales. En el caso de una arquitectura existente que no haya sido bien disenada, se debera contemplar todo un sistema de apoyos que orienten y direccionen. Es labor del arquitecto disenar entornos que contemplen unos apoyos espaciales con un lenguaje comprensible, que hagan el espacio mas facil para todos.
The Fennel, Foeniculum vulgare incorporated diet shows anxiolytic potential: A pre clinical study.
Venue: Pakistan journal of pharmaceutical sciences
Year: 2019

This novel study was conducted with objective to evaluate the anxiolytic potential of whole crushed seeds of Foeniculum vulgare (FV) which were incorporated in diet. Albino mice were divided in three groups: Control group, Study group 2% FV and Study group 4% FV, each having 10 mice. Special dietary pellets containing whole crushed Foeniculum vulgare seeds were prepared in 2% and 4% ratio, respectively and were fed to respective Study groups whereas Control group was given regular rodent diet for 2 months. Animal behaviour was assessed using Home Cage Activity test, Head Dip test, Light and Dark Box test and Open Field test at intervals of 15 days for a period of 2 months. The results of this study showed, decrease in Cage Crossing activity, more number of Head Dips, increased time spent in Light box and increase in number of transitions between Light and Dark Box, increased number of Central Squares Crossed and increased time spent in Central Squares of Open Field arena for both study groups in comparison with control group. Foeniculum vulgare whole crushed seeds diet of 2% and 4% was found to have anxiolytic effect.
Numerical and Neural Network Analysis of Natural Convection from a Cold Horizontal Cylinder above an Adiabatic Wall
Venue: Journal of Applied Fluid Mechanics
Year: 2019

Free convection around cold circular cylinder above an adiabatic plate at steady state condition has been investigated both numerically and by artificial neural networks. There is a growing demand for a better understanding of free convection from a horizontal cylinder in the areas like air cooling, refrigeration and air conditioning system, etc. Governing equations are solved in some specified cases by finite volume method to generate the database for training the neural network in the range of Rayleigh numbers of 10 to 10 and a range of cylinder distance from adiabatic plate (L/D) of 1/4, 1/2, 1/1, 3/2 and 4/2, thereafter a Multi Layer Perceptron network is used to capture the behavior of flow and temperature fields and then generalized this behavior to predict the flow and temperature fields for other Rayleigh numbers. Different training algorithms are used and it is found that the back propagation method with Levenberg Marquardt learning rule is the best algorithm regarding the faster training procedure. It is observed that ANN can be used more efficiently to determine cold plume and thermal field in less computational time and with an excellent agreement. From obtained results, average Nusselt number of the cylinder investigated to study the effect of adiabatic wall on the isothermal cylinder. It also observed that in spaces farther than L/D 3/2, average Nusselt number is almost constant, so the affect is renouncement and it works like a cylinder in an infinite environment.

A FUN SCALE for Understanding the Hedonic Value of a Product: The Destination Context
Year: 2016

Fun" is one of the most frequently referenced sensory and hedonic phenomena in many different contexts of life, which merits scientific attention especially when consumer behavior is investigated with an experiential view of consumption. However, scientific definition and measurement of "fun" is virtually non existent in literature. Thus, this study aims to develop a scale of fun with structural (underlying dimensions) and psychometric (reliability and validity) properties to assess the hedonic value of a destination as a product. Several stages of content analysis, data collection, exploratory factor analysis and confirmatory factor analysis for scale purification resulted in a FUN SCALE with 12 items assembling into four factors that were named social vigor, psychological zest, emotional spark, and flow.
A Novel Detector Based on Convolution Neural Networks for Multiscale SAR Ship Detection in Complex Background
Venue: Sensors
Year: 2020

Convolution neural network (CNN) based detectors have shown great performance on ship detections of synthetic aperture radar (SAR) images. However, the performance of current models has not been satisfactory enough for detecting multiscale ships and small size ones in front of complex backgrounds. To address the problem, we propose a novel SAR ship detector based on CNN, which consist of three subnetworks: the Fusion Feature Extractor Network (FFEN) Region Proposal Network (RPN) and Refine Detection Network (RDN) Instead of using a single feature map, we fuse feature maps in bottom up and top down ways and generate proposals from each fused feature map in FFEN. Furthermore, we further merge features generated by the region of interest (RoI) pooling layer in RDN. Based on the feature representation strategy, the CNN framework constructed can significantly enhance the location and semantics information for the multiscale ships, in particular for the small ships. On the other hand, the residual block is introduced to increase the network depth, through which the detection precision could be further improved. The public SAR ship dataset (SSDD) and China Gaofen 3 satellite SAR image are used to validate the proposed method. Our method shows excellent performance for detecting the multiscale and small size ships with respect to some competitive models and exhibits high potential in practical application.
Economic Growth and Income Inequality: Evidence from Dynamic Panel Investigation
Year: 2016

This paper empirically investigates the effect of income inequality on economic growth using extended panel data covering a broad range of developing and developed countries. We use system generalized method of moments (GMM) techniques in a dynamic panel analysis, which alleviates the possible positive bias in difference GMM due to the persistence of lagged dependent variables as instruments. We find strong evidence of a negative effect on growth from income inequality, which contradicts the findings of Forbes [2000, September. A reassessment of the relationship between inequality and growth, American Economic Review, 90(4) pp. 869 887] and Li and Zou [1998, October. Income inequality is not harmful for growth: Theory and evidence, Review of Development Economics, 2(3) pp. 318 34] Further analyses using combined Gini coefficients show that the difference can be overall attributed to the problem of omitted control variables and the differences in how the variations in inequality across countries are reflected. We also find that the negative effects of inequality on economic growth can be of great significance when using a sample of less developed countries or more recent inequality data set.

Financing online retailers: Bank vs. electronic business platform, equilibrium, and coordinating strategy
Venue: Eur. J. Oper. Res.
Year: 2019

We consider a new financing source for online retailers, namely an electronic business (EB) platform, which is divided into an active and a conservative form according to the level of integration of lending and leasing businesses. The newsvendor like online retailer is capital constrained and can choose between EB platform financing and bank credit financing (BCF) We model their interaction as a Stackelberg game, where the online retailer functions as the follower who decides the order quantity and the lender (bank or EB platform) functions as the leader who declares the loan interest rate or the EB platform's usage fee rate. From the equilibrium and coordinating analyses, we conclude that the active EB platform financing can achieve supply chain financing (SCF) coordination, yielding a larger order quantity and larger participants' profits than those yielded through BCF, while the conservative may not. When the coordination condition on order quantity is satisfied, if the initial working capital is a constant, there exists a linear decreasing trend between the EB platform's loan interest rate and the usage fee rate. When the weak coordination conditions are satisfied, the active EB platform can offer many coordinated financing contracts, which are applicable to different initial working capital conditions. For achieving SCF coordination, the EB platform should be active to adjust his loan interest rate and usage fee rate together. Moreover, even if the online retailer has sufficient working capital, she always prefers using the coordinated active EB platform financing to refusing any outside financing.
School Based Extremism and Drug Abuse Prevention in the UK
Venue: V International Forum on Teacher Education
Year: 2019

Young people and teenagers are the most vulnerable group for radical influences due to the fact that they are the most energetic and dynamic social group prone to social protest and high risk behaviors. Another risk factor for young people to become involved in extreme activities is drug addiction. Extremism and drug addiction have common ground. Being global in nature, both phenomena have destructive character and serious consequences for humankind. Terrorism acts regarded as a form of violent extremism are often carried out by aggressors being drunk or under the influence of psychoactive substances. Drugs are a part of extremist organizations which are often funded by financial resources obtained from drug trafficking. Based on the position that radicalization is a process and not a one time event, it is possible to intervene to prevent problems that may arise. Therefore seems appropriate for a specific provision of prevention initiatives to be included in the educational process. Since drug addiction is one of the risk factors for experimenting with extremism, it worth using a public health approach to counter the extremist ideology in a similar way to safeguarding processes to protect students from drug abuse. The study considers the UK's successful initiatives such as "From one extreme to another" "Getting Together" and "Channel" that target students and teachers in order to increase their awareness of the risks of extremism and prevent violence.
Tracking Meaning Change Over Time: A Dynamic Field Theory Model
Venue: CogSci
Year: 2017

Words are often regarded as "slippery customers" (Labov, 1973) First, it is difficult to come up with a fixed content that seems to apply across all uses of a single word (Wittgensten, 1953) Second, the meaning of a word is subject to wider contextual constraints beyond the company it keeps with other words within a sentence. Third, the assumption that a word means a fixed thing is at odds with the fact that word meaning shifts over time, as do the objects a word refers to. Taken together, theories of word meaning need to be able to account for the intuition that words have content associated with them, while allowing for variation in how a word is used in context, and how word meaning can change over time. We provide an approach to word meaning within the spirit of dynamic systems theory (DST) models of cognition that accounts for the slipperiness of words. First, we draw an analogy between models of (non linguistic) spatial behavior and how the meaning of language changes over time while exhibiting regularity. In particular, we identify two key features of DST models multicausality and the building of temporally bound attractor states that afford application to theories of meaning. Second, we take these features of DST models and test them in experiments examining the comprehension of spatial expressions over time using object placement behavior as a measure (e.g. "Place the oil paint tube over the toothbrush" Building on earlier work examining the constraints in which spatial language is used (Carlson Radvansky et al. 1999; Coventry, 2013, 2015; Coventry Garrod, 2004; Coventry et al. 2001, 2010, 2013, 2016; Gudde et al. 2016) we present a programme of studies mirroring early models of spatial memory, with experimental data showing striking similarity with results from other (non linguistic) spatial tasks (namely the A not B error tasks and associated model produced by Smith Thelen; e.g. Smith Thelen, 2003; Thelen et al. 2001) Third, we take these data, and show that a previous DST model originally developed to account for infant perseverative reaching behavior (Thelen et al. 2001) provides an elegant model of the changing meaning of spatial expressions over time.

A digital twin feasibility study (Part I) Non deterministic predictions of fatigue life in aluminum alloy 7075 T651 using a microstructure based multi scale model
Year: 2020

The Digital Twin (DT) concept has the potential to revolutionize the way systems and their components are designed, managed, maintained, and operated across a vast number of fields from engineering to healthcare. The focus of this work is the implementation of DT for the health management of fatigue critical structures. This paper is the first part of a two part series. The second part focuses on the use of in situ diagnostics to reduce uncertainty in fatigue life predictions once a life limiting fatigue crack has reached the point where it is observable. In contrast, the focus of this work is to form a non deterministic prediction of fatigue life prior to the accumulation of observable damage, a condition that often dominates the majority of a component or system's lifetime. This predictive capability is enabled by a DT framework that simulates crack growth from initiation to failure using microstructure based, multi scale modeling. Two models are used in this work, one that incorporates microstructure explicitly and one that uses more traditional linear elastic fracture mechanics. The models are joined by a transition crack length between the micro and macroscales, which facilitates both the coupling of fatigue life predictions and the transference of uncertainty across scales. The ability to predict fatigue life under uncertainty and across scales is demonstrated in the context of a geometrically complex, metallic test specimen subjected to uniaxial fatigue loading. Conclusions are drawn regarding the feasibility of the approach as a DT based health management method.
MANEJOS CLINICOS DA PSICOSE: O CASO ESTAMIRA NA VISAO PSICANALITICA E ANALITICA COMPORTAMENTAL
Year: 2017

A Psicose em contexto geral e definida como um estado mental patologico caracterizado pela perda de contato do individuo com a realidade, e tal quadro psiquico torna desafiador o trabalho terapeutico e consequentemente evidencia questionamentos quanto aos manejos e eficacia do tratamento. Desse modo, nesse trabalho analisou se o longa metragem Estamira baseado em duas diferentes abordagens tecnico teoricos da psicologia, a Analise do Comportamento e a Psicanalise, uma vez que ambas apresentam formas distintas de elaborar o seu trabalho. A partir de uma perspectiva comportamental, seria necessario compreender os comportamentos alucinatorios de Estamira pelo meio em que ela esta inserida, considerando as contingencias ambientais instaladoras e que mantem esses comportamentos, para assim serem desenvolvidas tecnicas visando a extincao desses sintomas. Na perspectiva psicanalista, busca se adentrar no universo em questao, utilizando se dos recursos linguisticos trazidos pela paciente, para promover aos poucos, a insercao de Estamira no mundo simbolico, a fim de estabelecer uma melhor qualidade de vida para si, e para sua relacao com o Outro. Conclui se que, embora os pressupostos das abordagens sejam muito distintos, o foco do tratamento e unico: promover uma melhor qualidade de vida do sujeito em questao, fazendo valer o rigor etico, tecnico, filosofico, teorico e pratico da profissao.  2006, v.8, n. 1, p.073 084, 2006.
