Relationship Between Problematic Use of Internet, Alexithymia and Family Dynamics:
Year: 2020

The study is an attempt to explore about the problematic usage of internet amongcollege students and its relation to alexithymia and family dynamics. The scientificreason for internet addiction is self indulgence due to stress and another reason is tocover up emotional and interpersonal problems. When troubled by stress, studentsmay engage in excessive use of internet. Self indulgent responses tend to be relativelyeasy to execute and highly pleasurable. It may eventually lead to internet addiction.There are many instances where people recognize that the young people ignore thecorrect emotional expressions while they interact with others. The reflectivebehaviours are essential for inter personal or family relationships. The reflectivebehaviour is learnt by observing behaviours of other and starts it from youngerdevelopmental stages. Due to using electronic gadgets for child engagement,insufficient inter personal interactions might be impaired and may lead to improperemotional development. If such conditions prevailed and sustained to higherdevelopmental stages, the conditions may be aggrieved. This condition will bedeveloped and considered as one of the reasons for alexithymia. The persons usingmore internets may have spent more time with electronic gadgets and may abstainfrom interpersonal interactions. It can be examined if explore the family relationships.The sample of the study consisted with 300 college students, studying in differentareas of knowledge in Kerala. The sample consisted the age group19 22 years. TheInternet Addiction Test, The Toronto Alexithymia Scale, and Family Dynamic Scalewere used to investigate the problem.
Acute toxicity of Ag and CuO nanoparticle suspensions against Daphnia magna: the importance of their dissolved fraction varying with preparation methods.
Venue: Journal of hazardous materials
Year: 2012

A variety of methods to prepare nanoparticle suspensions have been employed for aquatic toxicity tests, although they can influence the dispersion property and subsequent toxicity of nanoparticles. Thus, in this study, we prepared stock suspensions of silver (Ag) and copper oxide (CuO) nanoparticles using different methods and compared their acute toxicity against Daphnia magna. The results showed that the dispersion method, filtration and initial concentration largely affected their toxicity, when the toxicity was expressed as the total concentrations of Ag and Cu. In case of Ag nanoparticles, the toxicity was also influenced by their different particle size. However, negligible differences in 24h median effect concentration (EC(50) values, which were calculated in terms of their dissolved concentrations, were observed. When expressing toxicity on the basis of dissolved concentrations, 24h EC(50) values of the Ag and CuO nanoparticles were also found to be similar to those of the counterpart ionic species, i.e. Ag (as AgNO(3) and Cu (as CuCl(2)*2H(2)O) These findings indicate that the dissolved fraction of nanoparticles largely contributes to their acute toxicity. Our results may help in establishing a useful guideline for preparing nanoparticle suspensions with reproducible toxicity.

The Influence of Tumor Microenvironment on Immune Escape of Melanoma
Venue: International journal of molecular sciences
Year: 2020

The low efficiency of currently used anti cancer therapies poses a serious challenge, especially in the case of malignant melanoma, a cancer characterized by elevated invasiveness and relatively high mortality rate. The role of the tumor microenvironment in the progression of melanoma and its acquisition of resistance to treatment seems to be the main focus of recent studies. One of the factors that, in normal conditions, aids the organism in its fight against the cancer and, following the malignant transformation, adapts to facilitate the development of the tumor is the immune system. A variety of cell types, i.e. T and B lymphocytes, macrophages, and dendritic and natural killer cells, as well as neutrophils, support the growth and invasiveness of melanoma cells, utilizing a plethora of mechanisms, including secretion of pro inflammatory molecules, induction of inhibitory receptors expression, or depletion of essential nutrients. This review provides a comprehensive summary of the processes regulated by tumor associated cells that promote the immune escape of melanoma cells. The described mechanisms offer potential new targets for anti cancer treatment and should be further studied to improve currently employed therapies.
Novel association approach for variable number tandem repeats (VNTRs) identifies DOCK5 as a susceptibility gene for severe obesity.
Venue: Human molecular genetics
Year: 2012

Variable number tandem repeats (VNTRs) constitute a relatively under examined class of genomic variants in the context of complex disease because of their sequence complexity and the challenges in assaying them. Recent large scale genome wide copy number variant mapping and association efforts have highlighted the need for improved methodology for association studies using these complex polymorphisms. Here we describe the in depth investigation of a complex region on chromosome 8p21.2 encompassing the dedicator of cytokinesis 5 (DOCK5) gene. The region includes two VNTRs of complex sequence composition which flank a common 3975 bp deletion, all three of which were genotyped by polymerase chain reaction and fragment analysis in a total of 2744 subjects. We have developed a novel VNTR association method named VNTRtest, suitable for association analysis of multi allelic loci with binary and quantitative outcomes, and have used this approach to show significant association of the DOCK5 VNTRs with childhood and adult severe obesity (P(empirical) 8.9 x 10( 8) and P= 3.1 x 10( 3) respectively) which we estimate explains ~0.8% of the phenotypic variance. We also identified an independent association between the 3975 base pair (bp) deletion and obesity, explaining a further 0.46% of the variance (P(combined) 1.6 x 10( 3) Evidence for association between DOCK5 transcript levels and the 3975 bp deletion (P= 0.027) and both VNTRs (P(empirical) 0.015) was also identified in adipose tissue from a Swedish family sample, providing support for a functional effect of the DOCK5 deletion and VNTRs. These findings highlight the potential role of DOCK5 in human obesity and illustrate a novel approach for analysis of the contribution of VNTRs to disease susceptibility through association studies.
Bloom's taxonomy in software engineering education: A systematic mapping study
Venue: 2015 IEEE Frontiers in Education Conference (FIE)
Year: 2015

Designing and assessing learning outcomes could be a challenging activity for any Software Engineering (SE) educator. To support the process of designing and assessing SE courses, educators have been applied the cognitive domain of Bloom's taxonomy. However, to the best of our knowledge, the evidence on the usage of Bloom's taxonomy in SE higher education has not yet been systematically aggregated or reviewed. Therefore, in this paper we report the state of the art on the usage of Bloom's taxonomy in SE education, identified by conducted a systematic mapping study. As a result of the performed systematic mapping study, 26 studies were deemed as relevant. The main findings from these studies are: i) Bloom's taxonomy has mostly been applied at undergraduate level for both design and assessment of software engineering courses; ii) software construction is the leading SE subarea in which Bloom's taxonomy has been applied. The results clearly point out the usefulness of Bloom's taxonomy in the SE education context. We intend to use the results from this systematic mapping study to develop a set of guidelines to support the usage of Bloom's taxonomy cognitive levels to design and assess SE courses.

Venue: Proceedings of the International Conference on Auditory Display. International Conference on Auditory Display
Year: 2019

This study evaluated a web based auditory map prototype built utilizing conventions found in audio games and presents findings from a set of tasks participants performed with the prototype. The prototype allowed participants to use their own computer and screen reader, contrary to most studies, which restrict use to a single platform and a self voicing feature (providing a voice that talks by default) There were three major findings from the tasks: the interface was extremely easy to learn and navigate, participants all had unique navigational styles and preferred using their own screen reader, and participants needed user interface features that made it easier to understand and answer questions about spatial properties and relationships. Participants gave an average task load score of 39 from the NASA Task Load Index and gave a confidence level of 46/100 for actually using the prototype to physically navigate.
HafaNet: An Efficient Coarse to Fine Facial Landmark Detection Network
Venue: IEEE Access
Year: 2020

Facial landmark detection can be applied in various facial analysis tasks. It is a challenging problem due to the various poses and high real time requirements. To balance accuracy and computational efficiency, we propose an efficient coarse to fine network by combining heatmap regression and lightweight coordinate regression to detect facial landmarks. The heatmap regression network branch employs an efficient spatial pyramid and attention mechanism to regress to a better quality heatmap. The lightweight coordinate regression network branch introduces the local region perceptron to make the small network focus on the region of interest. Our method develops the advantages of heatmap regression and coordinate regression, which can improve landmark detection. Moreover, we propose a novel two stage FTS loss function that can further effectively solve the outlier problem in facial landmark detection. The comprehensive experiments demonstrate the effectiveness of our approach.

Production, activation, and applications of biochar in recent times
Venue: Biochar
Year: 2020

Biomass is a green energy source and is available in abundance. Biochar is a carbon rich material derived from a wide range of biomass or organic waste through the thermochemical route. Biochar has received increasing attention because of its distinctive properties such as high carbon content, greater specific surface area, cation exchange capacity, nutrient retention capacity, and stable structure. This review paper extensively studies and reports the different pyrolysis processes, reactor types, the effect of process parameters on biochar yield, and its physicochemical properties, biochar activation methods, and applications. It also details the status of the research and development (R&D) progress in biochar production through conventional and advanced technologies. The study found that unlike many products (at R&D stage) biochar has high potential to scale up and has a direct impact on crop yield, water purification (for domestic and industrial application) alternative fuels (clean solid fuel for cookstove) air purification, catalyst, biogas production, purification, and storage. In addition, the paper lists the merits and challenges in the novel biochar applications like hydrogen storage, electrochemical capacitor, and fuel cell technology.
A Spheroidal Model of Light Scattering by Nonspherical Particles
Venue: Optics and Spectroscopy
Year: 2019

We have constructed a spheroidal model to solve the problem of light scattering by nonspherical particles. The semiaxes of the model spheroid are determined based on the requirement that the volumes of initial and model particles are equal, as well as the ratios of their longitudinal and transverse dimensions. This ensures the closeness of the optical properties of initial and model particles. This approach has been applied to prolate and oblate parallelepipeds, cylinders, and cones with the ratios between their larger and smaller dimensions equal to 2 or 10. The direction of propagation of the incident TE or TM plane wave was either parallel or perpendicular to the symmetry axis of particles and model spheroid. The particle size has been determined by dimensionless parameter {x}_{{v} $2\pi {r}_{{v}/l, which depends on the particle volume, since {r}_{{v} is the radius of the equivolume sphere. In calculations, this parameter has been varied from small values to fairly large ones, {x}_{{v} 10. The applicability range of the model has been determined by comparing the results of numerical calculations performed by the rigorous separation of variables method for spheroids and the method of discrete dipoles for other nonspherical particles. It has been shown that the applicability range of the model for parallelepipeds, cylinders, and cones is wide enough for different parameters of the problem, in particular, if the parameter {x}_{{v} 6, then the relative error of the model does not exceed 10 15% To a large extent, this is related to the fact that the first maximum of the dependence of scattering factor Qsca on {x}_{{v} is similar for particles of different shapes approximated by one and the same model spheroid.
Export Upgrading and Economic Growth: a Panel Cointegration and Causality Analysis
Year: 2020

The main objective of this study is to examine the long run relationship between export upgrading and economic growth for 51 countries over the period of 1984 2015. For this purpose, a panel cointegration framework that allows to control for parameters heterogeneity, cross sectional dependence, and nonstationarity has been deployed. Furthermore, three homogenous subpanels have been considered based on the income level of the sample countries (high middle and low income subpanels) Empirical results from panel cointegration tests yield evidence of a long run relationship between export upgrading, economic growth, FDI, human capital, and trade openness. Moreover, based on the common correlated effects mean group (CCEMG) technique, the results indicate that export upgrading has a positive and significant effect on economic growth for the global, high income, and middle income panels, while this effect is insignificant for the low income country panel. The causality analysis indicates the existence of a feedback effect between export complexity and economic growth for the global panel as well as for the high and middle income country groups in the long run. For low income countries, however, there is no causal relationship between these two variables, and this finding holds both in the short run and in the long run.

Drivers and mechanisms of tree mortality in moist tropical forests.
Venue: The New phytologist
Year: 2018

Tree mortality rates appear to be increasing in moist tropical forests (MTFs) with significant carbon cycle consequences. Here, we review the state of knowledge regarding MTF tree mortality, create a conceptual framework with testable hypotheses regarding the drivers, mechanisms and interactions that may underlie increasing MTF mortality rates, and identify the next steps for improved understanding and reduced prediction. Increasing mortality rates are associated with rising temperature and vapor pressure deficit, liana abundance, drought, wind events, fire and, possibly, CO2 fertilization induced increases in stand thinning or acceleration of trees reaching larger, more vulnerable heights. The majority of these mortality drivers may kill trees in part through carbon starvation and hydraulic failure. The relative importance of each driver is unknown. High species diversity may buffer MTFs against large scale mortality events, but recent and expected trends in mortality drivers give reason for concern regarding increasing mortality within MTFs. Models of tropical tree mortality are advancing the representation of hydraulics, carbon and demography, but require more empirical knowledge regarding the most common drivers and their subsequent mechanisms. We outline critical datasets and model developments required to test hypotheses regarding the underlying causes of increasing MTF mortality rates, and improve prediction of future mortality under climate change.
Design of Highly Efficient CZTS/CZTSe Tandem Solar Cells
Venue: Journal of Electronic Materials
Year: 2020

A CZTS/CZTSe tandem solar cell with copper zinc tin sulfide (CZTS) and copper zinc tin selenide (CZTSe) absorber layers for the top and bottom cell, respectively, is proposed. The effects of different interconnect layers such as graphene, fluorine doped tin oxide (FTO) indium tin oxide (ITO) and a p n tunnel junction consisting of CZTS and CdS on the performance of the cell are investigated, revealing that the p n tunnel junction results in the best performance. The impact of adding a thin SnS layer under the absorber layers to reduce recombination is also examined, revealing a significant improvement in cell performance. The optimized thicknesses of the buffer and absorber layers are obtained in all cases. The maximum efficiency of 26.21% is achieved in the optimum tandem device including the SnS layer and p n tunnel junction, being much higher than results for previous structures. Finally, the effect of the absorber bandgap energy on the performance of the tandem cells is investigated.
Pulmonary Nodule Detection Based on Convolutional Block Attention Module
Venue: 2019 Chinese Control Conference (CCC)
Year: 2019

Since the diagnosis of lung cancer requires a careful investigation of each suspicious nodule, traditional detection approaches need to integrate the information of all nodules. In deep learning, the convolutional block attention module can be integrated into convolutional neural network architectures for adaptive feature refinement. Therefore, we propose a state of the art pulmonary detection network, which embeds this attention module. Furthermore, the bounding box regression is redefined to enhance convergence ability. The novel detection network is validated on a public dataset from LUNA16, which achieves 0.854 sensitivity rate.
Impact of Proactive Postsales Service and Cross Selling Activities on Customer Churn and Service Calls
Venue: Journal of Service Research
Year: 2019

In recent years, service providers have identified the proactive postsales service (PPS) as a viable measure for preempting service failures and their negative consequences. Due to the high costs associated with PPSs, companies are looking for ways to increase their efficiency. To understand how companies can increase their revenues and lower their costs, this study investigates how cross selling activities and different media types affect the impact of a PPS on inbound service calls and customer churn. Based on a large scale field experiment in the telecommunications industry, as well as a controlled lab experiment, the results demonstrate the overall effectiveness of the PPS and indicate two mediating effects. While the effect of cross selling on customer churn and service calls is mediated by the customers' uncertainty regarding the company's motives, it is the customers' perception of privacy invasion that mediates the influence of the contact medium on the effectiveness of the PPS. Our finding that PPS contacts have to be clear in their message and should not be perceived as invasive is an indication of the importance of service (post)sales ambidexterity.
