Addiction to Video Games: A Case Study on the Effectiveness of Psychodynamic Psychotherapy on a Teenage Addict Struggling with Low Self Esteem and Aggression Issues
Year: 2018

The present case study focused on a 14 years old teenager who struggled with addiction to computer games and subsequent issues of aggression and social withdrawal. Drawing from theories on addiction, self esteem, and mentalization, we focused the connection of addiction to low self esteem and poor mental representations. In addition, we examined the effectiveness of psychodynamic psychotherapy on treating addiction improving levels of self esteem and alleviating aggressive behaviour over a course of two and a half years. Indeed, the use of a combination of three projective tests, namely the Thematic Apperception Test, the Kinetic Family Drawing, the Family Apperception Test and the Rosenberg Self Esteem Scale helped us determine our patient's emotional state and lack of self esteem at the beginning of therapy. The same tests were administered at the end of the therapeutic sessions and the results are discussed in relation to the progress of the patient over the course of the therapy.
Effects of extracts of Daucus carota and Brassica oleraceae on ethanol induced gastric ulcer
Year: 2019

Disruption of gastric mucosal integrity occurs due to imbalance between defensive and offensive factors. This requires treatment using pharmacological agents to reduce the burden. The associated drug adverse effects attract research into crude plant materials and plant products from which active compounds with promising therapeutic results can be obtained. Phytochemical screening of D. carota and B. oleraceae extract were done. Forty eight Wistar strain rats, age 8 10 weeks, weighing 100g 152g, were acclimatized for 14 days after which they were fasted for 10 12h and given 1ml of 90% ethanol/100g body weight orally to induce gastric ulceration. Extract of D. carota and B. oleraceae were administered orally for fifteen days after which the rats were sacrificed and stomach harvested. Phytochemical screening showed that both D. carota and B. oleraceae contain tannin, cardiac glycoside. Stomach tissue antioxidant levels showed a non significant increase in GSH (p 0.21) a significant increase in SOD and CAT (p 0.000, 0.000) and a significant decrease in MDA, GPx, and GPR (p 0.000, 0.002, 0.000) in the treated groups. B. oleraceae extract demonstrated a 25.7% cure, D. carota extract showed 56.6% cure while combined B. oleraceae and D. carota extracts showed 70% cure rate. Modifications of gastric mucosal damage by the administered extracts were revealed histopathologically. It could be concluded that extract of D. carota and B. oleraceae singly or in combination exhibited antiulcer activities in ethanol induced gastric ulceration and showed some synergism in the management of gastric ulcer.

Simulation of Heat Loss in CZTSSe Thin Film Solar Cells: A Coupled Optical Electrical Thermal Modeling
Year: 2021

A coupled optical electrical thermal modeling has been developed to investigate the heat generation in CZTSSe solar cells via Thermalization, Joule heat, Peltier heat, Surface Recombination heat, and non radiative recombination heat and also the heat dissipation via convective and radiative cooling. These were calculated and displayed in 2D and 3D maps either at zero bias or open circuit voltage (V oc) conditions. At V=0, the heat is generated mainly at the junction of CZTSSe/CdS where the thermalization and Joule heats are dominantly higher compared to non radiative (SRH and Auger) recombination heat. However, at V=V oc the nan radiative recombination heat becomes comparatively higher than the Joule heating whereas the thermalization remains highest as before. Apart from the bulk heating factors, we also studied the surface recombination and Peltier heat generation. The surface recombination heat is higher at V=V oc compared to at V=0 while the Peltier heat is zero at V=V oc which can be explained by looking at the energy band diagrams at these voltages. The total heat generation does not change much across the cell thickness <5x10 9 W/m 3) as the cell is quite thin. Nevertheless, the individual impact of every heat generation factor on power density and current voltage characteristics of the cell reveals that the thermalization, Joule, and non radiative recombination heats reduce the open circuit voltage of the cell from 0.54 V to 0.49 V (V 0.047 V) while the Peltier and surface recombination heat is less effective. The temperature of the cell shows a small distribution across the cell (0.01 K) However, the temperature of the initial study at 293 K increases to 315 320 K for the coupled study. At this increased temperature, the short current density doesn't change but the fill factor decreases from 73.8% to 71.8% and, therefore, the energy conversion efficiency of the cell falls by 11.11% (from initial 12.78% to 11.36% All the total heat dissipation, convective, and radiation cooling follow a similar trend to the total heat generation but convective cooling is the dominant component of dissipation.

A Probabilistic Framework for Constrained Manipulations and Task and Motion Planning under Uncertainty
Venue: 2020 IEEE International Conference on Robotics and Automation (ICRA)
Year: 2020

Logic Geometric Programming (LGP) is a powerful motion and manipulation planning framework, which represents hierarchical structure using logic rules that describe discrete aspects of problems, e.g. touch, grasp, hit, or push, and solves the resulting smooth trajectory optimization. The expressive power of logic allows LGP for handling complex, large scale sequential manipulation and tool use planning problems. In this paper, we extend the LGP formulation to stochastic domains. Based on the control inference duality, we interpret LGP in a stochastic domain as fitting a mixture of Gaussians to the posterior path distribution, where each logic pro le defines a single Gaussian path distribution. The proposed framework enables a robot to prioritize various interaction modes and to acquire interesting behaviors such as contact exploitation for uncertainty reduction, eventually providing a composite control scheme that is reactive to disturbance.
Inside the Loop: The Audio Functionality of Inside
Venue: The Computer Games Journal
Year: 2018

The manner in which soundscapes evolve and change during gameplay can have many implications regarding player experience. INSIDE (Playdead in INSIDE. Released on Microsoft Windows, Playstation 4, Xbox One, Nintendo Switch and iOS, 2016) features a gameplay section in which rhythmic audio cues loop continuously both during gameplay and after player death. This paper uses this aspect of the soundtrack as a case study, examining the effects of looping sound effects and abstract musical cues on player immersion, ludic functionality, and episodic engagement. The concept of spectromorphology proposed by Smalley (Organised Sound 2(2):107 126, 1997) is used to analyse the way in which musical cues can retain ludic functionality and promote immersion in the absence of diegetic sound design. The "musical suture" (Kamp,  Ludomusicology: approaches to video game music, Equinox, Sheffield, 2016) created by continuously looping audio during death and respawn is also examined with regards to immersing the player within an evolving soundscape.

Independent component analysis of short time Fourier transforms for spontaneous EEG/MEG analysis
Venue: NeuroImage
Year: 2010

Analysis of spontaneous EEG/MEG needs unsupervised learning methods. While independent component analysis (ICA) has been successfully applied on spontaneous fMRI, it seems to be too sensitive to technical artifacts in EEG/MEG. We propose to apply ICA on short time Fourier transforms of EEG/MEG signals, in order to find more "interesting" sources than with time domain ICA, and to more meaningfully sort the obtained components. The method is especially useful for finding sources of rhythmic activity. Furthermore, we propose to use a complex mixing matrix to model sources which are spatially extended and have different phases in different EEG/MEG channels. Simulations with artificial data and experiments on resting state MEG demonstrate the utility of the method.

Anti inflammatory Effect of Ghrelin in Lymphoblastoid Cell Lines From Children With Autism Spectrum Disorder
Venue: Front. Psychiatry
Year: 2019

The gut hormone ghrelin has been implicated in a variety of functional roles in the central nervous system through the brain gut axis, one of which is an anti inflammatory effect. An aberrant brain gut axis producing immune dysfunction has been implicated in the pathobiology of autism spectrum disorder (ASD) and elevated expression of inflammatory markers has been shown in blood and brain tissue from subjects with ASD. We hypothesized that ghrelin may mitigate this effect. Lymphoblastoid cell lines from typically developed children (TD C) (N 20) and children with ASD (ASD C) (N 20) were cultured with PBS or human ghrelin (0.01 mM) for 24 h, and mRNA expression levels of the inflammation related molecules interleukin 1b (IL 1b) interleukin 6 (IL 6) tumor necrosis factor a (TNF a) and nuclear factor kappa B (NF kB) were measured to examine the effects of ghrelin as an anti inflammatory agent. Expression levels of TNF a and NF kB mRNA, but not IL 1b or IL 6, were significantly elevated in ASD C compared to TD C. Ghrelin showed a tendency to reduce the expression of TNF a and NF kB, but this was not statistically significant. Considering the heterogenous pathobiology of ASD, we examined the effects of ghrelin on TD C and ASD C with expression levels of TNF a and NF kB in the highest and lowest quartiles. We found that ghrelin markedly reduced mRNA expression of TNF a and NF kB s in ASD C with highest quartile expression, but there were no effects in ASD C with lowest quartile expression, TD C with highest quartile expression, or TD C with lowest quartile expression. Together, these findings suggest that ghrelin has potential as a novel therapeutic agent for ASD with inflammation and/or immune dysfunction.
Wild edible plants: sustainable use and management by indigenous communities in and the buffer area of Awash National Park, Ethiopia
Year: 2013

Wild edible plants are valuable resources in rural livelihoods for supplementing the staple food, ensuring food security, dietary diversification and sustained income. This study aimed to identify and document indigenous uses and management of wild edible plants being used by the Afar and Oromo communities in and the buffer area of Awash National Park. A total of 96 informants between the ages of 20 and 80 were identified using prior information. Data were collected using semi structured interviews, guided field walk, discussions, market surveys and field observation. A total of 55 wild edible species were identified by members of the local communities. About 93% of the species were reported with their vernacular (local) names, where 69% were reported by the Afar and 87% by the Oromo communities. Eighty nine percent of the species were classified as indigenous to the area, while 11% were classified as exotics. P reference ranking indicated that the fruits of Balanites aegyptiaca (L. Del. are the most preferred edible fruit by the local communities. The local people access the National Park for some of the wild edible plants as they are largely depleted from the surrounding areas. The yet untapped potentials of the wild edible plants as food sources in the area need better attention in future research plans. The issue of conservation of wild edible plants is unquestionable to ensure household food security, dietary diversification and local communities' income, which also contributes to the biodiversity
Decentralized Transmission Line Switching for Congestion Management of Interconnected Power Systems
Venue: IEEE Transactions on Power Systems
Year: 2018

Independent system operators (ISOs) are responsible for the secure and economic operation of the power systems. Accordingly, ISOs should solve an optimal power flow to minimize the operating cost of a system while meeting the system's security constraints. However, transmission congestion could drastically limit more economical generating units from being dispatched in the power system operation. In this paper, a decentralized transmission switching is introduced in the operation of multi area power systems to manage the congestion both on regional transmission lines and tie lines while considering credible contingencies. Our proposed methodology relies on a decentralized optimization methodology. Thus, regional control centers in areas would be able to locally manage the congestion within their regional networks as well as tie lines connecting them to their neighboring areas. Several testing systems are studied in this paper to test the effectiveness of the proposed method.
Early development of letter specialization in left fusiform is associated with better word reading and smaller fusiform face area.
Venue: Developmental science
Year: 2018

A functional region of left fusiform gyrus termed "the visual word form area" (VWFA) develops during reading acquisition to respond more strongly to printed words than to other visual stimuli. Here, we examined responses to letters among 5 and 6 year old early kindergarten children (N 48) with little or no school based reading instruction who varied in their reading ability. We used functional magnetic resonance imaging (fMRI) to measure responses to individual letters, false fonts, and faces in left and right fusiform gyri. We then evaluated whether signal change and size (spatial extent) of letter sensitive cortex (greater activation for letters versus faces) and letter specific cortex (greater activation for letters versus false fonts) in these regions related to (a) standardized measures of word reading ability and (b) signal change and size of face sensitive cortex (fusiform face area or FFA; greater activation for faces versus letters) Greater letter specificity, but not letter sensitivity, in left fusiform gyrus correlated positively with word reading scores. Across children, in the left fusiform gyrus, greater size of letter sensitive cortex correlated with lesser size of FFA. These findings are the first to suggest that in beginning readers, development of letter responsivity in left fusiform cortex is associated with both better reading ability and also a reduction of the size of left FFA that may result in right hemisphere dominance for face perception.
Mining Synchronous and Asynchronous Co Regulated Gene Clusters from Time Series Microarray Data
Year: 2007

Gene co regulation falls into two major categories, i.e. synchronous and asynchoronous co regulation. This paper proposes a new model Reg Cluster, which groups synchronous and asynchoronous co regulated genes together if they have the same code. Further, an effective clustering algorithm with several efficient pruning rules, namely FBLD, is designed to identify all maximal Reg Clusters in a "First Breadth first and Last Depth first" manner. The resultant clusters contain the detailed and complete co regulation information, which facilitates the study of genetic regulatory networks. Moreover, the method can be extended to the analysis of 3D gene sample time microarray data. The FBLD algorithm has been implemented on both real and synthetic datasets and the results from the real dataset has been submitted to Gene Ontology. Experimental results prove the effectiveness and efficiency of the proposed method.
