Motivators of online vulnerability: The impact of social network site use and FOMO
Venue: Comput. Hum. Behav.
Year: 2017

Continued and frequent use of social network sites (SNS) has been linked to a fear of missing out (FOMO) and online self promotion in the form of friending and information disclosure. The present paper reports findings from 506 UK based Facebook users (53% male) who responded to an extensive online survey about their SNS behaviours and online vulnerability. Structural equation modelling (SEM) suggests that FOMO mediates the relationship between increased SNS use and decreased self esteem. Self promoting SNS behaviours provide more complex mediated associations. Longitudinal support N 175) is provided for the notion that decreased self esteem might motivate a potentially detrimental cycle of FOMO inspired online SNS use. The research considers the implications of social networking on an individual's online vulnerability.
The Use of Hinged Craniotomy in Comparison to Cisternostomy for Avoiding Bone Flap Replacement Second Surgery in Cases of Decompressive Craniotomy in Traumatic Brain Injury
Year: 2019

Acute post traumatic subdural hematoma is a clinical condition with increased morbidity and mortality despite the developments in neurosurgery and urgent intervention is required to have best clinical outcome. We will evaluate hinged craniotomy technique in terms of offering adequate brain decompression plus avoiding removal of bone flap which requires second replacement surgery in comparison to cisternostomy effect.  A prospective study was conducted over 30 patients with traumatic acute subdural hematoma presented to neurotrauma unit in Cairo University hospitals from January 2017 to February 2018, operated by hinged craniotomy plus evacuation of hematoma and duroplasty. We avoid rapping the head with elastic bandage post operative. Generous subcutaneous dissection (5 7 cm) all around skin flap was done routinely. Effect of brain decompression was evaluated by measuring the level of brain in relation to skull in post operative computerized topography.  Twenty one patients operated with initial GCS less than eight. Ten cases (33% show that cortical surface in relation to skull bone was at inner table, nine cases (30% at diploid layer and two cases (6.7% at outer table in post operative CT brain. Twenty patients died (66.7% eight patients (26.6% became fully conscious and two patients (6.7% had vegetative outcome. No re operation was done in any of our patients.  Hinged craniotomy may be a safe and effective alternative technique with comparable results to cisternotomy in cases of traumatic brain injury that require decompression to avoid second surgery, especially in centres lacking cisternostomy experience. Although gaining cisternostomy experience may help in other indications, future prospective studies with larger number are required.
Generation Z consumers' expectations of interactions in smart retailing: A future agenda
Venue: Comput. Hum. Behav.
Year: 2017

Retailing is witnessing a transformation due to rapid technological developments. Retailers are using smart technologies to improve consumer shopping experiences and to stay competitive. The biggest future challenge for marketing and consequently for retailing seems to be generation Z, since members of this generation seem to behave differently as consumers and are more focused on innovation. The aim of this paper is to explore Generation Z consumers' current perceptions, expectations and recommendations in terms of their future interactions in smart retailing contexts. To do so, we used a qualitative approach by conducting a series of semi structured in depth interviews with 38 university students consumers in the UK market. The findings showed that smart technologies have a significant influence on generation Z consumers' experiences. Moreover, this particular group of consumers expects various new devices and electronic processes to be widely available, thus offering consumers more autonomy and faster transactions. In addition, they expect the technology to enable them to make more informed shopping decisions. Interviewees also stressed the importance of training consumers how to use new smart retailing applications. In addition, some of the participants were sceptical about the effects of further advancing smart retailing on part of the job market. Relevant theoretical and practical implications are also provided. Exploration of Generation Z consumers' expectations of interactions in the smart retailing setting.The introduction of more new devices and processes is expected.Training consumers about new smart retailing applications is essential.There is scepticism about further advances in smart retailing in relation to job market.
Investigations of the Performance on Vaned Diffusers for Low Specific Speed Centrifugal Compressor
Year: 2014

In this paper, the performance of vaned diffusers on low specific speed centrifugal compressors, was investigated experimentally and analytically. There is a problem of non uniform distribution of the flow at impeller exit, as a factor to deteriorate the performance of the diffuser. This problem appears remarkably on the low specific speed type, because the blade height is relatively small and the flow inclines toward circumferential direction. The experiment was carried out with 2nd stage compressor of two stage centrifugal type, focusing on the effect of number of diffuser vanes, vaneless ratio and throat area. Furthermore, unsteady fluid analysis was carried out by using Non Linear Harmonic method in order to understand about the phenomenon associated with the problem of non uniform distribution of the flow.

An evolving spatio temporal approach for gender and age group classification with Spiking Neural Networks
Venue: Evol. Syst.
Year: 2018

This research study proposes a novel method of inter related problems in face recognition using the NeuCube neuromorphic computational platform. We investigated age classification and gender recognition. The well known FG NET and MORPH Album 2 image gallery were used and anthropometric features were extracted from landmark points on the face. The landmarks were pre processed with the procrustes algorithm before feature extraction was performed. The Weka machine learning workbench was used to compare the performance of traditional techniques such as the K nearest neighbor (Knn) and Multi LayerPerceptron (MLP) with NeuCube. Our empirical results show that NeuCube performed consistently better across both problem types that we investigated.
Sentence Simplification with Transformer XL and Paraphrase Rules
Year: 2019

Neural sentence simplification is an emerging technology which aims to automatically simplify a sentence with complex syntax and/or diction while preserving its meaning. Most of the existing work on neural sentence simplification has modeled the task as monolingual machine translation (MT) and has investigated applications of architectures such as RNNor Transformer based seq2seq encoder decoder networks. In this project, we explore a new model by adapting Transformer XL, the cutting edge architecture for language modeling (LM) to sentence simplification. In addition, we propose and investigate two original approaches to incorporate the Simple Paraphrase Database (PPDB) a large database of reduction rules for words and phrases. The character level Transformer XL model achieved performance close to SOTA. Though our experiments using the SimplePPDB variants do not achieve desirable results, they reveal important insight regarding the integration of accurate paraphrase rules into neural models. This project is the first known application of Transformer XL to a non LM task, as well as the first known sentence simplification model that can use character embeddings.
Cognitive test anxiety scale: Propriedades psicometricas no contexto brasileiro
Year: 2020

Cognitive anxiety refers to excessive worries before, during and after of the tests, interfering in the performance and causing academic failure, and is positively associated with neuroticism and depression.  The objective was to gather evidence of psychometric quality of the Cognitive Test Anxiety Scale (CTAS) in Brazil.  Two studies were conducted: In study 1, 210 university students from the city of Parnaiba, Piaui, Brazil (Average age 21.7; SD 3.73) participated, most of them studying Psychology (60% and women (58.6% They answered CTAS and demographic questions. An exploratory factor analysis suggested a one dimensional solution that explained 46.94% of the total variance of the items. Reliability was evaluated by Cronbach's alpha and McDonald's omega indicators equal to .92. In Study 2, 274 university students from different Brazilian regions participated (Average age 21.7; SD 3.73) most of the state of Piaui (60% studying Psychology (60.4% A confirmatory factor analysis indicated adequate indicators (CFI .96; TLI .95; RMSEA .06) The reliability was satisfactory: and equal to .94.  Psychometric evidence was found for Brazil, and CTAS may be useful for those interested in investigating the theme and its correlates.
Evaluation des risques allergeniques pour les aliments genetiquement modifies d'origine vegetale
Year: 2017

Resume La propagation rapide des produits agro biotechnologiques a suscite beaucoup de controverses au sujet des avantages, des risques et des limites des plantes transgeniques. Les effets nefastes des plantes genetiquement modifiees (GM) qui peuvent etre ingerees peuvent provoquer des effets toxiques ou l'induction de reponses immunitaires indesirables, telles qu'une activite de modulation allergique ou immunitaire. L'evaluation de l'allergenicite est une etape dans l'evaluation de la biosecurite des aliments derives de cultures GM. Cet article de revue se concentre sur un sujet d'interet courant, l'analyse du potentiel allergenique des aliments derives de cultures genetiquement modifiees, des strategies d'evaluation institutionnelle, des techniques proteomiques pour l'identification de proteines transgeniques ayant des proprietes allergeniques. Des etudes recentes montrent l'impact des cultures transgeniques du ble (albumine/globuline et gluten) sur l'asthme et l'allergie alimentaire IgE dependante. Par consequent, une analyse complete des allergenes (allergenomique) est tres importante pour l'evaluation des risques non seulement des plantes alimentaires, mais aussi pour le diagnostic des symptomes allergiques.
Time Dependent Policy Based Access Control
Venue: TIME
Year: 2017

Access control policies are essential to determine who is allowed to access data in a system without compromising the data's security. However, applications inside a distributed environment may require those policies to be dependent on the actual content of the data, the flow of information, while also on other attributes of the environment such as the time. In this paper, we use systems of Timed Automata to model distributed systems and we present a logic in which one can express time dependent policies for access control. We show how a fragment of our logic can be reduced to a logic that current model checkers for Timed Automata such as UPPAAL can handle and we present a translator that performs this reduction. We then use our translator and UPPAAL to enforce time dependent policy based access control on an example application from the aerospace industry.
Crystal structures and atomic model of NADPH oxidase
Venue: Proceedings of the National Academy of Sciences
Year: 2017

Reactive oxygen species (ROS) are far from being only an inevitable byproduct of respiration. They are instead actively generated by NADPH oxidases (NOXs) a family of highly regulated enzymes that underpin complex functions in the control of cell proliferation and antibacterial defense. By investigating the individual catalytic domains, we elucidate the core of the NOX 3D structure. An array of cofactors is spatially organized to transfer reducing electrons from the intracellular milieu to the ROS generating site, exposed to the outer side of the cell membrane. This redox chain is finely tuned by structural elements that cooperate to control NADPH binding, thereby preventing noxious spills of ROS. Our findings indicate avenues for the pharmacological manipulation of NOX activity. NADPH oxidases (NOXs) are the only enzymes exclusively dedicated to reactive oxygen species (ROS) generation. Dysregulation of these polytopic membrane proteins impacts the redox signaling cascades that control cell proliferation and death. We describe the atomic crystal structures of the catalytic flavin adenine dinucleotide (FAD) and heme binding domains of Cylindrospermum stagnale NOX5. The two domains form the core subunit that is common to all seven members of the NOX family. The domain structures were then docked in silico to provide a generic model for the NOX family. A linear arrangement of cofactors (NADPH, FAD, and two membrane embedded heme moieties) injects electrons from the intracellular side across the membrane to a specific oxygen binding cavity on the extracytoplasmic side. The overall spatial organization of critical interactions is revealed between the intracellular loops on the transmembrane domain and the NADPH oxidizing dehydrogenase domain. In particular, the C terminus functions as a toggle switch, which affects access of the NADPH substrate to the enzyme. The essence of this mechanistic model is that the regulatory cues conformationally gate NADPH binding, implicitly providing a handle for activating/deactivating the very first step in the redox chain. Such insight provides a framework to the discovery of much needed drugs that selectively target the distinct members of the NOX family and interfere with ROS signaling.
A Cross sectional Analysis of Adverse Events and Litigation for Injectable Fillers
Venue: JAMA facial plastic surgery
Year: 2018

Importance Injectable fillers are increasing in popularity as a noninvasive option to address concerns related to facial aging and volume loss. To our knowledge, there have been no large scale analyses of adverse events and associated litigation related to filler injections.  To determine risks of injectable fillers and analyze factors raised in litigation related to injectable fillers.  In this cross sectional review, the US Food and Drug Administration's (FDA) manufacturer and user facility device experience (MAUDE) database was evaluated for complications from the use of the following fillers: Juvederm, Restylane, Belotero, Sculptra, Radiesse, Artefill, Bellafill, and Juvederm Voluma from 2014 to 2016. The Westlaw Next database was used to identify jury verdicts.  Complications were organized by type of filler used, location of injection, and severity. Intra arterial injections without sequelae and those resulting in blindness or necrosis were considered severe complications. Factors raised during the litigation process were also analyzed.  Of 1748 adverse events analyzed, most cases stemmed from cheek (751 [43.0% or lip (524 [30.0% injection. Commonly reported adverse events reported included swelling (755 [43.2% and infection (725 [41.5% Among FDA reported complications, blindness was significantly associated with dorsal nasal injections (P .001) Vascular compromise with and without sequela of dermal necrosis and blindness were significantly associated with Radiesse injections P .001. Of the 9 malpractice cases identified, two thirds involved allegations of inadequate informed consent, and the median award in cases resolved with payment was $262 000.  Although specific complication profiles vary by material and injection site, common adverse events associated with injectable fillers include swelling and infection. More serious events include vascular compromise, resulting in necrosis and blindness; these events are also raised in cases involving litigation. This analysis illustrates the importance of outlining these risks in a comprehensive preoperative informed consent process.

Creative metaphor production in a first and second language and the role of creativity
Year: 2018

The study of metaphor is an interdisciplinary endeavor crossing such fields as cognitive linguistics, psychology, and creativity studies. Two important conclusions on the nature of metaphor have been drawn to date: (1) the ability to use metaphor is a normal human cognitive ability and widespread in language; (2) metaphor is not a unitary construct and varies greatly from the highly familiar and conventional to the creative. Viewing metaphor as lying along a continuum, this thesis narrows the concept of metaphoric competence to creative metaphoric competence, which looks at this ability from a creativity perspective. In this thesis, it is hypothesized that creative metaphoric competence is an underlying competency, which is related to a more general creative competence, and therefore is projected onto both the L1 (Japanese) and L2 (English) In order to test this hypothesis, data from creative metaphor production tasks were collected in both languages. In addition, a number of creativity measurements were also developed with the aim of measuring the multifaceted nature of creativity. Relationships between these variables were investigated. Findings suggest that creative metaphoric competence is an individual difference variable, which could be described as a disposition towards novelty and is related to other measurements of creativity.
Radiocarbon Dating of Legacy Music Instrument Collections: Example of Traditional Indian Vina from the Musee De La Musique, Paris
Venue: Radiocarbon
Year: 2019

Although radiocarbon (14C) dating is commonly used for archeological music instruments, little research has been conducted on modern instruments (16th 19th centuries) New technology, based on the Mini Carbon Dating System (MICADAS) enables some of the recurring challenges (e.g. sampling size) to be circumvented and paves the way for a new field of investigation. We here address the Indian instrumentarium, about which very little is known. We investigate the making and the restoration phases of two vina, a kinnari vina (E.1444) and a rudra vina or bin (E.997.24.1) By comparing 14C measurements made on several samplings of elements of the instruments with museological information, we were able to specify a unique calibrated interval of ages [1666 AD 1690 AD] for the kinnari vina, with a restoration phase [1678 AD 1766 AD] for the upper nut. The bin is likely attributed to the [1650 AD 1683 AD] interval.
Anthropomorphic Prosthetic Hand with Combination of Light Weight and Diversiform Motions
Venue: Applied Sciences
Year: 2019

Most prosthetic hands adopt an under actuated mechanism to achieve dexterous motion performance with a lightweight and anthropomorphic design. Many have been verified in laboratories, and some have already been commercialized. However, a trade off exists between the dexterity and the light weight of such prosthetic hands. In general, current commercially available prosthetic hands usually consider one aspect at the expense of the other, such as obtaining diversiform hand motions but an increased weight, or achieving lightweight design but with limited motion functions. This study attempts to attain a balance between the two factors, by realizing diversiform hand motions while reducing the weight as far as possible. An anthropomorphic prosthetic hand is proposed with only three servomotors embedded in a human sized palm, with multiple functions, such as a stable/adaptive grasp and passive hyperextension. The proposed hand can achieve 13 grasp types with over 80% of the grasp motions under the Cutkosky taxonomy, while it weighs only 132.5 g, at less than 36% of the prosthesis weight limitation based on the study of Kay et al.
Frantisek X. Halas on T. G. Masaryk's Relationship to the Roman Catholic Church
Year: 2018

Frantisek X. Halas in his historical work was also concerned with the person of T. G. Masaryk, in particular in his most extensive publication The Phenomenon of the Vatican. It analyses the struggle over the sense of Czech history between Masaryk and Pekar and explores in general Masaryk's views on the religious question. The greatest attention is paid to Masaryk's views of the Roman Catholic Church, both before the World War as well in the foreign resistance even at the time of his time in office as President. His interpretation of Masaryk's views is objective and understandably critical in a number of cases. It describes very well the reasons behind Masaryk's particular positions.
