COVID-19 and Its Triangle Effects on Human's Well-Being: a Qualitative Research Method Used to Collect Appropriate Data.
2021
Background: The health-related challenges caused by the virus and the implications of the policies implemented to fight against it further cause psychological and socio-economic consequences that could threaten the well-being of the people. Objective: This study has been carried out to identify people's psychosoical reactions toward COVID-19. Method: Semi-structured interviews as a qualitative research method were used to collect data from 20 people across three countries, and content analysis was applied to interpret the data. Results: Overall, the results indicated that COVID-19 has had negative consequences on psychological well-being of the general population. COVID-19 has forced people…
Opinion dynamics and stubbornness through mean-field games
2013
This paper provides a mean field game theoretic interpretation of opinion dynamics and stubbornness. The model describes a crowd-seeking homogeneous population of agents, under the influence of one stubborn agent. The game takes on the form of two partial differential equations, the Hamilton-Jacobi-Bellman equation and the Kolmogorov-Fokker-Planck equation for the individual optimal response and the population evolution, respectively. For the game of interest, we establish a mean field equilibrium where all agents reach epsilon-consensus in a neighborhood of the stubborn agent's opinion.
Smartphone data analysis for human activity recognition
2017
In recent years, the percentage of the population owning a smartphone has increased significantly. These devices provide the user with more and more functions, so that anyone is encouraged to carry one during the day, implicitly producing that can be analysed to infer knowledge of the userâs context. In this work we present a novel framework for Human Activity Recognition (HAR) using smartphone data captured by means of embedded triaxial accelerometer and gyroscope sensors. Some statistics over the captured sensor data are computed to model each activity, then real-time classification is performed by means of an efficient supervised learning technique. The system we propose also adopts a …
An Adapted Gating Strategy Integrating a Myelomonocytic Window Is Necessary For Correct Flow Cytometric Diagnosis In a Large Proportion Of AML With M…
2013
Abstract Background Previously, it has been reported, that AML with mutated NPM1 is associated with a distinctive immunophenotype. In particular, low or absent expression of CD34 accompanied by high expression of CD33, and – at least in part of the cases - absence of HLA-DR expression was reported. CD45/side scatter (SSC) gating is widely used for the identification of blasts by flow cytometry (FC). Blast cell gates typically are defined by a low SSC and moderate CD45 expression. However, in a number of patients with NPM1mutation this typical blast cell gate comprises significantly lower blast percentages when compared to the morphological evaluation. In these patient samples a second popul…
Prevalence of lip lesions in an Indian population
2014
Objectives: Lip lesions are a frequent cause of consultation in dentistry, as they comprise a signifi cant proportion of the oral lesions. The aim of the present study was to identify the different lip lesions and determine their prevalence in an Indian population. Material and methods: 5231 patients visiting a Department of Oral Medicine and Radiology were examined for the presence of different lip lesions during the period from October, 2011 to May, 2013. The statistical analysis was done using Chi-square test and p<0.05 was considered to be statistically signifi cant. Results: The age of the patients ranged from 8-70 years with a mean age of 32.6 years. The prevalence of lip lesions was …
Accessory submaxillary gland : two new case reports and a literature review
2020
Background The accessory submaxillary gland is a very uncommon anatomical variant, and incidence in the general population has not yet been quantified. The presence of pathology in these glands is rarer still, thus often going unnoticed. Material and methods We describe two accessory submaxillary gland cases, one asymptomatic and the other with chronic sialadenitis in the main and accessory gland caused by sialolithiasis. Although our diagnosis was by computerized tomography, magnetic resonance sialography is helpful to understand and describe this entity with greater precision. Results The first case report is an incidental finding and no intervention was required. However, case report num…
Non-Articular Rheumatism
1975
In terms of numbers of the population involved, this type of rheumatism is of the greatest significance.
Localization of parvalbumin, calretinin, and calbindin D-28k in identified extraocular motoneurons and internuclear neurons of the cat
1998
Calcium-binding proteins have been shown to be excellent markers of specific neuronal populations. We aimed to characterize the expression of calcium-binding proteins in identified populations of the cat extraocular motor nuclei by means of immunohistochemistry against parvalbumin, calretinin, and calbindin D-28k. Abducens, medial rectus, and trochlear motoneurons were retrogradely labeled with horseradish peroxidase from their corresponding muscles. Oculomotor and abducens internuclear neurons were retrogradely labeled after horseradish peroxidase injection into either the abducens or the oculomotor nucleus, respectively. Parvalbumin staining produced the highest density of immunoreactive …
Allozyme variation in populations of scallops, Pecten jacobaeus (L.) and P. maximus (L.) (Bivalvia: Pectinidae), across the Almeria–Oran front
2002
Abstract The scallops Pecten jacobaeus and P. maximus have been traditionally considered as different species which shared a common ancestor some 5 Ma ago. This view has been challenged by recent reports of genetic distances based on allozymes and mitochondrial DNA which are incompatible with such a long period of isolation and are more typical of conspecific populations. To explain the slight allozyme differentiation opposed to a clear morphological distinctiveness, two main hypotheses have been proposed. One hypothesis views interpopulation allozyme differentiation as an outcome of simple population genetic processes such isolation by distance. The other considers that the intertaxa alloz…
Physical education teacher educators: A 25-year scoping review of literature
2015
Abstract This paper presents a scoping review of literature on physical education teacher educators (1990–2014). The intent is to map research to date on this population and provide a useful context for the design and conduct of future scholarly inquiry. A total of 96 papers were included in the review. The included articles emerged from 15 countries and 25 journals. While much is known about US physical education teacher educators, there are many knowledge gaps regarding this population in other countries. The conclusions highlight a need for a co-ordinated approach to future research on physical education teacher educators.
