Mathematical Modeling for Neuropathic Pain: Bayesian Linear Regression and Self-Organizing Maps Applied to Carpal Tunnel Syndrome
2020
A better understanding of the connection between risk factors associated with pain and function may assist therapists in optimizing therapeutic programs. This study applied mathematical modeling to analyze the relationship of psychological, psychophysical, and motor variables with pain, function, and symptom severity using Bayesian linear regressions (BLR) and self-organizing maps (SOMs) in carpal tunnel syndrome (CTS). The novelty of this work was a transfer of the symmetry mathematical background to a neuropathic pain condition, whose symptoms can be either unilateral or bilateral. Duration of symptoms, pain intensity, function, symptom severity, depressive levels, pinch tip grip force, a…
Dentin degradonomics – The potential role of salivary MMP-8 in dentin caries
2019
Background Dentin caries involves dissolution of minerals which eventually leads to degradation of organic matrix. This degradation which was thought to be by bacterial proteases is now considered to be orchestrated by endogenous collagenases such as Matrix Metalloproteinases (MMPs). This paper aims to estimate the salivary levels of MMP-8 in dental caries and also to asses the various risk factors that contribute to the formation of dental caries. Material and methods A random sample of 75 adults aged 18-35 were included and categorized based on the number of caries lesions (MCL). Standard clinical examinations were performed, and stimulated saliva was collected and analyzed for concentrat…
Inverse association between type 2 diabetes and aortic root dimension in hypertensive patients
2017
Background Some data support the concept that aortic root diameter (ARD) in hypertension may be regarded as a marker of subclinical organ damage. The impact of type 2 diabetes mellitus (DM) on cardiac structure and function is known, although the relationship between DM and ARD is not clear. The aim of our study was to evaluate the influence of DM on ARD in hypertensive patients. Methods We enrolled 1693 hypertensive patients (aged 63.7 ± 9.6 years). The population was divided into two groups: the first one with DM (n = 747) and the second one without DM (n = 946). ARD was measured by echocardiography at level of Valsalva's sinuses using echocardiography M-mode tracings. It was considered a…
Study on the Correlation Between Working Capital and Economic Value Added for the Companies Relating to the Hotel and Restaurant Industry Listed on t…
2020
In the present study was determined the influence of the value change of the working capital on the variation of the economic value added indicator on a sample consisting of a number of 26 companies (2007-2017) belonging to the hotel and restaurant industry, listed on the Bucharest Stock Exchange. The correlation between the indicators was achieved by using the multiple linear regression method. The study showed that there is a strong link between the two economic indicators, over 80% of the change in economic value being explained by the change in working capital. It was found that a 1% increase in working capital, for the period 2007-2017, had the effect of increasing the economic value a…
The Influence of Hedonic and Utilitarian Motivators on Likelihood to Buy a Tourism Package
2013
To fully understand the pattern of choice, it is important that any explanation of consumer behavior to be accompanied by a complete understanding of the interplay between a consumer’s functional goals and experiential preferences within the decision context. Consumer researchers have increasingly begun to investigate consumer choice based on distinctions that involve the purchase and consumption of goods for pleasure versus for more utilitarian and instrumental purposes. Consumers are often faced with these types of choices between hedonic and utilitarian alternatives that are at least partly driven by emotional desires rather than cold cognitive deliberations. This research approaches fac…
Buying Intentions Influenced by Various Determinants in Tourism
2014
Marketing has acquired a central role in tourism because it helps organizations to create value in transactions with buyers. Thus, this important area of any business process is used to educate consumers, to add value to their experience in tourism, and to seek new ways to reward loyalty through innovative schemes (e.g., programs for frequent travelers). This paper presents the examination of the responses of 154 tourists in relation to their intention to purchase a travel package and the factors that are usually decisive in the decision making process regarding tourism services, factors that could also create the loyalty that any tourism enterprise can create through marketing.
Nekustāmā īpašuma vērtēšanas modeļi
2015
Bakalaura darbs veltīts nekustāmā īpašuma masveida vērtēšanas problemātikai. Bakalaura darbā apskatīti nekustāmā īpašuma masveida vērtēšanas pamatprincipi un vērtēšanā izmantotie modeļu tipi. Darbā apskatīta ratio analīzes metodoloģija, kas tiek izmantota masveida vērtēšanas rezultātu novērtēšanai. Aprakstot spēkā esošo dzīvokļa īpašuma vērtēšanas modeli, ko izmanto Valsts zemes dienests, darbā piedāvāts vērtēt dzīvokļa īpašumu kā vienotu īpašumu, nedalot tās vērtību atsevišķās sastāvdaļas, tādās kā zeme, koplietošanas telpas un dzīvokļa īpašuma telpu grupas, kā arī veikti citi esošā modeļa uzlabojumi. Pārejot uz vienota īpašuma vērtēšanas principu, ar lineārās regresijas palīdzību iegūts j…
Multiplicity of solutions for asymptotically linear $n$-th order boundary value problems
2007
In this paper we investigate existence and multiplicity of solutions, with prescribed nodal properties, to a two-point boundary value problem of asymptotically linear $n$-th order equations. The proof follows a shooting approach and it is based on the weighted eigenvalue theory for linear $n$-th order boundary value problems
Associations of physical performance and physical activity with mental well-being in middle-aged women
2021
Abstract Background To investigate whether physical performance is independently of physical activity (PA) associated with positive and negative dimensions of mental well-being in middle-aged women. Methods Data were drawn from the Estrogenic Regulation of Muscle Apoptosis (ERMA) study in which women 47 to 55 years were randomly selected from the Finnish National Registry. They (n = 909) participated in measurements of physical performance (handgrip force, knee extension force, vertical jumping height, maximal walking speed, and six-minute walking distance). Both mental well-being (the Centre for Epidemiologic Studies Depression Scale, the International Positive and Negative Affect Schedule…
Technical and economical comparison between NdFeB and hard ferrites linear electrical generators from sea waves
2015
In this paper the authors perform a technical-economic comparison of two different Tubular Permanent Magnet Linear Machines for sea waves generation by using finite elements analysis. The first configuration includes ferrite rings while the second configuration includes neodymium-iron-boron rings. In order to compare the two types in economic and technical terms, a detailed analysis of the main figures of merit of the two configurations has been carried out. In particular, significant data such as flux distribution, rated voltage and current, axial force, electric power, realization cost and maintenance cost have been compared.
