Best Regression for Eye Recognition

Human eye offers a number of opportunities for biometric recognition. The essential parts of the eye like cornea, iris, veins and retina can determine different characteristics. Systems using eyes’ features are widely deployed for identification in government requirement levels and laws; but also beginning to have more space in portable validation world. The first image was prepared to be used and monitored using CLAHE which means (Contrast Limited Adaptive Histogram Equalization) to improve the contrast of the image, after that the 3D surface plot was created for this image then different types of regression were used and the better one was chosen. The results showed that power regression is better, and fitter than other fitting methods (8th, 7th, 6th, 5th, 4th, 3rd, 2nd) degree polynomial, and straight line respectively, when depending on the sum of residual squared. The estimations of R-square demonstrated that (5th, 6th, 7th, 8th) have a great proportion of variance in the model followed by (power, 4th, 3rd, 2nd, straight line) respectively. The conclusion from these results is that the power regression has a better fitting than other types of fitting functions for this study and similar ones.

Phylogenomics and Historical Biogeography of Seahorses, Dragonets, Goatfishes, and Allies (Teleostei: Syngnatharia): Assessing Factors Driving Uncertainty in Biogeographic Inferences

The charismatic trumpetfishes, goatfishes, dragonets, flying gurnards, seahorses, and pipefishes encompass a recently defined yet extraordinarily diverse clade of percomorph fishes—the series Syngnatharia. This group is widely distributed in tropical and warm-temperate regions, with a great proportion of its extant diversity occurring in the Indo-Pacific. Because most syngnatharians feature long-range dispersal capabilities, tracing their biogeographic origins is challenging. Here, we applied an integrative phylogenomic approach to elucidate the evolutionary biogeography of syngnatharians. We built upon a recently published phylogenomic study that examined ultraconserved elements by adding 62 species (total 169 species) and one family (Draconettidae), to cover ca. 25% of the species diversity and all 10 families in the group. We inferred a set of time-calibrated trees and conducted ancestral range estimations. We also examined the sensitivity of these analyses to phylogenetic uncertainty (estimated from multiple genomic subsets), area delimitation, and biogeographic models that include or exclude the jump-dispersal parameter (j). Of the three factors examined, we found that the j parameter has the strongest effect in ancestral range estimates, followed by number of areas defined, and tree topology and divergence times. After accounting for these uncertainties, our results reveal that syngnatharians originated in the ancient Tethys Sea ca. 87 Ma (84–94 Ma; Late Cretaceous) and subsequently occupied the Indo-Pacific. Throughout syngnatharian history, multiple independent lineages colonized the eastern Pacific (6–8 times) and the Atlantic (6–14 times) from their center of origin, with most events taking place following an east-to-west route prior to the closure of the Tethys Seaway ca. 12–18 Ma. Ultimately, our study highlights the importance of accounting for different factors generating uncertainty in macroevolutionary and biogeographic inferences.

Using serum biomarkers for identifying unstable carotid plaque: update of current evidence

: Carotid atherosclerosis is responsible for a great proportion of ischemic strokes. Early identification of unstable or vulnerable carotid plaques and therefore of patients at high risk for stroke is of significant medical and socioeconomical value. We reviewed the current literature and discuss the potential role of the most important serum biomarkers in identifying patients with carotid atherosclerosis who are at high risk for atheroembolic stroke.

IDENTIFICATION OF A NEIGHBOUR (LUKE 10:25-37) IN NIGERIAN MULTI-CULTURAL CONTEXT

God, out of his goodness created humankind (Adam) in his own image and likeness, male and female he created them (Gen 1:27). God after creating them, he blessed them saying, “Be fruitful and multiply, fill the earth and subdue it; have dominion over the fish of the sea and over the birds of the air and over every living thing that move upon the earth” (Gen. 1:28). As mankind continued to live as was commanded, they turned inwards to subdue and dominate one another. Man against woman; village against village, town against town; state against state; region against region and worst of all tribe against tribe. This domination can come in the form of “stronger persons” dominating the “weaker ones,” “the stronger families” dominating “weaker families,” or “the stronger tribes” dominating “weaker tribes” etc. Jesus Christ when he came as God made man, he noticed these divisions among mankind hence on his last supper with his apostles he prayed, “That they may be one” (John.17: 11). He said it at the last supper to show how dear that unity is to his heart. St. Paul in trying to re-echo Jesus’ teaching among the Corinthians says, “Has Christ been divided?” (1Cor1:13). Whenever you gather among yourselves as Christians, there should be neither Jew nor Gentile, male or female, you are all one before God (Gal 3:28).The story of Good Samaritan is one of the ways through which Christ tried to tell us that we ought to look at one another fundamentally as image and likeness of God. The presence among Christians of tribal sentiments and loyalty to one’s ethnic group must be a scandal of great proportion to all of us who claim to be the agents for spreading Christ’s kingdom of love, and brotherhood in the world. Since we are now the authentic image of God, there ought not to be any form of division among us.

A dimensão ambiental na cultura educacional brasileira

As questões ambientais têm sido uma problemática contemporânea preocupante. A histórica relação do homem com a natureza a fim de modificá-la e adaptá-la às suas necessidades e aos seus interesses tem causado grandes distúrbios naturais de expressivas proporções. Diante dessa assertiva, tentamos analisar a dimensão ambiental na evolução humana e, especialmente, perceber essa dimensão no interior da educação brasileira. Palavras-chave: educação ambiental; cultura; educação brasileira. Abstract The environmental questions are a contemporaneous problem. The historical relation between men and nature in order to modify it and to adapt it to their necessities and to their interests has caused natural disturbances of great proportion. Therefore, we tried to analyze the environmental dimension in the human evolution and, especially, to perceive this dimension within Brazilian education. Keywords: environmental education; culture; Brazilian education.

Iodized Salt Between Myth and Reality: Assessment of Iodine Content in Table Salt Commercially Available in Romania

About 1/3 of the world population lives in areas where iodine is scarce. The easiest solution to provide an organism with adequate iodine doses is the iodization of table salt, a process implemented in about 120 countries. Romanian laws require the iodization of salt used for human consumption. The purpose of our study is to assess the iodine concentration of various table salt brands commercially available in Romania, from different countries � Ukraine, Belarus, Greece, Italy, Turkey, Austria, to see if they comply with accepted standards and compare them with those in our country. An iodometric titration method was used for analyzing the iodine content of the salt samples. The analysis of the samples indicate that a great proportion do not meet accepted standards regarding iodine concentration.

Relação entre Estrutura Ocupacional e Padrão Espacial dos Resultados Eleitorais

A great proportion of geography of voting can be related to the spatial division of labour. The geographical separation of people performing different economic roles within society occurs at a variety of scales, so geographical separation of people that votes differently occurs also at a variety of scales. In this paper, we try to consider and analyse the relationship between voting patterns and types of occupational activities.

Informal Loans in Russia: Why Not to Borrow from a Bank?

After the 2008 crisis, the Russian consumer loan market shows high growth rates, accompanied by the quality deteriorating even faster. At the same time, a great proportion of households are not attracted by the banks and borrow informally. In this paper, we aim to learn why households refuse to become bank clients, using the data from a 2009–2010 national survey of Russian households. Our results suggest that household's choice of the informal credit market is based not only on credit rationing, but also on a lack of financial literacy, credit discipline and trust in the banking sector as a whole.

From psychological to digital disengagement: exploring the link between ageism and the ‘grey digital divide’

<p>The need for digital literacy is apparent in today’s workplace, driven by strong pressures for constant technological innovation. Previous studies have shown that although older workers make up (and will make up) a great proportion of the workforce, there persists an age-based digital divide in the workplace; and the outcome of such divide is quite negative: at the individual level, older workers feel they’re being marginalized and as such, become dissatisfied and disengage from their workplace; at the organizational level, a pool of skills and expertise is lost as a result of the older worker’s disengagement, putting at risk effective knowledge transfer and mentoring process. Hence, the importance of a deeper understanding of the contextual factors that may feed the <strong>‘</strong>grey digital divide<strong>’ </strong>in the workplace. The goal of this paper is to address such factors moving beyond the ageist claim that a worker’s chronological age is the driving force behind the <strong>‘</strong>grey digital divide<strong>’</strong>.</p>
