This paper examines the fit of three different statistical distributions to the returns of the S&P 500 Index from 1950-2005. The normal distribution is a poor fit to the daily percentage returns of the S&P 500. The lognormal distribution is a poor fit to single period continuously compounded returns for the S&P 500, which means that future prices are not lognormally distributed. However, sums o...

Cala meategia Ossa-Morena Zonaldean (OMZ) kokatzen da, Iberiar Mazizoaren hego-mendebaldean. Hango mineralizazioa nahiko konplexua denez, az- ken urteotan asko eztabaidatu da horren inguruan, baina berriki egin diren ikerketa- lanen arabera, mineralizazioaren zati bat bertan azaleratzen den skarn kaltziko bate- kin erlazionatuta dagoela interpretatu da. Lan honetan skarn-eko granateak datatu di...

Background: The association of sensorineural hearing loss (SNHL) in diabetes mellitus patients is known since decades, yet there no clear consensus among previous studies, with respect to the prevalence SNHL type 2 and effect duration control on acuity. Hence objectives this study are find loss. Methods: present was conducted 100 age gender matched non- diabetic controls group < 50 yrs, selecte...

The purpose of this study was to determine the effect of financial distress on investment behavior for the years of 2011 to 2016. The statistical population of the research is Tehran Stock Exchange. According to the systematic elimination method, 104 companies have been selected as the statistical sample. In this research, financial distress is independent variable and corporate investmen...

A novel miniature cell biosensor detection system for the detection of Hepatis B virus (HBV)-associated antigens and anti-HBV is described. The biosensor is based on "membrane-engineered" Vero fibroblast cells immobilized in an alginate matrix. The membrane-engineering process involved the electroinsertion of anti-HBV specific antibodies (anti-HBs, anti-HBe) or antigens (HBsAg) in the membranes...

The standard root−b1 test is widely used for testing skewness. However, several studies have demonstrated that this test is not reliable for discriminating between symmetric and asymmetric distributions in the presence of excess kurtosis. The main reason for the failure of the standard root−b1 test is that its variance formula is derived under the assumption of no excess kurtosis. In this paper...

Ferroelectric FET (FeFET) is a highly promising emerging non-volatile memory (NVM) technology, especially for binarized neural network (BNN) inference on the low-power edge. The reliability of such devices, however, inherently depends temperature. Hence, changes in temperature during run time manifest themselves as bit error rates. In this work, we reveal temperature-dependent model FeFET memor...

Internet of drones (IoD) has gained significant importance in recent times due to its applications several critical domains ranging from commercial defense and rescue operations. With flying different zones carry out specified tasks, the IoD can be beneficial gather real time data for interpretation by users. However, access is carried through an open channel battery operated drones. Therefore,...
