It is known that the muscles actuate human hand joints with a coordinated manner and the hand postures can be reconstructed by a few (usually two) inputs through postural synergies, which has been applied in robotic hand design for reproducing the human versatile grasp function. As for the mechanical implementation, in terms of the joints implemented postural synergies, due to the excessive number...
Gene controls biological character by various proteins that are formed by isoforms. Through alternative splicing, gene can express multiple isoforms. The next generation of high-throughput RNA sequencing has provided facilitation for quantifying isoform expression level. Extensive efforts have been made in stimulating isoform abundance from RNA-Seq data, but the accuracy still needs to be improved...
This paper proposes statistical analysis of phase-only correlation functions between two signals with stochastic phase-spectra. We derive the expectation and variance of the phase-only correlation functions assuming phase-spectra of two input signals to be bivariate probability variables. As a result, we give expressions for the expectation and variance of phase-only correlation functions in terms...
Feature selection methods have been widely used in gene expression analysis to identify differentially expressed genes and explore potential biomarkers for complex diseases. While a lot of studies have shown that incorporating feature structure information can greatly enhance the performance of feature selection algorithms, and genes naturally fall into groups with regard to common function and co-regulation,...
The purpose of this study was to investigate the effect of morning-night differences and sleep deprivation on situation awareness and driving performance. Twelve male students (mean of age 21.0±0.7 years old) participated in this study. They drove in following driving scenarios under three conditions: night condition, morning condition with and without sleep deprivation, on a driving simulator. Statistical...
This article presents a new method of image analysis with steganographic inserts based on hierarchy analysis method. Images with applied algorithm of replacing the least significant bit (LSB) are investigated. Detection is performed by dividing the image into layers and making an analysis of zero-layer of adjacent bits for every bit. First-layer and second-layer are analyzed too. Hierarchies analysis...
Applications are generally written assuming a predictable and well-behaved OS. In practice, they experience unpredictable misbehavior at the OS level and across OSes: different OSes can handle network events differently, APIs can behave differently across OSes, and OSes may be compromised or buggy. This unpredictability is challenging because its sources typically manifest during deployment and are...
Consumers usually evaluate storage time of a beef, as well as its freshness, using its surface color. However, in this study, by using a colorimetric method, we found that the surface color change of beef samples was unrecognizable during the first five days of storage. On the other hands, the attenuance difference between 615nm and 630nm (A630-A615 difference) was found to have a high correlation...
The intent of our study, conducted on a sample of 98 psychiatric outpatients, was to explore the correlations between executive functions and traits of temperament and character. Executive functions were assessed through Frontal Assessment Battery and the traits of temperament and character using the Temperament and Character Inventory. From our sample, a significant link between certain traits of...
The aim of this paper is to propose optimization techniques for source stirred reverberation chambers. In particular, the stirring function is accomplished by 62 monopole antennas distributed on the chamber walls, and subsequently fed two at a time for a total of 1891 combinations. At first it is shown how an irregular placement of the antenna increases the chamber performances. Subsequently, an optimization...
Twitter has transformed from an online platform for communication to a mega content generator for all kinds of topics. The topic of posts (or tweets) generated on Twitter cover diverse topics of interests. For example, politics, public personalities, events and corporate organizations. In this study, we analysed if tweets related to corporate organizations can predict the financial market. Our analysis...
Today, crowdfunding has emerged as a popular means for fundraising. Among various crowdfunding platforms, reward-based ones are the most well received. However, to the best knowledge of the authors, little research has been performed on rewards. In this paper, we analyze a Kickstarter dataset, which consists of approximately 3K projects and 30K rewards. The analysis employs various statistical methods,...
To investigate spatial distribution properties of the cardiac- and respiratory-driven cerebrospinal fluid (CSF) motions in the intracranial space, correlation mapping technique was conducted. Time series of CSF velocity were acquired in 7 healthy subjects of 26±5 years old under by asynchronous 2-dimensional phase contrast (2D-PC) method with 217-msec temporal resolution. The delay time and maximum...
We study a unique behavioral network data set (based on periodic surveys and on electronic logs of dyadic contact via smartphones) collected at the University of Notre Dame. The participants are a sample of members of the entering class of freshmen in the fall of 2011 whose opinions on a wide variety of political and social issues and activities on campus were regularly recorded — at the beginning...
The ability of the human mind to perceive visual informationmakes visualization not only useful, but a powerful toolfor information discovery. Answering questions about complexrelationships requires the analyst to choose a statistical analysistechnique that makes relationships visually discernible. Oftenthe proper technique is dependent on the characteristics of thedataset, such as dependency among...
An epileptic seizure is a brief episode of symptoms due to abnormal excessive or synchronous neuronal activity in the brain. Epilepsy is a chronic disorder that affects people of all ages, and one of the most common neurological diseases globally. Epilepsy can have both genetic and acquired causes, nevertheless, the exact mechanism of epilepsy is still unknown. It merits further investigation under...
As the important factors affecting the economic growth, system innovation and technological innovation have been widely attended. But there is little quantitative research on them. According to the theory of grey correlation analysis, this paper calculates the contribution degree to the economic growth through 10 indexes which can measure the system and technological innovation from 2005 to 2014....
The complexity of a system needs to be understood completely in order to build and run successful systems. Cybernetics Influence Diagram is a qualitative model which has been used in a large program for depiction of the system complexity [11][12][13]. The depiction is qualitative in nature. Generally the subject matter experts (SME) try to understand the complexity of a system by capturing the influences...
In content-centric networking, the schemes of innetwork caching can affect the performance of the whole network. Existing schemes lack of the global view, which results in inefficient caches. In this paper, we aim to analyze the real-time distribution of contents among caches from multiple perspectives. This paper proposes TCBRP, a scheme that analyzes caching tendency of various contents in reverse...
Bayesian networks are described based on correlation coefficients of the second, third, and the higher orders. The growth of orders for the correlation coefficients is proved to result in significant decrease in probabilities of the 2nd type errors. It testifies indirectly that the efficiency of the multivariate statistical analysis increases if the dimension of the correlation moments goes up. If...
