The discrete Fourier transform (DFT) algorithms are commonly used in frequency estimation. The interpolation direction of the interpolated algorithms based on DFT is always defined by the information of spectral amplitude, such as the Rife algorithm. In the case of low signal to noise ratio (SNR), false decision of the interpolation direction occurs sometimes. However, decreasing false rate of ...

This study examines the relationship between speech characteristics and personality traits by drawing on pseudo-naturalistic conversations dimensions identified Myers–Briggs Type Indicator (MBTI) model which assesses four of introversion-extroversion, sensing-intuiting, thinking-feeling, judging-perceiving. The 30 participants was recorded transcribed, after a number features including pitch, l...

OBJECTIVE Pain perception is affected by psychological, social, medical, and environmental conditions, and contributes to the patient's treatment satisfaction and response. Better understanding of pain perception will likely improve pain assessment and treatment selection. The objective of this study was to define a range of verbal and nonverbal pain responses to a clinical stimulus in a clinic...

How should society judge the safety and efficacy of drugs? This was the question posed by England’s chief medical officer, Sally Davies, in February 2015. Citing controversies about oseltamivir (Tamiflu) and statins, as well as growing disquiet about overmedication by doctors and conflicts of interest among researchers, she feared an erosion of public trust and asked the Academy of Medical Scie...

An impressive fit to historical data suggests to biologists that a given ecological model is highly valid. Models often achieve this fit at the expense of exaggerated complexity that is not justified by empirical evidence. Because overfitted theories complement the traditional assumption that ecology is 'messy', they generally remain unquestioned. Using predation theory as an example, we sugges...

The production of protective neutralizing antibodies occurs quickly in some viral infections but very slowly in others. In a new study, surface glycoproteins (the targets of neutralization) of 2 different viruses were genetically switched. Analysis of the neutralizing antibody response to each of the 2 parent and recombinant viruses in infected mice revealed that the speed of neutralizing antib...

Patients with corticobasal degeneration (CBD) have calculation impairments. This study examined whether impaired number knowledge depends on verbal mediation. We focused particularly on knowledge of very small numbers, where there is a precise relationship between a cardinality and its number concept, but little hypothesized role for verbal mediation. We evaluated accuracy and reaction time (RT...

Experienced gymnasts are considered by many to be landing experts, because they are able to successfully land from heights of 3m or more (McNitt-Gray, 1993). Although gymnasts may be landing experts, their landing mechanics cannot be determined solely by optimal landing strategies because the judging system places constraints on how a landing is to be performed. Gymnasts spend many years perfec...

Sheffield’s contribution to the interactive cross language information retrieval track took the approach of comparing user’s abilities at judging the relevance of machine translated French documents against ones written in the users’ native language: English. Conducting such an experiment is challenging, and the issues surrounding the experimental design are discussed. Experimental results stro...
