Materials and Methods: Peak systolic velocity and end diastolic velocity were measured by the duplex Doppler ultrasonography in the anterior and median cerebral arteries in 60 asphyxiated and 50 healty term infants in the first five days of life. Resistive index and pulsatility index values were calculated. T test and Mann-Whitney test was used for statistical analysis to compare asphy xiated a...

Methods We conducted a retrospective review of all patients of 16 years and under that underwent aspiration with or without washout of suspected septic joint from January 2005 to March 2011. Cases were defined as any patient with an organism identified on microbiology culture. The association between clinical features, laboratory results, operative findings and gram stain examination were compa...

INTRODUCTION Early detection of social anxiety and loneliness might be useful to prevent substantial impairment in personal relationships. Understanding the way people use smartphones can be beneficial for implementing an early detection of social anxiety and loneliness. This paper examines different types of smartphone usage and their relationships with people with different individual levels ...

We introduce a family of multiscale, orientation-selective, non-parametric features (“ranklets”) modelled on Haar wavelets. We clarify their relation to the Wilcoxon ranksum test and the rank transform and provide an efficient scheme for computation based on the Mann-Whitney statistics. Finally, we show that ranklets outperform other rank features, Haar wavelets, SNoW and linear SVMs (based on ...

Materials and methods We evaluated 49 patients (51.2±7.7 yrs.) with a confirmed diagnosis of diabetes. The subjects were randomized in two groups according to glycated hemoglobin-HbA1c: HbA1c < 7% and HbA1c >7%. The fasting plasma glucose and HbA1c were performed in a specialized laboratory and HR and iRR were recorded for 10 min in the supine position. Statistical analysis included Shapiro-Wil...

We investigate gravitational waves with sub-nanoHz frequencies ($10^{-11}$ Hz $\lesssim f_{\rm GW} \lesssim 10^{-9}$ Hz) from the spatial distribution of spin-down rates milli-second pulsars. As we suggested in Yonemaru et al. 2018, a single source induces bias observed pulsars depending on relative direction between and pulsar. To improve constraints time derivative gravitational-wave amplitud...

PURPOSE To determine the analgesic efficacy of percutaneous vertebroplasty in treating osteoblastic and mixed spinal metastases. MATERIALS AND METHODS Fifty-two patients underwent 59 vertebroplasty procedures for 103 painful vertebral metastases, among which 53 were pure osteoblastic and 50 were mixed (blastic and lytic). Analgesic efficacy was classified as "excellent," "good," "fair," and "...
