The phonon instability and thermal equation of state of Mo are extensively investigated using density functional theory. The calculated phonon dispersion curves agree well with experiments. Under compression, we captured a large softening in the transverse acoustic (TA) branches of body-centred cubic Mo. When the pressure is raised to 716 GPa, the frequencies along Γ-N in the TA branches soften...

We present the first tomographic reconstruction algorithm for optical molecular imaging that is based on the equation of radiative transfer. The reconstruction code recovers the spatial distribution of fluorescent sources in highly scattering biological tissue. An objective function, which describes the discrepancy of measured near-infrared light with predicted numerical data on the tissue surf...

BACKGROUND The Hoffstein formula is the most widely used equation to predict optimal CPAP pressure in patients with obstructive sleep apnea, but it is based on data from white patients. The purpose of this study was to develop an equation for optimal CPAP based on data from Asian patients, and to compare this new formula with the Hoffstein formula. METHODS We retrospectively reviewed the reco...

We studied the possibility of predicting PaO2 during exercise of a given oxygen uptake (VO2) from resting pulmonary function tests (PFTs) in patients with chronic obstructive pulmonary disease (COPD). The three-minute incremental treadmill exercise was performed with serial measurements of PaO2 via intra-arterial catheter in 46 patients (mean FEV1 = 1.09 +/- 0.49L, mean FEV1/FVC = 44 +/- 15 per...

We aimed to develop a word-reading test for Korean-speaking adults using irregularly pronounced words that would be useful for estimation of premorbid intelligence. A linguist who specialized in Korean phonology selected 94 words that have irregular relationship between orthography and phonology. Sixty cognitively normal elderly (CN) and 31 patients with Alzheimer's disease (AD) were asked to r...

present study tested a model consisting work ability as dependent variable and leadership effectiveness and perceived organizational support as independent variable, with job satisfaction as its mediator. data were gathered from a sample of 330 employees of an industrial organization in iran, who were selected by stratified random sampling method. of this sample, 72 percent were men and average...

PURPOSE The purpose of this study was to propose mathematical models for predicting mandibular growth direction and amount in children with normal skeletal relationship from 4 to 9 years of age using the craniofacial characteristics found on the head films. METHODS Lateral cephalograms of 27 Japanese children with normal occlusion at 4 (T1) and 9 (T2) years of age were traced and measured. Fi...

The data obtained from the analyses of the samples described above were used to develop response surface equations which would predict the effect of the irradiation dose and temperature on each vitamin over the entire area covered by the design. From the equation for the response surface for thiamin loss the predicted losses in pork chops irradiated at 0 'C and then cooked were as follows: 0 kG...

BACKGROUND & OBJECTIVES Leptospirosis, a zoonosis with a worldwide distribution is an acute febrile illness caused by spirochaetes of the pathogenic Leptospira interrogans. Microscopic agglutination test (MAT), the reference method for diagnosis was successively done to evaluate the modified ELISA which was developed with the recombinant LipL32 antigen for the detection of anti-leptospiral anti...
