The electromagnetic effects in Ke4K_{e4} decay

The final state interaction of pions in $K_{e4}$ decay allows one to obtain the value of the isospin and angular momentum zero $\pi\pi$ scattering length $a_0^0$.We take into account the electromagnetic interaction of pions and isospin symmetry breaking effects caused by different masses of neutral and charged pions and estimate the impact of these effects on the procedure of scattering length extraction from $K_{e4}$ decay.Comment: 8 pages,1 figur

The isospin symmetry breaking effects in Ke4K_{e4} decays

The Fermi-Watson theorem is generalized to the case of two coupled channels with different masses and applied to final state interaction in $K_{e4}$ decays. The impact of considered effect on the phase of the $\pi\pi$ scattering is estimated and shown that it can be crucial for scattering lengths extraction from experimental data on $K_{e4}$ decays

INDICATORS OF CLASSICALITY/QUANTUMNESS OF FINITE- DIMENSIONAL SYSTEMS

We discuss measures of classicality/quantumness of states of finite-dimensional quantum systems, which are based on a deviation of quasiprobability distributions from true statistical distributions

Longitudinal relationships between caloric expenditure and gray matter in the cardiovascular health study

Background: Physical activity (PA) can be neuroprotective and reduce the risk for Alzheimer’s disease (AD). In assessing physical activity, caloric expenditure is a proxy marker reflecting the sum total of multiple physical activity types conducted by an individual. Objective:To assess caloric expenditure, as a proxy marker of PA, as a predictive measure of gray matter (GM) volumes in the normal and cognitively impaired elderly persons. Methods: All subjects in this study were recruited from the Institutional Review Board approved Cardiovascular Health Study (CHS), a multisite population-based longitudinal study in persons aged 65 and older. We analyzed a sub-sample of CHS participants 876 subjects (mean age 78.3, 57.5% F, 42.5% M) who had i) energy output assessed as kilocalories (kcal) per week using the standardized Minnesota Leisure-Time Activities questionnaire, ii) cognitive assessments for clinical classification of normal cognition, mild cognitive impairment (MCI), and AD, and iii) volumetric MR imaging of the brain. Voxel-based morphometry modeled the relationship between kcal/week and GM volumes while accounting for standard covariates including head size, age, sex, white matter hyperintensity lesions, MCI or AD status, and site. Multiple comparisons were controlled using a False Discovery Rate of 5 percent. Results: Higher energy output, from a variety of physical activity types, was associated with larger GM volumes in frontal, temporal, and parietal lobes, as well as hippocampus, thalamus, and basal ganglia. High levels of caloric expenditure moderated neurodegeneration-associated volume loss in the precuneus, posterior cingulate, and cerebellar vermis. Conclusion:Increasing energy output from a variety of physical activities is related to larger gray matter volumes in the elderly, regardless of cognitive status.Cyrus A. Raji, David A.

Acid-Base Properties Of Glass Substrate And SiO[2]-Bi[2]O[3]Thin-Film Systems Obtained On It

The article describes an experimental research as a result of which SiO[2]–Bi[2]O[3] films have been synthesized of film-forming solutions based on tetraethoxysilane and bismuth nitrate (III). Acid-base properties of a glass substrate and SiO[2]–Bi[2]O[3] films obtained on it have been studied. The dependency of physical and chemical properties of SiO[2]–Bi[2]O[3] composites on their percentage composition have been revealed

Propagation of Magnetic Fields from Electrical Domestic Appliances

The article presents a research into propagation of magnetic fields from electrical domestic devices. A safe distance at which magnetic induction does not exceed the background level is determined for each type of devices. It is proved that there are two stages of increasing magnetic induction as the distance from the source increases. At the first stage magnetic induction rises and electromagnetic field is formed. At the second stage exponential decrease of magnetic field induction takes place. Mathematical regularities of propagation of magnetic field from electrical domestic devices are experimentally educed

The results of research are presented for new stud lines of Kalmyk cattle: Pirat 6626, Pokhvalny 8643, and Ozhog 6136.To assess meat productivity, carcass morphological composition, physical and chemical properties, amino acid and fatty acid compositions of muscle tissue, control slaughter of young bulls (15 months old) of different breed lines was carried out. The slaughtershowed a higher weight of fresh carcass in bulls of Pirat 6626 line, which was 215.9 kg. Weight of Pokhvalny 8643 and Ozhog 6136 lines was lower, 212.5 kg in average. Bulls of new lines insignificantly differed by the dressed weight and slaughter yield amountedto 221.4 to 223.9 kg (56.0% to 56.4%), respectively. At slaughter, carcasses of all experimental animals were characterized by a good yield of deboned meat (82.3 to 82.6%) with a relatively small bone content (17.4 to 17.7%). Compared to bulls of Pokhvalny 8643 and Ozhog 6136 lines, Pirat 6626 line had water binding capacity higherby 1.96 and 1.09%, and juice loss during cooking was lower by 0.76 and 0.90%.Chemical composition analysis of deboned meat showed a higher protein content in meat from Pokhvalny 8643 bulls (23.41%) than from Pirat 6626 (20.95%) and Ozhog 6136 (21.75%) lines. Fat content in the meat of Pirat 6626 and Ozhog 6136 bulls was higher than in Pokhvalny 8643 bulls and amounted to 2.84 and 2.99%.In proteins of animals from all three lines, the content of essential amino acids exceeds the levels recommended by FAO/WHO for humans; there are no limiting amino acids.The maximum lysine amino acid score was observed in proteins of Pirat 6626 animals, which was higher by 3.6% than in Pokhvalny 8643 line and by 7.9% than in Ozhog 6136 line; leucine and isoleucine were higher in proteins of Pirat 6626 and Ozhog 6136 lines.Valine amino acid score was higher in muscle proteins of Pirat 6626 bulls (120.0%), than in the proteins of Pokhvalny 8643 (110.0%) and Ozhog 6136 (114.0%) lines.In Pokhvalny 8643 bulls, methionine amino acid score had the smallest difference with the reference protein. The minimal difference in phenylalanine amino acid score with the reference protein was also observed in Pokhvalny 8643 bulls and amounted to 5.0%.According to the results of protein biological value calculation, Pokhvalny 8643 line has more balanced ratio of essential amino acids of 89.7%, while Pirat 6626 and Ozhog 6136 lines show ratios of 81.6% and 81.7%, respectively.Differences in fatty acid composition of intramuscular fat from bulls of all three lines are insignificant, but Pokhvalny 8643 line shows some superiority in the content of  polyunsaturated acids by 0.48 to 0.33%.Sensory assessment of boiled beef and meat broth quality from new lines of Kalmyk young cattle was «good» and «very good».Представлены результаты исследований новых заводских линий калмыцкой породы крупного рогатого скота: Пирата 6626, Похвального 8643 и Ожога 6136.Для оценки мясной продуктивности, морфологического состава туш, физико-химического, аминокислотного и жирнокислотного составов мышечной ткани был проведен контрольный убой молодняка (бычков) в 15-месячном возасте разной линейной принадлежности, который показал более высокую массу парной туши у бычков линии Пирата 6626 — 215,9кг, Похвального 8643 и Ожога 6136 ниже — в среднем 212,5кг.
