Faddeev eigenfunctions for two-dimensional Schrodinger operators via the Moutard transformation

We demonstrate how the Moutard transformation of two-dimensional Schrodinger operators acts on the Faddeev eigenfunctions on the zero energy level and present some explicitly computed examples of such eigenfunctions for smooth fast decaying potentials of operators with non-trivial kernel and for deformed potentials which correspond to blowing up solutions of the Novikov-Veselov equation.Comment: 11 pages, final remarks are adde

Effects of synchronous music on 400-metre sprint performance

The aim of the present study was to assess the effects of motivating and oudeterous (neither motivating nor demotivating) synchronous music on 400-m sprint performance while controlling for the potential confound of pre-performance mood. A panel of volunteer Caucasian males ( n = 20; mean age = 20.5 years, s = 1.2) rated the motivational qualities of 32 musical selections using the Brunel Music Rating Inventory-2. An experimental group of volunteer Caucasian males ( n = 36; mean age = 20.4 years, s = 1.4) completed three 400-m time trials under conditions of motivational music, oudeterous music, and a no-music control. Pre-performance mood was assessed using the Brunel University Mood Scale (BRUMS). A series of repeated-measures analyses of variance with Bonferroni adjustment revealed no differences in the BRUMS subscales. A repeated-measures analysis of variance on the 400-m times showed a significant effect ( F 1.24, 42.19 = 10.54, P 2 = 0.24) and follow-up pair wise comparisons revealed differences between the synchronous music conditions and the control condition. This finding supported the first research hypothesis, that synchronous music would result in better performance than a no-music control, but not the second hypothesis, that performance in the motivational synchronous music condition would be better than that in the oudeterous condition. It appears that synchronous music can be applied to anaerobic endurance performance among non-elite sportspersons with a considerable positive effect

Individualized Music Improves Social Interaction of Women, But Not Men, With Dementia

Dementia is tragic both for patients with the disease and for their family members. As this neurodegenerative disorder progresses, cognitive functions deteriorate, agitation and aggression increase, and mood worsens (McDermott, Orrell, et al., 2014; Spiro, 2010; Vasionyté & Madison, 2013). Non-pharmacological approaches, such as active music therapy or passive music listening, can be effective in reducing these symptoms. However, no past studies have examined how music listening affects the social interactions of patients with dementia. As such, this study examined whether nursing home residents with dementia are more engaged and interactive if they listen to individually selected music for 15 minutes just prior to a visit with loved ones. Twelve nursing home residents (4 men, 8 women) with dementia (MMSE M=5.00, SD=7.25) and their loved ones experienced 5 visits preceded by music and 5 visits not preceded by music, with the exception of one resident who passed away after 3 music and 4 non-music visits. Following each visit, the loved one, blinded to the music vs non-music condition, completed a Social Interaction Questionnaire assessing the resident’s alertness, engagement, talkativeness, appropriateness, physical responsiveness, relaxation, happiness, agitation and repetitiveness. Results demonstrated that female residents’ social interactions were rated more positively, but male residents’ social interactions were rated more negatively, after music than non-music visits. These results support the efficacy of music as an intervention for improving the social interactions of women, but not men, with dementia

The MUSIC of Galaxy Clusters I: Baryon properties and Scaling Relations of the thermal Sunyaev-Zel'dovich Effect

We introduce the Marenostrum-MultiDark SImulations of galaxy Clusters (MUSIC) Dataset, one of the largest sample of hydrodynamically simulated galaxy clusters with more than 500 clusters and 2000 groups. The objects have been selected from two large N-body simulations and have been resimulated at high resolution using SPH together with relevant physical processes (cooling, UV photoionization, star formation and different feedback processes). We focus on the analysis of the baryon content (gas and star) of clusters in the MUSIC dataset both as a function of aperture radius and redshift. The results from our simulations are compared with the most recent observational estimates of the gas fraction in galaxy clusters at different overdensity radii. When the effects of cooling and stellar feedbacks are included, the MUSIC clusters show a good agreement with the most recent observed gas fractions quoted in the literature. A clear dependence of the gas fractions with the total cluster mass is also evident. The impact of the aperture radius choice, when comparing integrated quantities at different redshifts, is tested: the standard definition of radius at a fixed overdensity with respect to critical density is compared with a definition based on the redshift dependent overdensity with respect to background density. We also present a detailed analysis of the scaling relations of the thermal SZ (Sunyaev Zel'dovich) Effect derived from MUSIC clusters. The integrated SZ brightness, Y, is related to the cluster total mass, M, as well as, the M-Y counterpart, more suitable for observational applications. Both laws are consistent with predictions from the self-similar model, showing a very low scatter. The effects of the gas fraction on the Y-M scaling and the presence of a possible redshift dependence on the Y-M scaling relation are also explored.Comment: 22 pages, 25 figures, accepted for pubblication by MNRA
