Kondo insulators have recently aroused great interest because they are promising materials that host a topological insulator state caused by the strong electron interactions. Moreover, recent observations of the quantum oscillations in the insulating state of Kondo insulators have come as a great surprise. Here, to investigate the surface electronic state of a prototype Kondo insulator YbB12, we measured the transport properties of single crystals and microstructures. In all samples, the temperature dependence of the electrical resistivity is insulating at high temperatures and the resistivity exhibits a plateau at low temperatures. The magnitude of the plateau value decreases with reducing sample thickness, which is quantitatively consistent with the surface electronic conduction in the bulk insulating YbB12. Moreover, the magnetoresistance of the microstructures exhibits a weak-antilocalization effect at low field. These results are consistent with the presence of a topologically protected surface state, suggesting that YbB12 is a candidate material for a topological Kondo insulator. The high field resistivity measurements up to µ0H = 50 T of the microstructures provide supporting evidence that the quantum oscillations of the resistivity in YbB12 occurs in the insulating bulk.

Background: Previous studies exploring the impact of atopic dermatitis (AD) in children focused on factors associated with parental quality of life at one point in time. Objective: To examine factors associated with change of quality of life among parents of children affected with AD. Methods: The study cohort comprised 98 parent–children pairs treated for AD at the Clinic of Dermatovenereology; however, 18 parents (18.4%) were lost to follow‐up after 1 year. Children were assessed with SCORing Atopic Dermatitis Index (SCORAD) and Children Dermatology Life Quality Index (CDLQI) or the Infants' Dermatitis Quality of Life Index (IDQOL), depending on their age. Parents filled in socio‐demographic questionnaire and Dermatitis Family Impact Questionnaire (DFI). After 1 year, both children and parents were reassessed using the same AD‐related battery of questionnaires. Results: After follow‐up, a significant improvement in the average total DFI score was observed, especially for domains of fatigue/exhaustion, emotional distress and impact of helping in child treatment. Lower baseline SCORAD, greater improvement of SCORAD over follow‐up, better CDLQI/IDQOL at baseline, greater improvement in CDLQI/IDQOL over follow‐up, not having asthma and having older child with AD were associated with better parental quality of life after 1 year of follow‐up. Parental higher education level, shorter AD duration, better baseline SCORAD and greater improvement in CDLQI/IDQOL over follow‐up were associated with greater improvement in parental life quality over 1 year of follow‐up. Conclusion: Contributors to parental quality of life after 1 year included clinical features of AD and child's comorbidity (asthma), but also the perception of child's quality of life and its improvement.

Particle-in-cell simulations of (m = 2; n = 1) tearing mode in cylindrical plasmas are carried out with kinetic electrons using the split-weight control-variate algorithm [Y. Chen and S. E. Parker, J. Comput. Phys. 220, 839 (2007)]. Radially, global simulation shows global mode structure in agreement with reduced-magnetohydrodynamic eigenmode calculation. Simulations of the tearing layer are verified with analytic results for the collisionless, semi-collisional, and drift-tearing mode. [ABSTRACT FROM AUTHOR]

Duchenne muscular dystrophy (DMD) is the most common form of muscular dystrophy during childhood. Mutations in dystrophin (DMD) gene are also recognized as a cause of cognitive impairment. We aimed to determine the association between intelligence level and mutation location in DMD genes in Serbian patients with DMD. Forty-one male patients with DMD, aged 3 to 16 years, were recruited at the Clinic for Neurology and Psychiatry for Children and Youth in Belgrade, Serbia. All patients had defined DMD gene deletions or duplications [multiplex ligation- dependent probe amplification (MLPA), polymerase chain reaction (PCR)] and cognitive status assessment (Wechsler Intelligence Scale for Children, Brunet-Lezine scale, Vineland-Doll scale). In 37 patients with an estimated full scale intelligence quotient (FSIQ), six (16.22%) had borderline intelligence (70
