Aim: To assess whether amplitude-integrated electroencephalography (aEEG) alterations in the newborn period are associated with poor precursor skills of literacy at five years of age in children born preterm.
Methods: Between October 2007 and September 2011 248 preterm infants were eligible for the study at Innsbruck Medical University Hospital. aEEG was analysed for dominating background activity, calculation of the percentage of continuous activity, the Burdjalov scoring system, the minimum, mean and maximum amplitude. At the age of five years, we evaluated preterm born children by the Bielefelder screening (BISC) to assess for early diagnosis of reading problems and weak spelling and classified them as normal performers (n = 64) or poor performers (n = 20). Completion of testing was not possible for one infant.
Results: The minimum amplitude was significantly lower in the poor BISC performance group as compared to the normal BISC performance group at postnatal week two. The percentage of continuous background activity was significantly higher in infants with normal BISC performance than in infants with poor BISC performance at postnatal week three.
Conclusion: Children with poor developed precursor skills of literacy showed alterations in aEEG signals. The aEEG could be useful in further diagnosing preterm infants at risk for developmental complications.

BiScO-PbTiO-based ceramics show great potential in high-temperature piezoelectric applications. However, their high dielectric loss tan δ and low mechanical quality factor have to be optimized. In this paper, a ceramic system of (1-)Bi(ScZr)O-Pb(TiNi)O (BSZ-PT-Ni, = 0, 0.

Hexavalent chromium (Cr(VI)) is a highly toxic substance in wastewater, triggering grievous detriment to aquatic life and human health. Magnesium sulfite is spawned along with the desulfurization process in coal-fired power plants, which is usually disposed of as solid waste. Here, a "waste control by waste" method was proposed upon the redox of Cr(VI)-sulfite, in which highly toxic Cr(VI) is detoxicated and sequent enriched on a novel biochar-induced cobalt-based silica composite (BISC) due to the forced electron transfer from chromium to surface hydroxyl.

All-solid-state sodium batteries (ASSSBs) are attractive alternatives to lithium-ion batteries for grid-scale energy storage due to their high safety and ubiquitous distribution of Na sources. A critical component for ASSSB is sodium-ion conducting solid-state electrolyte (SSE). Here, we report a high-performance sodium-ion SSE with the recently developed bulk interfacial superionic conductor (BISC) concept.

Background: Preterm-born children are at higher risk for impaired linguistic abilities than are their term-born peers. The aim of the current study was to determine early predictors for delayed linguistic skills in very preterm-born preschool children.
Methods: Between January 2005 and November 2010 all very preterm infants born at < 32 weeks gestation in Tyrol were prospectively enrolled (n = 421); 248 of them had a detailed examination at the age of five years including cognitive assessment (Wechsler Preschool and Primary Scale of Intelligence, third edition (WPPSI-III) or Snijders-Oomen Nonverbal Intelligence Tests (SON-R)) as well as a screening test for language skills (Bielefelder screening for early diagnosis of reading problems and weak spelling (BISC)).
