E and rapid energy storage is essential for sustainable energy delivery. Fast transfer of charges stored at the surface of supercapacitor electrodes can provide high power densities (fast (dis)charge rates). However, their exclusively non-Faradaic energy storagemechanism limits attainable energy densities. In contrast, electrochemical reactions in intercalation or conversion electrodes can affo...

BACKGROUND Chronic abdominal pain is a common worldwide problem and known to be associated with psychological problems. This study evaluated the association between abdominal pain-predominant functional gastrointestinal disorders (AP-FGIDs), psychological maladjustment and personality traits in adolescents. METHODS Adolescents aged 13-18 years were recruited from 5 randomly selected schools i...

Guirao-Goris et al. have recently presented a structured review of physical activity questionnaires for older adults and the elderly. Since physical activity is considered a cornerstone to prevent chronic diseases, it is compulsory to monitor physical activity for public health strategies. In this review, a special focus was given by the authors to present physical activity questionnaires valid...

We show that the coherent state quantization of massive particles in 1+1 de Sitter space exhibits an ordering property: There exist some classical observables A and A∗ such that OA∗pOAq = OA∗pAq p, q ∈ Z, where OA is the quantum observable corresponding to the classical observable A.

Recall that a commutative domain R in which every finitely generated ideal is principal is called a Bézout domain. By definition, a noetherian Bézout domain is a principal ideal domain. Several examples of non-noetherian Bézout domains are listed in [1], 243-246. Recall also that a commutative domain R is called an Elementary Divisor domain if, given any matrix A with coefficients in R, there e...

Poor air quality (PAQ) is a global concern, especially in urban areas, and often seen as an important element of social sustainability given its negative impact on health life. However, little research has been undertaken cities the developing world to explore how residents perceive poor quality, main causes, what control measures should be used address PAQ where responsibility rests for implem...

The main goal of a data collection protocol for sensor networks is to keep the network’s database updated while saving the nodes’ energy as much as possible. To achieve this goal without continuous reporting, data suppression is a key strategy. The basic idea behind data suppression schemes is to send data to the base station only when the nodes’ readings are different from what both nodes and ...
