Optical properties of poly-silicon material are investigated to be integrated in new silicon photonics devices, such as capacitive modulators. Test structure fabrication is done on 300 mm wafer using LPCVD deposition: 300 nm thick amorphous silicon layers are deposited on thermal oxide, followed by solid phase crystallization anneal. Rib waveguides are fabricated and optical propagation losses measured at 1.31 µm. Physical analysis (TEM ASTAR, AFM and SIMS) are used to assess the origin of losses. Optimal deposition and annealing conditions have been defined, resulting in 400 nm-wide rib waveguides with only 9...

BACKGROUND: Both, maternal borderline personality disorder (BPD) and maternal major depressive disorder (MDD) are often associated with adverse consequences for children, including increased risk for child behavior problems. Reduced maternal emotional availability might play a critical role in transmitting maternal psychopathology on the child. Our aim was to investigate the association between emotional availability and maternal BPD and MDD in remission (rMDD), and if this interrelatedness mediates the association between maternal mental disorders and child behavior problems...

Suicide is one of the leading causes of death among young people globally. In light of emerging evidence supporting the effectiveness of school-based suicide prevention programmes, an analysis of cost-effectiveness is required. We aimed to conduct a full cost-effectiveness analysis (CEA) of the large pan-European school-based RCT, Saving and Empowering Young Lives in Europe (SEYLE). The health outcomes of interest were suicide attempt and severe suicidal ideation with suicide plans. Adopting a payer's perspective, three suicide prevention interventions were modelled with a Control over a 12-month time period...

The hypothalamus-pituitary-adrenal axis (HPAA) and its end product, the glucocorticoid cortisol, has been shown to be associated with psychopathology. Determining cortisol concentrations in hair (HCC) allows the investigation of long-term HPAA-activity. There is a significant scarcity of studies investigating the link between HCC and psychopathology and quality of life in child and adolescent samples. In addition, as the HPAA constitutes a feedback system enabling adaption to environmental demands, it is important to consider the socio-environmental context that the children grow up in...

Herein we present design, synthesis, chiral HPLC resolution, and kinetics of racemization of axially chiral Ni(II) complexes of glycine and di-(benzyl)glycine Schiff bases. We found that while the ortho-fluoro derivatives are configurationally unstable, the pure enantiomers of corresponding axially chiral ortho-chloro-containing complexes can be isolated by preparative HPLC and show exceptional configurational stability (t1/2 from 4 to 216 centuries) at ambient conditions. Synthetic implications of this discovery for the development of new generation of axially chiral auxiliaries, useful for general asymmetric synthesis of α-amino acids, are discussed...

Mixed and inconsistent findings have been reported across languages concerning grammatical morphology in speakers with Autism Spectrum Disorders (ASD). Some researchers argue for a selective sparing of grammar whereas others claim to have identified grammatical deficits. The present study aimed to investigate this issue in 26 participants with ASD speaking European French who were matched on age, gender and SES to 26 participants with typical development (TD). The groups were compared regarding their productivity and accuracy of syntactic and agreement categories using the French MOR part-of-speech tagger available from the CHILDES...

We study the fully nonlinear time evolution of a holographic system possessing a first order phase transition. The initial state is chosen in the spinodal region of the phase diagram, and it includes an inhomogeneous perturbation in one of the field theory directions. The final state of the time evolution shows a clear phase separation in the form of domain formation. The results indicate the existence of a very rich class of inhomogeneous black hole solutions.

BACKGROUND: Patent ductus arteriosus (PDA) occurs more frequently in premature infants. Depending on the degree of prematurity, these children often have other serious comorbidities that could significantly impact on surgical outcome. AIM: This study aimed to evaluate clinical results of the surgical ligation of PDA in extremely low body weight preterm infants with birth weight below 750 grams and to identify risk factors of mortality. METHODS: A total of 31 preterm infants with birth weight below 750 grams and significant PDA were operated between 2006 and 2016 through posterolateral thoracotomy (n=16) or with the use of video-assisted thoracoscopic (VATS) method (n = 15)...

BACKGROUND: Manganese-enhanced magnetic resonance imaging (MEMRI) is an increasingly popular alternative to standard functional MRI methods in animal studies. The contrast in MEMRI images is based on the accumulation of Mn2+ ions inside neurons, and, since manganese can serve as calcium analogue, this accumulation reflects calcium dynamics providing versatile information about brain neuroarchitecture and functionality. However, despite its use as a functional imaging tool, the exact relationship between the MEMRI signal and neuronal activity remains elusive...

Resting state heart rate variability (HRV) is a psychophysiological marker that has gained increasing research interest, in particular in developmental neuroscience. HRV has been shown to be associated with mental and physical health, beyond simple measures of heart rate (HR) and shows inter- and intraindividual variance across aging. Recently, three studies reported on a positive correlation between resting state HRV and cortical thickness in selected regions of interest (ROIs) in adult samples. Structural thickness, HRV, and HR change during the sensitive period of adolescence...

BACKGROUND: Bladder cancer (BC) is recognized as environmentally related. The interaction of environmental exposure to chemicals and genetic susceptibility seem to play important roles in BC development. In order to improve diagnosis and the recognition of BC risk, a group of markers which combine genetic susceptibility with detoxification and nuclear matrix protein (NMP22) is proposed. OBJECTIVES: The aim of the study was to examine the utility of nuclear matrix protein (NMP22) as a diagnostic marker in BC in genetic susceptibility (NAT2 slow acetylators) combined with detoxification abilities (glutathione S-transferase GST and isoenzyme GST-π)...
