During the Covid-19 pandemic, parents of students who carried out online learning were prone to experiencing low psychological well-being. Resilience is considered essential in mediating the relationship between religiosity and social support with psychological well-being. However, this role has yet to be tested empirically. This study examines the role of resilience as a mediator of the relationship between religiosity and social support with the psychological well-being of parents of students who carry out online learning during the Covid-19 pandemic. The research respondents totalled 281 parents living in the ex-Karesidenan Surakarta using the accidental sampling technique. Data analysis in this study used a simple mediation analysis with PROCESS macro analysis assisted by the SPSS v22.0 data analysis program. The study’s results prove that resilience mediates religiosity, social support, and psychological well-being. The mediation role of resilience is partial. The results of this study can be the basis for creating programs to improve the psychological well-being of parents through increased resilience, religiosity and social support.

The light-current charactersitics of a native-oxide-defined AlxGa1-xAs-GaAs quantum well heterostructure connected to a linear array were investigated. The results showed that the diodes featured high hysteresis in the light-current curve and featured switching from the stimulated to the spontaneous regime. The linear array acted as both a modulator and a switch for the stripe laser.

Individuals with autism spectrum disorder (ASD) commonly display speech processing abnormalities. Binding of acoustic features of speech distributed across different frequencies into coherent speech objects is fundamental in speech perception. Here, we tested the hypothesis that the cortical processing of bottom-up acoustic cues for speech binding may be anomalous in ASD. We recorded magnetoencephalography while ASD children (ages 7–17) and typically developing peers heard sentences of sine-wave speech (SWS) and modulated SWS (MSS) where binding cues were restored through increased temporal coherence of the acoustic components and the introduction of harmonicity. The ASD group showed increased long-range feedforward functional connectivity from left auditory to parietal cortex with concurrent decreased local functional connectivity within the parietal region during MSS relative to SWS. As the parietal region has been implicated in auditory object binding, our findings support our hypothesis of atypical bottom-up speech binding in ASD. Furthermore, the long-range functional connectivity correlated with behaviorally measured auditory processing abnormalities, confirming the relevance of these atypical cortical signatures to the ASD phenotype. Lastly, the group difference in the local functional connectivity was driven by the youngest participants, suggesting that impaired speech binding in ASD might be ameliorated upon entering adolescence.

Autism Spectrum (AS) is defined primarily by differences in social interactions, with impairments in sensory processing also characterizing the condition. In the search for neurophysiological biomarkers associated with traits relevant to the condition, focusing on sensory processing offers a path that is likely to be translatable across populations with different degrees of ability, as well as into animal models and across imaging modalities. In a prior study, a somatosensory neurophysiological signature of AS was identified using magnetoencephalography (MEG). Specifically, source estimation results showed differences between AS and neurotypically developing (NTD) subjects in the brain response to 25-Hz vibrotactile stimulation of the right fingertips, with lower inter-trial coherence (ITC) observed in the AS group. Here, we examined whether these group differences can be detected without source estimation using scalp electroencephalography (EEG), which is more commonly available in clinical settings than MEG, and therefore offers a greater potential for clinical translation. To that end, we recorded simultaneous whole-head MEG and EEG in 14 AS and 10 NTD subjects (age 15–28 years) using the same vibrotactile paradigm. Based on the scalp topographies, small sets of left hemisphere MEG and EEG sensors showing the maximum overall ITC were selected for group comparisons. Significant differences between the AS and NTD groups in ITC at 25 Hz as well as at 50 Hz were recorded in both MEG and EEG sensor data. For each measure, the mean ITC was lower in the AS than in the NTD group. EEG ITC values correlated with behaviorally assessed somatosensory sensation avoiding scores. The results show that information about ITC from MEG and EEG signals have substantial overlap, and thus EEG sensor-based ITC measures of the AS somatosensory processing biomarker previously identified using source localized MEG data have a potential to be developed into clinical use in AS, thanks to the higher accessibility to EEG in clinical settings.

We present an approach for obtaining generating functionals for density-functional-like theory, which takes into account the structure of electronic levels near Fermi surface and density variations at distances exceeding the screening radius in metals. Materials-specific information is contained mainly in these structure-dependent terms, while other terms depend mainly on the local density. We used proposed method to study the electronic structure of ferromagnetic Fe and Ni and obtain reasonable agreement with previous local density calculations and experiment. © 2001 American Institute of Physics.

The screened “exact” nonlocal exchange approach is applied to the calculation of magnetic susceptibility of transition metals, particularly to the calculation of spin-wave dispersion. We discuss the choice of an appropriate approach and aspects of linear muffin-tin orbital-atomic sphere approximation (ASA) calculations, in particular calculation of the Green function in the three-center approximation. We calculated transverse spin-wave frequencies in Fe with the local density approximation and with the nonlocal functional using both the “frozen” magnon method and calculation of bound state energies (corresponding to spin-wave excitations). © 2000 American Institute of Physics.

Fibrosing cholestatic hepatitis (FCH) is an aggressive form of hepatitis C virus (HCV) recurrence after orthotopic liver transplantation (OLT), which frequently results in graft failure and death. Treatment of FCH remains challenging, and the optimal antiviral therapy is yet to be determined. Between November 2013 and early 2015, 62 patients with HCV cirrhosis underwent OLT at our transplant center, of whom, 5 patients developed recurrence HCV in the form of severe FCH and were treated with sofosbuvir and simeprevir (SOF-SMV) for 24 weeks. All patients achieved significant improvement of HCV viral load and had undetectable viral PCR at 6-8 week of treatment. The HCV RNA remained undetectable throughout treatment course. The first two patients achieved SVR at week 12 after completion of the treatment. There were significant histologic and biomarkers improvements after initiation of the treatment. One patient developed refractory pruritus and acute pancreatitis. The second, fourth and fifth patients had very benign treatment courses with no side effects recorded. The third patient was starting the treatment with multiple comorbid conditions. His course was complicated with hepatic artery thrombosis, and later developed sepsis and renal failure. Therefore, it seems that the combination of SOF-SMV is an efficacious oral regimen in OLT recipient with recurrent hepatitis C and FCH. However, safety profile needs to be carefully evaluated.
