Purpose: Spectral resolution is imperative for complex listening tasks such as understanding speech in the presence of background noise and has a significant role in children, particularly classroom learning. The present study evaluated the auditory spectral resolution abilities of children with Benign epilepsy with centrotemporal spikes (BECTS).
Method: This cross-sectional study conducted from August 2017 to March 2020 recruited 23 children with clinical and electrographic features consistent with BECTS as cases. Fifteen age and sex matched typically developing children (TDC) were taken as controls. Spectral resolution abilities were evaluated using the recently developed Spectral temporally modulated Ripple test (SMRT).
Results: The mean age of the cases was 10.63 ± 1.91 years with a slight male preponderance (69%). The mean (±SD) SMRT thresholds in the cases and controls were 5.90 (±1.91) and 7.21 (±1.03) respectively. The auditory spectral resolution threshold measured by SMRT in children with BECTS was observed to be significantly lower when compared to the controls (p of 0.021).
Conclusion: Children with BECTS have a lower spectral resolution threshold by SMRT.

Proton magnetic resonance spectroscopy (MRS) offers a non-invasive, repeatable, and reproducible method for in vivo metabolite profiling of the brain and other tissues. However, metabolite fingerprinting by MRS requires high signal-to-noise ratios for accurate metabolite quantification, which has traditionally been limited to large volumes of interest, compromising spatial fidelity. In this study, we introduce a new optimized pipeline that combines LASER MRS acquisition at 11.

Modification of silica interfaces by covalent attachment of functional ligands is a primary means of controlling the interfacial chemistry of porous silicas used in separations, environmental cleanup, and biosensing. Recently, modification of hydrophobic, -alkyl-silane-functionalized interfaces has been achieved through self-assembly of zwitterionic phospholipids or mixed-charged surfactants to form "hybrid bilayers", producing interfaces that mimic lipid-bilayer partitioning and provide shape-selective partitioning of aromatic hydrocarbons. Charged headgroups, however, introduce electrostatic interactions that strongly influence the retention of ionizable solutes and require careful control over pH and ionic strength in the solution phase.

The detection of pesticide residues in agricultural products is crucial for ensuring food safety. However, traditional methods are often constrained by slow processing speeds and a restricted analytical scope. This study presents a novel method that uses filter-array-based hyperspectral imaging enhanced by a dynamic filtering demosaicking algorithm, which significantly improves the speed and accuracy of detecting pesticide residues.

Crystallization from the melt is a critical process governing the properties of semi-crystalline polymeric materials. While structural analyses of melting and crystallization transitions in bulk polymers have been widely reported, in contrast, those in thin polymer films on solid supports have been underexplored. Herein, in situ Raman microscopy and self-modeling curve resolution (SMCR) analysis are applied to investigate the temperature-dependent structural changes in poly(ethylene oxide) (PEO) films during melting and crystallization phase transitions.

The spectrum of carbon monoxide is important for astrophysical media, such as planetary atmospheres, interstellar space, exoplanetary and stellar atmospheres; it also important in plasma physics, laser physics and combustion. Interpreting its spectral signature requires a deep and thorough understanding of its absorption and emission properties. A new accurate spectroscopic model for the ground and electronically-excited states of the CO molecule computed at the aug-cc-pV5Z CASSCF/MRCI+Q level is reported.
