Our study aims to ascertain the results of speech therapy and surgery in patients who desire pitch alteration. Typically, patients desirous of an increase in their vocal pitch are male-to-female transpersons, and patients desirous of a drop in their pitch are puberphonia patients. This is a 3-year retrospective study of patients who have been operated for pitch alteration. This is a study of seven patients each of Wendlers glottoplasty (WG) and relaxation laryngeal framework surgery (RLFS). The records were reviewed for the preoperative and the 1-year post-operative fundamental frequency (FO), patient subjective satisfaction score (PSSS), and healing time. A total of 7/35 patients of puberphonia underwent RLFS in which the average preoperative F0 was 216 Hz and 1-year post-operative F0 was 114 Hz ( 0.004). The average pre- and post-operative PSSS was 4 and 9 ( 0.0004). Patients of WG had an average preoperative F0 of 153 Hz and 1-year post-operative F0 of 223 Hz ( 0.0005). The average pre and 1-year postoperative PSSS was 4 and 8 ( 0.002). The average healing time was 3 weeks 4 days in the RLFS patients and 8 weeks 5 days for WG patients. The results of RFLS yielded a high PSSS with a pitch drop of more than 100 Hz. The results of WG yielded an increase in the pitch of 70 Hz with a good PSSS. The average healing time taken following WG was double the time taken for RFLS.

Selective modal excitation in a multimode nanoslit by interference of surface plasmon waves.

Interference of surface plasmons has been widely utilized in optical metrology for applications such as high-precision sensing. In this paper, we introduce a surface plasmon interferometer with the potential to be arranged in arrays for parallel multiplexing applications. The interferometer features two grating couplers that excite surface plasmon polariton (SPP) waves traveling along a gold-air interface before converging at a gold nanoslit where they interfere.

This study explores the effect of sucrose addition on the properties of chiral nematic cellulose nanocrystal (CNC) films for potential food industry applications, including biodegradable packaging and food coloring. The addition of sucrose altered the films' structural color, shifting from blue in pure CNC films to aqua blue, green, yellow-green, and red with increasing sucrose concentrations (up to 21 %). Surface analysis revealed a reduction in contact angle from 96° to 48° due to sucrose's hydrophilic nature and smoother film surfaces.

The vestibular system is vital for maintaining stable vision during daily activities. When peripheral vestibular input is lost, patients initially experience impaired gaze stability due to reduced effectiveness of the vestibular-ocular-reflex pathway. To aid rehabilitation, patients are often prescribed gaze-stabilization exercises during which they make self-initiated active head movements.

Composite materials made of polymers and liquid crystals have been widely employed in smart windows, optical filters, and bistable displays. However, it is often difficult to decipher the role of the polymer network architecture on the alignment and the texture of liquid crystals. In this study, we use a simple model system where a small amount of polymerizable liquid crystalline monomer is mixed in a liquid crystal that exhibits both a smectic phase and a cholesteric phase with a large helical pitch.

Background: Difficulties with speech-in-noise perception in autism spectrum disorders (ASD) may be associated with impaired analysis of speech sounds, such as vowels, which represent the fundamental phoneme constituents of human speech. Vowels elicit early (< 100 ms) sustained processing negativity (SPN) in the auditory cortex that reflects the detection of an acoustic pattern based on the presence of formant structure and/or periodic envelope information (f0) and its transformation into an auditory "object".
Methods: We used magnetoencephalography (MEG) and individual brain models to investigate whether SPN is altered in children with ASD and whether this deficit is associated with impairment in their ability to perceive speech in the background of noise.
