Purpose: Delays in the diagnosis and treatment of infantile hypertrophic pyloric stenosis (IHPS) may lead to laboratory and clinical decompensation in infants. The aim of this study was to determine whether pyloric measurement parameters can be effectively used in the clinical prognosis of IHPS by evaluating the relationship between pyloric dimensions on ultrasonographic evaluation at the time of presentation and clinical and laboratory parameters in infants with pyloric stenosis.
Methods: A retrospective observational study was conducted on 122 infants who were followed up with the diagnosis of IHPS in our neonatal clinic and operated on by a pediatric surgeon between January 2005 and December 2020.
Next-generation data networks need to support Tb/s rates. In-phase and quadrature (IQ) modulation combine phase and intensity information to increase the density of encoded data, reduce overall power consumption by minimizing the number of channels, and increase noise tolerance. To reduce errors when decoding the received signal, intersymbol interference must be minimized.

These require flexible/wearable systems adaptable to body motions, thus materials conformable to non-planar surfaces, and able to maintain performance under mechanical distortions. Here, fibre PDs are prepared by combining rolled graphene layers and photoactive perovskites.

Methods: The records of patients who underwent infra-areolar subcutaneous mastectomy for adolescent gynecomastia between January 2004 and December 2021 were reviewed retrospectively.
Article Synopsis
- - Harmonic generation occurs through non-linear interactions between light and matter, allowing the conversion of optical signals to higher frequencies, which is crucial for optics technology.
- - Researchers achieved significant progress by demonstrating third harmonic generation at 9.63 THz using single-layer graphene and a circular split ring resonator array, pumped by a 3.21 THz frequency quantum cascade laser.
- - This innovative method leverages graphene's nonlinearity and resonator design to enhance pump power density, unlocking access to the 6-12 THz frequency range, a challenging area for compact source development due to limitations with traditional semiconductors.
