Background/objectives
Survivors of pediatric brain tumors (SPBT) experience significant social challenges, including fewer friends and greater isolation than peers. Difficulties in face processing and visual social attention have been implicated in these outcomes. This study evaluated facial expression recognition (FER), social attention, and their associations with social impairments in SPBT.

Phylogenetic comparative methods are often used to test functional relationships between traits. However, million‐year macroevolutionary observational datasets cannot definitively prove causal links between traits—correlation does not equal causation and experimental manipulation over such timescales is impossible. Although this caveat is widely understood, it is less appreciated that different phylogenetic...
Mobile filters are required to process increasing RF power levels, driven by the need for higher data-rates and improved cell-edge coverage. This results in more demanding filter specifications for loss, rejection, isolation, linearity and reliability, while, at the same time, handset OEMs require smaller filter footprints.
Topological Insulators (TI) have been the subject of intense research by condensed matter physicists over the last decade for many reasons. One of which is the existence of helical edge modes, which can occur even when wave propagation through the bulk of the material is impossible. Eager to engineer devices that support these helical modes, researchers have invented classical systems analogous to...
Recent trends in RF filter design has brought the necessity to design SAW resonators with boosted performance. Most importantly, improvements in both the resonators' quality factors (Q) and temperature coefficient of frequency (TCF) are needed. TC-SAW concept employing 128 Y-cut LiNbO3 has attracted considerable practical interest in this view. Some excellent works from Qorvo have demonstrated the...
Background Laparoscopic antireflux surgery is highly effective in patients with uncomplicated gastroesophageal reflux disease (GERD). However, long-term failure rates in paraesophageal hernia (PEH) and Barrett’s metaplasia (BE) are higher and warrant a more durable repair. Outcomes for the laparoscopic Nissen fundoplication (LNF) and Hill repair (LHR) are equivalent, but their anatomic components...
