Unravelling the nonlinear generation of designer vortices with dielectric metasurfaces.

Vortex beams are currently drawing a great deal of interest, from fundamental research to several promising applications. While their generation in bulky optical devices limits their use in integrated complex systems, metasurfaces have recently proven successful in creating optical vortices, especially in the linear regime. In the nonlinear domain, of strategic importance for the future of classical and quantum information, to date orbital angular momentum has only been created in qualitative ways, without discussing discrepancies between design and experimental results.

Null subject comprehension and production revisited: a look at English and Italian.

This study will investigate how children acquire the option to drop the subject of a sentence, or null subjects (e.g., "Tickles me" instead of "He tickles me").

Amplitude and Phase Changes in Electrocochleographic Real-Time Recordings During Cochlear Implantation and Its Relation to Pre- and Postoperative Hearing.

Background: The aim of this study was to relate response patterns of electrocochleography (ECochG) recordings during cochlear implantation to pre- and postoperative hearing.

Methods: Thirty subjects with either flat (FA, n = 9) or sloping (SA, n = 21) audiograms before cochlear implantation were prospectively included. Real-time ECochG recordings were conducted via the cochlear implant.

A new species of Uropeltis Cuvier, 1829 (Serpentes: Uropeltidae) from the eastern escarpment of the southern Western Ghats, India.

A new species of the uropeltid ('shieldtail') snake genus Uropeltis is described based on eight specimens from the southern part of peninsular India's Western Ghats. Uropeltis caudomaculata sp. nov.

Outcomes of traumatically injured patients after nighttime transfer from the intensive care unit.

Background: Prior studies have associated nighttime transfer of patients from the intensive care unit (ICU) with increased morbidity. This study sought to examine this relationship in traumatically injured patients, as this has not been previously performed.

Methods: A retrospective review of traumatically injured patients admitted to a Level I Trauma Center's ICU from January 2021 to September 2022 was performed.
