The goal of the present investigation was to perform a registered replication of Jones and Macken's (1995b) study, which showed that the segregation of a sequence of sounds to distinct locations reduced the disruptive effect on serial recall. Thereby, it postulated an intriguing connection between auditory stream segregation and the cognitive mechanisms underlying the irrelevant speech effect. Specifically, it was found that a sequence of changing utterances was less disruptive in stereophonic presentation, allowing each auditory object (letters) to be allocated to a unique location (right ear, left ear, center), compared to when the same sounds were played monophonically.

Since the release of the first 3D-printed firearm, "The Liberator," the occurrence of 3D-printed firearms in criminal activities has increased, highlighting the need for forensic research on these weapons. This study presents a technical examination of a 3D-printed firearm received by the National Institute of Criminalistics and Criminology (NICC), focusing on its design, ballistic performance, and its potential for microscopic comparative analysis. The firearm, resembling a 3D-printed pistol Yeet22, is primarily constructed from polymer parts, with the exception of the firing pin, barrel, and various springs and screws.

Acute Kidney Injury (AKI) is a significant medical condition characterized by the abrupt decline in kidney function.Low-intensity pulsed ultrasound (LIPUS), a non-invasive therapeutic technique employing low-intensity acoustic wave pulses, has shown promise in promoting tissue repair and regeneration. A novel LIPUS system was developed and evaluated in rat AKI models, focusing on its effects on glomerular filtration rate (GFR), blood urea nitrogen (BUN), serum creatinine (SCr), and the Notch1-Akt-eNOS signaling pathway.
