Ultrasensitive Diamond Cantilever‐Based Optical Microphone

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
The first demonstration that high quality diamond cantilevers function as high‐sensitivity acoustic transducers is reported, combining CVD diamond cantilevers and an extrinsic Fabry‐Perot optical configuration. High transduction efficiency yields record sensitivity (51.5 VPa−1) and MDP (0.018 µPa/Hz$\rm {\sqrt {Hz}}$), enabling durable, low‐noise ...

Laparoscopic Partial Splenectomy for a Giant Congenital Splenic Cyst in a Child: Case Report and Focused Literature Review

open access: yesClinical Case Reports, Volume 14, Issue 1, January 2026.
ABSTRACT An 11‐year‐old boy with a 16 × 14.5 cm congenital splenic cyst underwent laparoscopic upper‐pole partial splenectomy after negative hydatid workup and vaccination. Recovery was uneventful; histology confirmed epithelial cyst. Spleen‐preserving surgery provided durable symptom relief and preserved function.

"Set phasors to stun": an algorithm to improve phase coherence on transients in multi-microphone recordings [PDF]

open access: yes, 2007
Ever since the advent of multi-microphone recording, sound engineers have wrestled with the colouration of sound by phasing issues. For some this was an anathema; for others this colouration was a crucial ingredient of the finished product. Traditionally,

A Protocol for Microprism‐Based Two‐Photon Imaging Of The Lateral Cortex In The Mouse Inferior Colliculus

open access: yesCurrent Protocols, Volume 6, Issue 1, January 2026.
Abstract The inferior colliculus (IC) is a central hub for auditory information processing that receives widespread convergent projections. The IC comprises three main subdivisions: the central nucleus of the IC (ICC), the dorsal cortex (DC), and the lateral cortex (LC). While the ICC receives primarily ascending auditory information, DC and LC receive
