A Chronographic Method of Measuring Reverberation Time [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1930
A description is given of apparatus which measures the rate of decay of sound density in a room. A loud speaker, energized from an oscillator, is preferably used as the source of sound. Current is sent through the speaker until the sound in the room has reached a steady state, whereupon the speaker is disconnected from the oscillator and the time ...

A study on the preferred level of late reverberation in speech and music

open access: yes, 2022
S.29-34This paper studies how the aesthetic preference of late reverberation depends on the mixing level of the reverberation. Towards this goal, three subjective listening tests are presented.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The skills required for transition to university and study in biological sciences: A student perspective

open access: yesFEBS Open Bio, EarlyView.
Bioscience students were asked for their opinions on the value and teaching of skills. 204 responded that teamwork, time management and study skills are necessary to reach University, that scientific writing, research, laboratory and presentation skills are taught effectively during their studies, while other skills are gained inherently through study ...

Optimizing acoustic conditions for two lecture rooms in Faculty of Agriculture, Cairo University

open access: yesAin Shams Engineering Journal, 2017
This paper analyses the acoustic conditions inside two lecture rooms in faculty of agriculture, Cairo University, based on field measurements and simulation technique. Ambient noise and reverberation time were measured in the unoccupied rooms.

Linear frequency modulated reverberation suppression using time series models

open access: yes, 2022
When active radar and sonar systems are used for target detection and tracking, boosting target detection, and tracking efficiency is the most important challenge in real-time reverberation.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

open access: yesFEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...
