Frequency response computation for complex structures with damping and acoustic fluid [PDF]
, 2004 textModal frequency response analysis is a very economical approach for large and complex structural systems since there is an enormous reduction in dimension from the original finite element frequency response problem to the number of modes ...

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

Effects of Load Characteristic on Frequency Response of Generator Outage and Fast Reserve Requirement [PDF]
, 2022 The renewable penetration continues to increase and causes system inertia reduction. Once a generator unit outage occurs under different energy mix, it can easily impact the power system operation and affect the frequency stability. To avoid rapid system

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
