WiFi CSI cannot substitute for wearable IMU: 6-11% weighted accuracy on 27 activities versus 73-80% for IMU

Using the Multimodal Activity Sensing Dataset (MASD; 27 activities, 20 participants), the study tests whether ambient WiFi Channel State Information (CSI) can substitute for a body-worn inertial measurement unit (IMU) in human activity recognition; the authors find that the dataset's released machine-learning-ready files expose a degraded signed CSI representation rather than the documented amplitude, so they rebuild amplitude and antenna-ratio Doppler from the raw complex CSI, recover omitted participant identifiers, and re-evaluate subject-independently under a controlled multi-seed protocol, finding WiFi systematically weak: every backbone they try reaches only 6-11% weighted accuracy on the 27-class set against 73-80% for IMU, with usable accuracy on 0 of 27 activities; the corrected r

ADAMTS14 cleaves collagen V to keep matrix stable; its loss weakens YAP nuclear translocation and IPF fibroblast activation

Using an unbiased druggable-genome siRNA screen, this study identified ADAMTS14 as a regulator of YAP nuclear translocation; single-cell and spatial transcriptomics of IPF patient lungs localized ADAMTS14 to a CTHRC1-high myofibroblast population enriched in fibroblastic foci, and knockdown or knockout of ADAMTS14 in IPF patient-derived lung fibroblasts reduced pro-fibrotic, matrisome, and TGFβ-response gene expression; mechanistically, collagen V was identified as an ADAMTS14 substrate whose impaired processing shifted the COL1:COL5 ratio from about 50:1 to about 20:1, producing an unstable matrix with disorganized focal adhesions and reduced FAK-AKT signaling and force transmission.

Loss or blockade of myeloid TLR2 improves survival and reduces neutrophils and lung inflammation in influenza-infected neonatal mice

Combining human cord blood monocytes with a neonatal mouse influenza model, this study found that neonatal monocytes sustain higher TLR2 expression after LTA or IAV stimulation, while TLR2 gene deletion, anti-TLR2 antibody blockade, or myeloid-specific TLR2 deletion improved survival of IAV-infected neonatal mice (for example, 61% versus 25% survival for TLR2−/− versus wild-type neonates, and 46% versus 7% with anti-TLR2 antibody), accompanied by reduced neutrophils at 6 days post-infection, lower histopathology scores in myeloid conditional knockouts, and no further rise in IL-6, TNF-α, MCP-1, CXCL1, and CXCL2 from 3 to 6 days post-infection, suggesting that myeloid TLR2 signaling exacerbates neonatal susceptibility to respiratory viral infection by amplifying pulmonary inflammation.
