Poster abstract : Energy-efficient rate adaptive MAC Protocol (RA-MAC) for long-lived sensor networks [PDF]

, 2009
This paper introduces an energy-efficient Rate\ud Adaptive MAC (RA-MAC) protocol for long-lived Wireless Sensor\ud Networks (WSN). Previous research shows that the dynamic\ud and lossy nature of wireless communication is one of the major\ud challenges to

scH16S‐Seq Maps Klebsiella pneumoniae‐Associated Myeloid States and Reveals a CD38–NAD Immunometabolic Axis That Impairs Lysosomal Acidification in Sepsis

Advanced Science, EarlyView.
Single‐cell host–bacterial 16S co‐sequencing (scH16S‐seq) integrates cell‐associated bacterial 16S‐derived signals with host transcriptomes to resolve bacterial signal‐enriched myeloid states in Klebsiella pneumoniae sepsis. Complementary pharmacological and genetic analyses define a CD38–NAD immunometabolic axis connecting mitochondrial bioenergetic ...

Inhibition of MEKK3 Prevents Cerebral Cavernous Malformation Progression Via Restoring Endothelial Integrity and Restricting Microglial Activation

Advanced Science, EarlyView.
In this study, we demonstrate that aberrant MEKK3 signaling in endothelial cells and microglia drives the progression of cerebral cavernous malformations (CCMs). Furthermore, we identify DPDH as a potent small‐molecule MEKK3 inhibitor with substantial therapeutic potential for CCM treatment.

Performance modelling of the o-mac protocol

, 2007
In this paper we derive a qualitative model for O-MAC, an energy efficient MAC protocol designed for sensor networks. Through this model we study how each parameter, such as packet sending rate, node density and end-to-end hop lengths, affects the ...

Bioengineered Stroma‐Camouflaged Nanovesicles Disrupt the IDO1/CD276 Immunosuppressive Circuit to Reinvigorate Antitumor Immunity

Advanced Science, EarlyView.
Bioengineered stroma‐camouflaged nanovesicles (AM@UIO‐BMS/DOX) convert the immunosuppressive tumor niche into an immunoresponsive milieu by disrupting the IDO1/CD276 circuit. Anti‐CD276 membrane camouflage guides tumor accumulation and deep penetration, enabling controlled co‐delivery of DOX and the IDO1 inhibitor BMS‐986205.

Immune Biomarkers of Islet Transplant Rejection Revealed by Synthetic Immunological Niche

Advanced Science, EarlyView.
A subcutaneous synthetic immunological niche (IN) enables serial, minimally invasive monitoring of immune responses after islet transplantation. Flow cytometry and transcriptomic profiling of the IN reveal immune‐cell programs associated with graft acceptance and distinct types of rejection.
