H-MAC: A Hybrid MAC Protocol for Wireless Sensor Networks

, 2010
In this paper, we propose a hybrid medium access control protocol (H-MAC) for wireless sensor networks. It is based on the IEEE 802.11's power saving mechanism (PSM) and slotted aloha, and utilizes multiple slots dynamically to improve performance ...

Context‐Dependent Role of GDF15: GDF15+ Tumor‐Associated Macrophages Suppress OSCC Progression by Enhancing Phagocytosis

Advanced Science, EarlyView.
This study identifies GDF15+ TAMs as a cell subset mediating tumor regression after immunotherapy. Macrophage‐intrinsic GDF15 enhances phagocytosis and antigen cross‐presentation to CD8+ T cells through the NF‐κB signaling pathway, thereby inhibiting tumor progression.

RENAL‐CHIP: Rejection Evaluation via Non‐Invasive Analysis of Circulating Podocytes With Herringbone‐Chip Isolation Platform

Advanced Science, EarlyView.
RENAL‐CHIP converts 1 mL of peripheral blood into a biopsy‐equivalent readout of renal‐allograft fate. By magnetic capture and release of donor‐derived circulating podocytes through a herringbone microfluidic chip, 84% capture, 96% release and single‐cell RNA evidence of rejection‐specific immunity are achieved.

Legumain Restrains Granuloma Formation by Inhibiting mTORC1/STAT1‐Mediated M1 Macrophage Polarization in Sarcoidosis

Advanced Science, EarlyView.
Legumain (LGMN) is upregulated in macrophages during sarcoid‑like granuloma formation. Macrophage‑derived LGMN binds to integrin αvβ3 and suppresses mTORC1/STAT1 signaling to restrain M1 macrophage polarization. Intratracheal delivery of lipid nanoparticles carrying Lgmn plasmid DNA (pDNA) elevates LGMN expression and effectively attenuates pulmonary ...

A Conflict Avoidance Scheme for WiMedia Wireless Home Networks

International Journal of Distributed Sensor Networks, 2013
We propose an efficient resource reservation scheme for UWB (Ultrawideband) WPAN (Wireless Personal Area Network) with D-MAC (Distributed Medium Access Control). Since the WiMedia D-MAC supporting DRP (Distributed Reservation Protocol) scheme causes lots

An Energy Aware and Secure MAC Protocol for Tackling Denial of Sleep Attacks in Wireless Sensor Networks [PDF]

, 2019
Wireless sensor networks which form part of the core for the Internet of Things consist of resource constrained sensors that are usually powered by batteries. Therefore, careful energy awareness is essential when working with these devices.

Adhesion‐Related Macrophages Regulate Metabolic Homeostasis Through CAV‐1 Dependency

Advanced Science, EarlyView.
Adipose tissue harbors a distinct macrophage subpopulation, termed adhesion‐related macrophages (ARMs), which stably adhere to adipocytes. In obesity, ARMs represent the major expanding macrophage subset. They acquire material from adipocytes and rely on Caveolin‐1 for sustained lipid handling.

A Delayed-ACK Scheme for Performance Enhancement of Wireless LANs [PDF]

, 2003
The IEEE 802.11 MAC protocol provides a reliable link layer using Stop & Wait ARQ. The cost for high reliability is the overhead due to acknowledgement packets in the direction opposite to the actual data flow. In this paper, the design of a new protocol
