Fault-tolerant consensus in directed graphs and convex hull consensus
… problems under different fault models in communication networks that are modeled as arbitrary directed graphs, i.e., two pairs of nodes may not share a bi- directional communication channel, and not every pair of nodes may be able to communicate with each other directly or indirectly. We …

Magnetless circulators based on linear time-varying circuits
… becomes crucial. For this reason, full‐duplex communication, which doubles the transmission rate over a certain bandwidth compared to currently deployed half-duplex radios by operating the uplink and the downlink simultaneously on the same frequency, has been brought back into the spotlight …

THE MOLECULAR AND BEHAVIORAL CHARACTERIZATION OF THE MURINE CRE – LOXP SKELETAL MUSCLE SYNTHESIZED BDNF KNOCKOUT MODEL
… (msBDNF) is thought to facilitate the crucial bi-directional communication between the motor neuron and the muscle fibers it innervates. Since 2008, the Ottem Laboratory has investigated the role of msBDNF by employing Cre/LoxP recombinase technology to selectively delete the BDNF coding region …

Diet Modifies the Neuroimmune System by Influencing Macrophage Activation
… as macrophages, produce cytokines that mediate communication of the peripheral immune status to the brain. This cytokine network establishes a bi-directional communication between the innate immune system and the central nervous system. Cytokine signaling in the brain leads to an organized …

Explicit disclosure in retail communication: Impact of undetermined social network site relationships on branded identity
… on social network sites, which allows for multi-directional communication between identity functions. Findings also suggest that consumer control on social network sites has created a two-way communication channel by which the retailer becomes an equal to all members. An amended version of de …

An Examination of the Discourse in a Graduate Mathematics Methods Course
… graduate mathematics methods course. Theories of communication developed a framework for analyzing discourse. Theories on teacher knowledge formed a framework for analyzing the types of teacher knowledge the prospective teachers encountered. Additional theories of self-efficacy and motivation were …
