A directional preference ETX measure for the collection tree protocol in mobile sensor networks
… preference Estimated Transmissions Count (ETX) measure was developed for the Collection Tree Protocol (CTP) in order to create longer lasting links. This thesis describes and measures the performance of this directional preference ETX measure utilizing various metrics such as Packet …

High-throughput routing for multi-hop wireless networks
The expected transmission count (ETX) metric is a new route metric for finding high-throughput paths in multi-hop wireless networks. The ETX of a path is the expected total number of packet transmissions (including retransmissions) required to successfully deliver a packet along that path. For …

The Origin of Multiple Sclerosis Revisited: The Case for a Soluble Toxin
… toxin, Clostridium perfringens epsilon toxin (ETX), may be the long sought environmental trigger for MS. ETX is a neurotoxin with a unique tropism for the brain tissues that are specifically damaged during acute MS exacerbations, the blood-brain barrier and the myelin sheath. Using a Western …

Ethosuximide stabilizes sleep-related oscillations and reduces sleep fragmentation during alcohol withdrawal
… we examined the effects of ethosuximide (ETX), a purported T-type calcium current inhibitor, and genetic suppression of a T channel subtype on SROs and sleep in mice during ethanol exposure and withdrawal. In the first study, we observed reversal of withdrawal-mediated disruptions in SROs …

Routing in heterogeneous wireless ad hoc networks
… to the expected number of transmissions (ETX) metric are developed. The first metric, ETX1, reduces the route length by increasing the transmission power. The routing and MAC layers assume the presence of bidirectional links for their proper operation. However networks with omnidirectional …

OPTICALLY-INDUCED POPULATION DISCHARGE THRESHOLD TESTING: A NOVEL INVESTIGATION OF A MURINE MODEL OF ALCOHOL WITHDRAWAL INDUCED CNS HYPEREXCITABILITY
… with treatment with the drug ethosuximide (ETX) during WD. ETX is a Ca2+ channel blocker which has been shown to reduce WD anxiety-like behavior, certain seizure types associated with thalamic dysfunction, and mortality in an animal model of WD. Our results indicate that the …

ELUCIDATING DIFFERENT CLOSTRIDIUM PERFRINGENS TYPE D VACCINE PROTOCOLS IN EWES AND LAMBS
… perfringens type D epsilon toxin (CptD ETX) is a major cause of sudden mortality in lambs. Protection of neonatal lambs relies heavily on maternally derived antibodies (MDA) transferred through colostrum; however, these antibodies may also influence the lamb’s immune response to …

Towards the design of an energy-aware path selection metric for IEEE 802.11s wireless mesh network
… that have been analysed in literature including ETX. ETX has been used in WMNs but was not developed specifically for mesh. In conclusion, EAPM conserves more energy than the Multimetric, airtime link metric and lastly ETX. The simulation experiments show that EAPM optimises the energy used in …

Performance evaluation of routing metrics for wireless mesh networks
… metric for WMNs. Four routing metrics (HOP, ETX, RTT, and EETT) were chosen for evaluation after comparing twenty existing routing metrics. The overall results of the experiments show that ETX outperformed all the other routing metrics that were simulated, but it is not the best routing …

The application of network coding to multicast routing in wireless networks
… similar to that of wired multicast by using the ETX metric to build unicast routing trees. We also compare MORE-M to a multicast enabled variant of the ExOR routing protocol. Experiments show that MORE-M's gains increase with the number of destinations, and are 35-200% greater than that of ExOR. …

Electrolyte Effects on the Kinetics of Comproportionation Electron-Transfer Reactions and on Intervalence Charge-Transfer Band Energies of Binuclear Ruthenium Ammine Complexes
… An increasing ratio of anion-catalyzed k<sub>etx</sub> to uncatalyzed k<sub>et</sub> is obtained when proceeding down the halide series. Activation parameters show a strong enthalpy-entropy compensation effect according to the identity of the added halide. Interestingly, the enthalpy …

A multi-lineage in vitro mouse embryo model derived exclusively from mouse embryonic stem cells
… endoderm stem cells (XEN cells)) in ETX embryos (embryo model composed of ESCs, TSCs and XEN cells) and iETX embryos (embryo model composed of ESCs, TSCs and induced XEN cells). While these integrated models have demonstrated greater developmental potentials, one remaining …
