Interval voting technique for active and dormant state synchronization of the nodes in WSN [PDF]

, 2015
Energy conservation is one of the main issues of WSN research. To save energy and prolong sensor nodes lives, nodes operate in a duty-cycling work mode.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

A Receiver-Initiated MAC Protocol for Wireless Sensor Networks Based on Tree Topology

International Journal of Distributed Sensor Networks, 2015
This paper proposes receiver-initiated X-MAC with tree topology (TRIX-MAC), an improved energy-efficient MAC protocol based on an asynchronous duty cycling for wireless sensor networks with tree topology.

Portability, compatibility and reuse of MAC protocols across different IoT radio platforms [PDF]

, 2019
To cope with the diversity of Internet of Things (loT) requirements, a large number of Medium Access Control (MAC) protocols have been proposed in scientific literature, many of which are designed for specific application domains.

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Failure mechanisms of single-crystal silicon electrodes in lithium-ion batteries

Nature Communications, 2016
Long-term durability is crucial for heavy-duty usage of lithium ion batteries; however, electrode failure mechanisms are still unknown. Here, the authors reveal the fracture mechanisms of single crystal silicon electrodes over extended cycling, and show ...

Motorless cadence control of standard and low duty cycle-patterned neural stimulation intensity extends muscle-driven cycling output after paralysis

Journal of NeuroEngineering and Rehabilitation, 2022
Background Stimulation-driven exercise is often limited by rapid fatigue of the activated muscles. Selective neural stimulation patterns that decrease activated fiber overlap and/or duty cycle improve cycling exercise duration and intensity.

Poster Abstract: Interconnecting Low-Power Wireless and Power-Line Communications using IPv6 [PDF]

, 2010
Wireless sensor networks for building automation and energy management has made great progress in recent years, but the inherent indoor radio range limitations can make communication unpredictable and system deployments difficult.

Inspiratory muscle training reduces blood lactate concentration during volitional hyperpnoea [PDF]

, 2008
Although reduced blood lactate concentrations ([lac−]B) have been observed during whole-body exercise following inspiratory muscle training (IMT), it remains unknown whether the inspiratory muscles are the source of at least part of this reduction.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
