Performance analysis of a tunable cost function based WLAN energy efficient packet transmission technique

open access: yes, 2014
This paper propose a new algorithm to adapt the transmission parameters of the IEEE 802.11 network devices to optimize the energy consumption of a WLAN transmitter under different Quality of Service (QoS) constraints.

Multi-Vector Model Predictive Control for Three-Phase Four-Switch Rectifier with Capacitor Voltage Balancing

open access: yesZhongguo dianli, 2019
Three-phase four-switch rectifier has the problem of unbalanced capacitor voltage because one phase of its AC side is directly connected between two capacitor neutral points on the DC side.

Regular Temporal Cost Functions [PDF]

open access: yes, 2010
Regular cost functions have been introduced recently as an extension to the notion of regular languages with counting capabilities. The specificity of cost functions is that exact values are not considered, but only estimated. In this paper, we study the strict subclass of regular temporal cost functions.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

A Simple and Robust Model Predictive Current Control of Induction Machine Using Stator Current Predictor and Target-Oriented Cost Function

open access: yesIEEE Access, 2021
Model predictive current control, which inherits from vector control framework, is expected to become a promising control strategy to improve the dynamic performance of servo system because of its simple structure and fast dynamic response.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
