Distributed Drives Monitoring and Control: A Laboratory Setup

open access: yesJournal of Engineering, 2013
A laboratory setup of distributed drives system comprising a three-phase induction motor (IM) drive and a permanent magnet synchronous motor (PMSM) drive is modeled, designed, and developed for the monitoring and control of the individual drives.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

DTC of a 5-Level MMC Fed 3-Φ Induction Motor with PI and FLC Using CBAPOD PWM Technique

open access: yesITEGAM-JETIA
Industrial motor drives, particularly three phase induction motor drives, have been adopting Modular Multilevel Converters (MMC). MMC is utilized in the design of power and control circuits to give the appropriate switching sequences that yield the ...

Surface Induction Motor for Two-dimensional Drive

open access: yesIEEJ Transactions on Industry Applications, 1998
In this paper, the authors propose an induction type surface or planar motor for smooth two-dimensional drive including rotating operation. The secondary member is composed of the flat conducting plate without directional qualities and the back-iron plate as secondary yoke.

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Braking Scheme for Vector-Controlled Induction Motor Drives Equipped With Diode Rectifier Without Braking Resistor [PDF]

open access: yes, 2006
This paper deals with sensorless vector control of PWM-inverter-fed induction motor drives equipped with a three-phase diode rectifier. An electronically controlled braking resistor across the dc link is not used.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.
