Mono-objective optimization with design constraints of the mechanical systems using ADAMS [PDF]

Journal of Research and Innovation for Sustainable Society
The paper addresses the mono-objective optimization with design constraints of mechanical systems using the virtual prototyping software environment ADAMS. The optimization problem is formulated as follows: finding the optimal values of the independent

Tear resistance of soft collagenous tissues

Nature Communications, 2019
Defect tolerance is important in order to ensure the mechanical integrity of synthetic materials and biological tissues. Here the authors demonstrate that toughening mechanisms provide soft collagenous tissues with high defect tolerance, with important ...

Stable voltage-controlled charge source circuit against capacitive loads and its application to synthetic admittance for piezoelectric shunt damping

Nihon Kikai Gakkai ronbunshu, 2018
This paper proposes a novel controlled charge source circuit for synthetic admittance of piezoelectric shunt damping system. A design method for the proposed charge source circuit is also proposed.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Change in Surface Tension and Pin Wear Characteristics of Thin-Film Disks by Heat Treatment and UV Irradiation

Tribology Online, 2010
The lubricant on thin-film disks is a key material for disk durability. Bonded lubricant layer remains on disk surfaces after solvent rinsing which removes mobile lubricant.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Experimental study on onset turbulence in a flat-plate boundary layer

Journal of Fluid Science and Technology, 2019
A wind tunnel experiment was performed to investigate the suitable conditions in which a localized turbulent region can easily be generated in a flat-plate boundary layer.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
