Estimation of characteristics of supported object on vibration isolator using air suspensions

open access: yesNihon Kikai Gakkai ronbunshu
An air suspension is one of the fundamental components of a vibration isolator that utilizes a stiffness caused by compressibility of air and damping effect caused by viscosity of air.

Experimental determination of the principal moments of inertia of the Helios prototype spacecraft [PDF]

open access: yes
The moment of inertia of the Helios Spacecraft about its spin axis was determined by use of a roll-fixture using two sets of crossed flexure pivots as elastic constraints.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

open access: yesFEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Problems of rotational mass in passenger vehicles [PDF]

open access: yesTransport Problems, 2010
This study presents an overview of methods for calculation of inertia mass in vehicles which impact on inertial resistance. Different opinions in references on rotational mass (engine with clutch mechanism and the road wheels) provided the author an ...

Anchorage‐independent and faster growth in clonal population from UV‐irradiated NER‐deficient cells

open access: yesFEBS Open Bio, EarlyView.
UV‐irradiated cells expressing a DDB2 mutant protein unable to interact with PCNA (DDB2PCNA‐) form clones able to grow without anchorage. Different experimental approaches reveal heterogeneity in cell cycle regulation and drug response within these clones, emphasizing the crucial role of the DDB2‐PCNA interaction in preventing cellular transformation ...
