New Quantum Effect: Emission of Cosmic X– or γ–rays by Moving Unstable Particles at Late Times

open access: yesEPJ Web of Conferences, 2016
A quantum effect induced by the late time properties of decaying states is discussed and its possible observational consequences are analyzed. It is shown that charged unstable particles as well as neutral unstable particles with non–zero magnetic moment

On the Communication Trifecta: Valuating – Emotions – Expression

open access: yesAnnales Universitatis Mariae Curie-Skłodowska. Sectio N, Educatio Nova, 2018
This paper evaluates the communication trifecta that consists of a series of consecutive elements: valuating, emotions, expression. These components, although relatively unstable, coexist in various configurations and many processes of interpersonal ...

Control based bifurcation analysis for experiments [PDF]

open access: yes, 2008
We introduce a method for tracking nonlinear oscillations and their bifurcations in nonlinear dynamical systems. Our method does not require a mathematical model of the dynamical system nor the ability to set its initial conditions.

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

open access: yesFEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

EFFECT OF DIAZEPAM TREATMENT ON THE COMPETITIVE BEHAVIOR OF MALE RATS AND ASSESSMENT OF ANXIETY IN COMPETING RATS

open access: yesZagazig Journal of Pharmaceutical Sciences, 2008
The current study was carried out to investigate the effect of diazepam treatment on the competitive behavior of male rats and assess the level of anxiety in the competing rats.

Resistance to change of responding maintained by unsignaled delays to reinforcement: a response-bout analysis.

open access: yes, 2006
Previous experiments have shown that unsignaled delayed reinforcement decreases response rates and resistance to change. However, the effects of different delays to reinforcement on underlying response structure have not been investigated in conjunction ...

New dispersed-dot halftoning technique by elimination of unstable pixels for electrophotography [PDF]

open access: yes, 2005
Printing processes of electrophotography basically involve some unstableness of analog nature. These instabilities make small dot reproduction stochastic and degrade image quality.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Resistance to change and frequency of response-dependent stimuli uncorrelated with reinforcement.

open access: yes, 2009
Stimuli uncorrelated with reinforcement have been shown to enhance response rates and resistance to disruption; however, the effects of different rates of stimulus presentations have not been assessed.
