Stretching and Bending Fluctuations of Short DNA Molecules [PDF]
Biophysical Journal, 2013 Recent measurements of the distribution of end-to-end distance in short DNA molecules infer cooperative stretching fluctuations. The assumptions underlying the analysis can be questioned if transient, thermally induced defects producing a localized ...

Short-term Fluctuations and Fluctuations in the Development Dynamics of Fixed Assets of Industry
Management and Production Engineering Review, 2023 The purpose of the article is to create a concise nonlinear mathematical model for analyzing the growth of fixed assets in a specific industry. The emergence of chaotic behaviour in economic systems was explored, focusing on fluctuations.

On the Validity of Detrended Fluctuation Analysis at Short Scales [PDF]
Entropy, 2021 Detrended Fluctuation Analysis (DFA) has become a standard method to quantify the correlations and scaling properties of real-world complex time series. For a given scale ℓ of observation, DFA provides the function F(ℓ), which quantifies the fluctuations of the time series around the local trend, which is substracted (detrended).

Optimism, pessimism, and short-term fluctuations [PDF]
Journal of Macroeconomics, 2018 Abstract Economic theory offers several explanations as to why shifting expectations about future economic activity affect current demand. Abstracting from whether changes in expectations originate from swings in beliefs or fundamentals, we test empirically whether optimism and pessimism about the economy trigger short-term fluctuations in private ...

The hydrophobic effect, and fluctuations: The long and the short of it [PDF]
Proceedings of the National Academy of Sciences, 2016 The hydrophobic effect, which is used to describe the aversion of oil for water or the affinity of oily objects for one another in water, plays an important role in diverse disciplines (1). For example, by segregating to the oil–water interface, amphiphilic molecules that possess both hydrophobic and hydrophilic groups can mitigate unfavorable oil ...

Evaluation of short-term epigenetic age fluctuation
Clinical Epigenetics, 2022 AbstractConsiderable effort has been spent on lowering and maintaining the epigenetic age. However, the extent to which epigenetic age fluctuates under normal conditions is poorly understood. Therefore, we analyzed methylation data from monocytes and peripheral blood mononuclear cells collected from two Japanese men.

Dealing With Short-term Fluctuation in Longitudinal Research [PDF]
The Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 2010 Many analytical methods are not very sensitive to change because of the difficulty of distinguishing short-term fluctuation from the developmental change of primary interest. The current project investigated one possible solution to this problem in the form of a measurement-burst design in which research participants perform several versions of each ...

Visual detection of short-wave blood pressure fluctuations
Proceedings of the 16th International Conference on PErvasive Technologies Related to Assistive Environments, 2023 Blood pressure provides important information about a person’s state of health. It changes greatly during physical activity, but blood pressure at rest also indicates abnormal or pathological conditions. However, periodic fluctuations in blood pressure are also superimposed on blood pressure, which have so far been difficult to measure and thus remain ...
