Time Curves: Folding Time to Visualize Patterns of Temporal Evolution in Data

Benjamin Bach, Conglei Shi, Nicolas Heulot, Tara Madhyastha, Tom Grabowski, Pierre Dragicevic
2016 IEEE Transactions on Visualization and Computer Graphics  
Time curves are not meant to replace domain-specific temporal visualizations, as in many cases such visualizations may be required for a deeper examination of the data once interesting patterns have been  ...  Thus we need to develop more visual representations of temporal data that can be applied to a range of datasets.  ...

Time-reversed Gamma-Ray Burst Light-curve Characteristics as Transitions between Subluminal and Superluminal Motion

Jon Hakkila, Robert Nemiroff
2019 Astrophysical Journal  
We introduce a simple model to explain the time-reversed and stretched residuals in gamma-ray burst (GRB) pulse light curves.  ...  These transitions create both a time-forward and a time-reversed set of light curve features through the process of Relativistic Image Doubling (RID).  ...  We express our gratitude to Tim Giblin, Rob Preece, Amy Lien, and Narayanan Kuthirummal for their many patient discussions and valuable contributions to this manuscript during its development.  ...

Functional modelling of microarray time series with covariate curves [article]

Maurice Berk, Giovanni Montana
2011 arXiv   pre-print
In this paper we have demonstrated a complete framework for the analysis of microarray time series data.  ...  The unique characteristics of microarry data lend themselves well to a functional data analysis approach and we have shown how this naturally extends to the inclusion of covariates such as age and sex.  ...  We also show how a functional PCA can be applied to the estimated mean curves in order to identify the principal modes of functional variation in the data set, and visually represent the entire set of  ...

Time Matters

Bo Wu, Wen-Huang Cheng, Yongdong Zhang, Tao Mei
2016 Proceedings of the 2016 ACM on Multimedia Conference - MM '16  
The evolution of social media popularity exhibits rich temporality, i.e., popularities change over time at various levels of temporal granularity.  ...  As a result, our approach can leverage multiple levels of temporal characteristics and reduce the noise of data decomposition to improve modeling effectiveness.  ...  The first category builds popularity models to discover general patterns for temporal trends in popularity data [10, 11, 12, 13, 14, 15] .  ...

Real-time kinetics and high-resolution melt curves in single-molecule digital LAMP to differentiate and study specific and non-specific amplification

2020 Nucleic Acids Research  
We use real-time dLAMP with HRM to evaluate differences between polymerase enzymes, the impact of assay parameters (e.g. time, rate or florescence intensity), and the effect background human DNA.  ...  By differentiating true and false positives, HRM enables determination of the optimal assay and analysis parameters that leads to the lowest limit of detection (LOD) in a digital isothermal amplification  ...  Conflict of interest statement.

Dispersive and dissipative effects in quantum field theory in curved space-time to model condensed matter systems [article]

Xavier Busch
2014 arXiv   pre-print
The two main predictions of quantum field theory in curved space-time, namely Hawking radiation and cosmological pair production, have not been directly tested and involve ultra high energy configurations  ...  In this thesis, we first analyze the effects of dispersion and dissipation on both Hawking radiation and pair particle production. To get explicit results, we work in the context of de Sitter space.  ...  I thank them and every researcher with whom I had long discussions for the time they gave me. I also thank the jury of this PhD for the interest they show in my work.  ...

Deep Attention-Based Supernovae Classification of Multi-Band Light-Curves [article]

Óscar Pimentel, Pablo A. Estévez, Francisco Förster
2022 arXiv   pre-print
Along with this scarcity, the processing of multi-band light-curves is a challenging task due to the highly irregular cadence, long time gaps, missing-values, low number of observations, etc.  ...  This allows us to increase the number of samples and the diversity of the cadence. The TimeModAttn model is first pre-trained using synthetic light-curves in a semi-supervised learning scheme.  ...  ACKNOWLEDGMENTS The authors acknowledge support from the National Agency of Research and Development's Millennium Science Initiative through grant IC12009, awarded to the Millennium Institute of Astrophysics  ...

Heterochronic evolution reveals modular timing changes in budding yeast transcriptomes

Daniel F Simola, Chantal Francis, Paul D Sniegowski, Junhyong Kim
2010 Genome Biology  
Here, we examined transcriptome evolution in the dynamical context of the budding yeast cell-division cycle, to investigate the extent of divergence in expression timing and the regulatory architecture  ...  Analysis of shared patterns of timing evolution suggests the existence of seven dynamically-autonomous modules, each of which shows coherent evolutionary timing changes.  ...  The funding bodies had no role in study design; in collection, analysis, or interpretation of data; in the writing of the manuscript; or in the decision to submit the manuscript for publication.  ...

Continuous Functional Magnetic Resonance Imaging Reveals Dynamic Nonlinearities of "Dose-Response" Curves for Finger Opposition

Gregory S. Berns, Allen W. Song, Hui Mao
1999 Journal of Neuroscience  
When the time courses of the task-related components were plotted against tapping frequency, nonlinear "doseresponse" curves were obtained for most subjects.  ...  To test these assumptions, we performed a continuous functional magnetic resonance imaging (MRI) experiment of finger opposition. Subjects performed a visually paced bimanual fingertapping task.  ...  Using finger tapping as a test of several new techniques, we have begun to identify the temporal evolution of spatial patterns of activity and how these correlate with at least one behavioral parameter  ...
