Collective Oscillations in coupled cell systems

B305 Seminar room, IBS 55 Expo-ro Yuseong-gu, Daejoen

We will discuss about "Collective Oscillations in coupled cell systems", Chen and Sinh, Bulletin of Mathematical Biology, 2021 We investigate oscillations in coupled systems. The methodology is based on the Hopf bifurcation theorem and a condition extended from the Routh–Hurwitz criterion. Such a condition leads to locating the bifurcation values of the parameters. With such

Deciphering circadian clock cell network morphology within the biological master clock, the suprachiasmatic nucleus

B305 Seminar room, IBS 55 Expo-ro Yuseong-gu, Daejoen

Abstract: The biological master clock, the suprachiasmatic nucleus (SCN) of a mouse, contains many (~20,000) clock cells heterogeneous, particularly with respect to their circadian period. Despite the inhomogeneity, within an intact SCN, they maintain a very high degree of circadian phase coherence, which is generally rendered visible as system-wide propagating phase waves. The phase coherence

Statistical Inference with Neural Network Imputation for Item Nonresponse

B305 Seminar room, IBS 55 Expo-ro Yuseong-gu, Daejoen

Abstract: We consider the problem of nonparametric imputation using neural network models. Neural network models can capture complex nonlinear trends and interaction effects, making it a powerful tool for predicting missing values under minimum assumptions on the missingness mechanism. Statistical inference with neural network imputation, including variance estimation, is challenging because the basis for function

Inference for Circadian Pacemaking

ZOOM ID: 709 120 4849 (ibsbimag)

This talk will be presented online. Zoom link: 709 120 4849 (pw: 1234) Abstract: Organisms have evolved an internal biological clock which allows them to temporally regulate and organize their physiological and behavioral responses to cope in an optimal way with the fundamentally periodic nature of the environment. It is now well established that the

Stochastic processes as scientific instruments: efficient inference based on stochastic dynamical systems

ZOOM ID: 709 120 4849 (ibsbimag)

This talk will be presented online. Zoom link: 709 120 4849 (pw: 1234) Abstract: Questions about the mechanistic operation of biological systems are naturally formulated as stochastic processes, but confronting such models with data can be challenging.  In this talk, I describe the essence of the difficulty, highlighting both the technical issues and the importance
