Medium Spiny Neurons Mediate Timing Perception in Coordination with Prefrontal Neurons in Primates
Advanced Science, EarlyView.Timing perception is a crucial cognitive function enabling effective navigation in the environment, involving both prospective and retrospective timing. This study investigates the neural mechanisms in monkeys, uncovering distinct processes that shape temporal perception and highlighting the essential role of D2 medium spiny neurons in the striatum as ...

Astronomische Nachrichten, Volume 343, Issue 9-10, November-December 2022., 2022 Abstract The advent of ultra‐precise photometry space missions enables the possibility of investigating stellar interiors with mixed modes. The structural variations induced by the discontinuity of the chemical composition left behind during the first dredge–up is an important feature in the stellar mid‐layers located between the hydrogen‐burning shell

Some Asymptotic Behavior of the first Eigenvalue along the Ricci Flow [PDF]
arXiv, 2007 We study some asymptotic behavior of the first nonzero eigenvalue of the Lalacian along the normalized Ricci flow and give a direct short proof for an asymptotic upper limit estimate.

Minimal Riesz energy on balanced fractal sets [PDF]
arXiv, 2020 We investigate the asymptotic behavior of minimal $N$-point Riesz $s$-energy on fractal sets of non-integer dimension, with algebraically dependent contraction ratios. For $s$ bigger than the dimension of the set $A$, we prove the asymptotic behavior of the minimal $N$-point Riesz $s$-energy of $A$ along explicit subsequences, but we show that the ...

Asymptotic behavior of stable manifolds [PDF]
Proceedings of the American Mathematical Society, 1991 The relation between local stable manifolds of an ordinary differential equation and its discretization is studied. We show that a local stable manifold of a hyperbolic fixed point of an ordinary differential equation is the limit of local stable manifolds of the same fixed point of its discretizations as the discretization parameter h

Actionable Forecasting as a Determinant of Biological Adaptation
Advanced Science, EarlyView.A new framework reveals how biological systems can achieve precise adaptation by tracking an actionable target that combines the current optimal state with its rate of change. This approach, implemented through dynamics‐informed neural networks, demonstrates that predictive mechanisms like circadian rhythms become beneficial when environmental sensing ...

Asymptotics of Entropy Rate in Special Families of Hidden Markov Chains [PDF]
arXiv, 2008 We derive an asymptotic formula for entropy rate of a hidden Markov chain around a "weak Black Hole". We also discuss applications of the asymptotic formula to the asymptotic behaviors of certain channels.

Uncertainty principles and asymptotic behavior
Applied and Computational Harmonic Analysis, 2004 AbstractVarious uncertainty principles for univariate functions are studied, including classes of such principles not considered before. For many uncertainty principles for periodic functions, the lower bound on the uncertainty is not attained. By considering Riemann sums, we show that for functions whose Fourier coefficients are sampled from the ...
