On a Classical Theta-Function [PDF]

open access: yesNagoya Mathematical Journal, 1970
The purpose of this paper is to get a certain explicit expression of automorphic factors, formulated rather differently than usual, of the classically well known theta function(1)

Developmental Changes in Hippocampal CA1 Single Neuron Firing and Theta Activity during Associative Learning. [PDF]

open access: yesPLoS ONE, 2016
Hippocampal development is thought to play a crucial role in the emergence of many forms of learning and memory, but ontogenetic changes in hippocampal activity during learning have not been examined thoroughly.

Ramanujan’s mock theta functions [PDF]

open access: yesProceedings of the National Academy of Sciences, 2013
In his famous deathbed letter, Ramanujan introduced the notion of a mock theta function , and he offered some alleged examples. Recent work by Zwegers [Zwegers S (2001) Contemp Math 291:268–277 and Zwegers S (2002) PhD thesis (Univ of Utrecht, Utrecht ...

Phase-locked closed-loop ultrasound stimulation modulates theta and gamma rhythms in the mouse hippocampus

open access: yesFrontiers in Neuroscience, 2022
Previous studies have demonstrated that open-loop transcranial ultrasound stimulation (TUS) can modulate theta and gamma rhythms of the local field potentials (LFPs) in the mouse hippocampus; however, the manner in which closed-loop TUS with different ...

Increased mesiotemporal delta activity characterizes virtual navigation in humans [PDF]

open access: yes, 2013
Hippocampal theta or rhythmic slow activity (RSA) occurring during exploratory behaviors and rapid-eye-movement (REM) sleep is a characteristic and well-identifiable oscillatory rhythm in animals.

Entropy solutions to parabolic equations in Musielak framework involving non coercivity term in divergence form [PDF]

open access: yesMathematica Bohemica, 2018
We prove the existence of solutions to nonlinear parabolic problems of the following type: \begin{cases} \dfrac{\partial b(u)}{\partial t}+ A(u) = f + {\rm div}(\Theta(x; t; u))& \text{in} Q, u(x; t) = 0 & \text{on} \partial\Omega\times[0; T], b(u)

Computing Riemann theta functions [PDF]

open access: yesMathematics of Computation, 2003
The Riemann theta function is a complex-valued function of g complex variables. It appears in the construction of many (quasi-) periodic solutions of various equations of mathematical physics. In this paper, algorithms for its computation are given.

EESTIMATES OF BEST APPROXIMATIONS OF FUNCTIONS WITH LOGARITHMIC SMOOTHNESS IN THE LORENTZ SPACE WITH ANISOTROPIC NORM

open access: yesUral Mathematical Journal, 2020
In this paper, we consider the anisotropic Lorentz space \(L_{\bar{p}, \bar\theta}^{*}(\mathbb{I}^{m})\) of periodic functions of \(m\) variables. The Besov space \(B_{\bar{p}, \bar\theta}^{(0, \alpha, \tau)}\) of functions with logarithmic smoothness is

Efficacy and safety of intermittent theta-burst stimulation in patients with schizophrenia: A meta-analysis of randomized sham-controlled trials

open access: yesFrontiers in Pharmacology, 2022
Theta-burst stimulation is a non-invasive brain stimulation technique that was introduced as a potential augmentation treatment for patients with schizophrenia.
