Oscillation criteria for second order nonlinear neutral differential equations of mixed type
Electronic Journal of Qualitative Theory of Differential Equations, 2012 Some oscillation criteria are established for the second order nonlinear neutral differential equations of the form \begin{equation*} \left( \left( x(t)+a x(t-\tau_1)-b x(t+\tau_2)\right)^\alpha\right)''=q(t) x^\beta (t-\sigma_1)+p(t)x^\beta(t+\sigma_2)

Comparison theorem for oscillation of fourth-order nonlinear retarded dynamic equations
Electronic Journal of Qualitative Theory of Differential Equations, 2013 This work is concerned with oscillation of a class of fourth-order nonlinear delay dynamic equations on a time scale. A new comparison theorem is established that improves related results reported in the literature.

Oscillatory behavior of the second order noncanonical differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2019 Establishing monotonical properties of nonoscillatory solutions we introduce new oscillatory criteria for the second order noncanonical differential equation with delay/advanced argument \begin{equation*} (r(t)y'(t))'+p(t)y(\tau(t))=0. \end{equation*}

Fourth-Order Neutral Differential Equation: A Modified Approach to Optimizing Monotonic Properties
Mathematics, 2023 In this article, we investigate some qualitative properties of solutions to a class of functional differential equations with multi-delay. Using a modified approach, we first derive a number of optimized relations and inequalities that relate the ...

Antiperiodic oscillations [PDF]
Scientific Reports, 2013 The investigation of regular and irregular patterns in nonlinear oscillators is an outstanding problem in physics and in all natural sciences. In general, regularity is understood as tantamount to periodicity. However, there is now a flurry of works proving the existence of "antiperiodicity", an unfamiliar type of regularity.

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Set-Valued and Variational Analysis, 2017 In previous work by Beer and Levi [8, 9], the authors studied the oscillation $ (f,A)$ of a function $f$ between metric spaces $\langle X,d \rangle$ and $\langle Y, \rangle$ at a nonempty subset $A$ of $X$, defined so that when $A =\{x\}$, we get $ (f,\{x\}) = (f,x)$, where $ (f,x)$ denotes the classical notion of oscillation of $f$ at the point $
