Dynamics of a Predator-Prey Model with Fear Effect and Time Delay by Junli Liu, Pan Lv, Bairu Liu, Tailei Zhang

“…We found that there are stability switches, and Hopf bifurcations occur when the delay τ passes through a sequence of critical values. The explicit formulae which determine the direction, stability, and other properties of the bifurcating periodic solutions are given by using the normal form theory and center manifold theorem. …”

Predefined-Time Antisynchronization of Two Different Chaotic Neural Networks by Lixiong Lin

“…Firstly, a predefined-time stability theorem based on Lyapunov function is proposed. With the help of the definition of predefined time, it is convenient to establish a direct relationship between the tuning gain of the system and the fixed stabilization time. …”

Global analysis of CP $$ \mathcal{CP} $$ -violation in atoms, molecules and role of medium-heavy systems by Konstantin Gaul, Robert Berger

“…The model is confirmed by explicit density functional theory calculations of all relevant P $$ \mathcal{P} $$ , T $$ \mathcal{T} $$ -odd electronic structure parameters in systems that were used in past experiments or are of current interest for future experiments, respectively: the atoms Xe, Cs, Yb, Hg, Tl, Ra, Fr and the molecules CaOH, SrOH, YO, CdH, BaF, YbF, YbOH, HfF+, WC, TlF, PbO, RaF, ThO, ThF+ and PaF3+.…”

فقه المصائب والبلايا : (نظرات وحكم في تمكين الأمة وتنظيمها على ضوء النصوص الشرعية) by Abdul Mukti Thabrani

“…This writing is trying to describe deeply and dig about the Fiqh of disasters, in the context of reading the implicit or explicit theorems, as the base and reference in seeing the God’s rule on Earth and as the form of implementation of our believing to the faith that can be done with maximum effort to be a good human being who realizes his function as Khalifah. …”

Periodic solutions for a class of perturbed sixth-order autonomous differential equations by Chems Eddine Berrehail, Amar Makhlouf

“…Originality/value – The authors studied Equation 1 which depends explicitly on the independent variable t. Here, the authors studied the autonomous case using a different approach.…”

Geometric Sensitivity of a Pinhole Collimator by Howard Jacobowitz, Scott D. Metzler

“…This is done by converting the integral to an integral in the complex plane and using Cauchy's theorem to replace it by one which can be evaluated in terms of elliptic functions.…”

Dirichlet type extensions of Euler sums by Xu, Ce, Wang, Weiping

“…In this paper, we study the alternating Euler $T$-sums and $\tilde{S}$-sums, which are infinite series involving (alternating) odd harmonic numbers, and have similar forms and close relations to the Dirichlet beta functions. By using the method of residue computations, we establish the explicit formulas for the (alternating) linear and quadratic Euler $T$-sums and $\tilde{S}$-sums, from which, the parity theorems of Hoffman’s double and triple $t$-values and Kaneko–Tsumura’s double and triple $T$-values are further obtained. …”
