Classical canard explosion results in smooth systems require the vector field to be at least C, since canard cycles are created as the result of a Hopf bifurcation. The work on canards in nonsmooth, planar systems is recent and has thus far been restricted to piecewise-linear or piecewise-smooth Van der Pol systems, where an extremum of the critical manifold arises from the nonsmoothness. In bo...

The back action of typical macroscopic resonators used for detecting nuclear magnetic resonance can cause a reversible decay of the signal, known as radiation damping. A mechanical resonator that is strongly coupled to a microscopic sample can in addition induce an irreversible dissipation of the nuclear-spin signal, distinct from radiation damping. We provide a theoretical description of reson...

the relationship between relaxation and rhythmic exercises with regard to functional neuroplasticity mechanism is a subject that has been studied in recent researches. the purpose of this study was to investigate the effect of rhythmic exercises on the depth of relaxation in national judo athletes. 30 male athletes of national judo team were randomly selected and divided into three groups: cont...

The phenomenon of relaxation and oscillation is a common event that often encountered. Both these properties can occur in viscoelastic materials even though they do not simultaneously. Because the characteristics are difficult to describe using classical-order differential equations, this study, fractional-order equations were used model each phenomena with help Laplace transform as solution me...

Despite being the most abundant (by space density) of interacting binary stars, W Ursae Majoris (W UMa) stars are not understood structurally. Their stellar components are in physical contact, and share a common convective envelope. Observations demand large-scale energy exchange between components, as do considerations of hydrostatic and thermal equilibrium. Yet solutions in complete equilibri...

Following the recent convincing evidence for neutrino oscillations, leptogenesis has become a well motivated possible explanation of the origin of the baryon asymmetry of the universe. In these proceedings, after a short introduction on the three basic ingredients of leptogenesis, we will extend the discussion of Ref. along two main directions. First, in the framework of the usual seesaw model ...

This study compared clicker technology against mobile polling and the Just-in-Time Teaching (JiTT) strategy to investigate how these methods may differently affect students’ anxiety, self-efficacy, engagement, academic performance, and attention and relaxation as indicated by brainwave activity. The study utilized a quasi-experimental research design. To assess the differences between the effec...

We study analytically and numerically a generic continuum model of an isotropic active solid with internal stresses generated by non-equilibrium ‘active’ mechano-chemical reactions. Our analysis shows that the gel can be tuned through three classes of dynamical states by increasing motor activity: a constant unstrained state of homogeneous density, a state where the local density exhibits susta...
