In this work, we studied the complex behaviors of fractional-order financial chaotic system, consisting a simple, relatively system with two quadratic nonlinearities (QN) and sextic nonlinearity (SN). We completed enriched results presented in study Subartini et al. (2021). As result this, our focused more on fractional order adaptive finite-time sliding mode control risk system. The dynamical (FCS) QN an SN were analyzed, stability was investigated via Cardano method. analysis showed that real part all roots negative, which confirmed new under typical parameters. By using MATLAB simulation, these properties characterized, including phase portraits, 0-1 test, Poincaré map, bifurcation diagram, Lyapunov exponent. able to exhibit behavior periodical behavior. spite external perturbations uncertainty, strategy devised guide states origin finite amount time. plots employed illustrate main results.

Loneliness negatively impacts older adults' mental and physical health. Though loneliness is associated with perceived social support, its relationship to received support unclear. This might be because has been defined sparsely, overlooking types of overall quality. The current study addressed this gap. Older adults recruited from the community (N = 142) Indiana Alzheimer's Disease Research Center (ADRC) 176) completed an expanded PhenX network interview identify size, (emotional, instrumental), quality (network closeness, contact frequency). They also well-validated measures support. Data were analyzed hierarchical linear regressions. In both samples, was related but not either type. Contact frequency predicted in closeness ADRC sample only. Dementia status did affect results. Social emotional instrumental loneliness, were. These findings suggest that influenced by some
