This study examines the role of periodic information, the mechanism of influence, stochastic resonance, and its controllable analysis in complex corporate financial systems. A stochastic predator-prey complex corporate financial system model driven by periodic information is proposed. Additionally, we introduce signal power amplification to quantify the stochastic resonance phenomenon and develop a method for analyzing stochastic resonance in financial predator-prey dynamics within complex corporate financial systems. We optimize a simplified integral calculation method to enhance the proposed model's performance, which demonstrates superiority over benchmark models based on empirical evidence. Based on stochastic simulations and numerical calculations, we can observe multiple stochastic and multiple inverse stochastic resonances. Furthermore, variations in initial financial information, periodic information frequency, and corporate growth capacity induced stochastic resonance and inverse stochastic resonance. These variations also led to state transitions between the two resonance behaviors, indicating transition phenomena. These findings suggest the potential for regulating and controlling stochastic and inverse stochastic resonance in complex corporate finance, enabling controllable stochastic resonance behaviors.

We reveal contrasting behaviors in molecular motion between the two materials, including the identification of resonance-enhanced dynamic features in elastomers. We present a depth-resolved analysis of molecular dynamics in semicrystalline polytetrafluoroethylene (PTFE) and fully amorphous fluorinated elastomer (SIFEL) films using static-gradient solid-state F NMR imaging. By measuring spin-lattice relaxation rates ( ) at multiple frequencies and evaluating the corresponding spectral density functions, we reveal distinct dynamic behaviors between the two materials.

Water-ion interactions govern the physicochemical properties of aqueous solutions, impacting the structure of the hydrogen bonding network and ion diffusivities. To elucidate these effects under alkaline conditions relevant to diverse application spaces, we examined NaOD-DO solutions using two-dimensional infrared spectroscopy (2D-IR), small-angle X-ray scattering (SAXS), and nuclear magnetic resonance spectroscopy (NMR). Vibrational energy transfer between the donor anion SeCN, used as a 2D-IR probe, and the acceptor anion OD was used to track the average separation distance of ions in the DO solutions, while SAXS and NMR experiments measured the structure of the bulk DO solvent.

We demonstrate that nonlocal coupling enables control of the collective stochastic dynamics in the regime of coherence resonance. The control scheme based on the nonlocal interaction properties is presented by means of numerical simulation on an example of coupled FitzHugh-Nagumo oscillators. In particular, increasing the coupling radius is shown to enhance or to suppress the effect of coherence resonance, which is reflected in the evolution of the dependence of the correlation time and the deviation of interspike intervals on the noise intensity.

Background: Low back pain (LBP) is the leading cause of disability worldwide. Up to half of moderate-to-severe acute LBP (aLBP) progress to chronic (cLBP), with neuromotor, fascial, and muscle pathology contributing to inoperable mechanical disability. A novel thermomechanical stimulation (M-Stim) device delivering stochastic and targeted vibration frequencies relieved LBP in a pilot.

Pacemaker myocytes of the sinoatrial (SA) node initiate each heartbeat through coupled voltage and Ca oscillators, but whether ATP supply is regulated on a beat-by-beat schedule in these cells has been unclear. Using genetically encoded sensors targeted to the cytosol and mitochondria, we tracked beat-resolved ATP dynamics in intact mouse SA node and isolated myocytes. Cytosolic ATP rose transiently with each Ca transient and segregated into high- and low-gain phenotypes defined by the Ca-ATP coupling slope.
