Hypersensitivity to Perturbations in the Quantum Baker's Map [PDF]
Phys. Rev. Lett. 71, 525 (1993), 1993 We analyze a randomly perturbed quantum version of the baker's transformation, a prototype of an area-conserving chaotic map. By numerically simulating the perturbed evolution, we estimate the information needed to follow a perturbed Hilbert-space vector in time. We find that the Landauer erasure cost associated with this information grows very rapidly

Hypersensitivity and chaos signatures in the quantum baker's maps [PDF]
J. Phys. A 39, 13405 (2006), 2006 Classical chaotic systems are distinguished by their sensitive dependence on initial conditions. The absence of this property in quantum systems has lead to a number of proposals for perturbation-based characterizations of quantum chaos, including linear growth of entropy, exponential decay of fidelity, and hypersensitivity to perturbation.

An Updated Review of the Molecular Mechanisms in Drug Hypersensitivity
Journal of Immunology Research, 2018 Drug hypersensitivity may manifest ranging from milder skin reactions (e.g., maculopapular exanthema and urticaria) to severe systemic reactions, such as anaphylaxis, drug reactions with eosinophilia and systemic symptoms (DRESS)/drug-induced ...

Chaos for Liouville probability densities [PDF]
, 1995 Using the method of symbolic dynamics, we show that a large class of classical chaotic maps exhibit exponential hypersensitivity to perturbation, i.e., a rapid increase with time of the information needed to describe the perturbed time evolution of the Liouville density, the information attaining values that are exponentially larger than the entropy ...

Age Differences in Pet Sensitization by Pet Ownership [PDF]
Clinical and Experimental Otorhinolaryngology, 2021 Objectives The association between pet sensitization and pet ownership remains unclear. Therefore, we aimed to elucidate the association between pet sensitization and pet ownership by age.

Cough hypersensitivity and chronic cough
Nature Reviews Disease Primers, 2022 Chronic cough is globally prevalent across all age groups. This disorder is challenging to treat because many pulmonary and extrapulmonary conditions can present with chronic cough, and cough can also be present without any identifiable underlying cause ...

Innate immune deficiencies are associated with severity and poor prognosis in patients with COVID-19
Scientific Reports, 2022 COVID-19 can cause acute respiratory distress syndrome, leading to death in many individuals. Evidence of a deleterious role of the innate immune system is accumulating, but the precise mechanisms involved remain unclear.

The Roles of Immunoregulatory Networks in Severe Drug Hypersensitivity
Frontiers in Immunology, 2021 The immunomodulatory effects of regulatory T cells (Tregs) and co-signaling receptors have gained much attention, as they help balance immunogenic and immunotolerant responses that may be disrupted in autoimmune and infectious diseases.
