TL;DR: In this article, it was shown that the Hamiltonian is a constant of motion for large population sizes and finite size effects break the temporal symmetry and induce a power-law decay of the Hamiltonians near the outbreak onset, with a parameter-free exponent.
Abstract: Empirical records of epidemics reveal that fluctuations are important factors for the spread and prevalence of infectious diseases. The exact manner in which fluctuations affect spreading dynamics remains poorly known. Recent analytical and numerical studies have demonstrated that improved differential equations for mean and variance of infected individuals reproduce certain regimes of the SIS epidemic model. Here, we show they form a dynamical system that follows Hamilton’s equations, which allow us to understand the role of fluctuations and their effects on epidemics. Our findings show the Hamiltonian is a constant of motion for large population sizes. For small populations, finite size effects break the temporal symmetry and induce a power-law decay of the Hamiltonian near the outbreak onset, with a parameter-free exponent. Away from the onset, the Hamiltonian decays exponentially according to a constant relaxation time, which we propose as a metric when fluctuations cannot be neglected.

TL;DR: The changing pattern of developing cuticle and associated epidermis is described during the imaginal molt in the honey bee, and histological analyses of the integument during apolysis and the subsequent deposition and differentiation of the adult cuticle provide insights that permit an improved physiological characterization for staging pupal and pharate adult development.
Abstract: The changing pattern of developing cuticle and associated epidermis is described during the imaginal molt in the honey bee. Observations began immediately after the pupal molt, and included histological analyses of the integument during apolysis and the subsequent deposition and differentiation of the adult cuticle. Apolysis coincides with a marked increase in the thickness and reorganization of the epidermal layer, reflecting changes in cell structure. The epidermis remains thickened during the period of cuticle deposition, suggesting intense biosynthetic activity, but turns into a very thin layer during cuticle differentiation, clearly indicating that secretory activity for cuticle formation is terminating. The thoracic cuticle differentiates earlier and becomes thicker than the abdominal. The observed changes in integument structure provide insights that permit an improved physiological characterization for staging pupal and pharate adult development.

TL;DR: The recombinant phytase showed maximum activity at 50°C, a half-life of 40min, and farUVCD spectroscopy indicated a secondary structure rich in α-helix, and thermal denaturation analyses reveal the melting temperature varied from 50° C at pH 6 to a maximum of 66°C at pH 3 and pH 4.
