Exponential Decay and Fermi's Golden Rule from an Uncontrolled Quantum Zeno Effect [PDF]
, 2014 We modify the theory of the Quantum Zeno Effect to make it consistent with the postulates of quantum mechanics. This modification allows one, throughout a sequence of observations of an excited system, to address the nature of the observable and thereby ...

Perturbative Strong Interaction Corrections to the Heavy Quark Semileptonic Decay Rate [PDF]
, 1994 We calculate the part of the order $\alpha_s^2$ correction to the semileptonic heavy quark decay rate proportional to the number of light quark flavors, and use our result to set the scale for evaluating the strong coupling in the order $\alpha_s$ term ...

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Tennyson’s Wrinkled Feet: Ageing and the Poetics of Decay
19, 2021 This article argues that Tennyson’s ‘Tithonus’ (1860) draws together ageing and decay through the poem’s formal wrinkling: moments where metrical disruption, folding, slackness, or concealment correspond to the insights derived from the perspective of ...

, 2002 The motivation, present status, and future plans of the search for the neutrinoless double beta decay are reviewed. It is argued that, motivated by the recent observations of neutrino oscillations, there is a reasonable hope that neutrinoless double beta

FEBS Open Bio, EarlyView.A regulatory axis involving APE1, AUF1, and miR‐221 is proposed. Pri‐miR‐221 is processed by DROSHA and DICER to generate mature miR‐221, which targets p27Kip1 mRNA. APE1 and AUF1 compete for pre‐miR‐221 binding. Reduced APE1/AUF1 levels impair miR‐221 biogenesis, decrease p27Kip1 mRNA degradation, and promote cell cycle progression, chemoresistance ...

Diffusion of gases dissolved in peat pore water [PDF]
Mires and Peat, 2012 Diffusion is usually thought to be ineffective at transporting solutes over distances of several metres – the depth of many peat deposits. But this is to neglect the importance of time. We derive equations that show that in peat that has accumulated over

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
