Hastings Center Report, 2021 AbstractTwo articles in the March‐April 2021 issue of the Hastings Center Report consider alterations to traditional informed consent. In “The Consent Continuum: A New Model of Consent, Assent, and Nondissent for Primary Care,” Marc Tunzi and colleagues argue that, in primary care settings, patient consent should be understood as taking a range of ...

Early Universe Constraints on Time Variation of Fundamental Constants [PDF]
, 2008 We study the time variation of fundamental constants in the early Universe. Using data from primordial light nuclei abundances, CMB and the 2dFGRS power spectrum, we put constraints on the time variation of the fine structure constant $\alpha$, and the ...

Multipower variation for Brownian semistationary processes [PDF]
, 2011 In this paper we study the asymptotic behaviour of power and multipower variations of processes $Y$:\[Y_t=\int_{-\in fty}^tg(t-s)\sigma_sW(\mathrm{d}s)+Z_t,\] where $g:(0,\infty)\rightarrow\mathbb{R}$ is deterministic, $\sigma >0$ is a random process, $W$

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
