Journal of High Energy Physics, 2017 We analyze neutrinoless double beta decay (0νββ) within the framework of the Standard Model Effective Field Theory. Apart from the dimension-five Weinberg operator, the first contributions appear at dimension seven.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Investigating the role of islet cytoarchitecture in its oscillation using a new beta-cell cluster model. [PDF]
PLoS ONE, 2007 The oscillatory insulin release is fundamental to normal glycemic control. The basis of the oscillation is the intercellular coupling and bursting synchronization of beta cells in each islet.

Synthesis of RNA Nucleotides under Probably Prebiotic Conditions [PDF]
, 2022 RNA being composed of multiple covalently linked nucleotides is thought to have been a precursor to life circa 4.3-3.8 billion years ago. Non-enzymatically formed adenosine monophosphate (AMP), more specifically, is a vitally important subtopic of the ...

Reduced number of endothelial progenitor cells in adult patients with beta thalassemia major
Annals of HematologyBeta-thalassemia major (TM) is associated with a high incidence of thromboembolic events and prothrombotic changes, suggesting a chronic hypercoagulable state.

Estimating discrete curvatures in terms of beta numbers
, 2016 For an arbitrary Radon measure $μ$ we estimate the integrated discrete curvature of $μ$ in terms of its centred variant of Jones' beta numbers. We farther relate integrals of centred and non-centred beta numbers. As a corollary, employing the recent result of Tolsa [Calc. Var.

Local set approximation: Mattila-Vuorinen type sets, Reifenberg type sets, and tangent sets [PDF]
, 2014 We investigate the interplay between the local and asymptotic geometry of a set $A \subseteq \mathbb{R}^n$ and the geometry of model sets $\mathcal{S} \subset \mathcal{P}(\mathbb{R}^n)$, which approximate $A$ locally uniformly on small scales.

The beta-transformation's companion map for Pisot or Salem numbers and their periodic orbits [PDF]
, 2017 The -transformation of the unit interval is de ned by T (x) := x (mod 1). Its eventually periodic points are a subset of [0; 1] intersected with the eld extension Q( ). If > 1 is an algebraic integer of degree d > 1, then Q( ) is a Q-vector space
