Inaccessible Singularities in Toral Cosmology [PDF]

, 2006
The familiar Bang/Crunch singularities of classical cosmology have recently been augmented by new varieties: rips, sudden singularities, and so on. These tend to be associated with final states. Here we consider an alternative possibility for the initial

Structures and Ribosomal Interaction of Ribosome-Inactivating Proteins

Molecules, 2016
Ribosome-inactivating proteins (RIPs) including ricin, Shiga toxin, and trichosanthin, are RNA N-glycosidases that depurinate a specific adenine residue (A-4324 in rat 28S ribosomal RNA, rRNA) in the conserved α-sarcin/ricin loop (α-SRL) of rRNA.

Sapovaccarin-S1 and -S2, Two Type I RIP Isoforms from the Seeds of Saponaria vaccaria L.

Toxins, 2022
Type I ribosome-inactivating proteins (RIPs) are plant toxins that inhibit protein synthesis by exerting rRNA N-glycosylase activity (EC 3.2.2.22). Due to the lack of a cell-binding domain, type I RIPs are not target cell-specific. However once linked to

The Vietoris-Rips complexes of a circle

, 2017
Given a metric space X and a distance threshold r>0, the Vietoris-Rips simplicial complex has as its simplices the finite subsets of X of diameter less than r.

Structure and Biological Properties of Ribosome-Inactivating Proteins and Lectins from Elder (Sambucus nigra L.) Leaves

Toxins, 2022
Ribosome-inactivating proteins (RIPs) are a group of proteins with rRNA N-glycosylase activity that catalyze the removal of a specific adenine located in the sarcin–ricin loop of the large ribosomal RNA, which leads to the irreversible inhibition of ...

Growth-Induced In-Plane Uniaxial Anisotropy in V$_{2}$O$_{3}$/Ni Films

, 2017
We report on a strain-induced and temperature dependent uniaxial anisotropy in V$_{2}$O$_{3}$/Ni hybrid thin films, manifested through the interfacial strain and sample microstructure, and its consequences on the angular dependent magnetization reversal.

La necesaria recuperación del diálogo social para abordar la regulación del impacto de las nuevas tecnologías en los derechos de los trabajadores [PDF]

, 2019
The European Union has urged the European Commission, Member States and social partners to establish rules for an economic sphere which is either deregulated or has significant gaps in regulation: digitilisation and the platform economy.

Sibling gender dynamics and childhood stunting in Ghana

BMC Nutrition
Background Stunting remains a public health concern in sub-Saharan Africa. Despite the evolving awareness of the effect of family composition on child health outcomes, the influence of sibling gender on stunting has seldom been consistent.
