Quantum scaling laws in the onset of dynamical delocalization [PDF]

open access: yes, 2006
We study the destruction of dynamical localization, experimentally observed in an atomic realization of the kicked rotor, by a deterministic Hamiltonian perturbation, with a temporal periodicity incommensurate with the principal driving. We show that the

Chondrule destruction in nebular shocks

open access: yes, 2014
Chondrules are millimeter-sized silicate spherules ubiquitous in primitive meteorites, but whose origin remains mysterious. One of the main proposed mechanisms for producing them is melting of solids in shock waves in the gaseous protoplanetary disk ...

Respectful Destruction

open access: yesVoices in Bioethics, 2014
Cryogenically frozen embryos present a major problem for virtually all fertility centers across the globe. As procedures for IVF, including egg retrieval and Inter-cytoplasmic-sperm-insemination (ICSI), have become more precise, predictable, and promising, the production of excess viable embryos now leaves couples with the decision to freeze or discard

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
