Quantum systems which are discrete both in space and time can be realized with pseudo-spin-1⁄2 atoms stored in the spin-dependent optical lattice presented inlecture I: the quantum state evolves in a digital way through finite time steps, with spatial …

We have discovered a process, Silica Cell Replication , wherein mammalian cells direct their exact replication in silica . The silica cell replicas preserve nm-to macro-scale cellular features and dimensions on both the cell surface and interior after …

Both simple atoms and photons can be described by two quantum states only, e.g. two selected internal states for atoms, two polarization states for photons. In a new language, introduced over the past two decades, such objects are now considered carriers …

Riet van Bremen's last lesson dealt with the representation of Hellenistic neos in the plastic arts and through certain portraits or anecdotes handed down through literary tradition, since it is only through these that we can form an idea of their …

Stable nanoparticles capable of specifically binding to cancer cells and delivering high doses of therapeutic compounds could be transformational for cancer therapy by making drug delivery into cancer cells more efficient, while reducing toxic side …

Atoms and photons are the principal cases of microscopic particles, the hallmarks of quantum objects. For more than a century they have served as conceptual models to understand and investigate the microscopic structure of matter. More than 30 years ago …

In Book IV (53-55) of his Histories , Polybius describes the civil war that tore the city of Gortyne apart from 221 to 219 BC, a conflict in which the neoi (or neoteroi ) violently opposed the presbyteroi . This rupture, apparently presented as …

Self-Assembly Living systems provide us many examples of intricately organized composite architectures preserved in silica or calcium carbonate. Most natural composites are formed by complex biomineralization processes; however, recently, self-assembly …

In Cyzique, on the shores of the Propontide (Sea of Marmara), among the considerable gifts made to the people of this city by Philetairos, first dynast of Pergamon (OGIS 748 ) , we find mention of a sum of 26 talents of silver offered "for the oil and …
