Byzantine Crosses with Inlay in the South-Western Crimea
Archaeological materials played an important role for the studies of the history of Christianity in the South-Western Crimea. Especially interesting are individual artefacts of Christian cult, pectoral crosses in particular.

Start with a necklace consisting of one white bead and one black bead, and add new beads one at a time by inserting each new bead between a randomly chosen adjacent pair of old beads, with the proviso that the new bead will be white if and only if both beads of the adjacent pair are black.

Primordial black holes from cosmic necklaces [PDF]
Cosmic necklaces are hybrid topological defects consisting of monopoles and strings. We argue that primordial black holes(PBHs) may have formed from loops of the necklaces, if there exist stable winding states, such as coils and cycloops.

Splitting Necklaces, with Constraints [PDF]
We prove several versions of Alon's "necklace-splitting theorem", subject to additional constraints. For illustration the "Equicardinal necklace-splitting theorem" claims that, without increasing the number of cuts, one can guarantee that each thief is ...

UNDERSCREENED KONDO NECKLACE [PDF]
It has been suggested recently by Gan, Coleman, and Andrei that studying the underscreened Kondo problem may help to understand the nature of magnetism in heavy fermion systems. Motivated by Doniach’s work on the S=1/2 Kondo necklace, we introduce the underscreened Kondo necklace models with S>1/2.

Cosmic Necklaces and Ultrahigh Energy Cosmic Rays [PDF]
Cosmic necklaces are hybrid topological defects consisting of monopoles and strings, with two strings attached to each monopole. We argue that the cosmological evolution of necklaces may significantly differ from that of cosmic strings.

Cosmic Necklaces from String Theory [PDF]
We present the properties of a cosmic superstring network in the scenario of flux compactification. An infinite family of strings, the (p,q)-strings, are allowed to exist.

We investigate the dynamics of rotating spin-orbit-coupled spin-1 Bose–Einstein condensates (BECs) in an in-plane gradient magnetic field, which is confined in an anharmonic trap.
