Abstract We propose to generate and control stationary one-way steering with strong entanglement between photon magnon modes by the cooperative effect of coherent coupling dissipative coupling. Due combination two couplings, system becomes a parity-time-like symmetric non-Hermitian system, exceptional points (EPs)-like appear in real imaginary parts eigenvalues. demonstrate that especially obvi...

In [1] it was shown that there are very effective attacks leading to collisions for the hash function MD4 designed by R. Rivest [3]. A summary of the status of hash functions of the MD4-family with respect to collision-resistence can be found in [2] and [4]. However, attacking the one-wayness of a hash function is a much more demanding challenge, and in case of success it has much more devastat...

this note introduces a new general conjecture correlating the dimensionality dt of an infinitelattice with n nodes to the asymptotic value of its wiener index w(n). in the limit of large nthe general asymptotic behavior w(n)≈ns is proposed, where the exponent s and dt are relatedby the conjectured formula s=2+1/dt allowing a new definition of dimensionality dw=(s-2)-1.being related to the topol...
