    "abstract": "The partial scaling transform of the density matrix for multiqubit states is\nintroduced to detect entanglement of quantum states. The transform contains\npartial transposition as a special case. The scaling transform corresponds to\npartial time scaling of subsystem (or partial Planck\u0027s constant scaling) which\nwas used to formulate recently separability criterion for continous variables.A\nmeasure of entanglement which is a generalization of negativity measure is\nintroduced being based on tomographic probability description of spin states.",
