zerofold

Although paramagnetic, this species is unlikely to be detected by epr because of (1) zerofold splitting of the S = 2 ground state, which shifts allowed transitions to inaccessible magnetic fields and (2) unusually short spin-lattice relaxation times.

With decreasing total efficiency there is an apparent decrease of the impact parameter range caused by the strong increase of the unobserved zerofold probability in correspondence of low-multiplicity peripheral events.

Quantitation of these results by densitometry revealed that JAK3 was demonstrably up-regulated following SAC and antiCD40 stimulation (fourfold increase relative to actin) while JAK1 and STAT3 levels remained constant (zerofold increase relative to actin).

Likewise, we assume that zerofold convolutions of the distributions a, b, and y are Dirac distributed with a constant value of zero.

The existence ratio of m/z 212.01 in the postdosed human urine samples at day 9 were approximately zerofold higher when compared to the predosed human urine samples,[…]The existence ratio of m/z 664.3126 in the alcohol treated rats was approximately fivefold higher, when compared to that in the control group rats, and YCHT treated group at day 9, and the existence ratio of m/z 708.2932 in the alcohol treated rats was approximately zerofold higher when compared to that in the control, and YCHT treated group rats at day 9.
