In [K. R. Fuller, on indecomposable injectives over artinian rings, Pacific J. Math. 29 (1969), 115-135, Theorem 3.1] K. R. Fuller gave necessary and sufficient conditions for projective left modules to be injective over a left artinian ring. In [Y. Baba and K. Oshiro, On a theorem of Fuller, prepri

In this paper, we study the existence of ⊥ -envelopes, -envelopes, ⊥ -envelopes, -covers, and -covers where and denote the classes of modules of injective and projective dimension less than or equal to a natural number n, respectively. We prove that over any ring R, special ⊥ -preenvelopes and speci
This article details the performance of a Ka-band oscillator under the influence of an external injection-locking signal used for direct phase shifi keying of a microwave signal. The results obtained indicate that it is possible to obtain at least 100" of phase change for a PHEMT MMIC oscillator ope
