Recent stimulation studies in monkeys and humans have shown strong interactions between ventral premotor cortex (area F5) and the hand area of primary motor cortex (M1). These short-latency interactions usually involve facilitation from F5 of M1 outputs to hand muscles, although suppression has also been reported. This study, performed in three awake macaque monkeys, sought evidence that these ...

Picking up an object requires two basic motor operations: reaching and grasping. Neurophysiological studies in monkeys have suggested that the visuomotor transformations necessary for these two operations are carried out by separate parietofrontal circuits and that, for grasping, a key role is played by a specific sector of the ventral premotor cortex: area F5. The aim of the present study was ...

Two nearly degenerate positive-parity bands with the ?g9/22??g9/2?1 configuration and three negative-parity ?g9/2(p3/2,f5/2)??g9/2?1 have been identified in 81Kr. They are interpreted as chiral doublet pseudospin-chiral triplet bands, which is supported by constrained covariant density functional theory multiparticle plus rotor model calculations. The present work reports two new configurations...

Signature-based algorithms are a popular kind of algorithms for computing Gröbner basis, including the famous F5 algorithm, F5C, extended F5, GV and the GVW algorithm. In this paper, an efficient method is proposed to solve the detachability problem. The new method only uses the outputs of signature-based algorithms, and no extra Gröbner basis computations are needed. When a Gröbner basis is ob...

This study describes the isolation and subsequent characterization of four mammalian cell lines resistant to ethidium bromide (EB). Treatment of the simian virus 40- (SV40) transformed hamster cell line F5-1 first led to the establishment of the F2 cell line, which is resistant to 2 microg EB/ml. At this concentration cytochromes c and b are present in almost normal or only slightly diminished ...
