Chromosomal inversion clines paralleling the long-standing ones in native Palearctic populations of Drosophila subobscura evolved swiftly after this species invaded the Americas in the late 1970s and early 1980s. However, the new clines did not consistently continue to converge on the Old World baseline. Our recent survey of Chilean populations of D. subobscura shows that inversion clines have ...

We solve two related extremal problems in the theory of permutations. A set Q of permutations of the integers 1 to n is inversion-complete (resp., pair-complete) if for every inversion (j, i), where 1 ≤ i < j ≤ n, (resp., for every pair (i, j), where i 6= j) there exists a permutation in Q where j is before i. It is minimally inversion-complete if in addition no proper subset of Q is inversion-...

Upside-down inversion disrupts the processing of spatial relations between the features of a face, while largely preserving local feature analysis. However, recent studies on face inversion failed to observe a clear dissociation between relational and featural processing. To resolve these discrepancies and clarify how inversion affects face perception, the authors monitored inversion effects se...

It has been repeatedly shown that face inversion affects the recognition of emotional faces. However, previous results are heterogeneous concerning the affected emotions and the influence of presentation time is unclear. We examined the impact of limited presentation time (200 ms) on the face-inversion effect during recognition of basic emotions in 128 healthy young adults. Data analysis reveal...

In recent years, neural network based acoustic-to-articulatory inversion approaches have achieved the state-of-the-art performance. One major issue associated with these approaches is the lack of phone sequence information during inversion. In order to address this issue, this paper proposes an improved architecture hierarchically concatenating phone classification and articulatory inversion co...

Minimum-structure inversion has been widely used in both hydrocarbon and mineral exploration for decades. However, models obtained with this method typically exhibit smooth variation of physical properties and smeared-out boundaries, and may not give detailed information about the target being investigated. In this paper we present a constrained joint inversion of surface and borehole gravity t...

We give a survey of the Lagrange inversion formula, including different versions and proofs, with applications to combinatorial and formal power series identities.
