Dual VP Classes
No full textWe consider the complexity class ACC1 and related families of arithmetic circuits. We prove a variety of collapse results, showing several settings in which no loss of computational power results if fan-in of gates is severely restricted, as well as presenting a natural class of arithmetic circuits in which no expressive power is lost by severely restricting the algebraic degree of the circuits. We draw attention to the strong connections that exist between ACC1 and VP, via connections to the classes CC1[m] for various m. These results tend to support a conjecture regarding the computational power of the complexity class VP over finite algebras, and they also highlight the significance of a class of arithmetic circuits that is in some sense dual to VP. In particular, these dual-VP classes provide new characterizations of ACC1 and TC1 in terms of circuits of semiunbounded fan-in. As a corollary, we show that ACCi = CCi for all i 1.The earlier conference paper version of this article is available from the publisher at http://link.springer.com/book/10.1007%2F978-3-662-48054-0 and also from the Rutgers institutional repository: http://dx.doi.org/doi:10.7282/T3KK9DN4.Peer reviewe
Exploring VP/vP Preposing in Multiple Nominative Constructions mm
No full textThis study investigates VP/vP preposing within the context of Multiple
Nominative Constructions (MNCs). In Korean, a verbal constituent can be
moved to the sentence-initial position. However, when an unbound trace is
contained within the preposed constituent, it violates the Proper Binding
Condition (PBC), rendering the sentence ungrammatical. The PBC effect has
non-trivial implications for the structure of VP/vP. This paper investigates
VP/vP preposing across diverse categories of MNCs in Korean to illuminate
their structural characteristics. MNCs occur in various environments, broadly
classified into Major Subject constructions and Nominative Object constructions
(Kuno 1973). Previous literature classifies the two types of MNCs into several
sub-types. An important question is concerned with the structure of the various
MNCs. This paper explores whether previous analyses can adequately explain
the (im)possibility of VP/vP preposing within each sub-type of MNCs. We
show that the (im)possibility of VP/vP preposing in MNCs results from their
unique structure, in combination with the PBC effect and many other syntactic
principles.We thank the anonymous reviewers of this journal for many useful comments. This work was supported by the 2021 Yeungnam University Research Grant (Corresponding Author)
An Optimality-Theoretic Analysis of Scandinavian Object Shift and Remnant VP-Topicalisation
No full textHolmberg (1997, 1999) assumes that Holmberg's generalisation (HG) is derivational, prohibiting Object Shift (OS) across an intervening non-adverbial element at any point in the derivation. Counterexamples to this hypothesis are given in Fox & Pesetsky (2005) which show that remnant VP-topicalisations are possible in Scandinavian as long as the VP-internal order relations are maintained. Extending the empirical basis concerning remnant VP-topicalisations, we argue that HG and the restrictions on object stranding result from the same, more general condition on order preservation. Considering this condition to be violable and to interact with various constraints on movement in an Optimality-theoretic fashion, we suggest an account for various asymmetries in the interaction between remnant VP-topicalisations and both OS and other movement operations (especially subject raising) as to their order preserving characteristics and stranding abilities.The definitive version of this paper is published in Linguistics in Potsdam 25 (2006).Engels, E., Vikner, S.

Molecular recognition of Ca2+ cations by internal and external receptors/interfaces in a spherical porous molybdenum-oxide capsule: unusual coordination scenarios. Inorganic Chemistry Frontiers. 2014;1(10):740-744.The unique molybdenum-oxide capsule [{(Mo-VI)(Mo5O21)-O-VI(H2O)(6)}(12){(Mo2O4)-O-V(SO4)}(30)](72-) shows an unprecedented affinity towards Ca2+ cations which interact in fully or partially hydrated forms with different well-defined internal and external receptor areas via direct coordination and/or hydrogen bonds. The cavity of the capsule comprises an unusual "water assembly" of the Ca-20{H2O}(60)equivalent to Ca-20{(H2O)(5)}(12) type. Altogether, we can refer to a unique solid-state structure

Deriving Pairedness in vP structure: Minimalist yet Optimal
No full textMinimalist accounts lack a natural theory of markedness, whereas Optimality-Theoretical accounts lack derivational procedure. We argue, then, that neither standard Minimalist nor standard Optimality-Theoretical frameworks enable straightforward, parsimonious accounts of what we call pairedness behavior, where a given language exhibits multiple forms occupying the same niche. We adopt a hybrid OT/MP account, first, to explain the unmarked/marked dichotomy of anticausatives in German, and, second, to explain why languages often exhibit direct and indirect causatives.This is the authors' final version of a book chapter that was published in Optimality Theory and Minimalism: Interface Theories.Grove, Kyle Wade and Putnam, Mike.
