Prosody as an argument for a layered left periphery

Van Heuven and Haan’s (2000, 2002) experimental work on the prosody of Dutch question types found that the prosodic signalling of interrogativity is stronger for declarative questions, less so for yes/no-questions and even less so for wh-questions. This paper shows how the sequence established on prosodic grounds (declarative questions > yes/no questions > wh questions > statements) is mirrored in the functional hierarchy in syntax. Prosody therefore provides an argument for a detailed left periphery (Rizzi 1997, 2001; Haegeman & Hill 2013)

Substituent effects on absorption spectra of pH indicators: an experimental and computational study of sulfonphthaleine dyes

Sulfonphthaleine dyes are an important class of pH indicators, finding applications in novel (textile) sensors. In this paper, we present a combined experimental and theoretical study to elucidate the halochromic behaviour of a large set of sulfonphthaleine compounds. Starting from an experimental analysis consisting of UV-Vis spectroscopy, the pH region and the absorption wavelengths related to the colour shift are obtained and pK(a) values are derived. The effect of the substituents on the pH region can be traced back to their electron donating/withdrawing properties. Time-Dependent Density Functional Theory (TD-DFT) is able to adequately produce the trend in experimental wavelengths. Proton affinities are used to assess the effect of substituents on the pH region. The combination of theory and experiment is able to give a better understanding of the pH sensitivity; the methodology in this work will be useful in future dye design and is applicable to other dye classes as well.

80 years of electrospinning

Electrospinning is a relatively simple fibre-forming process and offers a unique method to produce nanofibers. The process exists at this moment 80 years and has seen a very turbulent history. There is a need to see what actually happened in this history. We have taken a brief look in the history of electrospinning. This paper is reporting on some of the aspects that electrospinning encountered. It is crucial to see that electrospinning has been used in different countries in different time periods. The history of electrospinning is mainly characterised by bad timing. The future of electrospinning looks however quit bright

ABA revisited : evidence from Latin and Czech degree morphology

We present a novel account of root suppletion in comparatives and superlatives, and show how it accounts for the presence of ABB and ABC patterns, as well as the absence of ABA patterns. The account assumes that suppletive roots, despite appearances to the contrary, are not contextual allomorphs, but portmanteaus spelling out two distinct features, one belonging to the lexical root, and another one belonging to the comparative. The regular comparative affix then spells out an additional feature relating to the comparative domain. In other words, we show that the comparative (CMPR) head that enters into the morphological makeup of the comparative (Bobaljik 2012) is to be split up into two distinct heads, C1 and C2 (see also Caha 2016). We extend this idea to SPRL, which we show is likewise to be split up into S1 and S2, in order to account for suppletive ABC patterns. These four distinct heads receive empirical support from facts of the degree morphology in Czech and Latin. The new account of root suppletion allows a straightforward way of deriving the attested and unattested patterns of (root) suppletion in degree comparison. The analysis developed supports the hypothesis that the absence of AAB patterns in degree comparison is due to a constraint of a different nature altogether

Splitting up the comparative : evidence from Czech

We argue that the comparative head that enters into the mor- phologicalmakeupofthecomparative (Bobaljik 2012) is to be split up into two distinct heads(see Caha 2016). Evidence for this claim comes from Czech comparative morphology, root suppletion, and the inter- action of Czech suppletion with negation. We further argue that the account for root suppletion that we provide captures the data better than a Distributed Morphology (DM) account

Unmerging analytic comparatives

We look at the internal structure of the English analytic comparative marker more, arguing that it spells out nearly all the features of a gradable adjective. When this marker is merged with an adjective in the positive degree, it creates a situation of feature recursion or overlap, where more duplicates certain features that are also present in the adjective that it modifies. We argue that such overlap must be disallowed as a matter of principle. We present an empirical argument in favour of such a restriction, which is based on the generalization that comparative markers which occur to the left of the adjectival root are incompatible with suppletion. This generalization can be shown to follow from a restriction against overlapping derivations. In order to achieve such nonoverlapping derivations, an Unmerge operation may remove previously created structure
