Die Partikeln schon und noch in der linearen Abfolge mit Temporaladverbien

The particles schon and noch in German add an aspectual reading to events in different assertions. While schon tends to a perfective reading of an event, an imperfective reading appears with noch, hence both particles have a similar function on the event modification. Overtly, they are located unrestricted in the middle field of a German clause and can freely change their position towards temporal adverbs such as heute, jetzt, bald etc. It seems that syntax does not have an impact to order schon heute or heute schon. This variation is of main interest of the paper: Is there a linear restriction of adverbs and schon/noch, and does a change in the output cause a reinterpretation? The paper presents main assumptions on the word order of aspectual particles and temporal adverbs from the semantic and the syntactic perspective. An experimental study on prosodic factors will complete the overview and its preferences for the linearization of the sequences in question. The result is that common categorical grammar is not able to account for all possible outcomes with respect to contextual preferences. Therefore, a more flexible grammar concept is needed to build a usage-based concept on word order variation for these functional elements.

Developing pro-drop

The syntax of Cimbrian, a Germanic heritage language, is at a peculiar developmental stage: on the one hand it has lost the V2 linear restriction, but still maintains both pronominal subject inversion and a residual root-embedded word order asymmetry; on the other, it is characterized by both ‘free’ subject inversion (VP DP) and the systematic violation of the ‘that-trace’ filter, but does not allow null subjects (NSs). This specific mixture of both V2- and pro-drop properties gives us an opportunity to revisit the traditional assumption that Germanic V2 is incompatible with full pro-drop. In this work, we propose that the development of pro-drop crucially depends on the loss of V-to-Fin movement and, consequently, on the lowering of structural subject agreement within TP so that the whole complex process of feature sharing (KEEP, SHARE, DONATE) between C and I is restructured, changing from a C-dominant system to an I-dominant system.

Linear Association in Compositional Data Analysis

With compositional data ordinary covariation indexes, designed for real random variables, fail to describe dependence. There is a need for compositional alternatives to covariance and correlation. Based on the Euclidean structure of the simplex, called Aitchison geometry, compositional association is identied to a linear restriction of the sample space when a log-contrast is constant. In order to simplify interpretation, a sparse and simple version of compositional association is dened in terms of balances which are constant across the sample. It is called b-association. This kind of association of compositional variables is extended to association between groups of compositional variables. In practice, exact b-association seldom occurs, and measures of degree of b-association are reviewed based on those previously proposed. Also, some techniques for testing b-association are studied. These techniques are applied to available oral microbiome data to illustrate both their advantages and diculties. Both testing and measurements of b-association appear to be quite sensible to heterogeneities in the studied populations and to outliers.

How to define relaxed V2 languages and how to distinguish them from non-V2 languages: A reply to Brandtler (2014)

This paper provides evidence for the idea that relaxed verb-second (V2) languages exist and exhibt specific properties which distinguish them from both strict V2 and non-V2 languages. The identification of the relaxed subtype of V2 languages implies that V2 should not be understood as a linear restriction, but as an abstract rule involving the movement of the finite verb to a head of the left periphery in all main clauses.

A Method of Multi-View Images 3D Restructuring of Discrete Line Segments

In this paper, the average reprojection geometrical errors on all images of a spatial straight line is taken as the restructuring and optimization target function to ensure the optimal result to be acquired; a spatial straight line is expressed by use of the Plücker coordinates for the proposal of the analytical method of correcting the double linear restriction on the Plücker coordinates of noise-included spatial straight lines; during the optimization process, to ensure parameters that meet double linear restriction, the iteration renewal process is expressed by at least 4 parameters, to increase the precision of restructuring results. Experiments results derived from simulation data and real images have all demonstrated the high efficiency and precision of the algorithm proposed in this paper.
