Mandarin Resultative Verb Compounds, different from any simplex words, have complicated θ-structures, since both the verb (Vcaus) and its complement (Cres) have the capacity of assigning their own thematic roles. The thematic roles assigned by Vcaus form the θ-structure's main structure, and those assigned by Cres form the embedded structure. Sometimes an entity plays a role in the main structure, and at the same time plays a role in the embedded structure. If the two roles are identical, they are "coindexed"; if they are different, they form a composite role. RVC's θ-structure is further compounded when ambiguity occurs and when causation is taken into consideration. The ambiguity of RVCs can be attributed to the different combination of thematic roles. As for causation, the two causative roles, causer and cause, can be assigned to thematic roles according to certain constraints.

Abstract On the basis of the argument realization of Mandarin resultative verb compounds, this paper argues that the Proto-Agent properties as well as the Proto-Patient properties proposed by Dowty (1991) are not equal in status. Specifically, the Proto-Agent property corresponding to the Causer and the Proto-Patient property corresponding to the Causee are two higher-ranked properties. In a non-prototype approach to thematic roles, this means that the Causer and the Causee are two higher-ranked thematic roles that are immediately relevant to the argument realization of monotransitive causative predicates. The paper shows that, compared with Dowty’s equal-weight approach, the alternative approach recognizing the Causer and the Causee as two higher-ranked properties or roles can give a simpler, more effective, and more straightforward account of the argument realization associated with monotransitive causative predicates, including lexical causatives, morphological causatives, and resultatives. This study has implications for research in the argument realization of causatives involving three (or more) arguments as well. Meanwhile, it has implications for any theory utilizing thematic hierarchy because (i) none of the thematic hierarchies proposed in the literature includes both the Causer and the Causee and (ii) a complete theory of thematic roles needs to take these two higher-ranked roles into consideration.

Role Assignment

This paper examines the role of elements of English sentences by employing the approach ofthematic role assignment. The emphasis is on how the positioning of words and phrases insyntactic structure helps determine the roles that the referents of NPs play in the situationdescribed by the sentences. The results reveal that the position of an NP’s determines itsthematic role and. There is a relevance between deep syntactic structure and the assignmentof thematic roles for every NP in the sentence.

Controlled Systems

A closed-loop controlled system usually consists of the main structure, sensors, and actuators. The dynamics of sensors and actuators may influence the motion of the main structure. This article presents an analytical study on the first-passage reliability of a nonlinear stochastic controlled system under the consideration of the dynamics of sensors and actuators. The coupled dynamic equations of the controlled systems with sensors and actuators are first given, which are further integrated into a controlled, randomly excited, dissipated Hamiltonian system. By applying the stochastic averaging method for quasi-Hamiltonian systems, a one-dimensional averaged differential equation for the Hamiltonian function is obtained. The backward Kolmogorov equation associated with the averaged equation is then derived for the first-passage reliability analysis, from which the approximate reliability function and probability density of first-passage time are obtained. The accuracy of the proposed procedure is demonstrated by an example. A comparative analysis of the reliability of the system with/without sensors and actuators is carried out, which indicates that ignoring sensors and actuators will make underestimation of the reliability of the closed-loop system with small time. However, when time increases, there appears the opposite trend. Our findings provide a reference for control strategy design.

Main Structure

Three-dimensional composite preform is the main structure of fiber-reinforced composites. During the weaving process of large-sized three-dimensional composite preform, relative rotation or translation between the fiber feeder and guided array occurs before feeding. Besides, the weaving needles can be at different heights after moving out from the guided array. These problems are mostly detected and adjusted manually. To make the weaving process more precise and efficient, we propose machine vision-based methods which could realize accurate estimation and adjustment of the relative position-pose between the fiber feeder and guided array, and make the needles pressing process automatic by recognizing the position of the weaving needles. The results show that the estimation error of relative position-pose is within 5%, and the rate of unrecognized weaving needles is 2%. Our proposed methods improve the automation level of weaving, and are conducive to the development of preform forming toward digital manufacturing.

The title compound, lithium/sodium iron(III) bis[orthomolybdate(VI)], was obtained by a solid-state reaction. The main structure units are an FeO6octahedron, a distorted MoO6octahedron and an MoO4tetrahedron sharing corners. The crystal structure is composed of infinite double MoFeO11chains along theb-axis direction linked by corner-sharing to MoO4tetrahedra so as to form Fe2Mo3O19ribbons. The cohesion between ribbonsviamixed Mo—O—Fe bridges leads to layers arranged parallel to thebcplane. Adjacent layers are linked by corners shared between MoO4tetrahedra of one layer and FeO6octahedra of the other layer. The Na+and Li+ions partially occupy the same general position, with a site-occupancy ratio of 0.631 (9):0.369 (1). A comparison is made withAFe(MoO4)2(A= Li, Na, K and Cs) structures.
