We motivate and present a proposal for how to represent extended finite state machine behavioural models with rich hierarchical states and compositional control structures (e.g., the Statecharts family) in SMT-LIB. Our goal with such a representation is to facilitate automated deductive reasoning on such models, which can exploit the structure found in the control structures. We present a novel...

Statistical MT has made great progress in the last few years, but current translation models are weak on re-ordering and target language fluency. Syntactic approaches seek to remedy these problems. In this paper, we take the framework for acquiring multi-level syntactic translation rules of (Galley et al., 2004) from aligned tree-string pairs, and present two main extensions of their approach: ...

We present a morphology-aware nonparametric Bayesian model of language whose prior distribution uses manually constructed finitestate transducers to capture the word formation processes of particular languages. This relaxes the word independence assumption and enables sharing of statistical strength across, for example, stems or inflectional paradigms in different contexts. Our model can be use...

This paper presents optimizations for verifying systems with complex time-invariant constraints. These constraints arise naturally from modeling physical systems, e.g., in establishing the relationship between different components in a system. To verify constraint-rich systems, we propose two new optimizations. The first optimization is a simple, yet powerful, extension of the conjunctivepartit...

conclusions it seems that applying prp is an effective therapeutic approach for wound healing, and faster wound healing is expected due to the presence of more platelets and growth factors. results at the end of study, the prp group showed a greater reduction in the edema ecchymosed discharge approximation (reeda) score compared to the control group (85.5% reduction in the prp group; 72% in the...

background platelet rich plasma is known for its hemostatic, adhesive and healing properties in view of the multiple growth factors released from the platelets to the site of wound. the primary objective of this study was to use autologous platelet rich plasma (prp) in wound beds for anchorage of skin grafts instead of conventional methods like sutures, staplers or glue. methods in a single cen...

autologous fat transfer offers many qualities of a ideal soft tissue filler. main advantages of fat grafting ensue from the fact that the lipoaspirate tissue is an abundant source of regenerative pluripotential cells. however, the reported rates of fat cell survival vary greatly in the medical literature (10-90%). different techniques of harvesting, processing, and reinjecting the fat cells are...

background cartilage tissue has limited regenerative capacity and the management of cartilage defects has always been a challenging issue. platelet-rich plasma (prp) has been recently been used to improve healing of cartilage defects. in the present experiment, we aimed to investigate the effects of prp on regeneration capacity as well as survival of the cartilage grafts in a rabbit model. meth...

overuse of chemical inputs and inappropriate use of water resources have caused unsustainability in most agricultural regions of marvdasht county in fars province. for an attainment of sustainable production of wheat, it is necessary to design appropriate communicational models for agricultural inputs and for water optimum usage, however, reviewing agricultural development literature revealed t...
