Two representations of case: Evidence from numerals and relatives

This squib highlights a fundamental tension between the representations required for case syncretism versus the representations required for case priority. Case syncretism is captured with a feature decomposition based on the patterns established in Caha 2009. However, a different decomposition is required for case priority relations, which are instantiated in Bosnian/Croatian/Serbian (BCS) numeral constructions and in BCS and German relative constructions. The squib proposes that this conflict can be resolved by introducing two levels of representation into the case system, where priority is determined by set structures in the syntax, while syncretism is analyzed following post-syntactic set unification.

Accusative case assignment to the verbal internal argument in the Albanian language and the corresponding case assigning model

The following paper aims at shedding some light on Albanian language case system with special focus on the assignment of accusative case. As a member of the vast Indo-European family Albanian language is characterized by an inflected case system and as so a free word order. Traditionally, we are taught and we still teach to the coming generations that accusative case is assigned mostly by the verb to that sentence noun phrase syntactically representing the direct object and semantically introducing the Theme or the Patient. Moreover in Albanian accusative is also assigned by another morphological category bearing the distinctive features [+noun;+verb], namely the preposition. Furthermore, as a researcher in the field of generative syntax I have a stake at analyzing certain exceptional cases of accusative case assignment to the subject NP of the Albanian subjunctive clause. In conclusion, I was really tempted to adopt Chomsky’s reconciling proposal in accusative case assignment under the specifier-head structural and schematic relation.

From case to topology

The Scanian dialect of Middle Danish underwent a range of changes and reductions in its case system. I argue that these changes were caused neither by phonological developments nor by language contact as often assumed, but by multiple processes of grammaticalisation. The present paper focuses on one of these factors: that the relatively predictable constituent order within the Middle Danish noun phrase made case marking redundant in its function of marking noun-phrase internal agreement between head and modifier(s). This redundancy caused the case system to undergo a regrammation where the indexical sign relations changed so that the expression of morphological case no longer indicated this noun-phrase-internal agreement, leaving only topology (as well as morphologically marked number and gender agreement) as markers of this type of agreement. This factor contributed to the subsequent degrammation of the entire case system.

ACD/Structure Elucidator: 20 Years in the History of Development

The first methods associated with the Computer-Assisted Structure Elucidation (CASE) of small molecules were published over fifty years ago when spectroscopy and computer science were both in their infancy. The incredible leaps in both areas of technology could not have been envisaged at that time, but both have enabled CASE expert systems to achieve performance levels that in their present state can outperform many scientists in terms of speed to solution. The computer-assisted analysis of enormous matrices of data exemplified 1D and 2D high-resolution NMR spectroscopy datasets can easily solve what just a few years ago would have been deemed to be complex structures. While not a panacea, the application of such tools can provide support to even the most skilled spectroscopist. By this point the structures of a great number of molecular skeletons, including hundreds of complex natural products, have been elucidated using such programs. At this juncture, the expert system ACD/Structure Elucidator is likely the most advanced CASE system available and, being a commercial software product, is installed and used in many organizations. This article will provide an overview of the research and development required to pursue the lofty goals set almost two decades ago to facilitate highly automated approaches to solving complex structures from analytical spectroscopy data, using NMR as the primary data-type.

Low postoperative blood platelet count may be a risk factor for 3-year mortality in patients with acute type A aortic dissection

Background Mortality and complications remain high after acute type A aortic dissection (ATAAD) open surgery and are associated with coagulation dysfunction. Platelets play an important role in the process of coagulation. This study explored the relationship between postoperative platelet counts and 3-year mortality after operation in patients with ATAAD undergoing open aortic repair surgery. Methods Patients with ATAAD who underwent Total Arch Replacement and Frozen Elephant Trunk in Fuwai Hospital from 2011 to 2015 were selected for this study. The perioperative data were collected and sorted through the electronic clinical case system. Multivariate Logistic regression was used to analyze the risk factors for death within three years after surgery. Results A total of 495 patients were included in the analysis. After correction for confounding factors, decreased postoperative platelet count remained an independent factor that was associated with lower mortality (OR = 0.918, 95% CI 0.853–0.988, P = 0.023). Conclusions The study indicated that decreased postoperative platelet count may lead to increased 3-year mortality, in patients with ATAAD who underwent open aortic repair surgery.

Model-Driven Architectural Framework towards Safe and Secure Nuclear Power Reactors

Sensor-based digital systems for Instrumentation and Control (I&C) of nuclear reactors are quite complex in terms of architecture and functionalities. A high-level framework is highly required to pre-evaluate the system’s performance, check the consistency between different levels of abstraction and address the concerns of various stakeholders. In this work, we integrate the development process of I&C systems and the involvement of stakeholders within a model-driven methodology. The proposed approach introduces a new architectural framework that defines various concepts, allowing system implementations and encompassing different development phases, all actors, and system concerns. In addition, we define a new I&C Modeling Language (ICML) and a set of methodological rules needed to build different architectural framework views. To illustrate this methodology, we extend the specific use of an open-source system engineering tool, named Eclipse Papyrus, to carry out many automation and verification steps at different levels of abstraction. The architectural framework modeling capabilities will be validated using a realistic use case system for the protection of nuclear reactors. The proposed framework is able to reduce the overall system development cost by improving links between different specification tasks and providing a high abstraction level of system components.

Russian Polyptoton: Grammatic Form and Rhetorical Content

The article uses a narrow understanding of polyptoton (repetition of a word in different cases), which goes back to classical rhetoric. This allows to consider the specifics of the polyploton in the Russian language with its developed case system. The Russian polyptoton can be reduced to four types. We distinguish an intensive polyptoton, an extensive polyptoton, a contrasting polyptote and a descriptive set type. All these types express the category of plurality in different ways. A good example of intensive polyploton is biblical phrases like “song of songs”. Such a polyptot is called a genitive superlative. There is also a way of expressing superlativeness in Russian with the help of the instrumental case like дурак дураком. Intensive polyptoton can also express the meaning of reflexivity: слово о словах, каталог каталогов. The extensive type of polyptote coincides with a figure called an epimone. Unlike the other three types of polypoton, it is not associated with binomials and can form a rather long row with a word in different cases. The contrasting polyptoton is the antithesis within one word, as in the Latin proverb: homo homini lupus est. Polyptoton describing a set - a phenomenon not yet studied in Russian grammar. The Russian polyptoton is interesting in that it manifests itself in different inflections. Therefore, the widespread understanding of a polypoton as a repetition of words with one root is not relevant for the Russian language. Russian polyptoton is as far as possible from paranomazia, pun. Its grammatical nature is strongly expressed.

Active Inferants: An Active Inference Framework for Ant Colony Behavior

In this paper, we introduce an active inference model of ant colony foraging behavior, and implement the model in a series of in silico experiments. Active inference is a multiscale approach to behavioral modeling that is being applied across settings in theoretical biology and ethology. The ant colony is a classic case system in the function of distributed systems in terms of stigmergic decision-making and information sharing. Here we specify and simulate a Markov decision process (MDP) model for ant colony foraging. We investigate a well-known paradigm from laboratory ant colony behavioral experiments, the alternating T-maze paradigm, to illustrate the ability of the model to recover basic colony phenomena such as trail formation after food location discovery. We conclude by outlining how the active inference ant colony foraging behavioral model can be extended and situated within a nested multiscale framework and systems approaches to biology more generally.
