O-linked beta-N-acetylglucosamine (O-GlcNAc) is both an abundant and dynamic posttranslational modification similar to phosphorylation that occurs on serine and threonine residues of cytosolic and nuclear proteins in all metazoans and cell types examined, including cardiovascular tissue. Since the discovery of O-GlcNAc more than 20 years ago, the elucidation of O-GlcNAc as a posttranslational m...

In the last decade a variety of methodologies for representing and evaluating knowledge qualitatively has been developed, particularly within the field of Artificial Intelligence. Qualitative reasoning methodologies represent an alternative to quantitative modeling approaches, if the knowledge about the system of interest is imprecise or incomplete, as it is often the case when dealing with eco...

in recent years, it has become increasingly important to incorporate explicit dynamics in economic analysis. these two tools that mathematicians have developed, differential equations and optimal control theory, are probably the most basic for economists to analyze dynamic problems. in this paper i will consider the linear differential equations on the plane (phase diagram) and elements of nonl...

The main purpose of this work is to introduce the class of the monadic dynamic algebras (dynamic algebras with one quantifier). Similarly to a theorem of Kozen we establish that every separable monadic dynamic algebra is isomorphic to a monadic (possibly non-standard) Kripke structure. We also classify the simple (monadic) dynamic algebras. Moreover, in the dynamic duality theory, we analyze th...

Nanotechnology has a great influence on modern technology, just like the development of DNA profiling on biotechnology in the past 50 years. Because of applying knowledge and techniques from natural science, forensic science aims to identify, individualize and evaluate evidence. Evidence will then be used to reconstruct crime scenes, guide investigations and bring criminals to justice. Nanotech...

Merger and Acquisitions (M&As) provide a plausibly exogenous shock to analysts’ decision to drop, add or maintain coverage of the merged firms. Higher caliber analysts covering the acquiring and target firms before the M&A deal are more likely to cover the merged firm. The majority of target analysts drop coverage of the merged firm following the delisting of the target stock. However, the targ...

Applications should be an invaluable experimental source of information and challenges for AI research. The real world always stretches the limitations of our AI systems, pointing toward new research themes in many areas. In the process of implementing an application, the designer continually makes choices based on (1) the baseline architecture used to implement the application, (2) the charact...

We study how M&As shape analysts’ coverage decisions and whether this process reveals information about the valuation and future performance of the merged firms. Since the target firm is delisted after the M&A, we expect and find that the majority of the analysts covering the target drop their coverage of the merged firm. However, the target analysts who retain coverage provide the most accurat...
