Semantic Knowledge Source Integration is an ongoing research project at Cycorp which is developing technologies that enable users to integrate structured knowledge sources in a variety of formats with the Cyc Knowledge Base. Once integrated, the contents of the external sources are available to Cyc for question answering as if the source were “part of” the Knowledge Base. In this paper, we give...

Cyc is the largest existing common-sense knowledge base. Its ontology makes heavy use of higher-order logic constructs such as a context system, first class predicates, etc. Many of these higher-order constructs are believed to be key to Cyc’s ability to represent common-sense knowledge and reason with it efficiently. In this paper, we present a translation of a large part (around 90%) of the C...

Wegener's granulomatosis (WG), the most common of the pulmonary granulomatous vasculitides, typically involves the upper respiratory tract, lower respiratory tract (bronchi and lung), and kidney, with varying degrees of disseminated vasculitis. Major histological features include a necrotizing vasculitis involving small vessels, extensive "geographic" necrosis, and granulomatous inflammation. C...

Shifts in flower symmetry have occurred frequently during the diversification of angiosperms, and it is thought that such shifts play important roles in plant-pollinator interactions. In the model developmental system Antirrhinum majus (snapdragon), the closely related genes CYCLOIDEA (CYC) and DICHOTOMA (DICH) are needed for the development of zygomorphic flowers and the determination of adaxi...

Successful mitosis requires that anaphase chromosomes sustain a commitment to move to their assigned spindle poles. This requires stable spindle attachment of anaphase kinetochores. Prior to anaphase, stable spindle attachment depends on tension created by opposing forces on sister kinetochores [1]. Because tension is lost when kinetochores disjoin, stable attachment in anaphase must have a dif...

The Cyc system has a large knowledge base with detailed knowledge about its concepts. Cyc has axioms and rules for common-sense real-world knowledge embedded in a large taxonomy covering "everything". This is used with Cyc’s logical inference engine to cover medical subject matter in conceptual depth with machine-usable semantics. Cyc’s semantic definitions of relationships are more detailed th...

We had previously demonstrated that the cyc- mutant of S49 wild-type lymphoma cells both desensitizes and undergoes a sequestration-internalization of the beta-receptor in response to short-term treatment with adrenaline. The cyc- mutant of S49 wild-type lymphoma cells lacks the alpha s subunit of the stimulatory coupling protein Ns, but has fully functional Ni, the inhibitory component of the ...

The presence of possible correlations between stellar rotation rate $\Omega$ and the frequency activity cycle $\omega_\mathrm{cyc}$ is still much debated. We implement a new Bayesian classification algorithm based on simultaneous regression analysis multiple scaling laws we demonstrate existence two different scalings in $\log_{10} \omega_\mathrm{cyc}$ -- \Omega$ plane for an extended Mt.~Wilso...

BACKGROUND Scleroderma (SSc) patients with active interstitial lung disease (ILD) experience a decline in lung function and increased mortality; cyclophosphamide (CYC) therapy may stabilize lung function at one and two years follow-up. Long-term lung function and survival outcomes of SSc patients with ILD following CYC treatment remain largely unknown. METHODOLOGY We reviewed records of SSc p...

OBJECTIVE Interstitial lung disease (ILD) frequently complicates systemic sclerosis (SSc). Cyclophosphamide (CYC) is a promising immunosuppressive therapy for SSc-related ILD. Our objective was to investigate the effectiveness of an intravenous CYC (iv CYC) pulse regime in SSc-related ILD during treatment and thereafter. METHODS In a prospective observational study ten consecutive patients wi...
