This paper discusses the enrichment of WordNet data through merging of WordNet concepts and Corpus Pattern Analysis (CPA) semantic types. The 253 CPA semantic types are mapped to the respective WordNet concept. As a result of mapping, the hyponyms of a synset to which a CPA semantic type is mapped inherit not only the respective WordNet semantic primitive but also the CPA semantic type.
We employ random matrix theory in order to investigate coherent perfect absorption (CPA) in lossy systems with complex internal dynamics. The loss strength γ_{CPA} and energy E_{CPA}, for which a CPA occurs, are expressed in terms of the eigenmodes of the isolated cavity-thus carrying over the information about the chaotic nature of the target-and their coupling to a finite number of scattering...
Modified fatty acids (mFA) have diverse uses; for example, cyclopropane fatty acids (CPA) are feedstocks for producing coatings, lubricants, plastics and cosmetics. The expression of mFA-producing enzymes in crop and model plants generally results in lower levels of mFA accumulation than in their natural-occurring source plants. Thus, to further our understanding of metabolic bottlenecks that l...
OBJECTIVE This paper examined the relationship between exposure to sexual and physical abuse (CSA and CPA) in childhood and later educational achievement outcomes in late adolescence and early adulthood in a birth cohort of over 1,000 children studied to age 25. METHOD Retrospective data on CSA and CPA were gathered at ages 18 and 21 and used to form a best estimate of exposure to CSA and CPA...
Although CPA (Canonical/Parallel factor Analysis) provides a unique decomposition, the actual computation can be made more robust by incorporating extra constraints. In several applications, the factors in one mode are known to be statistically independent. On the other hand, in Independent Component Analysis (ICA), it often makes sense to impose a Khatri-Rao structure on the mixing vectors. In...
The cytosolic aldehyde dehydrogenase (ALDH) isozyme from cyclophosphamide (CPA) resistant L1210 cells (L1210/CPA) was purified to apparent homogeneity using ternary enzyme complex-dye ligand chromatography. The purified isozyme migrates as a single band at Mr 51,000 in sodium dodecyl sulfate polyacrylamide gel electrophoresis and as a single charge species at isoelectric point = 5.8 in isoelect...
گاز اسیدی شامل مخلوطی از هیدروژن سولفاید، کربن دی اکساید و درصد کمی از هیدروکربن های سبک و بخار آب می باشد و محصول جانبی واحد شیرین سازی گاز است؛ عمده ترین مشکل گازهای اسیدی، آلاینده بودن آن ها و مشکلات محیط زیستی ناشی از دفع آن ها به اتمسفر است. یک روش مناسب برای برطرف کردن این مشکلات، تزریق گاز اسیدی به مخازن است. اگر در مسیر خطوط انتقال گاز و فرآیند تزریق گاز به مخزن، آب موجود در آن میعان یا...
Cyclic phosphatidic acid (cPA), an analog of lysophosphatidic acid (LPA), was previously identified in human serum. Although cPA possesses distinct physiological activities not elicited by LPA, its biochemical origins have scarcely been studied. In the present study, we assayed cPA formation from lysophosphatidylcholine in fetal bovine serum and found significant activity of transphosphatidylat...
BACKGROUND Cyproterone acetate combined with ethinyl estradiol (CPA/EE) provides a treatment option for women with acne, hirsutism or polycystic ovary syndrome (PCOS). CPA/EE may be prescribed as an oral contraceptive (OC), but is not licensed as such in the UK. The use of CPA/EE steadily increased after its introduction to the UK market in 1987, but there was a marked increase in its share of ...
OBJECTIVE To determine the association among signalment, health status, other clinical variables, and treatments and events during cardiopulmonary cerebral resuscitation (CPCR) with the return of spontaneous circulation (ROSC) for animals with cardiopulmonary arrest (CPA) in a veterinary teaching hospital. DESIGN Cross-sectional study. ANIMALS 161 dogs and 43 cats with CPA. PROCEDURES Dat...
