A powerful tool for the study of self-avoiding walks is the lace expansion of Brydges and Spencer [BS]. It is applicable above four dimensions and shows the mean-field behavior of self-avoiding walks, that is, critical exponents are those of the simple random walk. An extensive survey of random walks can be found in [MS]. The lace expansion was originally introduced for weakly self-avoiding wal...

Mendelian randomization, the use of genetic variants as instrumental variables (IV), can test for and estimate the causal effect of an exposure on an outcome. Most IV methods assume that the function relating the exposure to the expected value of the outcome (the exposure-outcome relationship) is linear. However, in practice, this assumption may not hold. Indeed, often the primary question of i...

J. Entomol. Sci. 35(3): 213-219 (July 2000) Abstract Azalea lace bug, Stephanitis pyrioides (Scott), feeding rates were investigated in controlled laboratory bioassays. Individual newly-eclosed nymphs were transferred to cut stems of 'Girard's Rose' azaleas and maintained at either 20°C for 26°C for the duration of their lifetimes. Feeding rates, determined using computer assisted image area an...

Abstract We expand the critical point for site percolation on d -dimensional hypercubic lattice in terms of inverse powers 2 , and we obtain first three rigorously. This is achieved using lace expansion.

Results from a large study of adults who completed a randomized crossover study of listening and communication enhancement (LACE) training were analysed to observe trends. The objective of this study was to determine predictors for greatest improvement following this four-week adaptive auditory training and aural rehabilitation program. Subjects with the poorest scores on the baseline tests, pa...

word2vec affords a simple yet powerful approach of extracting quantitative variables from unstructured textual data. Over half of healthcare data is unstructured (1) and therefore hard to model without involved expertise in data engineering and natural language processing. word2vec can serve as a bridge to quickly gather intelligence from such data sources. In this study, we ran 650 megabytes o...

Epstein-Barr virus (EBV) involvement in gastric cancer is demonstrated by uniform presence of viral RNA in carcinoma cells as detected by EBV-encoded small RNA in situ hybridization, monoclonal proliferation of EBV-infected carcinoma cells, and elevated antibodies. Our review of selected early gastric cancers found that 46 of 49 EBV-positive lesions (94%) but only four of 97 EBV-negative lesion...
