GENETICS Microorganisms can restructure their genomes in response to environmental pressures. When glucose is scarce, budding yeast sequentially acquire mutations that enable “evolved” clones to assimilate glucose more rapidly than their ancestors. Further work has hinted that this capacity is enabled by gene amplification, but other mechanisms may ...

Sublocalization of the breakpoints of a t(5;16) in myelodysplasia
Cancer Genetics and Cytogenetics, 1998As a first step in characterizing a t(5;16)(q31;p11.2) in a patient with the diagnosis refractory anemia with ring sideroblasts, a cell fusion was carried out between bone marrow cells from the patient and the Chinese hamster cell line A3. Using PCR and FISH analysis on hybrid lines containing the human derivative 16 chromosome, the breakpoints could ...

Eyeblink entrainment at breakpoints of speech
Experimental Brain Research, 2010The eyes play an essential role in social communication. Eyeblinks, however, have thus far received minor attention. We previously showed that subjects blink in synchrony while viewing the same video stories (Nakano et al. in Proc R Soc B 276:3635-3644, 2009).

Breakpoint Chlorination Curves of Greywater
Water Environment Research, 2007A study on chlorination of raw greywater with hypochlorite is reported in this paper. Samples were chlorinated in a variety of conditions, and residual chlorine (Cl 2) was measured spectrophotometrically. For each sample, the chlorination curve (chlorine residuals versus chlorine dose) was obtained.

Journal AWWA, 1951
Among other bactericidal agents used in treating water, bromine is sometimes mentioned. Although there are no known applications of bromine to public water supplies, it is finding occasional and increasing use in swimming' pools and industrial water supplies. Because the chemical is used in water conditioning, it was considered desirable to explore its

The Journal of Structured Finance, 2008
This article describes a model that combines the ideas of dynamic continuous credit rating, stress risk analysis, and a probabilistic view of losses. The article defines a breakpoint, a market scenario out of a sorted set that forces a non-agency bond to lose its first dollar of principal; a breakpoint ratio, an estimate of distance to default that is ...

Fast breakpoints: design and implementation
ACM SIGPLAN Notices, 1990We have designed and implemented a fast breakpoint facility. Breakpoints are usually thought of as a feature of an interactive debugger, in which case the breakpoints need not be particularly fast. In our environment breakpoints are often used for non-interactive information gathering; for example, procedure call count and statement ...

The NF1 Translocation Breakpoint Region
Annals of the New York Academy of Sciences, 1991The genetic locus that harbors mutation(s) responsible for neurofibromatosis type 1 (NF1) is on chromosome 17, within band q11.2. We have mapped the human homologue of a murine gene (Evi-2) that is implicated in myeloid tumors, to a location between two NF1 translocation breakpoints on chromosome 17.

Fragile sites and cancer breakpoints
Cancer Genetics and Cytogenetics, 1984To determine whether there might be a statistically significant association between fragile sites and cancer breakpoints, we examined the locations of the 21 fragile sites and the 50 cancer breakpoints recently accepted by the Seventh Human Gene Mapping Workshop. Nine of the 21 fragile sites appeared to be located at or near a cancer breakpoint.

Breakpoints and Concurrent Factors
2017Up to this point, we have articulated a synthesized model of organizational change, and we subsequently detailed some initial findings about the moments at which the organizational configuration of Wikipedia—or the manner in which that configuration was changing over time—shifted.
