However, further sequencing analysis established that these germ line chimera were not present at the earlier time point, as no sequences with the fully mature DJ regions paired to the relevant germ line V genes were detected at t = 54 whereas between 50 and 250 copies of such clones were present at t = 174.

The transit signals were detected in photometric data from the Kepler satellite, and were confirmed to arise from planets using a combination of large transit - timing variations, radial - velocity variations, Warm - Spitzer observations, and statistical analysis of false - positive probabilities.

Nitrogen, in the form of nitric oxide (one nitrogen atom and one oxygen atom), has been detected for the first time on the surface of Mars by a team of researchers using the Sample Analysis at Mars (SAM) instrument suite aboard NASA's Curiosity rover, adding to the growing speculation that life could have once flourished on ancient Mars.

MALDI - MS analysis revealed an absence of Aβ signal in non-transgenic animals (Figure 5) at both time points, indicating that detected Aβ peptides predominantly derive from the human APP transgene expression or reflecting the low level of endogenous rodent Aβ [51].

Aβ38, Aβ39, Aβ40 and Aβ42 peptides were detected in the rat CSF by MALDI - MS analysis even at the plaque - free stages; suggesting that a combination of intracellular and soluble extracellular Aβ may be responsible for impairing cognition at early time points.

Some of the discontinuities (which can be of either sign) in weather records can be detected using jump point analyses (for instance in the new version of the NOAA product), others can be adjusted using known information (such as biases introduced because changes in the time of observations or moving a station).

By contrast, diversification analyses failed to detect evidence for rate - shift changes near the Eocene - Oligocene boundary even though the fossil record provides clear evidence for a major turnover event («Grande Coupure») at this time.

Genome sequence analysis was performed on multiple culture time point samples from six monoclonal isolates, and single nucleotide polymorphism (SNP) variants emerging over time were detected.

These findings underscore the difficulty of detecting non-cultivable B. burgdorferi following antibiotic treatment, as interpretation of xenodiagnosis depends upon timing and number of ticks tested, and the outcome of infection must be measured by analysis of multiple tissues at appropriate intervals.

The Times article goes on to say that The Journal of Communication used computer analysis to show that four linguistic indictors can help detect lying in the personal essay of a dating profile.

Some of the discontinuities (which can be of either sign) in weather records can be detected using jump point analyses (for instance in the new version of the NOAA product), others can be adjusted using known information (such as biases introduced because changes in the time of observations or moving a station).

Mike's work, like that of previous award winners, is diverse, and includes pioneering and highly cited work in time series analysis (an elegant use of Thomson's multitaper spectral analysis approach to detect spatiotemporal oscillations in the climate record and methods for smoothing temporal data), decadal climate variability (the term «Atlantic Multidecadal Oscillation» or «AMO» was coined by Mike in an interview with Science's Richard Kerr about a paper he had published with Tom Delworth of GFDL showing evidence in both climate model simulations and observational data for a 50 - 70 year oscillation in the climate system; significantly Mike also published work with Kerry Emanuel in 2006 showing that the AMO concept has been overstated as regards its role in 20th century tropical Atlantic SST changes, a finding recently reaffirmed by a study published in Nature), in showing how changes in radiative forcing from volcanoes can affect ENSO, in examining the role of solar variations in explaining the pattern of the Medieval Climate Anomaly and Little Ice Age, the relationship between the climate changes of past centuries and phenomena such as Atlantic tropical cyclones and global sea level, and even a bit of work in atmospheric chemistry (an analysis of beryllium - 7 measurements).

It would have to be shown that the recent temperature record can be statistically significantly distinguished from the statistically significant warming signal, which can be detected when performing an analysis that uses data over multiple decades, from the mid-1970ies to present, or from the mid-1970ies up to the time, when the alleged change in the behavior of the global atmospheric temperature is supposed to have occurred.

«Working with data pertaining to 7450 cardiovascular - related deaths that occurred within Budapest, Hungary, between 1995 and 2004 — where the deceased were «medico - legally autopsied» — Toro et al. looked for potential relationships between daily maximum, minimum and mean temperature, air humidity, air pressure, wind speed, global radiation and daily numbers of the heart - related deaths... scientists report and restate their primary finding numerous times throughout their paper, writing that (1) «both the maximum and the minimum daily temperatures tend to be lower when more death cases occur in a day,» (2) «on the days with four or more death cases, the daily maximum and minimum temperatures tend to be lower than on days without any cardiovascular death events,» (3) «the largest frequency of cardiovascular death cases was detected in cold and cooling weather conditions,» (4) «we found a significant negative relationship between temperature and cardiovascular mortality,» (5) «the analysis of 6 - hour change of air pressure suggests that more acute or chronic vascular death cases occur during increasing air pressure conditions (implying cold weather fronts),» (6) «we found a high frequency of cardiovascular death in cold weather,» (7) «a significant negative relationship was detected between daily maximum [and] minimum temperature [s] and the number of sudden cardiovascular death cases,» and (8) «a significant negative correlation was detected between daily mean temperature and cardiovascular mortality.»
