Recently, acceptor-donor-acceptor (A-D-A) type of small molecules based on indacenodithieno[3,2-b]thiophene (IDTT) or indacenodithiophene (IDT) as the electron-donating cores were very promising non-fullerene (NF) acceptors to overcome the energy levels and absorption drawbacks of the fullerene-based acceptors in polymer solar cells (PSCs).
Even blood testing of hormone levels has the drawback that levels vary throughout the day as well as from day to day.
Unavailability of macroprolactin levels was another drawback.
Measuring the night time exposure levels is another drawback of the used dosimeter.
They have drawbacks: higher levels of testosterone might increase the risk of prostate cancer or have knock-on behavioural effects (anabolic steroids, which mimic testosterone in the body, have been linked to "roid rage").
The main focus of this investigation is on the consequences of raising the maximum operating temperature of IGBT modules and the required design modifications of solder materials at a microstructure level for tackling the drawbacks of state-of-the-art technologies.
Working with population-level data has its drawbacks, as the loss of synchrony during a time course will confound any measurements: due to synchrony loss, each time point represents a mixture of cells at different positions in the cell cycle.
To determine whether other markers may compensate for this drawback, serum levels of CA50, Span-1, sialyl SSEA-1 and Dupan-2 were assayed and compared with those of CA19-9 in 207 normal subjects and in 200 patients with pancreatic carcinoma whose Lewis blood group phenotypes were confirmed.
However, multi-level caching policies deployed so far typically use independent cache replacement algorithms in each level, which has two major drawbacks: (1) File blocks may be redundantly cached on multiple levels, reducing the actual aggregate cache usable size; (2) Less accurate replacement decisions at lower level caches due to weakened locality.
When studying the proteome at an individual level, a common drawback in the data analysis is that the distribution of the studied variables (protein abundance measured as spot volume) is unknown.
