One of the most problematic devices, the A.S.R., or Articular Surface Replacement, was recalled last year by Johnson & Johnson and accounted for 75 percent of the complaints reviewed by The Times.
Some of the country's biggest carriers have taken notice of concern around the fiery phablets, issuing plans designed to let consumers trade their Notes in for less problematic devices while Samsung and the U.S. Consumer Product Safety Commission attempt to figure out what the heck is going on with the devices intended to replace that earlier bunch.
"Companies have dumped these costs into the health care system," said Dr. Lawrence D. Dorr, an orthopedic surgeon in Los Angeles who two years ago took the unusual step of drawing attention to one problematic hip device.
Limiting nonspecific interaction of cells, proteins, and microorganisms with material surfaces is critical, since these interactions can prove highly problematic for device efficacy and safety.
While the short-term road ahead should not be too problematic for device makers, all signs point to a make it or break it moment in a few years' time.
The large openings in a MNW network could be problematic for some device applications when the charge diffusion path length is less than the hole size.
That's no surprise, but he has more to say, suggesting that while "great journalism can be supported in print" with a combination of sales and advertising, the web remains problematic, and mobile devices even more so.
This is problematic for many devices, especially ones that consist of thin layers.
Active cooling of thermoelectric generators (TEGs) is problematic since mechanical devices such as pumps and fans draw a high proportion of the limited power generated.
In our hands uniform parafilm adherence was problematic so these devices tended to leak.
This can make experiments such as the study of molecular motor stepping[8], [9] or forced unfolding[10] problematic in such devices.
