However, genetic manipulation of SSCs has met with limited success. Here, we show efficient gene transfer into SSCs via a lentivirus (FV-LV) using a fusion protein (F), a Sendai virus (SV) envelope protein involved in virion/cell membrane .

Both mechanical watches and quartz watches tick, but quartz watches tick in a much more distinct way, with one tick per second, whereas mechanical movement ticks at 8 to 10 times per second, creating a sweeping effect of the second hand.

Many high-quality mechanical watches have this feature.
Rolex watches have a second hand that appears to glide through the dial rather than tick-tock. It’s not restricted to the brand, nor is it a novelty. All mechanical watches tick at varying frequencies, including dirt-cheap ones, which are typically faster than quartz. The balance wheel, a crucial component of the movement, is responsible for the signature sweeping motion of the Rolex second hand. It oscillates back and forth at a consistent rate, typically eight times per second (28,800 vibrations per hour).
Higher frequencies sliced the second into smaller portions, creating a smoother "sweep" and thus the perceived smoothness of the second hand became a shortcut to interpreting the quality of the movement. I just looked at my friends Rolex and I noticed his second hand sweeps but it kinda ticks. Not a smooth sweep at all. I just received my Rolex today and noticed that mine sweeps pretty smoothly. Barely ticking! Does this mean his is fake or .

The beat rate varies with the movement. Even the latest movements are 28,800 bph, so the second hand actually moves 8 times per second. Here are some Rolex movement beat rates: caliber 3035 & 3055: 28,800 bph. caliber 1800,1401 1220 1225: 21,600 bph.
Genuine Rolex watches have a smooth sweeping second hand – and copies do not. They have more of a jittery motion. But not everyone knows why this is. Modern Rolex watches beat away at 4hz – which is 28,800 vph or – VIBRATIONS PER HOUR. A watch ticking at 4Hz makes 4 oscillations per second, or 8 semi-oscillations (or vibrations) per second. Although ticking is generally meant to mean one movement per second, claiming a seconds hand that moves twice per second is sweeping would seem a bit of a stretch of the imagination. At best you could call that a stuttering sweep, or a high-frequency tick. Quartz watches with second hands smoother than 1-tick-per-second. Quick note: A “sweep second hand” actually means a second hand that is in the center of the dial (rather than in a subdial). This was a complication in early watches, since it required an extra intermediate wheel.
