 an exponentially decaying function of d, such that κ e = A exp(−γ(d − C)) with fitting parameters, A = 4.1504, γ = 14.12892 µm −1 and C = 0.12553µm. Similarly, an independent experimental measurement was taken for the optical mode spectral position for different coupling gaps. The derivative of the above yields a reconstructed dispersion relation, which is an exponentially rising function of d, as g = g′ exp(−ζd), where g′/2π = 58.515 MHz and ζ = 12 µm −1 are the fitting parameters. The intrinsic loss, κ 0, was estimated from the optical line width of the WGM when it was far undercoupled, so that κ 0 /2π ≈ 13 MHz. We found that, by considering the coupling ideality, a better fit to the curves could be obtained, especially for the critically coupled and overcoupled regimes, when the fiber taper scattered significant amounts of light. In order to determine the profile of the normalized total decay rate, κ t, the loaded Q-factor (given by 1/Q = 1/Q 0 + 1/Q e + 1/Q s ) was measured at different coupling gaps. With κ e as mentioned above, the scattering rate can be calculated from κ s = κ t − κ e − 1.
The calculated κ s was fitted with an exponentially decaying profile as a function of d, similar to κ e. To introduce the pendulum dynamics, d = d 0 + δd cos (Ω m t), was substituted in to the generalized functions κ e, g and κ s and were then substituted into Eq. 2, which was also used to plot Fig. 2. For Fig. 3, the coupling conditions varied from undercoupled ( Fig.3(a)) to overcoupled (Fig.3(c)).
To fit them, approximated coupling gaps to theoretical euilibrium ones were chosen. We then plotted all detuned maxima of the response curves for coupling gaps ranging from 0.1 to 0.45 µm with the respective theoretical prediction curves presented Fig. 4. Good agreement with experiments is evident. The discrepancies in the fit may originate from (i) the difficulty in controlling the coupling gap, leading to errors on this value, (ii) an excessive noise level in the low frequency FFT spectrum, (iii) thermal fluctuations, and (iv) laser noise. Regardless of these sources of error, both theory and experiments show a maximum transduction for red detuning at the critical coupling gap, which is depicted as the dashed line in Fig.  4, and a clear contrast between the detuned transductions.
In conclusion, the optomechanical transduction of a micropendulum taper system was measured using weak probe light. Large displacements of the mechanical oscillations modulated the WGMs both dissipatively and dispersively. This, in turn, affected the transmission through the fiber. A model based on coupled mode theory and FFT explained the experimentally-observed, WGM detuned asymmetric response quite well. Maxi-mum sensitivity for probing the system requires that the system operate under the critically coupled condition with the laser properly red-detuned from the WGM resonances. This transduction mechanism, which is by now well understood, can provide a foundation for future work on cooling and trapping of a micropendulum [4,[27][28][29] and optomechanical sensing applications [30].

With a vaccination rate of 1.5 million vaccinations per week, it won’t take long until children below 17 years old can be vaccinated. Last week, the Dutch Health Counsel advised to vaccinate 12-to-17-year old’s with health issues, with the expectation that this advice will soon be extended to healthy children. Countries such as Germany, France and Canada already reached this point -- children from the age of 12 can get a COVID-19 vaccination. China allows children from the age of 3 to get vaccinated against COVID-19. However, it will be the parents that ultimately decide on the vaccination of their children. In that case the choice should be relatively simple, as parents already decided for themselves on whether to get “vaxed.” But is vaccinating yourself truly the same as vaccinating your child?
We investigated the decision to get a vaccination for a hypothetical, relatively unknown and uncertain disease, with comparable features of the COVID-19 virus. The risks of the disease and the (potentially severe) side-effects were proposed to be the same for children and adults. A priori, we expected participant’s preferences to be rational and consistent over time, leading to the same vaccination decision for their child as for themselves. Interestingly, we find that adults are 28% more likely to accept the vaccine for their child, as compared to likelihood of getting vaccinated themselves.
Trying to understand this discrepancy, we find that the underlying levels of expected regret towards making the wrong choice played an important role. We measured two types of regret: 1) the experienced regret when getting the disease without vaccination, and 2) the experienced regret when experiencing the side-effects after vaccination. Figure 1 shows our results: first, people overall experience higher levels of both types of regret when making the choice to vaccinate their child (Panel B) than for themselves (Panel A). Second, most predominately, we see a trend that the experienced regret after getting the disease without vaccination is higher when it pertains your children compared to yourself. Even for people that decided to vaccinate themselves anyway, the regret after getting the disease without vaccination is less (Panel A, blue, y-axis), compared to the same regret when vaccinating their children (Panel B, blue, y-axis).
What do these findings imply? First, fear and regret are important drivers of the decision to get vaccinated. Second, the levels of regret differ when we make the decision for ourselves compared to our children.  People are more willing to vaccinate their child than themselves, according to our findings. Emphasizing and focusing on the risks and consequences of both the side-effects of the vaccination as well as a COVID-19 infection, specifically for children, could promote an optimal decision process. Our findings are optimistic: even parents that might be willing to take the risk of a COVID-19 infection themselves, seem to be hesitant to take the same risk with their children.

Stanley Maslowski, of East Granby, was driving a Toyota Tacoma pickup truck northbound on Route 318 when he tried to avoid a black bear that was crossing the northbound lane, according to a state police report.
After striking the bear, Maslowski then sideswiped a Volvo S60 traveling southbound, police said. Gilbert Macconnell, 48, was driving the Volvo, which was forced into the wire rope guide rails off of the right shoulder of the southbound lane, police said.
Maslowski’s car eventually overturned and came to a final rest on its left side facing southbound in the southbound lane.
Both men were transported by New Hartford Volunteer Ambulance to Winsted Health Center for treatment. Maslowski suffered left foot and lower back pain, police said. Macconnell had minor abrasions, according to the report.
Dwayne Gardner, spokesman for the state Department of Energy and Environmental Protection Agency said the bear died from its injuries.
Gardner said that there are a couple dozen bears killed by cars a year in Connecticut.
He recommends that drivers show extra caution when driving in areas where bears are more active, particularly at dusk and dawn. Gardner reports that so far this year there have been 64 bear sightings in Barkhamsted, 96 in New Hartford and 203 in Torrington.
“When you see a bear you should report it the DEEP,” said Gardner.
He recommends that if there is a bear repeatedly visiting a yard that’s been bear-proofed, call the DEEP and they will use adverse conditioning methods to get the bear to not return to your property. If the adverse conditioning methods fail to keep the bear off the property then they will tranquilize and relocate it.
Route 318, also known as Ripley Hill Road, was reopened by 6:20 p.m. after being closed at about 5:30 p.m., the state Department of Transportation said.
