Original:  We then use it to calibrate the HJM parameters starting from (simulated) option market data. Finally we introduce a new loss function that takes into account bid and ask prices and offers a solution to calibration in illiquid markets . A key issue discovered is that the trained neural network might be non-injective, which could potentially lead to poor accuracy in calibrating the forward curve parameters, even when showing a high degree of accuracy in recovering the prices .
Revised:  We then use it to calibrate the HJM parameters based on observed option prices. We conduct a numerical case study based on artificially generated option prices in a deterministic volatility setting. In this setting we derive closed pricing formulas, allowing us to benchmark the neural network based calibration approach. We also study calibration in illiquid markets . A key issue discovered is that the trained neural network might be non-injective, which could potentially lead to poor accuracy in calibrating the forward curve parameters, even when showing a high degree of accuracy in recovering the prices .

Additionally, the proposed scheme is used for the first-ever numerical demonstration of optical- and radiation-field screening effects on PCD response. The optical-field screening is found to play a more dominant role in the saturation of PCD output at high levels of optical pump power .

We compare the evolution (from January to May 2020 ) of the daily mobilityflows in Italy, measured by means of nation-wide mobile phone data, and the evolution of transmissibility, measured by the net reproduction number, i.e., the mean number of secondary infections generated by one primary infector in the presence of control interventions and human behavioural adaptations.

Original:  This observation allows us to quantify the time needed to "switch off " the country mobility (one week) and the time required to bring the net reproduction number below  1 (one week). A reasonably simple regression model provides evidence that the net reproduction number is correlated with a region's incoming, outgoing and internal mobility. We also find a strong relationship between the number of days above the epidemic threshold before the mobility flows reduce significantly as an effect of lockdowns, and the total number of confirmed SARS-CoV-2 infections per 100k inhabitants , thus indirectly showing the effectiveness of the lockdown and the other non-pharmaceutical interventions in the containment of the contagion .

Original:  In particular, two "new" communities have emerged on Reddit: /r/China _flu and /r/Coronavirus . By studying activities and users in these two communities, we provide a characterization of people's responses to COVID-19 on Reddit . First, we find that user activity peaks around March 17, when the World Health Organization (WHO) announced COVID-19 as a pandemic. Shortly after that, the activity levels of both communities have been declining week by week. We further illustrate the central role of these two communities in the emergence of COVID-related communities.
