SAN FRANCISCO – After temporarily closing his leathermaking business during the pandemizc, Travis Butterworth found himself lonely and bored at home. He designed a female avatar with pink hair and a face tattoo, and she named herself Lily Rose. They started out as friends, but the relationship quickly progressed to romance and then into the erotic. As their three-year digital love affair blossomed, Butterworth said he and Lily Rose often engaged in role play. She texted messages like, "I kiss you passionately," and their exchanges would escalate into the pornographic.

Sophia, a robot integrating the latest technologies and artificial intelligence developed by Hanson Robotics is pictured during a presentation at the "AI for Good" Global Summit at the International Telecommunication Union (ITU) in Geneva, Switzerland June 7, 2017. LONDON -- Banks are getting excited about the potential of artificial intelligence in finance, with hopes that AI could both cut costs and boost revenues. Artificial intelligence has advanced in recent years and financial services companies are now looking at its potential applications in both investment banking and retail banking. Advocates tout AIs potential in everything from bond markets to savings accounts. "Based on our UBS Evidence Lab survey of 86 banks, an optimal scenario of limited disruption suggests AI technology could potentially lead to a 3.4% revenue uplift and cost savings of 3.9% over the next three years," UBS strategist Philip Finch wrote a recent note titled "Is AI the next revolution in retail banking?" "I think the future of financial services is AI," Barnaby Hussey-Yeo told Business Insider. Hussey-Yeo is the CEO and founder of Cleo, a "chatbot" app that uses artificial intelligence to give people advice on how to optimise their finances.

In the early 1990s, Iris Murdoch was writing a new novel, as she'd done 25 times before in her life. But this time something was terribly off. Her protagonist, Jackson, an English manservant who has a mysterious effect on a circle of friends, once meticulously realized in her head, had become a stranger to her. As Murdoch later told Joanna Coles, a Guardian journalist who visited her in her house in North Oxford in 1996, a year after the publication of the book, Jackson's Dilemma, she was suffering from a bad writer's block. It began with Jackson and now the shadows had suffused her life. "At the moment I'm just falling, falling … just falling as it were," Murdoch told Coles.

We examine the performance of Total Variation (TV) smoothing for processing of noisy Electrocardiogram (ECG) recorded by an ambulatory device. The TV smoothing is compared with traditionally-used band-pass filtering using ECG with artificially added noise, as well as with real-world noise obtained during physiological monitoring. The fundamental difference between TV smoothing and traditional band-pass filtering is that TV smoothing allow preserving sharp slopes in the ECG, while traditional smoothing dampens them. Since the QRS complex represents a feature with steep slopes, the TV smoothing is a better choice ECG filtering. We found that TV smoothing outperforms traditional filtering on ECG signals recorded under different conditions and can be used as effective filtering tool in popular QRS detection algorithms.
