Phase-locked two-color soliton microcombs
No full textWe design a dispersion-engineered Si3N4 microresonator to support two-color soliton states. The directly-pumped 1550 nm soliton is phase-locked to a second color whose center wavelength can be tailored between 750 nm to 3000 nm

Vigiliae Christianae, Supplements, Volume: 150In this paper I want to take you on a walk through a garden. It is, to be sure, an imaginary garden; nevertheless, it bears a significance which extends beyond itself. Some of this significance concerns words and texts: for as we shall see, the garden is, amongst other things, a ‘garden of rhetoric’. The garden in question appears in the Gregory of Nyssa’s Homilies on the Song of Songs.[...
An Evening with Richard Claxton “Dick” Gregory, Civil Rights Activist, Nutritionist, Comedian, and Author
Full text linkGregory, Richard Claxton “Dick” (Born, October 12, 1932, St. Louis, Mo.), African American comedian and civil rights activist whose social satire changed the way white Americans perceived African American comedians since he first performed in public. Gregory’s autobiography, Nigger, was published in 1963 prior to The assassination of President Kennedy, and became the number one best-selling book in America. Over the decades it has sold in excess of seven million copies. His choice for the title was explained in the forward, where Dick Gregory wrote a note to his mother. “Whenever you hear the word ‘Nigger’,” he said, “you’ll know their advertising my book.” In 1984 he founded Health Enterprises, Inc., a company that distributed weight loss products. In 1987 Gregory introduced the Slim-Safe Bahamian Diet, a powdered diet mix, which was immensely profitable. Economic losses caused in part by conflicts with his business partners led to his eviction from his home in 1992. Gregory remained active, however, and in 1996 returned to the stage in his critically acclaimed one-man show, Dick Gregory Live! The reviews of Gregory’s show compared him to the greatest stand-ups in the history of Broadway
“Judge Me Gently”: Reflections on the Religious Life of John Milton Gregory, 1822–1898
No full text John Milton Gregory is familiar to many Christian educators through his 19th-century publication, The Seven Laws of Teaching. For most readers of this important book, little is known about the author himself. This article explores the religious life and theological foundations of John Milton Gregory, who was both author of The Seven Laws of Teaching and founding president of the University of Illinois. Utilizing his spiritual diaries preserved in his daughter's biography of her father and archival sources from the University of Illinois, this essay offers a theological and spiritual understanding of this important historical figure. </jats:p

Attention mechanisms for broadband feature prediction for electromagnetic and photonic applications
No full textSPIE Optical Engineering + Applications, August 20-24 2023, San Diego, California, United StatesWe present a study on the accuracy of three neural network architectures, namely fully-connected neural networks, recurrent neural networks, and attention-based neural networks, in predicting the coupling response of broadband microresonator frequency combs. These frequency combs are crucial for technologies like optical atomic clocks. Optimizing their spectral features, especially the dispersion in coupling to an access waveguide, can be computationally demanding due to the large number of parameters and wide spectral bandwidths involved. To address this challenge, we employ machine learning algorithms to estimate the coupling response at wavelengths not present in the input training data. Our findings demonstrate that when trained with data sets encompassing the upper and lower limits of each design feature, attention mechanisms achieve over 90% accuracy in predicting the coupling rate for spectral ranges six times wider than those used in training. This significantly reduces the computational burden for numerical optimization in ring resonator design, potentially leading to a six-fold reduction in compute time. Moreover, devices with strong correlations between design features and performance metrics may experience even greater acceleration.Gregory Moille and Kartik Srinivasan acknowledge support from the NIST-on-a-chip and DARPA APHI programs.
