Jörg Wolfgang Demus (2 December 1928 – 16 April 2019) was an Austrian classical pianist who appeared internationally and made many recordings. He was also a composer and a lecturer at music academies. In composition and playing, he focused on chamber music and lieder. He played with singers such as Elisabeth Schwarzkopf and Dietrich Fischer-Dieskau, as a piano duo with Paul Badura-Skoda, and with string players such as Josef Suk and Antonio Janigro. Demus was instrumental in bringing the historic fortepiano to concert podiums. He was a member of the Legion of Honour, among many awards. He is regarded as one of the leading Austrian pianists of the immediate post-World War II era.

Tu Tu Main Main (English: Squabble) is an Indian sitcom television sitcom which originally aired on DD Metro and later STAR Plus directed by Sachin Pilgaonkar. The series first premiered on DD Metro in 1994 till 1996 before it moved to Star Plus and the series went on to become the first show to launch the STAR Plus Hindi Band in October 1996. It was dubbed in Tamil as Bhama Vijayam on Raj TV . A sequel series with same themes and extended cast, also directed by Sachin. Kadvee Khattee Meethi aired on STAR One in 2006.

Doubochinski's pendulum is a classical oscillator interacting with a high-frequency field in such a way that the oscillator takes on a discrete set of stable regimes of oscillation, each at a frequency near to the proper frequency of the oscillator, but each with a distinct, "quantized" amplitude. The phenomenon of amplitude quantization in this sort of coupled system was first discovered by the brothers Danil and Yakov Doubochinski in 1968–69.

Ifni was a Spanish province on the Atlantic coast of Morocco, south of Agadir and across from the Canary Islands. It had a total area of 1,502 km² (580 sq mi), and a population of 51,517 in 1964. The main industry was fishing. The present-day Moroccan province in the same area is called Sidi Ifni, with its capital in the city of the same name, but encompassing a much larger territory.

WWE NXT, also known as Tuesday Night NXT or simply NXT, is a professional wrestling television program. It is produced by the American professional wrestling promotion WWE, featuring performers from the promotion's NXT brand division. The show currently airs live on Tuesdays at 8 pm ET on the USA Network. NXT initially debuted in 2010 as a seasonal show which was presented as a hybrid between WWE's scripted live event shows and reality television, in which talent from WWE's developmental territory Florida Championship Wrestling (FCW) participated in a competition to become WWE's next "breakout star", with the help of mentors from WWE's Raw and SmackDown brands. Five seasons of this iteration were broadcast, with Wade Barrett, Kaval, Kaitlyn, and Johnny Curtis being announced as winners. In June 2012, WWE ended the seasonal competition format and opted to revamp the show. WWE NXT became the flagship television show of the NXT brand, and has since received a positive reception and high viewership, with praise for its high quality of wrestling and captivating storylines. Many consider NXT to be superior to WWE's flagship shows. The initial version of the show made its debut on Syfy on February 23, 2010, replacing ECW, but was replaced by SmackDown in October. It then aired as an hourly webcast on WWE.com on the United States until June 13, 2012, before it was expanded to international markets on the WWE Network in 2014. In 2019, NXT expanded into a live two-hour program on the USA Network.

Doubochinski's pendulum is a classical oscillator interacting with a high-frequency field in such a way that the oscillator takes on a discrete set of stable regimes of oscillation, each at a frequency near to the proper frequency of the oscillator, but each with a distinct, "quantized" amplitude. The phenomenon of amplitude quantization in this sort of coupled system was first discovered by the brothers Danil and Yakov Doubochinski in 1968–69. A simple demonstration apparatus consists of a mechanical pendulum interacting with a magnetic field (Fig. 1). The system is composed of two interacting oscillatory processes: a pendulum arm with a natural frequency on the order of 0.5–1 Hz, with a small permanent magnet fixed at its moving end; and a stationary electromagnet (solenoid) positioned under the equilibrium point of the pendulum's trajectory and supplied with alternating current of fixed frequency, typically in the range of 10–1000 Hz. The mechanical pendulum arm and solenoid are configured in such a way, that the pendulum arm interacts with the oscillating magnetic field of the solenoid only over a limited portion of its trajectory – the so-called "zone of interaction" – outside of which the strength of the magnetic field drops off rapidly to zero. This spatial inhomogeniety of the interaction is key to the quantized behavior and other unusual properties of the system. When released at any arbitrary starting position, the pendulum's motion evolves into one of a discrete set of stable oscillation modes, having sharply differing amplitudes, but approximately the same period of oscillation – close to the pendulum's undisturbed period (Fig. 2). In each such mode, the energy lost by friction in the pendulum's motion, is compensated by an average net energy transfer from the oscillating magnetic field, in a self-regulating manner. The stability of each amplitude-mode is maintained by a constant self-adjustment of the phase relationship between the pendulum and the high-frequency field. Through its interaction with the field, the pendulum extracts the amount of energy needed to compensate its frictional losses for a given period. The pendulum compensates for the changes in the strength of the magnetic field,by slightly shifting the phase of its entry into the zone of interaction, while maintaining almost exactly the same amplitude and frequency. The values of the quantized amplitudes – and the corresponding energies of the quantized modes – are essentially independent of the strength of the alternating current supplied to the electromagnet, over a very large range. The higher the applied frequency, the larger the array of stable modes that become accessible to the pendulum (See Table 1).
