Purchasing Power Parity (PPP) is the measurement of prices in different countries that uses the prices of specific goods to compare the absolute purchasing power of the countries' currencies. In many cases PPP produces an inflation rate that is equal to the price of the basket of goods at one location divided by the price of the basket of goods at a different location. The PPP inflation and exchange rate may differ from the market exchange rate because of poverty, tariffs, and other transaction costs.

Qajar dynasty Iranian royal dynasty of Turkic origin

The Qajar dynasty was an Iranian royal dynasty of Turkic origin, specifically from the Qajar tribe, ruling over Iran from 1789 to 1925. The Qajar family took full control of Iran in 1794, deposing Lotf 'Ali Khan, the last Shah of the Zand dynasty, and re-asserted Iranian sovereignty over large parts of the Caucasus. In 1796, Mohammad Khan Qajar seized Mashhad with ease, putting an end to the Afsharid dynasty, and Mohammad Khan was formally crowned as Shah after his punitive campaign against Iran's Georgian subjects. In the Caucasus, the Qajar dynasty permanently lost many of Iran's integral areas to the Russians over the course of the 19th century, comprising modern-day Georgia, Dagestan, Azerbaijan and Armenia.

Giovanni Paolo Panini Italian painter (1691-1765)

Giovanni Paolo Panini or Pannini was a painter and architect who worked in Rome and is primarily known as one of the vedutisti. As a painter, Panini is best known for his vistas of Rome, in which he took a particular interest in the city's antiquities. Among his most famous works are his view of the interior of the Pantheon, and his vedute—paintings of picture galleries containing views of Rome. Most of his works, especially those of ruins, have a fanciful and unreal embellishment characteristic of capriccio themes. In this they resemble the capricci of Marco Ricci. Panini also painted portraits, including one of Pope Benedict XIV.

Homestay Form of hospitality and lodging

Homestay is a popular form of hospitality and lodging whereby visitors share a residence with a local of the city to which they are traveling. The length of stay can vary from one night to over a year and can be provided gratis, in exchange for monetary compensation, in exchange for a stay at the guest's property either simultaneously or at another time, or in exchange for housekeeping or work on the host's property. Homestays are examples of collaborative consumption and the sharing economy.

In cryptography, a public key exchange algorithm is a cryptographic algorithm which allows two parties to create and share a secret key, which they can use to encrypt messages between themselves. The ring learning with errors key exchange (RLWE-KEX) is one of a new class of public key exchange algorithms that are designed to be secure against an adversary that possesses a quantum computer. This is important because some public key algorithms in use today will be easily broken by a quantum computer if such computers are implemented. RLWE-KEX is one of a set of post-quantum cryptographic algorithms which are based on the difficulty of solving certain mathematical problems involving lattices. Unlike older lattice based cryptographic algorithms, the RLWE-KEX is provably reducible to a known hard problem in lattices.

Prince is a block cipher targeting low latency, unrolled hardware implementations. It is based on the so-called FX construction. Its most notable feature is the "alpha reflection": the decryption is the encryption with a related key which is very cheap to compute. Unlike most other "lightweight" ciphers, it has a small number of rounds and the layers constituting a round have low logic depth. As a result, fully unrolled implementation are able to reach much higher frequencies than AES or PRESENT. According to the authors, for the same time constraints and technologies, PRINCE uses 6–7 times less area than PRESENT-80 and 14–15 times less area than AES-128.
