Alexander Lerner
Alexander Yakovlevich Lerner (; 7 September 1913, Vinnytsia, Russian Empire – 6 April 2004, Rehovot, Israel) was a scientist and Soviet refusenik. Biography Early years He was born to a Jewish family in Vinnytsia, Russian Empire (now Ukraine). His father was a pharmacist and had a drugstore. He graduated from a seven-year school in Vinnitsa at age 12 instead of 14, skipping two grades. His school performance was mediocre, as Lerner was more interested in science outside the school program. At the age of 13 he entered the electromechanical college, where he mastered the profession of technician-engineer. Scientific career Lerner graduated with a degree in electrical engineering from the Moscow Power Engineering Institute in 1938, and received a Ph.D. from the same institution in 1940. During World War II, he worked on installing and debugging US equipment at a steel mill in Siberia while it was under construction. In 1943, when the construction was finished, Lerner went ...

Artificial Heart
An artificial heart is a artificial organ, device that replaces the human heart, heart. Artificial hearts are typically used as a bridge to heart transplantation, but ongoing research aims to develop a device that could permanently replace the heart when a transplant—whether from a deceased human or, experimentally, from a genetically engineered pig—is unavailable or not viable. , there are two commercially available full artificial heart devices; both are intended for temporary use (less than a year) for patients with total heart failure who are awaiting a human heart transplant. Although other similar inventions preceded it from the late 1940s, the first artificial heart to be successfully implanted in a human was the Jarvik-7 in 1982, designed by a team including Willem Johan Kolff, William DeVries and Robert Jarvik. An artificial heart is distinct from a ventricular assist device (VAD; for either one or both of the ventricles, the heart's lower chambers), which may als ...

Soviet Electrical Engineers
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a transcontinental country that spanned much of Eurasia from 1922 until it dissolved in 1991. During its existence, it was the largest country by area, extending across eleven time zones and sharing borders with twelve countries, and the third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of national republics, the largest and most populous of which was the Russian SFSR. In practice, its government and economy were highly centralized. As a one-party state governed by the Communist Party of the Soviet Union (CPSU), it was a flagship communist state. Its capital and largest city was Moscow. The Soviet Union's roots lay in the October Revolution of 1917. The new government, led by Vladimir Lenin, established the Russian SFSR, the world's first constitutionally communist state. The revolution was not accepted by all wi ...

Refuseniks
Refusenik (, ; alternatively spelled refusnik) was an unofficial term for individuals—typically, but not exclusively, Soviet Jews—who were denied permission to emigrate, primarily to Israel, by the authorities of the Soviet Union and other countries of the Soviet Bloc. The term ''refusenik'' is derived from the "refusal" handed down to a prospective emigrant from the Soviet authorities. In addition to the Jews, broader categories included: *Other ethnicities, such as Volga Germans attempting to leave for Germany, Armenians wanting to join their diaspora, and Greeks forcibly removed by Stalin from Crimea and other southern lands to Siberia. *Members of persecuted religious groups, such as the Ukrainian Greek Catholic Church, Baptists and other Protestant groups, Jehovah's Witnesses, and Russian Mennonites. A typical basis to deny emigration was the alleged association with Soviet state secrets. Some individuals were labelled as foreign spies or potential seditionist ...

People From Vinnytsia
The term "the people" refers to the public or Common people, common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of Person, persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Declaration on the Rights of Indigenous Peoples, Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independence, independent sovereignty and therefore secession. Indeed, judge Ivor Jennings i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Statistical Learning
Machine learning (ML) is a field of study in artificial intelligence concerned with the development and study of Computational statistics, statistical algorithms that can learn from data and generalise to unseen data, and thus perform Task (computing), tasks without explicit Machine code, instructions. Within a subdiscipline in machine learning, advances in the field of deep learning have allowed Neural network (machine learning), neural networks, a class of statistical algorithms, to surpass many previous machine learning approaches in performance. ML finds application in many fields, including natural language processing, computer vision, speech recognition, email filtering, agriculture, and medicine. The application of ML to business problems is known as predictive analytics. Statistics and mathematical optimisation (mathematical programming) methods comprise the foundations of machine learning. Data mining is a related field of study, focusing on exploratory data analysi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Vladimir Naumovich Vapnik (; born 6 December 1936) is a statistician, researcher, and academic. He is one of the main developers of the Vapnik–Chervonenkis theory of statistical learning and the co-inventor of the support-vector machine method and support-vector clustering algorithms. Early life and education Vladimir Vapnik was born to a Jewish family in the Soviet Union. He received his master's degree in mathematics from the Uzbek State University, Samarkand, Uzbek SSR in 1958 and Ph.D in statistics at the Institute of Control Sciences, Moscow in 1964.
