🔗 Freedom of speech

The Chicago principles are a set of guiding principles intended to demonstrate a commitment to freedom of speech and freedom of expression on college campuses in the United States. Initially adopted by the University of Chicago following a report issued by a designated Committee on Freedom of Expression in 2014 (″Report of the Committee on Freedom of Expression″), they came to be known as the “Chicago principles”, as the Foundation for Individual Rights in Education (FIRE) led a campaign to encourage other universities across the country sign up to the principles or model their own based on similar goals.

Since 2014, a number of other universities have committed to the principles, including Princeton, Purdue, and Washington University in St. Louis. As of August 2020, FIRE reported that 76 U.S. colleges and universities had "adopted or endorsed the Chicago Statement or a substantially similar statement."

🔗 Biography

Teuvo Kalevi Kohonen (11 July 1934 – 15 December 2021) was a prominent Finnish academic (Dr. Eng.) and researcher. He was professor emeritus of the Academy of Finland.

Prof. Kohonen made many contributions to the field of artificial neural networks, including the Learning Vector Quantization algorithm, fundamental theories of distributed associative memory and optimal associative mappings, the learning subspace method and novel algorithms for symbol processing like redundant hash addressing. He has published several books and over 300 peer-reviewed papers.

Kohonen’s most famous contribution is the Self-Organizing Map (also known as the Kohonen map or Kohonen artificial neural networks, although Kohonen himself prefers SOM). Due to the popularity of the SOM algorithm in many research and in practical applications, Kohonen is often considered to be the most cited Finnish scientist. The current version of the SOM bibliography contains close to 8000 entries.

During most of his career, Prof. Kohonen conducted research at Helsinki University of Technology (TKK). The Neural Networks Research Centre of TKK, a center of excellence appointed by Academy of Finland was founded to conduct research related to Teuvo Kohonen's innovations. After Kohonen's retirement, the center was led by Prof. Erkki Oja and later renamed to Adaptive Informatics Research Centre with widened foci of research.

Teuvo Kohonen was elected the First Vice President of the International Association for Pattern Recognition from 1982 to 1984, and acted as the first president of the European Neural Network Society from 1991 to 1992.

For his scientific achievements, Prof. Kohonen has received a number of prizes including the following:

• IEEE Neural Networks Council Pioneer Award, 1991
• Technical Achievement Award of the IEEE Signal Processing Society, 1995
• IEEE Frank Rosenblatt Award, 2008

El Corte Inglés S.A. (Spanish pronunciation: [el ˈkoɾte iŋˈɡles]), headquartered in Madrid, is the biggest department store group in Europe and ranks third worldwide. El Corte Inglés is Spain's only remaining department store chain. El Corte Inglés has been a member of the International Association of department stores since 1998.

Pyongyang (Chosongul: 평양관) is a restaurant chain named after the capital of North Korea, with around 130 locations worldwide. The restaurants are owned and operated by the Haedanghwa Group, an organization of the government of North Korea.

🔗 International relations 🔗 Food and drink

Culinary diplomacy, gastrodiplomacy or food diplomacy is a type of cultural diplomacy, which itself is a subset of public diplomacy. Its basic premise is that "the easiest way to win hearts and minds is through the stomach". Official government-sponsored culinary diplomacy programs have been established in Taiwan, Thailand, South Korea, Malaysia, Peru, the United States, Cambodia, Japan, Scandinavia, Australia and Uzbekistan.

🔗 Film

Slaughterbots is a 2017 arms-control advocacy video presenting a dramatized near-future scenario where swarms of inexpensive microdrones use artificial intelligence and facial recognition to assassinate political opponents based on preprogrammed criteria. The video was released onto YouTube by the Future of Life Institute and Stuart Russell, a professor of computer science at Berkeley, on 12 November 2017. The video quickly went viral, gaining over two million views. The video was also screened to the November 2017 United Nations Convention on Certain Conventional Weapons meeting in Geneva.

Xsnow is a software application that was originally created as a virtual greeting card for Macintosh systems in 1984. In 1993, the concept was ported to the X Window System as Xsnow, and was included on a number of Linux distributions in the late 1990s.

🔗 Mathematics

In mathematics, Young's lattice is a partially ordered set and a lattice that is formed by all integer partitions. It is named after Alfred Young, who, in a series of papers On quantitative substitutional analysis, developed representation theory of the symmetric group. In Young's theory, the objects now called Young diagrams and the partial order on them played a key, even decisive, role. Young's lattice prominently figures in algebraic combinatorics, forming the simplest example of a differential poset in the sense of Stanley (1988). It is also closely connected with the crystal bases for affine Lie algebras.

SuperH (or SH) is a 32-bit reduced instruction set computing (RISC) instruction set architecture (ISA) developed by Hitachi and currently produced by Renesas. It is implemented by microcontrollers and microprocessors for embedded systems.

At the time of introduction, SuperH was notable for having fixed-length 16-bit instructions in spite of its 32-bit architecture. This was a novel approach; at the time, RISC processors always used an instruction size that was the same as the internal data width, typically 32-bits. Using smaller instructions had consequences, the register file was smaller and instructions were generally two-operand format. But for the market the SuperH was aimed at, this was a small price to pay for the improved memory and processor cache efficiency.

Later versions of the design, starting with SH-5, included both 16- and 32-bit instructions, with the 16-bit versions mapping onto the 32-bit version inside the CPU. This allowed the machine code to continue using the shorter instructions to save memory, while not demanding the amount of instruction decoding logic needed if they were completely separate instructions. This concept is now known as a compressed instruction set and is also used by other companies, the most notable example being ARM for its Thumb instruction set.

As of 2015, many of the original patents for the SuperH architecture are expiring and the SH-2 CPU has been reimplemented as open source hardware under the name J2.

🔗 Spaceflight 🔗 Physics

Electrodynamic tethers (EDTs) are long conducting wires, such as one deployed from a tether satellite, which can operate on electromagnetic principles as generators, by converting their kinetic energy to electrical energy, or as motors, converting electrical energy to kinetic energy. Electric potential is generated across a conductive tether by its motion through a planet's magnetic field.

A number of missions have demonstrated electrodynamic tethers in space, most notably the TSS-1, TSS-1R, and Plasma Motor Generator (PMG) experiments.
