The White House Reconstruction, also known as the Truman Reconstruction, was a comprehensive dismantling and rebuilding of the interior of the White House from 1949 to 1952. A century and a half of wartime destruction and rebuilding, hurried renovations, additions of new services, technologies, the added third floor and inadequate foundations brought the Executive Residence portion of the White House Complex to near-imminent collapse.

In 1948, architectural and engineering investigations deemed it unsafe for occupancy. President Harry S. Truman, his family, and the entire residence staff were relocated across the street to Blair House. For over three years, the White House was gutted, expanded, and rebuilt.

The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. Stimuli, like stress, improved memory when it was related to learning the subject. During times of stress, the body reacts by secreting stress hormones into the bloodstream. Stress can cause acute and chronic changes in certain brain areas which can cause long-term damage. Over-secretion of stress hormones most frequently impairs long-term delayed recall memory, but can enhance short-term, immediate recall memory. This enhancement is particularly relative in emotional memory. In particular, the hippocampus, prefrontal cortex and the amygdala are affected. One class of stress hormone responsible for negatively affecting long-term, delayed recall memory is the glucocorticoids (GCs), the most notable of which is cortisol. Glucocorticoids facilitate and impair the actions of stress in the brain memory process. Cortisol is a known biomarker for stress. Under normal circumstances, the hippocampus regulates the production of cortisol through negative feedback because it has many receptors that are sensitive to these stress hormones. However, an excess of cortisol can impair the ability of the hippocampus to both encode and recall memories. These stress hormones are also hindering the hippocampus from receiving enough energy by diverting glucose levels to surrounding muscles.

Stress affects many memory functions and cognitive functioning of the brain. There are different levels of stress and the high levels can be intrinsic or extrinsic. Intrinsic stress level is triggered by a cognitive challenge whereas extrinsic can be triggered by a condition not related to a cognitive task. Intrinsic stress can be acutely and chronically experienced by a person. The varying effects of stress on performance or stress hormones are often compared to or known as "inverted-u" which induce areas in learning, memory and plasticity. Chronic stress can affect the brain structure and cognition.

Studies considered the effects of both intrinsic and extrinsic stress on memory functions, using for both of them Pavlovian conditioning and spatial learning. In regard to intrinsic memory functions, the study evaluated how stress affected memory functions that was triggered by a learning challenge. In regard to extrinsic stress, the study focused on stress that was not related to cognitive task but was elicited by other situations. The results determined that intrinsic stress was facilitated by memory consolidation process and extrinsic stress was determined to be heterogeneous in regard to memory consolidation. Researchers found that high stress conditions were a good representative of the effect that extrinsic stress can cause on memory functioning. It was also proven that extrinsic stress does affect spatial learning whereas acute extrinsic stress does not.

The Welrod is a British bolt-action, magazine-fed pistol with an integrated silencer which was devised for covert operations during the Second World War by Major Hugh Reeves at the Inter-Services Research Bureau (later Station IX).

Station IX, being based in Welwyn, gave the Welrod its unusual name, being derived from "Wel" from "Welwyn" (a prefix used by covert equipment designed by Station IX) and "rod", gangland slang for gun, as a way to obscure its purpose.

Designed for use by irregular forces and resistance groups, the Welrod is an extremely quiet gun thanks to its integrated silencer. Approximately 2,800 were made in wartime and perhaps 14,000 in total when post-war examples are included.

🔗 Law

Jury nullification, also known in the United Kingdom as jury equity, or a perverse verdict, is when the jury in a criminal trial gives a verdict of not guilty even though they think a defendant has broken the law. The jury's reasons may include the belief that the law itself is unjust, that the prosecutor has misapplied the law in the defendant's case, that the punishment for breaking the law is too harsh, or general frustrations with the criminal justice system. Some juries have also refused to convict due to their own prejudices in favor of the defendant. Such verdicts are possible because a jury has an absolute right to return any verdict it chooses. Nullification is not an official part of criminal procedure but is the logical consequence of two rules governing the systems in which it exists:

1. Jurors cannot be punished for passing an incorrect verdict.
2. In many jurisdictions, a defendant who is acquitted cannot be tried a second time for the same offense.

A jury verdict that is contrary to the letter of the law pertains only to the particular case before it; however, if a pattern of acquittals develops in response to repeated attempts to prosecute a particular offence, this can have the de facto effect of invalidating the law. Such a pattern may indicate public opposition to an unwanted legislative enactment. It may also happen that a jury convicts a defendant even if no law was broken, although such a conviction may be overturned on appeal. Nullification can also occur in civil trials; unlike in criminal trials, if the jury renders a not liable verdict that is clearly at odds with the evidence, the judge can issue a judgment notwithstanding the verdict or order a new trial.

World on a Wire (German: Welt am Draht) is a 1973 West German science fiction television serial, starring Klaus Löwitsch and directed by Rainer Werner Fassbinder. Shot in 16 mm, it was made for West German television and originally aired in 1973 in ARD as a two-part miniseries. It was based on the 1964 novel Simulacron-3 by Daniel F. Galouye. An adaptation of the Fassbinder version was presented as the play World of Wires, directed by Jay Scheib, in 2012.

Its focus is not on action, but on sophistic and philosophic aspects of the human mind, simulation, and the role of scientific research. A movie based on the same novel titled The Thirteenth Floor starring Craig Bierko was released in 1999.

NeuroEvolution of Augmenting Topologies (NEAT) is a genetic algorithm (GA) for the generation of evolving artificial neural networks (a neuroevolution technique) developed by Kenneth Stanley and Risto Miikkulainen in 2002 while at The University of Texas at Austin. It alters both the weighting parameters and structures of networks, attempting to find a balance between the fitness of evolved solutions and their diversity. It is based on applying three key techniques: tracking genes with history markers to allow crossover among topologies, applying speciation (the evolution of species) to preserve innovations, and developing topologies incrementally from simple initial structures ("complexifying").

Slop is low-quality media—including writing and images—made using generative artificial intelligence technology. Coined in the 2020s, the term has a derogatory connotation akin to "spam".

It has been variously defined as "digital clutter", "filler content produced by AI tools that prioritize speed and quantity over substance and quality", and "shoddy or unwanted AI content in social media, art, books and, increasingly, in search results".

Jonathan Gilmore, Professor of Philosophy at the City University of New York, describes the "incredibly banal, realistic style" of AI slop as being "very easy to process".

🔗 Japan 🔗 Jazz

Jazz kissa (Japanese: ジャズ喫茶), sometimes transliterated as jazu kissa, are cafés that specialise in the playing and appreciation of recorded jazz music. Unique to Japan, jazz kissa are spaces where jazz music is played for dedicated listening rather than as background music. A typical jazz kissa features a high-quality stereo system, a large music collection and dim lighting, and serves coffee and alcoholic drinks.

The first cafés focussed on playing recorded jazz opened in Japan in the late 1920s as part of a wider enthusiasm for Western culture and music. Before World War II there were about 80 jazz kissa, but during the war many of them closed. The post-war period saw jazz kissa return in even greater numbers. Jazz kissa served as places to hear imported jazz records that were too expensive for individuals to buy. They were an important musical resource for musicians, journalists and jazz enthusiasts, and, at their peak, there were around 600 jazz kissa operating across Japan.

Starting in the 1970s, easier and cheaper access to personal stereo equipment and jazz music challenged the role of the jazz kissa. Jazz kissa numbers greatly reduced and the remaining kissa were mainly visited for nostalgic reasons. However, jazz kissa continue to operate in Japan and new kissa are still being opened. Jazz kissa played a role in the reception of jazz music and modern Western culture in Japan. Their influence extends beyond Japan with listening bars inspired by jazz kissa opening in many other countries in the 21st century.
