The demonstration of hydrodynamic cloaking and shielding at the microscale

Researchers at Technion—Israel Institute of Technology, Technische Universität Darmstadt, and IBM Research Europe have recently proposed a new strategy to simultaneously achieve microscale hydrodynamic cloaking and shielding. While the idea of cloaking or shielding objects has been around for some time now, in contrast with other previously developed methods the technique they proposed allows physicists to dynamically switch between these two states.

“When we started with our research, we were aware of work in this direction that is based on porous metamaterials,” Steffen Hardt, who led the research team at TU Darmstadt, told Phys.org. “Our idea was that you do not need such metamaterials if you can inject momentum in a region around the object to be cloaked/shielded. Effectively, this means that you superpose the external flow field by some tailor-made local flow field. As a result, the total flow field (external and local one) comes out such that cloaking or shielding is achieved.”

As part of their previous studies, the researchers developed methods to locally inject momentum using what is known as electroosmotic flow (i.e., motion of liquids typically induced by an applied voltage across a porous material or other fluid conduits). The key objective of their new study was to demonstrate a new method to cloak/shield objects in a fluid flow and make this functionality real-time adaptive, as previously proposed approaches based on metamaterials are not.

Biden Is Cracking Down On Guns Again With AR-15 Pistol Ban, And He’s Using Heller To Do It

On June 10, the Department of Justice (DOJ) posted, in the Federal Register, a notice of proposed rulemaking and request for public comment, concerning firearms such as AR-15 pistols equipped with “stabilizing braces.” To bolster its position, the DOJ cited the Supreme Court’s decision in District of Columbia v. Heller (2008).

Before explaining how Heller comes to bear in this instance, some background is in order. Stabilizing braces were developed in 2013 to help wounded former military servicemen and other disabled Americans use, one-handed, AR-15s and similar firearms equipped with a barrel under 16 inches in length to reduce weight. But there’s a rub.

The National Firearms Act of 1934 (NFA) doesn’t define “pistol” or “handgun,” but it defines “rifle” as a firearm that, among other things, is “intended to be fired from the shoulder.” Furthermore, it requires federal registration and a $200 tax for any “rifle” less than 26 inches in overall length or having a barrel less than 16 inches in length, commonly referred to as a “short-barreled rifle” (SBR).

Because AR-15s and similar firearms are usually rifles, with shoulder stocks so they may be “fired from the shoulder,” the question has been whether such a firearm, having never been assembled as a rifle, but instead having been assembled from the outset as a pistol using a stabilizing brace instead of a stock, and a barrel shorter than 16 inches, would be considered a handgun or an SBR.

In 2014, the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) issued a letter to a manufacturer of stabilizing braces, stating, “[W]e have determined that firing a pistol from the shoulder would not cause the pistol to be reclassified as an SBR … Generally speaking, we do not classify weapons based on how an individual uses a weapon.”

In 2015, the agency issued a seemingly contradictory letter, stating that “the pistol stabilizing brace was neither ‘designed’ nor ‘intended’ to be used as a shoulder stock, and therefore use as a shoulder stock constitutes a ‘redesign’ of the device,” implying that a firearm so configured might be subject to the NFA. In 2017, the BATFE issued a private letter to a brace manufacturer saying the 2015 letter had been incorrect.

NSA Reveals in FOIA Response that the FBI Involved in “Improper Surveillance” of 16,000 Americans

Then on January 6, after one million Trump supporters rallied with President Trump at the Ellipse outside the White House, some 900 individuals went inside the US Capitol. Over 400 have since been arrested, including those who were waved into the US Capitol by the police standing at the exits.

Since January, the Deep State and Democrats will not release videotapes to Republican lawmakers from January 6th inside or outside the US Capitol.

Earlier this week Revolver News published an important piece on the “unindicted co-conspirators” in the Jan. 6 attack who were never charged by the DOJ or FBI for their part in the violence on Jan. 6.

The “unindicted co-conspirators” were frequently the most violent and leaders of the assault on the US Capitol. They are also likely FBI informants.

Racist Chicago Mayor Lori Lightfoot Declares Racism a “Public Health Emergency” – Diverts $10 Million in Covid Funds to Address Problem

Racist Chicago Mayor Lori Lightfoot on Thursday declared racism a public health emergency and diverted $10 million in Covid funds to address the problem.

Recall, Lightfoot recently was sued last month by Judicial Watch on behalf of The Daily Caller after she denied reporter Thomas Catenacci an interview because he was white.

Lightfoot announced her racist policy last month. She proudly declared she will openly discriminate against white reporters to only allow “black and brown” reporters interviews.

She later defended her policy.

Amazon Deletes America’s Frontline Doctor’s Website from the Internet – Doctors Scramble to Salvage Site

Amerca’s Frontline Doctors, the courageous group of doctors who spoke out against the government’s irresponsible and damaging COVID responses, had their website taken down by Amazon.

The AFLDS reported:

America’s Frontline Doctors website was deleted from the Internet by Amazon.

If you didn’t know, many top websites and services, such as Netflix, Facebook, LinkedIn, and Twitter, and thousands of others, are hosted on Amazon’s Internet servers.

So it came as a surprise when AFLDS received notice from Amazon that they were deleting our website–and that they were giving us less than 4 days to get it off of their server before deleting it from the Internet forever.

Wuhan Lab Found All Genes To Recreate ‘Epidemic Strain’ Of Coronavirus In 2017.

The Wuhan Institute of Virology – increasingly believed to be the source for the SARS CoV-2 coronavirus – obtained “all the genes to make a SARS coronavirus similar to the epidemic strain,” according to a 2017 report by Science News.

The article – “Bats in China carry all the ingredients to make a new SARS virus” – documents how a Wuhan Institute of Virology research team led by the Fauci-funded “bat lady” Shi Zhengli sampled wild bats.

Also cross-posted to the Wuhan lab’s website, the November 30th 2017 report reveals how data collected by Shi’s team enabled the lab to “make a SARS coronavirus similar to the epidemic strain”:

“After five years of surveying bats in a cave in southern China’s Yunnan Province, Zhengli Shi and colleagues discovered 11 new strains of SARS-related viruses in horseshoe bats (especially in Rhinolophus sinicus). Within the strains, the researchers found all the genes to make a SARS coronavirus similar to the epidemic strain, says Shi, a virologist at the Wuhan Institute of Virology, Chinese Academy of Sciences.

These new strains are more similar to the human version of SARS than were previously identified bat viruses, says Matthew Frieman, a virologist at the University of Maryland in Baltimore.

The article, which was recently wiped from the Wuhan Institute of Virology’s website, also notes that Shi and her colleagues found that “several of the strains” could grow in human cells.

LinkedIn censors Swedish journalist’s profile in China after he references Tiananmen Square thesis

Microsoft-owned LinkedIn has censored the profile of Swedish journalist Jojje Olsson in China after he included a single sentence in the “Education” section of his profile that referenced his thesis on the Tiananmen Square massacre and the Cultural Revolution.

LinkedIn is one of the few Western social networks to not be blocked in China because of its willingness to “implement the Chinese government’s restrictions on content” and apply these restrictions to the profiles of non-Chinese users when they’re viewed from China.

By introducing this censored version of LinkedIn in China, the US platform has grown its Chinese user base to 53 million users and China is now its third-largest market.

LinkedIn didn’t specifically mention which part of the Education section in Olsson’s profile had led to the censorship but the sentence on the Tiananmen Square massacre and the Cultural Revolution is the only part of this section that references topics that are often censored by the Chinese state.
