Cause, effect and the need to test for COVID-19 | Marsha Mercer

A wise editor of mine used to say, “Wet streets don’t cause rain.”

John’s point, of course, was not to confuse cause and effect. I’ve thought about his warning often since President Donald Trump began his counter-narrative about coronavirus testing.

As the number of positive cases of COVID-19 soared this summer, Trump repeatedly blamed the tests for causing the cases.

Testing “makes us look bad,” he tweeted in June.

At the Tulsa rally a few days later, he said, “I said to my people, ‘Slow the testing down, please.’”

His aides tried to pass that remark off as a joke, but Trump said, “I don’t kid.”

“Cases, Cases, Cases! If we didn’t test so much and so successfully, we would have very few cases,” he tweeted in July.

And, he told reporters, “When you test you create cases.”

That’s all wrong. Pregnancy tests don’t create babies.

Two San Antonio medical facilities selected for COVID-19 vaccine trials

Brooke Army Medical Center and Wilford Hall Ambulatory Surgical Center are two of five sites selected by the U.S. Department of Defense for Phase III of COVID-19 vaccine trials.

As part of Operation Warp Speed, which is focused on delivering safe and effective vaccines by January 2021, the DOD has picked five locations to test AstraZeneca’s vaccine candidate, AZD1222.

Otto Aviation Hopes To Torpedo The Business Jet Market With Its Curious New Design. Will It Sink Or Swim?

Otto Aviation is looking for investors to advance its unconventional “Celera” business aircraft from a prototype to a production airplane built in the thousands. The media attention the company has garnered since formally unveiling the Celera 500L last week is no doubt pleasing.

But with the spotlight comes scrutiny and the questions that all startup aviation manufacturers face. The answers often determine whether a new effort even reaches the market. In Otto’s case the mere appearance of the Celera with its bulbous fuselage, pusher propeller and short, thin wing, leads to questions.

The man responsible for the project, and the Celera’s distinctive shape, is William Otto Sr., a former researcher at Los Alamos National Laboratory, chief scientist at North American Aviation (subsumed by Boeing in the 1990s after a series of mergers) and founder of aviation

Trump’s plotting for a pre-election vaccine carries real dangers for your health

The Trump administration is plainly counting on a vaccine for COVID-19 becoming approved by the Nov. 3 election, in the expectation that news of the discovery will inspire a tide of public optimism that will sweep Trump to reelection.

Here’s a more judicious counsel about how you should be reacting to the administration’s push for rapid approval of a vaccine: Be afraid. Be very afraid.

Premature approval of a COVID-19 vaccine will sabotage public confidence in its safety. That in turn will give fuel to the anti-vaccine movement, undermining public health by allowing a resurgence of vaccine-preventable diseases such as measles.

When I hear things like ’emergency use authorization’ I get very worried, because we’ve never done that for a vaccine that’s going to be given to a large segment of the population.

Rivian to test its electric pickup’s ‘adventure’ capability in Rebelle Rally

Rivian is going to test its claim that its R1T electric pickup is adventure-capable in the Rebelle Rally next month.

Ever since coming out of stealth mode with their electric vehicles, Rivian made it clear that they are targeting people who get the most out of their trucks: People who like to go on adventures.

They specifically call their R1T pickup and R1S SUV “electric adventure vehicles.”

Rivian already tested the R1T’s mantel as a support vehicle on The Long Way Up trip in Harley Davidson’s Livewire.

Now they are going to put it to the test in the Rebelle Rally, a 2,000-km (1,243-mile) rally across California and Nevada:

The Rebelle Rally is the longest competitive off-road navigation rally in the United States. The remote rally will take place over 10 days and 2,000 kilometers of stunning roads, dirt roads, trails, dunes, and designated open off-highway vehicle areas across Nevada

More Zegna Than Brooks Brothers

In 1914, brothers Alfieri, Ettore and Ernesto from Bologna, Italy founded a company that bore their family name: Maserati. In 1926, they produce their first original automobile, the Tipo 26. Over the next century, the company produces race cars, sports cars, luxury coupes, sedans and convertibles — some memorable, some forgettable. In 1966, Maserati unveils the Ghibli, a two-door sports car designed by Giugiaro and named for a hot desert wind. The original Ghibli goes out of production in 1973. The nameplate is revived for a two-door coupe in 1992, a car which is built until 1998. In 2013, Ghibli rises again to join the Maserati lineup, this time as a four-door luxury sedan.

Things have changed in the automotive landscape since the last time Ghibli rolled along. Maserati is now part of a large automotive group,

Intel’s DAOS tops the IO500 speed challenge for HPC storage

Intel’s Distributed Application Object Storage (DAOS) object storage system – now open-sourced, but developed to make use of its super-fast Optane storage – came out top this summer in the IO500, which measures high-performance computing (HPC) hardware, software and file system combinations against each other.

DAOS arrived in 2015, and is an object storage system designed around Intel’s 3D Xpoint Optane technology, which provides something approaching the high-speed access capabilities of RAM but with persistent storage.

Intel wants DAOS to be a successor to the Lustre file system, which it previously held rights to but sold to DDN in 2018. In the November 2019 IO500, Lustre came third with a score of 453.68 while DAOS was second with 933.64, just behind winner WekaIO with its Matrix system.

The IO500 test measures throughput and the speed of access to files between a compute node chosen

Artificial intelligence manages congenital cataract with individualized prediction and telehealth computing

Dataset collection and preparation for agent training

The pipeline for our study is shown in Fig. 1. The training dataset included clinical records of 594 CC patients before and after surgery, and 4881 of their follow-up images from January 2011 to December 2016. The eligible criteria of patients included diagnosis of CC, informed consent, and completed records of baseline information, lesion condition, comorbidities, surgical procedures, and complications in the first follow-up year. The eligible images for training were defined as the anterior segment images covering the posterior lens capsule by retro-illumination using slit-lamp photography. All these records were derived from routine examinations at the Childhood Cataract Program of the Chinese Ministry of Health (CCPMOH)18.
