 Dr. Faheem Younus, the chief of Infectious Diseases at University of Maryland, Upper Chesapeake Health, debunked some of the myths about coronavirus. #coronavirus #COVID-19 # coronavirusspread

 Now something practical and honest from the : Head of the Infectious Disease Clinic, University of Maryland,

1. We may have to live with C19 for months or years. Let's not deny it or panic. Let's not make our lives useless. Let's learn to live with this fact.

2. You can't destroy C19 viruses that have penetrated cell walls, drinking gallons of hot water - you'll just go to the bathroom more often.

3. Washing hands and maintaining a two-metre physical distance is the best method for your protection.

4. If you don't have a C19 patient at home, there's no need to disinfect the surfaces at your house.

5. Packaged cargo, gas pumps, shopping carts and ATMs do not cause infection.

Wash your hands, live your life as usual.

6. C19 is not a food infection. It is associated with drops of infection like the ‘flu. There is no demonstrated risk that C19 is transmitted by ordering food.

7. You can lose your sense of smell with a lot of allergies and viral infections. This is only a non-specific symptom of C19.

8. Once at home, you don't need to change your clothes urgently and go shower!

Purity is a virtue, paranoia is not!

9. The C19 virus doesn't hang in the air. This is a respiratory droplet infection that requires close contact.

10. The air is clean, you can walk through the gardens (just keeping your physical protection distance), through parks.

11. It is sufficient to use normal soap against C19, not antibacterial soap. This is a virus, not a bacteria.

12. You don't have to worry about your food orders. But you can heat it all up in the microwave, if you wish.

13. The chances of bringing C19 home with your shoes is like being struck by lightning twice in a day. I've been working against viruses for 20 years - drop infections don't spread like that!

14. You can't be protected from the virus by taking vinegar, sugarcane juice and ginger! These are for immunity not a cure.

15. Wearing a mask for long periods interferes with your breathing and oxygen levels. Wear it only in crowds.

16. Wearing gloves is also a bad idea; the virus can accumulate into the glove and be easily transmitted if you touch your face. Better just to wash your hands regularly.

17. Immunity is greatly weakened by always staying in a sterile environment. Even if you eat immunity boosting foods, please go out of your house regularly to any park/beach.

Immunity is increased by EXPOSURE TO PATHOGENS, not by sitting at home and consuming fried/spicy/sugary food and aerated drinks.

Self-Driving Wheelchairs Debut in Hospitals and Airports 

The autonomous vehicles sense positions, select routes, and stop for obstacles

SMART scores another first with Singapore's self-driving wheelchair that has been piloted at a hospital

Autonomous vehicles can add a new member to their ranks—the self-driving wheelchair. This summer, two robotic wheelchairs made headlines: one at a Singaporean hospital and another at a Japanese airport.

The Singapore-MIT Alliance for Research and Technology, or SMART, developed the former, first deployed in Singapore’s Changi General Hospital in September 2016, where it successfully navigated the hospital’s hallways. It is the latest in a string of autonomous vehicles made by SMART, including a golf cart, electric taxi and, most recently, a scooter that zipped more than 100 MIT visitors around on tours in 2016.

The SMART self-driving wheelchair has been in development for about a year and a half, since January 2016, says Daniela Rus, director of MIT’s Computer Science and Artificial Intelligence Laboratory and a principal investigator in the SMART Future Urban Mobility research group. Today, SMART has two wheelchairs in Singapore and two wheelchairs at MIT being tested in a variety of settings, says Rus.

The robot’s computer uses data from three lidars to make a map. A localization algorithm then determines where it is in the map. The chair’s six wheels lend stability, and the chair is designed to make tight turns and fit through normal-sized doorframes. “When we visited several retirement communities, we realized that the quality of life is dependent on mobility. We want to make it really easy for people to move around,” said Rus in a recent MIT statement.

A second autonomous wheelchair recently premiered at Haneda Airport in Tokyo, designed by Panasonic and Whill, Inc., creator of the Model A Whill wheelchair, a sleek, hi-tech wheelchair now on the market in Japan and the United States.

According to a recent press release, Panasonic is planning to conduct technical trials of the WHILL NEXT this year. Like the SMART wheelchair, the WHILL NEXT uses sensors to detect nearby obstacles. It also employs automation technology developed for Panasonic’s autonomous (and adorable) hospital delivery robot, HOSPI. The wheelchair identifies its position, selects routes, and moves to a chosen destination based on a user’s input into a smartphone app. It can even be hailed with the app – the Uber of wheelchairs.

The WHILL NEXT is also able to sync up with nearby wheelchairs to travel in a column, which is useful for a family or a group, the company notes. Best of all, each wheelchair automatically returns to its home base, reducing the need for airport staff to collect the chairs.

Beyond use in hospitals and airports, the SMART team says they envision a connected autonomous mobility system, where a user could use a scooter or wheelchair indoors at an office, zip outside and pick up a golf cart to cross the parking lot, and slip into an autonomous car to drive home. Recent studies with the scooter suggest the control algorithms work indoors as well as out, according to a press release last year. “The autonomous wheelchair could be very useful in any pedestrian environmen—including hospitals and airports —and we are exploring all these possibilities,” Rus tells IEEE Spectrum.

Yet the field faces the challenge of commercialization. Not all hi-tech wheelchairs have sold well, such as Dean Kamen’s stair-climbing iBot, whose $25,000 price tag was one reason the device was discontinued in 2009. But hopefully the next generation of wheelchairs won’t be as expensive, says Rus. “The system consists of an off-the-shelf wheelchair augmented with an autonomy package. We hope the price point of the autonomy package can come down to make the system affordable.”

“A version of this post appears in the October 2017 print issue as “Lidar-Equipped Autonomous Wheelchairs Roll Out in Singapore and Japan.”

what is wifi 6?

— 123rf.com Wifi 6 is better at talking to more devices at once. It is claimed to help everything on your network work better and faster.

WE all know what Wifi is, but not a lot of us know there are different versions of the 802.11 Wifi standard. The versions have been labelled by letters like 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac.

The Wifi Alliance, the group that sets the Wifi standards, has decided to change the naming scheme, and the newest version of Wifi is known simply as Wifi 6, meaning it’s the sixth generation of the Wifi standard.

Those names were pretty clunky before, so I like the new ones.

Going forward, 802.11n is Wifi 4, 802.11ac is Wifi 5 and what was called 802.11ax is simply known as Wifi 6.

Each generation of Wifi has been an improvement over the previous generation – usually by making the download speeds faster.

Wifi 5 had a theoretical top speed of 3.5Gbps (gigabits per second), but real world speeds are always slower depending on the environment and obstacles.

Wifi 6 has a top speed of 9.6Gbps, but more importantly, it introduces some new technologies to make all the devices on your home’s network operate faster, especially if you have a lot of Wifi devices.

Wifi 6 is better at talking to more devices at once. It will help everything on your network work better and faster.

Your device communication will also be more secure with the introduction of a new Wifi security protocol called WPA3.

To take advantage of Wifi 6, the first thing you’ll need is a new router. Most of the advantages of Wifi 6 happen on the router side.

Right now there are not very many Wifi 6 routers for sale. Tp-link and Netgear have a few. Others will certainly follow.

The Wifi Alliance also has an information page on its site, Wifi. org, that describes Wifi 6 in more detail, if you’re interested. — The Dallas Morning News/tribune News Service

A stroke is a medical condition in which poor blood flow to the brain results in cell death.^[5] There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding.^[5] Both result in parts of the brain not functioning properly.^[5] Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side.^[2][3] Signs and symptoms often appear soon after the stroke has occurred.^[3] If symptoms last less than one or two hours it is known as a transient ischemic attack (TIA) or mini-stroke.^[3] A hemorrhagic stroke may also be associated with a severe headache.^[3] The symptoms of a stroke can be permanent.^[5] Long-term complications may include pneumonia or loss of bladder control.^[3]
The main risk factor for stroke is high blood pressure.^[6] Other risk factors include tobacco smoking, obesity, high blood cholesterol, diabetes mellitus, a previous TIA, end-stage kidney disease, and atrial fibrillation.^[2][6][7] An ischemic stroke is typically caused by blockage of a blood vessel, though there are also less common causes.^[12][13][14] A hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes.^[12][15] Bleeding may occur due to a ruptured brain aneurysm.^[12] Diagnosis is typically based on a physical exam and supported by medical imaging such as a CT scan or MRI scan.^[8] A CT scan can rule out bleeding, but may not necessarily rule out ischemia, which early on typically does not show up on a CT scan.^[9] Other tests such as an electrocardiogram (ECG) and blood tests are done to determine risk factors and rule out other possible causes.^[8] Low blood sugar may cause similar symptoms.^[8]
Prevention includes decreasing risk factors, as well as possibly aspirin, statins, surgery to open up the arteries to the brain in those with problematic narrowing, and warfarin in those with atrial fibrillation.^[2] A stroke or TIA often requires emergency care.^[5] An ischemic stroke, if detected within three to four and half hours, may be treatable with a medication that can break down the clot.^[2] Aspirin should be used.^[2] Some hemorrhagic strokes benefit from surgery.^[2] Treatment to try to recover lost function is called stroke rehabilitation and ideally takes place in a stroke unit; however, these are not available in much of the world.^[2]
In 2013 approximately 6.9 million people had an ischemic stroke and 3.4 million people had a hemorrhagic stroke.^[16] In 2015 there were about 42.4 million people who had previously had a stroke and were still alive.^[10] Between 1990 and 2010 the number of strokes which occurred each year decreased by approximately 10% in the developed world and increased by 10% in the developing world.^[17] In 2015, stroke was the second most frequent cause of death after coronary artery disease, accounting for 6.3 million deaths (11% of the total).^[11] About 3.0 million deaths resulted from ischemic stroke while 3.3 million deaths resulted from hemorrhagic stroke.^[11] About half of people who have had a stroke live less than one year.^[2] Overall, two thirds of strokes occurred in those over 65 years old.<sup>[17]
