(CNN) -- The stars of tennis took time out from their French Open preparations Sunday to honor the man who helped them become some of the highest-paid athletes in the world.

Brad Drewett passed away Friday, aged 54, succumbing to the motor neurone disease that had forced him to step down as head of the men's ATP World Tour.

Novak Djokovic, Roger Federer, Rafael Nadal, Andy Murray and Serena Williams led a minute's silence ahead of the start of the Madrid Masters, while similar tributes were held at tournaments in Portugal and Germany.

"Brad wasn't just the president of the ATP but was a player himself, a board member," Federer said on the ATP website.

"He's given so much time and effort to the ATP, and I think this is really what we will try to honor in a small way today."

Drewett reached a career-high 34 in the world rankings, but his efforts in administration had far bigger impact on the game, from his time on the players' council to running the ATP's Middle East, Asia and Pacific operations before becoming president in early 2012.

The Australian took the end-of-season championship to China as part of tennis' global spread in the early 2000s, and then brought it to London where it has become a lucrative moneyspinner and showpiece for the ATP.

He has also been credited with getting the players a larger share of prize money from the four grand slam tournaments since he took over the top role a year and half ago.

Last month we reported about a study that showed eating even a little less salt could greatly help the heart. The study was published in the New England Journal of Medicine. The scientists used a computer model to predict how just three grams less salt a day would affect heart disease in the United States.

The scientists said the results would be thirteen percent fewer heart attacks, eight percent fewer strokes , four percent fewer deaths and eleven percent fewer new cases of heart disease And two hundred forty billion dollars in health care savings. Researchers said it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year.

They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt. Such campaigns are already in place in Britain, Japan and Finland.

Michael Alderman is among the critics. He is a high blood pressure expert and professor at Albert Einstein College of Medicine in New York. Doctor Alderman says that eating less salt results in lower blood pressure. But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes. And he says salt has other biological effects. He says calling for reduction in the national diet could have good effects, but it could also have harmful results. He says there is not enough evidence _ .

Another critic is David McCarron, a nutrition and kidney disease expert at the University of California, Davis. He and his team looked at large studies of diets in thirty-three countries. They found that most people around the world eat about the same amount of salt. Most of them eat more salt than American health officials advise. Doctor McCarron says the worldwide similarity suggests that a person's brain might decide how much salt to eat.

Both Doctor McCarron and Doctor Alderman have connections to the Salt Institute, a trade group for the salt industry. Doctor Alderman is a member of an advisory committee. But he says he receives no money from the group. Doctor McCarron is paid for offering advice to the Salt Institute.

arXiv (pronounced "archive") is a repository of electronic preprints, known as e-prints, of scientific papers in the fields of mathematics, physics, astronomy, computer science, quantitative biology, statistics, and quantitative finance, which can be accessed online. In many fields of mathematics and physics, almost all scientific papers are self-archived on the arXiv repository. Begun on August 14, 1991, arXiv.org passed the half-million article milestone on October 3, 2008, and hit a million by the end of 2014. By 2014 the submission rate had grown to more than 8,000 per month.

The arXiv was made possible by the low-bandwidth TeX file format, which allowed scientific papers to be easily transmitted over the Internet and rendered client-side. Around 1990, Joanne Cohn began emailing physics preprints to colleagues as TeX files, but the number of papers being sent soon filled mailboxes to capacity. Paul Ginsparg recognized the need for central storage, and in August 1991 he created a central repository mailbox stored at the Los Alamos National Laboratory which could be accessed from any computer. Additional modes of access were soon added: FTP in 1991, Gopher in 1992, and the World Wide Web in 1993. The term e-print was quickly adopted to describe the articles.
