Patriots’ Tom Brady entering uncharted territory at age 42

ESPN NFL, Mike Reiss from

New England Patriots quarterback Tom Brady turns 42 on Saturday, which is a decisive threshold for him to make another major breakthrough.

No 42-year-old position player has ever started all 16 games in an NFL season.

Furthermore, there are only seven non-specialists who have started a game after their 42nd birthday.

 

Bengals linebacker returns from knee injury

Dayton Daily News, Laurel Pfahler from

… [Carl Lawson] wants to leave no doubt about his impact on the field in Year 3 and doesn’t expect any lingering effects of the ACL tear.

“I feel stronger and faster,” Lawson said. “Just taking it one day at a time and not trying to overwork me. When I got hurt I never thought it was going to take anything special to get back to where I was. The goal was to be better than I was before and that’s the goal coming back from any injury.”

“I had goals last year, but now the goal now is to control what I can control and be healthy and everything else will fall into place,” Lawson added. “I don’t take ability and everything else in production, if you start worrying about that, your game falls off.”

 

Robin Lehner: Out of the darkness and into the light

The Hockey News, Ken Campbell from

Robin Lehner faced his inner demons and shared his struggle with the hockey world, helping to lessen the stigma associated with mental illness and addiction issues.

 

How Tennessee star Thompson went from athlete to ‘proud’ DB

Knoxville News Sentinel, GoVols247, Patrick Brown from

… [Bryce Thompson] credited head coach Jeremy Pruitt, who has a strong reputation in developing quality defensive backs, for helping him make the transition to defense.

“Coach Pruitt is amazing, he focuses on the technique and technique only,” Thompson said. “He makes sure you do that, and everything else is pretty good. He just makes it simple for you, so I don’t really got to use too many little cheats because he makes it so simple for you.”

While Thompson acknowledged his background on offense helped him understand the nuances of playing defense, he said it was Pruitt who taught him the basics of the position, from footwork techniques like kick-slides and how to become effective in press coverage and jamming wide receivers at the line of scrimmage.

 

How departing Osian Roberts transformed football in Wales

Training Ground Guru, Simon Austin from

… “Osian has been a incredible coach educator and strategic leader,” [David] Adams tells TGG. “He has transformed Welsh football in the last 12 years.”

Adams, who leads the Pro Licence course for the Welsh FA, says Roberts has had two major areas of impact – coach education and player development. In terms of coach education, a plethora of top practitioners have earned their badges on FAW courses, including Steve Cooper, Mikel Arteta, Patrick Vieira, Garry Monk, Chris Wilder and Eric Ramsay.

“It’s no coincidence that so many top names want to do the FAW courses,” Adams says. “When Osian came in, the courses were run from Aberystwyth University and he moved them to Dragon Park in Cardiff, where there were better facilities and he was able to create a better learning environment.

 

Klopp: Prem start date ‘doesn’t make sense’

ESPN FC from

“I don’t know why we start that early,” said Klopp, whose side could win the Community Shield, UEFA Super Cup, Club World Cup, Champions League, Premier League, FA Cup and Carabao Cup this season.

Klopp also highlighted the workload of his players after a FIFPro report said the health of some top players is “at risk” and recommended “mandatory offseason breaks of four weeks.”

This summer several Liverpool players have competed in international competitions with Sadio Mane part of the Senegal squad that finished runners-up in the Africa Cup of Nations on July 19 and Alisson winning the Copa America with Brazil on July 7.

 

PRE-SEASON. GETTING READY TO SHAPE THE PHYSICAL FITNESS OF PLAYERS

Barca Innovation Hub from

The objective of the pre-season is to seek the best individual and collective physical fitness of the team before beginning the competition. However, while we have many indicators and information to detect the former, we know much less about the latter. Many years ago, Paco Seirul·lo explained that there are four types of physical fitness in team sports: individual physical fitness, collective physical fitness, physical fitness depending on the opponent, and physical fitness depending on which phase of the season players and teams find themselves.

A recent study has made great advances to uncover more about collective physical fitness.

 

Humans aren’t designed to be happy – so stop trying

The Conversation, Rafael Euba from

… Humans are not designed to be happy, or even content. Instead, we are designed primarily to survive and reproduce, like every other creature in the natural world. A state of contentment is discouraged by nature because it would lower our guard against possible threats to our survival.

The fact that evolution has prioritised the development of a big frontal lobe in our brain (which gives us excellent executive and analytical abilities) over a natural ability to be happy, tells us a lot about nature’s priorities. Different geographical locations and circuits in the brain are each associated with certain neurological and intellectual functions, but happiness, being a mere construct with no neurological basis, cannot be found in the brain tissue.

In fact, experts in this field argue that nature’s failure to weed out depression in the evolutionary process (despite the obvious disadvantages in terms of survival and reproduction) is due precisely to the fact that depression as an adaptation plays a useful role in times of adversity, by helping the depressed individual disengage from risky and hopeless situations in which he or she cannot win. Depressive ruminations can also have a problem solving function during difficult times.

 

Flexible battery works when stretched and could power wearable devices

New Scientist, Donna Lu from

Wearable devices could soon be more flexible – in future they might be powered by stretchable batteries.

Nicholas Kotov at the University of Michigan and his colleagues have developed a conducting component for a lithium-ion battery that maintains its electrical conductivity even when stretched to a strain of more than 300 per cent.

The conductor is made from multiple layers of polyurethane and gold nanoparticles. Polyurethane is a polymer used to make common objects such as foam sponges and garden hoses.

 

Youngstown native shares how he uses artificial intelligence to help train athletes

WKBN (Youngstown, OH), Jennifer Rodriguez from

As technology continues to grow, society finds new ways to advance and prosper. One man from the Valley is using his company to do just that.

Dr. Wayne Mackey started his company State Space just over two years ago.

He uses artificial technology as a way of testing cognitive skills and abilities.

“We’re basically right now, a data artificial intelligence company disguised as a fun gaming company,” Mackey said. “Using AI and my neuroscience background, created a series of tests in fun games that you can do that measure fundamental components of cognitive perceptual motor abilities.”

 

High-tech compression shorts maker Strive aims to measure the ‘miles per gallon’ of athletes

GeekWire, James Thorne from

As a professional basketball player in Montenegro, Nikola Mrvaljevic got the idea that there must be a better way for athletes to train. “Not everybody trains efficiently. We tend to get tired and most of the time we don’t know why,” Mrvaljevic said.

So he started Strive, a wearable technology startup that seeks to answer how and why athletes fatigue. The Bothell, Wash.-based company aims to quantify the “miles per gallon” for a given athlete.

After hanging up his basketball jersey, Mrvaljevic went on to study biomedical and electrical engineering at the University of Rhode Island. He later got an MBA from the University of Washington before co-founding Strive with Carsten Winsnes, a former NCAA crew athlete who is now the company’s COO.

 

Unsupervised 3D Pose Estimation with Geometric Self-Supervision

arXiv, Computer Science > Computer Vision and Pattern Recognition; Ching-Hang Chen, Ambrish Tyagi, Amit Agrawal, Dylan Drover, Rohith MV, Stefan Stojanov, James M. Rehg from

We present an unsupervised learning approach to recover 3D human pose from 2D skeletal joints extracted from a single image. Our method does not require any multi-view image data, 3D skeletons, correspondences between 2D-3D points, or use previously learned 3D priors during training. A lifting network accepts 2D landmarks as inputs and generates a corresponding 3D skeleton estimate. During training, the recovered 3D skeleton is reprojected on random camera viewpoints to generate new “synthetic” 2D poses. By lifting the synthetic 2D poses back to 3D and re-projecting them in the original camera view, we can define self-consistency loss both in 3D and in 2D. The training can thus be self supervised by exploiting the geometric self-consistency of the lift-reproject-lift process. We show that self-consistency alone is not sufficient to generate realistic skeletons, however adding a 2D pose discriminator enables the lifter to output valid 3D poses. Additionally, to learn from 2D poses “in the wild”, we train an unsupervised 2D domain adapter network to allow for an expansion of 2D data. This improves results and demonstrates the usefulness of 2D pose data for unsupervised 3D lifting. Results on Human3.6M dataset for 3D human pose estimation demonstrate that our approach improves upon the previous unsupervised methods by 30% and outperforms many weakly supervised approaches that explicitly use 3D data.

 

Engineers use heat-free tech for flexible electronics; print metal traces on flowers, gelatin

Iowa State University, News Service from

… The technology features liquid metal (in this case Field’s metal, an alloy of bismuth, indium and tin) trapped below its melting point in polished, oxide shells, creating particles about 10 millionths of a meter across.

When the shells are broken – with mechanical pressure or chemical dissolving – the metal inside flows and solidifies, creating a heat-free weld or, in this case, printing conductive, metallic lines and traces on all kinds of materials, everything from a concrete wall to a leaf.

That could have all kinds of applications, including sensors to measure the structural integrity of a building or the growth of crops. The technology was also tested in paper-based remote controls that read changes in electrical currents when the paper is curved. Engineers also tested the technology by making electrical contacts for solar cells and by screen printing conductive lines on gelatin, a model for soft biological tissues, including the brain.

 

Inflammation’s Hidden Role in Weight Loss

The Atlantic, James Hamblin from

Inflammation plays a critical role in determining how we digest food, and it’s only now starting to reveal itself.

 

Injuries so far spoiling Bills’ grand offensive line plans

The Buffalo News, Vic Carucci from

The Buffalo Bills pretty much devoted the offseason and a sizable chunk of cash to trying to improve their offensive line.

It was sound, sensible strategy given the unit’s horrific showing last year. New center. New guards. New tackles. A facelift of mammoth proportions that figured to result in a minimum of four new starters.

At the moment, though, the plan has a lot in common with a smoldering pile of rubble.
