John McEnroe has claimed that Serena Williams, who is the best player of her gender, would be ranked 700 in the men’s circuit.The seven-time major champion, speaking as part of a tour to promote his new book ‘But Seriously’, said that while he has great respect for Serena, he would place the 23-time Grand Slam winner “like 700 in the world” on the men’s circuit.”Best female player ever – no question.””If she had to just play the circuit – the men’s circuit – that would be an entirely different story,” Sport24 quoted McEnroe as saying.McEnroe asserted that that Williams’ mental toughness would be one of the things that she would be having her way on the men’s tour.”The reality of what would happen on a given day is Serena could beat some players, I believe, because she is so incredibly strong mentally,” he said.”She could overcome some situations where players would choke because she’s been in it so many times, so many situations at Wimbledon, The US Open, etc,” he added.The American became the oldest woman to win a grand slam when he won the 2015 Wimbledon title at the age of 33.The 35-year-old tennis star has 23 grand slam singles crowns and 14 doubles titles in majors.Swiss maestro Roger Federer, by comparison, has 18 singles Slams and none in doubles.It should be noted that the ATP Tour Rankings go only to the top 500. At present, Andy Murray is the current top ranked ATP Tour player while Uzbekistan’ Temur Ismailov holds down the 500th spot.advertisement
The Internet of Things (IoT) continues its rapid growth, but in the rush to capitalize on great business opportunities, many companies miss key technical opportunities to gain market share and lock in a large, highly satisfied installed base. Application areas including smart cities, smart agriculture, smart energy, smart environment, smart homes, connected cars, smart buildings, and wireless medical devices are driving forecasts of tens or hundreds of billions of devices over the next few years. Companies that make the right decisions for device operation at end of battery life can delight customers and gain a competitive advantage. Battery life is key Many IoT applications rely on small, non-rechargeable batteries, so optimizing battery life is important for several reasons. The most obvious reason is that customers prefer long operating life; device vendors who demonstrate superiority in this area will have a key competitive advantage that drives market share growth. In some cases, a long battery life may be essential to a project’s economic viability, and early failures of sensors and actuators may lead to unacceptably high replacement costs. If these costs are covered under warranty, the financial risk to the manufacturer may be extremely high.There are also environmental issues associated with batteries, and proper disposal costs both time and money. Furthermore, some devices are installed in locations that are difficult to access, so the labor costs of battery replacement are considerable. If the battery is in an implanted medical device, the cost and risk go up exponentially, to say nothing of the legal and human costs associated with failed medical devices.To understand how products consume battery power, manufacturers use various tools to perform battery drain analysis (BDA). For simple devices that consume power at a steady rate, a digital multimeter (DMM) may suffice. For complex devices, such as cell phones and IoT devices, the current waveforms are highly variable, with fast switching between operational modes in the tens or hundreds of milliamps and sleep modes measured in micro- or nano-amps. To meet this challenge, modern BDA instruments must have good measurement bandwidth and seamless ranging to avoid losing data during measurement range changes. Beyond battery drain analysis to event-based power analysis To make the appropriate design enhancements, design engineers also must know what is causing the charge consumption. This is particularly important for IoT device designers, because the IoT evolves quickly and product development cycles are very tight. Design and validation engineers must get quick insights into how and why their devices consume power, so correlating charge consumption with RF and sub-circuit events is key. Many engineers find that event-based power analysis quickly reveals what events they need to focus on to improve their device’s charge consumption behavior. For example, event-based power analysis software can automatically analyze a waveform to produce fast, graphical insights, as shown below in figure 1. Figure 1: Event-based power analysis on Keysight X8712A IoT device battery life optimization solution In this case, the user can quickly see that the events labeled MCU and DUT Tx are consuming more than 80% of the device’s power (bar chart), and that most of the charge is consumed at rates between 5 and 10 mA (CCDF chart, bottom). Such insights allow the design engineer to make intelligent architectural, hardware configuration, and firmware programming choices. The engineer can also quickly re-test the device to see the effects of the changes.Eventually, of course, the device’s battery will near the end of its charge, and what was once a steady 3.3-V battery (for example) will deliver only 3.2 V, then 3.1 V, and so on until it fails completely, often in a mode that turns out to be surprising. Instead of simply letting the device operate normally until the battery fails, you can give your product a competitive edge by carefully answering the following questions: Where is the critical point? What would customers want you do about it?

Mumbai: After the controversial episode of “Koffee With Karan” featuring cricketers Hardik Pandya and K.L. Rahul, their colleague Ravichandran Ashwin has now shown interest in being a guest on the popular celebrity chat show hosted by filmmaker Karan Johar. On Friday, Ashwin did a #AskAsh session on Instagram where he replied to questions from his fans. During the Q and A session, when a fan asked him if would like to go to “Koffee with Karan”, he said: “Sure”. Pandya and Rahul faced a lot of flak for their comments on women when they opened up on their personal life on the latest season of the chat show, which has had guests such as actors Kareena Kapoor Khan, Deepika Padukone, Akshay Kumar and Priyanka Chopra. Apart from receiving flak on social media, Pandya and Rahul were asked to go home from the three-ODI series against Australia in January after being suspended. Karan later said he felt “very responsible” about the repercussions Pandya and Rahul have faced since they made some misogynistic remarks on his chat show but also said he has no control over answers that come his way. When the filmmaker was asked does he think cricketers are off his list now, he quipped: “I think I am off their list.”
San Francisco: Facebook, busy developing more private and encrypted communication across its apps, has lost two of its top executives — Chief Product Officer Chris Cox and WhatsApp Vice President Chris Daniels, CEO Mark Zuckerberg has announced. Embroiled in data privacy scandals amid the unabated spread of fake news on its platform, Facebook has lately seen several high-profile exits, including Jan Koum and Brian Acton, co-founders of WhatsApp. Also Read – Ensure strict implementation on ban of import of e-cigarettes: revenue to Customs”Cox and I have worked closely together to build our products for more than a decade and I will always appreciate his deep empathy for the people using our services and the uplifting spirit he brings to everything he does,” Zuckerberg said in a blog post late Thursday. In a separate Facebook post, Cox said Facebook is turning a new page in its product direction, focused on an encrypted, interoperable, messaging network. “It’s a product vision attuned to the subject matter of today: a modern communications platform that balances expression, safety, security, and privacy. “This will be a big project and we will need leaders who are excited to see the new direction through,” wrote Cox, who was one of the first 15 engineers Facebook hired 13 years back.
People who smoke marijuana or cannabis weigh less as compared to adults who don’t, a new study suggests. The findings are contrary to the belief that marijuana users who have a serious case of the munchies that will ultimately lead to weight gain. “Over a three-year period, all participants showed a weight increase, but interestingly, those who used marijuana had less of an increase compared to those that never used,” said lead author Omayma Alshaarawy from the Michigan State University. Also Read – An income drop can harm brainFor the study, published in the International Journal of Epidemiology, the research team looked at the Body Mass Index (BMI) of 33,000 participants, aged 18 and older, then compared the numbers. While the actual weight difference among users and non-users was modest, around two pounds for a 5-foot-7-inch participant weighing about 200 pounds at the start of the study, the variance was prevalent among the entire sample size. “An average two-pound difference doesn’t seem like much, but we found it in more than 30,000 people with all different kinds of behaviours and still got this result,” Alshaarawy said. The researcher cautions that marijuana should not be considered a diet aid. “There’s too many health concerns around cannabis that far outweigh the potential positive, yet modest, effects it has on weight gain,” Alshaarawy said. “People shouldn’t consider it as a way to maintain or even lose weight.”
NEW DELHI: Police on Saturday lodged a formal complaint against Gautam Gambhir, BJP’s East Delhi Lok Sabha seat candidate, for allegedly holding a public meeting in Jangpura without prior permission from authorities, officials said.The complaint was lodged after East Delhi Returning Officer K Mahesh asked police to take action against the cricketer-turned politician for allegedly violating rules. “We have initiated action against Gautam Gambhir under sections 28/110 of the Delhi Police Act,” Chinmoy Biswal, Deputy Commissioner of Police (Southeast), said. Also Read – CM urges Delhiites to help accident victimsPolice have registered a “kalandra”, which is a formal complaint lodged by police in a non-cognisable offence under the act which gives special power to the force, another officer said. Gambhir did not seek prior permission to hold a public meeting in Janpura on April 25, officials said. However, Delhi BJP spokesperson Harish Khurana claimed that permission was taken for Gambhir’s event and it continued somewhat longer than the scheduled duration. Also Read – Kejriwal seeks Transport Dept’s views on odd-even exemptionThe party’s legal department will take appropriate steps in the matter, Khurana said. The Bhartiya Janta Party has pitted Gambhir against AAP’s Atishi and senior Congress leader Arvinder Singh Lovely from the East Delhi Lok Sabha constituency. Gambhir is making his electoral debut from the seat and has been under attack from the Aam Aadmi Party (AAP) over allegations that he had double entries in voters list. Reacting to the developments, AAP’s Atishi tweeted, “”First, Discrepancies in nomination papers. Then, Criminal offence of having 2 voter IDs. Now, FIR for illegal rally (sic),” My question to Gautam Gambhir: When you don’t know the rules, why play the game? (sic) she said on Twitter. Gambhir landed in a controversy after AAP leader Atishi on Friday filed a complaint against the former cricketer and BJP candidate Gautam Gambhir for allegedly enrolling as a voter in more than one constituency in violation of the Representation of the People Act (RPA). In a petition filed on Thursday, Atishi has alleged that Gautam Gambhir had provided false information in his nomination papers. Atishi claimed that Gautam Gambhir is a registered voter in Delhi’s Karol Bagh as well as Rajinder Nagar, both of which fall under the Central Delhi parliamentary seat. The court will hear the case on May 1. Gautam Gambhir – a supporter of the BJP government’s policies – was welcomed in the party by senior leader Arun Jaitley last month. The former cricketer is one of the richest candidates in Delhi, with an annual income of over Rs 12 crore. A veteran of 58 Tests and 147 one-day internationals, Gautam Gambhir was a key member of the Indian teams that won the T20 World Cup in 2007 and the One-Day International World Cup in 2011. A vocal ambassador of the party on Twitter, his social media posts with strong comments on contemporary politics and incidents had inspired talk about his diving into politics.
Related: The Lab Back in October, when Draymond Green of the Warriors was asked to assess the Rockets’ offseason efforts to narrow the gap between Houston and Golden State, Green didn’t mince words.“They want [a matchup with us] to be a shootout, which is fine,” he said. “But we’re gonna play some defense. Yeah, we score pretty well. But we’re a damn good defensive team, too.” Green, last season’s defensive player of the year, was clearly implying that the same couldn’t be said for Houston, which ranked in the lower half of the league defensively the past two seasons.Green also seized upon a remark from Rockets coach Mike D’Antoni about neither team being able to stop the other. “I don’t know how serious they take defense with that comment,” he said.But a quarter of the way through the season, that question is no longer up for debate: Houston’s defense is elite, and it could finally make the Rockets balanced enough to challenge Golden State. With an immense focus on the Houston offense — specifically, its addition of nine-time All-Star Chris Paul and its continuing 3-point shot crusade — the team’s vast improvement on defense has flown beneath the radar. Entering Thursday’s game with the red-hot Utah Jazz, Houston’s defense is surrendering just 100.9 points per 100 possessions, fifth-best in the league. That defensive rating is slightly better than the Warriors’ and represents a night-and-day difference from last season, when the Rockets ranked just 18th, allowing 106.4 points per 100 possessions.A handful of things explain why the club’s defense has performed so well after a pair of lackluster defensive seasons. Among them: The Rockets have gotten much better at protecting the rim and other high-value spots on the court that once troubled them; the team’s weakest defenders are performing better (or getting luckier?) than they did in the past; and Houston has used its own scoring ability to pay dividends on the other end.Of course many of these improvements, if not all of them, stem from the same thing: the club’s getting solid, versatile defenders during the offseason. Paul’s track record on that end is well chronicled — he’s a perennial leader in steals. But because he was replacing fellow all-defensive first-team member Patrick Beverley, other pickups have had even greater opportunities to take the unit to new heights.Wing players PJ Tucker and Luc Mbah a Moute have been game changers for this defense, giving the Rockets — who already had one of the league’s very best perimeter defenders in an overburdened Trevor Ariza — the ability to switch assignments on the fly when teams set screens against them. They communicate well and don’t get lost backdoor (an area the Rockets struggled mightily with last season). And because both players are tall and strong enough to defend three different positions, Houston can use extremely quick smallball lineups with them, Paul and MVP candidate James Harden, who for years was criticized for his inattentive defense.To get a sense of how just valuable Tucker and Mbah a Moute have been as primary and help defenders, consider this: The Rockets are allowing just 94.1 points per 100 possessions with that duo on the floor this season, third-best in the NBA among two-man lineups that have shared at least 300 minutes together thus far. (Only Boston’s Terry Rozier and Marcus Smart and OKC’s Paul George and Andre Roberson have been better.) At times, Houston almost looks as though it’s playing a zone — with each defender responsible for a man and a half — because of how synchronized the defense is with Tucker and Mbah a Moute. Watch here, as the Nets struggle to get anywhere near the lane because of how every ballhandler sees two Rockets ready to make a play on the ball.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2017/12/almostzone.mp400:0000:0000:26Use Up/Down Arrow keys to increase or decrease volume.Even when only one of them is in the game, reigning Sixth Man of the Year Eric Gordon, who has been fantastic this season on both ends, is another option aside from Ariza. And because of the trust that Tucker and Mbah a Moute have helped establish, Clint Capela and Nene, the team’s bigs, have felt comfortable wandering farther out on the perimeter to meet opposing ballhandlers. That was often a big mistake last season, when the Rockets ranked dead last in rim protection and allowed opponents to shoot 67 percent from inside the restricted area. (This season, Houston has leaped into the top half of the league on that defensive metric.)With smarter, more switchable defenders on the floor, the Rockets have also taken away many of the corner 3-point opportunities that were there for opponents in years past. And so far this season, Houston ranks among the NBA’s top 10 in limiting those attempts. That’s a big shift from last year, when the Rockets were among the 10 worst teams at stifling 3-point attempts from the corner, and the year before, when Houston’s opponents took a greater share of their 3-point attempts from the corner than any other team’s.Perhaps the biggest shift that has taken place this season: Out of nowhere, Houston has become the NBA’s best defensive-rebounding club, nabbing 81.4 percent of opponent’s misses. Limiting second chances is key for the Rockets, who ranked 21st last year and were last in 2015-16, Dwight Howard’s final season with the team.None of this is to say that the Rockets aren’t capable of backsliding on defense. One area they haven’t gotten better in, transition defense, is something an uptempo team like the Warriors could exploit. (We illustrated last season that Harden — despite his ridiculous passing ability — often gets back on defense slowly after a turnover or what he perceives to be a missed call.) And even though the Rockets have had no issues getting stops in half-court situations, there are indications that they’ve been the beneficiaries of good fortune at times. Only three teams (Cleveland, Orlando and New York) are surrendering higher-quality shots than Houston, according to data from Second Spectrum.Some of those looks have stemmed from opponents getting wide-eyed when they see an opportunity to go 1-on-1 against Harden or the slow-footed Ryan Anderson,1Anderson does look far better defensively than he has in years past, in part because of some weight he dropped during the offseason. who has been isolated more than anyone this season outside of the Lakers’ Julius Randle. Both players have held their own — especially Harden, who’s allowing one of the lowest scoring rates among guards2Who defend at least one isolation play per game and have played in at least 15 games. on those plays, according to data from Synergy Sports Technology. But it’s unclear whether that would hold up for an entire season (Anderson’s case is worth watching, because teams are challenging him 2.5 times a game).If anything, though, there’s reason to suspect that the Rockets could get even better on defense before the season concludes. Much has been made of the Harden-Paul duo, which has yet to fully jell because of Paul’s early-season injury. But if those two figure out how to play off each other and make an already impeccable offense even better, it will pay enormous dividends on the other side of the ball.Houston is sloppy with the ball and bad in transition defense, but they lead the NBA in defensive efficiency after a made basket this season, allowing just 95 points per 100 possessions, according to Inpredictable.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2017/12/fullgameposs.mp400:0000:0000:23Use Up/Down Arrow keys to increase or decrease volume.So, when it’s Rockets vs. Warriors, we aren’t going to see a 1990s-style Eastern Conference slugfest, in which the first team to 90 points wins, break out anytime soon. These teams shoot too well for that to happen. But it’s time to stop wondering whether Houston has the defensive horses to be mentioned in the same sentence with Golden State — this Rockets team is different. This Might Be James Harden’s Year
Manchester United manager Jose Mourinho insists young midfielder Andreas Pereira has the mental strength to fight for a role at the club.The midfielder has spent the last two years on loan in Spain with Valencia and Granada but looked very impressive during United’s preseason this summer.Mourinho thinks playing in Spain for two years as a loanee for Granada and Valencia has helped“I wasn’t happy that he didn’t play in his best position for Valencia,” he said, according to Daily Mail.“But from a human point of view, I think it was a great experience. He became more of a man, more ready physically and mentally.”Vidic: “Ronaldo is the most professional footballer I’ve seen” Andrew Smyth – September 14, 2019 Nemanja Vidic opened up on how a 21-year-old Cristiano Ronaldo’s professionalism left him stunned at Manchester United.“Then it was the question in the Premier League to play him in the position we think is the best, to educate him, to help him understand the position.”“The fact that we had only three midfield players for the pre-season, he had to play all the five matches for 90 minutes which was very good for him.”Mourinho took off the player after 45 minutes against Brighton last weekend with United 3-1 down but Pereira could get another chance against Tottenham on Monday night at Old Trafford.
Liverpool manager Jurgen Klopp praised Mohamed Salah after the Egypt international took his Premier League goal to 50 in a 4-3 win over Crystal Palace.Salah’s brace made it 50 in 72 matches – the same as former Reds favourite Fernando Torres, an out-and-out striker – and a record only bettered by Ruud Van Nistelrooy, Andrew Cole and Alan Shearer.And German gaffer Klopp could only sing his praises after enduring a tense ending at Anfield.“Exceptional achievement from a world-class player,” said Klopp via Belfast Telegraph.“Wow, an outstanding number. I heard the names of the other players who got there a bit quicker – Alan Shearer, Ruud Van Nistelrooy, Andy Cole – good strikers as well eh?“Maybe he would have scored more and earlier if I hadn’t played him on the right wing so often.
