Whicker: Cubs knock Dodgers’ brooms out of the park Related Articles That has earned a healthy dose of respect from Kershaw.“I can’t imagine coming to a new organization, in the middle of a pennant race and wanting to prove that you’re the pitcher we traded for,” Kershaw said. “And on the cusp of free agency, wanting to showcase your skills and at the same time wanting to tinker with things and change some things to make yourself even better. Yu’s been amazing about that.“He’s been so open with guys, talking to them about stuff. He asks a lot of questions too which I thought was great. Somebody who was a superstar in Japan and has been an ace here, striking out the world for his whole career and to have that openness about asking questions and trying to figure things out – that’s a really cool trait to have for a guy that’s had as much success as he’s had.”TRUE GUTRoberts meets with his coaching staff and members of the front office before every game “and throw crazy scenarios out there … and you kind of go through it and look at their lineup and see every situation that might present itself.”Well, not every situation. Roberts admitted that they never discussed calling back a pinch-hitter and letting the pitcher bat with the bases loaded and two outs in the sixth inning of a two-run game – as Roberts did with Darvish in Game 3 on Tuesday.“We didn’t get to that scenario,” Roberts said with a smile. “That was probably 99 percent gut.”Roberts said he didn’t make the decision until after Joc Pederson had failed to get the runner in from third with less than two outs and pinch-hitter Curtis Granderson was already walking toward home plate.Darvish drew a four-pitch walk to force in a run and got Roberts four more outs on the mound, pitching into the seventh inning.SEAGER PROGRESSInjured shortstop Corey Seager continues to progress in his recovery from a lower back sprain.Roberts said Seager did some straight-line running and played catch as part of his workout in Los Angeles on Wednesday. He is expected to take swings Thursday for the first time since receiving an epidural injection to treat the injury and hit off a tee.Roberts said the progress Seager has made over the past few days has made him more confident that Seager will be able to return and play in the World Series. NLCS Game 5: Dodgers at Cubs, game time, TV info and starting pitchers CHICAGO — When Yu Darvish joined the Dodgers, Clayton Kershaw had a bit of advice for him.Stop thinking so much.“I’m good at telling people to do that,” Kershaw said. “Not think.”Kershaw explained that he had watched Darvish pitch and thought the right-hander was distracting himself with thoughts about things like his mechanics and arm slot during the game. Whicker: What price victory? Cubs dug deep to win Game 4 Cubs deny Dodgers’ bid to sweep their way into World Series LA Metro pokes fun at Chicago’s transit system after Dodgers’ 6-1 victory over the Cubs “I saw him kind of on the mound thinking about a release point and doing this with his arm (moving it around) and trying to feel it,” Kershaw said. “All that stuff was awesome in between starts. But it’s hard enough to get major-league hitters out when you’re not thinking about your mechanics.“All I told him was those four days (between starts) you tinker. You work on whatever you need to do. But that fifth day you’re out there – your stuff is so good, just go compete. Just go get those guys out and we can look back the next day on the mechanical stuff. I don’t know if it’s helped or not. But he’s pitched really well.”The Dodgers have encouraged Darvish to change a number of things since he joined them from Texas – his arm slot, the rhythm of his delivery and his pitch mix.“Yeah – except his beautiful face. Is that what Yu said?” Kershaw joked, referring to Darvish’s answer at a news conference during the NL Division Series.The changes seem to have taken hold and are working. Over his past five starts (including two in the postseason), Darvish has a 0.88 ERA, a 0.68 WHIP, 35 strikeouts and only two walks in 30-2/3 innings.

UPPER MARLBORO, Md. – Two months into the school year, more than 2,000 students in this suburban county outside the nation’s capital had yet to get the shots they needed to attend class. So the school system decided it was through playing nice. Parents in Prince George’s County have been ordered to appear at a special court hearing today where they will be given a choice: Get their children vaccinated on the spot or risk up to 10 days in jail and fines. It is one of the strongest efforts made by a U.S. school system to ensure its youngsters receive their shots. Prince George’s County school officials and prosecutors said parents have been duly warned about the need for vaccinations over the past year. They said the goal isn’t to throw parents in jail but to protect public health and get kids who have been barred from school back to class. 160Want local news?Sign up for the Localist and stay informed Something went wrong.

The energy harvester consists of a carbon fiber beam with a piezoelectric sensor and stepper motor to adjust the angle of attack of the airflow in the wind tunnel. Unlike previous designs, the system does not require a secondary vibrating structure because the beam itself vibrates, reducing the volume of the harvester and increasing its efficiency.

Zakaria, et al. “Experimental analysis of energy harvesting from self-induced flutter of a composite beam.” Applied Physics Letters. DOI: 10.1063/1.4926876 Journal information: Applied Physics Letters © 2015 Phys.org The researchers, Mohamed Y. Zakaria, Mohammad Y. Al-Haik, and Muhammad R. Hajj from the Center for Energy Harvesting Materials and Systems at Virginia Tech, have published a paper on the new energy-harvesting method in a recent issue of Applied Physics Letters.”The greatest significance of the work is the reduction of the volume of the harvester, which translates to an increase in the power density, by eliminating the need for a secondary structure to be attached to the beam,” Zakaria said. “This reduction is important in the design of very small harvesters that can be used to develop self-powered sensors.”The research shows that subjecting a flexible beam to wind at the right angle of attack can cause the beam to bend so much that the beam’s “flutter speed” is significantly reduced. A large degree of bending also induces a change in the beam’s natural frequencies that basically results in a synchronization of the beam’s bending and twisting frequencies. Specifically, the beam’s second bending frequency and torsional frequency coalesce, resulting in “self-induced flutter” of the beam. Complex aerodynamic effects ensure that the vibrations are self-sustaining, allowing for continuous energy harvesting.The researchers demonstrated the design using a flexible cantilever beam with a piezoelectric transducer, which they hung from the ceiling in a wind tunnel. They found that the amount of energy harvested depends on a combination of factors, including the wind speed and the angle at which the wind hits the beam. At a wind speed of 10 m/s and 5.4° angle, the method can harvest approximately 0.3 mW of power. Although the researchers plan to improve the power levels, even this small value can be used to power individual sensors, which, as Zakaria explained, have a wide variety of applications.”Future monitoring of different systems and platforms such as air and water systems, structures, vehicles, infrastructure, etc., as well as secure data transmission and reception from these sensors, will require the use of hundreds or thousands of sensors, data loggers and hardware components,” Zakaria said. “The ability to integrate energy harvesters within these sensors or data loggers to develop such self-powered instruments is very much needed to enable their use without the need to replace batteries on a regular basis.”In the future, the researchers plan to design even smaller beams with specific geometries and capabilities, as well as to improve the performance of the piezoelectric elements.

(Phys.org)—In an attempt to harvest the kinetic energy of airflow, researchers have demonstrated the ability to harvest energy directly from the vibrations of a flexible, piezoelectric beam placed in a wind tunnel. While the general approach to harvesting energy from these “aeroelastic” vibrations is to attach the beam to a secondary vibrating structure, such as a wing section, the new design eliminates the need for the secondary vibrating structure because the beam is designed so that it produces self-induced and self-sustaining vibrations. As a result, the new system can be made very small, which increases its efficiency and makes it more practical for applications, such as self-powered sensors. Explore further

Plasmons are, of course, oscillations of electrons near the surface of a material. They are relevant to solar energy applications because they can be triggered by photons. But how this process works is still under investigation. Prior research has suggested plasmon-excited reactions are due to high-energy electrons that are generated as plasmons decay. But in this new effort, the researchers found that it is possible to impact molecules directly using plasmons.The technique involved using a scanning tunneling microscope to observe a reaction caused by plasmon excitation. They pointed the tip of the microscope’s probe at a single molecule of dimethyl disulfide atop a metal base. The researchers noted that the molecule formed an elliptical protrusion as it sat in a plasmonic field. The team then shone light of different wavelengths on the molecule, which caused changes to the plasmons around it. Those changes, in turn, caused a change in the dimethyl disulfide molecule. It separated into two round protrusions. This, the researchers suggest, occurred because the plasmons had broken the bond holding the components together. They note that their technique is not consistent with the high-energy theory and suggest that the plasmons were actually absorbed by the molecule, which led to weakening the bonds that held it together.The team has plans to test their technique using other molecules to learn more about which sorts of reactions might occur. Their hope is that, unlike with their example, other reactions will not be constrained by special temperature and pressure requirements. Such conditions are assumed to be necessary for use in manufactured applications. A team of researchers from Japan, Korea and the U.S. has found a way to demonstrate an example of plasmons directly causing changes to a molecule. In their paper published in the journal Science, the group describes their technique and what they learned from it. Journal information: Science © 2018 Phys.org More information: Emiko Kazuma et al.

No third child after the birth of two daughters and only Re 1 to be taken from the girl’s family by the groom were among a host of rulings given out by a Khap Panchayat in the town to discourage the practices of female foeticide and dowry.In an announcement that comes as a breath of fresh air as khaps are infamous for issuing orthodox diktats, Bura Khap’s head Rajbir Bura said that members in a meeting held on Sunday had decided to felicitate couples, who do not have a third child after the birth of two daughters and those who took no or only Re 1 as dowry from the bride’s family. Also Read – Punjab on alert after release of excess water from Bhakra damThe Khap has also put a limit on the number of members to be part of the bridegroom’s wedding procession at 21.“The decision was much needed as too many people constituting a ‘baraat’ puts unnecessary financial burden on the bride’s family,” the Khap head said.Bura said a decision to shorten the mourning period after a family member’s death from 13 to 7 days was also taken during the meeting. “It was also decided to end the old practice of not having wheat flour, pulses and ghee (clarified butter) during the mourning period.” Felicitating sportsmen, social activists and writers was also proposed during the meeting.
Siliguri (WB): West Bengal Chief Minister Mamata Banerjee on Thursday demanded that the Centre should slash fuel prices by Rs 10 per litre at least and also withdraw the cess on petroleum products. Banerjee was reacting to the Centre’s announcement of a Rs 2.50-per-litre cut in petrol and diesel prices by reducing the excise duty by Rs 1.50 a litre and asking oil companies to absorb another Re 1. “The central government should slash fuel prices by Rs 10 at least. This government at the Centre is not bothered about the well-being of the masses… They are only interested about their party (BJP),” Banerjee, whose government had last month slashed petrol and diesel prices by Re 1 per litre, said while addressing a programme in Siliguri. The Centre should also withdraw the cess on petroleum products. The increase in fuel prices have a spiralling effect on the prices of essential commodities, the chief minister added.
Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Growing a business sometimes requires thinking outside the box. October 15, 2008 3 min read All those business bits and bytes add up, and finding ways to store them can be a constant challenge. Most entrepreneurs will turn to a combination of storage technologies ranging from USB flash drives to full-on network storage systems. We used to talk about storage mainly in gigabytes (GB), but we’ve now magnified that into terabytes (TB). The onward march of storage technology is turning in bigger storage, more advanced features and lower prices for growing businesses.The Dell PowerVault MD3000i iSCSI SAN is a Storage Area Network (SAN) system with some muscle to handle more sophisticated storage needs while still working with your existing Ethernet network. Dell’s iSCSI solution is a more affordable option than the Fibre Channel systems that have dominated the SAN market. With expandability up to 45TB, it gives a business plenty of room to grow. The $1,400 Netgear ReadyNAS NV+ RND4210 is a 2TB Network-Attached Storage (NAS) solution tucked into a compact appliance. It’s stuffed with user-friendly features like printer sharing, built-in backup, system monitoring and automatic alerts.For a single computer or a very small workgroup backup, the $550 2TB Western Digital My Book Mirror Edition is ready to keep two copies of all your data. The two hard drives can be set to mirror the data using RAID 1 technology to protect your information should one hard drive fail. In a similar vein, the $300 Newer-Tech Guardian MAXimus 500GB has both Firewire and USB connections and two 500GB drives that mirror each other. It’s available in sizes up to 1TB (with two 1TB drives).Portable storage can be just as important as storage at the office. If you take your laptop home to work or for travel, you still need to back up and store the data. The Buffalo Technology MiniStation DataVault features a 320GB hard drive mounted in shock absorbers. It includes automatic backup software and encryption to help safeguard your data on the road. For a huge amount of storage, the Iomega eGo Desktop Hard Drive USB 2.0 is a 1TB external drive that weighs 2.4 pounds. You might not want to carry it around with your laptop, but it can be easily moved between computers. Other hardware storage solution providers to check into include Advanced Vault, Kingston Technology, SanDisk, Other World Computing and To-shiba.Not all storage options hang out in your office. HP Upline Professional is an online storage service for businesses. With unlimited storage, it’s a handy option for businesses with remote and mobile employees. Data can be backed up, managed and shared online. Symantec Online Backup is another option, and it starts at $9.99 per month for 10GB of backup space. The price goes up for the amount of storage and the length of historical data retained. Online services can also act as an extra layer of protection along with an on-site storage solution. Some other online storage options with business-level capabilities include Box.net and Nirvanix. Register Now » This story appears in the November 2008 issue of Entrepreneur. Subscribe »
