Liverpool manager Jurgen Klopp can’t understand what prompted his Egypt counterpart Javier Aguirre to hand Mohamed Salah transfer adviceThe Mexican coach advised his star forward to consider leaving Liverpool within the next season or two if they fail to win any major trophy.Since his arrival in 2017 from AS Roma, Salah is yet to win any silverware at Anfield with Liverpool beaten in last season’s Champions League final.The Reds also suffered early Carabao and FA Cup exits with a fourth-place finish in the Premier League.But Klopp was left bemused by Aguirre’s advice and even jokingly suggested that he may need to leave Egypt if he can’t win a trophy in the next two years.“Who is the manager? Aguirre? Okay. I’ll try to be nice, eh?” said Klopp, according to the Evening Standard.Report: Origi cause Klopp injury concerns George Patchias – September 14, 2019 Divock Origi injury in today’s game against Newcastle is a cause for concern for Jurgen Klopp.Perhaps with one eye on Tuesday’s trip to Italy…“I would say if HE doesn’t win a title in the next couple of years then he has to move to another club or country, for sure. I don’t know why people say things like that. It’s not that important.“It’s the world of media, you find it somewhere in an Egyptian newspaper or somewhere. Then the next one writes that I was confronted with it.“Obviously I don’t agree with it, but it’s a free world and he can say whatever he wants. That’s good actually.“I shouldn’t have made any comment on it, so maybe we can delete what I said a minute ago!”Liverpool will face Watford away on Saturday in the Premier League.

Manuel Carrillo III/Roadshow One of the fringe benefits of having an electric car is that for the most part, they require much less maintenance than a comparable vehicle powered by an internal combustion engine. Tesla is taking advantage of this after crunching the data on the last few years of service and vehicle data by moving away from a recommended yearly service program to one that only requires vehicles to come in when parts need to be replaced.This probably sounds crazy if you’ve never spent a significant amount of time with an electric vehicle, but think about it like this: What are the most common service items on your ICE-powered car? Oil changes, brakes and tires. Add in things like accessory belts and timing belts that degrade with use and heat and all of a sudden you have a pretty full maintenance schedule.An EV doesn’t have engine oil to change, nor do the motors produce the same kind of heat that gasoline or diesel-powered engines do. Parts aren’t subjected to the same kind of temperature extremes. With brakes, many EV drivers use their vehicles with high levels of regenerative braking. This uses the drivetrain to slow the car and recharge the battery and saves significant wear on the vehicle’s braking components. Brake fluid, however, will still be checked every two years for water contamination.Add in the fact that Teslas are internet-connected and have robust remote diagnostic capabilities and a yearly check-up seems even less necessary. Tesla representatives are quick to point out that this shift in service methodology has nothing to do with a Tesla’s warranty, and vehicles that need service can get it.Tesla will stop pushing its prepaid maintenance plans for customers, but will still honor the plans that have been sold. It seems likely that the “as-necessary” service system will end up being cheaper than a prepaid plan for customers anyway.

Cesar Monzon of Enig Associates, Inc., in Bethesda, Maryland, has presented this new technique in a recent issue of Physical Review Letters. As Monzon explains, many (but not all) subwavelength imaging mechanisms involve a complicated implementation and offer narrowband operation, such as lenses using metamaterials. He hopes that his technique could overcome these challenges with purely resistive means, simply by using a thin electrically conducting sheet to counteract the effects of space’s filtration properties. “An important advantage of the present method is that the resolution of the image so produced is not limited by the extent of a wavelength as in a common lens, but by the separation from the image to the conducting thin sheet,” Monzon told PhysOrg.com. “In fact, the analysis presented in the paper indicates that we can easily form images 10 times sharper than a conventional lens (or 5% of a wavelength of operation). Actually, depending on the frequency of operation, achieving images that are over 20 times higher resolution than possible with diffraction limited optics seems feasible. Hence the proposed technique is that of a ‘superlens,’ because it beats the diffraction limit.”Basically, space acts like a low pass filter for highly evanescent components, and makes evanescent waves very short-lived; these waves usually decay exponentially with the distance from their light source. Monzon found that, when he placed a thin sheet of conducting material close to the light source, the sheet could restore the evanescent components of the light that had been diminished by the air in between. “Saving” these evanescent wave components results in near-field subwavelength imaging right behind the resistive sheet. The “spot size” (imaging area) depends on the separation between the light source and the sheet, meaning that extremely high resolution is possible for very small separations. As an additional benefit, the effect is found to be broadband.”An evanescent wave is essentially a near field wave component that is not propagating away from a radiator, but remains standing in its neighborhood,” Monzon explained. “Evanescent fields are responsible for the reactive energy around a radiator, and generally decay quickly with distance. Just like radiating waves, evanescent waves are a general property of wave equations, and since they basically form the near field of a radiator, they are needed for its proper reconstruction (via focusing or imaging). Now suppose we have a point radiator; if evanescent waves are not used in the reconstruction, such as done by a typical lens (which operate in the far field), then we get a diffraction limited image where the minimum spot size is commensurate with the wavelength. If on the other hand we utilize the evanescent fields, as done here, then we are not bound by a diffraction limited spot size, as the evanescent field spectrum has the ability to form the very near field. For a point radiator this means, in principle, extreme resolution, with a minimum spot size clearly a very small fraction of the wavelength, hence enabling very high resolution imaging.” (PhysOrg.com) — Since the first demonstrations of subwavelength imaging just a few years ago, scientists have been making great improvements, developing a variety of new methods for realizing high-resolution imaging. Recently, a new superlens for subwavelength imaging has been developed that offers a simplified and wide broadband operation. The superlens could potentially shrink the size of features on computer chips to make faster transistors, as well as increase the storage capacity of computer memory. Unlike in previous subwavelength imaging techniques that use surface plasmons (electron density fluctuations) and that are plagued by losses, the new technique has a different physical cause based on harnessing the spectrum of evanescent fields. As Monzon explained, the smaller wave impedance of the conducting sheet enables researchers to trade definition for amplitude.”What is shown here is that a simple conducting thin sheet acts like a special type of ‘lens’ for evanescent fields, allowing the details of a nearby image to be transferred to the other side of the sheet faithfully (this happens because accurate reconstruction of the evanescent fields of the original image takes place there),” Monzon explained. “Now, it happens that the more conducting the sheet is, the more faithful the reconstruction. However, as we know, the more conducting the sheet is, the more reflective it becomes, resulting in smaller transmitted fields, and a lower amplitude image being formed. Thus better definition can be obtained at the expense of sacrificing amplitude, and vice versa.”This technique could have useful applications, showing that micrometer or nanometer layers of resistive materials can be used to achieve subwavelength imaging in the optical and elusive infrared regions. The method could also be applied to other areas of physics where wave motion exists.”The sharper images, the simplicity of the scheme, and the broadband operation are definite advantages for applications,” Monzon said. “A superlens such as this, capable of creating images of objects or features much smaller than the wavelength of light, could be use in novel types of microscopes, of the super-resolution type. The method can also be used to shrink the size of features on computer chips, so to make smaller transistors that will result in faster computer chips. There is also potential to use this technique in computer memory technology such as read and write devices, so as to be able to access even smaller bits, which can definitely increase general storage capacity/density, and the corresponding data transfer capability.”More information: Cesar Monzon. “Subwavelength Imaging Using Conducting Sheets.” Physical Review Letters, 102, 173901 (2009).© 2009 PhysOrg.com Citation: Novel Superlens Offers a Simplified Subwavelength Imaging Technique (2009, May 11) retrieved 18 August 2019 from https://phys.org/news/2009-05-superlens-subwavelength-imaging-technique.html This document is subject to copyright.

The polymer’s self-healing properties were tested by first cutting it into two pieces and then allowing it to re-from. The authors found that the cut on the polymer film was not discernable after being allowed to “heal” at room temperature for forty-eight hours. The polymer spontaneously healed at low temperatures, -20oC, without the addition of additives that would promote polymerization, something that is unprecedented for an autonomous, self-healing polymer. Finally, the Fe-Hpdca-PDMS polymer showed excellent potential as a model system for artificial muscles. Li, et al. punctured the polymer with a sharp object and marked the area of damage. They then let the polymer self-heal for seventy-two hours. After this time, they applied a square-wave high-voltage signal through electrodes with a high enough potential that the polymer began to deform. However, despite the damage, the polymer did not show a dielectric breakdown, even at the location where it was punctured. This polymer has many properties that make it a compelling model system for an artificial muscle. It displays high stretchability and flexibility. It self-heals and has a high dielectric strength. The polymer can be tuned by changing the ligand-to-metal molar ratio as well as adding functional groups to the ligand, two things that the authors report could be explored in future studies.

Credit: Zhenan Bao The Fe-Hpdca-PDMS polymer showed remarkable mechanical strength, stretchability, and recovery. When the polymer was stretched, then allowed to rest for an hour, and then stretched again, it showed almost full recovery of its original shape. It also showed recovery after a cyclic stress test. When the polymer was subjected to stretching for an hour, it took a little longer to recover and did not quite return to its original state. Notably, the authors report that their polymer can withstand a much higher strain before breaking than typical crosslinked PDMS polymers or reported elastomers. This document is subject to copyright.

(Phys.org)—Animal muscle needs to be strong enough to endure strain; it must also be flexible and elastic; and it is self-healing. Finding a polymer that has all of these properties has proved challenging. However, researchers from Stanford, Nanjing University, UC Riverside, Harvard, and the University of Colorado have reported the synthesis of an elastomer that mimics the properties of animal muscle. Their polymer, is also stable at room temperature and not sensitive to water. Their work appears in Nature Chemistry. Efforts to create polymers that mimic the properties of biological muscle have come short of being practically useful. Often the bonding involved in making these polymers must be sufficiently strong to serve as actuators, but weak enough for reversible self-healing. Many models, to date, involve hydrogen bonding, but hydrogen bonds are sensitive to water. Li, et al. have, instead, exploited metal-ligand interactions as a way to mimic muscle properties.The ligand 2,6-pyridinedicarboxamide (pdca)binds to Fe(III) via the pyridyl nitrogen and the nitrogen and oxygen on the carboxamides. Two pdca molecules coordinate to one Fe(III) atom through six coordination sites. Two of the sites are strong bonds (the pyridyl), two sites are “medium” strength bonds (the amides), and two are weak bonds (the carboxyl). Calculations of bond strength show that the strong bonds are similar to covalent bonds, while the weak Fe-O bonds are similar to hydrogen bonding. This multi-bonding structure, as it turns out, provides an excellent framework for making an elastomer.The ligand was then tethered to a poly(dimethylsiloxane), or PDMS, polymer backbone. Two of these polymer strands were held together through a coordinated Fe(III) atom. Force calculations of the PDMS-tethered, crosslinked polymer confirmed that by having bonds of multiple strengths next to each other, the weaker bonds can readily break and re-form, which is conducive for stretching and self-healing. But the Fe(III) can remain near the ligand through the stronger coordination sites, allowing for rapid re-formation after unfolding.

A highly stretchable autonomous self-healing elastomer, Nature Chemistry (2016). DOI: 10.1038/nchem.2492AbstractIt is a challenge to synthesize materials that possess the properties of biological muscles—strong, elastic and capable of self-healing. Herein we report a network of poly(dimethylsiloxane) polymer chains crosslinked by coordination complexes that combines high stretchability, high dielectric strength, autonomous self-healing and mechanical actuation. The healing process can take place at a temperature as low as −20 °C and is not significantly affected by surface ageing and moisture. The crosslinking complexes used consist of 2,6-pyridinedicarboxamide ligands that coordinate to Fe(III) centres through three different interactions: a strong pyridyl–iron one, and two weaker carboxamido–iron ones through both the nitrogen and oxygen atoms of the carboxamide groups. As a result, the iron–ligand bonds can readily break and re-form while the iron centres still remain attached to the ligands through the stronger interaction with the pyridyl ring, which enables reversible unfolding and refolding of the chains. We hypothesize that this behaviour supports the high stretchability and self-healing capability of the material. © 2016 Phys.org Researchers create super stretchy, self-healing material that could lead to artificial muscle Journal information: Nature Chemistry
For all dog owners out there, your canine friends are paying attention to what you say and do and they’ll remember too. It will be a delightful discovery for dog lovers to know about the findings of this study.A new study has suggested that just like humans, dogs too have “episodic memory” – the ability to remember and recall events from the past. The study revealed that dogs can recall a person’s complex actions even when they don’t expect to have their memory tested. “The results of our study can be considered as a further step to break down artificially erected barriers between animals and humans,” said Claudia Fugazza from Eotvos Lorand University (ELTE) in Budapest, Hungary. Also Read – Add new books to your shelfFor the study, the team first trained 17 dogs to imitate human actions with the “Do as I Do” training method, in which dogs watch a person perform an action and then do the action themselves. For example, if their owner jumps in the air and then gives the “Do it!” command, the dog would jump in the air too. Next, the dogs were trained to lie down after watching the human action, no matter what it was.After the dogs had learned to lie down reliably, the researchers surprised them by saying “Do It” and the dogs did. The dogs were then tested in that way after one minute and after one hour. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe results showed they were able to recall the demonstrated actions after both short and long time intervals. However, their memory faded somewhat over time, the researchers observed. The same approach can most likely be used and adapted in a wide range of animal species, to better understand how animals’ minds process their own actions and that of others around them, the researchers noted. The study published in the journal Current Biology.
Sanjay Barot’s canvasses come alive with the beauty of fine details and meticulous moorings. Treatment and finesse are paramount in these works brought by Ruskshaan Art Mumbai. Barot’s eight works at are an epitome of devotion and distinct allegories in time. “Every canvas is enclosed or mounted with a wooden frame (differently constructed for each canvas) that has been lovingly treated with images, color, layers and texture ,” says Rukshaan Krishna . ” For example, people known and unknown, particularly those that have managed to make a mark in society and rise through the legacy of life have been portrayed on the frame. These wooden frames work as frames of construction for the work and also as the entry point of the society that Sanjay has painted for his viewers.” The artist asserts that these can be read as the ‘final impressions’ that have been culled out from the chaos in the canvas. The chaos on the canvas is patterned by bold lines that have been layered almost a hundred times along with passages that provide space for the playing out of truths that are personal to the artist. And some, we as viewers may empathize with.Barot speaks of his sensibility, and says: ” My creative process is really like my beliefs. They have travelled with me from when I moved from my village in Kapadvanj to the city that I now live in and love, Baroda. Layers and layers. I return to my hometown every 6 months and with every visit, the roots get stronger and help me cope with the chaos of city life.” However, it is only upon drawing closer to the canvas that one can experience the interesting interplay of man and his moments, architectural forms and objects from his beloved hometown and socio-political incidents that have had a bearing on the artist.Rukshaan Art has credentials of commitment rare to see in the modern day art world practices where greed and commerce drive every act. Rukshaan Art hosts works of contemporary artists who are based in or have studied at or work in Baroda, Gujarat. Gallery owner Rukshaan Krishna is the reason behind Baroda March, a decade-old tradition wherein close to 50 ‘Barodian’ contemporary artists showcase their works at the Coomaraswamy Hall, at Mumbai’s Chhatrapati Shivaji Maharaj Vastu Sangharalaya every March. Artists from Baroda, opines the brilliant and deeply admired and respected, Rukshaan have high integrity. Recently she had a historic culling of the works of the 80 year old doyen Jyoti Bhatt who is a legend in the world of intaglio as well as photography. “These artists are in constant conversation with each other. As a result, there’s learning and encouragement. They are not proud but have their pride. They also care about the career graphs of one another,its unheard of in the art community elsewhere.”
