TCL Phone launches typically run on a predictable cycle. A new Samsung Galaxy S phone launches in the first quarter, while new iPhones make their debut in September. But BlackBerry Mobile, run by Chinese consumer electronics giant TCL, is bucking its usual trend this year and won’t be launching a new flagship phone in the summer. Francois Mahieu, general manager of BlackBerry Mobile, said that a new version of its BlackBerry Key franchise won’t appear for at least six months.That means its existing Key2 will be on the market for at least 14 months, an unusually long time for a phone. TCL is keeping the line fresh with minor updates, like the introduction of a new red color and boost in storage on Sunday at the MWC Barcelona trade show.

One key upgrade driver could be 5G, but Mahieu said in a prior interview that there won’t be a BlackBerry running on next-generation wireless technology in 2019. He did keep the possibility alive for a 2020 5G BlackBerry though.

BlackBerry Mobile isn’t likely to start a trend — after all, it remains a niche player as one of the few companies offering a phone with a physical keyboard — but its move reflects a slowing market that’s seen declining phone sales and consumers reluctant to upgrade as frequently as they did in the past. Mahieu insists BlackBerry is still growing, but notes that the marketplace is crowded. He also noted that BlackBerry customers — like everyone else — are hanging on to their phones longer. As such, he didn’t feel the need to hit the annual upgrade deadline.

Narendra Modi and Rajinikanth.PR HandoutRajinikanth has made a u-turn on his political stand ás he has extended his support to the BJP in the forthcoming Lok Sabha elections. The Tamil superstar has predicted that the saffron party will register a thumping win in the polls and Narendra Modi would be the Prime Minister of India once again.Explaining the stand behind changing his stand and endoring Narendra Modi, Rajinikanth said, “I thought of staying away from politics as I could not give necessary attention to build my party. I had this belief that it could be a cakewalk for Modi at the centre. But looking at the way opposition parties are vying for his blood, I feel the need to put my weight behind an honest man who is toiling hard to put a great picture of country in the world map,” the Tamil superstar said.Is he supporting him out of fear that Modi might fail to become the PM again? “No, I am cent percent sure that the BJP will secure 300+ seats on its own. The reason why I am endorsing him is because there are lots of lies that are being spread about him. I believe a lie told 100 times might seem like the truth to the people. Hence, I decided to support him,” he said.”I am among the millions of Narendra Modi fans who want him to be the Prime Minister again. I may not be very comfortable with BJP’s ideology and endorse everything that do, but surely I back him for the India’s political post. His policies might have failed to yeild desired results and some could be called failures, yet nobody can question his sincerity and courage to take bold steps,” Rajinikanth claims.Interestingly, Rajinikanth seems to be not happy with the AIADMK and his liking has shifted towards the DMK leadership. “At present, I feel MK Stalin is the best leader among the lot in Tamil Nadu. I see a future for him in the state politics.” It has to be noted that the Dravidian party is having alliance with the Congress in the forthcoming Lok Sabha election and has been critical about Modi’s policies.However, Rajinikanth is prepping up for the Tamil Nadu assembly election in 2021. “By then, we would be in a position to contest in all the constituencies in the state. The BJP’s position in the state is negligible and there is a vaccum in politics after the demise of two stalwarts like J Jayalalithaa and M Karunanidhi.Rajini’s desire to foray into politics got new lease of life after J Jayalalithaa’s death. Months after she passed away, Rajini indicated that he was ready for the politics. To everybody’s surprise, he released a press release recently stating that his party Rajini Makkal Mandram was not endorsing any party and requested his party men not to identify with other parties.Did you believe this news?Happy April Fools’ Day. This story means no harm and is only meant to be a good-natured April Fools’ prank. We hope you had a laugh and here’s wishing you a wonderful day.
SS Karthikeya with his mother and father SS RajamouliTwitterAfter staying away for quite some time, SS Rajamouli’s son SS Karthikeya is back on Twitter and he has showered praises on the trailer of Samantha Akkineni’s Oh Baby and the teaser of Prabhas’ Saaho.SS Karthikeya, who has worked as line producer for the Baahubali film series, often shares his review of movies and their promos on Twitter, where he boasts of 364 followers. His views matter a lot of filmmakers as they help their film reach to more number of people. But he had been staying away from the social media for a couple of months due to some unknown reason.This morning, SS Rajamouli’s son took to his Twitter page to say that he is away from it, but he is following every update in the industry. SS Karthikeya tweeted, “Been away from Twitter for while now – but obviously following everything that’s happening. #Saaho Teaser was just mind blowing And films like #AgentSaiSrinivasaAthreya #Mallesham #Brochevaruevarura entertaining our audience. cont… (sic).”In his next post, SS Karthikeya showered praises upon Samantha Akkineni and the trailer of her next film Oh Baby. He tweeted, “So much new talent – feels like we are a very rich industry. And then comes the #Baby trailer. @Samanthaprabhu2 just never fails to amaze us. Keep going Sam! Last but not the least – inkoka telugodu national wide janda pathadu. @imvangasandeep .”SS Karthikeya is currently work in SS Rajamouli’s upcoming movie RRR starring Junior NTR and Ram Charan. He says that its shoot is going on at a brisk pace. The Baahubali line producer tweeted, “Telugu cinema and talent shining bright. Keep it coming guys! And meanwhile #RRR update – Shoot going in full swing. Done with very satisfying sequences. Short break for a week now. Love you all.”
Baltimore City Council has finally decided – not to decide yet on the $15 an hour minimum wage. The Council voted 8(yes) 6(no) to 1(abstain) to send the bill back to committee this week. Council chair Bernard C. ”Jack” Young had just started a roll call vote on the bill when the bill’s sponsor, Mary Pat Clarke (District 14), stood to request that the legislation be sent back to committee.After the council meeting ended, Clarke explained to reporters that she had recently been contacted by the National League of the Blind and Disabled with concerns about the bill. She wanted to ensure the group had sufficient time to work through their issues with city council.But Clarke was also under no illusions about the uncertainty surrounding the bill’s chances for passage given the current city council. “The City Council is still divided,” said Young who unsuccessfully sought a compromise of $11.50 an hour.Clarke and City Council Labor Committee Chair, Robert Curran did not rule out waiting until the new Council session starts in December to re-introduce the legislation.
For the first time, physicists have entangled a qubit with a “qutrit” – the 3D version of the 2D qubit. Qubit-qutrit entanglement could lead to advantages in quantum computing, such as increased security and more efficient quantum gates, as well as enable novel tests of quantum mechanics.

The research team, composed of physicists from the University of Queensland, the University of Bristol, and the University of Waterloo, has published its results in a recent issue of Physical Review Letters. The researchers made qutrits with biphotons (two correlated photons), resulting in “biphotonic qutrits.” Then, they entangled these qutrits with photonic qubits (made with one photon) using a combination of linear optic elements and measurements.A qutrit, just as it sounds, is the quantum information analogue of the classical trit. Due to its quantum mechanical nature, a qutrit can exist in superpositions of its three basis states. This is similar to how a qubit can exist in superpositions of its two states. Because of the qutrit’s 3D nature, though, it can carry much more information than the qubit. (A string of n classical bits holds 1n states, a string of n qubits holds 2n states, and a string of n qutrits holds 3n states.)Many researchers have investigated the possibilities of entangling a qubit and qutrit, hoping to develop a valuable tool for improving quantum computing and exploring novel quantum phenomena, among other things. The authors’ result now makes such theoretical proposals experimentally testable.“For me, the significance our paper is about how entangling systems to a qubit can be a great way to manipulate that system,” co-author Benjamin Lanyon of the University of Queensland told PhysOrg.com. “In our example, we use this technique to dramatically extend the range of possible transforms on qutrits – these higher dimensional quantum information carriers, which offer loads of advantages, but are otherwise really difficult to handle.”In their study, the researchers show that qubit-qutrit entanglement can be a useful resource to manipulate the difficult-to-handle qutrits. The scientists built a non-linear qutrit polarizer, which involves creation of the entanglement and destructive measurement of the qubit. The result is to temporarily remove a single qutrit state from the qutrit’s superposition. Lanyon explains that this is an example of a measurement-induced nonlinearity (MINL), which is known to be an extremely powerful tool to manipulate qubits and realize an optical quantum computer. “Measurements on the output of optical circuits built from only linear elements (such as beamsplitters, phase shifters and mirrors) can give rise to a non-linear evolution of the input optical field, i.e. for all intents and proposes, the photons seem to have interacted,” said Lanyon. “This is surprising, since photons do not naturally interact in these systems, and the effect is called a measurement-induced nonlinearity. In the context of our study, the MINL gives rise to the non-linear evolution required to generate entanglement and remove a single logical state from a qutrit superposition.”He also gave a visual description. “Consider that there are a number of different paths that the photons could take through the optical circuit,” he said. “As in the double-slit experiment with electrons, the photons take all these paths at once, and, at the output, we end up with a large superposition. Now let’s make a measurement of the whole (or part) of the output state. Certain results mean that certain paths were not taken – and therefore we can get rid of paths this way, conditional on getting certain measurement outcomes. Very clever measurements can leave you with a path history that results in entanglement.”The researchers also propose a number of extensions to their work. For example, a pair of entangled qubit-qutrit states could be used to create qutrit-qutrit entanglement, which would first require entangling the two qubits. High-brightness single-photon sources currently in development will help with these kinds of future experiments. The researchers also propose that using MINLs as a manipulation technique is not limited to photons, but can be applied to any type of bosonic quantum information carrier.The scientists predict that higher dimensional entanglement will have applications including optimizing security in quantum information systems, and increasing channel capacity for quantum communication, among other uses.

To address this issue, a team of researchers from Stanford University in the US, the Samsung Advanced Institute of Technology in Korea, and Sungkyunkwan University in Korea, has greatly improved the performance of n-channel organic semiconductors in transistors. They demonstrate that their transistor achieves the highest mobility for n-channel organic wire transistors known to date, and is comparable with the best p-channel organic wire transistors. Their fabrication method offers controlled alignment and density of the wires, which helps improve the overall device performance. The results are published in a recent issue of PNAS.“N-channel transistors are needed for complimentary circuits consisting of both p- and n-channel transistors,” coauthor Zhenan Bao of Stanford University told PhysOrg.com. “Such circuits consume less power and are easier to design then the ones with p-channel transistors only. They are less common because electrons flowing in these transistors are easily trapped by ambient oxygen and moisture. Therefore, special molecular design and synthesis is needed and only a few classes of molecules show good air-stable n-channel performance.”In their fabrication approach, the researchers used a solution fabrication method to assemble the organic microwires. Certain organic conjugated molecules, when placed in a hot concentrated solution, readily assemble into wires upon cooling or addition of a “bad” solvent (a solvent that the molecule is not readily soluble in). By controlling the cooling speed and solvent mixing ratio, the researchers could tune the diameter of the wire (in the range of tens of nanometers) and the length of the wire (from several millimeters to several tens of micrometers). Upon completion, the microwires exhibited a structurally perfect single-crystalline nature, with different locations of the same wire showing the same diffraction pattern geometry. In addition, the orientation of the molecules (pi-stacking) along the long axis of the microwires improved the wires’ charge transport efficiency, and overall wire performance.Next, the researchers used a filtration-and-transfer (FAT) alignment method to control the alignment and density of the microwires being deposited on the transistors. In general, organic microwires are difficult to work with due to their fragility, and they’re easily damaged by handling. In the FAT method, the microwires are aligned by fluid flow through a mask in a simple vacuum filtration setup. The method could successfully produce dense films of aligned and undamaged microwires, which is important for achieving a high and uniform current. Unlike most other assembly methods, the FAT method could also create multiple microwire patterns in different directions, simply by using an appropriate mask. As the researchers explained, the high mobility of the new n-channel organic transistors can be attributed to the high level of structural perfection of the microwires, along with good alignment and high density of the microwires on the transistors. Hopefully, this approach will lead to the fabrication of high-performance organic electronic devices, in addition to the transistors shown here. Zhenan added that solar cells and sensors are potential devices, and that the method should be applicable to inorganic nano- and microwire alignment, as well.More information: Joon Hak Oh, et al. “Solution-processed, high-performance n-channel organic microwire transistors.” PNAS, April 14, 2009, vol. 106, no. 15, 6065-6070.Copyright 2009 PhysOrg.com.

(PhysOrg.com) — Organic semiconductors are promising building blocks for many devices, from LEDs to transistors, offering potential advantages such as cost-effectiveness, flexibility, and high performance. Currently, most research in organic semiconductors has focused on p-channel semiconductors, which transport positively charged holes, rather than n-channel semiconductors, which transport negatively charged electrons. The choice of semiconductor depends on the application, and many applications require a combination of both types. However, the few n-channel semiconductors that exist today have performance that lags considerably behind their p-channel counterparts.
