WILMINGTON, MA — Below is a recent reminder from the Wilmington Recreation Department:Signup for a fun afternoon of arts and crafts with our Dreamcatcher class on Wednesday, August 14, 2019. Open to kids entering grades 3-6.In some Native American cultures Dreamcatchers are handmade wall hangings placed where a person sleeps to ensure good dreams.When a person goes to sleep, the Dreamcatcher will attract all dreams. Bad dreams get trapped inside the web; good dreams pass through. In the morning light, bad dreams dissolve and disappear.In this class you will stencil a picture of a Dreamcatcher on wood using wood stain and paint. All supplies included.To register, visit https://www.wilmingtonma.gov/recreation, call 978-658-4270, or stop by Town Hall, Room 8.

Seven Things You Didnt Know About WhatsApp WhatsApp has recently been pushing out several updates to enhance the user experience of more than a billion users worldwide. As a part its recent efforts to maximise user engagement, the Facebook-owned messaging app introduced new features, but it has been mum on the topic of dark mode for WhatsApp.One of the most anticipated and requested features of all time is the dark mode for WhatsApp. While several social media apps have already started offering the nifty feature, WhatsApp has refrained from it for unknown reasons. Dark mode in apps is bound to increase battery life, and it makes a lot of sense for WhatsApp considering a large amount of time is spent on it.With the rise of AMOLED displays in smartphones, having a dark mode for most popular apps makes a lot of sense. Rumours about WhatsApp getting the lauded dark mode have been swirling around for over a year now but without official confirmation.What if we told you there’s a way to get dark mode enabled in WhatsApp, sort of. Users can enable dark mode on WhatsApp for Android and iOS before the official release without undergoing any major technical steps like jailbreaking or rooting the phones. WhatsApp dark mode trickpixabay.comThe only requirement to get dark mode on WhatsApp is to have the latest operating systems. On Android phones, users must be running the Android Q, which is currently in beta, and iPhone users must make sure they have the iOS 11, according to Business Today.Enable dark mode on WhatsApp for AndroidStep 1: Enable the native dark them on Android Q by going into Settings > Display > DarkStep 2: Apply Dark theme to all appsStep 3: Enable “Developer Options” under Settings > About Phone > tap on Build Number seven timesStep 4: Go back to the Settings page and select Developer options and turn on “Override force-dark.” This will apply dark theme to all apps.Doing this will apply the dark theme effect on WhatsApp, but the chat window will still have the standard wallpaper or the one you’ve selected. The next step is to go into the app settings > Chats > Wallpaper and choose a solid dark colour from the given options. WhatsApp dark mode spotted under testWABetaInfo (screen-shot)Now you’ve mimicked dark mode on WhatsApp without having to wait for the official rollout. But there are limitations to this trick as it works only on Android Q phones and not a lot of phones currently run Google’s latest OS.Enable dark mode on WhatsApp for iPhoneLike in the case of Android, iPhone users can also mimic the dark theme on iPhones. To do so, users must rely on an iOS 11 feature called “Smart Invert” that reverses the colours of the display. In our personal opinion, it’s not the most effective way to get the dark theme on WhatsApp, but it’s the only one iPhone users get at the moment.

Harun-ur-Rashid. Photo UNBA court Sunamganj on Monday rejected the bail petition of Bishwambarpur upazila chairman Harun-ur-Rashid and sent him to jail in a rape case.Md Zakir Hossain of Women and Children Repression Prevention Tribunal passed the order when Harun surrendered to the court asking for bail, said assistant public prosecutor Khairul Kabir.According to the case statement, Harun called the victim to his upazila parishad office to give her a sewing machine on 26 September and raped her there.Later, the victim woman filed a case against the chairman with Women and Children Repression Prevention Tribunal that same afternoon.
Hauwa (L) and Ya kaka, identified only by their first names, former captives of Boko Haram militants in Nigeria and now acting as advocates speaking out on behalf of other captives and survivors, pose for a portrait after they appeared on a panel dealing with issues of violence against women in New York City, US on 13 March. Photo: ReutersBoko Haram militants freed scores of kidnapped Nigerian schoolgirls on Wednesday, but some of the released students said five of their schoolmates had died in captivity and another was still being held. The Islamist fighters, some of them shouting ‘God is greatest’, drove the students back into the northeast town of Dapchi in a line of trucks in the morning, dropped them off then left, witnesses told Reuters.“Five among us taken away were dead. One is still with them because she is a Christian,” one of the freed girls, Khadija Grema, told Reuters.Dapchi resident Muhammad Bursari said his niece Hadiza Muhammed, another of the freed girls, had told him the remaining student was still in captivity because she had refused to convert to Islam.Witnesses said more than 100 of the 110 girls seized on 19 February were returned, though the government issued a statement saying 76 girls had been freed in an “ongoing process”.The kidnapping of the girls aged 11-19 was the biggest mass abduction since Boko Haram took more than 270 schoolgirls from the town of Chibok in 2014 – a case that triggered international outrage.The Dapchi abduction has piled pressure on President Muhammadu Buhari, who came to power in 2015 promising to crack down on Boko Haram’s nine-year-old insurgency and could face the voters again next year.
Indian police have arrested ten university students for playing PUBG, the hugely popular smartphone game described by one minister as a “demon in every house”.The arrests occurred Wednesday in western Gujarat state, where local authorities enforced an outright ban on PUBG last week over concerns about its impact on the “behaviour, conduct and language” of those playing it.The students were released on bail later the same day, police inspector VS Vanzara said Thursday.Another police official, Rohit Raval, told the Indian Express newspaper the game was “highly addictive and the accused were so engrossed in playing” they did not even see police approaching.Gujarat is the only Indian state to ban the game — which has been downloaded more than 100 million times around the world.But concern has been raised in other parts of the country, where close to half a billion people are online and cheap smartphones and data plans are bringing more first-time users into the digital realm.Parents and educators say the game incites violence and distracts students from their studies.A minister in coastal Goa state described the PUBG as “a demon in every house”. Last month, a mother complained to prime minister Narendra Modi about her son’s addiction to online games during a public interaction and he replied: “Is this the PUBG one?”Often likened to the blockbuster book and film series “The Hunger Games”, PUBG is free to download and pits players stranded on islands against one another in a virtual fight to the death.
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.
