First-of-its-kind Study: Use Of Computer-assisted Colonoscopies Reduces Rate Of Missed Lesions

Scientists from Nanyang Technological University, Singapore (NTU Singapore), in collaboration with clinicians at Tan Tock Seng Hospital (TTSH) in Singapore have developed a novel method that uses artificial intelligence (AI) to display screen for glaucoma, a gaggle of eye diseases that could cause imaginative and prescient loss and blindness by way of damage to the optic nerve at the back of the eye. The AI-enabled method makes use of algorithms to differentiate optic nerves with glaucoma from those which can be normal by analyzing stereo fundus pictures-multi-angle 2D pictures of the retina which might be combined to type a 3D picture. The automated glaucoma diagnosis technique developed by NTU and TTSH, described in a research revealed in the peer-reviewed scientific journal Methods in June 2021, could potentially be utilized in less developed areas the place patients lack access to ophthalmologists, stated the scientists. Glaucoma is often referred to as “the silent thief of sight” as it’s often asymptomatic till latter levels, when prognosis is poor. When examined on stereo fundus photos from TTSH patients undergoing expert examination, the AI method yielded an accuracy of ninety seven % in diagnosing glaucoma.

In case you needed to personal a Nintendo Switch, you in all probability have one by now, until you have been waiting for the lengthy-rumored Pro model. An even bigger display screen and better battery life are each boons for cell players. It does, nonetheless, pack an even bigger gorgeous OLED display, higher battery life (despite what seems to be the identical internal components) and a slightly extra trendy design. That means fewer bezels, a kickstand you would possibly really use and a redesigned dock. Each the original Swap and the Lite are cheaper and supply largely the identical gaming expertise – in the event you play by way of a Television, it’s exactly the identical. But is it sufficient for you to stump up $350, especially when we’re all ready for Nintendo to announce a more notable console improve. The biggest question is: Who is that this for? For the early adopters – or handheld players – the OLED mannequin appears extra engaging. Sadly, the OLED Swap, which we put by its paces right here, will not be the 4K-upscaling, subsequent-gen Nintendo console we dreamed of.

We understand this as a biological analogy for an electrical impulse. Nerve impulse is difficult work. This severely limits the speed of sign transmission in biological tissues. It will be significant that, in its deep bodily essence, a nerve impulse is reasonably a mechanical work, and never an electrical signal in any respect, as many think. A nerve impulse is a pointy movement of sodium. Potassium ions throughout the outer membrane of a neuron utilizing potential-dependent ion channels. This course of will be in comparison with the successive falling of a observe of cards or dominoes. After each nerve impulse, the neuron should return the ions again to their authentic positions. In our instance, this is how to build a observe from cards or dominoes once more. In reality, this isn’t at all the case. It is sort of a gradual walk. The signal travels alongside non-myelinated small-diameter fibers at a pace of only one meter per second. For bigger myelinated fibers, the pace increases to 45-60 kilometers per hour.

Concentrate on the business downside: “Look for places the place there may be already a number of untapped information,” says Sivasubramanian. Give attention to the information: Sethi recommends adopting a “fashionable knowledge platform” to produce the gasoline that makes AI and ML work. They should also be capable of articulate how their technology helps the corporate’s values, whether those values are variety and inclusivity, worker well-being, buyer satisfaction, or environmental duty. In addition, managing data can take up a majority of the time of AI teams, says Sivasubramanian. Work intently with the enterprise: “IT delivers the infrastructure to mannequin the info, while subject material specialists use the fashions to search out the correct options,” says Arthur Hu, senior vice president and CIO at Lenovo. Deal with AI bias or how to write a policy on AI fairness. Humans are on the core of each AI system and may maintain ultimate management, which is why their proper coaching, at every leadership stage, is crucial.” This contains properly-centered coaching and consciousness, says McClean. “IT leaders and employees ought to learn the way to consider the moral impacts of the expertise they’re developing or operating. AI, which combines AI adoption, AI ethics, and workforce development,” says Featheringham. “Ethical and accountable AI development and deployment depends on the people who contribute to its adoption, integration, and use. AI options that work for humans also requires understanding how people work,” says Nevala. “How can humans partaking with AI systems influence their habits and performance? Firms don’t want everybody to learn to determine.
